I used Unison + cron for years, but recently I had to replace a machine, and discovered to my horror that my synced directory has grown beyond the size that Unison is capable of doing an initial synchronization of, EVEN if I precopy all the data. So AeroFS looks like it might be a killer app for me.

Does not it look amazing how times have changed? Notepads have been replaced with personal Digital Assistants. Telephones have been replaced by cell phones.
OK, Mr. Goetz is correct for the most part on all counts. And I don't understand enough about the software patents arguments to really comment one way or the other. But what I do know is that the bottom line, and what ultimately turns me against software patents (and drug patents as well) is that this is really all about money.

How does humanity as a whole benefit from a patent holder demanding compensation for the use of their "software invention" when it's duplicated, unknowingly, by an independent hacker working in his basement on a pet project following the rapid uptake of their project by the greater software community? What if the hacker gave the software away for free? How does the original patent holder get compensated?

Or what happens when implementations of useful, but somewhat obvious technical solutions to problems are patented? Like linked-lists, for example? Or a compression algorithm? etc. etc.?

IMHO, just because someone implements something in software first, doesn't necessarily give them the right to own that implementation for some unreasonable amount of time.

There must be a better way?
I was all ready to jump in -- under my real name, even -- until they started shitcanning (entire) user accounts. I am already too dependent upon my pre-existing Google account/services; I can't afford the risk.

A bit of irony in that.
Looks good. Although is [] associative in Python (haven't coded in Python in about 12 years)? The append method makes me think it isn't. If it's not then it goes from: O(n) where n is the length of the string to O(mn) where m is the length of the alphabet -- although m is small, so maybe not that bad of a deal, you could almost treat it is a constant factor, since it will be dwarfed by n.

I do like the early exit.
And there's also isshort.com, which will output publisher-provided short URLs (flic.kr, n.pr, etc)
Actually copy on write would help you 100% here :-) you just need to take the abstraction a level up. That is mutations to your list would create a new list. The original thread continues reading the stale copy. Therefore reducing consistency issues. You will see that is how (in Java) ConcurrentHashMap works for example. There’s no magic bullet ever in coding, but CoW can make life a lot easier, and certainly that is my experience. So I’m just encouraging folk to think about adding it to their toolkit. Thanks for the comments though it’s interesting to talk about the use cases.
CVS doesn't store revisions locally so it takes a fraction of the space.
I remember work for pie has been featured here before, though they have added more details now which is great. Though I believe http://www.gitalytics.com/ gives a more detailed analysis based just on github contributions.
The WHATWG strikes me as exactly what a standards org is supposed to be: enough vendors to form an industry consensus get together and agree to cooperate on certain things for their collective benefit. Or is that the point you were making?
Interesting first-person account of making core memory
While they'll probably continue to acquire customers indefinitely for the near future, the question remains whether, once they've captured adequate market share/some sort of saturation point, they can really improve their customer retention through much better targeted deals, and perhaps, some sort of user engagement on their site. In theory, at some point when they stop acquiring customers, if they can have good user engagement and therefore retention, they'll cut out a large chunk of their costs (customer acquisition marketing) and still have their user base that draws revenue. Whether Groupon can pull this off, with ever growing competition, is the question on everyone's mind.
I said the greatest marginal benefit was from debugging. I didn't say it was the only one. :)
All I'm saying is that it could be sufficient defence against a DMCA. He should IMO edit the page to state the license.

>if the general term fits the case//

The general term "completely free" means that I'm able to do absolutely anything with it without paying.
It's been said before, but it's worth repeating. Conferences are a high risk business operation. For every SXSW, there's a thousand "Learn to Buy Real Estate with No Money Down" conferences at the Ramada Inn next to the airport. Paypal is not in the business of assuming your risk. They are in the business of processing payments while mitigating their own.
Yeah, to be honest. Branding the product in comparison to Chatroulette is just a bad idea. When Chatroulette first came out, it seemed like a really cool concept. The ability to travel the world from your computer and meet people face to face seemed promising.

Sadly, the inability to moderate the system has left the vast population disenchanted with the service. Branding yourself with Chatroulette will only bring along that baggage and negative opinion.
That's a good point. I guess you can check that the password hasn't changed
The pyramid in this case is that the people getting acquisition exits are becoming angels. Not really that different from your example of Sun/Oracle/Yahoo profitability help drive the tech bubble.
Cheap, good, pick one. But there's no shortage in numbers, anyone who picks through CVs for their company will tell you that.

Actually a history on a state machine give’s you undo functionality a fairly common pattern, no? You have a stack of states instead of a single state. Trouble is though inter-related states isn’t it :-) things can get messy if you don’t have atomic states.

Actually someone else just pointed me in the direction of Event Sourcing - every pattern has a name somewhere - http://martinfowler.com/eaaDev/EventSourcing.html
Paypal classes events as high-risk transactions (as they require people to pay upfront often far in advance of the event) so you're at much more risk of being suspended if you breach their risk thresholds.

Imagine if you're a fraudster, you've knocked up a fake event and you've sold $10k-$20k in tickets, you could withdraw the money and disappear before the date of the event. Now Paypal are on the hook for the money, when they get creditcard charge-backs it comes out of Paypal's account and not the fraudsters.

Does anyone consider it reasonable that Paypal take this risk ? - the reason for the 90 day limit is that's the length of time most consumers have to request a credit card chargeback. Paypal is simply protecting themselves.

If you're engaged in high-risk transactions you're much better off going with a specialist provider (i.e Amiando or Eventbrite in this case) as they have risk fraud models designed to handle the specific risk factors.
Just thinking out loud: does doing copy on write result in less filesystem fragmentation (assuming the data is not held in RAM)?
Devil's advocate: there are some conclusions to be made from someone's level of personal grooming, etc. Grooming = sign of mindfulness. If you're willing to make that - token, mind you - investment, folks get a message that you are interested in others' opinion, and that your wonderful solution was built with someone's specific problem in mind.

The general underlying point is that there is a deluge of ideas, features and suggestions, and folks put up filters like the above to sort them out. The unfortunate flipside is that some filters are more arbitrary - like the prestigious school prejudice.
Thanks very much for this link. My reading of the article is that communications and social interaction will be the main use for computing devices, and that market will grow significantly. It might be that the desktop PC is still sold in large quantities for those that need it.
Can you point to a few examples?
That seems a good deal less scientific than the numerous studies that have strongly suggested the opposite.
I see this as investors playing hot potatoes. Smart VCs hyping up their own companies and selling it to less knowledgeable investors. Last year, Roxio made 5 million, pretty good for a game but worth 1.2b? Tech companies get ridiculously high profit (most cases just # of users) to valuation ratio because of their future potential. Do y'all really think Angry Birds will still be a household name in 3 years?

Regarding international expansion to China. Most people in China are not gonna pay more than the equivalent of $3 for a stuffed animal. The ones that people are buying would be counterfeited.
I am currently porting a Ruby application over to JRuby, and use tmux (although I am pretty sure screen would behave the same). Let's say you have two rubies installed, ree and jruby. You start out using ree, and are using screen/tmux, and have two screens open.

If you switch to JRuby in the first screen, then switch to the second, the changes don't propagate. e.g.:

(first screen)

$ rvm list

rvm rubies

=> jruby-1.6.3 [ darwin-i386-java ]
ree-1.8.7.2001.03 [ x86_64]

(second screen)

$ rvm list

rvm rubies

jruby-1.6.3 [ darwin-i386-java ]
=> ree-1.8.7.2001.03 [ x86_64]

It's not a big deal -- you just have to make sure you do the right thing -- but it is unexpected and has burned me a couple of times. It looks like rbenv won't suffer from this problem.
Don't fall in to the trap of thinking this is a purely technological problem. What really stops a grounded teenager from still going out with friends instead of coming home after school? Nothing physical, nothing technological. This is human stuff, not computer stuff.

(No, seriously, take a moment to ask yourself that question and ponder the answer. It's actually a rich, interesting question.)

The real point here would be to raise the threshold of temptation high enough that it can be resisted, rather than strict technological restriction.
I'm in the US, but find myself in the UK for some time every few months. While I'm not opposed to donations, I'd also love to see a tourist/business traveler guide covering establishments that were affected and would benefit from additional traffic.

Also, do they need to go public? YC has a handful of partners afaik and they had a bunch of exits in past couple of years.

What will YC gain from an IPO?
"you need one of your alumni companies each year to achieve an exit in the $25 million range"

In the case of a company like WUFOO, YC & PG did a follow on round of ~$100k bringing YC's total equity stake to say 10% and with an exit of $35m YC made off with $3.5.

The point being the initial $15k investment is to gain access to great companies at the beginning so that investors can make follow on rounds in the best companies in the class. This is where the real money is made with incubators and how this differs from the privies bubble where VC's would invest $10m in an idea for a company with zero revenue. Looks like capital efficiency to me...
Hey, I like the look of gitalytics! I have never before seen a site that dug into my history deep enough to highlight that one tiny documentation patch I made to a comparatively high-profile project.

In a way it outshines my many commits to my own unloved projects; most analyzers don't pick that up.
> That's what the European Union is about.

That's what some people would like the EU to be about. Fortunately, there is a healthy diversity in people's views on that issue just as with many other issues. Thus, in practice, we have always had European integration on several different levels depending on the individual needs of the nations involved and their collective benefit from co-operation.

Today, being in the EU is not the same as using the Euro. Though the Lisbon Treaty blurred a lot of lines, we historically had the European Courts of Justice rather separate from the European Union as well. There is a lot more historical detail on Wikipedia's page on the EU if you're interested.

If anyone thinks Europe will still look the same in five years, I think they are probably missing something, given the obvious differences in financial power between say Germany and Greece today and the obvious negative effects it is having on the better off nations. Who knows the consequences at this stage? Maybe the result will be closer integration where the financial policies of the weaker nations are restricted by the stronger nations who support them. Maybe Europe will fracture as an economic community but perhaps continue as a legal, diplomatic, free trade, and/or military one. It is clear that on matters like the privacy issue at hand, there is a lot of common ground on the basic principles regardless of economics, so I suspect that side of things will be maintained.
I emailed my nuclear engineer friend about thorium reactors, if they are being used, etc. This was his response:

"Metal reactors are better, but are different. Eventually they will be used in conjunction with light water reactors, because they use spent LWR fuel as new fuel. The only reason they arent around is that the NRC doesnt have the knowledge/expertise to approve them. Also the usgov is super anal about breeder reactors since technically you can make weapons grade fuel with them, even though its be a nightmare seperating Pu form the rest of the fuel."

You're not the only one, it's been noticed before by a bunch of SFF writers here: http://nielsenhayden.com/makinglight/archives/012933.html

Includes suggestions to file DCMA takedowns, and generally how much amazon doesn't care.

I wonder, in idle speculation, if a three strikes law would remove their internet connection for three instances of trying to sell a copyrighted work where they don't have a license to distribute it.
I think the problem you're getting at (and I agree with you) is that obvious things are patented all the damn time, and it seems to be especially a problem in software. We need better trained examiners, and it ought to be a high bar.

I don't have any issues with it being "all about money." I do have issues with someone getting a patent on a method that would occur to anyone trying to solve a similar problem.
I disagree. There is no shortage of people who think that they can program but, from experience, there is a huge shortage of people who actually know what they're doing.
Can someone send me an invite please? I'd like to try this...

The biggest problem I have with centralized servers in the first place is that I don't trust my data with them. If it was decentralized and open source, that's an app I could see myself using.

Closed source = no good for privacy.
Another thing he failed to mention: expandability. I got so sick of all these different external hard drives, each with their own power brick and USB terminator (micro? mini? heck knows). Bought a Mac Pro and put them all on the internal drive bays - now everything lives in a single box and runs off a single power supply. I also put a blu-ray burner in the 2nd optical bay - another external box saved.

The same is true of other outboard hardware - for example, I use a UAD-2 card for music production. Sure they have a FireWire version for laptop/iMac owners, but in place of another box with another power brick taking up another (often scarce) port, I got a tiny little PCI card that goes in the box and is never seen or heard from again.

I understand not everyone needs tons of storage, or dedicated audio/video hardware, but if you do, desktop can't be beat.
Sometimes It’s Harder to Preach What I Practice
Thanks for your response. Here are a few issues I would raise though:

"It would be incorrect to conclude from these results that treatment makes no difference or is not worth pursuing"

They are defining treatment as either medication or therapy, not just medication.

"medication management-may only make a persistent long term difference if it is continued with the same intensity as during the MTA's initial 14 month period"

OK, but this is completely speculative. The researchers don't even give any reason to believe that this would be true, let alone point to any evidence.

"It could be that ADHD symptoms are positively correlated with psychosis."

The research states that all of the kids who developed psychosis were on ADHD meds, the group that was diagnosed with ADHD but was not medicated did not develop any psychosis at all.

"there is no indication that stimulant medication is wholly poor performing and that early studies indicating efficacy were flawed."

There were no early long-term studies indicating efficacy though, these are the only studies that were ever done.

Whatever happened to "caveat emptor"? If you're attending a real estate conference at a Ramada Inn, you weren't defrauded - you're just an idiot.
"it’s hard to imagine that today’s tepid consumer and business markets have room to absorb all of the products and services offered by the hundreds of new startups that the incubators are now churning out each year."

I think he's overlooking the element of disruption here. While it's true that certain markets will need to expand to fit these new companies, many of these startups are entering markets with the hopes of exploiting inefficiencies in more traditional companies, or simply doing things better.
Ultimately the economics of a desktop just work better.

You can build an i5-2500k, 8gb ram, 1 tb hdd, gaming caliber video card machine for $600.

Rather than buying a $2500 macbook pro, you can get a gaming desktop with a 30" display, and a macbook air/ultraportable and really come out way on top.

Of course there's the question of juggling 2 environments if you have complex needs, but most people would be fine with a simple dropbox setup or something.
Is that so? I don't recall saying those things.

I did say an open space for them to get the energy out, so that when they return they are more able to focus on 'accomplishing things'. Whatever it is kids need to accomplish other growing up.

Yes, I'm biased (not prejudiced). Due my experience, which I stated clearly.

Taking a set of traits that don't work in modern society and calling it a DISORDER is the only intellectual dishonesty here. Prescribing meds for a behavioral traits that people don't approve of is selfish, controlling, and a true detriment to those kids.

That ADHD (which I did not deny exists, I stated it did, and that I believed it's genetic basis) is treatable by Ritalin/Adderall I don't deny.

I just happen to know the long-term effects are detrimental. Studies happen to back me up.

Studies also show behavioral therapy is as good as medication. It's far better for kids as they get to learn about life without being on drugs. They learn real life skills rather than brute force concentration through drugs.

"I was not myself" is true. I was drugged with something that crams neuro-chemicals into my brain making me into something other than I wanted to be.

There is no true self (especially mystical). There was a natural me and a me on Ritalin (which was very different). I would have preferred to learn the life skills I needed and haven't learned until recently. I had the experience for a reason and often I believe it is to let people know about it and possibly protect other kids from what I experienced.

Sincerely,

Then PayPal should provide a way to pre-mitigate the risk. For instance, they could require a bond before ticket sales start. Rather than screwing legitimate users, there are other ways to solve this problem.

The short is that PayPal just doesn't care about small users. If they did, these problems would be solved.
It was 1995 and Kevin O’Connor was sitting in a basement in suburban Atlanta with Dwight Merriman trying to figure out how to build a business on this new thing called the internet.

“We thought maybe car sales would be big. We figured porn would be huge, but we didn’t want to get into that.” says Mr. O’Connor, who along with Dwight Merriman and Kevin Ryan, would go on to build the DoubleClick, Silicon Alley’s biggest exit and the engine behind Google’s profits. "Eventually we settled on ad sales."

What If these guys had decided to work on porn...
Paypal is often the only option. Nobody wants to use paypal, they're forced to because paypal is all they can afford.

Summer 2011 YC company seeks CoffeeScript drinking frontend engineer
We're an un-announced YC company that's dragging online advertising into a better and brighter future. The company is profitable, growing fast, and solving fun problems along the way. Our current fun problem is recruiting, we need a sophisticated frontend engineer to help us get faster. Read on for the tech world equivalent of a personal ad:

If you love coming up with ways to make users smile and have the technical chops to put your ideas into action, we want to talk to you. You'll be most effective if you're familiar with and excited about the various levels of frontend tech, including client scripting (we use CoffeeScript) and the magic that gets things in front of users (we use Rails/Node.js). Design talent and good ideas about big data visualization (d3 is fantastic) are especially cool.

Our stack is modern, shiny, and backed by a MongoDB/Redis combo handling several million events per day. We do automated deployment because people should see features while they still smell nice.

Send us an email (syncretic.sausage@gmail.com) and let us know what you think. SF/Bay Area is preferred, but not a requirement.

Odds and ends: we realize the last 37 Hacker News job postings have been for frontend engineers. You can't go wrong with any of those companies, honestly, but we think there are enough amazing people on HN to scoop one up for ourselves. If you're a Hacker News reader and can think of someone who should have this job, let us and them know. We'll give you both an iPad when we hire them.
