It was at that moment I decided to make a go of it with Linux as my sole operating system. After nearly 2 years of tweaking, making mistakes, fixing those mistakes, and then making even more mistakes, I finally feel qualified to give you advice.

In Grails: A Quick-Start Guide, we have a task list to help TekEvent organizers and volunteers keep track of what's left to be done for their event. It's pretty handy, but it could be a bit easier to use. Specifically, it would be great if we didn't have to click on a task to open the show view and then click again to edit it, just to mark a task as completed. What would be really nifty is if we could mark a task as completed by clicking on a simple checkbox. And it turns out that Grails provides an Ajax tag that's just what we need.

We can use mysql_connect and mysql_select_db functions to create our connections. For closing the connections there is mysql_close function. These are basic functions of managing connections in PHP. There are also a lot of classes made by developers for free.

I want to share very useful in my opinion code snippets for WPF developers. Most of they were created my friend - Dmitrij Zakharov. Moreover I want to add a short description to each snippets. Note: The Code Snippet Inserter inserts a code snippet at the cursor location, or inserts a surround-with code snippet around the currently selected code.

In here, we will discuss a few method that we can use to disable Wordpress admin menu from displaying and accessing by valid users.

Closures are reusable code blocks in Groovy. The code of the closure is executed against the delegate of the closure. By default the owner of the closure is the same as the delegate, but we can change this. We can define which object is the delegate for a closure, so we can change the object the closure is executed for.

This post shows how to export files (like CSV, Excel) to desktop in a GWT based webapp.

Google Translate is a new tool that could help visitors understand your website no matter what language they speak. SitePoint looks at whether it’s great or gibberish.

In my last blog post I have covered the new Silverlight 4 Webcam API and provided a demo that used my edge detection pixel shader to create a nice real time webcam effect. In this post I make an extended version available which can save webcam snapshots as JPEG files and I also discuss some limitations of the webcam API's built-in CaptureSource.AsyncCaptureImage snapshot method. Furthermore I will give some ideas on how to build a Silverlight 4 video chat / conference application on top of the provided JPEG capturing and encoding code.

When someone asked my former manager David Treadwell what he did on a daily basis his answer was “Go to meetings and delete email”. Unfortunately that often describes my life as well. It is always challenging to manage your time. I want to ensure I’m spending enough on technology, people, customers, etc.

Yesterday I showed how we can map some of the Rx operators to an API which looks more like the F# base classes. Today I wanted to use these mapped operators in a WPF-application written in F#.

Have you ever wanted to give the user the ability to drag a file from you desktop or file explorer onto your Silverlight application? Well, up until now you couldn’t. What’s that sound? It’s a bird… it’s a plane… no, it’s Silverlight 4 Beta. Yes, Silverlight 4 Beta is coming to the rescue and giving you the ability to have your Silverlight application act as a drop target. And it is so easy to do. Observe.

Before Silverlight 4 if you wanted to dynamically add ellipses (the commonly used … to show that the sentence continues), you have to invent your own implementation which usually involves creating your own control that wraps a text based control and then manipulate the text inside based on the size. Similar to what Robby Ingebretsen had to do here.

So, by now you should have heard that Silverlight 4 Beta was released at PDC 2009. One of the most interesting and fun features included in the release is the ability for you to access a users webcam and microphone. Even a fellow ElegantCoder wrote a short post on it. But I wanted to go into a little more detail. So I am going to show you have to access a list of webcams and microphones, capture video, and then take pictures and show them to the user. But, before I can show you how to use them, you have to have the Silverlight 4 Beta framework installed.

The following steps explain how to serialize any .NET object into a JSON string. This tip uses the .NET 3.0 Framework. You'll find this capability particularly helpful in applications that use AJAX to pass objects from the server to the client code.

Many Spec Explorer users have asked the question of how and when to choose between static or instance-based at the time of creating a model. The Base Solution Wizard (Visual Studio File menu -> New -> Project… -> Visual C# -> Spec Explorer Base Solution) shortly explains in its second step the difference between these two kinds of models, while leaving the choice to the user

Marcel has been posting some interesting articles on using PowerShell to generate the MD5 hashes of files. Now, an MD5 hash of a file is just an array of bytes. Typical hashing programs display this in a more friendly manner:
