Also, the original wording is not clear, IMHO.

"On Debian GNU/Linux this file is a symbolic link pointing to /var/run. The contents of this file are regenerated upon every system boot based on the contents of /etc/motd.tail."

It should probably read:

"On Debian GNU/Linux this file is usually a symbolic link pointing to /var/run. The contents of the file in /var/run are regenerated upon every system boot based on the contents of /etc/motd.tail."

To make it clear that the programs that generate the contents target the file in /var/run, and do not operate directly on /etc/motd.

Web application development is not for beginners.
Failure is a relative question. I've been part of 2 startups that still exist as profitable ventures, but in my opinion failed.

#1 - Market research company founded in 1989 (I joined in 1990) and it still exists today. I left in 1994 when it was 40 employees. It is presently at 18 employees. It still pays the owners bills but toils in obscurity with no growth.

#2 - Franchise services company founded in 2004 (I joined on at the founding) and it still exists today as well. I left in 2009 and it was 3 employees. It is still 3 employees and much like company #1 it has virtually no growth.

While both companies are profitable, barely, they both suffer from what I call "zombie mode syndrome." They make enough money to stay afloat but without any organic growth they can't fund expansion nor attract investors. And for that, I believe they are failures.
Forrester CEO: “Nonsense” Like Foursquare Will Soon be Replaced
The car seat needs to be individually adjusted, especially for younger kids (different heights needs the straps in different slots, although the fine tuning can often be done on the spot).

And you're going to need every combination of ages, people have more than one child.

There are approximately 10 different car seat configurations for the various age ranges (5 actual car seats). And assuming up to 3 kids would require 1000 different cars.

There is rear facing (with 3 heights), front facing strapped (4 heights), front facing buckled, booster, and booster without back. (Although many car seats can handle 2 types in one seat. But it requires you to reinstall it.)
I wonder how effective donating to charity is on improving the survey quality.

You should have chosen an unbiased source to prove your point.

"The Interactive Advertising Bureau (IAB) is comprised of more than 500 leading media and technology companies that are responsible for selling 86% of online advertising in the United States."

Aside from anecdotal evidence (your returns of 15:1) I haven't found any long-term studies done by independent researchers that prove internet advertising is any more effective than other forms of advertising, if it's effective at all. The only real accomplishment internet advertisers can lay claim to is training the general population to never even glance at the left / right / top / bottom navs on a page.

In general, the poll results and comments in another recent thread on HN on ad blockers (http://news.ycombinator.com/item?id=3324709) seem to support my theories about how ineffective internet advertising is. I'd be interested in seeing some untainted long-term research on this subject.

Daily Mobile Minute #68: The numbers episode
This is at least partly a matter of retention. There was a study on giving algebra tests to adults, and one of the best predictors of performance was how much math the person had taken. So someone who had taken math through calculus did pretty well on the algebra test, regardless of age, while someone who had only taken through algebra had basically exponential decay from when they had taken it. (I can't think of where I saw this -- does anyone else know?)
So I would assume that Mr. Roach's degrees are in non-technical subjects, and that he likely didn't take anything higher than pre-calc.

Open source conflict-zone radio app Airtime gets 'pro' options
By the way, "beginners" wanting to get started building Ruby-based web applications should have a look at Serve (get-serve.com). It's not a framework per se, but if you're coming from PHP, it will probably get you started with the Ruby ecosystem pretty fast (and well), since it allows you to just create an .erb file and add inline code.

(Which is what most PHP people seem to want initially - you know, before that magic thing happens where they realize that real applications need structure.)

For peak times, I'm imagining 8-12 seater vehicles where people sit in pods facing outwards, with dividers that could be retracted if you were speaking with your partner in the same vehicle. Pick-up points would be very near to your home, and drop-off very near to your work. No parking to worry about. Something in between a regular driven commute and walking three blocks to wait for a bus.

Software would decide routes and timing to best service as many people as possible.
I have both an iPhone 3GS and a Galaxy S - I prefer my Android's OS and app ecosystem.

For the OS, I prefer Android because it is more flexible and smarter. Apps that are doing stuff in the background behave like expected, actually doing stuff in the background. The back button is standardized, apps on Android collaborate more because of the well designed intents system, I like my interactive backgrounds or screen widgets, I like my task manager, I like my Wifi tethering without paying a freaking tax for it, I love that you can install apps from outside the marketplace without a jailbreak, I love the way my contacts are fully synchronized with Google's Contacts, I love how Facebook adds new phone numbers and updates the pictures of my contacts list, I love how upload buttons in the browser are NOT disabled, I like the turn-by-turn directions of GMaps, I like the awesome/native integration with GMail, I like that I am allowed to have Flash on it (I rarely use it, keep it disabled, but it is useful when I need it) and I could go on and on.

As for the marketplace, I like how unrestricted it is. I have an app that blocks calls, SMS messages and deletes all logs of blacklisted phone numbers. This was the first app I installed on my Galaxy S since it is so useful to me. And when I tried it on the iPhone, apparently apps like iBlacklist need a jailbreak - I mean, WTF? That's not a smartphone.

The iPhone 3GS I bought because people like you claim it is so much better. I bought it without a contract so it was a lot more expensive than my legally unlocked Galaxy S purchased with a plan. I regret buying it.

Unfortunately there's a really loud minority of iPhone users that are recommending iPhones, getting really heated over Android. So here's what I suspect - I suspect that this is a side effect of buyer's remorse, trying to justify an investment that you know in your heart is a losing bet (pretty sure this syndrome has a name, but I don't know it).
Yes, I will take a look at the setuid part. Thank you. :)

Congrats on the getting the MVP out!

Criticism:
The problem you are trying to solve is the lack of quality in online surveys. The way to improve the quality of the surveys is by enabling users to chose a charity wich will receive 1$. This doesn't really make sense to me. Can you rpove there is any correlation between both of these two elements and how do you mesure quality?
This was originally about trading. Entrepreneurs are not traders, and while in a perfect world they would have a similar set of concerns, but generally not in today's world. (see HFT)

What your model of perceived value isn't accounting for are speculators who are in a market with no real vested interest in the product. The correct amount of speculation within a market can round out extremes but there is a balance. Free markets generally find the best prices for most things and works well in the majority of situations.
On the contrary, the guardians had to pay some amount if they let the AI out. The stakes varied greatly, but if I recall correctly Eliezer cashed in 3000 dollars (or something in that ballpark) from one guy.
He probably graduated before we had standardized tests.

This is actually a good argument in favor of standardized tests - make sure morons like Roach don't get to put things like "High School Graduate" on their resume.

Maybe this is a good thing if a more experienced pilot needs to 'hold the hand' of the other ofr some fine tuning manouvers, but when the commands are opposite from each other than it realy makes no sense that it decides to average them out and in doing so, basically respondes to none as desired (possibly having the operator use more force to get the desired response).

The analog stick seems much more reliable in this way, only one source of control of the aircraft, period.
Congrats on getting your MVP up and running. That's a big accomplishment.

However, you're at a point in your business's life where things might get dicey. I think you'll find that the business grows slower than you might hope, and no amount of coding will change that. For bootstrappers, it's just the way it goes. You're not going to spend $10,000 on ads, so you just have to do things the slow way (talking to bloggers, writing articles, posting on forums, etc, etc).

Your business will still require a lot of work from you, but at this stage it also requires time overall for people to hear about it, find it, leave, and come back later when they hear about it again. You have to give it time to grow and that means providing yourself with income. Maybe think about getting a job or doing freelancing. I know you said jobs require too much mental energy, but once the MVP is launched, you can dial back on the coding. You have to dial up the selling, but I've found this to be possible in parallel with a normal job, especially if selling doesn't involve phone calls and is just you emailing bloggers.

Anyways, I'm sure you'll find your way. Good luck!
Lissajous curves with Python
A handy snippet to visualize the Lissajous curves using python.
Ask HN: Making our email system faster.
I run a reasonably popular daily deals site (80k members) we were using a managed email provider previously, but over the last week, I decided to take a leap and code our own custom email system built ontop of SendGrid (shout out to SG, those guys are awesome). The difference about this new email system, is we're sending personalized emails to each subscriber, containing only the deals they want to see (we're not a yipit clone, or an aggregator, we run exclusive daily deals in different categories, users can now select which types of deals they wish to receive).

I'm not an amazing programmer, but I'm the lead on this site. Our generation of what to send and where to send it is fine (creating campaigns on the fly, queuing up emails to be sent) the issue arises when sending via SendGrid, currently, we're running a script that opens an SMTP connection to Send Grid, sends a batch of 100 emails (the sendgrid max per connection) and closes the SMTP connection (and repeat). This is pretty slow. We're at about 17 secs to generate and send the 100 email batch, I'm going to do some code optimization on the email generation, which will hopefully speed things up. I'm just wondering if anyone here knows of a good way to speed up our delivery. - As I mentioned, I'm an intermediate coder, what I've built thus far is in PHP/MySQL.

How to Design a Website With An Effective Copy
The Jones Company was founded at the turn of the last century. Unfortunately for them, their website looks like it was written at the same time. Being in business for decades is a testament to good business practices. However, The Jones Company needs to remember it’s a new century and their website should reflect that.
I feel like most people use this as a stop-gap for doing gzipping content to reduce bandwidth, but hopefully more people relying on nginx/apache to do the compression delivery will reduce the circa-2004 PHP mentality that started the practice.

Google Dart native on WebKit?
It's a bit too great leap of an analogy from bacteria to AI.
He panicked. What's there not to understand?
I like the idea, but I believe there are some issues.

PRICING
1) 1,25 $ is a lot of money for one (1) completed survey.
2) What prevents a company from doing this themselves (is your added value worth 0.25 $ per survey?)

SAMPLE
1) Charities are arguably not the best motivator for people.
2) In a world focused on the right metrics, your surveys automatically incorporate a bias into the results by only selecting those people who care about charity (to put it very blunt and stereotypical, you will only get tree hugging hippies). Same goes for prizes, but a prize is less about the core identity of your respondent (not a belief).

PITCH VIDEO
1) I felt a world-changing idea when you talked about "in person", was kind of disappointed when I realized it's still a survey with a different incentive
2) Half of the people a survey got mailed to don't respond. That's not a disadvantage, it's an awesome conversion rate.
3) I can't find any information except for that video (maybe a use case).
4) I don't really see a benefit for me as a user. Let's say deliverables: will you give me an SPSS database, a report, an analysis, can I import it in excel?, will it even have forms or is it just a way to give an incentive. Lot's of unanswered questions.

PERSONAL
1) Love the chat box and the 'I'm a real person and founder' part. Not sure how long you will keep it up :).
2) I like that you as a person are part of the brand, something very potent.
I'm all for driverless transportation, but let's face some important facts.

Why didn't we _already_ remove the drivers on trains? The train/metro system is basically a closed system which is much easier to control than a car in traffic. This is a genuine question: why? It looks like a much easier to solve problem.

Second problem will be certainly be fuel. A 20x increase in utilization means at least a 20x increase in fuel, unless the car is _transporting_ something at all times (which basically means car sharing). Sending your car home empty is crazy in terms of fuel.

Legislation is also going to be a hell of a problem, at least in EU.
Common SSD pitfalls and how I addressed them
I would assume that Mr. Roach's degrees are in non-technical subjects

Mr. Roach's degrees are now known to be in education.

http://news.ycombinator.com/item?id=3326293

"Roach, the father of five children and grandfather of two, was a teacher, counselor and coach in Orange County for 14 years. He was first elected to the board in 1998 and has been reelected three times. A resident of Orange County for three decades, he has a bachelor of science degree in education and two masters degrees: in education and educational psychology. He has trained over 18,000 educators in classroom management and course delivery skills in six eastern states over the last 25 years."

I will note for the record that a proper, accredited degree program in educational psychology ought to have a statistics for psychology class included that would provide a mathematics refresher to postgraduate students who don't test out of that course. If not, the degree program was appallingly bad.
Consider the positive impact of having a weight on a string flailing around in a cockpit when the shit hit the fan. The articificial horizon works on this same principle, but pilots are known to ignore it anyway. The whole point of instrument flying is to se aside your senses and common sense and look at your instruments.

One of the problems was that the plane was unexpectedly stable during the stall so the pilots might have dismissed the stall warnings as disconnected from reality.
It's been done before. From the excellent article "The Turn":

> Pilots, too, have relied on pendulums. It is said that an airliner inbound to New York in the 1950s lost all its gyroscopes in heavy weather over Block Island. The captain was a wise old man who had risen with the airlines from the earliest airmail days and was approaching retirement. A lesser pilot might have fallen for the trap of intuition. But the captain simply took out his pocket watch, dangled it from its chain, and began to swing it toward the instrument panel. Flying by the pendulum and the compass, he proceeded the length of Long Island in the clouds. After breaking into the clear near the airport, he landed and wished his passengers a good day.

(the entire article is really worth reading: http://www.theatlantic.com/past/docs/unbound/langew/turn.htm)

But in this case the pilots didn't even need to do that. Their gyros were working correctly, so they had an artificial horizon right in front of them. The attitude of the plane was known. They even recovered their airspeed indicator after 30s (the second one after a minute)! All that was needed was for the pilot to stop pulling on the stick…

I agree with you whole-heartedly on these patents. But... I think the point that you're missing is that the Supreme Court is like a meta-court. You don't go there to appeal your case, you go there to appeal specific decisions and interpretations of the law.

IMO, from a lawyers vantage point, what is the difference between a patent covering a software method (like encoding music) and a medical procedure? There really isn't any. Both are equally offensive to the folks who practice in these fields -- I have yet to meet a programmer in favor of software patents, and I'm sure doctors will feel the same way.

The problem is that the law as written is that software patents ARE ok. As long as that is true, how could any judge make a case that medical procedures are not?
