Apologies, what I wrote wasn't very clear. I didn't mean to imply that an API should only be able to handle such values, just that a linear color space is the only sane default in my opinion. And I most certainly didn't mean to imply that color channels should be limited to only 8 bits, just that it's a very common default (and often sufficient for simple tasks). As you very rightly point out, any even semi-modern API absolutely must be able to support the use of other color spaces when requested.

> Most APIs that do [0, 255] are assuming sRGB

I admit that I've almost exclusively used OpenGL so my impression is far from expert, but I don't think this is correct. My (admittedly limited) experience is that a linear color space is assumed unless otherwise specified. In particular, my understanding is that OpenGL works almost exclusively in a linear color space except for a few specific sRGB image formats and a few specific functions. For arbitrary non-linear color spaces I would generally expect to need to select a backing format of the necessary bit depth, output linear values, manually apply a conversion function, and then somehow indicate to the underlying hardware what color space to use when displaying my image data to the user.

> OpenGL actually works like I said - the float values are not limited to [0.0, 1.0].

Agreed, I never meant to imply otherwise. However, do note that when outputting values from a fragment shader their range (and type) has to match what the GPU is expecting. So in practice, unless you're using a floating point image format (such as GL_RGBA32F) your output range is going to be limited. Personally I almost always use unsigned normalized formats.

> This all matters because there is no longer any platform on which sRGB can be safely assumed to be the overwhelming majority.

I'd just like to point out that in principle, a hypothetical API could handle all programmer interactions in a single color space (eg linear) and then transparently convert as appropriate for the display device currently in use. Of course it goes without saying that all conversions must be handled correctly! Importantly, I'm not trying to claim that such a limited design would be a good one. Rather, my point is simply that conversions between color spaces are purely an implementation detail provided you have sufficient bit depth to work with.
You appear to be conflating a credit with a deduction.

A deduction reduces the amount of income thats taxed. So for example if you're in a 25% marginal tax bracket, deductions are worth 25 cents on the dollar.

A credit reduces the amount of tax you owe, dollar for dollar. In addition, some credits are refundable, meaning that they're allowed to make your tax liability negative for the year, so you get benefit from them even if the credit is more than the taxes you would otherwise owe.

And to be clear, when I talk about the "tax you owe", I mean the total amount of money you need to have paid the IRS by April 15th, including payroll withholding, estimated tax payments, and so on, and not the size of check you need to mail to the IRS in early April.
Self-Driving Car Startup Drive.ai Seeks Potential Buyers
In my obviously very biased opinion as a TM3 owner, I am both happy and sad for this news.

The Tesla store in the mall near my house is fun. My kids love going there and sitting in the different models, and my son knows how to trigger all the Easter eggs, like making the X falcon doors dance.

At the same time, I have zero use for the store now that I’m an owner, and I had zero use for the store in actually making my purchase. The test drive that I did finally do of the TM3 (after I had already put $3,500 down and was entirely certain I would be buying the car) was actually underwhelming because I didn’t get nearly enough time with the car to really appreciate it, nor get to drive it in any kind of interesting terrain.

Actually driving my own TM3 on the other hand blew me away from nearly the first moment and still does.

I wonder how many owners are like me in that with the massive quantity of YouTube videos and reviews, already knew with certainty a TM3 would be their next car without actually needing to drive it? BTW, I’ve never had that with another car, and never would have dreamed of buying a car without driving it, before Tesla.

At the TM3 base-range $35k starting price, I think the vast, vast majority of people who “trial” one will keep it. This is particularly true if you’ve already made any kind of actual arrangement to charge it at a decent kW rate.

I would add that they need to have a trial mode of the full auto-pilot functionality, and also perhaps the ability to pay monthly for auto-pilot software subscription rather than bumping up the sticker price. This would also help with reducing sales tax and excise taxes I think.

I just hope the car-buying public is ready for this. Tesla will rely heavily, extremely heavily on word of mouth without a way for people to easily get in and touch and test drive a model with no commitment. Luckily I give test drives to everyone I know who I can talk into it, and I’m guessing most owners act the same in an effort to evangelize.

But as they try to go more mass market and compete with the Accords and Camrys, as they have less of the evangelical early adopters, will that target market a) have the charging infrastructure readily available, and b) really be willing to buy purely online and sight unseen?

I want this to work, and fear that it won’t. They are pushing so damn hard to get to that $35k price point with any kind of margin left over. If they had another year of process improvements maybe they could do it even with the stores. Without a store they can pull forward a profitable $35k TM3 several months at least. So it makes perfect sense while still being a huge gamble. Wild ride.

I don't see why it's amusing though - it made sense as a way to keep costs down then and it does now. What's the problem?
While service is an issue, the bigger issue right now is repairs after an accident or other, bigger problems that can't be fixed in a "daily visit on site".There are people waiting three to six months for repairs: https://forums.tesla.com/forum/forums/why-does-it-take-month...

My boss had to wait more than three months this past fall after his accident, and he was making payments the entire time (of course) --- they have not fixed this problem. And no, most insurance will not cover a loaner for this period of time.
There is a lot of money going from universities to publishers, be them traditional or Gold OA. Researchers would rather use either Green OA (like arXiv) or Sci-Hub or articles available on other researchers pages.

Is therefore interesting that a big university makes this move, with the argument:
"the publisher would have charged UC authors large publishing fees on top of the university’s multi-million dollar subscription"
“Courageous”

If anyone has ever had to cancel a car sale you’ll realize how much of a hassle it truely is to “return a car”

Your credit report will show a loan even after it’s been cancelled for weeks.

I once cancelled financing for a car due to it not being as described. Started looking for a new car and found it.

Got denied for a loan because my score showed a 60k loan with 0 payments made. It took almost 2 months to fully remove it from my report and start with a clean state

In summary, Tesla is essentially saying “you can’t test drive it but if you don’t like it you can cancel your car search for a few months and ding your credit score for nothing”

This is like mattress stores that give you a “free trial”, they know the resistance to actually doing ending your “trial” is crazy high
I liked it for the perspective of someone who grew up here, went to Silicon Valley elementary and high schools, saw the toll the culture took on her peers.

Maybe more for me than you- I'm raising 2 daughters here.

The starting point of Perelman's proof is the observation that (a modified version of) the Ricci flow is a gradient flow. The connection to 2d non-linear sigma models is briefly discussed in section 2 of the introduction in https://arxiv.org/pdf/math/0211159.pdf and section 1.4*. The overall intuition is that string theory captures the geometry of the back ground Riemannian manifold.

I do this very often. Usually, I'm looking at a very large project (think glibc, WebKit, etc.) trying to find a certain thing (where is this output coming from, what code path leads to this behavior?); so I really only need to look at a couple of files. It's really not worth cloning the entire project for one little thing.
Especially when it is so good that it looks like a black box to the word: correct input -> correct output; and nothing more.
Certain tax credits apply even if you don't have enough liability. Like if you owe zero taxes for the year for some reason they will send you a check for the full credit amount. Not sure which category the EV one falls under though.

Well you know my last job I worked on a system that was a lot of 4gl under the hood and a Java application that sat on top calling the legacy 4gl code. The 4gl code had comments in the header with dates and ticket numbers. The dates stated late 80s and 90s. The ticket system was from 4 ticket systems ago so that was useless. The comments had become wrong over a period of 30 years of changes. The rationale for something in 1989 made a lot less sense for 2015. The author was now the boss for the whole office and hadn't touched code in 25 years so I can't go ask him about this function he wrote in 1989.

Entropy. It's not our friend. It's why we can't have nice things. Code bases suffer from bit-rot over time.

You've managed to circumvent my entire post and you're still wrong; my point was that ideas are communicated through a medium, and they can even be communicated through, for instance, threats and pornography. You have given no convincing reason to single out child-pornographic images for censorship while allowing others, such as regular pornography. What differentiates the free speech content of child pornography from other pornography, or even art which required harm in its creation?

Obviously I'm not defending child pornography here, but I think there's a logical flaw in your reasoning.

The fact that ideas can be communicated through other media is irrelevant, since it would mean that we can censor whatever ideas we like in any major category (e.g ideas conveyed in photography and film) but thereby only farcically allow them otherwise (e.g the expression of the idea is only allowed through physical speech).
I'm well aware, and it doesn't change my opinion.

You're probably right. The point is, SS is taxed separately for a reason: it goes into a trust fund, to be used only by the SSA. However, even if you never changed that (meaning you remove the cap but still keep all payments in the trust fund) they would have to fundamentally change how benefits are paid out.

The SS trust fund is used for SS retirement. SSI, while administered by the SSA, comes from the general fund.

Neither of these models predicts superpartners. The AdS theory doesn't include the standard model. The N=4 theory doesn't even have particles. They're toy models, albeit rather sophisticated ones. Their utility is that they can give us concrete demonstrations of various conjectures about gravity, holography, and gauge theories.
Heat pumps all have defrost cycles where it'll run like a regular air conditioner to heat up the outdoor coils temporarily to melt off ice build up. It turns on auxiliary electric heating inside in order to maintain heating while it does this. Yours clearly is broken in some form or another, it's either not going into a defrost cycle at all or even a full defrost cycle isn't enough to melt all of the ice and it's building up faster than it can be defrosted. Just call an HVAC company and get it fixed.

Try buying a BMW with the $328/mo lease that they advertise every day. Tesla is waaaay less shady than any car maker. Their base model comes in with a LOT of features that other car makers will nickel and dime you to death. Example, LED lights.
Over the timespan in which you'd have to replace it, and given future cost reductions in battery production, it's probably the same as the total cost of maintenance for a petrol car. The cost of getting a petrol car to 100k or the 10 year mark isn't cheap. Even a Toyota is going to run you like $5k. A BMW or Benz, probably closer to $15k. If you buy a used BMW 3 series for $20k today and keep it for 10 years the cost of maintenance + gas will be well over $20k. A lot of people greatly underestimate the total cost of ownership for a petrol vehicle. Best case scenario is you have to replace every moving part that isn't the engine itself. Worst case scenario is you have the replace the engine too.
I find the abstraction of men vs. women to not be the optimal one.

Well... the other reason might be that the German Universities got together to negotiate with the big publishers. While agreements are in reach or have been reached with most of them, Elsevier continued to try to throw it's weight around leading to most German academic institutions letting the subscription to Elsevier journals lapse (or cancelled) at the end of 2017, with the remaining important ones following suite at the end of 2018.

Currently almost no academic institution in Germany is subscribed to Elsevier. Here is the full list of German Universities and Labs currently not subscribed to Elsevier:

https://www.projekt-deal.de/vertragskundigungen-elsevier-201...

Elsevier did not actually shut down access to its journals for German institutions.

Wiley on the other hand has just signed a contract with DEAL, and negotiations with Springer Nature are going well enough so interim contracts are in place until they are concluded.

When the Interests of Monopolists and Authoritarians Coalesce
Actually, you'll probably never need to change the battery as "the latest data shows less than 10% degradation of the energy capacity after over 160,000 miles on Tesla’s battery packs" [0]. Even if it degrades like 50% by the time the rest of the car dies, there will probably start to emerge a market for the old batteries to use them for grid storage where kwh/weight does not matter as much so you might even get some of your money back.

Dealing with dealers is such a PITA though, they are mostly full of hidden tricks, and you really really have to be savvy to not get ripped off on something. I wish I could just buy the car I wanted without worry about any of that.

I guess I'm interested in 3D stuff because I feel like I'm living in the birth of a new medium, like when people discovered painting, or dance. Most people doing 3d are doing stuff you could do in another medium, like film but cheaper, or interactive.

On the one hand, you're absolutely right when you say that it's largely unproductive to work outside of your speciality. On the other, I think it's a bit like painters learning to make their own frames and mix their own paints. It's not strictly necessary, but it deepens the understanding, and it opens the door to loads of stylistic discoveries.

I think the thing I like about python, or programming in general as a creative technique, is the combination of amazing fine-grain control, with absurd expressiveness. The kind of techniques you learn as an artist are usually strong on one or the other. Crosshatch gives you a lot of control over light and shade, but it's a time-consuming, boilerplate kinda technique. Most traditional techniques are like that, or, like throwing paint at a wall - very expressive, but no control.

Programming the creation of sculptures and images is the kind of amazing opportunity that it feels sort of crazy to pass up. I've spent an inordinate amount of time refining my ability to draw nice gradients with a set of pencils - and now I have a machine that can give me a perfect gradient with a couple of lines of code!
The ACM is similar, and I think (hope) they will eventually have to just open up all published papers by default. The main difference between the IEEE and the ACM to Elsevier is that the IEEE and ACM are professional organizations. They have a non-profit mission, whereas Elsevier is a for-profit company. I have no problem reviewing papers and serving on program committees when the organizing entity is a non-profit service organization. I think the the ACM and IEEE have a future in a fully open-access world, but Elsevier does not.
This is very good advice to keep in mind, but it's not Tesla's fault if the credit reporting agencies are terrible.
It actually understates the savings, since it only captures the Federal credit. CA gives out $2500 extra AND carpool stickers (admittedly more valuable than the tax credit)
Over on today's $35k Tesla Model 3 announcement thread, there's a whole bunch of "Dark Pattern!!!" pitchforks being jostled about because Tesla threw fuel savings into their "effective cost" price tag (the MSRP is still $35k, but the subsidies and fuel savings bring the "effective cost" down to the mid/upper-20's).

We as consumers seem to ignore or discount future pain for lower prices now, which is why operating costs are ignored by average consumer if they mean higher upfront costs. And when marketers try to bring future savings into the present and get you thinking in terms of total cost of ownership, even the rational-types at HN cry "dark pattern!"

All of this is to say we haven't yet found how to make "it's cheaper to live in" an effective message.

Solar folks are getting there, though ("the system pays for itself in 5-7 years"), and with the rise of EV's, I think this reasoning will become more common.
Survivor bias. The fortran that is still running is the elegant stuff, the stuff that was written well enough that nobody has needed to touch it for decades.
