Think in terms of magnitude (which can be positive or negative) and direction.

Think of a scalar. It has a magnitude but it doesn't have a direction. It's 0-dimensional.

Think of a vector. It has a magnitude (the size of the vector) and it also has a direction, which points in a straight line through the origin. It's 1-dimensional. For example, the vector (2,0,0) has magnitude 2 and points along the X-axis. You could write that as 2 * x, if x is the vector (1,0,0).

A bivector also has a magnitude, but instead of being 0-dimensional (like a scalar) or 1-dimensional (like a vector, it's 2-dimensional. So you could have a bivector that "points" along the entire XY-plane (remember: two-dimensional) and has some magnitude, say, 5. You could write that as 5 * x * y, if x is (1,0,0) and y is (0,1,0).

If you attach physical units to these things, then you might have units of meters for vectors, and square meters for bivectors.

Having an understanding of subspaces in linear algebra is helpful.
Interesting. Still, that requires the attacker to be already running a process on the victim's machine, even if with reduced privileges. Nowadays that's rare, since there's no reason not to give each user its own network namespace, at the very least.
I fail to see what's wrong with this: it's open-source, and anybody can write different libraries, or libraries that use all the low-level work ($$$ paying experienced/skilled engineers) that Google pours into making tensorflow.

Alternatives exist (PyTorch by facebook, theano, caffe, etc.) in any case, and the best solution wins. (in the same way scikit-learn once eclipsed all other ML libraries, but some would still use xgboost which had superior Gradient Boosting Trees).
Totally agreed. I find the notion of the so-called "soul-mates" a bit absurd. People behave differently when around other people, which means they can adapt to others. Being compatible with each other is a quality which resolves many issues.

I remember a few years ago, I read somewhere that the best girl you should marry is the one who if she were a guy, she'd be your "best friend".
Respectfully, your argument doesn't hold water because it doesn't look like you understand what being/falling in love is. Sexual attraction is 70%-90% visual appearances and mostly biological, but falling in love is not about sexual urges, it's about happiness. We fall in love with the person that brings happiness and joy to our life by merely spending time together, not necessarily the one we want to ram our genitals into.

Most people pursue partners based on sexual urges, sure. But falling in love is a whole other game, and they don't go hand in hand.

Depends on how recent the burn was. Within a year, maybe two? Perhaps. After that? Plenty of new trees to chomp down on.

And unless explicitly directed, forest fires rarely create anything that could be considered to be a "break" between two sections of forest. Usually more like a "blob" in the middle of a forest.
I like this view on it. I can't disagree. I was just saying that there is some merit to being called "evolutionarily broken" for not wanting children. Whether you think that's good or bad or meaningless is another issue
I'm not a conspiracy nit (for that conspiracy anyhow) so I'm not going to try to answer those very good objections. I have no idea how it might have actually worked, if at all.

You assert that there's a magical unbiased optimization mechanism. There is not.

You then assert that women will do equal work for less money than men and then make a bunch of inferences based on this, ignoring multiple faulty aspects of the assertion in the first place.

The fundamental disagreement we're having is whether society is biased in the first place. You are making a bunch of analyses and logical inferences about social behaviors of people, but all of the things you are analyzing are fundamentally embedded in a biased culture. By contrast, the people you're arguing against are trying to change the culture that you are making analyses in such that we can actually use analyses like yours effectively. We claim that right now, we cannot.

The evidence suggests that "there are fundamental social biases against certain groups resulting in their disadvantage" is an explanation that better reflects reality than biological pseudoscientific assertions. See several of my links above, for instance citing studies that indicate that men judge women's competence based on appearance.

Thus, seeking to eliminate those biases is a goal which will result in value.

Twenty n is a new one on me, it was always n thousand in my hide and seek days, but it seems there are so many variations - n hundred, one thousand and n, n Mississippi etc. - with such a wide range in length of modifier, each spoken with its corresponding degree of rapidity, that I wonder if it's more a case of tapping into an instinctive feel for the length of a second, with the modifier word just helping focus the mind on the matter.

Depending on how you define the money supply then you could say that the total supply of the US dollar is around 12 trillion dollars (based on M2 money supply.)

Given that bitcoin has a hard-coded cap of 21 million coins, if bitcoin became a reserve currency of the importance the USD currently has, you could assume it would reach a market cap of 12 trillion, meaning each bitcoin will be worth $570000.

The reason the USD value has not spiraled to $5000 each is because the economists advising the government believe in inflationary currencies, and believe for some reason that the best thing for a currency to do is to devalue by 1-2% each year. They give some reasons for this which, like a lot of economics are driven by conjecture and not evidence-based. Money is printed approximately to achieve this target, however in recent years, 4 trillion dollars has been printed and given to banks, again based on very little other than economic conjecture. I'm not going to argue with proponents of this sort of economic theory because its a waste of time, however I am glad that a currency not linked to a nation state is going to be able to challenge all of these assumptions.
I'm aware of the practice, but haven't specifically sought out fire stick farmed areas to travel to. I'll have to check some out.

The literature you've read is _probably_ mostly focused on the Rural Fire Service (RFS) HR program. Their focus is protection of life and property in settled areas.

The land management burns are undertaken by National Parks and Wildlife Service (NPWS). RFS often assists with these to provide extra manpower.

I imagine the various State Forestry agencies also have similar programs, but I don't know anything about them.
Roads don't do much to stop wind. I've never seen many man-made wind breaks which weren't directly related to stopping snow drifts in specific areas.

Balance the inconvenience of service interruptions with the cost of reducing the interruption.

Engineers and other staff can work at weekends / nights / popular vacation times / public holidays, but at an increasing cost. There's also a limited total number of engineers, so it will help to have a steady amount of work (i.e. permanently employed staff).

Thanks for clarifying. Is it fair to say that you disagree with the author on whether the biological differences exist (and if they do the size of their effect on representation), not with the logical merit of the argument (group aptitude and preference affect representation)?

I can understand that position and think we can call it a day as i don't feel qualified to argue the size of the effect. It could very well be just 1%, i.e. 49/51.

If not

> "raises into question the fundamental capability of every woman he works with"

> The author makes the claim that one sex's ineptitude in a modern role is, on average, rooted in biology. That's not supported by science.

This does not follow from your argument.

Your argument only supports that the author questions the ability of every women who fails to get a job in the field / that modern role.

If it is proven that biological differences do not significantly impact modern role preference and capability, you and the author agree that representation should be 50/50. He never specifies how much of an influence he believes biological differences to have, just that there could be some.

I also disagree with your assertion that the author questions any individual womens aptitude based on her gender. He is talking averages across the general population, not applicants after all.

> As to "aggressions", I would challenge anybody to find a quote from the memo that could be considered aggressive.

The entire premise of the manifesto is that one third of the company only has a job because of their gender. In what world is saying to thousands of people "We only hired you because you don't have male genitals" is not an aggression? Maybe it's not to people who don't give two shits about their work, or their accomplishments at it, or whether or not they'll have a job next week. Most people aren't in that category.

Has you ever been in that kind of situation? Where somebody reduces your entire justification for existence to the color of your skin, or which chromosomes you've got?

Those months weren't "lost". There's no shortcut to learning idioms, best practices, and — more importantly — understanding the most natural way to model a solution in whatever language you're working with.

Sure, read books and blog posts. Test things. Learn debugging tools. But nothing really substitutes for actually working with a language. Having an experienced mentor helps, but only if they're advising you on why they chose a certain approach, or why a critiqued approach you chose was bad.
The problem is bringing up biological differences (even just in terms of groups and allowing for lots of individual overlap, and even in this case, when the differences aren't nec better or worse, just differences). It's a non-starter to many people, particularly on the left (see the Bell Curve).

One the one hand, I sort of get it, given historically people have used biology/similar arguments to justify a lot of awful things. If Hitler was around now, it'd be sort of disgusting to ask people to engage his argument on its merits (this is where some of the Nazi language re: this manifesto comes in I think).

But, when it's presented like it is here, making clear that individual variation is much greater than differences between groups (e.g., he's not talking about existing female engineers at google or anyone else in particular), stressing that diversity/human dignity/worth etc are all paramount even if there are group level biological differences/trends. Then I think the lynch mob/monoculture/not engaging reaction is in the wrong, and the reaction to this very much proves one of the guy's main points. But that's my two cents.
US government military is so much better. Skill fade is brutal. The US military spends a fortune training and exercising and refreshing and retraining, over and over. Mercenary companies simply don't have the funding or facilities to do the same.

Typically, the employees are contractors. Some of them might still be in date for some of their professional qualifications, some of them might be years or even decades from their last professional military refresher. I'm sure they can get by swapping tips and visiting gunranges, but it can't compare to spending nine months of the year on exercise or deployment.

"White privilege" aka modern civilization. Considering the entirety of modern civilization and inventions were made by white people, everyone lives in the glory of white privilege, even minorities living in america.

I have an idea, if you truly want to get away from "white privilege" how about you go into the forest and start a new civilization from scratch but this time without white people.

Surely it would become a paradise in no time because you wouldn't have the white devil holding you down?
I'm a lead on a team of 13 right now: myself, 6 developers, a QA lead, 2 testers, analyst, scrum master, and product owner.

We're one of ~15? teams in my organization (part of an overall IT shop of ~3000), but we're fairly separate from the others in business and technologies. We have a delivery manager for our team and a couple other efforts. There's a dedicated tech lead of tech leads, program level PMs, lead product owner, 2 architects. There are also some other folks from the business side, change management, etc that we work with regularly.

We're going through a bit of a change at the moment, removing the QA and analyst roles, spreading scrum masters across 2 teams, and limiting team size overall. So by the end of the year, I expect to have myself, the product owner, analyst is moving to scrum master, 1 QA as developer, 1 QA maybe as developer (we'll see how he adapts), and 4 developers.

It is a really big organization with dedicated departments for security, security testing, application security, performance testing, accessibility testing, brand management, change & release, test data, DB, DB security, gateways, shared components. And those are only the folks I interact with - there are mainframe folks, server maintenance (linux and windows), and the list goes on.

Some of that is moving to the teams now, some later. It's a pendulum though, things will be more generalized and distributed until something breaks spectacularly and someone will ask "why don't we have dedicated testers? why are we trusting every ol' dev with DB access?" and so on.

Hackethereum. The first truly honest Ethereum ICO – 100% guaranteed to be hacked
Word of advice: the 'jq' tool for handling JSON files (couple with a glob like '*.log' or something fancier with xargs or parallel) will absolutely save your bacon in those situations. It's way more powerful than it appears on the surface.

We had a series of Docker json-file driver log files. It's done as a raw list (no array around it) of JSON objects -- which is a bit annoying to sort and filter based on properties of the objects.

'jq '[inputs]' (asterisk).log > combined.json' was my favourite command today; it combines all the files inputs and wraps them in an array correctly. No awk needed!

Combine that with its cute:

jq '.someProp as $var | test("some search"; "gi") as $r | if $r then ($var + $__loc__) else null end' (asterisk).log | grep -v "^null$" > filtered.json

And you're away to the races. Can then load the file directly in and group_by(.somePath) and it will all magically work!

Edit: had to remove the actual asterix symbols as they screw with formatting but are used for globbing the file names. Replace with the real character
Hi HN...

This started as a joke that occurred to me last week when I was thinking about the current fad of the Ethereum ICOs that seemed to have little substance or be blatant scams. Well my brain took that to its logical extreme and this is what I arrived at.

I obviously couldn't pass up the excuse to try writing it.

Learning Solidity has been an interesting experience. While it is visually like JavaScript, that is where the similarity ends. It's statically typed for a start, and having to reason about an entirely new form of execution model is quite a challenge. I'd encourage any devs with a passing interest in blockchain tech to give it a try.

so "black swan" is a paradox. a black swan is when something that happens outside of the models. it being in YOUR models means it wasn't a black swan for YOU.

as such there are probably no such things as black swan events. I mean, until there is. Its more like Schrödinger's swan.
People should just follow math and the optimal marriage problem, if they want to get married. This probably operates in phases as well in the event you do get divorced. Early adulthood, middle age, later. This may skew in NYC due to older NYC men when they want to marry and have kids can find a younger women.
I enjoyed this talk.
I agree about getaddrinfo(). Applications should have specified AF_INET to gethostbyname() and then when updating to getaddrinfo(), handle ipv6 correctly or skip it.

The IPv4-mapped IPv6 addresses thing is a terrible idea that ends up turned off everywhere it makes a difference. Like all of these "transition" ideas, it tries to help, but it just hurts by causing admins/ops/devs to just make sure ipv6 is off everywhere they run into it.

If all IPv6 was just opt-in everywhere, we wouldn't need all significant applications to detect and work-around broken ipv6 (in the local network, in the ISP, in the server, in the peer application). If IPv6 was only explicitly enabled, and fully consciously handled when it was, then practically everything would have opted into IPv6 years ago. As it is, things started getting IPv6 support around 2005/2006, and then disabling it around 2007/2008 because it was fake/broken ipv6 in too many places (windows teredo, 6in4, etc).

OS X had to disable IPv6 in one release and then re-enable after implementing happy-eyeballs in everything. Firefox had to do that. I know about these cases in particular, but I bet all significant network applications had to have a bunch of "detect broken IPv6" code added. Major websites had to disable IPv6 on their main domains (and sometimes added an "ipv6." subdomain). The reason was that some people had broken IPv6 and their computer would try to use it to access their site and fail (but other ipv4 only websites worked). Things are getting better now, but it was a 10 year set-back. So much time and effort could have been saved if people with good-intentions didn't add automagic transition technologies and just waited for IPv6 to be explicitly added on both ends.
If anything, the proposal corners people into more hardcoded behaviours.

> Which means he is actually questioning whether an entire gender deserves to be allowed to be engineers.

No, he is not, and your choice of words like 'deserve' and 'allowed' to add intent that wasn't present in the original is unfortunate.

It's NOT a question of 'permission', so it's not about who is allowed to be an engineer and who isn't. He is specifically questioning whether positive discrimination to ensure there are equal numbers of men and women engineers at Google makes sense, if there are innate differences in the degree to which men and women DESIRE to be engineers.
the best solution wins

Minor quibble, but: not really. The earliest solution wins, e.g. rails. It has to be good enough, but after a certain point "best" stops mattering.
Surely you have some irrational beliefs that make you happy and make your life worth living. For example, since you got up this morning, it's evident that you feel living is worthwhile when in fact all evidence points to the fact that death is final and life is meaningless. It seems pretty silly for you to listen to your lizard brain telling you to try to stay alive each day. You get hungry and your brain tells you to eat, and lo and behold you eat food and survive. What a coincidence!

Anything other than pure nihilism is a conservative notion should be marginalized.
