tuning a custom proxy on a single ARM64 core and hitting a pretty bad throughput wall my framing benchmarks look fine encode is around 12.8 GB/s with 1 alloc and round trip sits at about 4.3 GB/s with 2 allocs but once it hits the muxer it just drops hard…

Hey everyone, I wrote a post about something I see trip people up a lot: naive HTTP retries. Usually, we just throw a for loop and a time.Sleep() at a failing API call and move on. But that standard approach secretly causes a lot of headaches in Go.…

I built this in Go because my ISP kept blaming me for drops I couldn't prove. Internet Monitor runs in the background and does TCP + HTTP + DNS checks simultaneously, logging every disconnection with its cause and how long it lasted.…

I built GoDaily (https://godaily.dev) after getting bored of piecing together Go news from a dozen sources every morning (part of my job). So I built GoDaily, a free weekday newsletter that pulls from 20+ sources (blogs, Reddit, HN, GitHub releases, Go…

How do I setup to use generic methods with gc and gopls? I have already installed gotip and ran gotip download. I installed gopls@latest using gotip install. Now I wanna use that gopls binary in Neovim.…

Somewhat new to Go, so please be patient... I had a bug that arose from failing to check the error returned from a function call, so ran a linter to see where else I might be doing that.…

Wrote up a deep dive on going from 0.75 GB/s to 49 GB/s scanning a 4 GB file in Go on Linux: a 66× speedup over the initial os.ReadFile. Covers chunked reads, mmap (with all the page-fault footguns), parallel pread, hand-written AVX2 asm, and Go 1.26's…

I've been running YAP in production for a few years to package software across several distros. Cleaned it up enough to share. You write one PKGBUILD and it builds native packages for Debian, Fedora, Alpine, Arch and others.…
