We all love slacking and we all love slack. See what I did there.. wink. Its the new bad boy of the corporate messaging market. It pretty much blows all of the other messaging solutions out of the water including skype and lync with its slack app add-on’s. In this post we will talk about one such add on that I wrote recently to setup an integration between Rally and Slack.

Personally I am more of an Jira guy but this customer that I was working with recently, had all its teams using Rally. …

Introduction

Image Processing and Machine Learning, the two hot cakes of tech world. Did you know that we are the most documented generation in history of humanity. Every minute a whooping 1.78 million GB data gets produced online !!!. That’s a lot of data and a big chunk that of data is images and videos. This is where automated image processing and machine learning comes in.
There never has been an more awesome time to be a geek. …

Vagrant is an wonderful tool if you have a need to provision throw away development envs every now and then. I usually use vagrant to provision vm locally for any new poc that I am working on and once all looks good locally, I can choose to throw away the local setup or archive it for future use.

Ansible is an python based, agent less, automation engine which is use to automate configuration management across various hosts remotely and securely.

Since vagrant gives me the option of spinning off throw away vms on the fly, its a good fit if…

This is the continuation of my previous blog where we learned, what is fourier transform and how application of high pass filter on fourier transform of an image can potentially help us with edge detection. In case you missed it, please find it here :

Edge detection in images using Fourier Transform

In this post we are gonna learn about two other types of filters and see how can they help us in image analysis :

• Low pass filter
• Band pass filter

Filters

I’ll quickly go over the the concept of…

Often while working with image processing, you end up exploring different methods to evaluate the best approach that fits your particular needs. I am going to talk about one such approach here, Fourier Transform.

What is Fourier Transform?

In the simplest terms, a Fourier Transform helps in breaking down an incoming signal into its building blocks. For example, consider a signal f(x) having made by superimposing two or more sinusoidal functions with different frequencies. Now by just looking at the plot of f(x) you won’t be able to decide what or how many original functions were used to form f(x).

This is where Fourier…

With the kind of pace that industry works in now, I don’t think that this even qualifies as a valid topic of discussion anymore. Of course automation is necessary. I myself started out as a build and release guy in IT and transitioned over to DevOps, so automation is kind of like my bread and butter. However in this blog, I would like to talk about the “side-effects”, if you will, that have been kicking in for past decade because of this rampant automation in IT and about.

Over the last few years that I have worked as an Automation…

Understanding CORS

CORS or Cross Origin Resource Sharing is an http mechanism to let a user gain access to resources located on a domain other that the one the site lives on by using some additional headers. So for example lets say your app located on http://test1.domain.com needs to make a REST call to an api located on http://test2.domain.com/some/awesome/endpoint.

Now By default a browser wouldn’t allow such a request. This is done for http security reasons. What that means is a browser wouldn’t allow a request made from within a script on a webpage to access any HTTP resources located on a…
