Are you overriding the back button to show an offer when clicked? Or do you show the offer before the click by tracking the mouse position?
> it makes the public safety officials look impotent in the face of real threats.

They largely are. It's incredibly difficult to stop crimes before they're committed, and prior to any terrorist mania it was generally considered to be outside the scope of police work. Mainly because it requires a security apparatus, and authority, that is in direct conflict with an open democratic society.

The Freedom of ATV Exploration in Vail
With the wind at your back, the pristine Colorado countryside before you, and four tires with a rumbling engine beneath you, it’s practically impossible not to bask in the weightless, liberating sense of freedom brought about by a solo ATV ride. Vail ATV rentals allow you to rent your own ATV and explore the trails on your own, granting you the flexibility to choose your own adventure as you rove through the seemingly endless wooded routes.

You’ll have everything you need before you depart, including safety instructions and a map of all the ATV trails in the area. ATVs are rented by the hour, so be sure to give yourself enough time to soak in all of the unbridled, pure freedom that you can manage. Vail ATV rentals can help you prepare for and thoroughly enjoy the one-of-a-kind feeling of solo ATV exploration.
Both Moo and Moose generated inlined versions of their constructors and accessors that mean that there's only a single method call being involved.

As such, runtime is just as fast as any other perl code that uses accessor methods rather than poking into its own internals.

Plus, of course, once you've got a Devel::NYTProf profile showing that a particular accessor is a hot spot, you can still poke into your own internals for that particular purpose to resolve the bottleneck.

So, no, not really; generally you only pay a cost for the pieces of cleverness that you actually use, especially given the existence of Moo for fast-startup code where you don't need the MOP.
The demo is not really doing anything for me... I get the welcome pop-up when I enter the site, but nothing has come up when I go to leave the site (whether I have clicked on anything or not). Is it supposed to bring up an alert when I go to leave?

Side note: I am not sure how I feel about these techniques. I remember something similar on hobbyking, where if you left a page open for too long a pop up would come up offering you a discount for the item. Once I figured out it did this, I would go around leaving pages open hoping to get discounts. It was annoying, and I would refuse to pay full price after I saw this in action, even when it stopped making me offers. Be careful when overly gaming your customers.
Couldn't agree more.

I'm also a Mac Developer, my app is Codebug (http://codebugapp.com/) an Xdebug client for Mac. I created this app in 2012 while I was learning Objective-C/Cocoa, and it's been a very cool steady growing since day one.

Specially the increase your price part. I actually added a bunch of new features and increased the price. Guess what ? The sales didn't drop at all, matter of fact they increased. I get a lot more top-quality users and people who actually engage with the app and are prone to spread the word. Also, I'm selling it from my own website, not from App Store. Sorry Apple, I already pay you $99 dollars a year for your dev program. Not going to share 30% of my profits with you :P

iOS or Mobile app doesn't appeal me at all from an indie dev perspective. Everything pretty much has been done, and there's this stigma of not charging your app of what it's really worth. Everyone is doing Free, In-app or 0.99 cents apps. Screw that, I need to put food on the table.

TL;DR: Make a good product, keep improving it, price it right and you will succeed in the long run.
Of course not. I am a Buffalo Bills fan. After the early 90s, my hopes have been dashed repeatedly, to no end. The coming season will be no different.

Report to Oblast 37N. We have made you an appointment with the Education Corps.
Thanks! Conversion rates for campaigns depend on the type of site, traffic quality, the targetting options you choose and ofcourse - banners and offers. But in general - they are lower for campaigns targeted to visitors that don't engage and want to leave straight away (0.1-2%), and higher when users have spent some time on the site, and really high (10+%), when campaigns are shown to visitors who started purchase process but for some reason decided to leave.
> my eventual girlfriend had terrible pictures - the grainy, multiple-people-in-the-background sort you're never supposed to put on a dating site.

This is not what people mean when they say someone looks terrible in their pictures.

The point of the experiment is to withhold information about whether someone is physically attract, not about whether they have good photography skills. The only reason to avoid putting up grainy pictures is because people will assume you're not good looking and are trying to disguise this fact.
OKCupid Falsely Matched Users in the Name of Web Science
The numbers don't add up. To make $125,000 in a 12 day period, you're making $12,500 / day average. Assuming you're receiving average $1CPM that means 12.5 million pageviews / day. $1CPM seems pretty hard to do on social network traffic unless you're putting images right next to the advertising links, or some other practice that breaks Adsense TOS.

If you're actually doing those sort of numbers and can get them consistently, you should really be trying to get a premium adsense account. You'll get higher CPM's, a Google rep that helps you optimize adsense, and most importantly you'll get the benefit of a doubt (and some other goodies if I remember correctly).
If the source to the method being called is not available, then it's certainly possible for the compiler not to be able to tell how a pointer passed to that method might be used.

I noticed django-sendfile on the list but I personally prefer https://github.com/benoitbryon/django-downloadview now. Until very recently, django-sendfile didn't support python3. django-downloadview also works with storages, and allows you to serve files with the development server based on rules.

This is pretty simple to do on your own. And although I appreciate the idea of charging folks who don't want the hassle of building something themselves, some might want more control: http://tonylea.com/go/examples/jquery-exit-popup/#
Indeed it was a very ... unbalanced piece from someone who has only visited Russia once in two decades (by his own admission).

Basically a self-proclaimed "serial entrepreneur" who has little understanding or insight on the subject is exploiting a politically/ emotionally charged topic for his own questionable gain. Why read this crap?

I'm not sure what you mean. Are you suggesting they're not actually 3d printed toys?
So in principle, it's doing the same thing as:

$ curl http://get.example.io | sh

which we all know is bad. But in this case, it's hidden deep enough that most people don't even know it's happening.
> I found a similar thing: once they got to the date, they had a good time more or less regardless of how good-looking their partner was. Here’s the female side of the experience (the male is very similar).

I'm skeptical it was similar, at least if you were to measure the thing that actually matters: whether or not the person wants to go on a second date. ("Did you have a good time" is probably equating to "Did the person avoid doing something terrible" in the survey.)

It's ludicrous on its face to think that men, if they choose a blind date partner based on conversations and profiles, will want to go on a second date just as often with a beautiful woman as with a plain woman.
I tried using Google login, and it wouldn't proceed unless I created a Google Plus profile.
Seems like actions were designed to encapsulate update logic that doesn't belong in the store (e.g. update ordering when multiple stores are involved). A pubsub event queue wouldn't make this very easy.

It simply doesn't apply. A black swan is a rare event that is almost certain to happen (or at least one of them will) that will destroy vast amounts of wealth. Because they are so rare and it's so hard to predict which one will actually happen, people don't prepare for them so they do an incredible amount of damage to the financial system.

The idea is orthogonal to seed round investing.

Thank you for the feedback! I guess we need to improve demo site, so it is more clear. Our idea in demo page was to show different kind of targeting examples while simulating a purchase process. And the Exit example is in further steps.
About overly gaming customers - sure, based on our experience we suggest our client suitable campaign ideas, and it actually does need always to be a discount, it can be some ongoing promotion or reminder about some specific feature.
Sort-of. That has the additional non-malicious risks. A broken connection turns "rm -r /var/lib/cool/place" into "rm -r /var/" and the shell processes that.
How did you calculate that 250ms latency number?
For Leiningen at least the goal is eventually to be able to flip a switch that will make it refuse to operate in the presence of unsigned dependencies. We're still a ways away from that becoming a reality, but the default is already to refuse to deploy new libraries without an accompanying signature.

Edit: of course, the question of how to determine which keys to trust is still pretty difficult, especially in the larger Java world. The community of Clojure authors is still small enough that a web of trust could still be established face-to-face at conferences that could cover a majority of authors.

The situation around Central is quite regrettable though.
When your immediate response to a post pointing out your non-constructive attitude is to say "Oh excuse me your highness." followed by "Blow me", I'd say the project leader's initial estimation of how constructive you were intending to be was pretty accurate.
You know at this point I would be shocked and surprised if they don't invoke "terror fears" one every single incident. Someone forgets a bag in the park -- "terror fear". Someone runs a red light -- "terror fears". Defacing of a lamp post "terror fears". It is as if they don't get paid or if they don't mention it.

Does anyone remember when beverage cans used to be so thick that it was considered an exercise of manliness to be able to crush a can--particularly a beer can--with one hand?

I had always wondered what the key innovation was that allowed aluminum cans to be made so thin. Based on a TV episode of "How It's Made", I think the key idea was to develop machinery that could delicately stretch and extrude aluminum without tearing it.[1][2][3]

Nginx is high on mine and my users' wish lists. I'm still trying to figure out if it's even possible to integrate with VirtualHostX (which is Apache focused) given the UI differences Nginx support would dictate or if it would be best to break Nginx support out into a new, standalone product. Some users might see a separate product as a money-grab, but I'm really at a loss as to how I'd combine Apache + Nginx support into a single product.
The Viola-Jones technique is still fairly competitive for face detection performance, IF you train it with a lot of data (and of course good data, which means with all the types of variations you expect to see). However, the pre-trained classifier provided with OpenCV is terrible (unless they've updated it recently).

Fortunately, OpenCV provides functions to train your own classifier using your own data, so if you can get good data, and are willing to wait for the week or two it'll take to process, you can get much better performance using the same technique.

Finding sufficient training data (labeled faces) is more tricky. For an automated approach, you could try bootstrapping it by simply running a more state-of-the-art detector (such as on Facebook, Google, etc.) and feedings the outputs into the training function (you'll need to do some work to actually get the outputs programmatically, perhaps through undocumented APIs).

Another approach is to use an existing face dataset. One possibility is the FDDB [1] although it's kind of small (5171 faces). Unfortunately, most other datasets I know of in the face community are either unrealistic images (e.g., only "mugshot"-style) or were detected using OpenCV (and thus won't help you get better).

The final approach is to label images yourself, which would require time and money (e.g., to do it on Amazon Mechanical Turk).

If you do decide to retrain classifiers, it's essential that you augment your data in various ways, such as by mirroring images (and labels) left/right, generating slightly rotated versions of faces, and at slightly different sizes. This augmentation can GREATLY improve the performance of your detector.

Introducing the Delite and Deliteful Projects
Back button hijacking like this is spam. Please stop selling this product. When someone hits the back button they want to leave. Forcing them to stay on the site after that action is wrong. Shameful. I know you won't care, because people who create things like this don't have an ethical compass, but sometimes I just can't help myself.
Why is this being downvoted? It's exactly right. The distance to beacons is extremely unpredictable. Just holding the phone or a beacon in your hand slightly differently is often enough to make the estimated distance change by 10m.

And yes, it's a huge barrier to usefulness.
This isn't just limited to finance. Language creates barriers in all fields, finance and science are the ones most familiar to me.

Programming as well -- someone recently looked alarmed when I told them to "kill" an app on their phone.
As I said already 'I seriously doubt that's the case.'
My one gripe is the font choice on your homepage. Makes it very annoying to read.
This is very true - although I think the "non-rational actor" argument needs some thinking through.

The Freakonomics model completely misses the fact that most agents don't often have enough houses to sell for the time spent on each one to be a constraint.

Given that, in many circumstances it really does make sense for the agent to spent an extra few hours working on your house if it will get you another 10K, because they get a small amount of money from that. It's true the marginal gains aren't high, but often they simply have nothing else to do!

Additionally, "working on your house" often means meeting more people who are interested in buying. Very often, some of those people will be looking for an agent to sell their house, so the agent sees that as an advertising opportunity.
As example, HackerOne allows you to link duplicate reports to the original, and all reporters are "thanked" when the issue is resolved. But I think in many cases reporters of duplicate issues do not get any follow up.
Self-fulfilling prophecy if anything.

It isn't working for me. I added some stuff to my card, tried to check out and got the message "Move your cursor to the cross or address bar as if you were about to abandon this cart", but nothing happens when I do as the message says.
It's also different in that the artifact signatures are there for you to check if you want to; it's just that most people don't bother, and even if you do, you probably can't tell which keys you should trust to begin with.

Ask HN: Freelancer inquiry etiquette?
I'm curious what people consider to be proper etiquette for communications between freelancer/consultant types and their potential clients. I recently became an independent consultant after 10+ years as a salaried developer and while I'm happy with my existing clients and work, I have noticed some quirks in communication when advertising my services.

Specifically, when I have posted in the Freelancer? Seeking freelancer? thread, I have had the following happen twice:

1. High-ranking person from company X contacts me with a brief problem description and asks whether I'm interested. In one case they also asked for my rates.

2. I respond in a timely, enthusiastic and well-crafted (if I may say so) fashion with the info they requested.

3. I never hear from them again.

I've played the online dating game (happily married now), so I have a thick skin for rejection and not getting a response. However, this is quite a bit different. First, these organizations contact me, seemingly with a need and with questions. They are asking me to take the time to respond. I fully understand that they probably contacted multiple candidates, but I feel it would be proper etiquette for them then to notify those who they don't select.

This is not like a job posting where the applicant initiates the conversation. The clients are starting and then abandoning the conversation.

In the dating game, my thoughts would be "They're flaky, you dodged a bullet", but these two requests came from a startup with a decent seed round and a large, established professional organization. So I'm wondering if this is an acceptable norm?

Would love to hear opinions from more experienced freelancers.
From the article and from what I understand around the site, they aren't losing money, they just aren't making profit from the revenues they have. I don't know what their books look like but it appears from what I have seen that they have pretty thin delta between income and outlays.

The bottom of a modern beverage can has a glowing blue ring that you can see only under UV light (aka black light). I've seen this on Coke, Sprite, and other soft drink cans.

The bottoms of the cans are coated with a varnish to make them slide easily on conveyor belts and in vending machines. It's the varnish that glows.

> This is not how it works. The government is not just one body and there are many parts of it that probably don't agree with what the NSA is doing.

This, I think, is a very important point. It is beyond naive to assume that a large body of structures that together are called "the US government" is a homogeneous entity that can be ascribed goals as if it were a single agent.
