programming isn't a competition

what is a build system, anyway?

Some definitions and an overview of the world of build systems

I want a better build executor

I want a way to gradually transition existing builds to be hermetic.

I want a better action graph serialization

Makefiles and Ninja files have limitations, separate from the implementing tool. How can we fix them?

negative build dependencies

A build system needs to know not just which files exist, but which shouldn't exist.

brownouts reveal system boundaries

You have backups for your critical data. Do you have backups for your critical infrastructure?

the terminal of the future

To redesign infrastructure, you have to allow incremental adoption, while simultaneously moving the whole design space at once.

an engineer's perspective on hiring

hiring in tech is broken and everyone knows it. what can we do better?

you are in a box

your data is trapped inside the box that is your program. you can only see what the program author exposes.

constrained languages are easier to optimize

exposing raw pointers make the optimizer’s job horribly hard. high level languages can constrain your program, making more optimizations sound.

sorry for the rss screwup

a couple days ago i pushed about 10 empty posts at once to everyone subscribed to my RSS feed. oops. sorry about that. i've since fixed it, but most RSS readers i've seen will cache the posts indefinitely once they're published. the workaround for my own client was to delete my page and then readd it, which will unfortunately discard all your read/unread state. the reason this…

theory building without a mentor

learning how a program is intended to work is hard. here's how to do it.

technical debt is different from technical risk

"technical debt" is about updating your understanding of the program over time. "technical risk" is about sacrificing your ability to make changes for speed of development in the short term.

Scheduling Do-Not-Disturb in GNOME

Do Not Disturb GNOME has a little button that lets you turn on Do-Not-Disturb for notifications: Unfortunately, it has no way of scheduling DnD . Good news, though! It does support turning on DnD through the CLI: gsettings set org.gnome.desktop.notifications show-banners false . I put that in a script named toggle-dnd in my dotfiles: $ cat bin/toggle-dnd # !/bin/sh case $ { 1 :- }…

the rust project has a burnout problem

the number of people who have left the rust project due to burnout is shockingly high. the number of people in the project who are close to burnout is also shockingly high. this post is about myself, but it's not just about myself. i'm not going to name names because either you know what i'm talking about, in which case you know at least five people matching this description, or you…

I'll Rust With You: the song

I'll Rust With You: the song Niko Matsakis, co-lead for the Rust language team, recently published a song titled "Edition: the song" . I decided I was not to be outdone and sang a cover of "I'll Rust With You", by Steam Powered Giraffe . The song has absolutely no relation to the Rust language other than the title, I just think it's fun. Video
