I am not a fan of GLAAD definition. I think it does more harm than good. Gender Dysphoria, the condition associated with transgender individuals, is most likely neurological in nature - that is to say, there are plenty of studies correlating sex-atypical differences in the brain with gender dysphoria. (http://transcience-project.org/brain_sex.html)

Lumping in cross-dressers and run-of-the-mill gender variance denies this very real condition the attention it deserves, it reduces it to a choice. There is nothing wrong with the choice, and people should have the right to express their gender however they choose, I just think that we need to be careful about maintaining a separation between gender dysphoria and gender variance.

On the actual question at hand, clinical intake studies have been pretty consistent in this regard. The number of people who have gender dysphoria that becomes severe enough to prompt treatment (in western European countries) is about 1:10000 (for transgender women) and 1:27000 (for transgender men). (Judge, Ciaran, Claire O'Donovan, and Donal O'Shea. "Gender dysphoria-prevalence and co-morbidities in an Irish adult population." Neuroendocrine Science 5 (2014): 87)

That being said it is difficult to estimate the number of individuals with gender dysphoria who choose not to seek treatment (or those who choose to self medicate). People like John are unfortunate, and a hopefully the bi-product of an age we are on our way out of. That being said, John is clearly not transgender, they may suffer from gender dysphoria, but they are not transgender.

Today we have a much better understanding of gender dysphoria and have a number of long term studies which show hormonal and surgical transitioning to be an effective treatment (e.g Gorin-Lazard, A., Baumstarck, K., Boyer, L., Maquigneau, A., Gebleux, S., Penochet, J.-C., Pringuey, D., Albarel, F., Morange, I., Loundou, A., Berbis, J., Auquier, P., Lançon, C. and Bonierbale, M. (2012), Is Hormonal Therapy Associated with Better Quality of Life in Transsexuals? A Cross-Sectional Study. Journal of Sexual Medicine, 9: 531–541. doi: 10.1111/j.1743-6109.2011.02564.x). I

“First you ask about what sex is on your birth certificate. Then later in the survey you ask, ‘What is your gender?’? - This, of course, doesn't work in first-world countries where gender dysphoria is treated like an intersex condition and the individuals are free to amend their birth certificates.
I think the problem with going fully "designed" is that the design will be very fragile, because of how poorly we can model complex systems. The wonderful thing about the ecosystem is how resilient it is to problems... species diversity and genetic diversity within a species counteracts most potential problems. No matter how much suffering is caused by the natural state of things, it's better than having a designed ecosystem with minimal suffering that breaks when some pollutant or natural event kills a link in the carefully designed chain.
http://en.wikipedia.org/wiki/Captive_portal lists three ways to achieve it. The details will depend on how Starbucks decided to do it.

What you're asking is, in essence, "how does ethernet work?" That cannot be explained in a few paragraphs. You can start with Richard Stevens' "TCP/IP Illustrated, Vol. 1", as one of many available descriptions. You can use Wireshark to track all of the details.

At this point you should stop asking questions here. There's likely no simple answer, and this is a great chance to experiment and figure it out for yourself.

(Even if someone knows the exact details of how Starbucks does it, you are unlikely to understand the explanation without understanding some of the fundamentals.)

I tried to make this case back in August after the Spaceship One accident.

"Someone dying is devastating. Trying to conquer space a handful of people at a time is the slow and dangerous way of accomplishing this task. We should be building machines to explore the solar system. This can be done for a fraction of the cost, time, and it will allow him to allow us to iterate quickly.

In 100 years, more humans will live off earth if we iterate with machines, etc now than if we move slowly trying to reduce the risk in order to keep humans safe."

I am a programming newbie. We just started learning CS topics through Python. Everything was fine up until we hit "Objects and Graphics". That has to be the most inefficient and inelegant way of doing anything at all. At this point I am not even sure if I ever want to touch graphics in Python. What are some languages where dealing with graphics and objects is closer to working with purely mathematical objects rather than doing insanely tedious engineering style plug-n-chug work? Sorry, if it offends some. Didn't mean that. Thanks.
I see this attitude a lot, and I suppose that there is a certain truth to it, but it always seems incredibly short sighted to me. I am never sure how to respond except:

-humans are incredibly unsuited to cross large stretches of ocean.
-humans aren't built to travel faster than a horse's pace.

There is no new information here. It looks like sciencealert.com got its information from businessinsider.com's Dec 11, 2014 article which references a "new video" as its source:

https://www.youtube.com/watch?v=yLD1TPsEi3E

but that "new" video is from 2012.
The article title refers to a "plane engine" not a "plane." There is a huge difference: the passenger plane airframes everyone knows and flies on are made by totally separate companies (Airbus, Boeing) from the engines (Rolls Royce, GE, Pratt & Whitney).

A great engine will get you nowhere without a great airframe, and when you start talking about supersonic passenger service, you have to add politicians as well. For example, the Concorde briefly flew between London and Singapore but was stopped partly due to complaints from the Malaysian government. And of course the Concorde is long since retired, despite no comparable replacement existing; this has nothing to do with its engines not being good enough.

> there are plenty of studies correlating sex-typical differences in the brain with gender dysphoria.

There are also plenty of studies showing the opposite, as well as studies showing trans people being, on average, somewhere in between the male and female averages (on the specific area of the brain observed - generally different in each study!). The fact is, we just don't know.

And that's why GLAAD's definition is good. Trans people deserve respect and fair treatment regardless of what causes some people to be trans and others not to be trans. If we find out tomorrow that brain differences can't explain being trans, that doesn't change how trans people should be treated.

And it will probably be quite some time before we have a good answer there. We still don't know why some people are gay and some aren't, for example, and that has received far more research interest. The answer to that question, and to the trans question, will likely be quite complex, scientifically. But ethically, the answer is simple - just treat people nicely regardless.
You make a strong logical argument, but it relies critically on the tests being really great. Have you examined the sample questions as well as the standards? And even if the tests are great (they are not) do you have any idea how well this will play out in real classrooms? I ask because, as a veteran teacher, my guess is that CCSS will be great for the top two deciles and a disaster for the rest. The super worst thing is that no one knows because this top-to-bottom overhaul has not been tested/proven anywhere. That is just malpractice, on an enormous scale.

Exactly. For Google's long term credibility and success, they must close Google News Spain (at least temporarily).

A MAC address is part of their network once you attempt to connect to their wifi. The MAC address identifies your physical network adapter to the router. Once your network adapter is known by the router, the router can assign your adapter an Internet Protocol (IP) address.

It's really not quite fair to describe videocore as a GPU, it's a proprietary SIMD DSP architecture with a really awesome 2D register file.

There is no foundation for this argument to stand on.

Besides the fact that sending humans vs sending robots isn't a zero sum game, we're also sending robots out with decreasing frequency as well. "We should be happy to just send robots" would be great if we were actually sending robots. Here's hoping China and India pick up the mantle when Oppy and Curiosity finally shut down, I guess.

The reality is also that we don't learn much science with practical benefits for the hundreds of millions to billions of dollars we spend on these probes. Of course, we also get wildly poor returns on investment for the hundreds of billions to trillions of dollars we spend (in the US) on defense and health care. What we've decided is that it's worth it to spend a small amount of our money on the exploration of our universe, that discovery can be its own reward (and if there's a small chance in practical payoffs down the line, even better). We don't need to see what the surface of Pluto looks like, but I'm pretty excited to find out about it. Dismiss that as PR, but apply it equally.

This argument functions similarly to the one demanding we solve all the problems on earth before we start spending money on space. It assumes a way of allocating funds that doesn't match reality and demands unrealistic requirements not imposed on the favored approach.
This looks fantastic. Python always feels like it's almost as good as a dynamic, imperative language could get, but I miss some of the functional idioms from other languages. It's great that this is just a thin layer over Python too, so it can hook into the ecosystem, and it's a realistically sized project for a single developer to maintain.
I agree with the first part of your comment, about change being the natural default.

I disagree with the idea that we should seek to completely control every species' environment in order to avoid suffering. IMO, the goal of species preservation is a selfish one, but it's not to make us feel good. It's about knowledge: the more biodiversity there is, the more case studies we have from which to learn useful things.

From this perspective, constructing viable artificial environments implies that we either a) already know all there is to know, so keeping those species around doesn't make sense anymore (unless they're cute or useful in some other way) or b) those artificial environments lead to different behavior, therefore disallowing the aquisition of knowledge that could be gained from a natural environment.
I've been trying to get this article some attention on HN, but it's fallen flat the three or so times I've submitted it. "The case for nuclear propulsion for spacecraft (2003)": http://www.spacedaily.com/news/nuclearspace-03h.html

The article's points are (a) there were some realistic strides towards long-term sustainable space exploration before the Apollo project, (b) the Apollo project was directly responsible for canceling funding towards these long-term projects, and (c) the Apollo project was nothing more than a machine to convert a huge quantity of cash into a one-time use spacecar to stick a pole in the moon.

It was particularly surprising to realize that there are, in fact, feasible ideas for real space exploration. Humanity just has to remember and decide to pursue it.
>It would be profoundly counterintuitive if there were no clouds, or no cathodes, or no humans, and that is probably enough to reject the position

I really hate it when philosophers make "arguments by intuition". It's almost always used to justify denying some aspect of reality, or even worse, some ethical tradition.
How did you learn to understand what 'mundane' means?
Philosophically, I think you're right.

Practically, this is a problem that computers encounter whenever they are given an image and told to identify the boundaries of some object depicted in it. Instead of water droplets, we have pixels, and we have to figure out exactly which pixels are part of which objects (and to what degree, in case of partial transparency).

Having said that, I don't have high hopes that solving this philosophical "problem" will help us come up with better image processing algorithms. What we need is a scientific explanation of how human brains process visual stimuli, not a philosophical explanation of what we mean when we say there's a cloud.
> There are also plenty of studies showing the opposite, as well as studies showing trans people being, on average, somewhere in between the male and female averages (on the specific area of the brain observed - generally different in each study!). The fact is, we just don't know.

That should have been sex-atypical differences, which would accommodate for the "in-between" studies.

Taken as a whole, the science is pretty clear, when looking at various parts of the brain, patients with gender dysphoria (both prior and after treatment) show differences from cisgender controls, and typically, those differences align with those of their identified gender.

> And that's why GLAAD's definition is good. Trans people deserve respect and fair treatment regardless of what causes some people to be trans and others not to be trans.

These two don't follow each other. Of course transgender people deserve respect and fair treatment, like all people. I just think we have to be careful when we conflate gender variance with gender dysphoria - one is a very evolving cultural concept, the other is a major contributor to suicide in transgender individuals.
Take video or screenshots if you want. I'm not really interested in your story. I've got over 22,000 examples of why you're wrong in my library right here. They weren't purchased from Apple, and they're playable on all of my OSX and iOS devices via Apple's built-in apps with zero hassle.

Not all of them came from the same computer, either. They were added to my iTunes library over the years from several Macs and PCs. Some were ripped from CDs, some were purchased from other stores (Amazon, eMusic, Bandcamp) and some were downloaded from filesharing services.

I don't think you're lying. It seems like the root of your problem is that you selected "manually manage music and videos," but to be honest I'm not sure, because the defaults have worked well for me across quite a few computers and portable devices.

The gist of your argument seems to be that Apple makes you go through hoops to use non-iTunes music by default.

In reality, it works really well by default, and it seems like you jumped through some hoops to screw it up.
And as was asked in that thread, of all the human endeavors in which entire lives are spent and sometimes lost, why focus in particular on this one?
He's just trying to put a band-aid on the problem.
Once you have a function consistently used in your code the portable version can be used for the targets for which you don't provide an asm implementation, and the asm (or the solution customized to the compiler) can be selected implementation otherwise, covering the most common processors of today.

They spent billions of dollars on a dream that didn't pan out. And, in retrospect, was a bad idea.

And maybe a few hundred thousand on press junkets to hype the dream. Millions, tops.

Given that Alpha and MIPS dropped out before there was anything at all concrete, I'd say that hype was the one that mattered.

But I guess it's easy for me to say that in hindsight.
Since you are connected to their network they know your MAC.

What they will likely do is take your IP and look to which MAC their DHCP-Server has assigned that IP to. There are other possibilities though, but they are more complicated (using ARP-cache or requests, doing a raw packet dump at the webserver).

If you want learn more, I think you could read a bit about the different layers first, and then read about how ethernet, IP/ARP and DHCP work. There are likely no "headers" (I assume you mean HTTP-headers) they inspect.

I don't think it is, unless you pick and choose what you read.

For example,

Ruby is already very DSL friendly so writing something on top of it that at the end of the day just compiles down to Ruby does not provide the same kind of power/effort ratio as in the Python case. Plus there's already elixir which covers similar territory.
The issues raised by the fuzzy region between the well-defined genders is a complex one.

We tend, maybe especially us in the software world, to build systems that cater for definitions that neatly fit into specific boxes (M/F), or that rely on simplified models ("sex at birth is all you'll ever be").

Despite the fact that transgenders people have always existed, we are only starting to acknowledge their existence and recognise that they are citizen that have the same rights and duties as anyone else and that they should be treated with the same respect and consideration as anyone else.

I think we, as creators of systems that model the world, should be more knowledgeable and have more consideration for the complexities of dealing with sex and gender.

We can ask ourselves whether asking someone's M/F status is really necessary (what do we need it for?), whether we can allow at least a third option where neither are selected or present a perfectly valid "Prefer not to say/I don't fit in a box" option.

This also affects how we choose to address people with Mr/Mrs/Ms/etc. Allowing no title to be selected (or a title of the user's choosing) should also be possible, as well as selecting a title that doesn't traditionally fit with the selected sex (like choosing Mr even if the user selected F as their sex).

We then have to assume that these attributes can change over time and allow users to redefine them at will, without hindrance.

There is a lot more to be done but these simple steps, all fairly easy to implement, are a start in the right direction.

Because we can iterate more quickly and conquer space faster. In 200 years, if we do it my way we'll have far more humans living in space than if we do it a few humans at a time.

The point that you're completely missing is that I'm not saying that humans shouldn't eventually head out into space, it's that we should quickly interate our machines and other technology before we make the big push.
