I wrote a web site/spider to do this for the whole network at uni. It was beautiful C++ all the way. After I left some silly CS people rewrote it in Python/PHP (ugh) here: http://code.google.com/p/trufflepig/
It doesn't convert it to a 'different beast entirely'. It's still bytecode, and slower than native code.
new/delete is still much faster than garbage collection, and doesn't freeze the UI like Android's GC does.
Check out this paper, they found that java with manual free's performs much much better than GC java, especially when memory is limited (as in phones):
And more to the point, what about garbage collection? Every time the garbage collector kicks in the UI freezes for a short time. You really don't want this in a game (or at all really). In fact can anyone name any popular games written in Java? As far as I know they are nearly all C/C++.
Luckily you can write OpenGL Android games in C++ using the NDK.
"I think there is a strong possibility of extraterrestrial life based on a passage in the Bible. The Lord talks about gathering His creation from the ends of the Universe."
This idea is as old as the hills (or at least mobile phones). It will never really work well though because who wants to waste their phones battery on relaying other people's data?
Rubbish. kph is a well-known abbreviation for kilometres per hour. It is pretty unambiguous because a) it is really widely used and understood, b) it has no other sensible meaning, c) using 'p' for 'per' isn't in the SI system anyway so you aren't really abusing anything.
When I hear morons talk about muscle memory in Excel I know they don't understand what an advanced user is. Did ANY advanced user actually grab the mouse and click on a menu option rather than using one of the numerous keyboard shortcuts?
Are you saying that the way you access a feature (GUI vs keyboard shortcuts) determines how good you are at using Excel? What complete and utter codswallop.
This is clearly a very intelligent person whose skills are of immense value.
From Wikipedia: McKinnon claimed that he was able to get into the military's networks simply by using a Perl script that searched for blank passwords; in other words his report suggests that there were computers on these networks with the default passwords active.
Note that this is never ever reported in news articles. It is always that he 'hacked into' the computers. I think most people would agree that trying blank passwords doesn't really count as hacking, and most people have probably done it at one point in their lives. It is completely ridiculous that he could be extradited over this.
"But yeah, combining Street View with Photosynth is an obvious thing that comes to mind."
Been done. I think I saw it in a demo video for an 'augmented reality' phone navigation program, possibly for android. The trouble is you only have two or three views of each point. What *would* be cool is to record a video panorama as you travel round a city. That would be better because
a) You have many more views, and b) You know one frame is taken near the previous and next frames, so you can use optical flow algorithms and probably get more points in the point cloud.
I totally agree, but it seems the linux devs don't want to have to maintain a stable driver ABI. I think that's a pretty silly position to take; hopefully they'll change their minds at some point.
OSS made it impossible to play more than one stream at once on a lot of hardware.
That was OSS 3. OSS 4 apparently allows you to do this on all hardware and is apparently much nicer than ALSA. It's also open source again. I read a good article about this situation a while ago but can't find it now.
Wrong again. The uncertainty principle is very badly named because it applies even if you know *everything* about the electrons and are uncertain about nothing.
The problem is like trying to find the position and frequency of a wave packet. Both position and frequency are kind of macro quantities and it wouldn't make sense to fix them both at the same time. For example a wave with only one frequency must be the same everywhere and hence has no position. Conversely a delta function has an infinitely wide spectrum.
Furthermore this is the first carbon composite airliner ever made. It's obviously going to have more problems than another aluminium plane. For example one of the problems with composites is that it is really easy to get subsurface delaminations that are very hard to detect. These problems are going to take time to solve.
I read the court documents for the trial a while ago. There were two issues:
1. They quoted the statistics assuming the deaths were independent (i.e. the squared the probability of one SIDS death). The error of this was pointed out. 2. No one mentioned the prosecutors fallacy.
In the end the jury were won over by an argument along the lines of: "Ignore the statistics. You *know* it's really unlikely that these were two SIDS deaths.".
You buy a contract separately from the phone. You *do* realise that the contract price you pay (e.g. £35/mo) *with* the phone is simply the normal SIM-only contract (£17/mo with data on O2) plus some money to cover the cost of the phone?
Like the original poster I am amazed how many people thing these phones really cost $99 or that the carriers 'subsidize' them.

Android doesn't use incremental garbage collection. Or JIT for that matter.
And more to the point, what about garbage collection? Every time the garbage collector kicks in the UI freezes for a short time. You really don't want this in a game (or at all really). In fact can anyone name any popular games written in Java? As far as I know they are nearly all C/C++.

I agree. No mention of a paper, or any corroboration. Is this guy ( http://setiathome.berkeley.edu/view_profile.php?userid=4422 ) claiming that he's discovered it? By the way, comedy quote from that page:
"I think there is a strong possibility of extraterrestrial life based on a passage in the Bible. The Lord talks about gathering His creation from the ends of the Universe."
It's not OLED. It is in fact just a solar panel connected to a Sony PRS-505. Quite a nice idea though.
This idea is as old as the hills (or at least mobile phones). It will never really work well though because who wants to waste their phones battery on relaying other people's data?
They can't as far as I know but you still need to convert them to &'s.
Well that's an overly complicated and... well *wrong* way to do it. The correct solution is:
1. Escape all <'s and >'s and &'s in the input.
2. Interpret BB-code to add links & basic formatting.
Simple.

Pedant.

And it's actually £10/month in the UK. That's $16.70. Way too much if you ask me. I might be tempted to pay £5/month though...

Indeed. One of the things I don't like is that you're forced to use Java. I'd much prefer objective-C.
Furthermore this is the first carbon composite airliner ever made. It's obviously going to have more problems than another aluminium plane.

I wouldn't call it a bug... :-)
They don't seem to have many in the UK either. Most of their adverts are for their premium service rather than from third parties.
They'll never break even with the service as it is. Mark my words. What they should do is lower the premium service to £5/month.
No, with Spotify you can choose the songs you listen to yourself. It's basically iTunes with a massive library and occasional adverts.
Actually I say occasional adverts. For some reason mine has completely stopped playing any. I have no idea why but I'm not complaining!
