Is there any niche of vendors somewhat equivalent to free software zealots in Shenzhen? E.g., "you can boot this little keychain thingy without blobs."

There's plenty of free software thieves (the GPL violating kind) in Shenzhen. Sadly, there isn't a goddamn thing we can do about it.

Go ahead, try enforcing the GPL in China. They'll just laugh in your face whilst trying to sell you the next shoddy widget on AliExpressazon.

That's not how autocratic systems work. In any autocratic system you allowed to be somewhat independent. How independent? It depends on you position in hierarchy. But if you cross the line, you will get punished for all your independent actions and even thoughts. There is no "because of this and that". The only thing that matters is that you crossed the invisible line.

I get the impression that Western companies (and Chinese companies with non-disposable brands marketed in the West) can have GPL enforced against them.

For example: https://sfconservancy.org/activities/

I know one of the other dynamics is when the GPL copyright holder is more of a crunchy-granola hippie guru, who might just want to lovingly bring the lost soul into the fold, because they know not what they do.

That's really not a deterrent to the people who know exactly what they're doing.

Personally, I'd like to see copyright holders be less flower-child toward abusers, and more like a Scout who was helping an elderly person across the street, when they were attacked by a group of violent racists. It's not time to turn the other cheek, but to grab a heavy stick.

I think many Chinese companies freely share code between them, regardless if it's open source or not. They just don't care about licenses and IP the way the West does.

So, if you want to get the source code for X, you just have to learn Cantonese, go there and ask nicely.

As a former good Cantonese speaker, now terrible, let me assure you that there is no way to ask anything nicely in Cantonese. It's a rough-and-tumble, loud, crude, obnoxious gutter language. It's awesome. So much better than Mandarin. There's a reason why Cantonese is always the go-to language for "misc bizarre foreign language spoken by asians in the background" in movies, well that and the very high number of first-rate actors available from Hong Kong's movie industry. It's my favorite language in the world.

>> Since ... 2016, the population of Shenzhen has grown by over 2 million people, the metro system has added over one hundred kilometers of track, and dozens of new stations have been opened. The city’s taxi and bus fleets were converted from gas to electric. The entirety of Huaqiangbei Road - the center of the electronic market district - has been torn up and replaced with a pedestrian boulevard.

Holy crap. As a Brit we have recently spent 100 billion and twice that time to fail to build a railway between two cities, London still runs almost all petrol bus and taxis and ...

As we have (hopefully) an election coming soon and might see some change I would be interested in why the UK - who about 150 years ago woukd have growth stats very similar to that - has got well, meh.

The usual suspects for such terrible performance are

- much lower starting point. It's easier to setup mobile phone masts than replace the POTS.

- too much regulation (from safety to public consultations that allow NIMBYism to slow things down)

- we are not growing - if the number of people buying mobile phones in year X is twice the number of people who already have a phone, then you can see a different market than if everyone keeps their phone for one extra year. Does something else play out for cities, streets and factories?

- just money coming in. The UK is having serious lack of growth and presumably shenzen is not.

Or is it, that "ooomph" ? a level of belief that tomorrow will be better?

Yes. Also, rules and regulations on expropriation of land, relocation of people etc, with plenty of long appeal processes.

China? "Go away or else".

southerntofu

I don't know where you live, but in France and surrounding countries expropriations are certainly "go away or else". It's very common for the cops to evict people for industrial projects that have been found illegal by tribunals, and it's not unheard of that the mafia itself beats up small owners until they "give up" their land. It's also common for people to get maimed protesting industrial projects (lose an eye, hand, foot due to military grenades), and not unheard of for them to die killed by the State (Vital Michalon, Rémi Fraisse, etc).

In France, most appeals processes you can have when your eviction has been decided can in fact not delay the eviction. You can be evicted before having your appeals hearing. The Grand Paris has already expropriated so many small owners (from popular districts) for the olympic games madness, and it's so common for farmers to be expropriated away from their lands to build crazy useless projects, such as the NDDL airport where residents had to defend themselves with molotov cocktails against more than 500 riot cops trying to destroy their homes back in 2012.

So, maybe it's better where you live but please don't pretend the West is a marvelous land of human rights. I'm of course not saying China is a dream-like State of human bliss and safety ; they're a tyrannical regime crushing their population. I'm just saying if you scratch the surface, it's not wildly different here (although comparatively better in some regards).

While mainland China's land ownership is more like a series of 99-year leases, those leases are notoriously difficult to break. There are loads of examples of buildings in China being built around a few land holdouts. In fact, it's so common that real estate developers in China call them "nail houses[0]".

There are a lot of contributing factors:

1. Shenzhen is sort of a tech center of Southern China so it requires good and new infras

2. Local governments are economically and politically encouraged to build infra (Google 土地经济) in general

3. Infra is built faster and cheaper in China so Shenzhen is not an outlier. Usually it starts with some planning to build a line in a remote area (to save buyout costs) -> line gets built -> other infrastructures including super markets, post offices, whatever get built -> apartment buildings get built -> government gets paid back by taxes collected from real estate companies, super markets and other expanded economy entities

4. Some cities actually lost the bets on building new infras and this created a whole range of issues (Google 地方债 and 地方融资平台公司债)

A well-know thing is, rebuilding things was a fairly common (and for some, important) method for the local gov to raise funds.

One instance in our city almost 10 years back, they built a perfectly acceptable 4-lane city road, and then completely rebuilt it again just few years later.

Of course that method is no longer be used as wild as it did under chairman Xi and his uh... successful economic policy which greatly reduced the need of roads. But things are bit different back in 2016.

Real time voice translation is getting really good. Standard text translation is pretty much perfect for technical details, but just may miss idioms. You just have your smartphones out, type your message, and show the translation to the other person. They read it and start typing on their phone, then show it to you. I got through China pretty painlessly this way, and it is so normal for many, especially the young. I went to one restaurant where they got the younger waiter when they saw me walk in, who I thought would speak English. She just knew the phone text translation ritual, but was an expert in that.

But for millennia, people have gone to far away lands where they don't speak the language, and somehow managed to build trade routes without even having a dictionary or calculator. It is not that hard to work out a pidgin. Tons of things you can do with pointing and gesturing. Marco Polo would have killed to even have Google Translate circa 2010.

I'll also assert with no evidence that it is generally harder for an English speaking engineer to successfully communicate a technical idea into business speak for English speaking VC investors than it is for an English speaking engineer to communicate a request to buy a specific part to a Mandarin speaking engineer.

I've never done this in China, but I've done it in Vietnam (before I learned more of the language) and in Japan.

It is surprising how much you can communicate by drawing circuit diagrams, sketches of oscilloscope traces, and equations! It works quite well!

However one problem I encountered was that many (maybe most) vendors were not engineers and had no understanding of the parts sold. They just knew the name of the parts they had in stock, and how much they could sell them for, and that's it. Often they weren't even being paid -- it's a family business and they were just the niece or nephew that got roped in to vaguely watching the store while playing games on their phone.

This was much more of an issue in Vietnam (Nhat Tao market) than in Tokyo (Tokyo Radio tower). In the latter there appeared to be quite a few retired engineers who were quite enthusiastic to meet someone who was looking for something specific. It was pretty neat, and I occasionally encountered someone with a wealth of knowledge!

She tried to enforce the GPL on a Chinese company and the mainland Chinese government threatened her with... something. Speculation is rampant. Naomi had a Uighur wife, and mainland China is both homophobic and currently doing ethnic cleansing of Uighurs in Xinjiang. In fact, her wife isn't even allowed to leave the country, so it's entirely possible that they said "shut up or we jail her".

The way that authoritarianism[0] works is that there are two sets of laws. The real laws are secret and ever changing. Sometimes they will change for just one person. The published laws are the excuses and punishments they will use against you for violating the real laws you were never told.
