Android / Eclipse Error generating final archive: Debug Certificate expired

Rowan — Mon, 27 Dec 2010 23:02:22 +0000

It appears the android SDK / debugger generates a certificate in .android/debug-keystore only valid for a year. You may come to generate a new project in Eclipse, go to run the debug / android emulator and find it won’t run.

To fix this, delete the keystore file from your home directory, then run Project [...]

Installing Git on CentOS

Rowan — Sun, 01 Aug 2010 18:37:22 +0000

Git can be found in the EPEL (Fedora Project) complimentary packages repository. The command to install the package will be similar to the following

user@computer:$ rpm -Uvh http://download.fedora.redhat.com/pub/epel/5/x86_64/epel-release-5-3.noarch.rpm

Remember to sanity check this against your RHEL version…

Kubuntu: Rolling back a package

Rowan — Tue, 16 Feb 2010 22:44:03 +0000

Kubuntu is currently my desktop OS of choice for 40+ hours a week of paid eye strain. It’s a good OS, basically Ubuntu with KDE as the desktop environment, however over the three or four years I’ve been using it the quality of the package management GUI applications has been somewhat variable. What we have [...]

Eclipse: new Android project. Can’t select Build Type / Target

Rowan — Sun, 27 Dec 2009 18:13:58 +0000

This caused a good 30 mins head scratching. When creating a new Android project in Eclipse it is not possible to progress past the initial screen as it complains “an SDK target must be specified”. In the window you will see “Build Target” but no box listing your installed Android Versions. The area of the [...]

Slicehost CentOS 5.3 to 5.4 Upgrade (or not much to see here)

It was with a little trepidation that I kicked this one off. However, absolutely no problems what so ever. Nice

Terminal Syntax highligher plugin

Rowan — Wed, 13 May 2009 16:50:38 +0000

I’ve been looking for something like this for a while now to make my quick solutions posts more readable. Only tested it on one post so far but seems to work on latest WP and Thematic. The little plugin allows you to display Linux terminal input / output in a “pretty” fashion in your posts, [...]

yum update – TypeError: unsubscriptable object

Rowan — Wed, 13 May 2009 16:49:06 +0000

Odd error when running yum update on my slice. This appears to be a currently outstanding bug which can be worked around by issuing a

user@computer:$ yum clean metadata

user@computer:$ yum clean all

The former worked fine for me. Original error shown below.

user@computer:$ yum updateSetting up Update ProcessResolving Dependencies--> Running transaction checkTraceback (most [...]

Windows Vista fails to copy large files to network share

Rowan — Mon, 04 May 2009 13:03:04 +0000

Encountered a rather odd error, two HP Vista laptops failing to copy large files to network shares, these would error out complaining about being able to access the source file on the local disk, which was a rather confusing way of reporting the error as there was no problem with the local disk. On network [...]

Slicehost CentOS 5.2 to 5.3 Upgrade (or “fun with package management one”)

Rowan — Mon, 13 Apr 2009 13:16:03 +0000

One of the things about having your own little server, not really used for anything absolutely critical to anyone is that you can install updates as soon as you like. Non critical updates are one of those things that you have to do sooner or later and for non critical systems it can often be [...]

Configuring a Paypal Checkout on Gallery 2

Rowan — Mon, 29 Dec 2008 19:49:53 +0000

These days, gallery is a massive image oriented CMS (so much so that the developers are refocusing on their core objectives for Version 3), with a ton of modules / plugins and themes. It should be no surprise therefore that it’s easy to add a cart / checkout to it.

First, ensure you are [...]
