  • Okay first of all this message is really nicely written to explain multi collision attacks! (I knew some stuff about hashing and collision attacks before but not about multi collision and why that would be really useful here.)

    However, I first thought they were looking for inputs which basically preserve a known state and then generating an alphabet with those kinds of blocks (basically have one for each symbol and up to n additional blocks to “reset” the state to the known value) because that could shrink the size of stored blocks by a lot (I’d imagine).

    But now I am wondering if that’s even possible currently (even with an algorithm as “broken” as MD5 has become now)?


  • Except you already have that update installed, the box is not checked and the entry is still respected, nobody could possibly tell you why because that’s not how it’s supposed to work and everyone else works as stated! And now you have to live with the knowledge that your system is in some unobserved quantum superposition with a critical fix in place which may stop working at any moment for any reason and nobody can tell you how you even managed to get into this situation…



  • This might be a bad place (i.e. post, the community is correct), but looking at the void has got me interested so I wanted to ask: What are the main advantages of using runit compared to systemd? Like I don’t want to know all the differences (of which there are apparently many since people complain about systemd being too “bloated”/spread out over different systems?)

    Also in all the “typical” discussion on systemd vs runit plenty of people talked about serious problems with runit and sometimes said something or other about process security? Is that substantiated in any way (as in “yeah technically during the boot process runit could be vulnerable to X if executing an unsafe script while systemd can’t do that because it does Y instead” or is it more like “yeah no, people just claim X when it’s not really possible or systemd also has the same problem, they just don’t talk about it”?)

    (Hopefully this doesn’t turn into yet another thread about people bashing each other over this choice since that usually leads to no information being really trustworthy unless one wades through tons of long posts external to the thread…)
