Kumar completed the $1 challenge yesterday. He wanted to learn Java and so he enrolled in a professional course in Bangalore. While doing the course he realized that many people around him were also looking for a similar course and the training institute had a referral policy. So, he asked them to join the same course. In a few days, 17 of them got enrolled and he earned a referral bonus of Rs. 17,000. Understand this. He didn't search on the internet "How to earn Rs. 17,000 easily?" He didn't have a roadmap for earning money. But he had an idea that acted as his vehicle. And that was enough. These days roads and roadmaps are easily available. But after spending some time on the road, holding a roadmap, you realize you can't walk to your goal. So, you look for more roadmaps in the hope of finding a shorter path. And that makes a bad situation worse. A car-like system can help, as it will get you started and keep you moving comfortably towards your goal. Once you have it, it is easy to reach the places you always dreamed of. Today, figure out how will you get such a system.

I’m happy to share this Delight Kitchen project I worked on. This was done as part of the project phase at #CDAC ACTS Pune and is a collaborative effort of me and my highly talented classmates . Each one of us worked on the full-stack, and did not limit ourselves to only back-end or front-end technologies. The tech stack that we have used on the project includes #MySQL, #SpringBoot, #ReactJS along with #ReactRedux and a mix of #Tailwind and #MaterialUI for responsive design. I specifically model the #entities, wrote of some of the #CRUD #APIs along with the admin #dashboard . The most fun part about the project was the learning we had while implementing it. Just to state an example - I encounter a new exception while writing the backend - #InvalidDataAccessApiUsageException - caused by passing a null reference to #Jpa findById method. I first looked for the Exception in the spring #documentation. To me it was not of much help as the exception turned out to be a generalized one rather than a specific exception. I then started trying different value to pass to the findByValue method as I knew something was going wrong with it. I found that null was being passed to the method in the #service class, but the values were passed to the #service by the #controller. I then looked in the #controller and spotted that the incoming data in request body was not being #unmarshalled by #spring. It turned out that @RequestBody annotation was imported from #swagger instead of #spring. Bringing in the correct imports fixed the issue
