My 9 month old had his brain (and other organs) checked whilst in the womb during one of our ultra sound checks. BTW, it might be a country specific thing. I'm in the UK.

Did your twins get ultra sound checks?

Making “never break the build” scale
In Canada, a significant amount of medical procedures (possibly all of them?) have pre-set prices. A visit to a doctor's office costs X. A hospital visit costs X. There's no 'how much might you charge for this procedure tomorrow?'

Of course, Canadians don't pay out of pocket for the vast majority of insurance things, but it even extends to other non-covered services like RMTs, dentistry, etc. Private insurance may not cover some specific things (like white fillings on molar teeth), but you never have to wonder what the prices are or how much you'll end up paying if you say yes.
The tiger [it's a leopard] and stingray [some other ray?] are wrong, but the system is 100% certain they're right; seems quite a big error considering the apparent accuracy of the other labels.

Isn't it contextual - flat-coated retriever, well-done, but how good is it at picking one out of a pile of images of black animals, panthers, house cats?
I thought that was obvious. OP was making a point about things running without cache at the cost of increased load... I'm sure Google Search couldn't reliably achieve that right now, but we were not talking about Google Search.
I wonder how well rsync would have fared here.
This is how you get slums.
But (3) is not the case here, presumably - I'd wager that most of the people selling, e.g., cocaine on Silk Road 2.X aren't harvesting the coca leaves themselves.

I'm also not sure that (4) will out-compete the other kinds. That's assuming that consumers place a higher value on fair-trade and conflict-free than they do on getting a cheaper product. What if fair-trade-conflict-free costs 5x what the unverified stuff does?
I'm assuming this is your interpretation of their position, and not a statement of belief. Because as always, the libertarian position is wildly at odds with reality and history, and grossly over-estimates the impacts of the factors it can control, while grossly underestimating the impact of the problematic ones (to take an example from the above: it presumes that the cost of murder-for-hire is high in the places drugs are made. It has no answer beyond falling back of ideologically not caring if it turns out to be a sound business strategy).
A big problem to solve is that SMS is notoriously bad at delivery. You may have SMS's dropped for weird reasons, and delivery reports aren't exactly reliable.
Awesome app. I was thinking about something like this recently for a niche.

I was going to ask how you direct the SMS to the app, but taking a quick look at the src, it seems the app reads the sms inbox, looking for the specific phone number?

I guess this means that:

- the user sees alerts for the incoming sms?

- the user needs to delete (does the app/could the app do that?)

Great stuff, really interesting. Thanks for sharing it.
Wouldn't they be more interested in going after the distributors? I guess if they nabbed enough buyers, they could kill the market, but it's an awful big market.
I think one factor that leads to bloated, ruined software was missed... I don't know how common it is overall, but I have personally seen it ruin several very good products.

And that is the simple fact that employers want their employees to remain busy. If a piece of software reaches a point of exceptional quality - the developers working on it still have to fill 40 (likely more) hours a week to appease bosses. And so they do the only thing available - they ruin the product. This is one of the reasons that I think software engineers should, in certain cases, work on retainer. Domain knowledge of a specific product is very valuable, and companies routinely ignore this. They will shuffle an engineer off to some newer project and leave a more junior person to handle maintenance of the original project - and that junior person will have to fill their time somehow. This serves no one except for the shortsighted manager who determines their self worth by how many and how much they control their employees.
Nobody is talking about shorcuts.

You learn by starting with the tens place and moving on to the ones place. LEFT to RIGHT. NOT right to left.

27+38

30 + 20 = 50

7+8 = 5+8+2 = 5+10 = 15

50 + 15 = 65

This is a lightning fast process that you do on paper to understand, and in your head in practice. Carrying, as I've said 3 times now is inefficient, slow, and harms the future possibility of doing well in upper level math.

BTW, I'm no stranger to the alternative media. Hell, I still watch the Infowars feed. (I would also say that the english side of common core is appalling.) But you have to recognize that the stuff is 99% bullshit, just as with the case with FOX and CNN. (Note that math can NOT be memorized, you're dealing with infinity.) These sites pander to a specific audience just like everyone else. Hateful/scared people love hateful/scared sites. Its a shame everyone has to spin everything into something bigger than it actually is.

Just the facts. This kind of math is faster, easier to learn, and easier to do. It's results (already proven) create a higher confidence in math and a better ability to perform at the higher levels. This stuff isn't new in any way. It's the same as using an abacus. (You know, those things they used in old one room schoolhouses where you slide the ones and ten places?) And tell me, how well do you think modern Americans compare to children in the 19th century with math? You sell yourself as someone who might know about a certain book by Charlotte Iserbyt, so I assume you know where I'm going with this.

Check out the Khan Academy site listed in the OP and do a little for yourself. Learn it in order to understand it.
So this seems stupid.

SMS is the most expensive data service on the planet. It costs more per byte to send SMS then it does to send data to Jupiter (factoring in the space ship you had to launch there to receive it).

WhatsApp's entire business model is based on the fact that SMS is just stupidly expensive.
The answer OP poised was that Wikipedia and Open Source require text based interactions with others in the community - beyond the actual exercise of writing wikipedia pages and writing code. Thats the difference here, not that women don't like reading or writing.
I think big corporates are a perfect example. Have you ever poured your heart and soul into a project only to have it canned for political reasons? Ever worked in a job that could be automated or done by half as many people but doing so would reduce a managers/directors/departments power? Ever wanted to switch to working on important projects where you can make a difference only to have your manager refuse your transfer because it would make his/her job harder?

This sort of stuff is common in big corporates and a natural response is to do the bare minimum.
Microsoft is poison to carriers because Microsoft owns Skype which takes away revenue and profits that carriers would otherwise gain. Plus Microsoft treats carriers the same way it treats computer manufacturers - it dictates. Carriers have other phones to offer so dictation does not work.
A very interesting question!

For me, some of the way I think things through seems very physical to me. The sort of thing you do when you pick up lunch table objects and say, "Ok, this salt shaker is the web server, this fork is the firewall, and..." Except I'm more likely to do it with just gestures, or just thinking about placing things in an imaginary space.

I wonder how much of that is really enlisting the cerebellum versus it being an output-only thing. Perhaps nominally output-only devices do more. As in rubber-duck debugging or Flannery O'Connor's line, "I write because I don't know what I think until I read what I say."
You're right that Chrome OS doesn't store any of that at the moment. But this is the sort of integration that would be fairly easy for Google to add. Chrome already has some minimal integration with Google web services, especially on Android where Chrome will automatically log in to Google for you. How much bigger a step would it be to fetch your Google contacts while they're at it?
About rsync: if you just use -a, it does not copy hard links correctly:

-a, --archive
[...] Note that -a does not preserve hardlinks, because
finding multiply-linked files is expensive. You must
separately specify -H.

If you do specify -H, rsync does keep track of hard links, but presumably at the cost of keeping a data structure similar to cp:

-H, --hard-links
This tells rsync to look for hard-linked files in the source and
link together the corresponding files on the destination. Without
this option, hard-linked files in the source are treated as though
they were separate files. [...]

Of course, rsync could be more efficient at keeping track of the hard links than cp, but there's no reason to believe a priori that it would be.
I didn't know that, is that universal or only for math? It definitely makes sense for math as you can get close and easily guess. So you can have no idea what you're doing and still get a 70% or so.
Profiteers. The other day someone asked about finding a job just like that.

No kitchen, toilet, running water or insulation? It's about as livable as a kid's tree house. Plus, it probably violates about half of the building code. This is simply a publicity stunt.
This comes down to the myth of "us" vs. "them".

I guess it was my mother that taught me to perform substitutions on the fly when reading or listening...

Here are the substitutions I used on the Senator's speech:

"American worker" --> "worker"
"guest worker" --> "worker"
"single mom" --> "foreign single mom"

OK, that last one was just for my own amusement! :)

Once those substitutions (and all conceptually similar substitutions) are done, the speech doesn't make sense.

Since I always perform the substitutions, since I have done so since I was a child... nobody's anti-immigrant spew has ever made sense to me!

For what it is worth, I'm white and male. I guess my mother was a bit of an oddball, though.

I have found it very difficult to interact with people that see the world as 'us' vs. 'them'. Any advice?

[NB I started skimming the Senator's speech halfway through. Not a lot of new material in there.]

Skip to the end if you don't have time to read the whole article. It's not ancient history.
Rsync has similar issues when you are copying hard links. It has to keep a table of all the inodes/filename pairs it sees so it can detect hard links and relink them on the destination. This can be big if you have a ton of hard links (say in a backup situation).

Rsync at least acts reasonably idempotent, so you can just run it again if it gets interrupted, which is usually why I use it for large copies.

I don't remember off the top of my head if tar handles hard links—it may be inappropriate for this usage.
Right -- in five years. Just like nobody will ding you for telling them what happens to Romeo and Juliet, or that thing about Darth Vader, because by now it's assumed that anyone who cares to experience that thing un-spoiled has already finished.

The last episodes of Breaking Bad have only been on Netflix for about 6 months. It's completely plausible that people who decided to start watching after the series reached its critically-acclaimed ending might still be a couple seasons shy of the ending. Hold your spoilers for another 3-6 months to be safe.
Stand out would be true.

Unfortunately, what happens is that the Spanish are the whites, and the Indians are the native cultures. Then you end up with Mestizo, which somewhat maps to the word Nigger here in the US. And unlike our incursion with slaves in the US, the Hacienda system lasted for almost a half a millennium.

Mestizo means mixed. And that's what they are treated as. Not good enough to be native, and not 'pure blood'.
Aren't Android apps run in a virtual machine (because of the Java roots) anyway?

I've used ZFS (FreeNAS) for quite a few years and find it pretty flawless. Trust it's not too dumb a question but what advantage is there to running ZFS on Linux when you can run it on variants of Solaris or BSD just fine?
When two parties mutually agree on some deal they both feel satisfied and have incentives to make each other happy. When the government decides what is the "interest" of one party and steps in to "protect that interest", very likely it will end up pissing off one party which eventually loses interest in any kind of innovation.

US has achieved the rare distinction of screwing up both the parties in case of healthcare.

Indian government in reality has even more laws and nonsense but it is too incompetent to implement any of those laws. This mostly leaves the things in a Laissez-faire situation. Like it happens in any Laissez-faire situation the third parties see too many problems but the people who are actually affected are more than happy because they are a better judge of their situation.

In my village in India, we have only 1 doctor. This doctor is a homeopathic doctor who even today charges Rs 10 ( $0.16) per visit. He spends less than 5 minutes per patient and his treatment is allopathic. He moved from a distant city to this village purely because homeopathic doctor giving allopathic medicine is illegal.

Over last 30 odd years not only he has got rich but he is the most powerful person in the village. He is very good at his job, has saved countless lives, delivered babies, removed aching teeth and written countless death certificates. Yes, there have been cases of wrong diagnosis and side-effects too but overall he has lead to net positive benefit to the society in my village and hence is revered.

Many proper doctors tried to setup their shop in my village and have failed purely because this doctor turned out to be better than them.

In India, Indian Medical Council controls the total number of doctors in the country but for a bribe of around $2M you can easily get a license to start a medical school. Medical Schools make insane amount of money and thousands of poor people enter the hospital everyday where you can get away making mistakes because the choice before these poor people is "either get this treatment or die in your home".
Darn, thanks! I've been using rsync for incremental backups (themselves hard-link-based) for years, but neglecting to do this. That is to say, snapshot N+1 shares structure with backup N to save space (via hard links) via --link-dest. But files may be replicated because -H (missing) is orthogonal of --link-dest.
It's still not racism. Prejudice? Yes. But unless you're believing they're inferior because of their race then you're not being racist. I guess in the layman's version of racism you're being racist (regarding examples 2 and 3), but per the actual definition you're not.
It seems pretty implausible honestly. Most people order their stuff from people in the same country as them as otherwise it risks being caught at the boarder. This means the product is probably still crossing boarders in the same way it always has. And that generally means cartel /organized crime played a role.

It seems far harder to believe that both fair trade sources and conflict free delivery systems sprung up than the idea that anonymous dealer is telling fibs.
On debian-based systems, /etc/cron.d/mdadm will already do this on the first Sunday of the month.

One thing most homeless people need in order to find a home is income. Being homeless carries a huge stigma with it that can make it difficult to find a job, so low-income (or no-income) housing is indeed immensely important. However, one big problem with such housing is that it often isn't that close to jobs. People who can't afford a home often can't afford a car either, and Austin's (for example) public transit is a hot steaming pile of garbage. Rich people in the suburbs typically don't want low-income housing next to their homes or shopping malls so, indeed, zoning is an issue. Concentrating low-income housing in one area creates a lot of problems.

Another major problem is that there is a large correlation between being homeless and mental issues. In Canada, you can go on welfare and get housing if you need it, but you have to jump through hoops and interact with government employees to do so. Some people just aren't able or willing to do that. Of course, the climate is rather deadly up here for large portions of the year. There are shelters that the homeless can go to, but there are always those who seem to prefer sneaking into abandoned buildings or sleeping on transit vehicles. Persuading these people to get off the streets takes a lot more resources than people expect, so those resources just aren't there a lot of the time.

Perhaps small, spartan, stand-alone shelters that aren't in large blocks of low income housing and aren't formally assigned would attract those unwilling to seek other forms of shelter.
If you enjoy thinking about this, you might like the book "Blindsight," a sci-fi novel written by a biologist. The main character had a hemispherectomy as a child, and all the major characters are far from neurotypical. The book is creepy as hell, but incredibly interesting.
That's only in some countries (eg: US). In other countries, SMS is way cheaper for example, for the cost of a dollar or so, you can get a plan that allows you "unlimited messaging" or some obscene number of messages per day (more than you can reasonably type). For example, I know this was the case in India as recently as a couple of years ago -- and then they capped it to try and stop telemarketing spam.

So there are definitely places where SMS is cheaper than data access. In the US it's inverted purely due to the business model choice of the carriers.
Interesting.

In Windows-land, the default copy is pretty anemic, so probably most people avoid it for serious work.

I'd probably use robocopy from the command line. And if I was being lazy, I'd use the Teracopy GUI.

I think my limit for a single copy command has been around 4TB with robocopy--and that was a bunch of large media files, instead of smaller more numerous files. Maybe there's a limit I haven't hit.
Inner ear problems sound like a far more likely issue. But, I would just talk to your pediatrician vs. soliciting random advice on the web.
Wikipedia is very far from done in updating articles about psychology[1] or genetics.[2] Most articles on Wikipedia on most topics still need a great deal of work. Even by Wikipedia's own meager standards, few articles have reached "good article" or "featured article" levels of quality.

My cellphone plan gives me unlimited SMS but only 2 gbs of data. If unlimited really means unlimited, then my data comes to me for free (assuming I was going to keep my sms package regardless, which I am).
Sounds like laziness to me, which is of course rampant among teachers.

It does amaze me that googling "common core math" brings up the things it does. Even in a world where we have access to all information, everyone seems to be trying to bullshit everything. I find it very difficult to find the facts on most things.

But when I saw that Khan Academies methods were starting to mirror "The Great Courses" "Secrets of Mental Math"[1] and that it was a part of the common core, I was impressed. Once I started learning things this way, I was better able to handle all math. I used to hate it, dread it. But this kind of thing makes it easy and fun. I'm glad kids are being exposed to it.

I'm not sure how to trigger self reflection in others, I grew up doing it and thought it was something everyone did until I met lots and lots of people who never asked themselves "Why did I respond that way?" or "Where did that come from?".

This is called "metacognition" in educator circles, and it can make a big difference in how people react to different situations. The skill to evaluate and monitor your own thinking is something that many people never learn. See e.g. http://www.etc.edu.cn/eet/Articles/metacognition/start.htm
Typically when copying from one machine to another, I've had the best results by far with tar | tar, but I'm not sure how well that would fare with tons of hard links like this. I think it's possible, but the default behavior would just gobble up umpteen copies of the same file.
Effectively they issue a bond bundled with a bunch of options that may be exercised in exchange for giving up ownership of the bond, "converting" it to equity.

This isn't necessarily driven by a view on the equity valuation. It's more often driven by high realized volatility in the equity, which increases the value of the equity optionality. Correspondingly this decreases the value of the fixed income aspect of the bond, which from the issuer's (Twitter) perspective means they pay less in interest.

Note that "Twitter expects to enter into privately negotiated convertible note hedge transactions". This means that they will buy call spreads to help manage the EPS impact of increasing the fully-diluted share count. Realized volatility and the pricing across strikes of the option chain will be affected.
If this was the Chrome dev tools I'd be very very happy.

This is a known potential problem. The solution is long term reputation and also a relatively high initial bond to the site to make an account.

In terms of circles of buyers and sellers they can use all the algorithms that people like ebay have been perfecting for years. Not a new problem.

Obviously not water tight, but it seems to be working well enough for these sites to function.

there is also pocl (http://portablecl.org/), which aims to one day target GPUs (although currently it does not).

the issue with free OpenCL implementations on the GPU is that the runtime will be closely coupled with the device driver, so short of open source drivers, there most likely wont be an OpenCL runtime that uses proprietary drivers.

that said, i believe both open source nvidia and radeon drivers support some level of OpenCL, although it's been a while since i've checked them..

nvidia will do what nvidia will do, they obviously have quite a lot of upstream swimming to do before they realise that CUDA is not the best approach to take.
