For this guide we have to use IBM Bluemix. In our previous guides we talked about how to use Jupyter Notebook, IBM Data Science Experience software, How To Run Docker, Containers On IBM Bluemix, Jupyter Notebook on IBM Bluemix in old way, Python libraries for Data Science, a WordPress Plugin showing usage of Watson Tone Analyser, cognitive data analysis etc. These things are modern and often … [Read more...]
New IBM Cloud Private Software Based on Containers, Microservices and APIs
5 years bak, condition of IBM was not exactly in great condition around cloud. When IBM started Bluemix PaaS, Heroku like PaaS was more acceptable. It is practical fact, today with data sciences, big data, PaaS; IBM has lot of things to offer. Their major deficiencies was possibly understanding the need of the developers. IBM recently announced open source Grafeas project to help developers with … [Read more...]
Arduino MAX 7219 CNG Basic Circuit : LED, 7 Segment Displays
MAX 7219 and MAX 7221 quite commonly used display driver IC for LEDs. Actually the same IC was in the 8x8 LED Matrix display. Right now, we know about 7 segment LED display as electronic component and multiplexing (increasing the number of digital pins in Arduino). Here is how to create Arduino MAX 7219 CNG basic circuit to control LED, 7 Segment displays in own custom ways rather than using … [Read more...]
Social Impact of Big Data : Part 2
In first part of Social Impact of Big Data, we discussed about the sources from which data are collected. In this article on second part of social impact of big data, we will discuss about the commercial usages and applications of big data and big data analysis. From that previous article, it is obvious matter that caution should be exercised when processing, storing or generally using data … [Read more...]
How to Use Python on Arduino, Like to Blink LED?
We can directly use C++ on Arduino instead of using Arduino's default way. Also, we can code with C on Arduino. As readers possibly know - Arduino does not have any special language. But, How to Use Python on Arduino, For Tasks Like to Blink LED?. We need not to compile the Python scripts unlike C++ but simply run the Python scripts from Terminal/iTerm2. That is not exactly great, but kind of … [Read more...]
How to Manage Logfiles with Logrotate
In many guides on this website, we talked about log rotation. Logrotate is Linux utility for automatic rotation, compression, mailing log files etc jobs. Here is how to manage logfiles with logrotate. Many common programs automatically setup Logrotate. Like when we install Apache2, that adds a configuration file used by Logrotate to rotate all apache access and error logs/etc/logrotate.d/apache2. … [Read more...]
Fundamentals on Hovering Data Cloud
From the basic idea of communication between cars, the concept of Hovering Data Cloud system developed. This article is named Fundamentals on Hovering Data Cloud as the basic is being discussed for clarifying concept. The formation of congestion on highways has several causes. For one thing, there is no centrally controlling entity. As a result, every road user drives his personal driving … [Read more...]
