“Resilience arises from a rich structure of many feedback loops that can work in different ways to restore a system even after a large perturbation.
A single balancing loop brings a system stock back to its desired state.
Resilience is provided by several such loops, operating through different mechanisms, at different time scales, and with redundancy-one kicking in if another one fails.”“And, conversely, systems that are constant over time can be unresilient.
This distinction between static stability and resilience is important. Static stability is something you can see; i's measured by variation in the condition of a system week by week or year by year. Resilience is something that may be very hard to see, unless you exceed its limits, overwhelm and damage the balancing loops, and the system structure breaks down. Because resilience may not be obvious without a whole-system view, people often sacrifice resilience for stability, or for productivity, or for some other more immediately recognizable system property.” -

You see self-organization in a small, mechanistic way whenever you see a snowflake, or ice feathers on a poorly insulated window, or a supersaturated solution suddenly forming a garden of crys-tals. You see self-organization in a more profound way whenever a seed sprouts, or a baby learns to speak, or a neighborhood decides to come together to oppose a toxic waste dump”

“Self-organization produces heterogeneity and unpredictability. It is likely to come up with whole new structures, whole new ways of doing things.
It requires freedom and experimentation, and a certain amount of disor-der. These conditions that encourage self-organization often can be scary for individuals and threatening to power structures. As a consequence, education systems may restrict the creative powers of children instead of stimulating those powers. Economic policies may lean toward supporting established, powerful enterprises rather than upstart, new ones. And many governments prefer their people not to be too self-organizing.” -

The daily news tells of elections, battles, political agreements, disasters, stock market booms or busts. Much of our ordinary conversation is about specific happenings at specific times and places. A team wins. A river floods. The Dow Jones Industrial Average hits 10,000. Oil is discovered. A forest is cut. Events are the outputs, moment by moment, from the black box of the system.”

“standing. When a systems thinker encounters a problem, the first thing he or she does is look for data, time graphs, the history of the system. That's because long-term behavior provides clues to the underlying system struc-ture. And structure is the key to understanding not just what is happening, but why.”

“The lesson of boundaries is hard even for systems thinkers to get. There is no single, legitimate boundary to draw around a system. We have to invent boundaries for clarity and sanity; and boundaries can produce problems when we forget that we've artificially created them.”

“It's a great art to remember that boundaries are of our own making, and that they can and should be reconsidered for each new discussion, problem, or purpose. It's a challenge to stay creative enough to drop the boundaries that worked for the last problem and to find the most appropriate set of boundaries for the next question. It's also a necessity, if problems are to be solved well.”

“There always will be limits to growth. They can be self-imposed. If they aren't, they will be system-imposed. No physical entity can grow forever. If company managers, city governments, the human population do not choose and enforce their own limits to keep growth within the capacity of the supporting environment, then the environment will choose and enforce limits.”

Migliaia di persone sono confluite nella simbolica piazza Enghelab a Teheran dopo l'annuncio della morte della Guida suprema Ali Khamenei. Per lo più vestiti di nero, alcuni in lacrime, e sventolando ritratti di colui che era al potere in Iran dal 1989, i manifestanti hanno scandito "Morte all'America!", "Morte a Israele!" tra le bandiere della Repubblica islamica.

@rubenerd maybe a question mark?

Today is my grandfather’s birthday. He would have turned 99, and he was the one who inspired the #FediMeteo project.
Happy birthday, Grandpa.

@quinta Eh, ‘nzomma…
Intanto perché quelli di Graphene sono in continua polemica con eOS accusandoli di essere al soldo del governo francese (ah ‘a community, quant’è bell’a community) e poi perché Motorola = Lenovo = Cina.
Che la Cina stia approfittando dell’implosione USA lo sappiamo, non sono convintissimo che togliere le palle dalle mani USA per passarle a quelle CN sia un grosso passo avanti.
Dovremmo spingere per una piattaforma europea, hardware compreso.
E meno fuoco amico.

@peterkotrcka The first part is ok. The second isn't totally clear.

Prosegue l'operazione congiunta Usa‑Israele avviata ieri per abbattere il regime iraniano. Nei raid è stata uccisa la Guida suprema Ali Khamenei, dubbi invece sulle sorti dell'ex presidente Mahmoud Ahmadinejad. I Pasdaran hanno minacciato l'operazione "più feroce" della storia contro Israele e le basi statunitensi. Il presidente Usa Trump: "Se l'Iran colpirà duro, reagiremo con una forza mai vista prima". E ancora: "L'operazione durerà quattro settimane”.
