Adding a return URL during logout with CAS

David — Wed, 11 Jan 2012 01:38:34 +0000

CAS (Central Authentication Service) is a single-sign-on service (say that several times quickly) and through accessing a CAS /logout URL, as an application, you’re able to log the given user out. What wasn’t clear (by Googling) was whether there’s a possibility to redirect the user back to the original application (or a given URL). I [...]

Configuring pulseaudio-equalizer defaults

David — Fri, 16 Dec 2011 01:26:55 +0000

I’ve recently been using the Logitech G930 headset with my Ubuntu 11.10 install and I’ve found that the default configuration offers nothing in terms of decent sound (tinny, no bass, etc). Thankfully, I’ve been able to turn to pulseaudio-equalizer for help with turning down the treble and up the bass. However, using pulseaudio-equalizer-gtk wasn’t an [...]

Notes about Redmine and GitHub Post-commit Hooks

David — Wed, 14 Dec 2011 00:50:57 +0000

We’re currently using Redmine for our project tracking and recently have wanted to have our GitHub projects automatically get updated within Redmine. A post-commit hook to the rescue! Download and install this super plugin: https://github.com/koppen/redmine_github_hook and restart your Redmine instance. Set up your local Git instance for your repository. This is simple, but you need [...]

User IDs show as comment authors in Plone 4.x after migration from plone.app.discussion

David — Tue, 01 Nov 2011 03:18:39 +0000

If you’ve migrated your site from earlier versions of Plone to the latest ones in the 4.x series, or else have started using plone.app.discussion earlier than that, you might have come across a situation where comments on your site show user IDs as authors rather than a user’s full name. If you see this anywhere, [...]

Logitech G930 Headphones audio quality under Ubuntu

David — Sun, 23 Oct 2011 23:28:40 +0000

So I recently purchased a new set of Logitech G930 headphones and am currently using them with the latest version of Ubuntu, 11.10. Set up was a breeze – just plug, check your PulseAudio config, and play. For those of you, like me originally, who were wondering whether the G930 works on Linux, it certain [...]

RSS Feed for OCZ Vertex 3 SSD firmware updates

David — Thu, 20 Oct 2011 08:04:13 +0000

Here’s a quick and dirty solution to me not being able to keep updated with OCZ firmware updates for my Vertex 3 SSD. For whatever reason, OCZ doesn’t provide a news feed of firmware updates (that I know of, correct me if I’m wrong!) so I’ve sorted a screen scraping Yahoo Pipes pipe to do [...]

Dell SK-8135 keyboard not working during boot (POST, BIOS, GRUB) on OptiPlex 990

David — Thu, 20 Oct 2011 05:19:22 +0000

Update: Since this was written, Dell has released version A10 of their OptiPlex 990 BIOS! I’ve tested this on my 990 and my keyboard now works! Just a quick note to anyone out there confused out of their mind if their Dell keyboard isn’t working with their computer during boot: there is some incompatibility between [...]

Epic-sized (Really Large) Files with Plone 4.1.2

David — Wed, 12 Oct 2011 06:10:32 +0000

In case you were ever curious, it’s definitely possible to upload epic-sized files within the Plone CMS. Browser support aside (Firefox and your 2 GB limits, I’m looking you), I’d previously had issues with being able to upload files larger than 4 GB, if memory serves correctly. Previously, there was an issue with files causing [...]

AttributeError: ‘NoneType’ object has no attribute ‘items’: Can’t upgrade Plone 3 to 4.x

You may have seen an error like the one below when you’ve gone to upgrade your Plone site to something in the Plone 4.x series from Plone 3: 2011-09-14 08:43:32 ERROR plone.app.upgrade Upgrade aborted.

SCP remote files back home using reverse SSH (in 1 command)

David — Tue, 13 Sep 2011 02:55:03 +0000

My recent work has involved copying files from a remote host, only accessible via a hop, back to my local computer. This has been simple in the past as the remote host has been able to connect to the local computer and SCP files directly, on account of the firewall allowing this. Recently, the firewall [...]
