Weird/confusing name, questionable legality and the website went down a while back (while mentioned explicitly in the licence…)
Use CC0 1.0 or Zero Clause BSD instead. They are more reputable, and all decent “public domain equivalent” licences are… well, equivalent in effect, anyway.
CC0 is the one CC licence you can safely use for code, as per the official recommendations. For all other CC licences, it is (strongly) discouraged.
RE: Copyleft
The idea of copyleft is that you give anyone the freedom to do anything with your work, with one essential restriction: they do the same for their changes, derivative works etc. Technically attribution doesn’t have to be part of a copyleft licence, but all copyleft licences I know have a requirement to preserve copyright info.
And yes, it is popular in software (GPL, MPL, EPL), but for other types of works there is CC BY-SA 4.0 (Creative Commons Attribution-ShareAlike). If you want to copyleft books, images, videos, other forms of text… this is the way to go, IMO.
Some additional remarks, just to clarify:
The Wizard Book is a classic that basically “builds” programming as a concept.
(it is very technical though. So not sure it’s something you’re looking for)
This has existed for a while and can be used by anyone: https://github.com/ggerganov/kbd-audio
There’s a difference between making a vim reference and “oh, a mourning family message? quick, i must find a stale joke to crack for internet points”
Feel free to tell yourselves this is respectful. I think some people here have been on the internet for too long.
Poor taste.
Ask around
All right. Do you know any for any European country?
Pricing is still relevant, at least in Europe (from my experience). I’ve done a lot of low-budget traveling with small groups of students in France this year, and AirBnB was (unfortunately) consistently and significantly less expensive than hotels.
Also, many hotels don’t give you access to a kitchen, which really sucks if you don’t want to spend money eating out every day.
The more important thing: anyone can see their posts now. This is rather crucial for a government institution’s feed and not true on Twitter anymore.
