🏃‍♂️It is that time of the year when Chennai weather starts turning into a sauna for a couple of months. This is at 5:30am! 🥵

Thanks. These stats are not available in Public. Let me poke people at IITM.

This is the distribution of enrolled students in the first batch of online BS programme from publicly available info: drive.google.com/file/d/158VS....

Finished much faster than anticipated. 1:40:xx. Laser cut personalised medal is a nice touch.

Not bad for first time running in the hills; 15k with 500m climb at 2600m.

Only 10 minutes slower than my usual 15k morning runs in Chennai. Guessing regular runs at 25+C 85% humidity is good training.

PSA: Zotero is the best paper reading / bibliography management app today.

* FOSS.
* Highlighting + comments actually work.
* Has previews of references, figures, etc.
* IPad app that can be annotated with Apple Pencil and syncs to the desktop app.
* Has a notion of tags (collections)

If all goes well, OCaml 5 code will ride into space in < 24 hrs.

I can see that 15 is what works. But it feels odd that such a low setting should work.

When interpreted by the book, if the memory used by the program is 115MB, the working set is 100MB. However, given that with 15 it matches OCaml 4 spacetime behaviour (with space overhead 120), reality may be ..

Great work from @tarides.com folks on pragmatic verification of OCaml software.

Chosen as one of the distinguished papers at TACAS 2025.

Saw Nilgai and grey langur in the wild for the first time. Didn’t realise langurs are much taller and have much longer tails than bonnet macaques.

And plenty of peacocks too.

Just checked into IITGN guest house. Already impressed with the aesthetic. It is like.. they employed an actual architect and a designer.

Accidentally brought my wife's MacBook to work. Had to teach a class where I live code F*. Devcontainers + Github CodeSpaces saved the day.

Good work by my past self taking pains to containerize this part :-)

~35 folks turned up. 2x larger than our previous largest meetup. OCaml was discussed; pizzas were had.

Need to work on improving the diversity of the group for the next meetup.

Aalok Thakkar is teaching Introduction to Computer Science at
Ashoka University using OCaml. The course looks great: aalok-thakkar.github.io/teaching/ics... 😍

OCaml 5.3 has been released: discuss.ocaml.org/t/ocaml-5-3-...

It brings syntax support for effect handlers.

It also brings back statistical memory profiler and MSVC support.

Did a 1/2 in 2:10 this morning. Was aiming for 2:15 or better. Quite happy with the result.

Ran this distance after 6 years. 15 minutes slower than the last race.
