cant believe hearing this from a productivity youtuber.
for me, the apple ecosystem provides great convenience when context switching (music, papers, books, etc) from one device to another (heck, even the airpods switch automatically when you switch to a different apple device)

there is technically some "cheating" because the paper uses a floating-point number with arbitrary precision.
Since the amount of bits required is very low(!) this paper is a good candidate for compressed representations maybe. But its definitely not a "single" parameter.

I don't think Musk is interested in moderating/censoring/etc any academic tweets, so leaving academic twitter seems to be a bit of an overreaction. thoughts?
I sincerely hope people in my communities don't leave Twitter. I think there's a lot of value in it right now, and it's unlikely to be reproduced on another platform. And I fear people preemptively moving may permanently splinter the community.

AI influencer clown literally just googled "hardest CS/math problems" and equated them to an admission at MIT/Stanford 🤡
if you prove P=NP, MIT/Stanford would be the last place u would be going to
Unironically think we can solve most of our problems by just assigning elite university admissions bounties
-> solve Riemann hyphothesis -> guaranteed admission and full ride to MIT for you and 6 others of your choice
-> p=NP -> Stanford for 10

a few days ago I discovered (or learned) that for positive numbers x and n, if n is a power of 2, x%n is the same as x & (n-1)

The problem with open dialog (what I've heard from my friends who regularly submit to ICML,NeurIPS,etc) is that it leads to reviewer fatigue, and they end up not responding at all.
I think a single rebuttal round is fine, as long as there is a per-reviewer character/page limit.

Another lesson from Presentation Zen that I've found useful!
@SenguptRoni
It all starts with preparation. I highly recommend storyboarding lectures/talks in analog format first. I use sticky notes to first brainstorm and then organize them into a story.
The biggest mistake I find most people do is rush to their presenter software, that comes LATER.
