Fabrizio de André - Il testamento di Tito

Also from Fabrizio de André, Il testamento di Tito, inspired on the New Testament, in which one of the two thieves that were crucified together with Jesus comments on the 10 commandments, on point of death on the cross.

This is one of my favourite songs of De André, if not one of my favourite songs ever. To me it celebrates how laws that at first glance may seem reasonable, cannot be absolute when facing the diversity of the world.

Here are lyrics with translation. I think there should be a New New Testament, made just with the lyrics of this song.

Fabrizio de André - Il Gorilla

The first song is Fabrizio de André's version of Brassens' Le Gorille: Fabrizio de André, Il Gorilla.

Like Brassens, De André was also an anarchist, and translated many of his songs.

It's also available in Milanese, sung by Nanni Svampa.

An Italian song a day

Last year me and some other friends played the game of suggesting an Italian song a day for a friend had recently moved to Italy.

I've started cleaning up the song list, and turning it into a series of posts. Enjoy!

On Progress and Historical Change [archive]
«Is progress inevitable? Is it natural? Is it fragile? Is it possible? Is it a problematic concept in the first place? Many people are reexamining these kinds of questions as 2016 draws to a close, so I thought this would be a good moment to share the sort-of “zoomed out” discussions the subject that historians like myself are always having.»

Vatican Climate Forest [archive]
«The Vatican Climate Forest, to be located in the Bükk National Park, Hungary, was donated to the Vatican City by a carbon offsetting company. The forest is to be sized to offset the carbon emissions generated by the Vatican during 2007. The Vatican's acceptance of the offer, at a ceremony on July 5, 2007, was reported as being "purely symbolic", and a way to encourage Catholics to do more to safeguard the planet. No trees have been planted under the project and the carbon offsets have not materialised.» I'm fascinated by how purely symbolic "purely symbolic" can be.

Modern and secure instant messaging

Conversations is a really nice, actively developed, up to date XMPP client for Android that has the nice feature of telling you what XEPs are supported by the server one is using:

Initial server features

Some days ago, me and Valhalla played the game of trying to see what happens when one turns them all on: I would send her screenshots from my Conversations, and she would poke at her Prosody to try and turn things on:

After some work

Valhalla eventually managed to get all features activated, purely using packages from Jessie+Backports:

All features activated

The result was a chat system in which I could see the same conversation history on my phone and on my laptop (with gajim)(https://gajim.org/), and have it synced even after a device has been offline,

We could send each other rich media like photos, and could do OMEMO encryption (same as Signal) in group chats.

I now have an XMPP setup which has all the features of the recent fancy chat systems, and on top of that it runs, client and server, on Free Software, which can be audited, it is federated and I can self-host my own server in my own VPS if I want to, with packages supported in Debian.

Valhalla has documented the whole procedure.

If you make a client for a protocol with lots of extension, do like Conversations and implement a status page with the features you'd like to have on the server, and little green indicators showing which are available: it is quite a good motivator for getting them all supported.

Teamwork

When I saw this video or this video I thought of this article.

When I feel part of a tightly coordinated and synchronized team I feel proud for the achievements of the team as a whole, which I see as bigger than what I could have achieved alone.

I also don't feel at risk of taking bad decisions. I feel less responsible. If I do what I'm told, I can't be blamed for doing the wrong things. I find it relaxing, every once in a while, to not have to be in charge.

I guess this could be part of the allure of a totalitarian regime: being freed from the burden of growing up

Thinking about this, reading those articles about romantic relationships, I see quite a bit of parallels also with organising cooperation and teamwork.

It looks like I ended up making parallels between Polyamory, Anarchism, and Free Software again. If you think there should traditionally be also a mention of BDSM, go back to "I find it relaxing, every once in a while, to not have to be in charge".

"Intervallo RAI" generator

During holiday idling, I made a thing to generate picture slideshows similar to RAI's iconic "Intervallo"

You can get it at https://github.com/spanezz/intervallo

Usage:

$ intervallo --help
usage: intervallo [-h] [--font file.ttf] [--audio file.mp3] [--duration sec]
                  imgfile [imgfile ...]

Create an Intervallo RAI out of a collection of images.

positional arguments:
  imgfile           input image files

optional arguments:
  -h, --help        show this help message and exit
  --font file.ttf   Font to use for subtitles
  --audio file.mp3  Audio track
  --duration sec    Time for each image in seconds

For example:

./intervallo --font DejaVuSerif.ttf --audio Paradisi-Toccata.mp3 *.jpg

The images are captioned with their file name, without extension. You may want to rename the image files to have nice descriptive names.

For some audio to use, you can try https://archive.org/details/IntervalloRai-Paradisi

German Cities Are Solving The Age-Old Public Toilet Problem [map]
«City governments are paying local businesses to open up their restrooms to the public. … The program, called Nette Toilette or Nice Toilet, is active in 210 cities and has been running since 2000. Cities pay from $34 to $112 per month to a business, and it puts a sticker in its window to tell people that they can come in and pee for free. … Bremen, a city with a population of over half a million people, reckons it saves $1 million per year by using the network, which costs it $168,000 per year. So successful is the scheme that it has given Bremen the best ratio of public toilets to citizens in Germany.»
