RavenPlus Updates - 28th July 2015

Here are some updates on what's happening on my work with RavenPlus and OAuth2 since my last update about 4 weeks ago.

What's Working

I have completed the following functions in RavenPlus:

  1. Insert new post
  2. Update an existing post
  3. Delete an existing post
  4. Downloading recent posts (including Blogger labels)

The time taken for item (4) is a little longer because I had to take a detour to learn about Python's 'list', 'tuple' and 'dictionary'. Otherwise I could not proceed. I never had to in my previous fixes as there wasn't a need to.

When Keystrokes Triggered Nothing In Raven/RavenPlus

I was suppose to publish this post on 28th May 2015. Little did I know then that Google had planned to shutdown the ClientLogin authentication protocol on that faithful day. Obviously, my attempts to publish this blog post failed. If only they had published a notification on my Blogger dashboard (something that I login to everyday) rather then at their developer blogs and forums (something that I did not access until recently).

But irrespective, I still maintain that this is still the most difficult bug fix in Zoundry Raven/RavenPlus for me, despite my work on OAuth2 over the last couple of weeks.

The blog post follows below.

This must have been the most difficult bug fix for Zoundry Raven/RavenPlus so far. With variables to track and multiple levels of inheritance for certain Python Classes, pretty soon I got confused while tracing through the code. I have to virtually see the code in my sleep before I finally figured out the root cause of this problem: variables not being reset correctly after clicking the "Save" button within the editor. A very common programming mistake, if I may add.

I can only think of 2 states that the Raven/RavenPlus editor could be in at any one time - "Content NOT Modified" or "Content Modified". In the "Content NOT Modified" state, the "Save" button is disabled. Make any changes, by keying something on the keyboard for example, will change the editor from the "Content NOT Modified" to the "Content Modified" state. This should trigger an event to enable the "Save" button. Click on the "Save" button and the state will change back to "Content NOT Modified" from "Content Modified" - and disabling the "Save" button at the same time.

However, I have encountered a number of times when keying in something on the keyboard triggered nothing while editing. The "Save" button remains disabled no matter how many times I banged on the keyboard.

My Contribution To The 2015 MY Garden Birdwatch Survey

The table below is my contribution to this year's MY Garden Birdwatch Survey. I did my counting on 20th June 2015, between 4:00 PM and 4:30 PM from my bedroom windows upstairs. This is my fourth year of participation. Yeah! Me a citizen scientist.

A Jungle Myna

On That Day

Loud chattering at my front gate led me to catch sight of 2 Jungle Mynas. They are not common visitors to my home. So I guess a little bird must have told them about this year's birdwatch survey that I am conducting and they did not want to be left out.
