Ah got it. So I by sharding my investment into several different different targeted funds (with auto-rebalancing) avoid that issue.... I think.
Index funds can and generally should skip Berkshire Hathaway class A and just buy class B stocks without issue. It’s meaningless in this context.

The SP500 has a long tail 150M on a 20B dollar company, which is the median, is 0.75% per day that’s quite a bit of motion normally but you expect volatility to go up on a major sell off.

Anyway, if 1% of all money is removed from index funds on the same day whatever caused that is also going to cause the market is going to crash and crash hard. It would take something like an outbreak of Ebola in NYC to get that kind of a reaction.
TFA in two sentences (quote):

* Federal regulation of the aircraft has been slow to catch up, and is holding back many businesses from expanding.

> The build system issue isn't inherent to Rust or to large organizations.

That may be true, but even the big boys can't converge, and they all have their own build systems.

Attempting to add/remove features from cargo/rust when even the big companies can't agree as to what is most important in a build system seems like a path to disaster.

The big boys aren't always right (see: Gradle/Groovy).
Didn't see this Michael Moore video [1] until after the election, but it pretty well describes why I voted for him. I'm doing pretty well, but I have a blue collar background, and the people I grew up around weren't.

Didn't really figure he'd win, but my dad had died earlier in the year, and I figured he would have voted Trump, so I did it for him.

Wasn't really a "burn it to the ground" thing in a literal sense. Basically what the end of the video clip says: "It's going to be a big Fuck You to the establishment. And it will feel good."

And it did.

That's arguable. What's not arguable is that every OCaml compiler runs circles around GHC and scalac in terms of compilation speed. If you like not waiting for the compiler, then you should like OCaml.

The doctrine of laches, which is probably what you're thinking of, isn't typically available as a defense to copyright infringement suits -- see https://en.wikipedia.org/wiki/Petrella_v._Metro-Goldwyn-Maye.... There is, however, a 3-year statute of limitations on such suits.
So exciting to see. What does society look like when science starts investigating consciousness with a more eastern philosophy lens?
Very good point and you might be right, but that said perhaps at least your initial audience is going to skew more towards those who are already informed and have opinions on the matter, so it might be something better for later?

That aside, very cool concept and I'll come back and check it out more tomorrow (late here). I find any effort to evolve social media pretty interesting, actually tried (and failed) with an idea in this space myself a couple of years back. It's hard and I hope you succeed. Also noticed from browsing the topics you're doing startup school - me too (Box CI) - good luck with everything!
The point of the article for me is that all of this capital in one place is bad for contagion, and there’s no backstop to even small fluctuations downward / sell-offs that will end up zeroing out the wealth of most index investors. In that way it resembles all the capital in CDOs - but this time instead of being held by banks that can get bailed out it’s being held by individuals. Woof.

Bottom line - they look low risk until they’re absolutely not low risk because of these properties.

As an average investor I’d say diversify is still a good strategy. Don’t just do US Market index funds. Global stocks, bonds, and other small-cap stock collections might help hedge risk of large-caps going bust. Most passive-style funds also have these options. Not an active investor. Just a dude playing a dude disguised as another dude. This is not investment advice.
Every manufacturer needs a good revenue source. Unless you are a manufacturer that is making mass market cars like Honda and Toyota, you need to create cars that people will buy if you want to continue making your niche sports cars.

when the Cayenne was introduced, Porsche was ridiculed for making such a big, ugly car compared to their 911s but look how popular they are now.

Manufacturers don't make cars just for the hell of it. They make cars that the market demands, even if it's to the disgust of car enthusiasts.

The right to bear arms arrived to the United States via English common law. It existed in English common law for the purpose of self-defense, resistance against oppression, and to assist the defense of the realm.

Whether or not Madison (or Washington or whoever) changed his mind at some point does not change the fact that this is the purpose of the Second Amendment. No other laws (like the ones you cited) change this fact, nor does the Civil War.

You can argue that this interpretation is obsolete, but it's the interpretation that was predominant when the Constitution was ratified. Denying that is ahistorical.

> bind:group is not a "special string" but simply part of the API

Right, but the difference is in the API design. React gives you a small set of tools to implement whatever functionality you need. Svelte gives you specially-crafted tools which to handle specific scenarios. Svelte gives you a command to bind input groups to a stateful value, React gives you the tools to do it yourself. The difference is subtle but experience has lead me to vastly prefer the latter, mostly because you're less reliant on the framework designer getting everything "right".

Here's a good talk which helps explain the difference: https://2014.jsconf.eu/speakers/sebastian-markbage-minimal-a...
I believe they're still object pointers in CPython, they're just ordinary singletons; in other implementations, they aren't even singletons. Python's object model doesn't have primitives. Adding special rules around them would significantly complicate the language as well as limit the implementors' ability to fiddle with the ranges of pre-allocated instances, for minimal benefit.
This is a good distinction and absolutely right. The problem comes when people substitute good passwords for 2fa resets via phone. The problem with that is that the majority of usage now comes from the phone, so it's not really a second factor if you lose your phone. It's a complex problem that depends on the situation and really too complex to make a matrix of when it's ok for your average Joe. Passwords suck, and we still use them, because as a general rule, it's the best thing we have.
There's some really sound ideas in six-sigma as well as the other practices that evolved from manufacturing like Lean, Kanban, TQM, etc.

These approaches work, for real.

The problems start when they become excessively dogmatic, or as some say cargo-cultish. These systems are intended to help people solve problems in an orderly way, they're not a replacement for common-sense judgement, and original thinking (which, <gasp>, is STILL NEEDED).

Sadly, the personality types that tend to go into supply-chain and manufacturing (and that's where I happen to work) tend to be frequented by rigid-thinkers who crave process and prescriptive "checklist" approaches. Whatever new thing these people take up, it's eventually ends up as a turgid mess of dogma.
Conflating a rich family's claim to their medieval land holdings with the above mentioned struggles is totally flippant and disrespectful.

I wonder if we could ever get to the point where it would be a 100% machine vs machine war because the battlefield would be too dangerous for any humans? Humans would be more like puppet masters. The other question is could it ever get to that since the goal of a war is to stop the human opposition so the point is to always chace the human controllers?

If we ever got to the point where only machines fought that would make an interesting future. This is where SciFi writers could really enlighten us on what that future might look like.

I agree, you have a very neutral American accent, not much like a New Yorker at all. Other things I noticed include that you are indeed pronouncing each word very clearly, but also that you're speaking a bit more slowly than I would consider a typical speech rate (though not necessarily slower than the average Youtube video). In this video, you're also speaking at a bit higher pitch than a typical male voice, which I think further aids clarity because "sharper" syllables come out very clearly instead of being muddled like they are in very deep voices.

That said, I couldn't comprehend you well at all at 2x speed (using the Youtube controls). This might have just been to distortion caused by the Youtube player on my computer, I'm not sure. At 1.75x you were still very clear, though I suspect at that rate I would find myself pausing the video now and then to think about what you were saying.
I know that I'm not interested in "compromising" with the ad-tech industry. They've been spending too much time and money attacking my defenses against their terrible practices for me to treat them as anything but an attacker.

I normally don't admit to it, but I've become less fearful of the backlash lately.

Current plan is to vote for him in 2020. Worst case I will abstain from voting for President.

The economy is still on fire as much as it's ever been in the midwest. Can't complain there.

The trade war is unfortunate, but the alternative is to bend over and take it from China. Everyone agrees that they don't play fair. So the options are to do something about it, or to just let them keep on. My family has a manufacturing background, so all the offshoring is sort of personal.

The racial crap isn't nearly as much of an issue as the media likes to make it. It makes for good ratings, though.

Basically I'm hedging my bets on at worst I think the government should be robust enough not to be brought down by one bad leader. And if it is, then maybe we deserved to fall. Plus from my perspective he's not doing all that bad.
>> I wonder if being on Facebook reduces your motivation to build new friendships (it does take some work) since it allows you (with little effort) to maintain some form of very limited remote relationship?

Or maybe it has been tried before, and people saw what an utter disaster it was (the prohibition era). To which you might say that the war on drugs has been a similar disaster, and I will fully agree with you on this.

accounting software is used for formal bookkeeping, but i don't think it categorizes in this way.

> If your goal is to benefit the poor, and you have a system that does so, you should be happy.

Problem is these benefits are superficial. On one hand you get cell phones and cheap flights, on the other rivers of plastic and land devastated by mining.

And it isn't even worth it, because a large part of the profit inevitably goes to those responsible for this devastation, so wealth is actually extracted from these places.

> Yes, and unfortunately mitigating climate change is directly at odds with alleviating their poverty.

It is in this system only, which allows it in the name of profits for the powerful.

Lithium-ion battery construction has been constantly changing since its invention in the 90s, but the basics have been the same rather consistently. The batteries are fairly universally "non-toxic" assortments of "light" metals and salts in organic (Carbon-based) solvents. (Lithium itself is Atomic Number 3 on the periodic table; it's an incredibly common light metal. Cobalt and Nickel in the high-20s are generally the highest atomic numbers you see in any of the battery formulas, and many of the compounds are "organic". Neither of which is a direct link between atomic number and organic nature to toxicity of the final compounds using it, see ethanol, but as a first order approximation it's an okay start.)

None of the big battery manufacturers (LG Chem and Panasonic are too other huge manufacturers to compare to Tesla for instance) are doing much at all different from Tesla.

They all have methodologies. The pilot's checklist that was already mentioned is just one. For doctors you have different paths of treatment that can be standardized for years, then undergo major changes when new information is discovered. With lawyers it depends on what they do. New approaches to cases, new discovery methods, everything is a process and everything can be improved.

Software development attracts these things because software development isn't as firmly entrenched in tradition as doctors or lawyers are. There are way more people that are open to implementing ways of accomplishing tasks that are more open and efficient than there ever could be in most other realms.

It's intellectual property. So, yes you can apply property rights to it.

Private investment is absolutely where the money is these days. Look at how the media claims an IPO that doesn't pop 30% or more on day one is a "failure." No one who actually contributed to that company's value benefits from that pop, and best case scenario is really to either have the IPO be flat or even go down a little. But those elite that buy their way to the front of the line demand to have that 30% pop for contributing nothing.

I'll just point out there's the argument about market makers and underwriting and blah blah blah. If that's such an issue just price that into the underwriter fees to begin with. No reason the public markets should lose out on a 30% gain to people that didn't actually take a risk and invest early in the company, and only intend to hold the stock for 8 hours at most.
"Advertising is unquestionably here to stay"
Often interesting hearing people use "unquestionably" meaning that no one believes differently, rather than a more apt word meaning you personally feel strongly about a certain view point and and don't know other people's point of view and not concerned with it. You also mentioned you find it hard to believe people would prefer irrelevant ads over relevant ads, but of course many people do (since if one has irrelevant ads they will be less likely to engage with them making them less profitable for the advertiser and in the long run making that form of advertising less viable), so sounds like you may want to ask more questions to learn other people's views so that you may either update your views or be able to make stronger arguments for your own. IMHO.

I didn't see anything in the parent comment about assassination, but given the topic: Yes, when governments were effectively embodied by one single person invested with something approaching absolute power, bumping off that person would change the situation. Of course it often plunged the kingdom into some type of crisis until the succession was decided and a new monarch/king/whatever was installed. That's still the case in some countries, like what happened in Iraq w/ Saddam Hussein (yes, it was more complicated than that, I know) But in other countries that have some flavor of democracy, bumping off the person in charge is not really a path to changing the social/economic order. The power structures go way beyond a single individual, and continuity is fairly well preserved.
