Airframes equipped to use LH2 will, wherever deployed, lock out competitors without, because the lower takeoff fuel weight allows for more paying cargo instead, and because hydrogen electrolysed right there at the airport should be cheaper per joule than petroleum mined, transported, refined, and transported again.

But inboard LH2 tanks seem to present a safety hazard, wings have not enough room. That seems to leave underslung nacelles. None of the concept designs illustrated have them.

> Most people tolerate them out of sheer politeness

You are projecting. Some people are flattered to be a trusted confidante or emotional support, and glad to be able to help someone they care about. This is situational and dependent on factors (if someone's emotionally leaning on me every second of every day, it's going to get tiring pretty quickly), but even if the experience of the conversation _itself_ isn't exactly pleasant it might still be considered a worthwhile discomfort to go through for the emotional closeness generated (as a parallel - physically exercising isn't (often) pleasant, but the sensation afterwards and the physical well-being generated are considered worthwhile, so the activity is net-desirable even if it's unpleasant in-the-moment). In fact, apologizing for the act might insult the listener, implying that your relationship isn't strong enough to warrant such sharing. Further, the listener might care about the speaker's mood and state of mind so much that, even if the experience is net-negative _for them_, they're still glad to be able to provide that support to someone they love.

This is all subjective - you and your partner might so dislike being vented to, or feel such negligible positive effects from it, that the calculus ends up negative and an apology _is_ genuinely warranted. But it's not necessarily true for all (or even, I'd guess, most) people. You're right that avoiding imposition is good manners, but it is not necessarily the case that sharing feelings with someone is an imposition on them.

I don't believe it is possible to actually accurately determine this. Even if you could define crimes the same across countries, many crimes go unsolved so you wouldn't know if it is one criminal or multiple criminals committing crimes. That was my point. The claim was that incarnation of criminals does not lower crime. I am saying we don't know if that is the case.

"This seems like a weird thing to highlight, to me."

Classic NASA. Read Gene Kranz's "Failure is not an option".

In rocketry you're usually up against physical limits. You need materials near the limits of physical strength and temperature resistance. You need fuels near the limits of energy density. And still you're launching with a payload to destination that's maybe 5% of the mass, if you're lucky. Which is why rocketry has to obsess on weight reduction.

If fuels were 2x as powerful, or gravity was 1/2 as much, this would be easy. A spacecraft would have the weight budget and safety margins of an airliner.

If earth's gravity were somewhat greater, you'd never make it to orbit with chemical fuels.

This is the tyranny of the rocket equation.

each music company supplies both data (track and product metadata, territorial rights, pricing, etc.) and media to the service provider (e.g. Spotify). The process is to sign the contract with the music company, then the company ships all of the data to the provider to ingest into their systems. In the beginning, each music company sent metadata in a different format.. before electronic distribution, they would send hard drives that contained the media and metadata. The distribution formats are now driven by a standards-body.. but iTunes still has its own format.
I think it’s too subtle to be a practical difference: the circumstances are wether it’s _suspected_ to be related to a crime. That’s a low enough bar to be almost non-existent.

https://www.legifrance.gouv.fr/loda/article_lc/LEGIARTI00003...

Then you get additional fines if your refusal can be seen as preventing current crime from being dealt with, or helping further crimes. Which also comes down to perception.

All in all this law is extremely police friendly.

Looks like it simply makes Markdown easier for both computers and humans! I love this and can’t believe I haven’t seen it before.

> Requiring quirky behavior and blank lines that hurt reading

Really? The linked spec says, referring to a blank link in indented lists:

> reStructuredText makes the same design decision.

And as a design goal:

> your document [must be] readable just as it is, without conversion to HTML and without special editor modes that soft-wrap long lines. Remember that source readability was one of the prime goals of Markdown and Commonmark…

Or this, which made me celebrate:

> anything that is indented beyond the start of the list marker belongs in the list item.

In Markdown it’s really hard (aka impossible) to get sections to respect the indentation level they belong to. What a simple rule here: inside a list, items belong to their list item. Beautiful!

Other great quotes:

> we don't need two different styles of headings or code blocks.

> avoid using doubled characters for strong emphasis. Instead… use _ for emphasis and * for strong emphasis

> code span parsing does not backtrack. So if you open a code span and don't close it, it extends to the end of the paragraph

Sanity. Sanity introduced to an ambiguous spec. It’s wonderful.

This bit made me a little unsure:

> although we want to provide the flexibility to include raw content in any output format, there is no reason to privilege HTML. For similar reasons we do not interpret HTML entities, as commonmark does

While Markdown was meant to transform to HTML, I wish it was a spec renderable without a HTML or web browser layer. So I like this. Equally though one use case I personally have is Markdown to static HTML and it’s useful having HTML tags present and handled. So my understanding of this part of the spec is confused (what does “interpret” mean?) but if it means no support for inline HTML that is indeed a pity.
The issue isn’t the bank angle but pitch acceleration felt by the passengers when they pilot wants to bank for a turn. Which opens up several methods to compensate.

You could for example more slowly enter a higher bank angle to have an equally fast turn though passengers would feel more pressed into their seats etc.

Turbulence causing roll upsets seems like it could be a larger issue.

The article is unfortunately an example of numerical illiteracy. The Tufts sites said, in general, fruits veggies legumes and seafood were healthier than all other categories. Within each category, they then ranked food from 1 to 100. Tufts did not say the healthiest grain (still bad for you) was better than steak. That is an incorrect reading.
I tried Arch for a while, and having to go use AUR stuff for things that were a lot easier or built-in in Ubuntu or Fedora while not being vetted at the same level was one of the big things that caused me to go back to those others.

Spotify and Hulu were mostly funded by the industry. Hulu’s main investors were companies like NBC, that’s how they have all the typical network content. Spotify was also had heavy record label investment.

Once upon a time, HTML was a document format, and there was a dream that these documents would be interconnected with deep meaningful semantics that would be machine readable.

But then HTML became the rendering layer for a universal sandboxed VM, and all that went away.
you can do anything with (flat|text) files, they are after all just an often inefficient binary encoding the same as any other binary blob.

The main thing you can do with them though, is tell yourself that you don't really need a spec or documentation because you can just eyeball the output, and not having to follow a spec makes things feel simple.

>The required reserve amount was reduced to zero at the beginning of the pandemic as a way to increase the velocity of money.

No; again. The Fed moved from a 'scarce reserves' regime for monetary policy to an 'ample reserves' regime; that was announced in 2019. Since the 'ample reserves' approach doesn't depend on bank reserves to implement short-term rate management, there wasn't really a need for an ongoing Fed reserve requirement.

>Bank reserves have obviously dropped year over year since the introduction of this policy, especially as a percentage of M1/M2.

Bank reserves increased hugely from 2019 through the middle of 2021, as you can see from the chart I posted. Although they've dropped somewhat since then, they're still like 75x what they were in say 2007.
No. That’s like saying OS should use AI to try and figure out what buttons are to make them clickable, rather that developers actually building an interface for users.

All operating systems and platforms have pretty fluent and in-depth APIs for exposing an “accessibility tree” for assistive technologies to use. It’s your responsibility as a developer to build interfaces for actual users, and there’s very little reason not to.
Hello everyone! We're team ghost and we are so excited to launch version 3.4 of our application! We would love to hear your feedback so please check it out!

Ghost is an AWS Lambda metrics monitoring tool designed to improve upon tools seen before us. Our goal is to seamlessly transition into your daily monitoring routine without the need to shred through documentation or tutorials just to learn the UI. Some of our core features include:
metrics such as throttles and concurrent executions display with instant refresh
ability to create custom graphs with a UI
newly formatted and easy viewing of the user’s available permissions
complementary adjustable pricing calculator to estimate current and future costs
transparent past billing information

Why use us rather than other Lambda metric monitoring tools despite our new features? Transparency is key at ghost, and we want to help you understand your data for free. Rather than paying just to get information that you can get for free or should get for free, our mission is to aid you in conveniently accessing and manipulating your data freely (pun intended).

Check us out at https://os-ghost.github.io/website/ to let our application and mission speak for itself. Before you know it, ghost will integrate in your monitoring life and you won’t even see us coming. Also, download the application and read the documentation on our GitHub! Leave a star if you enjoy us!
Thank you for your participation. Please leave a comment if you have any questions or suggestions on additional features!

A good candidate for worst website ever was Yvette's Bridal, a bridal shop in Florida. It's long gone but there is a copy here [1].

Modern browsers on modern computers probably won't succeed in capturing the full experience that was the site back in the day, because (1) the MIDI file that the site tries to play probably will just download instead of actually automatically play, and (2) if you play that file it will probably sound way better than it did back then due to way better MIDI instrument implementations.

"This other product that doesn't understand the appeal of Markdown and also thought this was a technical problem rather than a user barrier to entry problem made the same mistake" is not exactly a strong defense.

> Sanity. Sanity introduced to an ambiguous spec. It’s wonderful.

Users don't care how hard or easy something is to parse. You write a parser once; you write Markdown millions of times.

> Looks like it simply makes Markdown easier for both computers and humans! I love this and can’t believe I haven’t seen it before.

Unfortunately it does not. This is less readable and more annoying to write:

> - apple

> - orange

>

>djot:

>- Fruits

These are fundamentally different products. If you want something easy to parse and human readable, use YAML. If you want something easy to write, use Markdown.

Why did they not just engage in some sort of arbitrage situation? Seems easier.
Having worked with a lot of intelligent engineers (mostly EE) I would suggest that they are no more capable of making rational business decisions than anyone else.

The only thing I really took from the experience is to learn from other people’s mistakes because it hurts less than learning from your own.

My take home is that you should use a proper decision analysis framework for issues like this to test your own biases, reasonings and criteria. Sometimes your conclusion is not what you expected. Much pain saved.

> Why such variance in activation rates?

Yup.

If you invent an arbitrary metric and call it “activation rate” and then make a song and dance about how your arbitrary metric compares to the arbitrary metrics from some other company…

…well, you clearly wouldn’t be the only one doing it, but it’s also totally meaningless.

Internal metrics are good for presentations and for internal year-on-year comparisons.

Activation rate is a loaded term that means different things to different people, for the obviously stated reasons in the article.

Don’t use that term for your metrics; be precise and unambiguous.

(Imagine if you just invented some random crap related to your incoming/outgoing and called it “revenue”. Yeah.)
