ktzar··on Italian parliament votes for return to nuclear energy
I had an non urgent injury in Spain last week. Went to A&E and was seen by a doctor, x-rayed, and given advice and the results within 90 minutes. I paid zero euros for that on top of my taxes. Maybe it's an Italian problem... And for sure Spain has its own issues as well, but private is not always necessarily better.
ktzar··on CEO fired developers to make room for AI. Developers create open source AI CEO
The cringe part is when a real CEO says that in a speech.
ktzar··on Show HN: A techno machine in one HTML file, with verifiable renders
Is there something similar to this that includes melody composition that's not tied to a scale? My son has been composing music for a couple years in Chrome Music Labs and he's definitely outgrown it, but I can't find anything that lives online (and ideally can be downloaded in a single html, love the idea) and allows any-length melodies to be composed within the browser with drumkits, etc...

Something like Caustic, but in HTML :-)

ktzar··on Universal health coverage could save $1T and 114k lives a year: study
What about all the new unemployed lawyers and bureaucrats that feed on the broken American system?
ktzar··on The Claudyssey: A line-for-line translation of Homer's Odyssey by Claude Fable 5
Emily Wilson's translation is way better, more modern and adequate to present-day readers and, probably more context aware.
ktzar··on Learning a few things about running SQLite
Is it me or this is one of the worst and knowingly less informed articles that has hit HN in a while?
ktzar··on Kimi K3: Open Frontier Intelligence
Hallucinates on the first question I ask, as 90% of these models that try to take shortcuts.
ktzar··on Developers don't understand CORS (2019)
it's one of my favourite interviews questions and very few people get it right.
ktzar··on Banned book library in a wi-fi smart light bulb
For someone so mindful of efficient software and use of energy, it's showing that images on that post are 5MB PNGs...
ktzar··on Free SQL→ER diagram tool, runs in the browser, nothing uploaded
Such an old problem solved very elegantly. Congrats. Remember the days of MySQL Workbench and how clunky it was.
ktzar··on The $15,000 AI Bill. Your $20 Subscription is a DELUSION [video]
A good way to think about it is finding how much it'd cost to buy and run a GPU that runs a model at around 100tk/s ("thinking" agents are not viable otherwise).

The figure mentioned in the video is not far off

ktzar··on ESP32 Bit Pirate, a Hardware Hacking Tool with WebCLI That Speaks Every Protocol
compatible with Cardputer?
ktzar··on Pandoc Templates
Pandoc is such an amazing piece of software. I used it to format my novel and made it part of a GitHub action to produce all the formats I required. I wasn't aware of templates, but some look really sleek.

I keep thinking that modern text editors are just flawed and markdown, with all its downsides and limitations, is what 99% is the people need.

ktzar··on I'm going back to writing code by hand
I don't think we're in the early ages... LLMs technology has essentially stagnated since GPT3.5, we just have bigger models that can handle more context. We're trying to cope for the lack of progress of the actual technology by coming up with contraptions of multiple models stuck together, Mixture-of-Experts, Reviewer models, PM models...
ktzar··on Do you even need a database?
Writing your own storage is a great way to understand how databases work (if you do it efficiently, keeping indexes, correct data structures, etc.) and to come to the conclusion that if your intention wasn't just tinkering, you should've used a database from day 1.
ktzar··on I built Timeframe, our family e-paper dashboard
I LOVE this, but I am still love the Sunday night family bonding moment of planning the week in the pen and paper weekly planner that also costs us $10 a year.
ktzar··on Two kinds of AI users are emerging
because we have an alternative that we humans can fix. The problem with AI is that it creates without leaving a trace of understanding.
ktzar··on Generative AI and Wikipedia editing: What we learned in 2025
Didn't know about Grokipedia, I've just opened an article in it about Spain, scrolled to a random paragraph, and the information in it is plain wrong:

From https://grokipedia.com/page/Spain#terrain-and-landforms > Spain's peninsular terrain is dominated by the Meseta Central, a vast interior plateau covering about two-thirds of the country's land area, with elevations ranging from 610 to 760 meters and averaging around 660 meters

Segovia is at 1.000 meters, and so is most of the top half of the "Meseta". https://en-gb.topographic-map.com/map-763q/Spain/?center=41....

I still stand on not trusting any of what AI spits out, be it code or text. And it takes me usually longer to check that everything is ok than doing it myself, but my brain is enticed by the "effort shortcut" that AI promised.

ktzar··on Small Kafka: Tansu and SQLite on a free t3.micro
I didn't know about Tansu and probably would not use it for anything too serious (yet!). Bus as a firm believer of event sourcing and change of paradigm that Kafka brings this is certainly interesting for small projects.
ktzar··on Lessons from 14 years at Google
Just that all of those activities you mention feel like a useless life compared to spending time with your own children in a house big enough for everyone to have their space, but small enough to force you to feel you're living with each other, seeing them grow and thrive, and going around your closest nature patch.

Not much money is needed to have a fulfilling and worth-living life.

ktzar··on Trump says Venezuela’s Maduro captured after strikes
There's no more proof that any Venezuelan election's results has been tampered with than with any US election. The state of Venezuela's state is sad, and so is the fact that millions of people have felt forced to flee the country due to economic uncertainty. But this is probably a mix of culture, ingrained corruption and US blockage for decades.
ktzar··on A small collection of text-only websites
I really enjoy using text.npr.org from my Kindle / Kindle Scribe. I'm really thinking about setting up a self-hosted RSS aggregator site that's Kindle-friendly.
ktzar··on I program on the subway
I developed a big chunk of my Scumm games decompiler in London's central line. I was lucky (or unlucky) enough to go far enough each day to always hand an empty seat and enjoy 30 minutes of me time each way.

All on a Chromebook with crostini. Cheap, long battery life and decent keyboard.

ktzar··on Measuring AI Ability to Complete Long Tasks
It's the same hunch we all have when we think we're going to learn something by watching tutorials. We learn by struggling.
ktzar··on Everyone in Seattle hates AI
I think you hit the nail in the head there. There's absolutely nothing we can do with AI that we can't do without it. And the level of understanding of a large codebase that a solid group of engineers has is paramount to moving fast once the product is live.
ktzar··on Microsoft's lack of quality control is out of control
Consequences of having early access to ChatGPT and getting AI knowledge debt?
ktzar··on Getting AI to work in complex codebases
And most importantly, we're paying with our brain and skills degradation. Once all these services stop being subsidised there will be a massive amount of programmers who no longer can code.
ktzar··on Tokens are getting more expensive
Also, the way models are evolving (thinking process, llms waiting for interactions with external entities via MCP, mixture of experts, ...) are making "useful chatbot responses" way way way more expensive than they used to be when you were pretty much hitting an autocomplete. To a level where these are starting to be prohibitive to run locally at a decent tokens/s speed, and we're being tied to using their models.
ktzar··on 6 weeks of Claude Code
Tried it a few times, and I feel I'm paying to become a worse developer for a maybe 30% speed increase in total.
ktzar··on Rotring 600 Ballpoint Pen
I still think that fountain pens are the pinnacle of writing stationery. One lasts generations and there's no consumables that need recycling or disposing of, if you use a rechargeable cartridge and buy ink bottles.
