It is very lame. I take it as a sign that the people behind it would likely have mis-managed things. The failure to keep an eye on things, or find that last push that was needed, is a red flag.
I hate to be mean and kick them when they are down, but quite frankly this might speak to their ability to execute on their final product.

But it was still awesome! I know sooner or later somebody will turn up to say that this 'shouldn't be on hacker news', but I think having an (sometimes offbeat) sense of humor is an important part of being a hacker.

> 5 years go by and you've not touched the subject in any meaningful way so of-course if someone asks you to write a Red-Black Tree or implement Quick Select you probably will not be able to do it from the top of your head.

Well, don't let five years go by without touching the subject. Occasionally practice the things you once learned, integrate them into your larger body of knowledge, and you'll never forget how red-black trees and quickselect work --- even if you never implemented them from scratch.
Well, that is only enough money for a single programmer to work 9-5 for somewhere between 6-12 months.

LocBox, San Francisco. Frontend Engineer, Rails Developer, Data Scientist, Inside Sales Representative. Relocations Welcome, H1B Transfers Welcome.

More at http://www.getlocbox.com/careers and http://www.techcrunch.com/2012/10/31/locbox-series-a/.

I’m CEO at LocBox (http://www.getlocbox.com) and we are looking to work with great folks that share our mission - empowering local businesses to generate sustainable revenue from their best customers. We want to do it with Data, Algorithms and Design in a space that has traditionally lacked all three but is finally turning the corner (and fast).

Most local businesses resort to unsustainable daily deals or boring Email Marketing to acquire and retain customers. We reject that status quo and our hundreds of (paying) customers agree. We’ve also developed a new search/crawl/tech-centric way of acquiring our own customers and disagree with the obsolete feet-on-street Sales model. The company is very small but generating material and predictable revenue; net revenue growth has exploded in the last quarter.

Our tech team is 3 at the moment and the company as a whole is 9 fulltime folks; we're looking to at least triple the tech team size in the next 6 months. The tech stack is standard-issue Rails/HTML/CSS/JavaScript and is deployed on AWS. The product and tech team operates on weekly sprints and there's a decent bit of Halo-playing and beer-drinking at the completion of sprint milestones.

We also just launched with a $5.1M Series A in the press w/ TechCrunch, AllThingsD, GigaOm and VentureBeat.

Ready to talk to us? I'm saumil at getlocbox dot com and at http://www.getlocbox.com/careers.
This is what is laughable. The original IPCC report on global warming predicted an average rate of global mean sea level rise of about 6 cm per decade. The reality? 11 mm or less over the last 2 decades! That's over a factor of 100 miss. Nobody seems to notice how the goal posts on this issue are constantly moving. In the end, yes, there is global warming, but it is not even close to what was predicted in the late 1980s and early 1990s.

If the weather gets hot or there is a drought, environmentalist scientists tell the media that problem is global warming caused by humans. If the weather gets colder, environmentalist scientists tell the media that problem is climate change caused by humans.

That's not what I've been hearing. I see people saying that no individual weather event or localized change can be attributed to global climate change, but that as more total energy is added to the earth system, more chaotic weather events and localized changes can be expected in aggregate (edit: e.g. http://youtu.be/5EaLVOv8cIk?t=1m49s).

They are drawing power from the lightning port (in the FAQ). But you're right - the prototype doesn't show a bulge for that to happen. Nor (as in my other comment) does there seem to be a pass-through port for you to dock or connect a lightning cable.

Regarding the 30FPS, I've seen demos of e-ink running at high refresh rates (don't know what FPS), but was told that the hit on the battery is too high. Hence why the Kindle rarely refreshes.
Uber had better understand that in politics, just because you're right, doesn't mean you win.

As a Bad Person I take it as a given that there is some kind of corruption, more likely soft than hard, in metropolitan taxi regulation. That doesn't mean there aren't legitimate interests represented by those regulators, and those legitimate interests will be the rhetorical focus of the incumbent protection campaign. Uber would do well to appreciate those legitimate interests and get well and truly on the right side of those questions. Uber would also do well to understand the unstated agendas, legimate and otherwise, and strategize for meeting those.

Legitimate questions? IANA taxi expert but I would guess:
- Value of incumbent licenses. In NY cab drivers and companies spend hundred of thousands for medallions. There are whole financing structures built around those values. Protection of those values is probably a key objective of the regulators.

That really is a legitimate problem. For one thing those values support an industry that provides jobs to working class people. For another the city probably views those values as a signal of the stability of its policy environment.

- Stability. Policy makers may well believe that the taxi system works on a number of dimensions, that systems like Uber may not work as well on all those dimensions, and that they may disrupt the system with unknown consequences.

- "Universal service". One of those dimensions may be service availability to low income neighborhoods. Cabs are supposed to take fares anywhere. Regulators may fear that poor people may not have iPhones to play in Uber, and that drivers would discriminate against some neighborhoods if the poor people did. It would not surprise me that the tacit model behind the cabs is "you take the high fare business traffic to the airports, but also the lower revenue low income traffic." The high revenue types effectively subsidize the low revenue types. This model happens EVERYWHERE in the regulated universe.

I wouldn't be surprised if the regulators were also simply trying to maintain their nests by maintaining control, and maybe some actual hard corruption.

But these folks are very, very capable at city politics. They've got their 10,000 hours in and they will kick your ass if you don't. I don't care how right Uber is, if they find themselves going up against race and class politics they will get erased.

My advice to Uber? Slow down. Figure out what the other side is about, and I mean all about, good and bad. Figure out how you're going to meet the real problems and the legitimate and / or understandable objections of the incumbents. Figure out the arena where the final decisions will be made (probably the city councils), get to know those players, and figure out how you can win there.

Uber can't probably do this on current staffing. They need first class political advice, and at a local level. Finding the right people won't be easy. But they need people with those 10,000 hours in the right places, and pronto.

Lines Blur as Texas Gives Industries a Bonanza
Life: Quitting a stable software job to do a PhD in Finance. The additional technical skills (Writing, Mathematics, Finance, Law, Accounting) and interpersonal skills (Networking, Explaining complex topics) I've gained have been invaluable. I now look at the world in an entirely different way.

I share the same feelings as marcamillion regarding having the "veil" lifted on world affairs. I have a BEng in Aerospace Avionics (Electrical Engineering for air and space craft) but have always worked as a Software Engineer / Developer. After a few years of working full time (big multinational then small ~20 person company) I was wondering "there has to be more to life than this."

While reading online I came across recommendations to read this weekly magazine called "The Economist". It was super hard to get through at first: I didn't know the people, some of the countries, or the financial jargon. But I persisted and each week I'd go and buy it at the newsagent. I'd systematically read each issue from cover to cover. Those first ~15 issues looked like a rainbow; multicoloured post-it notes fanning out from three sides. Whenever I came across a person, word, country, concept I didn't recognize I'd write it on a post-it and affix it to the page. Later, I'd systematically revisit the notes and resolve my ignorance using Google + Wikipedia.

A lot of the time I didn't want to read the whole thing, only the Business, Finance, and Technology sections. However, I forced myself to read about issues in Sudan, or Kyrgyzstan, or politics in South America. I am now so much more aware of the way the world works, what's happening in world politics, financial markets, business, literature. As marcamillion mentions, acquiring this knowledge was liberating.

Programming: Persisting with Haskell until it "clicked".

Over the past 5 years I've revisited Haskell a number of times. Reading tutorials and books; watching videos. I "got" Monads as a mathematical concept, but didn't have a strong grasp of how and why they should be used.

On about 6th crack at it I just sat down and read code. Thousands and thousands of lines of code. Once I'd "groked" a concept from seeing how it was used in real world code I'd go and implement it from scratch. I'd recreate Maybe, then build the Monad typeclass, and finally implement the Monad typeclass for Maybe. I'd do this for Monad transformers, Monoids, Applicative, etc. This was really hard for me. Looking back I realise I was optimizing my learning by always pushing the edge of what I could do.

Over time I gradually became competent at writing Haskell as well as reading and understanding other people code. This additional understanding of functional programming has dramatically change my programming style. I now create a lot more immutable data types. In C++ I'll liberally use const, in Python namedtuples. I get frustrated when a language prevents me from easily mapping and composing functions. I really really value algebraic data types and use them wherever I can.

tl;dr Read The Economist and went to grad school. Learned Haskell and now use immutability and pure functions much more often.

Still, I'm not sure I approve of your suggestion to use this physical property of the universe as a basis for intuition. The reasons why quantum mechanics "works" are far, far more difficult to understand, internalize, and accept than the concepts behind the DFT which only really requires an understanding of first-semester linear algebra. In other words, I expect that the set of people who understand QM at this level but do not understand the DFT is nearly empty.

If you actually meant to go the other way (use the properties of the FT/DFT to gain an understanding of QM) then I completely agree with everything you said, of course.
I suspect the more likely reason is that they didn't want to lose employees who decided to quit to go home and raise kids.
But don't all smartphones have email notifications?
The problem isn't that people don't care.

You are right, people care. But not about things that would make reducing government power likely nor encrypting things by default probable.

They care about getting to work in the morning and getting home at night. They care about dinner with the family and a couple hours mindless television. They care about being safe while they do these things, and they've fully bought into the government's mantra of "we will protect you", so, as long as that's happening, they don't care about anything else.

Go talk to just about anyone outside of sites like Reddit or HN about the TSA, and you will be told how good a job they are doing. When the government tells them it is time to randomly drop their pants for the cavity check, as long as they are told it is making them safe, they will willingly oblige.

As much as the government's power grab, the complete lack of concern for it scares the hell out of me.

Maybe the things you were putting a lot of effort into weren't things that helped you master those materials. It's possible to work hard with the intent of learning something, and never learn it, even though it's within your capacity to learn, if the thing you're working hard on doesn't help with learning the thing you're trying to learn. In fact, I think most of the effort people put into learning things in the standard educational system is wasted.

I mean, it's also possible you're struggling against some kind of mental handicap. But if your IQ was really 75 or something, I don't think you'd be able to write such long sentences.
Wow, from the headline I was hoping somebody was finally making a standalone "retina" monitor for high-end consumers. At $5500, this isn't quite still hitting that target.

Still, IIRC when I first my first high-resolution monitor (a 30" 2560x1600 display from Apple, who made displays with that many pixels mainstream) it cost $2000, and I had to buy a $900 video card to drive it. This was maybe in 2006.

Within a couple years though, you could get a similar rig for a little over $1000 and then-current Macs and PCs could drive it (at least higher end models).

I hope we see similar progress here. It frustrates me that when I sit down at a desk to work I have to stare at these gigantic slabs of what (now) looks like huge pixelated crap, when my tablets, phones, and notebooks are all high-PPI.

I use multiple 30 and 27 inch highres displays for the workspace they give, but they really look like crap in the modern high-ppi era.

As far as I can tell it has nothing to do with marital status, ie married or single. It has to do if the person is crazy. You can hire or not hire people based on personality and fit with the company, so I'm not sure why the spouses personality and their relationship fit for the company would be off limits.
I think the simple way around that mess is to give $28 to your friend, brother, aunt, uncle, girlfriend, or anyone else you know with a pulse that will follow through.

I'm a little confused as to why they wouldn't have done exactly that.

Great article. After having lived most of my life in urban areas, I married a great woman who has a very rural job and we live in an incredibly small town. I'm an introvert and solo entrepreneur, but had found that I thrived via in-person collaboration at a co-working space or via meetups.

What I've been struck by is the difficulty in shifting. Maybe I'm not looking in the right places online, but I've found it difficult to make new friends on the internet, or get the same sense of camaraderie as in-person contact.

Anyone have any advice on how to break the ice and make "internet friends" ?
FTA: "While the regulators discussed ways to clarify the legality of these apps, they also proposed guidelines that would effectively force Uber, a San Francisco start-up, to cease operations in the United States."

These regulations and agencies were created in response to a wildly different system of car-based transportation from decades ago, one where drivers, agencies, payments, customers, and misbehavior were all harder to track and punish. A gypsy cab could operate unsafely, mislead customers (especially out-of-town visitors), and disappear with cash: no recourse.

Uber and more generally the category of mobile-dispatched-and-paid transport are now so different from that past that the best approach will be to let them operate to see what happens. The fears about 'anyone in a basement' preying on consumers and then disappearing reflect a pre-internet, pre-mobile, pre-credit-card mentality and may not be relevant at all, except in the imagination of threatened incumbents and bureaucrats.

New restrictive guidelines, like those from this "International Association of Transportation Regulators" conference, should only be crafted in response to any actual abuses that materialize. Even then, they should only be deployed to the extent that the standard laws of consumer protection (implied warranties, truth-in-advertising, liability law, etc.) don't work, and competitive consumer choice (aided by their mobile devices) doesn't work.

(There used to be special informational failures in cab-dispatching that made the usual consumer protections not work well. Those failures have been solved with mobile/reputational dispatch-and-payment. Every person, car, dollar, and ride is now far more accountable, even without government regulation, than ever before.)

These appear to be daily guided meditations, not just doing Zazen every day.

That said, I think the guy doing the videos (Andy Puddicombe I believe) does not have a good voice for this, or at least needs additional vocal training. He's nasal and too high pitched for me to be relaxed by it. I'm on edge after listening to one video. Perhaps a sound guy could fix it, but I'm guessing he's doing to have to go to a coach to learn how to get the nasal out and how to boom his voice a bit.

Hi, I've been researching the car buying space for several years and started the site RealCarTips.com. Here's my take on this:

There's currently a site called RollSale (http://rollsale.com) that's doing something similar to this.

There's also AutoTrade.com Trade-In Marketplace where you can get quotes for your trade-in (https://tradein.autotrader.com)

But the problem I see with this business model is that any quote you get from a dealer for a vehicle they haven't personally seen and inspected will not be a reliable bid.

They can always do a bait and switch after you bring the vehicle in. Now that they have you at the dealership, they can wear you down and convince you to drop the price due to "unforseen" issues. Perhaps the vehicle is not in the condition they expected, or there's some mechanical "issues" and they can't honor their original bid.

I don't know of any dealers that will absolutely guarantee a used car bid sight unseen (unless they bid way below market rate), which isn't good for consumers.

Not saying this business model won't work, it's just hard to get guaranteed bids.

Edit: I may have misunderstood the question, but I'm assuming this is a service where you try to sell or "unload" your car to a dealer.
Upgrading RAM on new iMac practically impossible
This tutorial is really great. It not only covers UICollectionView, but also walks you through some wonderful design and interface polish. Definitely worth the time.
Good pts.

This was born out of personal frustration and gap we saw with the online lead generation services in the auto space.

Dealers wanted a qualified ready buyer. A used car seller (or trade in) wants to know what they can get for it.

If we can make it a guarantee (like Truecar) that you'll get that price when you visit the dealer, then wouldn't you try it and visit the store?
>> My advice to Uber? Slow down. Figure out what the other side is about, and I mean all about, good and bad.

I agree with most of what you said, except for this. They are in the land grab phase. If they don't continue to expand aggressively, someone will eat their lunch, ala Groupon.

My advice is for them to take some serious funding, and start cutting checks to lobbyists, PR, and god forbid, politicians. Play the game.

I feel horrible saying it, given that it helps feed the machine, but it's their only option to build a truly disruptive business in an area that needs disrupting mainly because of regulation and bureaucracy.

Google and Microsoft both learned this lesson too late, and it's hurt them both dearly.
