Reading “Thinking in Systems”
“Purposes are deduced from behavior, not from rhetoric or stated goals”
We often get stuck on what is said and forget to look at results. If the results never match what is said then you need to realize maybe what is said is meant to mislead. It could also be lack of skills but that is not much better.

“sub purposes could come in conflict with the overall purpose”
“Keeping sub purpose and the overall purposes in harmony is an essential function of a successful system”

“The human mind seems to focus more easily on stocks (levels of a good) than on flows. On top of that, when we do focus on flows, we tend to focus on inflows more easily than on outflows”
“Everyone understands that you can prolong the life of an oil. based economy by discovering new oil deposits. It seems to be harder to understand that the same result can be achieved by burning less oil.”

“In fact, just about any long-term model of a real economy should link together the two structures of population and capital to show how they affect each other. The central question of economic development is how to keep the reinforcing loop of capital accumulation from growing more slowly than the reinforcing loop of population growth—so that people are getting richer instead of poorer.”

“The real choice in the management of a nonrenewable resource is whether to get rich very fast or to get less rich but stay that way longer.”

@shafik Sometimes I call this "lying or incompetent"

“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.” -

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.”

@quinta questa partnership risolverà anche il problema del Play Integrity check? (MEETS_STRONG_INTEGRITY)

@DigiDavidex immagino che quel display sia programmabile dinamicamente.
Potresti prevedere delle frasi legate alla temperatura del processore.
Ad esempio "Cazzo che freddo" per T < 40°C, "Si sta quasi benino" per T compresa tra 40 e 70°C e "Boia de' che caldo" per T > 70°C.
Punti bonus se si può anche scegliere il colore dei LED.

@jorge @fosdembsd @HisVirusness you're right! I had missed that when switching language. There is in French, though, so I can share it with my in-laws 😅 https://fr.wikipedia.org/wiki/Slop_(intelligence_artificielle)
I wish I knew how to create/edit Wikipedia entries because my family and their friends often share AI slop and I had to educate my mom and dad about it...

Dentro la mente di Epstein
Una mail, auto-spedita nel 2016, in cui Epstein si auto addestra sulle cose che deve dire e pensare, a proposito delle indagini e delle tante denunce su di lui

@paride5745 I did it in the past. Some providers were good enough to stop those things quite soon. Others just didn't care. The last time I tried, Azure didn't care at all...

sto a vedere come si dipana, che la prossima sostituzione potrebbe rivelarsi problematica. e sempre sperando che quelli di GOS rimangano puliti.

@stefano when I worked for rackspace in 2013 we used to notify the IP owners of abuse activity. Pretty much all public clouds forbid port scanning, I would be surprised if nothing happens.
