The more stages, the less favorable your ratio fuel+propellant / dry mass. When you add stages, you add engines, tanks, systems... that you then have to haul up to the next stage, making your lower stages heavier. Rocket equation again.

Sure it's possible that if you had super lightweight material for all the dry mass, 3 stages would make more sense.

You're right, there is a "real-world tradeoffs between efficiencies in the rocket equation and engineering parameters". This trade-off is unfavorable to SSTOs.
> Should we start rounding up Muslims too?

Some say yes, specifically some in the current administration... But ignoring my glib & pointless attack at a few powerful racists: this tangent of the tangent has very little to do with that the previous posters were saying.

The comparison would only be valid if rounding up the Muslim population has some effect on commercial interests specifically the giving commercial interests in the country doing the rounding up an advantage over those in the other country.

China made a big mistake in being too reliant on TSMC, etc. or maybe it did not have the capacity to go after too many targets. Or maybe it simply did not think it could be a problem.

They are quick to learn and adapt, though, not least when the Chinese state throws its whole weight behind something, so I'm thinking that after this initial shock, in a few years the result will be a decline of the relative importance of the Taiwanese semi industry because mainland China will have its own, with all the potential strategic consequences that this might mean.
> I really doubt that we will have a vaccine for the general population in 2-3mo.

Even so, the logistics I think will add another extra year (at least for the "Western" countries, which I'm pretty sure will forget about the "equality for all humans" mantra and will scramble to get first in line). For the roughly 3.4-5 billion people that we need to vaccinate in order to begin to get herd immunity I honestly think we're looking at a 3-5 year timeframe (at least).
Chip Fabs? Those are in Taiwan (until China started raiding them).
As others have said, there are other possibilities. Some good, some neutral, perhaps some bad (but in ways unrelated to how Facebook itself is considered bad).

A great many are there to build their skills and/or resumes, which is a lot more than just putting food on the table. There aren't many places where one can learn so much so quickly about certain technologies (like VR/AR) or how to run things at that kind of scale, and most of those (e.g. Google, Amazon) have their own ethical issues. Many other companies, including some HN darlings, were founded by ex-FB employees. Some of them are doing good things, for practically any definition of "good" you might apply.

Others are there because they believe in the good Facebook does as well as the bad. As you said, they're likely exposed to more information about what the company does, which means a lower percentage is of the "jealous columnist at NYT" variety. Facebook helps connect people and businesses in positive ways as well as negative. You might think the ratio is not high enough, but others can quite reasonably disagree and/or think it's worth their time to work on improving that ratio.

There are many other possible reasons as well. "Evil or trapped" is not a useful simplification.
Defund is not actually a bad idea. The police are tasked with handling the fallout of failing or non-existent social systems and have been scaled respectively - in fact police funding is growing every year, and not insubstantially.

If you work in tech you should know what happens if you transfer too many responsibilities to one bloated team.

These funds would be better invested in actual support systems. Homeless shelters. Drug rehabilitation. Fixing subpar education funding in poor school districts.
Not really, Trump wants to pull over 10.000 troops out of Germany because of an oil pipeline deal with Russia. The public opinion pretty much is that, while he's at it, he should also take his bombs with him. But the public opinion probably not is the best deal politically.

The plan is to relocate them to other bases in Europe (mainly Italy and Belgium) so in the big picture it really doesn't matter.
Still, we do it constantly: Any monitor/screen is just a "lightbulb", that we are staring into day to day.

I don't think it's a mistake. It's more that they don't have a choice. There are very few (maybe even only one?) foundries in the world with advanced processes. Building a foundry is not trivial. For how long has Intel stuck with 14nm now? The Dutch ASML lithography machine is one of the most advanced machines in the world, and it's pretty much the only one of its kind. China has been investing heavily in domestic foundries for years now, but it takes time.
True... though "588/user" is more digestable than "588/current user but likely accounting for future growth which is why there is a premium - though we can't be sure that userbase does continue to grow considering the cloud of uncertainty around this deal and that the user base is largely gen z/particularly young and it is not proven that they will be sticky"

They go on to acknowledge the growth profile and valuation multiples vs competitors based off projected profits ...which is probably the more useful way to look at it -

There have been reports of investors valuing TikTok around $50 billion in the takeover bid, this is approximately 50 times its projected revenue for 2020. Many publications have compared this to SnapChat’s market capitalization which sits around $33 billion at the moment (15 times its 2020 projected revenue). While Snapchat exists within the same social media ecosystem the comparison has to account for two factors.

1) TikTok vs Snapchat’s position in the growth cycle
2) TikTok vs Snapchat’s core proposition

After working on rust for almost 2 years, I finally reached a point where I can see (and wait for) a few improvements.

First is completing the `impl Trait` saga. I see a couple of areas where I'm obliged to box a trait to get the compiler to accept the code. Not the end of the world.

Second is allowing conversions of AsyncRead to Stream. currently you have to do a weird dance to get chunks of tokio::File as Stream of Bytes. I think something is missing. Something as straightforward should be easy even if it's not part of std.

Last, is adding support for Generators and their transformation into Stream. Then, getting a Stream of Val would be as simple as `yield val` in a function. I'm sure their current API on nightly will change before it's merged to stable rust, and I even hope they will get rid of the "return type" in gens (it complicates things a little bit).

After that last point, I can see Rust replacing python for most of the data prep work we have in data science/AI.
All people are vulnerable to misinformation campaigns, the problem is every one has lost interest in accurate information. The only solution people provide is that we need to get rid of the bad information instead of changing peoples motives.

Dictatorships can be elective, so raising elections is irrelevant,and they can result from a legal delegation of arbitrary authority to the dictator (both election and legal delegation were absolutely the case for the Roman office of Dictator, which “dictatorship” is a generalization from.) If the President rules arbitrarily without meaningful constraint, despite being elected and despite that arbitrary power being explictly delegated in law, it is a dictatorship.

It's not, though, because the President is neither delegated general arbitrary power in law not ruling with it despite the law. While constraints on executive authority in the law have significantly broken down and one might argue that it is on the road to dictatorship, arbitrary executive action despite the law still faces meaningful checks at least by the courts. There has been significant defiance of court orders without meaningful consequence (e.g., with regard to family separation policy) but the areas where that has occurred are still limited and noticeable, however deeply problematic, exceptions.
> “Seattle’s unprecedented decision to abandon and close off an entire city neighborhood, leaving it unchecked by the police, unserved by fire and emergency health services, and inaccessible to the public”

Is this what people advocating for abolish the police are advocating for? Removal of health services? Isn't it literally the opposite, to have more and more varied health (and social) services, that people are advocating for?

"Abolish the police" is a scale where there is an extreme end where they may call for completely removing police from across the USA. From what I've seen, that isn't what the majority who are calling for abolishment are aiming for. Maybe "abolish" was a poor choice of a word.

The more common level I've seen is advocating for replacing parts of policing for more appropriate systems and services.

I'd call this article a straw-man argument, but there are those on the extreme end of the scale, apparently.
You've skipped the most important part of the puzzle: Find something people want to pay you for and do that. Think of all the kinds of software and services that you can provide. Pick 3 that you know for a fact that people will pay for. Investigate those further and try to think of an MVP product or service you could offer and how much it would cost.

I also highly recommend YC's Startup School. It helped my startup enormously. And... watch every episode of Shark Tank; there are lots of free lessons from the sharks who've done this many times before.

xbox at first was so bad they buried it in another division that was very profitable. I remember reading it in their prospectus when I owned some of their stock at that time. xbox now is only 'good' because sony made the ps3 which was a cool box but expensive to buy, use and produce on.

MS has what I call the 6 versions rule. v1 do not get, v2 interesting toy, v3 hey kinda usable, v4 get this thing it is cool, v5 they manage to mess it up badly, v6 just kinda put that back but not quite. They then toggle between v5 and v6.

Oh, and we never killed mice - we "sacrificed" them (in the lab we said "sacked" for short).

Yeah, it never sat particularly well with me. We and other labs studied neurodegenerative diseases, so we studied a model form of those diseases by inducing it in rats. The Parkinson's lab adjacent to us gave their rats a drug that destroyed their dopaminergic neurons, we inhibited thiamine to cause severe memory impairment. Really horrible things, but I'm not sure that there's a good alternative if we want to study diseases so we can prevent or cure them in humans.
A reminder that police "do not owe a specific duty to provide police services to citizens based on the public duty doctrine."

> It's shocking to me how far ahead MacOS is in terms of keyboard shortcuts compared to all other operating systems.

I agree with your other points (including easier customizability), but have to completely disagree with this quoted sentence.

In my experience of using macOS/OS X/Mac OS X as well as Windows and Linux, macOS is one OS where a user cannot avoid using the mouse or trackpad!

On Windows (and mostly in Linux too), I can navigate the entire system, application menus and UI controls without touching the mouse or trackpad, relying only on the keyboard. The same on a Mac would be frustrating because keyboard navigation, especially for menus, is cumbersome. There are many Apple apps that cannot be completely controlled just using the keyboard either. There are many UI controls (including in dialogs) that just need a mouse or keyboard. When I find these instances, for me it's like death by a thousand paper cuts (note: I do have preferences set to navigate through all controls when hitting Tab).

If you disagree with my assessment, please try this using only the keyboard (no mouse or trackpad) and see how cumbersome it is (not to mention inconsistent in certain ways with the rest of the system too):

* Open System Preferences

* Open the Keyboard settings (just an example)

* Navigate from one tab to another within the settings

Of course, I'd like to know how something like this can be done faster using the keyboard.

Yes to your second sentence. I read kube-system's comment in good faith. It was providing community context.

I once got excited about what I thought was a cool idea (I can't remember what it was, but something along the lines of "black swan theory"). I didn't know how established it was, so I started inserting it in talks with the assumption people didn't already know about it. I belabored its definition and dwelled on it, when in fact people in academic communities had already discussed it in depth, and have moved on to other ideas. No one said anything, but no one engaged with me after my talks and I wondered why.

Looking back, I wished someone had nudged me and explained the context of that idea in those communities. I must have come across as a pseudointellectual (in that particular context). Feedback matters and is helpful when given kindly.

The first rule of money is, "Don't lose it".

As to what to do with it? If interested in shares, a rule that I like is to invest in companies that make products that you like. Also, hopefully, you can make some assessment about the management of the company. If they are bringing a new product to the market, can you use your expertise to evaluate that product?

Michael Burry argues that Index Funds distort the market. Think lemmings. Better to use one's own judgement.

More coal plants is incorrect and the shutdown of the nuclear power plants was planned anyway. Since the mid 1980s no less...

Basically most of the plants that were shut down simply didn't get their runtime extended again and would've been shut down in a few years anyway.

And the utility companies owning them get billions in compensation and don't have o pay for waste disposal of all the irradiated parts either...

Facts that nuclear proponents always conveniently ignore...

The business model wasn't selling the service, but as with many security personalities, buying attention. People in a fairly wide circle know who Troy Hunt is. He can probably get a good honorarium, flight and free dinner for speaking to the Kentucky Association of Banking Compliance Officers or whatever.

It's probably reaching a point where the return on announcing breaches is declining, and the potential value of selling data of questionable origin to a legit entity is very challenging. The dataset gets less valuable every day because anyone can start collecting breaches today, and the value of old breaches goes down -- who cares about an Adobe account leak from 2012?
I can understand the US decision of banning huawei reasoning for national security, but case against TikTok is not something I grasp understandable.
Even India(where I live) banned Tiktok. At first I believed,its just temporary and will be lifted in few days but it didn't.

These types of actions will not benefit anyone, just toss name of china with other country in above scenario. It will be something like,

- EU banning Tesla because of its USA origin

- US banning Reliance/Tata because of its Indian Origin

- Russia banning google/facebook to favor their local companies

- etc.

This is something that should never happen,but sadly it is.
What kind of "posts written for developers" are you referring to? Since the dawn of software, there's been disagreement been the sales and marketing people and the developers and support folks. Usually the issues are around salespeople incorrectly describing or over-selling the product, leaving devs and support people hold the bag after something less-than-desirable is delivered.

It's difficult for non-tech people to write highly technical information that is accurate. Programming documentation, especially, requires people who understand programming. Sadly, many of the best tech folks are not good communicators or marketers because their writing lacks impact and interest.

We'll always have some version of this disconnect.
