fcatalan··on Lab on a Contact Lens Can Measure Stress Through Serotonin
This will come handy for my Voight-Kampff testing machine startup.
fcatalan··on VSCode's SSH Agent Is Bananas (2025)
I just removed 5.5Gb of stale ~/.vscode-server from a dev VM
fcatalan··on Spain orders blocks on Archive.today and its mirrors
By my count 30 years out of 48 are not nearly 100%. If you consider Suarez, Calvo-Sotelo, Aznar and Rajoy leftists you might be a bit too much out there.

Since the end of the Civil War in 1939, Spain has spent roughly 65% of the time under Right/Far-Right rule and 35% under Left/Center-Left rule.

My grandparents would routinely call the 40s "The years of hunger" so you can guess which way it went.
fcatalan··on I were 17, I'd learn how to build LLMs from scratch
Me too:

ages 8-15: lots of great 8-bit computer fun.

ages 15-20: girls, booze, motorcycles.

20 onwards: get a PC, back to computers, realize how much I've been missing.

To be honest, judging by my own kids and their friends, late teens seem to generally be an era of hard to avoid stupidity.

fcatalan··on How does IKEA come up with names for its products?
That's how they getcha, and then go full midsommar...
fcatalan··on 2026 Eclipse Webcams
I now read that German police will stop and check families with kids in airports the days immediately before and after public holidays. Chilling "Ihre papiere bitte" vibes there. Not doing a great job at avoiding stereotypes, you guys maybe could historically benefit from saner laws and a healthier relationship with them.

All that tough talk stems from fear.

That fear is fed with dog whistles like "fighting age men" and ample misinformation.

Ceuta is guarded by a 10 meter tall fence equipped with thermal cameras and noise detectors. This people didn't jump that fence, just swam around its end into the sea.

Ceuta is garrisoned by elite units of the Spanish Army, on top of border patrol and police. We have plenty of guns there, but choose not to use them on misled teenagers in swimming trunks and flipflops.

No lasting damage has been reported in Ceuta. This has been less violent than sport event celebrations.

Consider stepping out of the information bubble that weaponizes you as a supporter of mass killing.

In 2014 there was an attempt to swim over in the same exact place by just 300 people. Spanish police used rubber bullets to repel them and 14 died in the water.

More than 60 have died this time, even unoppossed.

Deaths could have been easily in the hundreds or thousands in the case of a similar heavy handed response, but our corrupt and incompetent forces have succesfully controlled and defused the situation in a peaceful and humane way within 24h.

I'm quite proud actually.

Stop sealioning, this is simply Morocco once again using its desperate young population as pawns in their underhanded "diplomacy".

Those people had no way to stay in Ceuta or travel onwards in any way, so this was just a deadly flashmob performance.

Of course the whole thing does double duty in arousing fascists and racists in Spain and the EU, for which the cui prodest list is quite ample.

fcatalan··on A migrant surge tests Spain's open policies
We are not in the business of mass massacres. Maybe the US should come and study how to deport 60k people in 24h whithout having to shoot anyone.

In Spain, if you drive 1 h 20 minutes southwest of Madrid you get to Talavera de la Reina, which is a town all about ceramic and pottery:

fcatalan··on NSF pilots 4-year PhDs with industry research placements
Practicality and utility to the student must be the reason I started getting junior software engineers that are computer illiterates out of whatever Java IDE they were taught in.
fcatalan··on Handbook.md shows that long policy documents do not reliably govern agents
Off topic, but I'm kinda sad there's only one Cosma Shalizi in the world. That dude is a treasure, I've been a fan for decades now.
fcatalan··on A.I. companies are recruiting electricians and carpenters by the thousands
"Aluminium carpentry" is a thing around here: people that build and install window frames, metal gazebos, conference stalls, custom sheds and so on. These huge data centers probably aren't using the quaint standard data center server cabinets.
fcatalan··on What is happening to jobs? Separating AI hype from reality
For me it feels a lot like generated images or video. I've made lots of things now, but those that are 100% LLM written "work" but are uncanny, weird and the details are wrong everywhere you care to look in detail.
fcatalan··on The largest available Minecraft world, totalling 15 TB
I spent a few weeks there back in the day. After the ordeal of surviving the spawn I remember it as a haunting and melancholic experience: you kept finding decayed places, huge projects long abandoned, vandalized monuments, vague traces of simpler dwellings, hidden orchards.

I haven't played a lot of Minecraft but I'm glad that most of the little I played was there.

fcatalan··on Spain Orders Blacklist of Palantir from Public and Private Companies
The made up cases are so many that they deflect each other and the few real ones. The real scandal is the state of our judicial power.
fcatalan··on Caffeinated and decaffeinated coffee lower stress, depression and impulsivity
My therapist asked me to track my binge eating episodes, empty log after a week...
fcatalan··on The last Romans are still around
My grandfather was a smith in deep rural Spain. He made and fixed many roman ploughs, well into the 70s. They were called that because they were pretty much the same tool the Romans used.
fcatalan··on Becoming a dad changes men's brains
This is not mere learning, must have some kind of pre-wired special mechanism because it's very quick and very strong.
fcatalan··on Becoming a dad changes men's brains
Are your kids teenagers already? Telling them in front of their friends is 10x better.
fcatalan··on Becoming a dad changes men's brains
Exaggerating a bit, I felt like my old self was dead and I just happened to somehow have inherited his memories.

But a more concrete thing: While before I might have been saddened about bad things happening to kids, like any normal person would, after having kids myself I experience an stronger reaction:

I get almost physically ill when I hear about kids getting harmed.

fcatalan··on Proportional-Integral-Derivative (PID) controllers
I signed up for one of the first MOOCs ever, about self driving cars by Sebastian Thrun, and of course PID was part of the curriculum.

I think that PID hits a certain sweet spot between cleverness, ease of implementation and practical utility that makes it catnip for the typical programmer's mind.

I liked it so much that when we had to implement it, I downloaded an open source driving simulator to see it work there instead of the simpler python environment we were using.

fcatalan··on How many of the 170k English words do you know?
71050, not bad for a non native speaker I guess. I missed 9/100.

But to be honest many that might catch out a native speaker are just the Spanish/French/Latin word, so it was too easy in a way.

fcatalan··on Making peace with your unlived dreams (2023)
Thank you for this recommendation. This last week I have read this, and then also Meditations for Mortals, and they felt illuminating and like written specifically for me.

And without really changing anything about what I am actually doing, I now feel much better about it, because these are the right things to be doing now and anguishing about the ones that I can't get to is just sabotaging myself for no gain. It looks so simple now...

I still have a lot to digest, but having read thousands of books in my life, including dozens of self-help and productivity manuals, these have felt instantly life-changing.

Again thank you.

fcatalan··on Making peace with your unlived dreams (2023)
I don't dream or care about things I definitely can't do.

But there are still so many I can actually do that the opportunity cost of choosing any single one of them is infinite, and that leads to paralysis at worst and diluting your self while half-assing dozens of things at best.

Maybe one of them pays the bills, and even a nice house and a decent car. But it's just that, it is not what you really wanted to do, so you keep searching.

The "gift" of being a fast learner becomes a curse. In a few weeks you are an advanced beginner at almost anything. People marvel at how well you are doing, but you know you have just started and can now see how far you are from being any good. But to become good, you'd have to leave behind all the other things, and you can't pick. So you just start a new one for the quick dopamine hits and easy praise...

And then you are 50 and still don't know what you will do when you grow up.

fcatalan··on Ask HN: Why is the HN crowd so anti-AI?
Managers can barely direct me without shitting their pants. What saves them most of the time is my ability to say "No". Until LLMs can do that, which seems quite hard to do so far, good luck replacing me.
fcatalan··on Ask HN: Why is the HN crowd so anti-AI?
Skipping airplane maintenance is business-optimal for an airline. For a few months.
