It's sad because I have many support scripts written for the Deno runtime. The good thing is Node.js was pushed to implement many ideas from Deno meanwhile, so the migration should be relatively simple, as I managed to move most of my dependencies to JSR versions.

Abstract
We study the impacts of AI coding assistants and agents on software engineering work, using
a novel proprietary dataset from an engineering analytics platform, covering 300 million work
events — including GitHub coding activity, Jira issues, and Google Calendar events — across
718 firms. We use a staggered difference-in-differences design, exploiting variation in firm-
level adoption timing of AI coding assistants and agents. Both technologies increase coding
productivity. However, productivity gains do not fully pass through to changes in software output
or employment. For AI agents, this incomplete pass-through reflects a bottleneck from code
review: review times increase, a larger share of code updates require revisions, and reviews
involve more comments. We develop a model of software production to structure these results, in
which AI affects both productivity and quality of intermediate outputs, and in turn can generate
a review bottleneck and limit pass-through.

I love it when nature documentaries also provide extremely timely commentary about our current world and state of affairs at large: "In more extreme environments competition is less decisive because it has one great drawback: It uses up a lot of energy. In the mountains, energy is a commodity […]

@honzajavorek užívej si podzimní El Niño a neptej se, jak to, že tu je. :)

I started programming computers in 1973 and one of the very first fundamental truths I learned about software development is this: The gulf between a program that works and a program that works for other people is orders of magnitude larger than the gulf between a program that works and no […]

You are using macOS on Intel x86_64. We do not provide support for this platform (as-of September 2026, announced August 2025). Apple have dropped Intel x86_64 support in macOS Golden Gate (27). GitHub Actions are dropping macOS Intel x86_64 runners in 2027. Homebrew is a non-profit project run […]

@honzajavorek že nesmíš mít psa na vodítku?

@ales.roubicek.nameOct 3, 2026, 7:35 PM

@honzajavorek @tomaslatal.cz ;)

@ales.roubicek.nameOct 3, 2026, 7:26 PM

@honzajavorek @tomaslatal.cz web search je jen tool. Pokud LM Studio umí tooly, mělo by to jít. Pokud ne, MLX.studio to umí.

@honzajavorek když budeš mít chuť můžu ti někdy ukázat, jak efektivně běžet lokální modely na macOS, když máš těch 32GB RAM :)

@ales.roubicek.nameOct 3, 2026, 11:41 AM

@honzajavorek BTW je to převlečená Gemini

@ales.roubicek.nameOct 3, 2026, 11:40 AM

@honzajavorek škoda toho Airu. S 32GB RAM asi bude throttling častou zábavou.

@honzajavorek @programydovoleb BTW Cloudflare Workers mi u některých věcí, který by se museli v Apify bruteforceovat, prostě fungujou. Většinu scraperů, co mám, mám ve Workerech. (a pro milovníky škrcení už tu jsou i Python Workers https://blog.cloudflare.com/python-workers-ga/)

@ales.roubicek.nameSep 29, 2026, 8:33 AM

@honzajavorek @programydovoleb víš jak, Apify, a ještě navíc s residential proxy, je těžkej kalibr na něco, co vypadá spíše jako rozbitý server než cílený blokování :)

@ales.roubicek.nameSep 29, 2026, 7:48 AM

@honzajavorek @programydovoleb ale je tam opakovaný problém s SSL handshake
