Been traveling more recently, and I've seen those ads in major cities like NYC or San Francisco, but not Miami.

> Simpson's paradox is when more button presses lead to more purchases. But then you look at desktop vs mobile and you find out that for both desktop and mobile more clicks doesn't mean more purchases (or worse, more clicks means fewer purchases).

How could more button presses lead to increased conversion rates while hiding this data when comparing desktop and mobile? Wouldn’t you see at least one device type demonstrating higher CVR to reflect aggregate CVR increase?

> But what else is there to measure other than checkout button click count(and follow up purchases) to measure the effect of button color change?

Purchases occur on the checkout page itself. Its design, payment input, and upsells can all impact results, potentially counteracting the button color's effects. You need a clearer hypothesis to address these.

I feared this, but also figured if someone is spamming the channel, then it's time to talk to them about understanding how the product is meant to work and that spamming doesn't help anybody.

The problem I see with the product so far is that all the images appear to be renders, and not actual product shots.

Also the demo video shows shots from what appears to be a drone; is it the actually Nixie, or is it another drone used to exemplify what the Nixie would be able to do?

I want this to be real.

Would be cool to have an API. Could be useful for mass address book creation.

I'm having some trouble understanding what your product does exactly. The blue check isn't an official verification is it? It's just one chosen by bluecheck, correct?

It's also written down in the FAQ section of the page. But I was thinking the same thing.

Is this the same group of people he brought up on the recent episode of The Talk Show? The group that wanted to essentially take away the original credits (or something to that effect) from him?

I'll talk to something that Pillow did for me that I couldn't easily find in other sleep tracking apps: audio recording. For the past couple of months in my new place, I couldn't figure out why that no matter how much sleep I got, I still woke up absolutely drained and tired. Other sleep tracking apps showed nothing out of the ordinary in my sleeping patterns and they even matched previous sleep cycles.

After the first night of using Pillow, I immediately found the problem. I learned that throughout almost the entire night I would go into these throat-scratching fits. The reason the other apps didn't show anything is because my movement didn't change, I would just lay there and scratch my throat. On a recording it sounds like a frog croaking. Except this would go on for 15-20 minute intervals nearly 8 times throughout the night. This was a clear sign of my allergies; whenever I'm awake and up and I knowingly make that sound, it's because something is irritating my allergies to such a degree that "throat-scratching" helps soothe it. Now I take a generic Zyrtec before bed, and I sleep like a baby again.

Now this wasn't a very scientific test (I didn't use Pillow or attempted audio-recording before I moved into the new place), but it showed me how easily this information could help me and my doctors. Now connecting this app, with other health apps I use on a whim (weight-tracking, food-tracking, etc). I could make correlations (but not causations) into what could be making me "sick".

To the poster who said "your body knows how to take care of itself", in relation to sleep, that really isn't true for me. From someone who suffers from multiple things that directly affect my sleep, I can tell you my body does not know how to take care of itself. Apps integerating with each other will help find more data relevant to one other than most of us realize. Trying new things, and see how we are affected by them, with data to back it up, will be greatly helpful.

Wow. I hate how so many Windows applications are considerably uglier compared to Mac counterparts. The Windows apps don't seem to push forward Windows design but rather get stuck in the Windows XP design days. This is beautifully designed and clear.

The graph visualization is prime, and I love that the peaks are "rounded" out instead of sharp declines (sharp declines would make it look more like a live stock ticker).

Extremely well done, and exactly something I have been looking for. I will keep an eye out for the Mac version.

Reminds me of Wishclouds (http://wishclouds.com/)

I think the reasoning they are shooting for 24 is because their application seems to be based around contextual conversation. Having a retention period of zero pretty much eliminates context.

Apps like Snapchat, deleting the message as soon as it's viewed, wouldn't work when you want to apply a ton of context in the conversation. Too often I'm having a "conversation" on Snapchat but it's more like small snippets of text and a lot of me questioning what the other person said a few hours ago.

This is where I was really confused. Why didn't the author take this approach? It's definitely the route I would try.

So the author seems angry to say the least. But he brings up a great point. What would the best alternative be in this situation? Apple? Firefox OS? Blackberry?

I love Couple, I really do. But they have seemed to slow down development and taken focus into different areas and not exactly improving the application.

Although this is cool, I really wish some features were brought to the app (data exporting, bringing search back, etc.)

Following in line with this thought, I've actually plugged in my iPhone (non-jailbroken), downloaded the sqlite database onto my computer, and was able to see all the messages and URLs of photos sent. Even photos marked as "secret" (the apps Snapchat-like feature of deleting and hiding photos).

Reading the article, and seeing where the author is coming from, and I honestly don't see it in the way that he describes.

An engineer (one in the classic sense), and a software engineer (someone who engineers code and bits to create software) can both be explained as "I find solutions to otherwise complicated issues others cannot while encompassing outside and unforeseen circumstances". Now, that phrase there can be applied to a thousand other careers and jobs.

But I think we use the term software engineer because we haven't quite come up with a "perfect" term to describe what is being done when code is being written.

Writing software is not easy for all people. Just like writing a paper is not. Understanding logic, flows, and cross-compatibility takes experience, time and understanding.

That said, I don't think the term software engineer is completely incorrect, but I also don't believe it is the best one to use either. I see it as we will either find a better term for what we mean when we say 'software engineer', or just end up using that generic term because it is understandable enough to describe an umbrella definition.

I'm not sure why this on Hacker News. This whole website has a "scammy" feel to it.

Yup yup. I believe he/she was referring to that.

Open source iOS apps are extremely helpful to anyone learning iOS development. There are intricacies to learn, and not everywhere teaches it all. Looking at someone else's completed iOS source code you can learn and understand UI/UX design patterns, the MVC process of creating iOS apps, and so much more.

I recently took a course in college for iOS development, and because of open-source code I was able to ace the class and get picked-up for potential funding on the class project.

Yes you need to pay Apple the $99 to get it on your own device, and no you don't need to jailbreak (unless you want to circumvent the $99). Plus there are other ways to get the app on your device without paying or jailbreaking (creating your certificates, etc).

Agreed. I'm going to play around and see what I can learn from it, but a small tutorial would help me get jump started as well. Whether it be the coding aspect, or just ideas on how to implement different animations.

For testing purposes, wouldn't using Dropbox suffice as well? It gives a quick way to update the JSON and see changes occur near live in app?

I wonder if using iOS 7's mesh networking feature, if this would be more easily feasible (discoverability of other devices).

Doesn't Vimeo do pretty damn well with this? Or are you looking more for snippets of animation/shots, instead of Vimeo's YouTube length videos?

This was the only possible end.
