The CAP theorem or Brewers Theorem states that in a distributed system it is impossible to simultaneously guarantee the three properties - Consistency, Availability and Partition tolerance (failure tolerance). According to the CAP theorem, a distributed system can meet two of the following properties at the same time, but not all three. The consistency of the stored data. In distributed systems … [Read more...]

Wi-Fi for Old House With Thick Walls
Residents of old houses with 2 to 3ft thick limestone exterior walls and some load-bearing interior walls often face problem while deploying Wi-Fi to their houses. Most of these walls were insulated and it is super difficult for any radio-wave to penetrate. While these buildings are good for health while deploying solutions related to the Internet of Things invite a lot of problems. Height of most … [Read more...]
What is Inertial Navigation System?
An inertial navigation system (INS) is a 3-D measurement system with an inertial measurement unit as a central sensor unit with several accelerations and rotational rate sensors. By integrating the accelerations and rotation rates measured, the spatial movement and the respective geographical position is continuously determined. The main advantage is that it can be operated without reference, i.e. … [Read more...]
What is Miniaturization?
Miniaturization is a process for shrinking structures while maintaining the function and possibly also the shape. In technology, this means the continuous reduction of various components of technical devices. It has been a target of many developments in science and technology for about three decades. As driving moments, desires for increasing performance and speed are most important, as well as … [Read more...]
What is Domain-Driven Design (DDD)?
Domain-driven Design (DDD)is an approach to model complex software. The modelling of the software is significantly influenced by the technicalities of the application domain to be implemented. The term "domain-driven design" was coined by Eric Evans in 2003. Domain-driven design is not just a technique or method. Rather, it is a way of thinking and prioritizing to increase the productivity of … [Read more...]

Arduino : Independently Blink Multiple LED
A practical question which comes up every day is how to blink two LEDs at different rates? That simply means an independent control on each LED. That small wish is a big jump to visual animation. In real life, the multi-coloured Christmas lights (aka Dewali lights) blinks in that fashion to give us a great feel. Problem to most of the beginners is with the usual "blink" tutorial program … [Read more...]
What is a Loosely Coupled System?
In computer science, loose coupling denotes a low degree of dependence on hardware or software components on each other. When a system is loosely coupled, it is often easier to make changes to individual components because the change has only a local effect. If there were a close coupling, the change would not remain local but would require additional adjustments in all coupled components if … [Read more...]
How To Repack Installed Software on Debian/Ubuntu
It can happen that a particular version of a specific tweaked package no longer available elsewhere or you want the exact "clone" of the running software. If you have installed some Debian package on your server and want to install the same package on another server either to avoid downloading them again or "clone" with the settings then there are some tools which can help you. If the second … [Read more...]
