$2 Million NASA Power Beaming Challenge Heating Up

Posted by timothy on from the when-moving-target-is-not-figurative dept.

carstene writes "Qualification rounds for the NASA Centennial Challenge Power beaming contest are underway at the Dryden Flight Research Center. The contest uses a scale model of a space elevator as a race track. Entrants must build a robot to climb a cable, suspended by helicopter, 1 km into the sky without any on board energy storage. The teams are using high power laser beams to transmit power from ground stations to photovoltaic arrays on the robots. If a team can accomplish this at 5 meters per second average speed then they could win up to 2 million dollars. One day this technology could be used to power rovers in shadowed areas of the moon or to recharge electric UAV's in-flight or even a space elevator in the far future. A blog of the event can be found here. Full disclosure: I'm a member of the LaserMotive team that you can follow on twitter, or or via blog."

    I have to say that Firefox is getting a lot worse lately. The user experience is in serious need of improvement and development is the pits. I installed the latest "big deal" Firefox update on June 30th. (For some reason they skipped a full four secondary updates, but whatever.) Upon restarting, which took several minutes, I began using Firefox 3.5.

    At first, Firefox seemed strangely familiar. I thought they had changed very little unnecessarily until I visited the Acid3 test. Lo and behold, I was still using Firefox 3.0.0.11. What the fuck? I manually invoked Check for Updates and repeated my first attempt only to find, upon restarting, the same thing.

    Finally in desperation I downloaded the installer manually from Mozilla. The install ran surprisingly quickly and, after a few minutes, I was launched with the new version. I had to check, though, because again I thought it looked like very little had changed.

    In fact, did Mozilla bother changing anything beside the JavaScript? The new SpiderMonkey is great and all, but they could have at least made it look like they were working on something else. When the most noticeable improvement is the "Know Your Rights" button (which everyone ignores) one really starts to wonder what the fuss was all about.

    Well, after the three tries it took to upgrade, I found my profile wouldn't migrate. This was a mess, but I was able to eventually retrieve my bookmarks from a long, arcane file path in a hidden directory. But then upon visiting my bookmarked sites I found that almost none of my add-ons are compatible with it. Therefore my browser is almost entirely functionless.

    The bookmark tool itself could use a polishing. It's a mess and has been since version 1.0. If a browser is meant to render and organize content, Firefox surely falls down in this area. Why does it take me several minutes to slosh through the GUI just to make a new folder and alphabetize some bookmarks in it? Not to mention the damned Bookmarks toolbar, which takes up too much damn space and can't be turned off.

    And speaking of the GUI, it's slow as Hell! Get rid of the proprietary XUL and just hardcode the damned interface already!

    I also have to mention memory use. On my system, Firefox was swallowing an incredible 400 MB with only a simple HTML 5 page open. 400 MB?! I blame this on the Firefox team's use of C++, where memory management is about as easy as herding cats. Likewise Firefox is a slow, bloated nightmare. (For a contrast, there's Safari, which is written in Objective C and is very small and efficient.)

    Most of the time I have heavy JavaScript sites open. I shudder to think how much Firefox eats then, and I'll be sure to check in the future. No wonder my system tends to slow down when I've left Firefox open for days on end with dynamically updating pages and RSS feeds. Clearly, Firefox leaks memory like a cracked sieve in a waterfall.

    With Firefox smelling more and more like crapware, I started to dig a little, first on Wikipedia and then on the Mozilla Development Forums. It turns out that my observations are part of a larger pattern of Firefox quality issues and development customs. The Mozilla developers are a bunch of arrogant, abusive shitheads.

    For starters, they're still running all tabs in the same process. This is something IE7 and Safari 3 have had right for years. S
