> This doesn't include back links or transclusion, but I don't think those are make or break features either?

I thought this at first as well, but automatic backlinks make a bigger difference than you may guess. It basically turns each document into two things: 1. the document itself, 2. an automatic query of all references to this document that renders automatically as soon as the document is opened. Just like you can have a document with content but isn't referenced anywhere, you can also have a document with no content whose purpose is only to be the place where everything is linked back to, and persistent filtering per document means that you can make it behave exactly how you want. There is no difference between the concept of a saved search and a document, they have been unified.

The biggest value proposition to me is that you maintain each document by itself, only changing things in one place, and other documents/views automatically reflect that. Automatic backlinks with persistent per-document backlink filtering is one way Roam enables this pseudo-DRY thing where you only edit things in one place.

The other big thing it does to enable you to avoid repeating yourself is document embedding: where one line of a document or whole sub-document is referenced and looks like it's embedded in the middle of some other document. Interacting with an embedded document works the same as editing any section (you can still tell it's linked, there are read only modes etc) and the edits actually go through into the original document. Combined with fine-grained sub-document references (e.g. a paragraph or a single todo checkbox) this allows you to create things like temporary daily task lists where when you check off items they actually get marked completed in their related project where you created them, and you don't have to manually synchronize any edits. It's like you get to have your cake and eat it too. For example: do you want to organize your tasks along with the project they're related to, or do you want to organize them in the order you want to do them today? YES.

Not having to repeat myself is by far the best feature for me, and back-references combined with sub-document embedding both enable that to a very large degree. I despise having to maintain the same collection or list in multiple places, or the friction of renaming a document because now you have to fix all the references to it, or even keeping the name of a file in sync with the document header. These are things that I find pure files on disk grates on me enough to abandon the affair.
Indeed, it is not.

Your doctor is talking nonsense. There's mountains of studies on things that can't be patented. We don't have studies on much of anything wrt COVID-19. And most of the energy has gone to hydroxychloroquine whose patent expired long ago.
hasn't it been shown that vitamin-D deficiency has been shown as an aggravating factor in case mortality with covid? It's not a big extrapolation then to suggest places with warm sunshine would tend to have better outcomes.
We focus fairly heavily on engineering, particularly on QA. My co-founder Kerry Boyte ran QA at Symantec, eToys, BBC, and a few other well known companies. She actually built BBC's digital TV testing lab herself. Ran testing for the MS Exchange version of Norton back in the 90s. And ran the web QA team at eToys before the suits messed things up there.

I'm a dev (ceo these days) and I wrote the first version of Wordfence. Also worked at many big and small companies in South Africa, London and USA. We're US based now. And so we're both engineering focused, and our process is to only ship rock solid code via excellent QA.

Funny thing. Finding vulnerabilities is actually just QA. And a vuln is just a celebrity bug. So this culture really helps foster great security research too.

Another big area we invest in is customer service. Our CS team does a great job and we also focus substantial energy on community support in free forums, which really helps foster goodwill from the community and build a relationship with folks who use our free product, many of whom become paying customers.

I started my career in ops in the 90s before moving to dev and am passionate about high performance (as you can tell from fastorslow) - and so we spend a lot of energy and budget on solid operations to support our products.

Kerry is kind of a math guru and is our COO and CFO these days. So we run a tight ship in terms of financials, which is pretty much why we're still around. Cashflow plan updated daily. Awesome projections. Awesome granularity. Sorry if I'm over-sharing, but I love entrepreneurship and perhaps this will give other folks starting out some insight.

We have around 3 to 5 million free customers. Can't share how many paying, but it's a lot.

I haven't coded for some time now. In 2015 I completely handed off coding on Wordfence to a brilliant developer named Matt who is still with us. I've moved my focus 100% to leadership, strategy and somewhat of a CTO role, but I share that with the strong tech leads in our engineering team.

Hope that helps. We're a private company, so I couldn't just dump our internal data, but I hope that gives you some flavor of who we are, our focus, team distribution and culture.

Regards,

Mark.
> Does such a thing exist at higher dimensions?

Yes, everything in your first paragraph extends to any number of dimensions (replacing "quaternion" with "rotor").

> I vaguely recall something about having complex numbers for 2D rotation, quaternions for 3D rotation, and octonions for (I'm guessing) 4D rotation

Bivectors and rotors faithfully represent rotations in any number of dimensions. The octonion product can't, because as you said, it's not associative, but rotations obviously have to compose associatively.
Well, we get 3D scenes/projections on a 2D screen by being in a 3D world/context and looking at a 2D screen. With that I mean to say that I think (not sure) a 2D image of a 3D projection can only feel 3D if you're in a 3D world.

This also means such a thing should be possible for living in a 2D space and then projecting a 2D world on a 1D screen.

If you're going to play with 3D projections of 4D objects, then in order for it to really feel 4D we need to live in a 4D world. In that sense, this is quite similar to living in a 2D world while seeing a 3D projection. That's way more trippy.

To recap:

Feel 3D: 3D context -> 3D projection -> 2D screen

Feel 2D: 2D context -> 2D projection -> 1D screen

Feel 4D: 4D context -> 4D projection -> 3D screen

What we can do for 4D: 3D context -> 4D projection -> 3D screen

Compare issue with 3D: 2D context -> 3D projection -> 2D screen

I hope this makes sense (and I hope I have it right).

I'm not sure productivity is measured correctly.

In general it's measured something like increase in $/employee.

But let's say you're a commercial printer. The industry is moving to new printers that print double the amount, per employee hour.

If prices stayed the same, you'd see double productivity.

But because every company has the new, fastest machine , prices greatly reduce, and stop reflecting the fact that a single employee can now do 2x the work.

Yea, I left Slashdot after The Great Redesign, and other websites too for similar reasons. It seems to be this inevitable milestone in any website's (or, generally, software's) life:

- V1: Focused, works, fast, lacks some features, but good enough to grow

- V1.1: More features, still performs well, exponential community growth

- V1.2: Adds chat, messages, social, loses focus, performance starts to suffer, linear or slowing growth

- V1.3: Start loading up with ads, things are getting worse, usage plateaus or teeters

[EMERGENCY! HIRE THE DESIGNERS!]

- V2.0: Huge, unnecessary re-design [1] without community input. Most features gone. More ads. Community craters. This is the Fark.com "You'll get over it" phase.

- V2.1: Saturated with ads, founders have moved on, site is on autopilot, a shell of what it used to be.

I hesitate to take any medical advice from the internet, but from what I can tell searching around a bit, the general consensus is that somewhere between 10 to 30 minutes of direct sunlight a day is more than sufficient (depending on how high the sun gets in the sky at your latitude and time of year..)

Some companies can use this as a proxy to protect themself against variation of a product they need. For example an airline can use this to protect itself against price variation of kerosene once they have sold a ticket. As kerosene is not directly available on commodity market they use this future because their price are strongly correlated to kerosene price.

That is only true if you also have a potassium deficiency and low K2-MK7. That's why, when testing D levels, it's also important to test Ca levels. And even then, you have to be taking very high levels of D. More on the order of 50K UI a day for a long time.
I'd think it's the second lesson that will be learned.

Musk has been on the verge of failure for years, and cracks are showing now more than ever before.

I'd hate for everyone to stop dreaming for tomorrow just because one guy couldn't pull off everything imaginable.

For all the good things Musk does, he also does a lot of bad things. Including but not limited to dreaming up absurd fantasies to "reinvent" industries he has literally zero experience in (aviation comes to mind, drilling tunnels, underwater rescue, etc) - and everyone fixates on that imaginary solution because he said it.

Not to mention taking credit for all the hard work the actual aerospace, mechanical and other engineers are doing under Musk. Very seldom do you hear Musk talk about how incredible the team is and how lucky he is to have them working on these problems. No, instead he has the gall to call himself Lead Designer this, or Chief Architect that. We all know he's not sitting down and crunching math to design rockets and cars and more.

Look at Hyperloop. People are still wasting money, energy and resources on it, regardless that what we have in testing today are just Maglev trains in tubes... a far cry from what Musk originally dreamt up. Nevermind how impractical or prohibitively expensive and uneconomical it would be to build trains across the US, oceans, across the world all connected.

People want to dream. Fine. But trusting all of the future to just one guy... I'm not so sure.

Yeah I actually wrote a prototype in Django and flask and just felt like I was reinventing the wheel too much with flask. e.g. marshmellow = serializer from DRF, sqlalchemy = django orm, etc. I wrote password hashing with bcrypt for user logins and then realized I should salt the passwords and just went back to django since it already has stuff for everything I was doing.

I actually don't mind the heavy framework thing because .net core mvc is the same deal. The developer experience in python was just way worse for me. Autogenerating swagger docs didn't seem possible without manually adding annotations to all my code (for flask at least), the battle-tested python libraries for web dev aren't async, mypy is obviously way worse than an actual type system, model validation (the thing forms/serializers handle) was more tedious, vscode was worse than visuals tudio.
I had no idea Sam Harris would be described as panpsychist. Interesting.
I don't consider it acceptable, but the number of people that would die if we literally just shut everything off (including "essential" services and utilities) is unacceptable. "The economy" as it exists today simply leaves too many people behind. When 8 billionaires have as much wealth as half the world, and when wealth is essentially freedom, that's what's unacceptable.

There is strong evidence that Vitamin D does nothing. Large scale studies of vitamin D supplements show no benefit.

The article above argues that it is actually sun exposure that brings health benefits, and that vitamin D is just a byproduct. This makes sense. If vitamin D levels are strongly correlated with good health, it doesn't mean that it causes it. There might be some third factor.

Realistically it's hard to beat IRC for low barrier to entry. Most major networks have web clients now, you pick a handle, type a hashtag, and you are in. The signup process for Discord makes me roll my eyes every time I have to use it. Also, the textual nature of the IRC interface and lack of Fisher-Price widgets and visuals to entertain the short attention span millennial makes for a more pleasant conversational experience.

That's where I started. It evolved into a simple CGI program that runs on localhost. That lets me view the markdown files in the browser. When I want to edit/create files, they open in a text editor.

Something that's different is that everything is stored in the tickets database of a Fossil repo (works with the default tickets database of any Fossil repo). That gives me for free (a) a full sqlite database for things like tag querying, and (b) version control and syncing.

Essentially, one of the theories is that severely low Vitamin D can cause a hypercoagulable state and also increase the risk of the “cytokine storm” often observed in Covid-19 patients.

From what I understand, the idea of "empty" no longer makes sense at that level. All you have are fields. There, everything is made out of fields and fields are everywhere. There is therefore no "empty" really anywhere, including inside yourself.

I just recently noticed this too. I have a bit of ADHD and I've found it helps me follow meeting discussions and such. Can't quite explain it because being tired should make focusing harder (and true, I'm probably a slightly less effective coder than normal right after a run, just because of tiredness). But for whatever reason I've noticed it's much easier to follow other people's lines of thought and catch the important details after a good workout.

Edit: upon further reflection, I think the big difference is it's a few-hour boost in self confidence. So it's much easier to follow conversations and ask probing questions, rather than being afraid to ask things for fear of looking foolish.
The key is when California first acted, I think, rather then when it started rolling back.
America's Meat Shortage
You wrote,

> California recognizes that economic restrictions are causing severe harm and began rolling them back today

But the OP wrote,

> Hopefully states like California that are following more conservative, evidence-based approaches to relaxing restrictions, will relieve some of the tension.

You are both correct: California is rolling back economic restrictions, but they are following a conservative, evidence-based approach to relaxing them. The OP's basic premise, however, is not at all false, and I sincerely hope you don't have the impression that the state is just throwing a switch and going back to "normal." It's not.

Or I should say, we're not. I don't know where you're located, but I'm in California -- the Bay Area, specifically. We don't even have official guidance on how restaurants are going to re-open yet, an the California Restaurant Association -- the business group that represents restaurants, and clearly has an economic motivation to get back to business -- has actively lobbied for the re-opening of their member businesses to happen slowly and very carefully.

I would like nothing more than to be able to start going back to my favorite restaurants and bars. But the reality is that for the last month, the daily number of new Covid-19 cases and of deaths hasn't been materially dropping in the US in the way it has in countries like the UK, Italy, and Germany, which strongly suggests that our collective behavior throughout April remained too relaxed in most states. The paradox of this pandemic is that the looser the restrictions we place on ourselves are, the more economic damage we're likely to face over the long term, not less, because we'll start cycling through repeated outbreaks, being forced to close businesses, districts, and even regions ad hoc, and running a much greater risk of overwhelming hospitals with bursts of new cases virtually all at once in stricken locales.
I visited Auroville in 2008, stayed two weeks, and found it an odd place indeed. Tourists could read about the huge expansion plans for the site which were set down back in the 1960s and 1970s, but all that growth seems to have stalled many years ago already. There was definitely a feeling of decay around the place, like an old socialist-era concrete monument that was supposed to represent the future but is now a sad cracked and stained relic.

Many of the younger people I met were only living in Auroville because they were born there, and they had little to no interest in spirituality, the Mother, Sri Aurobindo, etc.

Yeah I've heard that before, but from my (admittedly brief) time it seemed like you could just use the utilities you want and ignore the stuff that forces you into a CMS'y box. Feels like if you really wanted to you could just use a form/serializer to validate input data and to return a domain object, pass the domain object to a service layer, and then use the django orm (or honestly anything if you really want to stray from the django way), to handle database interactions. I understand flask might be nicer because you get to feel like you dont have a bunch of wasted code bloat in your deployable, but there are some pluggable systems that come with django that are nice (user system, pluggable authn/authz, caching framework, etc.) I didn't really mind the bloat because a lean deployable isn't that important to me and it all felt sluggish to me compared to .net core anyway.
While I suspect anyone reading this is going to detect at least a small hint of sarcasm, its true. Minimize distractions like this and unsurprisingly, productivity goes up.

My biggest one, to add, is having set time for handling administrative tasks, like Email etc. If you can (and I realize all people have caveats), just set a block of time in the morning and in the afternoon to answer email, and otherwise ignore it unless its been flagged a certain way.

This is what I do

first 30 minutes of my day, I do email catch up before my stand up. After the stand up I take about 15 minutes to update the KanBan, and then thats it for my admin tasks at that point. I may check email again (well I almost always) about half an hour before I leave for the day. The only exception is specific flags I have set and those will always notify.
