My internal pedant compels me to note that a turbine-based engine (which all aviation jet engines are, AFAIK) is still an internal-combustion-engine. Not all internal combustion designs rely on reciprocating pistons. Though you are quite correct that turbine-based designs can achieve efficiencies that most piston-based designs typically can't.

I was thinking in terms of passenger cars for some reason (despite the word "airplane" being in the title), where piston engines are far more common than turbine engines. That said, I stand by the main point of my post, which is that you can't just consider the energy density of your energy source in isolation, you have to also account for the efficiency by which you convert that energy source to useful work.

A thing I find myself wondering about now is the viability of an arrangement similar to that of cargo trains. IIRC, the locomotive of cargo trains is a hybrid of sorts. An internal combustion engine running at relatively high efficiency drives a generator, which in turn powers electric motors which drive the wheels. This sound similar to your hybrid idea, perhaps with the addition of batteries.

I think one of the biggest challenges to hybrid systems is to make sure the overall system efficiency doesn't drop below that of the current typical systems which it is intended to replace. Say you have a plane with turbojet engines running at 60% efficiency. And we replace it with a charging turbine-engine at 70% efficiency, coupled to an 80%-efficient charging system, coupled to a 90%-efficient electrical engine. In isolation, each of those numbers sound better than the 60% efficiency of the turbojet engine. However, efficiencies combine multiplicatively, and so 70% * 80% * 90% = 50.4%. That's overall worse than the turbojet we started with. This new system better be much lighter than a turbojet to be worth it.

Note that this is just in the absence of a prenuptial agreement that states a different allocation.

I've never been married, nor helped any married person apply for any kind of loan or credit, so have no idea what extra information is asked for if you check the "married" box instead of the "single" box on an application. Do the financial institutions ask married people about any prenups they are under?
What do you mean war? Are you suggesting that the IRS should target people who "don't deserve or qualify for the credit"?

Maybe just let people claim it who shouldn't be getting it?
I think their point was that architectural decisions shouldn't be dictated by any one single engineer.
As far as I know, floating point add and multiply are commutative (but not associative) in IEEE 754. And I believe C and C++ allow you to detect if IEEE 754 is used by the hardware and if so, execute the floating point expressions as written.

Note: That is of course no longer true under -ffast-math.
what about using something like proxycrawl? will that help in anything? They say it's safe
I've gone from loving Flow state early in my career, to being cautious about it, to watching with suspicion and dread the behavior of my coworkers to see if they are making decisions based on opportunities to engage in it instead of rational thought. For some it seems like a form of thrill seeking.

When you are in flow state you are producing a lot of output but aren't asking any questions. That turns into big, solid chunks of the system with no oversight, no consensus, no introspection, no empathy. And when someone does ask questions - because who wouldn't? - we aren't questioning a small isolated part of the architecture, we're questioning a very big piece. One that the author feels very warm feelings about because they had An Experience while writing it.

Flow state is useful, possibly great for refactoring. It's occasionally a waking nightmare for new code, and not a great experience for everyone else the rest of the time.
With pipx when you install things they go into isolated environments. With pip you're just installing things globally.

This difference is important due to dependencies- if you have two different CLI tools you want to install but they have conflicting dependencies then pip is going to put at least one of them into an unusable state, while pipx will allow them to both coexist on the same system.
I wonder if you might have had a bad experience with the old rules-based PageSpeed Insights? It wasn't as good as the current one, being more of a checklist of "have you done all these things that usually help" and not "we loaded the page, computed metrics, and this is how well it did".
HN is a large enough sample that I don't think it's so different from humans in general, including internet humans in general. If that's right, then the differences you're talking about are mostly contextual.

In this context, we do much better by practicing the guidelines in relation to everyone, even article authors. The point is not that we owe them that, but that we owe ourselves that, because it's how we can maintain our community together.
that depends on your luck to be honest, although I think it's not true in any way but you can always think like that and you will have a better life
Your quote misses the most important part:

>>"Covered entities may disclose protected health information to an entity in its role as a business associate only to help the covered entity carry out its health care functions – not for the business associate’s independent use or purposes, except as needed for the proper management and administration of the business associate."

BAA's keep the chain of HIPAA in place but just because a BAA is in place does not allow for violation of privacy.
Ideally, everything related to sessions and domains. The security model we operate under on the web is completely outdated, which adds a ton of complexity to everything else.

Secondly, I would look into cutting out all the parts of the HTTP protocol normal websites aren't commonly using to reduce the complexity of the implementations.

A lot of things HTTP does are probably better off being move to other protocols altogether.
Being in the data science community myself, I prefer straight venv + pip to conda. It’s simpler for me to manage errors. I only use conda when I have to.

Somewhat surprising fact about most PostgreSQL deployments is that most of the frequently accessed tuples will fit into RAM and it handles this usecase really well (to the extent that people who don’t know any better do not see any issue with LIKE ‘%whatewer%’ over 100M tuple table, it just takes 1.5s, so what...)

> but there's absolutely no reason to actually believe they're conditioning on gender.

The anecdotal evidence, that many women are claiming that they received much lower credit limits than their partners, despite similar or superior credit conditions, would seem to indicate otherwise.

I don't believe anyone is saying that they're directly doing it. Just that their algorithms have that outcome.
I meant if it costs the same as a restaurant, it's not cheaper and thus I wouldn't call it street food. I wasn't comparing across cities. If a decent restaurant decides to ditch their downtown indoor restaurant, and decide to get a food cart and offer the same food for the same price as they did, is it really street food?

A number of popular food carts in Portland have a median price of $10 or above. For things like Mediterranean food I've often found restaurants charging the same or less. At the end of the day, I'm paying for the privilege of standing in the cold/rain.

Code reviews help gate this behavior, a bit. If a coworker does this and drops a 40k line PR, they get code review duty for everybody else for a little while _before_ their code can get merged. Letting them go unfettered definitely is a mistake.
Data being used for services is inevitable, but at this point we really need two things.
1 - Laws around how shared data can be used that are more comprehensive
2 - A secure database either managed by private companies or the government (with strong oversight) that allows companies who want to use the data to access it but not store it. The key is that the companies using the data and the companies storing the data cannot be controlled or owned by the same entity.

The companies who store the data also cannot be allowed to make money based on the type of data. They would need to be limited to only monetizing the cost of distributing the data.
There will also be need to police that companies do not store the data they have access to.

Hey All! A little back story here... I've always hated shopping and then some friends (and my wife) encouraged me to do a capsule closet.

It's been working really well! I have fewer clothing decisions than ever and look good!

So I wanted to make a list of sites that make this approach possible. Feel free to add PRs. I would love that!
Criminals talking about their crimes really shouldn't blow your mind. It's very common for criminals to get caught because they couldn't keep their mouth shut. Murderers get caught like this all the time, and murder is much more serious than money laundering.

Maybe you’re missing my point? Just saying you don’t have a choice doesn’t make it so.

You do have a choice: go to the bank, pay your bills by mail, call a company on the phone, etc. AFAIK none of those things are examples of leaving society. You may not like that choice, but don’t pretend it doesn’t exist.

You’re acting like your hand is somehow forced by something you find objectionable when alternatives do exist.
I’d appreciate if DuckDuckGo would implement this kind of speed badge to their search results. Never going to assume Google would even consider it as they sell the things that make sites slow in the first place.
How do you figure?

You agreed that your posts would be moderated when you signed up. Should Facebook be eternally available to host people's timeline? Who pays for that? Why should I innovate the next big thing if someone in a different country is going to hold me legally responsible to support it forever?

And the ruling doesn't mean Twitter has to host Trump's Tweets forever or guarantee service. If he breaks their TOS they will ban him. They have a right too.

What the ruling means is that the government has a responsibility to archive his Twitter posts and that he himself cannot restrict access to it, as president.
You can get this with standard pip by setting the PIP_REQUIRE_VIRTUALENV env variable.
And anyway, you should tell people to install mini conda, not conda, unless they know they'll need everything it includes by default.
What about a dedicated high-performance audio/DSP langauge like csound?
Curious to hear other's experiences with pipenv vs poetry. Has anyone made the switch?
I've not used Prompt Toolkit (or usql) but am very interested in making better cli, what makes Prompt Toolkit so good?
This article is great, those are viable solutions for sure. One of the alternatives is conda: it's common among data scientists, but many of its features (isolation between environments, you can keep private repository off the internet) meet enterprise needs.
The IRS cannot charge a 30% interest rate. They charge short term plus 300bps. There's some other fees, but they cap out too.
The amount of memory needed to hold an integer is log(N). That's just because the log is about how many digits it has. That fact doesn't depend on the hardware, it's just a math fact.
I've worked with too many engineers who got a lot done by making it hard for anyone else to get things done. I think there aren't very many 10x engineers but there are a lot of 4x engineers who make everyone else .4x engineers.

I was a lot happier and less busy trying to be a 3x engineer making everyone else into 1.5x engineers.

Why "instead"?

The IRS has identified that certain refundable credits (EITC) have a very high error rate (25-30%). As I understand it, it has created a mostly-automated mechanism to identify the filing errors that lead to these issues.

Should the IRS not be doing that because it lacks the resources to perform audits which are less subject to automation? Or should it not be doing that because EITC is only paid to lower-income households?

Some fraction of the incorrect EITC filings are undoubtedly fraudulent. What, in your view, is the acceptable rate of potential fraud that the IRS should detect, but ignore, based on income level?

Personality type has a big role to play here. Certain personality types can't become workaholics.

Let them go find their own path, and while they do that, some tolerance for whatever work-in-progress philosophy they might spout, is not a bad thing.

Nobel winner Richard Thaler -

"I would never deny being lazy, but did Danny(Daniel Kahneman) thinks that my laziness was my single best quality? To this day, Danny insists it is. My laziness, he claims, means I only work on questions that are intriguing enough to overcome this default tendency of avoiding work.'

"thriving and survival in an unstable future" doesn't mean following just one route. Nature shows us there are a whole bunch of routes. From the cactii to the banyan tree you can find value in all of them or what best suits you.
Circular homes minimize the required material and the surface through which heat is lost or gained.

In normal places, there is no need to think about maximizing the land usage. People typically put a 2000 square foot house on a 10000 square foot lot. For a circular home on a square lot, that is 51 feet in diameter on a 100x100 lot. Each side has more than 24 feet to spare.

We really don't care too much about minimizing lot size. In most places, it isn't even legal to have a tiny lot. The excess can be trees or whatever, and most of us like it that way.
It’s like we need some sort of indicator or progress visualization. Something that will show the user were the page is in terms of loading and rendering.

I haven't used pipx, but as far as I understand, pipx = pip + venv.
If your pip executable is in a virtualenv, the "globally installed" is locally installed.

pipx, poetry, pipenv and co are still nice wrappers to have, I suppose. It just feel less useful now that most of my projects are dockerized.

> Why disable one critical crew member needed for a submarine's launch, when you can kill him, the entire crew, and everyone in a 10-mile radius with a single nuclear warhead?

Because you don't have enough of them...

You can't win against a nuclear state with 100+ ICBMs unless you strike first, or do a beheading strike.

USSR had really no defensive plan, as was found after the fall. They really bet all on "firing all your guns, before enemy can destroy them"
Yeah, I get where you're coming from. There's as always a sweet spot between the two extremes. But needing a new computer for running Word or Excel smoothly just seems like there's a lot of low hanging fruit left.
And if the computer needs to ask the person a bunch of clarifying questions because they're providing ambiguous instructions, do we really trust that person's judgement about handling the unanticipated edge cases?
hard work by definition is hard on the person performing it. When there’s no return on it, it’s just being hard on oneself for no benefit.

creating the habit to assess the benefits is more important than blindly working hard. Otherwise it’s just getting sick, exhausted, and having no life for no rational reason.
Look at the www.monolithic.com floor plans. Because the domes are large, typical rooms will have 2 or 3 straight walls. It's only the exterior wall that is curved.
This is where mandatory code reviews really help. He can't merge that crap and mess everyone else up without someone approving the changes.

Also, to be frank, if his code is reverberating all over the code base like that, causing merge conflicts and re-write all over the place, he is a terrible engineer - not a brilliant engineer. He clearly had no knowledge of the basic SOLID principles, modularization, encapsulation, etc. He was a rookie blasting experiments all over the code base.
RF and the Atmosphere being what they are and the non-variable parts of this equation mean there are significant real physical and abstract legal limits for any project attempting to put "bandwidth in orbit."
Yet another reason to avoid it entirely.
Could low temperatures especially at higher altitudes be a problem? Aircraft probably get exposed to higher temperature gradients and in much shorter periods of time than a typical Tesla would encounter. Not sure about Lithium Sulfur batteries but reduced capacity at lower temperatures is common for many battery types.
DoD RFI for Non-Medical SynBio Focus Areas Ready for Manufacture
Don't feel bad. Someone from college bought my QuietComfort 15 pretty cheap when I got the 35. I found it odd that he'd buy it as it's pricey there (Brazil), and tried to convince him not to (as he wasn't rich or even working regularly). He told me not to worry and asked to pay in installments. I made the mistake of accepting his offer, and he practically vanished after paying about 50 USD for it (I sold it for about 130 USD). I am someone who he could ask a referral. Instead, now he has a recommendation against him.
Looks like a mistake on my part, I was probably playing around with another parameter and forgot to remove it completely. It runs fine with it there so I never noticed it but it isn't needed.
I switched from pipenv to poetry over 1 year ago. I love it!

The main reasoning was so that I could easily build and publish packages to a private repository and then easily import packages from both pypi and the private repository.

Happy to answer more questions.
Hi whalesalad, good to meet you! Now that you know me, you can never say that again anymore :-) Although, tbf, I only use conda for my machine learning related projects. I've tried using pip for that but was at risk of massive hair loss.
“I think that horror following technology in its development is a dead end. We had horror films about TV, now there are films about the web, but in fifty years only scholars of culture will look at them. Meanwhile, people who want to be scared will still watch the scene from Mulholland Drive with the bum peeking around the corner. But that scene could equally be filmed in 1930 or 2030.” (Alexey Karaulov)
In the United States, the role of a central bank is to manage two measures: inflation and unemployment.

The US Federal Reserve Bank does not measure inflation or unemployment. Rather, the US Department of Labour, an independent organisation (and a branch of government rather than a freestanding entity) computes both measures.

This is the principle of division of responsibility and measurement or judgement. You cut, I choose.

Google are both measuring, and rewarding, website performance, as well as designing and distributing the principle tools that benefit by both choices. That's an extreme locus of power. And, history shows, generally a Bad Idea which Ends Poorly.
Part of the problem is that they place high importance on the first contentful paint (aka FCP) above all else. They're not very much looking at how it performs overall, mostly just how long it takes for a user to see the first bit of content. If that were a bit of text that said "loading" with a spinner that goes for a minute or two, they may consider that fast.

Save your gratitude. There are many platforms that let you do that. The only thing special about Facebook is that they are the most popular - and they got most popular by muscling out those other platforms. If it wasn't them, someone else would take their place.

You're not thanking Apple, Samsung, LG, Nokia, etc., for making the phones with which those videos are captured, are you? Why not? If only one of them were left, after having killed its competition with underhanded means, would you then be grateful to them?

Those who watched Twin Peaks: The Return might recognize the connection between the 8th episode and the frog moths.
The second person plural was already used as "the same thing happened to us" so using "we" there would ambiguous and confusing. That is, saying "we should share responsibility" would imply that Wozniak and his wife should sharew responsibility.

I also believe "they" refers to legal responsibilities of the company as a whole, which are distinct and independent from the responsibilities of individual members. See https://en.wikipedia.org/wiki/Corporate_personhood .

Even if you don't like corporate personhood, "they" can also refer to those people with an executive role, that is, the people who collectively made the decision. He does not have executive authority in this decision, so is not a member of that "we".

Why is "we" specifically meaning employment? Can't being a shareholder also count as "we"? That is, I can own a company, and control a company, but not be employed by the company - surely "we" still applies there.

Consider that, if Wozniak own shares of Goldman Sachs then, as shareholder, he could have a role in guiding its policies. (Ditto for Apple, of course.) But it wouldn't make sense to refer to both roles as "we", as that would make it even more confusing.
They do if the plan is self funded. If it’s not, they still get anonymized usage reports from the carrier that list all the claims with basic demographic info like gender, age range and whether it was the employee, child or spouse who the claim was for.
