It has been reported to Google (as a security bug) and to GrapheneOS as a comment in one of the very similar VPN leak issue on github. GrapheneOS has deleted my comment, probably because they assumed it was AI-generated or something, I&#x27

Do you have flea markets in DE? I'm pretty sure 10 kg of cables could be sold for more than €100 in a single day. Is it not common in DE?

Oh no, I wasn't, and that's definitely not my comfort zone. I mess with the printers and printing stack due to anger, not because I like it. It's bugs on bugs, with bugs chasing bugs! So little developers, so complex stack wi

I wrote an 'unlocking exploit' as a kernel module some years ago, and obfuscated it with a bit of self-modifying code. It could not make it work reliable. No matter which barries I set, I could not understand why is it not reliabl

Desktop computers work because Intel and AMD provide support to their chips to Windows and Linux, because these chips are used for desktop and servers, and these OS are what their customers use. Mobile chips are not used for desktop and ser

iPhone is top-of-the-line as well, because they control the whole software and the whole hardware (starting from basically all the chips). That's very rare in the industry. There are just a bunch of companies which afford to do the sam

The headphone jack is inside USB-C connector. You can use USB-C-to-3.5mm passive (!) cable to connect your 3.5mm headphones, or you can buy 3.5mm headphones with USB-C audio connection. There's no additional DAC involved, the analog au
