Domain Names and IP Address

Friday, March 5th, 2010 at 11:44

Domain names are essentially a human way of allowing the Internet to work. Every single computer that exists on the Internet is given a number to identify itself (an “IP address” such as 69.73.172.201). Within this sequence of numbers is also a way of finding out who else is in your “group” and where to find other “groups” but that’s starting to get a bit complex for our needs here. (more)

Virtual Hosting vs Virtual Private Server

Wednesday, March 3rd, 2010 at 13:58

Virtual hosting is a method for hosting multiple domain names on a computer using a single IP address. This allows one machine to share its resources, such as memory and processor cycles, to use its resources more efficiently.

One widely used application is shared web hosting. Shared web hosting prices are lower than a dedicated web server, because this allows many customers to be hosted on a single server. (more)

Website Domain Name Registration

Tuesday, March 2nd, 2010 at 09:44

The domain facilitates the users of the internet to interact with different types of the websites. .com, .net, .org are the website domains name. It is the rule that the name of the server and the ip addresses could be interchangeable. The cheapest domain name just $ 10 on yearly basis, so it means that the middle class person can easily have the cheapest one. There is the procedure of registering the domain and also one can buy at the high rate, now the choices are at the part of the user that whether to go for the cheapest one or for the expensive one.

Hacker Personality Characteristics

Wednesday, February 24th, 2010 at 18:34

The most obvious common ‘personality’ characteristics of hackers are high intelligence, consuming curiosity, and facility with intellectual abstractions. Also, most hackers are ‘neophiles’, stimulated by and appreciative of novelty (especially intellectual novelty). Most are also relatively individualistic and anti-conformist.

Although high general intelligence is common among hackers, it is not the sine qua non one might expect. Another trait is probably even more important: the ability to mentally absorb, retain, and reference large amounts of ‘meaningless’ detail, trusting to later experience to give it context and meaning.

How does encryption work

Wednesday, February 24th, 2010 at 03:30

Encryption works by encoding the text of a message with a key. In traditional encryption systems, the same key was used for both encoding and decoding. In the new public key or asymmetric encryption systems, keys come in pairs: one key is used for encoding and another for decoding. In this system everyone owns a unique pair of keys. One of the keys, called the public key, is widely distributed and used for encoding messages. The other key, called the private key, is a closely held secret used to decrypt incoming message. (more)

Helping Hacker Culture Grow

Tuesday, February 23rd, 2010 at 14:33

You may ask why we need to help hacker culture grow, they do bad thing, destroy a system, and more, and more…

If you think like above, you know nothing about hacker, here’s the text of a letter RMS wrote to the Wall Street Journal (some years ago) to complain about their policy of using “hacker” only in a pejorative sense. We hear that most major newspapers have the same policy. (more)

How Safe is Restriction by IP Address or Domain Name

Monday, February 22nd, 2010 at 09:19

Restriction by IP address is secure against casual nosiness but not against a determined hacker. There are several ways around IP address restrictions. With the proper equipment and software, a hacker can “spoof” his IP address, making it seem as if he’s connecting from a location different from his real one. Nor is there any guarantee that the person contacting your server from an authorized host is in fact the person you think he is. The remote host may have been broken into and is being used as a front. (more)
