ICS (iCal) is a file format for calendars. Most calendaring software uses it. For example, you can import / export it to Google Calendar. If you have a Google Calendar, you can “publish” your calendar to an ICS file, so you can use it with other software like Mozilla Calendar or web services. Microsoft Exchange [...]
Introduction In our student’s dorm, we want to share files. We also have one shared internet connection using ADSL. The download speed is OK, but the uplink is weak. Many students like to use torrents, which quickly drain the uplink and the connection table of the modemrouter. So I set up a server with a [...]
VMware uses virtual disk files as a source to store data from their virtual machines. These files are have an extension of .vmdk and are stored on your local hard drive. There are multiple instances where one would want to access these files without having to boot up the virtual machine. It could be due [...]
(from – http://analogcircuits.posterous.com/reverse-engineering-the-cascode) Cascode (shown in Fig. 1) is well known and widely used circuit for creating large-impedances in integrated circuits. Cascode circuits also provide another advantage i.e. isolation between input and output ports and thereby reducing the Miller-effect and as a result cascodes have a good frequency performance. And when impedances achieved from cascode [...]
I am sure that everyone has given presentations on a beamer / screen and will have to do so in the future. Most people I have seen presenting use the default slide show view in which the laptop/computer shows the same view as the projector / screen. This is quite unhandy when you want to [...]
Why do we perform small signal analysis, when we are analyzing or designing analog circuits? This is a fundamental question that I think, is not discussed rigorously enough in the classes or text books on analog circuit design. I will attempt to qualitatively address this question here in this blogpost. Fig. 1 a) Small-signal MOSFET [...]
Author: Bob Westerbrink Rechargeable batteries aged 6 years or older are, in general, garbage (this also is true for most car batteries). How good are your rechargeable batteries? You can test your batteries by measuring the time it takes until they are empty while they power a LED or something similar with a small resistance. [...]
First a short introduction on Instagram, it is an iphone app for taking pictures, adding filters to make them look retro, and then for sharing them with sites like Twitter, Flickr, Tumblr, and Facebook, more importantly, it’s a simple social network of other people’s photos. You can “like” or comment on the photos, and see [...]
