A good fix requires the whole system to be re-imagined a bit. You want to start with the invariant that a stablecoin holder can liquidate to Eth at any point, and that a collateral issuer can extract their Eth at any point.

Instead of having the collateral provider be the only one who can issue the stablecoin, you could build a system where anyone could acquire the stablecoin (Dai) by putting in an appropriate amount of Eth.

Any extra Eth that gets put into the pool will issue a volatile asset, which I'll call Vai here for simplicity. Where Dai has no exposure to volatility, Vai has increased exposure to volatility. As the Eth price rises, the amount of Eth that Vai can be redeemed for increases, and as the Eth price drops, the amount of Eth that Vai can be redeemed for decreases (this is the opposite of Dai).

At any time, Eth and Vai can be redeemed for Eth from the pool. As the price of Eth moves around, the pool becomes over-collateralized and under-collateralized.

If at any point the pool becomes under-collateralized, all Vai becomes worth zero, and all Dai can redeem Eth proportional to the amount of collateral that there is. Meaning, in a "black swan" scenario, Dai holders become exposed at 1x to the price volatility of Eth. This is much better than the whole system melting down, and the Dai holders do get to dodge a significant amount of the downtrend while the Vai evaporates. (Dai holders see no exposure until all the Vai is gone).

You can keep the pool balanced using interest rates. If you have a target collateralization level (say 150%), then any time the pool is under-collateralized, you can automatically drop the interest rate that Dai holders earn (going negative if necessary). If the pool is over-collateralized, you increase the interest rate.

A lower interest rate encourages Dai holders to withdraw and Vai holders to enter. A higher interest rate encourages Dai holders to enter and Vai holders to withdraw.

-----

The most important thing about the system above is that it is highly predictable. In all scenarios where the price of Eth moves, you can model what happens, and you have guarantees on how much Eth you can draw, and you can withdraw that Eth immediately (well, you'll need to pay blockchain fees and wait for a block, but you don't need a counterparty or any sort of system liquidity). The worst case for the stablecoin holders is that they get exposure to 1x Eth, but this only happens if Eth drops faster than people deposit Vai.

There are a bunch of math tricks you can use to allow people to select different exposure levels (you could have some Dai targeting 250% over-collateralization, meaning it's very robust to huge drops in Eth price, and other Dai only target 15% over-collateralization, and these two assets could be fully fungible against eachother) for Dai holders and Vai holders, but we are getting beyond the scope of a single HN comment.

We are not killing the planet, but we are putting ecosystems under pressure.

And evolution has given us tastes for things that are highly nutritious but were difficult to come by. Shall we deny ourselves these pleasures because they become problematic at scale? If so, what else should we ban by the same logic?

Perhaps the main problem is that there are too many of us. Or maybe we should be putting more effort into growing meat in vats.

Whatever we end up doing, I doubt it'll end in some kind of sustainable balance. Rather, we'll continue to multiply and consume as much as our technology allows and the environment can bare.
The nature of BEAM as a distributed system makes it hard to guarantee anything. If another node running code outside your analysis set sends you a message you can't know what it will be at analysis time.

There could be many reasons for the sending code to be outside your analysis set. The sending code could be in another distinct code module (perhaps in a 3rd party library). The sending node may be running an older version of the code. The sending node may be running a newer version of the code. Something terrible could have happened on the sending node.

> ...astounding achievement from Redmond. It boasted interactive tools to create GUI drag and drop features users were accustomed to in VB6 but glaringly missing in the Java world. This was with Visual Studio 97

Thay were not "glaringly missing in the Java world" in 1997 when Visual Studio was released. By that time at least these 2 IDEs with "drag and drop" were released and used already: Symantec Visual Café (a good one!), and a beta of IBM VisualAge (second part of 96). VisualAge came with specific ibm's understanding of drag and drop, however the Visual Café's experience was really similar to VB and much easier than J++ from what I remember. I tried all of them at the time including JBuilder and Sybase. JBuilder was my best for quite time.

It’s totally possible and is half as hard as you think. Some concrete example, this is the diet of 6 time world F1 champion Lewis Hamilton:

You do need to take care in having good diet, like taking care of protein intake, B12, omega-3. I personally prefer a flexitarian diet, where meat is rare, mostly vegetarian and vegan when I want to.
Thing is, you don’t need meat every day, and just halving it makes a great difference already with minimum effect on your health.

I know that. But guess what, that other person is out in public too. If their risk tolerance is such that they absolutely do not want to get sick & risk taking it home to their elderly parent, well that’s fine but, they need to self quarantine. My point is I have a higher risk tolerance level in terms of contracting the virus from a non-symptomatic stranger in public because 1) i don’t mind being sick enough to limit my activities 2) I can control my exposure to high risk people except in public spaces (again, if you’re high risk, why are you in public - that’s on you).

What you all are implying is that anything less than complete mandatory quarantine is the correct course of action. I just don’t agree with this doomsday situation given what I know about this virus at this point. Even 2 degrees of separation from confirmed cases isn’t being taken this seriously by the CDC/medical community. And you’re essentially telling me I’m an idiot and negligent/malicious person for going out in public with no other reason to believe it’s unsafe. I just happen to believe nobody is negligent in these situations and the responsibility lies with those at risk to reduce their risk profile.
Ask HN: US-based hosting or local country?
I run an Aussie flight search site. It's currently hosted with a cheap US hosting company (hostgator) I chose when I set it up because, well, cheap.

What I'm wondering, as my hosting subscription is coming up for renewal:

1 - does having a server based in Australia make much difference to speed?
2 - does Google penalise slower sites?
3 - does Google take into account that if you have a .au domain, it should speed test for Aussies?

Basically, trying to get advice on whether it's worth moving hosts - the few website I've found discussing it try hard to push you in a particular host's direction, and then you see their affiliate code, which makes it harder to validate :/

I have had a couple of physician friends describe it as “just a really nasty flu” as well. However, I couldn’t square it with the seriousness with which I was seeing th authorities address it. That’s when I realized, that the comparison is misleading. For example, you could describe a lion as “just a really nasty cat”, but that wouldn’t be doing it justice.

If the 2% fatality rate is accurate, compared to the flu’s 0.1%. That is 20x worse. The other scary part is that we don’t yet know if this virus is going to be seasonal like the flu.

Lab breaks of SARS, another coronavirus have happened a number of times, and likely caused the original SARS outbreak (according to WHO)

This regional phenomena happens to be right across the river, 20 miles, next to the only BSL4 level lab in the region.

That same lab also happens to have published hundreds of synthetic coronavirus genomes. They also ran gain of function research that was banned by NIH until recently, due to it's highly questionable ethics and biosafety in principle.

It's just another lab break, why is it so hard to accept that industrial accidents happen?
Toronto now has open boarding (i.e. you can enter at any door) through all its streetcar lines and many bus lines. The new streetcars have totally separated the drivers from the passengers, so payment is more of an honour system + fare cops* proposition, compared to the old "show the pass/pay the driver" paradigm. Boarding speed and fare evasion have both increased.

What word? In normal discourse everyone knows you're talking about long term policies so unsustainable equals impossible.
I think the point they were trying to make (and it's one I share based upon talking to operators in a few of the largest broadband networks in the US about their usage) is that the WFH crowd is not moving the needle in terms of driving traffic. Except for the 10th which was Call of Duty updates that did congest networks starting in the morning the peak is still post 5PM. Now with schools being closed that can certainly change and lead to what many broadband networks spot during spring break (peak coming sooner).
Wow, that's an interesting hypothesis! I just pulled up a random wordlist on GitHub (370k words) [1]. Searching it in a text editor, "ght" appears 1621 times and "gth" only appears 77 times! So perhaps habitual mistakes like these really are caused by the higher frequency of a different ordering of the same letters.

I’ve been told I’m inciting panic just for dispassionately commenting on friends and acquaintances Facebook posts.

Because of the distrust in our government and institutions, people won’t believe anything until it’s way too late.

I’m also frustrated with the “happy talk” people, who think if we just stay positive, everything will be fine in the end.

I’ve must have explained a dozen times the difference between what happens when a virus has a mortality rate of 0.1% like the flu vs. Covid19 (on average) at 1–3%, which means it’s 10–30 times more deadly.

That's a hard call to make. IIRC income and land taxes were each supposed to be temporary funding solutions for wars and such.

On the other hand Trump had the right idea eliminating bloat but he went about it in the worst way. That way we'd be less likely to end up with more permanent taxes if this drags on.

It is odd, and it could hint that the virus escaped the lab. It could also hint that a foreign power decided to release a pathogen there to disparage the government. It also could just be a coincidence. I don't think it benefits anyone to speculate. We will probably never find out the truth behind it.

It’s neither helpful nor actionable advice. By the time I read this, I can’t make any “liquid assets” magically appear, neither right now nor in time to be useful. (Assuming you’re referring to savings, i. e. money.)

I'm surprised to hear someone be so blunt about their ageism.

Yes, in general, your server should be as close to your customers . . . but if you're calling into a lot of backend services to do flight searches, you may also want your server to be closer to your backend services (maybe they're in the US).

There are already many, many apps for that.

Google Maps will give you some decent good route mapping and alternatives, though less realtime than apps that use data back ends like NextBus.

You can do better routing than Google if you're familiar with a route/combination and its intricacies, but if you're in a part of town you don't know as much, Google Maps' transit routing is a godsend.
The maximum download speed for DOCSIS 3.0 is 1216 Mbps, and that's only if you use 32 channels. If you were selling 200/6 connections to 72 users then you would be only guaranteeing them each ~8% of the download capacity (and yet 50% of the upload capacity, using 8 upstream channels).

To have the same level of oversubscription for upload as download, you would give them all 35Mbps upload with the 200Mbps download. But you don't even have to do that, because who says they all need the same plan? Sell a quarter of them 100Mbps up connections and the others still get 17Mbps up.

No way to justify why it should only be 6 up if it can be 200 down. (And if they're offering 200Mbps down without that much oversubscription by using DOCSIS 3.1 or 4.0, even less excuse for 6Mbps up.)
The YouTube video library is huge so they're prioritizing encodes based on encode time (AV1 takes longer to encode), the ability to play it (more systems can play 480p AV1 than can play 4K AV1), and the number of views a video gets (if a video has a low view count then it doesn't much matter what it's encoded in).
