1/9 - “In the second wave we acquired much more evidence that schoolchildren are almost equally, if not more infected by SARS-CoV-2 than others.”

 2/9 - “The problem is not that schools are unsafe for children,” Mr. Boris Johnson said last week. “The problem is schools may nonetheless act as vectors for transmission, causing the virus to spread between households.”
3/9 - “An antibody survey conducted by researchers in Geneva in May and December, using thousands of random samples, found that children of age 6 to 18 were getting infected as often as young adults. The study has yet to be peer reviewed.”
4/9 - “One reason for this: The Swiss city’s schools have been open since the summer, while restrictions have been placed on adults, meaning schoolchildren played a bigger role in transmitting the virus during the autumn surge.”
5/9 - “In Austria, a nationwide survey by universities and medical institutes found that children under 10 showed a similar rate of infection to those between 11 and 14, and that the children in general were getting infected as often as teachers.”
6/9 - “Scientists also point to data from the U.K. which conducts a weekly random survey of the population. Just before the Christmas break, when schools were still open, the positivity rate among children was higher than in most adult groups, especially in those older than 11.”
7/9-“In Germany, researchers found that a majority of some 40 cases at a school in Hamburg in Sept were likely linked to a single person,which some scientists say highlights the risk of schools becoming #COVID19 clusters. Still, many policy makers in Europe say schools are safe.”
8/9 - “In France, which managed to curb infections while keeping schools open, PM Jean Castex ordered a nationwide 6 p.m. curfew but said it was a fundamental goal to keep schools open. FR is now imposing stricter rules for school canteens, and stepping up testing in schools.”
9/9 - “Austria, one of the first European countries to shut schools in November, plans to reopen them gradually from Jan. 25, but in staggered systems and with millions of test kits distributed to reduce the risk of infection.”

The Google Doc where the San Francisco school board did it's research for deciding which historical figures to cancel is public, and it's hilariously bad

The best part is the "Notes" tab, where someone lays out why the stated reasons are complete BS.

Case in point: "Lowell High School must be renamed because the namesake was a racist."

Notes: "Yeeeah, no, it wasn't named after that guy at all."

(they voted to rename anyway)


Another example: "Paul Revere led the Penobscot Expedition, which led to the colonization of the Penobscot."

Notes: "What? No. The Penobscot expedition was fought against the British, in Penobscot Bay. The natives weren't involved."

(voted to rename anyway)


"Dianne Feinstein was responsible for evicting an entire Filipino neighborhood!"

Notes: "That happened in 1977. She wasn't mayor until a year later."

(voted to rename anyway)


"Abraham Lincoln executed 38 Dakota Indians!"

Notes: "The Minnesota governor was going to execute *300*. Lincoln intervened when he had no obligation to, and saved the vast majority of them."

LIST OF QUESTIONS FOR MPS
From @ClareCraigPath and Dr Jonathan Engler:
.
1.Why are SARS-CoV-2 antibody levels flat or dropping across all age groups since May if the pandemic is still going?

2.What percentage of the population is assumed to have had prior immunity to SARS-CoV-2 in the SAGE forecasting models?

3.Why do 50% of household members not catch SARS-CoV-2 from infected persons with whom they live?

4.Why have Japan and South Korea not had any serious outbreak if the human species has no prior immunity to SARS-CoV-2?

5.What percentage of the population of the UK is assumed to be immune to COVID-19 (including prior immunity) as of this date?

Last month I presented seven sentences in seven different languages, all written in a form of the Chinese-character script. The challenge was to identify the languages and, if possible, provide a


Here again are those seven sentences:

1) 他的剑从船上掉到河里去
2) 於世𡗉番𧡊哭唭𢆥尼歲㐌外四𨑮
3) 入良沙寢矣見昆腳烏伊四是良羅
4) 佢而家喺邊喥呀
5) 夜久毛多都伊豆毛夜幣賀岐都麻碁微爾夜幣賀岐都久流曾能夜幣賀岐袁
6) 其劍自舟中墜於水
7) 今天愛晚特語兔吃二魚佛午飯

Six of those seven sentences are historically attested. One is not: I invented #7. I’m going to dive into an exploration of that seventh sentence in today’s thread.

Sentence #7 is an English-language sentence written sinographically — that is, using graphs that originate in the Chinese script. I didn’t do this for fun (even though it is fun), or as a proposal for a new way to write


I did it as a thought experiment. Why? Because thinking about how the modern Chinese script might be adapted to write modern English can give us valuable insights into historical instances of script borrowing, like those that took place centuries ago in Japan, Korea, and Vietnam.

Our preprint on the impact of reopening schools on reproduction number in England is now available online: https://t.co/CpfUGzAJ2S. With @Jarvis_Stats @amyg225 @kerrylmwong @KevinvZandvoort @sbfnk + John Edmunds. NOT YET PEER REVIEWED. 1/


We used contact survey data collected by CoMix (https://t.co/ezbCIOgRa1) to quantify differences in contact patterns during November (Schools open) and January (Schools closed) 'Lockdown periods'. NOT YET PEER REVIEWED 2/

We combined this analysis with estimates of susceptibility and infectiousness of children relative to adults from literature. We also inferred relative susceptibility by fitting R estimates from CoMix to EpiForecasts estimates(https://t.co/6lUM2wK0bn). NOT YET PEER REVIEWED 3/


We estimated that reopening all schools would increase R by between 20% to 90% whereas reopening primary or secondary schools alone would increase R by 10% to 40%, depending on the infectiousness/susceptibility profile we used. NOT YET PEER REVIEWED 4/


Assuming a current R of 0.8 (in line with Govt. estimates: https://t.co/ZZhCe79zC4). Reopening all schools would increase R to between 1.0 and 1.5 and reopening either primary or secondary schools would increase R to between 0.9 and 1.2. NOT YET PEER REVIEWED 5/

My thoughts about Covid in schools-
Our studies are crap. We haven't put appropriate resources into studying this. Merging "in-person school" v "remote school" across the country makes little sense since there's so much heterogeneity in what "in-person school" looks like. 🧵

A teacher in Louisiana in an area with high rates of covid & in-person school, has a class with just 2 students in it. The entire school has 37 students and 12 staff, in a building that can hold hundreds.
Should this school's data be merged with a school that's fully open?

How would merging such disparate data, and everything in-between impact our understanding of Covid in schools? What about when we compare it to the rates in children who are in virtual school?

Things often not considered that should be... Are kids in pods? Are kids doing virtual school in community centers/ churches/ other group settings? Are youth sports or other extracurricular school activities (music, etc) happening in-person. Heterogeneity exist in this group too.

What's asymptomatic testing of children in the community like? We know that children are under-tested, how can we say something is safe if we are NOT TESTING children at the same rate as the rest of the population. We can't embrace the "don't ask (test) don't tell" apprach here.

The Haas / Force India argument is fascinating, and the decision of the stewards may still have consequences. The first key finding is that the stewards ruled Racing Point Force India to be a valid constructor. That means that it builds its own cars.

Haas had argued that the cars had been designed by Force India, but as Haas knows only too well, "outsourcing" is legal. The stewards decided that "there is no regulatory support for the argument that Outsourcing of Listed Parts cannot come from a former or excluded team."

In determining this, the stewards also came to the following conclusion: "In relation to the submission by the Racing Point Force India F1 Team that it is not a new team, the Stewards decide that the Racing Point Force India F1 Team is indeed a new team."

This will have a big knock on effect for Haas in its continued arguments over the rights of RPFI as relates to its eligibility and rights under the complex payments structure. Haas has argued all along that RPFI should be treated as a new team and tread the same path that it did.

TLDR? Haas lost the fight but may have won the war. In having its argument that Racing Point hadn't designed their own car thrown out, they gained clarification that RPFI was a new team.

1/ So here is a thread on how I turned $32,000 into $1.2m and back to pretty much zero (once taxes are paid).

Just note, I am not bitter or salty in any way at all, the last 2 years have been an amazing ride - travelled the world, been wealthy, been poor.

2/ Dec '16, my advertising agency folded, I had a little bit of money left and I put $32k into Bitcoin and Ether. As it started to go up I diversified into everything, Monero, Dash, this that, any crap - even Ripplecoin. Everything just kept going up.

3/ By March I think I had around $300k and $500k by the summer. I used to take 25% out but towards the end of the summer I got greedy and put it all back in and by December it was $1.2m.

4/ Thinking I was an absolute genius I decided to start a bunch of businesses. As silly as it sounds I had this goal of making $5m as I wanted to buy Bedford Town Football Club and get them in the league, and as Crypto was going up forever I needed 6 months.

5/ So:
- Trading (income 1)
- Podcast (income 2)
- Mining (income 3)
- Mining pool (income 4)
- Consulting (income 5)

Yes - all of the above as a one-man army :)

🎉🎉 PHP 7.3 is here!

Here are the things I'm excited about.

🚂 Trailing commas in function/method calls!

This will certainly be a required styling choice for me. Same delightful benefits of trailing comma in multi-line PHP arrays, and JavaScript objects.


🧵 Less disgusting heredoc syntax!

Inlining heredoc strings in any way right now is grrrosssss. Now we get sensible capabilities. Everything that was wrong with it is now fixed!

(Ignore the bad syntax highlighting)


☠️ Finally, not-so-silent json_decode error detection!

This really sucked before, now it just sucks a bit less (who wants to pass a 4th param and pass 2 default params first? (helper function anybody?)


📜 Not horrible functions for getting the first and last item (or key) from an array!

Before you either strung a bunch of functions together or messed with internal array pointers. This is a much-needed improvement.

👇Thread.

Published a new essay: The red flags and magic numbers that investors look for in your startup’s metrics – 80 slide deck included!


This was a deck that I created on my (longish) interview process with @a16z. It was a long path, starting with meeting folks at the firm 10 years ago. But the purpose of the deck was to explain how I would use my superpower in an investing context

Here's what I explain in the deck. As investors (whether angel or VC) we're often confronted with an up-and-to-the-right graph. Is it going to go up? Or down?


One solution to forecast these growth curves is the Growth Accounting Framework, where you add up New+Reactivated and subtract churned users. In each time period that gives you the difference in monthly actives.


The problem with this is that it's a lagging metric, not a leading one. We need to go one level deeper and look at the underlying loops that drive these numbers, to understand the quality.

How to create a freelancing website that makes money.

Everything I've learned.

A thread.

As a freelancer,

Your website is everything.

First, prioritise its existence.

Second, prioritise its improvement.

The technology you use is irrelevant.

- WordPress
- Notion
- Carrd
- Wix

It doesn't matter which you choose,

What matters is you have a website.

Pick a platform that you're comfortable with.

If you can:

- Capture leads
- Add content easily
- Have a clear design

You're good.

If your website doesn't get leads,

It's not working.

Don't rest on a website that doesn't work for you.

Improve it until it does.
