<p>> The lack of hibernation with an encrypted system is an annoying problem, though.<p>I don't understand. Hibernation to an encrypted swap partition (and even to a swap file on an encrypted rootfs) works normally.<p>> Not buying hardware from certain vendors (Nvidia) helps improve your chances.<p>nVidia just works if you accept the proprietary driver. On the other hand, with AMD, you get fun like this: <a href="https://www.wezm.net/v2/posts/2020/linux-amdgpu-pixel-format/" rel="nofollow">https://www.wezm.net/v2/posts/2020/linux-amdgpu-pixel-format...</a>. Of course, if you don't need high GPU power, use Intel integrated GPU, which works the best.</p>

<p>> They killed at least 561 people<p>I don't know anything about this case, but "561 deaths have been reported in connection to" does not mean they were all indeed "caused by". They may have reports of anyone who died while using the device, from whatever cause like old age. Now they will investigate and hopefully conclude something.</p>

<p>> But in czech language word for Bohemia region is "Czechia" (there is no Bohemia).<p>No. Bohemia is Čechy, Czechia is Česko.<p>Yes, they are sometimes confused, and maybe people are unhappy with Česko because it's just too similar to Čechy. People from Moravia and Silesia feel underrepresented when someone mistakenly uses "Čechy" (Bohemia) for the entire Česko (Czechia; Bohemia+Moravia+Silesia).</p>

<p>"habanero eardrum" is actually less than 4 bytes -- let's say 12 bits for a common word (eardrum) + 16 bits for an uncommon word (habanero).<p>If it were 16 bytes, the other options from the same 16-bytes space would be, for example, "\xa3\x80W%\xa3\x82\xa1\xea\x10\xf9\x8b\x07'\xf93J" or "\xf0\xef\x9b\x8f[0\xe5\xb9,\x0b\xd4^\xb00\xed\x00" (chosen by a fair /dev/urandom roll).<p>If you want to convey 16 bytes using similar encoding, you need to use about 10 to 12 human words -- see for example Bitcoin wallet 12-word seed phrases or <a href="https://xkcd.com/936/" rel="nofollow">https://xkcd.com/936/</a> (xkcd correct horse battery staple).<p>For IPv6, if your addresses are not SLAAC, but DHCP or manually assigned, you can go with half of it - the "random" part is the 64bit network prefix.</p>

<p>Because the old algorithm only endangers the communication and the remote device (and this may even not be the case, as such an old device should not be exposed to the world), while the old client may compromise security of the local computer. (fortunately, bugs in SSH client are uncommon; with e.g. browsers it's a different story)<p>Of course a reasonable solutions would be to run it in some sandbox/VM.<p>Additionally, the old client will be difficult to use in a current OS because of library and general system incompatibility (Debian with openssh-client-ssh1 is a rare exception, and it's just a command-line ssh, not the library mentioned in <a href="https://news.ycombinator.com/item?id=38963372">https://news.ycombinator.com/item?id=38963372</a>).</p>

<p>> That screwdriver? It used to work when it was first invented and it will still work a thousand years from now.<p>Maybe it did not and will not -- old screwdriver is probably flat blade, now people use Philips or Pozidriv screws and in some time most will be Torx.<p>> That car? Keep it maintained and it will take you places for at least the better part of a century. That boat? We can keep boats floating forever.<p>The same: the fuel and oil is changing (maybe you will not even be able to source gasoline in 2050 if everyone migrated to electric vehicles), and specific spare parts are no longer manufactured.<p>I guess with large old boats also come expensive support contract - similar to paying someone for a super-long-term individual software support.<p>> Computers are one of the few, if not only, piece of tool that demands it be replaced every few years, and it probably hasn't even broken down yet which would merit a replacement.<p>Computers are also relatively new and quickly advancing in features, while the other examples you have mentioned were mostly "stable" for 100 years.</p>

<p>If I understand this correctly, the paper only shows a particular attack of complexity 2^102. Someone may find a different attack with much lower complexity. That's the usual way how cryptography gets broken -- people find better and better attacks, and suddenly the latest attack has low enough complexity to be practical.</p>
