Primary and Cyclic Decompositions

Random post but are there are any applications of these invariant subspace decompositions outside pure math? There was a NASA paper on control theory which involved cyclic decomposition but that was from decades ago. Any modern applications? For example ML related?

Childcare expectations

Is there an unspoken rule that you should proactively offer to help family friends or relatives take care of their children when you are free?

Bringing up the same topic twice

Found out about Uber boats and told my friend about this a long time ago, at least a year ago I think. The other day I went on one myself and sent him a picture of it. He replied “you mentioned ages ago lol”. I completely forgot I told him. Idk do you expect your friends to remember stuff like this even if it’s a long time ago? To be fair maybe I should have checked the chat history first but damn 😭

Poor phrasing?

Friend said “空再联系。也注意休息” and I responded “好的,有空再聊。你也一样”, she then said “好的好的”. I wonder if she got a bit impatient because my phrasing may be a bit odd and sounds jarring? When people repeat the same thing multiple times like “好的好的” it’s either a sign of excitement or frustration?

Childcare

In China is there an expectation to take care of children for close friends or relatives? I grew up in the UK, recently moved to China and I feel like the expectations are vastly different. The other day a family friend (basically sister) asked me if I was still at work and if I had dinner. And she told me don’t work too hard, have more time to relax etc. Then a few minutes later she says “for example if you’re free on a Saturday or Sunday you can help your sister take care of her kids”. I didn’t realise this was something she expected me to think of proactively, although now that I write it out, it probably sounds like common sense. It also wasn’t something she complained about for a long time. I can help but if I do it once she will expect me to do it fairly regularly, and it just becomes a hamster wheel. I am willing to help out in other ways but idk maybe I’m not doing enough 😭

Is it just me or is this bait and switch?

This isn’t strictly an Asian parents post but kinda related.

Convo between me and a family friend. She starts by asking am I still working and have I had dinner, then says I shouldn’t be working too hard and have more rest time, which I agree with. But then she says “for example when you’re free on a Saturday or Sunday you can help me take care of my kid”. I feel like I’m getting roped into this, and the whole “free time” thing is just her way of asking me to do this but dressed up as concern. Also somehow the message feels a bit contradictory, like use my free time to do more “work” in a sense. Although in my case (maybe related to being an introvert and social anxiety) it’s not just about free time, I don’t want to see anyone or do anything on the weekends (I have a full time job) because I also don’t have the energy or mental bandwidth.

She also expected her parents to take care of her kid, got into an argument about it and most people sided against her, but her parents are way older and also live far away, neither of which apply to me. I guess the only thing that still applies to my situation is “her children, her responsibility”. What makes this more complicated is that she has done a lot to help me and my family out when we really needed it, so I do want to help her out. Don’t get me wrong I am willing to make sacrifices and return the favour but it does feel like guilt tripping, and her steering the convo from me working too hard to taking care of myself to taking care of her kid is a bit annoying, and feels like she is dominating the convo. Am I overreacting? Am I being too selfish? Also what would you do in this situation? If I take care once she’ll likely expect me to keep doing it so it’s a slippery slope I feel. If I don’t at all she’ll feel neglected and think I’m selfish. Or should I just try to help in other ways?

Hi does anyone know if there are any places in Shanghai that have casual play water polo (for grown ups) as opposed to training or competitive?

Standing up

Up to now I’ve been riding the track sitting down, did try to stand up but I find it hard to maintain balance on the berms. How do you guys do it? It should get easier with practice but i feel like I’m not improving 😭

Might sound stupid but what exactly is the point of adding relevant uni courses to your cv, for example a stats or optimisation class if you want to go into a math heavy field after graduating, because most of the theory is useless and the parts which are actually useful can just be learnt on the job or through online courses like on Udemy, or even just ask ChatGPT to summarise the whole PDF of lecture notes. What value do they really add to your cv? Is it about showing you have the intuition and/or are interested enough to take them? But interest can be shown in many different ways and taking a module is just one of them. If it’s about showing you can handle challenging ideas, doesn’t the degree speak for itself?

How often do your parents expect you to visit them or spend time with them? I feel like at least half of your free time is supposed to revolve around them? And if not, you are seen as unfilial or ungrateful? Texting or calling doesn’t count apparently and you have to be physically present.

Told my friends about pump tracks and hardly any of them seemed interested. Do most people just see pump tracks as dangerous, boring or a little kids activity? I was hoping to go with them and the one friend who is actually keen lives far away 😭
