5 Ways Developers Can Have Multiple Income Streams
A couple of weeks back I was having a discussion with a former colleague who was upset due to no job and was not having some luck to find some freelance gig either. Another developer also had similar situation and despite of knowing something he was not able to get work. I have been working independently for 5 years. Prior to that I was engaged in typical 9-5 jobs. When you work solo, you should expect some tough time unless and until you have multiple revenue streams.

Year 2017 : Keep Reading, Keep Writing and Keep Learning
The year 2016 is almost over. It’s time to take a break from typical technical posts and talks about what was done and what to be done. 2016 was the year I got involved in many new things, new in a sense that I had left them long time back and resumed again.

How to optimize website speed and performance by using free tools
Developing a website is not enough these days. Even developing an “awesome looking” website is not only going to serve your purpose unless it loads faster and rank better on Google. In an earlier post I discussed how you can use free SEO Tools to rank better on Google but Google’s core search algorithm has been evolving continuously and now they are also taking site speed into consideration. For that purpose they are relying on their own tool called Page Speed which helps you to figure out what Google thinks about your website. The goal The goal is: how a developer, a front-end developer/designer or.. even a backend developer like me…

A few weeks back I was intrigued by Per Harald Borgen’s post Machine Learning in a Week which oversimplified the entire learning and implementing a Machine Learning algorithm in a week on a real dataset. He laid down the framework that how as a programmer one can get into ML thing without getting worried about heavy maths and statistics. It was a good excuse to give this ML thing a chance which I had been trying to do for many years after completing Coursera course. Alright. So on this Monday I started my mission. I had to find out some good dataset to achieve the task. Initially I wanted to use NASA’s meteorites…
