I still think it's a miracle that the browser was the solution to the client-server problem x-windows was trying to solve all along.

X was the solution to the problem MIT had, and as such, the problem X was trying to solve. It worked very, very well for what it was trying to solve.

How we ended up with billions of people able to interact with an app that we can all build at home seems insane...

Java. Java did this. On billions of devices! Everywhere from your smart card to the mainframe. Before Java, Dis! Before Dis, Forth! Good luck running a web browser plus your application on a smart card, or even (decently) on an underpowered netbook.
Independent schools were always for a small minority. Among independent schools I’m reasonably confident boarding schools were a majority. They were not for an elite. They were for the economically successful, a middle class much smaller than what we have now but it was not unusual in small town or rural Ireland in the ‘60s for the children of shopkeepers or successful farmers to send children to board for secondary school. That’s a definition of elite so expansive as to be meaningless.
It’s not just that. Being flush with cash causes engineering bloat. You start chasing blue sky trendy ideas (AirBnb was reportedly doing chatbot for a while, ala Volara.) or chasing more and marginal gains on existing products. It’s inevitable, when money is cheap.
In which case, the grandparent’s comment is likely not useful advice.
The reporting is a little off.

It's says an $18b valuation is "a drop of almost half" from $31b. OK, almost.

Then it says all of the $1b is debt which would not suggest a new valuation.
The poster said "I find that...", which is equivalent to "In my experience...". How is someone posting their experience the same as making a "sweeping over-generalization"? They never flat-out said "ALL textbooks".

Also, surely if it were not accurate you could easily drop the name of a good textbook without any trouble, since you apparently have enough experience with them to make the distinction.
I think a solution would be to let the video on the platform but display a huge yellow banner or something like Reddit's quarantine thing where it says "this video contains misinformation about Covid-19" or something more intrusive if you'd like.

> Because the defining feature of technology is essentially low marginal cost at scale

Outside of the current crisis I think this holds true doesn't it? I'd be curious to compare how many employees AirBnb has per bedroom compared to a hotel chain (and then factor in that they are still in the process of scaling).

The issue now means they have pretty much zero revenue, but that's kind of beside the point. I'd venture to guess they can manage costs better than a hotel since they don't actually own any buildings, or employ the folks that maintain those buildings. As far as property costs, they take a one time hit on cancellations.
I find it the opposite. Lisp is much easier to write than, say Go. I think the problem is if you're used to the complexity of writing a Spring Boot app (Java) this simplicity of writing in Clojure will confuse you: you think it can't be that simple when in fact it is.

I used to freak out when I'd find the library in Clojure I wanted to use but it had no documentation. Eventually I just started looking at the implementation and I'd see it's like the entire library is 35 lines of code! Or like 102 lines of code! You don't need documentation for something that small.

I've never seen this before in other languages. If you think it's too complicated, you might just be overthinking it.
That's why you store a "name" field, and then spend the rest of your carrier writing parsing logic to answer silly management questions.
I believe restricting recommendations to books one has read would shrink and improve this thread.
The other way you have to leave the Clojure ecosystem is when you have to communicate across the network or persist to disk. Writing everything fits in memory data analysis in Clojure is some of the cleanest and most fun programming I've ever done.

But once you want to spread between multiple computers or operate on data larger than what comfortably fits in memory, you end up coding just like you would in C#.

I started working on some versions of persistent data structures that serialize to a KV store, which lets you send a hash map to another machine, have save that machine add a key, then send it back. It seemed to work pretty well, but there's a ~10x performance penalty over Clojure's inbuilt data types (which are themselves not lighting the world on fire speed wise).

That's a pretty harsh price to pay - you can use 100 machines to simulate single address space Clojure on a 10x machine. Awesome, but likely impractical. If you need the persistence between program runs or would like to run incremental computation on large data I could see it working well, though.
"The investors will also get warrants that can be converted into shares with a valuation for the company of $18 billion, a drop of almost half since Airbnb’s last fundraising in 2017, the people said."

This indicates they'll get twice as many shares for the money as previous investors. Hence a ~50% drop in valuation.

In my experience, getting to the "next level" always requires building something substantial. Just like trying to speak or write in a foreign language is always better than learning about that language.

If you feel like you want to grow as a programmer, pick a project (or contribute to an existing one), and learn whatever is needed to do it.
The post office isn't really similar to the DMV or NASA. While it's not a private entity, it's supposed to be run like a corporation, in some ways similar to Amtrak. USPS is okay I guess, but Amtrak sure does suck.

How comfortable with doing a lot of the work of maintaining the web server yourself are you?
I've tested this with a couple of test accounts. By default the e2e rooms history are set like this:

Who can read history?

Members only (since the point in time of selecting this option)

but this option doesn't seem to work for me. The history didn't synchronize when i added my own homeserver account and verified it with other accounts - do i need to import the keys from the old account first for it to show up or am i misunderstanding how this option works?
Yeah good point I find myself often having to use a Clojure shim over a not great Java library out there. It's painful at first but it can be really great once you've tamed that beast.
FedEx and UPS live and die by volume. The more packages they move in total, the cheaper it is to move each individual package. They can then make their profit in sales to companies and individuals with far less volume and pricing leverage than Amazon.

For the sake of argument, let’s say that Amazon makes up 50% of UPS’s business, and those packages are shipped by UPS at a 10% loss. If the other 50% of their business averages a 20% profit, then they’re averaging a 10% profit across the board.

Without the Amazon packages, let’s say UPS can cut their operating costs by 25%. Now they’re shipping 50% as many packages, though, so the per-package operating cost has increased by about ~33%. Those customers that were generating 20% profit when the network was larger are now a losing proposition. UPS then faces the choice of downsizing their operation or raising prices. Both of those options are about equally bad when you consider that their competitors are not impacted by the loss of Amazon’s business (well, to be totally correct, their competitors have already absorbed the disruption to their operations when Amazon pulled their business to move it to UPS in the first place).

To be clear, I’m not saying the above numbers are correct - or even close to being representative. I’m merely illustrating why it makes sense for transportation companies to take large-volume customers even at a loss.

A carpenter friend came up with a similar design a couple of weeks ago. His slides over the visor of a baseball cap. He sourced thin plastic sheets, created a form, then made thousands, and sold them all to an org in B.C., Canada. Great minds think alike.
I think a better comparison would be to try inhaling wet steam (i.e. a suspension of liquid H2O) from behind a face shield. You'll probably inhale some, but a lot of it will adhere to the shield.
SF and the Bay Area's housing problems predate AirBnB becoming popular. There just isn't enough supply and regulations prevent building more.

I might agree if you were talking about Barcelona or Rome or something like that.

Cool technique that uses existing Sanger sequencing equipment that has been optimized for decades. So you are sanger sequencing the loci + a synthetic frame-shifted oligo that you spike in. Then you essentially "demultiplex" the chromatogram knowing the two molecules are frame-shifted and compare the peaks to get a relative measure.

I guess the trick is to find a loci that is specific enough to covid-19, but can still produce a good frame-shifted oligo that allows you to maximize the resulting chromatogram signal.

I am surprised that the detection limit of a no-extraction PCR can be this sensitive. But it looks like the data checks out. Does this work for every type of sample? I would assume differing buffers, collection methods will influence the PCR?
I wouldnt offer air bnb a billion for 10%. I dont think they can pay it back. I hope they can't pay it back. Dublin Ireland saw 67% more housing available overnight because air bnb home owners needed to offer their homes to long term stayers since the travel ban. They're a nuisance.

I don't know. It just seemed like a funny, evil idea that I could test my skills with. I wasn't that intent on actually making a business around it, though I won't pretend like I wouldn't have tried if I thought I could make millions. The person I am now definitely would be totally against such a thing.

I get where you're coming from. I guess just the problem domain I'm in, and my experience level, I tend to get what I expect from a model, and if I don't I'm more like, "wtf?" which isn't anywhere as fun of a way to do that part of the process.

Also, I know what is possible and impossible before I start writing code (if you don't count EDA code). There are exceptions, like it should be possible but it turns out the data is bad, but it didn't look bad from the EDA. Thankfully I've never had that. I always perform a Feasibility Assessment before anything else.

Not to imply what you're doing is somehow incorrect. Problems can vary quite a bit and I recognize that. For example, there have been times where I've had to mine to see if anything is there, doing ML over it to validate a hypothesis then using that information to create a new hypothesis, rinse and repeat. That's scary, because I could turn up nothing. I haven't done a lot of mining I admit though. Usually my problems are much more obvious from the get go, or much more research intensive.

One time I did three months of reading papers on arxiv.org just to figure out if something was feasible and how to best do it. Though that was definitely not a standard problem.

3-6 months worth of operating expenses is in no way a “massive emergency cash fund.” Around half of that 6 months worth was in cash or cash equivalents (I don’t remember the exact numbers offhand), not shares or other investments.

You’re actually proving my point when you say our expenses are high relative to net profits. If we can do it, and still be growing at an adequate pace (we grew earnings at, IIRC, 8% last year), what can’t other companies? Before, you claimed it would stifle growth We have way more software engineers on staff than financial engineers. I find it hard to believe we can do this and other companies can’t. You haven’t given me any reason why they can’t, either.

And, BTW, if repurchased stock is so liquid, why are these airlines crying now? It’s because either they didn’t adequately insure against a systemic risk to their business, or they canceled the shares.
I thought net neutrality is “all bits are created equal.”

Service providers shouldn’t discriminate between one bit and another - no deals that prefer some providers or traffic over others.

It usually refers to ISPs, but I don’t see why it doesn’t apply to cloud providers too.

Airbnb is in a LOT of trouble if this pandemic fear persists for a while. Forget the obvious drop in casual travel, it's going to be hard to compete with hotels that can claim 100% control over their properties.

I can already picture the Mariott ads promising "100% sanitized rooms and common areas".

Can Airbnb guarantee the same? Not by a long shot.
The risk is very high, my wife is a nurse here in the UK and is infected. Fortunately she has light symptoms and a light cough. When I am with her we both wear a face mask, but there is no need for a shield because I’m not intubating her her or at risk of heavy splatter from close range explosive coughing. Again, even doctors in hospitals only wear face shields under specific circumstances, which are situations the general public are not likely to find themselves in. That’s why you don’t even see doctors and nurses wearing face shields in public or taking them home. Outside those specific circumstances they don’t need them, and we don’t need them.
1. Not unreasonable. But it minimizes the risk of you spreading the disease much more than you getting it. Infection can also occur through eyes. Some places have fines for not doing so already... Check your local authorities and infection levels.

2. Not unreasonable, can indeed hurt:

Gloves and masks can also carry the virus onto other surfaces if not used or disposed of carefully.

3. Can't hurt. Possibly too much. I havent seen a study of virus spread on non-porous surfaces.

The virus seems to survive around three days in plastic, for example. Some are considering careful introduction of groceries to the house.

4. Cant hurt, but soap is likely better than alcohol.

5. Cant hurt.

6. ?

As a driver I typically don't have your phone number. The times that it is on the package, I will call you if anything is out of the ordinary. I'll call you and then if that doesn't work I'll leave a voice mail and follow up with a text message in the hopes that you'll get back to me while I'm still in the area/before the re-attempts the next two delivery days. Most times I'll call another driver before I call the customer, because they'll likely have knowledge of the area. In my hub they try to keep the drivers on the same routes or, in the very least, on the same loops (groupings of routes). When you learn an area everything goes much more smoothly. In your case I would consider calling UPS and getting in contact with one of their Operations Management folks. What they can do is add a short note about the location of your door to the scanner, so that a driver who is not familiar with the area is able to find it. If you get ahold of one of the drivers they can also let the Operations workers to add that sort of note.

>I don't understand why FedEx and UPS can't do this.

Amazon can be reasonably certain that the consignee is also the person that ordered the package, and they have that person's phone number. FedEx and UPS do not have this luxury. I've called numbers for alcohol deliveries (Under no circumstances can I release the package to a neighbor or just leave it) and instead of the consignee I was put through to a winery out in California. Thankfully they got in touch with the customer and had them divert the shipment before I had to return to sender the package.

Viruses don't diffuse through the air like smoke. Viruses are contained within the aerosolised droplets of your bodily fluids that are ejected through sneezing, coughing, blowing the nose. The survival of the virus outside of the body exposed to the elements is limited. Viruses have limited lifespans and can only reproduce within the medium of the bodily fluid. Every virus has different characteristics, and may have a longer or shorter lifespan. These characteristics are more or less universal for viruses though.
It's not impossible for them to travel longer distances through the air. For the most part they are limited to the initial propulsion from the body. A better analogy would be spraying an aerosol can and watching how the droplets settle.
