"And is this hallucination in the room with us now?!", and 50 other questions I'd have for AI if AGI would actually become a thing. :P

GitHub Copilot Business, Claude Teams, ChatGPT business, ... All these AI management portals are a big hot mess. Overwhelming, underwhelming, scattered, unclear, wrong at times, barely usable most of the time. Almost as if they were vibe coded too hastily ':D
Organizing INFI-CON at @infi.nl today and the vibes at the office are off the chart :D Modded roomba's driving around, bicycles and mannequins, Winamp-style visualizers being tested.... 🤯😁 - and we haven't even started yet!
Absolutely insane that Claude makes me choose between (a) login with Google (I certainly don't want Google to be able to rug-pull access to all sorts of platforms), or (b) an email based login flow (with emails that arrive less than 10% of the time).
Je twijfelt wellicht nog? Niet doen! Over twee weken op DO 11 JUN vanaf 13:00 is INFI-CON, en het wordt briljant! Keynote van Dylan Beattie, plus nog 4 presentaties over "briljante technologie"! Aanmelden kan op: con.infi.nl - tot dan!?
This is going to be an awesome event - Utrecht's such a great city, the tech scene in the Netherlands is excellent, and I'll be telling y'all the story of how a joke language based on Bon Jovi songs became a tour de force of modern software engineering.
Infi@infi.nl · 3mo agoOur INFI-CON 2026 (June 11th) keynote is by none other than @dylanbeatt.ie, titled "How To Be a Rockstar Developer"! (Keynote will be in English, other presentations are a mix of Dutch and English.) - About Technology, but there might be actual rock involved!

DO 11 JUNI 2026 (vanaf 13:00) eindelijk weer: een INFI-CON! Gratis toegang, een (Engelstalige) keynote van Dylan Beattie, plus vier andere sprekers (Nederlands en/of Engels) over tech die briljant en absurd tegelijk is! :D #Infi #Utrecht Info en aanmelden op: con.infi.nl
Farewell ConEmu! <3 You've been a great help for the past 10ish years, but the built in Terminal on the Windows machines I still have (for now :D) seems good enough to be back at 'stock' tooling.
I like this new "minimum release age" feature in all package managers. But... once everyone will be using it, who will then feel out the supply chain attacks? 🤔😅 Or are there enough security scanners around to find things in an automated fashion?
Shocking how few truly FOSS apps I have on my Android phone. Less than 1/8th or so, if even that. 😔

Had a ton of fun today rapid prototyping useful but throwaway code in a mini-game codebase! I knew far too little Rust to hand-craft things, and GenAI enabled prototyping pretty complex features very quickly. :D
Tried the Stack Overflow AI features in the "new" mode, but I feel like it needs quite a bit of work still...
In almost all queries to LLM's I will start with: "Anno <month+year>, ..... <actual query here>." Plus, my custom instructions tell it to lead in answers with its knowledge cutoff point. That way it'll realize in time that searching for up to date info is needed for a proper answer.
The "SKILLS" stuff may have been "standardized" but not all tools follow it equally. I'm sure it'll even out soon enough, but for now having different tools on different machines can be a hassle!
Using Teams at a client, when usually using Slack, is... a learning experience ':D For every 9 features where Slack's superior, there's 1 where Teams takes the win. (And they are nearly never on par with each other.)
Ralph loops and similar flows where GenAI agents leave instructions for their future "selves" makes me wanna rewatch Memento! :P

The best "solution" to stop Gemini from inlining YouTube tutorials at the end of answers is seemingly a custom instruction to always replace the video URL with the rickroll URL. 🫠
The #AdventOfCode 2025 (unofficial) Survey Results are live! 😁🎄⭐⭐ Results at: jeroenheijmans.github.io/advent-of-co... Feel free to give this Reddit post some love too: www.reddit.com/r/adventofco...
AoC (Unofficial) Survey Results
Results dashboard with the yearly (unofficial) Advent of Code participant survey

Tiny teaser for the #AdventOfCode survey results that are coming up this weekend! I'm *amazed* at how stable the main results for "Reasons to participate" are. For 8 years in a row every answer gets picked roughly by the same % of people! 😲 Somehow I'd expected at least *some* fluctuations!
Already had a strong dislike for Claude's email-sign-in-only setup (just gimme username + password + totp, will ya!?), and now that I want to try something we can see why.... "We have trouble delivering mail to some providers, check your spam or try again later!" Right.
Using [company]@[mydomain.nl] for accounts is a fantastic first line of defense against phishing and its likes. E.g. receiving a "Bank Trouble" email on my "LinkedIn" email address immediately puts me on guard. I can almost always disregard "From" when receiving mail, and look at the "To" field.
Final call for my #AdventOfCode survey of 2025! If you haven't already, fill it out at forms.gle/TAgtXYskwDXD... plz! I hope to close it and start working on results late on the 12th, and to have the results shortly thereafter. Stay tuned :D
