Probably not the right thread for it, but you're answering questions, so what the hell!

Will the non-javascript classic (the REAL classic version) be staying? I prefer that version, but I sometimes have to browse with scripts disabled in order to get it to work (actually, I usually read from Dillo or Links2 neither of which do JS, because I like the responsiveness). Unfortunately, though this means that I can't metamoderate any more since that requires JavaScript.

Yes because waiting so long that vendors develop incompatible libraries and then shipping incredibly buggy system libraries then not fixing them for a whole major version has no effect on whether the apps reliably support the feature, because apps are *magic* and don't need system libraries.

BLE on android is a total clusterfuck and as a result app compatibility across versions is bad.

"great games shipping for linux ..." where? i'd love to install some.

Well, I've been playing Creeper World III recently. I loved 1 and 2, and 3 is available native on Linux, where as I had to run 2 in a Windows VM. it's an indie game, so not super fancy but it runs on low-end hardware and the game mechanic is interesting. It also has a lot of built in content, a huge amount of very imaginative user generated content and a remarkably good random level generator.

It's not.

The only people who claim so are, frankly, ignorant.

The ignorance comes because Linux is easier to use for development than the alternatives. You just apt-get install the libraries you need and get hacking.

In order to make something portable you need to do what you have to do on Windows anyway: package all the libraries with your program.

It's just that by default Linux is much easier in that regard.

Except Bluetooth Low energy.

For some reason despite having support in the Kernel, it took them ages to support it on Android. 4.3 or newer only unless you want to also use some phone endor's own libraries for pre 4.3. That's a pretty bad indictment when several vendors had to make their own, incompatible libraries for hardware because Android dropped the ball.

Oh and the 4.x series has some really nasty bugs too and they're only fixed in 5.x. the recommended solution is to turn bluetooth off and on again and if that doesn't work, reboot the phone.

Not an iOS fanboi (I hae no iOS devices), but Android is awful and really driving me up the wall right now.

Do you have a link for that? It's not that I disbelieve you, I strongly suspect that Intel would do that crap. I'd like to read more about it however if you hae a link handy, then stash the link for the next time this benchmark comes up.

Personally, I like the Phoronix Linux benchmarks. They're more meaningful for me since I use Linux and they're all based on GCC which is trustworthy.

The i7 4770 ocasionally blows away the FX8350 by a factor of 2, but in many benchmarks they're close, and Intel loses a fair fraction. The 4770 is the best overall performer, but not by all that much. It seems that the choice of CPU is fairly workload dependent.

For servers, I still prefer the supermicro 4s opteron boxes. 64 cores, 512G RAM, 1U. Nice.

I think this busts the physics, unless I misunderstand completely. Paging Dr. Shannon...


Think about baseband for a moment.

Let's say you hae a bandwidth of 100MHz.

You can basically change from 0v to 1v 100e6 times per second, giving 100Mbit/s.

But you can also introduce more symbols. If you have 10 voltage levels between 0 and 1 V you get 1Gbit /s.

What limits the number of symbols is noise. The datarate is symbol rate * bits per symbol. In the absence of noise, you can transmit an infinite amount of data in a 1Hz channel.

For non baseband signals, they generally use QAM to get symbols spanning the whole phase space around the centre frequency.

Comment: InGaAs? (Score 5, Interesting) 279

GaAs was the future of super-fast transistors. The Cray 3 was made from GaAs.

GaAs has a much higher electron mobility than silicon, 8,5000 versus about 1,500 for silicon. This allows for much faster switching. InGaAs has an electron mobility of 10,000 allowing even faster switching.

But that's just electrons which are used in P channel MOSFETs. For CMOS, you also need N channel MOSFETS. The kicker is that GaAs and InGaAs have respectively lower and much lower hole mobility so the N channel FETs switch rather slower than silicon.

CMOS is by far the only architecture. Historically it is the most power efficient since it only spends energy switching. On high speed, small scale CMOS, however, lots of power goes into the switching itself, the switching is fast enough that the devices don't really act very ideally and there's a lot of leakage.

Perhaps at very extreme ends, other architectures can compete, power wise.

After WWI, many chemists argued that there was no point making treaties against chemical weapons because you'd effectively have to outlaw the entire chemical industry... Chlorine gas & phosgene were both part of the dye industry.

Not only that but chlorine prodiction is utterly trivial: it might not be the cheapest way, but you can get it by electrolysis of brine.

Still, marriages can work as long as the man keeps the funds coming in, does whatever the wife tells him to, and sacrifices his sex life.
That's what it takes to "make it work" men!

The real problem is (of course), that if you have to "buy" a woman, then it's prostitution anyway, and she doesn't really love you.
So why bother with marriage at all?
Face it, if she really loved you, she'd stick with you without needing your money, or needing to be married. However, we all know how that works out :(

Works out fine for me. Sucks to be you, I guess. If you assume all women are massive raging assholes, and go through life as such, then you will never find one who isn't.
