Byebye Logitech diNovo, hello Microsoft Arc?

Well, I’ve complained quite a lot about Logitech already, so after my problems with the diNovo edge started, I finally switched to a Microsoft keyboard, at least for the period until the repaired diNovo edge returns. I wanted to switch the brand for quite some time now, but there was simply no alternative if you are used to low profile keys from your notebook or diNovo keyboard. Luckily this finally changed as Microsoft has presented an ultra-flat keyboard called the “Arc Keyboard”, which features quite a nice design while being really small (and 60% cheaper than the diNovo edge). Well, the Arc keyboard looks really great. You can’t complain anything about its looks, but does it work as well as the diNovo edge?

The Perfect Home Server

Perfect? Is that even possible? I guess not, but my newest server is pretty close in my opinion.

Notebook and other small devices’ power supply efficiency

Green IT is a big topic, that’s why more and more computer power supplies get a 80 PLUS label for showing off their superior efficiency. But if you every decide to run a Intel Atom based PC, use a PicoPSU, just power your notebook or charge your phone, you won’t really find out how efficient the power supply is. I came across this problem while searching for an efficient power supply for my new Atom-based home server. First, I wanted to use an 80 PLUS 350W power supply, but after reading some reviews, I found out that they are totally inefficient (<50%) on low load (<50W), which the targeted power consumption of my new home server is supposed to be. So I googled and found the PicoPSU, advertising >93% efficiency. Wow great, but wait, it needs to be powered by 12V DC. How efficient is the converter from 110/220V AC to 12V DC? No word on the manufacture site. I tried to google for efficient converter, but had no luck, so I gave up… until the case of my new home server arrived, a Gigabyte MIB T5140. Read more »
