My interpretation was that the actual mass of the bob doesn’t contribute to the period of the pendulum. I suppose it could shift the centre of mass somewhat relative to the mass of the rod?

Sure the specs are better on other devices, but it comes down to what you'll actually use. Being so tiny I can just toss it in my pocket, and read a few pages with no effort. It's like having a fancy notebook: you end up being very intentional when you write in it, but you'll happily jot something on a scrap of paper without second thought.

That's kind of the way Tangled works, right? Although it's Yet Another Platform so it's still a little bit locked in...

How does Gerrit manage this? Are the comments associated with the source content, instead of commits?

Why not?

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.

Maybe a PS/2 touchpad that is triggering (a bunch of) interrupts? Not sure how hardware interrupts work with RT!
Re:rr – record and replay debugger for C/C++ on Sunday July 21, 2024 @06:48AM (#41024072)
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.
Re:Show HN: Sudoku with 0 Bells or Whistles on Wednesday February 01, 2023 @11:07PM (#34621925)
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?

Re:SQLite: 35% Faster Than the Filesystem on Sunday January 15, 2023 @04:14AM (#34388005)
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.

Even if they don't have the claimed sleep-related benefits, surely they can't cause any harm (except for slightly orange screenshots!)
Re:Should traffic lights be abolished? (2021) on Thursday September 15, 2022 @05:24PM (#32858645)
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.
> that lines the pockets of university staff

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.
Re:How to take credit for someone else's work on GitHub on Monday February 28, 2022 @04:24PM (#30505329)
What about if somebody clones a repo, then adds a .mailmap pointing all the addresses in the history to their own?
Re:Ask HN: Who wants to collaborate? on Tuesday February 01, 2022 @06:19PM (#30171099)
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?
I think it might only be around for another couple of years -- Telstra is switching theirs off in 2024, and Optus is pretty soon too.

You could probably even add another zero (almost two) to this

Re:Fortran.io – a Fortran Web Framework on Wednesday January 22, 2020 @08:10PM (#22123882)
Multidimensional arrays are first-class in Fortran, so there's no need to use pointers there. There are some rules around pointers and subarrays that I expect make any possible aliasing undefined behaviour.

Re:WebDAV (2010) on Monday February 25, 2019 @07:46PM (#19251055)
FastMail gives me 10GB of storage that's accessible via WebDAV. It works perfectly to back my collection of papers and textbooks in Zotero. That way I only sync the metadata to my Zotero account (which is basically just a sqlite database anyway), and can pretty easily get access to my entire reference collection from wherever I am.

How do you handle answer changes owing to different environments/compiler versions?
From their readme, USD was considered but OBJ was chosen "for expediency."
Re:PicoLisp on Wednesday May 02, 2018 @07:27PM (#16982049)
It's not quite readline, but if you start the interpreter as `pil +', you get better editing and history and some nice things like `(doc 'sym)'
