Why not use Unison? It only does pairwise synchronization, but is Free software and extremely mature.

Really simple, an easy way of buying and selling them on the fly at almost any time and with minimal to no hassle worldwide. Bitcoin ATMs would be a great way of doing this but i'm thinking fo something as easy as walking into a currency exchange anywhere or something like it and buying some euros for dollars.

Digitally, make buying them as easy as using a credit card (prepaid or not) online to buy an ebook
Why MD5 the email addresses? If you just need a unique id for a user, why not use a GUID or something that isn't traceable from public information?
The article mentions that Atlantic Station sits on a large parking deck, but doesn't explore how its 7,200 parking spaces can make an otherwise small outdoor mall very busy at popular times. Cars remove you from your immediate surroundings, but they also enable you to temporarily be part of a community physically distant from where you live.

The answer to why Atlantans drive so much is not that they are lazy, but that they have somewhere else to be. You can lament that walking is good exercise, or you can appreciate the ability to raise a family in a house with a backyard while having a reasonable commute to a Fortune 500 company's world headquarters, a startup community, or a global research university.

Walking everywhere is nice as long as you know exactly where you want to live, you don't care about space, and can afford high rent.
A large part of it is crime and/or race. The modern subdivision - full of meandering streets and poor connectivity to nearby arterials - is deliberate. It creates the gated neighborhood effect without the need to put up any unsightly walls or gates, and in effect keeps its residents separated from the world outside.

The world outside presumably filled with undesirables.

The lack of connectivity discourages through traffic (i.e., undesirables), and meandering streets that run every which way helps artificially draw out the walking distance between any two points, further hobbling any desire or ability for people who walk/take transit to visit (i.e., undesirables).

Suburbs weren't always like this, we had walkable suburbs a long time ago, and in some places we have them again. But the most typical archetype of a suburban neighborhood is an exercise in extremely class-conscious design.

Despite the revitalization of urban cores across the US, the mentality that drove the construction of these suburbs still remains. The thing that jumps into my mind is the furor over Seattle's extension of light rail into Bellevue - a high-income suburb. All of the opposition boiled down to "but the undesirables!".

Until we shake the whole "urban = poor" thing, we'll continue to architect our suburbs in this way.
Can someone more familiar with $BITC explain how Bitcoins can be portioned? I get that each bitcoin is a unique number - how can 0.4 of a number belong to someone and the other 0.6 of that number belong to someone else?

Thank you for sharing! Is there a quick way to identify what sites are running Python? (view source, etc.)
How would you like it improved? I rather like it as it is--I've completely stopped using Adobe Reader, in fact--but I'm curious to know what you think is missing.
It depends. There is a certain allure to working with a shiny new technology. It's sort of like an adventure, because not many have paved a strong path forward yet. But not everyone likes an adventure. Sometimes there will be huge roadblocks that don't have obvious solutions; especially for the beginner.

On the other hand, the scientific computing crowd for Python/NumPy is well established and there will be plenty of people who have probably come across any problem that you will see. There is already an established ecosystem of tools that you'll be able to draw from, and it's likely that many of them have been well tested and are reliable.

The decision is really up to you. Do you have the time and desire to go on adventure? If so, maybe Julia would be a nice pick. Are you short on time or weary of adventure? Then maybe Python/NumPy would be a better pick.
Ask HN: What's on your christmas wishlist?
As Christmas approaches so too do the questions of what you would like. To pre-empt things a little I was curious to discover what the fellow hackers of HN would be putting on their wish lists this year? In particular are there are tech or development related presents you have your eye on? Hopefully this will collate some ideas from like minded folk who are pressured to come up with ideas for gifts this festive season.

Given the amount I've spent on technical reference books this year I will be hoping for a Safari Books Online subscriptions.

Agreed. Honestly, I wasn't even familiar with the idea that someone would even consider adding someone on LinkedIn who they hadn't already met in person. LinkedIn is just a useful addition to that in person meeting.

The hyperbolic intro didn't really help:

> If anyone in Silicon Valley knows the value of secure access and keeping information safe, it’s him.

I can think of, I don't know, 30 people at the top of my head that I would rather be listening to. If you caught me in a drunken stupor I could probably still give you 10-15 of them.

That said, there's nothing really wrong with the article, but it's also pretty basic. Putting stuff behind VPN and installing antivirus can help you, but it's not anywhere near enough if you're actually exposed.
Thank you for the patient post.

People will probably despise me for this, but why don't we have compulsory military duty in the U.S. like other countries?

It would give people some discipline. It would discourage us from acting arrogant, "lol! we should bomb them!" It would give people some skills. If it was equally applied, no one would have any disadvantage. It would make people feel much more secure, without delegating their security to others.

The real scourge is that in order to be economically competitive, we must all hyper-specialize and become experts in a single, narrow area. We can no longer lucidly judge others b/c we have less in common with one another.

A work buddy said in the 1950s in the U.S., teenagers would hang out with the police. He distinctly remembers hanging out in a police car, smoking marijuana, while the cops chided him because he said he couldn't afford real tobacco to smoke. I want to get back to that world. I want to provoke other nations less, so we're no longer a target of terrorism. I want us to get back to the business of making our lives leisurely through technology, rather than more awesome. "More awesome" means were doing more with the same energy as we exerted in the industrial revolution. I'd much rather see us getting less done with less energy.
I wish people would move beyond 1984 and quote more Foucault's Discipline & Punishment [1]. There is a much deeper-rooted problem in society than mass surveillance or militarization of police. It's the question of why we all let this happen without any resistance. We accept and welcome our controllers. Foucault wrote about the effects of prisoner mindset in society in the 1960-70s. Our subjugation and tolerance to authoritarianism is very widespread and not limited to just police.

We're not just afraid to be anti-authoritative, we're institutionalized since our birth in schools and the concept of control is in embedded in every aspect of life (such as in language found in politics, school work, or newspapers).

Mass-surveillance is just a more direct implementation of "panopticon" [2] applied to everyday life, existing at all times. Having committed a crime is no longer the requirement to be imprisoned, whether physically or mentally.

If I am reading it right, the developer of tip4commit will never pay out the full balance since they will only ever pay out 1% of the remaining balance. It almost sounds of this site is just a clever way for their developer to increase their position in bitcoin speculation.
Seems kind if weird that Bitcoin (actually bitcoind) itself would be dependent on a google-developed database solution that isn't open source, and not only that, has non-determinate behavior, depending on the host system..
>Why do most people fail to walk even the 10,000 daily steps needed to stay healthy?

Where does that figure come from? A lazy guestimate of 1m/stride puts that at 10km/day. That's 2 hours of walking a day. Who the hell spends 2 hours a day walking?
> I would suggest that what we need is some sort of ready reserve system where everybody is trained at reaching 18 on how to safely use most all common forms of police and military gear. I'd further suggest that local police departments be required to have a certain percentage of their patrols as civilian ride-alongs.

The military reserves are certainly an option, but having a mandatory training+service aspect certainly seems ... interesting. Frightening, in a way, but it seems to work for Switzerland.

Bitcoin transactions have a fundamental unit which is much smaller than a whole bitcoin. Actually it's 1/100,000,000 XBT! These tiny units are called satoshis, after the creator of the bitcoin protocol.
I used to religiously apply that view, nobody is in the driving seat, chaos reigns, conspiracy theorists are looking to replace their father, etc etc. These days I try to take more of a balanced perspective.

There are many examples of covert malevolent acts in the halls of power throughout history, there was a list of confessed false flag operations on here just the other day. Look into any book about the history of military intelligence and you will find all sorts of nasty adventures. Then there's COINTELPRO, MKULTRA, the FBIs attempt to undermine the civil rights movement, it goes on and on. What would be truly irrational would be to believe that this stuff doesn't happen in the present.

So now I try to evaluate each "conspiracy theory" on its own terms, lest I blind myself to the one that turns out to be real.

(Note: I still don't actually believe in any specific tinfoilery. I just try to evaluate it honestly. Almost all of it, I still dismiss immediately. Most of the really juicy stuff is right there in the history books anyway.)

My more ideal city would have higher density housing but with small private yards, if only decks that seem like yards, something like this: http://www.dwell.com/house-tours/article/mountain-dwellings-...

Maybe I'm blind, but is there any way to browse a list of listings? Also just a heads up, but the background image on the landing page took about 8 seconds to load on my machine. It's beautiful, but you might want to either re-encode it with more lossy compression, or just nix it altogether.
Alice was a fantastic, highly underrated game.

Sadly nothing else with his name attached (Grimm, the Alice sequel, Scrapland, Bad Day LA, etc) has been nearly as good. Not that they are bad (with the exception of Bad Day LA which is terrible), but they are just sorta okayish, whereas the original Alice was fantastic.
How does it make any sense to multiple the date by the sign of the score? It's true that it only matters when the score is negative, and so it doesn't really affect much in practice, but the code is clearly a typo.

Ok... that one is crazy.

Obey the cop and get suspended... or obey the teacher and go to jail.

Just leaving these kids in no-win situations. SOMEONE has to be willing to listen and hear the kids out.

Either the cop has to hear them out, and then say "OK, well I'll just keep an eye on you until your teacher comes."

Or the teacher has to hear them out, and then say "Well, OK, it was my fault for telling you guys to stand there so I'm not going to suspend anyone this time."

But you can't put kids in a situation like that and then say... "It's YOUR fault!"

That's insanity. This wasn't ANY of these kids' fault.
I don't know where the 10,000 daily steps figure comes from, but moving around more than two hours daily seems like a fairly reasonable thing to do in order to remain healthy.

Or maybe run for 45 minutes, or walk to work, or go swimming or do a ton of other physical activities I am not going to bother listing.

Personally I ride mountain bikes in every way possible, and time permitting also as often as possible.
Does TechStars Really Have a 90% Success Rate?
I like TechStars, but are their published statistics accurate? Please help me figure it out.

I looked at stats available on: techstars.com/companies/stats/ and saw they have a success rate (Active + Acquired companies) of over 90%, but I only see 75%. Here's why.

The first thing I did is calculate without their last 10 cohorts. The reason is these cohorts graduated less than 1 year ago and haven't had time to succeed or fail yet. Without the last 10 cohorts (111 of their 291 startups) the success rate falls to 85% when they are removed. (Or down to 80% is you are more realistic and remove any startups younger than 2 years, but I went conservative.) I'm not changing their definition of success as being survival rate, rather than some other metric.

The second thing I did was look at all startups marked Active. WIthout a way to judge if they are Active other than what I see online, as a proxy I looked at whether they had posted to a blog, Twitter, or Facebook anytime in the last year. In some cases there was news of them going into the deadpool or a domain for sale, but for the most part they look like Zombies, not officially dead.

It's not a perfect way to judge so please let me know if any of these startups that look inactive are really alive:
J-Squared Media, Application Experts, UsingMiles, HaveMyShift, InvitedHome, ScriptPad, Marginize (the team formed a different company but I'm counting this one as failed), Highlighter, RewardsForce, Wantworthy, Creative Brain Studios, Strohl Medical Technologies, Veri, CloudSnap, Emergent One, Rewind Me, ReplySend, RollSale.

To measure accelerator programs against this 90% standard, I'd want it to be accurate. Again, I like TechStars and I'm posting this to learn. If we measure all accelerators the same way, I'm sure a lot of obscure programs have high success rates as well.

Thanks.

Why do you think LevelDB isn't open source? https://code.google.com/p/leveldb/
There's actually a simple technical way around this. Don't store the paper. Store a file hash and let the user access it via approved channels. Most users here will have legitimate access via their institution, or can easily find the paper via Google. Dedupe on upload and link to approved Elsevier stores. Easy peasey.
Is this something you intend to run longterm as an actual service, or is this just a demo from the hackathon to go along with the github repo? Was the name similarity to Silk Road intentional? When you say "sell anything," are you attempting to lure out the displaced users from that service? If so, I'd strongly advise you reconsider.

Preloading Entire YouTube Video
I don't think it will be a problem to do both.

It doesn't take long to learn Julia well enough to write a Julia package that others will use. For me, that was about 3 weeks @ 10-15 hours a week, and I'm no programmer. It's a small language and it's quite readable. I'd reccomend going through the Julia manual; it doesn't take long and only requires some diligence.

The problem is the lack of packages/libraries and lots of documentation is still missing. That, and the packages that do exist with multiple contributors are still in disagreement about standards and consistency.
Also, here's a short video showing what's possible: http://www.youtube.com/watch?v=SrsHBjzt2E8
There isn't presently a way to browse listings, although it's definitely on the feature list. The original idea for user interaction was the following:

1. User goes to website
2. User creates a listing
3. User shares link to listing on other sites

It wasn't originally intended as a marketplace, but we're thinking about turning it into one. By the way, thanks for the tip regarding the image. Fixing it now.
So I decided to finally fill out my Academia.edu profile recently and found there was no easy way to add papers. You could upload them or "import" them from another website, neither of which I could do due to the ambiguous copyright status of my papers, but you couldn't enter them manually. The most obvious and unambiguous way would be to enter a DOI, and have them query CrossRef for the paper metadata, but there seems to be no way to do that?

So, in a sense, are Academia.edu not encouraging this behaviour (which is frequently copyright-infringing) by making it hard to add references without actively uploading the pdfs themselves?
I see. It was already in production. It's an open question whether the more complex syscall conventions would have held up over time as new features were added. It makes a lot of sense in general to push unnecessary complexity out of the kernel and into userspace, since processes in userspace are allowed to fail. The complexity of the system call interface can be hidden behind a library.

This generalizes to all forms of intelligence: those who are afraid of the feeling of stupidity and ignorance get stuck and don't move past it. I can't count the number of deeply intelligent people I've known who short-circuit their thinking and learning processes due to this fear.

It's not a self-esteem issue; it equally affects those who see themselves as smart, and those who don't. It's an issue of tolerating discomfort and confusion long enough to get to the other side. I'm not sure how exactly one teaches that.
Thanks! Capabilities live up to the design, at least :)
Yes, it's a shame that Mr Marcus didn't discuss how he bought his Bitcoins.

Did he have to play the two-step bank account shuffle like the rest of us?
Any word on when it'll be available outside the US? I thought at launch they said a few weeks... (or at least 'soon').
I somehow read "Earn 4 bitcoins for any commit..." and thought "wow that's really generous", I was like, very wrong haha.

If you discover a conspiracy that you believe, in absence of proof, what can you do with that information? I stopped trying to "figure it all out" once I realized that there was very little I can do as an individual, even if I am right about some conspiracy.
The same way that you can send someone part of a dollar. The atomic unit of USD isn't the dollar, it's the cent (setting aside some financial instruments). Likewise, the atomic unit of BTC isn't a bitcoin, it's a satoshi (1 * 10^-8 bitcoin).

The unique number that you're thinking of isn't the bitcoin itself, it's the proof that that value was yours to spend.
