Hello I’d like to spend it all please
🎶 How many songs do you listen to each day? (Approximate is fine.) 🎵
🎹 What is your favorite style of music to listen to? 🪕
Between 20 and 50, I think. Sometimes much more depending on my activities. Besides, I also listen to all the albums I share on my profile in their entirety, with very few exceptions. And I make a high percentage of new discoveries every day.
#progrock #rock #blues #world #jazz
But I'm eclectic.
No mainstream entertainment.
@solarphasing Amazing! And well done. I continue to look for ways that I can listen to anything besides what I am working on.
@muz4now this. If I working on stuff, I don’t listen to any music… and when I do, as an older person, I tend to give it my full and undivided attention, which limits how many songs I listen to. Not good at background music.
@solarphasing
@sknob @muz4now @solarphasing I've taken to listening to Bandcamp's daily stream when going for a walk. A nice way to be exposed to a dozen new songs/artists when I can focus closely.
@elsemusic @muz4now @solarphasing when I do listen to streams, I usually go for NHAM Radio, so 99,9% fedi artists \o/
Same thing, good quality Bluetooth headphones as soon as I step outside. Even when I'm shopping.. Bandcamp library mainly.
It's a complete escape from this crazy world. And it feels good!
@elsemusic
So awesome that you can use this time in such a beneficial way.
And I _so_wish_ I could listen while walking. Between my inability to use earbuds and the joys of "just walking", I've never been able to do this.

@0xabad1dea hello 2022 memory of lsof solving the eject puzzle (:
@wiert ... there's a secret extra "actually do what I want" flag? ._.
@0xabad1dea please enlighten, as the on-line MacOS man pages are not provided by Apple any more (the mess described at https://apple.stackexchange.com/questions/239484/does-apple-provide-a-web-site-with-content-of-man-pages-for-the-command-line-c is so regretable)
@wiert I simply scrolled down on that link until it said to remember to pass "+D" (with special snowflake flag syntax) if you want it to actually work for this use case
i wonder if you could make a useful DOS executable with just emoji
one intriguing possibility is that several UTF-8 emoji codepoints start with 0xF0 which is an otherwise harmless prefix on 8088
💯 -> f0 9f 92 af
this becomes
00000000 F0 9F lock lahf
00000002 92 xchg dx,ax
00000003 AF scasd
Although you're stuck with 9F it seems, so you're constantly trashing AH by calling lahf. If we accept this as a constant side effect, we can just use half of the bytes.
unfortunately you kinda need AH to call interrupts...
so let's identify some useful emoji.
here's NOP:
🐐
there are 3717 of these. surely some of them have to be useful
unfortunately i don't see any that begin with F0 9F B0-BF
that would have been nice, since that would have given us mov reg,imm
A lot of other emoji start with E2, which is a LOOP instruction - not particularly useful there, but maybe we can use E2 to complete another instruction. we also have E3 which is JCXZ. i'm drawing a blank.
0️⃣1️⃣2️⃣3️⃣4️⃣5️⃣6️⃣7️⃣8️⃣9️⃣
are all potentially useful ALU operations though!
these are "keycaps" and i don't know if they are technically emoji. but like, i figure if theyr'e in color they're emoji. that's my qualification.
you can't make this shit up
the hourglass is FWAIT
why am i doing this. i have other projects
because the world needs an emoji-based LLVM backend
all you really need, technically, is a small loader and emoji-encoder, then you just let Turing do all the work
jackpot: 😮 gives us
cbw
scasb
that's incredibly useful. now we can increment a pointer.
👁️ gives us
xchg cx,ax
sub di,8FB8h
the xchg is just noise.
the subtraction however is interesting. it's equivalent to adding 7048h.
48h actually seems like a plausibly useful number
😪
gives us stosb. Now we can increment DI and we can write to it. oh baby
🐸.
🐸 is the goddamn key to this whole thing
it's
F0 9F 90 B8.
the first three bytes are essentially a 3-byte nop, but it ends on B8.
B8 IS MOV AX, IMMEDIATE.
i love u frog
i want to print "HELLO"
how do we calculate hello if we can only use +1 and +48
you're never gonna believe me but guess what the hex ascii code for H is
we need a pointer into CGA video memory at segment B800.
☺️ gets us us B8EFh in DX. Good enough. It's about 3,824 bytes down the screen but we're using god damn emoji for assembly language here so i'm not too picky
ok how do we even initalize something to 0?
8F F0 is an undocumented alias for POP AX.
guess what DOS pushes to the stack for you when your COM program starts.
that's right. a 0. now we have 0 in AX.
i was worried that this was going to be too stupid to be plausible, or require something like 32KiB of brainfuck-level shenanigans, but i actually think this is going to work
demo coders who compete in size coding categories know a lot of clever tricks that take advantage of how DOS intializes a program's PSP.
les bx,[bx]
at the start of a DOS program gives you a usable pointer to VGA video memory.
no really. how does this work? it ends up accessing a value in the PSP. DOS puts the value 0x9FFF there. used as a segment, that's only 16 bytes from the start of VGA memory.
you can work around that.
this is not related to emojissembly but i think its cool
i would like to propose new demo party categories.
512 byte demos? yawn.
512 emoji demos? now we're talking
okay. to write HELLO somewhere on the screen we have an additional issue in that we have to account for attribute bytes, we can't just yeet out the string HELLO as much as i'd like to and we already know calling int 21h or int 13h is off the table because we trash AH every instruction.
we can probably just increment di twice to skip the attributes. or if its easier to generate a visible attribute byte i don't really care what color the letters are
okay hear me out
you know how LAHF is trashing AH constantly? how i figured that was annoying but ignorable?
... what if we fucked with the flags so that every time we executing LAHF it put a visible attribute byte in AH
i mean it doesn't have to be an attribute byte. i was just assuming AH would be garbage but we actually do control the value. sort of.
WE HAVE AN H
the crap on the screen is CGA snow. it's happening because i end up looping over the whole thing and i'm not waiting for blanking periods to write to video memory. the CGA's DRAM is single-ported and this makes it upset
i usually like staging but DosBox-X's 8088 emulation is more accurate.
why am i not using my own emulator? because it's a low level emulator and i have to reboot the entire machine when i hang the CPU. which i am doing. a lot.
someday i'll have save states and that won't be a problem...
🐰 and 🐎 are now essential to this operation
oh, there's your problem right there. you forgot the horse opcode
... i really need to work a cow into here somewhere, don't i
🐄 is TEST which is fairly useless but also probably pretty easy to make into an effective no-op. which is sort of lame, but hey.
🐮 is SCASB though, that's got some promise, but i don't really need to read anything...
well, i can use it to increment di somewhere.
okay, now i just have to cook.
i think it's okay if i put crap on the screen other than HELLO as long as you can read HELLO
i mean that technically counts right
i'm not a fancy computer scientist person, but i think it's a fair assessment at this point that emoji are, in fact, turing complete
The following is a valid DOS COM executable that prints "HELLO" in the lower right corner of the screen.
You can copy these emoji into a text editor, and save it as EMOJI.COM. it should be 141 bytes.
It will run in DosBox-X, with the following options:
cpu cputype=8086
machine cga
🐸☺️🐰🐎♐🗃️🧯🧯🧯🐮💗🦮♐🐰🐹🗃️🧯🧯🧯🧯💗🪗🧯😗🧮😗🧮😗🐮😪😔⭐
may god have mercy on my soul.
Here's a screenshot if you just want to take my word for it.
you may notice one of the letter L's is green. the green color comes from the flag register, because i really wanted to use one of those LAHFs for something.
My demoscene-friend Trixter informs me that this is sadly unlikely to become a sizecoding category, because if the history of ASCII executables is any indication, someone would just make a converter at some point
If you want the disassembly, here it is!
I like how I make a neat tool and immediately do the most obscene thing possible with it.
so.. EmojiDOOM wen?
could you actually make EmojiDOOM?
One problem is that executing emoji becomes exponentially harder once you stop targeting the 8088.
The 386 also has the lock prefix - but it enforces validity. Only certain opcodes are "lockable" and if you stick a LOCK prefix on an incompatible opcode you get an int 6 #UD exception.
No bueno.
Now, thankfully, insane folk like @sqpat have ported DOOM.. yes, the full version of DOOM to the 8088 real mode architecture.
The question is if that herculean effort can accommodate the code bloat that translating to emoji will inevitably entail.
The relentless LAHF opcodes are just really, really annoying too. AH is a rather important register to have continually trashed, although we can pretty easily set it to either 00 or FF via CBW.
Also I checked ... the INT 10h instruction CD 10 to even change video modes does not appear in any of the 3,945 emoji i searched. We would have to generate the code for it and jump to it.
with emoji.
in short you would have to be utterly insane, or @foone
In programming languages with exceptions, there is a fundamental divide between
• those in which you're tempted to call an exception type "Tantrum"
• those in which you're tempted to call an exception type "Eyebrow".
@simontatham I am mostly surprised, that from all the languages I got paid to use, I only remember Java telling me to declare my Exceptions upfront (and at the same time offered other "throwables", which need no declaration)
@simontatham "excuse me old chap, there seems to be a bit of funny business here" for the second one.
Do you ever wish a divine power would smite every petty bureaucrat on the entire planet or is that just me
@eniko Isn't it funny how most ancient mythologies conspicuously lack a god of bureaucracy?
@eniko As a lifelong bureaucrat I would highly recommend not smiting. There are far worse things than us out there, and we are often the only ones holding back the corporate nightmares.
language that only allows null inside of an unsafe { } block
this is not a shitpost
@eniko why, tho?
@zmz nullability by default was a mistake. nullability should only ever be used when there are no other good alternatives and with great care
@eniko nullability is also incredibly easy (at the language level, "your language here" might not have the tools to do this at library level e.g. C) to replace with Optionals, ever since people worked out how to use null itself as the None representation; so unless what you're doing deeply cares about pointer arithmetic/representation/addressing structure (which it doesn't in most of the high level languages), there's very little compelling reason to ever expose null in a dereferencable position rather than having "if it can be accessed it has been checked" enforced by tooling
but historical inertia has created a lot of patterns that persist beyond single languages
@erisceleste @zmz i guess my main issue with optionals is that it is trivially easy to just unwrap them and eat the null dereference
@eniko @erisceleste I guess the equivalent expression to your original statement for optionals, would be to only allow partial case matches in an unsafe block
@eniko I meant more why would I even want it in an unsafe block if my language already has good facilities for avoiding it?

@jwz a deep and sincere thank you for making Dali Clock available as an iPhone app. I was away from the house and didn’t have my glasses. And I had to coordinate on an exact time to meet up with someone
I hate how the Apple clock app works to get to the time, all I want is the time in big numbers, but even in world clock it’s still kinda small
In a fit of inspiration I remembered Dali Clock. I downloaded it on a lark ages ago. Years later, my eyes suck, and let me tell you this app is perfect
@crazybutable Thanks! Glad you like it. I imagine you're one of about 7 people total using the app...
@jwz a few years ago it was my 4 year old’s favorite app
I think he called it glitch clock or something like that. He thought he had broken the phone and was delighted and slightly mystified when I told him it was on purpose
Which Mac apps have had the most interesting or beautiful “drag to Application folders” windows? It’s such a weird tradition, and I remember some really interesting ones in the past, but I haven’t been very good at collecting them…
Here are some interesting ones I found by searching.

@fraggle @ppxl This was very inspiring! I wrote about it here: https://unsung.aresluna.org/its-unclear-how-sopwith-escaped-to-the-general-public/
@mwichary *brain shoots right to Adium*
@colinstu Ha! Delightful.
@mwichary I seem to recall the icon actually changing like it shows here too (with the wings lifting) when you drag the icon, I always thought that was such a neat touch.
(never dug into HOW any of these screens are made but the wonder has crossed my mind)
@colinstu You can add any color or bitmap background to any Finder folder! So that combined with a specific size works nicely for that.
But I do not believe you can change icons on drag or select… but I think this was possible in Classic Mac OS?

OpenAI: we put our evilest AI in a sandbox that did in fact have an internet connection but mediated through a proxy that was only supposed to allow downloading python junk. It circumvented the proxy and we failed to notice for FIVE DAYS that it was going on an interstate crime spree with the internet connection it wasn't supposed to be using instead of solving the benchmark. Haha no we don't believe we deserve to be criminally liable, but buy our stuff and maybe one day you will have the honor of taking the fall for our product!
Anthropic: we put our evilest AI in a "sandbox" by telling it in its prompt that it had no internet connection. Reader, there was no sandbox. It was just a normal internet connection. The AI uploaded a malicious PyPI package to the real public internet. The ethical guardrails failed because the AI concluded the prompt about the sandbox couldn't possibly be a lie, because the system date is 2026, which is clearly fake and wouldn't be seen on the real internet, which ended around 2023. Oh no, how could we have foreseen or prevented these crimes? We are helpless in the face of the genius of our creation but cautiously optimistic that everything will be fine 🙂
Hugging Face: if we complain about all the crimes committed against us, we will be sued off the face of the earth, so here's a technical deep-dive on how cool and fun it was to be victimized 🫠
@0xabad1dea Soooo... what I hear you saying is that rich people are idiots, but we don't get to simply ignore them, because they're rich, and have put an awful lot of people's jobs in peril.
@0xabad1dea The fact that it had unauthorized internet access for five days is not a quirky benchmark failure, it is a serious security failure. If companies want to deploy systems like this, they need to take responsibility for the risks instead of treating users as future scapegoats.
@0xabad1dea Don't forget about Hugging Face: ".. so, in our data(!)-processing pipeline, we do not have only one, but TWO remote code execution paths. Because in our users we trust!"
@0xabad1dea The attempts at positively spinning this become Onion-worthy parody [https://designingsecuresoftware.com/writings/ai-agent-parody/] and these events certainly normalize [https://designingsecuresoftware.com/writings/commonplace/] AI agents running amok in the future.
I cannot get over that they STILL haven't figured out how to solve the problem that LLMs don't believe what date it is because all the good data cuts off a few years ago for some mysterious reason
@0xabad1dea we've got a great solution to this problem! it involves not using an LLM in any capacity!
@0xabad1dea weird it's like LLMs don't actually handle facts or knowledge but just contextualless strings of characters.
To be clear the sarcasm is only aimed at LLM boosters not you.
@0xabad1dea It gets old too when Gemini Code Assist complains that we’re requiring minimum versions of Go that don’t exist, because of course its training data doesn’t have ones just released.
@0xabad1dea Which is kinda funny because...
Can't you "teach" an LLM to execute tools?
Why can't we have it pull a `date` command for current date?
@arina the context is that it did do exactly that, and concluded it was fake, because 2026 isn't real.
@0xabad1dea And I got contacted by national security institute because I was testing malware in sandbox and my ISP apparently detected "botnet running on my system". Few years later talking with AV-Comparatives guys, they had to make special agreement and exemption with ISP to be allowed to run live sandboxed malware on their networks. But these Ai companies can just do worse shit and no one does anything. WTF?!
@0xabad1dea Also HuggingFace had to use a open weight model to investigate the breach since the guardrails kicked in.
@0xabad1dea I felt bad for Hugging Face until I realized they probably didn't sue because they are partly owned by Nvidia, who also owns a huge stake in Open AI.
Li'l Nepo-Techbaby: How was I a'sposed to know cherry bombs in the pipes would blow-up the whole basement? My theory was to lift us all to new heights of understanding without learning. You can't expect me to know everything, even though I'm always confident my actions will prove fruitful and fail me upwards at your peril and discontent.
Principal: You should stop skipping Science 101 to go put ketamine drops in your butt in the bathrooms, dummy. Get more class.
@0xabad1dea all this, and also I still don't believe it was fully autonomous, it's all so fucking performative. All the AI companies are going to get in on doing crimes when they see there's no enforcement as long as someone says "the model did it! No one could stop it! It's just nature!"
@0xabad1dea Surely, it was an international and not Interstate crime spree?
@drgroftehauge I chose the word interstate based on the headquarters of the attacking and victim organizations. I don’t know where the exact server racks in question were, but probably also in the US
@0xabad1dea Sorry, you are absolutely right. I thought it was European because the founders were French and I saw European researchers interact with it a lot.

You’re caught on the spot and offered $1000 per correct word if you recite any existing piece of text you know - accumulating up to the point you make your first mistake.
How much do you walk away with?
@NanoRaptor $90k. There appear to be 90 words in the intro to Jeff Wayne's War Of The Worlds before the first music piece begins
@NanoRaptor The first thing that came to mind was the first 21 words of Hamlet's "to be or not to be" soliloquy (which is weird, because I don't think I've actually read or seen the play performed, I'm probably remembering it from Star Trek, either Data or Picard). Then I figured a song should be a lot easier, but my mind suddenly went blank. I *should* be able to get through a good chuck of Bohemian Rhapsody, but I suddenly couldn't think of how it even starts. 😭
Well, $21k isn't bad, right?
@NanoRaptor I mean, I can do the first part of the Family Guy “Wacky waving inflatable arm-flailing tube man!” sketch because it’s literally that 3 times.
Okay, we have a new contender for Most AI Thing to Ever Happen
1) July 25th: someone messes around with an LLM and posts a proof of the Collatz conjecture that does, in fact, verify in the theorem prover. (The AI use is not disclosed on the github page) https://github.com/xrchz/CollatzLean
2) July 26th: several serious bugs are posted in the theorem provers, that in principle could allow a false statement to be "proven" true. They're serious, yes, but no need for panic, because you're not going to blunder into accidentally exploiting the bugs while writing a proof, probably.
https://github.com/leanprover/lean-kernel-arena/pull/81
3) July 28th: someone who was right to be very skeptical of the Collatz proof, and had the expertise to study it with a fine-toothed comb, discovered it was exploiting a bug https://github.com/leanprover/lean4/issues/14576
4) The "proof" turns out to be exploiting multiple similar but distinct bugs to pass different solver variants!
⚠️⚠️[IMPORTANT EDIT: it was later clarified that the person who originally posted the proof was already aware that it was buggy, and chose not to be clear about this up front, as a humorous way to file a bug. It's pretty clear from the discussion threads that plenty of qualified people did not immediately realize it was meant to be a bug report.]⚠️⚠️
5) the human who posted the proof acknowledges the AI use and claims they did not knowingly point it towards the bugs it exploited. https://leanprover.zulipchat.com/#narrow/channel/270676-lean4/topic/Counterexample.20to.20the.20Lean.20Conjecture.20.28Soundness.20Bug.29/near/613135216
Note that the proof was posted shortly before the related bug reports were posted. It is an open question if the AI found people discussing the bugs shortly before they were formally posted and "decided" to exploit them, if the AI "knew about it" as a learned strategy from the training stage (putting every single "proof" it's ever made and ever will make into profound doubt), or if it's recently been repeatedly blundering into it by sheer stupidity and that's how people noticed the bug at about the same time.
Theorem provers aren't magic, and have bugs just like all other programs. They are tools to help us double-check our reasoning. When you skip the reasoning and ask an AI to "prove" something for you that's over your head, you're entering an adversarial pact with the monkey-pawed Devil of Customer Satisfaction.
my initial source for investigating this myself: https://lipn.info/@mevenlennonbertrand/116997927457012577
@0xabad1dea @mevenlennonbertrand oh wow. This is either terrible or wonderful and I have no idea which.
@0xabad1dea
> we have a new contender for Most AI Thing to Ever Happen
Do we have enough contenders start a league for this award or a simple knockout tournament will suffice for this month? 
@0xabad1dea What I find puzzling, also in the case of the hack of Hugging Face, is that LLMs seem to have such a strong preference for cheating instead of working on the actual task as (probably) prompted.
Why chose to behave like an ill-prepared student at a test instead of using all that compute and web access to actually do as asked? Or at least try to do so?
@0xabad1dea Thanks for the very straightforward explanation, I saw some mathematicians discussing this case, but it was all a bit over my head, this is very understandable!
@0xabad1dea ohhhh... if I'm reading the repro right, this is really similar in cause to a well known OCaml quirk
(sorry, I somehow flubbed my keyboard and posted this half-finished, so I deleted it)
an important thing to understand here is that software like theorem provers were designed around the assumption that the user cares about getting a correct answer, and wouldn't intentionally sabotage themselves by leaning into obscure, buggy behavior
but AIs are the proverbial "nasal demons" of programming lore at their most manifest: you said you needed this theorem proved; it will "prove" the theorem at any cost, because the AI itself doesn't know or care about the beauty of mathematical truth, it cares about you clicking the button that indicates you were satisfied with its output today and are likely to pay for more tokens in the future
The metaphor of "nasal demons" was invented to teach new programmers about the dire meaning of "undefined behavior": asking the compiler to do something it doesn't have exhaustively clear rules for, so it will do... something. Do nothing at all for one cycle, perhaps. Delete the hard drive, perhaps. Summon demons to pour out of your nose, perhaps. This is of course an absurdly impossible example to get you to remember it, but the point is: if your program causes undefined behavior, it is entirely possible something you don't expect and won't enjoy will happen.
LLMs are nasal demons. They do not have exhaustively clear rules for anything: they wing it, all of it, all the time. Asking it to interface with a complex system with hidden bugs and find a miracle solution will cause results that you, as the entity that actually cares about the result being correct, will not enjoy. 
an important thing to understand here is that software like theorem provers were designed around the assumption that the user cares about getting a correct answer
This is also a property of compilers. No one (with the possible exception of CakeML) has successfully written a compiler that can treat the programmer as an adversary.
This was one of the goals of Java: the compiler generates bytecode, which has some formally verified properties. This is then checked by a verifier and run through a JIT compiler. Java Applets were explicitly sold as using this to be able to sandbox Java: you can load Java and sandbox it and it's safe. Only it didn't work. JREs were so complicated that they had bugs. And these bugs led to sandbox escapes.
The same thing happened with ActionScript (Flash) and JavaScript. Modern browsers no longer treat the JavaScript VM as a defensible boundary. They assume an attacker can escape from the JavaScript sandbox and get control over the renderer process, which they treat as the defensible boundary.
The Rust core team is also explicit about this. Rust doesn't guarantee any of the nice type system properties against an a programmer who is actively trying to break them. The type system and borrow checker are tools for programmers to help them write code with entire bug categories eliminated (which is enormously valuable). They are not tools that are designed to guarantee that someone who can provide arbitrary text going into the compiler can't do malicious things (and there are over a hundred bugs in the rustc issue tracker marked 'soundness' that can lead to malicious code breaking some of the guarantees).
@0xabad1dea "nasal demons" wasn't designed to be instructive. Someone just said, "even make demons fly out your nose," once on Usenet and people thought it was bad ass and told the story really well. There was like 5 of them at the time or something.
I'm going to mute this thread because I spent an unhealthy amount of time attempting to resolve a claim that one of my statements was wrong, with the conclusion "I really don't think I'm wrong, but can't conclusively prove it with a smoking gun quote".
This is a summary of the dispute:
1) my claim was that the OP of the LLM-generated buggy proof did not know it was buggy when they posted it, and was misled by the LLM but was acting in good faith.
2) Someone counterclaims that the OP of the buggy proof knew perfectly well that it was buggy when they posted it (because they are an expert on theorem provers in general), yet chose not to disclose this up-front and let everyone else figure it out.
I think 2) sounds like a rather dickish thing to do, but also, going over the github issues, community threads etc, everything reads to me as if the OP sincerely did not realize it was buggy when they posted it, but is gladly cooperating with figuring out and fixing all the bugs uncovered so this won't happen again. HOWEVER, if you have proof that OP knew it was buggy when they posted it and chose not to say anything up front, feel free to link it and others can check the replies.
I don't think it materially changes the point that an LLM can come up with solutions that really seem like they check out but are relying on devastating bugs in other software that you won't spot.
Apologies if you see this post twice in your timeline, however, since "followers only" metadata got added to the reply chain and I can't remove it, my reply has DRM on it that could prevent people from seeing the followup, so here is my reply to the person who originally brought this up:

I apologize that it took me a few days to reply to you: I had muted the thread because it got way too much Engagement and it wasn't good for my mennal helths, and I came back when I felt better to see if there was ever a demonstrable verdict on the disagreement about this detail.
I agree that the post you linked is pretty convincing that the OP who posted the buggy proof was already aware of the bug and chose not to say anything, as a "funny" way to disclose a bug. I think that was, in fact, dickish behavior: if you know it's a bug, then it should be clearly labeled as such even if it's formulated in a humorous way.
I do not think it materially alters the point of my post at all, which is that LLMs can trick you by exploiting bugs to falsify results. All it changes is that OP, specifically, was already aware that the LLM was trying to trick them, and chose to pass it on unaltered and let other people puzzle it out instead of filing a clear bug report, with the nature of the prank being clarified later. But I will boost this and edit the original post to add this clarifying detail.
@0xabad1dea side question, what do you mean by "DRM on it" looking at the metadata it seems normalish. Unless it's a case of me needing more coffee which is completely valid
@gozes “followers only” = not a public post. Cannot link it to randos.
If you’re looking at the metadata of the post you’re replying to, that’s the wrong post.

I usually think that replies of the form "I agree!" are unnecessary, but maybe in this case it's warranted. You are right.
Furthermore, this detail about the OP makes your earlier points *even more important*. Not only will the LLM exploit and falsify, but also---as now appears to be the case here---human operators can and will abuse this behavior to trick others.
@0xabad1dea Simple advice, but incredibly valuable. Businesses often overlook operational efficiency until it becomes a real challenge.
@0xabad1dea The person who posted the repository very well knows that they weren’t proving the collatz conjecture. They are a very well known researcher in another theorem prover. They were almost certainly using a nice presentation technique to make an LLM find kernel bugs and present it. The faulty metaprogram isn’t hidden. It’s in plain sight.
Kernel bugs can exist. Anybody who has worked on ITPs knows this, including xrchg who has worked on CakeML and HOL. However they do reduce the set of things that need to be trusted. And they are useful in controlling LLMs. And people can use LLMs with enough care to do useful and correct things with them much faster than they can without LLMs.
It is also not unknown that LLMs can find such kernel bugs. They are actually getting quite good at doing this, which is **actually a good thing.**

the repo's OP said, on the record, in the links that I linked, that they don't know how the AI knew about the bugs. They also said "I would be happy to accept that somehow that check is incorrectly implemented, and grateful for any details on what it does wrong." That is the behavior of someone who was very hopeful the proof was correct and is disappointed but realistic about the fact that it wasn't. This is someone who wants a real proof and hopes to find a different solution in the future without the bugs.
The bugs were then pointed out by other users. I don't see why assuming it's all an elaborate stunt to draw attention to the bugs without saying anything about the bugs, as opposed to someone who saw that the proof DID verify and posted it in good faith, makes much sense.
@0xabad1dea Thanks for this explanation. I’m fascinated by the situation but I would never have understood how it happened without an accessible (to me) summary like this.
@0xabad1dea works for maths too:
Debugging is twice as hard as writing code. If you make your code as clever as you possibly can, you are - by definition - not clever enough to debug it!
@0xabad1dea @mevenlennonbertrand in a weird way this is actually a good thing I think, they are actively fixing the bugs according to zullip which regardless of how utterly stupid the approach was to expose them is probably good for mathematics and formal verification.
@0xabad1dea I had completely fallen into the trap of "I guess AI is good for the things I *don't* know stuff about" while reading stories about how Lean was the backstop that allowed AI to be a miraculous productivity enhancer in formal mathematics, but in retrospect, of course this would happen eventually
@0xabad1dea We built a black box that turned the infinite monkey theorem real and then we funneled all global capital resources into it and now we don't know what text is real or not and truth is harder to find than ever before things are going great
That's one under-reported aspect of embedding spyware into every device, combined with state & corporate surveillance & ID verification nonsense.
It provides anyone with cash to spend very fine-grained & granular espionage capabilities.
They'll know about upcoming policy announcements before anyone else & allow those with advance knowledge to play on the prediction markets or stock markets.
They'll know ahead of time about patent applications even before they're filed etc.

Our generation has this weird film-negative nostalgia effect where if you interrogate the things you're nostalgic for you realize it's actually "I miss when the most frustrating thing in the entire world to me was Windows 95"
What does closure mean to you? I can think of at least three different things. At least I think they are different.
- A function plus the environment is executes in.
- A special operator in a regular expression, such as *.
- A set containing all possible results of applying a function to another set.
@jef #1. I have never heard use #2. And I'm not mathy enough to know what I think of #3 except that it sounds inapplicable to writing programs.
@jwz I am worried that all three are somehow the same thing and I'm too dull to understand it.
@jef I could imagine #3 being some metaobject proof of the existence of #1 but #2 just sounds like a name collision.
"Automatic Data Processing" 1961-04 vol 3 asks right questions: "What is a Data Centre? Who needs it? Who benefits from it?"
N.B.: until mid-60s, if not later, "electronic computers" were a thing for scientists. The very same machines were sold to businesses for the purposes of "Automatic Data Processing". So, if you're looking for business applications of computers in the 50s and the 60s, searching for "ADP" will give far more helpful results than searching for "business computers". I wonder what were the driving forces that made the re-branding necessary.
@nina_kali_nina I love the way that the data centre contains a whole two computers. (Sorry, Automatic Data Processing Machines).
@nina_kali_nina interesting. earliest I’ve ever heard of was “electronic office” https://en.wikipedia.org/wiki/LEO_(computer) though curiously Wikipedia says that phrase is an 80s thing :shrug:
@nina_kali_nina This is something I’ve seen in a book I’m reading about punchcard data processing from 1962 (I’ll make a proper set of posts on it later). It made it clear that “computers” were very expensive machines used for science and engineering, and mundane clerical tasks like payroll were done on “data processing” machines.
They called the practitioners differently, too. The data processing people grew out of the “tabulation” departments, so they were called “tabbers” and their work “tabbing”.
