  Proximity Cards Do More Than Just Open Doors

Credit: Susanne Plank via Pexels Locksmiths from centuries ago couldn’t have possibly imagined opening a door by tapping a card roughly the size of a credit card. Back then, security depended on physical locks, not sealed antennas made from coiled wire, integrated circuits, and capacitors. Today, proximity cards are a popular form of keycard used in hotels, government buildings, healthcare facilities, and many more places. They open doors for people with authorized access, but they also d...

  Pair Programming: The disadvantages of 100% pairing

I’ve written a lot of blog posts in the past about pair programming and the advantages that I’ve seen from using this technique but lately I find myself increasingly frustrated at the need to pair 100% of the time which happens on most teams I work on. From my experience it’s certainly useful as a coaching tool, as I’ve mentioned before I think it’s a very useful for increasing the amount of collaboration between team members and an excellent way for ensuring ...

  Unix Philosophy

First, let me tell two stories.The first one is one Japan soap factory had a problem that they sometimes shipped empty boxes to the customer without soap inside. So they spend much time and money to invent a X-ray machine to check whether the soap box is empty.The same thing happens in a small factory which doesn't have too much money. The solution of them to solve this problem is they use a desk fan to blow the empty boxes out of the belt and into a bin.The second story is NASA finds that in sp...

  10 Tools Every Software Developer Should Use in 2018

The main problem I noticed about most programmers is that even though they know about latest software development tools, they never really spend significant time to learn them well. As a programmer, I always try to learn new tools and latest technologies. At the same time, I also look to improve my knowledge of tools which I have been using for many years. Whether you're a front-end developer, full-stack programmer or part of a DevOps team, you should familiarize yourself with the latest develop...

  Dart is to JavaScript as C# is to C++

Given the background of Lars Bak, the Google engineer whose V8 JavaScript interpreter upended Firefox's claim on speed, it was reasonable to suspect Google's new Web development language might look a lot like Smalltalk. But that might have taken the Web in a strange and different direction. Today, on the day of a Web developers' conference in Denmark, Google and members of the Chromium open source development team raised the curtain on Dart, the company's bid for a new and somewhat more str...

  Why so many Python web frameworks?

When asked about the plethora of web frameworks for Python the answer is often that it is way too easy to put together one in Python. That certainly seems plausible since there are so many libraries that implement the components of a web framework and if it's easy to plug those pieces together then maybe that lowers the bar of entry for new frameworks. So let's give it a shot, we'll pick some components and spend a couple hours seeing how far we can get building a web framework, which we...
