I've had my Samsung Galaxy Nexus for a little over a year now.

I've received updates from Samsung from Ice Cream Sandwich, to Jelly Bean. However, a recent OTA update for Jelly Bean to Android 4.2.1 left my phone sluggish and frustrating to use.

I'd read some of the reports here, and here, and decided in the end that I was ready for something a little more drastic.

I've been hacking on Drupal recently and so far, I like it a lot. I've also been reading a little about Drupal's deployment story, and decided that it might be fun to use Capistrano to deploy the projects I'm working on.

Turns out I'm not the only one that's thought of it. Kim Pepper's approach is excellent, and he's included his Capistrano tasks on Github.

Here's my take, which is a little different from Kim's in so far as I am not that concerned about the 'Rail-isms' that come with the default Capistrano gem (for the moment at least).

Here's a recipe for adding (and formatting) captions to images in Drupal using Entity View Modes, File Entity, and Media 2.0. A word of warning first. All of the required modules are either unstable or dev releases and so for those not willing to deploy these modules to a production Drupal install - this article should at the least give you an idea of what's possible and what's coming.

Design Goals

The objective is to allow a user to upload or select an image using the Media module, as well as choose a layout for the image. The media embed tags (non-HTML) placed into the body of the node/post will then be filtered by the media module, resulting in markup containing an image, surrounded by div elements with appropriate class attributes for position and styling. jQuery, or client-side JavaScript will not be required, and there will be a dedicated caption field. No other specialised 'captioning' or image modules will be required.

Requirements

You'll need all three of the above modules at the following releases: File Entity 7.x-2.0-unstable7 Entity View Modes 7.x-1.0-beta3 Media 7.x-2.x-dev

Bash is fun. I mean it's a little weird, but it's fun. I've been reading the Linux Command Line and Shell Scripting Bible which I highly recommend. I also wanted a script I could use to update the multiple WordPress installations I'm now hosting.

I found Liz Quilty's handy WordPress mass update script 3.4.1, but wanted to refactor the script to use functions, curl, and tar (as well as remove support for WordPress MU)

And so here it is, one of a handful of Bash script exercises I've completed to-date. Enjoy, and thanks Liz for the head start.

First, a machine specific configuration file (read the warning in the comments section of the script below). Place the config file next to the script file; that is, place wp-upgrade.conf in the same directory as wp-upgrade.sh.

I recently suffered a UDP flood attack on my little virtual private server (VPS), and thought I'd describe the steps I went through to discover and fix the problem.

Symptoms

Periodically, my server would stall and become unresponsive. It was effectively dead, although not down. These 'stalling' events would last from 5-20 minutes, and then the server would come back up. Looking at my Munin charts told me that my public ethernet interface (eth0) was being flooded. Here's a particularly bad day:

And this was after I had rate limited eth0 to 2mbits/sec using tc (more on tc in a bit). CPU usage and interrupts for eth0 also spiked. So something was flooding eth0, and stalling the server.
