Anonymisation attack challenge – up to 5000 USD per attack
Working with sensitive personal data is difficult at best of times, and anonymising such data properly devilishly tricky.

At Aircloak we have built a software layer that dynamically anonymises the answers to SQL queries on the fly. We believe that the proof is in the pudding. Anyone can claim they are safely anonymising data, but very few understand what it actually entails. Deleting names or social security numbers is far from sufficient.

The challenge works pretty much like a normal bug bounty only that in this case you get paid for breaking the anonymisation rather than for finding security bugs. We pay up to 5000USD per successful attack.

To make it easier for you, and harder for us, you also get full access to the raw unanonymized datasets that we are claiming to protect as well as the ability to run as many queries as you want through our system.

If you are interested you can find more information here https://challenge.aircloak.com.

By way introduction, my name is Sebastian and I am the CTO at Aircloak. I am more than happy to answer any questions you might have whether they be about our system, our stack, or anything else that you might find interesting.

It boggles my mind every time I visit Seattle or San Francisco and I witness the struggle. The wealthiest people in the world responsible for developing, building and deploying the services that we all use everyday (and getting paid massive amounts for it), juxtaposed against the homeless and poverty stricken living directly next to them.
What is so important about that fact?

It is basic knowledge, that in a radio based system, like Wifi, Bluetooth, ZigBee, … you need to be near the source. That is called physics.

With some techniques you may passively can monitor radio waves, but for active attacks you will always need to be close by. That is called physics in general and specifically electromagnetic waves.
True, but if hostile agents could somehow sabotage essential things like power for a large enough geographical areas, bad things will happen. Long lasting bad things.

History shows that knowledge transfer is really, really hard. Humans are just not very good at it :(

(A similar story is told of the spread of the use of Feynman diagrams in physics - I’ve read that their spread was far slower than you’d expect given their utility: For whatever reason it wasn’t enough to be told that they were an incredibly useful tool by people you trusted - it was only when non users actually worked together on problems with Feynman diagram users, or were taught by Feynman diagram users directly that their use actually spread. Both of these transfer methods required physical proximity which restricted the use of Feynman diagrams to a small number of labs for a surprisingly long time.)

You're seeing this is smaller cities as well (San Diego and Portland come to mind). I'm curious on the data of homeless pop percentage-wise - as I think both of those cities would be much higher.

From an anecdotal perspective, I left San Diego for a year to travel and coming back now it's much, much worse than before. Tent cities are way bigger, the homeless population seems much more aggressive, and the small fact that we have a Hepatitis A outbreak due to there not being bathrooms for them[1].

While San Diego rent hasn't skyrockets like SF/Seattle, etc - the sentiment locally seems to be the huge increase is mostly due to other cities sending their tough cases here [2][3].

Seems like this should be one thing the government should be ready to handle, but it's only getting worse.

> I thought in the US you guys are more liberal when it comes to building highrises.

Even in a no-zoning "paradise" like Houston, short-term economics rule the roost. Approximate rule of thumb in the US I've heard is if a Single Family Residence is 1X cost per unit living area, a Multi-Family Residence (about 3-4 stories) is 3X, and a high-rise is 6X. Developers turn over inventory way faster at the 1X multiplier by selling to a bigger market. This is also confounded by American expectations of living space; they're not tempered much if at all by moving into apartments and high-rises, so costs go up.

US residential growth planning is all kinds of dumpster fire ugly, so these are by far not the only factors that contribute to why we don't see more high-rise developments in American cities. Just the tip of the seriously messed-up iceberg.
Do you guys think NSA or another country NSA knew, and exploited this? It's amazing how many years it took for this flaw to be found, despite being widely used. How many engineers looked at this over the years, thousands?

Most often, in general purpose programming, you don't need burden of managing memory manually. Things just go fine with a good runtime.

And that is what I think beginners should be introduced to - how to write code, how to frame algorithms in your mind and convert them into lucid code. Python does all of this wonderfully. It hides all of the internal details and exposes just the part that is needed for sometime writing a computer program for the first time in their life - simple statements which do simple things.

There is no need for a beginner to understand memory management at all. Trying to understand what is code or how algorithms work is more important to build that mental capacity IMO. Pardon me, but it does seem that just because you had to undergo the pain of trying to understand pointers, memory layout and allocations, you want everyone to go through the same experience as well.

There were several factors:

- This took place in Germany, where salaries don't vary to a very large extent. There are some outliers, but most people know they need to offer a certain amount of $$$ for talent.

- I did my research and assessed the current market. It was on par with my salary at that time.

- They made sure to communicate that there is no equity offered, which made me believe their salaries are adjusted accordingly.

- No, I didn't tell them I was turning down offers. But I did tell them that if they don't move faster, I'm going to accept another offer.

You want to maximize your surface area and protect your head. Let your body absorb as much of the impact as possible: Land almost horizontally, with your feet hitting first and your head hitting last. This way, you might only break every bone in your body instead of dying.

Basically they can see all your traffic and modify it. Your LAN becomes the Internet over an open AP and you don't know which servers you're connecting to.
Yeah, eventually I figured it out. The trick was to start an exponential growth of probes by focussing on self-replication... then things started unlocking and it went on from there...
The threat to such a tribe is any other group that feels they can take what that tribe has at a reasonable cost.

The problem is that figuring out who can take what from whom directly using force ends up with a lot of dead, and it ends up killing a lot of the farmers and artisans that ultimately are producing what you are fighting over.

The argument for federation or centralization is that you formalize the systems of stealing based on measures of force that involve less death and destruction than just having a battle every time your clan thinks it's stronger than the clan down the way.

When I was in university we made a project for the Statistics class: Measure the velocity of cars from bridges for cars going outside and inside a big city in Europe.

We controlled all big highways.

The result: Over 95% of the cars were going way faster than what the rules were and nothing wrong happens. That is, rules are wrong because politicians decide them and they are always extra cautious, so they are not responsible for accidents, and they make money out of fines.

I see a big problem if everybody follows the law every time, like robots do, because rules are so wrong in the first place.

One of the big things with robots is that you could have real feedback with real data measuring in the real world. You don't need to guess, just test in the real world and measure the consequences for example, of increasing the velocity.

You could also change the parameters on real time when you know there is ice or snow in the road... you don't need to have the same parameters when it is sunny in summer and in winter.

The big difference was that the damage was largely limted to those forums. There simply wasn't a critical mass of people worth influencing online, and mass culture lay elsewhere.

The hot jokes of the day turned up amongst Wall Street traders, probably spread by phone. Not Internet forums such as Reddit, 4chan, or Facebook. (You'd find occasional mentions of this in various news stories of the time.)

What's changed now is that the heart of media is online, and there are people who've realised this and are trying very hard to influence it. The period while different factions are sorting out what works, and various gatekeepers, including Google, Factbook, Twitter, and even, yes, our own Hacker News, sort out what their power and responsibility are, is going to be fairly chaotic (and has been). Much as in earlier periods of media transition: printing press, pamphlets, newspapers, magazines, radio, cinema, television, talk radio, cable.

Almost every period of new-media introduction has seen tremendous social and political upheaval. Many quite violent.

The issue isn't that the cars are worse drivers than humans. They're obviously going to be much better statistically. The article is just making the point that they're going to have to be programmed to break the rules just like humans do i.e. with speeding, stopping too often etc. If they are not programmed to break the rules, they will frustrate people and even cause accidents as humans try to interact with them. There's not always a good way to know that the car in front of you is being driven by a computer.
I rent an apartment with double brick walls everywhere. I cannot install cabling in the wall, or really anywhere it's not a severe trip hazard. For the most part, this is fine, because almost every device I own that requires internet access has wifi. (The few that don't, like my NAS, can live next to my networking equipment.)

Your suggestion would have meant that I couldn't connect my Playstation to the Internet, which is a little bit silly, especially given that my scenario is not an uncommon one.

You're right, though you're being a little rose-tinted about the situation. I think amazon.com shopping turned on redirects from HTTP to HTTPS last year sometime -- before that they would even redirect from HTTPS to HTTP. That means that until last year, in most instances, your coworkers or your fellow coffee shop customers could see which items you were considering buying online on Amazon. That's really, really bad!

Also, HTTPS doesn't protect domain names. If you're making TLS connections to (e.g.) a porn site over WiFi, the other people sharing your connection don't need to decrypt your traffic to know what you're doing.
