Disclosure: I work at Heroku.

Yes, there are people who move from AWS to Heroku. The decision to choose Heroku over AWS can be multifaceted, but usually comes down to a couple things: development experience and operations experience. Heroku strives to make the process of developing and launching an app extremely simple yet incredibly powerful. Providing a toolchain that simplifies the configuration of production-ready app execution environments enables developers to focus on what they're awesome at - developing great apps. And not having to become an expert on provisioning, scaling, and maintaining individual pieces of infrastructure can eliminate or reduce the necessity for dedicated DevOps.

Is Heroku the right choice for every app? No. However, Heroku hosts everything from small exploratory apps to sites like Upworthy and Urban Dictionary, so is likely worth your consideration. If you're interested in talking a bit more offline you can reach me at theandym at heroku dot com.


I'll add my interest in adding a Spotify integration. I'd definitely pay $ for it.


Agreed. This type testing has been relegated to individual browser testing for too long. Hopefully tools like this will enable teams to address browser-side performance testing in the same way that tools like New Relic have enabled app-side performance evaluation.


I owned a pair as well until I left them in the seatback on a flight. I was given them as a gift and really enjoyed them - the quality and isolation provided by the noise cancelation was very good considering the price range.

I will say that it is somewhat inconvenient to have to enable the noise cancelation in order to use at all. There are some instances when I prefer to have some external awareness, and this didn't really accommodate that need.

Overall, I think these are a great option for someone looking for a pair without significant tradeoffs and with limited time to research. That said, there are definitely pairs with better quality out there. If you have the time I highly recommend reading reviews on Head-Fi prior to purchasing.


For Rails Rumble last year I created a Rails app for generating test data in various formats. It definitely isn't as polished as this (only had 48 hours), but allows for the user to specify their own format. After the competition I cleaned it up a bit more and converted the data generation functionality into a standalone Ruby gem. I'd appreciate any feedback...

Scrollbars are virtually non-existent on Macs these days. Plus this works well on touch-based devices too. Overall, I like the concept and find it useful as well.

Edit: I'm referring to the reading progress bar concept, not to the loading status referenced in the original post.


Fair enough, and good point on the touch-based devices, I can see how it would be useful for those. I don't use a Mac, so can't comment but same applies.


Scrollbars aren't but they still show on a scroll event (unless I'm mistaken - I'm only using 10.8).


Thanks, I appreciate the link.


Thanks for the input, that makes sense. I can't remember the last time I intentionally visited their site, but ran across this article and it seemed as if it had enough merit to share.


Here are my results running it in production mode (RAILS_ENV=production rails server >/dev/null 2>/dev/null):

ERB: 9.619 seconds

Haml: 10.893 seconds

Slim: 10.195 seconds

Very good points. Any specific variable types / sets that'd make it more useful for you (or devs in general)?
