> the monopoly on violence the government holds

People keep complaining about the "government monopoly on violence." What other group would you prefer to have a monopoly on violence? If the government doesn't enforce a monopoly, then invariably someone else will, in the process becoming the new government; or else two or more groups will actively dispute it, a condition commonly known as "war."

Actually one of the talking points is that no one will talk about lead levels before they switched the water from Detroit to Flint river. But its not as bad as it is now obviously. . . Does building this 'coat' back up work? How long does that take?
> Pray tell how does one measure demand elasticity[0]?

The phrase "during CPI calculation" should be the key to understanding here. CPI tells you how much prices have gone up or down generally, by just sending a bunch of secret-shoppers around to measure a bunch of prices.

Knowing the treasury's current bond interest rates, the current exchange rate, and Core CPI, you can derive economy-wide aggregate demand—which is the point of the whole exercise. You can then look at any given good's economy-wide demand (i.e. the same formula, where Core CPI is calculated in terms of just that one good) relative to total demand as a time series, take their co-variance, and that's the good's demand-elasticity. (All the numbers are public at every step; there's no real way to fudge them.)

> Would tampons be covered by UBFS? Let's say then we allow for UBFS to cover female menstrual products. Would cups then be covered? Why or why not?

Again: you plug in the demand-elasticity formula and get an answer. No politics, just cold automated logic. Female menstrual products as a category are very likely to be calculated to be inelastic.

Now, how that breaks down to individual items within the category is something I didn't define. As a raw guess, the government could define base inelastic-value for the category, which would apply as a sort of rebate to all the items in that category. Any individual item's price should, after this "rebate", reflect exactly and only its additional elastic demand—making the "premium" products cost some number of nicety-dollars, while the "economy" products in that class cost "nothing" in nicety-dollar terms. (The real key there is the creation of a law preventing companies from increasing their prices in response to this—because, without market manipulation, of course prices would rise to reflect all the same competitive demand as before, plus the extra "free" votes each person got. The law would just need to force companies receiving necessity-dollars to price according to demand in an alternate world where demand was exactly [the amount of inelastic-demand] lower.)

> one word: Arbitrage.

No reason to allow individuals to trade in necessities at all, which would nearly completely prevent arbitraging opportunities. (e.g. it's obvious enough that you shouldn't be able to rent your necessity-dollar-paid apartment out on AirBnB.) Consider anything paid for in necessity-dollars to be tainted and have no legal nicety-dollar value after that.
That's a really interesting idea, but another issue to consider is that a lot of food/housing could be considered "nicety" rather than necessity: sushi, craft beer, luxury penthouse apartments, etc. How would you decide how much of your mansion is covered by necessity money, and how much is nicety?

hmm, I think that describes something different. "the world's most indispensable company". google isn't that. not sure what is. maybe the big oil companies (collectively) are indispensable? that's kind of a shame really. no company should be indispensable.

to me though, google is clearly important, in a historical sense. they are building things that change the world. they also seem to care (at least pay lip service) to trying to change the world in a way that is a net positive for most people.
The point is that the entity given a monopoly on violence needs to be held to a higher standard than entities that aren't.
Linear algebra.

Things like constraint solvers, automata, Bayesian reasoning & other probability/stats topics, etc. may also come in handy, but the core is mostly applied linear algebra.

Also, math will help you understand machine learning algorithms, but if you want to be a practitioner, most of the hard work is in feature selection, data cleaning, backtesting, etc. These don't need a deep understanding of math so much as a deep understanding of your data - key skills there include graphing data; having an intuition for different statistical distributions; being able to build a webapp that lets you easily graph a candidate feature, drill into examples, and share the results with the rest of your team, and other very mundane tasks that are pretty basic software engineering with a stats focus.

However, has even that much been proven? We know eating fruits and vegetables is good for you, and we know that in vitro, antioxidants help prevent damage to cells from free radicals. But considering that experiments with antioxidant supplementation have failed, do we really know that it's the antioxidants in fruits and vegetables that make them good for you?

See my sibling comment: figure out how much inelastic demand there is for a good-category, rebate that amount off of all prices using necessity-dollar allocation, and then whatever's left over is the true nicety-dollar (i.e. elastic demand) cost.

One interesting effect of this is that if you calculated it per-market, then different goods would have different inelastic-demand floors in different markets. In e.g. Vancouver, where tiny one-bedroom detached homes can cost >$1mm, there'd be a pretty large necessity-dollar allocation for rent/mortgage. In Cleveland, where houses go for $65k, it'd be much lower.

You might not want this effect—you might want to incentivize people to move to cheaper markets instead. But the network-effect of cities is another of those things economic incentives just don't seem to work very well to treat.
But if you have a child company, wouldn't you expect to associate the parent company with a feminine gender before a masculine gender? That's what I am getting at. An organization has that "motherland" feel in some way.
This sounds like unnecessary complexity as well as something that could cause problems. I don't think there is a need to restrict people to necessities when paying them a minimal income, they'll do that themselves.

It is overly judgemental of what people living on a basic income are allowed to do, thus making living on only the basic income less viable. Your mother is dying and you need to fly to a different city to visit her? Nope sorry, long distance transit is a nicety. You want to take some time to switch careers? Sorry, books are a nicety. Have back trouble? Sorry a fancy chair is a nicety. You may say that those things could be necessities but a huge fraction of goods typically a 'nicety' can be a 'necessity' in the right circumstances. Better not to tie people's hands.

I think this adds a lot of complexity, cost and bureaucracy for a net loss in how effective the basic income is.

The Detroit urban area has been a disaster for a while. Flint had been getting lake water from Detroit. Detroit, bankrupt, wanted more money from Flint (also bankrupt). Flint was "forced" to switch to river water and yes they did not treat the pH.
I'm no expert, but I assume it takes long enough to where they are just going to have to replace all the lead pipes and fittings.

That talking point you mention could be true, or it could be a way for the state level government to dish it back to the local government. Who knows. To me it seems like the municipality screwed this up more than the state, but like I said it's virtually impossible to find an unbiased news source with the whole story; they both no doubt have a role. Even this very story is politically driven, it could be misleading in its urgency to drive clicks/narrative. Happens all the time with various things in the news (like the claim of x drug use among teens, etc.)

Hopefully there is a non-partisan investigation from the Federal level on the Flint fiasco.

I think the narrative comes from the cases where it's true - i.e. the really successful acquisitions and IPOs.

I think the issue is that overly optimistic companies (and probably some unscrupulous ones) estimate the likelihood of such an outcome to be greater than it is. But that doesn't mean that's never true (like it sounds like you found out).

As of today, what stops someone (regardless of their intentions) from building or making their own Stingray-like device?

Is it illegal for an 'average joe' to build or develop one of these? Or is it just super high difficulty, ie the protocols just aren't published or [easily] reverse-engineered? Or right now is it just the illegality of call recording entirely that is "preventing" it's use?

Pretty sure I watched a conference talk that demoed a functional one that included pass-thru [to prevent suspicion/non-functional devices] to the real cell tower IIRC).

I'm just curious because obviously this isn't something you want just anyone to be able to build & deploy -- so much potential for abuse, anything from basic identity theft to serious securities fraud, and much more quickly becomes a very serious & probable threat once these become even just slightly more "mainstream" for the public / criminals / mafia / etc...

32 years is quite a long time in computing terms!

Both the computing tech and raytracing/graphics theory and algorithms have changed significantly over that time, with better algorithms and much more powerful computing resources allowing more brute-force/accurate stuff to be more practically done.

Writing a raytracer/renderer is also rather addictive, and it's quite cool writing something which produces something else (as is writing compilers).
That is interesting - one of the postulated prerequisites for sociality in insects is haplo-diploidy, where one gender is haploid and the other is diploid, like it happens in bees and ants.

This leads to the curious outcome where sisters are closer related to their sisters than to their daughters: https://en.wikipedia.org/wiki/Haplodiploidy#Relatedness_rati...

I assume these spiders are all diploid?

Wikipedia says that part of the social behaviors in these spiders is that they don't discriminate towards foreign offspring. I'm reminded of Argentine super-colonies, which are ant species which form enormous colonies stretching several hundred kilometers but which may or may not be genetically distinct - one hypothesis as to why they cooperate and not fight is this:

>the reason ants in the Mediterranean don't fight is that, although they are genetically diverse, they have lost the diversity in the genes that are involved in recognition and thus don't recognize each other as different.

Source, 2004: http://news.stanford.edu/news/2004/april7/antstudies-47.html

Wonder whether these spiders have the same thing!

> I wonder to what extent I'm stressing myself out over a very uncommon occurrence.

Probably too much. Modern medicine actually does work for the vast majority of people--"Hospital does 42 surgeries today--all of them went just fine" never gets reported. However, humans are biological organisms with lots of variations. Exceptions always exist.

If you've gone under more than once without complications, you're probably mostly in the clear. It means that a whole host of things that can go wrong have already been screened against. One of the big ones is having a problem with your pseudocholinesterase but no family history to tip off the anesthesiologist that this might be an issue (I think they screen for this now).

As you point out, the issue is also "if available". In your case, it's what needs to be done, so don't stress over it. The complications of NOT doing it are far worse for you, as you point out. However, too many people just go "put me out" without the idea that, yes, complications do occur and, really, less invasive is almost always better.

Serious question: is this not seriously illegal?
UBI isn't supposed to fix the problem of money mismanagement. If everyone was spending up to their means, that would be a success because the economy would be flourishing. If they were putting that money into savings, the experiment would be a failure. UBI is designed to solve for the future economy where human labor's value diminishes. In 20 years your brother's welding job may still be paying but whatever job you (or your children) do on a computer will likely be much better handled by AI. UBI is to bail you (and most of our economy) out, not necessarily your brother.

Okay.

So, this is a pretty heated debate :)

As someone kinda correctly identified, here is what happens:

Agencies are either directed by congress to make certain regulations, or more broadly delegated rulemaking authority.

They exercise that rulemaking authority through an administrative rulemaking and publishing process that ends up with stuff in the CFR.

This part is simple.
You can find a parallel table GPO/etc conveniently publishes, of which USC code gave rulemaking authority for which CFR parts here:
https://www.gpo.gov/help/parallel_table.pdf

I honestly feel bad for the person who has to keep that up to date.

Now, the larger question that was asked - can you be sentenced to jail for violating a CFR.
The answer is "yes". You will likely be charged with some USC violation, whose regulations/etc are interpreted through some CFR regulations.

a good example of a law that has criminal penalties and CFR regulations is HIPAA. See the aptly titled "who goes to jail" - http://www.ehcca.com/presentations/HIPAA3/malone_2.pdf

Notice the regulations are in the CFR, violations of them are explicitly punishable under USC (IE "knowingly and in violation of the regulation ...."). With criminal penalties.

Now, this is not the same as the related question of "can you be sentenced to jail by the FCC for violating the CFR. The answer to this is "well, maybe".

The courts these agencies set up, and their administrative law judges, tribunals, whatever, are generally known as article I courts.

The current state of the law on article I courts is kind of a mess. In general, they have some power, but if it involves deprivation of life liberty or property, it must at a minimum meet various requirements (including being reviewable by a standard article III court).

Honestly, this is a super-complex and super-esoteric topic to get into on hacker news.

So yeah, you should worry about the CFR, but you maybe shouldn't worry the FCC will throw you in jail. It'll be federal prosecutors instead :)
As someone who spends a lot on Google and Facebook ads - this guy got it right.
If you define HFTs as passive spread/rebate-capturing single instrument market-makers, then yes, but many prop HFTs operate a "hybrid" model where they sometimes cross the spread to flatten their book, or cross if an arbitrage presents itself.

Also sometimes very poor counties, think Alabama, Kentucky, Wa Va, will attract companies who need to dispose of pollutants but at a price, in order to extract revenue for an otherwise unproductive, resource-poor county. That's to say, they provide landfill space at a relatively low price. It's unfortunate, but it happens.[1]

We could call it the Universal Black Market Dollar! Are you unfamiliar with the process of trading food stamps for money that already exists?
Wow, that sentiment rings incredibly true. While the specific use cases may be a bit different, many companies are similarly fed up with the legacy ATS products for internal recruiting. Every time we encounter a recruiter or a hiring manager using a spreadsheet we ask ourselves why. We take design very seriously at Lever, and the workarounds extreme users do are some of the most insightful ways to learn what the real needs are.
But we know that these same corporations may be legally obliged, secretly compelled or financially incentivized to give or sell the information they have about you to the government. And if the government cannot get hold of the data through these means, they can simply steal it from the privately owned data centres where it has all been so conveniently aggregrated. Especially since Snowden we have seen that private corporations function as a funnel through which intelligence agencies amass data on private individuals.
> You need to protect your state by communicating with channels or using a lock.

But what are you protecting? Setting a value will not cause a map rebalance, and so long as you are just setting a new value (not incrementing or like) it should be an atomic operation. Locking is really slow, and if you can find safe ways to avoid it, it can be a good thing.
