Dubai's Climate-Controlled Dome City Is a Dystopia Waiting To Happen

am 2k Re:Asimov predicted it! (265 comments)

Not quite. The Earth moved underground, while Trantor built domes aboveground. However, the end result is pretty similar, and he also stated the same reasons for doing so (which pretty much matches what they're saying about this project).

Dubai's Climate-Controlled Dome City Is a Dystopia Waiting To Happen

am 2k Asimov predicted it! (265 comments)

That's what happened to Trantor in Asimov's Foundation series:

Trantor is depicted as the capital of the first Galactic Empire. Its land surface [...] was, with the exception of the Imperial Palace, entirely enclosed in artificial domes.

And so it begins...

Swedish Farmers Have Doubts About Climatologists and Climate Change

Well, if the Gulf Stream ceases to exist due to the changes (which has been considered a couple of times), the Swedes won't be all that glad I guess. Siberia will look like a warm and cozy place in comparison. Rome will be a bit colder than New York.

Supreme Court Rules Against Aereo Streaming Service

am 2k Re:Predictable (484 comments)

So, why is the spirit of the law ignored when it comes to tax code? Why are there so many companies with their seat in places like the Cayman Islands or San Marino, while 99% of the work force is in other countries like the US or somewhere in the EU? They still don't have to pay any taxes.

US Supreme Court Invalidates Patent For Being Software Patent

am 2k Re:Yes, but for the wrong reason (220 comments)

But what's an abstract idea?

Isn't the definition that you have to be able to give a patent to a developer skilled in the specific art and he/she can implement exactly the device described by the patent without inventing anything new? If that's not possible, the patent is supposed to be invalid because it's an abstract idea instead of a concrete implementation.

Fixing the Pain of Programming

am 2k Re:Debuggers (294 comments)

Simplest case, trying to debug remote code running on a server for which you have deploy-but-not-debug permissions on (this comes up a lot for me, actually).

For these cases, you should set up a local mirror environment where you are allowed to debug. Of course, if you can't reproduce the problem locally (because of system-interdependencies or a critical database you aren't allowed to copy for testing due to privacy issues), you have a problem...

Apple Fixes Major SSL Bug In OS X, iOS

am 2k Re:Ability to run arbitrary code. (96 comments)

Executing arbitrary code is how the jailbreaks work. They exploit some weakness to patch the system, removing a few safeguards in the process (that's why there are some viruses out there that only affect jailbroken iOS devices).

OpenSSL Cleanup: Hundreds of Commits In a Week

am 2k Re:I would think (379 comments)

If a change is security related and non-obvious, then won't doing it in such a rush probably introduce new bugs/vulnerability into the code?

I guess you're not a programmer? When programming, you develop mind models of the code. This means that you can see behind the structures and write complicated stuff very quickly. After a while of not working on the code, you forget that model, and small changes are very dangerous, since they might result in side effects in other parts of the code you didn't consider.

That means that when you're constantly working on the same codebase and add features quickly, you get better code and less bugs. Note that this only stands true without a deadline looming ahead (which I don't think the OpenBSD devs have), since then you tend to make dangerous shortcuts and litter the code with "FIXME"s you tend to forget about.

That's also how hackathons work. I've been able to create full products in a weekend that otherwise would have taken months.

OpenSSL Cleanup: Hundreds of Commits In a Week

am 2k Re:I would think (379 comments)

The often repeated mantra that high level language compilers do a better job than humans isn't true, and doesn't become true through repetition. The compilers can do no better than the person programming them, and for a finite size compiler, the optimizations are generic, not specific. And a good low level programmer can take knowledge into effect that the compiler doesn't have.

While I agree, there are also specific cases where a human cannot reasonably do an optimisation a compiler has no troubles with. For example, a CPU can parallelize subsequent operations that are distinct, like talking to different units (floating point math, integer math, memory access) and not using the same registers. A human usually thinks in sequences, which require using the result of an operation as the input for the next operation. Everything else would be unreadable source.

Finding distinct operations and re-ordering commands is easy in compilers, and the optimized result has no requirement of being readable.

C tries to find a middle ground there, where the user still has a lot of possibilities to control the outcome, but the compiler knows enough about the code to do some optimizations. The question is where the correct balance lies.

IRS Misses XP Deadline, Pays Microsoft Millions For Patches

Windows XP did not instantly become unsafe on April 8, 2014, the date Microsoft calls the "end of life" for Windows XP.

No, it has been unsafe for at least a few years already. Windows XP does not support any encryption that's still considered secure.

Blender Foundation Video Taken Down On YouTube For Copyright Violation

am 2k Re:Stop using Youtube (306 comments)

my company wrote, directed, filmed, and edited a music video for a lesser known artist who is a friend. We did it pro bono because he is a friend. We posted the video to YouTube and he started using it successfully to promote himself and get more appearances. [...] That bigger company claimed they owned the copyright on the video. Google happily revoked our right to monetize it and gave us the option to take it down or let the bigger company monetize it.

Well, this sucks, but it might actually be legally correct: When you friend signed away his soul to the record company, he gave them every right to act this way. As such, your company would have had to make a contract with the soul owner, not with the poor remains.

Many musicians seem to be very naive and don't realize this when they sign up with a publisher, not even years later. Many don't even seem to think it necessary to point this out when they're doing contract work, like for indie games, even though it's very relevant. YouTube casters (which are the main PR for indie games) are not allowed to review games that come with this kind of tainted music. They are not even allowed to show trailers of the game. The casters not getting paid for their work is the mildest of results from violating this law.

I've even seen musicians that tried to argue with their masters about that they would like them to allow game reviews, but it's a very sorry sight.

Facebook Buying Oculus VR For $2 Billion

am 2k Re:Other HMDs? (535 comments)

I fail to see the difference between Oculus Rift and many of the HMDs that previously existed. Is this just a case where the pioneers got the arrows in their backs and the latecomers were able to monetize things?

Due to smartphones, the technology is now available to provide proper screens for HMDs. This is the critical piece that was missing previously. Also, what Palmer pioneered was using only a single lens to enhance the field of view, and doing the distortion correction in software, which wasn't possible until a few years ago (you basically need a fullscreen fragment shader while causing virtually no additional lag).

Also, to avoid nausea VR needs at least 60Hz (better 90Hz) display update rate, and you need very low latency for the head tracking (below 10ms). This wasn't possible until very recently either. For example, even the PS4 cannot do that in an acceptable resolution, you need a higher class PC for that.

Android Moving Away from XMPP

am 2k am 2k writes  |  more than 6 years ago

am 2k (217885) writes "Google has announced that the Android platform will no longer use XMPP. Instead, they want to develop their own protocol loosely based on it. The reasons they're giving on the web site have already been debunked by other mobile XMPP developers, leaving the XMPP developers to wonder about the real reasons for the surprising move.

Is this the new embrace-and-extend strategy of Google 'do no evil' Inc.?"
