Since the coming of the Raspberry Pi Model B, single-board computers (SBCs) have become a prevalent force in the development world. The biggest-little revolution: 10 single-board computers for under $100 article tells that these pocket-sized devices have taken the online maker community in particular by storm, providing PC functionality to a plethora of open-source projects →

The fields of electronics, computers and telecommunications is filled with acronyms. To help in surviving on this world of acronyms I started to compile in the 1990′s my own list of acronyms, and you can find my collection of acronym definitions (over 19000 definitions) at ePanorama.net acronym search.

USB was originally designed for desktop use, but it is increasingly used for industrial applications. For USB to survive in those environments, it needs to be made more rugged. It means that ruggedizing USB for ground loops and using better (more protection and better locking) connectors are often needed. Ruggedize USB connections for tough environments →

Do LEDs cause blindness? article tells that According to a study led by Dr. Celia Sánchez-Ramos, of Complutense University in Madrid, prolonged and continuous exposure to LED light might be sufficient to damage the retina. Her study, published in the journal Photochemistry and Photobiology in 2012 found that LED radiation caused significant damage to human →

Software freedom is an interesting concept, but being able to study the source code is useless unless you are certain that the binary you are running corresponds to the alleged source code. It should be possible to recreate the exact binary from the source code, but a simple analysis shows that this is very hard →

The History of CTRL + ALT + DELETE article tells that in spring 1981 David Bradley created a keyboard shortcut that triggered a system reset without the memory tests. In the fall of 1981, the IBM PC hit shelves. It wasn’t until the early 1990s, when Microsoft’s Windows took off, that the shortcut came to →

When I was researching for my BeagleBone Black I saw in material two things I had read about earlier: Cloud9 IDE on node.js. I wanted to test node.js. Node.js is a platform built on Chrome’s JavaScript runtime for easily building fast, scalable network applications. Node.js uses an event-driven, non-blocking I/O model. The idea of using →

When I was researching for my BeagleBone Black I saw in material two things I had read about earlier: Cloud9 IDE and node.js. Cloud9 IDE is an online development environment for Javascript and Node.js applications as well as HTML, CSS, PHP, Java, Ruby and 23 other languages. It promises that you can write, run, and →

Software defined seems to be the hype buzzword nowadays for many technology areas: We have Software-defined radio, Software-defined networking, Software defined storage and software-defined data center. Some days ago AllThingsD ran a piece endorsing the idea of the software-defined data center titled What Is the Software Defined Data Center and Why Is It Important? Slashdot →
