So this clearly shows that boys are much better at math than girls. Period.

Or not.

Sometimes I wonder if these competitions (or the real Olympics games for that matter) lead to a more racial/social prejudice, rather than diminishing them.
>For the record, my Appalachia town also had good schools, though we had more than our fair share of meth and poverty as well.

Good on you. We had the poverty, although weed was the favorite cash crop, rather than meth. Growing some plants out in the woods is easier to hide than a lab that might blow up and catch the double-wide on fire...

Immigration is a zero-sum game. Americans should be proud when they can poach the best.
There are legal limitations on exercise windows for ISOs that complicate matters (trickiness involving NQO conversion) that must be accounted for even in your "simple" solution (ask your attorney). It's a shitty situation for companies that want to do right too. No one wants to innovate on corporate structure (time, cost, and headache) when you're already trying to solve major product market fit problems...
Check out the book "Working Effectively with Legacy Code", by Michael Feathers[0].

I believe the basic approach is to write tests to capture the current behaviour at the system boundaries - for a web application, this might take the form of automated end-to-end tests (Selenium WebDriver) - then, progressively refactor and unit test components and code paths. By the end of the process, you'll end up with a comprehensive regression suite, giving developers the confidence to make changes with impunity - whether that's refactoring to eliminate more technical debt and speed up development, or adding features to fulfill business needs.

This way, you can take a gradual, iterative approach to cleaning up the system, which should boost morale (a little bit of progress made every iteration), and minimises risk (you're not replacing an entire system at once).

I've used this approach to rewrite a Node.js API that was tightly coupled to MongoDB, and migrated it to PostgreSQL.

Absolutely, I might take a month off to mock it up, but actually what I want to do is leverage all the existing google technologies. I could make it look like it would work, but it would need some co-operation for it to actually work.

I think part of the success of facebook is that it has so many tools and utilities built into it. It's not just a place where you share links about stuff you found on the internet and comment.

I'm looking at Google+ right now, and I cannot work out how to message one of my friends. Thats got to be the most fundamental features of a social network.

I had to dig to even find my friends list.
That doesn't help, they can read your DNS requests as they pass through. Unless you do as some others here suggested and use a full VPN.
>> You can always add more homes to include more people.

Can you, though? Any given neighborhood has limited space to build things. At some point, you have to start building high-rises all over to pack more people in. This also has a limit, so beyond that you'd have to start building over parks etc.

Of course, without government-imposed zoning laws, you will also have residential units competing with commercial and industrial ones, too...

Oh, and who will take care of the extra infrastructure that is required for more people?

So it would seem to me that this approach would result in extremely densely packed neighborhoods with poor infrastructure, and undesirable placement of (cheap) residential units next to, say, an industrial park.

It would also be pretty effective at inducing more rich flight from urban areas into the suburbs, which is likely to hurt the cities even more (by reducing their tax base).

I don't think this is all that simple.
I'm also excited about this course like never before. Although, Udacity already has courses on machine learning that cover everything from the basics to reinforcement learning and Tensor Flow, this course is much more hands-on and will probably cover a wider range of topics like fusing data from sensors and algorithms for localization and mapping the environment.

I studied computer science but remained interested in electronics, mechanics and signals and system. One of the projects I did was a GPS guided rover. I did all the electronics, programming and mechanics stuff and wrote basic obstacle avoidance, localization and navigation code myself. I enjoyed every part of it. I wanted to make the rover very sophisticated, which retrospectively was a very high goal for a semester-long course. Anyway, I went ahead and bought two books, Kalman Filtering: Theory and Practice Using MATLAB and Principles of Robot Motion, co-authored by Sebastian Thrun. I didn't get the time to read beyond a few chapters of Thrun's book then but it was very well written and included some great stuff like an introductory chapter on topology. Eight years since and it seems finally I have the motivation to read it cover to cover.

Since the course starts later this year there's time to learn Deep Learning and perhaps Gazebo simulator, which we might end up using for simulating of our own self-driving cars.

Assuming your numbers government spends $15k for every 1 of those 300 people. That number seems pretty high.

The Tampa Bay investigation's violence refers to violence in the hospitals itself and not the general violence in society. For 13.5K per year you might reduce the hospital staff by 10% but that is unlikely to result into chaos that the report seems to suggest.
Speaking idiomatic English is irrelevant in technical or professional discourse however. His point is clearly made, even if it is not the most natural syntax/semantics possible.
Can someone explain this sentence to me?

(In the quote below, he names the AND function "f", which in itself is a bit strange. What's wrong with "and" or ∧?)

f(a, b) produces at most a or b, whichever is greater:
f(a, b) ≤ max(a, b)

As far as I can tell, the result can never be greater than the smaller of a and b. I can't come up with a counterexample. Is there one?
Yes, it is.

But ^ and ∧ are different.
> If it makes them more money, don't they have a duty to their shareholders to use that asset to generate profit?

Unless explicitly laid out in their corporate charter, no. There is no default effective fiduciary duty to do anything related to profitability, be it "maximize" or otherwise.

This is one of the more pernicious myths about the idea of the corporation that needs to be killed.
It has been pointed out before, but I'll mention again. It is impressive how PostreSQL community reacted. There was no immature name calling, no blaming users. They analyze the problem, mention possible solutions, admit known shortcomings and so on. This is a community worth being a part of and engineers worth working with.
I'm not sure what anything you said has to do with their choice of database.
I appreciate in-depth analysis, the numbers, and the actual case studies, and resulting recommendations. This is a very good resource that puts actual numbers to the issue.

In my opinion, this reveals that HTTP/2 Server Push is essentially one huge microoptimization, proper use of which requires even more effort from both the server (and the client):

[1] watch and aggressively respond to network utilization

[2] construct a dependency graph of resources (presumably by actually parsing the HTML on server-side, or beforehand out-of-band and store it some other place)

[3] have the client communicate the state of its cache! [ref-1]

[4] have custom, conditional logic for cookies

Not necessarily. Average =/= median. But with a population as large as the US, they will be pretty close to each other.
I agree, some time ago I wrote down why I liked GUIs and this was the main point.

A relevant part is:

This also means that for every commit, you ‘must’ skim
through each file and stage only what you want to commit.
This serves as a final reminder of your code and has on
multiple occasions led me to moments where I had added
some temp code which wasn’t supposed to be committed.

Do you have the domain name used for the central server? I doubt a whois is very enlightening, but it's another thread to track down.

I completely agree. It's human nature to become defensive when presented with conflict with your current way of thinking, and yet here they didn't do that.

I thought that this article was a very well reasoned and thoughtful response to the Uber article and gives me hope that PostgreSQL will continue to improve.

Find My IPhone should allow the owner of a stolen phone to make it so that the phone cannot be turned off by the power switch on the device itself. For non-4G/non-LTE devices, It should also aggressively look for open access points and attempt to associate with them and phone home to Apple servers with location info. Activating stolen mode should also put the phone into a power conservation mode to keep it alive and phoning home as long as possible.

Edge. Cases.

Such scenarios are rare enough that they could be handled either remotely, or not at all. The ambulance won't get through and its patient will die. Tough luck. But think of the many accidents those automated cars avoided in the first place. It sucks, but it's still worth it.

Also, cars don't have to be fully automated. They can still be remotely controlled, or otherwise warn their company that they should call a tow truck. My favourite example is automated trucks: you'll most likely have a central dispatch per region, with a few operators that manage 50 trucks each. Once a truck has a problem the computer can't handle, it just calls the relevant dispatch, where humans take over.

Also, automated cars don't have to do better than humans in every dimensions. Safety is paramount, but resilience in the face of unusual situations is not. It is okay for the computer to get you to your destination a bit more slowly, or even not at all from time to time. Even public transportation has way less than 99% reliability for my commute to work, and I still take it.
They can be, and they are in certain linear PSUs. Linear PSUs generally make ripply DC with linear power transformer -> rectifier and then use active linear analog circuits to get clean DC power. Has very low efficiency but exceedingly low noise.

For most consumer things, you use a classic switch mode power supply design. You bridge rectify mains directly, and you switch that really fast to get the DC you need, and you filter it a lot.

You're right. Unfortunately, the current culture is "more, more, more", even when it's Comcast, which must be like squeezing blood from a stone at this point (what growth potential is there with an ISP of their size?)

If the board doesn't take action to raise profits, the shareholders will remove uncooperative executives and replace them with those who will. So it might not be de jure in their corporate charter, but that's the reality.
Cities like Seattle are under-built to the point that the vast majority of the land is still single-family zoned, meaning you can only build one home on a plot that may be 2500 sq ft or more. 65% of Seattle's land is still Single-Family. [0] This map will showcase the problem. [1]

There is much to be done to make cities like Seattle more livable and affordable before we come anywhere near the density cap you refer to.

"building codes" is an oversimplification. Some building codes are necessary. But some, like height limits, parking requirements, and setbacks, conspire to make it very difficult to profitably build architecturally interesting buildings.
> Any given neighborhood has limited space to build things.

That's fine. A neighborhood full of high rises that no one wants to pay to knock down to build taller is naturally full. The government hasn't declared it to be full the way we do today.

> Of course, without government-imposed zoning laws, you will also have residential units competing with commercial and industrial ones, too...

Zoning isn't terrible. Density restrictions are terrible. They are explicit exclusion. They are the direct cause of our increasing economic segregation.

> Oh, and who will take care of the extra infrastructure that is required for more people?

Urban infrastructure is cheaper than suburban infrastructure. We're spending more money on infrastructure today than we would if we stopped excluding people.

> It would also be pretty effective at inducing more rich flight from urban areas into the suburbs

This just isn't true. Tons of wealthy people want to live in dense urban neighborhoods. That's why they're so expensive. What we should change is allowing people with different amounts of wealth to live in the same neighborhood. Density restrictions make mixed-income neighborhoods illegal: only the highest bidders get scarce homes, so families are forcibly sorted by income into separate neighborhoods.

If rich people truly don't want to live in mixed-income neighborhoods, they are the ones who should leave. We shouldn't force others out for their benefit. We used to do that. Now we're doing it to even more families. We aren't repeating the mistakes of our forefathers, we're outdoing them.
Four Hack Reactor Students Will Build Your App Pro Bono
Hey YC,

I am completing a software engineering program by the name of Hack Reactor, and I am on a team of four skilled software engineers that have five weeks to build out a project (or functionality of an existing project) as a capstone thesis.

As a long-time lurker of HN, I thought it would be a cool opportunity to offer up our team for the next five weeks to any founders looking to build out a new application or functionality of an existing application.

We are specialists in JS, but are largely stack agnostic.

I'd love to give back to this community and look forward to working on something awesome!

I love trying out all the cool new stuff coming out but most of my actual playtime is spent in multiplayer experiences like Rec Room, QuiVR, and Hover Junkers.

A lot of stuff is free right now which is awesome for consumers. Social games like Rec Room practically have to be free and that team seems to be positioning themselves well to be the go to social experience. It's so strange, where the hell are all the big players?

I think you can still get your VR game on Steam with basically anything these days so if you have the chops I would say it's well worth it to put a prototype out there to see if it sticks. Stuff like https://github.com/thestonefox/SteamVR_Unity_Toolkit makes it really easy to get started. Everyone is starved for content and many of us would pay $5-$10 for a short or bare bones experience if it's done well.
Well, she's technically correct. The "cloud" is just a fancy word for someone else's computer. Be it in California or the middle of nowhere in Utah.

You're correct, it can be changed to `min(a, b)`. A rough proof:

* assume WLOG `a = min(a, b)`

* `a & b` takes the set bits of `a` and produces a subset of them

* the value of an integer is `SUM 2^j` where the j-th bit is set

* removing positive elements from a sum can only make it smaller

* therefore & can only produce a value smaller than `a` (the minimum)
Competing at the top level of any sport (athletic, mental, or otherwise) requires the right training and support almost as much as the right mindset, work ethic, and talent. The training and support requires time and money.

At present, people of different ethnicities have a disproportionate share of wealth, and thus fewer resources that they can spend on training and support. Support begins early: parents help their children find the right activity to undertake and also teach them the mentality to work hard at it in order to compete -- this is almost impossible to accomplish if those parents have to be away most of the time because of financial constraints.

As for gender, we have only recently entered an era where we recognize that girls are equally capable of doing things like math at a top level (the first Fields Medal given to a woman was given to them quite recently). In girls' formative years, parents still have some subconscious expectations of what their children are capable of -- perhaps being reluctant to expose girls to the sciences or other serious undertakings. There are some recent efforts to get girls into these things, but the fact that they are newsworthy proves that it's not the norm yet. The time that there will be equal female representation in these areas will be when an entire generation understands that women and girls are equally capable of getting into them. This will be after everyone who comes from the previous era of society have died.
Not a lot of readers yet.

But it's promising.
While I do not think that you have to win competitions like this, you should probably aim for a placement at least roughly corresponding to your GDP and importance in world politics. I mean Germany is deciding the faith of Europe during difficult times, but places behind small and/or poor countries like North Korea, Taiwan, Singapore, Hong Kong, Vietnam and so on?

I think this should be something that bothers us, we do not accept and take on as an issue. When Germany performed really badly in football at the Euro 2000 and 04 (and lucked through the WC 02), it changed the team, reformed the whole system and has since had an all-German Champions League final, a World Cup win and consecutively reached every semifinal in every WC and Euro. Similarly, England pumped a ton of money into sports to score at its Olympics in London and it sure did.

(Western) Europe likes to discount these achievements by pointing at tiger moms and authoritarian education for Asia and elitist, overly performance centric instead of humanist education for America. While there is probably some truth to that and I do not think we have to change our whole system, I do not buy that Asians are simply geniuses. We should value achievements like this a bit higher and we can and should probably do a bit better even with European genes.

The human cost of unpaid tech debt.
I've run across this situation many times (I'm a "senior" team lead, meaning, I've been working for 25+ years). I've witnessed companies that overcame tech debt, and seen companies fail because of it. There's basically three approaches that people can take.

One is the "big re-write". They start on a new code base, and try to develop it in parallel. It takes a very long time, and the teams have to work on two solutions for some time. It's a big bang approach, and it often fails, or drags on for years.

The second is massive refactoring. It requires intensive testing and best practices. This strategy requires that the teams focus on testing intensely. However, often the testing culture is not there, which is why the code became unmanageable in the first place. It's kind of like starting over. And the new focus and discipline on testing is hard for teams to do without strong leadership, training, or new talent.

The last, and most effective in my opinion, is to go with a service-based, incremental approach. If the code base is not already using services, APIs must be built. Frontend/apps must be de-coupled from the legacy components. A clear domain model has to be agreed upon, and then parts of the legacy codebase are put behind APIs, and de-coupled from the rest. Over time, sections are refactored independently, and the APIs can hide legacy away. Maybe the legacy parts are refactored and replaced, or they stay around for a while. But the key is, that this approach allows multiple people or teams to work in parallel and focus on their areas. This is domain-driven design in action, and it works. New features can actually be developed sooner, even though the legacy is not replaced yet.

In the end, overcoming tech debt is about people. And on larger code bases, it's more of an organizational problem than a code problem. Developers need to be able to move forward without having to navigate too much code or too many different people.
it still values Facebook less than Netflix, which is not for the rich. I'd easily pay $10/month.

But I highly doubt Facebook has ever seriously considered it. It would alter their brand as a data mine to businesses way too much. I highly recommend dns level ad restriction plus heavy stylesheet modification. Just trash the mobile app or route it through an tracking blocking dns proxy. Obviously don't like businesses and never click on ads.
