It is very easy to bias a coin. Ask any stage magician. You can bend them, you can taper the outer edge, you can cover one side in a thin layer of something bounce-deadening (like rubber cement), et cetera.

There's a big difference between "you can't bias a coin using weight" and "you can't bias a coin."

I completely disagree. Fedora seems to take OS X and make it much more usable and more intuitive and it cuts out the cruft.

Any cursory glance of any Windows forum on the internet will show you that it is indeed not more usable than any of its competitors.

I've personally set up children and elderly people with Fedora and it's orders of magnitude better than Windows in these cases seeing as it's almost impossible for the average user to mess up.

Perhaps installing Fedora on your mac book was a headache, but have you ever tried to install OS X on non-apple hardware? It's worse than any other OS. If you bought Ubuntu certified hardware (as you did with Apple) you'd have no problem with Linux, so it's disingenuous to compare the two.

Sorry, but Windows isn't an OS for "normal" people, it's an OS people use because they have to for some reason (games, work). It doesn't "just work" and it's not miles ahead of any other OS, and certainly not more stable. I've had my Fedora desktop up for months at a time without anything crashing, this typically can't be said for Windows in my experience.
Isn't that pretty much why we have welfare - to give the poor protection money to stop them attacking? Sure, you could spend more on police, but it's probably more cost effective to just give poor people money to keep them a bit more docile.

I can also run a full UNIX userland on Windows, z/OS or OS/400, that doesn't make them UNIX.

And I doubt IPC will work anyway, given that the Android kernel doesn't do UNIX IPC.
It is unfortunate MS turned OS/2 2.0 into an entire fiasco. There is a reason why it is my favorite topic.
Along a similar line. Here's a very interesting show from 1978 about the "rise of the microprocessor".

Perception of Perfection
On OSX there are a ton on Apple services phoning home for all sorts of reasons, all the time. Try installing Little Snitch some time and be amazed. And I wouldn't be surprised to see the same on the iOS devices. Any Apple device is super noisy on the network with just mDNSResponder alone.

Most of them are also for useful features, it's just that they are all talking over the wire and potentially exfiltrating user information. I don't think that people realize how much data is sent around all of the time.

Here is a non-exchaustive list just to give an idea:

* locationd -> gs-loc.apple.com:443

* apsd -> .push.apple.com:80,443,5223

* mapspushd -> .ls.apple.com:80

* UserEventAgent -> :80

* ntpd -> time.apple.com

* ocspd -> :80,443

* ...

I didn't put all services. Notice that some data is not even encrypted.
A similar memset bug happened in glibc too.
At a workshop I attended, American piper Kieran O'Hare was once decrying the typical American "intensification" pattern as applied to seisiúns. It becomes about people's egos and shoehorning in their sets or showing that they can keep up with the best. Really, it should be about friends socializing and sharing music. Tunes-tunes-tunes-tunes is antisocial and a bit mechanical when it comes down to it.

At another workshop, Kevin Creehan (Junior Creehan's grandson) noted how it was strange for seisiúns to end up in pubs. Originally, they were in people's houses. They were intimate gatherings of family and friends, and some of the heights of artistry in Irish trad music clearly stem from this quieter and more intimate context.

For the most part Bay Area seisiúns seem to include a healthy dose of socializing and human interaction. Haven't been down to Mountain View yet. I hear those guys play fast. O'Flarety's in San Jose is pretty raucous, but even so, they manage to get in a good amount of socializing.

You techies that show up to The Plough and the Stars sessions -- know that you are in one of the premier sessions in North America, both for the skill of musicians and the health of the community that surrounds it. Don't expect to be entertained, like it's a show for you. It's a gathering for the musicians to share music with other musicians. If you like Irish trad, listen carefully, because the very best music comes out when it's musicians sharing with their friends. (Also listen patiently, because there's still a certain diversity of musicianship.)

Also, when someone is singing a slow air, then it's good manners to be quiet and listen! (And very bad manners if you don't!)
Twitter now previewing and omitting URLs in tweets
Before today, tweets with URLs might have metadata pulled to get a preview image and/or caption to show in a timeline. Now, that is still occurring, but if metadata is available, the URL is omitted from the tweet. Interesting.

Children from low-income households tend to have poorer academic performance and lower standardized test scores than kids from higher-income families

For me this part is totally wrong, Dummy comparison, I don't know Scientist who's father was billionaire or even millionaire. Some of the kids from high-income families are even spoiled a lot (thinking about Paris Hilton).

My academic performance was at top 1% at school, but I was almost at the bottom when sorted by family income.

Its not poverty changes brain, its your parents mindset change your brain.
Miners and exchanges.
>found that kids living in households just above the federal povertylevel had gray matter volumes that were 3 to 4 percentage points below the norm for their age group. The lower volume was concentrated in the brain's frontal and temporal lobes, regions that are implicated in behavioral and learning problems. Among kids living below the federal poverty line, gray matter volumes were 8 to 10 percent below the norm. On average, these kids performed 4 to 7 points worse on standardized tests.

A partial explanation could also be that they grew up in poverty because their parents were too genetically stupid to earn good cash / living within their means. I think this hypothesis is supported by adoption studies.
It's a perfectly legitimate thing to ponder, even in movies like Denzel Washington's "John Q", and Amazon Billionaire Nick Hanauer's essay "The Pitchforks Are Coming (For Us Plutocrats)" [0].

If you bury your head in the sand and pretend that people will never break the social contract because "inequality doesn't matter" and "macroeconomic indicators look fine", you're going to miss a big part of the picture.

A lot of it's basic ideas did even with OS's that aren't Unix or Unix based. Everything is multiuser, multitasking and network based now.

OSX along with iOS which controls a large part of the mobile/tablet. Android has it's Linux roots too.

Windows NT set MS up to finally switch to a better OS and discard of DOS based Windows.

The server space continues today to be run by Unix based OS's (Linux, BSD, etc).

What's really interesting is that in 1985 when this video was out, Next was just being formed and they were building NextStep.

It would be interesting to see a side by side comparison of people coding for the exact same output, and the time difference between them. If React is supposed to make coding faster, then why is the code a black box? Why do I have to debug the React source code to find out what's going on. Too much div soup, too much abstraction. I genuinely would love to see a code-off between developers where they make a simple TODO app, with one in vanilla JS and the other in React. Presuming the React developer has mastered React and won't run into some form of roadblock (which is rare).

Not advocating the murder of innocents is burying my head in the sand? Fascinating.
Because people have an innate sense of right and wrong. The concept that you should not kill someone else in order to take with they have has been shown to be almost universal across time and culture.
The solution is to not buy anything which is advertised, sold through cold-calling.

We could learn something from developing countries and some developed countries. They have open markets where people go to buy stuff. Humans have been doing this for thousands of years. You can haggle with the vendors and examine the products for sale. In the US, these open markets in a city center do not exist (Maybe except for swap meets and farmers markets)

Would it be possible to do this on the Internet and cut through the vested interests? Instead of advertising, when one needs a product or service, he visits a large scale virtual open market/bazaar where he can talk in real time with the vendors see videos of the product, and haggle on price.

To me, advertising is mostly pushing products which people want and do not need. Advertising is expensive. If most people didn't respond to advertising, the things available for sale would be of better quality and at a lower price.
> React is ONLY THE VIEW LAYER.

> React gives you a template language and some function hooks to essentially render HTML.

This is actually wrong, despite the official page saying the same. It's the biggest misconception in the React community. render() function outputs a data structure which describes HTML and ALSO user event handlers on that HTML. Any UI program does both: handle input user events and generate graphics output. A View is only the latter part, hence React cannot be only the View.

Refer to original MVC paper http://heim.ifi.uio.no/~trygver/1979/mvc-2/1979-12-MVC.pdf

Perhaps the issue is actually with your provider? In practice, HSPA+ (3G) usually allows for 20Mbps in my experience, which fits right inside your 10-40Mbps LTE window. Going from 20Mbps to even 40Mbps really isn't going to be noticeable in many circumstances. In theory, HSPA+ actually allows for download speeds greater than LTE allows, although less so on the upload side.
The article says that the flip should be caught and not allowed to bounce or spin on the ground.

It still seems to me possible to bias it with weight, based on angular momentum. I think a cavity internally that went from the center of the coin towards one side, with a small weight that moved up and down freely would cause one part of the spin to go faster (when the weight was in the center) than the other part, and would cause a bias if the spin were slow enough not to keep the weight locked at the outside (maybe a spring would be needed? Turns out I don't have a good intuition for what happens when you mix gravity with fast rotation)
Did you have to do anything special when maintaining your bike?

The Bitcoin XT software was designed to "poll" miners and ignore the other stakeholders. Mike Hearn explains why at

http://lists.linuxfoundation.org/pipermail/bitcoin-dev/2015-...

Even though the other stakeholders will certainly be able to make their preferences known to the miners, any effect the other stakeholders will have on the success or failure of the fork will be through the miners, which IMHO makes my statement "it's the miners who are being asked to vote with their feet" correct, at least for a sufficiently narrow definition of "vote".

Even when we consider the situation more broadly, none of the other stakeholders have (as far as I can tell) as much at stake as the miners. The miners for example might be hoping that if the 1-meg limit remains in place, transaction fees will become a significant fraction of mining rewards, which would increase the total income of mining (income being essentially the built-in rewards, which are not affected by the fork plus the transaction fees). Holders of large positions in Bitcoin on the other hand -- what is their reason for preferring one fork or the other? Ditto merchants who accept a lot of Bitcoin transactions.

ADDED. As far as I can tell, the designers Bitcoin XT sofware have done what they can to minimize the distruptiveness of the fork on the lives of the other stakeholders -- by, e.g., refraining from doing anything to affect anyone but the miners till 2 weeks after a full 75% of miners (or 75% of hashing power -- not sure which) are running the XT software.

ADDED. Yes, I realize that any additional income gained by the miners will be paid by Bitcoin senders (e.g., people using Bitcoin to pay for things), so in that sense Bitcoin senders have just as much at stake as the miners do, but transaction fees will always be a very small fraction of the costs (considered collectively) of the senders of Bitcoin, so this is another instance of the very common situation where a large number of people are affected in some very small way by some policy decision whereas a smaller number of people are affected in a more significant and material way, and we know (from experience with democratic governments) that what usually happens in that situation is that the smaller group (whose interests are "concentrated") has a much larger influence on the decision than the larger group (whose interests are "diffuse").
The first few paragraphs strike a chord, but don't propose a lot of answers, and the end is just a collection of destinations: Why do we travel? (Am talking about recreational travel, not business)

A friend of mine was mentioning incoming holidays, to which I asked an open "Anything planned?" question. In her answer there wasn't even the _mention_ of planning to travel, it seemed such an evidence that she just started listing potential destinations, to the point that I got a you're-such-a-party-pooper look when I asked if she considered something else from traveling. This, and a few other similar experiences with friends/colleagues who consume all their time off traveling.

Of course, these are just a few data points, and maybe there's no generalization to do (some people like to travel a lot, some less, fair enough). Also, I traveled a fair share too and generally enjoyed & learned from it, but so do I when I simply spend holidays staying in my hometown reading, socializing/partying with friends, spending time with loved ones, coding, gaming, and resting.

Now, focusing on the population subset that does feel this urge to always travel, what are the most common "why" for this? Difficulty to "disconnect" if still close to their daily routine? Pure habit? Social pressure? Fear of being unable to find anything meaningful to do and end up disappointed about themselves? Are globe-trotters simply better at feeling energized and reaping benefits from travel that I do?

As an aside, will we start to see these travel binges less leniently (and consider less fuel-y alternatives) when we start realizing their ecological impact?
A partial explanation could also be that they grew up in poverty because their parents were too genetically stupid to earn good cash / living within their means. I think this hypothesis is supported by adoption studies.

And a partial explanation for why you believe this is that you've been indoctrinated and propagandized and peer-group socialized into believing this. See the studies that compare incomes between adopted and biological children and adoptive and biological parents. Environment is by far the determninant.
What I'm about to say is not about that article, but just a general point.

This is that the printing press "only" made it quicker and cheaper to make books, and the internet "only" made it quicker and easier to move information around... So improvements that can be characterised as only incremental can still be important.

> Its not poverty changes brain, its your parents mindset change your brain.
This is my experience. I grew up in "poverty", but my parents spent a lot of time with me, and now I'm a sysadmin making a decent living.

Also, I never actually felt poor growing up. Sure it would have been nice to have a video game console or more movies, but I never felt like I was really deprived just because I didn't.

I don't remember ever fearing that I wouldn't have a roof over my head, or food on the table. I think the only times we might have been close to that, extended family took us in.

So, from personal experience, strong families are the best way to fix poverty.
Yep - causation != correlation - being poor in it of itself doesn't cause academic performance. It's the parental values, diet, distrations found in low income communities etc that cause poor performance, not just being poor.

Also, I think that the author meant middle class / upper middle class when he talked about "higher-income families" - certainly, in my university the majority of the kids are from upper middle class families.
I use R, and I still use ad-hoc commands from time to time too. I guess mlr and xsv lie somewhere between, which I've personally never really considered.

R is specifically designed for manipulating datasets though, and has a lot more functionality/dependencies. If you're already familiar with the language, and okay with the dependencies, it is vastly more powerful, more succinct, and arguably easier to use. Otherwise, something in between probably still makes sense.
This is one of two videos that are excellent (I've used both during teaching).

The other is "Brain In The Box" filmed at Manchester Uni during the 50s*. In BitB, apart from giving an excellent low-level view of how computation actually works, the interviewee sets out how computers would have to get smaller in order to get faster. Keeping in mind this was a decade prior to the microchip, he showed a small cube (about the size of four standard Rubix cubes) and compared it to the current room filled with (what I think was) the Manchester Mark 1 [1]. (This one is quite difficult to find, though. I grabbed it when the BBC Archives were briefly made available as part of a trial around 2006.)

From this video, the most interesting part for me is the discussion at the end. At around 1h14 Rick Mclean (sp, basically a 'think tank' member) says that in order to deal with the existing "work ethic" in the face of massive unemployment due to automation, the country would need a produce a generation who "didn't want to work" and wouldn't mind not having a job.

Cue the next 30 years of social policy?

"Higher-income" is not exclusively millionaires and billionaires, the article specifically states this: "Gray matter volume in kids from middle-income families did not statistically significantly differ from that of their richer peers, suggesting a poverty-specific effect."

As far as I can tell from skimming the article, there doesn't seem to be much causal inference going on: "It's not clear what, specifically, about poverty takes a toll on brain development." Seems like a great observational study to me--it doesn't jump to conclusions and opens a lot of questions that need to be answered.

Genes are by far the most important factor. If you've bred animals, you'll understand this. Take a couple of poor animals and breed them. They'll have poor offspring. You can do all you like in their environment, but they'll still be poor.
Select high quality parents, and you'll have high quality offspring. Selective breeding works extremely well to produce the best quality animals/plants.

I have no idea why we're in an age where it's so un-politically correct to say this about humans.
