Teach all theories? Yes, if it's actually a theory

There was an article in the Hamilton Spectator a few days ago about how evolution not being taught in Ontario schools until Grade 12 biology, a course which is not mandatory. As a result, we have students in Ontario universities that have never learned about evolution or natural selection and think that it means "people came from monkeys". In today's Spec, there is a letter to the editor in response to this article, which states:

Evolution may be a valuable lesson but it is still a theory. The title seems to imply that Darwinian theory equals truth.

The teaching of 'intelligent design' and 'creationism' are theoretically just as valid.

The teaching of all three in a science curriculum would help students to learn, analyze, discern and decide for themselves what data is relevant and to find their own truth.

Isn't that the best education?

I just finished writing a response and emailed it to the Spec. My response:

The writer is confused about the use of the word "theory" with respect to the theory of evolution. Evolution is a fact -- scientists have observed it happening. The theory of evolution describes why and how it happens, not whether it happens.

A scientific theory is not just a guess. The theory of evolution is no more a guess than the theory of gravity. We may not understand all the details of how evolution works, but there is no question that it is happening.

Intelligent design, on the other hand, is pseudo-science that is not supported by any facts, only religious faith.

We'll see if it gets published.

NLL Playoff Picks – Round 1

East

Rochester vs. New York

Rochester started the season 0-4 and just looked really bad, but they fought hard to recover and beat Philadelphia in a must-win game to make the playoffs, which is a testament to rookie coach Paul Gait. They have survived the loss of John Grant and Scott Evans, plus Pat O'Toole for a few games. On the negative side, we all knew Gary Gait wouldn't be the multiple-MVP-winning Gary Gait from years gone by, but I think he was even less impactful than expected. Gait didn't even make the top 50 in scoring. He missed five games, but even if you extrapolate out to 16 games, he'd only be tied for 35th. After Williams (#6) and Evans (T12), the third top scorer on the Knighthawks was Jason Henhawk, tied for 57th. The Titans have six scorers in the top 37.

New York was in second place all year, but ended up tied with both Buffalo and Boston and won the East on tie-breakers. Matt Vinc is one of the best goaltenders in the league, and Casey Powell ended up 8th in the league in scoring despite only playing 13 games. Extrapolating his point total to 16 games you end up with 104, which would have tied him with Dan Dawson for second. The Titans took two of three from the Knighthawks during the regular season, but the first win was early in the season when a struggling Hawks team only allowed them 8 goals, so you could almost call the season series even.

Prediction: New York in a close one

Boston vs. Buffalo

Another toughie. Two strong offensive teams, two outstanding goalies. Boston has nothing to prove – nobody though they'd make it this far – but Buffalo lost their last two games (their last to these same Blazers) and with that, their lock on first place. The days of Buffalo losing games because they took too many stupid penalties are long gone, and I think the Bandits will be back with a vengeance.

Prediction: Buffalo

West

Colorado vs. Calgary

Calgary only lost four games all season, but one of them was to the Mammoth. (Another one, inexplicably, was to the lowly Toronto Rock.) King and Campbell have been the best one-two goalie combo in the league this year, and Josh Sanderson has made Calgary fans forget Lewis Ratcliff. Colorado, on the other hand, finished the season with a win over Edmonton but lost seven of nine before that and as any Star Trek fan will tell you, losing Seven of Nine is a very bad thing indeed. Leyshon and Palidwor played admirably, but the loss of Gee Nash was just too much. Calgary shouldn't have a problem getting to the west final again.

Prediction: Calgary

San Jose vs. Portland

I find it difficult to go against Colin Doyle's team in the playoffs. I've seen him step his game up a notch (or more) when the games matter the most too many times to think he might fold under pressure. His unprecendented three Championship game MVP awards are a testament to that. San Jose didn't have a great season, but they won four of five near the end of the season, at the same time that Colorado was losing five of six. I think San Jose will take it, but having said all that, they'll have trouble getting by Calgary.

Prediction: San Jose

If I was forced to make predictions on round two, I'd have to take Buffalo over New York and Calgary over San Jose, resulting in a rematch of the 2004 Championship – Buffalo in Calgary. I'll have to give Calgary the edge in another close one. Ladies and gentlemen, your 2009 NLL Champions, the Calgary Roughnecks.

Top ten reasons why being a Rock fan is better than being a Bandits fan

1. Getting tickets to a Rock game is getting easier, while getting tickets to a Bandits game is getting harder
2. No annoying cheering and yelling during games – much quieter while you are sending email on your Blackberry
3. Orange shoes are distracting
4. Same coach and GM for seven years? Where's the fun in that?
5. No counting lessons ("1, 2, 3, ..., n, WE WANT n+1!") or spelling lessons ("B O X") during Rock games
6. Rock fans can look back at the early years when Les Bartley and Jim Veltman led them to multiple championships
7. Mark Steenhuis is greedy – keeps hogging All-Star game MVP and player of the week awards
8. A Bandits player has the same last name as the coach/GM... suspicious. That would never happen in Toronto.
9. Rock coach arrested for beating up an opposing player. Boring Bandits coach could beat up just about anyone on the planet, but doesn't.
10. Weekends free in late April and May

Eight of Five

I have posted a couple of times in the past about J.P. Ricciardi and whether he should be fired. First I complained about a couple of stupid moves that he made. Then I decided that he definitely should be fired. The last time, I was questioning my previous decision. Then when they let Burnett go and did nothing else in the off-season, I decided (though I guess I didn't post anything to this effect) that Ricciardi's time was over. Now they've started the season (a season with zero expectations) at 10-4 and have looked seriously awesome. Lind, Hill and Rolen are all hitting above .325, while Overbay, Wells, Snider, and Scutaro are all above .280. Everybody listed above has at least two homers after 15 games, and everybody listed above except Wells was acquired or drafted by Ricciardi. Ricky Romero, another Ricciardi draftee, is 2-0 with a outstanding 1.71 ERA and 1.10 WHIP. Shaun Marcum (also drafted by Ricciardi) and Dustin McGowan are out for the season because of injuries, but injuries aren't J.P.'s fault and if those two were healthy, the Jays would have a pretty impressive rotation. So maybe Ricciardi does know what he's doing.

Obviously this is really early in the season, and for Romero at least, very early in the career, so it may not mean anything. The Jays are on pace to win 115 games. Do I think that will happen? Not a chance, but I'm certainly enjoying watching them right now.

Then again, the only team with more wins than the Jays are the 11-1 Florida Marlins, and the World Series Champion Phillies are under .500.  Last year, Tampa Bay won the East and the Yankees didn't make the playoffs. All of these put together make a compelling argument that the end of the world is very close at hand. Sinners repent.

There's been a lot of talk over the last year or two among Jays fans, many of whom think that Ricciardi has had his chance and deserves to be fired, since the Jays are no closer to the pennant now than they were when he took over. J.P. originally said that he had a plan to make the Jays contenders in five years, and we're now into year eight. But has Ricciardi really done a bad job, or does it seem like that because he gave us a hard deadline that he didn't meet? What would we think had J.P. not said anything about how long it might take? Well, as I posted before, he's currently the longest-serving GM that hasn't seen the playoffs. And it's not like we've been close – the Jays haven't had a sniff of the playoffs since 1994. So I think that even if J.P. hadn't given any time deadline, we'd still be calling for his head. But given the awesome start to this season, I'm willing to give him just a little more rope. But unless the Jays get to the post-season this year, he's done. In fact, if the team isn't still in it by the All-Star break – and by "in it" I mean within 2 or 3 games of first place in the East – then that should be it for J.P., and the Jays should start looking for a new GM, preferably someone named Brian.

NLL season prediction results

The 2009 NLL regular season has come to a close, so it's time to look at the predictions I made at the beginning of the season and see how I did.

	Result	My predictions
East
1	New York	Buffalo
2	Buffalo	Philly
3	Boston	New York
4	Rochester	Toronto
5	Philly	Rochester
6	Toronto	Boston
West
1	Calgary	Minnesota
2	Portland	Calgary
3	San Jose	Colorado
4	Colorado	San Jose
5	Minnesota	Portland
6	Edmonton	Edmonton

End result: one correct out of twelve. Ouch. But really, you could argue that I wasn't that far off. Five teams – Buffalo, Rochester, Calgary, Colorado, and San Jose – were all off by only one. As with my mid-season predictions, if you make two swaps my predictions are very close. Swap Philly and Boston (who predicted that they would finish tied for first?) and four teams miss by one and the other two miss by two. In the west, swap Minnesota and Portland and I get four off-by-one's and two correct.

I have a copy of Inside Lacrosse magazine from the beginning of the season, and Brian Shanahan made his picks as well, so let's see how he did:

	Result	Brian Shanahan
East
1	New York	Buffalo
2	Buffalo	Rochester
3	Boston	Toronto
4	Rochester	Philly
5	Philly	New York
6	Toronto	Boston
West
1	Calgary	Minnesota
2	Portland	San Jose
3	San Jose	Colorado
4	Colorado	Edmonton
5	Minnesota	Calgary
6	Edmonton	Portland

Turns out that Shanny's ouch is worse than mine. None right and only four off by one. The best you can do with two swaps would be New York and Rochester in the east, giving him four off-by-ones and the other two off by three. In the west, you could swap Minnesota and Calgary and get two right, and you'd still have two off by one, but then Edmonton is off by two and Portland by four.

Shanny was more confident about Rochester and Toronto than I was and like me, he thought Minnesota would fare better than they did. But how he got Edmonton finishing ahead of Calgary I don't know. In fairness, Shanny's predictions were made before Chicago folded (he had them finishing 6th in the East, between New York and Boston) and therefore before Anthony Cosmo joined the Blazers. They were also made before Paul Gait was hired as Rochester head coach, and before it was announced that the Knighthawks would be missing Shawn Evans for the season.

Maybe Shanny should start reading my blog, instead of me reading his. <grin>

Wii Fit

Our "family present" this past Christmas was Wii Fit. The boys were kind of excited about it, but not thrilled. It wasn't like their reaction when we bought them Star Wars Lego for Wii – that game was a big hit. Since then, however, they've really started to enjoy Wii Fit. It's not their favourite game – that would be the aforementioned Star Wars Lego – but I'd say it's in the top three. Gail and I also enjoy it. There are basically three "modes" to Wii Fit. It can be:

1. a fun game
2. a workout that doesn't seem like a workout
3. a real workout

The balance games may help your overall balance, but they certainly just seem like fun. Or, you can combine the balance games with a couple of the aerobic ones for a bit of a workout. There's a boxing one that combines throwing punches with step aerobics, or there are regular step aerobics and some running ones as well. Or, if you are actually in the mood to work out, some of the strength training and yoga exercises are quite difficult (the "dance" yoga one is the hardest one I've done yet).

Does it compare to an actual weight bench or going for an actual run, whether outside or on a treadmill? Well, not really. But there have been times where the boys are asleep and Gail is either asleep as well or doing something else, and I have some time to myself. Sometimes I read, blog, work, play my guitar, but rarely do I decide to go and work out for half an hour. However, on some occasions I have decided to play Wii Fit for a while and before I knew it, I had worked out for half an hour or more.

People have been trying to making exercising fun for non-fitness buffs for years, so kudos to Nintendo for finally succeeding.

CD Review: Pearl Jam – Ten Redux

I originally bought Pearl Jam's Ten album in about 1991 and have loved it ever since. It's one of my all-time favourite albums, is simply great from start to finish, and even contains one of my favourite guitar solos (on "Alive"). This past week, Pearl Jam released a new version of Ten which contains two CDs – the first is simply the album I have, the second (called Ten Redux) contains remixed versions of every song on the album, as well as a few bonus tracks. This basically means that I just bought two copies of an album I already had.

I didn't plan on buying this new version, figuring it was only for serious die-hard Pearl Jam fans. But Alan Cross talked about it on the Explore Music podcast a couple of weeks ago, and said that the new remixed version is simply amazing, so I ordered it from amazon.ca.

Strangely, Cross said that the changes are "subtle, but obvious – if you listen to it off CD and NOT off a compressed MP3". So on the way into work the other day, I brought the CD with me and listened to it directly, rather than plugging the iPod in. (Ironically, the CD wouldn't play in the player at first. I had to eject it and try it again before it would play. I think the first time I put the disk in, it got caught in the cobwebs inside.) I was a little sceptical that I would hear any difference, given what Cross had said – I figured that if the differences were so subtle that you couldn't hear them from an MP3, then the $69 stereo in my car wouldn't allow me to hear the differences anyway, but it did. I'm not sure I agree with Cross's assessment, since the differences I hear are obvious enough (to someone who's listened to the album enough times) that even with a compressed MP3, you can hear them. I listened to the MP3 version from my iPod as well, and sure enough you can hear the changes. I rip all my MP3's at a variable bit rate, which means that the compression isn't as good (i.e. the files are bigger) but you don't lose as much sound quality. Maybe Cross uses a higher compression rate.

The Difference

Despite sounding oxymoronic, Cross's description of "subtle, but obvious" is exactly right. This not a "director's cut" – there are no new verses, no new solos, and none of the songs are any longer or shorter than the originals. Nothing has been added or removed, and most importantly, Han still shoots first. Most of what they've done is modify the relative volumes of the instruments. In most songs, the rhythm guitar has been turned up during solos -- in a couple of cases, it's been turned up enough that it's harder to hear the solo guitar. There were a couple of relatively quiet sections (like the first time you hear "Why go home?" in "Why Go") where the drums and bass have been turned up a little. In some cases, the background vocals have been turned down. The most obvious specific difference I found was that the "hoo hoo hoo hoo" high-pitched vocals on "Jeremy" have been almost removed. There are a few other smaller changes:

• in "Even Flow" after the line "Where do I stand?", the echo of "stand" is gone
• the bass at the very end of "Why Go" is a little louder, and is sustained just a touch longer, causing the segue into the brilliant "Black" to be a little less smooth than the original.
• the opening guitar on "Garden" has a different tone

There are also six bonus songs included, some of which were previously unreleased. "Brother" and "Just A Girl both" sound like they could have been on Ten, and I might even have included "Brother" over "Deep". "Breath And A Scream" is kind of boring, and sounds like a bonus track, i.e. one that wasn't good enough to make the album. "State Of Love And Trust" isn't bad, and "2,000 Mile Blues" is cool - very Zeppelin-esque. "Evil Little Goat" is only a minute and a half long, but if Eddie Vedder ever sang for The Beach Boys, this might be what it would sound like.

Now if only Pearl Jam could remix their later albums (anything after Vs.) to make me care about them. I loved Ten and really liked Vs. as well but for some reason, I completely lost interest in Pearl Jam after that. No idea why. I have a couple of later albums (Riot Act and Pearl Jam) and I've listened to them a couple of times, but they seem kind of forgettable. But now that my interest in Ten has been rekindled, I'll give them another listen.

Mangled metaphors

Heard on a sports podcast today:

That's the golden slipper that Cinderella was looking for.

Um.... what?

First off, Cinderella had glass slippers, not gold. Secondly, Cinderella wasn't looking for a slipper. In fact, she wasn't looking for anything – it was the Prince looking for the person who fit the slipper.

<shakes head> Sports guys.

Boston 14 Toronto 13

Some comments on tonight's game:

• Watson was a little shaky at the beginning but settled down, and made some very nice stops in the second half. Cosmo was great all night. It seemed that Toronto kept trying to go five-hole on him all night, but there just wasn't a five-hole. That's probably why they asked for the goalie equipment check.
• Most games this season (the home games, anyway), the Rock have started out strong and then slowed down. They played a full 60 strong minutes in the last game, and tonight, the Rock's best quarter was the third, but the 4th was pretty strong too. Overall, other than refusing to shoot the damn ball at times, they played pretty well.
• Like Rochester's Mac Allen in the last game, another bad moustache. "Boston penalty to #12, Jon Durno, two minutes for unruly facial hair."
• After the last goal, I was reminded of the 2001 NLL Championship game in Toronto. The other team (Philadelphia in 2001, Boston tonight) is up by two goals, but the Rock is putting on great pressure. Toronto scores a goal to bring them within one, and I immediately look at the clock to see how much time is left. In 2001, about 1.3 seconds. Tonight, 0.9. Just not enough time and the Rock lose by one.
• Nice to see Cosmo come out and congratulate Dan Ladouceur.
• Jason Clark is new to the Rock, and obviously hasn't read the Rock 2009 playbook. A couple of times when he got the ball near the net, he turned and shot at the net. He doesn't yet know that the way Rock do things in 2009 is to pass the ball around ten or fifteen times, ignoring decent shooting opportunities, before (a) shooting directly at the goalie's chest, (b) dropping a pass, or (c) shooting and missing the net completely. I'm sure by the next game, he will have cleaned up his act a little and gotten with the program.
• There were a couple of goal reviews, all of which were quite obvious on the replay. I thought for sure that McGlone was in the crease on his goal, but replay showed clearly that he was still in the air when the ball went in.
• Rob Marshall is trying so hard to be Steve Toll, but he just can't score. I like him though, he works hard.
• Cosmo twice stopped play when his team needed it by having the trainer come out to look at his equipment. Another skill he learned from Whipper while he was in Toronto.

Dialoguing about language weirdities

A bunch of mini-stories about the English language (about which I have previously opined):

There is no noun in English which cannot be verbed. I received an email the other day that contained the word "dialogue" as a verb: "we would like to dialogue with you...". Why not just say "talk" or "speak"? Or "we would like to have a dialogue with you..." Another example of how verbing weirds language.

Someone on a podcast recently was talking about seeing things from a different advantage point. Sigh.

Ryan asked me a little while ago, "Why can't I have my cake and eat it too? If you can't eat it, what's the point of having it?" I had no answer for him.

In recent years, a lot of people have started using the phrase "going forward". Why? For almost any sentence containing those two words, the sentence means exactly the same thing if they are removed. Same with "all told".

If "it goes without saying", why say it? I actually remember the host of some show like the Oscars or Emmys playing on something like this: he announced that the next presenter "is a man who needs no introduction" and then simply turned and walked off the stage.

Why is it that "I could care less" and "I couldn't care less" mean the same thing? I always use the latter, since the former makes no sense, but people use it anyway.

Cute kid story: When Ryan was very little (maybe two), we found that if we gave him a cup of juice when he bumped himself or fell or whatever, he'd "recover" faster. Not because of any medicinal properties of the juice, more because it distracted him. He'd concentrate (see what I did there? a juice joke) on the juice (apple juice was about the greatest thing in the world to him back then) and forget about whatever hurt. I guess we told him "some juice will make you feel better" one too many times, because after a while he started verbing it himself. He'd fall and then say between tears "Some juice will feel me better".

Some people just don't think

The Guardian, a 188-year-old UK-based newspaper, announced today that they will be discontinuing their paper editions and publishing exclusively on Twitter. While I applaud them for their forward-thinking, I can't help but wonder at the wisdom of the timing of the announcement. I mean, it's April 1st, for crying out loud! How do they expect to be taken seriously when they make an announcement this big on April Fool's Day? Wouldn't it have been smarter to post this announcement yesterday or tomorrow?

People, you really should think before posting stuff like this. I mean, really.

Relation FAIL

I started to lose some confidence in the accuracy of the We're Related application on Facebook today, when I saw this:

So many levels

I'm making spaghetti squash for dinner. I cut the squash open and find that it smells like pumpkin inside, which is not surprising since they are from the same squash family. Ryan happens to be there, so I mention this fact to him. He takes a whiff and agrees that it smells like pumpkin. Ryan happens to be the biggest pumpkin pie fanatic on the planet, so I suggest "Hey, maybe I should make a spaghetti squash pie for dessert? Whaddaya think?" His response, after a couple of seconds of thought:

"That is freaky on so many levels."

Judging a book by its cover

Down Goes Brown has written a scathing review of a book that he hasn't read. In fact, the book won't even be released for six months. But the cover tells you that the authors believe that the Toronto Maple Leafs suck, so how can it possibly be a good book? Now, I'm a Leafs fan, so what I'm going to say here might sound like heresy, but I'm gonna say it anyway. DGB, perhaps this is news to you, but here it is: The Leafs do suck, and have sucked for much of the past forty years. There. I said it.

Have they sucked every single year in that time? No, definitely not. They made the conference finals four times between 1993 and 2002. And are they the only team to not have won the Cup in that time? No, of course not. But every other original six team has at least made the Stanley Cup finals since 1967, and all but one have won the Cup in that time (in fact, Montreal has won it ten times (ouch, typing that was physically painful)). The Leafs have not made the finals since the Original Six were the only six. The Oilers and Islanders didn't exist the last time the Leafs won it all, and they've won it nine times between them. Carolina, Anaheim, and Tampa freakin' Bay have won Cups since then. The Leafs have had some good seasons, and even a few great ones, but they've also missed the playoffs fourteen times since 1967. Of the Original Six teams, only Detroit (17 times!) has missed the playoffs more, but they've also won four Stanley Cups in that time so they get a pass.

DGB's article is a list of chapter titles for this book, many of which are unfair:

• "An unshakable loyalty...": the book isn't about how Leafs fans suck
• "The mysterious and spooky curse...": for all we know, half the book is dedicated to the Harold Ballard years.
• "Things we imagine Leafs fans would say...": again, the book isn't about the fans, it's about the team. And what makes you think these guys aren't Leafs fans? You can be a journalist and a Leafs fan. Just ask Damien Cox! OK, bad example.
• "Why 1927 is more recent than 1967...": DGB ignores the minor fact that the Senators didn't exist for fifty-eight of those years. The current Senators have only existed for 15 years, and they've gotten closer to the Cup than the Leafs have in 40.
• "Spilling into the streets...": It is pathetic when Leafs fans do it because of a first round win. When Calgary and Edmonton did it, it was when they won the Cup or in the recent case of Edmonton, made the finals after barely making the playoffs at all.

DGB also makes a point about the fact that this is a hockey book written by two NBA reporters. But I listen to Prime Time Sports (via podcast) every day, and Grange has been a guest on that show many times. He may be paid to cover the NBA, but he seems knowledgeable enough about other sports. Similarly, Jim Kelley has covered hockey his whole career, and is even a member of the Hockey Hall of Fame. But when the topic shifts to basketball, baseball, or football, Kelley can more than hold his own. I imagine sportswriters in general get into the business because they love sports, so the fact that they have been assigned a particular sport to write about doesn't mean they know nothing about other sports.

But even given all that, here's the main point: there's no indication that this is a history book. The cover of the book simply says "...why the Leafs STINK and how they can rise again". And the Leafs do stink. They've missed the playoffs three years running, and are very likely to miss them again this year. Barring some incredible moves by Burke in the off-season, they will not be much better next year.

Will I buy this book? Eh, probably not. But I'm not sufficiently homer enough to think that because it says negative things about my team, it must be a terrible book.

Big British Brother

What is it about the British lawmakers that they are so stupid when it comes to security? They already have more CCTV cameras in public areas than anywhere else in the world, and in the last few weeks, I've read all kinds of stories about how London Police have put up posters asking people to report those who:

• "study CCTV cameras"
• take pictures that "seem odd"
• don't give you details on their travel plans

It's now illegal to take photographs of British police officers. The London bobbies are probably the most photographed policemen in the world, and now taking pictures of them is a crime. (Note to self: tell Gail and the boys this before we go to London this summer.) I fail to see how photographs of police officers would be of any use to a terrorist. I don't know if this includes the Queen's guards at Buckingham Palace, but that might be a good thing to know.

Reporting people who take pictures of policemen or CCTV cameras is just silly, but asking people to report "suspicious people" is particularly disturbing. Like it or not, there are an awful lot of people who are particularly suspicious of Arabs or people who "look Muslim". Say I put my suitcase under my chair in the waiting area of an airport and then walk to the bathroom, leaving the suitcase under the chair. This is a stupid thing to do, but it likely wouldn't cause much concern. If an Arab man were to do it, there would be people screaming "bomb!" all over the place. Arabs (and other visible minorities) already have to deal with enough racism (blatant or otherwise) in their everyday lives, and these posters are just going to make things worse, while doing exactly nothing to prevent actual terrorist attacks. (Though the posters don't specifically say "be suspicious of Arabs", you know that many people will interpret them that way.) If I were of Arab or middle eastern descent and living in London, I'd be seriously considering moving somewhere more friendly to visible minorities. Like rural Texas.

And all the while, the UK government thinks they're doing their citizens a favour. This is nuts.

Porcupine Tree

I have recently been introduced to a progressive rock band from England called Porcupine Tree. Not only does the band have a cool name (very important), but they're talented musicians (also very important). I now have three of their albums, and I'm really enjoying them. I'll talk about the band itself in a minute, but I wanted to mention the way I discovered them, since it's rather unusual.

While writing some internal documentation for some code I had written, I used a tool called doxygen, which reads specially formatted comments in source code and creates documentation from it. Very nice tool, and while perusing the acknowledgements on the web site, I came across this line:

[Thanks to] the band Porcupine Tree for providing hours of great music to listen to while coding.

I was intrigued by the name of the band, but never thought much about it. A little while later, I was on amazon.ca and looked at my personal recommendations (after having bought some Rush and Dream Theater CDs), and there was a Porcupine Tree album. I immediately remembered the name from the doxygen guy, and since amazon said that the album was recommended because of my interest in Rush and Dream Theater, I was even more intrigued. After looking at some CD reviews, I took a $10 leap of faith. Without ever having heard any of the band's music, I downloaded their latest album, Fear of a Blank Planet, from puretracks.ca. After listening to that for a while, I went onto eBay and bought the two previous albums, Deadwing and In Absentia.

The boys in PT are big on eyes; of the three albums I have, two of them have covers that show someone with blank eyes – the Blank Planet one reminds me of the I Love It Loud video from Kiss, while the In Absentia one is so creepy that I don't even like looking at it.

While researching the band, I saw a comparison to Queensrÿche, who I'm a fan of (well, the older stuff anyway). But Steve Wilson's vocals and Geoff Tate's are nothing like one another, so it's kind of hard to hear the similarities. Musically, they're not that far off, but Porcupine Tree is a little more... well, "psychadelic" isn't the right word exactly, perhaps "ambient". Having said that, they remind me a little more of Tool or Dream Theater than Queensrÿche. They all have frequent time signature and key changes and some heavy guitar work, though PT isn't quite as heavy (well, usually – "The Creator Has A Mastertape" from In Absentia is pretty kick-ass). The vocals are quite different as well – PT's Wilson, Tool's Keenan, and DT's LaBrie can sing cleanly and quietly at times and louder at others, though LaBrie and particularly Keenan can also scream with the best of them (listen to Ticks & Leeches from Lateralus for a good example) while Wilson doesn't scream. However, PT and DT use a lot more acoustic guitar than Tool, and I'm pretty sure that neither Tool nor Dream Theater use a banjo on any of their recordings.

Amazon recommended PT to me because of both Rush and Dream Theater, but honestly, I don't see a lot of similarities to Rush. Other than the frequent time signature changes, the music is quite different.  They've been compared to Pink Floyd as well, though their music is much heavier.

Anyway, they have six other studio albums and a couple of live albums as well, so perhaps I'll peruse through the eBay listings again. I should probably take a break from eBay, though; I've bought 11 CDs (2 PT, one Nine Inch Nails, six Beatles, two Rammstein) through eBay in the last two months. I just love discovering new music.

Recommendations for you

I've only bought a couple of things on amazon.com, since I mainly use amazon.ca. When it gives me recommendations, they're based only on a few things and are therefore rather diverse:

• A book called Understanding IPv6
• a couple of CCNA guides (I had to look up what CCNA meant – it's some kind of networking certification)
• 101 Dalmations DVD
• Star Wars: The Clone Wars DVD (which I have, though amazon.com doesn't know this)
• Tool's Ænima CD (which I also have)
• Slayer's Reign in Blood CD

I imagine that there aren't many lists of anything that both Reign in Blood and 101 Dalmations are a part of.

Windows Live Writer

I recently upgraded my MSN Messenger to the latest version, and Microsoft was kind enough to ask me if I wanted to install a bunch of other crap applications with it! Well, it was kind of them to ask; not every company does (lookin' at you, Real Player). Anyway, one of the apps it asked about (and the only one I installed) was Windows Live Writer, which is essentially a WYSIWYG editor for blog postings. It has all your standard Word-like buttons for formatting text and adding images, lists (numbered and bullet), hyperlinks, tables, etc. as well as undo/redo. It also allows you to keep drafts, preview what the posting will look like when published, spell-check the article, and even add categories. It knows about the blog software you use so it can (presumably) tailor itself to what you're using. If you're using Wordpress rather than Blogger (which I use), some Wordpress-specific options may show up while Blogger-specific options would not be shown. Once you're done, you can even publish your article directly from Live Writer – just click a button, enter your password (if you haven't saved it), and you're done.

One of the coolest features is the preview pane. Live Writer will download your blog's template, and use it to generate the preview so that while you're writing your posting, you can see exactly what it will look like once published. Blogger has a preview option as well, but it sucks. I mean it really sucks. Really. It's just hopelessly broken. It does basic HTML formatting so that <em>italics</em> shows up as italics, but the font it uses is different from the one that the blog uses, tables and images aren't formatted the same way, the width of the text area is different, it just looks nothing like the final product. Google (which owns blogger) doesn't get much wrong with their software, but this is one area where they've really dropped the ball. Live Writer, on the other hand, shows the preview exactly as it will show up on the blog, complete with the sidebar, previous posts, dates, labels, links, the blog title, everything. I'm very impressed.

Before using Live Writer, I would write my blog entries in emacs using markdown format, then run it through a perl script I wrote that called markdown and did some other formatting and wrote the output to an html file. I could then preview the html file in the browser for formatting and when it was done, copy-and-paste the contents of the html file into the blogger "Create Post" page. Going from the text I was editing to the html was a two-step process – I would switch from emacs to a command shell and run fix <file> and then start <file>.html which would launch Firefox. From then on, I would save my edits, then go to the command shell and run fix again, then switch to Firefox and hit CTRL-R to refresh the page. This was not that big a deal, but the WYSIWYG thing is much easier and I love the accurate preview window.

I've used it so far to write a few blog entries (including this one) and I'm really starting to like it. The preview thing is awesome, it does spell-checking which neither emacs nor markdown do (after pasting the html on the blogger page, Firefox will do it, though I'd have to remember to actually check it before publishing), and there are plug-ins you can get to add other capabilities. For example, if you post lots of pictures or video to your blog, there are plug-ins to make those easier. One thing I don't particularly like is font support. If you choose a different font, it uses the <FONT> html tag to specify it. I don't like the font tag – I prefer using CSS – but I rarely change fonts anyway.

Interesting note: Over the past week, I have found a couple of interesting spelling suggestions for technical words from the spell checker:

• "Unix" for "unix"
• "Xbox" for "XBox"
• "VMware" for "VMWare"
• "Perl" for "perl"
• It doesn't know what "emacs" is (suggested "maces")

While testing the font thing out, I found another cool feature: if you do want to do something that the editor doesn't directly support (like <tt>fixed width text</tt>), you can just switch over to the Source window and enter the HTML directly. This also allows you to add other html stuff as well as custom styles, and even JavaScript (which actually runs in the preview window). Just for fun, I even tried the <blink> and <marquee> tags – though I truly believe that anyone using either of those should be shot – and marquee worked but blink did not. I don't care about that though, since I'll never use either of those on a blog entry. If I did, according to what I said before, I'd have to shoot myself. And I would.

Anyway, if you have a blog, and you use Windows (I kind of doubt that there will be Linux or Mac versions anytime soon), you may want to check this out. And by the way, in case you think this is a paid endorsement or that I'm posting this because I have friends at Microsoft or something, it's not and I don't. I did work at Microsoft for a four-month work term over seventeen years ago (holy crap, I'm old), and I know the guy who created Xbox Live (though he doesn't work for Microsoft anymore), and I listen to Scott Hanselman's podcast, but that's about the extent of my association with Microsoft. But if anyone at Microsoft wanted to pay me after the fact for writing such a glowing review, I'd gladly take an Xbox 360. Feel free to contact me for my address.

Telecommuting tools

I wrote earlier this week about my experiences telecommuting, and after reading a comment left on that posting, I wanted to write a little about the tools that I use to be more productive when working at home. But first, a bit of history.

Back when I started at Sybase in August of 1997, my friend and colleague Lisa suggested I ask the IT people for an extra monitor, keyboard, mouse, and power cable so that if I wanted to work from home, I'd just have to bring my desktop machine home and plug 'er in. I did this, and this made things pretty easy for the one day every few months that I worked at home. My desktop machine, running Windows NT 4.0, had a modem installed, and when I wanted to check my email, I had to unplug the phone on the desk and plug the cable into the modem, dial into Sybase, and then synchronize Lotus Notes. I only did this about once an hour because it was a pain. If I wanted to check some files out of source code control, I had to write down the name of the file in my notebook, manually reset the read-only bit on the file, and make a copy of the file in case I needed to revert it. Many times I forgot the copy and was unable to revert if I needed to. When I got to the office the next day, I'd have to go through the list of files that I wrote down and check each one out.

After a few years of this, management sent an email around asking if anyone would be interested in having a laptop rather than a desktop the next time that machines were refreshed. I responded with something like "Yesyesyesyesyesyes" several milliseconds after reading the email, and a few months later, I had an IBM laptop. This made things orders of magnitude better — I brought the extra monitor and stuff back to the office, and was then able to sit at the kitchen table when working. I had broadband internet at home by this point but no router, so I still had to use the modem to get email. Another couple of years later, I bought a wireless router for home, as well as a wireless PCMCIA card that I could plug into my laptop. I installed the Sybase VPN software and nirvana was achieved. I could then simply run Notes like I normally would to send and receive email, and I could also use our source code control software directly. I subsequently tired of Notes so I moved to Outlook and then a few years later, Thunderbird.

Back to the present. Here is a list of tools I use to make telecommuting easier:

• Firefox for web, Thunderbird for email, MSN Messenger for IM (this is true in the office as well as at home)
• A lot of people seem to use Skype for phone, but I don't really use the phone all that often. My regular phone works just fine. It does have a speakerphone, which makes things easier, especially for long conversations. Our old phone had a headset that worked pretty well too. That allowed me to walk around while talking on the phone which I always tend to do when not typing.
• Broadband internet (absolutely required!) and wireless network, though wired would work fine if the router was handy or there were drops available.
• VPN software is obviously a must. I won't say which VPN product Sybase uses for security reasons (security through obscurity, dontcha know!), but one of the "features" is that it automatically drops the VPN connection every 12 or 24 hours or something, even if the connection is in use, and with no way to cancel it. When the connection has been idle for a while, I can understand it but every now and again I'm in the middle of copying some large file to or from work and I get a popup saying something like "The VPN connection will be dropped in 2 minutes". Since there's no way to cancel it, the message may as well say "The VPN connection will be dropped in 2 minutes. I hope you're not actually using it, but if you are, well, it sucks to be you." I just have to hope the file copy finishes in that time, or that I can re-connect the VPN fast enough that the copy just continues. If not and the copy fails, I have to reconnect the VPN and start the copy all over again. My description makes it sound like a huge problem, but it's actually only bitten me once or twice in however-many years. It's just annoying that I have to reconnect, especially since the VPN software is buggy and sometimes crashes while connecting.
• Remote Desktop when connecting to Windows machines if possible. Some of our older (Windows 2000) test machines don't support this, so we use VNC for those. But Remote Desktop is preferable because it's faster and replicates the user experience more closely. If you maximize the Remote Desktop screen and the machine you're connected to isn't heavily loaded, you can almost forget that you're connected to a remote machine. This is not the case with VNC.
• When doing Unix stuff, I use VNC to connect to a Unix machine in the office and then use that to rlogin to other Unix machines. This works quite nicely, except that every now and again, I'll be in the middle of typing some stuff and a character will get repeated for no apparent reason. I'll be typing and something like cd /tmp/grrrrrrraeme will show up. Very irritating. I'm sure it's a problem with the VNC client software, because I occasionally see it in the process of repeating – like it thinks I'm holding the key down when I'm not – but when I hit that key again, it stops. I suspect this is because it got a KEYDOWN message but missed the corresponding KEYUP message. I have never seen this when VNC'ing into a Windows machine.
• I have a couple of VMware VM's set up on our VMware server so I can do stuff on a machine that's in our engineering subnet when I'm at home. Another VM has all the NetWare development stuff installed on it, though I rarely need that anymore.
• Apple iPod (5G, 80 GB) along with a Logitech Pure-Fi Express Plus dock for music. Another absolute must.

Nice Rock win!

The Rock won only their second home game of the year tonight, 16-10 over the Rochester Knighthawks. Watson played a great game in net, the D was solid, and most importantly, the boys played well for 60 minutes. There have been a number of games this year where they played great in the first half, or even the first three quarters, and then mailed in the rest and lost. Nice to see them play the whole game. Some other notes:

• Rochester's Mac Allen should have been sent to the penalty box just for that moustache.
• Pat O'Toole did not have his best game ever. His brother was sitting a couple of rows in front of us and didn't look too happy. He left at half-time and didn't come back.
• Note to Rock shooters: We're all really impressed with your accuracy, but hitting the goalie square in the middle of the chest does not help your team win games. In actual fact, you don't want to hit the goalie at all.
• The Rock scored two shorthanded goals on the same penalty.
• One fight, Bonterre vs. Campbell. The look on Campbell's face throughout the fight was "Oh crap, why the hell did I do this?" and with good reason – that Bonterre is one big fella. Only two punches were thrown in the fight, both by Bonterre, and it looked like he either broke or knocked out one of Campbell's teeth with one of them.
• Seriously though, that moustache. Damn.
• What's with Steve Dietrich leaving the field before the victory lap? I would have thought that was the first thing they told you when you became a Rock player.
• There was one goal called back after a review, but the review shouldn't have been necessary. The shooter's foot was definitely in the crease before the shot. Perhaps the ref was at a bad angle and couldn't see that, but I could see it quite clearly from my seat. The review only took a minute, so it must have been pretty obvious to the ref as well after watching the replay.

Let's not get too excited though, Toronto is now 4-7 and still in last place in the East. They have five games left to play, including one against league leaders Calgary and one against Boston who are second in the east. But the other three are all against teams with equal or worse records than the Rock (Edmonton, Philadelphia and San Jose), so we should be able to win at least two of those. The Rock beat Boston in OT a couple of weeks ago, so 3-2 or even 4-1 over the last 5 games is not out of the question. Rochester has played much better over the last few weeks than the first few (though that's not hard – over the first few weeks they looked terrible), and Philadelphia has Iannucci back now, so things, as always, will be tight in the east.

If the Rock want to see the playoffs, they will have to keep up their strong play (for four quarters per game) and keep their fate in their own hands, rather than playing badly and just hoping that someone else plays worse.

Inquiring minds want to know

A while ago, I posted a habit that programming has given me, and here's another. I don't think it's really a bad habit, as the original Stack Overflow question asked, but in a nutshell, I want to know algorithms for everything. The thing is, I'm not as interested in how software running on the space shuttle works, or running the machine that goes "bing" at the hospital. I'm interested in algorithms for relatively simple everyday things. I'd love to take a look at the source code for software running a car stereo, a bank machine, the fountains at the Bellagio in Vegas (I once saw a TV show on the guy who wrote that – very cool), or even a digital watch. One of the coolest projects I've ever worked on was a CD player application while I was at Microsoft in the fall of 1991. There was an app in Windows 3.x called Musicbox, which I suppose was the precursor to Windows Media Player. My job at Microsoft was to write a clone of that application. I never really figured out why they wanted me to do this – they had Musicbox which worked nicely – but I loved the project. I had buttons for play, stop, pause, fast-forward, rewind, and eject (which I labelled "spit" as in "spit out the CD" – it was funny when I was 22), a horizontal scroll bar that allowed you to seek to anywhere within a song, and other cool things like the ability to "bookmark" any part of a song (eg. "Awesome guitar solo!!!1!") and then immediately seek to it again later. MP3 didn't exist at the time, or at least I didn't know about it, so we were solely dealing with actual physical CDs.

Anyway... enough reminiscing, let's get back on topic.

I know how a GPS generally works – there are satellites in orbit that send out signals, and the GPS unit receives the signals from several satellites and somehow uses them to determine its exact position. I don't know exactly how, but I get the general idea. And I can guess how turn-by-turn navigation works – that's just graph theory. But what I want to know is how the information about roads and addresses and stuff is encoded in the graph. Sometimes you get a turn direction like "turn left at Dundas St." and other times it's "keep left onto Hwy 403". Somehow it knows that to get onto the 403, you stay to the left side of the road, rather than actually making a turn. How does it know that? How does it know that 222 Jarvis St. is between Dundas and Gerrard and not south of Queen?

All of the one-way streets and on- and off-ramps must be marked as such, as well as intersections where certain turns are not allowed, and other weird things like when there are two sets of lanes on a highway and you are in a set that doesn't have access to a particular exit. Every address must be encoded in there somehow indicating where on the street it is, including what side of the street and how far it is from the nearest cross street. How is that all encoded? I want the database schema.

Another example would be elevators. They're very simple to use, but how does the software controlling everything work? Say there's only one elevator which is at the ground floor. Someone on the 5th floor presses the "down" button, so you send the elevator up to 5. As they're getting in, someone on the 8th floor presses down, and then the person on 5 presses "2". Do you go down and drop off the person on 2 and then go up to 8? Probably. But while you're going down to 2, what if someone on 4 presses "up" – do you pick him up on the way back up to 8? What if he wants to go to 12 – do you take him up to 12 and then go back down to 8? That means that the guy at 4 got serviced before the guy at 8 although the guy at 8 arrived first. Are you trying to make things fair (i.e. first-come first-served), or reduce average waiting time, or reduce elevator movement, knowing that the occasional "customer" may have to wait a long time? Do people that have been waiting longer gradually become higher priority? Having multiple elevators servicing the same floors should reduce waiting times, but would make the algorithm more complicated. If there are three elevators and one is "out of service", does the software compensate for that by simply ignoring that elevator or does it change the algorithm somehow?

I'm sure some software developers dream of writing software to run in the most complex and important computer systems in the world – air traffic control systems, nuclear power plants, an automobile assembly plant. Me? I would love to write the software controlling a DVD player.

Roll up the rim to lose

I buy a tea and bagel from Tim Horton's on my way to work every day. For the last couple of weeks, the Roll up the Rim to Win contest has been going on, and thus far I have won exactly nothing. Last year I won a couple of coffees teas and a couple of donuts — nothing much, but it's always nice to win something. But does my lack of winning make me get angry and not go to Timmy's anymore? No, it makes me want to go more because I know the chances of winning are pretty decent and the fact that I haven't won yet makes me more likely to win the next time. Yes, I know that is absolutely not true, but it sometimes feels true.

So if I win, I want to go back to Timmy's to win again and if I lose, I want to go back to Timmy's to try again. They can't lose. It's brilliant.

Update: A friend of mine pointed out on facebook that she wins more often when she buys a large. Last time they ran this contest, I bought a large tea every day, and I won a few times. These days I buy a medium every day and haven't won at all. Coincidence? Hmmmm...

Telecommuting

I've worked as Sybase since August 1997, and have been a part-time telecommuter since January 2004. I already worked at home infrequently when the need arose (as did many others in our group), but at that time, my (old) car was around 275,000 km, and I wanted to reduce the mileage I was putting on it so that it would hopefully last a little longer. I asked my boss if I could regularly work at home one day a week (every Friday). He asked his boss who asked the President of the company (who to this day I have never met), and they all OK'ed it on a trial basis. Five years later, I'm still at home every Friday, and sometimes on other days as well. If there is a lot of snow in the forecast, I will generally work from home; in the past, I have had days where it took me two hours to get to work and the same to get home, and wasting that much time (and gas) seems really dumb if I can work at home and avoid it all. I've done this for a couple of years now, and I'm sure there have been days where the traffic would have been fine despite the snow, but one day a few weeks ago it was snowy but I didn't think it was that bad, so I figured I'd brave the weather. Stupid move. It took me a little over two hours to get to work, and then about an hour and a half to get home.

I've read a number of articles on telecommuting, and one of the pieces of advice I've seen the most often is that you should treat working at home as the same as going to work, meaning that you should sit down and work during your regular office hours, you should have a separate "office" space and not just sit at the kitchen table, things like that. I've even read about people who close the door to their "office" and force their family to either call or email if they need him, just as if he were at an external office. This seems a little extreme to me, but it does avoid persistent interruptions. I would love to have a dedicated place in the house where I could work more comfortably than the dining room. We do have an office upstairs, but the desk is so cluttered with stuff that there's no room for my laptop. If I were to clear off the desk and use that as my telecommuting "office", I think I'd have to invest in a new chair. Hmmmm.... I've thought about that idea in vague terms before but never really thought about it until now, and I'm starting to think that it's a really good idea.

Treating working at home like working in the office is particularly important if you telecommute 5 days a week, since you don't want to feel like you live in your office — you want a place that you can "walk out of" at 5:00 and feel like you're back home. For me, I only work at home one day a week most of the time, so I set my laptop up at the dining room table and sit there. Sometimes I used to sit at the kitchen table, since it's closer to the entertainment centre so I can plug my iPod in and listen to music while I work. I recently bought a speaker device for my iPod so I can listen in the dining room, so now I don't need to move. But generally, it's a normal working day. I get up at the same time, have a shower and get dressed, get the boys breakfast and make their lunches, just like any other day. It's just that when I'd normally kiss everyone goodbye and leave, I simply walk into the dining room and sit down.

It does take discipline to work at home. It'd be very easy for me to sit with my laptop in front of the TV all day, but I know that I'd get much less (read: nothing) done, so the TV never goes on. Surfing the web is harder to avoid since the browser is right there, but I'm getting pretty good at not sitting on Facebook or writing blog entries all day. Most of the incentive to not do this comes from my work ethic — I know that if I'm goofing around when I'm supposed to be working I'm essentially ripping off the company, and so I feel guilty. I do have to admit that some comes from the fact that working from home is a privilege that Sybase has given me. If they decide I'm not getting as much done when I work from home, they might decide that they don't want me to do this anymore, and I don't want to lose the privilege. It's something like: I want to be able to work from home and goof off, so when I work from home, I don't goof off in case they don't let me work at home.

One of the huge advantages of my job, from the point of view of telecommuting, is that from a work perspective, there's not much I can do in the office that I can't do from home. (Obviously teachers, policemen, and anyone who works in retail or deals face-to-face with customers doesn't have this luxury.) Copying large files over the network is much slower (100 Gb line vs. VPN over wireless G). I do a lot of network-related projects, and sometimes that doesn't work very well. As I've mentioned before, the product I work on is a mobile database called SQL Anywhere (SA), and the clients use UDP broadcasts for locating the server. When I'm at home, my machine is essentially on its own private LAN separate from the work one (VPN does stand for Virtual Private Network after all), so any broadcasting stuff doesn't work properly since UDP packets don't span subnets. I have a couple of VMWare images running on our VMWare server in the office, so whenever I need to do network stuff, I can simply remote desktop into one of those. I used to do a lot of work on the NetWare version of our product, and I can't do NetWare stuff at home either. But we don't support NetWare in the latest version of SA, and we get very few bug reports from previous versions (that's obviously because my code is robust and efficient, not because we only have a handful of customers using NetWare). I have my NetWare development environment set up on a VM now so I can do that from home anyway.

The obvious advantage to telecommuting is the lack of travel time and effort — not only does it reduce the time spent travelling (on Fridays I generally spend the extra two hours working), but it also reduces the gasoline used and the extra mileage on the car. On days where the traffic or driving conditions are bad, it also eliminates the likelihood of accidents, and lowers my general stress level as well. It's also very nice to be able to schedule things like dentists appointments and visits from service people (the furnace guy, the guy who will hopefully fix our dishwasher next week so I don't have to wash a thousand dishes every night, etc.) on Fridays and not have to take vacation days.

Other than work stuff I can't do from home, the main downsides to telecommuting are things like participation in meetings, whether scheduled or impromptu (Aside: "impromptu" is a really weird word), and socializing. Some things are just more difficult over email or IM.

From the company's point of view, there are only one real advantage: keeping employees happy (and therefore keeping employees). I do love my job, but if Sybase didn't allow me to work from home, I might have grown tired of the commute by now and left to find a job closer to home. In terms of job perks, it costs the company nothing, and is a display of trust on their part, further enhancing my overall job satisfaction.

I've written before about IvanAnywhere, the telepresence robot in our office controlled by my colleague Ivan Bowman, who lives in Nova Scotia. Ivan used to live and work in Waterloo, and now travels here a few times a year. But I'm curious how Ivan's working relationship with colleagues that he has never worked with "in person" differs from those with whom he has.

CD Review: Nine Inch Nails - The Slip

I downloaded the new Nine Inch Nails album a week or two ago (for free!). This was my introduction to NIN who are known as "industrial metal", but as with other labels, I'm not really sure what that means. Similarly, what does it mean for a band to say they are "alternative"? Alternative to what? R.E.M. was the quintessential alternative band for a while, then they sold zillions of CDs and had #1 hits and stuff, so are they still "alternative"? The best description I've heard for "alternative" was "Any band that I like that you've never heard of", which fits as well as any other description.

Anyway, back to industrial metal. Those readers familiar with NIN might be shaking their head, but I really have never heard any of their music, so I'm a NIN virgin, please be gentle. I have a couple of Rammstein albums (Feuer Frei! is such a great song), and a few Tool albums as well. NIN has a fair number of time signature changes, moreso than Rammstein though not as much as Tool, and both NIN and Rammstein have songs that have some electronica aspects while definitely having a basic metal sound. Both Rammstein and NIN have a couple of these type of upbeat almost-danceable songs (Discipline, Echoplex, Demon Seed), while the thought of dancing to a Tool song is just laughable.

One similarity among all three bands is that the vocals are frequently hard to decipher. I can safely say that I have no idea what any Tool or NIN songs are about — or Rammstein either for that matter, but that's because they sing in German. NIN and Tool also have songs with long instrumental stretches. With Tool, the instrumentals are mostly done with actual instruments, while the NIN songs 999,999, Lights In The Sky, Corona Radiata and The Four of Us Are Dying are mostly ambient sounds and minimal actual music. (Then again, the Tool songs Eon Blue Apocalypse and Faaip de Oiad (WTF?) are pretty much just noise too.)

One thing that differentiates NIN is the guitar sound. The guitar in NIN is much "fuzzier", while Tool and Rammstein use your standard distorted metal guitar. One album by The Tea Party, Transmission, has some songs that feature the same fuzzy distorted guitar sound as NIN, though I wouldn't generally call The Tea Party industrial or even metal. If you took Tool, swapped out the guitarist's distortion pedal for a more fuzzy one (or maybe added a few distortion pedals in series), mixed in some of the keyboard fills of Rammstein, and then somehow got the lead singer to cheer the fuck up a little, you'd get NIN.

To confirm what I said before about why free music is a good thing, I bought the older NIN album The Downward Spiral a few days ago, and I'm looking forward to receiving it this week. I just love listening to new music!

I just realized something else though — I bought The Downward Spiral used on eBay, so Trent won't actually be getting any money from me. But I can't confirm that the guy I bought it from didn't rip it and keep a copy on his computer or iPod. So why isn't Lars Ulrich fighting against the used CD industry?

Sure, but does it have Dolby Noise Reduction?

Gail got a new Walkman last weekend. She wants to do some more walking once the weather gets nicer, so she wanted a new MP3 player. We did some looking around and she decided on the Sony one. Note that the price on the Sony page is $119, but we found it at Future Shop for $79. Gail's main criteria were that it be small, have a display screen that showed you the song and artist name, and have the ability to use playlists. The playlist idea is so that she can set up a "warmup" playlist, consisting of songs of an appropriate speed for warming up, and then once she's warmed up and wants to pick up the pace, she can switch to another playlist consisting of faster songs.

The Walkman came with a CD of software, which I presumed was Sony's equivalent of iTunes. I installed it and it let me browse through the iTunes directory and select directories and files to copy to the Walkman. The docs say that non-MP3 files need to be converted to MP3 format first, but that their software will do that. Well, it seemed to want to convert MP3 files as well (to what, I don't know), and took forever to do the conversion and copy the files to the device. Then I read in some other part of the docs that you can use Windows Media Player (MP) to create playlists and transfer songs and such instead of the Sony software, so I gave that a try. Holy crap, what a difference. MP is miles faster (in terms of overall application performance), didn't do any MP3-to-MP3 "conversion", and lets you create playlists, which the Sony software doesn't do. Copying the files to the device was also very fast. MP doesn't handle podcasts (I don't think), but the Sony software does, so if you want to listen to podcasts, you might have to use the Sony software. But unless you need it, I wouldn't bother with the Sony software. It did say that it needs MP version 11, but that comes on the CD as well, so if you are not already running MP version 11, you'll need to upgrade. Vista comes with 11 so I didn't have to do anything.

As for the actual device itself, well, it ain't no iPod. While looking around at the store, Gail played with an iPod for a minute or two and said simply "Apple really does it right, don't they?" Yes, they do, but the iPods were double the price of the Walkman. Gail also liked the look of the Zune, but apparently Microsoft won't allow the store to use a display model, and we didn't want to buy it without giving it a try first, so the Zune was quickly dropped. Anyway, I'm very used to my iPod, so it took me a minute to realize that you have to actually press buttons rather than just drag your finger around. But I got used to it pretty quickly, and didn't have to keep looking down at the buttons to figure out what to do. They say that a good interface is one that "disappears" while you're using it, so this would have to qualify. The menus and such are similar to the iPod, so you can choose what to listen to based on artist, album, song, and genre (I think), or you can play from a playlist. It seems to have shuffle capability as well.

Now, we haven't really used the Walkman yet, just played with it a bit and started to get things configured, so time will tell. Maybe after using it for a week, Gail will hate it and we'll take it back. Or she'll love it and wonder how she ever lived without it (like I do with my iPod), but more likely, it'll just be fine. Gail's not one to fall in love with technology (unlike her husband and his goddamned beloved iPod), so as long as it does the job that it's supposed to do, everything will be peachy.

Aside: The image above is one that I found online with a google search, but I chose it because it happens to be the same model as the second Walkman I had in high school. That model was very cool because it had MEGA BASS. It also had Auto Reverse, which was also a very cool feature, but not as cool as MEGA BASS because the first Walkman I had also had auto reverse. MEGA BASS was new. Oddly, my boss has a cassette Walkman in his office, which is the same model as my first Walkman. He does have an iPod which he uses when walking to and from work, so I have no idea what he uses the cassette player for.

The World Baseball Whatever

The second World Baseball Classic is in progress and once again, I just cannot get into it. The idea is great; as a baseball fan, any way to promote baseball around the world is fine by me. But until I looked up the wikipedia entry, I couldn't remember who won the last one. Off the top of my head, I can't name more than three members of the Canadian team (Jason Bay and Justin Morneau because they're awesome and Stubby Clapp because I can't imagine anyone willingly going by the name "Stubby").

I did watch a bit of a game earlier today while folding laundry, but I didn't finish watching it, and did not later feel compelled to find out the final score like I did watching women's softball during the Olympics. Now maybe that's because the game I happened to be watching was the Cubans wiping out the South Africans 7-0 in the 5th; if the game had been close, I might have been more interested. Canada plays Italy tomorrow night with the winner advancing to the next round and the loser going home, so I may check that game out, but I wouldn't be too surprised if it slips my mind.

It would be different if this was a competition featuring the best baseball players in the world, but it's not. It's a competition featuring the best baseball players in the world who aren't injured, weren't injured last year, didn't have off-season surgery, whose teams allowed them to play, and who give a damn about this tournament. When players like Halladay, Pujols, Beltre, Santana, Papelbon, Lincecum, and Dempster are all skipping it so that they don't miss spring training, you can tell the level of interest in this tournament. I don't remember many American basketball players or Canadian hockey players who have passed on the Olympics for any reason other than they were physically unable to play.

It's pretty simple, really — if the best players in the game don't care about the tournament, why should I?

Next morning update: I totally forgot about this game last night. Turns out that this might have been a good idea since Canada lost.

Mid-season NLL report

We're halfway through the NLL season, and it's time to look over my pre-season predictions and celebrate the fact that I was 100% bang-on with all of my predictions. Well, almost.

East Division

	Predicted	Actual
1	Buffalo	Buffalo
2	Philadelphia	Boston
3	New York	New York
4	Toronto	Philadelphia
5	Rochester	Rochester
6	Boston	Toronto

West Division

	Predicted	Actual
1	Minnesota	Calgary
2	Calgary	Portland
3	Colorado	Colorado
4	San Jose	Minnesota
5	Portland	San Jose
6	Edmonton	Edmonton

OK, not almost. I got a few right, but in some cases, I'm not even close. In the East, it's hard to get Buffalo wrong, I had New York contending, and Rochester near the bottom, but that's about it. Philly didn't weather the loss of Iannucci very well at all, and my fairly dire prediction for Toronto turned out to be really optimistic. I didn't have high hopes for Boston, but they've turned out to be much stronger than I thought. I did say in my original prediction that they would be stronger than your average expansion team, but for some reason that didn't get reflected in how I viewed the standings.

In the West, Minnesota hasn't been the powerhouse I thought they might be, and Portland is not sucking. I got Calgary and Colorado pretty much right, and Edmonton is no surprise.

But in the East, if you swap Boston and Philadelphia in the standings, you get something very close to my prediction. In the West, if you swap Minnesota and Portland, same thing.

Note for the record that I made end-of-season predictions, not mid-season. There's lots of lacrosse still to be played.

What if we give it away?

Hot on the heels of Harvey Danger making their album available for free download (which I've blogged about a couple of times), Nine Inch Nails have done the same thing. OK, well maybe not "hot on the heels", since Harvey Danger did it over three years ago, but this is another example of a band (or person actually, since NIN is Trent Reznor) that actually gets it when it comes to downloading music.

A lot of people and bands (Lars Ulrich of Metallica comes screaming to mind here) seem to think that downloading music is the scourge of society, and allows people to essentially pull money from their pockets. What they have to consider is that many of the people downloading their music illegally wouldn't have bought it in the first place. Would I have gone out and bought a Harvey Danger CD? No, because I'd never heard of the band, but I'm willing to download it and listen for free. If it sucks, I've lost nothing. But if I like it, I'm more likely to go back and buy it or some previous album (both of which I did for Harvey Danger), which is money that the band made that they wouldn't have otherwise.

Are there people who will download music instead of buying it? Absolutely. Back in high school, my friends and I would all negotiate who was going to buy the latest album from Kim Mitchell or Van Halen or whoever, and everyone else would give that person a blank tape and he'd tape it for the rest of us. So yes, we were pirating music. But at the time, I was a high school kid and didn't have much money anyway, so I was unlikely to buy 90% of the albums I taped, meaning that nobody was losing money by me doing this. On the contrary — while I may not have bought Akimbo Alogo at the time, I did listen to it and became a Kim Mitchell fan. Years later I did buy Akimbo Alogo on CD, along with a couple of other Kim Mitchell albums as well as all of the Max Webster albums, so Kim did end up benefitting from my piracy.

Similarly, I've been interested in hearing NIN for a while, but since I'd never actually heard any of their music, I was hesitant to just go out and buy something. Downloading the album gives me the chance to hear it and decide if I like it, and so far I do. So perhaps I'll buy some of their older stuff — once I do that, NIN will profit from my downloading their album. If they never released it for download, I wouldn't have bought it, and they'd have made nothing from me. Thus far, since I haven't bought any NIN stuff, they still haven't made anything from me, but now the potential's there.

Let me be clear: I may have done it in the past and even tried to justify it above, but I'm not advocating piracy, so chill out, Lars. I do have a handful of albums that I downloaded illegally a couple of years ago (none of which are Metallica, so chill out, Lars), and I feel a little guilty every time I listen to them. But I have bought copies of several of the ones I listen to often (I just bid on a copy of Abbey Road and two Rammstein CDs on eBay), and I've also deleted some that I don't. I haven't downloaded any music or videos (other than the odd TV show that I missed, none of which feature Metallica, so chill... OK, that joke's getting old) in a couple of years. I'm really not talking about stealing music, I'm talking more about the bands that choose to make their music available for download, most of which are indie bands like Harvey Danger. But it's nice to see some big-name bands like NIN doing the same thing.

Steve Gibson needs a blog

Steve Gibson needs a blog. Seriously. I've been listening to his Security Now (SN) podcast for over a year, and I do enjoy it, but it seems to be getting longer and longer every week, mainly because of things that Steve and Leo start talking about that are not security-related.

I'm in the middle of episode 184 now, which is a Q&A episode. This is where Steve picks twelve questions from listeners and answers them. This episode is about an hour and fifty seven minutes long. The first question isn't even begun until forty two minutes into the podcast. Some of the topics discussed before the first question:

• a minute of advertising for the TWiT network.
• seven minutes of introduction and talking about Steve's appearance on another TWiT podcast next week regarding historical computers (PDP-8, PDP-11, and such)
• two minute commercial
• ten minutes of recent security news. He mentioned the Pirate Bay trial as well as an authentication problem he had with Paypal. Definitely security-relevant.
• seven minutes of talking about a couple of computer utilities he uses, his favourite sci-fi TV shows (Fringe is his current favourite, if you're wondering), more on historical computers, and how he maps his Caps Lock key to Ctrl because Caps Lock is not very useful. Can't disagree there.
• a seven-minute Spinrite "testimonial", i.e. commercial. He does one of these every week, and I'm sure this is one of the reasons he does SN — it lets him plug his software. Again, no big deal since I skip it anyway, other than the fact that it was very long.
• four minutes on how Steve's computer plays a "Yabba Dabba Doo!" sound whenever someone buys a copy of Spinrite, and how the number of times he hears this sound is inexplicably higher during the recording of SN than at other times. The only explanation that he and Leo have come up with is that some people like to buy Spinrite while SN is being recorded so that they can hear the sound bite for their purchase (you can listen to the podcast being recorded live at twit.tv on Thursday afternoons). This was kind of funny, actually.
• two minute commercial
• two more minutes on the Yabba Dabba Doo thing and other sound bites that Steve's computers play

The twelve questions take an hour and 15 minutes or so to read and answer, with at least one more two-minute commercial in there. This seems pretty long too, but this is the actual meat of the show, so I can't complain too much about that. There are some questions that could be answered a little more succinctly though.

Leo starts to read the first question at the 42:00 mark. Some of that 42 minutes was commercials, evil but necessary. Twelve minutes seems a little long though — the Spinrite commercial testimonial should be kept to three minutes. The security news section is part of why I listen to this podcast, so that's definitely fine. I get that Steve and Leo have interests outside of security, but there's twenty minutes of just general banter. If you guys want to shoot the shit, do it before recording.

If Steve had a blog, he could ramble on all he wanted about Fringe and sci-fi in general, and old computers, and his Yabba Dabba Doo sound bite, and his network setup, and his Kindle, and his favourite kind of coffee that he drinks seven times a day, and the fact that he gets his first coffee at Starbucks at 5:30 in the morning, and how he writes everything in assembly language, and so on. He could spend thirty seconds per episode plugging his blog and spend the rest of the podcast on actual security stuff. stevegibson.com seems to be taken by an organic farm in Texas, but perhaps he could pull a Dvorak and get gibson dot org slash blog.

Update: For some reason, this particular article has gotten a lot of comment spam, so I have had to disable comments on it. Apologies for the inconvenience.

Sushi IS for dummies?

We were in a bookstore yesterday, when I saw a book in the ubiquitous "... for Dummies" series called "Sushi for Dummies". Ryan saw it and said that a friend of his liked sushi. I asked "You know who else likes sushi?", expecting him to say "who?", at which point I'd say "me", but his response made me laugh:

"Dummies, I suppose."

Technical Debt

Jeff Attwood wrote an article on his blog Coding Horror yesterday all about paying down your technical debt. This is when you do something "the quick and dirty way", which then costs you "interest" in the future in terms of bug fixes, workarounds when new functionality is needed, and just extra time for developers unfamiliar with the code to understand why something was done the way it was. There are certainly times in every developer's life when you have a choice between doing something "the right way", which might take weeks to design and implement properly, or you could do it the easy way, which gets the job done for now, but may have consequences later. If you're under a tight deadline, often the easy way wins out — that's your debt.

People often complain about Microsoft Windows being bloated, and that's largely because of technical debt that they can't easily pay off. When they released Windows NT in 1993, they made sure that all existing Windows and DOS programs would still run. That decision saved them — who's going to upgrade to a brand new OS when there are no programs and drivers for it, and none of your existing stuff will work? — but they incurred a huge debt because of it. Backwards compatibility has always been a huge issue for Microsoft — it's only recently (2007) that they released an OS (Vista) that won't run 16-bit DOS software from the 80's. I cannot imagine how much of the Windows source code is dedicated to running legacy software.

I love this "technical debt" metaphor, as we've gone through it a couple of times on our mobile database product, SQL Anywhere, most notably a few years ago on SQL Anywhere version 10.

One of the advantages of SQL Anywhere is the way we save data in the database file. We do it in such a way that a database created on any supported platform can be copied and used on any other supported platform. Also, if you create your database with one version of our product, you can continue to use it when we release updates for that version, or even completely new versions. Version 9.0.2 of our server, released in 2005, can still run databases created with Watcom SQL 3.2, released in 1992. I remember my time as an Oracle DBA - every time we upgraded Oracle, we had to "fix" the database, and by "fix" I mean we had to rebuild it or upgrade it or something. I don't remember what we had to do, but we had to do something. We also had Oracle on our test server, which was a different platform than the production server, which means that we couldn't just copy the production database to our debug server for testing or debugging purposes, which was quite a pain.

Anyway, while this was a very convenient feature, we did accrue some "technical debt". This is not quite the same as described above, in that we never took the "quick and dirty way", but we still had to have code in the server to support features that had been removed from the product and very old bugs that had long been fixed. After six major versions and thirteen years, there was a lot of these. After much discussion, we decided to take the big plunge with the 10.0 release (known internally as "Jasper" — the last few releases have all had code names from ski resorts, "Aspen", "Vail", "Banff", "Panorama", and the next one is "Innsbruck"), since we were adding a ton of other new functionality with that release. The decision: version 10 servers would not run databases created with version 9 or earlier servers. Everyone would have to do a full unload of all their data and reload it into a new database when upgrading to version 10, and they'd have to do this for all their databases. This would allow us to remove thousands of lines of code from the product, making it smaller, and since we have far less cases of "what capabilities does this database have?", the code can be more efficient. As a simple example, we now know every database that the server can run supports strong encryption, checksums, clustered indexes, and compressed strings, among others, so we don't need to check for those capabilities before using them. There are a lot more assumptions we can make about the layout of the database that makes the code simpler, smaller, and more efficient. We can also add new features that might have clashed with old databases. We knew that the rebuild itself might be inconvenient, and upgrading to version 10 wouldn't be nearly as seamless as previous upgrades, but we also knew that once the initial pain of the rebuild was over with, life would be much better for everyone. We even put a lot of work into streamlining the rebuild process so that it was as fast and simple as possible.

As you can imagine, there was some resistance to this, and I'm sure product management had to handle more than one call from a customer asking "I have to do what with my multi-terabyte database?", but to their credit, they stuck to their guns and told the customers that yes, we know it's inconvenient, but it's really for the best, and you'll appreciate it once the rebuild is done. Or perhaps they blamed it on us, telling the customers "We know it's a pain, but engineering won't budge. They're determined to do this." Either way, it happened, and we did get some more bug reports because of problems with the rebuilds, but for the most part, things went pretty well. That pain paid off the technical debt that we'd accumulated over the previous decade.

Of course, we've since released version 11, which added new stuff to the database file, and we're working on version 12 which adds even more, so now some of those "if the database file has this capability, then do something, otherwise do something else" conditions are creeping back into the product. So far, there aren't a ton of them, so our current interest payments are pretty low, but perhaps in five or six more versions we'll have accumulated enough technical debt that we'll have to bite the bullet and pay it off again.
