How to Simply Rip DVDs in 64-bit Windows

Handbrake iconIn the past, we’ve looked at how to easily rip DVDs on the Windows platform. That method still works great, unless you’re on a 64-bit version of Windows. For those of us now running Windows 7 64-bit, we have a problem: DVD43 – a required decrypter used in the previous tutorial, does not get along well with 64-bit versions of Windows.

The Solution – Handbrake with libdvdcss

There’s an easy solution to this problem, and it only requires the installation of one software program. I’ve migrated to the mighty Handbrake for all my DVD rips. First, install the 64-bit version of Handbrake. As of this writing, the latest version is 0.9.6. Continue reading How to Simply Rip DVDs in 64-bit Windows

How WordPress Destroyed the Internet

WordPress is so popular that it is taking over — it’s behind 22% of all new sites on the internet, but this sets a dangerously poor coding standard. Our infrastructure is crumbling!

Yes, this is a rant. My beef today is this: the WordPress manager might be easy to use, but under the hood, it sucks. There, I said it. It’s awful architecture and it has taught thousands of web developers that it’s Ok to write piss-poor code. This has single-handedly dumbed-down a whole generation of developers by setting a bad example. WordPress is the junk food of coding standards: ubiquitous, tastes good, but lacking any nutritional value.

I’ve ranted about WordPress before but what put me over the top today was the Suffusion Theme. It looks like a clean layout, so I thought I’d give it a try. Holy flaming monkey balls, was I in for a shock!

Review of Web-based Project Management Software

Help! I gotta keep track of everything I gotta do! There is help available to track your projects, you just got to know where to look.

A lot of developers, designers, students, and even web-hobbyists have a lot of items on their to-do lists for any particular site or project. You have to remember to fix that one CSS glitch, or rewrite a page to use some new function… the lists can be long and daunting. If you’re like me, you’re likely to forget half the stuff you need to do, and if it weren’t for project management software, I might as well stay in bed.

To put it mildly, there are *a lot* of applications out there that help you track bugs and manage projects, and this article only looks as a handful of them. Although the general purpose of these web-applications are similar, there are substantial differences in the pricing models, features, and usability, and hopefully this article will help you identify an application that is right for you. Or, if you’ve never really thought about using one before, maybe this article can help show you why project management / bug tracking software is good to have around.

Comparing Online Invoice Software

Following up on an article I wrote a couple years ago on Free Online Invoice Software, I wanted to write a blurb about paid online billing software. My business has grown, and I was spending more and more time dealing with invoices. So it was time for me to actually pay for the software that pays me. Seems kinda silly doesn’t it? I was so uptight about spending money on software that actually pays me. So I spent a few hours with each of the programs below, and well… you can read about what I found.

  $$$/mo Users Clients Projects Invoices
FreshBooks $19.95/mo 1 (you), additional logins (e.g. for accountant) @ $10/mo (clients can optinally be granted viewing privileges) 25 ??? Unlimited
Harvest $12/mo 1 (you), additional logins (e.g. for accountant) @ $10/mo Unlimited Unlimited Unlimited
Invoicera $9.95/mo 1 (you), plus 2 additional logins 25 25 Unlimited
QuickBooks $12.95/mo 1 (you) + your accountant Unlimited (?) Unlimited (?) Unlimited (?)

* Sources: 1, 2, 3, 4


Freshbooks offers a very clean interface that made a lot of sense to me right off the bat. It was easy to add clients and recurring monthly expenses (holy %!**! I didn’t realize how much I was spending on server hosting!). It integrates right into my PayPal account, so when a client pays an invoice, POOF, that invoice automatically updates and marks itself as paid. I used to have to do that manually with BillingManager.

The price was a bit high for what I got, so I’m sorta waffling on that, but what really sold me on FreshBooks was the nice desktop timetracking software, ChronoMate. It’s $1/month more to use it, but I can clock stuff while working offline, then it syncs directly with my FreshBooks account, so I know (and my clients know) exactly how much time I’ve spent working on a project. Throw me a bone (affiliate link)

Harvest Invoices
Harvest Invoices

Harvest is a solid application, and they are actively developing improvements. The menu organization here was also very similar to FreshBooks and Invoicera.

Harvest Menu

I have nothing but good things to say about Harvest: this is really a well-crafted application, and its pricing and features offer a superb value: unlimited Clients, Projects, and Invoices for all plans. They offer some really nice integrated time-tracking features, so I’m eyeing this very seriously: the ChronoMate integration with FreshBooks is pretty good, but it has some shortcomings that Harvest doesn’t have. I have to give a big tip of my hat to Matthew Lettini (one of? their Designer) for his detailed responses to my questions. Harvest gets massive bonus points for its commitment to good communication and taking their customers seriously, so if you want to work with a company that works with you, I don’t think you could ask for more.


Invoicera also offered a really nice application. It too offered a very similar set of menu options, and it was very easy to navigate. I can’t think of anything wrong with this software.

Invoicera Menu
Invoicera Menu

It was easy to set up invoices, both one-offs and recurring. The expense management was a little bit confusing to me, but I got the sense that with a little bit more time spent using the software, it’d become really clear — they too were responsive to my questions about the software. The user interface was somewhere between Harvest’s and Freshbooks.

Probably the biggest draw here is what you get for the price: you and 2 additional users (e.g. your accountants) get logins for free with the default package. You have to pay for that with the other systems.


Originally I thought I would end up going with QuickBooks because I was already using its little brother: BillingManager. Wow… that was a bad assumption. All the simplicity and ease of use that was present in BillingManager was completely gone in QuickBooks… gone as in “scorched earth, salted ground.” The supposedly “automatic” transfer of data from BillingManager to QuickBooks was completely botched: half of my data from 2 years ago made it over, the rest… who knows. And nobody over there seemed to know what was going on. BillingManager was sort of treated like Intuit’s bastard child that nobody knew what to do with. It would have saved me time if they could have just deleted the partial data.

QuickBooks Menu
QuickBooks Menu

If you look at the menu closely, you can see that it’s WAY more complicated: QuickBooks offers features not offered by its competitors, but the price you pay is dealing with a wonky application and befuddled responses from the support hotline. To boot, most of the features that might justify this complexity (e.g. time tracking, integrations with online banking and credit card statements, and bill management) comes only with the beefier packages starting at $24.95/month.

The biggest waste of time with QuickBooks is that they offer NO email support and NO public ticketing system of any kind (one of their pages says they offer email support, but their support staff said they didn’t, so who knows what’s going on there… they don’t even know it seems). Compare the time it takes you to fire off a 2 line email identifying your problem with the software to the time it takes to wait in the call queue and finally get transferred to someone who might know what you’re talking about. That’s lost money right there: your time, wasted. It made it worse that I’m living abroad while trying to set this up, so figuring out the time differences of when I could call them, and then paying international calling fees to wait in their call queue is just poor. I wouldn’t recommend using QuickBooks unless your accountant demands it.


This was really close: pretty much a three-way tie in many ways between FreshBooks, Harvest, and Invoicera. Look at their menus: they are all very similarly structured. Honestly, I think that Freshbooks, Harvest, and Invoicera are all great products, and I would have been happy using any of them. QuickBooks is the only one that annoyed the piss out of me: having a site that runs on pop-ups and forcing all their support requests to take place over the phone were just nails in their coffin. QuickBooks may be the “industry leader”, but I think they’re ripe for unseating because their site and their software were just painful to deal with. I wouldn’t be surprised to see a comment on this post asking me to “please give us a call to discuss”, but meh… I’ve spent too much time on the phone with them already.

WordPress vs. MODx

There are a lot of Content Management Systems (CMS’s) out there, so I wanted to give a blow-by-blow analysis comparing two of them: MODx and WordPress. I feel oddly qualified to do so: Brian and I just authored a book on WordPress plugin plugin development (WordPress 3 Plugin Development), and I am a MODx Solution Partner who was invited to speak at the MODxpo conference in Dallas last year. I’ve used both flavors of MODx (Evolution and Revolution) and WordPress while building somewhere around 50 web sites over the past couple years, and I like both systems. I have even contributed a couple plugins for both systems (e.g. Custom Content Type Manager for WordPress). So after the urging of some friends and colleagues (like Kris), I’m organizing my techno-ramblings into a coherent article.

I’m going to walk through a series of areas and compare and contrast both how both CMSs work in those areas. The comments here apply to WordPress 3.x and (mostly) to MODx Revolution, but MODx Evolution is mentioned where appropriate.

*Source: WordPress requirements, MODx requirements

If the requirements for MODx Revo look insanely detailed, ask yourself this: “do you really want to be guessing whether or not your server will support a given app?” MODx Revo does a pretty good job of testing for the necessary requirements during installation, so you don’t have any unexpected surprises.


WordPress offers its “famous” 5-minute install, and I give them credit where credit is due: WordPress is a simple web app to install, but to be fair, installing MODx Evolution is also very straightforward.

MODx Revolution has beefier requirements, and it’s far more likely you’ll run into troubles setting up your webserver permissions or PHP extensions (e.g. PDO). Moving a Revolution install to a new server is also a tricky operation that requires some patience (see this how-to).


In short, WordPress and MODx Evolution are easily installed on practically any web server that supports PHP and MySQL. MODx Revo takes longer to install and configure and it requires a beefier server.


Hands down, MODx offers the gold standard in templating. Expression Engine is a healthy second place, but only in my days of doing Perl development with the venerable Template Toolkit did I encounter a templating system that followed good MVC architectural principles as well as MODx.

What does that mean? It means that if you’re a front-end designer who likes to roll your own HTML and CSS, then MODx will grant you total freedom to implement the designs you want, whereas WordPress may result in headaches and holes punched in your walls (no comment on the convoluted mess that is Drupal and Joomla templates). I’ve posted previously about creating templates in MODx Evolution and how to import existing layouts into MODx Evolution, and the process in MODx Revolution is nearly identical (the only difference is the format of the placeholders).

In MODx, you can easily have multiple templates (i.e. layouts), and use any one of them for any page. In WordPress, the ability to use a specific template is possible only with pages, not posts. The thing that really gives me convulsions is understanding how WordPress formats its special pages, e.g. a category page, or an author page. See the image below as a reference for how WordPress formats page requests.

WordPress Template Hierarchy
WordPress Template Hierarchy

See the official WordPress docs for Template Hierarchy for more information. I honestly have a hard time fathoming that this is the solution that actually got implemented… what other crazy ideas were on the drawing board?


If having a specific HTML/CSS layout for your site is more than a “nice-to-have”, then MODx will save you many hours; the time to rework layouts in WordPress can be considerable and some of the PHP hacks are not trivial, whereas MODx templates are easy to create, modify, and maintain.


MODx offers nearly infinite menu flexibility through use of menu-generating PHP Snippets, primarily WayFinder, but it’s not aimed at the average user. WordPress has a built-in GUI for creating menus, but I have experienced some bugs with it when using custom content types. Your WordPress theme may not support more than one or two menus, so in the end you may end up writing some code in your tmeplates (e.g. using my Summarize Posts plugin) so you can list the posts that you want to see.

In a nutshell, WordPress offers an easy GUI, but if you need more customization MODx’s flexibility here is far greater.


WordPress has a huge number of user-contributed plugins available, whereas MODx has relatively few. The sheer number is not a good comparison, however; I downloaded and tested hundreds of plugins in the process of writing my WordPress book, and the number of plugins that are unusable due to sophmoric errors or plain-old bad coding is huge. I estimate that at least half of the plugins in the WordPress repository are unusable, and perhaps only a tenth of them are worth using. There are crufty plugins in the MODx repo to be sure, but the playing field is more even than you might think.

The real difference here comes when you have to write your own code: MODx is a lot easier to work with with a shorter learning curve for a majority of code, whereas learning the ropes of WordPress plugins requires more guidance (hey, did I mention we wrote a book about that?).


This is an area that is hard to discuss unless you’re a geek, but in a word, MODx offers a robust and well-architected MVC framework under the hood that can make writing custom plugins (Snippets, manager pages, et al) a breeze. The work done by Jason Coward and Shaun McCormick is really astounding.

Some of the limitations to WordPress are really staggering: it is basically a stateless application, so by default it does not use sessions, and nearly all of its API functions exist as procedural functions in the main namespace, so naming collisions are a big concern when authoring plugins. This makes certain functionality damn near impossible in WordPress. For example, creating a WordPress application with a login portal and access to custom data models would require an enormous amount of time. Even accessing WordPress’s posts and categories is difficult at times; I basically had to rewrite core WordPress functionality with another plugin (Summarize Posts) just to get the menus and summaries I needed for one recent site.

Another severe limitation is WordPress is that all extensions to the core occur via plugins that are triggered by system events (confusingly they are loosely categorized into “actions” and “filters”). This construct can be awkward at times, and the WordPress architecture is showing its age as the number of events exponentially increases, whereas the amount of documentation for them continually wanes. Realistically you can get WordPress plugins to do just about everything you need using only a handful of events, but debugging someone else’s plugins is a nightmare: there is no centralized location listing which events are being hooked into, and new events are often created and executed on the fly. Debugging WordPress plugins is like Alice’s trip down the rabbit hole: majorly trippy,and you don’t know if you’ll ever come out.

User management is another area where MODx dwarfs WordPress: Revolution can handle totally granular control of permissions, but it is admittedly overly complex for 90%+ of use cases. Evolution offers a much more sensible permissions scheme that covers most use cases.

MODx offers much more sensible implementations of custom code: like WordPress it uses event-driven plugins, but it also uses custom PHP snippets which can be placed anywhere on a page or in a template.

Another impressive feat is how MODx Revolution has abstracted the database into a separate coding layer — that means it is relatively easy to interface with custom database tables (or even to other database engines) using code that is completely database agnostic (support for SQLite and PostGREs is in the works). That’s some seriously geeky stuff that has kept me awake at night trying to comprehend how they accomplished that. MicroSoft has even worked directly with the MODx team because MODx’s architecture is flexible enough that it can run on an all MicroSoft stack (i.e. IIS and MS-SQL). I can’t think of a single other system that switch-hits as well as MODx.


If the site you are building is more of a web application that requires a lot of custom coding, go with MODx; the level of maturity in the underlying MODx framework is light years ahead of WordPress, but be advised that the coding in MODx is sometimes so advanced, it takes a very senior developer to understand what’s going on. If you decide to do a more serious application-type-project in WordPress, be sure to allocate extra time to augment or rewrite the core code. If you’re doing basic extensions or variations of a simple site/blog, then WordPress plugins can do that pretty well, so don’t overcomplicate things.


WordPress offers a clean manager dashboard for its administrators which relies on the jQuery JavaScript library to provide AJAX functionality and smooth user experience. It’s pretty easy to find your way around.

MODx underwent a huge change in its manager dashboard between Evolution and Revolution, and the Revolution dashboard is overwhelming for many. Evolution’s dashboard is cleaner and snappier.

MODx Revolution’s manager dashboard is still being optimized. It’s based on ExtJS. For those of you not familiar with ExtJS, it was based on YUI (the Yahoo User Interface library), and it offers some fatastically powerful features for building interfaces for web applications. My only complaint with it is that it’s heavy: the MODx Revo dashboard can take a long time to load, and sometimes clicking on buttons and links feels unresponsive.

Do not make your decision about which system to use based on the dashboard alone — that’s like marrying a girl for how big her tits are. I know some clients who have loved and hated the dashboards in both systems. Again, MODx offers more flexibility if you want to change the dashboard behavior. The big difference here is simple: WordPress gives you a super clean view of your posts based on time whereas MODx gives you a hierarchical view of your posts.


Everybody wants a blog, just like everybody wants a shiny new car. Authoring blogs has been a core competency of WordPress, and they get massive props for making them very simple to setup: out of the box, you can get a blog up and running with integrated tags and categories and comments within minutes. It’s really what WordPress is all about: blogging. WordPress even has some nice security features in place with its Akismet spam filter.

Contrary to some of the on-line murmurings out there, both versions of MODx can run blogs, but until MODX 2.2, the process to set them up was painfully laborious in comparison. The Articles extra for MODX gives you a quick and easy blog — it can even import your posts from WordPress, so the gap between the two systems is closing quickly. The only thing it doesn’t do as well as WordPress right out of the box is its taxonomies (tags and categories): you still have to do some configuration to get those configured how you want them, but as the docs say:

“MODx Revolution is not blogging software, but rather a full-blown Content Application Platform, it doesn’t come pre-packaged with a cookie-cutter blogging solution.” 


If your priority is to get a blog up and running as quickly as possible, and you have few requirements for supporting any other content, then WordPress is the way to go. Starting with MODX 2.2, however, you can use its “Articles” extra, which gives you simple blogging functionality, with many of the features available to WordPress.

Custom Content (CMS functionality)

If blogging is where WordPress shines, then CMS functionality is where MODx clearly has the upper hand. WordPress does support custom fields for its posts and pages, and in version 3.x, they support additional “post types”, so finally WordPress is getting some traction as a CMS, but it’s still a bit of a toy in comparison to MODx.

One of the biggest problems with WordPress as a CMS is its lack of support for sensible custom fields: for each post or page, you have to manually add the same custom fields over and over again, and by default, the custom fields are always simple text fields. I have attempted to rectify this in my Custom Content Type Manager plugin, and my plugin does a lot to give WordPress CMS capabilities, but it still represents a series of awkward workarounds that stretches the WordPress core nearly to its breaking point.

One related area here is how MODx can manage and serve static files via what MODx calls “Static Resources”. This is a great way to enforce permissions on viewing, streaming, or downloading static files (e.g. PDFs or Flash movies). WordPress just flat out can’t do that.

Although MODx offers greater flexibility, WordPress’ integration is a bit cleaner for the manager user (it’s a holy pain in the ass for the developer, but if you download my plugin you should avoid this unpleasantness). When WordPress registers a new “post type”, you get a nice menu icon in your dashboard and it’s really clear to the manager that he/she is adding a new post, page, or movie (etc). For example, if you want to add a movie post, you’d click on “Add Movie”. It’s really quite logical. In MODx, this same type of distinction occurs at the template level. Architecturally, this makes sense, but it’s confusing for the manager user, because it may not be at all clear that they need to add a “normal” page (i.e. resource), and then choose to use the “movie” template. I’m planning a MODx plugin to help rectify this UI “wart”.

If you have to display multiple types of content on your site (e.g. an eCommerce site), then MODx offers far greater flexibility, but it does take longer to configure. If your CMS requirements are simple and you don’t need to worry too much about customizations, then WordPress can do that very well and very quickly.


SEO is the an cyclical buzz, and at the moment, a lot of SEO guys are hailing WordPress as the holy grail of search-word wad-shooting. To be blunt, I think SEO is largely an over-hyped crock of crap. If you build a well-structured site with good content, your pages will show up in search results: if there is a site out there with awesome content that is not showing up in relevant search results, I have yet to see it. Search engine optimization is often a pseudo-science practiced by get-rich-quick marketeers who are convinced that they can turn lead into gold by over-hyping a site with various gimmicks. 90% or more of SEO should have to do with creating good content, and perhaps the last 10% of your efforts should go into polishing your site. It can be used to improve search results, but it tends to fail when you try to make search results come out of thin air. Too often I have seen companies do this the wrong way around: they spend 90% of their time publicizing a site that is a vapid cesspool instead of spending their time making a site that’s worth visiting. At best, SEO techniques are constantly changing as Google updates and refines their indexing algorithms. If you optimize your site today and Google farts tomorrow, all of your work may be for naught. Do your due dilligence, but it’s just not worth spending inordinate amounts of time tring to beat Google at their own game.

Rants aside, both systems offer ample ways to do search engine optimization. Assuming that you have good content, the rest of the process boils down to having well structured HTML (which relies on a solid templating system), and the ability to effectively index your pages. WordPress offers built-in taxonomies (categories and tags) for flagging your posts, and MODx can be set up to do this rather easily by using an Auto-Tag custom field (a.k.a. a MODx “Template Variable”).

MODx offers a much more flexible system for generating URLs (basically you can use any URL you want for any page). WordPress does offer flexibility here, except for its special pages (e.g. category listings or author pages).


Comparing SEO features between MODx and WordPress is a moot point: both systems allow you to adequately structure your content and your site.


No system is 100% secure. MODx has had relatively few serious exploits; WordPress has had many, no doubt due in part to its popularity. For what it’s worth, I have had WordPress and MODx Evolution sites hacked, but not yet a Revolution site. It’s hard to quantify how secure an application is… I’d love to see the detailed forensic results of a penetration test against default installations of both CMS’s. In general though, the WordPress architecture is primitive and more ripe for being hacked: it’s more difficult to lock down spaghetti code. WordPress also offers many more plugins, and the plugin authors tend to be less experienced, so their code is more likely to have security holes.

There are many fingerprinting utilities out there that will attempt to locate known weaknesses in plugins, and WordPress is more easily fingerprinted; MODx Revo allows you to change default locations for the MODx manager or to even remove it from public view altogether. There are some discussions in the MODx Forums about how to harden MODx, but I haven’t yet seen a detailed how-to on how to eliminate the most common attack vectors. There are also good posts out there for hardening WordPress.

I reported a nasty vulnerability in phpThumb that affected MODx and numerous other CMS’s (phpThumb is a popular image manipulation library), but the MODx Revo architecture prevented the exploit from succeeding on Revo (good job to Shaun and Jason for architecting the connectors in the way they did).


I feel that MODx Revolution is probably more secure, but there are no guarantees when it comes to security. No system is bulletproof, so you best have redundant backups on hand and follow the recommendations of Basic Web Security no matter which system you’re on.


This is another area that is pretty black and white in my opinion: WordPress support sucks. Although WordPress is more popular if you look at the numbers, you wouldn’t know it if you post questions in the WordPress Forums. I have rarely gotten any useful answers (if I got answers at all): anything beyond simple inquiries tend to go unanswered, leaving me alone in the dark reverse-engineering damn near everything.

My other gripe with WordPres is their weird distinction between and You can host your blog at, and then you get more support, but it is effectively software as service: you can’t upload plugins and you can’t modify code, so the interface suddenly becomes a bit like BlogSpot.

By contrast, the MODx Forums are full of helpful people. It’s a great place to be: it’s not uncommon to get responses from the core team on almost any level of inquiry, from trivial to cerebral meltdowns. There are some superstar participants, such as Susan Ottwell and Bob Ray, who have both contributed immensely helpful posts and tutorials on how to use MODx. MODx also offers commercial support; it’s still in its infancy, but for a yearly fee, you can get access to a kind of “MODx hotline” and get help resolving MODx issues on your sites.


In the same breath as support, I must mention documentation. In general, documentation for both systems is lacking, in some areas painfully so. While using WordPress, I have often I have searched for hours trying to find a way to do a certain thing, only to end up grepping through the code base and deciphering the raw code myself. Frequently the official documentation has holes or in some cases, it’s just plain wrong. The best resources for some advanced WordPress features are blogs written other developers.

MODx’s documentation is also frustratingly AWOL on a number of topics, but least the MODx code base is integrated with a standard documentation publishing system so if needed you can see for yourself how the functions are structured without having to grep through the code base. The vibrant MODx forums fill in a lot of the holes in the documentation, and that’s a huge benefit for any open-source project.


If you need support for your site, especially guaranteed support, then only MODx offers a paid support service; WordPress doesn’t offer a paid support option.


WordPress can handle a huge number of posts, but it does get bogged down with a large number of pages, and there are lots of whisperings about this (e.g. here). I suspect it has to do with WordPress’ convoluted templating system (see above), which makes me wonder what the limits are on custom post types.

MODx Evolution suffered from a limit of approximately 5000 resources (in MODx, pages and posts are types of resources), but that limit has been corrected in an upcoming release thanks largely to the efforts of Charlie over at

MODx Revolution has no such limits: it offers a great built-in caching system that allows it to serve pages very quickly. It has been benchmarked as twice as fast as Expression Engine (see this blog post).

More importantly, MODx Revolution was built with scaling in mind: it stores session data in the database, so it is easily deployed on load-balanced servers. This is hugely important if you are building a site that might one day get massive amounts of traffic; WordPress can be deployed like this, but such usage is not generally anticipated. I don’t know of many large commercial sites running WordPress (in fact, I only found one:


MODx is by far the more mature option here if you anticipate building a large site.


I do like both systems, and I use them both daily. WordPress has a much lighter footprint and is easier to use for a large number of use-cases: if you just need to get a site out the door fast, then WordPress is really hard to beat. WordPress is plug-and-play for just about everything and that saves you hours of setup time, so it can be the right solution for a majority of sites. But the more customizations you require (particularly in scripts or in layouts), then the more appealing MODx becomes: WordPress has thousands of plugins available, but if those aren’t meeting your needs, I’ve found certain types of customizations to be extremely difficult in WordPress whereas most often, MODx handles them with ease. Doing things like building web applications with strict formatting requirements is much easier in MODx because it’s built more as a launchpad for customizations: it’s really more of a content management framework (CMF). MODx Evolution is the best system I’ve used for building small to medium sized informational/brochure sites, WordPress rules as the blogging king, and I’ve been very impressed with how easily I can build web applications using MODx Revolution. There isn’t one tool that’s right for every job; the more projects you complete, the better idea you’ll have as to which system will accomplish your requirements more easily, and hopefully this article helps you spot more of what each system is good at.

Releasing New Versions of your WordPress Plugins

If you are a WordPress plugin developer, then this post is for you. There is very little documentation on how to effectively use the WordPress Subversion repository, and the repo architecture is critically flawed in its structure making “kosher” usage seem entirely buggy. Worse yet, the support in the WordPress forums is practically non-existant. For a more thorough explanation of this process, see our book on WordPress 3 Plugin Development Essentials, which features an entire chapter on dealing with SVN and the WordPress repository.

Below is the short summary of what is presented in the video.

How to release updates to your WordPress plugin (quickie version)

  1. Make the updates to your code, fix any errors, add new features.
  2. Update your plugin’s main file (the one with the information header) so that it references the new version of your plugin, e.g.
    Version: 0.5
  3. Update your readme.txt file to describe the changes you have made, but DO NOT change the Stable Tag. This number must point to an existing directory inside your repo’s tags directory.
  4. Save your files, then commit your changes to the SVN repo, e.g. svn commit . -m "My new version is ready"
  5. Tag the new version using the SVN copy command to copy the trunk new a new numbered directory in tags, e.g. svn copy
    Remember: the tagging operation is just a copy operation.
  6. By performing the tagging (i.e. copy) operation, a new directory has been created inside the tags directory. So only now can you safely update your readme.txt file’s Stable Tag, e.g.
    Stable tag: 0.5
    That number acts as a pointer to the corresponding folder inside of the tags directory (it would point to in this example).
  7. Commit your changes to the readme.txt file. This will ensure that the Stable Tag attribute points to the newly created version: svn commit . -m "Updating the stable tag"
  8. You should be done now, but the WordPress SVN repository has been so problematic…. keep an eye on your plugin’s download page and verify that the changes get picked up. The changes should be picked up within 15 minutes or so… if they don’t get picked up, look at the downloaded zip file carefully… does the link say one thing but the name of the zip file says something else? It’s easy to mix things up, so if you get stuck, try reviewing the steps here.

How to release updates to your WordPress plugin (Long Version)

Ok, that was too quick? Well, we left out some important geeky points. The way WordPress’ download page works is that it looks at the readme.txt file at the HEAD of the repo, and then it follows the value listed there for Stable tag. If the Stable tag lists version 0.8, then the information from tags/0.8/readme.txt is used to generate your plugin’s information page and the files in tags/0.8 are packaged up into a zip file and that’s what downloads when the user clicks the download link.

Can you see the problem with this setup? Normally, when you tag a directory in SVN, that copy is treated as a read-only reference, but in this setup, it is frequently easier and less prone to errors for you to go into the tags directory and make your edits. This is normally a bit no-no for version control!

So the safer way to do this is to develop your plugin normally inside the wp-content/plugins directory and submit to the trunk as you normally do. Once you’re ready to publish a release, go to a new folder somewhere on your hard drive and checkout your ENTIRE project, trunk, tags, and all. Then you can do your tagging operation locally, e.g. svn copy trunk tags/0.9, and that will give you a new directory. You can update that directory’s readme.txt file and your plugin’s information header, then commit all of your code (trunk and all tags folders).

Hope that helps los dudes.
