Performance comparison: counting words in Python, Go, C++, C, AWK, Forth, and Rust March 2021 Summary: I describe a simple interview problem (counting frequencies of unique words), solve it in various languages, and compare performance across them. For each language, I’ve included a simple, idiomatic solution as well as a more optimized approach via profiling. Go to: Constraints | Python Go C++ C
プログラミング言語「Ruby」の国内最大のビジネスカンファレンス「RubyWorld Conference」。Rubyの先進的な利用事例や最新の技術動向、開発者教育の状況などの情報を発信することで、「Rubyのエコシステム(生態系)」を知ることができる場として開催します。ここで登壇したのは、Rubyアソシエーション 理事長のまつもとゆきひろ氏。プログラミング言語の過去、歴史から学ぶ教訓について発表しました。全4回。2回目は、「単純さはいつも最高ではない」と「大きいことはいつもいいことではない」について。前回はこちら。 単純さはいつも最高ではない まつもとゆきひろ氏：「最も単純なプログラミング言語は何ですか？」という質問をするとですね……文法的にという意味なんですけども。 初期の言語として、Lisp、FORTH、APLなど、みんな1960年代ぐらいに作られた言語ですが、こういうものが挙げられ

WHAT This program is called: "A tool for exploring sound as pure form." or "sound as pure form" or "sapf" It is an interpreter for a language for creating and transforming sound. The language is mostly functional, stack based and uses postfix notation similar to FORTH. It represents audio and control events using lazy, possibly infinite sequences. It intends to do for lazy sequences what APL does
厚生労働省検疫所「FORTH」、海外で健康に過ごすために。
Hello, my name is Virgil Dupras, author of Collapse OS and Dusk OS and I'm starting a series of articles that aims to hand-hold my former self, a regular web developer, into the rabbit hole leading to the wonderful world of low level programming. Hopefully, I can hand-hold you too. The general goal is to broaden your perspectives on the subject of computing. I intend do to that through story arcs
ナタリー 音楽 特集・インタビュー BABYMETAL BABYMETAL「METAL FORTH」インタビュー｜本格的な海外進出、日本への思い BABYMETAL「METAL FORTH」 PR 2025年8月8日 BABYMETALが8月8日、4thアルバム「METAL FORTH」を全世界同時にリリースした。 ワールドワイドな活動をさらにパワーアップさせるため、BABYMETALはアメリカに活動拠点となる会社「BABYMETAL WORLD LLC」を設立。ハリウッドに本社を置くキャピトル・レコードとグローバルレーベルパートナー契約を締結した。 本格的な海外進出の狼煙を上げるニューアルバムは、BABYMETALがこれまでの活動を通して出会った世界各地のアーティストとのコラボ曲を多数収めた作品。豪華アーティストが、“メタルのその先へ”を示すアルバムを鮮やかに彩っている。 音楽ナタリーで
This Forth interpreter, entirely written as bash script, is a F³ (Fully Functional Forth), albeit a tad slow. Some would call it "sluggish". As rough indication, an ARM SBC which I'm running Bashforth on takes about 15 second for an empty loop of 100,000 iterations. It has built-in doc and see facilities, simplifying exploration of Bashforth. Bashforth lacks floating point support and vocabularies

On a recent rainy afternoon, [Thanassis Tsiodras] decided to build his own Forth for the Arduino to relieve the boredom. One week of intense hacking later, he called it done and released his project as MiniForth on GitHub. [Thanassis] says he was inspired by our series of Forth articles from a few years back, and his goal was to build a Forth interpreter / compiler from scratch, put it into a Blue
Overview Konilo is a small, pragmatic personal computing system written in Forth and running on a tiny virtual computer. A complete system consists of an ilo vm, an image file ("rom") with the Konilo system, and a set of blocks for storage of code and data. Features dual stack architecture 64k cells of word addressed (32-bit) memory 30 instructions, four instructions per word block based data stor
If you like Forth, but find it challenging to build real stuff with, Factor (https://factorcode.org/) is most or all of the good stuff about Forth designed in a way that's much easier to do things with. It was designed by Slava Pestov (who I think had a big hand in Swift), and honestly it's a lot of fun to build webapps and other programs with, and much less brutal to read than Forth can be. I had
I first ran into Forth about 20 years ago when reading a book about designing embedded hardware. The reason I got the book back then was to actually learn more about the HW aspects, so having skimmed the Forth chapter I just registered an "oh, this is neat" mental note and moved on with my life. Over the last two decades I heard about Forth a few more times here and there, such as that time when F
Fitting a Forth in 512 bytes June 10, 2021 · 31 minute read This article is part of the Bootstrapping series, in which I start from a 512-byte seed and try to bootstrap a practical system. Software is full of circular dependencies if you look deep enough. Compilers written in the language they compile are the most obvious example, but not the only one. To compile a kernel, you need a running kerne

(Image of "Four-Armed Chuck" programming a PDP-11 is from my giant write-up of Forth.) I’ve made a couple Forths. Not a single one of them are "finished software" intended for industrial use, but all of them taught me something about Forth, concatenative programming, and how computers work in general. Sure, I’ve done my time in that place where points are free and the stacks always need twiddling.
ｃonstexpr関数はコンパイル時処理。これはいい。実行時が霞んで見える。cpuの嬌声が聞こえてきそうだ
( Wrote a blog post about this here ) It was raining hard, a week ago. And what could you possibly do on a rainy Saturday afternoon? Well... You can make a Forth interpreter/compiler from scratch... ...then put it inside a 1.5$ Blue Pill microcontroller... ...and finally, inside an Arduino UNO... ... within its tiny 2K RAM! Click on the image to watch it blinking the LED of my Arduino: I haven't d
