A File Hosting Service is an online service of file storage system which allows the users to store their files (which are static content, mostly large files, and are not web pages) over the Internet or a corporate network on a central data store and access them via a client or web browser. Most of the cloud storage services allows to host web pages, for example Rackspace Cloud Files, IBM Cloud and … [Read more...]
What is Multitenancy?
Multitenancy is a software architecture principle in which a single instance of the application runs on the server, but multiple clients or organizations (fork or instance) are being served. This model differs from multi-instance architectures where each organization or client has its own installed instance of the application. With a multi-tenant architecture, your application can virtually … [Read more...]
ESP32 as Hardware Random Number Generator
The capability of the ESP32 to generate truly random numbers is important for cryptographic operations. A random number generator generates a sequence of random numbers. A hardware random number generator is also known as a true random number generator. It generates random numbers from some physical process, not from code. A fundamental distinction is made between non-deterministic and … [Read more...]
How Server-Based Gaming (SBG) Works
The casino industry uses the server-based gaming (SBG) hardware system to operate Video Lottery Terminals slot machines. General non-casino gaming systems differ from the casino systems in various ways. Server-Based Gaming (SBG) is built upon the server-centric gaming technology borrowing the principles from thin client. Reliability, scalability and stability are few of the requirements in the … [Read more...]
IoT IR Remote Control with ESP32 Arduino and IBM Watson IoT
In this article, we are discussing the overall hardware, code and library we will need. This article is not about building one particular project. Infrared (IR) remote control technology is widely used in day to day used devices. IR remote control signals are a reliable resource to control nearby electrical appliances. With the development of ESP32 like cheaper system on chip and Internet of … [Read more...]
How to Run an ESP32 on Battery
The operating voltage range of ESP32 is 2.2V to 3.6V. The ESP32 boards have an LDO voltage regulator to keep the voltage at 3.3V. The output of the regulator is also broken out to one of the sides of the board and labelled as 3V3 which can be used to supply power to the other components. The VIN pin can be used to directly supply the ESP32 a regulated 5V voltage electricity supply. In other words, … [Read more...]
Strategic Benefits of “as-a-service” with Hybrid Cloud
To maximize the benefits of hybrid cloud infrastructures, we can consider the as-a-service services of specialized providers for the management of these mostly highly complex IT infrastructures. By leveraging cloud infrastructures, organizations save costs, become more agile, and drive innovation faster. This is also shown by various surveys. Many of the IT decision-makers see it as a prerequisite … [Read more...]
Call for Code 2020: Coding Challenge to Save Mankind from Pandemics
Call for Code is a coding competition. We talked about Call for Code in the year 2018 and 2019 too. It is a multi-year initiative with 5 years commitment from IBM. To the developers, Call for Code is a chance to use the latest technologies to create a long-lasting cost-effective solution. In this year’s Call for Code Challenge, one of the themes is to mitigate the impact of global pandemics like … [Read more...]
ESP32 vs Arduino : How ESP32 is Different from Arduino
ESP32 is a low cost, low power consuming System on Chip (SoC) with integrated Wi-Fi and Bluetooth compatible with Arduino IDE. In other words, an ESP32 board can be used as "Arduino" following some guide like we have published one in the past. ESP32 is developed by Espressif Systems and has a Tensilica Xtensa LX6 microprocessor. By the phrase "Arduino", we mean the boards which are designed and … [Read more...]
How the Post-Quarantine Era Will Be for the IT Workers
The quarantine measures for coronavirus pandemic was an apt measure to control it. However, its impact already has been obvious to the whole world from an economic perspective. Quarantines travel bans, and home-stay resulted in a decline in consumer spending. Many businesses are operating at a loss. While many startups are struggling to close. These factors are resulting in unemployment and … [Read more...]
How To Increase Your Website’s Domain Authority
Domain Authority (DA) is a numerical value ranging from 0-100 to reflect an idea of how well a website will rank on Google web search and possibly other web searches. It was developed by Moz. The Domain Authority (DA) of a website points towards the relevance for a specific industry. In the beginning, Google made the PageRank (PR) public which unleashed a flood of optimization strategies. There … [Read more...]
