What a day: finished my 1st Aqua Bike competition. 53th out-of-water (the last one!), and finished after the bike split at the 26th place - in 3:48h! 💪

What a day! mMy longest bike ride of my life! 😎 #mallorca

This is one of the most balanced critiques of AI I've read so far. "Reviewing AI output all day without the dopamine of creation is not a sustainable job description." tomwojcik.com/posts/2026-0...

Max Schrems ist ein Jurist, der mit seinem Einsatz für Datenschutz- und Grundrechte international höchst erfolgreich war. Peter Steinberger reitet eine Bubble, die uns derzeit alle mit einem ganzen Bündel gefährlicher Probleme konfrontiert. Österreichische Medienpolitik so:

We released DuckDB v1.5! This release comes with a “friendly CLI” client, a new (opt-in) PEG parser, support for VARIANT types and many lakehouse features. It also ships a new network stack, a reworked geospatial extension, Azure writes and an ODBC scanner. Read more at duckdb.org/2026/03/09/a...

It's so "funny" when #ChatGPT hallucinates about SQL Server 2025 feature internals, which are not documented anywhere. And then it says "sorry", because it delivered garbage to you... #StrangeNewWorld

CoPilot in SSMS reads from my database/sql server instance, but doesn't show me any executed queries. This is *so* dangerous for your production data - CoPilot could just pass some of your sensitive data to the LLM provider... #ai #llm #datasecurity #gdpr

The new Ballmer Curve: tomwojcik.com/posts/2026-0...

When my MacBook Air M3 24 GB outperforms my AMD Ryzen system (128 GB RAM) with a RTX 3080Ti GPU for local LLM inference. The Unified Memory architecture rocks! 💪

Anthropic has style and responsibility! 👍

Most programmers are taught that L1 is the “top level” cache on x86.
 It’s not quite true anymore! 
Intel calls it the Decoded Stream Buffer (DSB), AMD the OpCache. Only enough room for ~4,000 micro-ops, but there are interesting ways to take advantage of it.

I have never thought that software engineers will be substituted by endless loops... #AgenticAI

"new consulting pipeline almost shut off starting in December" -> same here! 😪

WTF! 🫣

Never, ever trust an LLM *blindly*: Claude Code generated me frontend code that stores a bearer token (used for authentication against the REST API backend) in local storage. That's the perfect use case for XSS attacks... #fail #llm

Nobody needs you anymore…

Using various LLMs to design and implement a web app. The results are amazing.

I’m not really surprised, but still…

Yesterday I built a full end-to-end PoC stack with OpenAI Codex 🚀, from frontend to backend to database, and then added load testing and observability across the entire flow 📈 Current architecture: Vite web frontend 🖥️ -> Rust backend service 🦀 -> PostgreSQL 🐘

Working in VScode with the @continue.dev extension against the model "meta-llama-3.1-8b-instruct" that runs locally in LM Studio on my MacBook Air (M3, with 24 GB unified memory).

Over the past two months, I’ve been diving deep into agentic coding with tools like Claude Code and OpenAI Codex. It’s incredible to witness how rapidly software development is evolving - and just how much leverage you can gain when you use these tools intentionally.

I want to have that confidence of an AI agent...

Discovered an awesome article (and the entire site) via HN. Example: "How is data stored?" www.makingsoftware.com/chapters/how...

I'm "quick-reading" through the #Oracle Database documentation. I'm impressed, *really* impressed. There are so many features which are not part of #SQLServer.

Während ich mich im Orkan durch Graz gekämpft habe, hat Philip seinen höchsten Gewinn seines Lebens eingefahren: ein Sieg (4:30h Spielzeit) gegen einen ELO 2150 Gegner! 💪 Nach 90min Pause geht es um 16:00 gegen einen Fide-Meister aus Ungarn weiter… 🤗 #chess

But it‘s still amazing to see, how *much* you can actually achieve with the 20$ plan - in comparison to Claude Code…

Function name of the month: "reap_zombies" 💪

Neo has a meeting at the #Oracle. Let's see if he takes the red or blue pill..

After a 12-hour long coding session with OpenAI Codex, I have now finally a working Ring-3 to Ring-0 transition through syscalls (implemented via int 0x80). It involved *a lot* of refactorings and guiding by a human person ;-)

I have now officially more #Rust code than C code in my #osdev repository! 💪

The #Linux Kernel has now official support for #Rust: git.kernel.org/pub/scm/linu...

I have now a fully working preemptive scheduler in my OS available. Spawned tasks can already put into sleep when they wait on external resources (currently key presses from the keyboard). Everything is written entirely in #Rust - besides the necessary bootsector stuff.

OS development with GenAI: I'm still smarter 😅

OpenAI Codex told me that it could also generate code that violates active patents... This is then your problem, because it (Codex) is just a code generator - nothing more...

Naja, der Vergleich passt nicht ganz. Aber nachdem AI die Berufslandschaft in den nächsten Jahren massivst verändern wird (bzw. es aktuell schon macht), ist es durchaus gut, wenn sich Kinder/Jugendliche bereits jetzt in der Schule damit kritisch beschäftigen und Know-How in diesem Bereich aufbauen.

GPT-5.3-Codex and Claude Opus 4.6 are released!

💪

It seems that the Microsoft CoPilot licensing is more complex than the Oracle licensing... 😱 For me, OpenAI Codex is still the winner. Claude Code is "ok", but the Plan Usage Limits are sometimes just gone within *minutes*, where I can "talk" to Codex for hours - about the same code base...

I'm still actively working on this series on The Phoenix Architecture, but I've taken a pause in posting while I think about a new angle related to source control. In the meantime, if you haven't already been following I'd love to hear more thoughts aicoding.leaflet.pub
