The Embedded Angle

First of all I must mention that this post is practically not Raspberry Pi related. Nevertheless the book reviewed here has instructions on installing OpenELEC on the Raspy and that is all. Some time ago I made a review on another of PACKT Publishing's books . It was about RaspBMC, and I complained in it about why there was no additional information for competitive systems like OpenELEC for example. So here it is - a separate book dedicated solely to it - Instant OpenELEC Starter by Mikkel Viager . The quickest OpenELEC intro The book comes as part of a series entitled INSTANT (Short | Fast | Focused) . This mantra sets the writing in a pretty tight frame of size (maximum number of pages) and allowed topics. That leaves almost no ground for criticizing the book's contents. Despite that I'll make a few points that came to my mind. All those small books that are a hundred and something pages or less (in this case they are just fifty), always tend to make me fee

Part II - In search of solution     The task The questions posed in the situation explained in part I  are related mostly to how can be achieved an optimal performance. In order to measure the strength of the WiFi signal and its throughput I already had a tool good enough for the job - my Raspberry Pi equipped with its Wi-Pi module. But I also needed something else - a benchmark - a device with inherently good performance in terms of WiFi reception. Luckily my laptop has proven to be pretty good in this and I have this axiom in my mind, that it has a very capable antenna. This is kind of biased opinion but for my small experiment I guessed such bias could've been neglected. On the other hand I already had a second Raspberry Pi unit, which could make a proper second WiFi-meter.  The two measuring device prior to powering up At that point it was clear to me that with three WiFi-meters I was going to test four devices. This means that the task has two dimensions: Test and
