logtempo··on Electric light transmits data faster than Wi-Fi
Introduced 12 years ago, is there is a technology limit or an interest limit?
logtempo··on The art of high performance computing
Few days ago I saw an article passing by,about chips hiting the kw floor.
logtempo··on Kids with chattier parents are more talkative, may have bigger vocabulary
It's an interesting question. Maybe a parent that monopolize the conversation impact negatively.

As for your experience, keep in mind that with statistics comes distribution of outcomes, you could be on that small % where things didn't work as observed in the article.

logtempo··on Kids with chattier parents are more talkative, may have bigger vocabulary
I think comments here don't focus on the most important point of this study, and article:

- citation: But the findings don’t necessarily mean kids speak more because they hear more speech, he says: Instead, “Adults [might] talk back more to kids who produce more language.”

- article show no evidence of socio-economic difference contrary to what was claimed before

- article have a huge database over the world, which makes it a strong study.

- article is a baby step: the next step are to know if it's talking to the child or if it's talking beside the child, for example.

logtempo··on Whatever happened to the zero waste movement?
Yes, not all cucumber are in plastic for various reasons. If plastic could be avoided, producers would avoid it as it don't bring any advantage from a marketing pov (aka it's not sexy like a cereal box is).
logtempo··on Whatever happened to the zero waste movement?
Of course it's better this way. But I don't see it possible for everyone as it's not compatible with big cities.
logtempo··on Whatever happened to the zero waste movement?
You buy cucumber that might have left the crop since +20 days already.
logtempo··on Whatever happened to the zero waste movement?
The cucumber plastic is really helpfull to not loose too much cucumber, it prevent dehydratation, this way it can last almost a month. And losing cucumber mean you are wasting fuel on all the "processing" and transport.

That said, a change in the process is possible, which prove your point of "individual change is near-impossible and pointless".

logtempo··on Shein forces Amazon to lower seller fees
It popped everywhere. I'm from europe, I was in Bolivia in october. Shein was the new trend. In Bolivia. In an open market of second hand.

My guess is tiktok is doing what it's made for, advertising and possibly putting China first to the mass of consumers.

logtempo··on Plastic is now a geological phenomenon
Good thing is, maaybe, maybe, plastic merging to rock will decompose less into microplastic and will be bury into sediments layers, eventually showing again in millions years.

But we'll probably never know, as permafrost is melting under +5°C increase in Arctic regions. Which is a ticking bomb in term of co2 release.

logtempo··on Plastic is now a geological phenomenon
Large plastic end up smaller and smaller over time. Also microplastic mostly come from clothes and tires.
logtempo··on Some Mexican pharmacies are selling full bottles of Adderall. But it's meth
In Bolivia, I was amused by the plastic bag they gave me for my meds that was advertising: "zero counterfait guaranteed".

At this moment I realized how far we went in wealthy countries, in my case Europe countries, in the regulation of drugs.

logtempo··on Python, C, Assembly – Faster Cosine Similarity
Could be spanish too :)
logtempo··on The "Cheap" Web
By the liberalism/capitalism definition: anyone can make its website, its app, its blog etc.

Which is the opposite of "we need an official social network" intervention

logtempo··on Making my own bed sensor
matress are around 40, maybe 50kg/m3.

water is 1kg/dm3, and acording to this website (https://www.aqua-calc.com/page/density-table/substance/human...) human is arround 1000kg/m3 which make sense.

So, yes matress is light compared to human, I guess it does nothing to the sensor pad.

logtempo··on Finally We May Have a Path to the Fundamental Theory of Physics
I'm not an expert at all, but I think the "one model to rule them all" is an sf problem that no serious physicist really work on...because rules are models to describe the universe. Knowing a unique model that match exactly means we are able to know everything about the universe. But how one can know that there is no more phenomena to be discovered, and that all models match exactly ?
logtempo··on The "Cheap" Web
States like to control, internet state of mind is 100% liberal, and both live in a capitalist world. Internet won its freedom, but freedom did not overcome the greed from capitalism.

Good news is you can still go to mastodon, after all.

logtempo··on Python, C, Assembly – Faster Cosine Similarity
Remind me of an article about the opimization of matrix calculus with IA, that eventually shown better algorithm for specific size of matrix, than the one found decades ago and proven to be the best one.
logtempo··on 'A-team' of math proves a critical link between addition and sets
Ho, that's really cool! Sounds a bit like digging your own grave as mathematician but it must be very challenging
logtempo··on BrainGPT turns thoughts into text
Yes, there is a part that is under the skull, if I understand it correctly ("at the surface of the cortex"). It claims to be the first success in the world, so it is indeed impressive! https://youtu.be/6Ee3kZIW5fk
logtempo··on BrainGPT turns thoughts into text
Recently, a Swiss-French team made the communication between the brain and the legs possible, and the device looked relatively mature. I think patient had nerves damaged in the vertebral column. What do you think about it ? Looked like a promising development.

logtempo··on How Africans are changing French, one joke, rap and book at a time
it's certainly interesting. Imo music, and especially the rap by its generally large young audience and creativity is and have been a huge "influencer" of French.

I think the article fail a little bit to put in perspective other influences, and even more when the title say "Africans" when it focus on west and central Africa only. Africa is a continent that don't talk only French, North Africa is part of Africa too, and arabic countries do have an influence too. So, no more bad title please.

Also, it's interesting to think that initially, "True" French was imposed by the state, and by law, in France, that led to the end of local dialects. I just hope that it will not happen in reverse in some africans countries, as pointed out by the article...People should remain free of speech, in whatever languages they want to use.

logtempo··on Apple introduces spatial video capture on iPhone 15 Pro
And I bet an other Avatar movie with Apple money
logtempo··on The Onyx Programming Language
I believe general purpose tool will atract people with general knowledge, so more people. Very specific dev will atract experts, so less people will engage to the work.
logtempo··on 'A-team' of math proves a critical link between addition and sets
Yesterday I was wondering if it's possible to have an AI that can "recreate" the mathematics as we know it, and even go further and explore unexplored paths.

Though prduced by a video explaining how AI helped to find optimization in the computation of matrix multiplication.

logtempo··on Coding Addiction: How Programming Affects Your Brain
There is zero knowledge in this article.
logtempo··on Ask HN: What side projects landed you a job?
you do side projects! More seriously, I'm exactly in this situation and you'll have to find transversal skills, often soft skills when it' very different. And side projects, or courses.

And accept a junior position, even if you're a senior dentist.

logtempo··on Ask HN: What side projects landed you a job?
Did a similar thing. I did a cubesat internship at some university (different from where I was), which played a role in getting a master and then an other internship at a lab working on a part of a scientific satellite to study Jupiter's moons (launched in 2023!).

And so on. It's crazy how pushing a series of little things can put you on the right path, especially early on life.

logtempo··on New York will plant trees using new tech to maximize foliage impact
In France, they started planting trees along the road during Napoleon era, so the soldiers could walk at the shadow of the trees. Definitly smart, but also very old idea ahah

That said, with the car development, they cut most of the trees because well...a car hitting a tree is not good.

logtempo··on Electrocaloric material makes refrigerant-free solid-state fridge scalable
There are very small batteries that use the changes in its environments, but it use in general vibration, or light, or sugar (see https://en.wikipedia.org/wiki/Sugar_battery). But the power is very small, used for very low power devices. One could think to use the sun cycle (become a little bit warm, then a little bit colder during the night), but at this point solar panel do the trick.
