remove old ubuntu kernel

after few times you do aptitude full-upgrade, you will end up with many kernel images. many people new to linux dont even know it's there. but it's there. and it can be many of them. wasting quite some spaces, especially if you're on old small 4gig harddrive, it matters a lot.

well... there're many ways you can remove old kernel on ubuntu. and here's my way..

first... find out which kernel installed:
aptitude search linux- | grep ^i

that will also show installed old linux-header (source). you might want to remove them too.
now let's remove them:
sudo aptitude purge linux linux-headers-2.6.24-16-server linux-image-2.6.24-16-server linux-ubuntu-modules-2.6.24-16
sudo aptitude purge linux linux-headers-2.6.24-17-server linux-image-2.6.24-17-server linux-ubuntu-modules-2.6.24-17
that's all it.
that should reclaim at least few hundreds megs space.

guess what... it also works on debian and all distros based on these two.

update. shorter, easier...

sudo apt-get purge '.*-2.6.24-16-*' 
sudo apt-get purge '.*-2.6.24-17-*'

Blogger Buzz: Show off your favorite blogs with a Blog List

blogspot now have a new gadget that allow us to put our blog list to our sidebar. you might already have blogrolls using some other services. maybe the google reader's or others.
but all that mostly using javascript! you get what i mean? js means only browsers can see it and search engine bots cant see your blogroll.

and you can guess it already. this new blog roll is 100% SEO and it can even raise your other blogs pagerank.

let's see it in action...

ultimate htaccess blacklist

just found another great resources on htaccess blacklist by perishable press. it's called ultimate htaccess blacklist. similar to my previous close to perfect htaccess ban list from webmasterworld forum. but the htaccess have all the rewritecond in one single super long line.

also, it have very nice and almost complete htaccess stuffs.

then, it's also building so-called 3G - third generation - blacklist which include a bunch of redirectmatch stuffs. but be carefull with these. they could/might breaks your cms if you do not understand the logics there.

among all, i will certainly put this into my htaccess:
# PART III: USER AGENTS
SetEnvIfNoCase User-Agent "Jakarta Commons" keep_out
SetEnvIfNoCase User-Agent "Y!OASIS/TEST"    keep_out
SetEnvIfNoCase User-Agent "libwww-perl"     keep_out
SetEnvIfNoCase User-Agent "MOT-MPx220"      keep_out
SetEnvIfNoCase User-Agent "MJ12bot"         keep_out
SetEnvIfNoCase User-Agent "Nutch"           keep_out
SetEnvIfNoCase User-Agent "cr4nk"           keep_out

order allow,deny
allow from all
deny from env=keep_out

just go check it out for all those .htaccess stuffs and come back tell me what do you think and how you build your htaccess
