Another perfectly functioning MacBook saved from going to the thrash bin. The 5th or 6th one I save. This time, it’s a 2010 15” MBP with 8GB of RAM and almost half a gig of SSD (what a luck). Add Linux Mint on top, and it’s ready to end up with someone in need of a laptop. #apple #linux

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.

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.

What I really miss from JetBrains' Goland, is how easy it was to move types around. You just drag the type across packages, and all the imports get fixed automatically. I haven't been able to replicate it with CLI tools, and with AI agents, big refactors are even more wasteful. Has anyone been […]

The sad reality of Bluesky and Mastodon is that the folks I follow, don’t stop talking about Bluesky and Mastodon, and rambling about how bad X/Threads are. I spent a week around X and Threads, and the chatter there seems to be about anything else but the respective platform.

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=kAsvDoM9WJw…

If you are outraged at #Anthropic for exposing your texts as written by AI, how about this: just write them yourselves. Or, what's even better, don't write anything at all. You don't have to feel the pressure to always say something, even when you have nothing to share.

I can't stop you from using AI to write your posts. I also can't make you read them afterwards. But, you can at least make them sound less grandiose, by telling the tool to avoid “negative parallelism.” This is the infamous “Not because X, but because Y” that LLMs tend to overuse on all the […]

I have a suspicion that part of the reason why #macOS 27 runs so snappy, even while still being in beta, is because it only supports M-series chips. I know, there are IFDEFs and conditional compilation - logic says it shouldn’t be the case, but who knows.

LLMs tend to make our thoughts sound more grandious than they are. This is all, thanks to decades of writing indoctrination, inspired by the West's desire to sell ideas at a premium. The models simply copied it over.

Decided to try macOS 27 Golden Gate Beta on an M1 Mac Mini, and I was impressed. CPU/GPU benchmarks came out slightly better even than those of macOS 15 (let's not comment macOS 26 at all). What has your impression been so far? preslav.me/2026/07/29/installing-ma…

With all due respect to Supabase. I am sure it's a great piece of software (it sits on top of Postgres, after all). Sadly, it has turned into a Mar-a-Lago for bros who want to teach you how to build software, without having written a single line of code in their lives.

Thinking of MCP as “service discovery” is about the same as thinking of blockchains as “storage.” Does the job within the tight circumstances, but pretty terrible for any general-purpose use. To dissuade management and CTOs from slapping the term MCP on any API imaginable (because they will).

Is it too late for Python to ditch the sync-await madness, and move to goroutine-like micro-threads? I’m just sick and tired of people and AIs slapping async on every function in the call chain, only to figure out that a simple blocking execution would have made so much more sense.
