Why don't we just use lat long coordinates or geohashes for addresses? The shit that delivery people have to put up with is truly ridiculous.
This article is largely unfair. The city has large swaths of sidewalk established as bike parking zones. I can almost always find a bike zone within 10-50m. Furthermore, there are almost always parking attendants and security guards outside of malls and subway stations ensuring that bikes are parked correctly. Even when these people aren't present, I rarely ever see bikes anywhere but the bike zones. And as much space as the bikes take up, it is NOTHING compared to the parked cars along the streets.
Furthermore, I see company trucks collecting and relocating bikes multiple times per week. They are constantly shifting bikes of high supply to areas of demand. There are certain times of day (eg Saturday night at the Bund) where there are untold legions of bikes, but car traffic is flowing well.
Many of the trips that I've taken on a Mobike were out of convenience. In American cities the fastest mode of transportation is almost always a car. However, because the bikes are essentially door-to-door with no delay, I can almost always beat a hired car because there is no delay and I can zip between waiting traffic.
Chinese cities are being strangled to death by the crazy growth in car traffic. There has been insane immigration to cities and average income has gone way up. The net effect is a lot more car usage. Every taxi driver I have complains about the ever-worsening traffic conditions, year-over-year trip times increasing etc.
Bike sharing does A LOT to alleviate this by providing a convenient, quick, and cheap ($0.10-0.20 / 30min) method to travel. This is all ignoring the obvious ecological impact of the many tons of CO2 not released by the saved hydrocarbon fueled trips.
These differences are nonetheless not my biggest grief with China. The moment you restrict criticism of your institution, you have committed to sacrificing pragmatism for ideology. Pragmatism requires commitment to the truth, which can only come from the status quo being continually challenged.
The Eastern desire to require "harmonious thoughts" is so at odds with the skepticism required to birth true innovations. I was once convinced that China was on the verge of becoming a new force in modern technology. But after seeing a long line of regulations meant to increase the echo of their political echo chamber, I doubt technological innovation can linger much longer.
Amazon owning 19% of "prime-office space" is even remotely comparable.
EDIT: grammar
Furthermore, the fact that Apple has just pulled VPN apps from its App Store and the unfortunate fact that you can't sideload apps makes iOS an untenable OS choice.
In summary of the motivations of the paper: PoW is currently limited to cryptocurrencies as a security system because of the implicit financial incentive in mining coins. This approach could allow PoW schemes to be widely adopted to secure systems as the overhead is lowered dramatically. Additionally, battery powered devices (ie phones) could make use of PoW without incurring large battery drains. This last bit is particularly interesting and could allow some interesting, distributed P2P systems on cellphones to arise.
The general principle of the paper revolves around asking network members to prove computational power only as much as necessary as the network scales. Because an attacker could easily spoof their MAC / IP address when joining the network, computational tests are periodically distributed to network members. If the test is unsolved in an allotted time period, their network membership is revoked (and the node is blacklisted). The attack referred to in the paper is an attacker adding bad (fake or otherwise) nodes to a system rapidly.
I have previously tried to investigate why Kubernetes was considered useful [1], or why everyone was losing their minds over Docker [2]. But rarely came away with any clear insights.

Also, why are you celebrating an alternative for WebKit? Isn't it already supported by most major browsers?
Again shooting from the hip here, but given the restricted environment of the web browser, it would seem difficult to believe that you could make a high performing full game given that you need to download THE ENTIRE GAME essentially every single time you play, no? So that restricts the size / complexity I would wager.
Every technology company that I've come across in China has invested a great deal of effort into establishing stable VPN connections. I have seen several "VPN microservices" that act to tunnel all foreign-bound traffic out of the country. In the vacuum of mature, western technologies many Chinese copycats have popped up. I have been hoping that we would start to see more and more Chinese technology companies exporting their technology [1]. With these new legislative actions, it seems like a step in the wrong direction.
I'm struggling to come to terms with the restrictive policies that the Chinese government continually struggles to hoist over their citizens. During the midst of one of the most dramatic periods of economic development in history, the Chinese government is moving to artificial isolate themselves from the developing global economy?
