upgrading to Jekyll 3 · Apr 10, 2016
I went down a 🐇 hole yesterday when I decided I wanted to try a new CSS framework. It started innocently enough, I found Siimple and figured I’d give it a try here. Siimple has SCSS files so I wanted to import them directly rather than used their minified distribution CSS. However, I got an error running Jekyll 2 when importing their SCSS. Though I filed an issue on their repo, I figured maybe it was a problem that would go away if I updated my Jekyll version. I used Chase’s handy gems-cli tool to grab the latest version of Jekyll to put in my Gemfile and, while I was at it, I updated nokogiri, kramdown, coderay, mini_magick, rake, and mechanize, too. I figure if you’re going to upgrade a gem, go big or go home, right?
making a Philips Hue home · Feb 14, 2016
Jon has done a great job getting our house wired up with Philips Hue lights. I’ve really enjoyed having them and with the right devices, they’re very convenient. I love the bits of color and how much control we have over brightness compared with regular bulbs that don’t have dimmer switches. I wouldn’t have known where to get started, so I wanted to write up the products we’ve bought and our experience with lights and devices.
Arel and tags · Jun 19, 2015
I love working out ActiveRecord and Arel queries in Rails apps. I thought I’d share some of the more fun queries I’ve designed in Arel, spread out over a few blog posts. We’ll start with one for fetching tags separated by account.
my collection of OS X Yosemite upgrade fixes · Oct 22, 2014
I upgraded from Mavericks to Yosemite on my MacBook tonight and thought I’d share some of the fixes I had to apply to get my development environment set up again. I’ll continue to update this post as I discover new things that aren’t quite working the same as before.

Switching from WordPress to Jekyll · Jan 21, 2014
Over the course of a little less than a week, I migrated this blog from WordPress 3.8 to Jekyll. I used WordPress for years, probably since 2005 or 2006 when I switched away from Movable Type. I finally decided I wanted something more lightweight than WordPress, and in particular I wanted a blog that would load faster. Jekyll gives me both of those. The part that took the longest to migrate was customizing the new layout, based on Dbyll, and formatting the code examples in my posts.
setting up WordPress mail on CentOS · Sep 13, 2012
Today at work I set up a WordPress install on CentOS Linux so that it could send email. It’s pretty useful and almost required to have this working, since if you forget your password, WordPress needs to send you an email to reset it. That’s how I discovered mail wasn’t set up correctly, actually: a user tried to reset their password and WordPress gave an error about “email could not be sent”, and no email was received. Fortunately it was pretty easy to fix.
simple slider menu with jQuery · Aug 27, 2012
There are possibly a million tutorials out there about jQuery and menus, but there weren’t a million and one… until now! ;) I recently had cause to make a sliding drop-down menu for a project at work and thought I would write up how I did it. First off, check out the demo. The commented source code is below.
custom WordPress Events Manager event tag archive page · Apr 7, 2012
Using the Events Manager WordPress plugin at work, I noticed that the event tag archive pages showed only current and upcoming events with a given tag. I wanted them to show all events, including past events, with the tag. I made a custom loop to accomplish this, within the Genesis framework. Create a file called taxonomy-event-tags.php in your Genesis child theme:
Recently at work I was tasked with creating a customized Portal theme based on the new 18.104.22.168 theme, which uses Dojo 1.6 and thus supports IE9. I followed all of IBM’s steps for making a copy of the 22.214.171.124 theme’s static files (the non-JSP stuff that you can access via WebDAV), but still my custom 126.96.36.199 wouldn’t load for me. I didn’t modify anything in my copy from the original except the metadata to change the theme name. When I would select my copy as a page’s theme or the Portal default theme, I would just get a white page with a snippet of XML up top, sometimes including an error message. When I checked the Portal logs, I saw error messages pertaining to PageBuilder2–what? PageBuilder2 is the old Portal theme, and the new 188.8.131.52 theme didn’t seem to mention PageBuilder2 anywhere. If you’re experiencing this, here’s what I did to fix it.
Portal 7 mobile theme installation woes · Nov 3, 2011
I hassled with trying to install the IBM WebSphere Portal Mobile Experience, following the instructions on IBM’s web site, but the theme never showed up on my Portal site. Turns out you need to go into your IBM/WebSphere/PortalServer/theme directory and edit components.properties. There should be one line in there:
Converting a Word .docx file to a PDF on the iPad · Apr 5, 2011
In case anyone else has the need to do this, I’ll explain how I converted a .docx file to a PDF on my iPad 2. The fact that I feel the need to write a tutorial on how to do this should be a big hint to the folks at Apple that their file management system, or lack thereof, needs work. :/

I just encountered Grub Error 13 and Grub Error 17 for seemingly no reason. I fixed the problem and thought I could save others undue headache by explaining my fix here.
make your Mac listen up · Feb 4, 2008
I’m so tickled I can’t stand it. All right, so Speech Recognition stuff on a Mac is pretty darn cool by itself, but now I’ve got a nice Apple Script that opens up Safari with various tabs of my favorite sites, and it does this when I tell my Macbook “Get on it.” Here’s how I did it:
Grub Error 17 · Oct 25, 2007
Note: if this tutorial doesn’t help you, possibly because
fdiskreports your known Linux partition correctly as Linux, you might also try my Grub Error 13 with Grub Error 17 tutorial.
I just had an interesting time with trying to boot into Linux on my PC. Last night, I noticed my
/boot/grub/menu.lstfile had gotten overwritten when I performed some Ubuntu updates. This meant I had to add in configuration to allow Windows to boot, and since I didn’t have a backup of my old, working configuration–mistake number 1–I looked online. I found something that looked like it would work, even though it had Grub’s
unhidecommands in the configuration–mistake number 2. I rebooted and successfully got into Windows.
using AJAX to implement a live search · May 14, 2007
using AJAX to spiff up a gallery · May 3, 2007
Lightbox is nice and all, but sometimes I find it clunky, particularly in Firefox when I have a lot of other tabs open. However, I don’t want to go the route of having an image load by itself in the browser, because it would be so much nicer to have it integrated into my layout. I could have a whole bunch of separate pages, one for each image, and do a full page load when a thumbnail is clicked, but that’s kind of a hassle. Well, with a simple PHP script and some AJAX calls, I can have my image load within the gallery page without a page reload.
how to reformat your pen drive · Apr 19, 2007
USB pen drives are everywhere these days, and for good reason, since they’re dead useful. I use mine with my Linux box, my Powerbook, and various other systems I’ve had cause to stick it in. After a while, my 1 GB drive was only holding a few hundred MB. When I would do an
ls -aon it, I would see several hidden directories, such as .Trashes and .Trash-sarah. Trying to
sudo rm -rf .Trash\*would fail out, however, giving complaints of a read-only filesystem. If you’re having such problems, or just really want to make sure your drive is clean, you can reformat it easily in Linux. I reformatted mine using Ubuntu, so the instructions have a slight bias; your mileage may vary. Warning: reformatting your pen drive will delete all its contents.
using Perl and Apache on OS X · Mar 22, 2007
I’m trying to do some work with a Perl app on my Powerbook but I was unable to get any Perl scripts to execute from my local server. At first, I was getting just the source of the Perl files spit back at me. I followed a few tutorials about getting /etc/httpd/httpd.conf set up, but then I kept getting 403 Forbidden errors when I tried to access .pl or .cgi files in my browser. I checked /var/log/httpd/error_log and saw:

if succinctly · Jun 7, 2006
ifis an expression, not a statement, thus it returns a value. This may not seem useful at first glance, but it lends itself to forming neat, concise code… Like most things in Ruby, actually.
the power of yield and super · May 28, 2006
The two keywords
superallow you to pass control back and forth between parent and child methods, to weave power between a more general method (in the parent class) and a more specific method (in the child class) with ease and logic. Using
supereffectively can help you maintain the DRY (Don’t repeat yourself) principle, keeping your code easier to maintain.
image generation in PHP · Mar 11, 2006
Creating images on-the-fly can be a very useful skill. Using PHP’s built-in image generation functions, it’s pretty easy, too. This tutorial will detail how to have the titles of blog entries show up as automatically generated images.
ad blocking through /etc/hosts · Mar 4, 2006
There are several ad sites that you’ll see being used everywhere. They slow down page loading, even on fast connections, because sometimes there’ll be lag and they won’t load immediately and instead of being able to read that interesting news article, you’re stuck waiting for some Flash animation to show up so you can ignore it. A simple way to make those ads 1) not show up and 2) not cause delays in page loading is to edit /etc/hosts. Check out hostsfile.mine.nu for ways of doing this in Windows and Mac.
non-English characters in Linux · Dec 28, 2005
It’s easy to make accented characters (e.g. é and ü) in Linux. Easier than in Windows, actually, because in Windows you have to remember all those crazy Alt codes, and in Linux, it’s logical combinations of accents and letters.

Makefile · Nov 15, 2005
In a Unix environment when working with C++ or C, a Makefile can be a very handy thing. Instead of typing several separate commands each time you update a file and want to recompile, you can just type
makeand the Makefile is executed.
random quotes with PHP · Jun 8, 2005
So you want to display a randomly selected quote on your page, and you want to use PHP to do it; you’ll need PHP support on your server. An easy way to test this is to stick
<?php phpinfo(); ?>into a .php file, upload that file to your server, and load it in your browser. If you get a huge table with information about your PHP setup, then you know you have PHP support. If you get a blank page, then you don’t have PHP. :(
more dynamic sites through PHP · Jun 8, 2005
A couple of reasons to use PHP in your site:
