@xmal An LLM just spits out tokens at constant speed, while I need several days to find a good first sentence for a paper 🙈

When you ask ChatGPT to illustrate TLS 1.3

@MohamedElqdusy Security of crypto: you need to prove that it's extremely unlikely to solve for any input.

Complexity classes: don't care about probabilities as long as for every algorithm there is at least one hard input.

[Peter Zeller @peterzllr]

@MohamedElqdusy I think P=NP is a different problem than security of crypto algorithms. For example,
there are harder classes than NP that are proven to be strictly larger than P. One example is EXPTIME.

Still that would not help to prove security of a crypto algorithm.

@ajay9470 Besides the missing *, there is a potential null pointer dereference as the result of malloc is not checked.

[Peter Zeller @peterzllr]

@ccanonne_ That's one reason why I like formalized proofs: References to other publications (libraries) are actually checked and it just needs one click to go to a definition.

[Peter Zeller @peterzllr]

@gunnarmorling F# type providers might be useful if this is about typing based on external information. And TypeScript is quite good if this is about typing string literals.

@ChShersh Semicolon insertion in Go: https://t.co/cRTFzu3wZY
Very simple rules, but works better than the more complicated rules in Javascript, Scala, Python, or Haskell.

@AlexKontorovich Syntax, axioms, and proof rules are invented. Theorems and proofs are discovered.

@tagir_valeev How did you even find this peace of code? Does Jetbrains scan GitHub for weird looking code? 😁

B: Just set up a free service for an AI based assistant and collect confidential data millions of people send to it.
C: And then what?

[Peter Zeller @peterzllr]

@lemmster Running TLC and then ChatGPT. Sounds like a very resource intensive type checker.

[Peter Zeller @peterzllr]

@ttforall Types are the dark matter of computer science. Someone made them up so the math adds up.

[Peter Zeller @peterzllr]

@martinkl Google "solved" the synchronized clock problem with better clocks, so I assume they just solve the RPC problems by building a reliable network 🙃

[Peter Zeller @peterzllr]

@eatonphil I've never seen a (non toy) compiler that does this. Any examples?

[Peter Zeller @peterzllr]

@anne_biene @skogsbaer So cool. May I ask why checking filtermap take so long? Is it because of the recursive definition or because of the union types and pattern matches? Would it be easier if the implementation of filtermap accepted just "false | {true, Value}" as return value for F?

[Peter Zeller @peterzllr]

My favorite commit message when working in untyped languages: "fixed type error".
Then looking at the commit log I can see how much time I would have saved with a proper type checker.

@xmal @g_unis @ashokerCS Congratulations! 🎉
