[D] Understanding principle component analysis (PCA) - From scratch!

2021.12.04 20:09 thebrittleguy_ [D] Understanding principle component analysis (PCA) - From scratch!

In this blog post, I have explained PCA from the ground up. Using some basic principles of Linear algebra and probability, I slowly arrived at the optimization problem that PCA solves internally. The blog is now published 🤗. Have a look!

2021.12.04 20:09 garvyledges Help with automation request: turn certain notifications ON at work (opposite of focus modes)

I’ll start by saying that I doubt this is possible. But I would be remiss if I didn’t ask, just in case.
Right now my default text message alert sound is “none”, but I still have text notifications on, so my screen lights up if my phone is in front of me, but the notifications don’t distract me if my phone is in my pocket or in the other room. I don’t want to leave DND on all the time, because then I won’t get any notifications at all.
When I’m at work, I would like a text notification sound if people I work with text me. It’s actually pretty much the opposite of how the new Focus Modes work.
Do I have any automation options here?

2021.12.04 20:09 warpath15 Fun and interesting learning objectives for a escape room game

Hello everyone!
For a university project, I'm creating a small educational game and I am looking for some fun and interesting learning objectives that I can incorporate into the game (the goal for it to be an escape room style game)! If you have any ideas on how you think it should be implemented in the game, feel free to share!
Thank you in advance!

2021.12.04 20:09 gerrypoliteandcunty Ian Urbina (NY Times) scammed more than 400 musicians and is earning royalties through a proxy record label managed by his wife

This is huge news and needs more attention. He basically contacted thousands of musicians pretending to be interested in their works and promising a ton of exposure and future revenue but never delivered and misled the artists by never mentioning the record label that would be earning the royalties was being managed by his wife.

2021.12.04 20:09 iforgotmy_username17 Terminally ill in-law, how to prepare? Maybe a difficult case…

Long post and some details changed for discretion!
I, 25 F and married to a 31 M. I am Canadian and been here 2 years, and now applying for my FLR. I am on a marriage visa (this isn’t relevant I feel but just in case)
My mother in law who was not married has terminal cancer (it’s everywhere) and possibly not long to live. She is typical antivax, sugar kills, organic only type of person and is in denial that she will die (was in denial of her sickness until recently)
We can’t bring up anything cancer related and she thinks she will get better but she won’t. My husband and I take care of her. Like I work less days and my husband has been working half days for 3 months as she can’t be home alone nor can she care for herself.
I have no idea if she has a Will. I have no idea what plans she has for when she passes. She is only 51. Who plans/pays for the funeral? I can’t ask, it’s not my place at all! But if the topic even breaches convention she shuts down completely. Any topic about cancer at all!
She is a director of a interior design company with less than 5 members My husband and I live in a cabin behind her house, but since he was 19 he and his mother have shared ownership of her house. What happens then?!
What should we expect and what can we do for what is to come!? We are scared and powerless and we all have a lot to deal with!

2021.12.04 20:09 ValtronW Mom is convinced she's going back to work and it's causing problems

My mom is 68 years old and is showing very clear signs of dementia (I made a post a few days ago). For 30+ years, she worked as a family therapist in private practice. She also taught at a local university and was very active in her professional organization. But she hasn't seen any clients in a couple years and was sadly let go of by the university a year ago after receiving very bad student reviews (we assume because of her dementia-like symptoms).
The current issue is that her and my dad are paying for her office where she use to see clients. They have wasted thousands of dollars because she keeps saying she'll go back and see clients soon. Whenever my dad brings it up, she shuts down and says she'll work on it next week. She refuses to partake in telemedicine, which she could do at home, and insists on continuing private practice My dad and I both know this is a pipe dream, but there's no reasoning with her. Unfortunately, the office is under her name, so we don't know what we can do to get her to let it go other than snoop behind her back, contact the landlord of the building, and try to get a lease termination form for her to secretly sign.
Any suggestions? We're desperate.

I read recently that Paradox finally fixed the late game performance issues where time slows to a crawl, but I couldn't find anything about it in the official patch notes? Is this still a thing and if so, what do I need to do to fix it? Thanks, haven't played in a few years and would love to experience a large map beyond 2400 or whatever.

2021.12.04 20:09 kyocornbear Any advice?

I've been looking at telecasters recently and I've really only got one question before I make a decision:
would single-coil telecasters like the classic vibe or the affinity series be able to perform well enough for metal with the proper effects? i love their clean/crunch tones but idk if i should also look into finding a similarly-priced guitar with humbuckers for that instead

2021.12.04 20:09 FMBPChase Who created the rings of Chasca? Is there anyway of knowing?

Chasca is a planet in the Matano system of the Maroon Sea cluster. It's said to have a ring around it made of synthetic material. Has there ever been any explanation of this? Who could have constructed something so insane and what could its purpose be?
