There was a limited time window in the early 2000s where many cars used only obfuscated access or a cryptographically insecure PIN code for key enrollment, but most modern cars use an attempt at cryptographic security with a centralized server.
If you want to see what's possible with modern cars, keywords like "VVDI" or "Abrites" and "All Keys Lost" will show you what aftermarket tools are capable of. Generally speaking, the capabilities in these tools are roughly equivalent to those the most sophisticated criminals have, as they're usually just stealing the techniques from one another in a big circle.
The level of security varies heavily from manufacturer to manufacturer.
For example, most modern VW cars require using an ECU exploit (which depending on the specific ECU, almost always requires physically removing the control unit and sometimes requires opening it) to extract encryption key data (CS/MAC) or physical extraction of the instrument cluster EEPROM.
However other manufacturers like Toyota seem to be more vulnerable to other exploits (I only research VW for the most part, so I frankly have no idea what's going on here), including a bizarre process which seems to require disassembling the steering column and unplugging a connector.
I'd love to have an open source CNC machine to design joinery with http://ma-la.com/tsugite.html
Ideally a whole house and most of the furniture...
If anyone has any ideas on how to accelerate build times of open hardware, that's something I'm trying to solve. Creating high quality instructionals is a huge amount of work and I think instructionals should be automatically generated by computer vision and have interactable elements, ideally AR, but even just highlighting wiring diagrams on hovering would be hugely helpful. Even if things are well documented, replication is still insanely pyrrhic without economy of scale or universal fabrication. It's time consuming because it's hard to replicate knowledge/tool environments quickly.
You should post a Show HN when it's open for people try out. See https://news.ycombinator.com/showhn.html and https://news.ycombinator.com/item?id=22336638. Email me at hn@ycombinator.com with a draft text and I'll look it over for you beforehand. Same offer goes for anyone, just please don't expect a quick reply- that depends on the wild swings of the HN inbox. You can also see how we advise YC startups to do this at https://news.ycombinator.com/yli.html - the logistical parts are YC-only but the communication parts apply to everybody.
THis guy is my favorite professor from my school. He has posted online lectures because of COVID and decided to put it up on his youtube channel so people can watch.
back in the day this course had like 25 official seats but like 40 people would show up every day to "unofficially" audit the course.
For anyone who hasn't yet had the pleasure, Scott's (fiction) book Unsong is magnificent. It's one of the best books I read last year, and I read constantly.
“I AM BUSY. I AM TRYING TO FIX CONTINENTAL DRIFT.”
“I…didn’t know it was broken.”
Uriel’s face became more animated, his speech faster.
“IT HAS BEEN BROKEN FOR FIVE WEEKS AND FIVE DAYS. I THINK IT BROKE WHEN I RELOADED NEW ZEALAND FROM A BACKUP COPY, BUT I DO NOT KNOW WHY. MY SYNCHRONIZATION WAS IMPECCABLE AND THE CHANGE PROPAGATED SIMULTANEOUSLY ACROSS ALL SEPHIROT. I THINK SOMEBODY BOILED A GOAT IN ITS MOTHER’S MILK. IT IS ALWAYS THAT. I KEEP TELLING PEOPLE NOT TO DO IT, BUT NOBODY LISTENS.”
If the supplies required for Tesla workers to safely perform their jobs aren’t available, maybe they shouldn’t be reopening their factories. All this reopening is at the expense of the employees being prematurely forced to resume work. From what I’ve seen, those that are pushing for reopening aren’t the ones that are likely to actually contract the virus at their job.
