Does your car lock up outside of cell coverage? I'm not suggesting removing the radios themselves, just the antennas. To the car, it will just always be out of range.

The antenna used for talking to the keys might cause trouble, but those are either inherently short range inductive systems or are receivable using a 20$ RTL SDR to verify it's not sending anything else.

Should be quite easy to remove any WiFi/cellular/satellite antennas from the car's computer. (Might be trace/chip antennas, so make sure to get those). If you're extra paranoid, get the GPS antenna too, so it can't simply record data indefinitely.

Might take a few hours to go through the car to make sure you get everything, but you won't be limited to super old cars.

Just add a delay that pads it out the execute time to 10 seconds. O(1) ez.

I reserve .elf for executables for other platforms, like microcontroller firmware.

You people realize that most crypto is even less private? Every transaction ever can be viewed by everyone, forever, by design.

Sure, a crypto wallet might not have your name on it when created, but good luck buying or selling any without giving away your identity.

Na let's keep timezones, there useful for humans who generally want time to mean something, but lets ditch daylight savings time, all it does is make scheduling a massive pain twice a year, and messes up everyone's sleep cycle. Without it, timezones would just be a fixed offset from another, minimizing trouble.

Don't forget the loss of productivity in the hours before the meeting, spent worrying about it.

Randall did the math on this one: https://what-if.xkcd.com/31/

He assumes 64 GB microsd cards, if you use 1 TB ones, you could send 16 times more.

Easiest and most secure way? Mail (or hand deliver) a flash drive. That's how they transfer data between super computers and data centers. (AWS even has dedicated trucks to do it)

Hot take, C is better then C++. It really just has one unique footgun, pointers, which can be avoided most of the time. C++ has lots of (smart)pointer related footguns, each with their own rules.

And more importantly, take investor's money. Most tech company are constantly losing money and depend a continuous flow of investor money.

Reddit lost 90 million dollars last year, that's why they did the IPO, so they could sell the problem to some sucker. Snapchat lost 1.3 billion last year, and would run quickly go bankrupt if people stopped investing.

As usual, the best way to get rich quick is by selling a get-rich-quick scheme.

Next DEFCON is in two months, can't wait to see them get absolutely pwned.
