• Metrics in software and physics

    A Horrible experiment Every so often, somebody points out how bad of a metric code coverage is. And of course, on its own, it doesn’t tell you much: after all, it’s a single number. How could it possibly reflect all the subtlety (or lack thereof) of your designs and of your testing artillery? Of course, within all the various *DD approaches, some better than others enable you to know whether or not your code conforms to its requirements, but I thought I’d take a moment to reflect on the general idea of a software metric and how it relates to the mothers of all metrics: physical ones, cause you know, I used to be a scientist. Proof: the lab coat on the picture.

  • Why Guitar Hero is dead to me

    (c) Bertrand Le Roy 2007 I bought the new Guitar Hero 5 because I needed a new fake plastic guitar and Activision’s guitars are the best that are not outrageously expensive. The Rock Band guitars I just can’t stand. So as I was going to buy a guitar from them, I thought I might as well get a (couple of) cheap game(s) with it.

  • The symmetrical universe

    (c) Bertrand Le Roy 2005 Warning: this post is devoid of contents.

    During one of the very first classes of my Bachelor of Science in Physics, I got struck with a particular piece of information that sounded like a revelation to me:

    If a problem exhibits a certain symmetry, the solutions to this problem do not necessarily exhibit that same symmetry, but the set of solutions always does.

  • The French are so lazy...

    The economist has a piece about how much American kids study (http://www.economist.com/world/unitedstates/displayStory.cfm?story_id=13825184&source=most_recommended) that starts with the requisite clichés about the lazy French.

    Did you know that the French are the fifth most productive people of the OCDE, before the US and way before Japan?

    It's true that the American work on average 11% more than the French but did you know that on average the French work more (and better) than the German?

    Interestingly, there seems to be an inverse correlation between hours worked and productivity: the less you work, the better you work.

  • The PlayStation’s Flower power

    flower Yesterday, I bought Flower for the PS3 and played it through in one sitting (the game is really short but still, couldn’t get my hands off the controller once I started).

  • We need Rock Band / Guitar Hero song compatibility

    In this post, the Penny Arcade guys make the point that beyond instrument capability, what we really need is song compatibility between the two. Beyond the licensing nightmare that would probably represent for both games publishers, this resonated really well for me. Here’s why and why it makes perfectly good business sense below the apparent “yeah, right, you wish” appearances.

  • You're not being reasonable

    Ever since it came out, it seems like Wii Play has been somewhere on top of sales charts and even managed to be the #2 top-seller of 2007 in the US. Let's be clear about this: even if it looks like a good deal, being only $10 above the price of a standalone Wiimote, it really isn't. It would be a good deal *if* Wii Play itself was worth $10, which it isn't by a very large margin (i.e. at least $10). As a matter of facts, if you gave me $10 to play this thing (which I refuse to call a game), I would decline. And I want the fifteen minutes I spent trying to play it back.
