> ”Liquefaction is the way. We already do it for natural gas (LNG), we just need to build similar infrastructure for LH2.”

It take a lot more energy to liquify hydrogen compared to natural gas. At least 10 kWh per kg. And storing/transporting it is expensive: you need to maintain cryogenic (-253 deg C) conditions.

Even the Space industry has given up on LH2 in favour of liquid CH4, partly due to all the costs and difficulties in handling it.
There was a recent story on a vertical strawberry farm in New Jersey: https://news.ycombinator.com/item?id=31454883. The quoted price (from the comments), is $20 for 8 strawberries. That's an order of magnitude higher than the strawberries at the supermarket. That does not bode well for the future of vertical farming, unless there's some miraculous breakthrough in cost effectiveness expected. As it stands right now you're better off buying conventional strawberries and spending the rest on carbon offsets.
I don’t have the same problem with long threat tweets, and in many cases prefer them over blogs as they’re forced to include only the most salient points.
This frustrates me. Right in this very thread are many accounts of people saying that doctors won’t listen to you and will do only the minimal amount of work possible to get you out of their office, and that you should do your own research. Then like 3 comments down are posts like yours, sarcastically putting down people sharing results of that same research.

So which one is it?

I don't quite agree. I mean, they provide useful service, and it costs money to run it. It's ok that they earn (even if it's actually making a profit, not just covering the costs).

That being said, 10 downloads/day feels a bit restrictive to me. I'd get if it was 100, or 50, heck, maybe even 20. I mean, I don't appreciate that it's not mirrorable in the first place, but maybe they cannot afford it, I don't know... But 10 feels less than somebody researching a new topic might need to access in a day, even if he won't read them all immediately.

…That being said as well, it has some really nice UI. I wish somebody did it for Libgen.
Wrong question to ask, PPFD's is the correct measure. It's not a direct energy comparison. Photosynthesis is a chemical reaction of Chlorophyll reacting to certain but not all light wavelength's (Red and Blue being the major ones) plus the distance from the light source. The amount of watts the the sun generates is NOT what grows plants. LED's can produce the same light wavelength's but much closer and with no obstructions. The question isn't about LED's power generation, it's how much power does it take for an LED to cover an area. Obviously a LED can't compare to pure Solar efficiency on a watt by watt basis but it doesn't need to.

It has a precise meaning. I've just told you what that meaning is. I'm an economist and I know the language of economics.

Regarding your other point, I'm not sure what you're trying to say. Are you saying that the dollar is not fiat money because it costs something to produce?

To be honest, I don't care. I have nothing else to add to this conversation, therefore I'm out.

In a world where corporations would rather literally kill their customers in order to generate gains for their shareholders, saying that regulations are put in place to "control" citizens, is the obvious naive take.

There are hundreds of examples of corporations choosing profit over humanity, famously recent ones are the opioid crisis and climate change. Let me know how you would fix these issues with just "education".
I have to wonder about the real-world applicability of any such simulation, under the assumption that the systems in question are chaotic, and so extremely sensitive to initial conditions.

Do we end up needing to simulate the whole world? Because, ultimately these systems are in fact one, and not separate at all.
I too first thought this had something to do with RED Engine 4 from CDPR.

Unfortunately CDPR's latest RED Engine 4 will not be released as open source in the forseeable future, it's basically dead and locked away, and will probably never see the light of day. Maybe it would be open sourced but in something like 20 years time.

click "Why Vite?". I think it has a pretty good explanation about what it is doing and the tools that are similar to it and the problem it is trying to solve.
> Yes but who is going to pay you the 2% for the remaining 9 months?!?!

Don't think of equalizing the terms by extending the BNPL. Think of equalizing the terms by shortening the CD.

> You’re incorporating a theoretical (and unrelated to 2% credit card rewards) interest rate into your calculations. I could easily say a CD yields 10% and this is a 50% APR then.

I'm not claiming that the ~8% interest rate is real. My calculations mean that if you can get that rate or better, then you should use 3-month BNPL, and if you can't, then you should use your credit card with 2% cash back instead.

> EDIT: Maybe to help you think about this: this is a purchase loan. It is not a cash loan. You got $1k worth of goods for $1k dollars. You can make arguments about opportunity costs, but that’s different than the traditional concept of APR.

I fail to see how that makes any difference.

> what’s the APR of cash purchases?

It's either the highest APR of any of your debt, if you have any, or the risk-free APR you could get from a savings account otherwise.

Slack is for synchronous shallow short form communication.

It is great for communicating around an event. Getting quick in-flow queries answered. Asking what people want to do for lunch.

It is not for substantial nuanced in depth communication. When used this way it quickly becomes a conveyor belt of distracting trash.

It is also not a knowledge repository or source of truth. Slack overflow is not a good practice.

Pro tip: have slack history clear after 60 days.

Better alternatives:
- Shared Google Doc with comments for analyzing an issue
- Meetings with a pre-read period and memo and clear purpose/outcome for the meeting
- Pair programming
- Live code review

TL;DR Dont use slack.
It's obviously not a real screenshot, since the codepoint overlay is a separate image.
Anytime you have distinct categories, remember that the model is an over-simplification.
But I’m telling you annualizing something like that is not convenience, it’s misleading.

Does every cash purchase also have an infinite APR? Because there I’m paying $200 for nothing. If that’s not logical then where does it start being logical?

The Revolution That Wasnt: GameStop, Reddit, and the Fleecing of Small Investors
I like that each tweet/paragraph can have its own commentary. Provided it isn’t anything political or bait-ey, the discussion following each tweet can be insightful, and are more contained and targeted than those usually found at the end of a blog post.

It’s important to remember that it’s just a different medium - you’ll find blogs, Reddit and Facebook posts, memes and infographics on this topic.
If you just take Western Main Stream Media, you just get the Western slant on things. And that is not necessarily truthful.

Learn to take news feeds from all over the world. Get a more balanced picture. You may be surprised that news from other countries that doesn't have a Western slant is likely to be just as accurate or even more accurate than Western News media.

The West is a mere one-eighth of the world. We in the West tend to forget that. China alone is half as big again as the entire combined West. As also is India.

The "Ukraine is beating Russia" and "Russia is running out of everything" rubbish that was all the go back in March, all of a sudden has to be walked back due to Russia's continuing gains. The 'other' news didn't bullshit back then and does not have 'egg on its face' now like Western News media does.

> They seem to have taken a good chunk of Ukraine just this past week

Only a minor one. Russians have taken some chunk in the East, they lost some other chunk on the South near Kherson, retreated from Snake Island in the black sea, unable to advance on the North around Kharkiv.

I don’t think these advancements is newsworthy, at least not for the global audience. In Donbass, Russian army advanced by ~20 miles in one isolated place, that’s over the whole June. Not insignificant, but not dramatic enough to generate many clicks on the google’s ads.

Hi, I was taking notes in Notability on a PDF of a manuscript I’m reviewing for a journal just before taking this break on Hacker News and finding this.

I have struggled to find one app to rule them all this regard.
While EU leaders are often given credit for EU actions, in reality the burden of the sanctions, as well as their implementation was decided by member states themselves. It s telling that EU did not have a plan (and still does not) for the ensuing inflation, and countries like spain had to act individually when it hit them first.

As for democracy in EU, i don't see it ever happening. In my mind the EU is a new kind of state (despite its horrible inefficiency), one that aims to work with process alone and not politics, and which can thus survive post-politics (in a way the US cannot). Given time, i would expect the commission and parliament to be replaced by AIs.
Yeah I remember starting a couple week streak in an app and then I had a long day with a work due to some issues and it reset my streak to 1 day since even though I did it before the end of my day it was technically the morning of the next day.

What rings true for me in this, is keeping your eye on what's most important to you, in my case, giving and receiving love, giving and receiving support and letting go of the outcome.
One of the benefits of dating a lot of people is you really do stop caring if the people like you or not, and let go of the outcome.

It would still use rebase in the background. If there's a conflict that happens when reapplying changes, then an error pops up, and the user can look into it and will start to understand the process. But in my experience of just doing quick patches on my private repos (where I do multiple small commits a day so patching an earlier commit is relatively common), a conflict rarely ever happens. I think I've run into it once in my many years of dev.

So for the majority of users, they wouldn't have to even know about rebase until they have quite a bit of experience with git (and programming in general). It's a better learning curve, especially considering Git is now being taught to beginner programmers.

A `git edit` command is not as powerful as `git rebase`, but this is just how UX works. You expose a smaller simpler set of features at the front, and then (if you aren't Apple) allow the users to do more advanced low-level operations if they need to.
Where I live, people already struggle with eliminating excess moisture from their basements. Putting growing plants there requires a significant upgrade to air ventilation and dehumidification, as it is the perfect breeding ground for mold.

As for LED grow lights, you typically use about 30-40 watts / square foot. That's a not insignificant added cost compared to growing above ground.

The added challenges to growing underground simply make it irrational.

Great job! I can see this being very useful, at the very least in the academia. For example, in meta-analytic reviews, you often go through hundreds of papers, identifying, highlighting and annotating the relevant hypothesis test details, among many irrelevant weeds. Tools that streamline this process are very handy, so that you can easily come back later and grok your past work. Pen and paper works for an individual, but can drown you in piles of binders, and is less easy to collaborate on/share.

Some quick, very minor UI comments: on a large screen, workspace switching could be available immediately through single-click icons instead of a dropdown menu. Similarly, minimizing open stickers could be done with a dedicated icon instead of through the “…” menu (right-click suggested in an example in the quick start guide didn’t work for me). Otherwise everything feels pretty intuitive.

One thing I’d want to learn from the introductory guides is if adding the metadata (comments, notes, highlights, etc.) changes the original PDF file (always, optionally, never?), so that for example you’d be able to send an annotated document right away, or need to keep backups of unmodified originals, etc. (I strongly assume the metadata is stored separately, as PDFs can be unwieldy to modify, but you never know.) In general, exporting/printing notes seems like a natural feature. I like that it’s easy to export clips.

As a casual right now, I don’t have any input regarding the possible business model, but will certainly be interested in where you go with it.

> Society has not agreed to this, which is why this is such a controversial issue.

I am sorry you have not realized that Trans people do not like being called by their old identity.

Would you like to argue why trans people like to be called by their old identity repeatedly?

I encourage you to ask trans people whether they would find it harassing if they are repeatedly called by their old identity.

I do not see how this can be contentious or controversial beyond people acting obtuse.

> Also, just doing something somebody doesn't like is not harassment.

Definition Cambridge dictionary tagged LAW for harassment:

> illegal behaviour towards a person that causes mental or emotional suffering, which includes repeated unwanted contacts without a reasonable purpose, insults, threats, touching, or offensive language

Was JBP speech illegal? We will only find out if Elliot sues and the appeals process has ended. It certainly meets other definitions from the same dictionary:

> behaviour that annoys or upsets someone

So, yes. Doing something someone doesn't like can literally be all it takes for it to be harassment.

> Should that count as harassment?

Yes, it might be harassment (in a legal sense).
If the behaviour upsets him yes it is in the normal sense. The behaviour is also toxic.

Twitter can (as it is currently private company) mostly decide it's own rules of moderation without input from society. It decided to give "race, ethnicity, national origin, caste, sexual orientation, gender, gender identity, religious affiliation, age, disability, or serious disease" special protection. Freedom from being called a bigot is not afforded, neither is political association protected (that would cover calling someone a bigot because he is a conservative). Twitter due to limited moderation resources has to restrict itself to moderating the important or often reported cases. In my experience toxic replies on Twitter are hidden under a spoiler in Twitter, below all other comments.

What can JBP do about it if it upsets him:
Statements of fact are usually excluded from laws on speech restrictions in the western world. He has any right to sue someone that this is harassment. He would just risk ending up with a situation where a court confirms that one might call him a bigot.
Heres a few naive options to get a ballpark idea:

A) fixed list of piece coordinates: 32 pieces × (3 bits for row + 3 bits for column + 1 bit for whether it's alive) = 224 bits

B) list of live pieces: (3 bit row + 3 bit column + 1 bit for color + 3 bits for which piece) × up to 32 pieces = up to 320 bits

C) 8x8 array of the board: 64 squares × (1 bit for color + 3 bits for which piece) = 256 bits

Then there's the gamestate that isn't directly visible on the board:

- whose turn it is: 1 bit.

- castling rights: A needs 2 bits. B and C can pack it in with the 3 bits for pieces. there's 6 pieces so there's room for two more, one of which is a rook that's eligible to castle with.

- en passant: A needs a flag for each pawn so 16 bits. B and C can also pack in with the other spare piece being a pawn that just advanced two spaces.

- promotion: B and C get it free. A needs another 3 bits per pawn to indicate if and what it's promoted to (so 48 bits max)

- 50 moves without capture/pawn move optional stalemate: 6 bit counter from 0 to 50.

- 75 moves without capture/pawn move forced stalemate: make that 7 bits

- repitition stalemates: don't see a way around needing to know the previous board states. you need a copy of everything except the 50 move counter for previous turns. you can prune states that are impossible to return to.

A: 301 + (294 × #repeatable_states) bits

B: 328 + (321 × #repeatable_states) bits

C: 264 + (257 × #repeatable_states) bits

I'm sure there's savings to be made further compressing any of these with variable length encodings though (see links in other replies). I especially like the idea of encoding information as illegal states.

edit: originally said 4 bits for row and column but it's 3.
Its source code is quite interesting. It's a medium-sized TypeScript project and it doesn't look like a C# or Java ripoff. Well done!

Software Mitigation of RISC-V Spectre Attacks
[PDF]: https://arxiv.org/pdf/2206.04507.pdf

"...In this paper we focus on the RISC-V cores where speculation is enabled and, as we show, where Spectre attacks are as effective as on x86. Even though RISC-V hardware mitigations were proposed in the past, they have not yet passed the prototype phase. Instead, we propose low-overhead software mitigations for Spectre-BTI, inspired from those used on the x86 architecture, and for Spectre-RSB, to our knowledge the first such mitigation to be proposed. We show that these mitigations work in practice and that they can be integrated in the LLVM toolchain.
