Decision tables are easy, simple, and powerful. You can teach them in five minutes and write one in half that time. You can look at a table and understand what it’s saying, see if it matches your problem, and check for design flaws. So it’s kinda weird that there’s basically nothing about them online. I wrote an…
Beginning August 13th, 2021, we will no longer accept account passwords when authenticating Git operations on GitHub.com.
Longer answer: it depends on what you mean by "equivalent". Pointer arithmetic and array indexing are equivalent. In other aspects, pointers and arrays are different.
Over the past two years, posts on this blog have slowed to just a trickle, and a number of TextMate users have asked about TextMate’s status, or publicly worried about its future. This blog post, the first I’ve written here in a long time, is an attempt to assuage those concerns and answer some of the most frequent…

Hear from a Warp engineer why building a UI in Rust is challenging. Learn about innovative solutions and approaches to tackle its strict memory management and lack of inheritance.
About two weeks ago I entered a discussion with the docs.rs team about, basically, why we have to look at this: When we could be looking at this: And of course, as always, there are reasons why thi...
Extend the switch statement so that it can be used as either a statement or an expression, and that both forms can use either a "traditional" or "simplified" scoping and control flow behavior. These changes will simplify everyday coding, and also prepare the way for the use of pattern matching (JEP 305) in switch …
During a recent audit, we discovered that some third-party Chromium based browsers were able to integrate Google features, such as Chrome sy...
The halting problem asks whether the execution of a specific program for a given input will terminate.
Lately, I’ve been reading articles about best practices for code reviews. I notice that these articles focus on finding bugs to the exclusion of almost every…
I learned a neat tip from my co-worker, Craig Silverstein ( more on Craig joining Khan Academy ), recently and I thought others might find it to be useful.
"Why do you jackasses use these inferior linguistic vehicles when we have something here that’s so precious, so elegant, which gives me so ...
tl;dr: I have created a test suite for comparing the transaction isolation levels in different databases. I did this as background research for my book . This post explains why.

A common perspective is that types are restrictions . Static types restrict the set of values a variable may contain, capturing some subset of the space of “all possible values.” Under this worldview, a typechecker is sort of like an oracle, predicting which values will end up where when the program runs and making…

Compiler Design in C Download a copy! My book Compiler Design in C is now, unfortunately, out of print. You can download a complete copy, with the above button (pdf 19.1Mb OCR/Searchable—thanks to Marvin Hernández for adding the OCR). If you don’t want to print it out (the book is 984 pages long), you can…
I have come to appreciate coding agents to be valuable tools for working with computer program code in any capacity, such as learning about any program’s architecture, diagnosing bugs or developing proofs of concept. Depending on the use-case, reviewing each command the agent wants to run can get tedious and…
The DeWitt clause lets database vendors forbid publishing benchmarks. What the clause is, which vendors still use it, and what you can legally publish.
To provide a secure and dependable experience on GitHub, we’re rolling out updates to rate limits for requests made without authentication. These changes will apply to operations like cloning repositories…
Rust doesn’t have namespaces in its package management system. It’s often viewed as a bug. But it’s not a bug, it’s a feature! While there are negative aspects of a flat package registry, there are also real benefits. Stability, continuity, and unity (discourages forks and fragmented identity)…

In this post we'll discuss the second argument on why the epoll() is broken. The problem is best described in an LWN comment by Foom :
