> For reference, 5,000 IU is >800% the FDA daily recommended value.

Unfortunately the daily recommended value was established erroneously and should be much higher. Many research papers mention this. For example:

> The Institute of Medicine recommendation for adults younger than 70 years of age is 600 IU of vitamin D daily. We are told that this would achieve a level of 50 nmol/L in greater than 97.5% of individuals.6 Regrettably, a statistical error has resulted in erroneous recommendations by the Institute of Medicine leading to this conclusion and it might actually take 8800 IU of vitamin D to achieve this level in 97.5% of the population.7 This is a serious public health blunder.

You are choosing really bad examples, because Republicans are even more extreme than the Democrats on them.

Homelessness is an infinite money sink coupled with very problematic civil rights issues. It takes a unified effort at the federal level when states are willing to just ship their problems to other states. It also requires a unified effort at healthcare--both physical and mental. Nobody has come up with a good solution to homelessness yet--anywhere. If you have one, put it out there as lots of governments are desperate for a fix.

While NIMBY is bad irrespective of party, the YIMBY movement only started gaining traction once the Republicans were purged as the NIMBY movement could COUNT on them as a unified bloc of obstruction. And, as for NIMBY, renters outnumber property owners, yet don't show up to vote. Well, then what results do you think you're going to get?

As for Texas, it isn't as uniformly Republican as you think. The major cities are gaining significant Democratic representation (the Republicans just banned straight ticket voting because it destroyed them in Houston last cycle). You can also see this in the Covid-19 response--the mayors for big Texas cities almost uniformly shut down--Austin declared very early in order to avoid the disaster that would have been SXSW.

Yes, the gerrymandering in Texas is horrific, and the areas outside the cities are as stupid red as it gets. However, Texas isn't as unified as you think--in spite of the human-shaped Senator known as Ted Cruz.
From one person who was born into poverty to another, I'll gladly call you ignorant because my version of your story involved me taking out a loan against my personal health in order to take a risk that either could've put me above water or doomed me.

I'm missing a lot of my teeth but it got me out of poverty. Do you think that was a good trade? Do you think it's a good thing that people have to make such decisions to survive?
It has been said before and should be said again:

I wouldn't say nitpicks are necessary changes in most circumstances - they are really soft suggestions about very fine details, I tend to describe them with optional non-blocking comments. Nitpick is a really good term for them but "aesthetic" might work as an alternative, there isn't a huge glut of words in that realm though.
Oh interesting. A bit dark, but I've noticed many prisoners have a set routine of constantly cleaning their surroundings. Possibly because it gives them something to do.

Vibrating Clothes Could Alter the Perception of Your Own Body
Great, and the WHO is welcome to keep the doctors video off of their platform.

Ignoring ramifications of politicization, How many developments will be missed if we embark on a campaign to suppress all dissenting opinions?

You don't think a doctor on the front line is qualified to make inferences about the disease that he is literally treating en masse? You don't think direct observation and experimentation with hundreds of patients could provide valuable insight into the properties of this disease or potential working treatments and/or best practices? How far backwards are you going to bend to defend this position?

Again, the fact that this particular decision agrees with your preconceived notions does not mean that YouTube's emerging practice of choosing truth is good for society. The WHO is also not the only qualified body, nor is it a final authority, yet here YouTube is suddenly treating it as one and, conveniently, YouTube's political slant is aligned with this particular decision. If we allow this behavior, it won't be the last time that YouTube picks a winner and shapes the reality perceived by millions of people. This is a possibly unprecedented amount of soft power and it is being used without oversight or control by the society that is being influenced by it.

I'm not suggesting we make it illegal but educated citizens should be at least resistant to the idea, not welcoming of it because it happens to agree with their politics now. The same goes for Google and FB and any other platform that acts as a window to information - these corporations are not authorities and should not be gatekeeping information. Long term that's a far greater danger to society than COVID19.
On the "auto auto", I'm pretty sure I filed a bug report on that. There are alternate D docs that don't produce the "auto auto" (and it goes without saying that it isn't that way in the code itself).
India has some of the densest urban environments on the planet... Mumbai, Calcutta, Howraw, etc.

And, it has pockets of density that are mind-boggling, such as the slums at Dharavi. 9 to 10 people in a room, families taking 'shifts' in the same living areas, 100+ people per latrine in some parts.

Yet, absent a massive cover-up, no reports of mass deaths.

The same goes for many of the world's other dense cities: Manila, Caloocan, Port-au-Prince, Kathmandu, Subang Jaya, Tokyo (not to mention the dozen or so 10mill+ cities in China.)

When this is mentioned, the response is invariably that "they have an amazing lockdown system with state-of-the art contact tracing." Or, "well, THOSE people are very submissive and obedient to authority."

It's not believable.

What does it even mean to "lock-down" Dharavi?! That's absurd...

Millions of deaths were predicted.
There aren't millions of deaths.
Great. The lethality of the virus was grossly over-estimated.
Yet, instead of happily acknowledging this, there are some bending over backwards trying to maintain that the Virus magically avoids places like Dharavi (or homeless camps in LA, or San Fran, or the elderly-populated Florida) because of government pronouncements.

I don't live in Dharavi. I've been there. And, I know there are plenty of people from India on this site. Maybe I'm wrong, but I cannot wrap my head around ANY lockdown policy that would make a rat's ass worth of a difference to virus spread in Dharavi. Ditto for Mexico City, the slums in Monterrey, Lagos, and the urban/slum sprawl in the metro areas of S. America.

It seems like they're rolling all their platforms (Instagram, Messenger, WhatsApp, FB Main) into that one metric? HN's position has generally been that FB Main is on the decline and I'm not sure this metric is enough to contradict that.

A few questions:

1. What are the top few things in the protocol that improved speed upto 6x in comparison to ngrok?

2. Is Lynk based on your earlier work on Parasite?

3. The website claims "CDN-like performance" with "highly-available load-balancers" over the tunnel, and so:

3a. Is the limit on number of connections (100 to 200 per minute) a soft limit? Can it be raised? If so, by how much?

3b. Do you have servers across the globe like CDNs do? Or, plan to?

4. I see a flat $5 fee for enterprise usage and a notice about "no tricks pricing"... Is bandwidth something you monitor for "fair-use" and might charge extra for? Or, is bandwidth simply unlimited?

5. "Lynk Web UI for Request Capture and Playback" Neat. And so:

5a. This works for both TCP and HTTP? Any video/screencast that shows this in action?

5b. Is the HTTP tunnel a reverse-proxy or in fact a HTTP CONNECT tunnel or something else?

5c. Does TCP tunnel over SSH? Or HTTP? Or both? Or neither?

5d. How do you deal with TCP over TCP performance issues, if at all: https://github.com/apenwarr/sshuttle/blob/master/docs/how-it...

You might want to update the FAQ section of your website. It seems to be out-of-date.

Thanks.

The plural is virus is viruses, or "virus" if you insist on its Latin form. It's a Latin word, but it only occurs in Latin as a singular collective noun:

Just like his "400 mi range BMW", I fear George will find himself on the wrong side of history.

Let's start with cars: why has George gone out of his way to put down Tesla, lumping it in to his "not-a-new-product" category, and decided to purchase an objectively inferior electric vehicle (BMW)?

Maybe he likes the look of BMWs. I hope so. Or maybe he cannot stomach Tesla because it represents the exact antidote to his entire argument: an "incremental" product that requires no marketing or writing to easily outsell the competition. If the future looks like a world where there are no "new products" and great writing will be the meaningful differentiator between products, why has Tesla decided to forgo writing altogether, great or not?

He makes a few salient points on the outskirts of the article. But the crux of his argument is "good writing goes beyond almost anything outside of real transformative technological leaps," one of which is not Tesla, as noted earlier.

If you had to bet the future of societal progress on improving products vs. improving writing, which would you choose?

If the future of advertising follows the future of autos, then I'm sorry but George will be out of a job pretty soon here.

For all the hackers that get scared by these articles and run out to take a writing class: don't. Focus on creating great products. As Elon does, let the products speak for themselves.

Also George, small typo in paragraph 16: "I called by system "the three Ds.""

Thanks! There's already a Go client: https://github.com/saljam/webwormhole
The biggest pain is that both DBs are extremely limited. You can't search for example. No joins, relations, or anything remotely fancy. There are some very very basic filtering capabilities but other than that you either load all the data in the client and do your work there, or you use a proxy (cloud function, node server, etc) and lose realtime and sync. Or maybe use Elastic on top [1].

Most of your Firebase logic will live in your client(s). If you have multiple clients (web, iOS, Android, etc) you will have to write and maintain the same logic multiple times in different languages. And since the DBs are so barebones you will need a lot of logic to read and write. Pretty much all the business logic you'd have in a server will be in your client(s).

You also have cloud functions which have the worst dev experience I've seen with serverless. Deploying takes forever, sometimes as high as 2-3 mins, and you will need to deploy very often as most of your functions won't run locally [2]. Debugging is done via the Firebase console which is a painfully slow Angular 1 app.

For websites the complete Firebase SDK is 215kB gzipped and you will need most of it [3].

You can define database rules using a JSON-like language for permissions and schema but it will get super messy as your project grows and become unmaintainable.

Unless you are doing a small project or a prototype get as far away as you can from Firebase.

If you do need a serverless DB look into Fauna DB which gives you everything you expect from a serious DB. Or if you're looking for a zero-config backend look at Hasura like I've mentioned earlier.

They went from individual stampings welded together to very large die-cast parts.
Well reading/writing level are going down. Anyone who thinks, just because they've graduated from some famous college are going to absolutely obliterate competition in business are wrong. You need a language which most of your customers can easily understand and most of the times those who come from outside of the industry but have superior knowledge of language make fool of themselves.

This is as someone who doesn't know much about English but have built a company for English speakers.

Sure thing! A couple keys differences:
1) Avatars - as you mentioned
2) Walkie-talkie - most virtual offices have a call analogy, where you call someone to speak. In Pragli, you don't call - you just jump straight into a conversation, but the other side is muted (to protect their privacy). Here's my blog post on this: https://pragli.com/blog/building-a-walkie-talkie-for-remote-...
3) Some solutions have a very literal office (with a floor plan, etc) - we have a more virtual analogy
4) From what we hear, we have higher quality audio, video, screen share than others (I encourage you to evaluate for yourself)
Like, I totally agree. Frankly, you're so right. Know what I mean? People really write too many words, basically, to say something they could express quite readily in far fewer words. Man, sentences go on and on saying the same thing over and over. I'll be honest, this is wearying and tiresome to read. Can't people simplify and get to the point? Do people even bother to read what they write? Too be perfectly honest, this is tiresome and tedious.

God. I remember reading this a year ago.

I've been working on TinyDev for about...two months longer than I thought I would have, and I still have probably a month left to go before it's completely ready. Just the amount of ops work you need to do in order to lock down your stack is absolutely insane. That's assuming you invest in ops work in the first place, which many places don't, hence technical debt and war rooms and fires and the slowness of project management resulting in massive backlogs and the like.

I'm going to do a writeup hopefully up this weekend on backend level to VPC level work, just so that I can lock in my learnings. What I can say now is, the only easy day was yesterday.
Covid19 a Disease of the Endothelium
As an investor, I like the format these results are presented in. The slide deck approach is a lot more approachable than the typical text-only SEC filing. An average investor is much more likely to open this and read it than the typical financial statement. It's not over-the-top marketing agency gloss, but it has some nice touches. Of course, you also get the text-only filing to follow.

As far as the key numbers, Tesla continues to push profitability and I think beat estimates by pulling off a profitable quarter in Q1. I can't imagine they will do it again in Q2, and they've suspended their guidance, but compare and contrast to, e.g. Ford, which is currently drawing all their credit lines to the max to stay afloat (to the tune of $15 billion).

They've never had spare inventory before, it will be interesting to see how fast they can clear it when things pick up. In a very long shutdown scenario, Tesla will come out way ahead of standard auto makers because their cars somewhat forego the "New Model Year" craze, and they can software update all their inventory. So while most carmakers will be looking at bursting full lots of "late model year" new cars, Tesla will be selling "Model 3" and "Model Y" through their configurator same as usual.

It's been fun watching the Munro tear-downs of the Model Y. I'm curious when and how quickly those improvements will make it back into a redesigned Model 3. They have definitely improved and simplified the design in important ways. They highlighted this in their slides at the end showing underbody components of Model 3 (70 pieces) vs Model Y (2 pieces, eventually 1).

Solar is unfortunately MIA in this report. Buffalo managed to get Solar Roof ramped up to 4MW per week (1,000 homes per week) just as the shutdown hit. I would imagine a lot of momentum has been lost in their installer recruitment and training efforts. I would have been very nice to see some ROI in 2020 from Solar Roof, but I'm not sure we'll get it this year.

Looking forward to getting to see a Model Y in person and feel how much more space it has. It seems like they've left a good deal of acceleration "in the tank" to unlock in future software updates, that will also be fun to see.
Also very overpriced, imo. But it seems like e-ink displays are expensive in general.
