Your comment is spot on except your hyperbolic and unnecessary attack on social security.

Groupon figured out a way to sell a dollar for $.50, and they use money from new investor's to pay the old-- just like a ponzi scheme.

Also what does Groupon have? A few thousand merchants, a few million email addresses, no patent portfolio, no moat so to speak-- and the fact they need 8000 employees mostly dedicated to sales means they can't scale well--ever.

Most likely Groupon has 6 months to a year before the money evaporates. If not then they end up like Avon or Snap-On tools at best.

Legitimate Business Tips From An Ex-Mafia Man
It does. There's a whole lot of research into how insider information propagates, and what the ideal portfolio strategy is given such information.

But it's like any other edge. It can still make sense to diversify. That's empirically true; even Boesky put most of his money into stuff he didn't have an insider edge in.

In this case, it all depends on what kind of edge Lefkofsky has, what kind of liquidity discount he's willing to deal with, whether he and his investors have different time preferences, etc.

It would be truly odd if the rise of the fastest-growing business in history and the rise of the first fairly liquid pre-IPO market and a massive increase in the US money supply didn't lead to this kind of change in investor and founder behavior.

Why i switched from Things to Omnifocus
It's amusing that Rails is now considered a heavy framework. I remember writing my first Rails app with Rails 0.8. It was a tremendous breath of fresh air then. Seven years later it's the bloated incumbent.
2 reasons why:

1. In China, copying is better than innovating. If you copy, you have no risk, because you will make money by undercutting your competition. If you actually innovate, there's a lot of risk, and the potential upside just won't justify the risks. So techies are useless (except for reverse engineering foreign tech - and cutting costs). Now that the US and Japan are possibly cheaper after accounting for better productivity (guess those techies aren't worthless) and stabler conditions, this will change.

2. China is capital constrained. You can't start a business because getting money is too bloody hard. Sure, you can get a bank loan, but the banks only loan to SOEs. So bosses get a lot more money than plebs. Once again, this is changing, but not as fast.
Agreed. This is why I really, really hope Rubinius manages to become "worth it" soon (or at least JRuby). The MRI core team, Tenderlove excluded, seem to give approximately zero shits about Rails.

true enough, but i also think that we say that myspace had a lot of social at the time was because it did _at the time_. There was no facebook back then so myspace was really the best at offering social features even though, by comparison against today's players, it didn't have much.

Agreed, it makes way more sense to just put a 'snippet' tag on the entries for code snippets.
I haven't actually programmed in Haskell, but once I started reading about it, my pseudo-code started to look like it, especially type declarations and inline conditionals. Other times, I use more Python-y (won't say Pythonic) syntax.

So even in one person, it can vary.
Exactly, the less external assets you load, the better. But you're not always in a position to be loading just your own assets. Sometimes you'll use 3rd party scripts and in that case as many of those need to still go at the bottom as possible. Take the Twitter @anywhere library for example. It's non essential to the user experience and shouldn't be at the top blocking the main page from loading (especially given its wildly variable loading times), so it should go at the bottom.

I think this would be an interesting twist on the "slowban" from the article. It would certainly impede argumentative behavior.

I almost made a snarky comment on the sf comment section about how they aren't the most unpopular kid, there is always java.net!
I want to get on a tangent inspired from your comment. Myself included, many Hacker News readers would probably be in the BS-detecting, questioning, critical category of students. However, I personally really think that every school child can become great at something, regardless of whether they are the little questioners in the classroom or not. And I personally think that an education system that labels children into "regular" and "advanced" is not a good idea, because it really hurts the self-esteem of the "regular" students.

My point is: different flavors, different emphasis, different difficulty in homework among the essentially same-subject classes is fine. However, we should phrase education as an experience with choices, especially for pre-college (because their personalities are very malleable, imo), instead of making kids feel like they are laggards.
Power without transparency inevitably leads to power that is abused. In the west we have built our civil systems around that theory.

What are we risking by not having this transparency on HN? By not having transparency on what accounts are banned, and why? Only the value of the discourse that occurs here.

If the value of the communications that happen here is high enough, our interest in having protections for that communication should be just as high.

If the value of this discourse is low, why are we putting on airs and pretending we need harsh measures, such as slowbanning, to protect it?

Sooner or later, any human, even one as benevolent as pg, will abuse their power over others. We need access to the reasons that accounts are secretly banned or slowbanned, so that we can pressure moderators (or whoever has that power) to wield the punishments fairly, and petition for unfair punishments to be reversed.

There are almost zero barriers to entry. Groupon has a list of a few thousand merchants, a few million emails, 8000 employees, and sells a dollar for fifty cents. How can you scale with so many employees and ever be profitable? It's not sustainable at all. They have no patents or any semblance of a defensive moat. Groupon is also declining in the cities it first launched in like Boston. Their future does not look good.
I like your implementation/UI better... very little change from the existing site!

Ask HN: Autograph my MacBook (An Experiment In Word Of Mouth)
It started when Woz autographed the lid of my MacBook as I stood first in line for the iPad launch April 2010. Second, I asked Guy Kawasaki to autograph my MacBook. He obliged. I put a clear Spec Case over the lid to protect the signatures.

People now ask me about the 2 autographs and the typical what, why, when questions. People I dont even know come up to me and ask me about the autographs and who signed it.

I got to thinking, I wonder just how much word of mouth would get people to sign up for products.

So my quest is to collect a few more autographs. When someone asks me about the signatures I will tell them about it in as much detail as they want.

So here is a chance to promote potential business. Autograph the lid to my MacBook and I will promote your business. I am in San Jose but would be willing to meet where ever to execute.

Here are some people/companies that I would be interested in promoting since I use/believe in the service.

Drew Houston / DropBox

Jack Dorsey or Ev or Biz / Twitter

Kevin Rose / Foundat.io/n

Tony Conrad / About.me

Phillip Rosedale / SecondLife

If you are not on this list, but interested, hit me up. E-Mail in Profile.

Lets promote word of mouth business....
Kudos! Very nice! ... now for the back end! :-)
Presumably, Periodic was referring to Rails' emphatically opinionated framework, which (under the right circumstances) can shine a light on at least one approach to SoC that may, in turn, lead to a deeper understanding of the underlying principles.
Thanks for reviewing the site! Yes, that was me, we've only recently launched. We're hoping more people use it for nags so the supply will be greater. Did you get the actual email from the system or the manual override email?

Edit: By the way, you were the 1st person to use the site who was not a builder or tester. Congratulations!
USRP is much more sophisticated and capable. Unfortunately it is pretty expensive.

Anyone knows of a reasonably priced board suitable for GSM implementation (has to have both receiver and transmitter)? Perhaps a combination of low cost evaluation boards? Baseband should be relatively easy. It's the RF (down and upconvertion/amplification that are more difficult to find).
Thanks! They work too, the nags I've tried and other testers have tried have been done.
Bubble? What bubble? Things are great. Unless…
Yeah, this is one of those articles best left until you get to a desktop or at least your Android tablet. ;)
Based on the way the search API works I don't think this is feasible. "dropb" is not a token that the system recognizes as being part of "dropbox" so I think dropb essentially returns no results. It would be nice if they had some sort of autocomplete functionality. That is how Google Instant works- it makes an educated guess at what your query will be and uses that rather than using the partial query. It's pretty effective much of the time.

Seems like ThriftDB is still in a pretty early stage of development so I doubt that they support this. But autocomplete is a solved problem so I'd be surprised if it doesn't make it in at some point.
People really don't want this?
Done, there ya go.
I found it incredibly frustrating that for whatever reason the author decided to have A for location and L for audio. Perhaps this is a bug?

Wow, hits close to home.

I tend to see it as the bi-polar disorder of learning. There are periods of maniacal interest in a certain topic. I can acquire vast knowledge in a matter of very short time yet it always quickly wears of.

The lack of immediate recognition, reward etc. is definitely a factor.
I too always knew school didn't mean much, but being straight A has always been sort of a thing I had to do, it was my responsibility.
How could I let other people see I am not the smartest guy?! Haha.

I was actually thinking about finding some projects partners on-line in a similar situation so all of us could work to gather on fairly simple projects (and perhaps building those out later on), it's definitely far harder to just dismiss a project if there's other people expecting you to perform.

I know I have all the capability to deliver crazy performance. And hey, I still do from time to time, it's not like we're doomed.
We have already proved that we have the mental capability to achieve great things, now it's time to utilize it.
The single return is also useful for post-condition assertions of return values and internal state.
What could the MRI team be working on that's more important than fixing a bug that quadruples startup time for the most popular Ruby applications?

Step 1: Learn to speak Japanese. Step 2: Express that the startup speed of a project that, IIRC, none of them use and that doesn't pay the bills at their day jobs is Really Really Important To White People and that anything which compromises its utility -- which should be checked exhaustively at every release -- should block shipping.

I use Rails, and love Rails, but back home Rails is not yet the core Ruby use case, not by a long shot. Rails has peculiar needs with regards to typical Ruby applications, and a certain portion of the developer community feels that people who write themselves peculiar needs can write their own solutions to them. (i.e. "If they're going to run tests every few seconds and load a thousand files every time it runs... why is poor performance our problem again?")

Apologies for being a wee bit snippy but variations on this discussion have come up before.
Simple, Google is worried Groupon theoretically could get a huge share of local advertising like they were with Yelp.

Google isn't infallible, they are mortal. I think most likely they were willing to overpay because they could afford it and are desperate to get into "social".

Also, Groupon is a ponzi scheme because they use new investor money to pay old investors--not because they don't have a moat, which they dont-- no patents, 8000 employees and how do you scale with that many employees, a list of merchants and user emails.

At best they end up looking more like Avon.
I think there are a great many topics (libertarianism, moderate religion, socialism, …) where your assessment of the situation is spot on – but …

I wonder whether nice articles about beliefs which are most certainly crazy (creationism and biblical literalism, astrology, homeopathy, rapture, moon conspiracy, …) really are useful. They sometimes might be but in most cases the believers are beyond redemption.

Those articles have a different purpose. Rallying the troops is a valid reason for writing such articles.

(Well, and sometimes it’s just good to be able to vent about stupid things someone else did. I don’t think there is anything wrong with that.)

On the topic of loops which end in a break ("Most egregious is the loop whose last statement is break;!"): this can be useful for avoiding contorted control flow when you have a switch statement inside the loop. Instead of coding:

cont = 1;
while (cont)
{
foo = bar();
switch (foo)
{
case 0:
cont = 0;
break;
default:
// other work
break;
}
}

You can do this instead:

for (;;)
{
foo = bar();
switch (foo)
{
case 0:
break;
default:
// other work
continue;
}
break;
}

IMO the idiom, once you're used to it, reads better.

(Yes, I know you can reduce the lines further e.g. putting foo=bar() into the for statement, but it's the multi-level break I'm focused on here.)
The HOPL books & papers are great, too. Most (if not all) should be available on citeseer / google scholar. I have the HOPL II book and trivially found all the papers from HOPL III online.

I particularly like the history papers for Lisp, Lua, Erlang, and Forth, but, personal biases.

Another good one: Sammet's _Programming Languages: History and Fundamentals_. (The superior design of Lisp and APL gets asymptotically more embarrassing in retrospect.)
I get the impression Peter Landin was ahead of his time. I love this paper. It's worth a read by anyone interested in compilers or functional programming.

Isaac, do you think you could add this problem to the shootout? I believe (and am therefore almost certainly wrong) that there isn't any benchmark there that derives almost purely from compiler theory.
Bummer.

Someone -- I think a startup founder I know and that people have heard of, but I could be wrong -- related to me that when he got a series A or B, the background check was so thorough that the investors noticed he'd accidentally let his drivers license lapse and had an unpaid parking ticket.

You really don't think Python is reaching the point where a manager type would be comfortable with it? It's mature, it has tons of libraries, it's used in all kinds of successful projects. I really don't know. It just doesn't seem anything like a high-risk choice to me.
That's not even true. Plenty of startups use the languages you mentioned.

When Rails first got released, there was a certain wow factor - it made making sites very easy. There have been plenty of web frameworks released afterwards for other languages that made it easy to spin up a new web project, but Rails has remained ahead in terms of how much mention it gets, for various reasons: first-mover advantage, its community is louder, etc.
Awesome, did not know that. Would be cool if you all made this default when you get SearchYC back up and running.
