I regularly spawn several thousands of threads in the C++ servers I write, and they perform well. At least 40% of FAANG companies just reduce the size of their per-thread stacks. "Thread per-connection" works just fine, and when

My biggest problem with less(1) is that the regex engine is unreasonably slow. When processing large files, I frequently need to search with grep (or more recently, rip-grep) with large -A/-B buffers, and then pipe that through less

This sounds remarkably similar to the (western) Catholic theological concept of "mental reservation" ( https://en.wikipedia.org/wiki/Mental_reservation ).

It is most definitely not an overstatement. I have over 425 hours in Hollow Knight. I stopped playing Silksong in 8 because it felt like unfun masochism.

This contradicts the most common view of Christians throughout history, especially since the simplest reading of Romans 1 expresses exactly the opposite view: "Ever since the creation of the world his invisible nature, namely, his eter

My experience has been the opposite. The number of customer service representatives I speak with that simply can't comprehend the NATO phonetic alphabet never ceases to surprise me, somehow. More than half the time I'm nearly

"Synoptic" is simply the adjectival form of "synopsis": Matthew, Mark, and Luke all strive to give a synopsis of Jesus' life, organized primarily around a chronological retelling of his approximately three-year mini

It's impossible for your fact and the fact you're replying to both be true. Water is denser than butter, and the nearest star to the sun is about 4.3ly away; if your fact were true, the universe would be a black hole. A cubic lig

I've written a lot of high performance/scale C++ code using a lot of data structures over the years, and ordered iteration has been very rarely needed; unordered data structures still rule the day in performance the vast majority

This really doesn't seem to be comparing to comparable data structures. For int map specializations like this, the optimized alternatives are things like Judy (which is looking quite aged these days) or roaring bitmaps, not to mention

Why do you call it a "national security asset"?

For what it's worth, the only state in the United States which agrees with your philosophy is Texas. Every other state requires an imminent threat of death or grave bodily harm to justify the use of lethal force. (And honestly, Texas

It's probably a violation of the First Sale Doctrine, which is well established in US law.

"Taking full control of your I/O and buffer management is great if (a) your developers are all smart and experienced enough to be kernel programmers" is already an appeal to authority in itself. We shouldn't apply a high

You're issuing a correction for your original post, then? Haskell can circumvent the type system with unsafeCoerce and cast anything into anything else, therefore it (by your definition) is weakly typed. Same thing with Ocaml and Obj

by jemfinch 3y ago
Calling C/C++ "weakly typed" is just functional/academic language snobbery. They have some automatic type conversions (more than some languages, less than others) and they have casts that allow programmers to circumvent

Please stop repeating this falsehood. "My sister had already had a couple of police visits about the previous incidents."

The point isn't a point at all, since their sister had already notified the police and given them a chance to do something. Read the article: "My sister had already had a couple of police visits about the previous incidents.&quot
