Keeping two or more copies of the same document synchronized with each other in real-time is a complex challenge. This paper describes the differential synchronization algorithm. Differential synchronization offers scalability, fault-tolerance, and responsive collaborative editing across an unreliable network.
Due to a variety of technical and organizational issues, we will be sunsetting React Native and putting all of our efforts into making…
A recent paper suggested a new mathematical point of view on version control. I first found out about it from pijul, a new version control system (VCS) that ...
The text in these files is the unedited original manuscript. M-K has fine copy editors, who have fixed all the minor typos, spelling, and grammar errors in the printed book, but if you come across factual errors I'd still appreciate help getting all the details of linking and loading as complete and correct as…
Is IEEE floating-point math deterministic? Will you always get the same results from the same inputs? The answer is an unequivocal “yes”. Unfortunately the answer is also an unequivocal “no”. I’m a…
People call WebAssembly a game changer because it makes it possible to run code on the web faster. Some speedups are already present, and some are yet to come. With ...
At Mozilla, we want WebAssembly to be as fast as it can be. This started with its design, which gives it great throughput. Then we improved load times with a ...
This summer, I am again working on Rust full-time, and again I will work (amongst other things) on a “memory model” for Rust/MIR. However, before I can talk about the ideas I have for this ...
Disclaimer 2024-12-02 Since this rant is going viral again (again (again)), some disclaimers: I wrote this six years ago to “”“win”“” an ugly Twitter fight. I’m glad I anonymized the inciting tweet and hope I’m the only person still getting grief over this. The core interesting bit— why it’s mathematically valid to…
The Apple Macintosh combined brilliant design in hardware and in software. The drawing program MacPaint, which was released with the computer in January of 1984, was an example of that brilliance both in what it did, and in how it was implemented.
The Game Engine Black Book Wolfenstein 3D, 2nd Edition has shipped. It is available at the following locations: - Amazon ( US , UK , FR , CA , and many more). - Google PlayStore ( here ). All errata which readers kindly took the time to report have been addressed. Adrian Carmack has retired from anything related to id…
On 14 May 2018, Sebastiano Vigna added a page to his website (archived here) entitled “The wrap-up on PCG generators” that attempts to persuade readers to avoid various PCG generators. That day, he al
There are many greplike tools available to choose from. ripgrep is currently the fastest, which folks seem to focus on, but they have different features. Here's a chart to help you see which tools can do what.
Today, we're extending Cloudflare Workers with support for WebAssembly. All Workers customers can now augment their applications with WASM at no additional cost.
This document is an attempt to be a fairly comprehensive guide to recovering from what you did not mean to do when using git. It isn't that git is so complicated that you need a large document to take care of your particular problem, it is more that the set of things that you might have done is so large that different…
In this post I want to explore the costs of threads on modern Linux machines, both in terms of time and space. The background context is designing high-load concurrent servers, where using threads is one of the common schemes .
Today we’ll be looking at how to connect the protocols powering Mastodon in the simplest way possible to enter the federated network. We will use static files, standard command-line tools, and some simple Ruby scripting, although the functionality should be easily adaptable to other programming languages. First…
We’ve teamed up with Google Cloud Platform – here’s what that means for you.
Let me preface this with an apology: this is a technology love story, and as such, it’s long, rambling, sentimental and personal. Also befitting a love story, it has a When Harry Met Sally feel to it, in that its origins are inauspicious…
I’m building a toy HTML rendering engine, and I think you should too. This is the first in a series of articles:
October 1997: It has been six years since I finished Paradigms of AI Programming (or PAIP ), and now seems like a good time to look back at how Lisp and AI programming have changed.
The vast majority of my posts about random number generation have focused on looking at the properties of different generation schemes. But, perhaps surprisingly, the performance of your randomized a
Protobuf, the binary format crafted by Google, surpasses JSON performance even on JavaScript environments like Node.js/V8 and web browser...
Find out what kinds of automated tests you should implement for your application and learn by examples what these tests could look like.
We can admit our knowledge gaps without devaluing our expertise.
Pipenv is a Python packaging tool that does one thing reasonably well — application dependency management. However, it is also plagued by issues, limitations and a break-neck development process. In the past, Pipenv’s promotional material was highly misleading as to its purpose and backers.
Since we originally proposed the need for a first-class language, compiler and ecosystem for machine learning (ML), there have been plenty of interesting developments in the field. Not only have the tradeoffs in existing systems, such as TensorFlow and PyTo...
