Ripped a DVD, Surfed the web without worry of spyware, setup LAMP server, Installed Music Player Daemon and controlled it from my windows box, Installed Gnump3d and streamed music to my Windows box, Setup FTP and gave access to my friends for a laugh (ended up with a few albums and porn being uploaded @_@), got 4 of my friends to telnet into my box and we were all echoing each other on the terminals. Installed and played Unreal Tournement and WolfET natively using OpenGL I also setup a Jabber and IRC server and had some fun with friends giving +o +v to each other :P
I have had a lot of fun working with linux on small devices such as some of the home routers. There is a ton of great packages that you can add to these devices once you have them running linux, I especially like the packet protector project because it puts a lot of my favorites (such as snort inline & vpn) all together in one place, plus it gives a nice user interface to manage it all.
1. The first time i compiled my own (working) kernel
2. One of my first mplayer installations compiled from source. Man oh man, two weeks it took me. But did I feel good afterwards. :-)
3. Seeing how easy my boyfriend crossed to linux. I tried to keep him back because I thought it wasn't gonna be his thing but he still uses it instead of windows. (three months now) I got a rush from seeing how my non-technical non-geek honey handled it, man i was SO proud. But also from seeing that linux has reached that stage where non geeks can work with it as well. So i was proud of linux too. :-)
My office needed backups of all invoices printed, but didn't want to waste paper by printing two copies, so I set up a print server that makes pdf backups of everything that is printed before it's sent to the printer.
everything I do with linux is cool
My wife does a lot of cool stufff - she plays WormsArmageddon, StarSraft and flobopuyo
we've got GigaBit LAN at home
All I do is - control my Linux-box with remote control (lirc) - it makes my friens crazzzy!!!
How about installing new hardware without using the cds that came with them. I have a digital camera which I used to use in windows and had to install a lot of garbage, bloated software to get it to work. Also it would take about 3 restarts to get all of this stuff installed. Under Linux I plug the camera in and select the model from a list, and it just works. Fantastic.
Also I guess i like never having to restart after installling things, i had forgotten how annoying that was.
1. discovering linux in 1996
2. converting our coporate confuto network surveilance to nagios with sms notifications and apache auth against windows active directory (currently working on convincing my boss to activate netflow and nbar on the routers so we can graph it with cacti)
dcfldd if=/dev/sda | hexdump -C | grep 'I don/'t love him anymore.'
will search the entire drive for the string "I don't love him anymore.", bypassing any security, and with any type of partition. It searches all deleted files, too. Every single spec of disk space is searched, for any string you supply. And, it prints to the terminal so you don't write a file over what you hope to find. The disk is not altered in any way.
You can search the memory on a running machine, too:
dd if /dev/mem | hexdump -C | grep '<string>'
You would be amazed what builds up in memory when you let a machine run for weeks. Memory doesn't get written over until it is needed for something else. When you close a program, whatever it wrote to memory is mostly still there. The memory is marked "free" for other programs to use, but I've found document text from documents I hadn't opened for days. You can use that to recover files you didn't save, too.
dd if=/dev/mem | hexdump -C | grep A 1000 B 1000 'someuniquestring' > recoveryfile.txt
that returns 1000 lines before, and 1000 lines after the string. In hexdump a line is 16 bytes.
