Back in the 90s, it was common to see t-shirts and other apparel festooned with nonsensical strings of English letters in China, an attempt to be “cool” by appropriating the design of lettered Western clothing without any of the content. Hu

It’s actually a shame that there is no `mov rip, ...` instruction. That would make it truly Turing-complete. ARM has this instruction! (Of course, jmp [...] works just as well, but it isn’t called mov)

I don’t know where to start with your comment. > If the claim is extremely unreasonable ... most people can tell it’s unreasonable. Surely you must have far more faith in humanity than I do, or you would not make this statement. One only

It also messes with dictionary lookup! It adds this nonsense if you select more than two Chinese characters, and so it makes it really hard to look up four-character Chinese idioms in my dictionary (which are, inexplicably, frequently missi

An interesting coincidence: it was recently (2019) discovered that the fastest way to multiply two n-bit integers, in time O(n log n), involves 1729-dimensional Fourier transforms: https://hal.archives-ouvertes.fr/hal-020707

GCC has had case ranges as an extension for a long time now: https://gcc.gnu.org/onlinedocs/gcc/Case-Ranges.html It’s a far cry from general pattern matching (a la Rust, Scheme) but it’s helpful in some circumstan

How does this fare against Python's famous Timsort (used by several languages and systems)? How about the dual-pivot quicksort used by Java for primitive arrays? Someone has to have put together a nice benchmark for comparing many sort

If you pleaded the fifth on your password, the court might be able to compel you to enter the password such that they don’t get the password but do get the data. The next question is, if doing so immediately decrypts a file (e.g. a text f

Sandboxed Java apps don’t. Here I’m talking about apps that you can’t get on the App Store, many of which are older Java programs which haven’t been updated to use the newer APIs. The push to force sandboxed apps to use the system dialog ha

With sandboxing, macOS is now forcing devs to use their file selection dialog because it will grant access to the selected files - a custom dialog box has no such blessing. It's nice, actually; it's finally making the file selecti

The statute on mail fraud (18 U.S.C. § 1341: https://www.law.cornell.edu/uscode/text/18/1341 ) clearly states: > places in any post office or authorized depository for mail matter, any matter or thing whate

That sounds like mail fraud - and you could get prosecuted by the feds for that. Not something I recommend trying, especially in the US.

There's also `echo -ne '\0'`, which works similarly (it tells echo to interpret the escape sequences).

Classic MacOS used : for the directory separator, so you could freely put / in your filenames. Modern macOS converts / in the UI to : under the hood in order to retain compatibility, while banning : in the UI (the same restriction

Unexpected places where you can use null bytes: gets, fgets and scanf("%s"). All three will read and store null bytes into your string from the input, and keep going: gets and fgets only terminate at a newline character and scan

The kernel is composed of a bunch of independent source files which share headers; thus, running them through a preprocessor would massively overcount the LoC. (In theory, this would get you the “actual compiled LoC” but that’s a useless me

On the other hand, these are running on some big cluster with a whole bunch of CPUs, so I wonder if you’d still get 3m per build on something like a laptop?

A clean build of the Linux kernel can be very fast, but the config is very relevant. A custom build specific to your hardware will touch only a small fraction of the overall kernel tree, whereas a generic build including a large swath of ha

GDB supports expressions on both sides of the @ sign, so you could also probably do p *values@array_size(values) and that is probably short enough that you could wrap that in a macro. (Of course, Python is definitely the more exten

Another one to add: if N is big enough, even statistically improbable events like single bit flips in memory become likely or even nigh-certain. For example, if you set up a bunch of fake domains that differ from real domains in a single bi

OK, so I'm genuinely confused about what your objection to global state is. You mention issues with assignment, and so on - those are issues with Python `globals` and variables in the global namespace, not issues with global state per

The very low precedence of & is the source of an unbelievable number of bugs, especially in embedded programming. For example: if(PORTA & 3 != 0) looks like it should be true if either of the low two bits is set. But actually, it on
