looks like educated in west world doesn't make these folks more........democated?
maybe one day chinese people will be like Uyghur people, hated by most of the world, force to leave their country, seeking a land to live, and this DID happens before.
(Let's remind to people don't know history of china, lots of regime in mainland china are foreigner from outside, ex: 唐(dang), 元(yuan), 清(ching), and its close to be fully occupied by Japan in last centry. If not Japanese gov decided to hit Pearl Harbour, there will be no CCP dominated in mainland China now, and we may speak Japanese and rest of mainland China will be like a giant colony of Japan)

Turns out any site that allows users to submit and retrieve data can be abused in the same way:
- FacebookDrive: "Store files as base64 facebook posts"
- TwitterDrive: "Store files as base64 tweets"
- SoundCloudDrive: "Store files as mp3 audio"
- WikipediaDrive: "Store files in wikipedia article histories"
I wonder if we could use this technique at place which gov will censored senstive data upload to streaming site like mainland china or North Korea(they do have streaming site right?)
although for propganda use, shortwave / sat tv is a much much simpler way to distribute information to place like that, but I belive now its hard to get one SW radio for anyone.

The question reminds me of Susan Rigetti's recommendations for math self-study. If your goal is to self-study the equivalent of a university undergraduate mathematics degree, this is one approach: https://www.susanrigetti.com/math
his recommendation is quite useful, I've read most of it and found most of them are approachable
momofarm commented on Finding Center of Gravity in Backpack johnnycabin.xyz/... · Posted by u/momofarm
What I am trying to solve is that when we go throghhiking / multiday hiking, we will carry a lot of stuff in backpack(around 12kg ~15kg). If not pack properly, the backpack will pull back, even worse the muscle will get hurt. Some even have hip bruise.
By get the pack right, you can have a more comfy trip, and best of all, save some bucks to (not) buy a new pack (if you are lucky)
there is another weird phenomena I seen on online forums.
Normally, get a not so comfort backpack should quite common, I knew lots of people try lots of backpacks and just can't get the right one. I suspect most of them is because of they pack their bag not (physically, or said in mechanically) wrong.
But I rare seen related content online, only few have issue with bruise hips. (hips!? really, how much you carry could cause bruise hips?)
I wonder if the search technology nowadays are broken (I use google, but sometimes I pay some visit to duckduckgo but get quite the same result)
