Perforce are starting to ask communities for input for next year's "State of Open Source Report" (In partnership with @osi and @EclipseFdn).

A warning: The results are usually gated behind a form requesting a lot of personal details (with lacking justification), and they previously performed a copyright takedown against me when I attempted to directly share the results with others:

If you publish any #OpenSource and you want people to use it, may I please implore you to test your README?

Can you actually follow the steps you've written down? Does it work if the user doesn't have the same development packages installed as you?

I'm pleased to announce the official release of my book, Refactoring English. I've spent the past two years capturing all the techniques for improving my writing that I've learned over the course of my career as a developer.

Hacking the Go compiler to efficiently map IPv4 to IPv6: https://vincent.bernat.ch/en/blog/2026-go-netip-addrto6. This post digs in how to modify the Go compiler to reduce netip.AddrFrom16()+netip.As16() to almost nothing, first through the noding process, then with rewrite rules for the SSA form.

I'm looking for work, please boost!

I'm a software engineer with 35 years of experience. I've worked across an unusually wide range of domains: mobile game backends, privacy-preserving data platforms, high-throughput COVID testing infrastructure, email and account systems, e-payment processing, job marketplace systems, and bioinformatics. I pick up new domains quickly and have a history of doing it repeatedly. I understand how to turn business needs into engineering requirements.

I prefer to work remotely but I am open to an in-office job in the Philadelphia area or especially in Philadelphia itself. I've often worked remotely since the 1990s and can operate with minimal supervision. Several of my favorite projects were self-directed: I identified the need, built the thing, and shipped it. My preferred time zone is America/New_York, but I'm flexible.

Some of the many, many technologies I've used are: Python, Perl, TypeScript/JavaScript, Haskell, Go, C, Java. Postgres, MySQL, SQLite. Flask, SQLAlchemy. AWS (Lambda, S3, RDS, SQS, EC2). Docker, Git. Github and Gitlab.

I've also repeatedly picked up new languages and stacks as needed: Haskell for differential privacy research, TypeScript for a 24/7 AWS Lambda system, Flask for my most recent employer. I've become productive with new systems over and over, and I can do it quickly.

I'm a published author (Higher-Order Perl, Morgan Kaufmann), longtime blogger, and conference speaker with a reputation for making complex ideas clear.

I am a U.S. citizen.

Bot-free self-hosted analytics with GoatCounter on NixOS: https://vincent.bernat.ch/en/blog/2026-goatcounter. With an alternative JavaScript client, a fallback to CSS, an overdoing local proxy, and a lot of NixOS, including Litestream to backup an SQLite database!

I decided to offer a print copy of my book and am more excited about it than I expected https://mtlynch.io/retrospectives/2026/09/

New, exclusive (and cathartic), from me:

The consumer data broker Radaris.com has long had a reputation for ignoring requests to remove personal information from its vast empire of people-search services online. That reputation caught up with the company recently in a lawsuit alleging Radaris violated a New Jersey privacy law that provides for hefty fines against data brokers that publish personal information on state law enforcement officials. In the face of repeated stonewalling and prevarication by attorneys for Radaris, the judge in the case ordered that radaris.com and more than a dozen other data broker domains be transferred to the plaintiffs.

I've been reading the digital version of @lcamtuf 's new book but it was fun to get the hardcover in the mail this week

Interesting to see Steve Yegge say that he never successfully built anything with Gas Town (other than Gas Town).

In https://danluu.com/ai-coding/, I mentioned not finding any of these super vibed orchestration frameworks useful because the reliability was too low (in terms of them actually getting agents to complete a non-trivial task). Turns out the author of the best known of these frameworks had the exact same issue.

My article "How to Write an Effective Software Design Document" is on the front page of Hacker News today. I tried submitting this myself 4x a couple months ago, and it flopped every time, so I'm excited to see this hit #1.

I regret to inform everyone that my copy of QBittorrent escaped its sandbox last night and downloaded a whole bunch of content owned by major corporations, and then my copy of Jellyfin broke containment and added those unfortunately-downloaded media files to its various libraries. I'm conducting an internal investigation to figure out how this happened, which will involve consuming these media files until the answers become apparent. Thank you for your cooperation during this trying time.

New blog post: Debian Code Search: Fast TurboPFor with Go SIMD 🥳

This August, I accomplished what I wanted for many years: I deleted the last cgo dependency in Debian Code Search! This was made possible by Go’s recently introduced SIMD support, because now we can implement the TurboPFor integer compression format as efficiently — more efficiently, in fact, by using the newer AVX512 instruction set! — as the reference implementation.

Today, I’m letting you know that toot.community will close permanently on 28 October 2026.

This decision is final, and the server won’t be handed over to anyone else.

When I started running toot.community, I really enjoyed it. Over time, it became more stressful and less rewarding.

Every day, I deal with spam, bots, technical issues, abuse reports, and user conflicts. Much of the moderation ends up being about personal disagreements rather than actual rule-breaking.

More importantly, I don’t enjoy how people interact on social media anymore. Too often, conversations turn hostile or confrontational. A small amount of conflict and bad actors takes up a disproportionate amount of time and energy.

I find myself feeling more angry or discouraged after spending time as an admin, and that’s not what I want from social media or a volunteer project.

There’s also the financial side. I’m very grateful to everyone who donated, but donations haven’t covered costs for a long time. I’ve had to shoulder most of the expenses, time, and responsibility myself.

The server is now closed to new registrations and will remain online until 28 October 2026, so you’ll have three months to find another Mastodon or Fediverse server and move your account.

You can find Mastodon’s official migration guide here: https://docs.joinmastodon.org/user/moving/

Please note that Mastodon can move your followers, but it can’t transfer your old posts or uploaded media to your new account. If you want to keep a copy, download an archive.

If you’d like to stay in touch, you can follow my personal account here (@jorijn).
