clippy() { echo "I see you're trying to use the terminal …"; echo " v "; echo " ╭─╮"; echo " ⌾ ⌾"; echo " │▕│"; echo " ╰─╯"; }
function command_not_found_handle { clippy $1; }

It will result in:

$ adsf
I see you're trying to use the terminal …
v
╭─╮
⌾ ⌾
│▕│
╰─╯

Looks better in the terminal.

Now the windows will focus on hovering the mouse over it.

Set via:
$ gsettings set org.gnome.shell.clock show-date true
$ gsettings set org.gnome.shell.clock show-seconds true

Only follow:
gconftool-2 –type string –set /apps/metacity/general/focus_mode mouse

Also raise:
gconftool-2 –type boolean –set /apps/metacity/general/auto_raise true
gconftool-2 –type string –set /apps/metacity/general/auto_raise_delay 600

Steps:

1. Make sure you don’t use spotify free. It will not work on linux.
2. Install some things: $ sudo yum install qt-webkit perl-ExtUtils-MakeMaker libXScrnSaver nspr-devel openssl-devel
3. For 64 bit, do: $sudo ln -s /usr/lib64/libssl.so /usr/lib64/libssl.so.0.9.8
4. For 32 bit, $ sudo ln -s /usr/lib/libssl.so /usr/lib/libssl.so.0.9.8
5. Find the latest spotify deb. At the time I write this, this is located here. Find the latest version here.
6. Convert the .deb to .rpm using Alien. Instructions here. It will create a .rpm
7. Install : $ sudo rpm -Uvh –nodeps /path/to/your/rpm

If it complains about .so files not existing:

1. For example, it looks for ‘libsmime3.so.1d’
2. Search for ‘libsmime3.so’ in your lib-dir. For 64-bit, this is /usr/lib64. For non-64-bit, it is probably /usr/lib/: $ ls /usr/lib64/libsmime3.so
3. Symlink this to the file spotify is searching for: sudo ln -s /usr/lib64/libsmime3.so /usr/lib64/libsmime3.so.1d
4. Repeat this about 10 times. Maybe you can find all the missing links by soing this: $ ldd /usr/bin/spotify | awk ‘{print $1}’ | xargs ls 1>/dev/null

If you get a segfault:

• I got a segfault (segmentation fault) with the native linux client, solved by using a later build. Find the latest one at one of the links above
• Find out why it segfaults by using $ldd spotify , enter ‘run’ and you will get output

Error 409 means you need a subscribtion.

If spotify crashes at startup, clear the caches:  $ rm -r {.cache,.config}/spotify

Symlinks I made:

cd /usr/lib64
sudo ln -s libnss3.so libnss3.so.1d
sudo ln -s libnssutil3.so libnssutil3.so.1d
sudo ln -s libsmime3.so libsmime3.so.1d
sudo ln -s libplc4.so libplc4.so.0d
sudo ln -s libnspr4.so libnspr4.so.0d
sudo ln -s /usr/lib64/libssl.so /usr/lib64/libssl.so.0.9.8
sudo ln -s libcrypto.so libcrypto.so.0.9.8

$ find /home/karlo/temp/ -type f -mtime +5 -delete && find /home/karlo/temp/ -empty -delete

You now have a folder ‘DropboxSecure’, in which you can store your sensitive data. It will save this in ~/Dropbox/Secure/ .

You can unmount this via $ sudo umount /home/karlo/DropboxSecure #needs to be done using sudo. I guess this is a bug. After umounting, you will notice the directory DropboxSecure is still there, but empty.

Mount again by using step 3 and entering your password.

Paranoia settings:

Each file contains 8 byte header with unique IV data.

File holes passed through to ciphertext.

Screenshot:

It works very good. I use it like this:

$ redshift -l 52.369:4.891 #amsterdam

http://www.openstreetmap.nl/ can give you your coordinates.

Setting up is easy. It is just a CGI script. So place it in your CHI-folder (or create one) and  set the directory-settings so it will allow CGI scripts. Sample config is in the download.

You can use this to configure your own working SSL mail. Remember to install: dovecot, dovecot-imap and postfix.

On your devices, use ports 143/993 (incomping) and 587 (outgoing).

Please note my main.cf file also includes config for mailman.

$ sudo service dovecot restart
* Restarting IMAP/POP3 mail server dovecot
Error: mail_executable: Can’t use /usr/lib/dovecot/imap: No such file or directory
Fatal: Invalid configuration in /etc/dovecot/dovecot.conf
…fail!

install dovecot-imap

You can now update via ‘update now’.

#!/usr/bin/php
<?php

for( $i=0; $i<99; $i++ ){
echo “Will try [$i] now. \n”;
$mbox = imap_open(“{mail.mailserver.com:143/imap/novalidate-cert}INBOX”,”user_test_$i”,”foobar”,0,0);
}

?>

Edit: You will need php-cli and php-imap

Deprecated Linux networking commands and their replacements 

I mostly use $ifconfig. Let’s try `$ ip a` from now on .
