Re-installing MacOS should be a piece of cake. Just go into recovery mode by pressing Command+R during boot and start recovering. It should be… But that is only true for the common case.

Automatic Ubuntu Kernel Clean Up Foo (Update)
Cleaning up old kernel images on a Ubuntu machine is a quite annoying task. If you forget it and you have a separate /boot partition, then you will sooner or later run out of disk space. And then of course all your updates will fail. Doing the clean up manually is, as mentioned, more than… Continue reading Automatic Ubuntu Kernel Clean Up Foo (Update)
The Apache “Could not reliably determine the server’s fully qualified domain name, using 127.0.1.1 for ServerName” Foo on Ubuntu
If you are using Apache on Ubuntu, then you most likely ran into the annoying warning about determining the fully qualified domain name of your server. Something like this will show up in your logs, on start of the server or on log rotation: apache2: Could not reliably determine the server’s fully qualified domain name,… Continue reading The Apache “Could not reliably determine the server’s fully qualified domain name, using 127.0.1.1 for ServerName” Foo on Ubuntu
Windows 7 “The Computer Restarted unexpectedly or encountered an unexpected error” Foo
HP’s Windows recovery installation seems to be a little bit broken. Or at least for me it was. While restoring the Windows 7 on an HP Elitebook 8540w I ran into some issues when the drivers installed. The system just stalled and nothing was moving anymore. After a reboot I saw this nice error message:… Continue reading Windows 7 “The Computer Restarted unexpectedly or encountered an unexpected error” Foo
Too Many Open Files Foo With Chrome On Ubuntu 13.10
The last Chrome update and one of the last Thunderbird updates caused some strange crashes of either on of them on my Ubuntu 13.10. All is fine, it runs great and all of a sudden *boom*, browser window gone, or email client gone. Luckily .xsession-errors exists and there I could find some entries like this:… Continue reading Too Many Open Files Foo With Chrome On Ubuntu 13.10

BIND Journal Foo
After doing some updates to my DNS set up I ran some standard checks. And it took me a while to realize that for some reason my zone didn’t load correctly and the secondary server was used. So I dove into the logs and low and behold I saw this: zone dusares.com/IN: journal rollforward failed:… Continue reading BIND Journal Foo
Re-Assign Host Access Permission For User In MySQL Foo
Changing the configuration of a VPN can have interesting side effects. In my case I had to open up the host permissions for my MySQL users and databases from a /24 to a /16 network. Should be easy… and it actually is. Here are the SQL commands you have to execute to perform such an… Continue reading Re-Assign Host Access Permission For User In MySQL Foo
Amazon AWS SSL Certificate Import Foo
Using Amazon’s Elastic Load Balancer (ELB) with SSL is supposedly an easy thing to set up. And for the most part it is. You can use the command line tools or the web interface and all is good. But it seems Amazon messed up a little bit the error messaging. When uploading our SSL certificate… Continue reading Amazon AWS SSL Certificate Import Foo
Wicd On Ubuntu Fails To Start Foo
Running Ubuntu, like most mainstream Linux distribution, means nowadays automatically that your computer gets exposed to the NetworkManager and its sideeffects. Maybe this tool might work for some desktop users, but it definitely never worked for me. It is cumbersome to configure, doesn’t like if an interface is managed manually or you want to change… Continue reading Wicd On Ubuntu Fails To Start Foo
