A few weeks ago @ClareCraigPath, @RealJoelSmalley and I wrote a short piece on endemic Covid, and what it might look like.

It seems particularly relevant to current

 Consider the possibility that all our naso-pharynxes together make up a single ecosystem, in which only one predator can be completely dominant.

We are not saying that this has definitely happened with Covid - but it would explain the disappearance of flu this year.
Every winter, we see "excess deaths" in the sense that more (mainly elderly) people die in the winter than in the summer.

This is a worldwide phenomenon.
It is now thought that all or nearly all of the extra deaths in Winter are due to infection with winter respiratory viruses, mainly influenza:

https://t.co/xOHDcSRgGB
However, we do not - and never have - extensively tested for the presence of such viruses in the critically ill elderly population, so we really have no idea how frequently infection is present, or in fact what its contribution to death is.
In 2017, researchers at 2 morgues in Spain swab-tested a series of recently deceased elderly individuals and found respiratory viruses in 47% of them. In only 15% of these had a diagnosis been made prior to death.

https://t.co/PBUnIfLtaf
The death certificates for all these individuals featured the usual wide range of pathologies that would be expected in this age group, but viruses were detected (post-mortem) across all categories of causes of death.
For this cohort - presumably representative of similar cohorts of subjects across Europe - what would the mortality picture have looked like had we applied a policy of recording the detected respiratory virus as the cause of death, irrespective of other pathologies?
That is, in effect, what we might be doing now, to some extent - Covid taking the place of other viruses (particularly influenza).

In other words, might some of the Covid deaths we are now seeing be those that would have sadly died in a normal winter anyway?
As is usually the case, the picture is more complex and there are probably a number of other factors contributing to the current mortality picture.
Firstly, there will of course be some additional "pure Covid" deaths as the virus moves into its endemic rather than pandemic stage.

This was seen in the year following the Swine flu pandemic:

https://t.co/uIB5lF7CKU
Secondly, there is increasing evidence of deaths being caused by nearly a year of restricted access to healthcare.

In fact, given the nation's state of health and presence of multiple diseases, it would be more surprising if there was no such effect.
That attendances at A&E departments making up the Syndromic Surveillance System (currently covering 82 hospitals in England) are running below the same period last year is consistent with this:
Ambulance calls for cardiac/respiratory arrest calls are high, yet calls for chest pain appear to be lower than average.

This is worryingly consistent with a picture of reluctance to seek help in time.
This would be highly unlikely to result in no excess deaths.

The numbers involved are not small, the arrest calls appear to be ~50-75 more than expected (daily), but chest pain calls ~250 per day fewer than expected.
Surprisingly, attendances for acute respiratory infections are well below average for the entire Autumn and Winter so far; although rising recently they are still below average.

This is consistent with the point made above - ie could Covid be replacing flu this year?
Some have previously claimed that this category does not include Covid, but the notes in the report seem quite clear that it does.
Finally, it must be acknowledged that the emergence of Covid is currently causing significant strain on our NHS, although it is worthwhile acknowledging that several reasons must contribute to this.
Firstly, it appears that treating Covid patients is more complex and onerous than treating those who would previously have been patients with a variety of other
- mainly undiagnosed - respiratory viruses.
Secondly, the reduction in beds available for a growing and ageing population is a major problem; they fell from 240,000 in 2000 to under 165,000 in 2019.

The figure fell by a further 10,000 beds to allow for social distancing between patients in hospital.
The need to segregate suspected Covid from confirmed Covid and non-Covid patients has a detrimental effect of bed management, as does the need for smaller bay sizes to accommodate distancing.

A&E departments can easily become clogged up by delays in finding beds for patients.
In some hospitals patients are not being discharged until their Covid test returns as negative.

Clearly returning patients to care homes during the window of infectivity would be a bad idea.

Beyond that this policy is surely inadvisable.
It should be recalled that some patients continue to test PCR positive for weeks or even months after infection, as experienced by the unfortunate British students stuck in Italy last summer:

https://t.co/qaIsjDD5Mm
PCR testing has led to a staffing crisis, as asymptomatic staff - even those who must be immune through known prior exposure - are made to self-isolate for two weeks.

50,000 NHS staff are absent for Covid reasons, out of 100,000 total absences.

https://t.co/qgpc00Otie
Finally, it should be acknowledged that staff are having to work in PPE and change it frequently, adding a significant additional burden to an already heavy workload.

1/ Something strange is happening with people’s sex lives. 20-somethings are having sex later and less frequently than previous generations. I spent several months digging into this for @theatlantic. https://t.co/5ehzmWY9wi


2/ This phenomenon—I’m calling it a Sex Recession—really surprised me. It seemed improbable in the age of Tinder, digital porn, and attitudes that are generally permissive and sex-positive.

3/ What’s happening isn’t exclusively American: Similar trends are being observed in other countries, including Japan, Australia, the U.K., Finland, and the Netherlands.


4/ One cause is obvious: Adults under 35 are less likely to be living with a partner than in recent decades, and more likely to be living with their parents—which, it’s safe to say, isn’t great for one’s sex life.

5/ But I also found other explanations, each with profound implications. The first, unsurprisingly, has to do with internet enticements. Netflix and other online entertainment may be substituting for sex.

Offered a guy a ride from Yaba to Obalende this morning. Just as we're approaching Alagomeji, uncle asked me if he can drive. Said he's not comfortable being driven by a woman. I parked and told him to come and take the wheel. Once he got down, I just zoomed off. Arrant nonsense

Funny thing is the guy is quite young. He can't be more than 25. How can someone that young have this sort of mentality?

I actually did not think that the guy could have wanted to get away with my car at the time. Now that I think of it though, that's a big possibility. We need to be careful out there. These thieves now have different ways of operating

Capitalism demolishes society and, with it, itself.

A thread.

1/

Prior to capitalism, there were plenty of elite-centric, exploitive systems in place. European and Japanese feudalism. Roman mass slavery. The corvee labor of the ancient hydraulic state. Etc.

2/

But as exploitive and repressive as these systems were, they still retained some sense of mutual obligation among classes. Elites depend on the masses to survive and thrive. You can only exploit them up to a certain point, beyond which you threaten your own labor supply.

3/

Consider this quote from Kenneth Jupp on European feudalism. Feudalism entailed *mutual obligations* between rich and poor.

4/


These obligations were not equal, uniform, or always universally respected. But they were at least *there.* In return for labor and agricultural surplus, a feudal lord was obligated to protect his villeins, provide them justice, and respect their usufruct land rights.

@thetwinkwolff @x_karran_x @Sunil9130 When the Europeans or South Americans were getting quality practice and tourneys week in week out at reasonable costs, our kids were playing on dung courts or learning outdated serve and volley on grass. Appreciate the fact that the last 10 years have been a hell lot better than

I was in love with Steffi and Pete a lot before I fell for Sachin. And while I would love every toddler in my family to play sports professionally, I won't encourage them to pursue my favourite sport.

@thetwinkwolff @x_karran_x @Sunil9130 @siyer30 @SportaSmile @Cric_Writer @RomilShukla @amanthejourno It will be career suicide. In other sports, I can actually plan for my ward to be the next Lin Dan or the next Tiger Woods or the next Schumacher even from a base in India. With tennis, in 2020 I can't do that realistically. Just doesn't adds up. Even for total freaks of nature.

I'm going to do two history threads on Ethiopia, one on its ancient history, one on its modern story (1800 to today). 🇪🇹

I'll begin with the ancient history ... and it goes way back. Because modern humans - and before that, the ancestors of humans - almost certainly originated in Ethiopia. 🇪🇹 (sub-thread):


The first likely historical reference to Ethiopia is ancient Egyptian records of trade expeditions to the "Land of Punt" in search of gold, ebony, ivory, incense, and wild animals, starting in c 2500 BC 🇪🇹


Ethiopians themselves believe that the Queen of Sheba, who visited Israel's King Solomon in the Bible (c 950 BC), came from Ethiopia (not Yemen, as others believe). Here she is meeting Solomon in a stain-glassed window in Addis Ababa's Holy Trinity Church. 🇪🇹


References to the Queen of Sheba are everywhere in Ethiopia. The national airline's frequent flier miles are even called "ShebaMiles". 🇪🇹

1/OK, I should really write another thread about university-centric regional development, because I think people often make some (very understandable) mistakes when thinking about this issue.

2/The biggest myth, I think, is that universities help regions by educating locals as undergraduates.

Skeptics of universities say: "But most of the people who graduate end up leaving."

3/In fact, most of what a university does for a regional economy is NOT about educating local kids.

Educating local kids is good for the nation, but doesn't help a region much.

The way a university helps a region is through

4/Undergraduates usually leave town after graduation.

But university RESEARCH pulls in OTHER smart people from other regions, and they stay there.

Here's a paper showing that this is the main way universities increase a region's human capital:

5/Research also pulls in business investment.

Companies want to partner with university labs, so they can commercialize the technologies the labs produce. So they invest in the labs, and sometimes they even put their offices in the town.

The first area to focus on is diversity. This has become a dogma in the tech world, and despite the fact that tech is one of the most meritocratic industries in the world, there are constant efforts to promote diversity at the expense of fairness, merit and competency. Examples:

USC's Interactive Media & Games Division cancels all-star panel that included top-tier game developers who were invited to share their experiences with students. Why? Because there were no women on the

ElectronConf is a conf which chooses presenters based on blind auditions; the identity, gender, and race of the speaker is not known to the selection team. The results of that merit-based approach was an all-male panel. So they cancelled the conference.

Apple's head of diversity (a black woman) got in trouble for promoting a vision of diversity that is at odds with contemporary progressive dogma. (She left the company shortly after this

Also in the name of diversity, there is unabashed discrimination against men (especially white men) in tech, in both hiring policies and in other arenas. One such example is this, a developer workshop that specifically excluded men: https://t.co/N0SkH4hR35

Chennimalai Murugan Kovil
#Erode
#TamilNaduTemples 🚩

Chennimalai Murugan Temple is located  near Perunthurai in Erode District. Murugan is worshipped here as Dandayudapani. Temple is situated on the banks of Noyyal river also called Kanchima Nadhi. Temple is situated in a hill


Sthala Puranam says that, there lived a Landlord who had many cows in his farm. One among them was a Black Cow, which didn't give milk. Land lord observed that evening time, when all the cows came back after grazing, this cow used to go to a particular spot and gave all  the milk


by itself. He decided to dig the spot where the cow gave its milk

On digging a beautiful Vigraham of Murugan was found, but lower portion was very rough. So he called a great sculptor to soften it. Everyone was shocked to see that on the first chisel the vigraham bleeded.


Land lord realized that Murugan wanted the Vigraham the way it was.

Thus Prathishta was done on Chennimalai hill. It is believed that Sivalaya Chola got relieved from his Brahmahatti Dosha here. Kanda Shasti Kavacham was first offered here.

🕵️‍♂️ How Google's PageRank algorithm works

The PageRank algorithm gives each page a rating of its
importance, which is a recursively defined measure of importance, based on if important pages link to it.
It's recursive because the importance of a page refers back to the importance of other pages that link to it

Here's how it works in practice:
1⃣ We start with some pages and crawl them for links


2⃣ Each page has 1/N points (where N as the total number of pages)


3⃣ Add points to each page for the amount of links to it, divided by the number
of links emanating from the sources of these links
