C# really feels like the most mature language that I've ever dealt with. Writing it feels clear, if something is wrong the debugger is very clear. The number of features that are there is incredible (especially post C# 2.0 when they added generics). Properties are delightful.How do you convert to a string? Convert.ToString(). How about an integer? Knowing only that one, it's what you'd expect! I a
Despite being around for decades, Python remains one of the most versatile and popularly used programming languages in the world. It’s a general purpose language, meaning it can be used for almost any kind of project, but it can be difficult to handle if you don’t have the right skilled python developers on your team. Python excels in AI and Machine Learning with its extensive libraries like Tenso
2012-02-07 — Fractal Benchmark Extended: Theo Wollenleben has added many more language ports and benchmarks! 2007-06-08 — I enabled optimization in C. 'gcc -O3 Mandelbrot.c -o Mandelbrot.' 2007-06-04 — I added a compiled OCAml version. Faster than both C and SBCL! 2007-06-02 — I updated the C version to utilize doubles instead of floats. Most scripting languages use doubles behind-the-scenes so th
PHP の unserialize() の 多言語での実装 2006-02-28-1: [PHP][JavaScript][Perl][Ruby] を見ていて,PHP の serialize() は便利だから,もしかしたら他の言語でも実装があるのでは? と思ったら,案の定たくさんあった. - JavaScript http://www.phpguru.org/static/PHP_Unserialize.html http://www.phpguru.org/downloads/PHP_Unserialize/ - Perl http://search.cpan.org/dist/PHP-Serialization/lib/PHP/Serialization.pm http://hurring.com/code/perl/serialize/ - Ruby http://www.aagh.
PHP ある方にエラー処理演算子を使う例をいただいたので採用。 <?php $argv = $_SERVER['argv']; if (count($argv) != 2) { die("Usage: $argv[0] filename\n"); } $buf = @file_get_contents($argv[1]) or die("Error: failed reading $argv[1]\n"); echo implode("\n", preg_split('/\s+/', $buf)); ?> 補足: PHP5ではfprintfが付いたのでfwriteとsprintfで別々に処理しなくて済む。 Perl if(scalar(@ARGV) != 1) { die "Usage: $0 filename\n"; } open f, $ARGV[0] or die($!); pri
In the last entry I argued that while learning programming languages comes at a high cost, good programmers should be proficient in multiple languages. I think of programmers as having language sets, based on the idea that knowing one language is not enough for a professional. The task then is to pick the language set wisely to minimize learning time and maximize the benefits to your career. Like
配列操作の比較表: Ruby, Python, JavaScript, Perl, C++ プログラムを書いていると、他のプログラミング言語の記憶とごっちゃになって、「配列の後ろに要素を追加するのは push だっけ、 append だっけ」などと混乱することがあります。特に Ruby, Python, JavaScript はコードの書き方が似ているので、この問題が起きがちです。 そこで、備忘録として、 Ruby, Python, JavaScript, Perl, C++ の配列操作の比較表を作りました。一番慣れている Ruby を基準にしています。間違いなどがあったらご指摘いただけると助かります。他の言語のもあるといいなあ。 Ruby (Array) Python (list) JavaScript (Array) Perl (@) C++ (std::vector)
