Dark matter is predicted at every level of astrophysics. It's not just "hey, galaxies look weird".

The amount of visible matter only accounts for 4% of the cosmic microwave background.

The CMB is extremely smooth, but visible matter is highly clumped up. This can only be explained by a huge amount of matter that doesn't clump up ie non-baryonic.

The ratio of deuterium to hydrogen rises based on the density, since there's more pressure from gravity. There's way more deuterium than can be explained by visible matter, so there must be some extra compression happening.

Galaxies have more kinetic energy than they can have given their visible matter and how fast it's moving. This implies a huge amount of invisible mass.

Gravitational lensing around the edges of galaxy clusters indicates a halo of invisible mass.

Colliding galactic clusters show their mass splits into two parts: one that clumps up into a bright, dense blob, and another that has much higher inertia and continues past the bright blob as if it didn't interact with it in any way besides gravity.

We can map variations in empty space where there is more mass than is expected, in a way that can't be explained by a self-consistent theory of gravity but can be explained by invisible mass.

Dark matter as a theory hasn't changed for 80 years and every single one of these discrepancies is solved exactly by using the measurements of dark matter that already existed. They all agree with each other perfectly. There is no theory that even competes with dark matter. Nobody has come up with another idea that explains all of those or even most of those problems.
I explicitly avoided mentioning the S&P500. Why did you bring it up? It makes your point nicely but I'm not talking about the S&P500 or the R2k as examples where front running of any significance is happening. The index additions/deletions in the Total Market indices happen at the margins: micro-cap stocks (and IPOs). Hard to argue much happens of any effect with micro-cap stocks.

I don't necessarily disagree with you on the S&P500 or R2k, but it's much harder to make the same argument for total market indices.

Please justify how you are saying the market returns understate potential market returns. If it is not an index you are using, what is it?

> Why would the timing of the reconstitution have anything to do with why this is possible or not?

Because they have similar returns and add/remove stocks at different times. If Vanguard's total market fund adds a stock after Fidelity's, then any jump ("front-running") in share price due to Vanguard's purchases would be captured in a higher return for Fidelity since it already owned the shares.
Agreed--many domain-specific searches are already much better done by Google competitors, especially Amazon. I go straight there for information on pretty much anything I might buy. Likewise Yelp for restaurant and other local services.

This is all the more true on mobile, where the search is meant to initiate an action: buy something, make a reservation. Being able to complete a circuit in one place gives competitors in some domains a powerful advantage over Google.

consumer internet privacy and security (think barracuda for the home market -- above and beyond a standard router/firewall possibly with active L7 features)

consumer and enterprise storage management (they literally can't even make enough ssd's right now, people and companies are hoarding data and can't manage it effectively or reliably)

rural and wilderness area wireless internet (people will start moving out of cities again and will want the same > 50 megabit low latency service).
Yep, and people get downvoted for pointing it out...
Most people - 90%+ didn't have access to a free internet until early 2000's (for practical purposes), encryption was hardly ever used by private citizens until GSM came in in the 80's, and then it was totally back doored - by law and standard.

> store them securely in a password manager and use different passwords for each account​

You are about the 2% of the tech crowd (i.e, bay area software/data people). The vast majority of engineers do not use a password manager, let alone the entire US populace.

You severely overestimate the amount the average person cares about password security.
A.) God waved his finger, and the universe sprang into existence, along with a bunch of mythology.

lib you linked is a bit crazy, it uses setInterval to guess when a css is properly loaded/applied and delays running dependent code

imho this is sufficient:

define('css', function () {
return {
load: function (name, parentRequire, onload, config) {
console.log('loading css ' + name);
const link = document.createElement('link');
link.type = 'text/css';
link.rel = 'stylesheet';
link.href = name + '.css';
document.getElementsByTagName('head')[0].appendChild(link);
setTimeout(onload, 0);
}
};
});

usage:

require(['lib/js/jquery-ui.min', 'css!lib/css/jquery-ui.min'], function () {
// jquery-ui magic goes here
});

I agree the title that it's bad as well. It eventually creates password fatigue and users are less likely to expend mental effort picking good passwords if they know those passwords are going to be thrown away in 90 days.

Really the only thing I recommend anymore is a good password managers. Use one very strong password, perhaps changed every 2-3 years if you feel the need, to unlock one or more secure private keys with which all your passwords have been encrypted.

The great thing about good password managers that use asymmetric cryptography is that my password is not really the weakest link. If you have access to my hardware, then guessing my password will potentially help you, but otherwise you'll have to break my pgp key (assuming you can also get access to the encrypted password store).

At that point I don't really care what your rotation policy is. I can generate a new password every 90 days with no real fatigue.
PC/XT hard disks read at 125KB/s, and floppy disks from 15 to 50KB/s. And it was slower to decompress than to read. 8086 @8MHz RAM bandwidth was about 1200KB/s, so data compression algorithms based on dictionary (LZ77, LZW) were crazy slow. So the LZ4 decompression time achieved is impressive.
Here is a paper that discusses a possibility that the General Relativity alone can be enough to explain the observed dynamics of galaxies:

https://arxiv.org/abs/0712.0019

From the paper:

we are witnessing here the power of the nonlinearities inherent in general relativity in the context of weak gravity to effect very significant changes relative to the results expected on the basis of Newtonian theory. It suggests that hitherto unexplained astrophysical phenomena
be re-considered on the basis of the application of general relativity to weak-field gravity.
Do people in the UK see the police as adversarial, like they do in the US?

No. Ordinary police officers that you might meet day to day are mostly just decent people who want to be approachable and have good relations with their local communities. The collective organisations that represent those officers within senior management and to the wider government often defend these principles. Policing by consent remains the foundation of our system, at least for now.

I fear this will change over time, though, not because of the generally decent people working on the front lines in policing, but because of the authoritarian measures pushed through by their government masters and the bias in how they are used, the perception that if something does go seriously wrong then the police involved will not be held accountable, and probably also some element of having a lot of US TV shows and films where we see a theatrical portrayal of a very different kind of relationship.

He is going to a conference obviously, but how does he prove that his intent is "purely non-immigrant" besides that? I mean, it seems to me this could be used to deny anyone entry since you can't very well prove it (I think) if it is not enough that you say that you are not trying to work or immigrate.

Or am I misunderstanding something?
I think the keyword is "periodically". They're not saying not to change passwords for any reason; they're just saying not to do it solely because the password has been in use for some fixed amount of time. That recommendation applies to users as well as to services setting password policy.

> I've seen versions that would do just fine with the separated part mixed in. (They're not just with Granola.)

My guess is that, if you're going to be offering a version with granola, you're going to be designing/fabricating packaging with a separate mix-in container anyway; and since you have to have that package, it's just easier/cheaper to re-use it for other mix-ins that don't technically need to be separate than it would be to come up with another package just for them.
Still too expensive. Instead of biasing your user studies with big companies that already use your product, you should listen to the greater population of potential users. But hey, that's startup 101 and I don't expect you to know that.
Google Maps and other map APIs are great for visuals, routes and ETAs. Where they lack is generating a battery efficient accurate location stream and mapping that to your app's workflow. Plus, map APIs are priced on the basis of number of API calls or views, both of which can lead to unpredictable cost for such a feature.

Most people are terrible at predicting the future in this way. Some of the most accurate predictions sound like (or are) jokes at the time, like when JK Rowling was writing her first book as basically a "welfare mom." She did a lot of the writing while her baby napped at some eatery owned by friends/relatives. She would make jokes to the effect of "When my book gets famous, it will put your place on the map!" That basically all came true, from the book being famous to it making the place she wrote it famous too.

But when you go back historically, predictions of what life would be like "now" all left out the world changing invention of computers and internet.

There is a scene in the movie "The Graduate" where he is at a party and everyone is telling him what he should go into as his career because it will be big in the future. One person tells him "Plastics!" This was a joke at the time, a ridiculous statement. Years later, the plastics industry used that bit in a TV commercial.

If you really, sincerely believe "The Future is all about X industry," you aren't telling people that on the internet. You are quietly behind the scenes buying more shares in X or getting training to work in X or otherwise trying to make sure you are the firstest with the mostest in X.
You're now excusing abusive crappy behaviour towards people by quoting other terrible abusive behaviour. Alternatively, you're doing the same by quoting bureaucracy and forgetting that someone wrote those inhuman rules.

I might be harsh, but this kind of "it's procedure, we're not budging!" defense was used by government officials in our previous socialist government to treat people like crap. And both the rules and petty beaurocrats interpreting them in worst way possible were the cause of a lot misery.

No need to defend that.
It's very common concept.
I think you only grok half the story here. You're correct - black holes are not a popular candidate for dark matter, for reasons you described. But this article is not about candidates for dark matter, it's about removing dark matter from the equation entirely. If I understand correctly, black holes here are given as an explanation for isolated examples of strange gravitational lensing effects.

The fear of hydrogen lifting gas is overblown. The Hindenburg burned largely because the canvas was painted with highly flammable paint that was chemically similar to rocket fuel.

We regularly fly in airplanes full of fuel, and if they catch fire in flight the odds of any survivors is extremely poor.

Hot air balloons, with no hydrogen, catch fire now and then and everyone dies.
That's the Overton Window shifting. Not too long ago I recall everyone being horrified by a stratified net, where you had to add your name to a list somewhere to disable filtering. Now that's considered the better option?

Nearly half of Houston's 2017 valedictorians were once ESL students
From the article:

"In the Houston ISD, nearly half of this year's highest-ranking students once struggled to speak English, making them among the largest groups of non-native English speakers to be named valedictorians and salutatorians by the district since 2007. About 44 percent of Class of 2017 graduates were once English-language learners, the district reports."

"While Spanish speakers make up the bulk of English-language learners, there are about 100 different languages spoken by students and families in HISD."

> Consumers can choose with their wallet if they're so inclined...

You really don't understand how corporate capitalism works, do you. Good, healthy, "moral" food is expensive, and believe it or not, most people (at least most Americans) can't afford to pay $4.00 for a dozen eggs from chickens that have PhDs. It's a matter of scale. If millions of people don't make enough money for hippie chicken eggs, then they _actually cannot_ choose with their wallets. What is with the fucking Hacker News crowd and their delusional belief that people are making all of these free choices to buy the worst possible crap they can shovel into their bodies instead of being forced into it by jobs that don't pay enough and food companies that cut so many corners that they can get away with charging next to nothing for cheap, delicious garbage that's just going to make people addicted anyway?

> besides most of the 'horrible living condition' propaganda is aimed at the uneducated...

Have you ever _seen_ an industrial chicken farm in the United States (or any kind of industrial farm used for raising animals for meat)? It's not just one "horrible sad chicken" that had a genetic mutation. It's _thousands_ of chickens kept in the tiniest, filthiest, shittiest conditions imaginable because some rich executive wants a fourth Mercedes.

Wow, that sounds like a lazy shitty manager.

Every engineering team has problems they can't deal with on their own, either because it's out of scope, it's high-level organization, or whatever. A GOOD manager spends a significant chunk of their week ACTIVELY fixing problems. Not getting-the-fuck-out-of-the-way!! They should help clear the way. They should help fill gaps in the team, plan, or execution. Talk to other teams and see if everyone's on the same page. Make sure everyone agrees on priorities. Make sure your team's work integrates with what everyone else is doing. Be aware of everything going on around you (esp with other orgs, etc) so you know how it all fits together and your team doesn't waste time.

Don't just listen and nod during 1:1s and then give some off-the-cuff suggestions. Don't just "get out of the way". And you don't need nearly that much Air Cover when you're team is aligned with the rest of the company, so make sure THAT happens instead of trying to "protect" the folks that happen to report to you.

If a great team's manager can't point to what they ACTIVELY DID to get the team to success, they're disposable.
5 years out is not that hard, since it is basically which technologies that are either just out, or coming out soon will be successful. 10 years is more challenging, 20 impossible.
What isn't wrong with rejecting someone from visiting a conference he got scholarship from?

I mean, you can quote "security", "not enough paperwork", "he didn't smell right and a suit decided to reject him"... but in software we usually call that a bug - someone should be able to visit a conference but couldn't due to broken process. And there's A LOT wrong with making people miserable over paperwork. It has to serve people not enslave them.

Businesses for whom location tracking is critical process component and not a good to have such as logistic companies or lets say food/medicine delivery companies who also already have an app deployed with their end agents, the additional cost for them to get location tracking and reporting integrated in their mobile apps is trivial and also there is no technical moat as is there in lets say messaging or SMS APIs ( like Twilio). Either I don't understand your customer set, or problem you are solving is simply not big enough. You are trying to do to location tracking what twilio did to messaging, but reality is location tracking as a service doesn't make a very solid business case here. But best of luck :)
> I'm not sure it's survivorship bias.

I'm referring to good ideas being underfunded for a time. Only good ideas survive. Bad ideas obviously don't get to a point where they turn into something accepted and widely applicable (I'm sure there's a countercase or two...)

So only the good survive. Does that mean we need to fund across the board? That's just not feasible, so we have some good ideas that go unfunded, but a whole lot of bad ideas that do not.

> manage a portfolio of research and (e.g.) hedge across multiple hypotheses.

I see this happening in well funded labs. Taking a bit of money from here and some from there in things that are novel, but ethically related enough to be able to be justified.

But the ethics involved makes this dangerous.

You bring up good points.
Yes, I am arguing that there are far too many sociopaths, and that only fear of consequences keeps them in line. Whether that's in meatspace, or online.
