LOC is not a good way to measure the "bloatness" of a software. There is a significant amount of device driver code in linux kernel. With the number of devices exponentially increa…

Things have changed over the years. Even if the developers have patched gcc, or "own" gcc, linux still have to be built with gcc 4.4 otherwise many distro will have problems, so it…

There are many projects recently titled like "xxx in Rust" or "xxx in Go", rewriting an existing software, seems to be built not because there is a problem in the existing software…

I think what most people mean when they say 'regex' is actually 2 thing: 1. The syntax of that pcre-like regex engine accept. 2. regular language, a kind of formal language. Many r…

Agree that using vector instruction is not crazy at all. I am quite interested when I see the article title, and then deeply disappointed after I read it. I was expecting something…

It is difficult to build a TUI. Just to draw several progress bars might take a whole day to implement.

Dear Tanenbaum, in case you are reading this, thank you for creating Minix. I have the first edition of your Design and Implementation of OS. That enjoyable read makes me a program…

Agree. Though micro looks very good as a light weight editor for programmers, arguably better than vim in some way, it cannot move (neo)vim users like me away. Borrowing Linus Torv…

Don’t abuse the term “isomorphics”. To prove 2 groups are isomorphic mathematically you have to show there exists a product preserving map between the groups. Just kidding.

Flame war between bash/fish/zsh/powershell is almost meaningless to beginners, because the basic skills are common to all shells. (That said, you will love zsh once you use it) I l…

Single quote denotes a symbol in scheme. But this snippest is not strictly scheme. Perhaps it is SXML but I am not familiar with it.

No , inhertiance is not a key part of oop. Look at Rust and Go. https://lwn.net/Articles/548560/

Loop unrolling as shown by the author is quite common in maths functions. It is still quite readable and ensure good performance. Openblas use a similar tricks in the old days when…

To me this is strikingly beautiful, compared to gnome and kde overkilled interface

That is definitely 5-6 years of study, because QFT is not taught in undergrad level in most cases.

I mean they just hate GPL, not open source. Just look at the removal of BlueZ GPL library in 2012. [1] https://lwn.net/Articles/597293/

Google is just afraid of GPL I think.

This is not only an optimisation. Power of 2 is necessary to avoid discontinuity. See the comments below the article for explanation.
