    Building software from source

    Not to mention meson/ninja. Seems there's another new build system almost every other week.

    Personally, I stick with simple, hand crafted makefiles. I have held the belief for a while now that GNU autotools is a case of "cure is worse than the disease", primarily owing to the additional complexity it introduces.

    Unfortunately, you have to use whatever the upstream developers decided when you're building other folk's software.

    Building software from source

    Thanks for the heads-up. I've rewritten that section a bit.

    Building software from source

    You forgot to mention CMake. It's being used a lot now instead of configure.

    Systemd replaces plain text startup scripts with binary programs. It also provides a binary journal instead of plain text logs. This is very un-Unix-like, which is why a lot of people hate it to the point of obsession.

    One of the revolutionary things about the original UNIX was that the shell which the users used to launch commands was also used by the system to launch itself. That is no longer the case for Linux.

    How to read man pages

    Thank you, Hazel. This is a good start at shining a light on the man pages.

    In a word: "POSIX".

    That's what defines a UNIX. OS such as Solaris, HP-UX, AIX and macOS are certified UNIX.

    The 'BSDs, Illumos, MINIX3, etc are compliant for the most part.

    When it comes to Linux - much less so and depends largely on the distributions, really depends on how closely they adhere to LSB. Nowadays with most Linux distributions adopting systemd, they are certainly moving further away from this.

    What I discovered about pointers when I was learning C

    I must totally agree with GazL; absolutely brilliant blog post Hazel! That makes more sense than probably anything I've read about pointers and alike so far! I've even bookmarked this blog post for future reference! And it's the first blog I've ever rated here too, and I rated it five stars! Excellent work Hazel! You are very good at explaining things, you really are!

    Excellent work, well worth five stars! Nice one Hazel!!!

    What I discovered about pointers when I was learning C

    Excellent post, however one small error.

    Quote:
    It occupies four bytes just like any other long integer
    Pointers take 8 bytes on a 64bit platform. sizeof(long) also has a tendency to change depending on platform so that probably isn't the best way to describe the length.


    Another minor point, you can TRY and dereference a NULL pointer, unlike a void * the compiler won't throw an error, but the kernel will segfault your program at runtime when you try and access memory address 0. I suspect if you tried the same on DOS it would return a value.


    P.S. I also loved Turbo Pascal back in the day.

    Libraries: what they are, how they work, why you need them

    Hazel,

    Thank you for the article on libraries. Very informative and detailed.

    why were they called floppy disks
    The original ones were floppy inside and out. Then the 3 1/4 inch ones were in hard cases, but the disks inside were still floppy.

    Here's one: "Roll the tape."

    Yup! I have actually used a teletype as a computer terminal. When I started at BRE Library in 1977, they were using one.

    Forgot to add, the printer is a Brother HL-1210W monochrome laser printer.

    Thanks again

    Installing a Brother printer in 64-bit Linux

    Thank you for the use of the installer. I have one minor problem, when printing, I get a page that has an inverted comma printed evenly spaced down to the right of centre on the page. I have reinstalled the driver via the printer driver installer but the problem still exists.
    I am using Ubuntu 16.04.5 64 bit system. I have downloaded the .deb version of driver as I believe ubuntu is a derivative of Debian. Any suggestions would be more than welcome.

    Thank you,
    jacko777

    I actually found this extremely helpful. It is a simple breakdown of Unix concepts but I feel I now understand how Linux operates much more clearly. Well done and thank you for sharing .
