  • It should be “Pasteurize”, as it’s named after Louis Pasteur. And the specific process he invented dramatically increases the shelf life of milk using very high temperatures for a very short time… Without changing the milk texture or cooking it very much.

    So pasteurization is a process that sterilises did with heat. But I don’t think it works on meat.

    Yeah this stuff has to pass qual testing. Extreme high and low temperatures, vibration profiles, humidity and sea water exposure, probably shock loads, stricter EMI controls (compared to FCC), ESD exposure, explosive atmosphere testing, and so on and so on.





  • Compared to Windows NT, Linux is famous for using spare pages for cache, and reporting relatively high RAM usage, which is not directly related to the working sets used by processes. It also (I think NT also does this) pre-zeroes unused pages during idle CPU time, so they can be allocated to processes faster on demand.

    There’s probably no problem. And as the other commenter mentions, if you dig down into the reporting, you can figure out how much is actually going to processes.


  • Usually each distro decides which packages go in / and which in /usr based on how critical, more or less, a package is to the system. It’s often not very easy to configure these choices because it affects other distro decisions, including filesystem structure and paths, and boot sequence. Beware that “just the OS” on a typical distribution is usually a lot less functionality than you get with “just” Windows NT.

    There’s also /usr/local for packages you install on your own, apart from the distro package manager, and /opt, for closed source binary only packages or for anything else that doesn’t want to conform to the bin, lib, include, share schema.
