"The following is a summary of changes to the Laws of Badminton approved at the Annual General Meeting 2025, and a regulation update approved by BWF Council.

Laws of Badminton – Spin Serve

The spin serve is now permanently banned, as per Law 9.1.5, which now reads as follows:

“the server shall release the shuttle without adding spin, and the server’s racket shall initially hit the base of the shuttle;”"

Wait, I know this one. You give the barometer to the superintendent if he tells you the height of the building.

Not everyone got the Niels Bohr joke that you subtly pulled there.

If life is very common in the universe, then that is probably bad news for us. It means that civilizations should exist that are millions of years more technologically advanced than us; and should be leaving telltale signatures across the sky that we'd likely have detected by now. And the absence of those signs would be relatively strong evidence that life, while common, isn't long-lived. Suggesting that our demise too, will come before too long.

If, on the other hand, life is relatively rare, or we're the sole example, our future can't be statistically estimated that way.

I remember having to implement partial file locking in Minix as an assignment in college. Good times,
jschulenklopper · a year ago
Same here. I adapted the file system to honor user quota, and changed the kernel to support priority process scheduling. We also needed to implemented a change in the memory management part... that ironically I cannot remember anymore.

You are thinking of Noah and the Whale.

You are more likely thinking of Jonah and the Whale.

Here's another approach not mentioned: have an accountability partner. Promise that person something specific to be done, with a delivery date.

My observation: a promise I made to someone else is harder to break than a promise I made to myself.

My approach for finishing projects: team up with a Finisher. I found one at work, and we became good friends along the way.

I'm a typical Starter, and all of the side projects we've been working on together were my idea. All of the projects that we completed and released were solely because of his endurance, discipline and focus. And his constant reminders to not start a new project before the current one was done.

jschulenklopper commented on Is a 'slow' swimming pool impeding world records?   sports.yahoo.com/paris-ol... · Posted by u/phkx

Would the swimmers in the center lanes have any advantage by being furthest away from the wall-induced chop?
jschulenklopper · 2 years ago
And having a better view on the competition in the neighboring lanes (just like in track running). There's even some applied psychology here, that competing swimmers 'push' each other to higher speeds because they can see each other more clearly (and 'feel' the push from someone just lagging).

Putting the faster qualifiers in the middle lanes is also a better view for the spectators on both sides of the pool.

Owen McAteer, https://motus.art/, @motus_art did something similar with the flip-dot displays from AlfaZeta. I have no stake, but I'm a fan of his work.

His code can be found at https://github.com/owenmcateer/FlipDots.

Just wanted to pop in and say hi here! Delighted to discover this thread, it's been quite the adventure trying to get this new version of the book finished. Happy to answer any questions about the book here! Thanks for the support and kind feedback.
jschulenklopper · 2 years ago
Thanks for that book, and congratulations on the second edition. I'm a backer (via Kickstarter - the first project that I supported IIRC) of the original version, and I greatly enjoyed reading that and tinkering with the algorithms.

I hope this version goes as well as the first edition! You deserve that.
