Through our stages of technological evolution, we have come to a point where in certain aspects, we an say that we have reached a position where being environmentally friendly does not come at a cost. Continue reading “Save the planet, switch to CFL”
Wading through the marshlands of object oriented programming, one must at one time realize that there are two fundamental skills that one needs, in order to truly embody the spirit of object oriented paradigm.
- The ability to abstract ones thought processes.
- Perceive the harmony within abstract chaos.
I was searching for ways to implement FusionCharts within blogs and finally decided that WordPress would be the ideal place to do so.
If you are not already into WordPress, it is a highly popular open-source online content publishing application based on PHP. You should have a look at http://www.wordpress.org for detailed information. Its theme-based highly configurable and flexibly environment makes it an ideal blogging and content-management platform for most users. Continue reading “FusionCharts In Your WordPress Blog”
It all started when I decided to do a clean install of Windows Vista onto my HP TX 1000 Tablet PC. In order to remove the set of unnecessary applications that come pre-installed in their PCs, many users prefer doing a fresh install of the OS from a standard installation media (not from the recovery disc.)
The issue: Facing error while calibrating the Tablet PC screen in a fresh install of Microsoft Windows Vista. Continue reading “Calibrate Tablet PC Screen”
However, when I kept my Dataone connected for long hours using my Router, I faced major issues. The DNS failed to respond. The issue was not (only) latency, but also “uptime” and reliability. At certain times, some of the automatically assigned DNS tends to have high latency and also after long period of connection, the DNS tends to fail totally.
As of today (September 9, 2002) there are three main cellular technologies: Older analog FDMA (Frequency Division Multiple Access), modern GSM TDMA (Time Division Multiple Access) and Newer CDMA (Code Division Multiple Access.) People mostly know of the latter two and the first one is almost wiped off from the history of Cellular Network technology.
I am not going too deep into the technical aspect of all the networks and am just giving an outline of FDMA.
Analog transmission is considered an “older” cellular phone technology. Back in the early 198o’s, it was the first network technology to be deployed successfully. FDMA is used exclusively for analog cellular systems, even though in theory FDMA can also be used with digital networks.
Essentially, FDMA splits the allocated spectrum into many ‘channels,’ each of approx 30 kHz bandwidth. During a data transfer, in form of audio or video, an FDMA networks allocates the entire channel to the phone and the data is modulated into this channel’s frequency band and sent over airwaves. At the receiver’s end, the information is recovered using a simple band-pass filter. The phone then uses common control-channel function to acquire channels during Handoffs ((Handoff is the term used for the broadcast site switching phenomena.)).
