I don't think this generalizes. If you're a larger, more established company, sure, but most startups and small businesses can't afford to spend significant engineering time not building features that customers pay for. For those companies, there is a ton of value to hiring someone experienced who is at least somewhat familiar with your stack.
So you're saying that the threshold to getting into a fairly exclusive club (getting VC funded) is to get into an even more exclusive club (getting into YC).

I find it comical that the VC community thinks it is diverisifying its entrepreneurship base by backing the same network of people that moved from San Francisco to Austin or New York.

The truth of the matter is that capital might indeed be abundant, but it is going into much the same places it always has. The concentration of wealth and opportunity continues unabated.

I challenge VCs with all this extra money sloshing around to rethink the path to sustainable entrepreneurship. If this was the late 1800s, the money would all be flowing into steel mills in Pittsburgh and the emerging oil barons and tycoons in those cities that are very much ignored today.

Power satellites are interesting. But here's the thing:

For most aircraft (except some gliders), covering them fully with solar panels is not even close to the power they need in cruise, correct?

So a power satellite would have to generate _at least_ the same W/m2 as the sun (around 1.4kw/m2( just to break even with a solar panel, but most likely much, much more, by orders of magnitude.

For a 747, I've seen figures from 90 MW to almost 200MW. If the receivers were at the wings only, that would be almost 6MW per square meter if you take the lower figure.

For a target as small as a plane, this would look like an energy weapon from science fiction.

Even something like this would not cut it:

https://en.wikipedia.org/wiki/MIRACL

For general aircraft the numbers look better. Then again, they are much smaller.

I can't wait for power satellites to be deployed, but they will mostly be servicing ground stations.
Essentially, but it doesn't limit itself to the "working class". For example one of the problems of today's Italy is the north/south split in productivity (the "true value of labor"), but no accompanying split in minimum wage. The effect is very large (youth) unemployment in the south of the country.
Take the perspective of your average Chinese household. You have a century and a half of absolutely horrific events one after the other. The nation itself is parceled, invaded, and humiliated in various ways. Then after generations of poverty and misery the living standards don't just rise, but skyrocket upwards to the point where someone born after 1980 lives in a different world. Today, there are multiple opportunities to have a better life even for people in the poorest regions, where there previously was nothing. It is quite literally the single largest increase in living standards in history. If a person from that Chinese household told you that China is deeply flawed and doesn't always do the right thing, but that there are ideals worth spreading, what would you say to them?

Why is authoritarianism the defining trait of that civ, but somehow the centuries of Western colonization and subjugation aren't a defining trait of Western values? If the majority of the activity, funding and development of a military is to intervene in order to maintain economic and geopolitical interests, isn't that a better way to define it than vague abstract values like a soldier's code or "becoming conduct"? Does it matter that soldiers have a nice story to tell themselves when the end aggregate result of their participation is much grittier?

More broadly, aren't positive values the result of economic and political strength? Living standards are dropping and inequality is rising in the US, and the result was a semi-authoritarian and largely unqualified cabinet. So are Western values actually part of the Western character or a consequence of successful empire building and good economic conditions?
I'll read his article

> and 2m shares are given (technically, sold, but for some nominal sum like $25k) to you as the sponsor.

yeah I hate the ambiguity here and the article, are they given or do they have to purchase?

yes I understand the price discovery of the floating shares being used to value created shares for future dilution. thanks for clarifying, I thought it was in the acquired company.

are the sponsors able to sell some into market liquidity before the acquisition occurs? because the SPAC treasury would still have the paid in capital and could give all the money back if they fail, while speculators in the secondary market are just buying at a discount or premium but providing additional liquidity. I'm mainly curious what the market tolerates and what is standard in these offerings, its obvious to me that you can make any arrangement.
Holy crap I just figured the timeline there. 1989 he gets his first IBM compatible PC.

Within the small pond of PC shareware games, every single one of those was a hit. They had some of the best 2D art and music available in PC games at the time and were solidly fun. Some of them are a bit stiff by modern standards, but they were excellent for their day.

The fact that lots of people want to comment their package.json file and can’t easily due to Crockford’s decision does not mean that Crockford’s argument is nonsense. Crockford’s argument is not that there shouldn’t be comments in JSON because no one would want to use them. And again, I would also like to have comments in JSON.

Thanks, this is good stuff! Just to clarify one thing:

> You're comparing figures on generation to storage. Yes, a big nuclear plant that generates 2.5 GW of electricity often costs $15 billion … buying 2 gigawatt hours grants you the ability to store enough energy to output 2 GW for a duration of 1 hour

I'm clear on the distinction between power and storage capacity; that's why I said, "Li-ion was about US$111/kWh which is probably around US$300/kW on th[sic] current grid, depending on how many hours a day you need battery" and linked to my note from 02019 about precisely how the price of batteries interacts with the price of energy, depending on how many charge/discharge cycles you get per day and how long they are.

The thing I probably should have been more explicit about is that, on the current storage grid, batteries are needed about 2–3 hours a day; US$111/kWh times two or three hours gives "around US$300/kW": to bridge those 2–3 hours of shortfall, you need 2–3 kWh/kW of batteries. That's what makes Li-ion batteries profitable to install today.

It is of course true that as the amount of solar energy in the grid increases, this duration also increases, especially if demand response doesn't materialize as we might hope. Figures from the CAISO report I linked elsethread http://www.caiso.com/Documents/Final-Root-Cause-Analysis-Mid... show that California's solar generation in the summer is roughly 12 hours a day and fairly constant during about 10 of those hours, ending just after peak demand, and that peak demand is about twice "valley demand". On the fateful day, the demand ramped down from about 45000 MW to about 25000 MW nearly linearly over the other 12 hours, so if you wanted to feed the entire California demand from expanded solar generation, you'd need to store up 420 gigawatt hours (1.5 PJ). You'd need 12 kWh of batteries per (average) kilowatt, which would bring the price of storage to above US$13000 per kW at the battery prices I found two years ago, which is slightly higher than the price of thermal power generation. Hopefully those battery prices will go lower and/or people will shift to using more power when the sun is up, for example because it's free, but those prices are already low enough to invest the first US$50 billion into ramping up battery production and new extraction technologies.

Your point about service life is well taken, but I think you probably would benefit from doing real NPV calculations, with discount rates. I'll make an effort tomorrow if I have time.
Too expensive. Good quality Dashcam will run you a north of $300.
What's the end goal? To remove the need for naval ships to carry a supply of freshwater? They still have to have enormous supply chain and logistics figured out to keep fuel, ammo, food, medicine, people, etc. at the front lines and out at sea. I'd bet, if anything, the navy would be way more interested in figuring out how to run their ships off of saltwater instead of their people.
No, he means if something bad happens to Bitcoin, there are thousands of other cryptocurrencies for users to migrate to.

However since most cryptocurrency prices are denominated in bitcoin, a crash in bitcoin historically meant a crash in all of the rest.
> If what you want to say is that you think the government is run by a shadowy cabal of elites whose main purpose is to impoverish the common man, then just say that.

I’m not sure why I would need to go that far afield when I can just deal with the actual words spoken by actual economists where they literally say this with slighty obscurant language. This isn’t a “shadowy cabal,” its mainstream media and economics here.

If the actual intent of economic policy is so threatening to your worldview that you need to poison the well by invoking shadowy conspiracies, perhaps you should re-evaluate your own perspective on the issue.

> I'm just going to call you a conspiracy theorist because it's probably not worth arguing with you, and "the amount of energy needed to refute bullshit is an order of magnitude larger than to produce it."

Yeah it would probably require an infinite amount of energy to refute my assertions, since they are actually true. And I think we are beyond considering the existence of the central bank to be a “conspiracy theory”, it’s kind of established.
How are folks from India able to get vaccine here? Is there someone selling it to the highest bidder?
I'm not sure about "messing up the program state". Do you mean the memory error like segfault, or the `finally` block? My answer would depend on the answer:

Memory error: Instead of the register states for setjmp, call/cc and so on give you a well-behaved function of the continuation. I will spare what the continuation is but basically it's possible to convert any code into a code with the explicit continuation available as a function at any time (Continuation-Passing Style). So unlike setjmp/longjmp you can be sure that everything will be a normal function call in the end. (The actual implementation can of course vary.)

`finally` block: You are kinda right. They are used to implement things like more readable control structures like exceptions and cumbersome to use directly. There are things like `dynamic-wind` in the Scheme world, but it's true that if you weren't aware you can easily screw up. My point stands though, what you need is a non-local jump and not the exception proper. It just happens that the most widespread non-local jump construct is an exception.
Drag required to make lift is only a subset of total drag.

A car for example doesn’t need to produce lift, but it still displaces air which causes drag. The same is true of an aircrafts fuselage, which is generally not used to generate lift but still increases total drag. https://en.wikipedia.org/wiki/Parasitic_drag

Also, an aircraft is generally designed so that at cruse speed and altitude the wing incidence angle provides appropriate lift. https://en.wikipedia.org/wiki/Angle_of_incidence_(aerodynami.... Which means at optimal curse distance the cabin would almost perfectly level independent of optimal cruse speed or altitude.
> Now the SPAC is just a box containing $80m dollars (well, actually, significantly less than $80m due to all the bank fees, but let's pretend).

why would it be significantly less? the SPACs have underwriters and all the crap that normal IPOs have, unburdening the target company from doing this stuff?

I was somewhat imagining that the SPACs themselves have a very streamlined listing process and there is enough interest in the shares to not need an underwriter.

A SPAC could surely do a direct listing...

> The lockdowns we had in Melbourne to keep covid down were utterly harrowing and I think a lot of us are still processing that experience. We gave up some freedoms temporarily to save lives. It was a temporary sacrifice of personal freedoms, because not making that sacrifice would have been worse. Letting covid out would have risked the lives of my parents, and I would have risked long covid - and who knows how many complications down the road. And it’s proof we as a nation can take collective action when we need to. I worry that the US might not have been able to do what we did to contain the virus, even if the fatality rate was 20x higher than it is. And that’s a tragedy from the country that invented the internet and landed people on the moon.

I definitely agree with all of this.

Yeah, sorry my fellow peers in America are being pricks, and are being so mean that they are not just inflicting pain—-but are retraumatizing Australians (usually strangers) on the internet.

In the US, sadly, if somebody dies of coronavirus, then they are really nothing more than a statistic. It is sad but true. A lot of this existed before big tech, but big tech brought it to a totally different level.

I agree that America probably would not come together in solidarity to stop a virus 20 times more fatal. I have been so worried about where America has been going for the past 6 years especially.

Even if we do somehow get our act together, we will need profound structural change. We will need to flood our politics with ambitious positive plans in general in the future to stop this kind of stuff.

Also, the first 5 years of life determines many outcomes in life. It can set up a child to have an authoritarian personality for life, for example. To stop this, our government needs to put extreme emphasis on young children’s development so this kind of stuff can never happen again. I mean like hardcore investments, projects, and human rights towards the best development of young children.

The depths of how far low it can go are profoundly deep.

Your observation is bang on. I have expressed and argued this point of view to our community as well. I'm not sure there is an easy answer. I advocate strongly for a system that rewards doing something well, as an expert, and not being asked to do more. I don't want to be asked to design Mars landers, gourmet food (well, that might be fun), flight control systems, car brakes, etc. I do want to have pride and recognition for my hard work.

I was recently having a conversation where I speculated that with how bad some programmers are at naming things, some code reviews might actually be easier if you ran them through a code obfuscator first, so you can focus on what the code does rather than being tricked into making invalid assumptions by misleading names.
I would definitely use this. Very interesting idea. It's like a 911 for development.

However I do worry that more complex problems cant be solved over a phone call. So it has to be a context less question that's simply over my head. But I have had many!

I think as much as Nintendo can recover off of that property they should. The Atari 2600 sold as much as it did not because it was the best tech, but because it made the market through advertising. If you have supply, and you make the demand and/or there is demand, and you’re not concerned with staying on top, you can milk that cow.

FWIW, best climbing seasons I've ever had were:

- Once early in the season I tried letting a very fit fixie rider pace me up a canyon road until we literally couldn't pedal anymore due to leg muscle exhaustion. The fixie part is important because I had to stay in a much higher gear than I would have otherwise, and stand up and fight just to stay with him on the steep sections. We both collapsed and were near puking, and it took about ~15 mins of rest before we could ride down. Next day, before my legs had a chance to get sore, I did another regular climb. The rest of the season, I was unusually and noticeably faster than my friends. The workout where I pushed to exhaustion gave me a boost I didn't expect.

- Last couple of years I've worked up up to some longer rides, gone out for few super long rides on my own (50-100 miles). Having to work up the endurance to get through multiple big climbs in a ride, I've noticed, really helps me hold my own when I'm back riding shorter climbs with friends.

Generally just riding a lot will help too, technique comes with practice. Good luck!
Do not just track offset. If you have to deal with date/time locally, you must have the timezone. Treat this just like bytes/Unicode: accept local time on the edges of the app, convert immediately to UTC, store/use UTC internally, convert back to local on the edges at display time. Yes, it can get more complicated than this of doing calendar math, but I'm not aware of anything gained by just tracking offset.

>We don't say "perfection is impossible" when it comes to bridges collapsing.

Yes we do. People on the internet might not but look at the formal documentation that goes with any bridge plans. It will talk about factors of safety, various loads, environmental conditions and establish a set of constraints outside of which the bridge is not expected to perform as advertised.

>speed traders are dealing with million-dollar stakes and a single mistake can make the news

It's really easy to put HFT a pedestal when you can't inspect it up close but I assure you that for every Citadel and P72 there is half a dozen firms with sloppy software that goes absolutely crazy if non-ideal but foreseeable things happen. These people are making money hand over fist (kind of) by building to the minimum. There's one firm I want to name because of how much everything they have is held together with duct tape but they're nice guys so I won't.
The implication is that increasing prices might balance supply and demand better and/or increase profit for the manufacturer.
Not OP but... maybe in a situation where one would normally deploy spoilers?

Larger aircraft require a way to bleed off energy from landing (assuming additional drag from flaps won't be sufficient), depending on their approach. Smaller aircraft usually does not have speedbrakes and can make do with power changes and flaps.

Propellers are giant speedbrakes if not feathered. Maybe in a "speedbrake" situation they could be allowed to "windmill" and do some regen? Not sure how important this is as one would be normally landing very soon. Other situations that do not involve descent, just reduce power.
ok let me be more polite: source???

If you think your assertions are "actually true" then back them up.

edit: and let's be clear about who has poisoned the well here. You poisoned the well. You decided to go on HN and insinuate that governments are purposefully devaluing working class people's salaries to make their lives worse. An assertion that you provided with no evidence. And you expect that you can just post stuff like that without getting called out! Ridiculous.
The third great truth in this list is "an increase in the money supply leads to inflation, except when it doesn't" which is hard to argue with. Clearly a field where Nobel prizes should be awarded.

I can see why you want non-string scalar keys. In general, I do too. (I'm writing a data language that has them.)

However, I don't think it is useful to prod JSON (or a variant) to go in this direction.
You might (not) be surprised to hear this is a US centric practice. In Australia this behaviour would fall foul of consumer protection laws. Our Consumer protection act and government body has real teeth and these practices would fail the requirement not to engage is misleading and deceptive practices.

JSON doesn’t specify its numeric types: the mapping of a string of digits to concrete numeric types is implementation-defined: so, JSON doesn’t need specific syntax for BigInts or arbitrary-precision decimals.
