Ubuntu EOL (End-Of-Life)

If you only need access to some old repositories the only step you need to apply is adding/editing few lines in /etc/apt/sources.list.

## EOL upgrade sources.list
# Required
deb http://old-releases.ubuntu.com/ubuntu/ CODENAME main restricted universe multiverse
deb http://old-releases.ubuntu.com/ubuntu/ CODENAME-updates main restricted universe multiverse
deb http://old-releases.ubuntu.com/ubuntu/ CODENAME-security main restricted universe multiverse

# Optional
#deb http://old-releases.ubuntu.com/ubuntu/ CODENAME-backports main restricted universe multivers

Now just execute apt-get update and you can use those repositories.

How to check if a processor is capable of 64-bit.

If you are running Linux, open the terminal prompt and run:

grep --color=always -iw lm /proc/cpuinfo

If this command returns lm (Long Mode) as one of the flags, then your processor is capable of 64-bit.

Wireshark match operator

matches   Does the protocol or text string match the given Perl regular expression?

fix.MsgType == "D" and fix.SecurityDesc matches "CLT|NGT"


The "matches" operator allows a filter to apply to a specified Perl-compatible regular expression (PCRE). The "matches" operator is only implemented for protocols and for protocol fields with a text string representation.

More information on PCRE can be found in the pcrepattern(3) man page (Perl Regular Expressions are explained in http://perldoc.perl.org/perlre.html).

Vim color scheme

I always forgot this:

In gvim, after changing the default color scheme, the next time gvim is started, the default setting is restored.
To retain the color scheme add colorscheme <scheme_name> to vimrc.
For example:
colorscheme murphy
