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.

So first there is a difference between reduction of meat products and an elimination. Having people consume less meat is good and helpful even if they don’t cut it out completely.

Second, as a vegetarian, I don’t understand what you mean by producing a bunch of monocultures. Do you think vegans just sit around all day eating avocados? I eat very little dairy or egg, and my diet consists largely of beans, rice, chilli, bread, stir fry, tofu, peanuts/legumes, veggies, baked potatoes, sandwiches, etc. I eat a large variety of staple goods cooked into a variety of dishes from around the world, and classic American fare, just without meat. Avocados and other resource intensive crops like almonds are a minority of my diet by a large margin. Things like beyond meat is also an infrequent treat.

Edit: here’s a decent article. https://www.nytimes.com/article/plant-based-diet.html

Generally speaking, a plant-based diet consists largely of vegetables, fruit, beans, legumes, grains and nuts, with little or no meat, dairy or fish.

Yet another major study has recently been published, showing that eating a plant-based diet is significantly better for the environment than eating a meat-based diet.

The research, conducted by Oxford University, found that people who follow a meat-free diet are responsible for 75 percent less in greenhouse gas emissions than those who eat meat every day, and that following a low-meat, vegetarian or pescatarian diet is proportionally less detrimental to land, water and biodiversity than a meat-heavy diet.

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!

In that context it reads like the bill is more intended to shield people from charges who end up in altercations after telling people to leave.

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.

The one thing I’ll say as someone with years of management and leadership experience, is that these posts always ignore what the people want. I’ve coached many employees, and I always start with asking what they want to achieve. Some people are really career focused and want to climb the ladder. Others are happy putting in their 40 hours and making modest progression from entry to junior, and maybe senior eventually.

If someone wants to climb the ladder, or became an industry expert, or make the very top of the range, then yes, that’s going to involve some grind. But some people just want to have a comfortable life while doing their fair share during their 40 hours a week. And there is nothing wrong with either approach.

Telling all young people to grind 80 hours a week, ignoring what they want to achieve, or if they are even likely to succeed in their goal, is management malpractice. But I digress.

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

I look at the long arc of history and see that progress is not monotonic (always increasing or decreasing). We are experiencing setbacks to overcoming our challenges, as have those who came before us. But while we can read about years passing in a paragraph in a history book, we have to live and experience those years. And with all the challenges comes new technology and drive and awareness to solve problems. As unfortunate as it is trouble breeds innovation and commitment to change far better than comfort and easy times.

In that case, never mix business and family. 😂
