Free Developer Tools on Windows

It used to be that to develop with Microsoft technologies developers would have to pay up for development tools if they wanted the best experience.  These days with all the options developers have, getting someone to pay for tools can be difficult.

Recently I wiped of one of my development machines and realized this is no longer the case while installing various tools.  

It's well known that Microsoft has been moving towards open sourcing many of their projects like…

Our Immigration System Sucks – Is There a Tech Fix?

Sooner or later, everyone who is in the tech field for the long run bumps up against the U.S. immigration system. The tech talent pool is global, our engineering schools have plenty of international grads looking to be placed into U.S. jobs, and smart international investors are looking for U.S. tech entrepreneurs to back. And the unanimous reaction to the immigration encounter is “the U.S. immigration system really sucks!”

Continuous Delivery with WordPress

As a continuation of my blog posts regarding continuous delivery, I shall explore the continuous delivery options for WordPress websites since I was recently been involved in such a project.

One changing component of a WordPress website is its templates, which are written in PHP. This PHP source can be version controlled quite easily and integrated with a continuous delivery system.

However, another changing component of a WordPress website is its plugins and their…

We’re celebrating our having picked up two more engagements in June, for the States of Georgia and Oklahoma, with a tip of the hat to Andrew Hoppin ( who, several years ago, got me focused on a business model based on long distance, distributed project teams. Justin, of course, continues to do the heavy lifting.

Lately I’ve been reviewing issues of long distance worker health and safety, and of information security with respect to access to corporate information from the…

JavaScript Game Engines

Recently I’ve been interested in games created using JavaScript.  JavaScript is everywhere and works with a lot of devices and platforms including mobile devices that run on iOS, Android, Windows and FirefoxOS. On the web seems that games using HTML and JavaScript have started to replace those using older technologies like Flash.  Here is a list of JavaScript libraries that I have seen recommended for creating games. To compile this list I looked at libraries that are free,…

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…

Google API Authorization Using Oauth2 in Ruby on Rails

Say you are writing a web app that will help its users optimize their companies' online marketing.  In that case your web app would need to be able to access its users google analytics web site data.  The way you allow your site users to authorize your web app to to access their google analytics data, is with Oauth2. Oauth2 is a security protocol for third party application authorization.  When a user visits your web app, you present them with a link that will take them to a google page…

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.

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…

Nearly 2 years ago I blogged about my experiences using Windows Phone for 6 months. I’m back to update my impression of Windows Phone as a whole and also blog about Windows 10 for phones.  Windows Phone has gone through several updates and in early February 2015 Microsoft released the first Tech Preview for Windows 10 on…
