    hpr1666 :: Bare Metal Programming on the Raspberry Pi (Part 3)

    This episode, embedded programming, ARM co-processors and the ARM memory management unit.

    This is the third episode in a series on bare metal programming on the Raspberry Pi. This episode rounds out my initial stab at doing a series on RPI embedded programming based on my summer vacation project. This episode discusses how to write code with an eye towards using it in an embedded environment. It continues with a discussion of how coprocessors fit into the ARM architecture. It also describes how to manage coprocessors programatically in a very hackerish way using self-modifying code. Finally, the episode describes how to enable the virtual memory subsystem in the ARM as well as the cache. It includes some performance measurements of my code both with and without the cache enabled.

    Here is some of the source material that I reference in this episode. See the previous episode show notes for information on how to get your own bare metal Raspberry Pi setup up and running.

    • A fantastic book on low level computer mathematics. I find it a joy to read. I cannot recommend it highly enough. It belongs on anyone's shelf next to Knuth and other "programming bibles".

    We take a look at one of the most powerful, but somewhat frightening, features of modern spreadsheets. But knowing the basics of pivot tables should make them a bit less frightening to the newcomer.

    Life and Times of a Geek - part 1

    I really liked David Whitman's idea of doing a show on his birthday http://hackerpublicradio.org/eps.php?id=1547, so I'm borrowing the idea.

    This show is being released on my 65th birthday, and I decided to use this opportunity to tell you about my long experience with computational devices as part of the series "How I Found Linux". Thinking about what I want to cover, I realise that it might be quite a lot, so I'm organising the shows into a collection of short episodes.

    I have been thinking about doing this for a while. Up until now I was concerned that it would be a bit self-indulgent, but I have been advised to just go ahead and do it. I hope you find the shows interesting.

    hpr1660 :: Trying out Slackware

    Slackware-newbie Beni is talking to long time Slackware user mcnalu

    mcnalu wrote a article about Slackware in Linux Voice, Issue 6.

    tux smokes a pipe with the hpr logo

    http://www.linuxvoice.com/issue-6/

    Beni read this article which lead to him trying out Slackware and being very impressed by its simplicity.

    That's why he asked mcnalu to do a HPR episode about Slackware, which is probably the oldest Linux Distro that's still around and whose developer follows a no-nonsense strategy and is very conservative when it comes switching to new stuff that comes up in the Linux world (like PAM or systemd)

    The distro is one of the if not the most Unix-like Linux distro. It uses a BSD style init system instead of widely used sysvinit.

    Beni and mcnalu talk about the installation process, finding dokumentation and why the website is outdated.

    Further they discuss the package manager and what it means that it doesn't resolve dependencies. They also explain why this isn't necessariliy a bad thing and where to find binary packages.

    In the end they talk about where the Slackware community meets and who is in charge of Slackware.

    http://www.slackware.com/ https://en.wikipedia.org/wiki/Slackware

    Slackware documentation isn't as good the BSDs dokumentation or the Arch Wiki. But it's definitely getting better

    http://docs.slackware.com/

    and there is also 'Slackware essentials', a book that's also available online:

    http://www.slackware.com/book/

    The Slackware forum on Linux Questions is pretty much the official Slackware forum: http://www.linuxquestions.org/questions/slackware-14/

    mcnalu announced his Article in the Linux Questions forum: http://www.linuxquestions.org/questions/slackware-14/linux-voice-issue-6-a-4175513762/

    To support the development of Slackware you could buy yourself a Christmas present from the Slackware store:

    Command Line Tips: using CTRL + Left / Right arrow will allow you to move through a long command word by word instead of moving through each letter. makes making adjustments to a long command much quicker use the "cd -" to move back and forth between previous directories. cd into a directory, then cd into a different on. Now do "cd -" and you will be back to the first directory.
