Adventures in Scaling, Part 2: PostgreSQL

Several months ago, I wrote a post about REE Garbage Collection Tuning with the intent of kicking off a series dedicated to different approaches and methods applied at Miso in order to scale our service. This time around I wanted to focus on how to setup PostgreSQL on a dedicated server instance.

Persist your data in YAML files instead of SQL database. Wait what?

Why YAML Record? At Miso, we occasionally ran into situations where we wanted to persist simple data to a text (or yaml) file. Examples include landing page email forms, contact forms, feedback forms, about us “team” pages, etc. In these situations, we wanted a way to persist data to YAML and easily view the results in a text file but also manage the data through forms and controllers as any other data. To achieve this we have created a YAML-backed persistence engine called YAML Record that allows access to YAML based data using a familiar ActiveRecord API. If you have a small amount of data to persist which changes infrequently but that you do need…

Hybrid (Native + Web) Mobile App Development • Part 2: Maintaining EJS templates, and Bridging Interactions

Welcome to part 2 of this multi-part series of blog posts where we venture into the world of hybrid frameworks. This is where we get into the juicy stuff, if you are new to this, I suggest reading part 1 to understand the motivation behind this approach. Big Picture Stuff In a nutshell, what we’re trying to do here is mash a JSON response from a RESTful API call with a ejs (similar to rail’s erb) template to form the html to be rendered by a UIWebview. Simple, until you start asking questions such as how to an element to transition to a different state? How do you AJAX style interactions?…

Miso Hackathon I

Miso (and I) had our first Hackathon last week, and both of us survived! Our goal: conceive of an idea and build it within 3 days. We built Listify – an iPhone app that let’s you create, browse, and upvote lists of TV show and movies. Also with accompanying web landing pages. A Little Bit of Context At Miso, we’ve been working on making fun things for people watching TV, starting with check-ins, but experimenting with synchronized trivia, exclusive content, live Q & A. However, over the last three months, we’ve been focusing on ideas that connect friends around what they watch. Why a Hackathon? Entrepreneurs seem to be drinking…
