Remember things like this when people talk about biological differences between men and women's brains. Studies sometimes find tiny differences, and then some people claim that's why 19 out of 20 board members are men. It's not bias, it's science!

But if people can live missing massive chunks of their brain, is it really believable that tiny differences can cause such massive societal outcomes?
Incorrect. Please read page 2 carefully.

I get the point about getting rid of cons. You don't need the actual cons data structure; just the accessor abstraction. In TXR Lisp, I define car and cdr for objects other than conses. They are defined in a way that obeys "nil correctness".

$ txr -p '(list (car "ab") (cdr "ab") (cdr "a"))'
(#\a "b" nil)

Note that the cdr/rest of a one character string isn't the empty string, but nil.

So, with a repeating lazy list and a string, we can do the Vigenère cipher in one line:

$ txr -p '[mapcar (ret `@1@2`) "abcd" "1234"]'
("a1" "b2" "c3" "d4")

The mapcar function was modified only very slightly to make this happen correctly for all inputs: its inputs have to be normalized so they are "nil correct": empty vectors and strings have to be mapped to nil. That case does not occur here.

Watch what happens with mappend:

$ txr -p '[mappend (ret `@1@2`) "abcd" "1234"]'
"a1b2c3d4"

Now that required a bit of more of a hack inside mappend: mappend looks at the type of the leftmost list operand and notices that it is a string. Therefore it accumulates a string.

Wait, mapcar has that hack too!

$ txr -p '[mapcar + "abcd" #(0 1 2 3)]'
"aceg"

It didn't kick in in the first example because the function being mapped did not return characters. It returned strings. Strings are not characters and so they cannot be accumulated to make a string. (But of course they can be appended to make a string, which happened in mappend).
Nice! Thanks for sharing man!

tl;dr If you change the way you use data structures a little bit you can come up with parallel algorithms to work on them.

I would say that the average billing clerk in the US and the average nurse in the US and even the person who runs the mechanical systems and drive the emergency vehicles as well as any supplies (if they are sourced locally) are much much much cheaper in India than in the US.

Separately in the US I know of Indian doctors who could practice in India but fail to do so. And they have even pointed out how much "help" they could have (they actually called them "servants") if they lived over in India. Labor is much cheaper in India. This may not account for all of the price differential but running a Hospital in the US is almost certainly way more expensive than in India.

Three Marks Of Real Data Science?
Reminds me of Bob Sutton, a Stanford prof and author who writes[1]:

"This tendency to look for individual goats – and heroes – isn’t just a problem that permeates the world of sports. It is reflected in many misguided ideologies and management practices, which focus excessive energy on hiring stars and weeding-out mediocre and poor performers, and insufficient energy on building a great system that enables most competent people to succeed.

I agree – and can show you evidence – that there are huge differences in individual skill and ability in every occupation. BUT we’ve also got a lot of evidence that ordinary people can perform at top levels in a well-designed system, and even a superstar is doomed to fail in a bad system."

Sutton, you know, researches these kinds of things rather than holding a blind belief that once you hire A players, your job is done.

> These individuals probably also exhibit diminished cognitive function as well.

I wonder how much of that is "the cerebellum is also involved in cognition" and how much of that is "with the rest of the brain picking up the additional load, there's less "processing power" available for other things".
From the talks I've seen Gundry usually tends to qualify comments about OverloadedRecordFields by saying it's not traditional row polymorphism ( i.e. Record { name :: String | r }) ). It doesn't allow row extension or row restriction as first-class constructs in the type system. Although we can build these things as secondary features on top of the language as many libraries currently do though.
Severe brain injuries are all too common in modern times and were probably more common in prehistoric times. X-rays of (mostly) men with foreign objects through their brain are all too common. I suppose being flexible about which part of the brain does what would make the difference between a survivable and recoverable injury, and a debilitating injury, probably leading to death.

Edit: Steven Pinker, in "The Better Angels of our Nature: Why Violence Has Declined", makes it out to be 15% average death by violence, so, pretty common. Explaining his graphs, he says, “The topmost cluster shows the rate of violent death for skeletons dug out of archaeological sites.” “The death rates range from 0 to 60 percent, with an average of 15 percent.”
Well autopsies are rare so it's an unknown number of survivors.
Doing a 360x640 will indeed create a rather awkward situation where iPhone 6 plus have less usable screen space than the iPhone 6 (which is 375x667). Though, my guess is that they want to keep the physical height of elements to be roughly the same across all iPhone family.

This way, all existing buttons that were designed with 44px tapable height in mind or any existing text could have more details in it while not appear larger or smaller than any other iPhones and will have more space to display content. I believe non-mini iPad is the only product in the iOS family that recommended 44px is physically larger than the rest.
Working RAID 5 and 6, RAID "7" (Z3[1], triple parity, where Z/5 is single, and Z2/6 is dual), tiered RAID setups (such as JBOD'ed RAID-Z3s), zvols (as in, but not limited to, swap partitions in ZFS), more nuanced multi-controller and failover/spare setups, write-only journals (ZIL), second tier caching (L2ARC), LZ4 transparent compression, better designed snapshot and snapshot cloning support, more mature CLI tools, support on other OS's (with shared code bases for bonus points), configurable checksum algos, and a few other things that I'm forgetting at the moment.

Three 29-drive RAID-Z3s with 3 hot spares (which is shared across the three RAIDs) in a single storage pool (round robin-esqued), and you could plug that into a 2U with 16 small SSDs (like those Crucial M550 128GBs I use now) for the ZIL/L2ARC farming, and then have, well, near-infinite IO performance. Good luck trying to assemble that with BTRFS.

> it cannot possibly mean A and not-A at the same time.

Here's an old joke:

A linguistics professor was lecturing to his English class one day. 'In English,'
he said, 'A double negative forms a positive. In some languages, though, such as
Russian, a double negative is still a negative. However, there is no language
wherein a double positive can form a negative.'

A voice from the back of the room piped up, 'Yeah, right.'

> no matter which definition one chooses, a word cannot simultaneously mean what people think it means, and the opposite of what people think it means, at the same time.

A word can have multiple meanings, and those meanings can be related, or unrelated, or contradictory, or anything in between. When a person uses a word, usually they intend one of those meanings, but you can also intend multiple meanings at the same time—thus double entendres. You can also say something, but mean something different, or even the opposite—thus irony and sarcasm.

> And some words have technical meanings that are contradicted by popular usage, like "theory" in science. Many people think "theory" means "hunch" -- "but it's just a theory, you know?" In science, theory has a specific meaning contradicted by the everyday understanding.

"Theory" has multiple meanings, some of which people are unfamiliar with. But their understanding isn't wrong, they just don't know the meaning that the speaker intends.

> synchronization has a specific meaning that many people don't know.

Synchronization has multiple meanings—thus why we have post after post arguing about which is correct.

Global shift to open source at universities
I recently wrote on my blog about the cost of having a benign mole removed. I got so angry when I heard the cost of that simple procedure that I went online and calculated the cost to do it in Colombia, where I have some family. Long story short, I estimated that it would be 34% cheaper to fly to Colombia, have the same procedure done, and have a full week's vacation (at hostel rates, which is how I travel). Everything, including airfare and a full week of food and lodging, for 34% less than just the procedure in America!

The best part is that I guesstimated the cost of the procedure in Colombia. But even if I tripled my guesstimate, it would still be cheaper to fly!

For time-insensitive or elective procedures, you can and should go abroad. The real cruelty is people who don't have a choice--emergency situations, cancers, etc. They're trapped in our hideous system and often have to choose between their life savings and a lifetime of debt, and dying.

Our American approach to healthcare disgusts me. Every time I think about it I get filled with rage.

Looks like the classic MVP page to test if this is a good idea. Seems interesting, but can you imagine the headaches of looking after 100 people, in 18 locations across the globe, in one year?! Coordinating jobs, visas, accommodation, people leaving, getting fired, personal issues, flights, buses, etc. I have taken coordinated trips with 90+ people on the same plain to remote destinations, and it takes months of planning for a single stop. You would need full time handlers.

ps. don't get me wrong, I like the idea, but you are likely going to burn these people out with tons of logistic issues.
Hi, I didn't notice this reply for a long time, but felt bad not to reply to something so long :)

1. Yes, good datasets exist. They grow over time and they are open. It takes a lot of time. ILSVRC is good example. There are many more: Pascal VOC, COCO probably best known among them.

2. The optima vary. Training set has huge impact and is super super important. Has to be large and varied otherwise you've lost even before you choose a model

3. They can be very fast to run. With a good GPU, the most recent convnets can run in few milliseconds per image

4. Everything is open and BSD/MIT, no issues at all. Models are often distributed, for example the ILSVRC 2012 model is included with Caffe framework.

5. The trained models are TRIVIAL for layman to use. But they are not trivial to train.

6. Yes there is a lot of specialized knowledge needed to tweak model params.

The summary is these models are now trivial to use - you literally give it an image and it gives you very good predictions for what's inside in a few milliseconds (or few seconds on CPU, not GPU). They are not trivial to train and understand, though. That needs time, practice and mathematical understanding. Caffe is the best framework to look at. Pretrained models are available for 1000 ILSVRC classes for classification and for 200 ILSVRC classes in detection, but not for many other tasks (e.g. scene classification etc.)
I remember that 800 number from one of the books about graphics and rendering. Forgot which one, probably Glassner's. So it might be more of a theoretical/ultimate threshold than anything. Also, it's not about resolving individual pixels but removing aliasing effects due to signal /picture density.

From the other comments you can see quotes from a version of the story showing that there was almost certainly no adultery.

The rest of your conjecture is mostly you applying your own bias to an absence of information. It's a circular argument to use that to support a sense of traditional values.

For all we know the previous relationship was years long and not at all casual. Unless you're going to interpret any non-marriage relationship as 'casual' I don't think you have any evidence in favor of your main point. Especially since this shows a sliver of failed intimacy utterly destroying love and marriage vows. It's not like the man was living a double life, this is something that never came up. To say that their multiple decades of intimacy were not good enough and this shows the true importance of intimacy is nothing more than No True Scotsman.

And I severely doubt that it shows the importance of sexual intercourse either. Just the importance of children, which everyone (to first approximation) agrees with.

The second line is the quote of the day for me :)
This is fascinating because the cerebellum is part of the "reptilian brain", one of the three sections of the mammalian triune brain that include the limbic and neocortex as well.

The reptilian brain is responsible for basic motor functions, heart rate, temperature regulation, and balance, and evolutionarily seems to be the part of the brain that is most connected to that of ancient fish and reptiles, as the name implies.

A person who is missing a portion of this rigid subsystem should still be able to think, process new information, and remember it, but might suffer from imbalance and other basic health issues as in fact this woman does. Yet, she can do lots of stuff. Apparently the surviving portions of her reptilian brain are able to compensate for the loss of the cerebellum.

It sheds a whole new light on a phrase like "my cold reptilian hindbrain tells me to ruthlessly proceed". We think of ourselves having this sort of emotionless hindbrain that is moderated by the more modern brain centers for sympathy, empathy, emotion, and higher reasoning. But what if in fact there is no such thing as a ruthless, primitive hindbrain and we are all completely in charge of our behavior, ethically and emotionally speaking?

Coming from India, I have really come to hate the medical system here in the US. There are countless times I have been screwed over by the lack of transparency in cost and the layer of bureaucracy and BS imposed by having to deal with an insurance company rather than __the doctor/hospital who treated me__!!

It has been a few months since I have seen a doctor, but I still receive some new goddamn bill every other day. They are usually cryptic and leave me wondering what the hell they are for, and why they were not just presented to me on the day of the test. Don't even bother asking anyone what a procedure costs. Hospital staff will redirect you to someone who deals exclusively with insurance (completely unnecessary if we just had simple bills like any other transaction FFS), and the insurance people don't have enough specifics to ever really give you an answer, not to mention the time it will take waiting on hold etc. When you are getting multiple procedures, its just not worth the time. So you are practically forced to go in completely blind about potential costs.

To top it all off, my insurance coverage has expired as I recently graduated. So my options are to either pay $600 for 30 days of medicine that I need, or get the exact same medicine shipped to me from India, for $10-$20. They produce it by the millions in blister packs. This should not be so difficult! If we just had realistic prices in the first place instead of inflating them and bringing them down with insurance, this crap would not happen.

And don't even get me started on "pre-existing conditions". What that means for me is constantly lying to doctors and being unable to give them a complete medical history - otherwise I'll have f* "pre-existing condition" stamped on my head and never get sane rates again.

I fail to see why health care is not treated more like a series of simple business transactions in an economic system instead of this colossal mess.

I was going to criticize this submission for adding a question mark to the original title, until I read the linked article. The article doesn't try to show an association between data analysis and reality, or use the term "evidence" even once. So the question mark is entirely justified.

>Micro-USB has an on-going issue with the plugs breaking

i believe this was actually one of the design goals of Micro-USB, and the reason it replaced mini-usb. People treat their devices terribly, and the end of a cable sticking out of a device gets a lot of force put on it. Mini-USB was designed to be tough enough to handle this, and was a pretty robust connector, however the devices that OEMs were integrating Mini-USB ports into weren't necessarily built to a high standard. So people torque their cables and break things inside their devices. Better to break a $6 cable than a $100+ device.

Apple can get away with a strong connector on lightning cables because they can make sure that the internal connector is correspondingly well-built. The USB forum doesn't have that control.
The US insurance system is heavily tuned to make some people pay for others. Employer sponsored insurance, together with accompanying regulations about individual costs, is tuned to make sure the smoker and the healthy person pay the same price. See also community rating in the private market. On top of that, the US government pays more for it's own socialized medical programs than most other nations do.

And this isn't even getting into all the ways regulations micromanage doctors and other parts of the system. Not to mention micromanage financial services - India actually has innovation in that space.

Any theories which claim that for-profit systems are horrible need to be tested against the Indian system. It's mostly for-profit, free market, etc - all the incorrect claims people make about the US are pretty much true there.
