- Reposted by Bernard KolobaraI'm still writing code the hard way. I'm slow. I like to think critically about every line of code and fiddle with variable names until everything looks right. I treat code as a liability and try to ship only what's necessary. It's hard to imagine writing code any other way.

- Reposted by Bernard KolobaraThis is good read about the state of open source and AI. Unfortunately, I'm skeptic about GitHub doing something to make things better. So far, their latest changes in PRs, splitting large PRs in one page per file(WTF), make reviewing code generated by AI worse, no better 🤷♂️
- I don't have any research to back this up, but I suspect that excessive usage of coding agents can be very unhealthy for your mental health.
- Weekend thoughts on Gas Town, Beads, slop AI browsers, and AI-generated PRs flooding overwhelmed maintainers. I don't think we're ready for our new powers we're wielding. lucumr.pocoo.org/2026/1/18/ag...
- People like to call them bicycles for the brain, but I think it's more like smoking for the brain. The productivity gains might "look cool", but long term the damage is just not worth it.
- Reposted by Bernard Kolobarai hate how far we've slid into "scamming is legal now" just constant bullshit everywhere and it's wrapped up in gambling too and it's not even like i'm at risk of falling for it, just creates a bad feel to the world
- Reposted by Bernard KolobaraI love the way GitHub constantly goes down now

- Some people are very much pro llms writing code, but against llms in written communication [1]. The truth is that it produces very low quality results in both cases, but it's easier to get away with it in code. [1]: rfd.shared.oxide.computer/rfd/0576
- I was feeling the same, but couldn't put it in words. Now I can. Agents are the Frontpage of 2026

- Reposted by Bernard Kolobaralmao claude code just deleted my entire project in yolo mode and i had no backup
- Too bad that quality is the only metric that actually matters today, and nobody bothered to optimize for it. Instead everyone is hyper focused on getting the last 0.1% out of shipping speed.

- Reposted by Bernard KolobaraFor my team, being about the details, creating, sharing, learning skills that can be applied, and trying your best, will help us survive this radical shift in how we design and code in 2026. Don’t underestimate yourselves, strive for the best ⚔️
- Reposted by Bernard KolobaraI have been using the cloud services at work (because I'm expected to) and, while I remain skeptical that they lead to any meaningful performance gains, I cannot deny that they are *fun* and reduce subjective feelings of friction.
- Being on "the list" seems like great publicity. Too bad I hand write all my code.

- In the good old days we would already have a Claude_Opus_4.5_Pro_1.4Tb_Repack_Portable.exe on the torrents.
- We reached the SaaS endgame. Everything is a subscription and the consumer is priced out of running this stuff at home.
- Reposted by Bernard Kolobarawhenever you see some crap like "opus is 100x leverage the best founders can now blah blah blah" check the link in their profile they haven't even figured out how to use opus to update the "product" they're "working on" to not be crypto bullshit
- I don't understand how people "vibe-code". To get something useful out of an agent you need to set very strict rules, write an in-depth specification and have some kind of test loop, so that the agent can iterate on the solution. If you leave any room for interpretation, the output is just garbage.

- AI coding agents are the ultimate "second screen", do something else while you just occasionally check on the work.

- Reposted by Bernard KolobaraUnpopular opinion: Code review has never been more important than in the age of AI-generated code. To maintain a codebase I really need to know: - What this code does? For the code to satisfy this criteria it needs to be carefully reviewed (by a human) before the merge.

- Reposted by Bernard KolobaraYou can apply this to so much! I refer to this as “labs thinking.” It’s where you allow yourself the degrees of freedom needed to explore the problem space. Then once you’ve formed a better world model you can build a more accurate representation within tighter constraints.

- .expect() is so unintuitive to me. You are supposed to phrase it in a way where you explain why it is not failing, for example .expect("the var exists"). But 80% of the time I write why the call is failing. I like to explain why the call failed, not why I was assuming it's going to work.
- #rustlang hot take: We should rename .unwrap() to .or_panic(). (And .expect() to .or_panic_with().) "Unwrap" is a terrible name for the panicking function, especially since we also have things like .unwrap_or() and .unwrap_or_default() which never panic.

- Reposted by Bernard KolobaraGood thing then that I'm giving a talk in 4 days at Rust Forge on (among other things) making inference breakage no longer actually break things 😁

- Reposted by Bernard Kolobara#GitHub doesn't have good competition for individuals / small teams. Can't commit to Codeberg due to stance on private repos & commercial projects. GitLab seems as bloated and more expensive. Forgejo seems easy to self-host, but I'd rather not at this point. One of these days.
