Torkel··on Tokyo by Train (2016) [video]
Same with EU-issued visa cards! As I learned when visiting in July.

You can charge up the iphone suica balance using cash in the machines... a bit weird but that's what I did.

Getting back home first thing I did was get a mastercard to complement my visa, as it seems EU mastercards still works to charge Suica.

It would be interesting to read about why this happened, it feels like there are interesting payment processing details to learn from it :)

Torkel··on Andrew McCalip demonstrates synthesis of LK99
From a scientific perspective, you are probably correct.

But think about it from a company/wealth creation perspective. Are you then really sure the correct course of action is to take it chill?

Torkel··on Andrew McCalip demonstrates synthesis of LK99
As engineers we are given building blocks that we can build things from. Iron, steel, copper, plastic. Every once in a while a new building block arrives. It takes a while for us to figure out how to use it. But when we do, the world changes.

- batteries + touch screens => iPhone

- batteries got better => Tesla

- reinforced concrete => pretty much all the worlds buildings and bridges

- neodymium magnets + gyros => drones

A room temperature superconductor... well, that changes things on a completely new level. Order of magnitude smaller losses plus order of magnitude higher magnetic fields? OMFG can we build SciFi things from this if it pans out.

So yeah - we are in a hurry. If this pans out, there will be a massive shift in how pretty much anything is made. And the reward for the people who can figure it out first are insane, in terms of potential value created.

Torkel··on Some remarks on possible superconductivity of composition Pb9CuP6O25
First steps of how LK99 could be used - embed superconducting nanocrystals into things. Given how insanely much metals we use for conductors I think it will be quite a while until this sees any kind of mass usage. But wow what an industrial investment boom we would be part of if LK99 actually works.

I also think it is very interesting that this entire class of superconductors will, as far as I can tell, be illegal in the EU for most application due to RoHS:

Torkel··on Building Nikola Tesla's Bladeless Turbine [video]
It’s so fun to watch these builder-youtubers develop over time.

If they just keep on releasing videos and building stuff, even if they are not so skilled in the beginning eventually they become really skilled! It really shows that practice yields mastery.

Tom Stanton is another on my list.

Torkel··on Sappers risk their lives to win Ukraine back, inch by inch
The list is INSANELY long.

Most multinationals seem to be operating on a "business as usual" principle in Russia.

If they all risk jail time, things will be different.

Also consider that any purchases of anything from Russia would now also be classified as sponsoring terrorism. So no more Gasprom gas :P

Torkel··on Sappers risk their lives to win Ukraine back, inch by inch
Yeah - that seems to be about Russia being a state sponsor of terrorism (e.g. https://www.europarl.europa.eu/news/en/press-room/20221118IP...)

But what I would like to see is a situation where companies paying tax to Russia are seen as sponsoring terrorism. It would have insane reprecussions?

Torkel··on Sappers risk their lives to win Ukraine back, inch by inch
So, are they terrorists you say?

Well, then.

Classify them as such.

=> Any funding of them is now funding of terrorism. Including paying tax in Russia. Which means any and all companies doing business in and with Russia, and the individuals working in and for those companies now have to immediately stop, or else face jail... right?

Seems like it could be super effective way of halting Russia?

Torkel··on Threads, an Instagram app
1. The people who are possible users of something like this are already on Twitter. The target audience is not all of Facebook, so not 10x.

2. I have seen data that can be used to argue Twitter is slipping. But to claim Twitter is dying is a great exaggeration, based on data. There are perhaps cases where a company will totally mess up something and a replacement can take over, but this doesn't seem to be it.

3. Well, hard to tell. To me the geek information bubble is the conviction that Twitter is dying. Also, I think Zuckerberg is a lot more famous that you account for. But I could not find data on it.

Torkel··on Threads, an Instagram app
I don't get this at all. To me it seems like it will obviously fail.

1. Twitter is all about who is there. How will they make people start posting on this?

2. New platforms take off because they innovate, not because they do what others do but slightly tweaked.

3. I have a really hard time seeing people mass escaping twitter to this du to morals. Facebook/Zuck is just as reviled as Twitter/Musk. If not more reviled. Mastodon has the moral high ground, but still can't take off.

Torkel··on Turn ideas into music with MusicLM
Last one is much better than I expected this thing could do!

Torkel··on Rimac Energy: Stationary Energy Storage Technology
Yeah - it's weird they don't say it.

Assuming it's batteries though, since the company makes battery electric cars.

Torkel··on Alien Artefacts
I agree with many comments here but especially with this - the domains these alien artefacts touch are the things that makes them so tricky. Nonlinear optimization is one such area I work with regularly.

It seems there is an analogy to python and web programming here - a lot of people can work with things in python/js that are like alien artefacts to them.

Are some areas more prone to alien artefactness than other areas? What about deep learning - how many folks doing it actually understand things vs just use neatly packaged alien artefacts?

Torkel··on Lithium battery ripe for disruption, inventor says
Disrupting lithium for batteries is like disrupting silicon for transistors - sure there are niches and areas where other things, like silicon carbide or gallium can be used! But to any one trying to pour money into something competing with the trillions of dollars invested into the existing techniques I say: good luck with that.
Torkel··on The Coming of Local LLMs
Things are moving so fast in this space I felt like I needed a [March] in the title on this one :)
Torkel··on Programmer interrupted: The cost of interruption and context switching (2022)
Reading through the comments here, and in the ton of similar threads on this subject, I feel I must be such an outlier...

For me there are different tasks and different days. Some days I want uninterrupted flow. But some days I feel more productive by chopping it up with a few meetings and some office trash talk. A laugh every now and then, teasing a co-worker for screaming at his code - it gives energy to me. Talking through a problem or pausing for a while in a meeting and then returning to it - that can be a great way to see new things.

Now don't get me wrong here, I am not saying meetings and distractions are good for everybody. But it's just that for me at least the picture is not as clear. Some days I feel I would have been more productive if I had had some meetings to distract me.

Am I really the only one to feel this way?

Torkel··on GitHub slashes engineering team in India
Long term we should all be worried. Or hopeful? It is unclear to me if it is a blessing or a curse to have what one loves doing revolutionized... I am actually leaning towards blessing. At least if the goal of programming is passion for building. And this gets to your other point: if what a programmer does is direct implementation of requirements, in a mechanical fashion, without any consideration other than passing some requirements set off in a PRD... then yes, I would replace that. We have discussed this internally, and the way we work an LLM will be a tool not a replacement. So our employees are safe. For now.

As for FAANG layoffs - I think it is happening all over, but also that it is overreported. The graph of hires over the past few years should be references whenever number of people layed off is mentioned. Over the past 1-2 years I think the tech giants are way up in head count.

Torkel··on GitHub slashes engineering team in India
That was my thought too. The outsourcing teams that aid in development require specifications and documentation. "Code factories" feels like a target for LLM-replacement.

Perhaps there's a startup idea here: identify the way communication is done with these teams (PRDs? I have no idea...), and create a service that takes that as input and creates results using LLM? There for sure should be room for fine-tuning models for it, as well as learning to have the LLMs create and run tests for all the code, according to requirements/specs.

Torkel··on OBS Studio Lands AV1 and HEVC RTMP Streaming Support
Nice! That looks great!, didn't know about it.

The hardline opposition to adding hevc etc support to rtmp came from ffmpeg+gstreamer afaik, and from the document it looks like at least ffmpeg is on board.

...Might have to brush off our broadcast software and add this :)

Torkel··on OBS Studio Lands AV1 and HEVC RTMP Streaming Support
A "fun" thing here is that it isn't possible to create or open these streams in ffmpeg due to neither hevc or AV1 being part of the Adobe RTMP standard. At least as per this thread:

Torkel··on Transformer architecture optimized for Apple Silicon
2022?

Latest commit seems to be "on Aug 9, 2022"

Torkel··on ChatGPT is Down
Mouse over text: "Wikipedia trivia: if you take any article, click on the first link in the article text not in parentheses or italics, and then repeat, you will eventually end up at "Philosophy"."

I find that this is no longer working. But I also remember it being reliably working at the time of first reading this. Anyone know when/why it "broke"?

Torkel··on Symbolic Discovery of Optimization Algorithms
Yeah, the acronym is very far fetched…

But at least the algorithm and how they got to it seems dope.

Torkel··on The Broom Method
Interesting in a ”the russians used a pencil” way, but the text confused me by talking about hydrogen _leaks_ being detected this way. Surely brooms can only indicate hydrogen _flames_.
Torkel··on Toroidal propellers turn your drones and boats into noiseless machines
Wow. Anyone making these for drones yet?

This will be big.

Torkel··on Rust's Ugly Syntax
I care a lot about how nice my tools are. Beauty is for sure important in all human endeavours.
Torkel··on VR robots are building railways in Japan
Teleoperation in VR makes a lot of sense for some applications. E.g. when you want stereo vision for relative positioning. Here’s the same thing but for timber loading:
