Today at 3:30PM PT at PLDI: Rupicola, my thesis project! Come by (or join us virtually!) to learn about building domain-specific compilers that generate efficient C code from functional programs, with proofs🐓☑️. Paper (OA): https://t.co/IWWKRgg9SY, Code: https://t.co/NKTvCiOz5R

Students: I'm recruiting, come work with me! https://t.co/5iEWP1sHou

I got a job and I'm moving! I'll be joining the faculty of @ICepfl in Lausanne, Switzerland next year. I'm very excited and humbled to be joining such a great department, and I look forward to working with many awesome students and all my peers at @EPFL_en and beyond.

@PDVLcc :) Thanks! Generating the C++ models takes (mostly) linear time in the size of the designs, so ≈ 0 for our examples. Compiling the C++ at -O3 can take time (a few seconds per 10ksloc?); -O2 is faster (the models are decently compact and they don't tend to trip GCC).

I just presented Cuttlesim 🦑 at ASPLOS 2021 :) Cuttlesim is a new simulator and debugger for our rule-based hardware design language, Kôika. In a 🥜🐚: you can get much faster simulation and much nicer debugging by *not* compiling to Verilog. https://t.co/UW0lfYYjCr

Just released! Alectryon is a literate programming toolkit for Coq and also a compiler from Coq documents to interactive webpages. Blog post at https://t.co/cnTtEbi89s, repo at https://t.co/rYYQf2dOGD, and academic paper at https://t.co/jIQbIj3u7X— come to the SLE talk tomorrow!

[Clément Pit-Claudel @cpitclaudel]

My lab has a new blog! The focus is on our research, so lots of Coq proofs, systems, and compilers, a bit of hardware, and some tutorials and even guest posts! Right now we have Coq tips, a guide on captioning talk videos, and an Iris intro. https://t.co/ILmIMt2mDa ✍️🐓✅

Our IJCAR2020 paper just got published! https://t.co/sjq4cwh3Aw. We show how to build flexible & verified domain-specific compilers, with an emphasis on performance, to get end-to-end proofs connecting high-level mathematical descriptions to assembly. The talk is on Wednesday.

[Clément Pit-Claudel @cpitclaudel]

Our PLDI 2020 paper is out! We present a formal semantics and a verified compiler for Kôika🦑, a new rule-based hardware language. To evaluate it, we wrote performance proofs and ran a small #RISCV core on FPGA. Check it out at https://t.co/cIzXeHHWWN & https://t.co/QUcaWsJN0W

@johankj not sure what you mean; can you post an example in a Github issue?

[Clément Pit-Claudel @cpitclaudel]

Dafny (a verification-aware programming language) is on GitHub now! And MIT-licensed. https://t.co/OaKfmUvqxf

Looks like @microsoft's #Cortana wants me to freeze to death.

@edent the safest, of course, would still be to actively participate in the web of trust and get your key signed by plenty of people.

[Clément Pit-Claudel @cpitclaudel]

@edent List it on plenty of websites. For Alan Rusbridger, the simplest would probably be to print it in the paper edition of Guardian.

[Clément Pit-Claudel @cpitclaudel]

@edent @damuffinman @francibosco they don't need to. They get the key from untrusted sources and check it against the (trusted) fingerprint.
