@eloy@hsnl.social Copyright isn't a bad thing. It is bad now as monopolies of companies license artists work to themselves, so they have to share less of the profit with the artists.

RE: https://mastodon.murkworks.net/@moira/116944488366439982 Smart TV's are mostly spy devices these days. Watching you, watching Netflix. From the thread, I see people suggesting that you either should run different operating system, don't buy this specific brand, or run these devices offline. While it is good that you've found a workaround, the general consumer does not know the difference between software and firmware, neither are they experts in network engineering. These company practices should be condemned, no matter if you can make it work. Furthermore, I see a lot of misconceptions of how Smart TV work (out of video scope). In short, TVs have a secure enclave with Widevine DRM crypto. Meaning you can only watch the latest series in the best quality for as long as the device is trusted. Disconnecting it from the web, or otherwise messing with it, may not have a positive effect on this trust.

Okay, LISTEN UP DO NOT BUY LG. Not ANYTHING LG. Not only are they actively spying on you, not only have they updated their TOS to include requiring you to NOTIFY GUESTS ABOUT WIRETAPPING LAW, on Windows they're pushing ADWARE through WINDOWS UPDATE along with their monitor drivers - including on OLD monitors. Gamers Nexus has all the deets: https://www.youtube.com/watch?v=Q9uefFYe6bM DO NOT BUY LG PRODUCTS. GN had a three-year-old monitor get an "update" that was adware. It wasn't even part of their investigation. It just happened to come in while they were investigating. DO NOT BUY LG PRODUCTS. #adware #spyware #surveillance #fascism #LG #FuckLG #DoNotBuy #boycott

@lokjo@mapstodon.space Clothes and many similar products don't come with information on their environmental costs. I'd be more willing to chose wisely if they came with this information. The 2.700 L seems a bit off for human consumption in 2.5 years. As drinking, maybe. At the water use in the Netherlands, 120L a day, not even a month.

I wish more of the effort of LLM was put towards making search better. As in when I search for 'high voltage DC power supply', it should understand I'm not looking for 'high precision AC power supply' or 'high power something'. From there we can have it learn component families, give equivalent suggestions, and near neighbors. And no, I don't want to 'chat' with an LLM assistant.

Sometimes I find security measures where I don't expect them, in this case in an email client. I knew it protected against receiving executables, but it also blocks large plain text files. While it makes sense, it's such an annoyance when you have a legitimate reason to send the data.

While it feels hacky, the solution seems to be 7z encryption. With the password in the email body for good measure.

I've had a variable energy contract for a while now. Even when I don't always use it as efficient, I like it over paying a flat fee. The energy market is a commodity, when more is produced and less is used, prices go down. Sometimes the prices go way in the red, which is quite exciting.
I've screengrabbed the with and without tax graphs, which go deep in the red for a few hours.

@mukmantheorigina It's not all bad, but it doesn't match my focus anymore. My niche, security of embedded systems, doesn't have all too many events. Either there are software security events, or electronics events. The combination is rare, strangely. The things which were new to me are high speed IR cameras, and presession GNSS which is (almost) unspoofable.

I'm at a tech event on embedded systems. While it is good to see trends, there does not seem to be much news. Better modules, higher precision measurements, but nothing shocking or revolutionary. The community has learned a few new words, including quantum, AI, and security, but can't yet define it. Quite adorable, but also frustrating.

For the hackerspaces open day I've visited @hermithive@mastodon.social in Nieuwegein. The space is in an old bank building, thus I want to share pictures of their vault. It's a Martens vault door from 1982.

@bas I'm unfamiliar with the product, and was curious. Usually you can find very much anything, be it at an inflated price. A quick search points to Jumbo. https://www.jumbo.com/producten/wereldkeukens,-kruiden,-pasta-en-rijst/aziatische-keuken/indiase-keuken/the-spice-tailor/

@revspace Depends on your target group. Do you want humans or LLMs to show up for the event?

@eloy@hsnl.social Het kan nog beter, je zou er een wiki van kunnen maken die makkelijk aan te updaten is en te delen met criminele vriendjes. Maak een datalek data leuk.

@krijnsoeteman @schellevis Mogelijk komt dat meer door het begrijpbaar op te schrijven waardoor het minder exact is. Als in, gegevens (records/platte tekst) waaronder (document nummers van) paspoorten en rijbewijzen. Bij een nieuw abonnement kwam een mannetje met een mobiele scanner op bezoek. Deze scanners checken de echtheid van documenten, maar slaan verder geen kopie op, afaik.

@KatyElphinstone@mas.to I don't believe I lack creativity. As an engineer with autism, I'm able to combine solutions in unusual ways. I can get stuck in the iterating, where a solution is rarely good enough. (And believing my solutions to be trivial once they are 'invented')

@geekmomprojects@mastodon.social

I've received one of your Bendy SAO from a friend at @bitlair@hsnl.social. My addition are a few 3D printed bits and Dyneema fishing line to make it move.

Thanks for making this add-on available, it's a rather silly project :)
