Presumably it results in an error, but if the return value isn't checked then that's fine.

What nonsense, an extra 9ft of cable is ~14ns (given it's completely passive). A human would struggle to detect 14ms (6 orders of magnitude difference) and it'll be completely swamped by polling latency.

It's amazing how the cost of these MEMS components hasn't fallen at all over the last 20 years whereas the price of other MEMS components (eg. gyroscopes, accelerometers, microphones) have.

Building the full adder might even make it less ICs overall. Lots of tricks are lost here, for example the subtraction logic can be used to implement a NOT function if you add to zero. Rather than having an extra XOR chip you can implement

Once we properly understood it we realized Maxwell's equations could be reduced to one equation (the d'Alembert operator applied to the electromagnetic tensor gives 4-current scaled by a constant). I'm sure whatever turns up

GSM is definitely possible, but you'd struggle to get more than 2kbit/second (and that'd be over a good connection). You'd probably need FEC to pull it off.

Not necessarily. You could go the way of busybox or uutils and have a single binary with many hard links. So 'ls', 'wc', 'grep', etc can all point at a single executable which dispatches to different functional

I use netctl and find it works very well. For non-wifi use cases you probably don't need anything at all (maybe dhcdcd).

No, LGDT is actually an instruction (like MOV or ADD). You'll be hard-pressed to get a C compiler to emit that without using inline assembly. http://x86.renejeschke.de/html/file_module_x86_id_156.html

Lots of people have to worry about single digit microseconds with high throughput.

It's not worth it, because as soon as you go down this route you're going to be constantly thinking about the GC. If I add a cyclic reference here will that make GCs longer? Maybe I should have a free list and reuse these objects

The last time I was in that situation, the only option was lisp. I'm still supporting a lisp environment for that one piece of code.

Maybe not most people, but Iceland is a relatively big country to completely exclude your product from (especially for such a silly reason). If the OP were Icelandic I think that'd be a pretty good reason not to switch to Android.

You're not "so wrong on your stock picks", you're wrong almost exactly 50% of the time (well actually you should be wrong about 40% of the time, but those 40% of bad picks will lose you about the same amount of money as

It used to be much much worse, to the point of being absolutely unusable on the latest iPhone. I actually cancelled my FT subscription for several years solely because of the poor performance of that site. It still has a nice bug where it r

Right, modern CPUs can do 50 gigaflops per core. There's absolutely no chance we're going to have non-volatile storage that can do hundreds of billions of IOPS any time soon (if only because you won't be able to get that much

Even identically configured VMs have different MAC addresses, etc (otherwise they'd never be able to communicate via ethernet).

All new Intel CPUs now contain a built-in true hardware RNG (RDRAND), why not just use that? Unless you think Intel might have put some kind of backdoor in it (hard to believe), in which case they could also be intercepting your USB communi

You can also use idle3-tools on Linux to do this, which saves having to reboot into DOS. It's even packaged for Debian/Ubuntu. $ sudo apt-get install idle3-tools $ sudo idle3ctl -s 138 /dev/sdx (for 300 seconds)

There hasn't been such a thing as a north bridge since Nehalem in 2008. These days the access won't even hit RAM it'll just go to on-chip L3 cache.

People would just look at how the prices move on the 'free for all' market and then trade the real stock market using that information, thus insider trading on the real stock market would ensue. You can't have it both ways, y

Right, I'm thinking of the "embarrassingly parallel" sort of problems, where you can shard the data (for example by city, country, company or some other obvious classifier) and give one shard to one server. I'm you were

Actually you can normally get away without resorting to "big data" techniques at 1PB scale, it's probably around 10PB that you're really forced to start thinking about things like hadoop style map-reduce/rack-locali
