THE FUTURE OF NEWSLETTERS
(and announcing my new newsletter πŸŽ‰)

Too much noise, too little content we actually use.

Take your favorite newsletter. Can you remember the contents of the edition-before-the-last-one?

Me neither. But I have a solution

(thread, 1/N)
2/ Today, I launch the RoamLetter.

A newsletter whose content directly integrates into your note-taking system.

A newsletter whose editions AUTOMATICALLY link with each other *and with your notes* πŸ‘

A newsletter with built-in spaced repetition.

A timeless newsletter.
3/ If you are a Roam user, you'll enjoy how the topics of one edition of my newsletter automatically link with your body of knowledge, and the other way around.

If you are not a Roam user, no worries. You can still use all the other features of my newsletter (pics below)
4/ I write personally all the content of the newsletter.

So, you'll read what I'm known for.
Timeless content, comments on the principles ruling this world, complex systems, emergent behaviors, adaptive management, and much more.

Get a look inside: luca-dellanna.com/roamletter
5/ Every week, I will publish essays of mine, most of them exclusive to the newsletter, or present my comments on the essays of others (links to them + one-paragraph take-away of one key idea + my thoughts expanding and building upon them).

All categorized, for easier reference. Image
6/ Here is an example of what I mean by "building upon".

If you are familiar with my writing, you'll know that I don't regurgitate the works of others, but take away some principles and apply them to different contexts – or make novel hypotheses. Image
7/ Every week, also a section on the best quotes and thoughts I came across. Again, with my comments. Image
8/ Finally, a section on recent news – but never caring about the urgent, only about the important.

The aim is to highlight phenomena or principles that will still be relevant in a few decades. Image
9/ Moreover, the newsletter comes with spaced repetition. Every 3 months I will send you a recap of the most important concepts I've talked about during the last few editions.

And once a year, a mega-recap.
10/ You can subscribe here: luca-dellanna.com/roamletter

The first edition gets published this Saturday!
11/ Yes! Subscribers can ask questions, and I’ll answer them at the bottom of the following edition.

(Assuming the question is relevant and not confidential, trivial, or offensive)
12/ Also, there’s a time-limited pre-launch offer (Luca-Dellanna.com/RoamLetter)
13/ A few readers asked, "do I need Roam?"

No! There is an email-only version of the newsletter: luca-dellanna.com/premiumletter (which is distinct from my free "updates & occasional essay" newsletter)

ROAM BOOKS ARE THE FUTURE OF EBOOKS
(thread)

3 days ago, I published the first @RoamResearch book ever (gum.co/ergodicity).

Once you try this format, you won't come back.

Here are 5 of its features (thread, 1/6)
2/ The first feature of Roam books, or rBooks for short, is that they allow for non-linear exploration.

Their pages are like Wikipedia pages – they contain links for optional deeper exploration.

Moreover, at the bottom of each page, there is an automatic list of references.
3/ Roam books are still books – they still have a table of content that guides you through your journey of discovery.

However, you can stray off the path or take shortcuts as you please.

MASKS WORK EVEN IF THE VIRUS IS SMALLER THAN THE HOLES IN THE FABRIC

As a first effect, the virus bounces on the fibers. That's enough to decrease the distance at which it "jumps out". It might even get some of the particles to stuck to the fibers.

(thread, 1/N)
2/ Second, N95 masks also have electrostatic charges that capture particles even if they are smaller than the holes in the fabric.
3/ Third, masks would work even if the virus passed fully through.

They reduce the distance at which it travels after, say, a sneeze. It's as if they introduced additional distance between people.

Moreover, they work both on the way out and on the way in.

More than 3 millions of Italians violated home quarantine (of those whose close contact tested positive or were waiting for test results),

according to the Italian Scientific Committee advising the government on COVID response.

(source: open.online/2020/11/01/tra…)
Part of the problem is the slow testing.

6 million Italians should be in home quarantine, only a fraction of them because they tested positive. Most of them are there because tests are few and slow.
Another part of the problem is that enforcing the quarantine & working through the tests backlog is cheaper, easier, and more effective when there are few cases than when there are a lot,

But one would also need the will, capability, and wisdom to do so when it seems less urgent

A REVIEW OF BAD ARGUMENTS AGAINST FACE MASKS

1/ They don't fully protect you from virus in the air.

Yes, but their point is to prevent as much virus as possible from getting in the air in the first place.

(thread)
2/ There is this Randomized Control Trial I see posted on Twitter which allegedly shows that face masks do not work.

That trial shows that face masks do not protect doctors from patients *that do not wear face masks*.

Such studies do not demonstrate that face masks don't work.
3/ Paradoxically, the more you believe that someone wearing face masks is only partially protected, the more you should want everyone to wear them, so that there is less virus in the air.

That's how real herd immunity works.

So, earlier today I posted a wrong tweet, which I then deleted. Thankfully, it only stayed on for a few minutes.

But I think it's important that I explain what I got wrong and why, for some could benefit too.

(thread)
2/ I was commenting on this chart.

I correctly pointed out that the increase is relative. For example, it doesn't mean that more young people died than old.

However, I also wrongly added that the chart showed the increase in COVID risk for the young.

3/ I didn't consider that young adults tend to die of causes such as cancer that got impacted negatively by the lockdown (no cures)

The chart being about all-mortality, & the absolute number of young adults deaths being fairly low, the *direct* contribution of COVID might be low

In yesterday's tweet, I was critical of scientific institutions endorsing specific parties.

Here is an example of why.

There is no such thing as "the scientific party" or "the anti-scientific one" – not if by science we intend real science, rather than a politicized consensus.
IMHO there's too much focus on who governs the political structure and too little attention to whether:
- The structure is good
- It provides good incentives
- It filters bad members
- The downside of bad decisions is capped
- It provides longevity to the common good or to itself
(I don't live in the US and this was not intended to be a reflection on the US; I merely stumbled on the quoted thread and it made me think. Many other countries will find that, if they remove the words and look at the actions, "scientific parties" aren't that scientific at all.)
