Thread Synchronization using Event Object in Python - Interactive Brokers Part 4

This post uses the Interactive Brokers Python TWS API to explain Thread Synchronization using Event Object.

In many applications, sometimes, we need to pause the running of the program until some external condition occurs. You may need to wait until another thread finishes, or another callback is processed. In these situations and and many other similar situations you will need to figure out a way to make your script wait. Three common ways to achieve this are mentioned: 

1. This is sometimes achieved by using a "trial and error approach using the time.sleep() function in Python". While this may work, it is always a problematic issue in determining the amount of time we need to wait. And using the time.sleep() in such cases is not the right way of achieving the result. 
2. Another approach is to use flags to arrive at a better approximation in using the time.sleep() function.
3. Use the Event Object to achieve thread synchronization

Making blogger a little less painful

Table of Contents

• Formatting Source Code in Blogger
• Creating Table of Contents in Blogger

Recently google made an update to blogger for formatting code and inserting anchors in the Compose View itself(instead of HTML view). Yeah, it was just about the time when they came out with this fine separation between "blogger" and "legacy blogger".

The new changes they had incorporated was very good, focused as it was on simplicity . I actually used it to create one blog post which required the use of Table of Contents right from the "Compose View". I also used it to insert my Python code right from the "Compose View". Imagine the savings in time for somebody who makes a blog post daily ?

Suddenly a few days later all of it vanished as mysteriously as they appeared. Another Google+ ??? (oh yeah, that much touted alternative to Facebook)

Google seems to have done a veto on their recent updates to blogger. But yet I prefer google over some other blogging options like Medium becos in the near future google corporation don't need to worry about monetizing blogger , unlike the corporation run by Evan William's. ( He is the same guy who started blogger too , which was latter purchased by Google ).

So I began to think - How can I make blogging more easy on blogger instead of switching to another platform. Maybe google might bring those feature back, or maybe they wont. We don't know. So lets see what we can do for now.

I would like to cover the following issues which are of concern to me:

Formatting Source Code:

I have already dealt with formatting code in one of my previous posts. Check out one of my earlier post - Syntax Highlighter for Source Code on Blogs . This deals with code-prettify and unfortunately for us this is archived and is no longer maintained. So sooner than latter, we will have to look at alternatives.

The one I found most helpful was the use of gist. I have been using GitHub for a couple of years now and so it was the logical to continue with it.
