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!).

Background

Rss is a wonderful system to get headlines of online news from many independent sources and browse them as quickly as possible, without subscribing to any website, giving away personal information and/or depending on any third-party website to aggregate everything for you.

Yesterday Sergio, a user of OpenOffice Impress, sent to the OpenOffice.org discussion list his list of the “Major Gaps of OpenOffice Impress 3.3 vs. Microsoft Office PowerPoint”.

WordPress is quick and easy to install and update, but the quicker you can make these operations the better, right? If you have shell access to the server where your WordPress copy is installed, it is possible to perform all the operations in Step 1 of the Manual WordPress Update Procedure with the shell script below. It will save you a few minutes, which may seem too little, but is great if you maintain more than one copy of WordPress. That, however, is not the main reason to use a script like this. Its bigger advantage is reducing the possibility of human error by doing things by hand, at the prompt or with the mouse is the same.

Around October 2010 I migrated from Drupal to WordPress my bilingual websites Stop and Strider. Eighteen months later, WordPress has confirmed to be better than Drupal for my own needs, as far as those two websites are concerned (I still stick to Drupal for other websites). There is, however, one part of those WordPress websites that has just become a big problem for me, and is how to keep them (looking) multilingual.

Every now and then, a question like this pops up on some email server management forum:

  I'd like to be able to reject connections from remote IP addresses if they're from certain countries.

The usual reason is either that

Gnuplot is a really great plotting utility, that can be used either interactively or automatically, from inside scripts of all sorts. However, sometimes it can be quite difficult to use simply because there are lots of documentation, but it is hard to figure out exactly what piece of documentation you should read and where it is.

Wordpress is a great publishing system, but managing it manually can be a very time consuming process. This is especially true when you want to upload lots of posts, or if you would like to write content in your preferred, full-blown text editor and then have it “magically” appear online.

Wordpress takes care of these needs
