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.

No one said cheap alcohol except you. I brew beer, discuss brewing beer, and very much appreciate the culture and history of brewing. I also enjoy reading about classic cocktails, and occasionally having some. I’ve read entire books about the history of distilling, the origin of terms like the angels share, etc.

The opinion posed wasn’t that we should get rid of cheap alcohol, but that all alcohol should be banned everywhere.

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.

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!

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’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!
