PRI is TDM. It isn't packet-switched; there are no packets on the voice-carrying B channels. It uses timeslots, instead.

> NB, "always 23" ... unless you're in Europe, in which case 23 === 30.

I believe I was very specific about the locality I was referring to, but I am appreciative of the seemingly-disingenuous pedantry that is apparently unfettered by such arcane concepts as "context".

Do you happen to know how Ferrocene relates to AdaCore's Rust compiler?

https://www.adacore.com/press/adacore-announces-the-first-qu...

> ISO 26262 (ASIL D)

Isn't that only for a very small subset of Rust and its standard library?

Also, do you happen to be able to explain this comment?

https://reddit.com/r/rust/comments/1nhk30y/ferrous_systems_j...

> I think it's important to note, the certification is only for a subset of the run-time, which means some language features will not be available. Also, the certification is only to SIL-2 level, so any projects requiring SIL-3 or 4 will still not be able to use the Ferrocine compiler!

I view touch screens, keyboards and mice as the saddle points in the usability landscape. These kinds of decides don't change much because their designs have converged to an efficient form factor, from a usability perspective. That does not mean there is nothing better, perhaps these devices sit in a false saddle point, and perhaps there is something better that has not been invented yet.

So what's at loggerheads here is:

* The LLM has strong and deep rooted belief in its knowledge (that a seahorse emoji exist).

* It attempts to express that concept using language (including emojis) but the language is so poor and inaccurate at expressing the concept that as it speaks it keeps attempting to repair.

* It is trained to speak until it has achieved some threshold at correctly expressing itself so it just keeps babbling until the max token threshold triggers.

At first you think what an incompetent government would do such things, but even OVH pretty much did the same a few years ago. Destroyed some companies in the progress. A wooden floor in a datacenter with backups in the same building …

Fonts can be complicated. Using nonsense like [1] (specifically contextual alternates), you could have the glyph for the first letter of a word depend on the last letter. I don't think you could get that to work for all letters in an arbitrary length word, but making a font that works for all words shorter than say 20 characters should be doable.

You can actually do this in C as well. The Windows API has all sorts of handle types that were originally all one type: HANDLE; but by wrapping a HANDLE in various one-member structs were able to derive different handle types that couldn't be intermixed with each other in a type-safe way without some casting jiggery-pokery.

It's just much, much easier and more ergonomic in Ada.

Nobody is actively building out nuclear power. Microsoft is turning on a recently decommissioned facility.

New nuclear is too expensive to make sense. At most there are small investments in flash-in-the-pan startups that are failing to deliver plans for small modular reactors.

The real build out that will happen is solar/wind with tons of batteries, which is so commonplace that it doesn't even make the news. Those can be ordered basically off the shelf, are cheap, and can be deployed within a year. New nuclear is a 10-15 year project, at best, with massive financial risk and construction risk. Nobody wants to take those bets, or can really afford to, honestly.

The default background colors on early browsers wasn't always white. On Netscape Navigator on the Mac up to about version 4 the default background color was #C0C0C0 (IIRC). I seem to recall that also being Mosaic's default background color. Navigator on Windows had white as the default background color as did IE.

My first excursions on the web were on Macs so I thought something pages were doing some Windows-specific trickery when I first saw the same pages on Windows with white instead of grey backgrounds.

Even a lot of books on HTML in the early days had screenshots from Macs and you'd follow an example on Windows and the output would look different because of the different default background color.

I think you need to make some better arguments to convince. Your argument only makes sense when wholesale cost of solar panels is significantly cheaper than retail. The better the economics of scale (i.e the smaller the difference between wholesale and retail) the more favourable "DYI" becomes, because the person had home does not need to cover the overheads that are necessary for large scale installations (financing, management, transmission, planning...). It's the same reason that hiring a vps to run all your compute is not necessarily cheaper than buying your own pc.

When you said it depends on context, I thought you’d give a positive context. Using as a means to try and restore broken trust doesn’t sound very positive. Plus, if the dishonest one knows the cell phone is being tracked, they can work around that.

I was thinking of a one person realizing they need some milk, so they see their spouse is at the grocery store already, or on their way home with one on the way. They can make that timely call if it makes sense, and if it doesn’t make sense based on the location, they can add it to the shopping list.

My sister shares her location with me and I will use it to know if it’s a good time to call. On Sunday she goes to church, but I don’t know when. I can check the location and see if she’s in a church or somewhere else, so I’m not calling when she can’t answer. I do the same thing with my dad, I will generally only call if I see he is at home, so I’m not interrupting an event he might be at.

> It is also why Apple refuses to bundle chargers and cables (or at least, it tried to do so, until EU forced it to bundle them; but Apple does such cheapskate shenanigans in the other continents, where pro-consumer watchdogs/laws are lax)

You got this backwards, the EU is who has been pushing for the un-bundling of chargers. That was the whole reason for their push towards universal USB/USB-C adoption - so you could buy a new phone and keep using your old cable and charger, for environmental reasons.

This is also quite explicit in the EU law - it literally requires sellers to offer buying a device without the charger if you don't need one

> Directive (EU) 2022/2380, Article 3a

> Where an economic operator offers to consumers and other end-users the possibility to acquire the radio equipment referred to in Article 3(4) together with a charging device, the economic operator shall also offer the consumers and other end-users the possibility of acquiring that radio equipment without any charging device.

The only country that requires Apple to bundle a charger is Brazil.

Oh lovely - need to put Ada on the learning plan. Formal languages were a bit of a drag because you needed to maintain a separate "specification" copy of your critical code.

Going through Ada sample programs and surprised I can grok stuff without knowing anything about the language. Wondering why it never took off in the standard software world. Sure its a bit verbose, but so are Java and MacOS API's
Show HN: NanoBibi – AI Creation Platform for Images, Videos, and Audio

Hi HN!

I built NanoBibi.com, a free AI creation platform that lets anyone generate AI images, videos, and audio in one place.

The platform uses models like Google Nano Banana (Gemini 2.5 Flash Image) and ByteDance Seedance-1-Pro to create cinematic, high-quality content directly in your browser — no installs or accounts required.

If I turn on v6, it should be exactly the same aside from the packet format. I still have 1.2.3.4/32, there's still NAT, bans/rep preserved, same routes. That would be such an easy decision, nobody would hesitate.

Meanwhile, DNS and such would need to be upgraded to support 128bit addrs, but they'd still work with the old ones too, so again easy decision. Then once it's safe, any ISP short on addresses can start handing out /64s.

I know there are also v4 to v6 maps, but that's not default and is forever limited to 32-bit.

Let's run the numbers:

LTO-9 ~$92/tape in bulk. A 4 drive library with 80 drive capacity costs ~$40k* and can sustain about 1 Gbps. It also needs someone to barcode, inventory, and swap tapes once a week and an off-site vaulting provider like Iron Mountain. That's another $100k/year. Also, that tape library will need to be replaced every 4-7 years, so say 6 years. And those tapes wear out over X uses and sometimes go bad too. It might also require buying a server and/or backup/DR software too. Furthermore, a fire-rated data safe is recommended for about 1-2 weeks' worth of backups and spare media. Budget at least $200k/year for off-site tape backups for a minimal operation. (Let me tell you about the pains of self-destructing SSL2020 AIT-2 Sony drives.)

If backups for other critical services and this were combined, it would probably be cheaper to scale this kind of service rather reinventing the wheel for just one use-case in one department. That would allow for possibly multiple types of optimizations like network-based backups to nearline storage to then be streamed more directly to tape and using many more tape drives, possibly a tape silo robot(s) and perhaps split into 2-3 backup locations obviating the need for off-site vaulting.

Furthermore, it might be simpler, although more expensive, to operate another hot-/warm-site for backups and temporary business continuity restoration using a pile of HDDs and a network connection that's probably faster than that tape library. (Use backups, not replication because replication of errors to other sites is fail.)

Or the easiest option is to use one or more cloud vendors for even more $$$ (build vs. buy tradeoff).

* Traditionally (~20 years ago), enterprise "retail" prices of gear was sold at around 100% markup allowing for up to around 50% discount when negotiated in large orders. Enterprise gear also had a lifecycle of around 4.5 years while it still might technically work, there wouldn't be vendor support or replacements for them, and so enterprise customers are locked into perpetual planned obsolescence consumption cycles.

So by bringing up shading and suboptimal angle you're already admitting that for an unshaded balcony these things make sense? The overhead of hanging one of these over the rail of your balcony is pretty minimal, compared to industrial scale installations. There is plenty of overhead with finance, management, billing, land use, and utility profits. That's why it makes sense.

This project made me learn about and attempt to implement the SPAKE2 protocol and HKDF as an exercise. It's quite fascinating. It lets you upgrade a short password to a long key, but requires trusting a server to rate limit attempts on brute-forcing that short password. It seems difficult to find a practical use case for it tho. Because it's only relevant when it is impractical to send a long key. But if you think for a second, lets say you are transferring from a desktop to a phone, you can show a QR code and scan in with your phones camera, thus achieving a secure handshake bypassing the need for SPAKE2 all together. Maybe it would defeat the simplicity of the tool, but if it also provided a long string of words for the key, a user could optionally send all the words instead of just the first few and get themselves a secure key without needing to trust the server.

I'm mixed on touch screen vs physical controls happening. A Tesla has physical controls for shifting, turning, cruise control, current media and I guess you can include accelerate and brake. That said, I want all cars to be the same. I want them to have Android Audio, Apple CarPlay. I do not want custom apps in each car. I just want to connect my phone in and have it do all the things unrelated to operating the car itself.

So at least in some ways, I want them more the same, not less. I live in an area where Waymo is common so I see self driving cars all the time. In other words, unlike people not in an area like this, I have actual experience with them working and working well. As soon as they are available for purchase I will buy one. Ideally one with no controls. No steering wheel, no accelerator, no brake peddle, no turn signal. At which point, I suspect, like phones, they may get even more alike. All that stuff is un-needed in a level 5 self-driving car

I'm sure someone is going to respond such stuff will be needed for emergencies or whatever. I think that middle stage will only last 5-10 years and then they'll take out the manual controls. They took out manual controls from elevators 70 years ago. They're taking out almost all controls now. IIRC Toyota already has such vehicles. I know Honda showed of designs years ago. They're a platform that carries a box. The box can be a cargo box, a food truck box, a 12 person passenger box, more comfy 6 person box. No driver's seat.

Yeah, but that's not the point I was trying to make. My main point was that traditional thinking is that schools need to fight AI or students won't learn. But I think we'd be better off working with AI instead, customizing education according to each student's interests and needs, providing immediate feedback, etc. And I expect school buildings themselves will still be used, if that wasn't clear. I'm not pitching a "school from home" campaign, not after 2020 forced one on us.

Of course teachers still have a role in maintaining discipline, motivation, and things that computers can't do, as well as validating that the AI systems are behaving correctly for the things they can.

The biggest thing I don't like about that approach is it's yet another bump in screen time, which, eh, if I think hard enough on that aspect, it maybe makes me hate the whole idea, so.

You'll also notice the same thing happens for other non-existent emojis that sound like they should exist: dragonflies, lemurs, possums, blackberries - even Claude 4.5 will start off by saying "Yes!" and then correcting itself. It will immediately give the right answer for very specific things that you wouldn't expect to get their own emojis though.

I realized if someone were to assign me the ticket for fixing this behavior, I would have no idea where to begin with solving it even with this blog post explaining the problem, so I'm very curious to know what the most practical solution is. (They obviously aren't adding "If someone asks you about a seahorse emoji, there isn't one available yet, no matter how strongly you believe one exists." to the system prompt.)

"I have no idea who you are talking about leave me alone you freak."

if data is linked to me via some vague data that is based on similarities there's no world where that can be used as a trustworthy source or at least not putting doubt into the person who is using such data as often times it also links to a bunch of incorrectly assigned data. It's like trusting LLM's with everything they say.

You've said "I want to create a global variable and absolutely none of the described ways in the docs or stackoverflow work for my example" a few times now, and I still have no idea what you are stuck on. Global variables are much the same in C and Rust, as ownership problems largely disappear for global variables.

Maybe if you provided the example, someone might provide an insight. I hate to suggest this - but have you asked an AI? They've seen a lot of code. If you give an AI enough context it will likely cough up examples of how others have solved it.

>The Schneider Electric report estimates that all generative AI queries consume 15 TWh in 2025 and will use 347 TWh by 2030; that leaves 332 TWh of energy—and compute power—that will need to come online to support AI growth. T

+332TW is like... +1% of US power consumption, or +8% of US electricity. If AI bubble burst ~2030... that's functionally what US will be left with (assuming new power infra actually built) mid/long term since compute depreciates 1-5 years. For reference dotcom burst left US was a fuckload of fiber layouts that lasts 30/40/50+ years. Still using capex from railroad bubble 100 years ago. I feel like people are failing to grasp how big of a F US will eat if AI bursts relative to past bubbles. I mean it's better than tulip mania, but obsolete AI chips also closer to tulips than fiber or rail in terms of stranded depreciated assets.

If the "outcompeting" is possible because of Chinese government subsidies, then it's important to protect local industry from unfair competition.

It's similar to the logic behind anti-trust actions against monopolists. If the playing field isn't level, then the USA government steps in to level it.

(Whether BYD is subsidised or not is another question, but the above is the logic of protecting local industry.)

No. It says that "most systems" in this data center are backed up to separate hardware on a different floor, and then a backup is made at a physically remote location. This particular G-Drive system was not on the standard backup process - it sounds like it was much higher volume than any others, so maybe they couldn't use it. They did have a pilot going to get G-Drive backed up...it was supposed to be scaled up to the whole thing in December.

I think you're misunderstanding plantain's point.

Where I live, in Argentina, every house has a water tank on the roof, which is filled from the water main through a float valve, like a toilet tank. Many houses need a pump to drive the water up to the water tank because the water main has such low pressure. This is somewhat expensive, and the pumps, float valves, and water tanks fail sometimes, which is inconvenient. And the tank is not really that high up, so the water pressure at the faucet is not that high, and it's somewhat variable, which is inconvenient when it changes the temperature of the shower.

Some other places I've lived, such as various places in the US, instead have a large shared water tank for an entire neighborhood, town, or even city—a so-called "water tower". If you've been to the US, you may have seen these. Making this work involves several expenses:

- Larger-diameter water mains to reduce head loss when water demand is high.

- Highly responsive repair crews to respond rapidly to water main breaks, because the higher-pressure water with a high flow capacity can be very destructive.

- The construction and maintenance of the large water tower, which is very dangerous if done badly.

- A high-powered pump to get water up the water tower in the first place.

However, these expenses turn out to be significantly smaller per person than the expenses of small per-house water tanks and water pumps. And they provide better service. (Also, because people are stupid, in the US they build many of their houses out of wood, so they need fire hydrants, which require the larger water mains anyway.)

So, the fact that people in my neighborhood Argentina are spending more to get worse water service is a failure of coordination.

Of course, people in the US can still put water tanks in their houses if they want to. In earthquake areas, it's even recommended to have a store of potable water that isn't dependent on the water main. But, because they have succeeded in collectively building excellent municipal water systems, they generally don't need to.

The claim that plantain is making is that people actually choosing balcony solar panels is a symptom of a similar failure of coordination. To me that seems plausible but not necessarily correct, for reasons I've explained in https://news.ycombinator.com/item?id=45487051.

Yes, the current American immigration laws are dysfunctional and thus unjust - they do not offer a clear path to citizenship for folks who have been here for multiple decades, who are productive members of society, who have obeyed (non immigration) laws and paid tax to the American government.

Sure, you can kick out the criminals and gang-bangers - no issues there. But kicking out restaurant owners and other tax-payers is ridiculous.

Also, unilaterally revoking Temporary Protected Status for folks is also a bridge too far. Those were originally issued by Obama for very valid reasons - the catastrophic 2010 earthquake and later humanitarian crises.

Sure, you can argue that Americans elected Trump and so he can do whatever he wants, but the cruelty has gone off the deep end now. The power given by his electoral win has not been applied judiciously.

From a constitutional point of view, I also see this App as simply representative of the right given by the First Amendment. If you block this app, one has set an extremely dangerous precedent.

But precisely because "financially successful" isn't a precise term, the concept can be and is manipulated by smooth operators. It's always possible to construct a plausible argument that true success lies just beyond what you could reasonably expect to make through your own efforts (and therefore you might as well throw your money at me for a chance to achieve it). I don't think we can separate Gen Z's incredibly high standards for financial success from the amount that they're marinading in ads for gambling, crypto, and scam investments.
