Steam UI Update Beta Drops IE Rendering For WebKit 244

Posted by Soulskill from the what-a-coincidence-with-battle.net-in-beta-too dept.
Citing massive growth in their user base ("25 million users, 1000+ games, 12 billion player minutes per month, and 75 billion Steam client minutes per month"), Valve unveiled a revamped UI for Steam on Tuesday, opening the beta test to anyone who wants to try it out. There are many changes, and an increased focus on social features: "Right from within your own game Library, you can now track which of your friends plays each game or invite them to play one with you. Before you've even bought a game, knowing whether your friends play it is one of the most useful pieces of information to have. So on the store homepage, there's a new listing of what your friends have bought or played lately." Tracking games and achievements have both gotten simpler, and Valve has dropped the Internet Explorer rendering engine in favor of WebKit. An enterprising user also found files that may indicate the existence of an OS X Steam client.

Quake 3 For Android 137

Posted by Soulskill from the can-i-get-a-hell-yeah dept.
An anonymous reader writes "Over the last two months I ported Quake 3 to Android as a hobby project. It only took a few days to get the game working. More time was spent on tweaking the game experience. Right now the game runs at 25fps on a Motorola Milestone/Droid. 'Normally when you compile C/C++ code using the Android NDK, the compiler targets a generic ARMv5 CPU which uses software floating-point. Without any optimizations and audio Quake 3 runs at 22fps. Since Quake 3 uses a lot of floating-point calculations, I tried a better C-compiler (GCC 4.4.0 from Android GIT) which supports modern CPUs and Neon SIMD instructions. Quake 3 optimized for Cortex-A8 with Neon is about 15% faster without audio and 35% with audio compared to the generic ARMv5 build. Most likely the performance improvement compared to the ARMv5 build is not that big because the system libraries of the Milestone have been compiled with FPU support, so sin/cos/log/.. take advantage of the FPU.''

UI Customization and Capital Ships In Jumpgate Evolution 41

Posted by Soulskill from the make-mine-look-like-an-x-wing dept.
ZAM got a chance to speak with NetDevil's Scott Brown at the recent LOGIN 2009 conference about various aspects of upcoming space MMO Jumpgate Evolution. He mentioned that massive ships will be limited in scope and role to begin with, but may expand and evolve as they figure out what users like. He also made some interesting comments about UI customization: "We built it with the goal of letting people mod the UI. There's still a little bit more work to do that, so I don't know if it'll be ready at launch, but all of our UI is built in Flash. This is with the idea that anybody can build something with Flash and put it in the game. Now, there are problems, for example, if you do certain things in Flash that might cause the game to perform really slowly. We've still got to figure out how to educate people or how we verify this so that you don't make a mod that I download and my game experience is destroyed. We want it to be easier than that. I think that there will be some work to do, but the goal is that, eventually, people will be able to, using Flash, make their own UI."

Terminator Salvation Opens Well, Scientists Not Impressed 344

Posted by Soulskill from the come-with-me-if-you-want-to-groove-baby dept.
destinyland writes "A science magazine asks an MIT professor, roboticists, artificial intelligence workers, and science fiction authors about the possibility of an uprising of machines. Answers range from 'of course it's possible' to 'why would an intelligent network waste resources on personal combat?' An engineering professor points out that bipedal robots 'are largely impractical,' and Vernor Vinge says a greater threat to humanity is good old-fashioned nuclear annihilation. But one roboticist says it's inevitable robots will eventually be used in warfare, while another warns of robots in the hands of criminals, cults, and other 'non-state actors.' 'What we should fear in the foreseeable future is not unethical robots, but unethical roboticists.'" The new movie got off to a good start, drawing $13.4 million in its first day. I found it reasonably entertaining; pretty much what I'd expect from a Terminator movie. If nothing else, I learned that being able to crash helicopters and survive being thrown into the occasional wall are the two most valuable skills to have during a robot uprising. What did you think?

Judge Rules Fox Has Copyright Claim To Watchmen 262

Posted by timothy from the there-are-ways-of-telling dept.
fermion writes "According to the NYT, a judge has decided that Fox owns the copyright to Watchmen, not Warner. Is this an example of copyright law becoming so complex that companies can abuse the court system to prevent competition, or just extreme incompetence by Warner? In the current business environment, either explanation is believable. Yet it is unbelievable that seasoned producers would spend hundreds of millions of dollars to create a movie that they can't even release. It seems the judge didn't want to bring this to a jury, and maybe daring Warner to appeal, or Fox to settle." The article says that Fox acquired movie rights to the Watchmen story in the late 1980s, but budget disputes and personnel changes have muddied the waters; Wikipedia has a bit more on the "development hell" which has plagued the film project.

Hydrogen peroxide powered rocket packs fly for around 30 seconds, because they have a specific impulse of around 125, meaning that one pound of propellant can make 125 pound-seconds of thrust, meaning that it takes about two pounds of propellant for every second you are in the air. Mass ratios are low for anything strapped to a human, so the exponential nature of the rocket equation can be safely ignored.

A pretty hot (both literally and figuratively) bipropellant rocket could manage about twice the specific impulse, and you could carry somewhat heavier tanks, but two minutes of flight on a rocket pack is probably about the upper limit with conventional propellants.

However, an actual jet pack that used atmospheric oxygen could have an Isp ten times higher, allowing theoretical flights of fifteen minutes or so. Here, it really is a matter of technical development, since jet engines have thrust to weight ratios too low to make it practical. There is movement on this technical front, but it will still take a while.

There are several "provably secure" computer systems. As in you can demonstrate they fulfil certain mathematical constraints and those constraints are absolute. Then you have to write the code and prove the code, then you have to hope the prover is correct and the hardwareis correct. Nothing is 100%.

As to the randomisation stuff - yes I've got examples, and we've hit the same thing in Linux with randomisation. You get cases where memory scribbles cause a problem only if the layout happens to be a specific variant (especially with stack randomisation). From "either it dies or it works" you get "1 in 10,000 times xyz app blows up". That does make debugging much much harder. Of course a good reply to that is "so improve the debugging tools".
