Passwords aren’t very secure,we already know this. If you use one that’s easy to remember, it’s easier to guess or brute-force (try many options until one works). If you use one that’s random it’s hard to remember, and thus you’re more inclined to write the password down. Both of these are Very Bad Things. This is why we’re using ssh keys.

But using a key without a passphrase is basically the same as writing down that random password in a file on your computer. Anyone who gains access to your drive has gained access to every system you use that key with. This is also a Very Bad Thing. The solution is obvious: add a passphrase.

But We don’t want to enter a long passphrase every time We use the key!

Thankfully, there’s a nifty little tool called ssh-agent that can save your passphrase securely so you don’t have to re-enter it. Most linux installations will automatically start ssh-agent for you when you log in.

There are Wordpress plugins to highlight code snippets and The WYSIWYG editor is nice, but very often you need to switch to the HTML editor to enter tags such as pre (to type the brush class) and even tt. Also, you don’t have control of how the HTML code looks because the editor keeps reformatting it. The main advantage of using Octopress is that I can use any editor I want.

I own a DELL-vostro-1088 Laptop.i have switched over linux in year 2009,every thing was ok with the installation of drivers except for one.Laptop’s audio jack was not working so no fun with any headfones or external Sound-Box.That time current version of alsa was 1.0.21 or 1.0.22 something like that.i tried upgrading with alsa 1.0.25 still no luck at all with sound output. Googled a lot then i got some where close.i created a alsa.conf file inside /etc/modprobe.d/ directory.then i did this:

1

echo "options snd-hda-intel model=dell-vostro position_fix=0 enable=yes" > /etc/modprobe.d/alsa.conf

it took some time because i was trying with model=dell-vostro-1088 while above line was sufficient.anyway i rebooted the machine and was really surprised to see that my audio jack was working.Now i am enjoying my Creative Sound-Box. Right now Fedora, ubuntu and some other distro has upgraded the version of alsa so no problem with audio drivers. but Redhat-6/Centos-6 are still using alsa-1.0.21 so, i need to do above modifications in order to stay pain free.

Hello Octopress

It feels very nice to switch over Octopress.it is a blogging framework based on jekyll and desined in RUBY.Since there is no need of mysql or any similer type of database system it reduces your effort of management.Store all you data at Github in Flat Files.It’s the Feel of Freedom.But it still needs some tweaking to be done for the better look of Blog.

Thank you Tom Preston-Werner(for jekyll) and B mathis(for octopress).
