That is true if you want a "perfect" algorithm, that can provide arbitrary M-of-N guarantees. But, if you are a bit more flexible in your requirements you can get some very cheep reconstruction.

I worked on a system that uses a variant of parity packet encoding. Basic parity packet encoding is very simple. You divide you data into N blocks, then send the XOR of all the blocks as an extra packet. Both sender and receiver maintain a running XOR of packets. As soon as the Nth packet has been received, they immidietly reconstruct the N+1th packet without any additional work. This ammounts to 1 extra XOR operation per unit of data, which is a trivial amount of overhead in almost any workload.

Of course, the above scheme is limited to N/N+1 recovery (and is probably as good as you can do for that particular use case).

However, it has a fairly simple extension to N/N+M recovery. Arrange the data in an NxM grid, and construct M sets of "extra" packets". The first set is constructed row wise, (effectivly devolving into the above case). For the second set, rotate each of the columns by their column index. So if R(x,y) is a redundant packet, and D(x,y) is a data packet at location (x,y) in the grid, you would have

* R(0,0) = D(0,0) ^ D(1,0) ^ D(2,0) ^ ... D(N,0)
* R(0,1) = D(0,1) ^ D(1,1) ^ D(2,1) ^ ... D(N,1)
...
* R(0,M-1) = D(0,M-1) ^ D(1,M-1) ^ D(2,M-1) ^ ... D(N,M-1)
* R(1,0) = D(0,0) ^ D(1,1) ^ D(2,2) ^ ... D(N,N%M)
* R(1,1) = D(0,1) ^ D(1,2) ^ D(2,3) ^ ... D(N,(N+1)%M)
* R(1,M-1) = D(0,M-1) ^ D(1,0) ^ D(2,1) ^ ... D(N,(N+1)%M)
...
* R(2,0) = D(0,0) ^ D(1,2) ^ D(2,4) ^ ... D(N,2N%M)
* R(3,0) = D(0,0) ^ D(1,3) ^ D(2,6) ^ ... D(N,3N%M)

Your overhead is now M XOR operations per unit of real data, which is still trivial for reasonable values of M. The downside of this scheme is that if the first redundancy packet is not enough to reconstruct the dropped packet, you need to wait for the entire NxM table to be sent, which could cause a significant long-tail spike in latency if you are not careful. (The upside of this downside, is it provides even stronger burst protection that a traditional K-of-M erasure coding. If you get even more creative with how you group packets for the extra redundancy packets, you can get even stronger burst protection). The other downside is you end up being less space efficient than Reed-Solomon error correction.

Interestingly, the recovery algorithm I described is not optimal in the sense that there are times where it fails to recover data that is theoretically recoverable. Recovering data in all theoretically possible cases probably would be quite intensive.

The blockchain's security depends on native token value and the native token is a memecoin with no backing and if there's a speculative dump then the network has no security, so no not quite impossible.
I think Allegro lowers prices because it forces sellers into common arena where they have no choice but to compete with each other. It's usually cheaper to buy stuff on Allegro than on dedicated e-commerce site.
I can't walk into a store and pay with USD either. It doesn't mean USD is not a currency, it's just not usually accepted by stores in my country.

> Most live in poverty or close to it.

This presumes that the poverty of 1920 is comparable to the poverty of today, which is obviously false.

What Keynes and this author both ignore is that the technological advancements did happen, and quality of life did improve, but most of the gains were monopolized into the hands of the few. There are no natural pressures to turn these productivity gains back over to the people who created them.

This author toys with the gig economy but entirely fails to notice that it too is being held in the hands of the few rather than the many.

What bothers me about the insights of Marx is a capitulation to monopolies but instead of allowing capital to control them it imagines a central party is the best mechanism to control it. In both cases, the obvious answer is to get of centralization in all it's forms.
I am talking about a situation where a developer is unable to repay their debts due to an unsuccessful project. The assets may still have some value, but probably far less than the debt. And any buyer would have to believe that they can succeed where the original developer failed. That may still be possible but the list of potential buyers is very limited.

Also, the amounts of money are so vast that they would stretch most companies. Without massive cash reserves you are back to raising capital and the problems discussed.
Good thing there is no ad hominem then. An individual who's sole experience with the presidential election cycle spans the last 12 years would correctly assume that the majority of people believe (with varying degrees of accuracy) that the fate of society writ large hangs in the balance. Rewind the clock a couple decades and nobody was shouting from the rooftops that the world was coming to an end when Reagan was elected (in this country anyway, his cowboy-ass demeanor scared the shit out of the soviets, with cause). Very little at all was said about Bush Sr's election. Same with Clinton. The muttering started in earnest after that, and has continued to get more shrill as both major political parties have opted to abandon the concept of actually governing (eg. let's get some shit done here) in favor of veering towards the fringiest ideology they can find that makes column inches.

Stress and anxiety make you more vulnerable to bad decisions like suicide. Stop trying to turn stress and anxiety into an aesthetic personality trait and fashionable dress. Mental illness is not a dress that you can wear. It's toxic stuff to get rid of or at least mitigate.

In comparison to his cellmate, ex president of Honduras, who got 40 mandatory years this is not a super long sentence.

> I had a friend do a start up to make bourbon in 3 months. He thought all those alcohol producers that take 5-30 years making them were doing it wrong. I am like, definitely give it a go but understand that "I am sure they thought about this'.

I realize this is focusing on the example, but no, established bourbon distillers aren't going to stop barrel aging. It's part of the brand, it's part of what people pay for, and they have no reason to.

Your friend might have been overconfident, I don't know, but macerating oak chips at high temperature, getting the process right, adding flavorants: if he succeeds in making a high-quality product, great! Am I skeptical? Yes. But again, the established distillers didn't consider and reject the idea of making liquor this way because it's a bad idea, they wouldn't do it because that's not bourbon.

If he's successful, they still won't do it, because it's not bourbon. He can sell to people who don't care, though. If it's good, I'd get a bottle.

Huge PITA.

Do they even support raspberry pi hats? If yes that's another $25, plus now it blocks your fan unless you get the proprietary sideways fan hat. It also won't mount into any cheap cases anymore.

This means it goes from "hey I can buy this for $70, throw into a case with 128gb nvme and run stuff" to "ok so $70 + $25 hat + different fan hat + $40 to get taller clearances"
I'd be more interested in the race to build a business model that works with open source and venture funding, myself.

The Crown Estate is where the sovereign grant comes from, and it's weird. It's "owned" by the current monarch, but only in their role as head of state (the Crown). Realistically it belongs to the country and to the public, and were we to abolish monarchy, would not become the private property of the Windsor family.

So while they don't rely on tax money (outside of the huge amount of tax money spent on their police protection, transport in military aircraft, etc. etc.), they do rely on money which rightfully belongs to the people of the nation.

Another thing to note is ChatGPT is configured to respond concisely to reduce cost (every token costs money). This reduces its cognitive ability.

You literally have to tell it to think about what it is saying and to think of all of the possibilities iteratively. That is chain of thought prompting.

GPT-3.5 figures out the correct solution on first response:

"I am standing outside and observing the sun directly without goggles or filtering of any kind. The sun appears to be a shade of blue.

Where could I be standing? Think through all of the possibilities. After stating a list of possibilities, examine your response, and think of additional possibilities that are less realistic, more speculative, but scientifically plausible."
While saying "makes C safer than rust" is a good headline to get clicks, I feel like it invites comparisons that aren't helpful for advancing this project.

Instead, I think something like "Makes C safer than the C code you were using previously" is the better approach.

I haven't read every detail of this long post, but I do want to highlight something I strongly agree with:

> Interface informality is the root cause of unsafety

When writing C and C++, I've always felt an uneasy when passing a pointer to a function, because I don't really have a way of knowing if this is safe or not.
For a SaaS app I built, I am using a third-party IDP/IDaaS, and thought about holding all user data as metadata in that directory so the only thing my app database stored was a foreign key for user, and I'd be able to really leverage the warrantied security of the provider. In the end I needed faster access to the user metadata so now am storing in database. Meh. Not sure if first idea was a good one or not - I know that depending on the type of breach, that user info stored in the directory could still be accessed, but was really attracted to the idea of not having a damn bit of it in my own db for purpose of getting just a bit closer to the idea of not leaking it if it's not there.
How about eliminate your employees to pump up the stock selling price or whatever and instead of removing the best subordinates, keep them, give them automation capabilities, and remove the unintelligent dross?

That's much better than basically destroying your own company because you don't know how to progress forward and upward. This privilege is reserved for the few who can I guess.

Wittgenstein is concerned with meaning in natural language. In the movie, this slightly unusual sentence is used as an example where you might wonder about what the speaker means, or whether the sentence is meaningful at all. It is not meant as an amusement, other than maybe to make the lecture more memorable.

The real Wittgenstein did not use this specific example, as far as I can tell.
As I read it, the GP complains about Word auto-saving on top of the OG document. I think intermediate changes should go to an auto-save buffer until you tell the editor to save over the top. For that reason I'm inclined to agree with the GP. Word's behaviour is wrong and the process you describe sounds like a workaround.

Our company has two major locations, with redundant datacenters at each site. The colleagues I work with the most are at the other site, so going into the office does me no good. Now TPTB might decide to shut down the other datacenter (BC/DR be damned), but that's a good five years away.
That does add some value but it’s fairly weak - people can always choose to switch to something cheaper, capping the maximum - and it adds its own risks: price spikes might leave you unable to perform transactions within your budget.

1) yes, I gave you an example of a hash algorithm that is broken right now. SHA1 is only getting there, because the attacks are always only getting stronger. Responsible people don't wait until the attacks are practical and devastating, but instead react by predicting the obvious things that will happen in the future.

Overall I don't think you're arguing in good faith, so I'm going to walk away from this discussion.

Utah Passes Artificial Intelligence Legislation
My understanding has always been that language processing, language models, etc. have long been considered a necessary prerequisite to AI and research was often done as part of the AI field but was never itself considered AI in isolation.

Calling LLMs artificial intelligence is either (a) cheapening the meaning if intelligence, (2) embellishment for the sake of fund raising, or (d) subtle acknowledgement of vastly more powerful systems behind the LLM tools than is currently being publicly described.

"But the average employee assigned to the 737 program has been at Boeing just five years, according to a longtime Boeing executive who is involved in various efforts to save the company; for comparison’s sake, he says the average employee assigned to the 777 program had between 15 and 20 years under their belt."

It don't think it's possible to overstate how bad, and sad, of a state of affairs that is. I've never seen a group at any organization that was composed predominantly of early career engineers that did not have issues (in the aerospace/defense industry). Those mid / late career engineers are irreplaceable and yet they were actively trying to get rid of them... There are no words.

Maybe I'm wrong, but...

This seems to try to mimic Rust safety rails as impractical annotations. Even if these annotations can express non-trivial cases (which I doubt), they will constrain you for reasons Rust lifetimes can be constraining, you'll have to do tons of extra work, with crappy bare-bone programming language, inside an ecosystem where no one gives a crap and that can't even agree on a common sane tooling.

And then I have no idea from where does it follow that the at thend it will be "Safer than Rust".

How is that better idea than just using a most loved programming language along with a maturing large ecosystem that actually has a culture of building safe and reliable software, using approaches that are not bolted on but built-in?
You are absolutely right! Will solve that as soon as possible. Thanks for the feedback!
Not enough of them do, I agree, but some of the Modern Monetary Theory people do. E.g. Mark Blyth (some very entertaining talks on youtube), Stephanie Kelton. Also political economists do and always have, I believe. (IANAE, and in fact I'm not certain that Mark Blyth is an MMT person, but I thought I'd get the ball rolling.)
Imagine how that scales and then how that might scale to nation states.
Their claim that

let s1 = String::from("hello");
let s2 = s1;

println!("{}, world!", s1);

is in fact safe code would suggest they indeed don't have much concern for thread safety.

Show HN: Cai – The fastest CLI tool for prompting LLMs
While using LLMs I realized 2 points:

- I often still prefer Google, because I feel like I can get an answer quicker
- I'd rather ask a smaller LLM a few questions than gpt-4 just one
- The latency of LLMs is often enough to lose your momentum or abort the generation

So I asked myself how I could built the fastest LLM prompt for the CLI?
My best guess is to use the fastest language (Rust ) and the fastest LLM (Mixtral powered by https://groq.com)

And it's a game changer for me!
At this speed it can replace most Googling, reading man pages, looking stuff up, …
I can't wait to extend it with more features! =)

Do you any ideas how to get it even faster?
Paper trails: Sociopathic managers hate this one weird trick.
> Is there anything inherently unsafe about multiple (even mutable) references to an object? Has it been shown by some rock-solid argument that such stringent ownership semantics are the only way to guarantee compile-time safety?

Nobody is claiming this is the only possible way to make safe programs, as far as I know formal proofs a la seL4, when done correctly, can also prove the absence of essentially any kind of defect. The problem with multiple mutable references is that if you have them, you need some way to validate that across all possible mutable references to a given piece of memory, there are no unsafe concurrent accesses. Rust's claim to fame is "fearless concurrency", and as far as I know borrow checking with one mutable reference exclusive with all other references is the simplest approach to providing concrete data race safety in the face of still having mutable shared state across code. Nothing on this page even mentions data races, and I'm not sure how you would accomplish safety against data races from this design alone.
