From what I read, it looks like the policy would apply to work produced 'for the school' or use by the school or part of the school, or with school equipment. So I suppose if you claimed all work you turned in had been produced by you prior to the assignment, for your own, or other, purposes, you (or the copyright owner) would retain your rights.
I used to live in Greenbelt, in the heart of PG County, and my 2-bedroom-and-den semi-crappy apartment cost $1750 nearly 7 years ago. And Greenbelt is a DUMP. An expensive, expensive dump.

Since the apartments were all full — and not 6 people to a unit, either… -- there's only one conclusion… PG County is a lot wealthier than you think. It's not all in Bowie and "the north."
Also look for Seneca. In particular I liked "Letters From A Stoic".
Funnily enough, I remember Blue Moon better for SkyRoads.

I wrote a semi-clone of it in Qbasic (learning a bit about 3D projection on the way). I later ported it naïvely to Python and it ran slower. :D
I never know from stories like this if law enforcement are hopelessly clueless or if they do know what they're doing but just not releasing details.

While the tech is probably secure it's easy for people to make mistakes that leak information; and while NSA or GCHQ probably find it easy to get that information they have no interest in doing so. So, do police agencies have people who know enough about the mistakes people make with Tor and Bitcoin?
I second this. But don't take my word for it. Here is 5.24 (one of my favorites) translated by Long:

"Think of the universal substance, of which thou hast a
very small portion; and of universal time, of which a short
and indivisible interval has been assigned to thee; and of
that which is fixed by destiny, and how small a part of it
thou art."

And by Hays:

"Remember:
Matter. How tiny your share of it.
Time. How brief and fleeting your allotment of it.
Fate. How small a role you play in it."
That implies one of the following:

1) The printer is capable of "printing" complex compounds using individual atoms

2) The printer is pre-loaded with cocaine, LSD, MDMA...

My point being not everything can be printed...
Magie wasn't voted into power over and over by 'the elite classes'. The fact is we had no credible alternative at the time. Michael Foot's Labour Party? Really?

We still have fundamentally the same economy she built, and it's served us well. Thank goodness New labour had the good sense and survival instincts to essentially leave it well alone. Apart from bankrupting us of course, but hey, plus ça change.

> There are countless therapies that are dangerous and/or ineffective and plenty of unscrupulous or incompetent people who want to flog them.

There are countless regulatory policies that are dangerous and/or ineffective and plenty of unscrupulous or incompetent politicians who want to flog them.

So what process validates the "safety" and "effectiveness" of the FDA's universal-scope regulations? Certainly, given that you and I can't opt out of them as we can with drugs and medical procedures, the danger of bad policy can be far graver than the danger of bad medicine, yet there's no regulation of regulatory policy at all!

I understand the desire to protect people from fraud and deceit, especially when the consequences of bad medicine are literally life-or-death, but surely the proper way to accomplish this end is to supply people with the data that will allow them to make informed decisions, rather than usurping their right make decisions in the first place.

The FDA should function as a certification body, evaluating drugs and treatments, and informing patients as to the likely results of using each, but it should not have the power to prohibit anyone from undergoing any treatment or taking any drug.
I am going to run afoul of the common thinking...but this is one of the reasons I really value my liberal arts degree. I was exposed to a wide variety of disciplines and forced to spend time digesting them. You can certainly walk yourself through a philosophy of ethics class but a lot of the value was having the professor walk us through things, guide the resulting discussion and ensure a certain level of rigour.

My favorite philosophy reading was Plato's Republic.

Text: http://classics.mit.edu/Plato/republic.html

Discussion of politics and ethics: http://plato.stanford.edu/entries/plato-ethics-politics/

Plato generally: http://plato.stanford.edu/entries/plato/

Geeks, nerds, tech people: we seem to have ended up with a fair amount of global influence.

I know a lot of us are into -- or getting into -- some kind of "traditional wisdom," even if we're not traditionally religious.

For me, Buddhism resonates strongest, so I'm walking that path.

Whichever path, by walking it, you affect the world. Living ethically is a great gift; it makes you a source of safety and peace.

And that shines through in your work, and many of us have livelihoods with global effects. That's a powerful fact.
Talk about bad press for Bitcoin. Silk Road is probably the number one reason regular Joe's would ever hear them mentioned.
This is extremely unfortunate - I can see the way the C++ committee argued about this issue (ie. having consistent "erase" interface across different data structures), but it's bound to backfire for many unaware. Especially in a hash table, where you conceptually don't expect erase to provide the successor.
I ran into the same issue with vim in a terminal. I decided to give gVim a try and I really like it. I used to use the sp and vs commands but now find myself using the tabbed windows in gvim. Try typing :tabnew for a new tab and gt for cycling through them.

There's a big difference between granting the school a non-exclusive copyright licence (including one that allows them to sublicense to anti-plagiarism companies), and assigning them your copyright. I'd be happy to do the first, but not the second.
Interestingly, most of my friends and colleagues who made the shift from iPhones to Android phones during the vast gulf between iPhone 4 and iPhone 5 are looking to switch back, due to app quality and availability issues. So at least for the narrow (CS BS+-degree) people that I know, I'd argue with his statement about the trend in Android desirability.

I do know quite a few people who are happy with their Android devices, but they all either work at, are significantly supported by, or are trying to get hired by Google.

Another great translation of these is by two brothers, David and C. Scott Hicks. It's called The Emperor's Handbook[1], and is an attempt to translate them in a way that is less literal and more "in the spirit" of what Aurelius was trying to convey. I definitely suggest it.

I sort of agree and disagree with you.

I think in Apple's case, strength relative to competition is a little redundant because if you're buying an Android tablet, then you're generally not buying a Apple tablet.

In Amazon's case, on the other hand, a lot of people consider their competition to be Walmart. Still, I (and many other consumers) shop from both places simultaneously.

Amazon can get stronger without Walmart getting weaker; I wouldn't really say the same about Apple and Apple's competition.
Heh awesome post, and hell yeah.

I work making games, I never figured the point of using unit tests.

Also yes, multiple inheritance and that shit is pure evil... Once I tried to make a game engine using very strict OOP. It took me two years to make a barely working game... It is great to impress employers, but I don`t plan in ever writing code like that again.

But I won`t say this is not only good thought. I feel many times that I should know more, even if is to know why I am not using it.
Yeah - that's life, the people who will tell you what to do next are few and far between, and you need to demonstrate that you deeply care about them (possibly in ways you don't yet understand) before they'll reciprocate the favour.

And am I confused here? I'm interpreting std as the namespace in which most of the C++ Standard Template Library lives. I assumed you were using them synonymously, because I've never heard anyone refer to std as anything more than a symbol used in STL code. Maybe there's a different acronym I'm not aware of though.

I'd like some clarification on Tor, please. Namely, how can the silkroad's site operate without the owners being detected? AFAIK Tor has its own DNS with <hash>.onion, but don't those resolve to regular IPs? And if police have a normal everyday IP, can't they just imprison the site's owners directly?
I don't do this everyday, I do this when I get the blues, and it usually cheers me up. I like to walk in an unfamiliar road, go to a place I've never been before.

I blog and whenever I hit a lull, I find that a walk or run is what gets me back on track. The chaos in a normal work week, the number of meetings, the constant context-switching all leads to little chance of forming coherent string of thoughts that can be used to construct a blog post.

Walks and runs also help in uncovering new ways to look at things, asking new questions that previously lay just beneath the surface, and letting your mind wander till they serendipitously uncover these nuances - those are the reasons I find time to do it. Everyone needs those quiet hours - when your mind could be free of clutter, and you could take a strand of thought and examine it more closely than you could have - when there are a hundred things vying for your attention.
Ah, but we do know more about the world in many ways than the original Stoics did. William Irvine's book recasts the Stoic teachings a bit: we don't believe that we were created by Zeus, for example, so he talks about how to interpret Stoicism in an atheist way (if one wishes).
Ask HN: Why my Ask HN is gone?

Very diffeernt styles but I'm not sure how I would choose one over the other. I don't know which is closer to the original.

> Where is Amazon going to suddenly start making money to justify its market cap?

This question seems to be asked a lot, and I don't think people understand what they're asking. Market cap is shares times share price. That's all it is. You can use it as a proxy for net worth, but you don't have to.

Fact is, what goes up must come down eventually, apple has been riding on the back of seriously good innovations for a while and they possibly were overbought.
The market gets jittery when it sees a stock to be over bought, no one wants to be last in, like if you bought a house at the top of the boom, so a pull back share value for now is frugal.

Apple's cash may flow freely, but unless they innovate further, they will lose market naturally.
Personally, I think the market expects another innovation akin to iPod, iPhone, iPad.... To me I can't see their next step
But I do hope they have one!
They are direct competitors

I guess I don't see it that way, but reflecting I guess my view is distorted.
Arguing from principle likely won't get you very far with people arguing from assumed utility.
1. Why are they or why am I? I won't be pushing any certain CMS. As long as the right tool is used for the job. Management is against open source for the stated reasons.

2. Website is informational as well as used for typical financial services. Go to any top financial institution, whether banking, insurance, or investment to get an idea. Obviously my coding will have to go through many channels, but I also realize that before I even get started I could help modernize their workflow. It would be kind of radical but I don't see any reason why the workflow couldn't match that of the more interesting tech companies.

3. Right, I totally get that. Maybe there's nothing to be gained in this regard, but I want to be creative in giving back to the community if it's even possible. I see startups like Simple Banking and their use of Github and I don't see any reason why the same couldn't be done in larger companies with the lead and support of the development teams.
>Where is Amazon going to suddenly start making money to justify its market cap? Suddenly increase prices and thus profit margins? Their competitors will eat them alive. Grow their business? Who isn't shopping online with Amazon already? It's just nutty. Their entire business plan is selling razor blade handles at a loss so they can sell you razors at a wafer thin margin.

Amazon has its challenges, but so does Google, Apple, Microsoft and every other corporations in existence. As for growth, there's plenty of opportunities for Amazon. They have their nascent streaming media business, digital goods (like books) to sell, grow their tablet and phone (?) business, build out AWS and cloud services and continue growing their online-retail market share domestically and internationally.
Relative to competitors is mostly irrelevant - if Amazon is the last man standing, but has shrunk 50%, you still lost 50%.

Yeah, but if you are primarily wondering where to put your money, it is relevant! If it's "Invest in Amazon" vs. "Invest in Amazon competitor", Amazon outperforming the competitor is much more important than Amazon's absolute performance.

I heard Amazon is bout to get around to being able to distribute from within the state California and thus be able to offer same day shipping with storage locker locations for customers to pick up from. This could be huge and could be the next step to Amazon to being the next big thing.
Indeed; thanks for the update on the US.

I believe The Economist paid lip service to the role of the financial sector in the collapse; but that's mostly my opinion; as you say, they definitely covered it to some degree. At least they're apparently starting to realise that chanting "cut public services" over and over isn't the answer.

One problem with the USA left-right false dichotomy is that when you pick a middle point between the Republicans and the Democrats, you end up with something that resembles no political party anywhere else (including in the USA's history); everyone else's right wing parties (and the Republicans in the past) resemble the Democrats or are even further 'left'.

As far as I can tell, there's almost no difference between Obama and (for example) Reagan based on the left/right scale; yet US conservatives generally idolise Reagan and demonise Obama. It's bizarre.
"So, do police agencies have people who know enough about the mistakes people make with Tor and Bitcoin?"

I met a researcher who did some work on attacking Tor, the results of which were given to law enforcement agencies. He was a bit light on details, but the basic idea of his approach was this:

1. You narrow down the geographic location of your target. Not hard in the case of the Silk Road, since there is a physical package being shipped.

2. You connect to your target's system, and modulate the latency of packets that you send. This is a covert channel.

3. You have a van rolling around the geographic region you believe the target to be in, and listen on wifi frequencies. When the covert channel is detected, you home in until you have located the target computer.

Obviously you can defend against this sort of attack by just not using wifi, although similar attacks at the ISP level are possible. Cover traffic helps with this, assuming the covert channel has low tolerance to noise (this may not be true; again, few details were given). It is also wise to avoid connecting from your house, if possible, and to use a public location where you can quickly shut down your laptop when you see the cops.

Or, you know, you could not sell large quantities of illegal drugs over the Internet, since it is basically asking for trouble.
Sorted arrays are a common choice that I've seen people go to in lieu of std::set, but a proper B-tree implementation kicks butt compared to a sorted array for performance when mutating data, and actually an unsorted array tends to kick but for small array sizes (<100 elements).
I doubt this is about profit. It's more likely that they wanted the copyright so they can use services that detect plagiarism without having to get consent from the students every time.

Now they're saying it's all a big mistake. Not sure I believe it.
It's really weird for you to jump to that conclusion.
The only "good press" Bitcoin could get is if a major government started accepting it for tax payments, which is less likely than Chris Dodd being investigated for bribery.
Pixel-fitting screencast
Because I thought Dustin Curtis' great article (dcurt.is/pixel-fitting) needed an extension. Subs in both English and Spanish provided.
I read the entire article; your comment is pointless and unconstructive.

My comment wasn't especially well-worded or clear, but loaded with a fair amount of sarcasm which some people have trouble with, so let me try again.

The Economist is a Neo-Liberal rag. 6 years ago, they would NEVER have published an article like this. Now they're starting to consider actual evidence and are seeing that government social services don't necessarily send countries broke.

However, they still have a long way to go before their analysis actually mean anything. Because they're still strongly attached to their broken neo-liberal world-view.
Prosecutions are public in many countries, so we can use that as a metric. If they knew what they were doing I imagine we'd see dozens or hundreds of Silk Road-related prosecutions. Or maybe Silk Road is mostly used by people who are too small-time for the police to bother with.

The FBI has an internal "manual" on Bitcoin that leaked a while back and they certainly have the skill to use various pre-existing open source tools to link addresses with names. In this case I wouldn't be surprised if Australian customs did most of the work though.

Stoicism is like Buddhism without the sitting meditation fluff.

I'm halfway through Meditations, and I do find that there are similarities. But when you look at intense practice of stoicism vs. buddhism, they promote different goals. Buddhism encourages you to abandon a normal life to dissociate yourself so you don't have to be reborn. Stoicism seems to be neutral on what to actually do with your life, besides the broad "be a good person and grow yourself" aspect.
