weebull··on The MacBook has a sensor that knows the exact angle of the screen hinge
My framework 12 has a similar sensor. It tells to UI when to disable the keyboard and track pad because you've got it in tablet mode.

Microsoft is still supporting them by supplying $10bn in compute resources at cost. That's a huge recurring investment.

A lot of people correlate it with humans moving from a vegetarian diet to a omnivorous diet.

1. Higher nutrition levels allowed the brain to grow. 2. Hunting required higher levels of strategy and tactics than picking fruit off trees. 3. Not needing to eat continuously (as we did on vegetation) to get what we needed allowed us time to put our efforts into other things.

Now did the diet cause the change, or the change necessitate the change in diet... I don't think we know.

Absolutely. All the talk around AGI being some barrier through which unheard of glories can be unlocked sound very much like "perpetual motion machine" talk.

China is not decarbonising. It's emissions are rocketing up.
weebull··on Ask HN: Anyone else tired of AI being forced on you?
> Yes, but you placing your neck under that boot is a free choice.

Bollocks. We're not talking about going to a chat bot and asking questions. That's a free choice. It's insertion into every facet of online life is unavoidable and far more destructive.

weebull··on Alan Yentob Has Died
I remember him as a high level BBC executive in charge of programming, but I believe he was a presenter for a long time before that, concentrating on documentaries and journalistic pieces, particularly on the arts. He had a reputation of being very good at what he did, and I believe the period he was in charge is seen as a bit of a golden era for the BBC, especially for those not from the classical Oxbridge background.
weebull··on U.S. national-security leaders included me in a group chat
He might serves his country better by waiting for them to incriminate themselves more.
weebull··on Athena spacecraft declared dead after toppling over on moon
In 1969 they used a pilot, and a very good one too.

Surveyor 1 in 1966 is a much better comparison.

weebull··on AI tools are spotting errors in research papers
Exactly. That's why sigh.
weebull··on Mark Cuban offers to fund former 18F employees
Never rejoin under somebody that's already fired you. They are being forced to do it and will fire you again at the first chance.

Only go back if the management has changed. In this case, that means "If doge is gone".

weebull··on Colossus, the first large-scale electronic computer
Not uncommon. Collosus was classified for 50 years. All examples were broken up and destroyed along with all the plans by order of Winston Churchill. After it was declassified years later, the few people that knew about it set about rebuilding it from whatever fragments of information they could scrape together through old notes that had survived and interviews with the original team. Flowers (the designer) was still alive at the start of the project, but I don't think he lived to see it working.

Apparently, when Collosus became public there were talks given where the Americans who worked on ENIAC (I think) were stunned to find that the British had solved a lot of the same problems they faced just before them. It was an extremely closely guarded secret.

weebull··on Colossus, the first large-scale electronic computer
> I think the main innovation was the use of valves (similar to tube logic), while other machines of the day used relay logic.

Vacuum tubes and Thermionic Valves are the same thing. "Tubes" is the name that stuck in the states. "Valves" in the UK.

> This thing wasn’t really a computer though, in that it was not turing complete,

Turing completeness isn't a requisit to compute. Tommy Flower's big step was taking the electronic switching technology used in telephone exchanges and applying it the computation. Others said that they would be unreliable with the switching speeds involved and mechanical switches were the only way to do it. Flower's knew the key to reliability was thermal stability and designed his machine.

> > These first turing complete machine that “worked” was probably the Z3 from 1941.

No, it didn't have a condition branch. Z4 had that, but after ENIAC did.

weebull··on Ask HN: What is interviewing like now with everyone using AI?
So if you were to do a transformation like that you'd cut the code and paste it into a new function. Then you'd modify that function to make the abstraction work. An LLM will rewrite the code in the new form. It's not cut/paste/edit. It's a rewrite every time with the old code as reference.

Each rewrite is a chance to add subtle bugs, so I take issue with the description of LLMs "working on existing code". They don't use text editors to manipulate code like we do (although it might be interesting if they did) and so will have different issues.

weebull··on Anthropic: "Applicants should not use AI assistants"
Homework problems are normally geared to the text book that is being used for the class. They might take you through the same steps, developing the knowledge in the same order.

Using another source is probably going to mess you up.

weebull··on Another undersea cable damaged in Baltic Sea
80m is moderately serious. I've personally done 75m in the Atlantic and I wouldn't say I'm superhuman or anything (or military).

It requires helium mixes and personally I'd only want to do it with a rebreather, not normal "blowing-bubbles" type SCUBA gear (too wasteful on the breathing gas). 20-30 minutes at the bottom will mean around 90-120 minutes decompressing. You don't want to be doing anything taking too long, or being too laborious.

Could be done from a fishing boat without any problem.

weebull··on Another undersea cable damaged in Baltic Sea
It's electronic signals warfare. Depriving your opposition of power or communications destabilises command structures.

Now you might say "...but these cables are so low value", but these are easy targets that reduce the resilience of the Baltic states. Any more conventional attack would now be more effective because they've taken the backups out first.

weebull··on Meta is killing off its AI-powered Instagram and Facebook profiles
Mainly because they ousted Lassiter for being to critical of the crap that was being put in front of him. They framed it in other ways publically, but I'm pretty sure he was getting in the way of others taking the company in a direction that didn't prioritize quality.

weebull··on Why are UK electricity bills so expensive?
> China, one is the most polluting non-western countries, is going to renewables and electric vehicles at a faster rate than some of the western countries.

Its not "going to renewables". It's building the fastest amount of renewable generation, but that's new capacity, not replacement. It's also building the most coal plants and nuclear plants and anything else. It's all new capacity.

Same with cars. Most EVs and most ICes.

China is growing, and is doing so in all directions.

weebull··on Why are UK electricity bills so expensive?
I don't think it's a particularly cryptic measure.

The UKs peak carbon per kWh was at some point. Since then it's dropped at a percentage rate higher than anywhere else.

The biggest thing has been the elimination of coal even if it's with natural gas as it's a much cleaner fuel. It's still a fossil fuel, but burns with much less pollution.

weebull··on Infamous paper that popularized unproven Covid-19 treatment retracted
"Responsible" or "irresponsible" is not a valid criticism of a scientific paper. Those words have no part to play in the search for facts.

The biggest way that I think the reputation of the science community is being harmed is that it's not holding true to it's own tenets. The only way to discredit a paper is to falsify it's claims. Not to call it "irresponsible" or "immoral", label it "disinformation" or "pants-on--fire".

Bad science gets proved wrong, but nobody is interested in reproducing results. As a result our journals are full of accepted papers documenting unreproducible crap. They have been for a long time. When COVID hit and we needed science to be clean and authoritive, it was already in disarray. Unable to tell us what actually worked, we just got a bunch of folklore from all sides some of which got "blessed" by the high priests and some which was "sacrilegious", but very little of it was backed up with any data beyond modelling (which is just predictions).

Nobody should be claiming the high ground w.r.t. COVID IMHO. The science community failed us by acting in response to politics and not science.

If you can write a program to check results you've already solved the issue.

I'm not.

Whoa there Nelly!

If we're going to resurrect things, can we do it whilst leaving PHP in the past?

weebull··on Solving Advent of Code at compile time with Rust macros
It's full of stupid comments. E.g. the python implementation has this attached.

```py """Warning: This code completes in a shocking O(n log n) time complexity and allocates memory with reckless abandon""" ```

How shocking that sorting is an O(n log n) algorithm.

Edit: he then goes on to use bubble sort.

I think there might be a large amount of tounge in cheek with this blog post, but it doesn't really land.

weebull··on Goodbye, Rust. I wish you success but I'm back to C++ (sorry, it is a rant)
One of the things I loved about Python when I learnt it was how it dealt with `public`\`private`\protected``. It was "we're all responsible adults. No need to hide anything. We'll just use a naming convention for members that we don't expect people to directly use."

"Enforce encapsulation" suddenly became. "Respect encapsulation" in my head and a bunch of Java/C++ problems evaporated.

weebull··on Intel might be too big to fail
If it dies, hundreds of companies will rise from it's ashes. One of the big problems America has is the tech giants hoovering up all competition. The 70s,80s and 90s weren't boom times because of the fact these tech giants got their break at that time. It's because the market still had 5-7 major semiconductor companies. Fairchild, Motorola, TI, Intel, Zilog, and that's without really thinking about it.
weebull··on Unix core utilities implemented in Haskell
Lazy to strict is reasonably easy to do though. The problem is normally that once one bit goes strict, most other things implicitly do too.

Strict to lazy is normally a rewrite.
