Kvrocks: Implement the Redis Protocol on Rocksdb
Hey, thanks! My bad.
It's very important to understand that RAID is not a backup solution. You still need to backup even if you have RAID, no matter what level.

What it offers (in parity mode) is improved reliability and more chance that your server will be online if your drive dies. In majority of cases, it saves you from restoring from backup. Just replace the bad drive, and away you go! However, never assume that it will protect you from data loss. Backup. Backup. Backup!
In no way whatsoever is that writing style elegant, terse, or vivid. It’s an angry puerile rant.

Why use a userscript when you can use a search engine that is not from a spyware company? Like Startpage, Qwant, Duckduckgo or Searx? Alleluia, direct links out of the box.

Sometimes, the best solution to "hostile websites" is to not use them in the first place (or use their proxified versions).

I once used the word snib in conversation in England, and got blank looks. I then realized I didn't know the Standard English word. After describing one, I was told it was a latch. Other words I prefer that would draw blank looks are skelf (splinter), bike (wasp's nest), and oose (fluff).

To have paid staff manually micro-regulating like this isn't what I call a solution. You're simply prodding the herd with a stick, and your message is virtually drowning amongst the other ones.

You cannot be imperative, top-down to a community and expect that to work.

"For discussion purposes, moving from Beta to RC doesn't make a new topic" <-- kinda trying to convince

"For the purposes of HN threads, there's no difference" <-- almost resorting to authority

That tone and kind of discourse is ... unfortunate.

It's similar to the Wikipedia principle, don't say something is amazing, explain WHY it's amazing. Then you will perhaps convince 10s or 100s of people that will not enforce your rules but perhaps convince other members of the same. I just hope your rule is right :)

In other words, a community cannot be sustained by being regulated by privileged people, poking them here and there. A community needs to regulate itself and their individuals need to grow themselves.

By the way, such a (humble) message would be worthy of being colored in a distinct way to give it more priority.

But given the abysmal lack of development (and also the current state of features, ew) on the HN site, I doubt that such a feature would ever emerge. In fact, the only thing that makes HN worth visiting is its users. The website itself is horrific.
I'm not sure what's college level physics like, but for me (math/CS background) learning quantum physics was:

- Quantum algorithms and computing: "Quantum Computing Since Democritus" by Scott Aaronson [0] and "Quantum Computation and Quantum Information" by Nielsen and Chuang [1]. "Quantum Computer Science" by Mermin is really good too.

- Leonard Susskind's lectures on quantum mechanics [3]

- "Introduction to Quantum Mechanics" by David Griffiths [4] -- just your regular QM textbook. Recommended by many and I found the explanations clear and easy to follow

- also there are some recommendations by John Baez [5], that I've personally not checked out, but when Baez recommends something, it's good!

Note that I'm not a physicist and doing it only for fun, so would be interesting to hear from people with proper physics education!

There's one thing I cannot wrap my head around.

Math is purely abstract science yet it describes the world around us to the utmost precision. Does that mean that this world is simply ... a math model which means everything around us is ... not real?

I've long stopped believing in free will because everything points at it being an illusion of our brain because we're a product of this world and we had no chance of influencing the conditions which brought us to life, and even after our minds and consciousnesses form it's hard to believe they are fully autonomous and not simply a function of the processess in our brains we're simply not aware of.

If you think about all of it, it becomes utterly depressing as you begin to realize you're a biological robot, a byproduct of the universe evolution which couldn't care less about our species and this little tiny blue planet.

It ossifies the namespace. As in, you can't have a name that is both reasonable and can coexist with the current DNS model.

Any of .onion, .bit, .coin, .eth, .crypto, .zil, can expect the .dev treatment, or, in time there won't be many nice available one for future developments. Similar issue might be with things like .ipfs, which don't resolve in the usual sense, but could cause confusion if there was an ICANN .ipfs domain.

Some domain trader will come and say those aren't "real" names, and you are supposed to rent them from ICANN, but that seems like a protection racket.

It is ignorance though, both willing and unwilling. It's ignorance at the bottom, ignorance at the top, and ignorance at every level in between. Even our "solutions" are ignorant.

Every improvement in energy efficiency we have ever made has resulted in more energy use, but we still cling to the idea that if we can make everything just a bit more efficient then that will do it and our problem will be solved. It's a lie and it's a scam.

A green new deal isn't the solution and it's our ignorance that makes us believe that it is. All it does is greenwash all of the toxic things we are already doing. We can't solve industrialisation with more industrialisation.

We can look outside of our windows now and see the solution. It's doing less, it's working less, it's not polluting the world, it's consuming less and producing less. Radically so.
Same here.

I spent a day learning and playing with Elixir around a year ago, and immediately liked it a lot.

But more main dev language is C#, and I'm very used to static typing - as much as I enjoyed Elixir, the lack of static typing was a problem for me, so unfortunately I chose not to take it any further.
In addition, this virus tends to prey on the weak. You don't want to have a pre-existing condition around Covid-19. If you look at the top causes of deaths in the USA in recent years then match well with C19's "favorite" targets. This instance, high blood pressure, diabetes, lung disease (e.g., COPD aka smoking), etc.

The last stat I heard was 40% of USA adults have a pre-existing condition. That's a significant amount of potential hospitalizations.

Depending on your volume, it's really not expensive to setup a legal entity in the UK. Since UK is leaving (unsure if EU financial access will continue) Ireland is a good alternative. A UK company costs < £100/yr to maintain. Depending on your volume, it may be worth exploring with your lawyer/accountant.

Perhaps there's merchant-of-record services too, that are incorporated in the EU and I believe legally act as an agent to sell your product.
I don't know why this comment is dead. It's an interesting idea.
>> Radio frequencies are also susceptible to hackers who can intercept signals, Islim notes, whereas visible light could be protected by opaque objects.

So the security hinges upon it being easier to block visible light than more conventional radio signals. Seems that a fibre optic is still more secure and likely to achieve greater range for the same transmission power.
It's more about facts and real science than feeling special. The people who are against vaccines want them to really be "safe and effective" and not just labelled as such.

Two things are needed for that to happen:
- a study comparing vaccined to unvaccinated (the data is already there, someone just needs to be allowed to compile it)
- a proper double blinded placebo safety study which was not done for any vaccine (source: Stanley Plotkin, Vaccines Deposition, Under Oath)

You can only reach this conclusion if you categorize math as "not real". If everything we interact with is a perfect mathematical object, I prefer to take that as evidence that all mathematical objects may be real, however abstract they seem.

Having known many people that believe vaccines can harm kids, yes, it can be a 100% real belief, not some cover.

That's why you recognize that it would not go well to attack this with physical force - the strength of people's reaction would not because they want to appear special, but because they honestly, 100% believe someone is trying to hurt their children.
The simple solution is delete before you add more specificity. Cut it back to the common denominator and cascade from there.

Of course, you can sometimes inherit a system that is one big specificity mess.

Report Says Covid-19 Patients Respond to Gilead's Remdesivir, Shares Surge
There is a large number of asymptotic cases which is quite encouraging.

In their preliminary conclusion they write:

"By adhering to strict hygiene measures it is to be expected that the virus concentration of an infected individual can be reduced to the point that the illness manifests more mildly, with simultaneous development of an immunity."

I wonder how they came to that conclusion. It would be great if it turns out to be correct.

You're incorrect to say that if anyone dies with Covid-19 that they're counted as a covid-19 death.

It's likely that covid-19 deaths are undercounted. Here's one example: https://ltccovid.org/2020/04/12/mortality-associated-with-co...

For a while the US was only counting deaths that happened in hospitals.

This argument -- that we're somehow over-counting covid-19 death -- doesn't hold because we can compare excess mortality this year against the previous 5 years.

> That’s not true of the flu is it?

Yes, it is. The figures that count covid-19 vs flu are available, and they use the same method. They look at death certifications and then statisticians code those. There's lag in those figures which is why worldometers don 't use that data.
They could just announce that if such a contingency is used YC will not do the pro rata.

> we didn't need them to.. fast moving with unknowns..

They weren't just slow, WHO helped spread false and misleading information, and one of their main reasons for existence is to combat this. If WHO can't be trusted as a source of information, what are they good for?

> If we wanted to complain about WHO and Taiwan

I only just found out about this, now the spotlight is on them. Now is exactly the time, as the main complaint is that the WHO has political motivations that interfere with its main objectives, and this is evidence of that - doubly relevant because if Taiwan weren't being ignored, other countries might handled it as well as they did.
While this is an interesting thought experiment, and the outlined problem is a real issue, I don't think the outlined solution is a good way to resolve it. The main problem here is predictability: maybe it's simply that I'm not used to thinking about CSS this way, but the proposed CSS rewriting parser means it's not immediately obvious how what I write maps to the end result.

It's entirely possible that I'm missing some of the benefit here, but it seems to me that scoped styles etc largely already solve this problem.
A Sailor in the Navy is anyone in the Navy, period.

Once you cancel out commuting costs, assume rent/mortgage debts have been erased for the relevant time period, and focus only on food, that $1200 could buy you 8 weeks. It works out to a bit over $20 a day. It wouldnt be comfortable living. In fact it would suck having cereal, pasta, and canned whatever 3 times a day. But you would survive. And if you want comfort you can always dip into your savings.

This is all assuming the crisis is managed well enough that it actually ends in 8 weeks. Part of that is communicating the plan so people don't think they are choosing a risk of sickness over certain famine. Someone like Newsom or Cuomo needs to do a presser addressing how they are making sure the lockdown does not ruin you if you're living paycheck to paycheck.
If there were content then there would be points to argue against.

This is the same vein of response I'd get from Obama, or really any politician who has every word they say picked apart by a dozen staffers trying to make sure the decision that's already been made stays made while not saying anything that will cause blowback.

I'm late, so you probably won't see this (might shoot you an email with this same thought.), but I want to echo a piece of feedback I sent to you last year (and the year before I think):

Faster checkout. And improved trust (somehow).

I hear you folks acquired fast.co which seems to be a step in this direction. Entering card details on every site is problematic. Some customers are still worried about it and prefer to use PayPal. Indeed, when I offer both as an option, and make clear Stripe payments go via Stripe and we don't see details, about 80% of people choose to pay with PayPal.

Stripe Checkout, being on your platform and not our sites, seems to be a step in the right direction. I'd also like to see faster payments. My opinion: checkout takes too long. Sites making people create accounts, go through 4 pages and then enter card is bad.

--------

I think, honestly, integrating fast.co into Stripe and making it highly encouraged is the future. Go a step further and encourage sites to stop making users create accounts. SSO-style system, perhaps, but easy to integrate. Authentication is a pain for me as a customer on sites - I have too many accounts and it drains a lot of time combined. I really think your company has the power to make a difference to this problem.
