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,…

Continuous Delivery Overview

This blog post can be considered a follow up of my previous post regarding unit-testing. In this post, I share my experiences and ideas for continuous delivery (CD) systems.

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 synching". However, that got me thinking I should frame the…

mbloom

I've tried to stay out of this fray, but having received a number of inquiries, and having seen some friends affected by the collateral damage, I'm going to briefly comment on the situation.

I want mbloom to succeed. They have substantial capital to deploy in Hawaii, and I want that capital to empower local entreprenuers.

I believe the people at HSDC are true believers and want to do right by our community. They may have made mistakes, but I've spent time with them, and I've…

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…

Endless Possibilities in User Interfacing with Myo

As an engineer, you often find solutions to problems, not the other way around. However, once in a blue moon, a solution comes along that appears so interesting and full of potential that you feel compelled to dream up applications for it. Such is the case with Thalmic Lab's Myo armband. The inventors…

E-Commerce on Rails: Working with Spree

At work, I was recently tasked with building a web site wrapper around a Heroku software-as-a-service that we had built earlier last year (Bomberman).  While the core functionality of this new application is identical to the Heroku service, we were required to implement our own subscription service to replicate the purchasing and billing functionality provided by Heroku and throughout the…

Windows App Studio Review

Create apps for Windows 8 and Windows Phone 8.1 without coding.

The biggest issue facing Windows and Windows Phone is the relative scarcity of apps compared to Android and iOS.  Microsoft faces an uphill battle in attempting to sway companies and mobile developers into building apps for Windows Phone.  

One of the offerings created to help close this gap is called App Studio.  App Studio was first released last…
