Find out how to nicely implement infinite scroll feature using AngularJS and Rails, by re-using regular Rails pagination conventions and the regular Rails CRUD/REST interface.
I put together my top pics of Schneems' series on Ruby on Rails introductory course centered on Rails use in conjunction with databases.
Heads up readers: I migrated my database from Heroku to localhost sqlite3. Then ran the SQL dump through a python script that was supposed to alter it enough that MySQL would understand it, but certain items weren't market as "published". I had to re-enable them, thus, all the blog posts that have been updated by me, are now showing at the top, as recently published, when they were not.
I've been inspired by the 'growl' like notification system and decided to build my own for my web applications. I've been using this code and style for notification systems in a couple of my projects and it has been well received. I will show you here how to add it to your own applications.
It's been busy over here. I've been working hard at this new web application which will launch under the domain: launchpage.me and will be part of a network of launchpage.me, launchpage.us, and launchpage.vc. I'm featuring here a few screenshots of the application up to this point and a little video of a UI feature I finished just now. Keep it steady.
Many developers [in an interview situation] get asked the question 'How would you move mount Fuji?' or one similar in concept. Here I will show you how, the idea is not mine, but it comes from, perhaps, just as much of an unlikely place :)

This is a great podcast/web episode of Mixergy with a very detailed interview with the found of Balsamiq (Peldi Guilizzoni), the UI sketching application.
This is a short video recording, of a much more detailed text tutorial of how to get started developing apps with WebKit, Python and GTK.
You can't scale while selecting all the data in you database on an ever increasing table size.
When you see queries that get all data from the database it's time take a break and really think about why you are doing that. Do you really need all that information? Or are you then going to filter it and extract only a subset of the data that you are getting?
At this point you could probably assume there is a better way of doing that, right in the query. It may not always be the case but it's highly likely that there is a better way to formulate your queries to get you the data you need faster.
In an introductory essay on Model Thinking, a free online course offered through Coursera, I came across this quote...
