The thing is, there is always tar(1) even in the most basic of distributions. And everyone uses tar.gz's or .bz2's or whatever for distributing all kinds of things, so tar is pretty ubiquitous. But the moment you want to do some C

Eh, that's really just a side effect of almost 50 years of constant evolution from a 8-bit microprocessor. Take look at VAX [0], for instance: its instruction encoding is pretty clean yet it's an actual example of a CISC ISA that

(Almost) any instruction on x64 that writes to a 32-bit register as destination, writes the lower 32-bits of the value into the lower 32 bits of the full 64-bit register and zeroes out the upper 32 bits of the full register. He touched on i

A seasoned C programmer knows that "&arr[index]" is really just "arr + index" :) So in a sense, the optimizer rewrote "x + y" into "(int)&(((char*)x)[y])", which looks scarier in C, I admit.

Honestly, x86 is not nearly as CISC as those go. It just has a somewhat developed addressing modes comparing to the utterly anemic "register plus constant offset" one, and you are allowed to fold some load-arithmetic-store combina

Depends what you count as a result, I guess. "There is exactly N flips of a single kind" is also a viable definition, just as "The exact sequence of flips was x_0, x_1, ... x_199" is.

Well, yes. But the expected deviation from the mean is still ≈7.07. And the probability that the outcome will be either 93/107 or 107/93 is (slightly) higher than the outcome being exactly 100.

You mean, what does sequence A004431 [0] look like? Well, like itself. Some of its properties are also listed at that link. [0] https://oeis.org/A004431

There is an amount of people who own, well, in the past we could say "means of production" but let's not. So, they own the physical capital and AI worker-robots, and this combination produces various goods for human use. So t

And it all happens in the Russian part of Steam, so... so what? Steam also IIRC censors such things for UAE, and e.g. swastikas in WW2 games for Germany (or was it Australia?) which is... fine?

And they also took care to replenish the deposits of iron, copper, tin, lead, and rare-earth ores plus coal and oil before ultimately disappearing. Very considerate of them!

What a strange way to date it. "The Roman sarcophagus from the III century CE is unearthed in Budapest". Okay? The Roman Empire did span that far in that time period, and IIRC that time period is already quite well represented arc

Go's "defer" can't prevent return from actually returning from the function. Most of the time, it can't change the computed return value either, unless you go out of your way and use named return values. Go's &

First, if we're talking about practicality, and not just theoretical considerations, then the numbers should not be stored as Peano integers a.k.a. base 1 in the first place. Use lists of 8-tuples of bools or native machine integers or

The strtoul()/strtoull() also have a somewhat strange semantics regarding the leading '-': it will apply it to the (unsigned) result, so e.g strtoul("-40", ...) happily returns 18446744073709551576. Also, the wordin
