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.

There is not a single reason for any human to get access to alcohol.

But there is. Because people enjoy it. Because it is a carrier of culture, tradition, and history. There are many things that people do that have risks, negative health effects, etc. Should all of that be illegal? Rock climbers sometimes need rescue, whose cost is often born by the public. Cell phones cause distracted driving. Processed foods make it easier for people to overeat, become obese, die, and create costs for society along the way.

Your premise is that there isn’t some transactional, functional value of alcohol. But people aren’t robots and we get value from the emotion and experience of things.

Tax alcohol to cover negative externalities, enforce drunk driving laws, force disclaimers about the health impact, and let people make informed, but free, choices.

Good unpopular opinion though. Good discussion! Have a great day!

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.

I need to start using old batteries in my bathroom scale.

Some suggestions, either online or local;

Bookclubs
Walking groups
Chess, board games, table top
Theater groups (meetup groups to go to the theater as a group)
Escape room group meetups.

Depending on if you are in a city or a smaller town the locals options will vary. I’d look at meetups site and browse local activities. For most any activity you will find a range of ages, but some will skew more one way than another.

Best of luck!

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.

The TPM requirement, I agree seemed a bit much without enough warning to the hardware industry. It’s all the more puzzling because it is trivial to install with the TPM requirement disabled.

That being said, I’ve done tech support forever ago, and I still help my in-laws with technology, and I get it. Microsoft is pushing improvements for people who otherwise wouldn’t do anything for their security or even continuity of operations. Windows hello, for all my gripes with it, gives people a password reset and recovery option for their OS.

But to your point again, I think the TPM requirement should have been phased in more slowly.

Have a great night!

All the way back to Windows NT Microsoft sold extended support for business customers while security updates stopped to the home customer. For the past several major releases Microsoft has a five year mainstream release, 5 year extended support, and then a paid extended period for business. That was the same for Windows 7 as far as I can tell. Honestly, it seems like selling individual esu’s is giving the individual more options. I mean, I don’t get it personally. But if I had some reason to absolutely stay on Windows 10, I would appreciate the option to pay for security updates for years 11, 12, 13+ of the OS.

That being said, I’m not sure who these people are that both love Windows 10 to the point of staying with it past regular support, loath Windows 11, and don’t want to give Linux a try. Like, barring weird technical requirements, that’s a Venn diagram that I just can’t square.

And I’m aware of the shenanigans Windows 11 pulls, but also know the savvy or opinionated user can disable most anything undesirable that makes it different from Windows 10. It’s a bit clicky, but you can disable or hide most things. And if it’s the principle of the thing… Get thee to a nixery!

That’s right, I suggested couples massage not because it is the epitome of travel but because it’s something he could go do immediately that doesn’t require booking months ago with a time machine, and it’s relaxing. Dudes obviously stressed.

It’s really amusing seeing some folks (not you) trip over themselves to gatekeep what travel is to someone like me whose climbed extensively around the world. Like yeah, trekking the remote corners of the world is awesome, but that doesn’t make getting a nice massage with your wife a bad time, lol. Not everything in life needs to be a purist expression of a hobby or passion.
