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.
I’ve often thought that software developers were akin to Magpies, birds notorious for stealing shiny items to decorate their complex nests. Like Magpies, software developers are unusually smart and curious creatures, almost by definition. But we are too easily distracted by shiny new toys and playthings. I no longer
Slides and video from my talk "Domain Modeling Made Functional with the F# Type System"
A common problem I see in object-oriented design is: A wizard is a kind of player. A warrior is a kind of player. A staff is a kind of weapon. A sword is a kind of weapon. A player has a weapon. Bu…
You are seeing this because the administrator of this website has set up Anubis to protect the server against the scourge of AI companies aggressively scraping websites . This can and does cause downtime for the websites, which makes their resources inaccessible for everyone.

Update 2014.12.17: Now that SSL is encouraged for everyone and doesn’t have performance concerns , this technique is now an anti-pattern . If the asset you need is available on SSL, then always use the https:// asset.
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 ...
A while back I did a series of postings on the topic of Common Misconceptions About Publishing.
Explaining the Dependency Injection pattern, by contrasting it with Service Locator. The choice between them is less important than the principle of separating configuration from use.
An introduction to the idea that code should be approached with a mindset towards compressing it semantically, rather than orienting it around objects.
(This post is an aspirational transcript of the talk I gave to the Data Terra Nemo conference in May 2015. If you’d like to watch the less eloquent version of the same talk that I actually gave, the video should be available soon!)
From heat guns to kernel compiler flags
It happened. Nearly 5 years of paper writing, being snuck Committee Meeting notes on the DL until I could access them myself and absolve my co-conspirators of their sins, 5 different implementations/patches later, I can
After a temporary stay in Japan to focus on my health and personal responsibilities, I am fully recovered, ready, and excited to work abroad again.
Oh, Steve, you do make me laugh, always. And it's so long between posts these days I hardly believed it when Safari hinted that there was some action over at Steve's. Thank you.
It’s well-known at this point that GPT-4/GPT-3.5-turbo is non-deterministic, even at temperature=0.0. This is an odd behavior if you’re used to dense decoder-only models, where temp=0 should imply greedy sampling which should imply full determinism, because the logits for the next token should be a pure function of…
Internet debates about typing disciplines continue to be plagued by a pervasive myth that dynamic type systems are inherently better at modeling “open world” domains. The argument usually goes like this: the goal of static typing is to pin everything down as much as possible, but in the real world, that just isn’t…
The ‘Unix philosophy’ originated with Ken Thompson's early meditations on how to design a small but capable operating system with a clean service interface. It grew as the Unix culture learned things about how to get maximum leverage out of Thompson's design. It absorbed lessons from many sources along the way.
This is a loose transcript (or long paraphrasing?) of a presentation given at ConnectDev'16, a conference organized by Genetec in which I was invited to speak.
Commit messages matter. Here's how to write them well.
Some time ago, I wrote a blog post about how there’s more to a pointer than meets the eye. One key point I was trying to make is that just because two pointers point to the same address...
In this document, I describe what is, in my humble but correct opinion, the best known algorithm for threading messages (that is, grouping messages together in parent/child relationships based on which messages are replies to which others.) This is the threading algorithm that was used in Netscape Mail and News 2.0…
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…
Introduction Hi, I’m Glenn Fiedler and welcome to Game Physics. In the previous article we discussed how to integrate the equations of motion using a numerical integrator. Integration sounds complicated, but it’s just a way to advance the your physics simulation forward by some small amount of time called “delta time”…
