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!

I gave my kid a BB gun, but it stays in a safe. I also gave my son a pocket knife for camping that stays in my night stand unless we are camping.

You can give something to a kid without letting them have unsupervised access. I gave my kids steam decks, but limit their screen time.

I agree the original comment lacked specificity. You could gift a gun in a responsible or irresponsible way, and I’ve seen both.

Edit: and the comment about gifting a rifle also mentioned that in their personal situation they had to have a parent to use it.

There’s a huge difference between giving a child unrestricted access to a firearm, and taking them sport shooting in a controlled environment. I’ve helped with beginner shooting courses for kids in scouts. There is an adult with each kid, one round loaded at a time, etc. You can similarly control the environment hunting by using blinds, etc, where you oversee the use of the firearm, loading of round etc.

I’m not big into shooting, but from a safety perspective there are ways to hunt and sport shoot with kids in a very controlled way.

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.

Minimum wage is an absolute measure: a fixed amount not pegged to inflation. Taxes are a percentage, a relative value that adapts to inflation.

I’m all for a relative measure for the minimum wage.

Also, in this scenario the people would be left with $1,620,000 after selling their house, which hardly leaves them without options. I get that they want to stay in that same neighborhood. But the problem they are facing is an enviable one for many less fortunate people.

Yeah. I’m not hating on these people, but they would have $1.4 million in taxable income, and 37% would be owed as taxes, leading them around 900k. If they planned it over a few years they could actually avoid some of that.

So I don’t know their situation, but walking away with $882k doesn’t leave you without options.

Edit: I forgot that you only pay the normal income rate on assets held for a short period, so they would have $1,620,000 after taxes.

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 crime stats and stories in this case are so bad they’d be comical if it didn’t represent desperate people.

Since 2019, police have logged 1,335 incidents in the vicinity of the restaurant on Oakport Street — more than any other location in Oakland, the newspaper reported.

That number includes nine robberies, two commercial burglaries, four domestic violence incidents and 1,174 car break-ins, according to Oakland police data shared with the Chronicle.

I saw elsewhere that a guy got robbed there, came back to do a news interview, and got robbed again. The crime stats mean basically a crime a day at that location.

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.

My Costco photo is 20 years old and looks nothing like me anymore, but when I asked for a new photo they said no. So obviously they aren’t looking closely at pictures.

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.

I’ll give you some general advice and am happy to answer any follow up questions you might have.

Upfront, I recommend getting a laptop from a well known vendor running Windows. If you aren’t looking to go on a technology learning expedition, just need something that will work, and will have a warranty and a support line if things go wrong, you can’t beat a vendor. Dell is probably where I would look, but Microsoft surface, and Thinkpad’s are also good.

Going with Windows from a vendor supplied laptop will maximize the amount of support you have and the number of things that just work.

If you are looking for more of a technology project, I’d need to know more about what your tolerance is for fiddling with technology or your computer not working.

As for CAD, as others said, check the recommended software specs and match your computer to them. Make sure you give yourself plenty of fast storage like m.2.

For browsers, I use Firefox. I’d recommend Firefox as being a good balance between privacy and just working with plugin support. But chrome and other chromium based browsers like edge also just work.

Consider getting a Microsoft 365 personal or family account. For $100/year you get cloud storage, computer backups, and the local and online office suite, and it all integrates well into Windows.

If any of the above assumptions are wrong, I’m happy to update recommendations.

Finally, how do you learn to fish? It takes time to come up to speed on things, so slowly learning, finding neutral review sites like maybe Tom’s hardware, and doing your own testing.

Lots of people will give you opinionated advice, so don’t be afraid to be skeptical. Think about what’s important to you, whether that be just working, or privacy, or availability of support materials.

I don’t disagree that comment OP could have phrased it better and come across as less judgey. And I think that of someone like you left a well worded reply to the effect that it would be very fair feedback.

At the same time I feel like some of the comments she has gotten are living down to the less generous version of her statements. If that makes sense. It also sort of feels like people wallpapering over the underlying reason that many women look for social media participation, which is as a way to vet for safety reasons.

But I agree, it’s not good to typecast and overgeneralize, and a better suggestion to the post OP might be that some women look for social media accounts for safety reasons, if that is part of your social issues mentioned.

But I digress. Have a great day!
