The Value of Personal Projects

Personal projects can be a great way to explore ideas, concepts, or frameworks before you use them on an actual work project. As somewhat of a staple of SEP’s Hackathons, I’d like to highlight some of my philosophies around personal projects and the value I’ve gotten out of them. I worked on all the projects […]

Analyze the Crap Out of Your Apple Health/HealthKit Data

As a recent iPhone + Apple Watch convert (see ya, Android and FitBit) my fitness tracking data lives in Apple Health. I want to make charts and graphs and see trends over time (you get the idea, I’m an engineer, I wantneed to engineer and analyze my fitness data). Problem is, there’s not a great way […]

Announcing PlanetEx: an open source blog aggregator written in Elixir

A long time ago, a few developers at SEP built a program to aggregate employee’s personal and internal SharePoint blogs. They called it Planet, after planet.rb, the Ruby gem they used to build it.

We’ve already gone through a lot of different programming language constructs, however we haven’t really talked about a very highly used feature. How do we think about methods using these diagrams. So there’s a lot we could talk about methods in general, but I want to avoid any specific digression into what object oriented and […]

Code Analysis: Exceptions

void Function() { try { RunOtherFunction(); } catch { Log.Error( "Problem" ); } } void RunOtherFunction() { if ( a_okay() ) { OtherFunction(); } else { throw new Exception( "Error" ); } } Exceptions are a thing that we tend to use for signaling error conditions such that the error will be dealt with in […]

Code Analysis: Global State

Global mutable state by itself can make a program harder to work with because instead of having a call tree that’s simply a tree structure, you end up with more of a graph structure. Any given point in the program that interacts with the global state can be effected by any other point in the […]

Code Analysis: Abstract Data Type

Abstract data types are a pretty well known concept in computer science and software engineering. The concept is pretty simple. If you have something that is complicated, then you can make it easier to deal with by only exposing an API that allows you to safely interact with the complicated component. Of course also known […]
