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.

How Packages Work in Go

Since I started writing code in Go it has been a mystery to me how best to organize my code and use the package keyword. The package keyword is similar to using a namespace in C#, however the convention is to tie the package name to the directory structure. Go has this web page that attempts to explain how to write Go Code. http://golang.org/doc/code.html When I started programming in Go this was one of the first documents I read.

Running Go Programs as a Background Process

I have been writing Windows services in C/C++ and then in C# since 1999. Now that I am writing server based software in Go for the Linux OS I am completely lost. What is even more frustrating, is that for the first time the OS I am developing on (Mac OSX) is not the operating system I will be deploying my code on. That will be for another blog post. I want to run my code as a background process (daemon) on my Mac.
