In practice-go we often use table driven testing to be able to test all function scenarios. For example the FindAnagrams() function returns us a list of anagrams found in the dictionary for given input. To be able to test this function properly we need to test multiple cases, like empty input, valid input, invalid input, etc. We could right different asserts to make it, but it’s much more easier to use table tests.

Authentication usually is very important part in any application. You can always implement your own authentication system, but it will require a lot of work, registration, forgot password form, etc. That’s why OAuth2 was created, to allow user to log in using one of the many accounts user already has.

A couple of months ago I moved from a Team Lead position to being an engineering manager at Wizeline Vietnam on a small sized team. I’ve found that this role change come with a mindset change. Some things that mattered before when I was an individual contributor (writing good code, applying best engineering practices) became less important. On the other hand, new things became more important, e.g. team health, team success and team career growth.

Telnet games were very popular some time ago, especially this Star Wars movie: telnet towel.blinkenlights.nl.
I wanted to create something in Go, and I wrote this Snake game over Telnet.
I am enjoying writing programs in a short time, like in a Hackathon way. Here in Vietnam we don’t have Hackathons often, so yesterday I decided to make one for myself with a time limit in 3 hours. The goal was to build/deploy something that will work and people can try it. I decided to go with Bot for Slack (or another messenger in the future).
Simplest possible solution for communication between services is to use JSON over HTTP. Though JSON has many obvious advantages - it’s human readable, well understood, and typically performs well - it also has its issues. In the case of internal services the structured formats, such as Google’s Protocol Buffers, are a better choice than JSON for encoding data.
