I haven't owned one of their devices, but it seems like Linus[1] is not satisfied with their current situation.

Just look for a phone on which you can easily install a stable custom ROM. I previously had a Samsung device and installed Lineage OS and was happy-ish. It was clean and free of bloatware, fast, and had a good battery life. The downside was that it wasn't stable (probably never got an uptime above 48h) and the major updates were too buggy and too late.

I recently bought a Xiaomi device. The moment you turn it on you notice it's filled with spyware and bloatware. I thought I couldn't be more surprised after seeing the clock app ask for permission for "personalized experience", but they got me, in the calculator app. Other than that, the hardware is great, the themes look good, and overall it's a good experience. It's a pity I'd have to switch to a custom ROM because of this "personalized experience" MIUI nonsense.

They just found a way to cure "cancer"

I came up with another solution (which is purposefully complicated): It is known that the sum of n-th roots of unity is zero. So if we choose the n-th roots of unity as ω and calculate Σ ω^ai, the result should be 0 + ω^(the duplicate number).

So I opened the python interpreter, and I used this very trivial method of calculation (instead of summing the sine and cosine functions independently), and using asin and acos functions, got the result. It turned out to be accurate for n=1e6 with an error of ~1e-5. So it should be usable for much bigger n too.

Gymnastics doesn't seem to be useful either. Maybe we should stop people from doing that: They almost certainly injure themselves, and even if they don't, who benefits from someone doing a 180 split?

I don't like baseball either. The game sucks. It doesn't help with productivity either. Students should be discouraged from playing that too.
