Virtual Private Networking (VPN) is a popular phenomenon in 2018. Seven years back we published articles to discuss about VPN. It is possibly obvious that in this seven years, many technologies has changed to an aspect that over 50% of the citizens of most of the countries has a 4G connection at home and a smartphone. Unfortunately, not all of them are enough knowledgably around basics of cyber … [Read more...]

Arduino Temperature & Humidity Sensor DHT 11 With LCD 1602A
Previously, we published guide on how to setup LCD 1602A with Arduino, print Arduino Temperature Humidity Sensor reading on serial display. This guide, simply combining those two guides in the same way we combined two guides on our Arduino basic light meter guide. In This Guide, We Will create a Arduino Temperature & Humidity Sensor DHT 11 With LCD 1602A Following Few Steps. A the end of this … [Read more...]
How To Convert LCD Display to LCD Serial Display For Arduino
In our older guides on LCD display, we have shown the initial 1602A LCD Display Arduino Connection (Blue Light White Text 16×2), added a LDR to use that display to show intensity of light. But, that way of interfacing with Arduino is too primitive and engages too many pins. It is high inconvenient for repeated use and does not give all the features. We have software serial monitor on Arduino IDE. … [Read more...]
What is Data Mart? Difference of Data Mart With Data Warehouse
In earlier publications on this website, we already discussed some of the basic, must to know matters around Big Data. Related to current topic they are Theoretical Foundations of Big Data, Data Lake, Data Refining, Difference Between Data Lake and Data Warehouse, ETL (Extract, transform, load) etc to mention a few. We often hear discussion around Data Mart. What is Data Mart? In simple language, … [Read more...]
Arduino With DHT 11 Sensor and Arduino Online IDE : Basic IoT
Whe we hear about IoT, we think about spealized hardware. However, basic IoT is obtaining the output of sensor over the Internet from your room. Using Arduino online IDE's serial monitor is actually primitive IDE, although does not sound highly interesting or special. The temperature humidity reading on Arduino online IDE's serial monitor is actually over the internet and with 4G/LTE connection it … [Read more...]
How Setup Private Docker Registry on Ubuntu 16.04 LTS Cloud Server
In series of our previously published guides on Docker, we discussed around using Docker. In those guides we used Docker's public repository to pull, push Docker images. We discussed about limitations of Docker Community Edition too. You Can Have Your Own Docker Registry on Own Cloud Server Instance with limitations of Docker Community Edition. Here is How Setup Private Docker Registry on Ubuntu … [Read more...]
Docker is Not a Free Software : Limitation of Community Edition
In case, your need as independent developer or small company demands extensive set of features including Docker Trusted Registry then the limitations of community edition will be apparent. Docker is Not a Free Software. Docker With All Components is Neither Licensed Under GNU GPL Nor Docker Community Edition Offers All the Features Which Developer or Small Company Will Need. That neither means … [Read more...]
List of Raspberry Pi Essential Accessories For The New Users
In our one old guide, we discussed in details how to setup and run Raspberry Pi from command line and list of Single Board Computers as alternative to Raspberry Pi. Unless You Are Running Raspberry Pi or Some Other Single Board Computer From Command Line, You'll Need Some Accessories. The listed things are bare minimum and one have to purchase along with Raspberry Pi or similar Single-Board … [Read more...]
Docker Vs Kubernetes Vs Apache Mesos : devOps Dilemma Clarified
Sometimes We Talk About Docker, Sometimes Combine Docker With Kubernates, Sometimes We Talk How to Install Meos. It is normal to get confused, specially the students at initial years who are self learning at own effort. Here is Docker Vs Kubernetes Vs Apache Mesos to Clarify devOps. Kubernetes, Docker, and Swarm are practically class of DevOps infrastructure management tools also known as … [Read more...]
Cloud Foundry Versus IBM BlueMix (IBM Cloud)
This topic possibly should be published long before when we talked about PaaS. New Users Often Seek Cloud Foundry Versus IBM BlueMix Comparison For Understanding the Tools, PaaS platform and Open Source Technology Behind. All possibly know that IBM Bluemix is a cloud platform as a service (PaaS) developed by IBM with integrated DevOps. Recently, IBM announced that they are merging the Bluemix … [Read more...]
Arduino DIY SD Card Reader and Cheap SD Card Reader Module
For Projects Like Arduino Door Bell We Need Some Extra Storage & Arduino DIY SD Card Reader and Cheap SD Card Reader Module Becomes Practical Matter. It is true that we can play MP3 with Arduino without SD card, but that has limitations. It may appear silly when cheap Made in China SD card readers avaible at $1.5 but actually DIY can save space or just great to test without much resource. This … [Read more...]
