pid of processes with open ports

Somehow the netstat of OS X does not have the ability to show the PID of the different open sockets. Instead, use this:

 lsof -i -P 

Thanks to ynniv for that one.

setting default umask

The default umask on Mac OS X systems is 022; I would like it to be 077. In Mac OS X the umask value must be specified in decimal; the octal value 077 is decimal 63. To change the default umask value:

1. Log into an administrator account on your computer
2. Execute the following line into the Terminal window:
   

   /usr/bin/sudo /usr/bin/defaults write /Library/Preferences/.GlobalPreferences NSUmask 63

3. Then execute the following line into the Terminal window:
   

   /usr/bin/sudo /bin/chmod 644 /Library/Preferences/.GlobalPreferences.plist

4. To return the umask value to the default setting of 022, use the following command:
   

   /usr/bin/sudo /usr/bin/defaults write /Library/Preferences/.GlobalPreferences NSUmask 18

my new macbook

Yesterday my dear, old laptop finally called it a day. First thing I did was to buy a new MacBook; The white 2,16Ghz. It’s absolutely amazing. I have a large wishlist of default settings and other stuff I want to change, so I guess the subject of this blog is now: Mac OS X. More or less.

Enjoy!

dell inspiron 8200 media keys and freebsd

To configure the media keys on my Dell Inspiron 8200 to work with Amarok takes three steps:

1. Per default the media keys are not linked to any X keysyms. Put this in ~/.Xmodmap:
   

   keycode 176 = XF86AudioRaiseVolume
   keycode 174 = XF86AudioLowerVolume
   keycode 129 = XF86AudioPlay
   keycode 130 = XF86AudioStop
   keycode 131 = XF86AudioPrev
   keycode 132 = XF86AudioNext

2. Map the keys to the relevant commands – I’m using amarok. Put this in ~/.xbindkeysrc:
   

   “mixer vol +5″
   XF86AudioRaiseVolume
   “mixer vol -5″
   XF86AudioLowerVolume
   “amarok –play-pause”
   XF86AudioPlay
   “amarok –stop”
   XF86AudioStop
   “amarok –previous”
   XF86AudioPrev
   “amarok –next”
   XF86AudioNext

3. Now run xmodmap ~/.Xmodmap && xbindkeys. Put theese commands in your ~/.xinitrc as well.

show week numbers on google calendar

For all the time I have been using Google Calendar I have been somewhat bothered by the fact, that it does not have the ability to show week numbers, which we use a lot in Denmark. The answer is simple – ReCover. Simply add their Google Calendar for weeks starting on mondays.

mouseless (and vim’ish) firefox

Today I will bring vim to your Firefox, enabling you to use h/j/k/l instead of the arrow keys for moving around at webpages.

1. Install the keyconfig extension, which gives you the possibilities of changing the standard Firefox-shortcuts.
2. Install the “functions for keyconfig” extension, which enables you to use keyconfig to configure scrolling.
3. Go to Tools -> Keyconfig and find the options named f4kc_ScrollLeft, f4kc_ScrollLineDown, f4kc_ScrollLineUp and f4kc_ScrollRight, and set the shortcuts to h, j, k and l – respectively

Restart Firefox and you can enjoy the freedom of surfing the vim way.
