Efficiency as in energy/kg?

Tesla batteries: 207 watt-hours per kilogram (per google search)

Hydrogen: 120-142 MJ per kilogram (per google search)

Conversion from MJ to watt-hours: 277.778 watt-hours per MJ

120*277.778/207 ~ 161 more compact. Assuming energy conversion losses are equal.

Does anyone have any recommended references for books or websites that address strategy? So far I have studied Sun Tzu and Clausewitz. Any suggestions would be appreciated!
Somewhat similar project I've been working on: Live Coding in JavaScript and VR https://github.com/m-schuetz/Fenek

Video: https://www.youtube.com/watch?v=xhGNhKVAqW0

This allows you to modify the code of the VR render engine directly at runtime while you're in VR.
Incremental GC is very promising for games in favour of traditional stop-the-world GC. It's essentially time sliced GC that runs over multiple frames. Unity supports it and if you tweak if correctly for your needs the GC can run while the CPU is waiting for the GPU.
I would like to see a review of what it’s like to work on these environments. My sense is that the resolution and weight are real problems, but maybe that isn’t true anymore.

There is something appealing about being able to boot up a multi screen completely isolated environment for deep work.
> court has upheld an employer's right to IP that meets those three criteria (employee's own time, own equipment and unrelated to the employers business)

Yes. There are places where either by statute or by the employment contract, anything the employee creates belongs to the employer. The underlying concept is that the employer created an environment where the employee was able to learn and be inspired.

I know personally of a situation where a university exercised this right, although I don't know if they did it through statutes, common law, or an explicit agreement.
Why do they need to be industrial scale? Hydrogen electrolysis is fast, efficient, and can be done on any scale. Centralized production is likely never going to be as efficient as distributed production, simply because there are more losses in distribution than there are in electrolysis.

Thanks for this pg. Scheduled to have two new arrivals in about a months time. Positively shitting it as they are our first arrivals.

I don't think anything will prepare me for what lies ahead, feeling apprehensive, worried but looking forward to it none the less.

I've no idea how I'll manage time for our team in between diaper changes but I'm sure it'll all just work out for the best. Thinking positively.
That's just part of C and C++. When people do 'unity builds' to make larger compilation units the same rule applies. I think it is much more about avoiding the preprocessor as much as possible than some sort of fatal flaw with single header libraries. The advantages far outweigh the downsides since minimal dependencies means that you have real modularity. Pragmatically there is much more reuse with single header libraries like this. Search github for how many things depend on stb libraries and would not be possible without them or would end up with spidering dependencies and build systems.

Even windows.h redefines min and max - blaming single file libraries is ridiculous.

Using a single .c file that includes the file and defines the IMPL symbol would negate what you are saying anyway and in fact is a common way to use them.
Arvind Subramanian: It’s India’s Great Slowdown, Economy Seems Headed for ICU
> You could dump the core onto the seafloor and not really have to worry about anything except the fuel elements eventually corroding and polluting a small area.

Absolutely not. What you're saying is true for nuclear disposal- if you bury nuclear waste under the ocean floor there are no currents and no water table to disturb it, unlike on land where coolant water will rush towards drinking water, smoke does not diffuse evenly, and sediment does not naturally bury heavy isotopes.

It is absolutely not true for an accident. Radionuclides from Fukushima are measurable anywhere in the Pacific ocean. They're all over the planet. That's key though, because such even distribution means that even very dangerous isotopes are very quickly reduced to safe concentrations, or at least lower than background radiation.

On the other hand it is extremely difficult or impossible to save a priority environment if there is a real disaster. Convection will be driving far more radioactive material into the area than a land accident. You're not gonna ever have a meltdown (they already basically don't happen on land), but even a relatively small breach would have the potential to kill an entire area. Over most of the ocean that might be fine, but spawning areas or corals would be huge losses.
>This is a revolution for the whole world. Asia is 12 years ahead of the rest of the world. It is a time machine to the world,” he says. “The key point is not because they are better at tech. It’s because the demand for digital and mobile services is so much higher. They are leapfrogging generations of paying by plastic and cheque books to paying online through e-wallets.”

12 years ahead? Seems a patronizing number to put Asian fintech highlighted.

It’s not a switch, not in a meaningful way. It’s the time spent together that forms the bond. I don’t love my kid because I had sex to have him, I do because I taught him how to walks and speak, go to the toilet and play with marbles and had all kinds of fun in the process. I love him because every time I show him something new, or I let him have a spoon of my coffee (he loves it) there’s a wide smile appearing on his face followed by “I love you daddy”. Its the most validating, gratifying experience I had in my life, even if it’s a pain in the ass and I’d rather watch tv or tinker in the garage instead of sitting on the bleachers of this gym while he practices somersaults. If I adopted him it would be largely the same thing.
There is much confusion as there is both the Directive 2009/136/EC (aka EU Cookie Law) AND GDPR

EU mandated that all websites (residing in EU) to obtain informed consent before they can store or retrieve information on a visitor's computer or web-enabled device.

This is not limited to "cookies". The law doesn't even mention the word "cookie". It covers localStorage and any TBD technology in the future.

There are exceptions for "strictly necessary" like a store would not have to get consent to operate a shopping cart on the website as thats can be considered critical to the purchasing and checking out. However storing what you browsed for recommendation purposes is not, and therefore that would require consent.
If we ever get serious about climate change it will be illegal.

But it's going to be very hard because that means killing some profitable businesses, and right now profit is more important than the planet.
> Privacy purists seem to be surprised that website and app owners want/need analytics to meaningfully improve their app's usability.

Both "privacy purists" and many other people see this as expediency at best, and a lie at worst (i.e. once marketing gets wind of the tracking built for development purposes; see e.g. recent Gitlab fiasco).
In one discussion, I think with my own lawyer when reviewing a proposed employment contract, I was advised that it is best to be quite specific about what is covered with these IP clauses precisely because how enforceable they are can ultimately come down to the unpredictable opinion of a court where the people making the decision might not be technical experts.

It was a long time ago, so I may be slightly misremembering the exact details, but in a nutshell the example given was someone who did have to hand something over because a court decided that being a salaried programmer using a certain programming language at work meant something they programmed in that same language at home was related to their employment. The software itself was in a totally different field to what they did for work, so their assumption had been that it wouldn't be covered, but the court didn't see it that way. I'm in England and was talking to an English lawyer about English employment, so I assume that was also the location of the case mentioned, but I'm afraid I don't know anything more specific to provide a proper citation.

I was also warned that this is a bigger problem for employees of huge companies with many divisions, because in that case the employer could have interests in a wide variety of different fields that would be relevant for contractual purposes. Even though any given employee might have no knowledge that something they're doing out-of-hours could be affected, because it's nothing to do with what they do themselves and what happens in their own part of the business, it can still be relevant from the employer's point of view and so trigger the contractual transfer of IP rights.
Adding inches and raw centimetres is like adding apples and oranges, which they taught us not to do in grade school.

What you are thinking of is:

in1 = cm1.toInches();

If someone passes cm to a function that expects inches, much error and grief will result.
Google licenses from the same music publishers. They have to or they wouldn't be able to display the lyrics.

Just having a license doesn't necessarily give you the actual lyrics though. They still have to create or buy them from somebody.

In the past I think LyricFind said that when they licensed lyrics, some were provided by the publisher and it was the publisher that scraped them from Genius. I may be mis-remembering that, but there was something along those lines.

I think this is an issue of Genius alleging that LyricFind scraped their website with is a ToS violation.
Yeah I didn't have that instant flip. But after about 6-9 months, when they become increasingly interactive I started to enjoy it more. Before then it was more a sense of duty to help this tiny thing survive.

The decision to have kids is a lot like the decision to continue living. There is no logical basis for it. Or rather, any latticework of logic you erect to justify this choice is based on a foundation that has nothing to do with reason. It is an emotional and spiritual desire to live and love, and give more life and more love to the world.

That's why I when see people engage in complex rational calculations about the utility a child may or may not bring into their life, I feel like they are missing the point. Of course people ought to be thoughtful about the decision to have children. And there are very good reasons to abstain. But in a sense they are not grasping that having children is a profound act of hope.

I normally chalk these articles off as fluff/advertising. “How many of these companies really need a design system?” I think that question is still important; some companies prematurely optimize by spending too much time on this stuff rather than just building their product.

But this one I enjoyed going through. It was a good blend between visual presentation of the system, and commentary about the system.
Sorry, wouldn't work.

There are two separate offerings. AWS offers Aurora/Postgres which is a fork of Postgres with Amazon’s own code and there is regular RDS/Postgres which is basically managed Postgres.

> Storing H2 is really hard, I wouldn't bet on it.

That's not even the biggest issue for "the future": the "hydrogen economy" is based on cracking fossil fuels, producing CO2, so it's not exactly green.

Electrolysis is energy-intensive (50kWh/kg) and quite expensive, it's used for a small fraction of the production (2%) and mostly for uses which need very pure hydrogen (cracking fossil fuels yields pretty "dirty" hydrogen which is unsuitable for some applications).

I guess at capacity that would make it suitable as a sink to dump excess electricity from renewables in, but then you hit the storage issues you mentioned.
They’re coming. Mini announced all of their models would be electric in 3-5 years, I think. Most or all have some plan for BEVs in coming car generations.
My first 7 months with the newborn were exactly that: absolutely unproductive at work (got fired) and no time for anything of my own. And I was OK with it, because my only concern at the time was making sure the baby’s needs are met. After the initial 7 months passed, things went back to “old normal” - baby was much more stable and predictable, and I could get back to work.
If you need to build additional infrastructure why not use a technology that's used already.

The charging issue will be solved. There's lots of theoretical and lab proven work showing it can be done and will be achieved.
I experienced similar. My son is 16 months, and it's gotten way more fun.
Hydrogen Fuel Cells are electric.
Fantastic stuff, I might buy it
You are assuming that greater value generation is only a function of greater effort in the form of more hours. It is also a function of other things like higher talent, smarter decisions, and past investment in one’s skills.
> And this sounds definitely less efficient than using electricity directly.

Not necessarily. (1) There are losses transporting in storing electricity. If hydrogen was made on the spot, and if the losses storing and transporting hydrogen were smaller (unlikely), that would be a gain. (2) Hydrogen can be produced at solar peaks, when energy prices turn negative, and stored... huge (net) efficiency gain!
That doesn’t seem totally implausible to me, but even if it were, couldn’t they also just reuse the motor (etc) in a new housing?
AIVD ( Dutch Secret Service) Christmas puzzle 2019: statements and answer form
Hydrogen definitely is the future, it just may not be the future for cars. Much more likely to be used for transportation modes that have long running and consistent speeds. Long distance trucks, cargo ships, planes, etc..

The problem with cars is that they're so intermittently used and the loads are so variable. The only fuel cells that are really up to that task in particular are PEM fuel cells, which are expensive and inefficient compared to solid oxide and alkaline cells. Solid oxide cells might have a chance if used in a more plugin-hybrid form, where the fuel cell is used as a range extender.
So even if it’s obvious that there is no unique ID in there, you still need to show the notice?

We really need to lobby for a smarter law.
This is very true because yes, kids can be a lot of fun. They can also be exhausting, frustrating, terrifying, and just plain boring at times. That too is ok. It's kinda how it's supposed to be.

I suspect one of the reason Paul Graham views them the way he does is because he has approached them with a genuine sense of curiosity. If you're trying to mould them too much (a mistake I'm sad to say I've made too much) then things are going to be rough for both of you. But if you explore the world with them, placing boundaries only where true danger lies, then things can become really intellectually and emotionally interesting.

Also, you know what? Take some time for yourself periodically to recharge! You know what else? Let and encourage your spouse do the same! Also? Take some time together without the kids from time to time. Your kids might complain at the moment but you'll all be better for it in the end.
I refer you to his later point: "On the other hand, what kind of wimpy ambition do you have if it won't survive having kids? Do you have so little to spare?"

I'd argue that your ambition simply shifts upon having kids. If you channel that ambition into being a better parent everyone benefits.

And from an "accomplishment" perspective, I'd ask which of a would-be parent's projects are so world-changing that they'll be alive or still affecting things 70 years from now? If you're Elon Musk maybe you can make that argument, but for most people their kids will have more overall influence then their work ever will. So if you want to make an impact over the long term and aren't just satisfying an obsessive workaholic itch, kids can be a great way to do that.

>it's still possible to _objectively_ say that many people vote for ideological or sentimental reasons that appeal to them (which is part of democracy!) with - or without - having done (for example) a spreadsheet comparisons of how each candidate's manifesto politics would affect their cost of living, quality of living, economic expectations, and so on.

I disagree. I'd wager most voters do perform such an analysis, albeit in their heads.

People generally vote for Republicans because they want lower taxes. People generally vote for Democrats because they want better-funded government services. Most voting is really that simple -- people want their lives to cost less, and they vote for the party they think is more likely to deliver that. The ideological trappings are largely post-hoc justifications for why this self-interest is virtuous.

“ when our first child was born. It was like someone flipped a switch. I suddenly felt protective not just toward our child, but toward all children”

I appreciate that they included real examples of conversations they captured in the article, as disturbing as that may be.

A lot of the conversation around sexual predation, especially around child porn, is problematic from a democracy point of view: You get authorities asking for more power (usually, more draconian surveillance laws), without showing evidence of what it is that they are supposedly fighting -- and of course, nobody wants to ask too strongly for such evidence being shown, lest they be accused of being a potential predator as well. But we can't just give authorities more power just based on their say-so. Hence, my appreciation for the choice to release some of that material in the article. I'm against more draconian laws, but I do think people should be able to make up their own minds, and the discussions we have about those issues should be more open.
Given you want discount internal site traffic from being unique, you could add a query param to URLs as the user navigates.
Agreed. I think one way of looking at it is that building factories does not scale in the same way as building plants. You can build a plant that produces 1GW base and it can start generating when you turn it on. An equivalent factory making 250MWp of solar PV cells will take 20 years of production to build up to an equivalent installed base (when it can start producing cells to replace retired 20 year-old cells.)

If you try to scale up factories for faster growth you will have to start shutting them down when you hit an oversupply after 5-10 years and then where will your replacement cells come from?
>When someone can think up an argument to convince a Harry Potter fan that they should really judge Bach's music as more beautiful, pleasing, of higher artistic value etc. than Harry Potter, then I'm curious.

Such matters are not decided by arguments, the same way flat earth society members are not won by arguments (they heard them all anyway).

It's up to each person to make the effort to grow their understanding, which requires study and self-development.

>I think there's a reason why even die-hard Adorno "fans" have given up trying to argue why jazz music is so bad.

Yes, because mediocre commercial art prevailed in the end, and the kind of cultural development of bourgeois society declined.

Ironically for a good while jazz took a different route from the earlier kind of jazz Adorno criticised, much closer to those ideals of art. So it's more like Jazz post-50s went closer to Adorno than the other way around...

It doesn’t make you a better parent. But you shouldn’t feel guilty about your experience just because someone you respect wrote about their experience and it doesn’t mesh with yours.

You’ll make the hard decisions to do what is best for your kid but it isn’t always roses or easy as Paul makes it sound. I’m lucky if I have 3-4 experiences a week where I’m 100% in the moment and enjoying it. That is spending between 3-6 hours a day with my kids during the week.
The interesting thing here is that if you take a long-term holistic view, there is actually more productivity (literally an extra lifetime), more time for ideas, and more ambitions being added to the world. You can choose to instill your values in your children and watch them bring ideas you might've had into a world you will never enter.
