.vimrc options to assist with perl coding
Sunday, January 16th, 2005VIM option file
Sunday, January 16th, 2005Setting VIM options:
http://babbage.cs.qc.edu/courses/cs701/Handouts/using_vim.html
The installation program normally puts a file named .vimrc in your home directory. On Windows, the file will be named _vimrc, and will be in the directory where Vim was installed. For example, when I installed version 6.1, it was placed in D:\Utils\Vim\vim61, and the _vimrc file was put in D:\Utils\Vim. Also, the Windows environment variable, VIM, was set to D:\Utils\Vim.
The standard .vimrc file supplied with the Vim distribution is not quite correct for use in this course. You need to set the tab width to something small, you must set the option to replace tabs with spaces, and you need to tell vim to wrap lines longer than 72 characters.
I also have some keyboard shortcuts that I like to use, mostly so I can enter certain commands while I am in insert mode. Here are links to two .vimrc files, one for Windows and one for Unix that you may use as a model for your own. Feel free to modify them as you wish, but be sure not to change the expandtab and tw options!

Turn that irritating beep off: set visualbell
Debian – Disabling system beep
Sunday, January 9th, 2005Just installed Debian woody on a P133/16Mb/4gb (actual memory 14Mb, -2Mb for display I guess).
Disable the beep sound of the pc speaker.
Add the following line to ~/.inputrc:
set bell-style none
If the file does not exist, create it.
If the above does not work, add this to the file:
set show-all-if-ambiguous on
Also, I did see here that the inputrc file can be put in /etc. No idea if that works or is relevant.
Will give it a try sometime.
Mandrake Powerpack 10.0 on Dell Inspiron 4150
Thursday, October 28th, 2004Installed Mandrake PowerPack 10.0 on Dell Inspiron 4150.
Specs are <
Performed an “everything” install.
Allowed it to autopartition.
Filesystem Type Size Used Avail Use% Mounted on
/dev/ide/host0/bus0/target0/lun0/part1 ext3 5.8G 3.5G 2.1G 64% /
/dev/ide/host0/bus0/target0/lun0/part6 ext3 31G 38M 31G 1% /home
The NIC – 3Com – was detected.
ATI Display card – with 1600 x 1200 – resolution worked fine.
GNOME worked fine !! which hadn’t worked under Slackware 10.0
Slackware used Gnome 2.4 – which was I guess the latest.
I installed Slack on 3 different machines and 2 different options – normal and expert, but still Gnome would not work. It would load the desktop but no background, Terminal would come up, but not Nautilus.
Wireless Card – Hotplug worked. Network config through the wizard worked fine.
Had to change the SSID for the WLAN.
Driver: Orinoco_cs
USB Mouse as well as the PS/2 touchpad both worked together and alone.
Battery Monitor – in Gnome – worked fine.
Shutting the lid, would put the system in standby and bring it back up without any problems.
Windowmaker, XFCE, all worked fine.
I had not installed KDE, so no idea about KDE.
Menus in MDK 10.0 are much much better than what I had seen in 9.2.
Much better organized, fewer options in each category.
Sound – worked out of the box – ALSA
(Donno the sound card, think it is AC’97)
Pleasant Surprise – Audacity was installed 
Also, Kdenlive was installed – havent had a chance to try it out.
CDROMs are automounted – nice, has been a MDK feature.
an icon appears on the desktop.
USB Drives – work …..although they do not automount. I suppose this
can be set in /etc/fstab.
Not so pleasant things:
XMMS was not installed 
Totem has such a stupid interface for Playlists.
Windows key not mapped to Gnome menu.
Wireless configuration – 2
Thursday, September 30th, 2004Update 2: Sep 30, 2004, 3:14am
Edited the /etc/rc.d/rc.wireless.conf
Changed the ESSID from Any to
Logged out and logged in – no luck.
/etc/rc.d/rc.pcmcia stop , then start – no luck.
reboot – got it working on the reboot…Dunno if it was the manual editing of the file…or the Kwifi manager.
Setting the system-wide default window manager
Thursday, September 30th, 2004Change it in /etc/X11/xinit/
or
use xwmconfig.
or
at the login screen, change the Session to whatever you want.
(This was tested in Slackware 10)

Wireless configuration – related commands
Monday, September 27th, 2004Got the Hawking Wireless card working on Slackware 10 (Dell Laptop).
I cannot say “finally” because I had never tried earlier
Had left the card in the PCMCIA slot during install and it installed drivers or modules for it automatically.
Leaving the card in the slot during installation has nothing to do with it.
It is when the system is rebooting that the Cardbus services are activated and
these devices detected.
Saw that KDE had KWifiManager installed. This KWifi is pretty cool. It shows the signal strength, the access point MAC address,
the IP address. Just like the Windows utility. KWiFiManger simply reports the information being handled by wireless tools. In addition, it also has different configuration profiles too.
It wouldn’t work the first time though after I changed the SSID and activated the configuration.
So I gave it a restart and it worked !
Reboot not really necessary.
I tried this and it worked!
/etc/rc.M
Apparently, this was a re-init of all services for the Multiuser profile,
I guess rc.pcmcia would have done the same.
So that got my Internet working (I saw the IP address was assigned).
It got detected as eth0, which is quite confusing. The onboard NIC became eth1.
In some distro of Linux, I had seen that the wireless connections were referred to by wlan0, wlan1 and so on…
In any case, wireless is working and at last the laptop can be moved out of my room.
It’s only this card that was working and I don’t know how to get the other cards working (as yet).
So here are some commands and snippets I learnt along the way:
/etc/rc.d/wireless – This file is read when initializing the wireless connections when booting up.
Wireless networking is managed via the /etc/rc.d/rc.wireless, /etc/rc.d/rc.wireless.conf and /etc/rc.d/rc.wlan scripts.
Wireless Tools for Linux
http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Tools.html
- iwconfig manipulate the basic wireless parameters
- iwlist allow to initiate scanning and list frequencies, bit-rates, encryption keys…
- iwspy allow to get per node link quality
- iwpriv allow to manipulate the Wireless Extensions specific to a driver (private)
- ifrename allow to name interfaces based on various static criteria

Setting Java Path for Eclipse
Sunday, September 26th, 2004Installed Eclipse 3.0.2 on a Dell Laptop running Slackware 10.0
Installed Java into /usr/local
This link gives a walkthrough to editing the /etc/profile file.
http://www.linuxforum.com/forums/index.php?showtopic=86431
———————————————————————————
Best solution – set both variables for all users:
-remove the addition to /home/danny/.bash-profile (we’ll move it to /etc/profile)
-edit /etc/profile
add:
export JAVA_HOME=/home/danny/Development/Java/j2sdk1.4.2_05
export PATH=$PATH:$JAVA_HOME/bin
Home is not set to ../j2sdk1.4.2_05/jre/bin/java as that is an actual file, and it should be set to the top directory of java.
The PATH is set to incluse $JAVA_HOME/bin instead of $JAVA_HOME/jre/bin/ as I think that the former is the correct java to use for the sdk, though both look the same:
| CODE |
| root@lfs:/opt/j2sdk/j2sdk/bin# ./java -version java version “1.4.2_03″ Java(tm) 2 Runtime Environment, Standard Edition (build 1.4.2_03-b02) Java HotSpot(tm) Client VM (build 1.4.2_03-b02, mixed mode) root@lfs:/opt/j2sdk/j2sdk/bin# cd ../jre/bin root@lfs:/opt/j2sdk/j2sdk/jre/bin# ./java -version java version “1.4.2_03″ Java(tm) 2 Runtime Environment, Standard Edition (build 1.4.2_03-b02) Java HotSpot(tm) Client VM (build 1.4.2_03-b02, mixed mode) |
If it doesn’t work for you then try
export PATH=$PATH:$JAVA_HOME/jre/bin
instead
Once the profile is changed, bash needs to load the profile. You can login again, start another bash session (new console or konsole or whatever) or type:
source /etc/profile
check the settings have taken effect with:
echo $JAVA_HOME
echo $PATH
You may also want to set MANPATH to include $JAVA_HOME/man
export MANPATH=$MANPATH:$JAVA_HOME/man
if your distro uses /etc/man.conf then add the manpath to that instead.
add the line:
MANPATH /home/danny/Development/Java/j2sdk1.4.2_05/man
You mentioned CLASSPATH in the topic, this is from the Beyond Linux From Scratch instructions:
| QUOTE |
Handling CLASSPATH When compiling packages, the CLASSPATH environment variable is used by JDK to locate classes at compile-time and run-time. It is tedious to add all the classes used to the CLASSPATH manually. You may add the following lines to your shell startup file to set CLASSPATH automatically to include all JAR files in a specified directory, which in the example below is /usr/lib/auto-java-classpath. AUTO_CLASSPATH_DIR=/usr/lib/auto-java-classpath
|
so you can modify that to use whatever directory you want to have your classes, and put it into /etc/profile
