> For flying jets though (assuming this is what the GP means when mentioning the respect for airline pilots), you'll have some higher numbers, and you'll use the thrust for speed rather than the "counter intuitive" approach you'd use in a smaller aircraft.

Minor point - fairly certain power applications are used regardless of the size of aircraft to control the rate of descent.

Pitch + Power = Performance

You're essentially trying to get back on your landing descent profile.

Too low? Add power, pitch up slightly to maintain speed, reduce rate of descent.
Too high? Remove power, pitch down slightly to maintain speed, increase rate of descent.

It is somewhat counter intuitive, but power does not have a "direct" relation with speed, but certainly impacts it.

Even if you fly straight and level, and start adding power - the increase airflow over the wings/elevators will cause a pitch up / lift, your speed will decrease which will need counteracting by a slight downwards pitch to maintain straight / level, and only then would you see a speed increase. There will always be a point where the aircraft just settles into a given configuration of power and pitch/attitude, giving you a specific horizontal/vertical speed.

You yourself mention pointing the aircraft down (pitch), thus gaining speed (without touching the power), which is exactly the counter-intuitive approach to power/speed.

I may not be explaining it well but here's a decent article:

http://txtopaviation.com/pitch-power-performance/

And you'll find quite a few more if you go searching.

I also highly recommend looking up the pilot owner manuals, they give you performance tables for given configurations (rpm, power, density, altitude, fuel, temp etc), and of course what power settings to use and numbers to hit for various stages of flight.

I do concur with all your other points though, it's an absolute blast - especially in VR. And of course, I can't encourage folks enough to try out the real thing, I find it easier than driving a car! :)

My partner has lived in FF as their browser of choice for over 15 years now.

She is very angry at the lack of user-respectful UX around the change.

* No way to manage the landing page favourites order. An issue in fenix, but no indication of intent to change.

* Default shifted to "speedy read-y down-the-bottom-y"

* Tabs replaced by the counter of pages open.

* It was anything but "principle of least astonishment"

The delivery of better tracking protection? Thats great.

The unexpected UI changes? They suck. No amount of A/B testing can help you in the communication of "this is better" if you don't actually try to communicate.

(This is pop-psych so take it with a grain of salt.) One way it’s been explained to me is that guilt and shame are tools for suppressing action and passion. They’re really good tools to get someone to stop doing something; but terrible tools to get someone to start. To start a new initiative you want to be motivated. But guilt/shame are tools of disengagement. They suppress our capacity for proactive action.

Doesn't AmEx own Diner's Club? If so, their CCV is usually 4 digits instead of 3. So the number becomes the 14 on the front of the card plus the 4 of the CCV for 18 total.
The liability is usually with the card issuer (bank), unless the merchant fails to meet liability shift requirements - like processes a card via the manually entered numbers or magstripe, rather than the chip in the card if the terminal supports it.

This the way card networks have encouraged migration to systems that support tokens and cryptograms to limit fraud.

Strange that systems have limitations like this. I know, there's always design trade offs.

I can testify to a lot of the difficulties Robert Strandh talks about here. We implemented a Common Lisp in C++ that interoperates with C++ (https://github.com/clasp-developers/clasp.git). I ended up implementing a lot more C++ code than I wanted to and then replacing much of it with Common Lisp versions (during startup) because it's easier to maintain and we can use type inference to improve the performance of Common Lisp code while C++ code is 'stuck' with the types you compile it with. Bootstrapping is hard.

I'm pretty sure Mozilla screwed this process deliberately. At the end of the day, their only real source of income is Google paying to be the default search engine.

I think most of the PKI trust issue, at least with regard to financial transactions, could be solved with government involvement. Governments could sign, or issue, PKI keys when they issue identity documents and business licenses. There's much less room for impersonation fraud if the keys used by businesses and people to identify themselves electronically are tied to their foundational identity documents.

Obviously, using government-controlled PKI for communications would be unwise, but there's very little risk to using government PKI for financial transactions as governments already have warrantless access to this data.

Is there evidence that cats are actually a problem for local wildlife in NZ? Which species are under threat?

I've found this belief is common, and it may well be true in some places (including NZ), but it's not true in many, too. In the UK for example there's no evidence to suggest cats are a problem for bird populations[1]. There is a lot of wild extrapolation going on with this subject.

Often I see people quoting statistics such as an absolute number of bird deaths caused by cats, not really understanding that you can't tell from just that statistic whether or not the species are under threat.

What is the text in the agreement that blocks developers from building against it though?

If a third party developer uses an open source library instead of Unreal, must that library belong to an entity that signed an agreement with Apple or the whole app is banned by default?
I’m sure there is a good reason but I never got why nodejs/js doesn’t have channels something like Go https://gobyexample.com/channels

Countless times I have wanted endpoints to send data at certain intervals via ws/http/etc and the have the node app upload them somewhere else in an orderly queue but that doesn’t really seem possible. But with this library or similar you can.

It just seems like a common use case that isn’t implemented natively.

Stop using 6-digit iPhone passcodes
No bank does addressing like that.

Amex for example have got only 6 digits per prefix. 15 digit card number, 6 digit BIN, 7 digit account number, 1 digit representing which card it is (1 for the first, and it gets bumped up with any replacements), and 2 digits for the position on account, allowing you to have 99 supplementary cards on account that can then be identified.

Obviously this is just Amex and it's an absolute non issue for them seeing that they own the entire 37 and 34 range, but I can assure you that virtually no financial institution actually use all of the 9 digits like that.
1930s Household Refrigerators (2013)
It's not relevant. The cut taken is not the point. It's that the app store is the only avenue onto an iOS device. EVERY OTHER meaningful computing platform (that is, not solely a gaming device) has multiple avenues to acquire and install software. Not iOS, and that's the issue.

I don't know why I keep expecting users here to understand this. It's not going to happen.

How to Develop a Sense of Direction
I spent a full winter sleeping on a second story screened porch (it was a private porch off my very small bedroom and I figured that since I didn't mind sleeping in the cold, I might as well save the floor space in my bedroom and move the bed to the porch).

On the very coldest nights I would get out my 10˚F mummy bag, and use a couple blankets on top of that, but I was never uncomfortable, even well below zero (Fahrenheit).

Getting _out_ of bed was pretty miserable at times, but it was only a few steps to the door into the house.

I am glad that gender dynamics is finally being explored by mainstream readers. Men seem to have the onus on them to try and understand courting women-- What women look for, how to please them. The reverse does not seem to be true, at least in my experience.

Women don't seem interested in figuring out how to court men's commitment (probably because they assume they don't have to). Unfortunately for women though, it seems men are less and less interested in marriage these days. Probably due to the unbalanced legally binding financial consequences for men, despite supposed "equality".

Perhaps we'll see a redistribution of interest on the part of women, in trying to develop themselves into desirable partners, the way men are forced to. For example, men have to obtain resources and use the resources to purchase status signals. In the future, if the trend continues, women may have to demonstrate wifely & motherly skills in order to attract the top echelon men they want.

It's been a few weeks since I listened to the podcast, but I thought Dance explicitly mentioned how sad it was for Facebook to get a bad rep for releasing those numbers when such transparency is a positive thing. It shows that they're at least trying to get it off their platform. And if more people knew the numbers, this issue would finally become too large of an elephant to ignore.

And he did offer one concrete solution: platforms with easy discoverability (in other words, easy to masquerade as and target teens) may not need end-to-end encryption. Let FB and such run their algorithms on those messages. And it may be safe to assume three letter agencies are listening in. End-to-end encryption still serves its purpose for whistleblowing, privacy, and fair democracy; it'll just be found elsewhere, like Signal and such.

This still isn't an ideal solution. I personally think it's an unwinnable battle. Easily duplicated instantaneous secure multimedia communication is ridiculously revolutionary.

Show HN: Routine Ops – A Human Orchestration System
Link: https://routineops.com

Hi HN,

My name is Chris and for the last few months I've been building Routine Ops. I posted here in Show HN about a month ago to get some early feedback, but the product was still largely unfinished. Even so, the response and feedback was great so I went back to work on improving the UI.

Super excited with the progress I've been able to make on the app over the last month so I'm posting here again to collect as much feedback from the community as possible.

What's changed?

- Almost every page in the UI has been completely overhauled to minimize the need for clicking around.

- Add your team! When I "launched" before you couldn't add your teammates yet. Now you can invite your team to join your organization.

- Pricing model - Initially the app was free for individuals. Now, it's free for teams up to 5 people and paid after that. In the future, there will also be features enabled on the paid plan that aren't on the free plan.

What's next?

It's a super simple concept right now - assign recurring tasks to roles on your team. What will it take to be a real "Human Orchestration System"?

- Goal tracking - set and track progress toward goals with regularly scheduled check-ins

- Basic Calendar integration - add all your recurring tasks in Routine Ops to your Outlook/Google Calendar

- Smart Calendar integration - sync with your calendar and suggest tasks to do during open windows in your day

- SMS Integration - if you haven't completed a task by it's due date, you will receive a text asking "Did you complete this task?" and you can reply "Yes" or "No" to complete the task.

These are just a few ideas of what I want to develop next. What do you guys think a Human Orchestration System would/should look like?
I wouldn't call that a contradiction or clarification. It's yet another confound and there's no reason to believe it cancels out the other ones.

In this case, people arriving sicker at the hospital with a given disease is not necessarily an indication of the likelihood of death with no treatment. For instance, robust young people may wait until they are extremely sick before heading to the hospital, while old or immunocompromised people may go at the first sign of illness. In that case, you would expect death rate to be negatively correlated with how sick people are when they arrive at the hospital.

I was fortunate enough to watch the Zoom of the hearing - the Apple lawyer claimed that in cases of breach, it is normal for Apple to disable all related developer accounts to limit the offender's ability to 'hide' behind alternate accounts.

In this case, the two accounts in question (the one for Fortnite and the one for Unreal engine), while on paper are separate entities, were paid for by the same person, using the same credit card number - so that was Apple's justification for removing both.

As the order shows, the judge still felt it was overreach.

In my (limited) powershell experience, it's a "scripting first" shell, while bash is more of a a cli-first shell.

Using a powershell cli is very verbose (although pretty consistent), but using it without some sort of GUI helper if you're not familiar with it is pretty daunting.
I'd love to believe it. It sounds plausible. I'd have to see a lot more to invest in it.
Elected governments lose that ability when they hide what they are doing from their voters. Then they just become ordinary hierarchs.

Also, the NSA and CIA are act unconstitutionally and then hide the fact they are doing so from the voters. A fairer way to see if there is actually public support would be to allow a group of 100 people into the CIA/NSA archives and allow them full access to the entirety of the uncensored information, without anyone to justify what they have done beyond what has been recorded.

Otherwise, polling people on what unaccountable agencies do illegally in secret is (figuratively) like asking a North Korean if Kim Jong Un is doing a good job. They just don't have the information to judge.
One big difference, I imagine, is the population that forest is being extracted for. The Amazon isn't only being extracted while sustaining 100s of millions of South Americans (prior to colonization AUS had fewer than a million inhabitants), but also serving the world's demands. So I think it's different although in balance both unsustainably.
It does not have to be perfect, just better than existing payment card numbers, for that specific use case anyway.

I was in a role to take customer calls for years, and did straight up support for a while early in my career. I found that if I took a genuine interest in their problems, and an interest in the individual, it turned a lot of bad attitudes around. Someone calls and is angry, frustrated with the thing we’ve made, it was my job to help them, not just fix the issue but feel happy with the product, too. That being said, there’s no helping some people, and some products may be too bad to rightfully support.
"In fact, most data science and ML engineers are quite skilled in systems engineering, because you have to do so much work with GPU hardware issues, underlying scientific package management, efficient data transportation, etc."

This does not align with my experience working with many data/applied scientists at very large companies. A lot of them cannot even write basic code or use git commands. The engineers who are capable are often silo'd away from the scientists, and the organizations struggle to produce any real value.
