It is important to understand that DevOps is not hype. In our earlier articles, we discussed about Basics of DevOps, Analysis of Docker in DevOps, Analysis of Jenkins for DevOps and finally the article before this one - DevOps and Containerization Tools. The linked articles are enough descriptive to provide an idea about DevOps to a beginner. There are different advantages which can be gained … [Read more...]

Computer and Internet is catchall section of core computing categories including Cloud Computing, Digital Photography, Virtualization, Networking, Protocols and Others' which are not otherwise more subcategorized. Here also you will get unique articles and news on computer hardware, Software, Networking and Protocols.
What is a Virtual SIM?
Virtual SIM is a cloud-based mobile service number which can be used from any device using application or code. In an 8 years old previous article, we discussed about SIM card. Virtual SIM is software based cloud service. Unlike the traditional SIM cards, virtual SIMs are not physically attached to a mobile. SIM cards are chips which help the mobile networks operators to control fees for … [Read more...]
M5Stack (ESP32 Arduino) : Modular, Stackable, Wearable IoT Platform
The M5Stack is ESP32 Arduino by heart. It is a modular, stackable, wearable IoT platform for development which is obviously Open Source. There are many stackable ESP32 or other 32 bit Arduino compatible prototyping boards. The big difference of M5Stack with them is that it has an enclosure, display, pushbuttons, microSD card slot, USB-C, loudspeaker, and extension connectors. Official website … [Read more...]
What Are the Drawbacks of Kubernetes?
Without doubt, presently Kubernetes is the strongest container orchestration system. After Docker, Kubernetes redefined the scope of containerization. Docker has a hype part, it is really a moderate set of wrapper capabilities around the Linux kernel. Kubernetes is used for automating application deployment, scaling, and management. Kubernetes works with a range of container tools, including … [Read more...]
DevOps and Containerization Tools
Modern professional developer's life no way restricted within the coding. We continuously talk about Docker, Kubernetes, serverless, unikernels, CI/CD software (like Jenkins, Travis), tools automating the infrastructure (such as Chef, Puppet, Ansible, SaltStack), monitoring application performance (such as ELK, Prometheus) in this website because blogs of our IT sponsors talk about the … [Read more...]
Differences Between Batch Processing and Stream Processing
There are readers who are trying to understand Big Data, Data Science and data analytics. They are sometimes confused to differentiate stream processing and batch processing. Hadoop refers to an ecosystem which contains MapReduce. Batch processing is processing with a large volume of data at once. Batch Processing stores data in a disk. Then process them using MapReduce technologies like … [Read more...]
Butane Gas Blow Torch Welding for DIY Projects
Gas blow torch is a common tool used in metal works. Many of the metal things we use, buy use this simple tool. Here is a basic guide to the required tools for butane gas welding. Copper tubing, aluminium boxes are common materials which needs soldering. In an earlier guide we talked about cutting and drilling tools. With all the hand tools and an inkjet printer, it is possible to convert a 3D … [Read more...]
Serverless Computing : What Problems Does it Solve?
In our earlier discussions around Serverless, we talked around why some developers love Serverless. Serverless Computing does not solve any problem all at once. Let us go Serverless is towards a joke, in sense if the function is active all the time or demand is too much resources, traditional cloud server will be still cheaper. Current cost to run ordinary website (like, a less visited personal … [Read more...]
ESP32 With DHT11 Deep Sleep : Part 1
Here is part of ESP32 with DHT11 deep sleep guide explaining the basic behind code. Our DOIT ESP32 board (which we commonly use in examples on this website), not energy efficient for deep sleep. However, it works. We already can connect normal Arduino UNO with DHT 11, with ESP32 Arduino and also we can use the setup to send data to IBM Watson IoT. ESP32 offers us deep sleep mode for power … [Read more...]
Fix : gsuite username is a reserved word Error (postmaster, abuse email)
Recently we needed to use postmaster email address and came to knew that Google spies postmaster, abuse and some other emails of your domain. Our need to use "postmaster@thecustomizewindows.com" was for Adobe Creative Cloud. Of course, we could use some other email. Someway, "postmaster@thecustomizewindows.com" email got activated for one premium plan ( "admin@thecustomizewindows.com" was … [Read more...]
What is Infrasound? How Human Reacts to Sub 20Hz Infrasound?
Sub 20Hz sounds are infrasound and commonly we need special electrical system to pick up the sounds of that range. Infrasounds are low frequency sound waves. They are both mechanical vibrations and acoustic oscillations. They are usually below the threshold of sounds perceptible to the human ear (between 0 Hz and 16 to 20 Hz approximately) At lower frequencies, for physiological reasons, they are … [Read more...]
