zhongjiewu··on China Sacrifices a Province to Save the World From Coronavirus
Correction: not arrest. They were summoned and given written warnings. China is quarantine one Province. Travel between other provinces are still not affected. International travel bans is basically as strict as traveling out of Hubei province, stricter than average travel restrictions in China.

> Supplies and doctors still came in after lock down. You mean the government get doctors from other cities to Wuhan because they are not needed, regardless if Wuhan is in medical shortage? This is a weird logic that I cannot agree. IMO, mobilizing doctors from hundreds of miles away, which costs a lot money and management effort, is exactly an attempt to solve the shortage issue. There are various video materials showing super crowded hospitals in Wuhan and other Hubei cities. It is also consistent with building not one, but two temporary hospitals with thousands of workers at much pricier cost.

Based on the activity data from TV news, fever related medical visit stays in single digit nationwide. If lock down are not announced and enforced, people in Hunan that are richer will flood to other cities such as Shanghai and Beijing for better medical services, as this happens from several news reports. People would choose to travel since their immediate action will not cause medical shortage elsewhere before they are handled. The idea of seeking medical help elsewhere will make matters worse is correct, but it is a macro level insight and will not change these people's mind to grasp these resources before they are gone.

It is not deniable that without a lockdown, people in Hubei province will on average get medical help in the short run and everybody else is much worse off. This is why it's not a sacrifice.

Honestly I think it is hard job to get an accurate reporting giving the scale of the problem. We are talking about a single digit accuracy at the scale of 10k+. Even in H1N1 outbreaks, the medical visits and death tolls in the US was estimated with a wide band. That being said, the death of un-confirmed patients could be intentionally ignored to make the problem look not so big. But this is not a unique thing to authoritarian governments.

It is not entirely true. This sacrifice entails two things. On one side, without a lockdown, people in Human can seek medical help in other cities and provinces when they get sick. After a lockdown, local medical resources are in severe shortage hence higher death rate. On the other side, it limits the spread of the disease for the good of other provinces and hence the rest of the world. If this isn't sacrifice, I'm not sure what sacrifice is.

Ironically, there are aircraft carriers moving around the oceans forcing some countries regarding some agenda.

I agree, if there is a region with the labor force and good policy for investment plus infra and a few other things. Vietnam is a close enough option, but other options are not abundant, so more than just a few years would be a plausible answer for me.
zhongjiewu··on Show HN: Polarr.co, a WebGL photo editor
Do you use a three level hiearchy on the image? I assume you guys first down sample to full resolution preview(like 600x400) and a low resolution preview. When editing, filter applys on the low resolution preview and then full resolution preview (1.5second latency). When exporting, you apply all the filters on the original image. Is it the case?

I've been following the development and progress of you guys for the past month (after I saw Tom speak at the Google event) - glad to see the funding has come in. I became very intrigued after that Bitcoin conference, and thank you guys to helping me learn about the industry.

Wish you all best of luck on journey.

This is exactly how it works. And a lot of apps use this JS bridging technic to make their app easy to maintain. Dirty hack becomes technical debt

You would never be able to install an app without user click "install" etc.

This one uses Javascript Bridge vulnerability to execute high privilege code in your Android. The attack code is javascript to be interpreted to Java calls in Android.

You wouldn't be able to do that in iPhone though.

I wouldn't comment on their AntiVirus stuff but I think the vulnerability in the Bing App is real.

Sounds like very dangerous attack and not very difficult to implement.

DNS hijacking:

1. Quicker DNS response than router to pollute the Android's DNS

2. Rouge AP that pretend to be common free public wifi like "att", "starbucks", "cablewifi" or "Free Public WiFi"

3. De-authenticate valid AP connections and force user to try rouge WIFI

MITM attack: 1. ARP spoofing
