UUID package coming to Go standard library
I would like to suggest the addition to the standard library of a package to generate and parse UUID identifiers, specifically versions 3, 4 and 5. The main reason I see to include it is that the most popular 3rd-party package (github.com/google/uuid) is a staple import in every server/db based Go program, as confirmed by […]
An LLM doesn’t write correct code, it writes plausible code
One of the simplest tests you can run on a database: Doing a primary key lookup on 100 rows. SQLite takes 0.09 ms. An LLM-generated Rust rewrite takes 1,815.43 ms. It’s not a misplaced comma! The rewrite is 20,171 times slower on one of the most basic database operations. The thing is though: The code […]

C# Strings Silently Kill Your SQL Server Indexes in Dapper
I recently spent time digging into a production performance issue. The application was running hot — CPU averaging over 50% and spiking into the 90s. We pulled a diagnostic snapshot and started working through the top queries by CPU time. The number one offender? A straightforward Dapper query. Simple WHERE clause on an indexed column. […]
The Window Chrome of Our Discontent
In a WWDC 2011 session, Dan Schimpf explained some of the goals of the refreshed design for Aqua in Mac OS X Lion were “meant to focus the user attention on the active window content”. This sentiment was echoed by John Siracusa in his review of Lion for Ars Technica: Apple says that its goal […]
this css proves me human
Capitalization is the first wound. It hurts less than I thought it would. The words spill out capitalized, so I must find another way. cat post.md | tr A-Z a-z | sponge post.md is too crude a tool, and my blocks of code must remain inviolate. Careful targeting of text-transform: lowercase is enough. Em dashes. […]

The Shady World of IP Leasing

The addresses got hoarded and the market devolved into a wild sub-leasing economy where anyone can choose where their IPs appear from, who owns them on paper, and scrub them clean of any history. IPv4 ”Exhaustion” is a Myth You’ve heard it a thousand times: we’ve run out […]
