New Codecademy Course Review Command Line

Codecademy launches new BETA course on Command Line.
Useful for beginner Ruby on Rails and Python coders.


Recently Codecademy.com more than stepped up its game to launch new blockbuster and real-world relevant courses like Rails Authentication, AngularJS and Command Line. The new command line course is short, 1-hour long, aims to introduce learn-to-code students to basic shell commands like ls, pwd, touch. As usual, the practice is completely interactive and self contained in the browser. Students equipped with desktops of all Operating Systems can easily play with code as long as there's internet connection.

While the Codecademy.com website is responsive, the exercises, however, are not responsive. It is the best to use a Chrome browser to complete exercises and avoid unnecessary browser-specific complications.

Investing in learning Command Line early is a wise choice (personally, one of the best choices I have ever made). Command line basics are extremely important in Ruby on Rails, Python and Django development, and Heroku Deployment. It's like JavaScript, there is no escape.

The early BETA course set is quite easy, at most, 1-2 lines of commands per exercise.

Developer Tools to Keep in Mind - A Learn to Code Guide for Beginners


Fitness Tracking with Pebble Time - Use Pebble Time with Jawbone UP


The new Pebble Time works with Jawbone UP fitness tracking using its build-in accelerator and manual sleep tracking app, no Jawbone UP device required. Jawbone UP is an official Pebble Time partner. The feature requires a bit of a setup but essentially is well supported and work seamlessly.

Up for Pebble watchface displays time with progress
proportionally to your daily goaln


Setup requirements


Caveats :

The UP for Pebble watch-face displays step progress along with digital time. The upward app has small dots that represents your daily goal (which you can set in the UP app). The dots will proportionally turn into little squares as you progress towards your daily goal.  See picture

Note the UP for Pebble "app" is actually a watch face (versus a  pebble app) that you would install on Pebble Time.  Search for "up for pebble" in the "watchface" tab.

Jawbone UP purple app works well with
Pebble Time no additional device required



Just like the Pebble Time requires a different iOS app from the old Pebble, Jawbone UP app requires you using the UP app with a purple icon if you have no UP device (versus the blue account). The Jawbone UP app "purple" is essentially a free and awesome fitness step tracking app for anyone with iOS!

Here's a longer video I found on Youtube that explains this in details. Caution the beginning is a bit loud
