Basically, a purpose built building with 30-50 small apartments and social services co-located. Residents have to meet conditions to get in, to remain in and progress to the point that they can function in more regular market housing, thus freeing the slot for another resident.

' Our supportive living units are run in partnership with other organizations and provide specialized supports for individuals exiting homelessness. This includes substance use support, mental health care, and peer support. Our programs are designed to be client-centred with a harm-reduction-focus. [...] Carruthers is a supported housing program operated in partnership with the John Howard Society with 46 units. Originally, the substance use treatment available focused strongly on Injectable Opiate Substitution (IOAT) with 20 of the available apartments being reserved for people who were enrolled in that program. Many of the original residents have now migrated to other forms of treatment and to different lives where volunteering, work and time spent with family and friends are a priority. [..] The Richcraft Residence was the first OICH housing program which offered all available substance use, physical health and mental health treatments in one location providing a full menu of care options for residents. '

Upstream of supportive housing you need good street facing services with social workers and police well coordinated and tracking clients.

Downstream of supportive housing you need to help people maintain the progress they made at living more indepently as a functional part of their wider community.

Remaining problems include:

- keeping clients alive long enough to recover before they die from opiod poisoning

- having enough of supportive housing capacity to meet the need.

- the candidates who do not want to participate, even space was available.

" And AT&T continued to improve the technology at work in its infrastructure. The transistor, invented at Bell Labs in 1947, eventually allowed for digital, solid-state switching technology to replace electromechanical switches. "

" PURPOSE 1, a Phase 3, double-blind, randomized study, is evaluating the safety and efficacy of twice-yearly, subcutaneous lenacapavir for pre-exposure prophylaxis (PrEP) and once-daily oral Descovy® (emtricitabine 200mg and tenofovir alafenamide 25mg; F/TAF) in more than 5,300 cisgender women and adolescent girls aged 16-25 across 25 sites in South Africa and three sites in Uganda. The drugs are being tested in parallel, with one group receiving twice-yearly lenacapavir and one group taking once-daily oral Descovy. Additionally, a third group was assigned once-daily oral Truvada. Study participants were randomized in a 2:2:1 ratio to lenacapavir, Descovy and Truvada, respectively. Because effective PrEP options already exist, there is broad consensus in the PrEP field that a placebo group would be unethical; thus, the trial used bHIV as the primary comparator and Truvada as a secondary comparator.

There were 0 incident cases of HIV infection among 2,134 women in the lenacapavir group (incidence 0.00 per 100 person-years). There were 16 incident cases among 1,068 women in the Truvada group (incidence 1.69 per 100 person-years). The results demonstrated superiority of twice-yearly lenacapavir over bHIV (primary endpoint, incidence 2.41 per 100 person-years) and superiority of twice-yearly lenacapavir over once-daily Truvada (secondary endpoint), with p<0.0001 for both endpoints. In the trial, lenacapavir was generally well-tolerated and no significant or new safety concerns were identified.

[...]

Gilead expects results in late 2024/early 2025 from the program’s other pivotal trial, PURPOSE 2, which is assessing twice-yearly lenacapavir for PrEP among cisgender men who have sex with men, transgender men, transgender women and gender non-binary individuals who have sex with partners assigned male at birth in Argentina, Brazil, Mexico, Peru, South Africa, Thailand and the United States.

1. When an AI system performs a task, human observers immediately estimate its general competence in areas that seem related. Usually that estimate is wildly overinflated.

2. Most successful AI deployments have a human somewhere in the loop (perhaps the person they are helping) and their intelligence smooths the edges.

3. Without carefully boxing in how an AI system is deployed there is always a long tail of special cases that take decades to discover and fix. "

> They are getting 10 per second. They are nuclear engineers and I'm just a guy who knows how to multiply and how to read wikipedia. Most likely their number is correct.

Nicely done! It gets complicated, well beyond my current understanding. However, U238's first decay product is Thorium234, which has a half life of 24 days. Thorium234 in turn decays into Proactinium, which has a half life of 1.17 minutes. There are 16 more decays until finally arriving at Pb206 (lead), which is stable.

These decays must give room for lots more neutrons to emerge.

The researchers showed that if the amount of matter is negligible compared to the amount of dark energy, then the singularity can be eliminated. “Light rays can actually go through the boundary,” Quintin said. “And in that sense, you can see beyond the boundary; it’s not like a brick wall.” The universe’s history would extend beyond the Big Bang.

However, cosmologists think that the early universe had more matter than energy. In this case, the new work shows that the BGV singularity would be a real physical curvature singularity, at which the laws of gravity stop making sense.

A singularity hints at the fact that general relativity can’t be a complete description of the basic rules of physics. Efforts to form such a description, which would require reconciling general relativity with quantum mechanics, are ongoing. Ling said he sees the new paper as a stepping stone to such a theory.

Now that I’m fairly old, I can look back on a wide range of visions of the 21st century, many of which now seem obsolete. Here are just a few examples:

I recall the 1960s as being a period of techno-optimism. There were visions of a 21st century filled with space travel, supersonic airliners and flying cars.

The mood became more pessimistic during the 1970s. The famous Club of Rome report warned of overpopulation and resource depletion.

In the early 1990s, there was optimism that “The End of History” would usher in an age of peaceful democratic capitalism.

Late in the 1990s, worry increased that the 21st century would see dramatically rising global temperatures.

In the early 2000s, “The Clash of Civilizations” view became trendy, with a special focus on the clash between the West and the Muslim world.

Around 2010, there was an increasing view that this would be the Chinese Century.

A few years later, there were increasing fears of secular stagnation.

Today, people worry about the rise of nationalism, falling birthrates, and fear of unaligned AI.

What do all of these visions have in common? The only unifying thread that I can see is that they all reflect what was going on at the moment.

[...]

I won’t try to predict the future course of the 21st century, but I will try to predict the future course of 21st century predictions. Ten years from now, I expect the consensus forecast for remainder of the century will largely reflect the headline news stories of the 2030s. I predict that in the 2040s, forecasts for the remainder of the century will largely reflect the headline news stories of that decade. Ditto for the 2050s. What will those news stories be? I have no idea. But I strongly believe that predictions of the future will continue to reflect current events, and will mostly not reflect the actual future that plays out over time.

In other words, expect the unexpected. And then expect people to assume that the unexpected will become the new norm, until it is superseded by some other unexpected event.

Alexander did inherit a superb army. However, while he was present the army enjoyed spectacular operational and battlefield success. Once Alexander was gone, the successes also stopped.

In order to do his job, Stonecipher undertook to rationalize and simplify and render legible the firm. Lacking access to "soft information" that could only come from developing relationships within Boeing over years of collaboration, he sought to manage the firm on the basis of "objective" so-called hard information. Among the most salient hard information in any business enterprise is cash flows, so the sway of "bean counters" was elevated automatically. Among the least legible information in a firm, to an outsider, is the quality of employee judgment calls, so internal expertise was demoted. "

" Stress is the feeling one gets when there is so much to do that it can't be done without cheating. For most people, cheating is unpleasant. In order to get the courage to cheat, we need another unpleasant feeling to whip us into it. And that feeling is called stress.

Stress is what we experience when we have too many deadlines to meet too soon. We know that something must go. But we don't know what. So the feeling of stress becomes a perpetual spur to cheat with small things. Maybe work can't be sacrificed. But cooking can. So stressed people eat sandwiches and drink Coke although they know they will feel bad from it in the long term. They avoid double-checking details they know they should be double-checking and hope to get away with it. They know they should be friendly to people around them, but they cheat with that too, because they know they will get away with it, for a while at least. [...] having realized that stress is essentially about cheating, I had the key to stop feeling stressed in everyday life: Only set ridiculously realistic and flexible goals for myself. Decide exactly what I want to do with the time and energy I have and do that and nothing else.

Humans in general want to do more than they are able to do. That is only natural. The opposite, wanting to do less than one is technically capable of doing is called depression. That is not a nice feeling. So the first step towards not being stressed is accepting that if ambitions are higher than ability, that is just a sign of mental health.

Step 2 is to choose consciously among those ambitions. This is hard, because it requires giving up on parts of one's identity. I want to be a person who works hard, keeps physically in shape, spends time with my children, reads books, writes about what I read, maintains a home with a certain standard of maintenance and cleanliness, has many children, wears clothes that are not visibly worn out… I want all that. And I can't achieve all that. I have to choose.

The choice can be made two ways:

1. Consciously and calmly making priorities: What is important and what is less important? What needs to be done right now and what can be saved for later? What should I simply skip?

2. Unconsciously and chaotically. Try to do everything that would be nice to do, and cheat constantly in the process. "

- the land underneath the home, which can be expensive or cheap, depending on location. Land costs are consistently in the order of 25% of the total cost.

- construction costs tend to be higher in more expensive locations (New Tork City)

- financing costs, $12K

- real estate/marketing fees, $27K

- builder profit, $60K

- permits and inspections, $19.2K

- architecture and engineering, $5K

Most significant is that about 125 million Americans live in a place where the land cost is more than 50% of the total cost and 16 million live in a place where the land share is greater than 70%.

In those places, lower costs come from allowing greater density, which divides the land cost among a much greater number of housing units.

The animals learned about the humans as well. For instance, walking to the back edge of the farm in the fall to fix fencing, the cows would change their routine to follow - especially the part were you might route through the field full of apple trees.

Sure enough, you'd see that the cows had eaten all the apples they could reach but there were vast quantities of ripe apples higher up. So you climbed the tree and used your legs to shake branches, causing bushels of apples to thunder down. The cows that had followed would call loudly to summon their herd mates, who would come at the run.

If the sheep saw me on the same trip, I'd be ignored...unless I was carrying a bucket, which meant it probably had oats, at which point I'd have a herd of sheep converging on my position.

The performers looked like ill-dressed scrawny young adults, male and female. All well shorter than the typical person of northern European background. They were riding equally scrawny looking ponies in an arena about the size of a hockey rink. The kids did stuff like ride standing on the pony as it galloped around the field, then would flip to be sideways on the horse, with the body of the pony completely blocking them from one side. They'd fire arrows at full gallop, hiting tiny targets as they would abruptly change direction.

That's when my understanding of Atilla the Hun and Ghenghis Khan went beyond what I'd read in books.

There was a medieval French saying to the effect of 'if they are not an expert rider by puberty, they can never be a knight'.

If there was a viable low cost superconductor that worked at temperatures up to 50 degrees Celcuis and atmospheric pressure, the implications would include:

- way less heat generated in electronics, so faster and more efficient CPUs, GPUs and memory.

- power transmission without loss. Very long range power transmission becomes viable and low cost (buried cables near roads?). For instance, solar energy transmitted in real time from where the sun shines to where it is dark or cloudy.

- a major obstacle to fusion power is removed as superconductors make it much easier, lighter and smaller to use magnetic fields to confine plasma

- medical imaging and scanning gets much cheaper as, for instance, MRI machines get smaller, lighter and simpler.

- mag lev trains could become the lowest cost way to travel by rail. Maybe even cars and trucks become maglev and roads are replaced by magnetic rail.

" Dr. Brook’s analysis found there to be a very small chance that the thylacine is still around today. For that possibility, Mr. Mooney said that even if Tasmanian tigers did persist past 1936, the likelihood of their still being around shrinks all the time. Someone should have found one by now, given the high levels of roadkill in Tasmania and the increasing use of trail cameras in more remote parts. Dr. Brook agrees that we’re unlikely to discover surviving thylacines. "

" With optimal prompting, ChatGPT can perform some tasks surprisingly well. But with sub-optimal prompting, the results can be useless.

Also, some Excel users are prone to sinking time into it trying to get it to perform tasks that are more appropriately handled by other software tools. As with Excel, knowing what ChatGPT should and should not be used for will not be immediately obvious to a novice.

...Most of the potential uses of the software have not been imagined, much less tried and tested.

I am just trying to encourage you to become an early adopter. If you are one of the first people in your organization, or one of the first people in your profession, to learn how to form prompts well and how to incorporate ChatGPT’s output into your work, then you will probably enjoy a productivity advantage for several years. If I am correct, then the laggards will lose out to the early adopters. You are better off eating than getting eaten.

What will reduce the advantage of early adopters will be the emergence of a training infrastructure around ChatGPT. That suggests that one can earn a nice living as part of that infrastructure. "

After one or two riffle shuffles, some cards will remain in their original sequence. Even after four or five shuffles – far more than most casinos typically use – the deck will retain some trace of order. But once you shuffle the deck seven times, the cards become truly mixed, at least as far as most statistical tests can prove. Beyond that point, further mixing will not do much. "It's just as close to random as can be," Diaconis says.

[...]

Markov chains have no "memory" of what came before. This is a pretty good model for shuffling cards, says Assaf. The result of the seventh shuffle depends only on the order of the cards after the sixth shuffle, not on how the deck was shuffled the five times prior to that.

[...]

the Markov chain describing riffle shuffles has a sharp transition from ordered to random after seven shuffles. This behaviour, known to mathematicians as a cut-off phenomenon, is a common feature of problems involving mixing. Think of stirring cream into coffee: as you stir, the cream forms thin white streaks in the black coffee before they suddenly, and irreversibly, become mixed.

Which is to say, that the radiation could be measured is different from saying that the radiation represented a significant health risk.

The payload:

" Based on the CNEOS catalog of bolide events, we identify the ∼0.45m meteor detected at 2014-01-08 17:05:34 UTC as originating from an unbound hyperbolic orbit with 99.999\% confidence. The U.S. Department of Defense has since verified that "the velocity estimate reported to NASA is sufficiently accurate to indicate an interstellar trajectory... Its high LSR speed implies a possible origin from the deep interior of a planetary system or a star in the thick disk of the Milky Way galaxy." "

" I still don’t think I fully understand why these miracle years keep showing up in the lives of great scientists, except that it has something to do with them being young, concentrating intensely on the right problems, and remaining open to fresh perspectives.

Given how many of the great scientific discoveries have come about during miracle years, we should do everything we can to help smart Twentysomethings have an annus mirabilis. We should free them from rote menial work, prevent them from being overexposed to the current paradigm, and give them the freedom to explore far-fetched ideas without arbitrary deadlines or time-draining obligations.

It’s depressing that I have just described the opposite of a modern PhD program. "

This is largely thanks to a remarkable set of fossils and deposits in North Dakota that record the actual impact.

[from the paper:] " Impact-triggered tsunami deposits have been reported in nearshore-marine and continental shelf deposits around the Gulf of Mexico and the Caribbean, < 1000 km from the Chicxulub crater, and evidence of seismically induced surges ~ 3000 km from the crater were recently documented at the Tanis (North Dakota, USA) KPg mass-death assemblage. Extreme, long-term global climatic shifts including a prolonged multi-year dark post-impact winter, resulting from infusion of CO2 and SO2 admixed with soot and atmospheric dust, are considered the primary agents of critical terrestrial and marine ecological collapse. [...] The Tanis Event-deposit preceded the iridium-rich dust-sized fallout and was emplaced exclusively within the period of coarse ejecta accretion, which began in the study region ~ 13 min after impact and lasted for ~ 1 to 2 hours. The massive water surge, possibly originating from the nearby WIS, entombed the remains of autochthonous freshwater fish, turtles, reptiles, dinosaurs, and plants, mixed with allochthonous marine organisms including fish, ammonites, dinoflagellates, foraminifera, and marine reptiles, all intimately associated with impact ejecta emplaced via primary deposition.

The sediment package is capped and temporally constrained by an iridium-rich clay layer (tonstein) that typifies the KPg boundary in the Western Interior. [...] Additional seasonally aligned insect activity at Tanis is represented through mayflies. The annual periodicity of synchronized adult mayfly emergence is constrained to a very short time span, and therefore is a reliable tool for temporal constraint. Body fossils of multiple adult mayflies occur as compression fossils in the fine-grained silt in upper Unit 2 and uppermost Unit 1 of the Event-deposit. Mayfly burrow casts, some of which preserve the remains of larval mayflies, have also been found excavated into the wood of large (~ 20–30 cm diameter) tree trunks and aligned in dense subparallel groupings that follow the grain of the wood (presumably following the path of least resistance). The burrows, preserved in full relief as matrix infillings, occur exclusively in wood that had previously died, i.e. exhibited no attached branches with leaves or other evidence that they were fresh at the time of burial. Extant mayflies exhibit highly constrained annual behaviour, beginning their life cycle during the Spring spawning period, at which time eggs are deposited in a freshwater environment. Larvae, living on the bottom or in U-shaped burrows excavated into soft substrate, mature over a period of months to years. The final adult moult and emergence occur en masse during a very short (< several week) time span that typically occurs in the latest Spring and Summer, between April and July 50–52 . Adults live subaerially only for a period of hours to days before dying in large groups. The adult mayfly body fossils at Tanis therefore indicate that the depositional event occurred during a short time span in late Spring or Summer, after the appearance-window for adult mayflies, and prior to a complete disintegration of their very delicate bodies.
