Revisiting a 'smaller Rust'
A bit over a year ago, I wrote some notes on a “smaller Rust” - a higher level language that would take inspiration from some of Rust’s type system innovations, but would be simpler by virtue of targeting a domain with less stringent requirements for user control and performance. During my time of unemployment this…

Ideology
Some people claim that unit tests make type systems unnecessary: "types are just simple unit tests written for you, and simple unit tests aren't the important ones". Other people claim that type systems make unit tests unnecessary: "dynamic languages only need unit tests because they don't have type systems." What's…

PEP 557 – Data Classes
This PEP describes an addition to the standard library called Data Classes. Although they use a very different mechanism, Data Classes can be thought of as “mutable namedtuples with defaults”. Because Data Classes use normal class definition syntax, y...

A Plan for Spam
August 2002 (This article describes the spam-filtering techniques used in the spamproof web-based mail reader we built to exercise Arc . An improved algorithm is described in Better Bayesian Filtering .) I think it's possible to stop spam, and that content-based filters are the way to do it. The Achilles heel of the…

What science can tell us about C and C++'s security
There are not a lot of very strong empirical results in the field of programming languages . This is probably because there’s a huge amount of variables to control for, and most of the subjects available to researchers are CS undergraduates. However, I have recently found a result replicated across numerous codebases…

Performance is a Feature
We’ve always put a heavy emphasis on performance at Stack Overflow and Stack Exchange. Not just because we’re performance wonks (guilty!), but because we think speed is a competitive advantage. There’s plenty of experimental data proving that the slower your website loads and displays, the less people

The largest Git repo on the planet
It’s been 3 months since I first wrote about our efforts to scale Git to extremely large projects and teams with an effort we called “Git Virtual File System”. As a reminder, GVFS, together with a set of enhancements to Git, enables Git to scale to VERY large repos by virtualizing both the .git folder […]

Tail Call Optimisation in Common Lisp Implementations
While the Common Lisp standard does not require implementations to eliminate tail calls, some do—thereby allowing a more functional programming style. Especially in the prototyping phase, it can be useful to know where this functional style can be employed and where it's likely to cause stack overflow. Since I…

A Guide to Branching in Mercurial / Steve Losh
I've been hanging out in the #mercurial and #bitbucket channels on freenode a lot lately, and I've noticed a topic that comes up a lot is "how does Mercurial 's branching differ from git 's branching?"
