I will soon start microblogging again about academic life on bluesky. Goodbye Elon. I wish you all the worst.
FP folks -- please encourage recently completed PhD students to publish their dissertation abstracts in the Journal of Functional Programming: simple process, no refereeing, open access, 200+ published to date, deadline 29th November 2024. Please share! tinyurl.com/jfp-phd-abstra…
The Applied Category Theory Adjoint School 2025 is coming! golem.ph.utexas.edu/category/2024/…
FP fans - 11 new PhD abstracts have just been published in the Journal of Functional Programming, with links to the full dissertations! doi.org/10.1017/S09567…
St John's College Oxford is currently advertising for CDRF (analogous to a JRF) in CS. This is a great opportunity: basically to be a postdoc on your own project rather than someone else's. sjc.ox.ac.uk/discover/vacan…
Picturing Quantum Software is a brand new book covering state of the art methods in quantum compiling, circuit optimisation, classical simulation, and fault-tolerant quantum computing using the language of the ZX-calculus. Get the preprint for free: github.com/zxcalc/book
Interested in learning about compiler calculation? Check out Patrick Bahr's great talk on our paper at #ICFP in Milan this week: tinyurl.com/53uvyjxy. The paper is freely available from: dl.acm.org/doi/10.1145/36….
Revised draft paper with Ralf Hinze, with many improvements. Formal monad theory, calculational reasoning with string diagrams, and lots of colourful pictures. Now featuring this funny robot like character. On my website as too much for the arXiv. stringdiagram.com/wp-content/upl…
Back to drawing string diagrams, this time related to commutative squares of adjunctions. Just two iterations of a proof step that intuitively slides a twist around a bend. Also evidence I seem to be turning into some sort of retro wallpaper designer.
I'm delighted to announce that the next Midlands Graduate School (MGS) in the Foundations of Computing Science will be held 7-11 April 2025 at the University of Sheffield, UK. Further details will be announced as soon as they are available. cs.nott.ac.uk/MGS/
I'm hiring a postdoc to work with me at the University of Kent on programming languages, tools, and systems for climate science in partnership with @Cambridge_ICCS jobs.kent.ac.uk/Vacancy.aspx?r… Closing date 9th September 2024. Potential topics include:
I just put a new version of my book on a category-theoretical approach to Formal Language Theory onto my homepage. It includes two new chapters on power sets and distributive laws. fi.muni.cz/~blumens/ALT.p…
I have a new blog post comparing exponentials with their fixed point encodings in linear logic on The Proof Theory Blog: prooftheory.blog/2024/06/27/exp… . Any comments are welcome!
Interested in joining our project on semantics-directed compiler construction? @danghica is advertising a 3-year postdoctoral position in Birmingham, UK. Please share, and pass on to anyone who may be interested in applying! Closing date 11 July 2024. lists.seas.upenn.edu/pipermail/type…
An enjoyable day pushing to get our second string diagrams book finished. Really just drawing colourful pictures in the garden.
E.g., should the string diagrammatists be reading more Peirce, or should the @symbolica people be reading Ernst Cassirer? Here's the link to attend online: teams.microsoft.com/l/meetup-join/…
The 2024 Alonzo Church Award for Outstanding Contributions to Logic and Computation is presented jointly to Thomas Ehrhard and Laurent Regnier for giving a logical and computational account of differentiation, bringing Taylor expansion to the Curry-Howard correspondence.
We are still looking for talk proposal for SREPLS 15 / CW. This will be in in Canterbury, UK, on the 18th-19th of July. Participation is free, but you need to register. cw-srepls-24.github.io Functional programming/Category Theory talks highly welcome ;)
The proceedings of FLOPS 2024 are free to read and download until end of June 2024. You have to get there via the conference website: conf.researchr.org/home/flops-2024
