Less competitive, at least in my state. The higher paying public school districts have a lot of applicants, who are often more senior and have either higher degree levels, or degrees related to the subject they would be teaching. The parochial schools are seen as being somewhat of a stepping stone for new teachers or those who are trying to get a foothold in a desirable location.
I use TechCU which is more prominent in south bay. I've had good experience with them for decades. They should be able to deal with recent immigrants given that they deal with the tech community. However they have just one office in San Francisco. But do shop around as you can get great deals (like $200-$300 bonus) for new members with direct deposit of your paycheck.

>the female brain is less capable of many tasks

That's a very problematic and dangerous phrasing. There is also no such thing as the female brain. There are distributions of biology.
That’s not how your comment reads. It reads as “well, we know how he feels, so keep that in mind.” Which, is an ad hominem attack.

If you didn’t mean it that way, than please consider that your word choices come across as mocking, which changes the received meaning.
Perhaps customer-oriented is closer to what I was thinking. Turns out you can also make good profits taking good care of them.
That would be considered passive aggressive messaging. People easily see through the intent. Just copy paste the content from the manual and link to source.
> People have a series of rationalizations. People say for example that science and technology have their own logic, that they are in fact autonomous. This particular rationalization is profoundly false. It is not true that science marches on in defiance of human will, independent of human will, that just is not the case. But it is comfortable, as I said: it leads to the position that "if I don't do it, someone else will."

> Of course if one takes that as an ethical principle then obviously it can serve as a license to do anything at all. "People will be murdered; if I don't do it, someone else will." "Women will be raped; if I don't do it, someone else will." That is just a license for violence.

> Other people say, and I think this is a widely used rationalization, that fundamentally the tools we work on are "mere" tools; This means that whether they get use for good or evil depends on the person who ultimately buys them and so on.

> There's nothing bad about working in computer vision, for example. Computer vision may very well some day be used to heal people who would otherwise die. Of course, it could also be used to guide missiles, cruise missiles for example, to their destination, and all that. You see, the technology itself is neutral and value-free and it just depends how one uses it. And besides -- consistent with that -- we can't know, we scientists cannot know how it is going to be used. So therefore we have no responsibility.

> Well, that is false. It is true that a computer, for example, can be used for good or evil. It is true that a helicopter can be used as a gunship and it can also be used to rescue people from a mountain pass. And if the question arises of how a specific device is going to be used, in what I call an abstract ideal society, then one might very well say one cannot know.

> But we live in a concrete society, [and] with concrete social and historical circumstances and political realities in this society, it is perfectly obvious that when something like a computer is invented, then it is going to be adopted will be for military purposes. It follows from the concrete realities in which we live, it does not follow from pure logic. But we're not living in an abstract society, we're living in the society in which we in fact live.

> If you look at the enormous fruits of human genius that mankind has developed in the last 50 years, atomic energy and rocketry and flying to the moon and coherent light, and it goes on and on and on -- and then it turns out that every one of these triumphs is used primarily in military terms. So it is not reasonable for a scientist or technologist to insist that he or she does not know -- or cannot know -- how it is going to be used.

There is no difference between a machine gun and a robot.

A person designs a machine gun but does not pull the actual trigger. There is an army officer that orders the weapon be deployed and the rules of engagement for when it can be used.

A person designs a killer robot but does not activate it. There is an army officer that orders the weapon be deployed and the rules of engagement for when it can be used.

There is always a person that is responsible for the use of a munition. Maybe that person is higher up the chain with a killer robot than a machine gun. If you want to launch a nuclear bomb then it goes all the way to the top of the chain. But there is always a person that is responsible for the death caused by the munition.
Ironically whole thing started with CIA staged double coup(first one did not work apparently) in Iran during 1953(declassified recently). It was so successful that they copy-pasted it to LATAM and elsewhere. [1]

Interesting fact: Kermit Roosevelt Jr. a grandson of U.S. president Theodore Roosevelt, played the lead role in the CIA-sponsored overthrow of Mohammad Mossadegh, the democratically elected leader of Iran, in August 1953. [2]

> What do you do after you get bored?

Anything else.

I'm not sure it matters. The boredom is the problem, not having options.

You could lock me in a room with nothing to do but read a book about thermodynamics, or study algorithms, and as soon as my interest starts to fade... my progress slows DRAMATICALLY.

What am I doing in this locked room, other than reading?? I don't know, probably just staring at the wall thinking about something else. Then realizing I'm wasting time. Start reading again... Lose track, get bored.... Stare at the wall and think about something else... Realize I'm distracted, start reading again... rinse, repeat.

Will get through an entire chapter, and barely remember what I actually read.
Like others have suggested, use git locally, there's no need for them to be involved or aware of that detail. Do you consult them on what text editor to use?

There's a skill to learn in keeping engineering concerns to yourself. It's unsurprising when management or executives are faced with decisions in unfamiliar topics they err on the side of Nay. Your mistake is involving them at all.
> injecting females with extra testosterone was just plain mentally disorienting

Reminds me of a study done about 35 years ago by the California DOT to measure the effects of both alcohol and marijuana on driving performance. Turns out teetotalers and non pot smokers suck at driving when given booze or pot. Boozers also suck when given alcohol but not as much. And pot smokers are barely effected at all.

I'm suspicious that the body compensates eventually, so acute effects don't necessarily tell you anything particularly valid.
I can understand those concerns. People I worked with used to give me some guff about always wearing a respirator when, really, they should have been too.

You really should be able to figure out pretty quickly all on your own if you need one and if it's working or not. But... you're right, and my own experience mentioned above confirms that.
Story time: when I was fresh out of college, I deposited a check to my Schwab bank account via mobile deposit, but realized that I wasn't going to have enough time for the funds to clear before I needed to write a check from my account to my new landlord. I called Schwab customer service, not really thinking that they would do anything, but to my surprise, the banker said "Let's fix this for you!" and suggested that we conference call the counterparty check's bank to verbally confirm the funds, at which point he manually cleared the funds into my account and told me "You're good to go!" Schwab has some of the best customer service I've ever experienced, even for new (i.e. poor) grads ;)
I’d recommend trying the graded exercises in https://www.coursera.org/specializations/data-structures-alg... or https://www.edx.org/course/data-structures-an-active-learnin... — unfortunately, for the most benefit (online automatic grading), you’ll have to pay either EdX or Coursera, but EdX offers a small sample of exercises to start, if I recall correctly. And there are a few more courses after those.

If you’re anything like me, you’ll learn better if someone doesn’t ask you to do the impossible, but instead leads you through enough solutions that you can get an immediate confidence boost from the first few easy ones, then the intermediate ones require more thought, and if you really get stuck, there are discussions about how to solve some of the problems. Usually you have to think algorithmically, not just write code, and some problems might just be harder for you to understand because you haven’t done as much work in that area. I won’t say it’s a complete look at algorithms—there’s a whole other course on strings if I recall, but it’s a good start.

Also, here’s my cheat to pass those employer questions — if they let you use JS, do EVERYTHING you can with ES6 Map and Set classes. Folks rarely look at the code and don’t care if you’re using for loops or advanced classes, but it’s way easier to use a Set than to worry about how many times you have to loop over some result to reduce duplication, or sort things, or what have you. If you need a unique sorted set, there are faster algorithms, but a simple (new Set(arr.sort())) gets the job done, because Set is insertion-ordered by default and any native JS function is generally faster than you writing your own code, so it’s impossible to mark this solution as wrong unless you exclude native functions (but who does that?). A bonus tip, if you need to figure out the difference between sets, just get creative with .filter and .map. There’s not much to memorize beyond that because there’s not much advanced functionality, just building blocks flexible enough to do anything, relatively expressively. https://exploringjs.com/impatient-js/ch_sets.html#missing-se...

I'm really surprised about the gender focus here, and the fact that neither of you have answered any of the gender questions raised so far. Why not build for both genders? Do you have data suggesting that a) older men are not lonely/want community b) older women do not want to be around older men or c) something similar?

I agree that this is a dramatically underserved market, but I am unaware why women are particularly underserved than men.

Or is it just that men deserve to be lonely?
> Straws are a very small part of that and a weird thing to fixate on relative to all the other one time use food waste we generate.

People always fixate on things they personally touch and see, over things that are out of sight even if they're thousand or million times bigger factors.

Thus all the frenzy around straws, shopping bags, coffee mugs etc.
That's progressive enhancement.

Progressive Enhancement: Starting from some baseline, ideally static content, and building in features that newer, usually visual browsers can support

In what ways do teachers' unions campaign to give agency to students' families and career choice to in-demand faculty?

Seems like the incentives are mostly oriented around getting teachers to stay in one place and grind out another year of experience, round of continuing education, and extra degrees whether they are wise or not.

Otherwise, why don't teachers just quit schools with poor safety records, working conditions, pay, equipment funding, and uncompensated overtime? Because no district really has to worry about being held accountable like that.

Recently quit working at C1 as well, and share the author's sentiments exactly.

Whenever I brought up whether the work we were doing might actually be harmful (even as a general question), coworkers would reflexively quip about what they're doing giving back to the community through outreach, or some other vague response that obfuscated the people behind the problems they were solving.

And of course, executives would just spam you with "Change Banking for Good".

I couldn't stand it.

As someone alive and paying attention to that period in time, I got the impression the "for oil" thing was generally hyperbole never explicitly stated but probably loosely true right since the VP was an oil guy.

Except that American oil companies didn't get any benefit so how does that make any sense? If we are willing to accept the evidence that oil companies in the US didn't meaningfully benefit, doesn't that whole argument kind of seem silly?

It's bad enough that we invaded under pretenses that really really really should have been obviously incorrect at the time, with no plan, just... I don't know. It seems unnecessary to even bother linking it to oil. It was evil. It was stupid.
> Ohh, and build times are like 40+ fucking minutes on a good day in a fast machine.

Reminds me one of my past colleagues who worked at some_proprietary_compiler with so many tests for corner cases that it took 6 hours for each build on a top enthusiast grade PC each person in a project was provided. Also the presence in office for 8 hours a day was mandatory, imagine the whole team spread around the place for the most part of the day doing nothing with an excuse "I'm compiling!"

If anyone is interested in a bank built for startups, also worth a mention is Mercury.co. Been using them since their alpha, and I'll never use SVB or Wells Fargo or any of the traditional banks again. They have obsessively good support, do everything you need them to do without having to go into a branch, are backwards compatible for everything you need from a bank account, you basically just set it and forget it, and best of all it's completely free.
A follow up, if ES6 JS doesn’t come easy to you — pick a language you like best and look for its equivalents to Set, Map, .filter (or select) and .map (or collect). Bonus tip, look for .find or .first, to short circuit looping and stop at the first thing that matches. Yes, you can memorize for loops or why one thing is more efficient than another, but if you start with Set and Map where each makes sense, you’ll solve 80-90% of algorithm questions pretty easily and usually in a way that’s straightforward to read and understand later, especially if you start naming some of your functions to make them a bit easier to read. (Like naming selectors in Redux...)

If writing SQL as part of a quiz, learn the different joins because usually the question is worded in a way where picking the correct join will deliver huge performance benefits by reducing how much data you’re going through or making things more efficient than looping through multiple subqueries. Left vs Inner vs Right vs Outer vs Cross... remember that the less data the server has to go through (the fewer records in the earliest sub query), the faster everything will run, in these quiz scenarios. Yes, in real life how you store data matters, what you index, but it’s rare you’ve any control over the index or schema in these tests.

I think it's right to say you can't rely on those older methods, but there has been a lot of research that's gone into DPI bypass. The HTTP Evader work that's been done is particularly good [0]. In some cases the guarantee of operating a VPN over a hostile network isn't guaranteed, especially something like IPsec. So it's good that the simplistic fragmentation methods of tools like fragrouter have been expanded on.

In the case of the DS at least, the big differentiator is that the second screen is touch, and is positioned in a more touch-friendly place.

If your one-and-only screen is touch, you have to lift your arms up away from your buttons to press anything. No matter how much of an impost it is to have to look down a little, I'd say it's still less than having to lift your hand away from the buttons into your eyeline.

> All of these groups in Western societies have been, and often still are, dominated by men.

But not by all men. If all of the top 1% are men, for instance, there are still 49% of men out there that are both make and not elite.

Ask HN: Who are the major players in the digital advertising world?
I've recently gotten into the digital advertising to advertise my own business, and I was wondering who the big "players" in this world are. A few are obvious:

* There's advertisers like me, who pay money for advertising.

* There's large content-based sites, from Google, Youtube, Facebook, Amazon, to smaller ones like Quora and reddit, where you can pay to get your ads placed directly

* There's third party sites (not to mention things like games) that run ads through display ad networks.

* There's an entire world of affiliate marketing where people try to sell other people's products for a cut.

* There's "influencer" based marketing, where major brands pay e-celebs to show their products, though I guess that's more traditional than "digital" marketing...

Who else is involved? I feel, given the sheer size and complexity of the advertising space, there must be more companies out there. Is there a secondary market for google adwords? Are there 'hedgefund' like companies that make proprietary bidding algorithms?
I'm curious, do they have an option for automated/recurring investments? Like can I set an account to purchase an ETF on a schedule?
