Finally I’m going to SXSW in Austin, TX this year. Now I get to be one of the cool kids. Or something like that.

Pictures from the trip:

I was just working on making some updates to the backend WordPress code for the Principia Pilot website (http://principiapilot.org/) and noticed widows in some of the stories.

Widows are the typographic term for a single word on a line at the end of a paragraph. I thought about the solution to this problem (basically add a non-breaking space before the last word of a paragraph) and then realized probably someone had written a plugin to do exactly this.

I tried two different plugins and like this one the best because it doesn’t overwrite the rest of the excellent WordPress typographic niceties like converting straight quotes to curly quotes:

One of the neat things about WordPress is how easy it is to add custom metadata to a given page or post that you can then use in a template to display structured information. I’ve been using this technique for a while now to extend the basic WordPress elements of title, body, excerpt, etc and allow the creation of easily editable information-rich content.

Before now I’ve used the built-in WordPress Custom Field functionality in the Add New screen where you select previously created custom fields from a drop-down list that is limited to only showing 30 items. This is quite cumbersome as you have select each field you want to add to the entry and enter the value, click the Add Custom Field button, then repeat for however many custom fields you want to use. Needless to say, this can be frustrating to have to remember to do every time, especially for non-technical clients.

The Old Way:

During a recent site conversion to WordPress that involves 4-6 custom fields for each post, we finally decided that there must be a better way, and ended up finding a WordPress plugin that is so good that it should probably be added to WordPress core, it is so highly useful. The plugin is called Custom Field Template and is developed by Hiroaki Miyashita.

The New Way:

Using a simple set of options to define the template you want to use is easy. After downloading and activating the plugin, go to Settings > Custom Field Template to define your template. One is provided for you to show you the possible template values. You can set up two separate custom field template designs.

This is the code used to generate the Custom Field Template form shown in the screenshot above:

Template Instruction

<strong>Story Template Metadata Instructions <em>(All fields are optional)</em></strong><br /><br />
1. Use this form to enter metadata about this story.<br />
2. Each item will get assigned to the correct Custom Field for use in the display template.<br />
3. Click the <strong>Save</strong> button to save the values.<br />
<br />

Template Content

[summary_deck]
type = textarea
rows = 3
cols = 50
label = Summary Deck:

[byline_writer_name]
type = text
size = 35
label = Byline Writer Name:

[byline_writer_title]
type = text
size = 35
label = Byline Writer Title:

[byline_writer_picture_url]
type = text
size = 54
label = Byline Writer Picture URL:

[lead_photo_caption]
type = textarea
rows = 3
cols = 50
label = Lead Photo Caption:

[lead_photo_credit]
type = text
size = 35
label = Lead Photo Credit:

[lead_photo_url]
type = text
size = 54
label = Lead Photo URL:

Then set this setting to true by checking the box to make the form look prettier:

Next, I tweaked the Admin CSS settings to right-justify the labels:

#cft dl { clear:both; margin:0; padding:0; width:100%; }
#cft dt { float:left; font-weight:bold; margin:0; padding: 0 8px 0 0; text-align:right; width: 20%; }
#cft dt .hideKey { visibility:hidden; }
#cft dd { float:left; margin:0; text-align:left; width:70%; }
#cft dd p.label { font-weight:bold; margin:0; }
#cft_instruction { margin:10px; }


Click Update Options to save the settings and then go to Posts > Add New to see the form in action. You may need to go back and forth a couple of times to get your text field sizes just right and to put them in the right order you want them in.

Using the Custom Fields in a template

So how do these values get displayed on your page?

Simply edit your template PHP file to look for custom field values and then display them where you want them if they’re present.

This is how I do it for the Principia Pilot site. This code goes at the top of the template for single.php

<?php
// Retrieve custom meta values from post if they're present
$byline_writer_name = htmlspecialchars(get_post_meta($post->ID, "byline_writer_name", true));
$byline_writer_title = htmlspecialchars(get_post_meta($post->ID, "byline_writer_title", true));
$byline_writer_picture_url = htmlspecialchars(get_post_meta($post->ID, "byline_writer_picture_url", true));
$lead_photo_url = htmlspecialchars(get_post_meta($post->ID, "lead_photo_url", true));
$lead_photo_credit = htmlspecialchars(get_post_meta($post->ID, "lead_photo_credit", true));
$lead_photo_caption = htmlspecialchars(get_post_meta($post->ID, "lead_photo_caption", true));
$summary_deck = wptexturize(get_post_meta($post->ID, "summary_deck", true));
?>


Now each of the possible Custom Fields are available as PHP variables that can be checked for content.

This code example shows the “summary deck” being displayed on the page if it has been entered on the create content screen:

<?php
// Show summary deck if we have one
if ($summary_deck != "") {
    echo '<h3 class="summary-deck">' . $summary_deck . '</h3>';
}
?>


Using this excellent plugin, you can set up select lists, radio buttons, check boxes and more to help you populate your Custom Fields more easily if you prefer that to using simple text fields. You can also specify default values to use for the custom fields so you don’t have to type them in every time.

Plugin Default Template Options

These are the default options included by the plugin:
[Plan]
type = text
size = 35
label = Where are you going to go?

[Plan]
type = textfield
size = 35
hideKey = true

[Favorite Fruits]
type = checkbox
value = apple # orange # banana # grape
default = orange # grape

[Miles Walked]
type = radio
value = 0-9 # 10-19 # 20+
default = 10-19
clearButton = true

[Temper Level]
type = select
value = High # Medium # Low
default = Low

[Hidden Thought]
type = textarea
rows = 4
cols = 40
tinyMCE = true
mediaButton = true

Which displays a form that looks like this:

Summary

This plugin addresses a key need when using Custom Meta Fields in a WordPress custom template design — making it as easy as possible to enter values time after time on multiple pages or posts. There are a bunch of other neat options this plugin offers to make the authoring experience even easier. This is now on my “must install” list of essential WordPress plugins.

A neat trick if you have a Mac OS X machine is to do this (make sure your speakers are turned on):

1. Open Terminal.app
2. Type in at the command line: say hello world

This will make your computer say “hello world” in the default voice (Victoria).

Here is a list of the other voices you can also use:

Female Voices

• $ say -v Agnes "hello world"
• $ say -v Kathy "hello world"
• $ say -v Princess "hello world"
• $ say -v Vicki "hello world"
• $ say -v Victoria "hello world"

Male Voices

• $ say -v Bruce "hello world"
• $ say -v Fred "hello world"
• $ say -v Junior "hello world"
• $ say -v Ralph "hello world"

Novelty Voices

• $ say -v Albert "hello world"
• $ say -v "Bad News" "hello world"
• $ say -v Bahh "hello world"
• $ say -v Bells "hello world"
• $ say -v Boing "hello world"
• $ say -v Bubbles "hello world"
• $ say -v Cellos "hello world"
• $ say -v Deranged "hello world"
• $ say -v "Good News" "hello world"
• $ say -v Hysterical "hello world"
• $ say -v "Pipe Organ" "hello world"
• $ say -v Trinoids "hello world"
• $ say -v Whisper "hello world"
• $ say -v Zarvox "hello world"

Have fun. You can now add voices to your monitoring applications, or freak people out if they don’t know about this cool trick.

First, the good news: Matt & his brave crew of WordPress coders have just released version 2.6 of the Open Source award-winningly awesome content management system called WordPress (download it here). I’ve been using it since it was called b2, and love it. I recommend it for most of my clients, and they love the simplicity and ease of use. I also really like how easy it is to customize and extend, using the excellent theme and plugin system.

If you have a WordPress installation yourself, please upgrade it today. Why should you do it today? In short, not only does the latest version of WordPress have some awesome new features (like content change tracking, a new “Press this” browser bookmark, using Google’s Gears system to make it faster, and about 194 bug fixes) it also contains the latest SECURITY FIXES.

Why should you care about security fixes? Because older versions of WordPress are vulnerable to exploits. I know this for a fact, and have been working on cleaning out a number of older installations of WordPress that have been hacked. This isn’t a fun process, and if you stay up to date, you will have the best chance of not getting hacked yourself.

This isn’t a problem exclusive to WordPress, and they’ve done a really good job generally at fixing holes (the current release proactively fixes a number of potential issues), but it is an issue you should definitely look into.

On a Unix machine, one thing to look for is this pattern in any files: md5($_COOKIE'

You can do a search through all your hosting accounts by running this command (run as root):
# grep -R 'md5($_COOKIE' /home/

That will tell you if you have any infected files (for this particular exploit). If you find any, you need to clean out those files. If you are running your sites out of version control (like using svn), this may be slightly easier.

$ svn st should tell you if any files were changed from the last time you checked them out. If you see unexpected files show up, you’ve been hacked.

To clean out your installation, not using version control method (done as root in this case):

1. Copy your whole public_html directory to another location so you can do forensics on it and copy valid files back into your new installation:
   # cd /home/USERNAME/
# mkdir public_html-hacked
# mv public_html/* public_html-hacked/
2. Download a clean copy of WordPress into your public_html:
   # cd /home/USERNAME/
# wget http://wordpress.org/latest.zip .
# unzip latest.zip
# cp -R wordpress/* public_html/
# chown -R USERNAME:USERNAME public_html/*
3. Create a new wp-config.php file. It’s probably a really good idea to first change your MySQL database password. To create your new config file:
   #cd public_html/
# cp wp-config-sample.php wp-config.php
# vi wp-config.php
   Enter the correct (new) values for your MySQL database name, username, password, and the (currently 3) authorization unique key values (go to http://api.wordpress.org/secret-key/1.1/ to automatically generate the 3 keys for you to copy/paste into your config file.
4. Next, upgrade your WordPress database: http://example.com/wp-admin/upgrade.php. You’ll have to sign in with your admin username and password. Once this is done (should go without a hitch, hopefully), examine your user table to see if there are any entries there that shouldn’t be. Delete any users that you didn’t create. Also, it would be a good idea to update the password for each user in the system.
5. Go through all of your Settings, looking for any suspicious changes. Specifically notice what the Uploads directory is set to (in Settings->Miscellaneous). It should probably be set to something like wp-content/uploads. If it says something like ../../../../../tmp/ change it back. Also go look there to see if there are any left-over files that need to be investigated and removed.
6. Make a local copy backup of your database and then clean out entries that don’t belong there. Check your raw database (using something like PHPMyAdmin or command line mysql tools) and examine the wp_users table. Look for a user called WordPress. Delete it! If you found it, also check the wp_usermeta table and delete all entries associated with the bogus WordPress user ID. Next, check through your other MySQL tables to look for any suspicious entries (attached files, comments, posts, etc.) Delete anything that looks incorrect or wrong, but be sure not to delete your actual content.

As you can see, there are lots of things to check for if your installation of WordPress gets compromised. So, to save yourself a lot of pain and suffering, make sure you upgrade your WordPress installation(s) just as soon as you can.

More good info if you think your WordPress installation has been hacked:

• Has Your WordPress Been Hacked Recently?
• WordPress Support: Security issue, multiple sites
• Search the WordPress support forums for “exploit”
• Specific WordPress Codex information about this exploit
• Doncha’s excellent (and more recent) write-up of how to deal with a hacked WordPress installation

Let’s say, hypothetically, that you are a designer, and are working on a design comp for a Christian Science church or reading room, and you wanted a high resolution vector version of the logo to use in your mock-up so you didn’t have to chop out background garbage out of some low-resolution version of the logo you found on the web somewhere. What should you do?

In the Cross and Crown trademark licensing documentation, you will find the following instructions:

Two approvals are necessary:
(1) for your type of use (sign, etc.) and
(2) for the actual form of your use (how the sign appears).
Therefore, if you already have a sample or mock-up of the proposed use, please send it by e-mail or regular mail along with the Request Form, so both approvals can be done simultaneously. It will save you time later.

Unfortunately, they do not currently provide any links to a high-resolution version of their logo for purposes of laying out a design, which would be very helpful to all the designers out there trying to help their clients prepare a mock-up of the proposed usage.

Update: I’ve removed the instructions for how to extract a vector version of the logo out of a PDF since they’ve changed the PDF available on their site to only include a raster version now, and it would probably be more helpful to more people in the long run if they hear the need for a vector version for placement in design comps from a number of people rather than trying to work-around the system they’re offering.

My suggestion is you contact the trademark administrator directly and request a vector version of the logo if the high-resolution JPG version of the logo isn’t sufficient for your usage. Their email address is trademark@csps.com.

In preparation for upgrading a whole mess of sites to using the latest version of WordPress I decided it was time to finally upgrade my own site and to implement the new design I’d been working on for a while (for over a year now).

As part of getting an upgraded server set up and transferring sites from the older server, I had to re-install PEAR XML_RSS. One of its dependencies is XML_Tree.

Normally, this command should have worked with no problems:

pear install XML_RSS

It downloaded XML_RSS just fine, but then choked on XML_Tree, which was a required dependency.

Initial output:

# pear install XML_RSS
Did not download dependencies: pear/XML_Tree, use --alldeps or --onlyreqdeps to download automatically
pear/XML_RSS requires package "pear/XML_Tree"
No valid packages found
install failed


My next try was to specify installing XML_Tree:

# pear install XML_Tree
WARNING: "pear/XML_Tree" is deprecated in favor of "pear/XML_Serializer"
downloading XML_Tree-1.1.tgz ...
Starting to download XML_Tree-1.1.tgz (4,826 bytes)
.....done: 4,826 bytes
XML error: not well-formed (invalid token) at line 10
Download of "pear/XML_Tree" succeeded, but it is not a valid package archive
Error: cannot download "pear/XML_Tree"
Download failed
install failed


After some troubleshooting, here is how I fixed this problem:

1. Change directory into the PEAR download cache directory: cd /tmp/pear/cache/
2. Clear out all the old cache files: pear clear-cache
3. You should see the downloaded file: XML_Tree-1.1.tgz
4. Extract the files: tar xvfz XML_Tree-1.1.tgz
5. Now edit the extracted package.xml file: vi package.xml
6. Go to line 10 and change the ö to an o. This is the character that is causing the XML validation of the package file to fail. Next, save the file (ESC :wq)
7. Next, remove the old .tgz file: rm -rf XML_Tree-1.1.tgz
8. We’re going to recreate the package: tar cfv - package.xml XML_Tree-1.1/ | gzip > XML_Tree-1.1.tgz
9. Next, we’re going to install this package and not use the network: pear install -O XML_Tree-1.1.tgz

XML_Tree is now installed. You should now be able to continue installing XML_RSS normally.
