I'd be surprised if this "community" could gather money for anything remotely useful.

Also: I'd like to see the outcome of a fundraising, and the demographics of the donators, to see how many pledge outside of CA, and outside of the USA. This would give me an impression about the extent of the Trump is Satan and the world is about to end mindset. (imho nothing changes, things proceed with trump as before. business as usual)

Just to make it clear: I'd not give a single penny for it, I care for the health of US citizens only as much as they care for the health of citizens of other countries.

It doesn't matter at all if the water evaporating from your skin is sweat or from the shower, the phase change is what transfers thermal energy from your body. So, cold water will remove slightly more heat warming to the point of evaporation (about 4 joules per gram per degree Celsius difference) but the latent heat of evaporation of water is about 2000 joules per gram, which is much more than the difference between hot and cold water. So it doesn't matter that much whether the water is cold or hot, just that it evaporates off your skin and takes the heat with it.
Great points! I think tiny fraction of those points were meant to be solved with (crisischeckin)[https://github.com/HTBox/crisischeckin] from HTBox, however it doesn't seem to be in active development right now. It seems to me that coordination is key in such situation, I wonder to what level it could be 'automated' by the application so perhaps a human coordinator role can be offloaded as much as possible, so even untrained people can benefit from the app.
Does that mean that the different sites within each group have the same listings and deals as the other sites in the same group?
Of those, only real time energy usage monitoring is really interesting, I think.
Outside/In interviewed some miners and families recently. It's phenomenal radio, actually talking to the people everyone else just talks about.

I don't understand why a backup service would need to setup regional infrastructure. It's not sensitive to latency, the bandwidth costs the same and it adds management overhead.
"Cool" doesn't enter the conversation until you're under 70.

Same. I have trouble sleeping if it's above about 70 or so. My AC went out for a couple of nights about a month ago and it about drove me batshit crazy.

It's funny how perspectives vary though. I was a consultant a few jobs back, and so traveled all around the country for a few years. And early on I made assumptions, like, "all hotels will have AC". And then I get sent to a northern city (I think this was Milwaukee, if memory serves correctly) in winter-time. I get there and it's way too hot in my room for me to fall asleep. I turn the thermostat down and nothing happens. After a while I call the front desk and they're like "Oh, we turn the A/C off this time of year". Uuuuurgggh... they finally had to send maintenance around to undo the window locks so I could crack the window to let some cold air in (thankfully it was freezing ass cold outside, so it didn't take much to cool the room down).

The reason it doesn't have that density is because of NIMBYs and train opponents like yourself. But the tide has already turned, measure S and skyrocketing rents show that everything has changed. I see cranes all over the place, trains will follow.

The solution I think is a little more like what a salon does - a good, shared platform.

I think if somebody wrote a Uber for x planning on the 1 on 1 repeat business, they'd be fine... and how?

1) Provide real value for provider - an easy to use billing platform, scouting out of the upfront work and risk, and classification of the customer and (here's what I think would be the big one) work schedule management.

2)Provide real value for the customer, it be being able to evaluate a provider, get good ratings (and here's the kicker) if the preferred provider isn't available, they don't have to go hunting.

3) Let providers recommend each other. Temper that with user ratings and platform specific ratings. Have users report when a job isn't done right, or another visit needs to be made, etc. But the provider peer ratings are like "I have too much work to provide x, you should try John, I trust his work."

4) The categorization of work could have meaningful use to the providers - it lets providers specialize further than they normally could otherwise, and provide a platform to fall back on.
You're right that this is an oft-misstated reason for avoiding doing so. Layering encryption this way can only decrease security (in a theoretical sense) if the key and/or encryption algorithms aren't independent of one-another. If both are secure algorithms and you use two independent keys, the composition is at least as strong as the strongest of the two.

The real reason is that the risk of a catastrophic AES break is less than the risk of you mis-implementing this feature. As a real world example, take this [bug in OpenSSL](https://marc.info/?l=openbsd-tech&m=144472550016118) that was intended to prevent DES weak keys.

A more theoretical example of a buggy implementation might be actually a very narrow interpretation of the original point. If you reuse the same key between both algorithms (or, generally, using keys that aren't independent of one-another), it's possible for the second cipher to "undo" the work of the first. A trivial example is AES-CTR(k, AES-CTR(k, pt)), which undoes the original encryption. A less-silly but potentially problematic one might be ChaCha20(k, Salsa20(k, pt)). The two algorithms are different, but very similar in design. There's no known issue with combining them in this way, but it would make me extremely nervous to see such a construct in the wild.

So in a sense we've come full circle. As I pointed out, the real reason is that you're more likely to introduce a bug implementing layered encryption than you are to prevent a catastrophic failure of your cipher. But ironically, one of the more likely instances of a buggy implementation is reusing the same key for both ciphers, which is something along the lines of what the grandparent poster indicated.

As a postscript, one other reason is performance. AES is hardware-accelerated, but other algorithms aren't (though ChaCha20 is extraordinarily fast in general-purpose hardware). Layering means a performance penalty, which is a generally minor but still very valid reason to avoid layering.

The Essential Guide to Growing Your Early-Stage SaaS Startup
What's a half month rent 2k? Seems reasonable for a split system. Inc installation.
After watching their promo video at the top of the page, I'm left wondering two things:

- If the machine takes away all my liberty (I cannot use it on my fruit and vegetables) and even their packs need to be refrigerated and stay good only for 8 days, can't I just buy the resulting juice and put it in my fridge? (If I left the bottle closed, that would last equally long). So what do I gain?

- They're using QR codes to check that I'm not using their packs beyond the "best by" date or try to trick the machine into squeezing a competitor's cheaper packs. And for that, they need a camera on the inside. And WiFi. Didn't somebody at some point notice that the way they're treating their customers is really disrespectful? This is the whole printer-cartridge-thing all over again.

Ok? And there's "a lot" of people in wheelchairs who mountainclimb... from the perspective of the 5 people who do.

It's immature word games at best, and insecure egoism at worst, to act this way in the face of overwhelming rhetorical truth. The vast majority of "old" people had zero use for the tech as we know it in their daily lives for most of their lives. As such, most of them have no idea what is going on.

This is common sense, well understood fact.
In terms of languages I'd echo the sibling comment, Ruby or python are likely to be good choices.

If you're looking for things to start getting into security type learning, you could do a lot worse than start with CTFs (https://ctftime.org/ctf-wtf/) Whilst they're not identical to what you'll face as a security tester, they cover a lot of similar skills. Also you'll likely meet people in the industry by doing them.

Unless you are traveling in subway/Uber/Car-pool/commuter-rail and catching a quick nap.

What does this have to do with AI. In fact having an alarm that randomly gets disbabled is Stupid design.
But does the platform necessarily need to profit from every transaction?

Consider a real estate website: They don't get a cut of the monthly rent, they just charge a single fee up front.

The value that these platforms provide is connecting customers with service providers, and this is what should be charged for. The value of the platform goes to zero as soon as the customer/provider know each other.

So here's an idea: maybe the platform should charge only for the first appointment? Sure, revenue per customer is lower, but retention is bigger -- people keep using your service, and next time they need someone on short notice, they will use your website again.

If you run a marketplace, you need to make sure your business model is aligned with your users. If it isn't, you'll fight an uphill battle.
There are of course lots and lots of ways of writing useless tests, but I don't think it's right that the most important part of any software are its features. I for example prefer software with fewer features that works reliably over software that includes everything and the kitchen sink but crashes regularly.
Why is this necessary? I thought Alphabet was meant to eventually achieve this, what makes the extra company necessary?
I agree; I've been working on my mess of a side project for years now. I let the scope grow tremendously, and started over more times than I can remember. It's fun to experiment with potentially better or more interesting ways of doing something in a side project without worrying how much time it "wastes" in the long run.
I'm an introvert as well...plenty are...but I don't think avoiding "unnecessary contact" is really healthy. Introversion is a weakness as I see it honestly...a negative feedback loop of underdeveloped social skills yielding yet more fear, insecurity around social contact. It's not a binary condition like I'm a Leo or a diabetic. Just saying, it's probably better to view as personal challenge than a condition that needs to be accommodated outright.
No. Booked with debit card, not credit card, which as far as I know makes the requirements for chargebacks higher.
You hit the nail on the head, pure research is not a profitable activity. This is why we can't trust companies and corporations to research.. their motives are almost always profit driven. This only underlines the importance of government funded research, and the need to have a government in place who is willing to put the advancement of our society over their own personal gain (We don't have that right now..).

Internet search has evolved past that of a free market entity; search is now a public utility as much as power and water.

You can't imagine a neighborhood without power and water. You can't imagine the internet without search. Google today is like the AT&T of old.

Why is n++ faster than n=n+1?
The aggregators I looked into working with (5+ years ago) required that you offer rate parity. You had to guarantee that for a given room+date+conditions you would give the lowest price to them as you would anywhere else.

The way around it was to offer more flexibility for direct bookings or throw in breakfast.

I may be out of my depth but I disagree. When I see … I read “and so on” so my brain when it sees 0.9… writes a function which first produces 0.9, then 0.99, then 0.999 and keeps going and never stops – it's return type is the bottom type to use type theoretic jargon. I say 'produces' but the function never returns so if there was some way to sample where the function was at or … (heh, that's an ordinary ellipsis). Or rather say it is a function where the first time it returns 0.9, the next time it returns 0.99 at a higher resolution, then 0.999, and so on.

If I'm wrong then I'm wrong for this reason. Mathematicians are using the symbol … ambiguously. Because in some places in math it really does just mean “and so on“ and nothing more. Or more pedantically “and keep going in such a manner following that pattern“.

If, as you say, in instances like this mathematicians take … to mean “the limit (from calculus) of the demonstrated sequence” this is news to me. Well, maybe it's not news to me but I'm not exactly buying it.

What I'm saying is that the expression could be taken to be one of any number of things (not sure if I ought to qualify that with the phrase 'mutually exclusive'): (1) the (symbolic representation of the) sequence, (2) the most recently generated term, (3) the generator (4) the limit (from calculus) of the sequence. That you say the convention is that it most assuredly is 4 is not something I'm buying into. (I'd nearly go a step further and assert that it ought not be defined this way).

Where we get into problems, I believe, is when people say nonsensical things like the sequence reaches 1. Or if they start talking about the actually completed sequence rather than a symbolic representation of it. And this, by the way, is the gripe that people have with Cantor's completed infinities. It really is an ontological claim, not a mathematical one that such things exist. It's a claim whose refutation I support. When this topic comes up on HN I invariably point[0] people towards the absolutely best book I've read on the subject. René Guénon's The Metaphysical Principles of the Infinitesimal Calculus. This book is lucid, compelling, precise. I urge anyone with even the slightest bit of interest in this topic to read it. The notion of the continuum is a very very slippery beast and I know of no other book that deals with the topic so well. Category theorists have a much better handle on the smoothness of the continuum than set theorists because they have far better machinery.
