Gradle 9.7.0 promotes Isolated Projects from experimental to incubating. The feature configures projects in parallel, making IDE sync and task runs significantly faster.

2.3M lines of code under 5 seconds 🚀

Inspiring and challenging 👍
Should be a benchmark for the future Crystal @CrystalLanguage releases 🙌

Uzun süredir üzerinde çalıştığım bir projeyi bugün duyurmanın mutluluğunu yaşıyorum.

Bilge ve Yonga: 7-12 yaş çocuklar için 32 kitaplık bir bilgisayar mimarisi serisi. Tamamı ücretsiz, bugün yayında.

Yıllardır üniversitede bilgisayar mimarisi anlatıyorum. Öğrencilerin çoğu bir işlemcinin içinde ne olup bittiğini ilk kez ikinci ya da üçüncü sınıfta duyuyor. Oysa bu konuların özü, doğru anlatıldığında bir çocuğun rahatlıkla kavrayacağı şeyler: bir anahtar açılır ve kapanır, her şey sıfır ve birle yazılır, işlemci bir buyruğu alır, anlar ve yapar.

Seride meraklı bir çocuk olan Bilge ile küçük robot arkadaşı Yonga var. Bilge sorar, Yonga anlatır. Kumdan yonga nasıl çıkar, bilgisayar neden ısınır, önbellek ne işe yarar, bir program nasıl makine diline dönüşür. Her kitabın sonunda kısa bir "Bugün Ne Öğrendik?" özeti var.

426 sayfa, her sayfanın kendi çizimi var. Kapaklarla birlikte 458 özgün görsel. Tarayıcıda okunuyor, isteyen PDF ya da EPUB indiriyor.

Bir şeyi de açıkça söyleyeyim. Bu seriyi birkaç yayınevine anlattım, destek çıkan olmadı, çoğundan yanıt bile gelmedi. Açık erişimi ilke olarak zaten tercih ediyorum, kitaplar bu yüzden ücretsiz. Ama çocukların kitabı eline alıp sayfasını çevirme deneyimini yaşayamıyor olması benim için bir eksiklik.

Ülkemizde yayıncılığın mürekkep ve kağıt masrafını hesaplamanın ötesine geçmesi gerekiyor. Bir eserin değeri satacağı kopya sayısıyla ölçülmüyor.

Basmak isteyen bir yayınevi çıkarsa kapım açık. Tek koşulum, kitapların dijitalde ücretsiz kalması.

3D modelleme ile ilgilenenler varsa, Microsoft görselden 3D tasarım üreten açık kaynak 4B bir model yayınlamış. Ben henüz deneyemedim ama ilgi çekici duruyor 👇

[Fatih Arslan @fatih]

Nice! I wanted something like this for a long time. See my previous rant last year. I think as engineers, we're already developing skills ourselves which model to choose. We use a less costly/fast model for implementing chore details, but use a higher reasoning model (slow and expensive as well) for serious tasks. So we already spend quite a bit time on it. Why not automate that part? Cursor Router does the automation. https://t.co/WcsHBCCrvr

Know Kotlin? Learning Rust is easier than you think. 🦀

I wrote a complete guide Rust for Kotlin Developers:
every concept side-by-side (Kotlin ↔ Rust), a cheat sheet, a 7-day plan, and 17 runnable examples.

We had a team of agents rebuild SQLite from its 835-page manual.

It created a replica in Rust which passed 100% of a held-out test suite.

Interestingly, cost varied 15x depending on which model mix we used.

Yes, this is my physical iPhone streaming
Yes, you can now simulate locations on a physical device
Yes, universal links and deeplinks testing has never been easier!

Just connect your device via USB and enjoy RocketSim 🚀

"Just use Postgres" they said.

So we built an app that streams multi-gigabyte video files right from Postgres.

Does it work? Yes. Should you do it? Nope.

But we learned a lot along the way.

[Glauber Costa @glcst]

I am excited to announce that we are officially writing a new version of Postgres. In Rust - and creating the LLVM of databases in the process.

In the span of a year, we have rewritten SQLite. Keeping the compatibility, increasing its feature set. MVCC, Types, (Live) Materialized Views, among other things. In the process of doing that, we have realized: At the end of the day, what makes SQLite special is that it compiles SQL to a database-specific bytecode. So why can't we compile *Postgres* to the same bytecode?

Turns out we can. I ran an experiment called pgmicro as a way to prove this hypothesis, and it works very well. It is time to make this official, and put the weight of Turso behind it. We shall give the world a modern take on Postgres. Wire compatible, but built on a new architecture.

We have already heard of others wanting to extend this. MySQL? Redis? the sky is the limit. What can we do if we do for databases what LLVM did for compilers? To prove how powerful the SQLite bytecode is, we are actually running DOOM compiled to the unmodified SQLite instruction set. And because Turso runs natively in the browser, you can play the game in your browser. With the database executing it.

I brought the World Cup onto my desk with Codex!

I built an AR app that projects a soccer field with detailed stats of both teams with Codex and Supabase!

I love Codex because it can also generate high-quality images. I used it to create the field's grass texture.

@utkusen I tried was quite happy with the initial results

Just published our third blog post about ExoPlayer and performance.

It’s about Self-hosted UI components & API, Choreographer-based seekbar and how it affects a bad frame rate, and several other trade-offs we had to make.

Profiling my @expo app using GPT‑5.6 + Argent helped cut a page's render time by 33% in a single prompt.

Performance debugging is getting too easy.

Every project management tool was designed by project managers, for project managers.

This one was designed for ADHD, dyslexic, and autistic brains instead. And it turns out that also makes it better for literally everyone who just wants to get work done without configuring a tool for two weeks first.

It’s called Leantime.

Most PM tools throw you straight into a task board and expect you to already know what a “sprint” is. Leantime is built around a different idea: tasks should trace back to a goal, not float in a backlog with no reason attached.

→ Ships with strategic planning tools, Lean Canvas, SWOT analysis, built to connect the “why” to the actual task list, not just a bare Kanban board

→ The same tasks render as Kanban, table, or list, whichever your brain processes better on a given day

→ Gantt-style milestone timeline, a built-in project wiki, and time tracking, all native, not four separate tools stitched together

→ Interface is deliberately built to reduce cognitive overload and context-switching, an actual design principle here, not an accessibility checkbox added later

→ Self-host via Docker in under an hour, your team’s entire project history stays on a server you control

Jira was built assuming a certified project manager runs the workflow. Most teams are five people trying to ship something, not an enterprise PMO. Leantime is what a PM tool looks like when it’s built for the second group.

Open source. AGPL-3.0. 10,000+ GitHub stars.

I built an LLM from scratch. Here's everything I learned along the way.

[Khairallah AL-Awady @eng_khairallah1]

Google CEO, Sundar Pichai:

"If you don't learn to how to orchestrate agents now, you'll spend 2027 catching up to people who started today"

In 30 minutes he explains why the best engineers stopped writing code and started building agents.

Most people think building an agent requires an engineering degree.

It doesn't. It requires one guide and one afternoon.
