That article keeps mentioning the performance drawbacks of checking for errors, but I really can't imagine error checking to have any noticeable performance impact at all, unless you're going to the server just to validate input prior to sending. Why treat it as a serious consideration? Seems like that will just mislead inexperienced JS devs.

To be fair (as the guy who did the article), I didn't choose the headline. The article isn't really about growth hacking, it's about a better way of thinking about marketing--which growth hackers are one example of.

I could be ok with this, but there is a significant cost associated with it. You can already do this through an FFL, but it generally ends up costing $25-$35 and most people don't want to do that.

If you offer this as a service by the police, then it cost all taxpayers. I'd personally be ok with it, but I suspect that many people will balk at it. They'd be happy to pay for the "gun control" that consists of not allowing guns to be sold or simply taken away from people, but not as excited about paying to allow us to sell our guns to other people more safely.

Maybe this is something that could be solved by private industry, but someone would have to find a way to charge less to do it. FWIW, this intermediary service could be useful for more than just guns. People get robbed buying things like laptops on Craigslist all the time. Maybe you can help (i wanted to say solve, but i'll be realistic and say improve) 2 different areas at once.

I, for one, am not worried; especially b/c "true innovation" is an entirely subjective quality, and even if
we could agree on a comprehensive definition agreeable to all camps, the effect of innovation is not necessarily salutary. I think it's important to point out that
creativity, 'constructive' engineering endeavors included, is literally destructive. You understand probably better than I that nothing that gets designed today by a reputable engineer is done so w/o giving consideration
to its ecological impact. From my perspective, this is where true innovation needs to start, in cultivating a deep understanding of how we fit into the earth's ECOSYSTEM and cultivating technologically appropriate responses to the same.

On a side note, I also think you highly underestimate the technological advances that continue to be made under the infrastructural hood of the internet, b/c it's almost completely transparent. iPhone apps and websites in and of themselves may not be a big deal, but the growing scale of digital distribution channels and the level and scope of our interconnectedness certainly is. Not to mention, managing this growth in a way that is environmentally sustainable? Not a trivial engineering problem, and, in my estimation one of pressing concern...

We don't. Data points (or actions as we say on the about page) correlate directly with the amount of revenue we make. 85-90% of all data points are paid for by our customers. It's how we make money: http://mixpanel.com/pricing

It actually does a better job correlating with our growth than purely the number of customers we have. We've also been public about that.
I totally agree as such. I certainly don't think Python has a particularly good solution, just the best current practical solution. I mean it's pretty much an accident of history the python became a popular language for numerics and it's certainly not what it was designed for.

I'm following Numba and Blaze with interest and honestly consider Julia the most exciting new language out there. But until they reach a point where they are useable for me I'll keep using python and the incredibly powerful, if slightly kludgy, solutions it offers.

Maybe you've been subjected to more complete DLP systems than I have, but email "within the organization" is not and never will be "secure".

Every time I've seen customer demographic data emailed (although admittedly this hasn't been in the medical field), both the sender and the receiver have been employees (including myself) who weren't entitled to see that data. Organizations need to find more appropriate ways to collaborate, which don't needlessly expand the pool of people with access to sensitive data.

You seem to trust a pool of 100 people, even if they have acronyms following their names, more than you trust a search engine, to not share data in legally negligent ways. That seems ill-advised to me. If the Googlebot were generating lawsuits for breach of privacy we would have heard about them.

I don't think this sensitive customer data should be in Gmail, because I don't think it should be in any email system period.

It seems like one takeaway is that a significant portion of people will just pay the default as stated, even if given a choice. I think people just have a hard time deciding what something is actually worth, so they'll take whatever advice is given. So, when pricing your products, if you're wondering if you should charge more, the default answer should be "Yes"

I think theres a difference between advertising or celebrating "bullshit" metrics and actually using them.

For our most recent press releases, we reported many of these "bullshit" metrics because thats what gets acclaim and attracts attention to help the company gain the necessary notoriety to thrive. Internally, we still use real, actionable metrics to drive our development. We just don't report them to outsiders because its either sensitive information and likely uninteresting outside of the context modeling or users experience.

That's a good point, although if you are willing to relocate to a hot spot, you won't have too much trouble picking up a next job when the first fails. I get asked multiple times per week if I know any developers looking for work here in San Francisco.

It's also much easier to get into a company if you can talk to the people working there in person regularly rather than doing remote interviews and phone conferences. A couple pair programming sessions, hackathons, or fun projects together and you might be in the door without any of the usual suffering. Although lack of process like that is part of smaller startups as well.
People tend to be polite, especially when it comes to expressing thanks for a gift.

It is so incredibly depressing to watch Amazon blow an amazing opportunity with shitty software. They can outsell anyone, but the Kindle Fire OS work is dreadful -- if they could manage to build a competitive UI then they could probably march way ahead of Android-proper on browser usage metrics (as well as whatever they use internally to measure engagement). They seem to spend a huge amount on Kindle Fire, they're competitive with Barnes & Noble but not Google or Apple.

I'm betting that most of the Kindle Fires that Amazon do sell end up "in desk drawers" and don't drive many further sales for them -- and it's entirely because the software is so awkward to use (the first Kindle Fire was pretty clunky in industrial design, and the new ones aren't wonderful but at least they're competitive excepting the hard-to-use power switch).
Twitter Bootstrap jQuery Table of Contents Plugin
I was with you until you said "This platform cult is pretty meaningless to me." Actually the platform wars are quite meaningful insofar as they represent large-scale manipulation of consumers. Both Apple and Google are playing the following game: hey consumer, here's a shiny device, it's pretty cheap and then we lock you into a 2-year contract, meanwhile you acquire apps that can only be run an iPhone, and now even if you wanted to go to Android, you are faced with the prospect of ditching your entire software library (or vice-versa). It's called lock-in and it's a long-term manipulation of a market. I'm sure that both Apple and Google rationalize that it's a way to recoup R&D costs, and that's true enough, but it's a sneaky way to do it.

There's also the not insignificant problem of app security. Not so long ago there was a news item about the FB native app accessing contacts and uploading them to FB servers. The web app cannot do that, and that's a Good Thing.

There's also another reason why HTML5 apps are better than native: they are composable. There isn't much out there other than search engines that takes advantage of this fact, but webapps can be composed, parsed, and otherwise uniformly manipulated in useful and interesting ways. Android and iOS do indeed offer some integration points for their native apps, but nowhere near at the level that the web allows today.

Blowfish or twofish wouldn't hurt. But I'd be happy with AES, too bad none of my devices have hardware acceleration for it.

The fact that it was proposed in 2008 is quite telling by itself. And when intel introduced it it was in their high-end product lines, to find a processor where AES-NI is less needed would be a challenge.

A suitable integrated GPU would penetrate the market much better and ultimately support products which today use the atom processor. The very same product segment where you barely can use encryption on today (in contrast to a i7 which saturates a fast ssd without breaking a sweat in AES-encryption throughput - without hardware acceleration).

A similar solution would also most likely allow me to encrypt files on my phone without a large impact, even if the manufacturer couldn't care less about security features.
shut up and take my money ! :)
I looked at this earlier this year. Lack of API access means that we cannot build an application similar to Simple in the UK. I e-mailed several banks and most of them did not reply.
> HTML/CSS/JS is exceptionally good at building user interfaces

Only if your background is HTML/CSS/JS. If you have no web background, figuring out the idiosyncrasies of CSS and JS, while very doable, is still very time-consuming. I can't imagine it being any faster than someone going the native route assuming they do not have an existing web skillset to leverage.
I would assume realtime editing will be supported by the browser developer tools fairly soon.
What's cool is that feature was completely intuitive and you didn't need to point it out. Again, a little thing, but the little bit of delight users experience when they "discover" these types of features goes a long way.
Why would they put in the chip if it didn't have an antenna?

I think T-Mobile is selling their HSPA+ as "4G", even though it's not using LTE yet. So it's not that no GSM carriers would advertise the phone as "4G".

Perhaps they designed and/or manufactured the circuit boards before they had the frequencies all sorted out. Perhaps they need the chip in there for patent licensing reasons.

Some gun control stats
A lot of people are posting about gun control given the recent events in the US. I thought some stats would be interesting. When considering whether gun control is the right approach to curb these atrocities we would benefit from examining these numbers (and others) to help aid (or disprove) our arguments.

A 2007 survey has the US gun ownership rates at 88.8 per 100 residents. They rank #1 in the world, with Serbia ranking #2 (58.2 guns). Canada has 30.8 guns / 100 residents.

The US also ranks quite high in firearm-related death rates. On average 9 per 100,000 citizens per year, 3 of which are homicides. Canada is about half of that at 4.8 (of which only 0.76 are homicides). FYI, the highest in this category is El Salvador with 50 and a few other central american countries (jamaica, honduras, guatemala) not far behind.

In terms of school shootings, the statistics are quite well documented. The US actually has its own "school shootings" wikipedia page if you're interested: http://en.wikipedia.org/wiki/List_of_school_shootings_in_the_United_States - European, Canadian, etc are referenced here: http://en.wikipedia.org/wiki/School_shooting

First of all, they are not saying there is one true metric that rules them all. They said each site will have one key metric, which makes a lot of sense. Each site will most want to measure how users engage with their domain. The example mixpanel offers is that Instagram wants to know how many users uploaded a photo. This matters way more than pageviews, etc. It tells you something about user engagement.

The bigger issue I see in your comment is that sites at different stages in their lifecycle will want to measure different things. Customer lifetime value is the most important number for a mature business but early stage startups are nowhere near getting a realistic number for customer lifetime value. If I am the founder of a startup I want detailed knowledge of how users are interacting with the product I created to address a problem domain. I can get that info immediately after I start acquiring users, well before I have an idea of whether I have a viable business and what my customer lifetime value is going to be.
I'm lousy at the maker thing.

But I try to select gifts that the recipients will find useful. Even if it's still an act of consumption, it might as well be one that meets a need -- a better carving knife or a nice pen, rather than a solar-powered hand-waving queen or a novelty toy.

Or, failing that, food and drink.

Yes, it's necessary to pay attention in order to figure out what the recipient perceives a need for. But having a close enough social relationship to be able to do that is, in my view, a necessary prerequisite for gift-giving.

NB: I think the take-away from Monbiot's article, for HN readers, is this: try to make something that people need, not just something they want (for 5 minutes).

That's interesting. I assumed that the purpose of the sale was to increase the game's publicity/popularity, an attempt to get it into more peoples hands and make it into a household name. But if it's just an expansion pack, then you're really only selling to existing customers, not expanding the customer base.
The real reason is that they went with the Qualcomm S4 SoC, which has an LTE modem on-die. It's likely that it would be too expensive to have Qualcomm manufacturer an LTE-less chip for one device.

Well, mainly because I agreed with you and didn't feel like wasting much time saying so. I was also frustrated with so many people in this thread focusing on the guessing method and acting like a 3% success rate was high. That annoyed me since, as I said, first class captchas have been attacked with ~50% success rate in studies.

My experience with an unknown site has differed from yours dramatically. I have a small, custom site that I share with less than 10 friends and I have had to progressively step up the security (none -> captchas -> passwords) because it has been attacked with thousands of spam messages on several occasions.
Real shame, is there a blog anywhere about the setting up of Simple? The idea is brilliant.
