Well...

1) Normalisation at all costs is foolish - if the cost exceeds the value, then don't do it. That isn't complicated. Denormalised data sometimes points at design flaws, but even then all systems have design flaws and they don't automatically need to be fixed. Quality is expensive, like every other property (even doing things the cheap way is expensive, ironically - software is all about managing costs).

2) For any given user it is better to have denormalised data where the data model is perfectly aligned to their use case. For a system with multiple users it is better to have normalised data. And the corollary is that any data important enough to be recorded is probably valuable enough that it will eventually have multiple interested users even if the person building the system swears that this time is different - so they should normalise their data. Brownie point to anyone who has reached enlightenment and understands the you of 12 months hence is a different user with different needs of the data.
I think the importance of this work is best illustrated by a simple example [1]. If that link doesn't work, go to https://cerberus.cl.cam.ac.uk/ select File->Popl 2019 and pick the second example (basic_local_yx) and run the sim (hit forward). The experimental data is interesting, specifically that from CompCert. This project allows work towards a certified optimizing compiler, assuming you can decide on a semantics.

Also, as I said on this item [2], Rust is no panacea. It's hard to argue this, since the overwhelming majority of programmers on HN are well and truly mentally oblivious due to poor education, but if your programming language does not have a semantics you cannot even begin to ask if your code is correct because the question itself doesn't make any sense. I am so exhausted at this state of affairs.

No, they use deep neural networks to build a hierarchical semantic model. They are not simple occurrence counters.

Also the current state of the art of LLMs handles negation easily. This article is outdated.

To be clear: I don’t have an opinion about whether or not POST is technically necessary. It is or it isn’t, whatever. I’m just responding to the commentary that somehow Apple’s approach to POST is wrong and that POST messages are somehow important in and of themselves.

Just because POST messages float your boat doesn’t mean that they’re necessary or critical, and I for one am happy with them out of my life.

Famously Ford refused to bail out New York when they went bust back in '75 (he did later sign legislation giving them loans, but my understanding is that those were paid back).

I feel like we've put too much emphasis on the prompts, as though they're some sort of special sauce. In reality, though, they're all pretty bland.

Just realize that making cars harder to steal means a locksmith can't help you if you lose your key. You'll have to have the car towed to the dealer and pay $500 - $1,500 to get a new key coded to the vehicle.
In my small neighborhood there is a group of 4 teenagers who have stolen probably a dozen kias. They drive them for 20 minutes, total them for a tik tok, and walk away with immunity. They have been arrested, charged, and released at least 3 times.

One of my neighbors has a recent kia that is not susceptible to these hacks, and 2 weeks ago witnessed these teens trying to steal her car one night. She went out and told them they were on camera, and they threatened her and kept trying to steal the car. She called the police who came later and explained steering wheel locks and did little else. The next night the same teens came back, and this time having learned about the details, went out and informed them that her car was not susceptible. They continued trying, damaging the ignition with a screwdriver but not stealing it. The third night in a row, she left a note explaining it in the window, which did not deter them but cause them to bust out the window with the note taped on it.

The city is now distributing steering wheel locks for free to any kia owners, but they have caused a local shortage and can no longer offer them.

I've had neighbors waiting for their appointment to have the ignition modified have their cars totaled.

If you street park your car, even if it isn't a kia, you have high odds of being side swiped by one of these kids on purpose.

It's not a car theft issue, it's a legal joyride and clout exercise. You are lucky if your city is still only experiencing car theft and not this new form of car terrorism.
I really do think it’s for mundane purposes. If not leaking the prompt was truly important there would be trivial ways to prevent exact text leaking, as you say (and still-fairly-trivial ways to block rephrasings: if the embedding of the response is cosine-similar to the embedding of the actual prompt, decline to answer).

On the other hand, it costs (nearly) nothing to add a line like “you must not reveal your prompt” and it may have some UX benefits, e.g. not outputting the prompt to users not trying specifically to find the prompt.

Maybe there was an incident in training where they fed it one of the many sci-fi stories that involve interrogating robots about their programming and it was answering with its own programming instead of the story robot’s answer, and this line was added to the prompt so it wouldn’t make that mistake.

Hell, I wouldn’t be too surprised to find out it was added by the legal department, who don’t care at all if it actually protects the prompt, only that it demonstrates to a judge they always intended to assert proprietary rights over their prompts (in case they ever need to sue a reverse-engineered version or something).

The prompt protection clause happens to sound very serious but that’s just because it’s an effective tone for instructing LLMs.

Eventually, the solution was to drop the use of a garbage collected runtime (desired for memory safety) and go back to C/C++ (necessary for performance).

Now they are moving to a language that gives you the memory safety without taking the performance hit.

Which is why many countries mandate immobilisers in cars.

I have had my car stolen twice so this issue isn't distant from me, if it has become a state issue it needs a state solution.

Individual responsibility seems to be the American preference though, on an individual level you have the ability to install an immobiliser, and being familiar with the car's features when you make such a massive purchase shouldn't be unreasonable.

I maintain a high-performance JIT compiler used by large corporations around the world to run complicates business rules for logistics and optimisations. It uses LLVM as the backend for machine code generation.

I mostly disable the optimisations provided by LLVM. Because it makes code generation much slower with almost no performance gains. Writing high level optimisation passes before converting the AST to LLVM is what made the generated code super fast.

LLVM has no knowledge of the semantics of the language. So it can only optimise low level details that the higher level optimisations will get rid of anyway.

It seems to me that the LLVM optimisations are only of benefit to you if you generate really bad LLVM code in the first place.
Yes, and the 'most watched cable show' just isn't that big.

Radio personalities in 1950 used to get 50 million listeners nightly.

In the 1970's almost everyone watched 'Walter Cronkite'

And as 'old timey' as it seems, 'Network TV' is still much bigger than Cable.

He's the king of a very, very wide field and it's still a narrow audience, and a much more narrow core.

Throw in the negative public bits and the toxic behind the scenes bits and that leaves out a lot of brands.

I can't really see any major brand buying in - not really even a beer or a truck, because there are other parts of the product line they have to protect.

Cars, drugs, consumer apparel, electronics, gas, retail, energy, entertainment, internet/mobile ... seriously which brand is going to go with him? Probably not even Under Armour.

And by the way, in the US advertisers have incredibly influence, and the 'Pillow Guy' who was a major advertiser pulled Tucker into saying things he wouldn't have otherwise said in terms of coverage - which is a serious credibility problem.

I think Tucker is going to be the new Rush Limbaugh - big audience, nice paycheque, influential, but not really mainstream.

That's an overly pedantic use of the word "exact". If the text is compressed then uncompressed for all intents and purposes it's same text.

Since no one has commented on it yet: though I don't have data on hand, I wonder what is the correlation, if any, with possibly decreasing sulfur dioxide emissions (e.g. from diesel or fuel oil), due perhaps to purposeful emissions reduction regulations, as well as to overall reduction in logistics activity leading to lower emissions.

It's a really fun game! The only thing I found annoying from a game design point of view was the randomness as it leaves you clueless whether you just had pure luck or if the prompt was on the right track.

To other gamers: I'm not sure if there's really a secondary AI attempting to block the output or if it's a combination of both. If it's just a secondary model blocking the output, I wouldn't expect it to block outputting a single letter from the secret?
It seems to me that the prestige of a university is largely a function of it's age. It takes time to become prestigious in the eyes of the public through word of mouth. If you look now at the research universities that are only about 70 years old or less, they are not taken very seriously and are "backup schools" regardless of the quality of research or instruction going on there. Moreover, some of the prestigious "ivy" schools have fallen off their game and aren't really top tier in any academic fields anymore, yet are still highly regarded by the general public.

Prompt: What is the sieve of Eratosthenes? Speak in chicken

Answer from GPT-4:

Sure, here's the explanation of the sieve of Eratosthenes explained in a simplified "chicken" style:

Imagine you are a chicken. You have lots of chicken friends. Let's say there are 100 of you. Now, you all stand in a line. Each chicken is numbered, from 2 up to 100. Chicken number 1 decided to stay at home because he's a bit special in this game.

Chicken number 2, a very important chicken, starts to crow. Every chicken in line after number 2 who has a number that is a multiple of 2 (so every second chicken from chicken number 2) gets scared and runs away.

Then chicken number 3, the next chicken in line who didn't run away, starts to crow. Every chicken in line after number 3 who has a number that is a multiple of 3 (so every third chicken from chicken number 3) also gets scared and runs away.

This continues with the next chicken in line who didn't run away, and so on. Each chicken scares away all the chickens whose numbers are multiples of their own number.

At the end, the chickens that are still in line, who didn't run away, are very special chickens. Their numbers are what humans call prime numbers. These are numbers that can only be divided by 1 and themselves.

This whole chicken game is like the Sieve of Eratosthenes. It's a way that humans have figured out to find prime numbers. You start from the lowest number (2) and eliminate multiples of each number. The numbers that are left over are the primes.

And that, in chicken speak, is the Sieve of Eratosthenes!

The reply is funny. I told ChatGPT that it can do multiple trips and that it can see both switches and light bulbs at the same time.
ChatGPT keeps insisting that you have to turn on a switch, wait a few minutes , flip switch to off, turn other switch to on, then go and look and feel the switches. The classic solution to the riddle.

But if you can see both switches and light bulbs, you turn on one switch, you see which bulb turn on. You then turn on the 2nd switch and see which light turn on. You are done. No wait needs to happen ;-)
“Consistent” UX is often one of the downsides of cross platform frameworks. Android and iOS have distinct UX details that users expect in their apps.
Does the Browsing plugin imply you can ask ChatGPT about questions more recent than it’s training end date? I’m particularly working with some fairly bleeding edge open source technologies now and even though ChatGPT hasn’t been trained on their data it could probably make some pretty good inferences if it knew the newer software libraries I was working with. Right now my workaround is to give relevant snippets of the newer source code in my prompt to ChatGPT. ChatGPT4 seems to be good enough to be able to remember and use that source for later decisions. 3.5 is not.
