Reducing logging cost by two orders of magnitude using CLP
Long, long ago, the amount of data our systems output to logs was small enough that we were able to retain all of the log files. This allowed our engineers to freely analyze the logs, say for troubleshooting our systems or improving applications. But as Uber's business grew rapidly, the amount of data being logged…

We Need New Motherboards Before GPUs Collapse Under Their Own Gravity
You can’t have a 4-slot GPU. You just can’t. We have finally left sanity behind, with nvidia’s 4000 series cards yielding a “clown car” of absurd GPU designs, as GamersNexus put it. These cards are so huge they need “GPU Support Sticks”, which are an actual real thing now. The fact that we insist on relegating the GPU…

An X11 apologist tries Wayland
I think it’s only fair to call me an X apologist. I get incredibly frustrated when people talk about dropping support for X11. I fight back against the notion that some day X11 will be dead and unmaintained, a curiosity of a time before. I’ve spoken to people in my circles at-length about the accessibility tools that…
