can someone explain to me why you would use RH over something like Fidelity who has 24/7/365 support and no commission trades? honestly the first thing i do when it comes to a service (especially financial) is see if they have a way in getting in touch with someone 24/7/365. i would rather pay to know i can call and talk to a human then save money. seems like these people lost dollars tripping over pennies. even if a trade cost $5 a trade, i would still pay it just to know i can reach someone.
It’s not worth optimizing for.

There's common interests between the nations and modern technologies have helped facilitate the exchange of both goods and ideas, but I doubt if we can call ourselves a "global civilization" just yet. That would mean some sort of world government, which we definitely don't have. And to me, that just means that the rules of the game haven't changed at all.
I used to do this for job postings in target companies and a few other purposes in heady era of 2008. One of the hassles is that some pages do not neatly contain their useful data in json, so the tiny deploy script becomes a little more complicated to support the various steps:

1. Collection: logins, curl

2. Pretty print: jq / tidy

3. Selectors: Beautiful Soup / jq

4. Annotation: svn / git commit

The Github Actions angle is new and welcome though.
Not at all. This is a place I post my honest thoughts on things regardless of the points. Sometimes I'm downvoted, even ridiculed(perhaps fairly), and I take zero offense to any of it. Similarly, I get no 'high' off something that scores upvotes. I think HN does a pretty good job of helping this by not showing everyone's score, not notifying you someone replied to your post, not having reactions, etc.

OK, I probably misremembered the different numbers from conversion, compression, transport, etc, but the overall figure was that generation to wheel efficiency was in the realm of 20%, while generation to wheel with batteries is more in the 85% efficiency range.

I was asking a simple question. There are people here who know economics better than I, so I wanted to know what would happen. People just assumed I don't want others to have a good life when that's so far from the truth.

Protest permits really defeat the point though.
I have this question on my mind and if someone could explain this sincerely I would be very grateful.

Time after time, YC startups seem to engage in practices which are unethical or dark or downright scammy. Be it Homejoy, uBiome, AirBnB (updating consent without asking). They seem to employ aggresive marketing tactics. They work under assumption that "law does not apply to us". Although this is true for ultra rich people, why regular seed funded do it? Is growth focus this much necessary to the to do outright fraud or in engage in shady tactics? They are willing to kill other people's business and livelihood for their growth. I would call this "preying tactics"

Paul is very successful person and I read about him a lot. Why companies going through YC do this? Or is this just Business-as-usual (BAU) in Americas? Kill or be killed?

Thanks for responding!

> [...] but they generally those aren't the top picks of pros (or hobbyists for that matter)

But that's exactly what I said: the complaint isn't that there is no software available. The complaint is that VERY specific software isn't available.

There's Gimp, Krita, and Darktable for image- and photo editing, but people still keep asking for Photoshop. More often than not the very same people, mind you, who also complain about Adobe's subscription model and pricing in general!

They don't want to be able to do the same work - they want to do the same work the exact same way using the exact same software. Same goes for video editing as well - there's kdenlive, OpenShot, DaVinci Resolve, Lightworks, and yes, even Blender can do it. But, nope. People want Premiere, Sony Vegas, and Final Cut - the rest doesn't even cross their mind.

That's the issue at hand - not lack of software. It's unwillingness to learn (pros don't count - they have different needs and concerns) and all to often just plain ignorance of alternatives.

The big ecosystem of smaller utilities is met by FOSS - here marketing and communication (as well as terrible naming in most cases) are the biggest factor.

Plugins and special drivers can be a problem, I fully agree with that. The question is however, whether this is relevant for hobbyists and people who just want to get started.

Seeing as special drivers are only required for special hardware (graphics cards and studio equipment comes to mind) and that plugins can easily exceed the cost of a small workstation, we're starting to leave hobbyist territory again.
I agree that for many people a slick video is enough. I personally devoted a significant chunk of my life to avoid that which simply isn’t tenable for most people. Still looking into the mechanics of say DNA deep doing to encounter chromatin means you can start to reason about what’s actually happening. Keep building a slightly more than superficial understanding of everything from Architecture to Quantum Mechanics and eventually you run out of major fields of study. It’s far from comprehensive and you really need to focus after that, but it’s something.

So sure, I don’t know the exact CGI line, but it’s something I know quite a lot about. Could a ‘deep fake’ style video effectively be good enough to be indistinguishable from someone actually talking? I suspect not yet, but I wouldn’t want to take the bet. But I know enough to realize the specifics around chaotic fluid simulation is a vastly higher hurdle due to the underlying computation involved.

Granted, drawing that line requires an understanding of what Military’s can pull off, which ultimately comes down to physics and economics. Now, I have actually done R&D for them so take of this what you will. It used to be military hardware had a huge leg up, but that’s far less the case today.

Getting to the point where you hear someone say “salt used to be worth as much as gold” and you think “that’s got to be BS” doesn’t take a deep understanding of history, just a supernatural understanding of a few related topics.

There's an other issue here: Evans bootstrapped herself by getting a (relevant) degree.

The spreadsheet story is nice, but even having these skills back in the 80's was way less common than today. The article should also have looked at how much tuition was relative to the cost of living/salary Evans was making, and if Ramos could afford it today.

Thats why they invented the joint stock company. Individuals invest their surplus wages in a joint venture in order to gain access to capital that costs too much for any one of them to afford.

They also capture these gains because the increased productivity of the company results in more products of greater value on the market. In short, they benefit as consumers.

This is exactly what I'd do as well. But let's think in a more broader terms. For example in my house we organize good by type. Fruits go in one place, meat in another, milk and milk products in third etc. But, isn't a context-oriented organization more reasonable? Food for breakfast goes in one place, food for dinner in another etc.?
Wouldn't that be relative, too? Eg if "total wage"'s point was to show lost benefits, the cost in the implied benefits would be relative to what those benefits relieve you from.

Which is to say, insurance these days might be worth vastly more than it was in 1968, since Healthcare costs have skyrocketed for the uninsured.
Of course context matters, but you're still conflating or redefining words here. Each of your examples is an example of implicit agreement, not explicit, because of the context provided. That's what context does ... it allows you to make an inference about how people are feeling or thinking about a certain topic when they don't explicitly say so. Your inference may be right, but it may also be wrong.

If in your parent comment you had accused Coinbase/Armstrong of implicitly supporting the status quo (as you define it) I would've said "yeah, sure, if I squint hard enough and wash it through the 'silence is violence' filters I can see how you'd think that".

Another troubling thing I want to point out here is your comment is part of an accelerating trend where people, particularly from but not limited to those on the left, consistently attribute maximum malice of intent to peoples' comments (said and unsaid) or their actions. That is, imo, one of the reasons these environments are so toxic, because people are immediately put on the defensive.

> It's a fundamentally selfish viewpoint that you instead of the site you're using should decide how you consume what the site offers, a point of view that would be considered patently outrageous in many other contexts.

I'd argue the opposite. It's fundamentally selfish for a site to assume that _it_ gets to decide, without my agreement or consent, how I must consume the content it has freely and unconditionally sent me. If a site wants to negotiate a fair payment in exchange for its content (whether that payment be currency or merely displaying ads on my screen) it is free to do so, but without a mutual agreement neither party is under any moral obligation to the other. I'm not obligated to view the site in any particular way, and they're not obligated to serve me the content.

While this article focuses on the Victorian era, another very recent and highly entertaining narrative is the podcast about the search for evidence for hallucinogen use in Ancient Greece, Ancient Egypt, Spain, and elsewhere, and the potential tie of usage to religious history. The prospect of hallucinogens driving central parts of ancient history is tantalizing, and the speculative conversation (it’s Joe Rogan after all) is a nice treat for commuting time.

Why call it "Biggest Y Combinator Failed Startups," and just randomly pick on some very small companies that weren't even contacted for their side of the story?

Like, what could anyone learn about from what you wrote about, for example, the vegan milk startup? You just picked on a random small company, and then said generic stuff about "economies of scale".

I love hearing about failures (and am happy to talk about my own!), but there's a difference between exploring what went wrong, and "punching down". Now when you Google their names, "Biggest Y Combinator Failed Startups" will be the result. Unfair.

> Without Apple, instead of creating an app you would have to create an app and the platform and distribution mechanism etc.

And? As Brent Simmons of NetNewsWire et al observed:

> We started selling over the web in the mid ’90s.

* https://www.forbes.com/sites/robpegoraro/2020/07/29/what-tim...

He says they'd give up 5% to a payment processor, not 30%. John Gruber:

> To omit the fact that there was — dating back to the mid-’90s, well over a decade before the iPhone App Store — a thriving market for software sold directly over a thing called “The Internet” is sophistry. Most Mac software is still sold and distributed this way today. If App Stores are so great why is most Mac software sold outside the Mac App Store?

* https://daringfireball.net/2020/07/parsing_cooks_opening_sta...

And you don't have to build it yourself, as there is now SaaS for all of this, and I'd hazard to guess that they'd be less that 30%. For example the Carbon Copy Cloner folks redirect to a third-party:

* https://bombich.com/store

And even if they took 30%, you'd still have the freedom to write apps the way you want and not be beholden to Apple's guidelines.
Your objection misses the mark.

There is no singular "energy storage problem". There are various energy storage problems. All hydrogen (or batteries, or other storage technologies) have to do to be viable is address one or more of them. No storage technology can solve all of then, and no single storage technology has to.

Hydrogen is best suited for long term and infrequently tapped energy storage. For that use case, it is vastly superior to batteries, even if its efficiency is much lower. And this use case has to be solved to get to a 100% renewable grid.

Even aside from that, realize that today 6% of all natural gas consumed in the world goes into making hydrogen, mostly for manufacture of ammonia. So this use ALONE -- which amounts to 700 cubic kilometers of H2 (at STP) per year -- is a vast market for renewable hydrogen production.

I have in the past been very critical of some web pages for poor readability. When I first read this page I didn't think it was that bad. I have seen web pages designed by professionals that are much worse: tiny fonts and really low contrast.

If you are using Firefox there is an extension named "Tranquility" that does a reasonably good job of correcting readability issues. I don't know if there's a similar extension for Chrome.
It isn't a problem in Julia editors.

You input characters using the same notation as latex (IE \mu or \hbar) and then tab autocomplete to unicode. Even jupyter notebooks support that convention. Most people in Julia's target audience know latex already and so there is zero learning curve.

It did hugely simplify my scientific code where I already had variable names like hnu, omega_squared, and k_prime_prime which become arduous when checking against long equations.

You are tricked by what you see. You assume the other person is a person that looks like you but is rotated towards you, while in reality the other person would need to be a mirrored version of you.
Your brain doesn't see that it's mirrored because you are used to see "yourself" this way.
Here is an even more interesting example which was wireless as well.

https://en.m.wikipedia.org/wiki/The_Thing_(listening_device)
There are a handful of examples on Wikipedia: https://en.wikipedia.org/wiki/QUEL_query_languages. One example:

retrieve (a=count(y.i by y.d where y.str = "ii*" or y.str = "foo"), b=max(count(y.i by y.d)))

Not a particularly clear 'jumps at you' obvious semantic:

* Are a and b aggregation functions or window functions? If aggregations, how do they compose if the 'by' scopes are different?

* What does max(count(... by ...)) mean? What is the aggregation (window?) scope of max?

* How would an outer where clause compose? What is the evaluation order?
I do plan to go back farther in time; I think it will also be interesting.

The claim about RCA seems unlikely. Radio Corporation of America stock grew very fast through the 1920s, peaking in September 1929 before the crash. However, even at the very end, it doesn't seem to even have been top 10 among industrials in the S&P index: http://piketty.pse.ens.fr/files/McGrattanPrescott2001.pdf#pa...

Instead, on that list we have companies like General Motors, General Electric, and Standard Oil of New Jersey that were still big in 1960 (and as mentioned above, some still so in the last decade).
They rate USA 75% for corruption, and the (ex) British colonies as 100% for corruption. What does that mean? Is literally every single transaction in those places corrupt? "Out of 4" seems like a very poor way of doing this kind or rating.
I didn't quote a 0.35% death rate. That represents a possible upper bound on IFR based on data so far. Even in a worst case scenario it is impossible for 100% of Americans to be infected. Your simplistic estimate is missing critical variables.

I never claimed that any number of deaths is "okay" so stop arguing in bad faith and putting words in my mouth. Panicking is irrational and never helpful. We need rational, science-based policies now more than ever.

Certainly we should save as many lives as possible, but we can't get tunnel vision and focus on COVID-19 to the exclusion of all else. The lockdowns also kill people. They die slowly from lack of medical care, depression, substance abuse, and suicide but in the end they're dead all the same. It's like trying to run a business by focusing entirely on revenue and ignoring costs.
> Now many stores have intelligent inventory tracking that requires little to no work from employees.
> Why isn't the benefit of that efficiency passed on to those employees who are now more efficient?

It is, though, right?
It is passed on to the employees who were responsible for the efficiency gains. Those employees who built those innovations — could be employees of retailer, or employees of the companies, say tech companies, for whom the retailer is a customer.

I think the parent commenter’s point is still valid that:

>>Someone stocking shelves in 2020 is about productive as someone stocking shelves in 1968.

I would phrase it slightly differently: “the skill of stocking shelves in 2020 has been as efficient as it has been in 1968”. It’s the skill of creating innovations in inventory tracking , better statistical modeling and predictions/estimates, and probably the advent of tracking all this in digital systems that has multiplied the efficiency at the macro level.

Employees who are stocking shelves have not been able to participate in those contributions.
Also, the energy of compression can be substantially recovered when the hydrogen is used.
Median (average) measures are the refuge of the scoundrel.

Refuting the (willful) abuse of statistics is like trying to refute numerology with reason.
Apple has 100% market share of iOS application distribution and therefore has a monopoly on this market. In this position they can freely and arbitrarily govern what is and is not acceptable iOS software as well as how much it costs to produce and distribute iOS software with absolutely no competition that could benefit participants in this market. Allowing Apple to continue exercising absolute power over iOS software distribution does nothing but bolster Apple's revenue and hurt iOS software consumers and producers by limiting options and driving up costs.
Does YC invest in startups that have Iranian citizens as co-founders? Are there any limitations in accepting those applicants?
Looks nice, but as you say that just searches the current page. Here's how I search my entire site with slightly fewer lines of JavaScript:

// Construct the API query
const apiEndpoint = 'https://searchmysite.net/api/v1/search/michael-lewis.com';
let urlParams = new URLSearchParams(window.location.search);
let queryParam = urlParams.get('q');
if (queryParam == null || queryParam == '') { queryParam = '*' }
let apiQuery = apiEndpoint.concat('?q=', queryParam);

// Build the results (using fetch rather than XMLHttpRequest)
fetch(apiQuery)
.then((resp) => resp.json())
.then(function(data) {
let searchResults = data.results;
document.getElementById('query').value = queryParam; // Set the value of the search box to the query
if (searchResults && searchResults.length > 0) {
return searchResults.map(function(result) {
// Each result is going to be displayed as <li><a href="${result.url}" class="title">${result.title}</a></li>
let li = document.createElement('li'), a = document.createElement('a');
a.appendChild(document.createTextNode(`${result.title}`));
a.href = `${result.url}`;
a.classList.add('title');
li.appendChild(a);
// Each result is added to the <ul id="results"></ul>
document.getElementById('results').appendChild(li);
})
}
else {
// If there are no results update the <h1 class="title" id="results-title">Results</h1>
document.getElementById('results-title').innerText = 'No results';
}
})
.catch(function(error) {
console.log(error);
});
The market for Levine is certainly there. He could easily clear 7 figures on Substack.
In the 70s engineers in CEA in France modified some cars on the campus to run on liquid hydrogen. Apparently burning hydrogen in a combustion engine is pretty straightforward. I think that's the plan about future H2 planes, make them use turbofans slightly modify to burn H2 instead of kerosen.

However the big problem is storing H2 onboard. Most of the fuel is in the wings, and very cold liquid hydrogen (icing) as well as very heavy high-pressure tanks won't fit there. That's why I mentioned that an entirely new concept may be necessary to make room for the fuel tanks inside the fuselage.
