Start looking into bash scripting, for one. Learning a scripting language like python or perl can do a lot of the same things and is valuable in other ways.

To your comment of looking like just one thing is happening, that is understandable to the untrained mind. Let's take an example where I want to delete all the .bak copies of my old configuration files. To do this I would enter the directory and simply type:

rm *.bak

It's one command, but the star is expanding it to match every file that has a .bak ending. One command line entry, many executions of the 'rm' command.

Yes, context and a trained eye are everything. I like to think that working on the command line is one of many styles of working. It works very well for me in some situations, so I suggest to others to try it out and see if it would fit their needs as well.

He missed an opportunity to make another point here. Surely it isn't easy for a large company to behave like a small one or that they move slowly. However, being a large, seasoned company with all kinds of bureaucracy should at least buy you the ability to set realistic deadlines and meet them. Announcing a critical update to your platform and then failing to deliver it four months late is a small-company mistake, and mistake is being really generous.

It'd be nice of Facebook was so focused on speed - the like button slows down every webpage I've ever put it on dramatically.
Ask HN: Are QR-Codes used by customers in Europe/America?
I have seen a lot of buz in the last few months around QR-Codes. At the moment I am trying to find out if it's worth to add QR-Codes to advertisments. Advertisment-Space is very expensive. I have to choose what to put on the ad. Something that is not used by customers or confuses them is not what I want to add onto it.

Are there any analysis on the usage of QR-Codes? How many users do actually scan those codes? What target audience fits best?

From my gut I would say: If you have a target audience that is male, 16-26 and is very IT-focused, it would be okay to add those codes. But is this the truth? I have seen QR Codes on Ads for non alcoholic drinks that target women, too. Do they actually use them? Or do they add enough value for my brand to be there even if nobody will scan them?
Notifications are a bit of a problem with web apps. It's much easier to do everything client side on a mobile device and I haven't figured out how to elegantly implement a notification system on the server side. I could potentially do everything by email but that brings a whole bunch of other headaches with it if I don't want to be blacklisted as a spammer. Currently I'm looking at appcelerator and adobe air to make the app more accessible to a wider audience but that's a little ways away.
The guy does maintain a very popular iOS lib:

Maybe he inherited the project from the original authors with the arrangement that he'd maintain it as open source, but was indelicate in how he modified the license file.
Right... because Bill Gates didn't make billions from the education market.

You go build a company around giving things to the education market for free and I'll build a company around selling things to the education market, and we'll see whose company is better off in five years and whose customers are better off in five years.

PEGs backtrack to handle multiple alternatives, and can bound their parsing time to linear by memoizing; ANTLR generates LL(*) parsers (despite its name!) which use a token-lookahead mechanism to bound their parsing time to linear (and, incidentally, run much faster).
Survery: How do you search for solutions for your bugs?
This.

The very best gifts are the ones that you didn't know you wanted until you received one, and thereafter you discover that you can no longer live without them. My first microwave was a gift from my sister, and it followed this pattern. I scoffed at them as being convenient but taking up counter space for a function that my stove could accomplish already. Soon after she gave me one, I started wondering how I lived without it.

Great products fit this mold exactly. People scoff until they try it, then they become attached to it, and finally dependent upon it.
This is a really exciting announcement! Education is probably the most important factor in maintaining long-term competitiveness and the American system is in desperate need of improvement. That said, the hurdles in this area are overwhelming. To name a few:

-Layer upon layer of bureaucracy (states, counties, districts, individual school administrators)

-Teachers that are reluctant to adopt new technology

-Students that are difficult to motivate

I have a ton of respect for anyone even trying to take on this challenge.
Ok . I have a lot of respect for that approach.
Yeah, this recruitment thing he laid out is illegal on several dimensions.

1. employer is obligated to advertise broadly enough to generate a diverse applicant pool (for protected classes).
2. personal reference is prohibited along similar lines.

IMPORTANT: by the sheer fact of your pool not being diverse, you have liability! does not matter if you treat every protected class applicant really well! The NON-DIVERSE POOL ALONE creates a legal liability.

This is also illustrative because VC's often say the'll help company management with operational issues, but because VC's are so sheltered (don't have to hire a lot) they don't know these basic issues.

Any company CEO worth his salt is very sensitive to "job applicant pool" issues, and funny that the operations value add from a VC is going to lead some poor CEO into a lawsuit!!

You're conflating the implementation of an environment with the value of the environment itself. Did you read the C code? It is terribly difficult to follow, does not follow C formatting idioms, and makes frequent use of macros that further obfuscate what is going on. Example:

#define DECLG V*sv=VAV(self);A gs=sv->g; \
AF g1=gs?VAV(gs)->f1:0,g2=gs?VAV(gs)->f2:0

Judging the quality of this code says nothing about the language and environment that this code provides.

I personally had the iPad grew on me more and more to the point I rarely pull my MacBookPro when at home now. As a nerd it really helps me cut off steam and saves me from burning out. Using the iPad triggers some kind of zen moment in my day where I can contemplate, learn and create (I draw) stresslessly.

It happens that my use case of the iPad is actually the opposite of my iPhone where I'm constantly diverted by various events and notifications. It's not that the iPad is disconnected but it's more of the flowing kind and less of the pinging kind.
My experience has been that many applications (web apps in particular) use a relational database to break up documents into an SQL schema so they can be indexed, then assemble them again when needed. Mongo really ratchets down the friction on that operation. Instead of spending time building a schema and writing lots and lots of insert and update statements, you just build a JSON object and send it over.
I have never uset Github and I must confess that I didn't understand what happened here ):
Yeah, yeah, yeah, tell it to the EEOC.

The applicant pool requirement upsets a lot of people (like how the hell can i control who applies?!), but it's the reality of modern HR.

Good question but I think they will always have the 'cool' crowd simply because allowing a weary stanger to stay in your apartment is inherently a cool thing to do.

Things Your Cat Really Needs: RFID Cat Flap and RFID Feeder
This article highlights the insane legislation in the US by way of contrast to these other countries.

FTA: "A 25-year-old Sydney man from Eastwood was sentenced to eight years in 2010 on multiple charges including three counts of having sex with a child, while Victorian Bryan Cooper is serving seven years for procuring boys for sex," said the paper's report. "Sydney man David Anthony Hudson, 40, from Russell Lea, was jailed for his role in an international child sex tourism ring and is spending a minimum five years and seven months in jail for offenses against a Thai teenager… George Iliakis, a former teacher from exclusive Brighton Grammar in Melbourne, sent videos and pictures of young boys to other members of the ring, which at its height had 70,000 members. Iliakis, who is serving a minimum two-year sentence, handcuffed and gagged boys before photographing them for his sexual gratification."

I was like, "Only eight years for actually having sex w/ three kids? Really?!?" In the US, people merely convicted of possession of child porn can get way more than that.

I personally don't buy into the "demand" argument which drives possession-only legislation. I'm all for throwing the book at folks who abuse real kids, but I think locking people up for collections of bits on their hard drives is pretty lame and a waste of resources.

On the one hand, I'm thrilled that real predators were sentenced to jail time. However, part of me cringes at the notion that boylover.net was shut down, if only for free speech reasons (which I know is handled differently in other countries). As hideous at the topics likely discussed on the site may be, I'm guessing the majority of the site users were rather benign and society was better off with them having a place to gather online.
You can also hook into the kickback schemes by partnering with major reward programs like Amex Membership Rewards. Or work with state governments to have a voucher program like what Ireland has for BnBs.

It seems Imagine K12 will/has solved the classic chicken-and-egg problem with education startups. I've been asking on how to get traction at schools online in different communities for years when I was working on a side project in this area. It's virtually impossible to sell to school districts, and unless pioneering teachers who are savvy enough to use something like Google Apps for their classrooms and see your product in the Marketplace or look for solutions on their own time while somehow fitting it in their already tight classroom curriculum and time budget, you have no way to gain traction from authority figures in the school system.

Enterprising students are basically they only way I've found that educational startups/sites can get active users to join on.

It sounds like it has the same disadvantages as a gas turbine, then. It would have been helpful if they had contrasted it to a gas turbine instead of to a piston engine. Theoretically, a gas turbine has huge advantages over a normal ICE. Yet, there aren't any cars powered by gas turbines...
You can't have an absolute right to something that requires someone else to provide a service for you (remember that rights are inalienable, so you have them no matter how much money you have.) Such an obligation would essentially make the provider a slave to some extent (this effect can be very small for a given person, but the principle is the same: if you have to do something you don't need or want to do otherwise, and you're not even getting paid to do it, what does that make you?)

Rights only make sense when they're defined as legal prohibitions on action. Rights come from our nature as human beings; without the protection that they provide, we wouldn't be able to do all the things that we need to do to flourish (a concept that includes more than just biological survival).

I'm bias as i'm in competition with these guys although we're trying to make something more social with a proper backend for earning badges, no referrals, twitter support and other cool things.

But this sounds worse for the Merchant and user.
User: Has to sort out a rebate for something they already paid for, has to refer friends and get them to buy to earn.

Merchant: The user has no inventive to return as you're giving them money off.

If a user actually likes a product and if worth the merchants time and money giving them a reward like a coupon (25% off or a free item when they buy something else would be far more powerful) In my opinion at least.

I've been working on this since mid last year and am happy with our implementation but this shows what a big market this is going to be, the best of luck to them, although we are doing similar things I don't think we're close to the same.

Let's be honest it's going to be rare that anyone will earn a rebate so giving them a code to return would mean they earn something and the merchant has the hook.
They tried to set a realistic deadline - they internally estimated they'd have it out in January, but were usually careful to pad that out to "early 2011" or "in the coming months" in public. Unfortunately they slipped a couple times.
Maybe it's different in the US, but as a Finn I don't think "end up drinking more" is good since people generally end up drinking quite enough without any financial help.
I expect basic education to stay within the realm of government and free. Public giving up education to private/corporate sector is a recipe for disaster.

How technology can help government improve the quality, and how technology can keep the education free for the masses, is another thing.
Have you tried using their async API?
Quality isn't the issue for most subjects. There are plenty of free and cheap textbooks with perfectly fine quality.

For example, when I took thermodynamics in college (in 2001), I used a thermo book from the early 70's which cost me $8 on eBay (as opposed to the modern version which cost $100). I also skipped purchasing many books entirely, and just used free materials online, including this newfangled site called wikipedia.

Agency costs and are the issue. The people assigning books don't have to pay the cost of using them, so they have no incentive to select based on price. Further, it's very difficult for students to use substitutes - if the professor assigns problems 1-10 from the book, it doesn't matter how good the material in your cheaper substitute is.

If you want to crack this nut, focus on problem sets, not textbooks.

Taxation is not the same thing as "forced labor" or "command economics".
I upvoted this because it's completely accurate, but at the same time reminds me of some of the things I don't like about HN. HN has a much higher tolerance for people constantly submitting things from their blogs for self promotion. If a person submits something self promotional on reddit and expects to escape sharp criticism from the community, they better acknowledge that they are being self promotional, and be awfully humble about it. Here, it seems to me that everyone acknowledges that everyone else is out to make a buck and deals with it.

tl;dr - HN has more tolerance for shameless self promotion than reddit as well as fewer trolls.
It looks like they wanted to simply flatten the Chrome logo, but the gradients radically change it from a sphere with a central "node" facing us to an unappealing doughnut shape with some sort of "nipple" in the center.

And while the gloss of the original may have been a bit much, it allowed the colors to be a bit more vibrant. Now they've been diluted down to these pastel colors which are also very unappealing.

The original Chrome logo isn't perfect, it looks a little too slick, but it was the best visual design to come out of google (besides some amazing google doodles of course) and now it seems that they've dumbed it down to match the more simple and design-agnostic approach that is typical for google.
The colors need a bit less saturation to really become subtle, they're a bit too bright and overly-chromatic. I like the concept, but the execution is poor.
The economy of scale here will be huge - if the founders of Imagine K12 build vertical expertise in promoting education startups (i.e. connections with schools, VCs who invest in education) it will be a lot easier for startups to do customer development and build/implement cool ideas. Our education system will benefit big-time.
Same here. Thanks for the links. I am specifically interesting in learning Ruby THEN Rails. The other way feels backwards, but that might just be me.

I digress-I have a basic, I mean real basic question-what is a recommended environment to start coding ruby projects? I use XAMPP and Aptana for my front end coding (CSS/HTML) and then render in browser. How do I do replicate that work flow with Ruby source (and integrate it with my front-end code)?

Lame, I know. But hey stupid questions are the one's you don't ask.

UPDATE: rubykoans answered my editor question. Ruby resources still appreciated!
Using data as a competitive advantage isn't a new thing, Tesco and Amazon largely built their success on their operational data analysis and eBay didn't fall to fraud like their competitors because they had better fraud detection algorithms.

However I think it's becoming much more common, most non-competitive industries often have ignored data analysis as a method for competing, hence it creates an opportunity for startups to disrupt stagnant industries.

SXSW By The Numbers: iOS, Foursquare And GroupMe Emerge Victorious
I'm trying to figure out what is so startling about this, actually. The { function just seems to return the element at the given index, or if you pass in a collection of indices, maps that operation onto the collection. That is convenient operator overloading but not mind-blowing.
The methodology looks decent. However, apart from the "does this use the fastest JavaScript" question, which the author discusses, I have two questions that I could not see addressed:

- were the web views for both devices of equal size?

- did the two devices get served the same content?

The first one probably would not make much of a difference, but the latter definitely can make a huge difference.

Oh, and the title is somewhat incorrect; this data shows that Android load speed is 50% higher. That makes its page load time 33% shorter.

This was interesting to try as someone who's never touched ruby before, it begins seemingly simple but gets quite complex. Does this really target beginners, or am I an idiot?
So IE6 still accounts for about 1 million monthly page views on our site...about 1.5% of the traffic.
Yesterday we took the plunge and decided to display an eyesore of a box on every page on our site if you surf to it with ie6.

Example of message: http://www.pinkbike.com/photo/6305769/

Imagine if many sites did this to spur the upgrade process. I'm really curious to see the results of this...will traffic plunge by 1.5% or will the usage of ie6 switch to other browsers. Note: no ie9 upgrade choice.
Actually, it's statistically indistinguishable, according to Google.

I should also add. Technology is driven by people so it matters how they use it to the advantage of all and not just some. When technology helps people, we generally mean to say that people are helping people. I am not being altruistic here but there are things which should be free and available to all equally and education is one of that.
