  • Again, not a military expert, but have you been living under a rock for several years and missed this whole Ukrainian “special military operation”?

    Russia’s hyped Kinzhal missiles, which promised to defeat air defence systems and be manoeverable at supersonic speeds are being shot down by 80’s era surface to air missiles. And I don’t think anyone has been in a position to assess China’s capabilities in the matter and I have no interest in discussing your beliefs.

    Edit: forgot to say this really has nothing to do with advanced lithography, anyways…


  • EUV is complex. And more so than the accomplishments you mentioned: nuclear weapons were cracked in the 1940’s, probe moon landings in the 50’s and space stations in the 70’s. All have since been reproduced by several nations in isolation. That is not the case of state of the art lithography. No single nation “owns” it because it truly is a multinational endeavor.

    (And actual hypersonic missiles haven’t made it to the battlefield, and 5G is about commoditization and standardization, by the ITU, an organ of the united nations, so I’m not sure exactly how that adds to your rhetoric)

    Way to put your ignorance on display.








  • I’m selfhosting a Matrix server and have all my Chats from other apps also bridged to there.

    Same here, but with XMPP in place of Matrix. For historical context, XMPP was invented about 25 years ago on the premise that people were already tired of having their instant messaging scattered over multiple protocols (rather than Signal, Telegram, WhatsApp, Discord, iMessage now, it was Yahoo, MSN, AIM, ICQ, … then), so bridging is very much front and center in the XMPP world. Over time, people also realized that bridging sucks in general (you either dumb down your client to the lowest common denominator which sucks for yourself, or your client isolates itself from the source protocol enough that it sucks for everyone else).
    To add insult to injury, most modern protocols also forbid, by their ToS, the use of alternative clients (which very much includes bridges), and to the best of my knowledge WhatsApp, Signal and Discord will eventually suspend your account on this basis.
    Matrix is still trying to carve a niche for itself in this space, and is failing IMO (judging by the quality/security of the bridges they have come-up with, and the recent libera.chat fiasco). I’d say that the situation in this regard in XMPP is only marginally better due to the fact that XMPP had a decade headstart to fail and try over, and I would not recommend using bridges on either of them if that can be avoided.

    It XMPP better for group VC?

    I’d say “it depends”. Fun fact, Matrix uses jitsi-meet under the hood (which is XMPP + a media transcoding/multicasting component that doubles as a relay), and jitsi-meet is my recommendation for this use-case: as long as the central server has good bandwidth, you can really scale up your VC to many attendees. On top of that, XMPP has support for peer-to-peer group VC, with the benefit that hosting is simpler, it doesn’t require any central component/relay (but the bandwidth cost is incurred on all participants and you won’t go beyond a handful of attendees that way).
