Need to store up some items and process them en masse in a cron job? That’s a perfect use case for the Queue API (for Drupal 7+) or the drupal_queue module (the backport for Drupal 6).

Concrete example: One of our consulting clients was using a synchronous webservice for their retail store locator. We needed to create a form where store owners could change whether they’re listed in the store locator. When a store owner submits the form, should she have to wait around while our site sends her change to the store locator webservice? We didn’t think so. So we decided to use Drupal’s Queue API, which lets us save up all the store owners’ changes and send them to the webservice in a batch.

Here’s a simple example of adding items to a queue in a form submit handler and processing them in the next cron run. [more...]

In not-so-recent news, Drupal migrated the drupal.org project repository from CVS to Git in late February, 2011. My experience with Git previous to this has been as a user fetching source code of x.org, mesa, dri, and other various Linux and Unix projects.

As a user, not a developer, I found the Git work flow confusing. I did not need to make local commits and it was hard to wrap my head around bringing in changes from multiple remote repositories.

As a PHP developer, I first grasped the work flow at Columbus GiveCamp 2010 when I needed to make a github account for the branch of the Audio module we hacked on. As well, some Ruby guy had a nice Git work flow diagram, which I promptly forgot all about until the not-so-recent event above. [more...]

It’s a wonderful fact about the world that humans have thousands of living languages. And a wonderful fact about many software development environments that they provide ways to create versions of applications localized into the most common of those languages. But before localization (or should I say world-readiness) sweeps you off your feet, let me tell you about some unexpected difficulties with Kineme’s first localized application. [more...]

Cool things I learned about at Drupalcon DC include (but are not limited to) the following:

• There is a Drupal 6 theme starter app whose maintainer is constantly improving it.
• Usability studies have proven that I am not the only one who couldn’t figure out WTF to do with the welcome screen on my first Drupal install.
• A lot of the modules that seem like they should be in core but probably won’t be in Drupal 7, are left out because Token is unlikely to be included and many of them rely on Token.

As usual, more coming…

I can positively affirm that the free tee-shirts given out with DrupalCon 09 registration are quality. The medium size fits me perfectly and the cotton is nice and soft and thick. Overall very wearable. Caveat: they’re not pre-shrunk so they will shrink.

I have a lot of actually relevant info to post but that will have to wait. Topics will include:

• Theming tips and best practices
• Awesome stuff (eg. fields!) that will be built-in to Drupal 7
• Awesome stuff that won’t be in core in Drupal 7, and why it won’t (Hint: if it depends on something that won’t make core, it can’t go in core either)
• Some other stuff.

Overall it’s been enjoyable and packed with information so far. I only wish I could go to more sessions.

There are a few functions used to zero out memory on most unix variants. memset(), bzero(), and calloc() are all a few such functions. calloc() isn’t very useful for clearing already allocated memory, so it won’t be appearing much more in this article. However, the other two are somewhat more interesting than meets the eye. [more...]

In the wee small hours of this morning, Kineme Interactive Media released its first commercial product, QuartzCrystal.

QuartzCrystal is an offline renderer that turns Quartz Compositions into portable QuickTime movies. It supports 3rd party plugins, as well as patches that do not work in safe-mode-only environments (such as QuickTime Pro). It also supports software scene antialiasing, so if you have a Mac with plenty of RAM and a hard-core video card, you can make spectacularly beautiful renderings of your plugins, effects, and compositions.

Beside QuartzCrystal, the only other product that renders and encodes compositions to movies is Apple’s own QuickTime Pro, which doesn’t support plugins, unsafe patches, or antialiasing.

Last summer Kosada purchased a MacBook Pro for the president of one of Kosada’s consulting clients. It’s been a great improvement over the old Dell laptop he was formerly using, and, though he was initially worried about whether he’d be able to grasp the new UI, he seems to have picked it up quickly, and he reports that he’s been loving it.

But this morning he called me with a rather odd problem:

“I hooked up my Treo and started syncing it, then walked away for a few minutes. When I returned, the screen was covered with a bunch of squares, and I can’t do anything.”

People like their applications to work. Even better, they like them to work, even when things change. For the WinTel world, this isn’t a big deal (Vista aside ;), because the underlying CPU architecture hasn’t really changed, from a program’s point of view, in the past two decades. Unless you have a weird program that’s designed for AMD’s 3DNow! instruction set and you switch to an Intel CPU, or perhaps an application designed for a more esoteric old SIMD architecture, your application should run just fine (as long as your Operating System is ok with it).

Mac OS X doesn’t have the luxury of working on the same underlying CPU though, so things need to be handled a little bit differently. The solution Apple came up with was [more...]

Good morning gentle readers. I opened up my craptop this morning to witness the struggles of what seemed to be a laptop battling cancer. No, this was not another case of opteron cancer. Instead I found that Windows, unable to cope with my Cisco Aironet 350 wireless card, was creating network connections one after another in the system tray. [more...]
