Below there is again a very special article. I think the people who are affected will understand what it is about. All others must be said that the next article will be for a wider audience again.
Some time ago I wrote an article about small progress bar script of mine, which is implemented entirely in JavaScript. Particular attention I had laid in part to the nice rounded corners. (See the following screenshot)
Javascript only Progressbar
Originally, I had realized the transparent corners using own paths, which I created and filled as shown below.

ctx.globalCompositeOperation = "copy";
ctx.fillStyle = "rgba(0,0,0,0.0)";
ctx.fill();

Unfortunately I had to recognize that the script was not working correct any longer. But the JavaScript console of different browsers (IE, FF, Chrome) curiously gave me no errors or warnings.
After some googling I found out that the globalCompositeOperation “copy” is not […]

wpSuggest – find the right keywords for your WordPress articles

Posted by Raffael on 04/28/2013 Posted in Web Tips, Wordpress Tagged SEO, seo4wp, Uwe Ramminger, Wordpress, wordpress keyword finder, wordpress seo plugin, wordpress title seo, wpSuggest

Today I want to present you a WordPress plugin once again. But let us start with a short introduction.
Google’s autocomplete feature called Google Suggest should be known by everyone who uses Google. (And that should probably be the most.) It is really convenient if you do not have to type in the complete search phrase everytime, because Google already suggests, what you actually wanted to write/search.
However, Google Suggest offers even more. Because if you do not know which keywords you need to use exactly, or want to know what is popular, so you just type a few letters or a word and then Google is proposing all suitable or relevant search phrases. And here we come to the WordPress plugin, that I want to introduce you today.
Uwe Ramminger from seo4wp.de namely has developed a small […]

How to stream your pictures and videos to any browser from your Android device

Posted by Raffael on 04/28/201304/28/2013 Posted in News & Apps Tagged Android, show android photos wireless on pc, sony mobile communications, stream from android to browser, stream video and picture from android to tv, vscreens

Now that’s success! I have just tested the vscreens app for Android and am really excited. But first things first.
vscreens is a free app from Sony Mobile Communications. But kindly runs on any device with Android (version 2.1 or newer needed) and not only on the Sony devices. With vscreens images and videos can be quickly streamed from your smartphone, simply and wireless, to any device that has a browser and an internet connection.
For this purpose, you have just to surf to www.vscreens.com, open the vscreens app on your Android device and scan the QR code on the target device. Then you select those pictures and videos from your smartphone you want to stream and they’ll appear directly on the target device. If the target device and smartphone are in the same Wifi network that’s going to be really fast. (But it will also work with your mobile internet connection.)

How to retrieve default browsers path in C#

csharp_standard_browser Below it will be about how to find the path to the default browser on Windows systems with help of C#. This makes sense, if you want to open a file using Process.Start () in the default browser.
Although one might assume that every Windows user has installed Internet Explorer and you should therefore simply use this to view files, but it does not necessarily increase the confidence of the user into the own application. So at least I, as a user, would be annoyed of my program, if this would always launch Internet Explorer instead of Firefox, which I have set as the default browser.
Now there are two ways to open the default browser in C #. Both have their advantages and disadvantages.
Option 1 – Process.Start() with an URL
The easiest way to launch […]

Are you one of those people who used to (or still do) spend hours, sitting in front of a game console? I for one was never the hardcore gamer and have only owned one console, but I loved my N64.
When I moved, I found some of my old N64 games and felt the need to once again play Super Mario World. Unfortunately it stayed with the discovery of the games. My N64 itself is gone without a trace.
Then last week I stumbled “accidentally” on a N64 emulator for Android. It’s called n64oid and is apparently a bit longer on the market. But to me it passed so far.
Anyway, I got spend the $4.99 and have thrown me n64oid on my Samsung Galaxy S2. And what can I say? I’m excited!
Although it runs not all […]
