Big Data analytics provides meaningful analysis of a large set of data. All of these software help in finding current market trends, customer preferences, and other information. While choosing the solutions, we should keep in mind that some Big Data platforms are/were specifically designed for professionals who know how to work with similar platforms. At the same time, some software has a very … [Read more...]
Cheap ESP32-CAM Setup With Arduino IDE
Here are Minor Details of Cheap ESP32-CAM Setup With Arduino IDE. In an earlier guide, we described the steps to setup the normal variants of ESP WROOM 32 with Arduino IDE on Windows PC. The software setup part is essentially the same for these cheap ESP32-CAMs too but there is more hardware to buy with it. This board has an OV2640 camera and a microSD card slot. Obviously, OV2640 camera … [Read more...]
How to Take Sharp Photos With DSLR
It is the lens which makes the photos razor sharp. There are many blog articles on how to take sharp photos with DSLR cameras but without a proper lens, you can not test them. For an average camera with standard zoom lens, like Sony A68 with 18-135mm kit lens, you will not get sharp close-up photos of flowers. There will be a deficiency in sharpness. Sony 18-135mm kit lens is enough great but it … [Read more...]
Guide to Gap Analysis
Gap analysis is a topic related to management. Gap analysis is a management tool for early detection of vulnerabilities. Gap analysis is a systematic way to improve the efficiency for strategic and operational purposes. In other words, it is the comparison of actual performance with desired performance. The gap analysis provides a rough overview that can be used for in-depth analysis, for example, … [Read more...]
Controlling AC Powered Appliances With ESP32 and IBM Watson IoT
It is an upgrade to our previous article to control ESP32 Arduino LED from IBM Watson IoT. We already talked about Android Apps for Watson IoT for this purpose. We already have an article to use relay with Arduino. Our linked relay guide should be enough for anyone to understand how to use relay and AC connections. These relay modules will create mechanical clicking sound like switch. My relay … [Read more...]
Android Apps to Control Devices Connected to IBM Watson IoT
It is too common to find some ready to use Android app which can perform basic works, such as some apps which can work to control ESP32 Arduino LED from IBM Watson IoT. As for receiving notification from IBM Watson IoT platform, we previously described one app named Pushover for push notification after routing the backend on Node-RED. However, for our previous guide to control ESP32 Arduino … [Read more...]
GPS Spoofing : Risks From Hacked GPS Systems
Positioning by satellite is an indispensable part of private life and business. The Global Positioning System (GPS) is one of several networks of global navigation satellite systems (GNSS). It serves primarily to determine the position. But GPS is actually vulnerable. In many of the industries, the GPS technology is used in products and services. Automotive manufacturers use it for their … [Read more...]
Static Website with Jekyll, Object Storage and OpenWhisk Serverless
This article is mostly for providing the idea of how in the last 10 years we are progressing to host small websites on free to cheaper cloud storage. Many readers are Most of the peoples with some work over the internet are used with Jekyll and OctoPress. They are static site generator and also management tool. So far, we could host our static websites on various platforms including Object … [Read more...]
Does Serverless Computing Offer the Benefits of Microservices?
Often this kind of question arises in the mind of who are new to the world of cloud computing. We have discussed some basic around serverless including What Problems are Solved by Serverless, Relationship Between Serverless Computing and Microservices, What Is a Serverless Microservice and so on. Serverless is an excellent environment to build a microservices architecture due to optimal … [Read more...]
Control ESP32 Arduino LED from IBM Watson IoT
Anthony Elder published a guide on developerWorks Recipes on how to "Build your own Watson controlled kettle" for ESP8266. This article's code is shamelessly ripped-off from him for broader usage. This guide will show how to turn on and turn off a LED connected with ESP32 Arduino from IBM Watson IoT platform. That "remote control" over the internet will be shown by using a simple bash scripts - … [Read more...]
