How to Use Special Keys in UNIX

UNIX operating system has some special keys. These you can use to interrupt the program processing or to resume it. The file management and keys totally different in UNIX kinds of operating systems. 



An example of a UNIX special key and its use.
Why You Need Interruption
A scenario where you made some mistake in the input command and you need to stop the further process. Then you can use the CTRL+C command. It is equal to the DELETE command.

List of UNIX Special Keys


RETURN key — The RETURN key signifies the end of a line of input. On any terminal, RETURN has a key of its own, or return may be typed by holding down the control key and typing a 'm'.Ctrl-m
Hint: Ctrl-m command is equal to RETURN key in Unix systems

Hint: Ctrl-c Command you can use to interrupt the process.


Ctrl-s: Ctrl-s pauses the output and the program is suspended until you sta…

IoT Healthcare: Top Skills You Need

IoT and multimedia technologies have made their entrance in the healthcare field thanks to ambient-assisted living and telemedicine.

...

Smart devices, mobile Internet, and Cloud services contribute to the continuous and systematic innovation of Healthcare and enable cost-effective, efficient, timely, and high-quality ubiquitous medical services.


Skills You  Need Data Analytics Cloud Computing Security Smart Device


"Pervasive healthcare applications generate a vast amount of sensor data that have to be managed properly for further analysis and processing." The adoption of Cloud in this scenario leads to the abstraction of technical details, eliminating the need for expertise in, or control over, the technology infrastructure, and it represents a promising solution for managing healthcare sensor data efficiently.

It further makes mobile devices suited for health information delivery, access and communication, also on the go, enhancing medical data security, availability, and redundancy.


Moreover, it enables the execution (in the Cloud) of secure multimedia-based health services, overcoming the issue of running heavy multimedia & security algorithms on devices with limited computational capacity and small batteries. 

In this field, common issues related to management, technology, security, and law have been investigated: interoperability, system security, streaming Quality of Service (QoS), and dynamically increasing storage are commonly considered obstacles.

The IT skills greatly you need are:
  • Data analytics
  • Cloud computing
  • Smart devices applications
  • Security

Python Function: How to Write Error Logic

Image
Python is one of the top programming languages. Python does support Functions. While writing functions you also need to consider some errors. Those are called exceptions. I am explaining how to give error logic in a function of Python.



Exception-handling means to have logic for error scenarios. Writing exception I will show in a simple Function.

In this post I will give you syntax for writing function and exception. 
Here is my simpleFunction that multiplies two numbers.
Logic to write Function in Python to Multiply Two Numbers 
def product (num1,num2): prod=num1*num2 print( ' The product of the numbers is \t: '+str(prod)
Parameters used the Python Function
 The 'def' means you are defining function with a name of 'product'.In the parameters of 'product', you can see TWO variables. Those are to take input from the user for multiplication.prod=num1*num2. That means product of two numbers assigning to 'prod' variable. Python is dynamic language and you no ne…
