Quick note how to list files without directories.

Windows:
dir /a:-d

Linux:
ls -l | grep ^-

Second command should work also in Mac OS X from terminal, but will have to check it just to be sure.

I’m using VMWare Workstation a lot to virtualize my testing environments. Along with many other OSs that I’m using there are Linux systems and one of the most useful functionality in Linux are (in my opinion) virtual terminals. Virtual terminal is like your another monitor, so when doing many things you can avoid mess by using few “desktops” instead of one. In Linux you’re creating and switching between terminals by pressing CTRL+ALT+F1-12. Problem with VMWare is that CTRL+ALT has special meaning there, so pressing mentioned combination does nothing. Instead you can use workaround, first press CTRL+ALT+SPACE, then release SPACE and press F1-12 button.

Today I’ve faced embarrassing situation, I’ve forgot my root password to my Debian VM. I know this is lame. But happened, so I’ve started looking for solution and after viewing few more or less helpful websites I’ve compiled my own solution. To reset root password on Debian (Lenny) do following:
1. During start of PC when there is your boot manager displayed press “e”.
2. Move arrow on the keyboard to highlight “kernel”.
3. Press “e” again.
4. On the displayed line change “ro” to “rw” and add “init=/bin/bash” at the end. Without quotation marks of course.
5. Press Enter and then “b” to boot your Debian.
6. Debian would boot to bash console with root privileges. Now execute “passwd” command and input your new password.
7. Reboot your system.

That’s it. Your root account is now back. Enjoy!

I’m using Debian Linux as a second operating system. Previously I was using it only for my servers, but now I’ve decided to start doing some software development on it. As I love bash environment, the choice of text editor was pretty obvious, Vim, the greatest editor ever made. But problem was that I like my syntax to be colored, it’s easier to write program code then. No problem, I thought, quick searching via Google gave me the “:syntax on” command which should enable what I’ve wanted. After typing it in my Vim I’ve received a message “command not available in this version”, WTF? So I’ve searched and searched, and searched a little more:) And finally solved it!

To have colored syntax in Vim on Debian:
1. Login as root.
2. Execute “apt-get install vim-full”.
3. Edit “/etc/vim/vimrc” and uncomment line with “syntax on, by simply deleting ” sign.

That’s it! It’s working now. Last step (3) is not necessary, but it gives colored syntax to all users without need of typing “:syntax on” command every time Vim is started. Hope it would help somebody, because it took me a while to find this solution, so maybe I would spare this to you. I know it’s not best solution, because it’s installing a lot of stuff which you (and I) will probably never use, but for now it’s the only one I have. If you know how to get same result with less things to be installed, please let me know.

Last night I’ve moved from Linux to Windows hosting. And this showed the new WordPress issue (or my lack of skills). I’ve moved everything and migrated SQL DB, but it didn’t worked. I was receiving error 500. As Google is giving me only tips how to migrate from Windows to Linux, not backward, I was forced to figure out something. As you can see I’ve succeeded. Blog is up and running, however Flickr plugin isn’t working properly, but I hope to fix it in few coming days. Enjoy!
