tmux cheat sheet

(C-x means ctrl+x, M-x means alt+x)

Prefix key

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

remap prefix to Control + a

Go to Bitbucket and create a new repository (its better to have an empty repo)
    git clone [email protected]:abc/myforkedrepo.git
    cd myforkedrepo

Now add Github repo as a new remote in Bitbucket called "sync"
    git remote add sync [email protected]:def/originalrepo.git

Verify what are the remotes currently being setup for "myforkedrepo". This following command should show "fetch" and "push" for two remotes i.e. "origin" and "sync"
    git remote -v

Configure Git to use a proxy

In Brief

You may need to configure a proxy server if you're having trouble cloning or fetching from a remote repository or getting an error like unable to access '...' Couldn't resolve host '...'.

Consider something like:

s-leroux

var mongoose = require('mongoose');
var url = 'mongodb://localhost:27017/conFusion';
mongoose.connect(url);
var db = mongoose.connection;

var assert = require('assert');

var Dishes = require('../models/dishes');
var Promotions = require('../models/promotions');
var Leaders = require('../models/leadership');

        final CircleProgress p = new CircleProgress();
        p.setProgress(100);
        p.setClockwise(true);
        p.setStartAngle(CircleProgress.START_9_OCLOCK);
        hi.add(p);
        
        final ArcProgress p2 = new ArcProgress();
        p2.setProgress(70);

How I Created HTTP Prompt and Got 5000+ Stars on GitHub

Two months ago, I published an open source project, which went viral by gaining 1200+ stars in the first 24 hours. As of this writing, it has attracted 5000+ stars. The project is called HTTP Prompt:

https://github.com/eliangcs/http-prompt

Here I want to share its development story.

It all began with Vertica. Not long ago, I used Vertica every day for my work. Vertica is a powerful database, but the official client (vsql) is not powerful at all. The GUI alternative, DbVisualizer, is bad as well.
