How to Use pgrep and pkill Command

On unix-like OS, the pkill command sends a signal to the processes while the pgrep command searches for processes currently running on the system. Originally, the pkill was written for using with the Solaris 7 (1998). kill, killall, pkill, pgrep can be used on all the GNU/Linux OS, MacOS X and Linux shell on Windows 10. The kill signals HUP (1) reloads a process, KILL (9) kills a process, TERM … [Read more...]

The Relationship Between BPM and BI

Only a few years ago, business process management (BPM) was an important strategic task for corporate management. Today, interest has waned due to rampant planning and modelling. Instead, digitalization is better tackled. Today, new business models and processes are being created, while existing processes and areas are being restructured and digitized. The short time horizon in which processes are … [Read more...]

How to Drive Innovation in Your Business

What the companies have to do to drive innovation? Innovation is the implementation of new ideas that create value. There are four aspects with different weightings to get into the right innovation process, namely the purpose (10 percent), i.e. the transformation of business, the use of new markets or new technologies; the processes (20 percent), such as the focus on adjacent value creation areas, … [Read more...]

5 Software Ideas for Employee Management

Creating a motivated, productive workplace is no mean feat. Some would argue that it’s getting more and more challenging for CEOs and managers to increase the general performance of their team. Of course, when time equals money, low productivity can harm the profitability of the business. The good news is that technology can help you revamp your employee productivity, and take some of the burdens … [Read more...]

How to Install JDK 8 on Windows

In our one guide we have shown how to install JDK 11 on Windows. JDK 8 is often among the prerequisites of various developmental tools. In this guide, we will discuss the steps to correctly install JDK 8 and configure the PATH. Basics on JVM has been already discussed and we will not repeat. Often, many of the developmental tools support specific version of Oracle JDK (same goes to JDK from the … [Read more...]

What is Asymmetric Cryptography?

Asymmetric cryptography or two-key cryptography is the cryptographic method that a pair uses of keys for sending messages. The two keys belong to the same person who will receive the message. One key is public and can be delivered to anyone, the other key is private and the owner must keep it so that no one has access to it. In addition, cryptographic methods guarantee that this key pair can only … [Read more...]

Traffic-Sign Recognition : Basics

Traffic-Sign Recognition (TSR) is a part of Advanced Driver-Assistance Systems (ADAS). Traffic-Sign Recognition (TSR) helps the vehicles to recognize the traffic signs on the road. The signs can be speed limit, school children, turn ahead, speed breaker and so on. The Traffic-Sign Recognition systems are increasingly being used for road traffic safety by helping the drivers by automatic alerts on … [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...]

ESP32 Arduino : What is SPI Flash File System (SPIFFS)

The SPI Flash File System or SPIFFS is a light-weight file system for microcontrollers with an SPI flash chip. A flash file system is designed for storing files on flash memory–based storage devices optimized for the particular system. SPI stands for Serial Peripheral Interface. Flash memory is a type of non-volatile storage that is electrically eraseable and rewriteable. Flash memory is a kind … [Read more...]

Kalman Filter to Stabilize Sensor Readings

Kalman Filter Commonly Used to Stabilize Sensor Readings. The Kalman filter reduces the errors of raw measurements, provides estimates for quantities. The Kalman filter is widely used in robotics, navigation, GPS, biomedical, electronic control circuits of ubiquitous communication systems such as radio and computer. It is a mathematical model which can be applied as a snippet. The Kalman filter is … [Read more...]

What is HTTP POST Method?

In some previous Arduino guide, we used HTTP POST method to upload sensor data. What is HTTP POST? HTTP POST is used to send data to a server to create or update a resource where the URL already existing. In the same way, we used HTTP GET with WordPress, HTTP PUT with OpenStack Swift. First, we need to understand what is HTTP POST, second we need to know basic difference with simillar methods such … [Read more...]
