Spaceballs

I like to hone my problem-solving skills by going over some programming contest questions and I also like to use programming contest problems in interviews because it allows me to gauge whether the candidate is a just a coder or a problem solver. That's not to say that if you can't come up with a correct solution, you aren't a problem solver -- if I'm the interviewer, I'm more interested in how you approach the problem and whether you can break up and present the problem in an abstract…

Where to work

We work on long distance projects from home offices. We should have invested in solar years ago. Now Hawaii Electric is telling us we'll have no power as they replace telephone poles in our area. We're scrambling to find a place with access to the Internet from where we can participate in Skype and GoToMeeting scrums. Any ideas?

A Look at Windows 10 Technical Preview Build 10061

With the rumored end of July release date of Windows 10 here is a look at where Windows 10 is today.  The current build is the most refined one yet, but is still very buggy and hopefully…

Bootcamp'd: A Retrospective

“I never want to become a teacher.” — 20 year old me.

I stood at a crossroads as a junior in college. Organic Chemistry had destroyed any hope I had of going to medical school. I had declared Biology as my major, but I began to have second thoughts. I fell back on the thing I was good at, which was Mathematics. Still, I wasn’t sure what I would do with that degree.…

C# Architecture Preference

Having worked on many software projects written in C#, I've come to prefer certain conventions when creating the architecture of a C# project. In this highly opinionated blog post, I will share these personal preferences, which I hope may be of some value to the reader.

Single Solution, Multiple Projects

If possible, I prefer not to hunt down projects that ultimately make up the product. If a product is a collection of projects, then I think this should be bundled as a Visual…

Rails on Windows With Bitnami

When I first started learning Ruby on Rails back in 2007, one thing was made clear: don’t even try setting it up on a Windows machine. Since then, we had some open source projects like RailsInstaller that make it really easy to set up a development environment on your machine. Also, with the advent of virtual machines…

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…
