  • Great points.

    Regular solar cells with better efficiency are already are thing, even in a compact travel format or as a novelty part of some electric cars. Those are cheap to produce, but still aren’t practical at all, unless we’re talking about something like a 2m² solar panel to charge a phone in a somewhat reasonable time on a very sunny day in an off-grid situation.

    Using transparent solar cells additionally to regular ones in buildings instead of windows is pretty much the only reasonable application I can think of right now, but with a visible transmittance of 20% that’s kinda farfetched as well.


  • Das stimmt bei richtiger Verwendung schlichtweg nicht und es nützt niemandem, wenn man falsche Informationen herausposaunt. Wie auch im Artikel zu lesen, fand die timing attack auf üblichem Wege, gerade fürs deutsche Rechtssystem aber äußerst kontrovers statt:

    Zur finalen Identifikation verpflichtete das Amtsgericht Frankfurt am Main schließlich den Provider Telefónica, unter allen o2-Kundinnen und -Kunden herauszufinden, wer von ihnen sich zu einem der identifizierten Tor-Knoten verband.

    Bei einer Timing Attack werden, wie der Name schon sagt, Zugriffszeiten und möglichst viele (Meta-)Daten zu bestimmten Paketen statistisch abgeglichen. So kann man auch ohne direkten Zugriff auf die Daten bei ausreichender Datenlage feststellen, wer mit wem kommuniziert.

    Hier wurde schlichtweg jeder o2 Kunde in Deutschland erstmal pauschal überwacht, ob er nicht mit einem bestimmten Server Kontakt aufnimmt. Um dem entgegenzuwirken, kann man natürlich erst einmal über einen (no log) VPN Provider gehen, um gar nicht erst zugeordnet werden zu können.







  • Random guy with no affiliation to crypto and only a vague understanding of monero from another instance here, who saw the post on /all.

    Most people stumbling over posts like this probably see yet another shady cryptocurrency and aren’t interested or even actively dislike it, resulting in downvotes. Calling people “grudgeful bitfags” and “overly-sensitive leftist fediverse dwellers” probably doesn’t help all that much either, neither do comments that attribute a general disinterest to a “very successful psyop by the CIA to make crypto look like a scam”.



  • I have an understanding of the underlying concepts. I’m mostly interested in the war driving. War driving, at least in my understanding, implies that someone, a state agency in this case, physically went to the very specific location of the suspect, penetrated their (wireless) network and therefore executed a successful traffic correlation attack.

    I’m interested in how they got their suspects narrowed down that drastically in the first place. Traffic correlation attacks, at least in my experience, usually happen in a WAN context, not LAN, for example with the help of ISPs.

    Ehhh.

    Yeah, compared to a few years ago, it’s very much improved and a lot of games, especially those on Steam, run pretty good and in rare cases even better than on their native platform, Windows.

    But the pretty much broken state of VR support combined with some annoying bugs that are very hard to troubleshoot even for advanced users, the decision by most AAA and even some smaller studios to actively block Linux clients in multiplayer games via anti-cheat measures and the usual Linux fuckery of HDR, VRR (which hopefully will get better now that Wayland is getting there) and some NVIDIA fuckery (which is also getting better) leads to the following conclusions for me:

    1. Linux Gaming is improving.
    2. If all you play are some indie titles and/or single-player titles, you may be good.
    3. If you want to play in VR, most popular multiplayer titles and rely on features such as HDR and VRR, you’ll still need to dual boot into Windows.

    I’m very much looking forward to the day when I can fully banish Windows, at least from my private machines. I’m very tolerant towards debugging and living on the bleeding edge, if that is needed. But I don’t see the need for Windows for PC gaming to go away anytime soon for most users and, frankly, writing love letters to Linux Gaming without mentioning even some hurdles can, has and will take new Linux users by surprise and turn them off. Communicating transparently, so the user can make their own informed decisions, is a better strategy.
