Nach kurzer Suche fand ich den Grund in den AirPort-Settings. Wobei dies nicht unbedingt die Ursache ist, aber zumindest das “gewünschte” Verhalten zurückbrachte.

In den AirPort-Einstellungen (Systemeinstellungen > Netzwerk > AirPort > Weitere Optionen) lässt sich eine Option aktivieren, welche für das De- & Aktivieren von AirPort nach dem Administrator-Passwort fragt.

Sobald ich diese Einstellung deaktiviert hatte, konnte ich AirPort wie üblich via Menüleiste abschalten.

Recently I had some troubles with my Doom 3 game being f*cked up a little. One of the issues was, that the resolution has been reset to 640×480 pixel and I could only change it back to 1024×768 pixel the max.

However, I was able to fix it and playing in pretty widescreen again. Here is what you need to do for your custom screen settings:

The following 4 parameters from within your DoomConfig.cfg-file are important:

• r_customHeight
• r_customWidth
• r_aspectRatio
• r_mode

Here is an example from my own config, set to 16:9 widescreen with 1280×800 pixel:

seta r_customHeight "800"
seta r_customWidth "1280"
seta r_mode "-1"
seta r_aspectRatio "1"

The value “r_aspectRatio” can be set to…

• “0″ for 4:3
• “1″ for 16:9
• “2″ for 16:10

“r_mode” set to -1 tells the game to use the values for r_customHeight and r_customWidth.

First I thought this was something that had been put in the Terminal’s startup message (called motd – Message of the Day, which can be edited with “$ pico /etc/motd”). However, this was not the case.

Fortunately a short web-search delivered the answer and solution to this strange occurrence: the message is a part of the built-in Unix mail processing system, called “mail” or “mailx”.

This application provides a functionality called “sendmail” which is commonly used in website development to generate an e-mail, for example in a contact form. And this was also the reason why I had that suspicious mail notice in my Terminal.

How to get rid of those messages

By using the follwing Terminal command, you will receive an overview of the mail messages – namely the mail inbox:

$ mailx #launches the unix mail app
Mail version 8.1 6/6/93.  Type ? for help.
"/var/mail/user": 1 message 1 unread
>U  1 MAILER-DAEMON@...  Mon Feb  8 21:41  81/2505  "Undelivered Mail Returned to Sender"
?

The prefix “U” stands for “Unread”. There are other prefixes such as “N” = New and “> ” = Read.
From here you can use now several commands to handle the messages (display the list using “?”):

? ? [RETURN]

Command

Description

t 

type messages

n

goto and type next message

e 

edit messages

f 

give head lines of messages

d 

delete messages

s 

file append messages to file

u 

undelete messages

R 

reply to message senders

r 

reply to message senders and all recipients

pre 

make messages go back to /var/mail

m 

mail to specific users

q

quit, saving unresolved messages in mbox

x

quit, do not remove system mailbox

h

print out active message headers

Most commonly you might want to read the message(s) and/or delete them. To do so, type:

? message-id [RETURN]
#Use ctrl+v to skip through the message

Afterwards simply use the following command to delete a message:

? d message-id [RETURN]

There are for sure some visually nice alarm clocks to use on OS X, such like the 3-2-1 Dashboard timer-widget.

But for real Geeks, there’s a way over the Terminal for activating an audio-visual reminder, using the following simple command:

$ leave hhmm
$ #f.eg.: "leave 0930" meaning 21h30
Alarm set for Mo 8 Feb 2010 21:30:00 CET. (pid 789)

This activates a leave-timer which will alarm you 5 and 1 minute prior to the given time, such as at the exact time. The date is always your current day.

To disable the alarm, you need to quit the according process using the following kill-command:

$ kill -s kill pid
$ #pid = 789 as in above example

As usual, you can read all details about the “leave”-command by typing “man leave” in the Terminal.

In Microsoft Excel ermöglicht die Funktion

=ZÄHLENWENN(Bereich;Suchkriterium)

das Zählen aller Vorkomnisse eines bestimmten Suchbegriffes innerhalb eines Zellenbereichs.

Was ist nun aber, wenn man die Werte im Zellenbereich nicht komplett mit dem Suchbegriff übereinstimmen?
Beispielsweise wenn ich in folgender Liste zählen will, wie oft der Suchbegriff “zug” vorkommt?

A1: Zugfahrer
B1: Kontrolleur
C1: Service
D1: Zugtechniker
E1: Aufzug

Mit =ZÄHLENWENN(A1:E1;”zug”) erhalte ich das Resultat “0″ (was ja eigentlich auch korrekt/logisch ist).

Man sollte hierfür wissen, dass Excel grundsätzlich das Zeichen * (Stern) als “Wildcard”-Zeichen (Spezialzeichen welches stellvertretend für 0, 1 oder mehrere Zeichen steht) interpretiert. Und dieses kann ich deshalb auch in meiner ZÄHLENWENN-Formel verwenden, um das gewünschte Resultat zu erhalten. Die Formel sieht dann wie folgt aus:

=ZÄHLENWENN(A1:E1;"*zug*")

Hierfür erhalte ich nun korrekterweise das Resultat von “3″!

After searching my way through different Discussion Boards and the official AppleScript Language Guide, I came up with the following working piece of code:

tell application "Finder"
        activate
        set source_folder to choose folder with prompt "Please choose the Source-Folder:" default location ((path to home folder) as alias)
        set source_files to every file in source_folder
        set target_folder to choose folder with prompt "Please choose the Taget-Folder:" default location (":Applications:" as alias)
        repeat with i from 1 to number of items in source_files
                set source_file to (item i of source_files)
                move source_file to (target_folder) -- use "copy source_file to folder (target_folder as alias)" to copy the files
        end repeat
        set question to display dialog "Files have been moved. Move Source-Folder the trash?" buttons {"No, Thanks", "Yes, Please"} default button 2
        set answer to button returned of question
        if answer is equal to "Ja" then
                tell application "Finder" to delete source_folder
        end if
        display dialog "Files moved successfully." buttons {"OK"} default button 1
end tell

* If you want to do a copy, instead of moving the files, change the line

move source_file to (target_folder)

to

copy source_file to folder (target_folder as alias)

Urban Terror is a stand-alone modification based on the Quake 3 engine.

I use to play this from time to time with some friends, usually over the LAN when we meet somewhere. One of us guys does then start a local UrT4 Server, where the others can connect to and play. However, we often have had some issues that stuff like Voting or the map-cycle did not work or meet our expectations. Therefore I looked a bit into how to configure an UrT4 Server – and I will publish some of the main “Good-to-knows” here (most of it can also be found in the Urban Terror FAQ on their website).

Play only the maps you like (= create a maplist)

1. There is a file named “mapcycle.txt” in your Quake 3 > q3ut4 folder
2. Open and modify it, so that it holds only the maps (1 per line!) that you’d like to play

List all available maps

1. Start the game and open the console (alt+cmd+n on Mac)
2. Type “/map ut” and hit TAB – this will display a list of all maps

Ensure that people can auto-download a map they don’t have

This one’s a little tricky, as it requires that you provide an URL to a website, where the map can be downloaded from. This is against what many think, that it will download it from the one who runs the UrT4 Server.

1. When you started the server and you are in the game, open the console (alt+cmd+n)
2. Type ’sv_dlURL “urbanterror.net”‘ and hit RETURN
   (replace “urbanterror.net” with any other website where the map is available under http://website.com/q3ut4/mapname.bsp)
3. As soon as somebody connects to your server now, he/she will be asked to download the map from that website.

Alternatively you can you do this also by adding the “sv_dlURL”-parameter to your servers configuration file in Quake 3 > q3ut4 > server.cfg. But then you have to make sure that this will be loaded when Urban Terror is being started. To do so, open autoexec.cfg within the q3ut4 folder, and add the following command: exec server.cfg

Enable voting

I got Voting only to work when starting the server over a properly configured server.cfg file (see above). However, basically it is controled by the command “g_allowvote”:

1. Check this website, to receive the bitmap (parameter value) specifying what people can vote for: http://www.urbanterror.net/allowvote_calc.html
2. Start the game server and open the console (alt+cmd+n)
3. Type /g_allowvote “536871517″ and hit RETURN
   (between the brackets you must add of course the prior calculated  value)
