Shibboleth SP logo.jpg missing from distributions

Have you recently installed the Shibboleth SP software and found that the error pages the software is generating are missing the Shibboleth logo? If so, it’s because those error pages are attempting to display a logo (typically /shibboleth-sp/logo.jpg by default) but the logo of the Griffin that you may have been used to seeing is no longer distributed with the software.

Unfortunately, this change doesn’t appear to be documented (yet), but is highlighted in this discussion: http://shibboleth.1660669.n2.nabble.com/Shibboleth-logo-in-Red-Hat-RPM-tp7583386.html

More or less, the reasoning given is that the Shibboleth …

Restart/reset USB in Ubuntu 12.04 without rebooting

Either my Dell Optiplex 990 computer or my Linux install has an issue: occasionally, when I re-plug a USB device into the system, it’ll cause a fault in the USB module in the kernel and USB goes dark. I’m unsure as to whether this is a hardware or software issue, but I’d simply like to restart my USB subsystem and continue working. When searching the web for ‘restart USB in Linux’ and ‘reload USB kernel module’, you get a plethora of results and none of which will work (seemingly due to how the Ubuntu standard kernel is …

Easier GitHub organisation, repository and team management with github-collective

Have you ever felt that administering your GitHub organisation (or organization, depending from where you hail), its repositories, teams, and service hooks has become a tedious task and that you’d rather be doing something else?  Maybe you’re of the mindset that there should be a better way of doing things - a way that involves specific, version-controlled configuration and less repetition (less clicky-clicky).  The good news is that there is — github-collective!

This is a script, written in Python, that utilises GitHub’s JSON-based API to allow you to construct an ini-style text-based configuration representing your GitHub organisation and …

Building Cherokee RPMs on RHEL 6 (x86_64)

Cherokee is a fast web server and something I’m looking at using instead of my current Apache installs in order to squeeze a bit (lot) more juice out of my web services.

You can easily install Cherokee via its automated scripting and that’s really useful.  Unfortunately, since I’m within a RedHat environment, init scripts and other useful aspects that come packaged with Apache don’t get installed when installing from source. Now, there’s a lot of activity regarding installing the latest packages for Ubuntu, but not much of anything recent for RHEL (current Cherokee is 1 …

Bailing on Outlook Web App (Windows Live) and using Gmail with POP/SMTP instead

I’m not a fan of Microsoft’s solutions for mail (Exchange, Outlook, Outlook Web Access, etc) because they simply aren’t as smooth as other alternatives. In my case, my weapon of choice is Gmail for all my mail. Unless you really like the old-school style popup windows and Web 1.0 feel of Microsoft’s options, you’re probably opting for something else, too. Now, there’s no helping my institutional mail account as they’ve disabled all standards-compliant forms of access (POP, IMAP, SMTP; short of going down the route of DavMail). But, that said, there is …

Apache: Directories and trailing slashes

Apache does something interesting (yes, I still think it’s logical) when you’re accessing a directory that it’s serving: if you access it without a trailing slash, it’ll add one by default. This makes sense if you’re going after some static content or a folder index (or pretty much any sane usage) but it didn’t fit my use case of serving Plone using rewrite rules in a .htaccess file.

The issue that arises for myself with Plone is that my sites need to have their access customised through that .htaccess file and that’s been …
