What is benchmarking? Benchmarking is the process of measuring performance for a piece of technology against other pieces of technology. Typically, processors are benchmarked by running programs and software that heavily taxes the system. This allows the processor to truly shine (or, possibly, the opposite). For the purposes of this post, the i5 and i7 processors’ […]
The Relational Model & SQL The relational model was proposed in a paper published in 1970 by Edgar Codd, a computer scientist working at IBM. In previous years, some storage systems had already emerged, but the relational model was first proposed with a strong theoretical basis.
As part of my exploration of a minimum set of devops tools, I’ve been learning how to stack containers full of Rails apps onto the Docker. There are plenty of examples of how to get started with Rails and Postgres on Docker, even one from the whale’s mouth, as it were. Working from this example, […]
In the past we would often treat a server as a machine which has a variety of roles. A single server may be responsible for serving web content, email, processing background jobs, and even hosting a database system. Your application is really only one of the many things that runs on that machine.
A common way to describe requirements on Agile projects is through the use of user story mapping, and, as a result, user stories. This post will not cover this process, but rather the process of taking an existing set of user stories and leveraging them within our development workflow to ensure that an application is […]
I work from all over the place: Home, on public transit, the office, coffee shops, etc. A big challenge to developing android apps in an environment where my laptop and phone are on different networks (wifi vs. LTE, or laptop tethered through phone) is the inability for my phone to see the API server that […]
To get a better handle on Erlang’s behavior, I decided to install a popular set of tools for debugging and performance profiling: EPER. I think it stands for “Erlang PERformance tools”, but it could also mean “Everything Proves Erlang Rules” or “Egrets Prefer to Eat Robots” or really anything for that matter. One thing is […]
Many people know about services that allow you to ping your website to be sure it’s always online. The idea behind those is that they check every 5/10 mins sending a GET request to the given website and if they get an answer 200 they send you an email.
For the past year, I’ve been working mainly with AngularJS and before that Ruby on Rails. I’ve never heard of Meteor until a few weeks ago. I am intrigued by the idea of tightly connecting the client and server together in a synergistic manner that allows for fast responsiveness, which is what Meteor is all […]
Over the weekend I made performance optimizations to an internal web app that we use for time tracking and invoicing. The app runs on tomcat and is built using grails 2.4.2. Grails 2.4 included some major changes including asset pipelining. This is the first time I’ve tuned a grails app, and I had to do […]
