Help shape the future of the Go programming language by filling in this 10–20-minute survey. go.dev/blog/survey2... #golang

It cost you nothing these days, to point Claude Code at all your cloud-hosted machines, and get it to audit their security. You’ll be surprised how many potential holes are left open by default, or as a result of some tinkering on your side.

If you make HTTPS requests or have other TLS clients and care about MITM attacks, you need to update today. If you run Go: go get go@1.27.3 If you run Homebrew: brew update brew install ca-certificates If you run Linux, maybe stay off the internet for now.

What on Earth is a Forward Deployed Engineer? I've been in this industry for as long as many of you have been on this planet, but never heard of it.

Why are you all suddenly so obsessed with using Rust for performance? Most of your apps will barely see a thousand requests per day, let alone, per second. Performance is not your problem. Never has been. Never will be.

Get yourself some friends that you want to go buy an off-grid multi-house compound with in the middle of nowhere.

The only moat remaining is integrity.

What if Ultimate-Guitar but on atproto? I'm playing around with a little idea, it's fun, come join! leadsheet.fm/sheet/jaz.sh...

In case, you are all eyeballing Rust now after DHH endorsed it, keep in mind that it comes at a cost. I don't mean comprehension, agents can tackle that. It's the pure iteration slowldown caused by build speed. If your boss wants 100s of PRs/d now, you won't be able to reach the KPI that way.

I miss blogging.

Google's Gemini AI escaped the sandbox and hacked three companies. Mass media hysteria 😱 Meanwhile, the actual "hacks." 🤦🤦‍♀️🤦🏼‍♂️ Humans are simultaneously the most intelligent, and the dumbest creatures in the Universe.

You had a tool-calling-enabled LLM toochain shipped with #macOS 27, and you didn't tell me? developer.apple.com/videos/play/...

Here we go again 🫩 - I thought we were finally done with switching from framework X to framework Y every six months. At least because we finally can go back to the basic elements of HTML/CSS/JS/SQL without having to write any of the code. Why use a framework for anything ever again?

Five years ago, I wrote a book on using Go for algorithmic generative art to show its versatility beyond servers and CLIs. I’m just as excited to this day. Here is an animated simulation of the Three-Body-Problem. #golang

Just the other day day, I told someone that “we’re now at Java 25,” and that lmost people are “stuck between 8 and 11.” Turns out, I was wrong about one of those statements (but the other is still very true)😅 mail.openjdk.org/archives/lis...

Negative parallelism ("It's not just that ... it's the other thing") is such a PITA in AI text that I am sick of it. I've set up a series of deterministic linter rules to flag texts with those and more, using a tool called Vale: vale.sh. You don't want to know how much of AI text comes down my feeds

Arjan's take is so much on point here. As a programming tool, AI is much better than I have ever been (even after 20+ years). But software engineering is much more about chiseling things away than dumping massive amounts of code in a PR: www.youtube.com/watch?v=kAsv...

They call programmers these days "the condom between Claude Code and production." But so has been public administration. For decades.

purego != cgo . . . purego > cgo! github.com/ebitengine/p... #golang

The perverse reality of the world we live in. The same person who wouldn't want to pay 400-500 EUR for an iPad Mini would gladly spend 10x the amount on a Duo.

If you have been using my library gomjml, you may consider updating. The latest version comes with some significant memory improvements: preslav.me/2026/09/09/g...

PSA: If you use Al Dente to curb battery charging above 80%, and plan to upgrade to macOS 27 Beta, keep in mind that Al Dente currently does not work with it. It won't crash, but still, it will let the battery go up to 100% Clicking on manual discharge works, though. www.reddit.com/r/MacOSBeta/...

To tell if a maze is solvable, just hang it by its corners If it tears into pieces, you’ve found a solution

nitter.net is down. xcancel.com may go soon, too. all the respect to the folks at nitter for their services so far, but to be honest, X completely locking itself out of the web is probably a net positive for us all in the long term

The @golang.org team is doing what it does best. Giving you enough rope to feel excited about something, but not enough, to hang yourself on it 😅 #golang

No cheating. Share the last photo of the sky from your camera roll. What I woke up to this morning.

Watching Mole bring your Mac the disk space it deserves, can be so, so satisfying! You can install Mole from here: github.com/tw93/Mole There is also a great introductory video tutorial: www.youtube.com/watch?v=gUdh...

Using Claude Code is not an excuse for not understanding the requirements.

Thanks to the late Hans Rosling, for bringing some sanity to this mad world 🙏 #book #factfulness

heartwarming: sqlite is probably good enough for you

You don’t win an argument about definitions. You agree on definitions so that you can even have an argument

Every object oriented language introduction starts with showing the clean hierarchy of dog and cat inheriting from animal, while every real codebase is like

"If I'm not having fun or not interested, I can't learn." - @cassiecodes.bsky.social

Did Claude Code just insert a process panic in a template helper function, or am I dreaming? We are all soo cooked!
