I do agree that it may foster politeness, but there are other undesirable effects of this cooling, such as political suppression. Sure, in a democracy like America, we love to tell everyone what we believe, and often it isn't polite, but in a place like China, it's beyond impolite to speak ill of the government, even when the criticism is just. I hate to invoke a slippery slope argument, but if we become timid around the subject of expressing our opinions, we may be easier to suppress. I would also like to add that there is an inherent value to speech. For example, a person who reveals government biases through photo or video is more valuable than a person who posts baseless conspiracies, hopefully we can have a proper value system socially enforced, rather than just have it all pushed down together
It's worth pointing out that this holds true for the inverse scenario: dark pools (trading between large firms off-exchange) are legal. The metaphor would be an artist selling only to his friends, and not putting every piece for sale for everyone.

> It feels like good marketing is finding that would be of value to me and to get it in front of me in a way that is unobtrusive

Bingo. I believe at the heart of this matter is a top down vs top up perspective.

Some people see the world as 'powerful people manipulating the masses using their Machiavellian techniques'. IMO these are the people who hate marketing the most, it's built into how they see the world.

Some people see the world as 'the masses control the world through their choices and the leaders ride the waves of popular sentiment'. These people see marketing as mostly benign.

I tend to see it a bit as both, with some feedback loop between them, but primarily the latter.
I have spent probably thousands of hours writing random responses helping people on forums, just because its the thing that I do to procrastinate. For example, this year I wrote more than 4000 posts on https://users.rust-lang.org/ and 19000 messages on the help channels in a few Discord servers. I'm probably the world expert at spotting the mistake in small snippets of Rust code at this point.

I honestly wish I was able to channel this incredible amount of writing into blog posts or a book, but I don't know how. My blog has had one post in the last three years. Writing a blog post just takes energy in a way that writing on forums simply does not.

It's always been this way too. For example, in high school, I spent the time on https://math.stackexchange.com/.
Especially since Citizens United gave your employer outsized power to change the government.
Perhaps people censoring themselves is the reason you see crazy things, insults, conspiracy theories, hate, etc. The rational and well-mannered people aren't taking the risk so all you hear is those who will take the risk.

It's why politics is full of goons. Who in their right mind would go into that arena, to do good, when the risks are so high, the exposure so great, the hatred so guaranteed? Just the wrong people willing to take the risk.
I think in the context of India it is unfair to call 10% population as Minority. 10% of Indian population is ~135 Million, that is more than the population of several countries.

i'm not sure why you're getting downvoted because this is, as far as i can tell, the central point of the whole piece: the most important thing you can do for making a properly immersive, high-quality video call is to isolate yourself away from background noise. once you've done that, then go ahead start geeking out over the quality of your mic, your camera quality, your backlighting, and all the other details.

but if you can't isolate yourself from background noise, then there's no point in getting fancy equipment for the rest of the stuff. just put yourself on mute and use your laptop's built in mic and webcam, because nothing you try will fix the background noise.
Oh, thanks for the correction. It seems I forgot that type existed or just never knew. Now I'm curious about the relative merits. I'd guess the transition is not as smooth and presents some kind of a risk that's unacceptable for critical infra.

This is also a reason why it might make sense to hold off unless you have some kind of time-sensitive project.

Nvidia came to dominate the market at a time when AMD wasn't making particularly competitive GPUs, but that isn't really the case anymore. For anything not so expensive that nobody is really going to buy it anyway, the current and expected (in less than a month) AMD GPUs are competitive on performance.

The result is that a lot of large customers, who see value in not being locked into a single supplier, are going to be pushing for frameworks that work across multiple vendors. And then you could plausibly be wasting your time learning Nvidia-specific technology which is about to become disfavored. So you might want to wait and see.

The density is actually lower than the sun in magnetic confinement fusion (MCF) devices because we can’t squeeze plasma together as hard as the sun’s mass can. Inertial confinement fusion (ICF) can squeeze harder than MCF devices, but has serious unaddressed engineering issues.

The trick is in higher temperature plasma. The sun fuses protium (lone protons). We don’t have the confinement necessary on Earth to do this, so we fuse deuterium (1p+1n) and tritium (1p+2n). This reaction is more energetically favorable and is achievable on Earth. Coupled with giant microwave ovens and clever geometry and electromagnetic tricks, we can make plasmas much hotter (faster moving particles) than the sun can.

Once a plasma is fusing, it emits a lot of heat (alpha heating and fast neutrons). A plasma that requires no external heating (no microwave ovens) is said to be “ignited”. We don’t necessarily need or want ignition to have a successful reactor, but it’s a cool thought.

The major trouble with fusion reactors is keeping particles in the bottle long enough to fuse. Since they’re leaving anyway they have to go somewhere. You can tune vessel geometry and magnetic fields to have designated strike points where most of the plasma will exit confinement. These are called divertors. Run some coolant through your divertors and you have a heat source that can boil water and spin a turbine.

Here my knowledge gets shaky because I know that the fastest particles coming out of a D+T reaction are neutrons (they weigh much less than an alpha particle). Since neutrons are electrically neutral I think they are much less likely to become thermalized (they are not likely to bump into another particle on their way out). I’m not sure how neutron thermalization happens in reactor simulations, but I’m under the impression that it does.

I caught that, but I still appreciate your taking the time to explain.

The point I was actually at with that comment was about the ubiquity of a handful of companies on the internet.

That probably sounds like I'm need of an explanation about Cloudflare's reputation and what a ddos is. Please don't :)
You boil water from the neutrons/heat it creates.
This seems like a false equivalence. Trans people aren't trying to tell cis people that their physical bodies aren't allowed to matter to them, nor to invalidate cis people's gender or force them to be treated as another gender.
BitTorrent 2.0 is not recent, no.

No. Its not. Do anything with photos and color and try to do anything outside of platforms and its worse.

I've seen that around. Doesn't yummly require you to install their app to see the actual steps? That was a deal breaker for me. I hate websites that have a page then arbitrarily block content unless you get their app.
Sounds tricky and I hope you manage to find a solution that satisfies all parties. All I would say to each of them (in a round table discussion) is that as Founder you are happy with all (including yourself) receiving an equal share as you consider each of them to have been a crucial part of the success. By implying that you could have asked for a greater share but didn't it may help to sooth the greedy $$$ signs that appear to be about to rip your as of yet to be launched company apart.

Good luck & chalk this issue as a Life Lesson. Money, Friends, Co-Founders. Pick two and never mix all three, especially without anything in writing. Friendships go sour all the time, especially when money is involved.

If all else fails, try to see if you can find a local mediation service which is both a lot cheaper than sitting in a law office as the clock and bill runs up and also often a skilled mediator may be able to word things in a way that all sides can see what a fair and equitable solution might be. Good luck.

I'm extremely skeptical of bootcamps, especially after learning that some of the TA's at Lambda are hired to help with teaching as little as two months into the program as students[0].

Yes and unfortunately thats the humanities education that most students get. How to game the system through rote memorization in order to get a high GPA so they can get into grad school.

Sure there are exceptions to the rule, just like how there are people who have contributed greatly to the humanities without stepping foot in a degree granting institution.

It wouldn't surprise me if mask wearing did become pretty common place after this. I think some people view it as such a minor inconvenience that it would be worth it to wear during flu season.
Part of educational development has to include the realization that your instructors themselves have individual biases. To expect educators to be completely even handed and bias free is unrealistic.
It depends on circumstances. In some places and times, they really are the only practically-available option.
Then why do jobs say "BACHELORS DEGREE REQUIRED"
Meh, I expected this was true. However, after 6(?) years of maintaining a moderately popular project (~10k stars), it hasn't amounted to much real external value. It has never come up in interviews, it has never led to any job offers, it's mostly just a thing I work on for free which people happen to like.

Which is too bad. I want money!

My point is more that people seem to no longer consider war even a possible scenario. As such the weakening on the EU is not seen as a huge problem by many, because as we all know Europe is not at all historically prone to spontaneously bursting into flames.

In a way your comment which, if I read it correctly, implies "surely you don't think that the rise of nationalism could lead to wars" kind of proves my point. It totally could, and I'd add fairly easily. The peace we have is not as solid as it may seem, especially with dwindling resources and the rise of new superpowers in the East.

The temperature at the center of the sun is about 15million kelvin. The plasma temperature of a fusion reactor is around ten times higher. Also, a rector uses deuterium–tritium (D–T) fusion, and the sun uses hydrogen fusion. D-T requires less confinement and is more energetically favorable. If DT is like setting off a fire cracker then hydrogen fusion is like igniting a damp log.

>> fuel-powered aircraft will shed half their takeoff weight during flight.

While that is true of jets optimized for altitude, small piston aircraft (cessnas) do not burn nearly that much fuel on takeoff. Small aircraft can generally do a dozen or more takeoff/landing cycles on a single tank.
Sia is a decentralization first protocol. We believe strongly that the biggest advantage is an immunity to de-platforming and a commitment to uncompromisingly open protocol.

Crypto is the only means of payment I am aware of that does not have a centralized middleman with the power to deny a transaction.

Decentralization aside, there are efficiency gains as well. Every transaction on the Sia network is point-to-point, and in some cases we've had nodes that average more than 1 million discreet transactions per day for over a month. The total cost of doing that was something like $100 (including the cost of all the resources bought with those millions of transactions), I struggle to imagine a traditional payment system providing that kind of value.

There's also a lot more flexibility to innovate. For example, every single one of our payments is accompanied by a cryptographic proof that the accompanying storage or computation (not many people know, but the Sia network does support a limited form of computation) action was completed correctly. The payment and computation are fundamentally/cryptographically tied together in way that we could not reasonably achieve on a traditional payment system.

You're correct, that's a good ballpark for the average heat generation rate in the sun. However, 99% of heat generation in the sun occurs in the core (approximately the center 25% by radius) and this area is much more energy dense. Further, fusion reactors could achieve an even higher volumetric heat generation rate then the sun's core does.

To collect energy, heat would be transferred to a working fluid (e.g., molten salt) by exposing that fluid to the hot plasma. Then the working fluid would be used to boil water and spin a turbine.

What if the palm recognition is done without the person's knowledge via camera? Fingerprinting can already be done at a distance. Here's a story about it below from back in 2011.

What if the technology is built into door handles or other objects that require active use?

As soon as there is an incentive to scan people's palms, technology will be implemented or created to do so. However, Amazon has no incentive to let the public know if there's evidence of multiple people with indistinguishable palms, the rate of false identifications, or other shortcomings of the software.

High temperature superconductors provide more stable resistance-free conduction than traditional superconductors. If both are cooled to liquid helium temperatures, that increased stability translates to being able to sustain a higher magnetic field. Higher magnetic fields provide tighter plasma confinement and higher density, which allows for much smaller fusion reactors.
"The biggest advantage of JSON and YAML" should be put in a context of, "when working as a programmer with config files".

When we designed XML, we were working on things like a million pages of Unix documentation, or the flight manuals for aircraft, or research journal articles, or transcriptions of inscriptions found on fragments of ancient Greek pottery - lots of small similar documents, or very complex documents.

XML lets people who are not primarily programmers do sophisticated text processing and information design without depending on outside resources.

People who complain about XML being brittle are saying they want a system that forgives syntax errors, in the same way that JavaScript... doesn't... or that JAVA... doesn't... or that C... doesn't...or that Python... doesn't.

XML is unbeaten for the things it's good at. It was (still is, often) a problem that people used if in places where it wasn't so good. But that doesn't make it bad - it means you need to understand where it's good and where it isn't.
Read tracking is very useful when you deal with people who don't check their email. I know some old people who "got hacked", and as a result they are scared of email and won't check it unless called and told of something important. (emailing semi-private pictures and directions is often useful)

"hemorrhaging", like "abuse" is very vague language. I don't like condemning people based on this. It seems like a slippery slope.

Again, if you can point out a particular accusation in that article you feel deserves complete condemnation and the type of upheaval we are seeing, please point it out. I'd like to learn.

Otherwise, I'll continue to see this as a failed Navy Seal complaining about how tough it is to become a Navy Seal without understanding that the difficulty is built into the concept of why it's elite. If it was easy, there'd be no status associated to it.
