To me, Linus lost all credibility after I've seen what mess Linux kernel code is, and how well-written BSDs are.

ConTeXt is an awesome package. Its "only" drawback is that it's unsupported by publishers. I thought about writing my thesis in ConTeXt, but then I couldn't have easily reused the text from published papers.

Why do algorithm books generally devote so much space to FFT? It seems like it has very narrow applicability: apart from signal processing and multiplying big integers or polynomials, what else are they useful for? Wouldn't it be better to

Tesla uses apparently Li-ion battery. I wonder why I han't experienced the same problem with other electronics using that same type of battery. For example, I had my fully-charged mobile stored away for approx 5 months without charging. W

The point is that O(log N/log log N) is not O(log N): they have broken the informatic-theoretic bound of O(log N) in linear space using "ordinary" operations. (Previous such works used exotic machine models that had little to do with how

Too bad that you can't easily judge upfront which of those data structures and algorithms are really usable in practice. For example, fusion trees may seem like a cool idea, but they're totally impractical, as also admitted by the authors (

Yet another language with significant whitespace and otherwise python-ish syntax. No thanks. I would have used Python if I wanted to. Plus, any source->source translator makes debugging a pain.

Mucking around with CSV files in command-line is painful. Been there, done that, got annoyed by many limitations of that approach, bit the bullet and learned R. It is somewhat weird language, but it was one of the best decisions I ever mad

This is about maintaining invariants, and I interpret the "any random input" from the parent question as "input that breaks the preconditions the function expects of its inputs." With str* functions the assumptions are that the string is nu

If "undefined behavior" were an argument for keeping features out of the language, the language we would have ended up with would not be C.

"Problem" 1 is also well-known behavior for people who actually bother to learn it properly. C being such small language, there is almost no excuse for not learning it properly if you deal with it daily. Also, some C compilers warn about s

C and C++ are efficient for general-purpose programming, if you know how to use them. C is here to stay because it is lingua franca of the computing world: OS APIs are defined in terms of C functions, and I know of no libraries in wide-sp

How does it have negative effect? Consider three cases: 1) an algorithm is designed and patented, and the inventor has the right to use or license it. 2) an algorithm is designed and never published, i.e., held secret for proprietary use o

Your example with "MouseClick" succintly explains what I feel is wrong with much of software development today that tries to follow "modern" OO practices. Blame it on the language, or on people who try to mold the world into familiar casts

What "standard things"? shared_ptr is only one of many possible ways to keep track of object lifetimes. Rolling your own reference-counted smart pointer might be a code smell, but not choosing reference counting is far from that.

Why do we make things so complicated? Because C++ is a low-level abomination pretending to be a high-level language. Let's start. - Allocators in the STL are a joke, so you can't use them for implementing different memory models. So you e

I'm tired of marketing boost as "modern C++". Alexei Alexandrescu, the author of "Modern C++ design" book has since gone on greener pastures and got involved with the D language. He participated in the design of D, and wrote a book about i

It is not as fast as it could be. It is an implementation of ordinary hash table, meaning that also a successful search requires comparing two strings several kB long. What I propose is to reduce ALL symbols to their hashes (SHA1 is 20 byt

This is an improvement of existing hashing scheme in ELF object files, and is completely different from what I proposed.

Not to mention link times: templates generate HUGE mangled symbols, with corresponding increase in memory and time as all those strings have to be stored and string-compared. I've long wondered about why doesn't any C++ compiler implement s

No, it's not. Adding a new built-in type that doesn't participate in type-checking in any meaningful way just clutters the language. _Bool is like int, just having unspecified size and slower, since the compiler has to ensure that it shall

I gave up from C99 and its successors when I saw that they introduced _Bool. Actually, I've never understood the meaning behind having a boolean type in any language. [It would kinda make sense if conditionals accepted ONLY boolean argum
