ip_compact and ip_diff

Somehow I always end up working with lists of IP networks and needing to minimize and compare them.

Some of my Perl scripts for this might still be hidden in a corporate source repository, and somewhere in the backups of my old Linux laptop should be even earlier attempts in Bash.

Both of them are not very useful to me where they are, thus I've written yet another version.
This time in Go using the ipaddr package.

Say hello to ip_compact and ip_diff :-)

This Page is Designed to Last

This Page is Designed to Last — a manifesto from Jeff Huang for preserving content on the web, where he advocates to keep content on the web available and pledges to keep his site available for the next 10 years.

Having my content in this weblog online since 2002, I can very much relate to this initiative and additionally would like to point to the efforts of archive.org (aka. The Internet Archive).
The wayback machine of archive.org allows to see old versions of websites, even when the website itself is no longer available.

For me personally this became critically useful when the database of my weblog vanished with no current backup and I then used the archived versions from archive.org to restore the missing content.

Thus I would like to encourage everyone to support the efforts of archive.org with a donation.

New Year - New Vim Trick

Happy 2019! I have learnt a new Vim trick:
When searching for some pattern with / (eg. /mystring), often the next step is to perform a replacement command. Now instead of re-typing the whole string, you can directly enter the substitution command with an emtpy search-pattern (:%s//newstring/), Vim then automatically re-uses the previous search pattern.
