Congratulations to Twitter! Twitter is Also Starting Voice Chat But It Does Not Seem To be Secure One.

Good news for twitter fellows. They are planning to start voice chat facility for their users.

Twitter is arranging this facility through a third party voip service provider. In the beginning, users will be able to call for two minutes only but twitter may increase this time period once they successfully test the beta version.

The third party which twitter has engaged (jajah) for this project, has only a one-layer security system. If this is true, then twitter calls will be quite insecure both from viruses and hackers point.

There are a lot of speculations about the new feature of twitter but we can’t say anything final right now. It is presumed that user will be able to make their numbers personal while chatting. They will be able to ignore calls, block calls and so on.

There are a number of other companies that have started voice services like google and before the introduction of this feature, people were expecting that this might affect the voip service but it never happened. Google and other companies could not provide the quality that users were used to. In spite of this fact, there is a race between google, twitter and facebook and other companies for voice communication facility. It is a fact that many users will never use these newly introduced services because of privacy, consistency and other security issues.

An introduction to Satellites And Their Types

Scientists define satellite as any object that revolves around another object. Moon is an example, which is orbiting around the earth, however, for ordinary man satellite refers to a man made space station that is moving around the earth in the space.

Man made satellites are sent in to the space for five different purposes.

1:- Monitoring the weather of our heavenly planet.
2:- Guide the airplanes, ships etc.
3:- Mapping and observing earth surface.
4:- Broad casting television transmission.

First weather satellite was sent in to space in 1960 (Tiros 1). Since then many satellites have been sent to the space and the information sent by them is shared by the whole world through radio, TV and internet. Weather forecast has become a part and parcel of TV and radio news.

Navigation satellites help aeroplanes, submarines and ships in navigation. They can easily determine their position on earth with the help of a navigation satellite in space. The most popular of all is GPS or global positioning system. It was developed by US military but now it is being used by many other countries and institutes also.

Satellite televisions have become a household. We need a receiver (dish on the roof) to receive this type of transmission.

Old phone sets are not too useless to throw away

Now a days echo friendly consumer goods are selling in the market like hot cakes. Most of the manufacturers are trying to adopt echo friendly or environment friendly technologies for their goods. This “echo friendly” mania has given a boom to the recycle industry. We all know that plastic bottles and other plastic items are recycled successfully.

Now there are people who are trying to recycle the old phone sets also. The large and old cell phones that seemed to be useless with the advent of new technologies like internet phone service etc., are being recycled successfully. Now you don’t need to throw away your old phone sets because it may give you some bucks even in this condition.
