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.

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!

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.

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. 😂

Lol, yep. Twenty years give or take testing just about everything along the way. 😂

I’ve lived on East and West Coast in the US, visited most states and the places you mention in Canada, and I just moved from Washington to Maryland.

Realize that everything you listed as a preference is the same for millions of people. Lots of people like paddle boarding, nature, and the cities you are looking at, so those places are going to be expensive. Without knowing more about your acute needs to move I can only give general advice.

First, don’t move without a job lined up or at least a plan in place. Look at college towns including in more states than you listed. They are more liberal on average, and have a baked in supply of people looking for roommates. Even older grad students are looking for roommates and are often quiet.

After that, look for things to minimize costs like public transit. You say south of Maryland, but that covers a whole lot including places with pretty bad public transit.

When you do move make sure you have any vehicle titles or purchase documents as you will need them to get new titles and registration. Update your insurance policy with your new address. Make sure you have your birth certificate, social security cards, and photo id so you can get a place to live and get your new state id. Make sure you know what it costs to do all of that (likely hundreds on the title, registration, new id). Even more if you don’t have one of the necessary documents and you have to pay a notary to send a form to get a new title mailed to you.

Look at room mate apps or sites to potentially vet a low cost place you can move into more quickly than getting your own place and going through the credit checks and down payments for a lease.

And look at your credit to make sure you don’t move just to find that you won’t clear the checks they will perform.

Open a bank account at a bank or credit union with branches where you are moving to, or at least part of a no-fee ATM network. E.g., I can get cash from my credit union account without any fees from 7-11 and they are everywhere.

Make sure you have a few blank checks on your wallet for oddball expenses or deposits that don’t take cards or have fees to do so. Have a little cash as well.

Once you have a job planned, costs figured out, make a spreadsheet. MAKE A SPREADSHEET! You do not want to move across the country to find that you didn’t factor state income tax or vehicle registration costs and suddenly can’t make rent. Include all likely costs and see if your budget has some wiggle for miscalculations and other issues.

Make a spreadsheet of all the tasks you need to do. Keep track of them because the details of moving will screw you hard if you don’t mind them.

The more money you have while moving, the better you can solve problems. Hard truth for life in general.

If the above sounds overwhelming, then you need to plan all the more carefully.

Make sure you don’t make unrealistic assumptions about the culture of where you are moving and get taken advantage of our targeted for violence. Even in the most liberal places there are places and people unfriendly to LGBTQ people. Don’t be a victim.

Best of luck and happy to answer questions about specific cities, I’ve been to many.

I have to admit I used FreeBSD as my daily driver years ago. But I’ve also used everything else in the list at one point or another.

I use a terminal whenever I’m doing work that I want to automate, is the only way to do something such as certain parameters being cli only, or when using a GUI would require additional software I don’t otherwise want.

I play games and generally do rec time in a GUI, but I do all my git and docker work from the cli.

Right. Which gets us full circle, to never give investment advice, lol. That being said, at some point someone may sincerely look too you for guidance and you need to make a call as to whether you want to take that risk, what advice you give, and are you sure it is good advice.

I used to mentor student employees years ago, and when they wanted advice I always told them to max out workplace matches first, and then after that if they can save more, put it in tax advantaged savings programs that let you buy into indexed funds and never sell. In those cases you usually can’t even sell unless certain conditions are met and you sign disclosures, unlike most brokerages. Now, students you are giving them advice for the rest of there life and they likely don’t have $40k to panic sell/buy/sell to zero.
