The peril of laziness lost bcantrill.dtrace.org/2026/04/12/t...

Ahahaah this is comedy! Also won't link to it, but OMG that post is pure mental gymnastic in "this is exactly what I was proposing! see, I was right" in the middle of the bandwagon jump :)

1) you're more attuned to how they work and can spot stupid stuff easier

2) rumors abound that all providers distill their older models when preparing to publish a new one, to (a) free up some HW resources for the newest, with the happy side effect of (b) new model seeming way smarter than old

Gradski IT 2025 wrapped!

Ovaj smo mjesec na gradskoj skupštinu imali izvješće o radu u 2025. pa sam kao i prošle godine pripremio sažetak napravljenog u gradskom IT-u u protekloj godini kao novi newsletter.

That's a nice one! A bit hard to read, perhaps :)

graffiti ad for dry cleaning place: "Can AI do Laundry & Dry Cleaning?" "No, but we can!"

I confess I have very little knowledge of the field. This will be a learning opportunity for me! Especially the expressive power of the mutation framework (there are a few for Python that I'll look into) vs what AI can come up with.

Improving AI-generated tests using mutation testing So, I vibe-coded me an simple web app the other day (Pingu, a simple web monitoring and alerting tool, just for internal use). To increa...

I wrote up my experience with using mutation testing for catching bad, smelly, LLM-written tests: blog.senko.net/improving-ai...

Turns out, it's really useful and easy to do.

Turns out mutation testing is effective for making sure LLM-written tests actually do something useful.

It does need a separate prompt to point out areas for improvement or character flaws, otherwise it's just too positive :)

This is a fun and useful tool!

1) drives home the fact that once you publish something, it's there, there's no going back, no matter what legions of GDPR legalists tell you

2) interesting to see how the writing is perceived from a neutral party, might highlight some aspects one is not aware of

Hacker's Delight - Wikipedia

This has been happening for a while.

I have a copy of Hacker's Delight, full of fascinating things I'll never need in my software development career: en.wikipedia.org/wiki/Hacker%...

Not to mention a few volumes of TAOCP, which I fully plan to read one day...

My fireside chat about agentic engineering at the Pragmatic Summit I was a speaker last month at the Pragmatic Summit in San Francisco, where I participated in a fireside chat session about agentic engineering hosted by Eric Lui from Statsig. …

Flame wars and hype fatigue I've recently seen many people suffering form hype fatigue. People just don't have the emotional energy to engage for the N-th time wit...

Nisam pitao detalje (bilo je prije ove vijesti pa nismo puno o toj temi), moguće da lokalci samo sumnjaju da je minirano ali nikad nije provjereno.

Ako sam dobro skužio vijest, to je za sve lokacije gdje se zna da jesu bile. Tko zna gdje se još ne zna.

Neki dan se zapričao sa jednim majstorom (uređivanje vrta, sječa stabala, itd), dogovara posao u nekom selu iza karlovca, treba srušiti par stabala koje prijete kućama.

Šuma minirana, ekipa za razminiravanje skupa, nitko ne želi platiti, a ovi ne žele na vlastiti rizik.

Bit će ovog još godinama :(

I've used the walkthrough pattern recently to walk me through a 7k line PR (in several commits, but still...) that I did with CC a few weeks ago.

I wanted to do a proper review and the walkthrough "eased me in" and oriented me from where to start looking.

I was curious about the sources, found it here: www.reddit.com/r/LocalLLaMA...

Tried to reproduce, works great for "what model are you" in Chinese. But "what is your name" reports differently - as "ChatGPT" 🤣

Code reviews don't scale when you have thousands of lines of code built daily. We need to rethink them in the age of AI.

I posted some of my thoughts about it here: senkorasic.com/articles/ret...

I love the "velocity without understanding is not sustainable" line from Mary-Anne's post. Pithy, accurate, and actionable: don't go faster than you can understand.

Ever wondered what that helpful "curl | bash" installer actually does?

Paste it into curl-bash-explain.dev and find out!

Zelena (tirkizna?) boja na "su ljudi" je malo off u odnosu na film, ali oprostit ćemo im.

Lansirali smo novi web gradskih vrtića s objedinjenim pregledom javnih nabava i natječaja za zapošljavanje. Uz to su modernizirane i ujednačene stranice pojedinih vrtića s lako dostupnim informacijama o upisima, jelovnicima itd.

Github is down. If only we had a DISTRIBUTED version control system...
