Jan SchaumannAdvanced Programming in the UNIX EnvironmentWeek 4: time(3) is an illusionHaving revisited the atime, mtime, and time in our last video segment, we now have to come to terms with time(3) itself. We'll discuss managing the data structures and handling arbitrary concepts such as leap seconds, timezones, and (ugh) Daylight Savings Time. It gets silly real quick.<a href="https://youtu.be/3N2aH1vUacQ" rel="nofollow noopener" translate="no" target="_blank">https://youtu.be/3N2aH1vUacQ</a><a href="https://mstdn.social/tags/apue" class="mention hashtag" rel="nofollow noopener" target="_blank">#apue</a> <a href="https://mstdn.social/tags/unix" class="mention hashtag" rel="nofollow noopener" target="_blank">#unix</a> <a href="https://mstdn.social/tags/programming" class="mention hashtag" rel="nofollow noopener" target="_blank">#programming</a>

Jan SchaumannAdvanced Programming in the UNIX EnvironmentWeek 4: atime, mtime, ctimeIn this video lecture, we start looking a little bit closer into what our systems think of "time", something that experts most accurately describe as a big ball of wibbly, wobbly, timey, wimey... stuff.

Christoffer S.I wonder how long until we see an "AI-native coding language" that will be entirely devoid of readability, but instead be entirely based on tokens incomprehensible to humans.After all, why use human-readable language to instruct computers? It makes no sense to me.Sooner rather than later, I'm guessing that Microsoft, Google, or some other giant will have invented a new language optimized for AI code generation.The consequence of this AI code language will be that even more power is concentrated in the hands of the very few, and building applications, and what they look like, will eventually be dictated by the languages provided by the giants.I hope I'm entirely wrong.<a href="https://swecyb.com/tags/LLM" class="mention hashtag" rel="nofollow noopener" target="_blank">#LLM</a> <a href="https://swecyb.com/tags/AI" class="mention hashtag" rel="nofollow noopener" target="_blank">#AI</a> <a href="https://swecyb.com/tags/Programming" class="mention hashtag" rel="nofollow noopener" target="_blank">#Programming</a>

randomwizardReading through old Pascal from the 70s. Something else Pascal had that was handy and sort of lost along the way in most popular languages.You could define a subrange type in Pascal.Type // Defines an integer subrange type // in the range of 10 to 123 TNumber2 = 10 .. 123; // Defines a character subrange type // in the range of A to Z (all uppercase) TLetter2 = 'A' .. 'Z';Sort of like a more narrow type system definition. Instead of writing RegEx all over the place to check number ranges, the compiler had it built in to check ranges.<a href="https://wiki.freepascal.org/subrange_types" rel="nofollow noopener" translate="no" target="_blank">https://wiki.freepascal.org/subrange_types</a><a href="https://social.vivaldi.net/tags/code" class="mention hashtag" rel="nofollow noopener" target="_blank">#code</a> <a href="https://social.vivaldi.net/tags/programming" class="mention hashtag" rel="nofollow noopener" target="_blank">#programming</a> <a href="https://social.vivaldi.net/tags/pascal" class="mention hashtag" rel="nofollow noopener" target="_blank">#pascal</a>
