What is an Azure Queue?

Azure Queues allow you to store a large number of lightweight messages leveraging Azure Storage. Typical use cases for queues include buffering a set of data or actions for processing. And since the Queues are part of Azure Storage they are super cheap. As of writing this, each queue message can be 64 KB in size and a queue can hold millions of messages (up to the capacity of the storage account).


Scott Hanselman has a post showing how an Azure Queue can be used along with Azure WebJobs to offload processing of images. This is a great example as it shows how a real application might accept images from a user in real-time, then use a queue as the hand-off for another service to actually process the images.

As another example, I have used Queues as a temporary staging ground for incoming IoT data from my connected SmartHome where a WebJob then took care of properly sorting the data and moving it to the destination Azure Table Storage location. This allowed me to take advantage of the massively scalable architecture of Azure Queues instead of having my logic running on a Web App where I would have had to take care of scalability.

I was just cleaning up my desktop and came across a snippet I had saved which removes a specified folder from a Git repository including removing it from the history of the repository. In general, if something was committed to a repository, you shouldn’t remove it from the history, but there are cases where it makes sense – perhaps a sensitive password or key was unintentionally commited.

The command is pretty simple, but be warned that it can have grave consequences if you remove the wrong thing:

git filter-branch --force --index-filter \
'git rm -r --cached --ignore-unmatch .idea' \
--prune-empty --tag-name-filter cat -- --all

git push origin master --force

In the example above, I removed the default .idea folder that is included with JetBrains IDEs like IntelliJ and Pycharm.

A summary of my findings with the Stick-N-Find stickers and their usability as an iBeacon / Bluetooth LE proximity device. I ordered a set of Estimote Beacons and Stick-N-Find stickers and have been playing with automation concepts within Android. In particular, I wanted to be able to have my Android device understand the proximity to a location and have a general understanding of indoor positioning.

Note: If you just want to know how to Configure your Stick-N-Find for use in Tasker, jump to Configure as iBeacon
