Concurrency, Goroutines and GOMAXPROCS

Introduction When new people join the Go-Miami group they always write that they want to learn more about Go’s concurrency model. Concurrency seems to be the big buzz word around the language. It was for me when I first started hearing about Go. It was Rob Pike’s Go Concurrency Patterns video that finally convinced me I needed to learn this language. To understand how Go makes writing concurrent programs easier and less prone to errors, we first need to understand what a concurrent program is and the problems that result from such programs.


Be Selected To Attend GopherCon 2014

Gopher Academy announced a great program today. Today I’d like to announce the GopherCon Scholarship Program. It’s goal is to increase the visibility of women in the Go community through the most direct path I can imagine: sponsoring their attendance to GopherCon 2014. The program works by you purchasing one of these special tickets. There will be a selection/nomination process and those woman selected will be able to attend GopherCon thanks to you.

Go Package Management For 2014

Introduction In October 2013 I sent out a call to action to the Go community. I wanted to form a group of Gophers that would come together and help write a specification and build a working implementation of a package management tool. We are not there yet, but the group did accomplish a few things: We started a mailing list called Go package management [go-pm] where people could discuss ideas and get feedback on existing and new tools.

Macro View of Map Internals In Go

Introduction There are lots of posts that talk about the internals of slices, but when it comes to maps, we are left in the dark. I was wondering why and then I found the code for maps and it all made sense. https://golang.org/src/runtime/hashmap.go At least for me, this code is complicated. That being said, I think we can create a macro view of how maps are structured and grow. This should explain why they are unordered, efficient and fast.

Queue Your Way To Scalability

Introduction The first thing I did when I started programming in Go was begin porting my Windows utilities classes and service frameworks over to Linux. This is what I did when I moved from C++ to C#. Thank goodness, I soon learned about Iron.IO and the services they offered. Then it hit me, if I wanted true scalability, I needed to start building worker tasks that could be queued to run anywhere at any time.



Building A Weather App Using Go

At Ardan Studios we have spent the last 6 months, in our spare time and on weekends, building a consumer based mobile application called OutCast. The mobile application is tailored towards those who like spending time outdoors, whether that be fishing, hunting or any other type of activity. This first release of OutCast shows the conditions for the buoy stations and marine forecasts areas within the United States. All this information is updated every 10 minutes and there are map views with traditional grids and search.

Write Your Go Programs Using GEdit

This is a guest post from Tad Vizbaras from Etasoft in South Florida. There are a number of editors and IDEs for Go development. LiteIde, Vim, Emacs and GEdit just to name a few. Each developer has their own favorite editor for each language they work with. Some like full featured IDE environments while others prefer speed over features. My personal favorite editors for Go development at the moment are Vim and GEdit. GEdit comes as part of many Linux distros.
