In Japan 5yo kids take the subway alone...
joak··on The climate benefits of retiring an operational combustion engine vehicle
There is an element I haven't seen in this conversation: as the number of combustion engine cars goes down the number of gas stations also goes down. At some point, combustion engine drivers will start feeling range anxiety. So when you get rid of your fossil-fuel-burner vehicle, you are pushing others to do so.

The full calculus of CO2 emissions reduction should also include the reduction induced in others.

joak··on What is a quantum computer good for? nothing – yet
Google had a paper last year explaining that: https://blog.google/innovation-and-ai/technology/research/us...

We do not have any useful algorithm to run on a quantum computer.

The problem is not that we do not have yet quantum computers powerful enough, but that even if we had such computers we would not have anything useful to run on them.

joak··on Childhood Computing
You could use this audio at 300 baud by recording it on a standard audio cassette. Then play the audio back as input to the modem to retrieve the data
joak··on Childhood Computing
Actually in 1982 I was able to store my programs on standard audio cassettes. Hardware needed: a modem and a cheap tape recorder. My apple II modem would chirp the ascii binary like Starwars' R2D2, I'd record that and when needed I'd play it back to the modem.
joak··on High-temperature memristors enabled by interfacial engineering
«Here, we reported graphene (Gra)/HfOx/tungsten (W) memristors that operated reliably up to 700 °C»
joak··on Artemis II is not safe to fly
I agree, this report from astronaut Camarda should really alarm NASA.
joak··on Artemis II is not safe to fly
This report from astronaut Camarda is indeed a bomb. Scaring.
joak··on French e, è, é, ê, ë – what's the difference?
The famous ghoti as an alternate spelling for fish. Gh like in enough O like in women Ti like in nation
joak··on Roomba maker goes bankrupt, Chinese owner emerges
The DJI ROMO robot vacuum is amazing. It shows what can be done with today's technology.

My Roomba is just crap compared with DJI's. I'm not surprised they went bankrupt.

joak··on Forget AGI–Sam Altman celebrates ChatGPT following em dash formatting
Excerpt: “The fact that it’s been 3 years since ChatGPT first launched, and you’ve only just now managed to make it obey this simple requirement, says a lot about how little control you have over it, and your understanding of its inner workings,” wrote one X user in a reply. “Not a good sign for the future.”
joak··on Why do voice transcription apps charge monthly when Whisper runs locally?
This is an ad for speech-to-text app that you need to pay for

Spokenly is free (one time fee of $0) and does the same (and even more)

joak··on How to maintain good vision amidst the myopia epidemic
Interesting, it seems really likely that more light indoors should be good. Do you have a reference, a scientific study on the topic? Thanks!
joak··on Microsoft AI chief says only biological beings can be conscious
Mustafa Suleyman is also DeepMind co-founder
joak··on Keep Android Open
If you leave under a dictatorship you definitely don't want to reveal your identity to develop and distribute an app that fights the government.
joak··on uBlock Origin Lite in Apple App Store
The normal uBlock origin extension can be installed on Orion browser for iOS

Orion is webkit and can be set as default browser.

joak··on The QMA Singularity
Excerpt: But here’s a reason why other people might care. This is the first paper I’ve ever put out for which a key technical step in the proof of the main result came from AI—specifically, from GPT5-Thinking.
joak··on LLMs are still surprisingly bad at some simple tasks
More generally LLMs are bad at exhaustivity: asking "give me all stuff matching a given property" almost always fails and provide at best a subset.

If possible in the context, the way to go is to ask for a piece of code processing the data to provide exhaustivity. This method have at least some chance to succeed.

joak··on Ask HN: What Arc/Dia features should we prioritize?
I tried to migrate to Zen but I missed Arc's profiles. Container tabs do not replace profiles. I like to switch personae/profiles by switching spaces.
joak··on Ask HN: What Arc/Dia features should we prioritize?
Each profile with its own cookies, passwords, credit cards, etc...

Each profile is a different personae

joak··on Ask HN: What Arc/Dia features should we prioritize?
Arc style profiles, one profile per space.

Super practical for pseudonymity, and for separating work from personal life. Or avoid mixing data and confusion when working different jobs.

joak··on Why Browser Company at $610M is cheap
Zen browser is a Mozilla based clone of Arc browser...

It's a good/possible alternative

joak··on A power shortage could short-circuit Nvidia's rise
Nuclear power plants take something like a decade to build (after permitting)

It makes more sense to go for PV plus batteries that can be installed in a matter of weeks

joak··on The unbearable slowness of AI coding
The issue I have is that it produce code that is unmaintainable. Poor modularity, code duplication, hidden errors producing spurious bugs, ...

Nonetheless it's ability to produce code that works is impressive, it's useful for learning, to generate throwaway code...

For example I can ask for a piece of code generating stats from logs. The code is not meant to last and will have few users (the devs), so maintainability is not an issue.

joak··on China develops first pregnancy robot, sparking ethical debate
One day, in a near future, most probably in this century, it will work.

I'm impressed, way ahead of roomba

joak··on Unitree A2 Stellar Explorer robot can carry a grown human
China is leading in robotics.

Remember Boston Dynamics' big dog...

This robot is the same idea. So it's not new, 10x better though.

joak··on What'll happen if we spend nearly $3T on data centres no one needs?
I was surprised that in the energy solutions to power the data centers the FT journalist just proposes nuclear and gas but not the obvious photovoltaics + storage.
joak··on Orion Browser
Safari is unusable on iOS: no ad blocking.

Orion bring uBlock origin, this is game changing

joak··on Orion Browser
Orion is my way to have ublock origin on iphone/ipad.

Is there another way?
