The selection bias is those who want to sign up for the lottery vs. those who can afford to move into the area where their kids get zoned to the good schools.

The selection bias of SA pales in comparison both purely by principle and in practice by the diversity of it's students.
I believe the exit node may still be able to view traffic in plaintext. This is part of the reason that running an exit node is so "dangerous" in the US.

edit: Though with a quick Google, I'm led to believe that an exit node is only important when you are leaving the onion network (i.e. when entering into the Internet), and thus it sounds like SSL on a hidden service would indeed be superfluous to me.

However, SSL also proves authenticity, not just encryption. It would let you know that the hidden service you are accessing is indeed who you think it is.
> a lottery

This is exactly what I meany by quasi-selection. The dat are absolutely clear on this question -- lotteries create a very nearly insurmountable selection bias.

> public schools in NY are zoned so you have to live the right place to get your kid into the right school

This is immaterial to the question of whether charter schools are more effective than public schools for reasons that are essential to their organization (rather than incidental).

Furthermore, I don't think this (or any) anecdata gets to the heart of my criticisms, which I'll explain further below.

The core of the claim you made above -- that a charter is one of the best performing schools -- is not even a reasonable claim in most states because Charters aren't subject to the same testing and reporting requirements as public schools!

In many areas, Charters are not required to report at all, or are allowed to self-report. Guess what? Public schools also do totally fanstically when they are allowed to sefl-report! Comparing self-reported data to data obtained through a standardized process is meaningless.

Again, I'm not saying this is necessarily the case in NY. Just that it is a real problem nationally.
I think you're right. But I also think this is more important, symbolically. This gives .onion a status which prevents outbacksteakhouse.onion from being plausible, and ensures that "Any domain ending in .onion needs to be routed to Tor" is consistently true.
You're shitting me, right?

They're literally giving you all of the data in a plaintext format with documentation, and you're still complaining?

Sure, having everything handed to you on a silver platter is nice, but why should they do your project for you?
Thank you, I appreciate it.
Ditto. I suspect it is in part that they're looking at engineering entire and not just software engineering, because of both the prevalence of chemical engineering jobs in the Gulf area and job title restrictions on "software engineer" in TX.

This sets up IBM to compete directly with Monsanto's new Climate Corp in the ag-tech space. My hopes is that this drives the entry price of this tech down so it can actually benefit small farmers (who may have higher margins due to crop choice but lower profits due to size and economies of scale) and not just larger agribusiness operating on economies of size.

Pensions are known as "Defined Benefit" programs and 401(k)s are "Defined Contribution" programs.

The difference is pretty much what it sounds like. If you had a pension, you knew exactly how much money per year you'd make in retirement (the benefits were agreed to ahead of time). With a 401(k), you know how much exactly you're contributing and how much is in 'your' account, but the value of your retirement accounts in the future is dependent solely on how much you contribute and your personal investing prowess.

As companies and public entities underfunded pensions over the past 40 years, pensions started going bankrupt or dramatically cutting contractually obligated benefits that were to be paid to retirees, so companies began switching to employee-owned plans.

Shifting the burden of investing in retirement to the employees rather than the companies has its benefits but I think we're going to see a lot more elderly poverty as the boomers retire since on average, people are terrible at investing.

Not so much in this particular case — the purpose of the tunnel is to reduce heavy truck traffic through environmentally sensitive areas. The tunnel is explicitly built to satisfy a goal of transforming truck freight to rail freight. The fast passenger time is only listed as a side benefit.
That dynamic actually explains why all big-ticket retailers -- not just car dealers -- need to change business models to something like, "You pay for self-service showroom access to a variety of products, then make your actual purchase from [a level near] the OEM with minimal margin."

The only reason I tolerate(d) any interaction with car salesmen at all is the intangibles you get from a test drive. I would much rather just have some kind of option where I can try out car models at some place that doesn't have financial incentive to make me buy one of them.
Not a fan of screen overlay tooltips as in [1]. My first instinct as a user is to get them out of my way, and I do that every time, feeling guilty. And adding a "next" button and going through tooltips one-by-one doesn't make this any better, just more annoying.

Actual games (such as GTA or Cut the Rope) do a great job with onboarding, and apps tend to take the simpler show-everything-in-the-beginning way.

Two alternatives I've tried as an indie dev:

- Gamification, where you ask the user to perform one task, such as "drag X to Y." Only after they performed the action move on to the next prompt, and perhaps not even immediately.

- Utilizing badge counts or "bouncing" animations to indicate some action that needs to be performed. The benefit is that the user can try it on their own time, and you're not rushing them. The downside, though, is that some users may never actually click.

On the flip side, these approaches can add complexity in both code and how you structure your UI.

Think of how crazy things are right now. With Spotify or Apple Music you can just make lists of all the music you want and record the output. You could do this with terrestrial radio(I did!) but you couldn't control what was played so it was quite different. The only thing stopping people from having every song they ever wanted for $10 is laziness.

They aren't the same. "Pension" means defined-benefit pension. You work here for 25 years and you'll get x thousand a month in retirement. It's how retirement plans worked up until 1983 or so. 401(k) means market-based investing. You put y percentage of your paycheck aside, and the company may contribute some money, and it goes into Wall Street tax-deferred to hopefully gain value.
This looks interesting. Where can I find the docs?

The Linux Kernel does not have a public API/ABI apart from the userspace syscall interface.
Everyone complains about these things though.
Both Nvidia and AMD bypass legal issues because they don't distribute mixed GPL and proprietary code. Basically their proprietary kernel modules is being linked with Linux kernel by end-user and this totally fine for GPL as long as result is not distributed.
I'd say that's actually more common than employees being required to pay back all their compensation from their job.
I remembered those tricks but not the movie it came from. How true is this though ? even innocent people cracks down under pressure even if they rebel against injustice at first. The amount of "intelligence" and organization to protect whatever dogma a government wants to protects scared me. Noticed the check mark when the student asked for a little humanity.
I also take issue with your characterization of charter schools as all being run as for-profit corporations. The charter school environment and laws vary from state to state. California as one example has 1,198 charter schools. Only six of them are incorporated as LLCs, the rest are all either non-profit organizations or run by school districts. There certainly are for-profit charter schools, and in some states they have been an issue, but the majority of charter schools are run as non-profits.
> That does not imply he did his job properly.

That would not be surprising given that he was fired.

Unless you're suggesting that an employee who is fired should have to pay back all the compensation they were paid, I honestly don't see what you're trying to argue here.

The real problem here is that companies mistakenly place such an incredible amount of confidence in their CEOs and therefore offer them extraordinary leverage in the negotiations. They become convinced that they've found the one person in the world who can lead their company into the future, and once that belief has settled they're willing to pay almost anything to keep that person.
I think the idea that a new car is a fixed entity is a common misconception. Unless you built it yourself, do you really know anything more about this than a used car? In either case, it is a good idea to drive it, listen carefully to the car, and look for signs of damage (contaminated fluids, etc.)

The new one may have an advantage because of the warranty, but taking advantage of the warranty can be a huge hassle.

If you just want no-hassle car ownership, it may make more sense to buy an old beater that's running good, and when it starts to give you trouble, buy another one.
Calling it hate speech is very unusual.
What happens is that direct replications are actively avoided so that the possibility of a negative (as in bad) citation does not come up. That appears to be the most popular "solution" to this problem, to the point it has been institutionalized and journals discourage publication of replications, etc.

This effectively turns the area of research into pseudoscience in my mind. I don't see how a method that does not require independent replications can be considered science. I guess you could argue about the definition of science, but any method without replication is very different from the one that has brought great benefit to mankind.
No one is claiming their overall performance is better and I deliberately didn't talk about charter schools in general. I reacted to the characterization from exelius about how charter schools somehow was worse.

All I want is for my kid to learn first of all reading, writing and math.

I don't even care about whether one school outperform another but there seem to be various studies showing different things.

My guess is that charter schools work a little better because of the Hawthorne Effect.

https://en.wikipedia.org/wiki/Hawthorne_effect

And studies show different things. According to this it's better in general. But to me thats less important you can probably find studies that shows other things too.

Let's be honest, those 40W spikes are due to video playback and/or other GPU bound tasks. Sorry, wait for the battery on those. But booting the OS should be unconditionally permissible on AC power.

So design the OS bootstrap to never spike consumption past the load capacity of the power supply. Once booted, deny access to processes that will slam power consumption, until you have a sufficiently energized battery.

Hey, presto, a weightless solution solved in software without any additional added mass!

In spite of the headline, this article is not so much about doxing. It's about the fact that doxing is way too easy, because companies are ridiculously lax about keeping people's private information safe.

Schneier is arguing for government regulation, and letting people sue for damages after an information breach, and I think he's right. We have enough data at this point to show that very few companies are going to take good care in this area unless a regulator or their insurance company forces them to. It's too hard, it's too expensive, and it's too easy to brush off the consequences when the inevitable breach happens.
Can't speak for the original parent poster who brought it up, but it depends on the context.

The whitening of rock and roll, jazz, hip hop etc often meant watering down those forms in their original form, to fit more conventional, domesticated and commercial white audiences. That is, making the music more formulaic, the lyrics less explicit, the delivery less frenetic and/or urgent, the topics under discussion more tame, etc.

That is not merely some neutral stylistic change, but something like betraying their original "soul" and depth of the songs for cheap sales. In pure white terms, something analogous would be The Beatles -> The Monkeys, or Elvis -> Perry Como.

Almost certainly one of the various artificial object we discarded in orbit around the sun. For a complete list of candidate objects: https://en.wikipedia.org/wiki/List_of_artificial_objects_in_...

Because their orbits are so close to the Earth (essentially they're artificial near-Earth asteroids), they're periodically recaptured into quasi stable orbits around Earth. Example: https://upload.wikimedia.org/wikipedia/commons/3/39/J002e3f_...

>The object is only 1 to 2 metres in size, and its trajectory shows that it has a low density, and is perhaps hollow. That suggests an artificial object, “a lost piece of space history that’s come back to haunt us”, says Jonathan McDowell, an astrophysicist at the Harvard–Smithsonian Center for Astrophysics in Cambridge, Massachusetts. It could be a spent rocket stage or paneling shed by a recent Moon mission. It is also possible that the debris dates back decades, perhaps even to the Apollo era. An object seen orbiting Earth in 2002 was eventually identified as a discarded segment of the Saturn V rocket that launched the second mission to land men on the Moon.

Ahh yes, the curious case of J002E3, aka the S-IVB stage of Apollo 12. The example orbit animation above is J002E3, actually! https://en.wikipedia.org/wiki/J002E3

People rail against this, but I think it profoundly misunderstands the semantics. Gas is a resource. Money is a resource. Gold is a resource. A person is a resource. Nonetheless, only one of them is going to help my car go farther if I stick it in my fuel tank.

A resource isn't intrinsically a fungible commodity (when they are, we call them "commodities" ;-); often they are unique. The common trait of resources from a businesses perspective is that they are valuable to the business. Sure, I'd like to think I have more significance to this world as a person, but the day my employer doesn't see me as valuable is the day I start sending my resume around...

The other way to look at it is that while employees are individuals, they all take a paycheck. So, on the cost side, employees are all just different sized paychecks. When you are looking to assign employees to a task, you absolutely think about which individuals could/should be dong what, but before that, there is a decision about how much in the way of paychecks, if any, you ought to burning on that work. That first decision has little to do with the individuals involved.

While this is an interesting article, I have a minor quibble with the title - does the author really mean that her team is "predominantly male", which has a very different meaning than "male dominated"?

One just expresses a ratio of genders, whereas the other implies a distinct control and power dynamic.

Although that's mostly true (even though I'm certain there is a history of persecuted artists/writers/activists in the US), what does that have to do with the original article?

Nobody is contesting that United States was not a more free society than the Soviet Union. The implication of art as a tool for propaganda doesn't go away simply because there were other active artists who weren't funded by the CIA.
It's too bad ultrasonic transducers this size (~16mm) are too large to make a linear phased array with high angle range and low grating lobes [1]. This means that a different object or particle might be manipulated simultaneously with the target object.

I've been looking into using a genetic search or just brute force random search to create a randomized transducer pattern that minimizes grating lobes though. You can purchase these transducers in bulk for super low prices though! So anyway to build a capable phased array with them would be awesome.

Bryana refers several times to a fear she has been chosen or favoured due to her gender, and because of the positive discrimination we have allowed to happen in our industry.

Positive discrimination is not positive, because discrimination is never positive, no matter which group it favours. And here we see the consequences - a cohort of women who will suffer the paranoia of not knowing whether they were selected on merit. And a cohort of men who will have their misogynistic prejudices reinforced because the bar was visibly lowered for women.

This tunnel as well as its predecessor is mainly for rail travel. Trains are already far safer than cars (and there is no reason to believe self-driving cars will be safer than trains), and already let you work en route. Also, this tunnel is for freight rail too, and self-driving cars or trucks aren't really an alternative to that either.

Also: productivity in the office > productivity in a train >> productivity as the passenger in a car. I say that as someone who commutes about three hours a day by train and Uber.
