  • Within section 2.1 choose only one subsection to follow. Those are all alternative bootloader options.

    The bootloader subsection chosen in 2.1 on this page should match what is done in Configuring the Bootloader. The default path on that page is GRUB, which does not require any systemd components.

    If following the GRUB path, follow instructions in 2.1.1 and skip the rest of 2.1. This is not at all clear in the handbook.

    I believe that sys-kernel/installkernel is a utility script internal to the Gentoo project that can be configured to work with various bootloader solutions, including (optionally) systemd, and that is what this section 2.1 is talking about.

    This appears to be an out of order dependency in the handbook




  • No. For several reasons.

    Fortran is older than Basic and C. In fact, Fortran is more or less the first high level programming language. The first Fortran compilers date to the early 1950s.

    Fortran was created mainly for the purpose of linear algebra: operations with (giant) matrices. Linear algebra is used to compute approximate solutions to ordinary and partial differential equations, and this is a major part of what people needed computers for (and still do).

    Programming concepts like subroutines, functions, if statements with blocks and else clauses… All of those were not in original Fortran because no one had thought of them. These things entered Fortran over time as they became popular, and goto slowly became less popular. Syntax from the punch card era was replaced in Fortran 90, but it is still available as an option for compatibility purposes.

    Structurally, I prefer to describe Fortran as like C, but with better built-in arrays, and no built-in general purpose pointers. Not having the pointers allows the compiler to do certain optimizations that C can’t. But C is the better systems language, because the pointers let you naturally express all kinds of data structures besides arrays.









  • Kill -9 is a command on Unix and Linux to send signal 9 (SIGKILL) to a process. That’s the version of kill that is the most reliable and has immediate effect.

    Taskkill is a Windows command line program. I believe that taskkill /f uses the TerminateProcess() API. This is more forceful than the End Task button on the Task Manager. There is a different End Process button on the Task Manager that does use TerminateProcess().





  • The Linux software you can get as a regular user from your typical Linux distributions is absolutely not any more secure on average than your typical Windows software.

    I say this as someone who writes application programs on both systems.

    I think it’s really debatable whether the Linux kernel is really any more secure than the Windows NT kernel. Linux advocates have pushed the “many eyes, shallow bugs” line for a long time, but high profile lapses seem to really have put the lie to that.
