I can't agree. I did not find state revenue numbers at your link, but I did find them:

Total state revenue is $930M (across all states):
https://factfinder.census.gov/faces/tableservices/jsf/pages/...

Federal revenue is $3180M:
https://www.nationalpriorities.org/budget-basics/federal-bud...

From your link, states spend approximately $1860M per year. According to the revenue numbers I've found that means that half of all money spent by states must be supplied by the federal government or by debt. That is certainly sufficient to account for the perverse incentives I've noted, since states unlike USG cannot print money to cover debts.

There is a slight discrepancy since my revenue numbers are from last year, but generally, I would not agree that your source contradicts my claim.

> "Language provides us with this tool to gain distance from our own experiences when we’re reflecting on our lives. And that’s really why it’s useful"

"What if we don't pay them at all?"

If someone says "here's a simple mergesort implementation. It requires unsafe in a few sports, for performance"[1] or even "you can implement a fairly normal mergesort, but oyu may want to use unsafe in areas A and B for speed", I view that differently than if someone says "you can access strings without confirming they are UTF-8 encoded with str::from_utf8_unchecked, but it requires unsafe".

One, has, for the most part a self contained implementation and is part of a very well known algorithm. Checking that the implementation doesn't have any obvious flaws may be sufficient.

The other has implications that far outlive the small suggested bit of code. Until you've correctly made sure that anything resulting from this call has been confirmed to conform to UTF-8, there is a risk in it's use in any number of string processing routines.

The article, to it's credit, does mention that problem with UTF-8 when working with it unchecked, albeit vaguely. What I don't think would have been sufficient for an article that aims to help people would be to say "it required unsafe" and leave it at that. That would be suggesting a routine for performance reasons without sufficiently addressing the real downsides.

Thus, my assertion, that simply noting that something requires unsafe is sufficient to denote in all cases the consequences of the suggestion, as I interpreted rabidferret comment to imply.

Another way of stating my argument is "when suggesting unsafe as a possible solution, it behooves you to mention any non-obvious consequences this specific suggestion might entail." That's a fairly uncontroversial view, in my eyes, so I'm not sure exactly why I've had to explain it four separate times now.

It does matter for preserving original timezone. An int is a data loss.
If the software converts to UTC it should be using the expected local timezone on the target date (4pm Tuesday), not the current timezone. So this will only be a problem if the TZ tables for the future are not correct (which happens, as noted in sibling comments, but is not as widespread as every DST event like your comment seems to imply).

Another particular interesting representation is Guibas and Stolfi's "quadedge" data structure from their 1985 paper at "Primitives for the manipulation of general subdivisions and the computation of Voronoi," source http://dl.acm.org/citation.cfm?doid=282918.282923 and pdf at http://www.sccg.sk/~samuelcik/dgs/quad_edge.pdf.

It really is an elegant use of some basic topology with impressive results, a full Voronoi/Delaunay linear-log time algorithm in less than a page of easily implementable pseudocode (once the data structure is written).
Yes, some of the attempts at a theory of quantum gravity indeed are hinting at a "quantum of space" around the Planck order of magnitude.

However, theories that assume a "fixed grid" sort of arrangement tend to run into issues. If space is quantized, the pattern is probably not the fixed rectangular sort, but something else instead. Perhaps the notion of space arises as a smooth approximation of some kind of graph of nodes and edges of some kind.

Source: Lee Smolin's books.

(So the search for the "quantum of space" is legit, it's just not likely to be fruitful very soon because of the scale involved. But someone's got to try it.)
True, but there arent many places that I can host my side projects for free with zero server maintenance like I can on App Engine. Its a trade off.
> It would serve to optimally satisfy demand...

Well, it would serve to optimize (or come close to doing so) some utility function, which might be labeled "satisfaction of demand". But who defines that utility function? Some central planner.

But how does that central planner know what I actually want? Yeah, I could tell them with my smartphone. That's going to tell them a pretty coarse approximation to what my actual desires are, though.

For example: Life Savers candy. People choose to buy the stuff. A roll of them costs, what, $1? But how many people are going to bother listing that on their phones? A whole lot fewer people than actually buy Life Savers, I bet.

[Edit: What's actually going to happen is that an element of politics is likely to creep into the definition of the utility function. "Oh, they shouldn't want that; they should want this instead."]
I know a few folks who did a six month bootcamp almost exactly three years ago. At present they are: two front end devs, three back end devs, two 'enterprise' (aka Java) devs, a dev evangelist, a devops, a stay at home dad, a currently job hunting, and an agile consultant.

I have two qualms about this claim: The first is purely economical. Does this not simply indicate that there is insufficient supply of electricity storage (ie batteries)?

The second is... wow, if excess supply of energy is a reason there are detractors to wind and solar, then maybe treating electricity as a market is totally misaligned with perpetuating sustainable human activity. Maybe we shouldn't do that.

Yes, exactly like regeneration. However it's a highly multifaceted problem to optimize. Batteries, capacitors, drivers, motors and drivetrains all have very picky efficiency regimes. Grease is very inefficient at low torques or high speeds, since it's shear-thinning and viscous. Motors have to have their voltage, current, field strength, size and a few other aspects all optimized. You run the gamut from metallurgy to fluid dynamics to chemistry to EM fields. It requires tons of high performance custom parts.

That said a few groups have done it. Heavily optimized drivetrains can be ~96% efficient at the right speed and torque. Extremely precise drivers can regen at 98%+. If you charge gently enough batteries can be 98%. 88.5% total efficiency. That's extremely good, enough to reduce power consumption by 8.7 times.

It's better than a human but not quite as good as an insulated spring.
(I work at Mixpanel)

Honestly you could probably write a quick pipeline to dump your json data into Mixpanel and then use JQL -- it would be a little hacky but if you have less than a few million rows it shouldn't be too much work (and would still be free at that volume).

Sounds like someone needs to have better planning and buy a few extra batteries.
Maybe central planning works better on big items than it does on little ones. Gorbachev decided that central planning wasn't working when he realized that the USSR could produce military hardware as well as the US, but couldn't supply toothpaste to its population.

> There are no evil people, there are only people who have been brought up in an environment where the actions they have taken are acceptable.

Funny, serial killers still exist and will continue existing, even though society has condemned that for a long, long time.

Yes, some people are born with their wires misshapen, just like there're people born deaf. What? Did you think that the brain was, somehow, our only organ that couldn't get messed up since birth?

So, are they or are they not born? You're contradicting yourself.

Yeah, you keep telling yourself that. A friend of mine (hailing from my latin american country) and the refugee crisis tell me otherwise. If so-called "hate speech" is banned openly, it just happens behind doors, using so-called "coded language".

> The 915 surviving and growing white supremacy hate groups, along with the 'alt-right'.

So do TERFs, the militant branch of BLM, AntiFa, etc. If we're going to judge by fringe groups, they just happen to be more visible every day on both sides. And they don't represent the majority, it's as if they were called "fringe" for a reason.

Anyways, you contradicted yourself twice, and one of those times was the very same thing you pretended you weren't arguing for. That's just dishonest argumentation, meaning this discussion is pointless, so I won't engage you further.

You could even go so far as to have a bank of batteries, be paid to take in power, then earn money selling it back to the grid later when prices are positive.

Well, if current physics is worth anything, a photon with a wavelength around that scale is probably going to spontaneously collapse into a mini-black hole. So that probably does count as a threshold of some sort.

It is a signal to ramp down or if you have a storage facility store.

If the prices remain negative or low for long periods it is a indicator to build transmission to where prices are high. Or if yours are a consumer build you factor or data center in the zone with low prices.
Among other things it would take 96 billion years to create the photon.

So that means whatever process created it needs to take that long. I'm not sure what would happen if the process is interrupted before it's complete. But I suspect the photon would "go back in time", and never have been emitted in the first place.

This "time travel" doesn't pose issues because the photon takes that long to be detected, so if it's interrupted it simply wouldn't be detected.

Perhaps not just when prices are negative, but it's not an uncommon practice to 'store' power by pumping water uphill when it's cheap and demand is low (generally at night), and then using that potential energy to generate and sell it when electricity is more expensive.

I have absolutely no clue what it would take to make that profitable, but it's a strategy for handling the natural spikes of demand when using power generation methods like solar and wind that are unable to adjust quickly to changing demand.

Wrong. That scenario is exactly the kind that quantum gravity is supposed to illuminate. Of course, we can't be 100% sure about that yet.
I'd recommend the book The Grid as a primer on how stuff like this can happen. Energy is strange, in the sense that everything produced needs to be used more or less immediately. Maintaining the energy grid is a careful balancing act between preventing surges and blackouts.

There are a lot of grid-related engineering problems that come from increasing decentralization (e.g. wind, solar, hydro) because it increases unpredictability in supply.

It would be idle most of the year though. Perhaps a big bank of resistors would be cheap enough to soak up some of that negative priced power and profit.
Oversupply is easy to burn up -- as long as there's robust and quick mechanisms for signalling when oversupply is going on.

There's plenty of loads that can be quickly spun up -- transferring workload from one datacentre to another is possible, as is running refrigeration systems to generate ice (or some other phase-change material) that can be used up during peak demand.

Anything remaining can be taken care of by bespoke energy storage systems, like batteries or pumped-storage.
Hmm you should probably stop talking to yourself...
A lot of hyrdro plants have exactly that ability. Buy low sell high.
While the utility of electricity for consumers may become zero, transport of it via the grid still costs money. So for producers the electricity price becomes negative.

WRT 3: There is energy recovery, but it's very small and it's more like impedance matching. They've been used for outright storage (eg DURUS) but the springs are usually just too stiff. It still saves energy since there's a smaller initial current spike, but it doesn't save energy step-to-step. Unless you take really small steps, I guess.
Power traders do this all the time. Each power plant/wind farm/solar farm has a generation cost and a time span that is required for startup or shut down. Balancing these factors and meeting demand the cheapest way possible is their business.

Also keep in mind that the price to consumers will never be negative. This would be only the generation and distribution side of the house.
I did Hack Reactor in 2014 and work at Google now as a software engineer (it's currently 2017).
Ideas like this unfortunately end up not being very economical because of the fixed costs of the infrastructure needed and the relatively low duty cycle of use.
Oversupply is only a temporary problem. When long distance transmission lines to other countries have been built, energy can be transferred across the continent to where demand or available storage is.
