Based on a statistical analysis of all the Kepler observations, astronomers at UC Berkeley and University of Hawaii, Manoa now estimate that one in five stars like the sun have planets about the size of Earth and a surface temperature conducive to life. “When you look up at the thousands of stars in the night sky, the nearest sun-like star with an Earth-size planet in its habitable zone is probably only 12 light years away and can be seen with the naked eye.…

When you ssh into a machine, you get prompted for a confirmation of the key fingerprint. This happens only the first time a machine is sshed into. After that, there will be an entry added in the ~/.ssh/known_hosts file which will be used. There are two simple ways (both leaves you open to man in the middle attacks) this prompt can be bypassed. Pass extra parameters to ssh command By setting the StrictHostKeyChecking to no via -o, we can bypass the prompt by not checking ~/.…

Those who undertake to study the language for any other reason than the sheer joy of it will always be frustrated. Whatever the reason they started, every single person who has undertaken to study Chinese sooner or later asks themselves “Why in the world am I doing this?” Those who can still remember their original goals will wisely abandon the attempt then and there, since nothing could be worth all that tedious struggle.…

Stars and Planets are two different but very similar objects. Some of the properties that differentiate them are: Stars undergo nuclear reactions that burn hydrogen in their cores. For an object to have high enough temperature in its core to burn hydrogen, it needs to have a mass of at least 75 times of Jupiter. Anything smaller than that would be considered a planet. Stars form when a cloud of gas collapses under the influence of gravity.…
