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

From Wikipedia: A Forth environment combines the compiler with an interactive shell, where the user defines and runs subroutines called words. Words can be tested, redefined, and debugged as the source is entered without recompiling or restarting the whole program. All syntactic elements, including variables and basic operators are defined as words. Forth environments vary in how the resulting pro

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
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
Forth: The programming language that writes itself: The Web Page Author: Dave Gauer Created: 2023-02-02 Updated: 2024-12-22 Note: This page is my personal journey to discover Forth and put it in the context of computing history. It is adapted from my slides for a short talk. I've done everything in my power to make this page scale up and down for various screen sizes. I welcome suggestions and cor
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
Fitting a Forth in 512 bytes June 10, 2021 · 39 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
11. 謎の⾔語、Forth 2/5 典型的なForth の実装には、LISP におけるRead–eval–print loop（英語版）（REPL）に対応する、⼊⼒されたワードを即 座に実⾏する対話型のインタプリタモードと（これは、正規 のオペレーティングシステムがないシステム向けのシェルに も適している）、後の実⾏のために⼀連のワードをコンパイ ルするモードのふたつのモードがある。後者にはコロン（:） というワードにより遷移しセミコロン（;）というワードで脱 する。 ─ 『Forth』, Wikipediaより
( 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
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
