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...]

Run Serverless for Free : GitHub Pages & OpenWhisk/IBM Cloud
Many users fear to test serverless because of unknown cost. Serverless is just hacked form of hosting HTML pages on Cloud Storage or CDN. This is an introductory guide to give the idea how we can test serverless with GitHub pages, PHP functions with OpenWhisk. IBM Cloud Serverless uses the same OpenWhisk. IBM Cloud provides many services for free of cost for testing. As OpenWhisk is a Free … [Read more...]
Difference Between Data Mining and Big Data Analytics
Data mining and big data analytics are the two most commonly used terms in the world of data sciience. Most of the newbie considers both the terms similar, while they are not. Previously, we described the difference between data science and big data, apart from publishing specific topics on big data and data mining. Data mining is the approach to find unknown relationships in data. Data Science … [Read more...]
Scope of ESP32 in Commercial IoT Products
Can ESP32 used in Commercial IoT products? Yes, ESP32 has modules and SoC to fit your production need. However, Arduino IDE is not for production. The reason we switched our projects from genuine Arduino to ESP32 Arduino is to broaden the scope. Our IoT guides are around IBM for highest compatibility. Node-red is the most popular IoT control software, which is very easy to use and many tutorials. … [Read more...]
