Gustavo's IEEE-754 Brain Teaser

Back in June, Gustavo Niemeyer posted the following question on his Labix.org blog: Assume uf is an unsigned integer with 64 bits that holds the IEEE-754 representation for a binary floating point number of that size. How can you tell if uf represents an integer number? I can’t talk for you, but I write business applications. I just don’t have the background to quickly knock out an answer for a question like this.

An RSS Feed Searching Framework Using Go

This article was written for and published by Safari Books Online Back in May, I finally decided that it was time to move away from the Microsoft stack to Linux. The cost of developing, licensing, and purchasing cloud computing on the Microsoft stack is too expensive. My company was approved for BizSpark, which made development possible for a small company like mine, but what am I going to do three years from now?

An Open Source Debate

This article was written for and published by Safari Books Online If you read my article titled Analyze Data With MongoDB and Go, then you will understand the context of this debate with the idea of open source. That article talks about an application we are building, and it publishes some of the proprietary data we are gathering. It also shows techniques we are using to perform the data analysis. This has caused a passionate debate among the business partners in my company.

Understanding Pointers and Memory Allocation

In the documentation provided by the Go language team you will find great information on pointers and memory allocation. Here is a link to that documentation: http://golang.org/doc/faq#Pointers We need to start with the understanding that all variables contain a value. Based on the type that variable represents will determine how we can use it to manipulate the memory it contains. Read this post to learn more: Understanding Type In Go In Go we can create variables that contain the "value of" the value itself or an address to the value.

Analyze Data With MongoDB and Go

This article was written for and published by Safari Books Online My company is building a mobile application called Outcast. The idea behind Outcast is to give people who love the outdoors the ability to get ahead of the weather. By analyzing real time buoy, tide, lunar and solar data with user preferences and experiences, the application can deliver relevant information and forecasts. The user helps with the forecasting by providing an experience review after their outdoor activities have ended.



Object Oriented Programming in Go

Someone asked a question on the forum today on how to gain the benefits of inheritance without embedding. It is really important for everyone to think in terms of Go and not the languages they are leaving behind. I can’t tell you much code I removed from my early Go implementations because it wasn’t necessary. The language designers have years of experience and knowledge. Hindsight is helping to create a language that is fast, lean and really fun to code in.

Singleton Design Pattern in Go

Multi-threaded applications are very complicated, especially when your code is not organized and consistent with how resources are accessed, managed and maintained. If you want to minimize bugs you need philosophies and rules to live by. Here are some of mine: Resource allocation and de-allocation should be abstracted and managed within the same type. Resource thread safeness should be abstracted and managed within the same type. A public interface should be the only means to accessing shared resources.
