Does go even have any good command-line debuggers? All of the things I've seen either involve insanity like preprocessing your source to inject hooks in between each line of code, or don't actually work.

The short string optimization is decades old.

You don't need to control every byte for this to be catastrophic. You can't decode every password like you can with the previous comparison, but if you can generate a rainbow table that contains the password you're trying to

"Patches welcome" is not a particularly compelling response to "it doesn't run on any of the platforms people currently use".

There are several examples of this in the Java world, such as proguard. They're mostly centered around code obfuscation, but they do some useful optimizations as well.

It's actually even better than that. They're only using __int128 to hold the result of a 64 by 64 bit multiplication, and x86_64's mul instruction will give you this for free. gcc is smart enough to generate code that is lite

> Also note that SIZE_MAX is an unreasonable input, one would even say it violates preconditions. Annex K adds rsize_t, RSIZE_MAX, and friends, which restrict inputs to reasonable values. Unfortunately, it doesn't retcon the old fun

printf has type checking in every major compiler. You just need to annotate all of your printf-y functions with attributes to tell the compiler "this function does printf, the format string is the nth argument, and the format arguments

JavaScript is not simple, its features are not well thought out, and it is definitely not being interpreted. The only reason JavaScript performs well here is that multiple megacorporations have devoted tons of resources into fast JavaScript

Ruby is hilarious because importing a library in the standard library (or importing a library that uses it) can break division: https://bugs.ruby-lang.org/issues/2121

Well, there's always the accelerationist option of voting republican and hoping they burn down the government quickly enough for the resulting radical change afterwards to be successful.

They pretty much tried that, and it failed miserably.

This is true, javac only replaces individual concatentations with use of a StringBuilder, so foo + bar + baz + "!" is fast, but performing a concatenation in a loop does multiple copies for each iteration. It (or the JIT) could co

That's a thrust to weight ratio above 1 when only one of its 9 engines are firing, and running at minimum throttle to boot.

One of the best features of all of the epoll/poll/select functions is that they let you listen on arbitrary file descriptors uniformly. You can send events over a unix domain socket or a pipe, and just treat it as if it were a reg

It's a PS4 exclusive, so anyone who doesn't already have the console have to buy it ($400) to be able to have the privilege of buying it. (it was worth it)

A memory safe implementation is only a bit longer: template<typename T> T getValue(std::array<char, sizeof (T)> bytes) { T result = 0; for (char byte : bytes) { result <<= 8;

Because it should be trivial? template<typename T> T getValue(std::array<char, sizeof (T)> bytes) { return *reinterpret_cast<T *>(bytes.data()); }

The F-22 at least more or less accomplished what the program set out to do. It's hilarious to compare it to its "replacement", the F-35, a plane that attempts to shoehorn three mutually conflicting roles into one airframe to
