Cleaned up my Pedal Board

Just a quick post about my pedal board before and after I cleaned it up. 3M Dual Lock tape helped to make this look flawless.

Proper Grill Cloth for my Guitar Cabinet

Today I felt like improving my guitar speaker cabinet which I’ve built a while ago. I was never happy with the round metal grill I have put in front of the speaker.


Instead I wanted a grill cloth in front of the speaker but by the time I built the cabinet I didn’t think much about it.

Today I went out and bought some wood to make a simple frame for the grill cloth.


Then I put the grill cloth on which is quite challenging but there are guide on the internet that show you how to do it. Basically you start at one side and attach it with a big stapler/tacker – you now the ones which shoot the needle/clamp into the wood. Then you pull it over the opposite side with as much tension as possible and attach it. Same for the remaining two sides.

The result:


Fun little project for the afternoon.

New FreeBSD Screencast Episode about CARP

Today I’ve tried out CARP, the Common Address Redundancy Protocol, which allows you to easily set up automatic failover for machines which usually become single points of failure in your infrastructure like loadbalancers, firewalls and routers.

It was so easy and quick that I made a short video demonstrating it:


# Machine 1
ifconfig carp0 create
ifconfig carp0 vhid 1 advskew 100 pass foobartralala

# Machine 2
ifconfig carp0 create
ifconfig carp0 vhid 1 advskew 200 pass foobartralala

If you want to make that set up permanent put something similar to your /etc/rc.conf:

ifconfig_carp0="vhid 1 advskew 100 pass foobartralala"

Erlang R16 64Bit on OS X 10.9 with wxWidgets

A lot of people have tried to get Erlang running on OSX with 64Bit and wxWidgets and there are plenty of guides out there but most of them claim that it doesn’t work with 64Bit.

I just successfully compiled it as 64Bit on 10.9.2 and here is how I did it:

1. I installed wxWidgets and Erlang from homebrew and deinstalled them again, just to get all the dependencies conveniently
2. Then I fetched the sources for wxWidgets 3.0 from sourceforge and the sources for Erlang R16 from the erlang website
3. I configured them with a blend of options from the official docs and the other guides

Configure and Compile wxWidgets

./configure --with-cocoa --prefix=/usr/local \
            --with-macosx-version-min=10.9 --disable-shared

make install

Configure and Compile Erlang

./configure --disable-debug --without-javac --enable-shared-zlib \
            --enable-dynamic-ssl-lib --enable-hipe \
            --enable-smp-support --enable-threads \
            --enable-kernel-poll --with-wx --enable-darwin-64bit

make install

Thats was it. I hope that helps.

Getting Started with FreeBSD

I’m a huge FreeBSD fan. My very first home router ran FreeBSD back in the late 90′s and since then I have installed it on every single server I worked with. I do realize that this is some kind of niche since almost everybody else is running Linux these days. This is why I thought to make FreeBSD a little bit more approachable to the curious people.

Why? Because FreeBSD offers a lot of cool features like ZFS, Jails, reliability, stable API and a great network stack which makes it a really superb server operating system. In fact I just realized I never had to clean install any of the many FreeBSD machines I have operated. They just kept running flawlessly unless some hardware died of course.

To get you started I have recorded a little screencast to show how easy and painless it is to install FreeBSD 10.0 with a ZFS root filesystem on a remote machine even if the hosting provider does not provide FreeBSD rescue images.

In the next videos I’ll show you how to install software, set up a web server and other common, server related tasks.

For that I have created a FreeBSD Guides channel on vimeo.
