I used many TUI-based TODO lists, there are plenty of them in GNU/Linux: todolist, ikog, todo.txt, yokadi and others. All of them are too simple for serious use, I think. But it looks like I've eventually found the golden middle - powerfull enough but still terminal friendly utility. Its name is Calcurse.

One more tool looks very similar to Calcurse and definitely deserves your attention. This is Taskwarrior.

Электронная книга на русском с последовательным введением в язык Perl. Книга особенная, потому что фокусируется на примерах реализации алгоритмов, а не на тонкостях самого языка. Список примеров просто огромен.

This longread is a great way to show non-technical people what the programming is and why it is difficult but still interesting.

It's better to read the article in the desktop, full-featured browser, because the text contains many dynamic interactive examples.

Terry Davis has passed away in August. I didn't know that. In spite of his conflictness in community he was a brilliantly productive programmer. His last year was dufficult and finished tragically. Use links below to read more about him and his software.

Many members of the OSDEV community thought that Terry Devis was a kind of computer freak and considered his OS as an odd job. But, actually, Temple OS always had many strong features that one couldn't find in mainstream operating systems. The following article reveals such hidden things.
