GitHub - susam/emfy: A dark and sleek Emacs setup for general purpose editing and programming
Are you an absolute beginner to Emacs? Are you so new to Emacs that you do not even have ~/.emacs.d on your file system? Have you come across recommendations to use starter kits like Doom Emacs, Spacemacs, etc. but then you wondered if you could use vanilla Emacs and customize it slowly to suit your needs without having to sacrifice your productivity in the initial days of using Emacs? Do you also
Filippo Valsorda 31 March 2022 Modern software engineering is collaborative, and based on reusing Open Source software. That exposes targets to supply chain attacks, where software projects are attacked by compromising their dependencies. Despite any process or technical measure, every dependency is unavoidably a trust relationship. However, the Go tooling and design help mitigate risk at various
A recent article on WebAssembly Garbage Collection (WasmGC) explains at a high level how the Garbage Collection (GC) proposal aims to better support GC languages in Wasm, which is very important given their popularity. In this article, we will get into the technical details of how GC languages such as Java, Kotlin, Dart, Python, and C# can be ported to Wasm. There are in fact two main approaches:

You may be aware of Nix or NixOS. Users love them for being superior tools for building, deploying, and managing software. Yet, Nix is generally perceived as notoriously hard to learn. The core Nix ecosystem consists of several distinct components: Nix is a build system and package manager that comes with a configuration language to declare software components, the Nix language.

This tutorial introduces the basics of generics in Go. With generics, you can declare and use functions or types that are written to work with any of a set of types provided by calling code. In this tutorial, you’ll declare two simple non-generic functions, then capture the same logic in a single generic function. You’ll progress through the following sections: Create a folder for your code. Add n

Introduction to Go 1.15 The latest Go release, version 1.15, arrives six months after Go 1.14. Most of its changes are in the implementation of the toolchain, runtime, and libraries. As always, the release maintains the Go 1 promise of compatibility. We expect almost all Go programs to continue to compile and run as before. Go 1.15 includes substantial improvements to the linker, improves allocati
Jean de Klerk, Matt T. Proud 24 February 2021 Introduction In many Go APIs, especially modern ones, the first argument to functions and methods is often context.Context. Context provides a means of transmitting deadlines, caller cancellations, and other request-scoped values across API boundaries and between processes. It is often used when a library interacts — directly or transitively — with rem

Across these repos, the savings average around 75%, but memory reductions are non-linear: as projects get larger, so does the relative decrease in memory usage. We’ll explain this in more detail below.

Introduction HTML, the programming language, is a practical, turing-complete[1], stack-based programming language based on HTML, the markup language. It uses elements defined in HTML, the markup language, in order to do computations. To give you a sense of what HTML, the programming langauge, looks like, below is a sample program that prints the values from 1 to 10 to standard out (console.log) A

Why Python is not the programming language of the future

【レビュー】11/1発売の低年齢向けプログラミング教育用ボードゲーム「COOL PROGRAMMING」の感想を1万字でしっかり書いてみた - ボードゲーム好き夫婦の楽しい毎日
こんにちは。今日はプログラミング教育用ボードゲーム「クールプログラミング」の感想を書いていきたいと思います！ 2020年から義務教育にプログラミング教育が入ってくるというのは、かなり前から話題ですが、英語ならまだしも、親世代で未経験の人も多いプログラミング教育の導入には、戸惑われている親御さんも多いのではないでしょうか。 どうやって子どもにプログラミングの素養を持たせたらいいのか…？ そもそもプログラミングの素養って何…？ そんな疑問の声も聞こえてきそうですね。 そこで、今回は、プログラミングも（そこそこ）できてボードゲーム好きの筆者が2019年11月1日発売の、6歳からプログラミングが学べるボードゲーム教材についてレビューしていきたいと思います！ 注：本ブログのメイン読者であるボードゲーマーさん向けに先に一言いうと、プレイ感はハイパーロボに近いです ～こんな記事もかいています～ まだ資本

When I first learned Python nearly 27 years ago, I was immediately struck by how I could productively apply it to all sorts of messy work projects. Fast-forward a decade and I found myself teaching others the same fun. The result of that teaching is this course--A no-nonsense treatment of Python that has been actively taught to more than 400 in-person groups since 2007. Traders, systems admins, as

GitHub - lovasoa/bad_json_parsers: Exposing problems in json parsers of several programming languages.
Many JSON parsers (and many parsers in general) use recursion to parse nested structures. This is very convenient while programming the parser, but it has consequences on what the parser can parse: indeed, the size of the call stack is usually limited to a value several orders of magnitude smaller than the available RAM, and this implies that a program with too many levels of recursion will fail.

Lately I’ve been messing around with Python 3.12, discovering new features around typing and pattern matching. Combined with dataclasses, they provide support for a style of programming that I’ve employed in Kotlin and Typescript at work. That style in turn is based on what I’d do in OCaml or Haskell, like modelling data with algebraic data types. However, the more advanced concepts from Haskell —

In 2013, I had an idea: "what if I were to build my programming language?". Back then my idea came down to "an interpreted language that mixes elements from Ruby and Smalltalk", and not much more. Between 2013 and 2015 I spent time on and off trying different languages (C, C++, D and various others I can't remember) to see which one I would use to build my language in. While this didn't help me fi
The Go Blog Finding unreachable functions with deadcode Alan Donovan 12 December 2023 Functions that are part of your project’s source code but can never be reached in any execution are called “dead code”, and they exert a drag on codebase maintenance efforts.
