This problem is due to the laws of physics rather than bad product design, however. There is no battery technology that would scale to a car and not self-discharge. Yes, the thing discharges to keep some systems online, but even if it didn't, the battery would still brick itself over time.

The iPhone is a mass market product with millions of users. Tesla's cars are experimental products for early adopters, with a few thousand users. Completely different situations.
Old topic. Salient talking points:

1) "Geek" culture is not heterodox. It's very accepting of fat guys who like faux-Mexican food, and anime; but not so accepting of other non-conformists. Many women are not fat guys who like faux-Mexican food, and anime.

2) Women are encouraged to work hard. Men are encouraged to be talented. This is true of teachers, parents, peers, and managers. Coding is something that requires more talent than hard work (at least, to get started); due to the high barrier of entry.

3) There is some ugly sexism in parts of tech. There is ugly sexism in other career paths (finance, sales); but we can do a lot better.

4) Some women choose to have more personal time, rather than staying up till 3am coding. It's hard to tell if this is really relevant - Patrick McKenzie claims to have run business on 5 hours a week. And no-one here (I hope) think driving code monkeys on 80 hour/week death marches is really a good idea (due to tiredness-induced bugs).
Specifically, they seem to be looking for bachelor of science grads, not arts. Also, you have to carry your own insurance. I'm assuming the class 2 flight physical should pare it down to fairly healthy specimens anyway. Hard to believe people who qualify aren't already employed; they may need to up the ante.

This is the "Learn X the Hard Way" book I've really been waiting for. Thanks, Zed, for the time and effort on this one. It's a topic that schools seem to completely ignore for some reason, but a skill I find I use on nearly a daily basis.
I don't think it's just that the performance case for middleware has become weak. It's also that traditionally you pay per connection some sort of license fee. So if you are running Oracle or SQL Server, and you want to add additional clients that, say, do additional process on notification, that means additional license fees. This isn't a problem on PostgreSQL.

It means there are choices between the traditional ones of putting everything in the database or in the middleware.
Gruber makes an assumption that the only thing that third party cookies are used for is ad networks and tracking. A whole bunch of common (especially the new social tools) you use rely on third party cookies.

Its not 3rd party cookies to blame, its their use. There are legitimate uses for third party cookies. If I care about blocking ad networks, I use an ad blocker. I just dont go ahead and limit the functionality that these cookies offer.

There is an article on how to do it: http://support.mozilla.org/en-US/kb/Disabling%20third%20part...

That's probably the reason.

I'm guessing that MS is using the cookie for a purpose that it was not intended for. That's not to say it's inappropriate, but it's up to them to understand the risks and make sure the app works in both states.

I disputed the notion that programming required "talent", whatever it means. Learning to program isn't rocket science, but it required a lot of dedication and patience.

Some women choose to have more personal time, rather than staying up till 3am coding.

I thought coding until 3AM in the morning is the definition of personal time for programmers.

> A browser using Spdy could indicate it supports deflate to enable compression.
This would cause everything on the connection to be compressed. Including things like images and videos, which are already compressed, and likely as not, will get larger when you recompress them.

> These guys do testing to confirm their assumptions.
This is how any science gets done... hypothesis, then experimentation

As to your comments on how compression works, I admit my lack of knowledge on how lz works. But I trust the results of the experiments done by the guys at the University of Delaware. If you have a better dictionary in mind, take their sample data, run the same experiment with your dictionary, and post your results on spdy-dev. That's how they got their change in the spec in the first place.

> ... but as protocol designers from Google the work done with Spdy is just unacceptably bad.
Any actual examples? If you had any real basis for your arguments, I'd be more than willing to back you up on spdy-dev.
I don't think the problem is numerical parity. This is wholly anecdotal, but I've found working in mixed-gender groups is more pleasant. There's less of a tendency to goof off/take on a frat house mentality when the programmer team isn't all-male.

Statistical tools can allow for control. The best paper I've seen on this is the Romer and Romer study "The Macro-Economics of Tax Changes."

Every dollar in food stamps comes from a dollar of taxation. Their study shows that the multiplier of the original dollar is -2.5. If we have 1.8 multiplier on the food stamp, then additively we have -0.7.

Alternatively, every dollar which is 'spent' by the government in the form of tax cuts has a multiplier of nearly 3.

"The fact that the work of Shakespeare is probably the work of a group of writers working under a pseudonym adds further irony to the work ... but it is also entirely disputable that he existed at all or certainly that he was one person in fact, one commonly held view is that he was an illiterate actor and a consortium of writers used his name as an ironic joke."

The site is filled with crackpot arguments like this and other mumbo-jumbo, e.g. "emphasises [sic] the unreliability of human (scientific) hypotheses" which is a pity because this is a fascinating subject.

A much better time investment would be to read The Library of Babel by Borges, if you haven't already done so. Then, buy The Unimaginable Mathematics of Borges' Library of Babel, which is truly excellent.
According to the website, "They hope to monetize their product by selling their simple communication system to school administrators".

So this chart shows an increasing number of non-monetizable members... and doesn't show growth in their core product / revenue stream: a paid communication system for school administrators.

This situation is very similar to the whole Groupon subscribers issue - which has proven subscribers aren't necessarily monetizable, or a very small / disproportionate members are...

Thoughts on reporting growth of 'users' vs. growth of 'monetizable users'?

Are any users worth anything, even if they aren't related to the core product?

This is an interesting idea, and I think his final analogy summed it up perfectly: symbolic math is like a command line. But I reject his assumption that a command line is a bad interface. And that mirrors my thoughts on this post: for the layperson, a GUI may indeed be better than a command line; for a professional (a programmer) the reverse is true.

A command line lets you combine and recombine different programs and easily do many things its creators never dreamed of. Symbolic manipulation and algebra are just like that!

Let's imagine you know how to differentiate viscerally; you understand what a tangent line looks like and how to plot that and you care not for silly equations like d/dx x^3 = 3x^2. Naturally, you understand basic arithmetic in the same way and not as mechanical manipulations on symbols. You are perfectly well equipped to deal with real problems, and perhaps find it easier than shuffling symbols around. But you would never come up with a way to get the derivative of, say, an algebraic data type[1][2]. (For the curious, this is how you can define a zipper on a type.)

[1]: http://blog.lab49.com/archives/3011
[2]: http://strictlypositive.org/diff.pdf

And that's the problem really: mechanical manipulation of symbols lets you divorce the mathematical idea from the underlying "reality". It lets you generalize patterns with complete disregard for what they mean. And, somehow, this produces indubitably useful, nontrivial results. That's the real magic of math, and that's the magic that you don't get in your high school courses. (I think linear algebra is the first subject like this, but I'm just learning it now.)
It depends where the dollar comes from. If the dollar is from taxes, it not only destroys the dollar but nearly two others along with it. If the dollar is from borrowing, the result is better. But if the dollar is in the form of tax cuts, then it ends up creating more good than bad.

As I've quoted elsewhere, this is from the study by Romer and Romer.

Both journalism and "journalism" are meta-games. They don't really track where the industry is -- they track a separate and not necessarily representative alternative advancement system. You earn journo-points in an entirely different way than you earn geek-points or engineering-points or startup-points or money-points. (P.S. All of above available independently from each other, too.) The criteria for awarding journo-points are set a wee bit by fashion, a wee bit by tradition, a wee bit by merit, and a whole heck of a lot by the desire of journalists to have power and privilege and the desire of media outlets to have the opportunity to sell the attention of people who have high purchasing power.

If one hypothetically wanted to get ladies more journo-points, one would not tell them to improve their coding ability, because the ROI on coding ability in producing journo-points is pretty poor. I don't think most people are really interested in the social justice maximizing allocation of journo-points, though. (n.b. There are a variety of activities which are worth zero or negative geek-points that are worth scads of journo-points which I could use as an example here. I'm self-censoring because I don't want to accuse the folks on those Top X Lists of benefiting from them even though, in aggregate, they certainly benefit from them.)

I would be very careful making inferences from present allocations of journo-points into how we can better incentivize any group of people into seeing that startup-points or geek-points or engineering-points are what they should be optimizing for, if we decide that that is indeed our goal. (On the specific subject of gender, I think that at least part of the discussion should probably be "What kind of points do women at the margin want?" and, if that isn't geek-points, "Should we convince women at the margin to sacrifice what they currently value for geek-points?")
I disagree, in that I also think it's a terrible experience to have to put up with commercials.

There's thinking something is bad because it's different, and then there's thinking it's bad because it SUCKS. I grew up on commercial TV. Now I can't stand commercials, and I think HULU is absolutely insane for not having a "no commercial" tier -- and for charging you and STILL running the commercials.

I would SO rather pay for my media than have commercials interrupt it. It's not a kid being uncomfortable with an unfamiliar situation; it IS annoying to have your program interrupted.

And I'm not even militant about advertising -- I don't run ad blockers, and I even click on ads from time to time. What I can't forgive is people wasting my TIME. I have a finite amount of that (and why am I posting on Hacker News..? sigh...), and people showing me ads for things that I have ABSOLUTELY no interest in is nothing but a waste of my time AND their advertising money. HULU has a little button where you can tell them an ad isn't relevant to you, but it seems as if they ignore it. What a waste...

I had a pretty embarrassing meeting after opening a blog in Safari plastered with lingerie ads during a presentation. Near as I can tell, my wife opened mail from them in GMail and that was enough association to serve the ad.

So, who is to blame? The ad service for serving something inappropriate, my browser for having a bad default privacy setting, or myself for not changing the privacy setting and lending my wife the laptop to check her email?

No more 3rd party cookies for me. It's rather shameful that these ad networks have seen fit to work around a sensible default. It's worth a mention that this isn't new - flash cookies have been a workaround for ages.

This is interesting, I especially like the Scrubbing Calculator. While I am not sure how it would handle math above Algebra 1, I think this could be great for building intuition in Pre-Algebra and Algebra 1, which are the most important years of math education, in my opinion.

I tutor some 11-14 year-olds who are studying these sorts of things, and it's incredible how many of them can look at something like 100/0.08 and have absolutely NO idea what neighborhood the answer should be in. (For example, they might accidentally multiply, get 8, and never think twice that the answer couldn't possibly be 8 because it has to be above 100.) Something like this might be really helpful in building intuition about the relationships between numbers.
> Gruber makes an assumption that the only thing that third party cookies are used for is ad networks and tracking.

I think it'd be more fair to say that this particular use-case is the one that he's emphasising. And, in the context of privacy, it's the one that regular users are going to care about the most.

> If I care about blocking ad networks, I use an ad blocker. I just dont go ahead and limit the functionality that these cookies offer.

That might work for you, as an individual, but Apple couldn't do it without copping a lot of flak. Imagine if they suddenly blocked ads by default—the web would go crazy.

I would posit a guess that there are more sites out there that need ad revenue to survive than there are sites that need third-party cookies to survive.
This post may not seem very PC but here it goes.

One thing to point out is that historically women have had different economic priorities than men, and usually still do. In the Wild West for example, for a long time, there were 50 men to one woman, roughly the same gender ratio as in the early days of the internet and in open source software engineering today. When we see these long pervasive questions, it's worth asking why. Certainly gender roles have changed enough since the early 19th century that this can't be the only factor, or have they?

At least in Western history, women have historically (and continue to today) looked for more security than adventure, and therefore tended to be very under-represented in cutting-edge fields and immature industries, while moving in later as things begin to stabilize. Women have historically run safe industries involving commodities everyone needs (thread, yarn, cloth), and take fewer risks.

So my take here is that the start-up culture itself goes counter to what most women generally want: a stable supply of income structured in a way which is friendly to raising a family. This is a bug, as you say. But it cannot be solved with a little outreach or so forth because if more women wanted to be involved at these early stages of startups, they would be.

A better approach IMO is to look at how something like open source software consulting and development can fit into a more integrated lifestyle where work and family life are no longer separate. This brings women into tech but on terms that are more in line with current career trends of career choices that women not only are making today but have in the past. This means focusing on economic opportunities which are conducive to this sort of integrated lifestyle and worrying less about CEO's of hot startups.

I am also going to make a claim that may seem even more controversial: I am willing to bet that women are more likely to be self-employed than men, and that there may be a lot more women in tech, self-employed, than we know. We may simply be measuring wrong.
Programming has a high barrier to entry? I've always assumed the opposite: it has a much lower barrier to entry. All you need is a computer and you get immediate feedback (e.g. does your program work). So it's easier than anything involving making physical stuff--no need for materials or tools or expenses, and it's easier than other mental pursuits like math because you can tell if you're going in the right direction and it's easier to do useful/cool things immediately.

> I thought coding until 3AM in the morning is the definition of personal time for programmers.

I do not know about most programmers but personally I stop coding at 10pm. Any later and I'd be damaging a well balanced sleep pattern and writing sub-standard code.

Instead I think the cause is something similar. Girls historically did not spend a significant amount of their free time on computers. Interestingly enough I think that is changing. Nowadays thanks to facebook both genders spend a vast ammount of time at the keyboard.

Whether that will result in more female programmers I'm not sure. With video games the natural next step is to try and make your own. Facebook does not have this natural migration path towards programming.
It's funny...when I read that bit, all I could think was, how much nicer would it be if regexes could just be written without the special characters, using sane word-based self-documenting tokens the way we do the rest of our programming, following scoping and quotation rules that actually mesh with the languages we're using them in?

Then it occurred to me that plenty of people have probably written libraries to do exactly that, but nobody uses them because we all already have regexes built-in almost everywhere that we want to use them. Hell, I've never even looked for one, even though I choke back a little vomit every time I introduce a new regex into a codebase because of how much future debugging pain I know they can cause (all but the shortest ones force what's essentially a full context-shift in order to parse, and in reality what usually happens is people scan a regex as one chunk and say "Eh, a regex, it's probably right, hopefully my bug is somewhere else..." until they have some concrete reason to think otherwise).

Sort of a shame, really, that such a problematically condensed syntax won the prize so early on, and now even those of us that hate it are too comfortable with it to look for something better.

There's a generation of female coders coming out of NYC soon -- seeing half my Nature of Code in Processing class being female and a lot of my female classmates working with OpenProcessing, Pocode, etc. Likewise in DC there are already a lot of up-and-coming tough-as-nails journalistas starting to run stuff. I think they're a little further ahead than the female coders right now though. You'll see this stuff happen in east coast cities first since the ratios are so favorable for highly-educated, intelligent, fiercely independent women there.
