RadioduinoWRT Today I want to present you one of my larger craft projects. This time it is not just about software, but also about the associated hardware. What is it? A web radio!
I like to listen to internet radio stations, but I didn’t want to run my pc only for listening to webradios. Connecting my phone to my stereo either wasn’t a solution, since I’d rather wear this with me, because I don’t want to run for each SMS / Whatsapp message to the music system. And because I always like to tinker, it was obvious to build a web radio as a standalone device myself.
As this article has become a bit longer, there is a brief overview of the following sections of the article, so that everyone can quickly find what he looks for.

How to pixelate images using Javascript

Today there is again a bit of Javascript code. The exact topic is about how you can pixelate images via Javascript. This has both advantages and drawbacks, which I would like to briefly point out once below.
Advantages:

Pixelation can be done dynamically (Manual effort in your graphics program falls away. Graphics must not be known beforehand.)
The computational power required is outsourced to the client side. In contrast to a server-side solutions (eg using PHP & Imagick), the computational load is distributed to the users. This helps to keep the server load low, if you have a lot of visitors.

Disadvantages:

The pixelation should be used rather as design or graphic effect, since the data is only sent not pixelated to the client. So if you really want to hide faces and picture information the pixelation still needs to be done before delivery […]

ebay_logo Today it is about eBay. Specifically, about how you can add as many pictures as you like into your auction description for free. So there will be no additional costs, such as it would normally be the case, when you use the image features of eBay. Thankfully eBay gives us almost everything that is needed to add free images to our auctions.
To better explain the procedure, I created a fictitious offer on Ebay. Who does not like to read, of course, can also scroll to the end of the article and watch the whole explanation as screencast. And here’s how it works:

How to set up a PERL development environment on Windows with Eclipse

Posted by Raffael on 10/25/2013 Posted in Perl, Tutorials, Windows 7, Windows 8 Tagged Activestate, Activestate Perl, Eclipse, EPIC, EPIC Perl, Perl

As I shall deal, due to the university, the next six months with Perl, a appropriate IDE was needed. And because there were not given any installation instructions at my university, I have written down in the following, how you can set up a viable development environment for Perl scripts on Windows.
After reading this article you should be able to write Perl code using the IDE “Eclipse”. This has the advantage that in eclipse (by help of plugins) syntax errors are detected, etc.. If you know Eclipse and think it’s too “heavy weight” then you need to be patient for a little bit. In the following days I’ll post a further article in which I’ll describe how you can set up Notepad++ to use it as Perl development environment.
Preparation
Firstly you will need a Perl distribution – I’ve decided on […]

Display PHP errors in Webmatrix

WebMatrix 2 - logo For several weeks Microsofts development environment, called WebMatrix, is available in version 3. As already the first and second version was, WebMatrix 3 is a free development environment for websites and web applications of different platforms such as ASP.NET, PHP, and HTML5.
I use WebMatrix from time to time to test, among other things, just one or the other PHP script. Sadly the provided/integrated web server shows by the default settings, so as it is delivered, no PHP error messages. So when the gremlins sneak in your PHP script and you have not caught all code in try-catch blocks, you only see a white page in browser. For productive environments this seems to make sense, but for a development tool, this is plain and simple said – bullshit!
To show the, in my opinion very helpful, […]
