Here's a guy playing with a supercritical CO2 pressure vessel on a table (seems a little brave to be shaking something at such high pressures!) https://www.youtube.com/watch?v=2d7RGQMCX24
There is a Help->Rules link on all of the puzzles linked here. It can be a little tricky to decipher them if you're coming to them completely brand new, however. I mostly use them as a refresher.
I actually had a concurrency bug that I was able to capture with rr: an MPI job where I only ran rr on rank 0 and managed to figure out where a different send/recv ordering was causing issues. In fact, it was also a Python model that ties in with a lot of native code generation, so quite a complex issue.
I thought it might work a little like the NYT sudoku app: placed numbers delete candidate notes automatically, but you can also manually toggle candidates on/off. I guess a once-off generation would probably work to achieve this?
What is the backend for the storage buckets we see in cloud (and increasingly, HPC) computing? Seems like a database filesystem would be a good fit there.
I have seen a few roundabouts with metering traffic lights that are only enabled during peak traffic times to occasionally allow the “blocked” directions in. It seems to be a reasonable compromise.
This is of course only the administrative/management levels. The staff doing the actual teaching and grading are lumped with all the work “as part of the job”, and also the money doesn’t see the post-grad or research sides of the university.
I've been using Firefly III (https://www.firefly-iii.org/) since it came up on HN a little while ago. It's aimed more at the budgeting/personal finance side of things rather than a full accounting solution. I like that you can enter things like expected bills, so you can get a bit of a look forward, and good breakdowns of your spending over certain time periods.
This sounds fascinating! In HPC environments how do the images communicate -- I'm just assuming there's some form of distributed computing going on there?
