I like the Uber concept and like most people I know, can feel for people having troubles with taxis.

But after I noticed the 3rd invite-to-uber link I got worried that this is just a piece of marketing. The count reached six and the closing words were again a call to action to sign up. A quick search seems to indicate that you can get benefits from the company, if you invite new users. Which someone is _desperately_ trying in my opinion.

A disclaimer would've been appreciated.

IPv6 is an _awesome_ protocol for telemetry networks, and for mobile networks in which address mobility is required for millions (or 10s of millions) of devices. All of the carriers/companies that I talk with from time to time who need to deal with those two problems (> 10 million devices, and address mobility, that is, those 10 million+ devices can move around from network to network quickly) - see a lot of value in IPv6; it's the right tool for that job.
Atlanta can probably rival Philly when it comes to violent crime and corrupt institutions.
As someone from Atlanta, I can confirm that there is a growing interest in start-ups (or at least at GT there was). My goal after grad school is to start a company; I just don't know in what yet :)

I should mention that it's difficult to characterize all people in Atlanta under one sort of personality type. In my experience, it varies wildly. Atlanta is more of a commuter city where a lot of people from the suburban area surrounding it drive to work each day. Of those who actually live in the city, I believe liberal is more frequent (particularly in the Midtown area), but again, there is a wide variety.

Atlanta has a reputation for crime, but this has actually improved significantly since the Olympics and I don't believe Atlanta is any worse than other big cities now.

There's also a variety of things to do in Atlanta. Some examples including the High Museum of Art and many local jazz clubs. There's also a number of outdoorsy things. Two prominent bike trails (Silver Comet and Freedom/Stone Mountain trail) + a new one they're building through Atlanta called the Beltline.
Crime is a downside, but it's also one that's not uniformly distributed throughout the city. And to be fair, Atlanta isn't a low-crime city either.

Lots. For example, that every set has a cardinality (is bijective with some aleph). That's pretty intuitive, too, as (I think) are the following.

* Let X and Y be sets. Then either they have the same cardinality, or one is smaller than the other.

* Let X be an infinite set. Then there is a bijection between X and the cartesian product of X with itself, X × X.

* Tychonoff's theorem: every product of compact topological spaces is compact.
From what i heard of people who were at CNN when it was a startup, definitely so.
Unfortunately, explaining this will take more than a sentence and it's 00:30 where I am and I need to sleep. But in a nutshell, the whole industry relies on a heady mix of stupid investors, money launderers and state backing. The only people that make money are the brokers (as in most industries...).
True. Though if we're going to argue what is the most reliable way to get to JFK from manhattan during rush hour I'd offer LIRR as the best option, since it doesn't get stuck in traffic...
An interesting rant. I've observed that problem solvers also follow something like the inverse power law, which is to say it takes a certain kind of person to attack large problems and as the problems get larger the set of people willing to consider them seriously decreases logarithmically until it asymptotically approaches zero.

In an analagous fashion the "quality" (using karma as a metric of quality) of comments on HN are also quite high and drop off steeply approaching zero. This is reflected both in the comments, and in the karma distribution [1]. The trick is to keep the noise floor high enough for quality reading and low enough that you don't miss out on new people making great comments.

It would not initially. However, if there are a few big successes, the cost of living would rise. But even then, it would be concentrated in the areas considered attractive to the newly successful company employees and people in the secondary economy serving them.
It is? What interesting thing has come out of Austin anytime recently?
Does it bother you that by dividing all the integers into odd and even numbers, I can end up with two infinite sets, each of the same size as the original set?

While the Banach-Tarski violates your intuitions, it is probably because it is more about how there are "multiple copies" of the real numbers in the real numbers, than anything resembling a real cut.
Traffic isn't exactly a picnic in Silicon Valley. And on the traffic front, there is a key advantage to living in Atlanta: while it's not possible to live entirely without a car in the city, it's entirely possible to live close to work inside the city, because rents are so cheap. Traffic inside the city itself really isn't that bad--it's traffic in and out of the city from the suburbs.
Yes, absolutely I'm curious. I've been dreaming about it since moving the little LOGO turtle triangle around on my green-and-black Apple IIe. But despite that circa-1960s idea, I still use `scp` and grep to get-things-done. Come on, people, it's 1982! We should be dreaming of electric sheep by now!
The heat dissipated of the two metals would be identical if their resistances were the same, of course. I'm not even considering the difference in amperage between a 110V and 220V connection, as I'm pretty sure that's not what the parent parent post was in reference to.

I was under the impression that the issue at hand was that using solder for high-load wires was bad because of solder's extremely low melting point. I meant to point out that even though the solder is just holding the wires together, there is still a current running through it, and if the resistivity of the solder is lower than that of the copper, the chances of the solder melting would be quite a bit higher.

I honestly don't know if that's why the parent parent post mentioned that soldering high load wires are bad. I just extrapolated issues that someone might have when using solder on high load wires, and relayed them in my reply.

Show HN: Freeholdr - a friendly, social condo property collaboration service
I love this!

To get it to work with my mixed Padrino/Sinatra rack app I had to do this in each app:

if PADRINO_ENV == "development"
set :raise_errors, true
set :show_exceptions, false
end

and

use BetterErrors::Middleware if PADRINO_ENV == "development"

in my "config.ru".

I'm not deeply familiar with Padrino or Sinatra and so it took a lot of experimentation (and source reading) to find the right incantation. But it's working great now!
I was puzzled by the statement that he didn't learn much from the classes he took in formal logic.

>(Consider "I don't know if I learned anything from them. " Footnote: 1 "In practice formal logic is not much use,..." )

This guy has programmed massive amounts of LISP code, and written books about LISP.

How can he say that his training in formal logic didn't take him anywhere?
My first thought: Could I put my phone in a radio-proof room, and externally synthesize the GPS signal to put my phone wherever I wanted, complete with robo-play as necessary?

My second thought: If it's possible at all, I have to assume this is already being done.
If you want to build a business and not side projects you need business development and marketing.

There is a bias(extremely wrong in my opinion) in HN against this and that product is everything but real world business doesn't work like that. Unless you have a viral product(which still needs marketing to reach critical mass) it is marketing that will make or brake it.

Also .io and other extensions might be trendy and fun to use but real businesses use .com . If you target end users they will hardly remember the tld of your website. How many services that end up in .io or other similar ones do you use?
It would also be interesting if they publish team size distribution vs. previous years, since many of the S12 problems seemed to have been team related. Would this mean more single-founder teams, or more teams with a founder with controlling interest, or more teams with brothers (like Stripe), ...?
> "Going to Newark airport however cost me something like $110 if I remember correctly, because the cab driver gave me these special "fees" at the end, it felt like highway robbery."

It is. There is no flat rate to Newark airport, so you can either take the metered rate or negotiate your own flat fare. Bonus of the custom-negotiated fare is also that customarily you don't tip on it.

There's no good reason why going to EWR from Manhattan should cost $110 (short of complete and utter gridlock). Insist on negotiating a fare, or just call a car service - their vehicles will be nicer, the driver will be less surly, and the price will be substantially lower.
Why do FreeBSD users always have to 'defend' their choice. I wonder if every time someone tells me that they run some distro of Linux I should ask them why they don't use FreeBSD.
This article http://moongadget.com/origins/dune.html has a chart comparing story line points. I am unable to locate my copy of the book "The making of dune" in which Herbert considers taking legal action about the similarities, but decides not to.
Yeah, good point. Several of my coworkers are from my company's offices in Canada, and when they are down here they always insist on getting a cab. It always turns out bad, because they always seem to be leaving at rush hour. I wish I could convince them to either just book a car or take mass transit.
It doesn't do it on the real numbers at all, it does it on a subset of rotations in R^3.

You're right that these aren't "pieces" in the intuitive visual sense. That's why Feynman ridiculed the result, because in the initial description given to him he assumed physical pieces, not pairwise disjoint sets.

This looks really interesting. I'm excited to see someone is working to bring GitHub to iOS.

Looking at the screenshots, it looks like it could use some UI polish (http://worqshop.com/). For now, this will keep me from dropping $5 on this. My primary use case would be writing text (not code), and for that I value the great UI/UX of iA Writer over being able to save directly to GitHub.

I'd be curious to hear what other common use cases there are for this. In addition to writing text (Jekyll-powered blog), I might use this to make quick fixes on the go or review issues/pull requests.

It seems like actually writing significant amounts of code on the iPad is probably not a common use case. I refuse to believe this is productive compared to using a real computer with multitasking, Vim/emacs/Sublime Text, etc.

Anyway, if this were my app I'd focus on making the experience great for doing issues/pull requests and typing text (in comments on the aforementioned or in files). I wouldn't focus on actually writing code. But it's clearly not my app :)

In any case, great work -- I'm looking forward to seeing this app progress.
The drawing on the page is confusing. It depicts the "pieces" as contiguous solid chunks--but in order to reassemble the sphere into two, don't you have to pick sets which are more like general predicates on the points of R^3? Those don't look like puzzle pieces.

It's like depicting the irrational numbers by coloring everything on a number line between pi and e blue.

Is it possible to do the cut-up-and-reassembly trick with a finite number of sets where the membership is computable? If so the "Banach-Tarski Algorithm" for the special case of duplicating the sphere might be helpful for understanding.
It looks nice, though the design is so smooth and monochromatic I wonder if people would find it more appealing if there were some generic housing photos as illustrations. I'd also suggest using screenshots to give people a better idea what to expect. It may be worth thinking about a more slimmed-down sign-up process that lowers the barrier of opening a test account and enables people to play with the app right away. It's clear a lot of effort has gone into this, keep it up!
No worries, I'm american and caught on.

Yes, medicine is not finished yet (we haven't cured death yet). However medicine hasn't stopped yet and keeps researching. And medicine is waaaay better than it was 50, 100 or 150 years ago.

That's pretty annoying, actually, but it's a good example of what can happen when these services (used by millions of people) change hands.

On a related note, Cinemagr.am, which I find pretty interesting, should also focus more on their own website instead of relying completely on Twitter, Facebook and iOS/Android apps...
This is a 5 million people area. It would take a handful of Microsoft sized startups to make that needle move.
Consoles drive and constrain game design in several important ways. UI is a big one (how many management sims are playable with a gamepad?), but RAM is probably even more important.

The demand for ever-fancier graphics on aging, static hardware means that every other aspect of a game suffers. Smaller levels, fewer options, simpler AI, etc. This is why the next generation of consoles is going to be such a big deal for anyone who plays major cross-platform games.

For games that require a more complex interface, there's still a thriving PC-only games industry. And now Kickstarter is helping to power it.
I have been told for years I need to promote my own work. It does not work for me. In fact, it backfires hugely. I am seeing gradual inroads to more traffic from trying to prove myself. People get interested in me, think I am smart, traffic follows. For me, it hugely, hugely backfires to try to "promote my site".

I think my situation is extreme but I don't think that principle is unique to me.
My plan for the year
Its my aim to get into programming, and would appreciate some feedback from the community with the direction of my studies for 2013,

1. Learn MySQL
2. Learn ecommerce

Generally however I want to master PHP and improve design skills using photoshop and keep designing websites using html css, and the above when I learn them.

Is that enough for a year?

Have any recomendations?
Actually, I do. That's part of what has made this design challenging for me. The next thing I build will have a ...somewhat different layout.
Proposal: HWIGS HN: How would I get started
In light of the wonderful article about "How would I get started" on Hacker Tourism - http://news.ycombinator.com/item?id=4894990 - and the ensuing discussion, I propose a simple solution.

HN is filled with wonderfully intelligent, well-meaning and thoughtful people.

So, just like we have Ask HN, Tell HN, Ask PG, Tell PG...I propose 'HWIGS HN'.

Where each thread is chock full of ideas that can help the person wanting to achieve something.

E.g.

HWIGS HN: Building a bank entirely online

If you have something to contribute to building a bank online, you can chime in. If you don't, do not.

If you bring negativity and uselessly detract from the discussion of that thread, all HN members are obligated to downvote you into oblivion.

If you have nothing constructive to say, then don't comment.

That being said...that doesn't mean you need say everything positive. E.g. if the idea is bad (or there are particular pitfalls based on research and experience you can draw on), feel free to chime in and provide that information in a non-emotional, non-trolling way.

Even if this never leads to any of these things being built, I think it would be a good thought exercise for the community.

Plus, it will help us to learn more about other industries we may not be directly involved with - and perhaps hear from users that don't have as much karma as patio11 =)
which would you prefer?
- Prezi
- Sliderocket
- Keynote
Thanks so much. We are planning on a video shortly that will be right at the top of the home page (where the sunrise graphic is). I agree with you that we need screenshots... we'll have to figure out a way to integrate that.

I appreciate your feedback. :-)
You might be right. The more I learn about the real numbers, the less real they seem :/
How ignorant. Not to mention that the city of Atlanta votes overwhelmingly blue.
I used to, but then the crunch hit the london VFX scene, and I was made redundant. I'd love to get back to a VFX company.

This is incredibly fascinating to read. Thanks for the links and insight.
When you actually want to implement those other sites, you can replace the function by a class with a __call__ method.
This may be a stupid question but what do you mean by "Style Influence"? Googled it and still I couldn't figure it out :(
I'm confused by Atlanta -- it seems like a very racially polarized place, but it's not split across wealth/professional status/etc. like the racial polarization in SFBA -- it's just parallel everything by race, which is even weirder. I actually know more black people in Atlanta than I know white people, since a lot of the black military officers I met (who tend to be middle or upper middle class, either going in or coming out) had some connection to Atlanta.

There seemed to be a lot of interest in business startups, but not the kind of scalable tech startups you would find in the Bay Area -- more like consultancies or other professional services. Still, a good way to a $200-300k/yr income. They may have been as much a "getting out of the Army" thing as an Atlanta thing, though.

Imagine, as a thought experiment, that HN declared a do-over and took another stab at answering the question. What, specifically, do you want in the new thread that was not present in the old thread, and what do you not want in the new thread that was present in the old thread?

Some potential options:

a) Keep all the facts. Remove conclusory statements which suggest that this is a bad idea.

b) Remove the discouraging facts. Add new facts which tend to not be discouraging, such as "Monthly cable rates are high relative to many B2C products and lifetime values can easily hit the thousands of dollars, allowing you to spend a lot on customer acquisition." Add conclusory statements suggesting that this makes founding a cable company a good idea.

c) Remove discouraging facts about the cable industry, replace with to-do action items which accurately describe the process of how one would set up a cable company (regulatory approvals you'll need, who to hire, how much to raise, etc etc), and very carefully attempt to phrase "Convince investors to stake you with $X0 million" in such a way that it does not sound discouraging.

d) Remove everything about starting a cable company. Treat the question as a springboard about "How to disrupt the cable industry?"

e) Something else?
It's not clear. Many Mac ports are done with Transgaming's tools. Which are commercial and include code from old BSD versions of Wine.

Microsoft isn't actually obligated to sue, so they may have just decided that it wasn't worth while.

The Google/Oracle API copyright decision probably helps Wine.

So they're probably in the clear, but Microsoft could certainly make their lives difficult.
The fact they act on a whim is beyond dodge.
I second this, cool :)
>"I’m really disappointed in the universally pessimistic and generally unhelpful answers this question received. Some people pitched some interesting ideas and helpful analysis, but most of the replies reinforced the notion that Hacker News readers are predominantly male know-it-alls and on the average, a bunch of snarky dicks."

This would have been both more convincing and shorter without the anti-male bit. I realize that western media is pretty insensitive to this variety of sexism, but a quick test is to try substituting "black", "female", or "Jewish" where you've written "male". If it sounds offensive, then it probably is.
I just submitted a propsal for a new thread format on HN that would potentially solve this. Any upvote love would be appreciated - http://news.ycombinator.com/newest

You convert the files via whatever does conversion. The same as any other SSG.

The difference is the layout of the data. In a wiki the data is usually laid out hierarchically. Regular static sites are not. Most that I have looked at create blogs.

I'm caling it a wiki because with the exception of not using a browser it should be one.
Ditto DC. Ditto Chicago (though it's better). NYC cab service is by far the most consistently reliable this side of the Atlantic... once you get the rules down.

One largely unknown tip is that there are many formal cab stands around NYC. At these, another human being helps you navigate the rules and hail a cab. They are great for the elderly, tourists and any of us when we have a big package or a lot of bags. They are also often covered (see: cabs-in-rain problem), discourage 'up-streaming' by other would-be riders and they seem to attract available cabs (cabbies seem to favor the known quantity). A few are official NYC TLC operations (airports, train stations, etc.), but many are free-market concerns (nearly every hotel).

Here's the NYC Cab app I want:
1. Identify and map these cab stands;
2. Report if they are 'open';
3. Show demand (number of people waiting), and;
4. Show availability (number of cabs waiting).
No can't use that.
