I do not think any real systems can ever achieve theoretically perfect Solomonoff Induction- only that increasingly good AI systems can be thought of as increasingly good approximations of this process. I do not know if any particular modeling approach has a fundamental dead end that limits its potential or not. However, my main point is that people claiming that they are certain of a particular fundamental limitation are mistaken. Current LLMs aren’t very intelligent, yet can already do specific things that people like Noam Chomsky have argued are fundamentally theoretically impossible for them to ever do.
I'd say Haskell is even simpler than Rust: the syntactic sugar of monads/do-notation makes writing parsers easy. The same sugar transfers to most other problem domains.
> Desktop is a typical place where you absolutely don't need realtime.

On a desktop, you want at least soft real-time when playing any sort of multimedia (audio, video, or interactive applications like video games). Otherwise, you get things like glitched audio or dropped frames.

I feel like "boring" is praise for an OS, not a criticism.

I have no problem playing most of my steam game library on my m1 mini, I can only imagine the M4 is even better. Of the games that won't run on macos, yeah, most are "triple AAA" shooters that I spend less time with lately, so all good.

The Beelink ser8 looks cool. If I build another PC, that will be high up in the consideration list. My current PC is a watercooled monstrosity that is about as portable as a bank vault.
Desktop use at its lowest latency is typically 17ms and up to 33ms when using a 60Hz screen with one frame in the buffer and whether you have to wait for the one after that. But most operating systems and games default to more than one buffered frame. Still, even that lowest case scenario is a pretty big budget of time. The microsecond precision of a RTOS is not necessary then. If you want to increase responsiveness or reduce latency for interactive use of desktops or phones there are different avenues to approach to shave off milliseconds at a time.

> What areas has the US annexed in the last 100 years?

Why stop at 100 years? Is it because the whole current USA territory is actually annexed?

FYI, here's the list of wars the US was involved into, most of them they started. I leave it as an exercise for you to count the casualties and add it up.

How do you degas a skull in a living mammal and have an unharmed animal after?
Usability. And/or good taste.
I start by asking what games they play, then together we look at ways to manipulate the game using code snippets, manipulating delay lag on the network to game the networking code using tc on their router if it is running Linux under the hood. Most importantly I make sure they understand the concepts they are manipulating so they can extend the capabilities to other games. It has to be something fun to keep their interest otherwise they will just move on to other things. I also show them some simple techniques to defend their router and PC against simple flood attacks most commonly needed in GTA4 and indie games such as blocking off inbound ports that the game opens on the router but are not really needed and dropping packets based on size, rate and combination of specific ports. They have to learn how to profile traffic and spot anomalies in wireshark correlated with the time their game or PC crashes. Nothing too advanced, just a starting point. If it's too advanced they will be overwhelmed and lose interest.

For clarification when I say kids I mean teens. The younger kids will learn from the older kids in Discord. The teens will taunt each other to get them to attack their machine. That too becomes a learning exercise that they will perceive as a game. Red team vs Blue, Yellow and Orange teams [1] Oh and yes I of course tell them which techniques break which laws and what will get them hired. There is some overlap.

I did the same, but did it on Debian Testing. Big mistake. KDE is not well supported on Debian. I too have seen the light in the Void and migrated about a month ago; better experience all around, including a modern KDE.
Beryllium is a good plasma facing material (low Z, low retention, low activation) and acts as a neutron multiplier, but it's highly toxic: only a few months ago ITER announced they scrapped the design of the first wall because working with beryllium was causing too many complications and slowing the project even more.

It's also so rare to be completely unsuitable for a power plant: a single DEMO-like reactor with a ceramic blanket (HCCB design) would require 70% of the world beryllium output to build and then burn through 200kg/year. Essentially you could only build a couple of these.
I disagree. I'd like to see Windows reduce in market share, but still remain a strong competitor to macOS and Linux.

There's a lot of cross pollination of ideas that comes from OS diversity and a greater resilience to cybersecurity threats, as it is unlikely for any one vulnerability to affect 3 different operating systems at the same time.
A single 0 just throws me off because it makes me think of octal.
Yes!

BemiDB natively supports two storage layers, a local disk and S3 (we assumed that most people would choose this in production environments to simplify management).

When I query Iceberg tables stored on SSD, it works superfast.
Yep. Again, I'm not looking for a perfect global solution.

Just some domain specific language for writing sane low-to-no-js web pages or parts of web pages without having to manually fiddle with HTML or CSS in any real amount.

Static site generators honestly get me a lot of the way there but those are unfortunately template based which means any significant customisation requires dealing with the HTML and CSS rather than being able to just describe the layout and behavior I want.

Honestly I'd just write the compiler/lang myself if I didn't hate frontend so much.
> Cloudflare doesn't execute workers in all their PoPs.

Yes we do!

> I'm in central Mexico and my workers execute in DFW even though there's a Cloudflare PoP not even 30 mins away from here (QRO).

I think you will find that even if you turned off Workers, your site would still be routed to DFW. Some of our colos don't have enough capacity to serve all traffic in their local region, so we selectively serve a subset of sites from that colo and reroute others to a bigger colo further away. There are a lot of factors that go into the routing decision but generally sites on the free plan or lower plan levels are more likely to be rerouted. In any case, the routing has absolutely nothing to do with whether you are using Workers. Every single machine in our edge network runs Workers and is prepared to serve traffic for any site, should that traffic get routed there.

(Additionally, sometimes ISP network connectivity doesn't map to geography like you'd think. It's entirely possible that your ISP has better connectivity to our DFW location than the QRO location.)
> Sure but it's not high at all.

It depends. For a sysadmin maybe not, but for data scientists, the bar would be pretty high just to understand the math jargon.

> If perplexity can tell you exactly what to do 90% of the time without error

That “if” is carrying a lot of weight. Anecdotally I haven’t seen any llm be correct 90% of the time. IIRC SOTA on swebench (which tbf isn’t a great benchmark) is around 30%.

This sounds cynical on its face but it is my experience as well. Management does not actually trust engineers to provide value without close oversight (sometimes with good reason!), so any framework that purports to give engineers more autonomy will eventually be subverted by the management. And since management always has more power than line engineering, they always win.

The only way for "true" agile to really take root would be for management to trust engineering to add more value on their own than when being micromanaged. That's a tall order, and gets much taller in larger organizations.
Nice app, I really like the idea! Let me know if you need help getting the Android app through the closed testing, happy to install and test!
I find Zach(tronics)'s take on this in KOHCTPYKTOP much more pleasing somehow.

Of course, it's difficult to play now, since the webpage [1], and steam version relied on flash, and you have to fiddle with a 3rd party flash reimplementation.

But its implementation of semiconductor behaviour is much better than wireworld's.

They don't make pink slime by grinding up ribeyes.

My initial assumption is that they acquire some IP in bulk, monetized what they could in better ways and then were left with a couple D rate pieces that they happily loaned out to anyone willing to make a buck with them on the condition they get a cut. It just so happened that "anyone" was a less than upstanding party.
Oligarchs have always had full control in America. They've chosen to exercise that in an especially conspicuous way, but in the end, a bunch of people went into the voting booth and pulled the lever labeled "felon".

The oligarchs have a huge thumb on the scale, but it's not mind control. As Mencken said, "Democracy is the theory that the common people know what they want, and deserve to get it good and hard."

Maybe we will indeed get it good and hard, and four years from now we'll reconsider. That won't do much good for the Ukrainians, who will almost certainly have suffered a genocide, but we decided that apparently we're good with that.

Or maybe we'll muddle through, like we did last time. The fact is that a President has only limited power to affect your life directly. Yeah, there's every reason to think that erecting a massive trade barrier will crash the economy, and trashing the federal government will cause tons of misery in the "get your government hands off my medicare" crowd. But we have the sour grapes that the new leadership is at least incompetent, and rarely accomplishes anything he sets out for.

I'm extraordinarily disappointed that Americans have chosen literal criminality. It's hard to imagine that we said "Yeah, nearly everybody around him was convicted, and the first thing he's going to do is pardon himself, but at least he's not..." and I'll let you finish that sentence.

But that's not the oligarchs, at least not immediately. We did this to ourselves, at least in aggregate. A lot of people are going to get hurt who didn't do this to themselves, and all I can do now is try to mitigate that as best I can.
So the halting problem is solved? I don't think so. Let's continue to make software better without resorting to impossible claims.
It depends on what you mean by "rare". Both PETG and PLA were commercially available when RepRap started, but they weren't very widely used. PLA's biggest use at the time was reabsorbable medical implants, for example. I don't know what people used PETG for in 02005. I'm not sure either of them existed in the 01970s.

Android uses SELinux.
If you like this, you may find automation project engineer work fun... or at least familiar. Function block diagrams are quite like this: There function blocks are connected together with wires, and the order of operations is defined by block order. Blocks themselves are like builtin functions in the engine, or they can also be composites. The diagram is executed once per control cycle and generally (if no jump blocks exist), each block is always executed exactly once per control cycle regardless of if their inputs have changed or not.

And that is how control logic for anything from breweries to petrochemical plants is implemented! Fun stuff! I happen to work on the UI side of an FBD-based control system, so I float around this stuff day-to-day.
> no one in embedded actually cares what RTOS you used. they are all similar enough that you won't get stuck if it's a brand new RTOS

Out of curiosity (as an outsider), how does the availability of device drivers factor in?

I assume they still need to be ported to each combination of OS and device.
Show HN: ProdshotAI – Affordable Product Photography
Hey Hacker News!

I was on the hunt for good AI product photography and ended up diving deep into researching it myself. Played around with different models and training techniques, and after wrapping up my project, I thought others who aren't super technical might find it useful too.

That's how ProdshotAI was born – a service that offers affordable product photography. You provide the input, we train a Flux image model, add some LoRAs, and deliver the product images you need for anything you’re working on.

It’s still a work in progress, but we’re constantly improving the results.

Would love to hear your thoughts and any feedback!

Dotcom is really expensive. It prices out entrepreneurs who aren’t independently wealthy or take on usurious venture capital terms.
I don't think you can get a mass market SSD that does what this thing does. Not unless you change some parameters. The speeds and bandwidth you get is always with full encryption for all blocks. That might not be special to you, but doing this mass market in a way that doesn't make exploits and bypasses appear faster than the manufacturers can patch it (looking at TCG, BitLocker etc) is definitely special to me.

As for that other methods may work (making the chain longer by introducing a separate bus, two transceivers, an additional controller from another vendor, extra firmware, extra power buses), they have done that in the past. In practically every shape:

- SCSI
- ATA/IDE
- SATA
- NVMe over custom physical port before M.2 was broadly available with the same specs, but probably also cheaper for them

They also have had drives in all sizes as well, both internal and external. That includes most forms of modularity (external: entire drive + enclosure, just the drive or just the enclosure, internal: 5.25, 3.5, 2.5, CF-sized) and controller wise they also have done all variants: add-in card, on-board, on-chip, third party controller, first party controller, combinations where they did only the firmware or only the hardware, ones where the fabric and the controller were combined etc.

So technology wise, it's not like they haven't gone back and forth with many, many combinations.

Business-wise:

> I'm not convinced there's any purpose for the way Apple does their storage aside from vendor lock-in.

First of all, I highly doubt Apple gives a shit. Their model of lock-in is making a better combined experience than the competition. If they could do that with some random western digital black SSD while making the same amount of money, they would do it. But more importantly: if Apple would do that, they would still charge you $1000 for that SSD, even if it's only 1TB. The concept of lock-in is making it so that people don't want to pay the cost of leaving. You can't lock people in with just the stick (an SSD-shaped stick with a $1000 price tag) if you don't have a carrot.

Secondly: I don't want or need to convince you, but trying to shoehorn a business in such a one-dimensional take is not exactly a good way to spend your energy.
When people start to spiral over something that was said in politics, I often think of this from the HN guidelines:

> Please respond to the strongest plausible interpretation of what someone says, not a weaker one that's easier to criticize. Assume good faith.

I’m going to assume good faith, and do my best to not take on the anxieties of others. That doesn’t mean blind trust, but I don’t think it will be as bad, or as good, as people are projecting out there.

You brought up politics in relation to different economic class.

My point was how we treat ultra wealthy as a political issue is independent from the underlying reality. They aren’t directly outvoting poor people to revive more benefits, it’s instead a question of influence.

Billionaires tend to see positive ROI from getting involved in politics, which is self reinforcing over time. But, stepping back you can judge such systems not in terms of current politics parties operate, but in the broader context of how efficient systems are. In that context the ROI is negative for society even if it can be positive for some individuals that comes at significant cost.
I wonder how this compares to 'catastrophic forgetting' that can be a problem of full fine tuning. Or at least that's what I've just been reading as a case _for_ using LoRa, as it's not susceptible to that. I guess this paper shows LoRa causes forgetting in a different way.

Are there good general principles yet for what fine tuning method to use in certain situations? It still seems quite difficult to know ahead of time what's going to happen.
Excruciatingly laborious to read as well. The pixel font and line art is quaint but not ergonomic if you have to strain to read it or discern a wire shape. We left that stuff behind in the 90s when high res displays arrived.
Yes exactly. The AI crowd are the ones not arguing in good faith here. The title is very confusing as it stands right now.
You only need a 20ish pound set of weights to build muscle, oddly. Don't even have to spend a ton of time on it. Can do a basic set of curls/whatever while cooking breakfast.

Body weight exercises feel like they should be even easier to do, but realistically are a lot harder. Pushups, are free and can be done anywhere, sure; but are not a place to start at.

You don't become a $3tn company by respecting and liberating users.
Eh to a certain degree. The architecture of the models is very much control theory and then the training is control system tuning (which of course is an optimisation problem like you said).

I would definitely agree that optimisation fits the definition in part but I find really only control theory covers that entire field of signal processing, optimisation, and decision making systems.

And importantly, because ML in some amount touches on all of those, control theory tends to fit better as it focuses so heavily on providing a comprehensive framework for reasoning about all of those elements together.

The Ruby syntax looks increasingly appealing to me. Does anyone have Ruby book suggestions for experienced programmers? I'm looking for something close to K&R or APUE style, preferably also with some coverage of Ruby's C-API.

It does not have to be ultra modern or up-to-date, correctness and best practices are more important.
Brief moments of clarity is pretty common in people with Alzheimer's. Having worked with elder care, there were lots of moments where people who usually didn't speak at all and were mostly confused, suddenly started having conversations and seeming to understand where they were, and then some hours later, being back in the state of utter confusion.

Doesn't surprise me that some of our greater minds of our time would have a similar experience, but with a even stronger contrast.
Thanks for the advice. Potentially, it's not insanely farfetched to assume AI and math (currently doing math) can unlock more precision with less data and invasiveness. While it's at one level physics, stronger algorithms and analysis can maybe reduce the size + cost + danger of the hardware, as well as require less data for more precision. Just a hunch. There are always plenty creative ways to experiment without animal harm as well, just a matter of attention and will to explore. Yeah, safety is super important, and if this sort of scanning can be made better in a fresh way that would unlock a lot. Just like having a 10x cheaper API that does the same job automatically becomes useful in new unforeseen ways.
Oh I don't know. Go read a single article about women's birth control and the extreme effects it has in a woman's body and often personality? Also, self empowerment? Also, casual sex and condom use is notoriously not perfect. Curing many STDs is easier than, again, the larger burden that women carry when contraception fails.
