Mastodon: 15 Accounts¶

Social feeds are a controlled poison. Used well, they give you a running commentary from the sharpest working engineers in the field. Used badly, they replace the deep work that gets you good. This file lists 15 accounts, split across X, Bluesky, and Mastodon (many engineers migrated post-2023), all verified active in mid-2026. Follow them, then mute the algorithm.

The 15 to follow¶

#	Person	Role	Primary handle (mid-2026)	Why follow
1	Chris Lattner	Creator of LLVM/Clang/Swift/Mojo	X: `@clattner_llvm`	Compiler internals, career takes, occasional Mojo/Swift-vs-C perspective
2	Bryan Cantrill	Oxide Computer CTO, illumos, DTrace	X: `@bcantrill` · Mastodon: `@bcantrill@mastodon.social`	Systems-industry commentary. The “Fork Yeah!” of tweets.
3	Julia Evans	Author, jvns.ca, Wizard Zines	Bluesky: `@b0rk.jvns.ca` · Mastodon: `@b0rk@jvns.ca`	Best “how does this actually work” explainer alive
4	Chris Wellons	Author, nullprogram.com	Mastodon: search `nullprogram`	Occasional but every post reciprocates a blog post you’d want to read
5	Salvatore Sanfilippo (antirez)	Creator of Redis	X: `@antirez` · blog: `antirez.com`	Opinionated systems takes; recently on AI + coding
6	Georgi Gerganov (ggerganov)	Creator of llama.cpp, ggml	X: `@ggerganov` · GitHub: `@ggerganov`	Real-time updates on the most important C project of the AI era
7	Fabrice Bellard	Creator of QEMU/FFmpeg/TCC	Does not use social media meaningfully	Follow him via bellard.org RSS instead
8	Brendan Gregg	Performance engineer, Intel	X: `@brendangregg` · Bluesky: `@brendangregg.com`	Perf, flame graphs, eBPF
9	Andrei Alexandrescu	Author, Modern C++ Design	X: `@incomputable`	C++ mostly but low-level allocator and memory-model takes carry to C
10	Dan Luu	Blogger, danluu.com	Mastodon: `@danluu@mastodon.social` · X: `@danluu`	Data-driven systems and career takes
11	Casey Muratori	Handmade Hero, Computer Enhance	X: `@cmuratori`	Performance-first programming ethos
12	Michael Kerrisk	Author, The Linux Programming Interface, man7.org	X/Mastodon presence limited; follow via man7 mailing list	Definitive Linux programming voice
13	Linus Torvalds	You know	Does not use social; read via LKML	Skip social; read his LKML replies
14	JeanHeyd Meneide (ThePhD)	WG14/WG21 committee member	Bluesky/Mastodon: search `thephd` · blog: `thephd.dev`	Deep C/C++ standards work, C23 defer, `checked_return`, etc.
15	Aleksey Shipilëv	JVM perf, memory-model authority	Mastodon: `@shipilev@mastodon.online`	Memory-model articles apply directly to C11 atomics

Platform notes (as of mid-2026)¶

X (Twitter): still where most working programmers post day-to-day, though the SNR has dropped. Use lists, not the algorithmic feed.
Bluesky: growing rapidly; the “tech Twitter of 2018” vibe. Wellons, Julia Evans, and several Zoho engineers are here.
Mastodon: slower but higher-signal. mastodon.social, hachyderm.io, and fosstodon.org are the C-adjacent instances.
LinkedIn: career only. Do not follow engineers there for technical content.

How to build a low-poison feed¶

Follow exactly the 15 above (or subset) on one platform.
Turn off retweets/reposts globally.
Use lists — put the 15 in a “C Systems” list, and read the list, not the home timeline.
Set a 20-min/day budget. Time-box in a real timer.
Quarterly audit: any account you didn’t get value from, unfollow.
