Sometimes you’ll need a (slightly) better C# WebClient that’s able to store/retrieve cookies, prevent redirects or retrieve the HttpStatusCode of a request. I’ve created a small class that facilitates these features.

Doing calculations on Knockout data-binds might result into a “Uncaught SyntaxError: Unable to parse bindings” error. Solution: use an anonymous function!

Do you need to inject jQuery or are you writing a bookmarklet? This script will inject the right version, taking IE8 and lower into account.

Knockout MVVM + offline persistence with localStorage or . Automatically bind the model to offline storage. This script leverages both systems.

While working with the Chrome Developer Tool, I’ve discovered that you can retrieve the XPath of a selected node. But… it only works in Chrome. So what about other browsers? What about jQuery? What about querying documents that resulted from an AJAX request?

MP3s are everywhere and back in 2014 I finally had a phone with enough storage to store a decent amount of them. I use MediaMonkey to add high resolution album covers and to rename the files in a predictable format: Artist – Album – # – Title. The only thing I was missing was a simple way of creating a M3U playlist: PowerShell to the rescue!

Sometimes you need to test if two files are the same. As files are getting larger, your scripts will take longer, so we need to look into performance. In this article, I’ll show how to compare two files using a buffered approach in PowerShell.

Yesterday I was working on a bit of code that had to read the XMP meta data from a file. It is not located at a certain position, so I had to scan the file. XMP, being plain XML, can be found by simple string matching. After some searching I’ve found many solutions that read the entire file into memory and perform a regular expression search or a string comparison. That’s not going to work for me, because I have files that are +100MB! So I wrote some code that does a search that performs.

PowerShell is very similar to .NET, so it is no surprise that it is very popular with .NET developers. It is a language for writing scripts, so you might encounter some unexpected situations. I had this experience when I tried to parse some HTML with PowerShell: I could not get the replacement with regular expression groups to work! It turned out that my .NET knowledge was working against me…

As a developer, I love to solve common string problems with regular expression. Sure, they are sometimes hard to read, but you can do so much with such a small expression! It is nice that many languages have support for them, but sometimes it feels like every language creates its own dialect. Let’s look at the difference between regular expression groups in .NET and JavaScript.
