This is the second blog post about the sched_ext, a BPF-based extensible scheduler class. In this blog post, I briefly update what has been happening in sched_ext, then introduce the scheduler architecture and the sched_ext API. After reading this, you should have a good understanding of the sched_ext architecture and be ready to read the source code of any sched_ext schedulers.

As a professional industry, Hollywood is probably the worst offender when it comes to being so obsessed with itself that it genuinely can’t tell when it’s doing something in service of pandering to and perpetuating its own weird culture.

I kind of look at this in the same way as the fact that so many movies or TV shows can’t help but eventually have a plot where someone makes a movie or a TV show, maybe at a stretch a stage production. And, somehow, all the characters know a whole lot about stage productions.
> This will go nowhere

As will this comment thread. We saw the same rhetoric on Holmes and Bankman-Fried. Once they were charged it was obvious they’d get off. Once convicted that they’d get a light sentence. Once sentenced that they’d have their sentences shortened, et cetera.

It’s a lazy learned helplessness that’s always potentially right because it feeds into a type of cynicism that has always been part of human nature in every culture since the beginning of history.
D'oh! Thanks for the heads up.
NYC OMNY allows for direct payment from a debit/credit card via NFC at the turnstile. this has privacy issues but i think they're ameliorated if you use a smartphone.

i think you can buy a transit payment card if you need one.

no paper tickets. cool ephemera but pretty wasteful.

would be pretty cool if/when we see a day where provably private cryptocurrency microtransactions allow for both real privacy and the 7 day fare cap feature.
Some Boeing test pilot was boasting about using "Jedi mind tricks" to mislead the FAA. He was one of people responsible for convincing the FAA to drop mandatory training requirements linked to the MCAS system.

This is interesting but clearly not intended for security/cryptographic applications... no security hardening, no hardware cryptography, and it's also not available in a card form factor according to the datasheet.

This works for some things, but not for everything

If it was your job to tighten the bolts and you didn't, that's one easy slam dunk coming your way. And they're right.

Any engineer with AoA failure information (which I assume in Boeing is an easily obtainable information) should have designed/reviewed/approved MCAS in a different way.

And who will win? Those "smart people"(I hate this word, being nefarious is not smart, and stop gaslighting us by humanizing an evil multi trillion corporation doing illegal things, as "people") creating their own market monopoly, or the regulatory bodies of large governments that can regulate those monopolies in their regions?

History tells us that the institutions with laws, guns, judges and a monopoly on violence rules over "smart people" who just make phones.

Apple's only retaliation is making life shit for EU users or pulling out of the EU market which they won't because that would leave a China style vacuum that Google or a local EU competitor will take after a period of painfull transition for the EU consumers.

The EU consumers can live without iPhones. Can Apple's shareholders live without Eu's profits?
I was in Rotterdam recently. Their metro system uses multiple approaches, some kind of RFID for hard tickets, NFC payment (without a ticket at all) and QR codes for time-limited tickets that you can buy in a phone app.

Getting those QR code readers to read the QR code was a nightmare. Almost all the cameras have heavily scratched protective windows in front of them, which makes the reading process a struggle of trying to find a working angle. Of course the scratching is vandalism, but subway systems must be robust against vandalism, cause it's something that happens and must be expected.

I switched to per-transit payment via NFC after using one of the time-limited tickets and realizing that you need to consider yourself lucky if you find just one working QR code reader at most stations. NFC worked like a breeze.
See comment below.

More generally what I'm seeking is something in the card form factor which is suitable to store cryptographic secrets (i.e., a smartcard).

Separate IC is a disadvantage here since it creates a vulnerable security boundary and makes it infeasible to integrate the chip into a thin card.

Controversial opinon: linguistic evolution is slowing down considerably.

1. Ever wondered why English spelling is so stupid? It's because it's based on an older version of language, but we never decided to update the spelling, so we just roll with it. How is that supposed to change in the future if it hasn't changed so far?

2. At first, text used to be a representation of spoken language. Nowadays communication is mostly via text, so it's more like "speech is acoustic representation of written language" and written language, as per example of Modern English, is not likely to naturally evolve once it's rules have been set, at least not as likely as spoken language, which can strongly vary from generation to generation.

3. Smaller languages, which potentially could be a source of new words and grammar, are quickly dying out due to popularity of English. Icelandic didn't evolve much through last thousand of years because its speakers had little contact with speakers of other languages. English will do the same by simply eliminating other languages.

I don't think we're there yet, but at some point in the future English will reach its "final form" and from there on, only minor changes here and there will happen. Just like the entire world has almost collectively decided to use arabic numerals, or the metric system, and we don't expect any revolutionary changes there anymore.
> Expropriate the company, at least 51%, take control and let public officials (knowing the US way, it will be some army general) set up checks and controls where necessary

Why? Just criminally charge and fine them into bankruptcy. This wipes out shareholders and lets the creditors—the government would be a big one, on account of the fine—reorganise the company and review all the books and records in a legally precedents venue.

Everyone keeps trying to invent new mechanisms for what fines and bankruptcy already do.

> It's just late-stage capitalism at work.

>> Not really, it's just bad management

I believe the argument being made is that in "early-stage" capitalism a company could not afford that type of management, as it would immediately loose the market due to "true" competition and other "quality" options being available.
You'd probably be the only person using an IDE for development in Picolisp.

The main author does (or at least did) a lot of development on a tablet, with his own software keyboard (https://play.google.com/store/apps/details?id=de.software_la... , which I've enjoyed for years on my handhelds, in part due to the tmux-arpeggio), and his own editor (https://picolisp.com/wiki/?vip ). I think most of us do something similar, using vim or vip, maybe on larger computers, but generally a pretty minimal setup.

The REPL has string based completion, besides completing symbols it will also complete file paths. Development is heavily REPL based, you'd spend a lot more time inspecting the runtime than searching for string occurrences in files.

From the REPL you'd also read the language reference, most likely in w3m, the preferred text web browser in this community. (doc 'macro) will open the reference on this entry if you started the REPL with 'pil +', where the + is a flag denoting debug mode. You can expect the web GUI framework to work rather well in w3m.

>asserts nothing will happen while citing a case where execs went to jail as proof. It seems logically inconsistent.

The gp wasn't being logically inconsistent if you see the rhetorical structure of his comment: anticipate and pre-emptively state the counterpoint and then counter that counterpoint.

- predict other side's possible counterpoint : "But Ebay execs went to jail"

- counter that counterpoint : "Yes but Ebay is smaller company that's not deeply interconnected with the government"

- gp's conclusion: Ebay situation is different enough that it is not proof that Boeing execs will go to jail

Readers' can have 2 different interpretations:

- I disagree with gp that Ebay and Boeing are different situations --> therefore gp is logically inconsistent

- I agree with gp that Ebay and Boeing are different --> gp is logically coherent

>OP is the one who brought that up in the first place, but they are using it to show it won’t happen. Which makes no sense.

Because the OP's reasoning is Boeing's "deep ties to the government" -- is what keeps it from happening.

I don't agree with OP. I'm just explaining what he wrote.

The readers' different reactions to OP's comment basically depends on how whether one buy's into the idea that the government's dependency on Boeing (military, space launches, etc) gives it an unstated immunity. The judgement of "logic" to his argument hinges on that.
Well that sounds like complete nonsense. As an Apple user id definitely take advantage of cheaper ways to purchase the exact same product.

Furthermore - No one is forcing anyone to click the "get this cheaper here" link ... But I'd bet you'd be surprised how many Apple users would click it if it was there. The user and developer both win in that situation.
That should be an informed decision. If users are happy to pay extra to Apple for convenience of use, then they should be aware of what is happening.

If 95%, like you say, are happy to pay extra, then it should be no problem for Apple to allow developers to communicate the Apple fees.

Spotify sells content distribution. Apple sells the permission to have your own content, that you distribute, run on devices that your users own.

As a EU-citizen, I'm not happy with this legislation and enforcement. I choose Apple versus Android, because I want the safe and user friendly ecosystem Apple offers. Otherwise, it makes much more sense to go with Android. Those phones are much cheaper and are very much the same quality-wise (performance, screen, form factor...).

The same goes with iOS on iPad. I'm very happy that my parents can use those devices versus a Windows machine (or even a MacBook) and know that they are pretty much safe from malware.

Even now, I noticed that with the mandatory browser selection screen both my parents independently have moved on from built-in Safari to Chrome (independently), since that was the only browser name they know. And now they are in a much worse position privacy-wise than before. Which is certainly not in the spirit of the GDPR and DMA.

Macos is less than 1% of the PC gaming market. The decision to port to macos at all is questionable, spending extra effort to really "feel" like a mac native app would be crazy.

Your experience is bad because you are not the target market.
> g05t5

What does that mean?
Your opinion of what users supposedly want is irrelevant. What matters is that the law mandates these options and Apple refuses to comply.

And no - I prefer iOS, for various reasons (such as smooth integration with macOS, better UI), and wanting to download apps from the Apple app store is not the reason.
Just curious. What are you guys using in place of centos? This days, ny servers are all debian or ubuntu server based.
How does other users' ability to install stuff outside of Apple's control impact your enjoyment of your devices?
Not the comment you're replying to, but I also have a couple of internal winforms projects at work. They make it much easier to diagnose and debug issues with a backend service that works with GIS data, using libraries like GMap.NET. Come to think of it, the company's environment management tool is a Winforms application that gets used in every production instance. For basic UI tooling in a dotnet shop it's second to none.
Any examples and good tutorials on how to best go about it?
TrueType fonts have had a Turing complete virtual machine (almost?) since the beginning. It is used for "hinting" to allow partially colored pixels at low resolutions to remain legible. It's basically a program that decides whether to color a pixel or not to allow fine tuning of low resolution rasterization.

This isn't used as much today with modern large resolutions where we can get decent image quality from just rasterizing the font outline with anti aliasing.

This example, however, is using wasm embedded to ttf fonts which is not the same as ttf hinting byte code.

Have they ever specified any reason why they prevent users from finding this out? I read somewhere (I think Epic v Apple) where the judge surmised that App store model was not just payments but the whole mechanism of tracking subscriptions, cancel and refunds, and standard pricing for purchases. I can understand the viewpoint that Apple customers might expect the same functionality if they purchase directly on site. But then, let the developer explain that too. "You can get this cheaper on website, but will no longer be able to cancel via App Store" is a fair enough line that can be mandated just like they mandated everything else. Think they will have to do away with it eventually, though from the outside it looks like they think if they drag their feet on this, maybe regulators won't come for other things.
Do you think that issues being discovered in 2018 with 2 planes and 346 people lost and systemic safety issues persisting since then qualifies as "relatively quickly"?

My comment isn't coming out of thin air. I'm trying my best to look at the big picture. What I see is that the military industrial complex is bigger than anyone (including myself), can comprehend. They are an immovable force. If they go down, so does our country. It's that simple. This isn't eBay or some couple billion dollar fraud, we are talking about. It's much much bigger. This is trillions bigger.
Considering the glut of scammy, ad-filled garbage on the official App Store, I'm not convinced we haven't ended up exactly where you claim we haven't. That being said, I do agree with you that the vast majority of users probably don't care about alternative app marketplaces (but for the small majority of us who do, I'll continue to champion the EU's efforts here).

Also, for the love of god open up the Apple Messages API please...
I recently visited Paris. I read up and watched videos on how to use the metro. They didn't really cover many of the important local customs: I let people off the train before trying to cram in and I held the exit gates open on my way out of a station so they didn't slam in the next person's face. I must have stuck out as a tourist. The "act like a local" public info available is never sufficient.
You're upset that your parents were free to make some choice that you feel is wrong, and you believe Apple should be allowed to take that choice away from them?

Honestly, I feel that Apple has completely brainwashed some people. Comments like yours abound, complaining about the dangers and disadvantages of freedom and choice. You're only a few words away from "freedom is slavery".

Ask HN: Supabase vs. Neon Database: Which One Should I Choose?
I wonder if HN could share their favorite serverless Postgres database?

I'm currently evaluating different database solutions for a SaaS I'm working on, and I've narrowed it down to Supabase and Neon Database. I've done some initial research, but I'm looking for more insights from the community.

Here are a few specifics about my project:

* Scale: Anticipating moderate to high traffic
* Tech Stack: very minimal I can go for a web app:- JavaScript, TypeScript using NextJS, ReactJS- TailwindCSS, RadixUI for UI- Deploy on Vercel
* Key Requirements: Real-time capabilities, ease of use, performance, cost-efficiency, and good support/docs.

Questions:

1. Performance and Scalability: How do these two compare in terms of handling large-scale applications? Any real-world experiences would be great.
2. Ease of Use: Which one has a more developer-friendly interface and better docs?
3. Real-time Features: How do their real-time features stack up against each other?
4. Community and Support: How active and helpful are their communities and support teams?
5. Cost: Any insights on the cost-effectiveness of each, especially for scaling applications?

I'm leaning towards one but would love to hear your thoughts and experiences.
Some people have all the luck!

Another library/documentation that commits the sin of not showing any examples
The market can't do much in this case, as within the US, Boeing has a monopoly, and internationally its only competitor is Airbus. And there is a very strong "lock-in" in regards to pilot type rating.

So while there is some competition, the airline industry is very much controlled and regulated by government.

And here in particular there was a lot of failures in particular with the FAA allowing Boeing to self-regulate (when has that ever worked?) and then the DOJ failing to prosecute after the two deadly crashes.

It really seems like a systematic problem, not an exception to an otherwise healthy situation. Time and time again we see a lack of consequences to corporate greed when those actions are literally killing people.

You're quite correct that things are not as bad as during the robber barons era, but that is a pretty low bar. We can do much better.
