amazingamazing··on BYD's Five-Minute Charging Puts China in the Lead for EVs
still don't get the point of huge batteries. in USA average commute is about 20 miles one way. seems like a 75mile battery + gas is both more practical and requires less infra.

edit: it seems some are confused. I'm saying a PHEV is superior to BEV.

amazingamazing··on 60–70% of YC X25 Agent Startups Are Using TypeScript
Makes sense - for front-end there's really no alternative. For back-end node.js is more than fast enough for pretty much any startup.
amazingamazing··on The Right to Repair Is Law in Washington State
> That means no more pop-ups that say “unknown part” when you swap in a working screen. No more downgrading your camera or fingerprint sensor just because you repaired your own phone.

I'm curious if that means that it's now illegal for the company to tell you if you have a device with fake parts.

I also don't quite understand the security implications. If you need some attested part, like a TPM, and this and some other thing like a fingerprint sensor fail and you replace them both, you cannot disable the fingerprint sensor since now technically it cannot attest itself?

amazingamazing··on Conformance checking at MongoDB: Testing that our code matches our TLA+ specs
interesting article - I wonder why TLA+ isn't more popular. seems useful, but I guess it's hard to iterate fast with it.
amazingamazing··on Codex CLI is going native
> And now everyone is rewriting everything in Go/Rust left and right.

Seems like confirmation bias.

amazingamazing··on Mary Meeker's first Trends report since 2019, focused on AI
What about the ones they were right about?

Is it profitable though? I do agree that employers may pay, but it’s unclear to me at least if it is profitable for them either.
amazingamazing··on Mary Meeker's first Trends report since 2019, focused on AI
Did a quick search for profit: nada.

I am genuinely curious if lay people will pay for AI. I know people who spend literally hours daily on YouTube and complain about the ads and don’t want to pay the quarter a day to get rid of em.

Will these people pay $50 a month for gpt? We will see.

amazingamazing··on Systems Correctness Practices at Amazon Web Services
ah, yes.

Trust me, I love FDB, but that's not the same thing. The FDB team IIRC had to write their own programming language to do this. It's not a agnostic layer above the application.

The problem with coupled tooling is that no one will use it. That's what is cool about antithesis. If they're able to complete their goal, that's basically what will be achieved.

> Deterministic simulation. Another lightweight method widely used at AWS is deterministic simulation testing, in which a distributed system is executed on a single-threaded simulator with control over all sources of randomness, such as thread scheduling, timing, and message delivery order. Tests are then written for particular failure or success scenarios, such as the failure of a participant at a particular stage in a distributed protocol. The nondeterminism in the system is controlled by the test framework, allowing developers to specify orderings they believe are interesting (such as ones that have caused bugs in the past). The scheduler in the testing framework can also be extended for fuzzing of orderings or exploring all possible orderings to be tested.

Any good open source libraries that do this that are language agnostic? Seems doable - spin up a container with some tools within it. Said tools require some middleware to know when a test is going to be run, when test is run, tools basically make certain things, networking, storage, etc "determinstic" in the context of the test run.

This is more-or-less what antithesis does, but haven't seen anything open source yet.

You of course, could write your tests well, such that you can stub out I/O, but that's work and not everyone will write their tests well anyway (you should do this anyway, but it's nicer imo if this determinism is on a layer higher than the application).

as a slight sidebar - I'm not really bullish on AI, but I think testing is one of the things where AI will hopefully shine, because the feedback loop during prompting can be driven by your actual application requirements, such that the test implementation (driven by AI), requirements (driven by you as the prompt) and "world" (driven by the actual code being tested) can hopefully help drive all three to some theoretical ideal. if AI gives us anything, I'm hoping it can make software a more rigorous discipline by making formal verification more doable.

See my other comment about AI demand increasing. I never mentioned any other state lol… you are reading too much into it
amazingamazing··on California has got good at building giant batteries
what do other states have to do with anything?
amazingamazing··on FLUX.1 Kontext
is it mostly accurate though? how would you know? suppose you had an asian woman whose face is entirely covered with snow.

sure you could tell AI to remove the snow and some face will be revealed, but who is to say it's accurate? that's why traditionally you have a reference input.

Just in time for datacenters spiking AI usage to eat all of that peak time excess. Luckily the super scalers are some of the folks driving investment into this stuff.
amazingamazing··on Sam Altman and Jony Ive Will Force A.I. Into Your Life
Video aside, has there been any serious attempt to do everything with audio only?
amazingamazing··on Sam Altman and Jony Ive Will Force A.I. Into Your Life
you could do this by clipping a theoretically smaller phone onto your shirt right? or taking the current one and just putting it on a shirt pocket or equivalent
amazingamazing··on FLUX.1 Kontext
yes, so a stereotypical image. my point is best illustrated if you look at all of the photos of the woman.
amazingamazing··on FLUX.1 Kontext
I get that but usually you would have two inputs, the reference “true”, and the target that it to be manipulated.
amazingamazing··on FLUX.1 Kontext
Don’t understand the remove from face example. Without other pictures showing the persons face, it’s just using some stereotypical image, no?
amazingamazing··on ClickHouse raises $350M Series C
Interesting - hardware is so cheap though, I guess most enterprises don’t want the hassle.

Personally I’d just go to a colo center buy a rack of super micro and call it a day. No way that’s more expensive after a year (per public pricing).

amazingamazing··on ClickHouse raises $350M Series C
How hard is it to self host clustered clickhouse? Is there parity with the hosted offering?

amazingamazing··on The effect of physical fitness on mortality is overestimated
You live closer to work?
amazingamazing··on The effect of physical fitness on mortality is overestimated
I’m skeptical that it’s worth it to spend too much time working out.

If there are three options:

1. Sedentary lifestyle (<3 passive or active exercise weekly).

2. Moderate (~1 hour passive exercise daily, like walking a dog a few miles daily).

3. Active (>1 hr active, like running several miles or lifting).

I think there’s huge value in moving out of (1), but am not sure if it’s worth going from (2) to (3) w.r.t longevity

amazingamazing··on Solar grants held hostage in Pennsylvania legislature – as demand soars
Yes, that’s why any money given would be conditional like I mentioned…
amazingamazing··on Solar grants held hostage in Pennsylvania legislature – as demand soars
Seems better to give the money to electricity providers to install solar panels as solar farms and force them to discount electricity rates based off pre calculated solar electricity yield.
amazingamazing··on Show HN: Undetectag, track stolen items with AirTag
You could say the same with a lock. Do you care once it’s broken?
amazingamazing··on Show HN: Undetectag, track stolen items with AirTag
You’re proving the other persons point - the reason why the a thief doesn’t trivially pick locks isn’t because of the lock, it’s because it’s illegal and there’s a consequence.
