Fault tolerance is the property that enables a system to continue operating properly in the event of the failure of (or one or more faults within) some of its components. If its operating quality decreases at all, the decrease is proportional to the severity of the failure, as compared to a naively designed system, in which even a small failure can cause total breakdown. Fault tolerance is particularly sought after in high-availability or life-critical systems.
Within the scope of an individual system, fault tolerance can be achieved by anticipating exceptional conditions and building the system to cope with them, and, in general, aiming for self-stabilization so that the system converges towards an error-free state.

When Death Comes
When death comes
like the hungry bear in autumn;
when death comes and takes all the bright coins from his purse
to buy me, and snaps the purse shut;
when death comes
like the measles-pox;
when death comes
like an iceberg between the shoulder blades,
I want to step through the door full of curiosity, wondering:
what is it going to be like, that cottage of darkness?
And therefore I look upon everything
as a brotherhood and a sisterhood,
and I look upon time as no more than an idea,
and I consider eternity as another possibility,
and I think of each life as a flower, as common
as a field daisy, and as singular,
and each name a comfortable music in the mouth
tending as all music does, toward silence,
and each body a lion of courage, and something
precious to the earth.
When it’s over, I want to say: all my life
I was a bride married to amazement.
I was the bridegroom, taking the world into my arms.
When it is over, I don’t want to wonder
if I have made of my life something particular, and real.
I don’t want to find myself sighing and frightened,
or full of argument.
I don’t want to end up simply having visited this world.
In fact, it’s Dougie’s growing conviction that the greatest flaw of the species is its overwhelming tendency to mistake agreement for truth. Single biggest influence on what a body will or will not believe is what nearby bodies broadcast over the public band. Get three people in the room and they will decide that the law of gravity is evil and should be rescinded because one of their uncles got shit-faced and fell off the roof.
That means not catching this killer flu.
“Wash your hands. Don’t be complacent. This will be going on for a while. You have to be disciplined.”
The Brazilian president, Jair Bolsonaro, is the only world leader widely believed not only to have Covid-19 and to have lied about it but to have knowingly spread it to untold numbers of his followers…. Under quarantine after his return from the US — 25 members of his entourage have been infected with coronavirus, making Bolsonaro the center of the largest initial cluster in Brazil — the president broke out of his motorcade to shake hands and high five those calling for the government buildings to be burnt to the ground.***Bolsonaro’s approach to Trump is monkey see, monkey do, so the day after Trump floated the idea of an early return to work, against the advice of leading military figures, Bolsonaro went on national television to announce that (in his experience?) coronavirus was just ‘a little flu’, and that since old people rather than children were dying in other countries, Brazilian children should return to school and young people should return to work. Businesses were to reopen, since the politics of quarantine was ‘a thing for cowards.’ According to the speaker of the lower house, Rodrigo Maia, Bolsonaro was under pressure from investors after the market in São Paulo crashed, losing 52 percent of its total value between 17 January 17 and 20 March — the biggest drop in the world, according to Goldman Sachs.In addition to the number of coronavirus cases and deaths (as of 26 March, 2915 and 77 respectively), Brazil is also leading Latin America in capital flight: Mexico has lost $2 billion in foreign investment; Brazil has lost $12 billion. The real, meanwhile, has dropped to a new low of $5.02 to the dollar. The economy minister, Paulo Guedes, who studied under Milton Friedman at the University of Chicago and at the University of Chile under Pinochet, warned Bolsonaro that Brazil could not afford to quarantine beyond 7 April; the country was already in recession before Covid-19 arrived. To informal workers, who make up four-fifths of the economically active population in urban settlements (favelas), where at least 13.6 million people live, Guedes is offering 200 reals in vouchers, which will not be enough to keep them from having to work to survive.
I really have very little to steal, but losing this laptop for me would be catastrophic.
Your action in the situation at hand
Must be accomplished with mindfulness
And a gentle hand;
Any other way misses the point.
This time is well represented by the Hermit card in the tarot, which signifies that there is a guiding light on your path, but you are walking it alone. It is a time to be solitary, to meditate, organize, and find the truth in your heart. During this time of solitude, feelings of agitation or frustration will arise. No worries, no blame. These feelings will pass as you deconstruct them and shift the fear to love. Clarity, understanding, and enlightenment await you on the journey. Give your mind a break and relax into this in-between state.
[T]he way the coronavirus disproportionately affects older people is the exact way the climate crisis disproportionately affects young people. … This pandemic has brought business as usual to an official halt. When the worst of the illness has passed, instead of rushing to return to “normal” — the old, comfortable pattern of destroying the planet — we can take this opportunity to restructure our economy and society in a way that will ensure today’s children can live.
Wilma … escalated from a tropical storm to a category five hurricane in 24 hours — the strongest hurricane ever to have gestated in the Atlantic. It passed over the island of Cozumel and moved north, taking with it most of Cancun’s 24,000 hotel rooms and almost all of its beach. A hurricane like this would typically be expected to last around four hours. Wilma lasted 64.And yet there was not a single death. This is the most important point about Wilma’s assault on Mexico: though 62 deaths were reported after Wilma in Cuba and Florida, none were reported here. In a country whose pride is often wounded by the superiority complex of its northern neighbor, the response to Wilma stands in crucially stark contrast to that of the US government to Katrina, which caused almost 2,000 fatalities.Although Wilma gathered strength with unprecedented speed, the Mexican government was prepared. Everyone in the region was evacuated; shelters were ready; President Fox ordered the military to be on hand with helicopters and food. The Red Cross was there with first aid. The electrical company was sent down in advance in order to repair the damage as quickly as possible once Wilma was over.
Many will be tempted to see the tragic coronavirus pandemic through a solely partisan lens: The Trump administration spectacularly failed in its response, by cutting funding from essential health services and research before the crisis, and later by denying its existence and its severity. Those are both true, but they don’t fully explain the current global crisis that has engulfed countries of varying political persuasions.
As it turns out, the reality-based, science-friendly communities and information sources many of us depend on also largely failed. We had time to prepare for this pandemic at the state, local, and household level, even if the government was terribly lagging, but we squandered it because of widespread asystemic thinking: the inability to think about complex systems and their dynamics. We faltered because of our failure to consider risk in its full context, especially when dealing with coupled risk — when multiple things can go wrong together. We were hampered by our inability to think about second- and third-order effects and by our susceptibility to scientism — the false comfort of assuming that numbers and percentages give us a solid empirical basis. We failed to understand that complex systems defy simplistic reductionism.
Widespread asystemic thinking may have cost America the entire month of February, and much of what we’d normally consider credible media were part of that failure.
Holbox y los extranjeros….
Holbox and foreigners …. it is in conditions like these where you can show the best or the worst of yourselves. While Cuba sends doctors to Italy and receives foreign patients with Covid 19, the United States refuses them entry and tries to steal the development of German vaccines for their exclusive use. In this crisis you decide if you are proud of having been supportive or selfish without empathy. On the island there is not a single type of foreigners; there are those who have been working here for years, those who have been here several months, and the gigantic majority have been here for more than 15 days, so they are not a contagion factor. We have known that medical services have been deficient on the island for years, but no population in the world has the number of respirators necessary for a possible pandemic. It is not something specific to the island. The 10% with serious symptoms should go to Cancun, whether foreign or national. There are almost no flights and many borders are closed when someone is expelled from the island they are unnecessarily exposing them. It is likely that a year from now a large majority will have had the virus, some without realizing it. Protect your loved ones at risk, take responsibility for your own health with better food and exercise, and we will come out with our heads held high. Come on Holbox, don’t let fear stain your essence.
“…it is vital that we keep in mind just how much more destructive climate change could be for all of us…. Because there is one huge difference between the coronavirus and climate change: Climate change doesn’t “peak” — and then flatten out and then maybe dissipate or be permanently prevented by vaccine — so normal life resumes…. There is no herd immunity to climate change. There are only endless impacts on the herd.”
