Does your Tech Lead complain of being pulled in multiple directions at once? Do they get frustrated about all the code they’re not writing? Being a Tech Lead can’t be easy, with all its context switching and plate spinning. For a developer, it’s a great achievement to progress to a Tech Lead role.

While our company and our application were constantly growing, we often ran into some consistency issues between code and design. Because we didn't have a design/frontend system and development guidelines to follow, our UI became cluttered and unsustainable.

Introduction: By nature HackerEarth has so many programming puzzles. These puzzles bound to have mathematical equations, statements and symbols. Problem Setters often requested us to add support for Latex. Implementation: The obvious and easy solution for this is to implement Latex support for individual pages. But that’s not scalable and maintainable. Then we came with up with a solution where we didn’t have to write custom code for eve....

Almost a success - 27 tracks uploaded for 31 days. All of them are in my Jamathon playlist. One (#17) was a cheat because it didn’t involve any apps but was a recording using binaural microphones. Favourites are marked thusly: ★ Jamathon #1: Created from a one minute recording of my bathroom fan Jamathon #2: Made with some previously recorded-with-Fieldscaper samples Jamathon #3: Samplr with various samples Jamathon #4: ★ Created from three..

We at HackerEarth regularly conduct 24-hours internal hackathons usually once a month to boost ourselves to get familiar with new technologies and to come up with great ideas and hacks to increase our productivity. A hackathon project can be anything from creating a new product to creating some tools which helps our own devlopment. In the hakathon in Dec 2015, I came up with the idea to create a profiler which could tell which code inside d....

Facebook recently announced the closing of parse.com which is disappointing but not totally surprising. Everyone knows a project from a large tech company can just shutdown in a blink of an eye leaving millions of users/developers in limbo. In that sense one of the questions that gets under my skin is what happens if Codename One calls it quits… You’d be better off than anyone who used parse and it’s far less likely to happen. Coden..
