Using Heroku For Facebook Application Development - Common Errors

You might come across several issues while deploying facebook applications from heroku. This article describes most of the pitfalls you can avoid if you are are not very familiar with the environment. Mostly, I'd refer you to already existing tutorials that are hard to find on googling. These have been compiled together after several confusing research on the topic for long hours. Hope this might save someone's time if you are just starting up. This article is a supplement to the guide from Heroku
You could follow the guide as it is initially and then come back to this article if it doesn't succeed at the first few attempts.

Solution: Stackoverflow


Error 4
Command : git push heroku
fatal: 'heroku' does not appear to be a git repository
fatal: The remote end hung up unexpectedly
Solution: This happens simply because you are not inside the application folder. Browse to the application folder through the terminal and then run git push heroku again.



Error 5
Command : git push heroku

Response : Everything up-to-date

Although you've made changes to the files . When you deploy it those changes won't be reflected in your app running on the server. This is because we haven't commited the changes made to the application files.

Solution :
Remember that you have to commit the changes locally before you can push them.
If you do a git status, it should be clean.
If it's not (my prediction):

git add [path to your app folder]
git commit -am "Your commit message"
git push heroku master

Finally I'm done !

Building Autonomous Drone with Raspberry Pi and APM 2.8

I am a total newbie to hardware and was pushing my limits to see how far I can reach on with hardware projects (which sparked my interest lately). I have set out on a very ambitions mission  to control a drone from raspberry pi .I began the research for this around 2 months ago and had brought a raspberry pi, drone body kit and apm flight controller. The key difference of this project from common drone projects is that I'm trying to avoid the use of and RC and instead use the raspberry pi to control it.  Hardware Ins tallation Setup: I am using APM 2.8 and Mission Planner. I am using RPi 3 to control the APM 2.8 via Telem port of APM I am planning to power the apm via the battery to ESC (Electronic Speed Controllers) Now, documenting my steps below: Day 1 Watch Tutorial To get started with APM flight controller, I watched this video tutorial [1] which gives a gentle introduction about APM board.  Setup APM board and Calibrate Sensors I downloaded the APM Missi

Adafruit GFX - How to change line spacing in text?

  You may want to update the line spacing to be a little lower than default due to small screen size on IoT devices. I faced this challenge while working on a Watchy hobby project. You may have used a font generator or just using the default fonts and got a *.h file that has the details of the font. In that case just change the last integer value in the PROGMEM variable.
