Enabling VPN split tunnel with NetworkManager

I've been using NetworkManager for some time now, and appreciate how easy it makes both connecting to wifi as well as VPNs. That said, I've had an issue with it that I only resolved today.

When working from home, I prefer to use a VPN split tunnel setup -- I'm behind a firewall all the time, and it's useful to be able to run virtual machines while still connected to my VPN (e.g., when doing training or webinar sessions). However, I noticed some months ago that this wasn't working. I assumed at first it was a change in our network setup, but others reported that the split tunnel was working fine. It's been particularly problematic when on IRC -- if the VPN drops, I lose my IRC connection, meaning I have to re-connect and re-claim my nick.

So, I did some searching, and found an interesting setting. In NetworkManager, "Configure..." then "Edit" your VPN connection, and navigate to the "IPv4 Settings" tab. Once there, click the button that says "Routes..." and select the checkbox next to "Use this connection only for resources on its network". Press Ok to close the dialog, then "Apply" to exit out of the VPN configuration. Re-connect to the VPN, and you should be all set.

Note: this will only work if your VPN server is configured to allow split tunnels. Additionally, only do so if you are behind a firewall. Practice safe networking.

Cloning the ZF SVN repository in Git

I've been using Git for around a year now. My interest in it originally was to act as a replacement for SVK, with which I'd had some bad experiences (when things go wrong with svk, they go very wrong). Why was I using a distributed version control system, though?

Blog Backlog

Several people have pointed out to me recently that I haven't blogged since early May, prior to attending php|tek. Since then, I've built up a huge backlog of blog entries, but had zero time to write any of them.

The backlog and lack of time has an easy explanation: my change of roles from Architect to Project Lead on the Zend Framework team. While the change is a welcome one, it's also been much more demanding on my time than I could have possibly envisioned. Out of the gate, I had to finish up the 1.8 release, and move immediately into planning and execution of the 1.9 release -- while learning the ropes of my new position, and continuing some of my previous development duties. Add a couple of conferences (php|tek and DPC) into the mix, and you can begin to see the issues.

Autoloading Doctrine and Doctrine entities from Zend Framework

A number of people on the mailing list and twitter recently have asked how to autoload Doctrine using Zend Framework's autoloader, as well as how to autoload Doctrine models you've created. Having done a few projects using Doctrine recently, I can actually give an answer.

The short answer: just attach it to Zend_Loader_Autoloader.

Now for the details.

Speaking at php|tek

I announced this earlier in the year, but for those that missed it, I'm speaking at php|tek next week.

Speaking at php|tek 2009

I'll be co-presenting a workshop entitled Practical SVN for PHP Developers along with the lovely and talented Lorna Jane Mitchell. In a way, it's a continuation of the unconference session we did together at ZendCon08, and will provide much more in-depth information on the subject -- including how to create and organize your repositories, branching and tagging strategies, how and when to commit, as well as more basic usage of subversion for day-to-day use.

Creating composite elements

In my last post on decorators, I had an example that showed rendering a "date of birth" element:


<div class=\"element\">
    <?php echo $form->dateOfBirth->renderLabel() ?>
    <?php echo $this->formText('dateOfBirth[day]', '', array(
        'size' => 2, 'maxlength' => 2)) ?>
    /
    <?php echo $this->formText('dateOfBirth[month]', '', array(
        'size' => 2, 'maxlength' => 2)) ?>
    /
    <?php echo $this->formText('dateOfBirth[year]', '', array(
        'size' => 4, 'maxlength' => 4)) ?>
</div>

This has prompted some questions about how this element might be represented as a Zend_Form_Element, as well as how a decorator might be written to encapsulate this logic. Fortunately, I'd already planned to tackle those very subjects for this post!

Speaking at DPC (again!)

I'm thrilled to once again be speaking at the Dutch PHP Conference.

Like last year, I'm giving two sessions; unlike last year, these are going to be more advanced. I noticed last year both in terms of audience participation as well as in speaking with attendees that I'd be able to step it up a notch were I to return.

Rendering Zend_Form decorators individually

In the previous installment of this series on Zend_Form decorators, I looked at how you can combine decorators to create complex output. In that write-up, I noted that while you have a ton of flexibility with this approach, it also adds some complexity and overhead. In this article, I will show you how to render decorators individually in order to create custom markup for your form and/or individual elements.

Zend Framework 1.8 PREVIEW Release

By the time you read this, the Zend Framework team will have released a preview release of 1.8.0. While the final release is scheduled for later this month, this release represents the hard work of many contributors and shows off a variety of powerful new components.

If you're a Zend Framework user, you should give the preview release a spin, to see what it can do:

From the inside-out: How to layer decorators

This marks the second in an on-going series on Zend_Form decorators.

You may have noticed in the previous installment that the decorator's render() method takes a single argument, $content. This is expected to be a string. render() will then take this string and decide to either replace it, append to it, or prepend it. This allows you to have a chain of decorators -- which allows you to create decorators that render only a subset of the element's metadata, and then layer these decorators to build the full markup for the element.

Let's look at how this works in practice.
