Apache Edgent is for edge devices to analyze collected data by the device. Apache Edgent is a programming model and micro-kernel style runtime which can be embedded in gateways which makes it easy to process sensor streams on edge devices like Raspberry Pi and run local analytics, then send only useful information to server. Apache Edgent's old name is Apache Quarks. The tool is excellent for … [Read more...]

1602A LCD Display I2C Serial Interface (Arduino)
Previously, we shown how to setup 1602A LCD Display with Arduino. The units of 1602A LCD I received, is really of good quality. You noticed in that guide we had use huge number of wires occupying many pins of Arduino. That is not good, specially for when Arduino running with ATtiny - if one display occupies so many pins then many projects becomes difficult to make real. We can use a module/IC for … [Read more...]
How To Install Apache Flink on Ubuntu Server
Apache Flink is a big data processing engine which can run in both streaming & batch mode. data Artisans is the company who is the original creator of Flink. It started as a project called Stratosphere, which was forked, and became Apache Flink. Flink can be deployed on local machine, on cluster (it can run on YARN), or can be deployed in the cloud. Core of Apache Flink is a distributed … [Read more...]
How to Write Arduino Library of Your Own
Normally, we write sketch on Arduino IDE, which essentially uses libraries. Library of Arduino is Set of Instructions to Avoid Repeated Huge Coding. As we discussed in how to learn Arduino programming, C++, C are important languages are important to learn for Arduino and embedded systems. Libraries add an abstraction from reality - which is practical for using things like a temperature humidity … [Read more...]
Resources For Learning Electronics in Official Arduino Website
Arduino, WordPress, Debian apt repository, OS X Homebrew - all appears just easy from front end. Free Software culture tries to give Freedom to users in the way Richard Stallman described. Like Any F/OSS Project, Arduino Also Not Newbie Friendly to Find Resources. The reason of unorganized structure of documentations is for a basic fact - none actually make huge money from any F/OSS project. There … [Read more...]
What is TTL? – Transistor-Transistor Logic
In our some previous articles, in context of Arduino for beginners, we discussed about serial connection, UART, SPI, I2C protocol. Another commonly heard phrase is TTL. What is TTL? Transistor-Transistor Logic or TTL is a family of logic circuits used in electronics invented in the 1960s. We will try to keep the article as brief and easy as possible. What is TTL? TTL is a … [Read more...]
IBM Continues Mainframe Making Them Smaller in Scale
The New Models From IBM Can Fit into 19-inch Racks Efficient For Building New Generation Cloud Infrastructure. IBM has unveiled two new models from its current z14 mainframe line, released last year. IBM Continues Mainframe Making Them Smaller in Scale Like We Predicted Before. The most striking feature of these new is their small size. These compact models z14 ZR1 and LinuxONE Rockhopper II were … [Read more...]
Integrating Apache Nutch With Apache Solr on Ubuntu Server
In our previous tutorials, we written the steps to install Apache Nutch on Ubuntu Server and also how to install Apache Solr on Ubuntu Server. Integrating Apache Nutch With Apache Solr Will Offer a Web UI, Options to Visually Search and Use Extended Functions of Apache Nutch. Our guide on installing Apache Solr uses older version of Solr (at present). We are using Apache Nutch 1.x - in previous … [Read more...]
