teruakohatu··on Reflections on 2 years of CPython's JIT Compiler
The article points out they have only begun adding optimisers to the jit compiler.

Unoptimised jit < optimised interpreter (at least in this instance)

They are working on it presumably because they think there will eventually be a speed ups in general or at least for certain popular workloads.

teruakohatu··on Why are there still 7 continents?
There are a variety of definitions, and for a number of definitions my country hints at claiming an entire “continent” [1] Not actually pressing a claim diplomatically but also not dismissing the idea of a claim.

Of course there is zero chance New Zealand would ever challenge Australia or France for territory, and little chance we could ever claim economic rights.

teruakohatu··on Price of rice in Japan falls below ¥4k per 5kg
Are those “>” greater than signs or arrows?

Neither English nor Indian and I would rate Naan bread right at the top if I had a choice.

teruakohatu··on Cloudflare to introduce pay-per-crawl for AI bots
All the LLMs are being trained on LibGen/Anna’s Archive so it’s not in the least surprising they can tell you about papers behind paywalls.

But I don’t think they are creating accounts to scrape paywalled data from the original source itself.

teruakohatu··on Price of rice in Japan falls below ¥4k per 5kg
I am not Japanese, and don’t eat a lot of rice (twice a week maybe), but I don’t think it’s madness.

If you told me to eat rice instead of bread I would probably be just as horrified

teruakohatu··on Price of rice in Japan falls below ¥4k per 5kg
> As mentioned, I've done taste tests across various options and I can definitely tell the difference, which is why I pay more.

Can you tell the difference between Japanese brands or only between Japanese and non Japanese origin rice?

Is rice a significant percentage of food cost in Japan? Coming from a culture that uses less rice, the cost of price verses the cost of protein makes it just about a rounding error when cooking.

Now butter on the other hand has just about become a luxury good in New Zealand when it was once cheap, plentiful and extremely high quality.

teruakohatu··on DeepSeek R2 launch stalled as CEO balks at progress
Releasing the model has paid off handsomely with name recognition and making a significant geopolitical and cultural statement.

But will they keep releasing the weights or do an OpenAI and come up with a reason they can't release them anymore?

At the end of the day, even if they release the weights, they probably want to make money and leverage the brand by hosting the model API and the consumer mobile app.

teruakohatu··on DeepSeek R2 launch stalled as CEO balks at progress
The title of the article is "DeepSeek R2 launch stalled as CEO balks at progress" but the body of the article says launch stalled because there is a lack of GPU capacity due to export restrictions, not because a lack of progress. The body does not even mention the word "progress".

I can't imagine demand would be greater for R2 than for R1 unless it was a major leap ahead. Maybe R2 is going to be a larger/less performant/more expensive model?

Deepseek could deploy in a US or EU datacenter ... but that would be admitting defeat.

teruakohatu··on Define policy forbidding use of AI code generators
So essentially it’s “let us cover ourselves by saying it’s not allowed” and in practice that means not allowing code that a human thinks is AI generated code.

Universities have this issue too, despite many offering students and staff Grammarly (Gen AI) while also trying to ban Gen AI.

teruakohatu··on BYD begins testing solid-state EV batteries in the Seal
> It's actually gotten worse because more EVs are on the road and the chargers haven't kept pace with the rising demand.

It is curious that this is the case. If chargers were profitable a couple of years ago, you would expect more chargers and more profit today.

I haven’t noticed much growth in chargers where I live but I have noticed more EVs on the road.

teruakohatu··on AbsenceBench: Language models can't tell what's missing
> Here are two verses of a poem (song) in Mandarin Chinese:

> …

> I removed two lines. Where did that happen?

If you read the paper you will see they provide the original as well as the version missing information.

I did mention this in my comment too.

I am quite sure I could find your two missing lines if you provide me the full poem.

Given that you are a prolific commenter on HN, I am sure a LLM could be fine tuned to detect missing text from your comments without additional information. For example …

> WinForms is still around. There have been further tec lly just a big tire fire and about the best you can do is to ignore all of them and develop in WinForms.

It’s probably possible to detect missing information from “tec” until “lly”. But to know what is between is not possible for a human either, beyond plausible guesses.

teruakohatu··on Tuxracer.js play Tux Racer in the browser
This works really well on mobile. Kudos to the author.
teruakohatu··on AbsenceBench: Language models can't tell what's missing
> When looking for an omission, that omission can be anything,

In this benchmark they give the LLM the necessary information to determine what is missing. For example “here is a poem, here is a version of that same poem that may or may not be missing lines. Are any lines missing?

It’s more a tuning issue IMHO than an inherent weakness in LLMs.

If I was asked to find an omission in an ML paper, my brain compares it with other ML papers, it does not need to compare it to Star Ward, Top Gear, Greek history, pottery and the other 1000s of contexts I may know about.

teruakohatu··on David Attenborough at 99: 'I will not see how the story ends'
I can understand there is an inherit sadness in not knowing the outcome of one's life's work, but as you say none of use ever see how it ends. In terms of our natural environment humankind has only ever observed in person, let alone recorded, what amounts to the blink of an eye.
teruakohatu··on Have a damaged painting? Restore it in just hours with an AI-generated “mask”
Looking at a oil painting in real life is a vastly different experience than a looking at a print. Oil paintings are for a start 3D (textured). Colour reproduction is also difficult.
teruakohatu··on AI agent startups at Y Combinator’s Spring ’25 Demo Day
> For coding, this has started to happen and it's in full swing, what about other domains?

There needs to be a moat. I see all these startups with a moat that is no bigger obstacle than a puddle.

A local (geographically to myself) pre-LLM (Convolutional Neural Network) company invested in a huge moat, building a large training set of human labeled data ... I knew the moment I saw an LLM that could ingest image that their moat had evaporated in an instant. A lot of the technical staff either left or lost their jobs but the company appears to be limping on hoping for an exit.

If a startup depends on a secret prompt and a few MCP servers, they have no moat.

I think the next wave of AI-based SaaS (rather than pure AI API providers) will be companies like the Legal IDE (Tritium [1]), recently featured on the homepage. Tools that innovate and use AI, but would still be innovate even without it.

[1] I have no affiliation whatsoever. I just liked the demo and the concept.

teruakohatu··on Anne Wojcicki to buy back 23andMe and its data for $305M
Wojcicki's non-profit "TTAM Research Institute" domain was registered last month [1] and the current Powered by GoDaddy landing page went online around 5 June. [2]

Anyone know if its a legitimate non-profit or one of the "sort of" non-profit?

From the press release [3] ...

> TTAM Research Institute (“TTAM”), a nonprofit public benefit corporation based in California ... The TTAM Research Institute is a nonprofit medical research organization dedicated to helping scientists and non-scientists join together to unravel the mysteries of DNA - the code of life. TTAM believes everyone should have the opportunity to access their individual genetic code and be empowered to contribute it to scientific research. The TTAM Research Institute was founded and is led by Anne Wojcicki.

teruakohatu··on I convinced HP's board to buy Palm and watched them kill it
I think it is better to be charitable. I think he does genuinely believe what he wrote is what happened. His PDF book is free and Creative Commons.

There could be many reasons he waited this long. Maybe he waited until he was retired and would not face blowback. Maybe he just has some free time.

It is very plausible that WebOS could have been an equal peer to iOS and Android. CEOs have killed off projects that might have been great commercial successes while perusing short term gains.

In a decade's time we might hear a story from inside ATI or AMD how they killed off their chance of beating CUDA for short term gains.

teruakohatu··on OpenAI o3-pro
Do you think a cycling pelican is still a valid cursory benchmark? By now surely discussions about it are in the training set.

There is quite a few on Google Image search.

On the other hand they still seem to struggle!

teruakohatu··on OpenAI dropped the price of o3 by 80%
Can you explain? Is it not actually free?
teruakohatu··on Containerization is a Swift package for running Linux containers on macOS
> How hard is it to emulate linux system calls?

It’s doable but a lot more effort. Microsoft did it with WSL1 and abandoned it with WSL2.

teruakohatu··on Google battling 'fox infestation' on roof of £1B London office
The article says they are digging barrows. I can understand that when a company spends an exorbitant amount of money on a building with a roof garden and the costs of ongoing maintenance they are not happy it is being dug up, especially if they are digging down to the water barrier.

On the other hand I think it is pretty cool to have foxes on the roof.

teruakohatu··on Apple announces Foundation Models and Containerization frameworks, etc
> Every Apple Developer Program membership includes 200GB of Apple hosting capacity for the App Store. Apple-Hosted Background Assets can be submitted separately from an app build.

Is this the first time Apple has offered something substantial for the App store fees beyond the SDK/Xcode and basic app distribution?

Is it a way to give developers a reason to limit distribution to only the official App Store, or will this be offered regardless of what store the app is downloaded from?

teruakohatu··on Apple introduces a universal design across platforms
Looks like Apple (re)discovered Sun's Project Looking Glass from 2003.

https://en.wikipedia.org/wiki/Project_Looking_Glass

Liquid Glass looks a lot like coming up with changes for the sake of them.

teruakohatu··on I'm Wirecutter's water-quality expert. I don't filter my water
> Anyone who trusts their municipal water supply because of handwave regulations and reports needs to read that again.

A better approach is to decide whether your municipality meets or exceeds guidelines (the 85% that do).

I trust my city (in New Zealand), but there are other cities I wouldn’t because their water infrastructure is old and under funded, or because of known problems in the recent past.

teruakohatu··on Supreme Court Gives Doge Access to Social Security Data
Can I ask why in the USA can a malicious individual with a random person’s SSN number and name allow them to wreak havoc?

In my country we just have a name but you need an ID document to get anything done.

Do banks etc. consider an SSN number to be a password?

teruakohatu··on Deep learning gets the glory, deep fact checking gets ignored
> Like giving GPT a multiple-choice test on gibberish—it will pick something, and say it with its chest.

If I gave a classroom of under grad students a multiple choice test where no answers were correct, I can almost guarantee almost all the tests would be filled out.

Should GPT and other LLMs refuse to take a test?

In my experience it will answer with the closest answer, even if none of the options are even remotely correct.
