For a library, if the user input is wrong, throw an error or an assertion failure. It shouldn't be causing an uninformative segmentation fault which your library does. The fix is a trivial. Why so defensive?

Probably many have written a vector header like this. It baffles me why this one reaches the front page of HN given that the implementation is not that great. A few problems (some have been mentioned by others as well). 1. not using "d

The parent post said no E2EE for group chat. Telegram doesn't seem to support that according to the linked page. Telegram group video chat only allows up to 30 people for the time being, which is far too limited. Also, group chat is no

My biggest complaint about all scandum's sorting algorithms is that it doesn't support guaranteed inlined comparisons. Without this feature, the result depends on the compiler behavior, making the results hard to interpret. This p

I am thinking more about sorting, say, 20-byte or 24-byte custom structs. Directly sorting arrays is probably faster than sorting pointers to arrays. At least in my applications, I rarely just sort numbers; I more often sort numbers along w

In the source code, it is not apparent where the size restriction comes from. It seems to me that it can be easily modified to work with any data types. Maybe I am wrong. I am more concerned with this sentence: > Blitsort's perform

You can go down the route to say C++ is largely a superset of C. You can always write C++ in the C way, so you don't see simplicity is an advantage of C.

Think about compiling a large C++ program and its dependencies every time you run the generated executable. This is sort of like what is Julia is doing.

by acmj 5y ago
This looks straightforward to me and probably to many C programmers. It is natural to write this as well as other styles you can come up with. Nitpicking is a bigger problem which distracts the attention to the real issue.

This would be my guess. MS just can't openly admit they censor in China even though everyone knows this is how they are allowed to operate in China, so they use "human error" as a bad excuse.

Static compilation is not needed for numeric computing which Julia is great at. However, Julia is advertised as a general purpose language, which IMO is obvious in your "What is Julia?" section. You pose Julia as a mighty language

by acmj 5y ago
IMO, if Julia lacks the necessary tooling, don't over-advertise it. When I say the lack of static compilation is a design problem, I mean such a critical feature should be in v1.0. Without it, many common tasks in other languages becom

Couldn't agree more. What you said is a design flaw that the Julia community keeps denying. The Julia community also behaves defensively when it comes to performance. They refuse to accept that Julia doesn't compete with C/Ru

by acmj 5y ago
I agree. The Julia community is defensive. When you criticize Julia, often their first reaction is to say you are doing something wrong or to convince you Julia is perfect for everything. I was enthusiastic about Julia but not anymore.

Thanks for the correction, but the key signature in a piece may be changing. Also, those with perfect pitch can tell the key signature from a short passage if there are few accidentals.

I am no musician. I heard quite a few musicians, with or without innate perfect pitch, can tell the keys in a chord, though maybe not to the 100% accuracy. For example, something like what the kid is doing in this video [1]. I am a bit surp

This increases code complexity. Also, for many applications, we prefer to have a max field for dynamic strings. Each type of string representation has its own pros and cons. This comes back to my original comment: there is not a universally

by acmj 6y ago
I am not sure there is a universally better solution. If a function takes both string and its length (e.g. strncmp), there is no guarantee that the length is correct. Or like C++, you always represent a string by a (len,max,ptr) 3-tuple, bu

If I were the maintainer, I would create cryptography2 and put the original cryptography into the bugfix mode. It is time to move to a safer language, but breaking backward compatibility is always bad.
