We only need to ask teachers that have worked with students in these underperforming schools and you'll see a pattern emerge - students that are not having their needs at home met are oftentimes not able to come prepared to learn at school. Furthermore, children in impoverished families tend to have to move frequently (parents have unstable incomes and unstable rent) and this disrupts social bonds as well as continuous learning.

Trying to spend more money on education when children don't have basic needs like clean running water and food at home is complete nonsense and our expensive, ineffective programs are reflective of this double standard and a form of siloized, segregated government policies and departments that cannot tackle widespread, complex problems. This isn't to say that private sector would do any better though.
I bike to/from work (on a regular bicycle) over a few hills. I enjoy the exercise in general, but I would still like a electric bike for the summer; a sunny Texas day with 98+ Fahrenheit weather is rough.

Could be both, too.

I'd also be interested in seeing the correlation between the political power that poor and/or non-white communities have in the area, and the likelihood that they get stuck with such things in their neighborhoods. Anecdotally I've heard stories from the days of widespread highway construction, when both rich, white and poor, black neighborhoods were supposed to get highways built right through their neighborhoods, but only the former managed to lobby successfully against them.
Coal is one of the nastiest, polluting, disgusting ways to produce electricity. Often, it's even the case that burning coal leaves a radioactive slag (because of materials that came with the coal while mining) so that a coal powerplant has radioactive waste too!

>A 2007 study by University of Michigan researchers seemed to back Gesell up, showing those living within 2 miles of the Field Laboratory were 60 percent more likely to be stricken with cancers of the thyroid, upper digestive tract, bladder, blood and lymph tissue than those who lived more than 5 miles away.

What's the likelihood that a randomly selected geographic point in the U.S. will yield that same contrast of 60%?
I agree that list management has been an afterthought for Twitter for quite some time.

Have you attempted contacting @bbstripes, the maintainer of twitlistmanager? This seems like two great additions to an existing tool you already use and the developer even accepts paypal for donations to the tool.

I think in some juridictions you might be viewed as having provoked the theft. And provoking the theft seems to annihilate the prosecution at least when it is done by police (eg leaving laptop on seat in car under surveillance to arrest thieves), as has been the case in the past in (I think) belgium.
100m^2 doesn't seem like so much to me at all, certainly not sobering.

This would mean one acre of land would sustain about 40 people (or 100 per hectare).

Taking wikipedia's number of 13,958,000 km^2 of arable land in the world, this would mean a maximum world population of 137,963,876,580, which is about 20x the current world population.

Of course, this assumes equal quality of land to the land in your rough calculations, and I am guessing your number is assuming far more intensive cultivation than is typical (typical numbers I've seen are 1-2 acres / person).
Indeed, I was noticing after my comment that the automatic access of globals is a different behavior than the access to other variables outside the lambda's scope, but not globals.

Thanks for the example.
How LSD went from research to religion
Common Core has attracted some rather far out criticism. I have not been able to decide whether this is amusing or appalling.

It "will promote double-mindedness in state education and attract every one of your children to become as homosexual as they possibly can", according to Florida State Rep. Charles Van Zant (R) [1].

Similar criticism from the American Family Association [2]. If it is not stopped, the only way for Christians to survive will be to form a parallel society with its own jobs and economy [3].

According to Glenn Beck, "that's why I think common core is here, because it will train us to be a serf state, it will train us and it will keep us in order to answer to the Chinese or whoever it is". (He thinks we'll be ruled by an American technocrat under the control of China, with China employing Muslims as enforcers to keep us in line). Video of Beck covering this here [4]. Summary here [5].

According to Dr. Karen Effrem, president of Education Liberty Watch, creates "a womb-to-tomb dossier on kids and families" that includes between 300 and 400 different data points, such as parents’ voting status, religious affiliation, medical data, newborn screening and genetic data [6].

You're presuming man pages are primarily meant to serve as a reference. But I rarely need man-pages as a reference†.

Most of the time, if I'm looking up a man-page for something, it's because I've just installed a new package that sounded like it would solve a problem and then did a dpkg-query(1) to find out what binaries came with it—or used apropos(1) to find a relevant binary already installed—and now I want to know what the uses of a given binary are and whether those uses include solving my particular problem.

† Well, except for the utilities with absolutely horrible command-line UX-design, like tar(1) or ps(1) or rsync(1), where I just memorize the options I need for my usual case, and then have to look in the man page to do anything novel.
That's a fair interpretation.

In the USA a number of states are de jure community property states. In those states, assets acquired in marriage, and appreciation in value of assets owned before marriage are both considered to belong equally to both spouses.

Many other states are de facto community property states. There is often some sort of "equitable" division of assets in a divorce. In practical terms this often appears quite similar to the de jure states.

One of my favorite quips was from Tom Arnold, during his second divorce. He said something like "she wants half of half of Roseanne's money".

How are you going to discuss all that in a substantive manner? All anyone can do in the limited time frame of a HN discussion is draw parallels to previous job experiences or previous user experiences.

My own experiences are more aligned with the sentiment expressed in the "dismissal" comment.

Why does the DMV even exist? If we didn't have driving tests, would it really matter at all? Do we need all this paperwork to own a car?

What if we didn't have any of it at all? Does anyone think that some 16 year old who barely passes the driving test is any better of a driver than that same 16 year old who didn't have to take the test?

The DMV just shouldn't exist. We could abolish it tomorrow, fire all the employees, and spend the money on useful things. Literally nothing would happen, nothing would change.
Few areas in the US have cyclists. Most areas are only connected by one highway system or another, and almost no highway system has any bicycle lanes. There are a few exceptions, like the Interstate 90 floating bridge over Lake Washington, which has a bicycle and pedestrian lane. While some cities have a reputation for bicycle friendliness, like Portland and Seattle on the West Coast, many merely give lip service to bicycle lanes. And that's only within cities, often the only way to travel between cities is hoping you can find a bus with a bicycle rack. This is sometimes impossible in rural areas.

Yet there is a trend for bicycle renting, with automated bicycle rental stands in many areas of several large cities. In a way, it expresses the duality of American culture as well as any other measure.
Naively, the poorest people are the least able to uproot and move somewhere else, so if you put a NIMBY like a coal power plant near them, everyone who can afford to leave will move away, leaving only the poorest.

Furthermore, the presence of the power plant will drive property values down, placing it higher on the afforability list for people that are poor and in the market for property.

Give some time for these two factors to play out, and you'll only have poor people living next to a power plant even if it didn't always start off that way.
There is now a new definition for E^2 (one minus the ratio of the R^2 of the model and the "true" model) which doesn't solve the most obvious issue: getting negative values for a measure called "something squared". The values of E^2 in the first example are now -0.13 for the linear model and -0.30 for the quadratic model. In the second example, they are 0.24 and 0.10 respectively.

The graphical representation is a bit misleading. Leaving aside the fact that in the first example MSE_T is between MSE_M and MSE_C, this drawing make E^2 and R^2 seem more complementary than they really are. E^2 is the length of the blue bar as a fraction of the total length (blue+orange). R^2, however, is the length of the orange bar as a fraction of the distance from the end of the bar to the origin (not shown in the chart).

Edit: there is a new addition to the post, re-expressing E^2 in terms of a mean/variance decomposition. It should be kept in mind that the derivation presented is only asymptotically correct. In a small sample, the cross term does not vanish and the variance of the observations around the "true" value is not exactly sigma^2. In the second example, E^2 calculated using this new definition is quite similar (0.2373 and 0.0991 for the linear and quadratic models, compared to the previous values of 0.2382 and 0.0994). In the first example, however, the values we get from the new definition are far from the previous values: 0.0646 vs -0.129 for the linear model, 0.1528 vs -0.297 for the quadratic model.

Edit2: changed "approximation" to "new definition", "good" to "similar" and "exact" to "previous" in the previous paragraph. I'm not sure if he was suggesting to use this formula to calculate E^2 instead of the previous one. Anyway, it doesn't matter because this is not something that can be calculated at all unless the "true model" is known.

Are chat bots still exciting?
It was a hype a while ago and I curious as to if this is something that people are putting their effort into.

The far off future looks like people would not necessarily want to learn interfaces to consume several services, but verbal communication might replace the visual interfaces that are out there.

Using visual interfaces is probably much faster to use than chatting with a bot to get things done, but from what I have seen most people don't use the command line but like using visual interfaces although the former lets you accomplish things faster than a visual interface.
uh... yes, yes it is. see for example http://mathworld.wolfram.com/HyperspherePointPicking.html
Really appreciate this effort. My mathematical background is somewhat lacking and I'd love to pursue ML/Data science where I'm led to believe this is a prerequisite.

what you say is true, but what I said is also truly what I wanted to say, so to clarify:

NYC has widespread ignoring of many traffic laws, and that does not bother me. I am talking about, in the context of widespread violations, what does bother me: the electric bikes. You could accept that there is some validity in what I say without agreeing with me.

Given the choice, I would not be in favor of pedestrians and bikers being forced to follow all traffic laws. However, I would be in favor of electric bikes being forced to follow all traffic laws, especially the one that bans them! :)
Looks like there is something wrong with numbers. Article says 1 square meter will be enough to produce 1MW of energy. But, 1MW of energy will be surely enough to desalinate water for covering 1 sq. m., isn't it?

So, place it at sea-side and get "infinite" amount of energy.

But, more probable, author of the article confused 1MW and 1mW.

So 'single payer government schools' work fine in areas where the adults are themselves educated. They work poorly in areas where the adults are not well educated. No variable you can change will make a dramatic impact.

If the parents aren't educated, they can't tell whether the school is good or bad. In that case, they are going to be conned by charlatans, it's just a question of government charlatans or private charlatans.

If the parents are educated, they won't send their kids to a crappy school, and will either use money saved by living in a worse school district to help pay for private school, or will move. Either way, educated parents who care will not send their kids to garbage schools.

The net of all that is that dumber, less educated people will end up with dumber, less educated children because they don't know how to get their children a good education, or even how to tell the difference between good and bad schools. How you pay the bill or how you organize it will not matter, and studies have shown this over and over.
Hmm.

"Although, the passport is currently exclusive to government heads and diplomats, it is here to stay, even though it will take a while before it circulates among non-dignitaries."

Practically, a main difficulty in ML/Data science, is getting the data. Applying algorithms is largely limited to applying implementations of algorithms.

So, yes, it helps to be familiar with this level of stuff. But don't let it stop you tinkering with what you have access to.
You can devops dedicated hardware. It's a little bit different but not that much. Heck there are boot2docker and such that let you just run docker on bare metal.
$1500 pays perhaps one day of salary for your team of 3. What kind of business has problems affording that?
Yup, as described in TAOCP vol 2 as well.
Where I live (Netherlands) they are mainly used by seniors (60+) or people covering long distances. Top speed is limited to 25KM/h, and that is more than enough to get quickly to any place on your range distance.

They are also useful in cities (e.g. Madrid) where hills maybe problematic for normal bikes.
*I will preface this with the statement that I came into tech from running a creative agency - so take this for whatever its worth.

I think that image is just as important as tech, and those that can put the two together will have a much easier time finding users/customers, and partners.

The cost to have your brand built-out, by a creative agency actually worth paying is in the $15,000-$25,000 range. The math behind that is basically: good agencies work for about $200 per hour (per person) and typically a job like a brand buildout will require 3 people, for about a week. That is 120 hours of work @ $200 per hour, or about $25k. I can tell from experience that you can find deals - sometimes; but I would go into with my eyes wide open, and look into groups that work at that level/rate.

Edit: I did not answer your actual question. The answer is, as soon as you can put together the money to do it.
You say that as if there aren't countless pitfalls that can stop the process, e.g. phone not rooted, installing the tools to do it can be complicated, differences across operating systems, USB permission issues with the android tooling, tooling just not working for whatever reason, phone not behaving the way its supposed to once you are in the bootloader, recovery image doesn't install, the ROM download is bad, etc etc etc

These are not random examples - they ALL happened with the phone I am now typing on.

Its also not something a business could be built on top of, which is the original topic of this thread. Users expect single click installs.
Cars are starting to report collisions automatically so soon it will be very difficult to escape unnoticed, especially when they start reporting on other vehicles around them. At that point collisions, speeding, reckless driving etc accountability will be as automatic as red light cameras and people will drive responsibly all the time because how they drive will always be under so much scrutiny.

Porting Day of the Tentacle to Linux
Honestly, I found this post really weak.

'Pokemon Go does (or not) X, Y, Z, it's growing real quick, think about what you are doing!'. There are thousands, if not millions, of apps that do the same things but they end up nowhere and have total of 3 downloads (one of them is the developers mother).

It's like a list of '10 personality traits of successful CEOs', ignoring millions of people sharing the same traits and stuck at a cubicle and a dead-end job (or collecting unemployment benefits).

Also, it is missing one of the key points: 'Pokemon Go is using an extremely recognizable world wide brand'. We can't pretend that the 'Pokemon' bit of 'Pokmenon go' doesn't matter.
I'm open to hearing about ways to make HN more interesting, but it's hard to have this discussion on the terms that you're presenting. For one thing, people disagree strongly about what's interesting. For another, this perception tends to be skewed by nostalgia: most of us think that HN is worse than it was when we first got into it, but that's because we mostly think that about everything. (Things have always been getting worse, as some wit once said.) There are other biases too: if HN doesn't interest you (i.e. any of us) for a few days in a row, you're likely to think that it's going to seed, but in fact regular fluctuation is bound to yield such stretches from time to time.

If you'd care to find an example or two of a front page from when you think HN was better, that expresses what was better about it, I'd be happy to take a look. You can do that either using the Internet Archive, or by using HN's front page archive like this: https://news.ycombinator.com/front?day=2016-07-23, for any day since 2014-11-11.

For fun and a small bias check, if you do look at frontpage history, keep track of the number of days you looked at before finding suitable examples. e.g. if you come up with two good examples, it would be interesting to know if they were the first two you looked at, vs. 2/10 or whatever.

Btw, the above offer goes to any HN reader who wants to spend time finding examples of how HN was better in the past. Just make sure to give us specific links. Otherwise it's too hard to say anything meaningful.
And, for myself, I couldn't disagree more. Man pages are very well done, since they are more often used for reference than they are for discovery.
