In my study of keyboarding in the past 20 years, i've noticed that the choices of many shortcuts in many apps are adopted to the many aspects of the keyboard hardware of the time in use by the community. Emacs's keybinding is not simply based on the first letter of commands, but the QWERTY layout's key positions have…
Natural language is a wonderful interface, but just because we suddenly can doesn't mean we always should.

This week I built datasette-ripgrep—a web application for running regular expression searches against source code, built on top of the amazing ripgrep command-line tool. datasette-ripgrep demo I’ve deployed a demo …
I’ve been saying for years that it’s bad security advice, that it encourages poor passwords. Lorrie Cranor, now the FTC’s chief technologist, agrees: By studying the data, the researchers identified common techniques account holders used when they were required to change passwords. A password like “tarheels#1”, for…
How I secured a ThinkPad: a Windows honeypot with Prey for thieves, TRESOR against cold boot, a USB boot stick for evil maids, and a separate Firefox user.
The other weekend I took some time to play around with the DigitalOcean API, and this is what resulted. The DigitalOcean indicator allows you to monitor and manage your droplets directly from your panel. You can: Quickly see which droplets are active. Reboot, power on, and/or power down you …
When we first started porting Chrome away from just Windows, we intended to use Scons to build Chrome on all our platforms. But early on in development I discovered that Scons, despite its admirable goals of correctness and ease of use, was quite slow — it could take 40 seconds from starting Scons before it decided to…

2025 update v2: I made a tool that fixes distortions introduced by Intel GPA, and that tool made few sections of this blog obsolete. As such, they’ve been deleted. Old version is still available here.2025 update. This blog post now also exists as a youtube video. Yes, the video is 1 hour 20, so about twice as long as…
All of the data in this page is derived from these tests , so is true by some definition of true. Notable is this test - given an arbitrary SQL statement, it determines via runtime inspection which locks are taken.
