The official Ruby interpreter is written in C. That means that everything you can do in Ruby, you can also do using function calls to Ruby's C API.

personally think that developers shouldn't care about code beauty, because that's not their job. Instead, they should focus on creating great products, which is infinitely more satisfying. Code Fashion What defines beauty in code? Just like for clothes, opinions on the subject may vary. Each year, we find new trend-setters, like Jeff Atwood, Martin Fowler, or Eric Evans. They offer convincing arguments to explain why pattern A is better than pattern B. Until someone else publishes a book, explaining that pattern C is much, much better

out of 5 dentists agree that multi-threaded programming is hard to get right. At the end of the day, all that the GIL guarantees is that MRI's native C implementations of Ruby methods will be executed atomically (but even this has caveats). ... So the GIL doesn't 'solve' thread-safety issues. ... One way that we work with hard problems is with good abstractions. ... We're seeing more and more abstractions around threads. An approach that's catching on in the Ruby community is the Actor model of concurrency, with the most popular implementation being Celluloid. Celluloid provides a great abstraction that marries concurrency primitives to Ruby's object model. Celluloid can't guarantee that your code will be thread-safe or free from race conditions, but it wraps up best practices. I encourage you give Celluloid a try.

syntax ako ruby, ale jazyk je kompilovany, lahka praca s C kodom

A few years ago, I took on a freelance project to implement an Internet Explorer component in C++. I was billing a healthy hourly rate on other projects at the time, but this particular client insisted on a fixed price. In a bout of temporary insanity, I made an exception.... Every developer knows that accurate software estimation is not possible even when perfect information is available about project requirements (i.e. practically never).....

Z toho clanku "death to JIRA" vypichujem: For some reason many companies today seem to be terrified of the prospect of writing more than a couple of paragraphs of clear and simple prose. But a well-written 8-page document can define the nuances of a complicated system far better than a whole cumbersome flotilla of interlinked JIRA tickets. ... Feature planning is about communication. JIRA is fundamentally a terrible way to communicate the requirements of a complex system. Words in a row, if written well, will always be better. A v dost vela veciach suhlasim.

These days it's a pretty bold claim if you say that you invented a sorting algorithm that's 30% faster than state of the art. Unfortunately I have to make a far bolder claim: I wrote a sorting algorithm that's twice as fast as std::sort for many inputs.

K šperkom či dôležitým listinám v bezpečnostných schránkach sa môžu klienti bratislavskej pobočky ČSOB na Námestí SNP dostať aj pomocou odtlačku prsta.

Vojaci obvykle používajú biometrické zariadenie, ktorým snímajú odtlačky prstov a očné dúhovky. Zariadenie však nemali vtedy k dispozícii, a tak údajne odsekli jednému z usmrtených ruky, aby nemuseli prevážať jeho telo na základňu Tarín Kót v provincii Uruzgán.

Na existenci průkazu se přišlo ve chvíli, kdy se poštovní doručovatel pokusil doklad donést příjemci, ale na dané adrese ve státě Rádžasthán žádného Hanumána nenašel. Když se podíval na fotografii, došlo mu, že jde patrně o žert. Není zatím jasné, komu patří sken duhovky a otisk prstu na průkazu.

commity Kernighana, Ritchieho, Bournea .. The goal of this project is to create a git repository representing the Unix source code history, starting from the 1970s and ending in the modern time. To fulfill this goal the project brings data from early snapshots, repositories, and primary research. The project aims to put in the repository as much metadata as possible, allowing the automated analysis of Unix history. The following table illustrates the type of material that can be gathered and integrated into the repository.
