5 tips to be a Better Programmer

Here are five tips to be a better programmer.

  1. Coding is a craft; you learn it by doing it. That is why training courses have such a strong practical element. It is also a skill that is easy to forget, so use it or lose it.
  2. Even when familiar with the basic constructs, it is still worth fully understanding the detailed syntax of the language you are using. Languages contain many subtleties.
  3. Learn some theory and then do some practical. First gain a good understanding of the principles, purpose and limits of a new technology. Next, start to build an application using the technology.
  4. Many developers start to build something, and may even get it to work, without really knowing what exactly they are doing, or why. That is why having a good understanding is important. With software development, theory and practice go hand in hand.
  5. For the practical bit, it is fine to start by copying code or following step-by-step instructions. But then try, by yourself, building a program from scratch. That is when you really get a sense of achievement.

Amazon Unveils its Eighth Generation Fulfillment Center in USA


Amazon revealed its newest generation fulfillment center utilizing robotics, vision systems and high-end technology to speed up order delivery times for customers on last Cyber Monday (December 01, 2014)

“The Amazon fulfillment teams are dedicated to innovating in our fulfillment centers to increase speed of delivery while enabling greater local selection at lower costs for our customers. The advancements in our latest fulfillment centers hit all three of these customer desires while continuing to provide a work environment that is great for employees,” said Dave Clark, Amazon’s senior vice president of worldwide operations and customer service.

Some features of Amazon’s eighth generation fulfillment center include:

  • Kiva robots of which Amazon currently has more than 15,000 operating across the U.S.;
  • Robo-Stow, one of Earth’s largest robotic arms moving large quantities of inventory for customer order fulfillment;
  • New vision systems enabling the unloading and receipt of an entire trailer of inventory in as little as 30 minutes instead of hours; and
  • New, high-end graphically oriented computer systems for employees to use while fulfilling orders for customers.

Amazon recently announced it will hire 80,000 seasonal employees to fulfill customer orders this holiday, a 14 percent increase over last year. The company expects that thousands of those employees will stay on in regular, full-time roles.
