  • Energy density has been the number one most important factor since humans started using metal. Wood is good enough to smelt bronze, and with some refinement can get your iron, but not good enough for steel. Steel requires coal, and with some refinement steel is what our world is built on.

    Fossil fuels allow cars, planes and more efficient trains and boats. Unless we somehow start utilizing uranium and transuranics electric airplanes are for grifters. Uranium and it’s derivatives are the only thing we have harnessed that even approaches the energy density of fossil fuels.


  • I’m a network engineer and I run ipv6 natively in all of our datacenters. There are even a handful of end systems that have ipv6 native networking stacks with ipv4 sockets for our non-ipv6 compatible applications. IPv6 issues are basically self-inflicted at this point by companies that see their IT systems as cost centers, or by basilisk directors who’s knowledge stopped in the 90’s.

    Seems novel. But from a security aspect, if OpenSSH has security vulnerability that allows an unauthenticated user to login, via whatever means, once you are in the system as a non-privileged user, you are now free to use the same vulnerability to get root.

    Basically this exercise is like using two locks that have the same key to open them. If the same key opens them, then a weakness in one, is now a weakness in the other so why bother with two identical locks?

    Gaming laptops have always been an extremely expensive but less capable desktop. Their portability is laughable, and pointless. Their battery life is non-existent, and if you can’t easilly move them, and you also have to plug them in all the time, then what does a laptop give you?

    Not to mention their bad keyboards, bad speakers, a touchpad? and compromised screen. Not only should they be left behind, they shouldn’t have existed in the first place.

    hahaah. Ok sure you win. Linux TTY’s are absolutely not terminals. Sure they are called terminals, they are for all intents and purposes modern-day terminals with a long and storied history that directly links them to terminals from the 70’s but since they aren’t a physical piece of hardware that electro-mechanically connects to a mainframe, obviously they aren’t really terminals and they should be be called something else.
