Hong Kong Protesters Use Mesh Networks To Organize
wabrandsma sends this article from New Scientist:
Hong Kong's mass protest is networked. Activists are relying on a free app that can send messages without any cellphone connection. Since the pro-democracy protests turned ugly over the weekend, many worry that the Chinese government would block local phone networks. In response, activists have turned to the FireChat app to send supportive messages and share the latest news. On Sunday alone, the app was downloaded more than 100,000 times in Hong Kong, its developers said. FireChat relies on "mesh networking," a technique that allows data to zip directly from one phone to another via Wi-Fi or Bluetooth. Ordinarily, if two people want to communicate this way, they need to be fairly close together. But as more people join in, the network grows and messages can travel further. Mesh networks can be useful for people who are caught in natural disasters or, like those in Hong Kong, protesting under tricky conditions. FireChat came in handy for protesters in Taiwan and Iraq this year."
but the ad-hoc nature of it makes it incredibly handy.. i'm not sure if "security" it paramount when you are literally in the shit.. if you're being shot at by the government, who the fuck cares about your texts are in the clear? the point of this thing is to spread the word, quickly... encryption would HINDER info being shared.
I wonder how much information one mesh node could accumulate to incriminate other participants? How many of "the people" will be willing to participate in an uprising like this if they know that a government stooge is likely no more than two or three hops away?
You do realize that most of these protesters are literally standing two or three steps away from a government stooge wearing riot gear, right? It's not like they're even trying to blend in.
I think we're forgetting our history here. Peaceful protest only works if it seriously inconveniences as many people as possible for as long as necessary. Politely camping in a park without a permit doesn't really cut it. If they're using tear gas on you, it's a start. If they're using water cannon on you, you're getting somewhere. If they're setting dogs on you and hauling you away to county lockup by the busload, you're doing it right.
People forget exactly what happened during the Civil Rights movement in the United States. It's peaceful protest only on the protester's side. On the side of the so-called civil authorities, it's decidedly not peaceful, and rarely civil. And this has to go on for quite a long time. Literally years.
Occupy Wall Street accomplished nothing because none of that happened. These protests in Hong Kong will likely accomplish just as little. They're carefully avoiding inconveniencing anyone. Nothing happens if you do that. We demonstrated exactly that in the US. Hong Kong should learn from our mistakes. If they want to actually change things, they have to get obnoxious and get hauled away by those riot gear-equipped policemen. In droves. By the thousands. Or since we're talking about Chinese numbers here, by the tens of thousands. (It takes some serious effort to match per capita numbers in China.) Being careful not to interfere means you can be ignored, not just by authority, but by the man on the street as well. You must inconvenience people. You must interfere. You must do so as peacefully as possible, but you must do so.
Most recently, the US did it wrong. We in the US weren't willing to pay the price to get the oligarchs to back down. The populations of several Arab states did it right. Yeah, it hurts. Sorry, but that's what it takes. Are you in China ready?
Probably they mean it allows data to gzip directly from one phone to another. Nobody uses zip for network traffic.
It depends on bandwidth vs processing power.
Back in the 90s I used compression on networking due to having 56k bandwidth (yes thats 7 kB/s on LAN!). It actually increased file transfers quite a lot. However when switching to ethernet, bandwidth was no longer an issue and realtime compression actually slowed down file transfers. If the phones need to compress wifi data, then it would indicate really horrible bandwidth. I normally wouldn't think of that as an issue, but then again I don't put thousands of active wifi devices together in a small area.
I too am confused regarding the statement that they zip from one phone to another. I'm not even sure it is related to zip files or compression at all. Maybe it mean that it zaps from phone to phone multiple times until it reaches its destination, kind of like how lighting zaps around. That sentence is quite poorly written and would never have passed my quality control.
Imagine the reaction to our flying a B-52 with its bomb bay doors open low over a foreign city. Imagine how many people would be killed in the ensuing stampede, to say nothing of the air defense's reaction.
Hail Eris, full of mischief...
