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.

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.

I was unfamiliar with misophonia so I went looking into it. I know it is a poorly studied issue, but I wasn’t able to find any peer reviewed research where children’s noises in general were used or reported as a trigger. I found lots of discussion forums, but that is anecdotal.

The reason I went digging is because the op describes all children’s noises, happy, sad, whatever, whereas what I read in the literature was very specific noises were reported as triggers. E.g, lip smacking, chewing, pen clicking, etc. In one study, they even used videos of children and dogs playing to help participants calm down and establish a baseline. https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0227118

While I’m admittedly ignorant, it seems OP may have a more general aversion to children than I would expect of misophonia given what I’ve read from medical sources.

I only mention this as a counter suggestion to help op avoid self diagnosing and maybe going down the wrong track.

I think counseling is warranted to help sort it out.

I would echo the recommendation for counseling. However, is this a larger issue or unique to children? Do you find yourself getting disproportionately angry at other sources of annoyances? Answering that question might help you know whether there is a larger need to address.

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

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.

Yup.

We do lots of things as a society because we’ve always done them that way, or it’s good enough, and not enough reason to go through the effort of changing everything including legal language, etc.

Happily, in this case I think ABV is about the best way we could have inherited, maybe only second to alcohol by weight in terms of consistency across temperature.

In the US, and I suspect other countries, the agency that regulates alcohol is different than the one that regulates food. In the US alcohol is regulated by the ATF and food by the FDA. Since it is the FDA rules that require nutritional labels and ingredients and not the ATF, most brands don’t list much.

Additionally, alcohol recipes are often considered trade secrets and closely held which might be why rules haven’t been introduced in many places.

Here is an article that talks a little more about different breweries and if they keep their ingredients secret or not.

https://i.stuff.co.nz/life-style/food-wine/89281511/why-doesnt-alcohol-doesnt-feature-nutritional-information-on-labels

Like I said, because the percent doesn’t change with the volume served. If you are an 1800s brewer you can calculate the ABV from samples, and subsequently sell kegs of various sizes, bottles, which in turn can be served in various amounts and the percent doesn’t change. And the industry never changed, nor the laws written. So it’s the way it is because that is how they used to do it and how laws were written and there hadn’t been a motivation for people to change that.
