I'm pretty sure that's not literally true. For example, take a CRT, with its built in power law voltage-to-intensity response (the original gamma correction). If the eye didn't compress red, you'd see large shifts in the color of a white color ramp.

The last time they had a global problem, everyone scrambled for more than a week. (Cloudbleed)

This 30-minute global outage was pretty nasty, but not anywhere near as awful. Timing helped, as nothing truly critical was affected. (There are some extremely high-volume sporting events which, if affected even just for few minutes, can have a direct impact on the bottom line.)

I do not wish to see more of these. Cloudbleed gave me two weeks of headache and an indigestion problem. This one did basically nothing. If there is a happy middle ground between the two, I am not exactly thrilled at finding out what it is.

It is absolutely the job of the server to determine the source and validity of a request. Web browsers, for better or for worse, fundamentally allow websites to make requests to other sites. "Rogue" websites can "trick" users into requesting images, videos, music, javascript, stylesheets or trick users into making POST requests to your site. This is why tech like csrf tokens exist.
Agreed, I'm not saying that everyone needs to be using Windows Server for every build task, I'm just saying that it's silly to complain about Windows client being engineered for clients by default. If you're knowingly going to take that cost-cutting measure then you ought to accept that the default config will have to be tuned for your use case.

Farmlands are already solar arrays. They are just making power rather than produce now.
Neither the “engine”/“power generator” distinction you are attempting to make, not the statement “gas burns at a higher energy than steam”, is physically meaningful. It is true that supercritical steam turbines operate at a lower temperature than gas turbines, and if the cold reservoir of the Carnot engines in question were at the same temperature, that would indeed make gas turbines potentially more efficient. But in fact gas turbine outlet temperatures are much higher. This is why adding a steam engine to the output of a gas turbine makes it more efficient. (This is called a “combined cycle power plant”.)

The actually relevant distinction is that gas turbines, like other internal combustion engines, have a much higher ramp rate than external-combustion engines like a steam turbine. This makes “peaker” gas turbines a crucial resource for establishing power grid stability.

Well, this isn't so much a question of whether there was progress at all, because, as you're saying, the industry was booming all over Europe, but a question of what parts of the Russian Empire would benefit from it the most. One would think that a Russian Emperor would do everything to make sure that it's the metropolis that gets the cake, not the peripheries. All the more that Russia had been lagging in the industrial development, as would later be brutally demonstrated during the Revolution of 1917, so focusing on the western provinces would seem like a misinvestment (clearly, in the case of a war they would be the first ones to be chopped off). Of course, I'm not saying Alexander II was a covert lover of all things Polish. In fact, at times he, just like Alexander I during the Kingdom of Poland era (1815–1831), would have to back down under the pressure of the Saint Petersburg elites, who were not happy with a favourable policy towards Poland. Intuitively, one would think that a Russian emperor would put the interests of the metropolis first, and use, or even exhaust, the peripheries for the good of it. It's what the British Empire would do, for sure. ;-) Yet, under Alexanders I & II it was different. Which is why I think he deserves a radically more nuanced description than an occupier.

Dijkstra's write-up is full of subjective aesthetic judgements that certain things are ugly. I personally don't find `1:0` for an empty sequence to be ugly, and I do find using `1:1` to refer to an empty sequence and `1:2` to refer to the sequence `{1}` to be ugly. I would encourage everyone to read over his reasoning and see if you agree with his aesthetic judgements.

Might be late, but has anyone in CloudFlare tried to switch away from regex to something more efficient and powerful?
Tools like re2c can convert 100s of regexs and CFG into a single optimized state machine (which includes no back tracking, as far as I remember). It should easily handle 10s of millions transactions per second per core if the complete state machine fits into the CPU level 3 cache (or lower), with a bit of optimization.

It's such a drag how far Strava has fallen. 7 years ago I thought they were a stellar example of how tech can be helpful and innovative in simple but meaningful ways. Now nothing of interest has happened in several years and what has been added almost takes away from what was good in some ways.

I think Strava was a passion project for some people working there a decade ago, but I suspect they're long gone and the people there now have much different objectives and leadership.

I think I'll delete my account. Does anyone know of an up and coming alternative? This space seems to be loaded with great apps that kinda lost steam and fell into decline.
Yes, it's highly likely the continued rise of utility-scale solar and lower retail electricity prices will impact the financial sensibility of home solar. Of couse, California recently mandated solar power on much of new home construction, so the state forced the issue and we're likely to see more legislative and legal efforts from its opponents to fight it, and from its supporters to try to remedy those impacts that defeat its point. Net metering is a widely-deployed incentive to encourage home solar, but is opposed by plenty of influential lobbies. Homes with solar have some unique benefits, like added resilience from grid fluctuations, but it remains to be seen what monetary value people will place on such features.

As with many things, the story of home solar will likely be one of early adopters duped by bad numbers and opportunistic businesses, of jurisdictions mandating the issue and running into all sorts of unintended consequences, and a tangled web of policies enacted to fudge the numbers until the observed costs to the affected people pencil out to a socially-acceptable level of hardship or benefit.
The definition of "hate" is a loose and subjective. Facebook's own internal studies show that hateful or "aggressively polarizing" posts garner the most user interaction, and that user interaction informs the psychographic profile of the users interacting -- which is data that Facebook sells to advertisers (and allegedly nation state actors).

I like the idea of just letting people say what they want and only taking action when people engage in criminal speech (inciting violence or other illegal activity) and making liberal use of mute and block features in online platforms.
> I really wish I could find out the answer to how this works

It's billing code optimization. Doctors aren't specialists in billing/diagnosis codes, and their time is really valuable, so many of them tend to use a handful of fairly generic defaults they're most used to and then move onto the next patient. This is what you paid when you left.

There are really, really specific requirements for many billing/diagnostic codes, which will each have a fee defined against them. If a code requires a specific question to have been asked or a specific set of actions to have been performed by the doctor, if even the most minor component is missing it risks having the claim rejected[1]. Or more specifically, if it's missing _from the doctor's notes_[2], such that there's no documentation that it was done/asked, then it risks being rejected.

An asynchronous process got kicked off after your visit, where your visit details went into the queue for either a medical coder (either human or software) to review visit details, prognosis, and doctor notes. Then, based on their findings, they adjusted the code your doctor originally used (either changing it entirely, or adding supplemental codes). That's why you got an incremental bill at the end.

[1] This is in the case of insurance companies. If a medical practice wants to charge for a code, the insurance company demands the requisite documentation to justify the use of that code. I've never tried it, but you may have some success disputing the bill by _also_ requesting the specific diagnostic codes that led to the incremental bill, as well as the supporting documentation to justify the coding. Which is what an insurance company would do, too.

[2] This is one of the big benefits of an EHR to a practice. The EHR workflows can be set up to require a bunch of boilerplate information be collected and processes be followed, which generates very rich visit notes and provides a lot of opportunity (and documentation to justify) for upcoding a visit. Which usually makes administrators/practice managers happy, while mildly annoying physicians.

Cool story, thanks for sharing that.
Agreed that people should be held accountable but there is not a great process for this. Usually the fallout from bad policies for backups / continuity are down to a roll of the dice. Too many of the people in charge are willing to roll the dice, and too many will understaff IT and then not listen.
The policies that using Studies in this way violated are listed in my initial post. Those policies were created to prevent Studies from being used as a convenience.

You might think violating them was justified, but that they were in fact violated is inarguable.
That's not how these contracts actually work. Certainly Amazon COULD act against their customer's interests but the customer will be around for a long time, so that would be really short-sighted.

The process for re-bidding them starts a long time before the contract ends, and often the incumbent will offer a temporary contract to cover the time between the end of the contract and the beginning of the next contract. The process is unpredictably long because one of the losers -- especially if it is the incumbent -- may protest the award.

A similar thing happened with a contract I worked a lot with and the new contract (much smaller than JEDI, but still ~$2BN). The contract was to replace legacy datacenters with cloud services and service management layered on top, and was an IDIQ (Indefinite Delivery, Indefinite Quantity) contract -- it was held up in protest so long after award that the government just ordered nothing, and came up with alternate strategies. The protesting entity was one of the winners of the bid (unlike JEDI, it was awarded to 4 parties, though they were all reselling AWS, Azure, Google, etc) and they ended up with nothing from this very expensive and time-consuming bidding process.

We're starting to see things shift away from simple panel installs on a home being as quite a good deal as they were. They still make economic sense, but the caveats are coming. When we got our system in 2015 (Bay Area, California), the full tax credit and rebate system was in effect, which wound up shaving more than a third of the cost off of the total system price. Then, we were able to get on a rate plan (PG&E E7) that paid us quite well for our overproduction.

A year later (2016), PG&E 'retired' the E7 plan, as it was too beneficial for home solar users. We're now on the E6, which is not as good, but still better than the straight TOU plans PG&E currently offers. Next year, even the grandfathered E6 plans are going to go away, and solar customers will be on a time-of-use plan that extends peak hours until well past dark, making it again more difficult to recover solar's cost as a homeowner.

This will be able to be offset to some degree by systems like Tesla's PowerWall (I don't have one yet, will consider it in the coming years) but it's definitely a game where the utilities have a love/hate relationship with people who own their own systems.
Regulation like this works when there are increasing consequences.

Sure, yes, but the comparison in question isn't the only comparison, it's just one of many. Letting people see the difference visually for themselves is more tangible and less questionable that putting up two file size numbers and claiming they're equal quality. And if you think about it, it similarly wouldn't completely be fair to BPG to turn up the quality so that the JPEG looked reasonably good, because the BPG file would be in the range of diminishing returns per byte.

It is fair to point out that JPEG falls apart below a certain compression threshold while BPG doesn't, even if it's a little bit apples to oranges. I prefer the way @enriquito said it https://news.ycombinator.com/item?id=20419900 but I disagree with the hyperbolic claims in this thread that this comparison is outrageous or complete spin or cheating. It's a data point that has some actual merit, and BTW happens to agree with the other data points we have.

Perhaps a better statement would be that the duck curve represents unmet need in the evening once solar is in the mix. Without storage, you can add more solar, but into the evening that can only help so much without also adding some amount of storage to offset that available power into a time it is still needed.
Real ID gets us much closer to having a national ID. Give it time.
You're right...I've got an availability bias that has limited my thinking. Any application where energy density is paramount will be dominated by fossil fuels for quite a while.

I'm curious to see what comes first: batteries that match the energy density of fossil fuels, or cost effective synthetic fuels created via renewable methods.
Well the WINE folks have their heart in the right place, but its not really a good idea to re-implement a proprietary API for the purposes of binary compatibility. In any case, it makes sense for Windows Version N+1 to ensure compatibility with buggy applications that worked in Windows Version N. From an end-user standpoint I would hope all operating systems invest resources in ensuring application compatibility.
Then why is it RC and not release?

Interesting question.

I can't say for sure, but my take is it probably wouldn't, based on a couple things:

1. I've known people who work sales for companies located across the country. We don't consider these jobs "remote" like the tech world, but they're similar in most respects. They own a home in a different city than their employer.

2. Banks and brokers are, for the most part, dying to give away money. The employment section of the mortgage application often doesn't ask much more than how long you've worked at your employer and what your salary is (sometimes a letter from your employer is required, but should be no problem).

Just apply, it doesn't hurt.
The excerpt, applies to copyrighted content created by you and submitted to their platform. So the question is whether credit card transactions are creative works or facts.

If credit card transactions are a creative work then you are eligible for copyright protection and this part of the terms of use would apply. However, if credit card transactions are facts (in other words if it is a fact that $x was charged to this card on some date) then they are not eligible for copyright protection and this section of the terms would not apply.

There is no way to know whether credit card transactions are creative works or facts until someone tries to claim copyright over one in court, however, to my knowledge that has not happened yet.
> theoretically any existing dam could be converted? Just need to pump some water back upstream when there's excess load in the system.

For that, you need water that can be pumped back upstream, that is, you need also a lower reservoir. If your dam discharges directly into a river, you won't have enough water downstream of the dam to pump back upstream. Not all dams have suitable geology to form another reservoir below them. An alternative would be to create a new reservoir higher than the dam, using the existing dam as the lower reservoir, with a set of tunnels with the reversible generator/pumps linking both reservoirs (this new upper reservoir does not need to be in the path of the river).

>Plus there are many reasons to install solar, not just financial.

The thing that surprised us the most when we installed our home solar system was how much cooler the house was during the summer, just because of how much the air-gapped panels on the roof reduced the heating load on the house. We noticed a significant reduction in our AC bills during the couple of months we had the system installed, but couldn't use the power due to permit-waiting.
I've found Plots.jl and PyPlots.jl to work well for most basic things, despite not always being entirely pleasant to use, for example the compilation time issue, but this should hopefully improve. The only real problem I had is that these are not quite sufficient for plots to be published in a paper, many visual tweaks you might want are broken or terribly documented, and I have to just use matplotlib or R. It is generally great for jupyter notebooks though. I see the current deficiencies as highlighting just how much work went into matplotlib and others to get where they are today (and even mpl is in some ways still lacking, for example 3D surfaces and meshes). It is unfortunate though, as plotting is a core functionality for their main target of computational science. But to answer your question, mostly yes. Everything seems to be slowly improving though.
Facebook previously stated that they were expecting a fine of ~$5B. The fine + uncertainty was already priced into the stock.

The market is reacting to the removal of that uncertainty, which is the same as a reduction in risk holding the stock.
Free updates. Not brand new free products. "Free updates" does not mean "if Dropbox removes a feature we'll do a ton of work to replicate that feature and give it to you for free".
I think pre-cooling would be a viable solution to cooling houses in the after afternoon, early evening. There are some issues though. Pre-cooling means cooling the house to a lower temperature during the early afternoon when the heat pump is working against higher outside temps. There is some loss of efficiency from that. Eyeballing COP curves makes it seem like you'd need 20-25% more power.

What I think. Demand metering in a solar grid would likely motivate people enough to cut late afternoon and early evening usage. So I think policy and rate setting can match infrastructure and it's costs to demand.
