DNS is a complex system. What you have read so far is just the tip of… the tip of the iceberg. I hope it is enough, however, to help you decide if any of these “DNS hacks” could be useful for you, and show you the road to implement them:
Just a few notes on the purpose, structure of DNS, with some really basic configuration procedures and tricks for DNS on Linux
Static websites are great. Hugo is a really great static website generator. Except for a few things (some not even Hugo’s fault!).
Did you ever cancel by mistake a post on some website, only to find out that you had no other copy of it anywhere, not even in Google’s cache? I did. Here is how I recovered it.
A few tips and tricks, from a thread in the Fedora Users mailing list, on how to “to digitize several hundred music CDs” under any Gnu/Linux distribution
update 2016/07/01 6pm: SOLVED. Details here (but DO read anyway the whole post, because the cause of this problem on your computer may still be one of those below!)
Owners of websites that remained frozen for a year or more, because the _projects _they represent also were closed, or greatly slowed down their activity, face a big problem when those projects restart: updating the website without losing all its old content is really, really hard, if not impossible. Here is how I faced this problem with an old Drupal website, with an approach that can work on many other websites running off some database.
The CentOS 6 Linux Server Cookbook is a Packt Publishing title first published in April 2013. You can buy it in paper format (about 370 pages) or as an ePUB or PDF file (black and white only, whereas the ePUB version is in colours). In general I believe, especially in these times of PRISM and widespread economic crisis, that the more people learn how to run their own Free Software servers, the better. I’ve already explained how and, above all, why we should all do this with email and (at least) social networking and online publishing. That’s why, when Packt asked me to review the Cookbook, I accepted.
update 2012/07/13: I have realized only today that from March 2012 Scratch is also available with a GPL v2 license.
Recently there have been two separate discussions on two italian Free Software mailing lists, about the meaning and obligations of the license for the source code of the educational software Scratch. In both cases, I asked (and received) confirmation of my understanding of the license directly from the “Help@Scratch”. The discussions were about two topics that are, I believe, interesting and relevant for everybody considering usage or development of Free Software, especially (but not only) in educational and non-profit contexts. Therefore, I’m publishing the answers I got from the Scratch team here (with their approval), hoping they may be useful to everybody else with the same doubts in the future (but please see the disclaimer below!).
