Hey, sorry it took so long to see your question. Here is a paper (PDF) on the subject with diagrams.

https://www.research-collection.ethz.ch/bitstream/handle/20.500.11850/42365/eth-4572-01.pdf

The link is composed of two parts, the emitter and the receiver. The emitter captures the LF signal and up-converts it to 2.5 GHz. The obtained 2.5 GHz signal is then amplified and transmitted over the air. The receiver part of the link receives this signal and down-converts it to obtain the original LF signal. This LF signal is then amplified again and sent to a loop LF antenna which reproduces the signal that was emitted by the car in its integrity.

Edit: and here is a times article that covers the problem in one area. https://www.nytimes.com/2024/02/24/world/canada/toronto-car-theft-epidemic.html

Yeah. Shockingly people store things where it is convenient to have them. :) I’m glad I didn’t have a keyless system to with about.

I did read the article. I’m unfamiliar with the “hacking” tools or methods they mention given they use terms like emulator. I was simply sharing one wireless attack that is common in certain areas and why.

I think most of the wireless attacks aren’t trying to be so sophisticated. They target cars parked at home and use a relay attack that uses a repeater antenna to rebroadcast the signal from the car to the fob inside and vice versa, tricking the car into thinking the fob is nearby. Canada has seen a large spike in this kind of attack. Faraday pouches that you put the fob inside of at home mitigates the attack.

I’m not sure about what the article is referencing, which is probably a little more exotic, but relay attacks are very common against keyless cars. Keyless cars are constantly pinging for their matching fob. A relay attack just involves a repeater antenna held outside the car that repeats the signal between the car and the fob inside the house. Since many people leave the fob near the front of the house, it works and allows thieves to enter and start the car. Canada has has a big problem with car thieves using relay attacks to then drive cars into shipping containers and then sell them overseas.

With coffee all things heart palpations are possible. It took me about a year and a half between work and studies. Definitely not a day. 😀

That’s awesome, but no, they made something far more useful, lol. I’m glad to see projects like that though; it’s a lost art!

Years and years ago I built my own 16 bit computer from the nand gates up. ALU, etc, all built from scratch. Wrote the assembler, then wrote a compiler for a lightweight object oriented language. Built the OS, network stack, etc. At the end of the day I had a really neat, absolutely useless computer. The knowledge was what I wanted, not a usable computer.

Building something actually useful, and modern takes so much more work. I could never even make a dent in the hour, max, I have a day outside of work and family. Plus, I worked in technology for 25 years, ended as director of engineering before fully leaving tech behind and taking a leadership position.

I’ve done so much tech work. I’m ready to spend my down time in nature, and watching birds, and skiing.

Where I live they are mostly used in school zones and residential areas, and they only trigger when going 12+ miles over the limit. Seems pretty reasonable.

I’m sure it varies by area.

Where I live they install speed cameras in residential areas, school zones, and bus routes. They also only trigger when you are going 12 or more over the limit, and the highest speed limit I’ve seen with one these was 45mph, 35mph during school times. They also have an officer review and sign the citation, it is a flat fee, and no points. If needed, the officer who reviews will testify in court.

If someone is going 12+ over on school zones, school bus routes, and residential neighborhoods, then they deserve their fine.

The article says that steam showing a notice on snap installs that it isn’t an official package and to report errors to snap would be extreme. But that seems pretty reasonable to me, especially since the small package doesn’t include that in its own description. Is there any reason why that would be considered extreme, in the face of higher than normal error rates with the package, and lack of appropriate package description?

Thanks for the article, it was a fun read. I’ll have to go back and re-read the majority opinion because I do remember some interesting analysis on it even if I disagree with the outcome.

While not related from a legal standpoint, the use of iPhones and intermediate devices reminds me of a supreme Court case that I wrote a brief about. The crux of it was a steaming service that operated large arrays of micro antenna to pick up over the air content and offer it as streaming services to customers. They uniquely associated individual customers with streams from individual antenna so they could argue that they were not copying the material but merely transmitting it.

I forget the details, but ultimately I believe they lost. It was an interesting case.

Ants are the OG cooperative agent algorithms. Simulating ants use of pheromones to implement stigmergy path finding is a classic computer science algorithm.

Maybe it’s splitting hairs, but I recall the “chaste goddess of the hunt” and one of the three goddesses whom Aphrodite had no power. Additionally, goddess of healing, midwifery, and children. So I don’t know if the contemporary understanding of Ace matches that or not, as she is unaffected by love or lust.

So your comment made me go “lol, imagine buying a house in Russia.” Meaning my preconceptions were that most in Russia didn’t have the means to own a home.

But then I’m like, I don’t actually know that, let’s check it out.

According to this site home ownership in Russia is over 90%. So what you outlined is a real problem for people there, and changes some of my mental picture of Russian life.

The more you know!

For most people computers are just the same as cars. People want a car that will drive them from place to place, are easy to refuel, easy to operate, and can be taken to an expert for anything difficult or that requires specialized knowledge. Same for computers. Most people want a computer to navigate the web, install the apps they are used to and that their friends use, is easy to operate, and can be taken to an expert for any involved work.

Even the friendliest of Linux distro don’t check all those boxes. You cant get ready support from a repair shop, many of the apps are different or function differently, and it doesn’t receive all the same love and attention from major third party developers as Windows does.

Most people could learn to use Linux; it’s not that hard. Most people could learn to change their own oil. But for most people, it’s not worth it. For most people it’s not the journey, it’s the destination and cars and computers are just tools to get there.
