> In fact, one of the first test boards the team plugged the ARM into had a broken connection and was not attached to any power at all. It was a big surprise when they found the fault because the CPU had been working the whole time. It had turned on just from electrical leakage coming from the support chips.

So this not an urban legend after all, and it's about the first ever ARM CPU! Very cool story indeed

Repeating the oft-cited but questionable assertion that car companies dismantled city rail systems makes me uncertain about how trustworthy the rest of their claims are. Though they did mention that the US is the most wealthy nation in the world -- did they later offer an opinion whether that would still be true had we approached public transit and health care subsidies the same way European countries did?

I simultaneously feel repulsed by AI music and "art" and yet am totally open to being captivated by AI music if I really feel something is musically better than almost any human-made music I've heard.

I just haven't heard anything that isn't "slopful" yet. If I do, I will still feel weird about it, but I'm a big believer in the value of "aesthetic objects in themselves", so I am eager to find something I do actually like.

Even just knowing something was drawn or composed by an AI will negatively taint my opinion from the start, but I'm still open.

That struck me, too. I listen to plenty of tech and car podcasts, so I'm quite used to people acknowledging their privilege in complaining about their latest $2000 gadget or the $600,000 car some manufacturer lent them to complain about for a week. I get it! When you're nit-picking a $600,000 car you can't afford, you're not saying it's worse than a Camry, but you're just pointing out the things that could be better. That's fine, but of course it will attract the haters in the comments.

But still, the note at the beginning of this one struck me. I'm not sure we need a warning on _every_ single article. If the warning served to keep the snarky comments away, great. But this is the internet. People are gonna snark anyway, so the caveat up front doesn't accomplish what one might hope it would.

Ever since I first looked at the Oshkosh NGDV for the USPS I couldn't help but wonder WHY there was a need for a custom vehicle?*

European parcel delivery firms and postal systems (Deutsche Post DHL, La Poste, Royal Mail, PostNL and all the non-legacy competitors) generally do not commission purpose-built vehicles, they buy off the shelf small vans and light commercial vehicles.

* of course I do know why, "because jobs and politics"...

> in urban areas, buses are pretty much the best possible use case for BEVs, aren't they?

I'd argue that mail delivery is an even better use case - it starts and stops even more frequently than a bus, practically never needs to travel at high speeds, and only needs to make one run a day.

But it's not a competition - they're both good use cases.

This is misleading. I’m not sure if you’ve read the article so it’s difficult to elaborate — it aims to explain precisely that.

There isn’t such a thing as “Bluesky getting federated” — that doesn’t on its own mean anything. In Mastodon world, “getting federated” means many copies of the same webapp emailing each other. In atproto, you don’t create many copies of the same app. Instead, it’s shaped like the web — individual users can host their data in different places, and apps aggregate over that data. There’s no point in having many copies of the same app.

The BGS server you’re referring to is the “relay” mentioned in the article. Running your own relay is possible (Blacksky does it, as mentioned in the article). It costs about $30/mo with the current traffic. However, note that a relay is very dumb (it’s just a retransmitter of signed JSON over websocket). It’s cool that anyone can run one but by itself this isn’t a vanity metric to chase. We’ll probably see more independent relays but usually someone would run one for a reason — to insulate a company or a community from upstream failures, or maybe to censor things (in repressive governments).

This is more nuanced in Rust's case.

Rust is trying to systemically improve safety and reliability of programs, so the degree to which it succeeds is Rust's problem.

OTOH we also have people interpreting it as if Rust was supposed to miraculously prevent all bugs, and they take any bug in any Rust program as a proof by contradiction that Rust doesn't work.

So you're telling me I shouldn't bother to take a split-second to glance down the street, but instead...

...grab my phone, unlock it, navigate to the app, wait for it to load, wait for it to figure out my location, wait for it to make an API call, try to figure out which of the two "34th and 7th" stops is the one going in the direction I want (since it's a two-way street with bus stops on both side of the intersection), click on one randomly, confirm from the first bus destination listed that I did click on the correct direction, otherwise go back and click on the other one, and then look at its ETA?

Sometimes it really is just better to use your eyes, to figure out that the bus is going to reach the bus stop in about 30 seconds, and that it'll take you 30 seconds of brisk walking to reach it in time, so you'd better start making a beeline now.

The same thing is happening in Greece. The new mandatory digital ID replaces and unifies everything about citizens in one place, "to make it easier for government services to share information between each other". It can indeed be useful, but the privacy implications are enormous. Just imagine that a policeman, employer or anybody else with access to the information linked to the ID can instantly view our medical records, tax status and even simpler things like if we've ever been caught driving while drunk. Nobody knows what other information could be attached to it, but it's certain that it can be used to discriminate against us.

The worst part is that we no longer have any power to do something about it. Eventually, after it goes through the testing phase in the UK and Greece (and a few other countries where it's being implemented), this will probably roll out on a global scale, making privacy impossibly. I'm starting to get this feeling that in the next decade, we'll be living in 1984...

> The way to protect against the lethal trifecta is to cut off one of the legs! If the system doesn't have all three of access to private data, exposure to untrusted instructions and an exfiltration mechanism then the attack doesn't work.

Don't you only need one leg, an exfiltration mechanism? Exposure to data IS exposure to untrusted instructions. Ie why can't you trick the user into storing malicious instructions in their private data?

But actually you can't remove exfiltration and keep exposure to untrusted instructions either; an attack could still corrupt your private data.

Seems like a secure system can't have any "legs." You need a limited set of vetted instructions.

One can explain features that are possible on ATProto but not Big Social without talking about "decentralization". My pitch to the non-technical typically follows or covers these points

- Social today is not healthy

- Single account instead of N

- All apps keep your data in your database

- User level choice over apps, algos, moderation. Esp algos, my social media usage patterns have changed for the better since I started using custom feeds

- Real competition in social media

- Take back our shared digital experience from a handful of billionaires deciding everything and keeping us locked into their attention economy

Digital ID is the pattern of the mark in revelation.

Once you let go of God (worship of truth and love) the government or other totalitarian force will try to control people top down. The logical way is to identify them.

You go from a system of free will and distributed cognition to one of enforcement top down. New things can always be added to it as you don't control it. All the "problems" of the states will tag along.

Making it digital is way worse than anything before because it allow to control you without having to pay a cost in enforcement, you control the flow of money, of exchange, you let the computer control people allowing a system so top down the Nazi and communist couldn't even imagine.

Worse part, it's already there for sure but in shadow form, they have all the info about the people, it's just not tied to financial transactions and out there in the public.

I've got a treat for you, cloudflare's business model moved heavily towards crime as a service during the last decades, including DDoS botnets that host their own CnCs behind cloudflare, while themselves even relaying cloudflare DNS data to DDoS cloudflare instances itself.

The guy behind Crimeflare, when it was still available, tried to accumulate a dataset by running his own resolver, which filtered out domains in the zones of cloudflare's known ASNs.

This was actually also part of a lawsuit against lieferando (takeaway) because they're registering domains of restaurant owners and blackmail them into using their delivery service, after they already registered the Google business entry with that cloudflare domain to a call center of Takeaway, so the actual owner of that restaurant has no chance in terms of SEO and google searches that people would find them again.

Anyways, the dataset is pretty fascinating:

> Moreover the bus are more dangerous for cyclists and pedestrians.

Avid cyclist myself, personally I'd rather see the stiff necked 80 year olds in cars as old as them (so barely any safety features) with tiny tiny mirrors gone off the road.

Bus drivers are at least regularly examined for their health, the buses themselves have a lot better maintenance done on them than the average private person, they got more mirrors than a disco ball, and at least here in Germany, the bus fleets are routinely updated to have allllll the bells and whistles. Lane keeps, dead-spot alerts, object tracking/warning and collision avoidance...

As for the noise: yes a bus is louder, but (IMHO, having lived on a busy road that was suddenly not so busy at all during Covid) I can handle the occasional bus every 5 minutes way better than the constant car noises.

This whole thread is a much bigger indictment of humanity than the neon app. A system that gives the poor (who are already far richer than under more or less any alternative system/any time in history!) an additional opportunity to make money off something that is otherwise worthless to them.

People who, of course, know much better than the poor what's good for them, condemn giving them that opportunity.

That's really just added work, IMO, and likely room for security misconfiguration between backend and proxy. You should still be validating and everything on the application server to inspect identity and possibly attributes like roles, so in the cases where you have invalid tokens you do the work once, just in the proxy instead of the backend, and with valid tokens you will do the signature validation work twice.

there's a difference between "the police can request this information from an individual" and "this information will be automatically gathered from everyone at all times and stored by the state". for one, there are circumstances in which the police are allowed to request that information and you can say "no", and there are also practical limits to the number of police that can be out requesting. The central equivalence you're trying to draw here is simply false.

The train of thought didn't die with Thoreau. It lived on in the minds of those such as Murray Rothbard, and to the extent as it applies to universal healthcare, also known fringe character (and nobel economist) Milton Friedman. Of course Locke himself (a major inspiration for the US constitution, which very narrowly constrains what the federal government can spend money on), I suppose too old as he's the oldest of all of them, only justified taxes so far as they allowed the government to enforce negative rights, that is rights for one person not to molest another rather than positive rights like an entitlement to get something from another such as care.

>your thought is that we have artificial scarcity on medical care because we don't license doctors we could

Really all the above. Probably even more so due to stuff like the intertwining of the insurance and pharmaceutical and medical industries with regulatory apparatus creating all the worst regulatory capture incentives to rent-seek patients with the free market destroyed.

All you said is very reasonable.

But then you look at image gen. The established one, namely Adobe, are surprisingly not winning the AI race.

Then you look at code gen. The established IDEs are doing even worse.

I don't rule out the possibility of music being truly special, but the idea of "established tools can just easily integrate AI right" isn't universally true.

there's no explanation for why certain actions or choices are made.

it doesn't make sense why phantomjs gets a score of 7 while chrome headless gets 8, or why phantomjs and selenium aren't considered headless browsers or automation tools. why the most common legitimate screen resolution is flagged as suspicious or why tools like curl or wget which download conten, are running javascript instead. they would be in a stack that checks ua server side, not in js

People are scared of all kinds of things. Is it good management to accept that as a reason to paralyze most of the world? (And no, spending all effort on pushing one hobby and stopping the rest doesn't help. It goes exactly in the direction of paralyzing the world. Like "SMR". It wouldn't even solve anything: sooner or later an SMR "NUCLEAR!!!" device will have an accident and then what?

Is that production? When you basket it into "low level" it sounds like a base case but it really isn't.

In production you don't have local storage, RAM being used for all kinds of other things, your CPU only available in small slices, network effects and many others.

Be careful with your reasoning. Remember that the current ruling party in America (as well as growing movement in Europe) is using the same rhetoric to go after liberals and trans people.

The problem isn't that any sensible person supports genocide, it is that insensible people can get to power and trick normal people into thinking genocide is necessary or not happening at all. They do the former by saying "if we don't commit genocide then they will commit genocide against us".

The problem is who gets to pick who is right and not? The problem is that if you limit the right to limit speech then good rulers won't abuse that power but evil ones will. It's because they are the ones who pick and choose. It's why you have to protect the rights of those you abhor. Because if you don't you build the powder keg of Turnkey Tyranny. Doesn't matter how many signs you put up, eventually someone will light a match. My accident or because they want to watch it burn.

So yes, to protect those groups being persecuted (trans, minorities, and Jews alike) you need to protect the speech of abhorrent groups like Nazis. You don't have to like it. And you don't have to, and shouldn't, protect the actions of Nazis, but you do have to protect the speech. It's exactly why the ACLU has done this in the past because every authoritarian loves to use abhorrent characters to justify overreaching laws.

We're on Hacker News for fuck's sake! How often have we seen the same play but replace "speech" with "encryption" and replace "Nazis" with "pedos and terrorists". It's the same stupid game!

Thank you Dan for the post! I think two other things to point out:

1. Because open social has to actually compete for a user's business, any sufficiently mature platform build in the ecosystem will necessarily trend towards being more responsive to those users needs, which will trend towards a better product than the legacy crop,

2. Precisely at a moment where governments lean on large, visible corporate entities to enact desired policies, splintering that ownership helps ensure a resilient communications network

Seems pretty simple unless you are secretly stanning for the orcs. Ownership of the land should revert to the status quo ante before Putin's initial incursion into Crimea. Those whose property has been destroyed or mined should be compensated with seized Russian assets. Kidnapped Ukrainian children should be returned to what's left of their families.

What alternatives would be more fair, from your perspective?

> I don't know whether the city is correct about its power to terminate the contract

They were unambiguously violating state law intended to prevent this exact scenario when they were sharing the data with the federal government. Some lawyer is going to be having a bad year and a black mark on their resume if they didn't have a statutory breach clause in the contract with a city government and even if such a clause doesn't exist there is an extremely strong case for it regardless.

They have self-inflicted a business disaster upon themselves for doing that in a state like Illinois. In the event this holds up under that legal theory every municipality in the state has a case to dump them, to say nothing of getting new contracts there and in any place that has the same values.

Author here,

my motiviation was intellectual curiosity and some random Lichess reading about chess engine authors wondering whether 8 bit e.g. numbers 0 to 255 (or 1 to 256), will be enough for storing the number of legal moves. Which triggered my brain: "I HAVE THE KNOWLEDGE TO SOLVET HIS FOR HUMANITY :O". It's not at all relevant practically, as you have elaborated, and there probably is a more elegant proof that 256 can't be exceeded.

My view is it's always organised elites making the decisions, no matter the system. Nominally left-wing parties often make brazen right-wing moves, and vice-versa. The votes that matter are those of the MPs, Congress members etc. which are always influenced by a range of factors and organised factions. That's the actual decision-making mechanism.

Cheers on the study!

Let me first describe what I meant by fringe though. Take a random adult going to the hospital, not elderly, with no other major health conditions. When he walks in the door, what are the distributions of issues that he might end up having? Sepsis is going to have a probability of near 0. By contrast the typical patient that might present with sepsis - elderly, other major health conditions, well into senescence - he is generally indeed 'knocking on deaths door.' He might not answer this time (though there's a decent chance he will!), but he will imminently.

Your study compared hospitals based on a number of factors. The most significant was high volume, but in that case the difference between the highest volume hospitals and lowest was a 13.3% rate of readmission vs a 11.2% rate of readmission for hip replacement, and 12.4% vs 11% for knee replacement. Again I think this is another example of when you look at the actual data, outcomes fall quite close.

Beware their method of taking a sampling and breaking it into buckets and comparing those buckets. If even hospitals/patients were identical (which I'm certainly not claiming) and so the results were literally just random noise on a distribution, you'd see a major difference between the top and bottom buckets due to the nature of random distributions - 68-95-99.7 and all that. Their results show a signal beyond that, but it's generally a very misleading way of presenting data because of this issue.

Pre-pandemic hispanics had a life expectancy of about 82, which I described as comparable to the 85 of billionaires. I'd certainly expect billionaires to be higher for the endless reasons outlined in the already linked Hispanic paradox. The fact that it's only 3 years, less than 4% longer, is the point.

All the contract stuff is too muddled to even consider debating online.

I'd start with one HUGE obvious waste. Why don't the buses anywhere have some sort of uber style pickup. My point. I see countless buses running empty all the time through the day where I live outside of busy hours. It is so depressing to watch 3 empty busses pull up to an empty stop to not pick anyone up then do it again and again and again.. I was once told it cost something like $250+ every time an empty bus drives one direction on its empty route. And there are hundreds of busses that do this for hours each day. Just so in case someone is there they can be picked up.

It seems like a dynamic system for determining where where people that need the bus are would be a massive saving. Or really just changing to a taxi style system only using buses during rush hours. I think some cities are actually experimenting with this.

Someone is gonna come at me about the reliability scheduling of transport for underprividged. But they have never actually rode a bus route so they don't know that the buses are as reliably late as they are on time in 90% of cities. This change would likely improve scheduling for people that need it.
