Helpful background for code reading The GNU coreutils has its foibles. Many of these utilities are approaching 30 years old and include revisions by many people over the years. Here are some things to keep in mind when reading the code: Tiny programs - These utilities are small, (mostly) single-source file programs designed to do one thing and do it well. They are not designed for long life or to

Parsing SQL - Strumenta
The code for this tutorial is on GitHub: parsing-sql SQL is a language to handle data in a relational database. If you worked with data you have probably worked with SQL. In this article we will talk about parsing SQL. It is in the same league of HTML: maybe you never learned it formally but you kind of know how to use it. That is great because if you know SQL, you know how to handle data. However
Posted on Tuesday, April 2, 2024. Updated Wednesday, April 3, 2024. Introduction Andres Freund published the existence of the xz attack on 2024-03-29 to the public oss-security@openwall mailing list. The day before, he alerted Debian security and the (private) distros@openwall list. In his mail, he says that he dug into this after “observing a few odd symptoms around liblzma (part of the xz packag
Over the course of my Spring 2020 semester at Harvey Mudd College, I developed a self-hosting compiler entirely from scratch. This article walks through many interesting parts of the project. It’s laid out so you can just read from beginning to end, but if you’re more interested in a particular topic, feel free to jump there. Or, take a look at the project on GitHub. Table of contents What the pro

SectorC: A C Compiler in 512 bytes SectorC (github) is a C compiler written in x86-16 assembly that fits within the 512 byte boot sector of an x86 machine. It supports a subset of C that is large enough to write real and interesting programs. It is quite likely the smallest C compiler ever written. In a base64 encoding, it looks like this: 6gUAwAdoADAfaAAgBzH/6DABPfQYdQXoJQHr8+gjAVOJP+gSALDDqluB+9
Introduction The story behind this article is very simple, I wanted to learn about new C++20 language features and to have a brief summary for all of them on a single page. So, I decided to read all proposals and create this “cheat sheet” that explains and demonstrates each feature. This is not a “best practices” kind of article, it serves only demonstrational purpose. Most examples were inspired
Summary Introduce virtual threads to the Java Platform. Virtual threads are lightweight threads that dramatically reduce the effort of writing, maintaining, and observing high-throughput concurrent applications. This is a preview API. Goals Enable server applications written in the simple thread-per-request style to scale with near-optimal hardware utilization. Enable existing code that uses the j
Note: this article is available as an ebook and as a printed book for easier reading Introduction What is this? When I was first learning Go, I already knew several other programming languages. But after reading an introductory book and the language specification I felt like I really didn’t know enough about Go to use it for real world work. I felt I’d probably need to fall into many traps before
Try Mastering Emacs for free! Are you struggling with the basics? Have you mastered movement and editing yet? When you have read Mastering Emacs you will understand Emacs. It’s that time again: there’s a new major version of Emacs and, with it, a treasure trove of new features and changes. Notable features include the formal inclusion of native compilation, a technique that will greatly speed up y
Type Parameters Proposal
Ian Lance Taylor Robert Griesemer August 20, 2021 StatusThis is the design for adding generic programming using type parameters to the Go language. This design has been proposed and accepted as a future language change. We currently expect that this change will be available in the Go 1.18 release in early 2022. AbstractWe suggest extending the Go language to add optional type parameters to type an
V8 Torque is a language that allows developers contributing to the V8 project to express changes in the VM by focusing on the intent of their changes to the VM, rather than preoccupying themselves with unrelated implementation details. The language was designed to be simple enough to make it easy to directly translate the ECMAScript specification into an implementation in V8, but powerful enough t

Cosmo goes beyond securing individual endpoints; it offers a comprehensive platform for managing and federating APIs with built-in security features, performance optimizati
Updated 2024-09-17 to reflect updated PgBouncer support for protocol-level prepared statements 🐘 To start, I want to say that I’m appreciative that PgBouncer exists and the work its open source maintainers put into it. I also love working with PostgreSQL, and I’m thankful for the incredible amount of work and improvements that go into it as well. I also think community and industry enthusiasm aro
Django for Startup Founders: A better software architecture for SaaS startups and consumer apps
In an ideal world, startups would be easy. We'd run our idea by some potential customers, build the product, and then immediately ride that sweet exponential growth curve off into early retirement. Of course it doesn't actually work like that. Not even a little. In real life, even startups that go on to become billion-dollar companies typically go through phases like: Having little or no growth fo
