Mongodb dump and restore from mlab
  • install mongodb on local machine (mongodump & mongorestore) commands are required.
  • command dumping

mongodump -h xxx11.mlab.com:11 -u user -p password --authenticationDatabase release-db -d release-db -o /home/dumps

**Options** `-h`: mlab host:port, `-u`: db user, `-p`: db user password, `--authenticationDatabase` `-d`: mlab dbname, `-o`: path to store backupfiles

  • restore command, to restore locally

    mongorestore --db dname /home/dumps

Otherwise to restore in mlab, create a new db and replace the options

Demo: Coordinating async React with non-React views

Demo: Coordinating async React with non-React views

tl;dr I built a demo illustrating what it might look like to add async rendering to Facebook's commenting interface, while ensuring it appears on the screen simultaneous to the server-rendered story.

A key benefit of async rendering is that large updates don't block the main thread; instead, the work is spread out and performed during idle periods using cooperative scheduling.

But once you make something async, you introduce the possibility that things may appear on the screen at separate times. Especially when you're dealing with multiple UI frameworks, as is often the case at Facebook.

How do we solve this with React?

The way I like to work with 'ws' is to convert everything to an event if possible.

Launch Sublime Text 2 from the Mac OS X Terminal

Launch Sublime Text 2 from the Mac OS X Terminal

Sublime Text 2 ships with a CLI called subl (why not "sublime", go figure). This utility is hidden in the following folder (assuming you installed Sublime in /Applications like normal folk. If this following line opens Sublime Text for you, then bingo, you're ready.

open /Applications/Sublime\ Text\ 2.app/Contents/SharedSupport/bin/subl

You can find more (official) details about subl here: http://www.sublimetext.com/docs/2/osx_command_line.html

How to proxy web apps using nginx?

Virtual Hosts on nginx (CSC309)

When hosting our web applications, we often have one public IP address (i.e., an IP address visible to the outside world) using which we want to host multiple web apps. For example, one may wants to host three different web apps respectively for example1.com, example2.com, and example1.com/images on the same machine using a single IP address.

How can we do that? Well, the good news is Internet browsers
