Intro This article describes how to configure your Linux system to display an nice graphical image from the BIOS until your application or the login manager appear. No text should appear on the screen during that time. The web is full with descriptions and tools that cover tiny parts of this process, however there seems to be no document that covers the whole path end to end. This document wants to do this and cover the whole stretch. Read on

Damit die Hilfe im Taxme 2006 erscheint, musste ich: das Paket libxul0d installieren (welches /usr/lib/xulrunner/libgtkembedmoz.so enthält, welches Taxme benötigt) das folgende Startscript schreiben: #!/bin/sh # offenbar braucht SWT libgtkembedmoz, welches # TaxMe2006: z.B. in libxul0d in /usr/lib/xulrunner/ liegt # siehe http://www.

I needed a ring buffer in Ruby, and since a web search didn’t yield anything I did it myself. Here you go, use as you wish: Simple RingBuffer implementation ================================ see class RingBufferTest below for usage examples ================================================= class RingBuffer \< Array alias\_method :array\_push, :push alias\_method :array\_element, :[] def initialize( size ) @ring\_size = size super( size ) end def push( element ) if length == @ring\_size shift \# loose element end array\_push element end \# Access elements in the RingBuffer \# \# offset will be typically negative!
