> While cabin air processing, one carbon dioxide removal bed is in the process of regeneration. Regeneration is accomplished using pressure/thermal swing methodology. First, the two-stage pump removes the free air from the adsorbent bed and returns it to the cabin, reducing oxygen ullage. Then Kapton heaters integrated within the adsorbent bed raise the zeolite temperature, and space vacuum creates a low, partial pressure driving the carbon dioxide gas overboard. Daylight and continuous day power cycle is overlapped with the operating cycle. In the daylight power cycle, the carbon dioxide adsorbent bed heaters are only allowed to be powered on during the day portion of the cycle

Converting CO2 into CO would be rather counterproductive (absent a reliable and efficient mechanism to remove CO), I suspect an efficient setup will involve "mechanical" filtration not chemical reactions.

> The biggest dairy companies in the world have the same combined greenhouse gas emissions as the UK, the sixth biggest economy in the world

The biggest dairy companies in the world presumably feed a lot of people. The UK is less than 1% of the world's population. Economy rank doesn't matter on its own. This is an obviously disingenuous comparison.

> More than 90% of the corporate dairy industries’ emissions are produced by the cows themselves, mostly in the form of methane.

So we're worried that too many cows are breathing?

> Research shows all plant-based milks, such as soya and oat, result in far fewer emissions than dairy milk.

And there it is. It's a hit piece.

Most dairy isn't consumed as milk. You can't make cheese or cream from a plant. Dairy is a big part of my diet, and I'm not replacing it with something that isn't even nutritionally equivalent.
I think you still need to improve and stop being annoyed by inefficiencies others have. You expect much from the people and this makes you unhappy.

I also though that spending time with people that do not bring direct value is not very efficient, but now I would say that best relationships are with people that are independent and do not want to get some value from you and are honest/happy where they are now.

Make a choice to be happy no matter if friends don't meet your expectations.

Credit to you for asking a very original question. I don't know anymore than I just read mind you but consider taking up a physical hobby of some sort. Preferably the kind that makes you feel like a little kid inside. Biking, rock climbing, martial arts etc (whatever it is for you). There is a thing we forget to do when we become successful, busy grown-ups and its called Play. And whatever you do, do not measure your time or progress in any way when you're playing.

For me at least, the impact of truly having a great time at something all by myself at least once a week makes me a far more intersting person. Also worthy of mention, going to parties is a total waste of time - and thats the point. Unstructured social time with a drink in the hand etc. Tell a few stories, have a few laughs and take a little play time.

This is the only reasonable solution for them though. If you don't close it like this, you could end up spawning a whole market, and you're no longer selling a product (maybe not the most "optimized" product, but which still satisfies all parties), instead you're competing against this market of your own creation.

"You don’t get coordinated responses like that without planning and practice."

I disagree. That's what makes this so much more difficult. If it required planning and practice, we could find the meeting place and itinerary and correct it.

This is much more subtle. This is the kind of thing you can get when you group like minded individuals together and give them power. Without directly orchestrating, they pick up cues and work together.

It's like when a company hires a new person and there's no rule explicitly saying they have to work overtime, but they see everyone else doing it and soon they are too.

Having used both MuseScore and Reaper in my workflow, I initially agree that scoring and DAWs are two different things, and that I could simply export MIDI files from the notation software then take let the DAW do the rest.

But I see the point of how good playback can affect the composition process, something notation software is not known for. Although I believe instrument quality should not be a cover up for bad compositions, there are undeniable instances where otherwise good compositions sound bland or uninspiring when played by the "lightweight" sounds bundled with notation software (as they are not DAWs). At times, after hearing it sound right within the DAW, with my favorite plugins and sound libraries, I am inspired to tweak the composition a bit, via the piano roll.

In such scenario, if playback could be improved, it would be nice if a DAW can be removed from the compose-listen-tweak loop. At the very least, have realistic instruments and realistic (humanized) playing, even before moving work into the DAW.

If there has been a rise in arson cases in my city that finally convinces me to get fire insurance, is that in bad faith? I have a reason to believe my house is now more at risk of burning down, so I'm buying insurance. It seems a much more realistic scenario than the one of having a arsonist slowly approaching a house (and even then, arsonist in general do not burn down most the buildings they approach throughout their lifetime, and even more so when you could individual approaches that result in arson).

What about someone who notices that they are getting older and are starting to develop aches and pains and decides to start buying health insurance that they had avoided when they were younger because they seemed to have been made out of rubber back then?
Interestingly, you should read up on Thomas Sowell's work and books. There are also plenty of videos on Youtube where you can get some distillation of his work.

Here are some of his "controversial" views:

1. Reduce the incentive to destroy the family unit by providing large benefits to single parents

2. School choice

For the first one, even the leftist economists don't dispute the distortions caused by these transfers. As for point 2, they'll always shriek about things even though it makes sense to tie the child to the money and not the money to the school. Parents will always suss out the better option and will send their child to a better school.
The microcontrollers in an ECU are built on far, far different processes to modern CPUs and GPUs. Microcontrollers are usually >90nm, and if designing for robustness probably a lot larger than that. These processes are optimised for many different things, but speed is usually lower on the list than cost, power consumption, and even lifetime (which the automotive industry are still extremely keen on). And given the strong (generally exponential) dependence such aging processes have on temperature, time spent in a low power mode while the engine isn't running as opposed to off is basically irrelevant as far as lifetime is concerned.

From the website because I was wondering if this was some ReactNative alternative or what they meant by native HTML elements:

> Native Elements (NE) is not a CSS framework, no bundlers required or tons of configurations to set. You can consider it as a customizable plug-n-play library for your site which helps you easily styling all the available HTML elements using CSS custom properties, classes, attributes, or whatever you want in less than 7 kB. You can also build your class-based CSS framework on top of it.

Seems interesting, but as a common web developer not uber ahead on next gen stuff they could really put more examples in the homepage outside of just a gif. My best guess is this allows you to create new HTML elements that have some default properties, which sounds nice enough. I heard the browser was coming out with this capability or related in the future, I always forget what they're calling it next but I'm still waiting on that, unless this builds on that?

As far as pure UX is concerned, Turbo Pascal and Turbo C++ are still a gold standard of text-mode IDE's.

Emacs has tried to add a bit of the same featureset lately, like it will show a primitive TUI menubar if you launch it from a terminal but it's quite half-baked; the look and feel is sub-standard, and mouse interaction (via gpm or xterm) doesn't actually work by default. (Of course I realize that capturing mouse events is not always desired but it should be reasonably easy to allow this, maybe even as a default.) And it still lacks other basic UX elements like floating windows for dialog boxes, or resizing/rearranging windows with the mouse.

FreePascal still ships a proper TUI IDE, and there's a FreeDOS text-mode IDE for C/C++ known as RHIDE.

Ask HN: Best Guitar Learning Resources
What would be your suggestions for the (should I say) "best" or more efficient way to learn how to play the guitar?

Yes, I know practice and perseverance will get me there, but what exactly is the right and most efficient way to build up on stuff to practice on?

Asking this on HN, and being a programmer myself, I would be more likely inclined to follow a strictly defined music theory rather than playing with ear, as I find "mathematical" notation easier to follow. Play by ear "might" come later when I get more experienced...? Not even sure if this last paragraph makes sense, I hope you get what I mean.
Microsoft Just Gave a Billion Users a Reason to Quit Windows 10
For quick sketches during sprint planning meetings or design sessions, I started using Witeboard.com a couple of years ago but have been experimenting with Excalidraw for the past two months.

TL;DR: I still tend to use Witeboard.com for quick sketches, but if I plan on doing something more complicated and not time-sensitive I use Excalidraw.

What I like about Witeboard.com:

- fast to load and easy to get started

- quick keys (t: typing, p: pencil)

- pencil modifier keys: hold down l to switch from free drawing to drawing a line, or r to draw a rectangle

Dislike about Witeboard.com:

- It's like MS Paint, once the pixels are drawn you can't move them around (despite being vectors (I assume, infinitely zoomable))

What I like about Excalidraw:

- Can move shapes around (fixes biggest gripe with Witeboard.com)

- Sloppiness levels: Artist is what I use and is PERFECT for my needs, but nice to have options for other users

- Also has quick keys (8: typing, 7: pencil)

- Exports editable drawing as a file, not saved in cloud. So you can just import that file again and not rely on saving the URL.

Dislike about Excalidraw:

- Preventing me from switching to it: once a tool (ie. pencil) is used for a stroke, it reverts back to mouse cursor (I'd rather have it stay as pencil and hit 1 for it to switch to a cursor)

- Majorly annoying: the open/save/color/stroke palette in top left is too similar to a square ratio, so it blocks a corner of the image

If those two dislikes were fixed, I'd likely switch to it fulltime. For both products, I'd easily pay a few bucks a month for them.

In theory it's possible to farm cows without using fossil fuel so yes, it could be carbon neutral (ignoring the fact that current production levels aren't sustainable).

This is what `npm audit` is for. It's not perfect obviously, but it should prevent the worst.

It's actually a brilliant move by Apple.

After the new machines are released, all Mac app store apps will just magically work because they were recompiled behind the scenes by Apple to run on ARM. Only independent releases (stuff not in the app store) will have to deal with the shit show, which will also push more developers to the Apple tax.

For regular Mac users (who are already using the app store for everything), there will be no difference, and nobody will care what's actually under the hood. All of their software will work just fine whether it's x64 or ARM. There's nothing to wait for because these ARM machines aren't going to be so much better that people delay their purchase. It would be like holding off on the 2.2L engine variant of a car because the new model with the 2.4L engine with 5% better acceleration is around the corner.

Of course the reality will be that some apps will break, but the majority will just work, and Apple will be working behind the scenes with the biggest fish to make sure their stuff transitions smoothly.

No, WebRTC is 1 to 1. Each connection is adapted independently. But, you can build services that have rooms with more participants, then it's up to you to shape the traffic as you want. If you use a central server (SFU), it can just send each peer the best they can receive, each independently from one another. It's a property of the service, not the technology.
