Do you like beer? Do you remember how gross it was the first time you had it? Black coffee is much the same. I would recommend buying an aero press and a grinder and start making good coffee. Coffee sitting in a pot all day is horrible. Find the best coffee shop around you and try some French press. It takes a few weeks to get over the flavor of black coffee but I can’t imagine drinking coffee with sugar in it anymore.

"The Lancasters attacking Valentin each carried a single large earthquake bomb – seven carried the 5 ton 'Tallboy', thirteen carried the 10 ton 'Grand Slam'. Two 'Grand Slam's hit the target and penetrated about half-way through the 15-foot (4.6 m) thick ferrous concrete roof before exploding. The explosions blew large holes in the remaining thickness of the roof and brought down around 1,000 tons of debris into the chamber below.[8] Workers who were inside the bunker at the time survived, as the bombs did not penetrate the roof before detonating.[8]"

I agree, despite the other comments, the math doesn't work out here.

Yes, the statement is about kidneys. It is only about kidneys, though, and includes all of the information.

No, it has nothing to do with breathing or any other method of eliminating water. The statement says that kidneys max out at 1.0 liters per hour, and 28 liters per day. One of those 2 is obviously wrong, unless we aren't talking about Earth.
> I didn't talk about the whole nozzle. The first line of my post:

> "A rocket engine nozzle produces thrust only for the part where the pressure is greater than atmospheric pressure"

> Then you went on to talk how I'm wrong and talked about the chamber and the nozzle exit area etc. All irrelevant.

Your statement is just plain incorrect (or being charitable, misleading) as written. When the velocity of the exhaust flow is > 0, even if the pressure in some section of the nozzle is below ambient, the nozzle (including the section below ambient pressure) is accelerating the flow, so every element of the nozzle's net contribution to thrust is always > 0.

At the end, I think you are talking about overexpansion losses, but short of pathological cases, in a rocket engine the overexpansion losses will not outweigh the rate of momentum change term.

Edit: To add further, the overexpanded nozzle is producing less thrust than the ideally expanded nozzle. But the overexpanded section is still producing positive thrust, it's just less than what you would have if the nozzle had ended earlier. It's not like that section has reversed sign in terms of thrust production.
That's the old join syntax before ANSI SQL was designed. Except your operators look like "* =" and "= *" (without whitespace of course, blame HN's markdown parser). Sybase supported this syntax well into its version 15.x (maybe still in version 16?). And Sybase did not (does not?) support full outer joins.

It may seem simple on the surface, but once you get into complex queries, it's a horrible syntax, and it's easy to forget the relations between the tables, particularly with several tables (4+) involved.

As someone who has converted an old and large SQL code base from non-ANSI JOINs to ANSI JOINs, I am happy to see this style of syntax abandoned.
Saturn V suffered several engine failures. It had persistent pogo oscillations that put Apollo 6 into the wrong orbit and forced much of its test plan to be canceled, and nearly destroyed Apollo 13 during launch. Vibrations severely damaged Skylab during its launch. I would not say it never failed. It never went kaboom in the sky, but there are other ways to fail.
Even after the war they couldn't demolish it by blasting because even targeted explosions would have been enough to seriously harm everything around it.

"Because it seemed impossible to destroy Valentin by bombing it, the decision was made to destroy it by blasting. This idea was later abandoned because the blasting would have caused severe damage to the nearby villages of Rekum and Farge including the power-station in Farge. In 1960 the bunker was taken over by the German Navy, for use as a storage depot. "[1]

I fear this may end up being the end of full Youtube access for Europeans. Youtube must either have a license with all possible rights holders, which is everybody, or content uploaded by Europeans must be checked by impossible filters, and I suppose content uploaded from elsewhere must be checked by those same filters before it can be shown to Europeans. So basically we're only going to get corporate content from Youtube.

A small consolation is that it may also kill Facebook in the EU, giving more room for smaller, open source, distributed social networks like Diaspora, Mastodon and Friendica. If it's true that this only holds for profit-driven sites, as someone claimed in an earlier discussion about this.

Actually I've been in this business for 5 years and worked in both agencies and content companies, so I have more insider knowledge rather than experience as a customer, hope it's ok.

Most agencies are just hiring freelancers and putting a 10x markup on it. Since they're probably using multiple freelancers per customer, they can't guarantee consistency, which is why they need internal reviewers (which adds to their overhead).

The strategy part is not a lot of work, and I've seen the people that do it working with up to 50 customers simultaneously, so it's not as if it takes a lot of time. 75% of the secret sauce is just picking words out of SemRush. I'm not even joking.

The best ROI right now, IMO:

1. Have one or two good freelancers you trust. You'll have more consistency in your texts and you won't have to manage much. Most freelancers already know how to do the SEO part, because agencies already hire them to do it. They're cheap, so it is easy to "test" them before committing. Good freelancers are low-maintenance.

2. Outsource the strategy to a freelancer. This way you won't be tied to an expensive contract with heavy fines and they'll be able to spend more time. Sometimes they'll also produce content, other times they'll be able to manage other freelancers for you.

3. In my experience, most agencies use run regular consumer tools behind the scenes: Buffer, Semrush, Moz, Mailchimp, Hubspot, and A LOT of Google Docs. SEO checking is done using Yoast, which is free. Most of those tools are simple to use.

It seems pretty clear that this person is definitely not Satoshi Nakamoto. Truth is, I don't really care who it is but it IS super easy to proof that you are. This person didn't prove anything, didn't even try to proof that what he is saying is real.

It seems more likely than what he's trying to do is pump his BCH SV coin.

There are easy ways to prove that someone is Satoshi Nakamoto and unless I see one, anyone claiming they are without providing proof is just a liar.

For instance, CZ, the CEO of Binance said the following :

"The real Satoshi can digitally sign any message to prove it. This is as simple as breathing for him/her. And we have the pub key.

Until then, everyone is Satoshi, except Craig Wright!"

Indeed, a faster way to check if a table does _not_ have a comparable row is a LEFT JOIN with a WHERE NULL clause:

SELECT t1.* FROM t1 LEFT JOIN t2 ON t2.id = t1.foreign_id WHERE t2.id IS NULL

Is a lot faster than the naïve alternative:

SELECT t1.* FROM t1 WHERE NOT EXISTS (SELECT * FROM t2 WHERE id = t1.foreign_id)

Because if your chosen career is an academic that's what you do. You research, write and publish. You could probably make more money by selling your ideas in private industry but that's an entire career pivot, it's like a junkyard becoming a cheap used car lot. It's a lot of work and comes with risk. If you're tenured or close to it you should probably just publish. Sure you could try and sell your ideas on the side but that's not going to endear you to other people in academia.

"News" has always been heavily editorialized from the start.

"Fake news" is just propaganda presented as "news."
Indeed, Sybase for instance treats a single space (e.g. ' ') the same as an empty string (e.g. ''). For the purpose of concatenating in Sybase, NULL is '' (and thus ' '). So `SELECT a = "a" + NULL` would yield a = "a". But so would `SELECT a = "a" + " "`.

MSSQL allows this behaviour, since it's based on Sybase, but you have to explicitly turn it on.

To the contrary, you can view the free market as a parallel system of checks and balances where the people have voice and opinion: your wallet. Yes you can actually "vote" with your wallet in a free market.

And unfortunately unlike the free market, where greed of money actually acts as a balancing factor, greed of power is terrible in a democracy, and we have seen the power grabs of our court systems in not only this current regime, but previous ones controlled by democrats as well. Why is the court system so important? Why are senators willing to risk shutting down the government and achieving actually nothing meaningful session after session? Because there is absolute power there. And there is absolute power now in our imperial presidency, started by Bush, continued on by Obama, and now the loaded gun was left for Trump. If we restore power back to congress like the founders intended (and further restore power back to the people by eliminating political gerrymandering) we may return to the situation you describe, but I'll take free markets over the current broken system we have today.

Yes, there is such a provision and it's been enforced at least once:

https://en.wikipedia.org/wiki/Online_Policy_Group_v._Diebold....

The penalty wasn't big enough to have much of an impact on anyone involved, after lawyer fees. But damages were awarded.

EFF's legal director is quoted in that Wikipedia article discussing that case, so I presume EFF has either a legal or a strategic/PR/financial reason why they can't use that provision in this case.

I'm not a lawyer myself, though I have attended a year or so of law school and I have read the text of the DMCA.
