White guy here. I grew up in rural Georgia and got out as fast as I could. I still visit every Xmas. While we've come a long way since Jim Crow, I still hear the n-word all the time. Not just from rednecks, but from educated people who are respected leaders in their community.

I think we're at least another generation away from that word being expunged from common discourse.
I am in principle willing to concede that, but I don't think it necessary. I am not willing to put the rights of the individual over the rights of the collective. Individuals do not reproduce -- we are not bacteria. There is a point where promoting individual rights is not useful where the species is concerned.

The concepts of "fairness" and "equality", are both fundamental to good societies. They also can only be defined within the context of a society: fairness and equality for one individual (or a sociopath) is whatever the hell he likes. You don't need the argument for individual rights in order to decry slavery, though it helps. Where societies are not fair or equal, they are not good. When individuals are not beneficial to the society they are in, they are not good. There are other measures of morality, but none so fundamental.
Call me whatever you want, say I'm wrong, I don't care, but I hate kinds of Email Marketing, no matter what, because everything comes with a catch.

Would I like a ticket with 50% off from Brazil to NY? OFF COURSE I WOULD! But I know that if you had to send a mass message about that, it certainly has a catch, so I won't even bother looking at it.
Universities had national census not only for Jews obviously. This doesn't preclude the fact of that it was manifestation of antisemitism. If you don't get it - there is little point in explaining it to you.

Note how NPR is one of the most right-biased in this result. It's pretty evident from years of listening that the NPR staff generally are progressives, and would left. So I think this result exemplifies how genuinely 'fair and balanced' NPR really is.
I didn't say one way is strictly better. There are tradeoffs to consider and that's all that really matters. I'm not sure it occurred to the OP that there are benefits to forgoing remote branches, so I mentioned it.

Probably not by much though.

Actually, I was somewhat pessimistic:

Angle subtended by Earth at a million miles: (8 thousand)/(1 million) = 0.008

Angle subtended by Sun at 94 million miles: (864 thousand)/(94 million) = 0.0092

Area of Sun covered by Earth: (0.008 squared)/(0.0092 squared) = 0.76

So about 76 percent of the Sun's visible area would be covered by the Earth. The Sun would be about 1/4 as bright from L2 as it is at noon on Earth. That's still very, very bright, but there is some effect due to the Earth.

Also, it's worth noting that the most dangerous radiation in interplanetary space (solar wind and cosmic rays) is not "shadowed" by the Earth in quite the same way visible light from the Sun is. The Earth's magnetosphere does have a "tail" that extends behind the Earth, but there is radiation inside it.
That sounds like a good deal for both parties. I wasn't sure if you guys would be taking equity in the businesses for the $500, which is why I asked. Thanks for clearing that up.
> Affirmative action is not the same thing as making it artificially harder for a discriminated minority!

It is practically the same. When it comes to limited entrance, you can't make it easier for a certain group without making it harder for the rest.
Consider forgoing long-lived/significant local branches too then. Branching has its downsides, and avoiding it has some upsides particularly for small teams. As an alternative, you might start using feature flags instead. Look into "continuous deployment" as well for more insight.
Deep within the 1000+ comments on the accompanying reddit thread is a really interesting fact: Reddit is not (currently) profitable. [1]

I was already a reddit gold subscriber, but the fact that at the moment they're literally running into the red to provide cool stuff like the Obama AMA makes me want to subscribe again. Anyone looking for a reddit gold account?

If it was truly great stuff, I would be okay with that. As many others have pointed out, spending inordinate amounts of time researching every possession might not make for a great life. But why not let someone else do it for us?

If one person gets a reputation for integrity and publishes the best of each category on a website, with links to buy, great. And I wouldn't mind them taking a cut. Isn't that part of what the web is for?

Not really. It would just be an incremental improvement in nuclear fission. A traveling wave reactor would probably be better as it would use existing depleted uranium as fuel, and would produce abundant energy while making uranium stockpiles less of a problem.

Say everything you are thinking so they can tell if you get close to the correct solution. Be experimental and try approaches you think of even you are not originally sure they will work out. Try to spend time making your code exactly right rather than just writing something down and moving past it as soon as you think it is about correct. That is because they send the code you write to the folks who actually make the hiring decision. If they give you a 2d problem with real coordinates, think about discretizing the 2d space. Know how hashes and BSTs work. Don't worry about more exotic algorithms and data structures. They probably won't test you on them. Get nine hours of sleep (or maybe even ten) before the interview.
I work with both. You will not have any problem working with OS X. Some APIs incredibly similar in most kind of applications. I would even calling 'learning' a bit of a stretch. You will pretty much just acknowledge, not learn (in a broader meaning of the word).

Career wise, It will matter only if who is hiring you don't understand how similar iOS an OS X development really is.

How China Picks Its Leaders: A Chart
There might be something wrong with the plot http://www.strangeloopnetworks.com/assets/images/AverageLoad... , since it looks like a unimodal gamma, beta or log-normal type distribution, but the seconds are on the vertical axis. Did a random ordering of sites along the horizontal axis just happen to end up looking like a gamma distribution? Highly unlikely.

So what does the plot mean?

Looks like nonsense.
My story: at 36 years of age I went to live in Italy... after 13 months my weight went from 92 to 98 kg and BMI from 25 to 27 (yes, I blame the delicious Italian food). I carried the extra weight for 8 years, and ended up with a 160/90 bp, and a variety of minor health issues (posture, sore knees etc). I made a number of attempts to return to 90-92 kg weight, typically around serious exercise. That worked until some disturbance in my life, eg business travel, spoiled the routine - I found it was much harder to restart the exercise than to keep going, and typically ended up putting on weight again.

Today I am back to 92 kg, and off bp medication, with a bp of 120/70. What worked for me in the end was a combination of a few things, but I think the most important one was this: do not treat food consumption as a form of or a substitute for entertainment!

This manifested for me in snacking on sweets when things were going slow at work, eating to excess at restaurants, snacking while watching movies etc. These habits were actually really easy to kick, once identified.

One other easy but significant change: I bought a soda syphon (like this one:http://www.ebay.com.au/itm/280607022341?hlp=false). I reduced my soft drink consumption by at least 90%. I find carbonated water delicious, and now Coke et al taste unbearably sweet. Judging by the CO2 cartridge count, I drank abt 200 liters of carbonated water last year... that much Coke would be roughly equivalent to 10kg fat, calorie-wise.

YMMV, of course, but perhaps the above can provide another tool in your good health toolkit!
> Also I believe you are assuming the race of the parent. For all you know they could be a member of a racial minority.

You believe incorrectly. I did my homework.

http://geekpolitics.com/wp-content/uploads/2008/12/derekclar...

But the rest of silliness about white people having it harder than minorities was the giveaway.

> The opposite is also true: "Absent significant study, it is absolutely not the place of someone who is a member of the racial minority to declare the extent or impact of racism." Why not say simply it is not the place of someone to declare the extent or impact of racism without study?

Being a minority can be a graduate level course on the extent and impact of racism. In America, most blacks and hispanics have had ample time to study up, sadly. And if you're from anywhere in the vicinity of the Middle East, god help you.
It's weird for a libertarian to be praising the progress made in the 50s and 60s, a lot of which was the result of huge defense-related government investments.

His economic history doesn't make sense either, implying that there were no bubbles and busts before 1970.

And, as others have said, he is minimizing huge gains in a bunch of other fields.

Weird article.

Did you read the popup saying you need to register?
Principally yes, but I'd disagree on essence.

Say you have a minority that's 1% of the population, and unhindered it would also make up 1% of enrollments.

If you don't allow that minority to enroll, you're increasing the acceptance chance of a majority group member by just over 1%, while decreasing the acceptance chance of the minority member by 100%.

The correct way to describe this is then most definitely discrimination against the minority, and not affirmative action for the majority.

Everyone tends to respect Kasparov because of his amazing chess prowess. He is also a very active and involved person in the world - just look at his activities in Russian politics.

Unfortunately when you get outside his area of expertise, he often combines confidence and ignorance. The best example is http://www.revisedhistory.org/view-garry-kasparov.php where he tries to argue that about a thousand years of history did not happen.

His arguments are, of course, all bunk. As will be obvious to anyone who has passing familiarity with the serious famines due to climate change in the 1300s, the impact of the British agricultural revolution on food production in the 1700s, and the widespread use of abacuses for calculation until the introduction of Arabic notation.

This article is superficially reasonable, but similarly bad. Major tech advances in the recent past - many of which we'll see changing our future - include gigantic magnetoresistance, practical genome mapping, memresisters, continued improvements in battery technology and practical analysis of large data sets. (Enabling technologies like facial recognition, automated translation, and the like.)

The more you look, the more there is to be amazed at. Did you know that there is a serious effort to create a handheld device that can take a small tissue sample and identify any species on Earth? We've done DNA analysis on a t-rex, and there are people trying to get funding to bring mammoths back to life.

Experiencing it day by day we take it for granted. But looking back from the perspective of 50 years from now, the list of changes will be major.
they say that actual observed data is unreliable so they'll use a made up model instead to prove their claims.

A better paraphrase would be "they say that accurate data on one part of the system are hard to get, so they compared several models using another, correlated, part of the system, for which better data are readily available."

Also, since their claims relate to which of 16 models match "actual observed data" best, it's incorrect to characterize their work as using a model to prove their claims. The models are the subject of their claims, not tools used to prove them.

Dancing with Harry Reid . . . Ugh
Having been in a startup before: I'm not sure how I feel about this...

In regards to getting features out quickly: that's a great programmer. Though inevitably there comes a time when the code needs to be maintained - and if it is unmaintainable then I'd put you in the bad programmer category.

Now-a-days: I prefer clean code to a specific coding standard over the quick, dirty features being implemented. But, only because it usually causes more pain in the long run. I understand the "getting a feature out quickly to test it even works" mentality, and to some degree I agree with it. However, if it DOES work then a clean code base is always better. Inevitably it will need to be maintained...

After writing this (sorry: could rewrite my comment but decided not to) I've now realized that I'm now AGAINST the feature push mentality. I'd much prefer well written code and eat up the cost then rather than later on. Worst case scenario, it can then be reused...

The Awkward Leader
Because there is no number. The premise is flawed. This is just such a nonproductive outlook to have. How far back do any of us have to go before we find our ancestors living in tyranny or serfdom or slavery. For many of us, not too many generations I bet. What does it have to do with our lives, today? If you go looking for a reason to be a victim, to find justifications for your problems, you'll never get past them.

Let's say I discovered that my great great grandfather was a slave. Let's say I somehow got paid $250,000 for that. What could I do with that money? If I'm careful, I could live on it for four or five years, maybe a few more, likely a lot less, then it's gone, and where am I? Right where I was to begin with.

I don't think he is arguing that the existing pace of scientific advancements are too slow. Rather the adoption of of these advancements need to be accelerated.
The article is suggesting that the current investment strategy over-allocate resources to existing technologies, instead of developing new ones that better leverage the advancements in science.

Using the railroad system as an example, yes we have the technology to build trains that can travel 350kph, but how much of our resources are still being allocated to trains that only go up to 60kph compare to the more efficient alternatives
