Actually that's a fair statement as living expenses are equal to tuition in places like Boston. Add to that the opportunity costs of two years of deferred salary (on average close to or above six figures) and you're talking about a $400k commitment.

I'm right with you on your slactivism. I like the idea of being very involved in politics, but I just cannot stand (a) listening to politicians, or (b) talking about politics.

I just don't have the heart for the current discourse in the country. Every once in awhile, I'll try to go the good citizen route, look into the current issues, and then draw my own conclusion.. but what was all that effort for? I've tried my best to present logical rebuttals to people's points. I try to source only relevant, publicly available government data when possible, but it means nothing. The response I usually get? "Yeah, but.. still.." and then they go back to making their talking point.

"But still.." is not a rebuttal, people.

I spent several hours investigating the energy policy of the candidates. I pulled a bunch of charts from the EPA, compiled them all into an email, and then gave my armchair analysis of the policy given the available data. I was told that "I'm missing the important issue."

So... fuck it. I'll just go back to studying.

Software development is important, but it's not everything. People choose what works and use it.

Though I agree that spreadsheets won't always work on Big Data, there's no point in doing more if you can achieve it with less.
Do you happen to know a resource that explains how you do this?
Ask HN: Where do you freelancers find your clients/work?
I know a lot of freelancers find their clients in different ways. I want to see what advice you have for someone looking to land their first few clients (ex. referral, specific websites, etc.)

I'm a UI/UX Designer, mobile designer, front-end developer, I can also do some backend in Rails, etc.

Thanks! =)
I've been in many situations where I needed test data to use while developing or validating code. progLipsum (name subject to change) is my answer to making it easy for developers to get the data they need to test with.

Is progLipsum something that you find useful? What changes or additions would you make? I appreciate any feedback, and aim to continue development if this proves to meet the needs of other developers.

Also, I developed this as a solo entry for Rails Rumble 2012 - if you like it I would appreciate a vote at http://railsrumble.com/entries/355-proglipsum ;) Feedback is far more important though...
> take only 1% of 1% of 1%

1. Why? I mean, I get that it's a very small fraction, but if you're considering a scenario where you only get a very small fraction of the market, why should that very small fraction be more plausible than, say, 1% of that?

2. OK, so the population of the world is about 7 billion, and 1% of 1% of 1% of that is 7,000. That's not actually so very enormous, especially as you're not going to get a lot of recurring business. (Unless you're envisaging that people pay on a subscription basis for the continued use of the locks on their home, in which case I think 0% of 0% of 0% is a better guess for the likely market penetration.)

I have been working on this for fun in my spare time. Probably not the best fit for what you are doing as my primary focus (so far) has been controlling IR-controlled devices via a web interface. It is still a bit of a hack but it works well for controlling my TV, stereo, xbmc, x10 lights from anything with a browser. I have been hosting it on a raspi and it is pretty fun to play with (turning off my fiance's 'say yes to the dress' from the bathroom).
Good luck with your project.
The issue isn't Facebook's controls, it's user behavior, and there's little anyone can do about it.

I don't use Facebook because of this. There's not much the company can do to prevent people from making things public about you that you'd rather keep among friends. How is Facebook to know the implications of you being at one party vs another? Sharing is sharing. Just because you keep your profile locked down doesn't matter when someone else can share whatever they like with whomever they like. I understand not having a profile doesn't completely prevent this, but it helps make it a lot less public. Nobody will receive a notification linked to my profile that I was tagged in a photo because there's no profile to associate. We're past the point of being able to prevent this entirely, but I'm not going to make it any easier.
They don't read books at HBS. Instead students go through about 600 cases over the course of two years. The cases are interesting but the bulk of the learning comes from how the professors dissect the case and facilitate the classroom in debating the various positions. Of course you could order all the cases from HBS but that's pretty pricey and you won't get the teaching notes.

Thanks for the response, and everyone else who contributed.

The idea of copying-GC compaction was something I hadn't considered - that's a good point.

For a Game though, I still can't see that being better than a decently tuned manual setup. Not even an expert system; for the android game I'm working on currently it's been quite easy for me to batch up allocations sensibly into regions, fixed-sized pools, and some stack allocators, and I'm far from an expert. A lot can be moved into normal stack allocations (i.e. local buffers or alloca() if necessary) and then you avoid most of the slowdown. My malloc() implementation is pretty naive currently (simple linked list) but it's called so rarely and in such predictable patterns that it's not worth me improving anymore (though there are plenty of ways that I could).

I would be interested to see how well a really good JIT doing escape analysis would perform, I suspect there could be a lot of gains there.
Practical Advice for Raising Early Stage Venture Capital
I built a camera like that out of wood a couple years ago. It uses gears on the inside to pull a regular roll of film through and expose it through a narrow vertical slit as you rotate the whole camera on its center axis. It's sort of a broad-stroke photo.
http://nnife.com/d/?dimension=33

Here are a few shots that turned out decently: http://nnife.com/p/?dimension=20 These are just film scans. You can by the light bars see on the photos that it was very hard to rotate the camera at a constant rate.

You can also see that as I went with/against the traffic, cars were elongated or shortened. Really interesting phenomenon. I was working on this with a painting teacher at the school I go to, whose fascination with unconventional forms of photography got me interested as well. Unfortunately I was a woodworking noob when I made it so its success rate was too low for me to keep using it and I never took many more photos than that.

If I ever get around to building a better version I want to try an idea he had: mount the camera in a spot and expose it over the same piece of film at three different times of day using red, green, and blue filters. That would add another level to emphasizing time in a photograph.

The teacher I was working with is named Nicholas Evans-Cato. The experiment started off as just one to make a film panoramic camera. You can see why he'd be interested in that if you look at his work. http://www.georgebillis.com/artists/nicholas_evansCato.html

I'm sure it's been done before, but it was a really fun experiment. Changed the way I think a little bit.
That's a bit of a problem with the internet , it's very difficult not to trip over spoilers.

The option of being able to donate one's commission is a nice USP. Many people would feel 'guilty' sending links for which they are monetarily compensated. So being able to send a referral link saying, "hey check out xyz, it's cool. And if you buy a portion of the proceeds is donated to charity". This removes what would be seen as a biased ulterior motive...
I would say a "shared secret" is not "security through obscurity." After all, the only cryptographic system you can mathematically prove to be unbreakable in theory given any advances in mathematics or physics and unlimited resources, involves the two parties sitting down together and sharing a secret beforehand. (OTP). Everything else is less secure, not more secure.

Security through obscurity would be if the "shared secret" was something about the design of the security mechanisms, and not about the shared key. (For example, if firefighters knew that pulling up on a doorknob quickly three times caused it to open. That's not a secure key, people would have already guessed it whenever they did so and doors just opened.)
A Critic's Manifesto: The Intersection of Expertise and Taste
I'm not saying that Felix didn't intentionally deploy his chute early to preserve that last record but here are a few points to consider:

Right before Felix deployed his chute he complained that he had poor visibility because his visor had fogged up. He had been having trouble with the heating element on his visor before the he made the jump as well. So it is possible he made the decision to deploy for safety reasons if he wasn't able to accurately gauge his altitude due to poor visibility.

Lastly, in the Project Excelsior jump Kittinger used a drogue to slow and stabilize his descent. This is at odds with what Felix was trying to accomplish which was to break the sound barrier and achieve the fastest free fall record. So, the difference in speeds between Kittinger and Felix may have been enough to prevent Felix from also beating the longest free fall record.

Are these so-called "visibility tags" really crypto-capabilities?

note two years ago I found that LinkedIn group were choked off by useless spam announcements and discussions. Things are much better now in some groups.

Spam is still a problem in many LinkedIn groups, but it's the responsibility of the group administrators to keep it under control. Many groups are dead but many are worthwhile.

LinkedIn lets you join up to 50 groups and you should take advantage of this fully. Of course, you want to join the best 50 groups so look for good groups and unsubscribe from bad groups.

> I don't see how mathematical contributions hundreds of years ago have any relevance to the modern world.

Math is timeless unless it's mistaken.

...there’s an alternative math metaphor we might use: calculus. The calculus metaphor asks whether and how we can figure out exactly what’s going to happen. Take NASA and the Apollo missions, for instance. You have to figure out where the moon is going to be, exactly. You have to plan whether a rocket has enough fuel to reach it. And so on. The point is that no one would want to ride in a statistically, probabilistically-informed spaceship.

http://blakemasters.tumblr.com/post/20400301508/cs183class1

The origins of calculus can be traced to ancient times. Moon rockets. Let that sink in.

Elon Musk and anyone else who pushes that envelope must stand on the shoulders of the giants who came before him, including Arabic mathematicians (indirectly).

What about mathematics that are thousands of years old, i.e. geometry from the ancient Greeks? Buildings with architecture based on the golden ratio[1] are aesthetically very pleasing, e.g. Georgian architecture[2]. Far nicer and better proportioned than most of the shit that's hastily thrown up all over the world today.

Every time you fire up your computer, you're taking advantage of boolean algebra[3], first laid down in the 1850s by George Boole, which is critical to modern computer science.

Mathematical contributions from hundreds of years ago has an incredible amount of relevance to the modern world, in countless different ways.

I wish I knew more about the history of mathematics to counter you more forcefully.

I would also urge you to read this book:
http://www.amazon.co.uk/Civilization-Killer-Apps-Western-Pow...

It shows how that in the 15th century, Europe was a shithole backwater, plagued by diseases and wars, and other civilisations like the Chinese and Arabic ones were far more advanced. By various accidents of history, the western world dominated the rest over the next 500 years. Some would argue that the wests' power is currently on the wane, and China is rising again.

Whilst I find this whole privacy setting issue unpleasant and frustrating, I am continually amazed that people would be Facebook friends with parents and relatives - from whom they would prefer to keep things hidden.

I would not let my parents sit in the room whilst I chatted with friends, or listen in on phone calls. I would not let them go through the photos on my phone, nor those of me on the phones of friends.

I think the point of a social network is to stay connected to people with whom you are comfortable being yourself.

I feel incredibly sorry for the people in question though.

But... the fact that the servers honored the code being used multiple times _is_ permission. You can't assume that this wasn't EA's intent, (although it's almost certain it wasn't). Ultimately, the onus is on EA to make their system work right.

I'm not arguing that people who abused the code weren't doing something wrong, but it is not cut-and-dried. However, I definitely disagree with the idea that they were "stealing".

I think a better analogy is when a business accidentally advertises a product at the wrong price. They are required by law to honor the advertisement even if it was a mistake. This is much closer to the situation with EA than the idea that they "left their front door unlocked", etc. Regardless of other circumstances, the transaction was legal, and I think the law might well require EA to honor it... but I don't know the details.

Another analogy would be issuing a coupon and forgetting to include "limit 1 per customer", or even having a salesperson giving out free product, who misunderstands and doesn't limit the product to one per customer.

Would customers in those cases be considered "stealing" if they took advantaqe of these situations? I don't see how that can be argued. Could they be accused of being greedy? Definitely, but as much as people might wish otherwise, being greedy isn't against the law.

FWIW, I didn't use this code, and wouldn't have exploited it even if I had. I have too much great stuff already from GOG, Steam and Humble Bundle, etc... that I don't have time to play it all. I have no need nor interest in exploiting anyone in this way.

You can just make a video, and select a column of pixels. Then place the different columns (color-wise) you get from each frame next to each other. The resulting image will have the same width as the number of frames you used and it will probably have a lot of artefacts considering the quality of today's (home) video technology. But it is essentially the same.

Just what came to my mind just now.
I'm also sceptical. It's hard enough to get consumers to understand and bother with the affiliate model when they could earn pounds (http://www.quidco.com/), let alone pennies (refer.ly). I suspect they'll pivot (either towards Shopcade or towards Skimlinks) within 12 months.

I remember the first time I got tagged in a picture by a friend on Facebook. I deactivated my account immediately because it felt really unsettling that people were "checking me in and tagging" me at places I didn't even know I was being tracked at. Alas, given enough peer pressure in my circle I reactivated it simply because it was easier "to invite all friends at once to parties and other events", and I was missing out on most of then unknowingly without even getting an invite. One might say I need better friends, but I sympathize that when you have 25 people to invite or more, that you are going to miss people. The tagging still unnerves me.

I assume partisan is being used in place of 'heavily biased'. I can see it is a reasonable substitution in most cases.

The 'Pure Science' people (similar grouping to the militant atheists) are, like it or not, pretty dismissive of any non scientific opinions and beliefs. This makes many religious people take a very defensive (aggressively so) position on many matters.

This is simply a different version of the "two parties facing each other and calling each other dumb" political system.
