Today I Learned — The App

People who know me know that I’ve been pretty busy lately. People who really know me know that I’m actually slammed. Yet, I’m taking a personal challenge to complete a small application in the month of March. As it turns out, I have an idea for a small bite-sized application that I can build in a month. It’s also a great chance to challenge myself to learn new frameworks and libraries.

The Problem

I’ve…

Remembering 3/11 and Twitter

I was sitting at my desk on the 6th floor with a fresh cup of coffee that I bought from Tully's downstairs. They're a bit pricey, but they smelled and tasted so good I could never resist. I usually got a hot cup of the daily special and did so that day.

Took a few sips and started a discussion with a colleague about the project that we were on.

The desk I was assigned to was in the corner with a window overlooking a major street and I could see down it all the way to Shimbashi…

Ruby on SOAP

The slightly misnamed SOAP (Simple Object Access Protocol) protocol is in a sense a type-strong version of the much better know JSON interchange format.  The Ruby community clearly doesn't have as much affection for SOAP as the Java and .Net communities, but that makes sense as Ruby is a dynamic language with duck typing, which meshes better in philosophy with the lightweight JSON format, rather than the much more expressive and heavyweight SOAP format.

If given the choice between…

Programming for Kids

One thing I noticed in 2014 was an overall push to “learn to code”. Today computers are everywhere and we are only getting more reliant on them every day. It makes sense that more people and kids in particular are being exposed to programming. Here are some resources that I have found very easy to set up if you want to teach your kids about programming. Since I mainly use Windows this will be mainly a Windows centric post.  Also because this is a list of resources for kids I am…

10 of My Debugging Tricks

Being able to solve problems and fix bugs is probably high on the list of things that make a programmer a good programmer.   These days programming is assisted with many tools and techniques.  Stepping through code using advanced IDEs and debuggers find many issues before they become issues.  Intellisense, code completion and syntax highlighting also reduce bugs before they can become bugs.  Exception handling and error logging help a lot when issues occur in programs.  Testing…

Nodeschool in Honolulu

At the time of this writing, we have had two Nodeschool events here in sunny Honolulu, so tl;dr it’s been pretty successful. Admittedly, I had concerns going in to the first event. Sure, Nodeschool has been successful worldwide with new chapters opening every day, but that doesn’t mean it’d be a guaranteed success. Being the organizer for Ohana.js (our local Javascript…

The Neglected Requirements Process

In my experience with software development thus far, I find that requirements analysis is often overlooked or completely ignored. I believe that by not spending some time understanding the need for the software that's about to built, the developers may really be building an inferior product, which in the end is costly for the stakeholders of the project.

From my experience, there is often the misconception that the requirements process, in which requirements are discovered, is a slow…

Testing in iOS7 and Kiwi

For whatever reason, testing did not seem to be a focal part of Apple's development tools until Xcode 5. Prior to then, tests were typically implemented using OCUnit, but it was difficult to integrate with the Cocoa framework. That changed in Xcode 5, where OCUnit was swapped out for XCTest…

Importing large data sets in Rails and Postgres

In one of my recent projects, I needed to import a lot of data from csv files into a database as persisted domain objects in a web application.  This file import functionality wasn't just for application bootstrapping or a one-time legacy data migration, but for a recurring task that allowed the web app to receive updates from a third party vendor.

The number of records in each file could reach into the millions, so I knew from the outset that the plain-vanilla method of creating…

writing a json api service in Rails

In the past few years, I've written a few json API's in rails.  There are a few trends driving the popularity of API's, one being Service Oriented Architecture, and another being client side rendering.  

Service Oriented Architecture can apply to all services, not just browser accessible ones.  It consists of making services available via a standard like SOAP or JSON, to increase re-usability and modularity, SOAP and JSON being the two most popular SOA protocols.  SOAP is XML-based,…

Real Time Bidding in Online Advertising

The motivation behind this blog was a question on how different online advertising partners identify you and coordinate their ad efforts in real time bidding ("RTB") for a slice of your attention when they show you an ad. This is meant to explain a technique called "UUID…

Battling Click-Bait and Sustaining the "Hill of Wow"

Revulsion of click-bait content has recently boiled over again, accompanied by some fascinating analysis about how higher quality, more meaningful content is so much better at engaging readers for longer amounts of time and the tantalizing thought that ““you’d probably do better sitting on the right hand hill”... …

Observing Tech in Japan

Recently I visited Japan.  The last time I visited was in 2010.  Japan has always been known for it’s electronics and technology so I was looking forward to seeing how it’s changed in four years and how it differs from the U.S.  These are just my personal observations so they may not be indicative of actual trends or market share figures.

Unit-Testing T-SQL Projects

Recently, I've been tasked with maintaining software that is driven by T-SQL. Unfortunately, these applications did not have sufficient documentation describing what the software does and what its expected behaviors are. Thus, I was thinking of a low-cost and simple way of introducing unit-testing so that I can have a better understanding of what's going on in the software and to provide a means of stating my assumptions on what the expected behaviors are.

In this post, I describe in…
