My Perfect Raspbmc Setup

Since I’ve received my Raspberry Pi couple of months ago, it took a while for me to find out the perfect configuration. By perfect configuration I mean running 1080p-HD-videos without clipping, caching, freezing or anything else. Just lay back and relax the movie.

Daily Hacks: Youtube & Google Chrome

If you want to link a youtube video and want to play it from a certain time, just add ‘#t=xxmyys’ to the end of the link.

However up till now I did not figured out how to embed the clips by this way. It seems not to work in the embedded code.  :-( Suggestions?

Want to send a link to a web site from Google Chrome without installing any extension? Here you go: Select “Add bookmark” from Bookmark Manager and write into the URL-field
The drawback of this method is that an email program (Outlook, Thunderbird, etc) should be installed on your system. By clicking on the bookmark, a new mail draft will be opened to send an email with the subject containing document title and in the body the link to the site. Modify, if you want.

Set DIR command default parameters

Since I don’t like the the default parameters of the DIR command in the command line mode, I wandered if there is a way to set it permanently, to avoid typing each time “DIR /O:G/P” for example. And of course there is a way, following step-by-step for XP, but should be kind of similar for other windows versions too:

  1. Win + Print opens System Properties dialog
  2. Klick on the Advanced tab
  3. Environment variables
  4. Add a new variable with the name DIRCMD and the value(s) you want to be displayed in System variables field.
That’s it. Enjoy.


What is Exception-Safety?

Informally, exception-safety in a component means that it exhibits reasonable behavior when an exception is thrown during its execution. For most people, the term “reasonable” includes all the usual expectations for error-handling: that resources should not be leaked, and that the program should remain in a well-defined state so that execution can continue. For most components, it also includes the expectation that when an error is encountered, it is reported to the caller.

More formally, we can describe a component as minimally exception-safe if, when exceptions are thrown from within that component, its invariants are intact. At least three different levels of exception-safety can be usefully distinguished. These distinctions can help us to describe and reason about the behavior of large systems.

In a generic component, we usually have an additional expectation of exception-neutrality, which means that exceptions thrown by a component’s type parameters should be propagated, unchanged, to the component’s caller.

Eclipse Helios + MinGw: Adding icons to the application build

Recently I’ve worked a Win32 API tutorial ( for creating a simple graphical program. At the point where the icon has been added to the app, however, I’ve got stuck. The compiler did not give an error messages but neither the icon nor the menu did appear. What the hell?

CSS3 Scribble: Rounded Corners

In CSS3 finally no more hacks are needed in order to get round corners. A simple command is all you need:

border-radius: 15 px;

Unfortunately FF does not support (yet) rounded corners from the scratch. An extra prefix is required. Following makes it work:

-moz-border-radius: 15 px;
