Intro Hi Folks. This is a follow up on my previous post about Google Sign-In. In this post we will discover what to do with the information retrieved in the first encounter, which you can find here: Google Sign-In Part 1. Forewords The Project Everything I did in the first post, and that I’m going to do in this example, can be found in this project: Google-OAuth-Go-Sample. Just to recap, we left off previously on the point where we successfully obtained information about the user, with a secure token and a session initiated with them. Google nicely enough provided us with some details which we can use. This information was in JSON format and looked something like this: ...
Update: This post ignored the fact that this works for utf-8 characters only. Characters which are stored on more than 1 byte will cause trouble. Look at this Effective Go Example. for pos, char := range "日本\x80語" { // \x80 is an illegal UTF-8 encoding fmt.Printf("character %#U starts at byte position %d\n", char, pos) } Prints: character U+65E5 '日' starts at byte position 0 character U+672C '本' starts at byte position 3 character U+FFFD '�' starts at byte position 6 character U+8A9E '語' starts at byte position 7 Keep this in mind when working with strings. ...
Quick reminder. If you have a never changing regex in Go, do NOT put it into a frequently called function. ALWAYS put it into a global variable. I’ll show you why. Benchmark for code with a variable in a frequently called function: BenchmarkNumber-8 30000 41633 ns/op BenchmarkAreaCode-8 50000 27736 ns/op BenchmarkFormat-8 50000 29263 ns/op PASS ok _/phone-number 5.110s Benchmark for code with the same variable outside in a global scope: BenchmarkNumber-8 300000 5618 ns/op BenchmarkAreaCode-8 500000 3884 ns/op BenchmarkFormat-8 300000 4696 ns/op PASS ok _/phone-number 5.197s Notice the magnitude change in ns/op! That’s something to keep an eye out for. ...
Hi folks. Today, I would like to write up a step - by - step guide with a sample web app on how to do Google Sign-In and authorization. ...
Hi Folks. So Wercker was not working. After a minor modification it seems to be okay now.

Basics Hello folks. This will be a quick post about how to do CORS with jQuery, Gin in Go with a very simple ajax GET and Json. I’m choosing JSON here because basically I don’t really like JSONP. And actually, it’s not very complicated to do CORS, it’s just hidden enough so that it doesn’t become transparent. First, what is CORS? It’s Cross-Platform Resource Sharing. It has been invented so that without your explicit authorization in the header of a request, Javascript can’t reach outside of your domain and be potentially harmful to your visitors. ...
Hello folks. I wanted to share with you my tale of working through the problems with Advent Of Code. It is a nice tale and there are a few things I learned from it, especially in Go, since I used that solve all of the problems. So, let’s get started. Solving the problems The most important lesson I learned while doing these exercises was, how to solve these problems. A couple of them were simple enough to not have to over think it, but most of them got very tricky. I could have gone with a brute force attempt, but as we see later, that wasn’t always a very good solution. And people who used that, actually just got lucky finding their solutions. ...
