One of the interesting parts about software engineering is that each domain you work in requires re-asessing every pattern and best practise that seemed set in stone in other domains.

Been inspecting some pmap outputs these days, and could not find any decent visualization tools. Here is a quick one (nods to @simonwillison.net toolbox).

I'm not sure I'd advise solving that entire list of things up front. Pragmatism would tell you to fix those that you actually need, and at most have a plan for how would you address the rest.
I say this because I've seen several points (e.g code structure, devops processes, modules boundaries..) ->

When the AI spits 200-400 lines of functiona code based on a prompt, forcing a whole commit, pr, test, [review], merge cycle is just too much friction holding people back.

I mention the DORA report in the piece I published today. The report has a page about AI impacting sw delivery negatively. The recommendations (screenshot) about smaller changelists and robust testing make sense, but I'm somewhat skeptical that they are viable ->

The page about negative impact on software delivery performance landed right while writing this! varoa.net/2025/04/07/a...

Less reminded than learnt from the first time. Can't count the number of discussions I've had about using git tags as source of truth for release procedures and building artefacts.

1) We have decades of mgmt structures evolved based on a playing field where large scale coordination and alignment were essential. They are now obsolete. Some will take years to unwind them and will get overrun ->

Pretty close to my own experience so far on small projects, prototypes and such.

The implications of code turning into a low(er) cost commodity are wildly unexplored. (From @geoffreylitt.com on the other site, via @simonwillison.net)

Very interesting read on energy demand / supply in the context of AI evolution. (Unfortunately I forgot who I got this from)

This piece on AI Agents from @chiphuyen.bsky.social is fantastic. Definitions are crisp and productive to reason about the topic and goes into much deeper practical details than most of the content I've found so far

This resonates with how I see AI impacting sw eng. On a side note, recently I also chose “Mission Control” for an internal tool to monitor development status, the analogy is powerful. buff.ly/3Pb0B0L via @thorstenball.com

Anyone ran into this while running the 1brc on Linux? Hypefine is installed but the --output option is nowhere to be found in the man page. (cc @gunnar.bsky.social )
