  2. Run specs $ rspec demo.rb
func main() {
s := time.Now()
args := os.Args[1:]
if len(args) != 6 { // for format LogExtractor.exe -f "From Time" -t "To Time" -i "Log file directory location"
fmt.Println("Please give proper command line arguments")

Configure GitHub token with gnome-keyring
  1. git --version
git version 2.17.1
  1. sudo apt-get install libsecret-1-0 libsecret-1-dev
  2. cd /usr/share/doc/git/contrib/credential/libsecret
  3. sudo make
  4. git config --global credential.helper /usr/share/doc/git/contrib/credential/libsecret/git-credential-libsecret
  5. Next time Git asks for your GitHub username and password, just write your username and paste your token and they'll be stored in your keyring.

This is an example of a .gitlab-ci.yml that is required for Continuous Integration on GitLab projects.
# Reference: https://www.exclamationlabs.com/blog/continuous-deployment-to-npm-using-gitlab-ci/
# GitLab uses docker in the background, so we need to specify the
# image versions. This is useful because we're freely to use
# multiple node versions to work with it. They come from the docker
# repo.
# Uses NodeJS V 9.4.0
image: node:9.4.0
# And to cache them as well.

Allow Docker Container Access to Host's Postgres Database on linux (ubuntu)

You have to do 2 things in order to allow your container to access your host's postgresql database

  1. Make your postgresql listen to an external ip address
  2. Let this client ip (your docker container) access your postgresql database with a given user

Obs: By "Host" here I mean "the server where docker is running on".

Make your postgresql listen to an external ip address

Find your postgresql.conf (in case you don't know where it is)

$ sudo find / -type f -name postgresql.conf

require 'fiddle'
SIZEOF_HEAP_PAGE_HEADER_STRUCT = Fiddle::SIZEOF_VOIDP
SIZEOF_RVALUE = 40
HEAP_PAGE_ALIGN_LOG = 14
HEAP_PAGE_ALIGN = 1 << HEAP_PAGE_ALIGN_LOG # 2 ^ 14
HEAP_PAGE_ALIGN_MASK = ~(~0 << HEAP_PAGE_ALIGN_LOG) # Mask for getting page address
REQUIRED_SIZE_BY_MALLOC = Fiddle::SIZEOF_SIZE_T * 5 # padding needed by malloc
HEAP_PAGE_SIZE = HEAP_PAGE_ALIGN - REQUIRED_SIZE_BY_MALLOC # Actual page size

Combining snapshot testing and component library -- ReactiveConf 2017 talk proposal

This is a proposal for a lightning talk at Reactive Conf. Please 🌟 this gist to push the proposal!

Combining snapshot testing and component library

Do you test presentational logic of your components? No? Yes, but you feel like you are writing a lot of dummy tests? You even probably use snapshot tests for that, but don't feel like you make enought value from them..

If so, click 🌟 button on that Gist!

I'll talk how our team is using snapshot testing to iterate faster,
