How To Install TeamViewer on Linux Mint 21 - idroot
In this tutorial, we will show you how to install TeamViewer on Linux Mint 21. For those of you who didnât know, TeamViewer is an application that lets you access other computers remotely such as desktop sharing, online meetings, web conferencing, and file transfer between computers. TeamViewer is available for Microsoft Windows, Linux, macOS, iOS, and Android operating systems.
This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add âsudoâ to the commands to get root privileges. I will show you the step-by-step installation of the TeamViewer remote desktop on Linux Mint 21 (Vanessa).

How to load test your websites with Apache Bench | TechRepublic
How well are your websites performing? You might open a web browser, point it to those sites, and verify theyâre working, but do you really take the time to load test those sites to see if they are living up to the high-performance standards your business (or clients) require? If you donât know the answer to that question, you need to start load testing the sites you develop or administer.
Before you think this is challenging or will require paying for a third-party service, think again. There are plenty of tools to help you get this job done, many of them open-source and free. One such open-source tool is called Apache Bench.
Apache Bench is capable of load testing more than just the Apache web server, as any HTTP server or even an API (application programming interface) can be tested with this tool.

You Can Now Install KDE Plasma 5.25 on Kubuntu 22.04 LTS, Hereâs How - 9to5Linux
The wait is finally over! Kubuntu 22.04 LTS (Jammy Jellyfish) users are now able to the latest and greatest KDE Plasma 5.25 desktop environment on their personal computers.
Kubuntu 22.04 LTS was released in late April 2022 and it shipped with the long-term supported KDE Plasma 5.24 LTS desktop environment, which is obviously the smart choice because the KDE Project will support it with regular maintenance updates for two years.
But, thanks to the Kubuntu Backports PPA effort, if you want to enjoy the latest and greatest features, you can now upgrade your installations to the KDE Plasma 5.25 desktop environment, as well as the KDE Gear 21.12 and KDE Frameworks 5.95 software suites, which are all compiled against the Qt 5.15.3 framework.
To install KDE Plasma 5.25 on your Kubuntu 22.04 LTS machine, you will first need to ensure that you have all the latest updates installed so run the following commands in a terminal emulator, such as Konsole. Alternatively, you can use the Plasma Discover graphical package manager to apply all available updates.

How to Control Servo Motor with Arduino
Servo Motors is a type of electrical device which can change or rotate position of an object with great precision. In starting they were used to control RC plane wings moments later they made their way to robotics, humanoid robots and many automation projects. Unlike stepper motors their motion is limited between 0o to 180o.
Usually, servo motors have arms that can be controlled using Arduino. Servo motors consist of a control system which provides feedback about the current position of the motor shaft this feedback allows to move at great precision.

Monitor Raspberry Pi Information Through Mobile
Raspberry Pi Monitor is an Android application used to monitor your Raspberry Pi device on your mobile phone. This application will find information like CPU usage, device temperature, system memory, disk usage, and much more. You will also get to see these results in the form of graphs as well to find out how the information changes with each passing time.
In this guide, we will show you how you can install Raspberry Pi Monitor on your Android phone and monitor Raspberry Pi on it.

What does Vcc Stands for in Arduino
Vcc is any regulated DC voltage supply that is needed to operate an integrated circuit and sometimes also referred to as supply voltage for ICs. Mostly, Arduino are designed to operate at either 3.3V level logic for less power usage or at 5V logic for devices that are compatible with TTL logic. Vcc also known as (Voltage Common Collector) in any electrical circuit refers to a higher voltage value with respect to GND. Vcc may be positive or negative but in the case of Arduino it only operates over positive Vcc. Giving negative voltage to it can cause damage to the board.
Every electronic device needs power to run, the same is the case with Arduino. Vcc is the minimum power needed to operate Arduino efficiently. Vcc in Arduino refers to a regulated DC supply voltage required to run the ATMEGA328P used in Arduino boards as microcontroller.

How to Code Arduino – Beginners Guide
Arduino is an open-source platform quite useful for people who are into embedded systems. Arduinoâs main components include Arduino board inside which we have microcontroller and the other main part is Arduino IDE (Integrated Development Environment) also known as Arduino Software where we can write the code and IDE compile that code into binary Hex file which can be read by the microcontroller.
Arduino IDE is a cross platform software available on Windows, Mac and Linux. Arduino language which is derivative of C++ is used to program Arduino boards using the IDE.

What is TX and RX on Arduino
Arduino uses serial communication to transfer data between microcontroller and PC or with any other microcontroller. A serial bus is used for this communication which consists of two terminals one is for sending data other one for receiving data.
