This is a HowTo for setting up ikiwiki with Merecat httpd. First install ikiwiki $ sudo apt install ikiwiki libcgi-session-perl libcgi-formbuilder-perl Follow the steps to setup a new Wiki or Blog. In this example we set up a wiki in our ~/public_html: $ ikiwiki --setup /etc/ikiwiki/auto.setup ... Successfully set up wiki: url: http://localhost/~jocke/wiki srcdir: ~/wiki destdir: ~/public_html/wiki repository: ~/wiki.git To modify settings, edit ~/home.setup and then run: $ ikiwiki --setup ~/home.

Having worked with Linux for the last 20 years, and embedded for more than ten of them, I’ve become quite a fan of virtualization in general and Qemu in particular.

Qemu is a fantastic little tool, created by the Open Source superhero Fabrice Bellard. It can be used to verify an embedded system without having to deal with the problems of actual HW until you really have to. Don’t get me wrong, HW excites me like any other nerd, but if the HW is new and shaky it can be quite a pain to develop higher level functions.

My holy grail is to have a 100% complete and accurate virtualization target per architecture to test my various software projects on. That’s why I created TroglOS.

The last game I ever played was Castle Wolfenstein 3D, released in 1992 for MS-DOS, made by the now legendary id Software. OK, admittedly I’ve played other games since then, but I’ve never again been so manic about a game since Wolfenstein.

This post is about how to build, install and set up Wolfenstein 3D on a Raspberry Pi running RetroPie … on a Picade :-)

This is a quick writeup of how to get the Trust Bluetooth 4.0 adapter (dongle) working in Linux, Ubuntu 16.04.

Ever since my first stumbling steps with Linux back in ‘96, I’ve been learning about UNIX. The first obvious lesson was to not use the root account. Since then I’ve been using a combination of sudo command and suid root binaries to get the job done. For the last ten years, however, I’ve been meaning to learn about Linux capabilities(7) and thanks to a colleague of mine I now have :) [Read More]

For some odd reason, today was the day when I woke up and continued working on libICMP. It’s now almost seven years since I first adopted Tim Lawless’ public domain version, and today I picked up where I left off and started refactoring and cleaning up. Example: #include "icmp/icmp.h" int main(int argc, char *argv[]) { char *host = "localhost"; struct libicmp *obj; if (argc >= 2) host = argv[1]; if (! [Read More]

This post is about my adoption, refactor, and rebranding of thttpd as Merecat.

I code for recreation as well as work. Most of the time I tinker around with my various projects simply to learn and sometimes these little projects turn into something useful for other people as well, which is great!

When I recently had to migrate my personal blog, FTP, and GIT server, I set out to run everything from an old RasPi2. This put my private life in just about the same niche as my work life, embedded. On a resource constrained platform like that running Apache is not the best idea. So I set out to (re-)discover the web servers of my past, the late 90’s, I had almost forgotten:

• mini_httpd,
• Boa,
• BusyBox httpd,
• thttpd,
• and more …

Come to think of it, they are probably one of the many reasons that I started my career in embedded in the first place!

Finally, fresh from the oven, here are the remaining two toolchains I’ve promised, based on GCC 6.1 and GLIBC 2.23. Download from the FTP: arm-unknown-linux-gnueabi-6.1.0-2.tar.xz powerpc-unknown-linux-gnu-6.1.0-2.tar.xz x86_64-unknown-linux-gnu-6.1.0-2.tar.xz Unpack into /usr/local, and add to your $PATH, e.g. export PATH=/usr/local/arm-unknown-linux-gnueabi-6.1.0-2/bin:$PATH The toolchains are built using crosstool-NG on Ubuntu 16.04 64-bit, and are primarily intended for myself and users of TroglOS, but are generic enough to be useful for other purposes as well.

First GCC 6.1 based ARM (32-bit) toolchain released on my FTP. Built using crosstool-NG for Ubuntu 16.04 (x86_64) with GLIBC 2.23. arm-unknown-linux-gnueabi-6.1.0-1.tar.xz Download, unpack into /usr/local, and add to your $PATH export PATH=/usr/local/arm-unknown-linux-gnueabi-6.1.0-1/bin:$PATH There’s lots of neat stuff included, both a sysroot and a debug-root with GDB and gdbserver for target. For details on using it, see the excellent docs. The main purpose for my building this is TroglOS, but it is useful for other purposes as well of course. [Read More]

Today the new logo for Finit3 was added to the GitHub repo and the homepage

Gorgeous, isn’t it?! 🕶

This fancy artwork means we’re nearing the end of a long and agonizing release cycle where a lot of the internals of Finit have been rewritten and new exciting features have been added! More on this in an upcoming post 😃
