Frontend asset management in rails applications

Algorithm Analysis: Best, Worst and Average Case

Algorithms are a sequence of decisions we make to solve a problem. Like every decision in life we can make great decisions and really terrible decisions. But it doesn’t end there. Good decisions vary, they can come easy and can take a lot harder process to reach an expected outcome.

Thoughts on Semantic Styling vs Visual Styling

Using version managers and virtual environments

It’s a new year and 2015 was a blast for me. I successfully ticked every item on my list for 2015 and I had even more that I hadn’t expected from the start of the year. In July, I got an email from PacktPub about reviewing a book on building GUIs with Python. The opportunity was influenced by the article I’d written on the subject and I’m glad I did. The book was completed and published in December and I got really excited to see that I’m a part of something that’ll impact the lives of people around the world. It is available on Amazon and PacktPub and I urge you to grab a copy as there’s so much to learn from it.

What happens when using CSS frameworks

I’ve always been an anti-css-frameworks person for no reason till I finally got a good reason recently.

I love design and development and I wouldn’t allow learned helplessness or people’s opinions to keep me from exploring either of them to my satisfaction.
