Open SAP GUI from HTML out of your webbrowser

SAP aus Browser aufrufenSome time ago I got into a discussion about whether it is possible to open transactions in the SAP GUI out of the browser. The opinion of the colleagues was unanimous – start SAP GUI from browser is something not be done.
However I have maintained and created a small proof-of-concept. Because it works. Ok, it’s not pretty, but it works. And that’s how to call the SAP GUI from the browser.
sapshcut.exe and what you can do with it
The solution works (among other things) using the sapshcut.exe (short for SAP Shortcut). This .exe file allows to start the SAP GUI parameterized. The possible parameters ranging from user via logon language up to the executed transaction. A complete list of possible parameters can be obtained by calling the sapshcut.exe with the parameter -?. (See screenshots below.)

RadioduinoWRT – a do it yourself webradio

RadioduinoWRTToday 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

Close Pixelate TutorialToday 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.

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.


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 to the […]

How to add multiple free images to your eBay auction

ebay_logoToday 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:
