Mounting the pendrive � slackware: the hacker’s linux

for the records...-2501

mounting the pendrive � slackware: the hacker’s linux

mount -rw -t auto /dev/sda1 /mnt/pendrive

-rw: readable and writable
-t auto: filetype detected automatically
/dev/sda1: seems that this is the type of device for pendrives
/mnt/pendrive: i had to create the “pendrive” folder in the “/mnt” directory

after having done this, open the “/mnt/pendrive” folder to access its contents. After you are finished with it, close all related “/mnt/pendrive” folders and konsoles, and unmount it with the command:

umount /mnt/pendrive

if it gives an error message saying that it is busy, then give the command:

umount -l /mnt/pendrive

-l: “lazy” unmount which means, it will unmount as soon as the device stops being busy

Mysterious radio waves emitted from nearby galaxy - space - 14 April 2010 - New Scientist

There is something strange in the cosmic neighbourhood. An unknown object in the nearby galaxy M82 has started sending out radio waves, and the emission does not look like anything seen anywhere in the universe before.

"We don't know what it is," says co-discoverer Tom Muxlow of Jodrell Bank Centre for Astrophysics near Macclesfield, UK.

The thing appeared in May last year, while Muxlow and his colleagues were monitoring an unrelated stellar explosion in M82 using the MERLIN network of radio telescopes in the UK. A bright spot of radio emission emerged over only a few days, quite rapidly in astronomical terms. Since then it has done very little except baffle astrophysicists.

It certainly does not fit the pattern of radio emissions from supernovae: they usually get brighter over a few weeks and then fade away over months, with the spectrum of the radiation changing all the while. The new source has hardly changed in brightness over the course of a year, and its spectrum is steady.

Scientists capture 'terrifying' Tolkien-like eclipse (w/ Video)

Scientists capture 'terrifying' Tolkien-like eclipse (w/ Video): "(PhysOrg.com) -- Scientists have captured a 'terrifying' image of a giant Goliath-like star undergoing a two year eclipse. First discovered by a German astronomer 180 years ago, it is the first close-up image of an eclipse beyond the solar system to be captured on camera by scientists."
