The Redmonk methodology of looking at stack overflow and github seems to be far superior to the TIOBE search engine approach. There is a real story in the moves on this index: the rise of Swift and Kotlin, the stagnation of go and scala.

So if you read babies boring books for months, then their expectations are that books are boring. (Not boring = named individuals and recognizable faces.)

The bit with the person in a wheelchair chasing a duck with a broom is great. And it illustrates simultaneously two things: there is no hope that an AI driver will ever understand everything that is going on around it. But fortunately, yo

Unfortunately this is not the case! TVA has a "sell all buy all" rule, that if you are connected to the grid and generate 5kw, you are required to sell all of those 5kw to the grid (at wholesale price). Then you buy back the 4kw

AWS sells optionality. If you build your own data center, you are vulnerable to uncertain needs in a lot of ways. (1) your business scales at a different rate than you planned -- either faster or slower are problems! (2) you have traffic s

Spectre can read from other processes! Meltdown can even read across privilege levels (userland to kernel). But within userland, spectre lets you read anything. See: https://isc.sans.edu/forums/diary/Meltdown+

I wonder why they aren't using the approach others are taking. That is, compile an array access a[i] into an array of size N as a[i&M] where M is one less than the next power of two larger than N. The logical and is very fast; it c

They aren't aiming for Mars orbit. As far as I can tell, they aren't even aiming to come close to Mars. Instead (as far as I can tell) they are aiming to come close to the orbit of Mars, i.e. where Mars will be in 4 or 5 months.

I guess the output of the radar is basically a list of relative velocities for nearby large objects, paired with distance and rough direction to those objects. There is always a large object essentially all around you moving with the sam

Gah, you're right. Guess my memory is fading. There is indirect JMP, but no indirect JSR or indirect branches. And the indirect JMP as you say is not very useful.

I guess he means the retpoline. On the 6502 there is no indirect jump instruction, so you need such tricks just to achieve an indirect jump at all.

When using these patches on statically linked applications, especially C++ applications, you should expect to see a much more dramatic performance hit. For microbenchmarks that are switch, indirect-, or virtual-call heavy we have seen over

I wonder if it would be possible to peg the kernel to one processor core (or a subset of the cores) and userspace to the remainder of the cores. As I understand it, all of the memory caches that are being exploited to leak information are

What is surprising about 92 heads in a row is the low entropy of the outcome, not the sheer unlikeliness of it. Yes every other outcome is just as unlikely. But almost very other outcome has MUCH higher entropy.
