 How to connect to PostgreSQL database using pgAdmin 4? In order to set up a connection to the PostgreSQL database, run pgAdmin 4, for example, from the Start menu. As a result, pgAdmin 4 will start. Then click the menu "Object->Create->Server" or right-click on the item "Servers" and select "Create->Server". The server connection settings window will open. On the General tab, we invent and enter the name of our server in the Name field. On the Connection tab, enter the server IP address, username, password, and if you want, you can check the “Save password?” to save the password and not to enter it every time you connect. If the standard port (5432) of the PostgreSQL server has been changed, then you also need to change it here. Press the "Save" button. Note! The PostgreSQL server must be installed, configured and running. We considered an example of installing and configuring PostgreSQL DBMS on Linux Debian in the material “Installing ...

Ventoy

 


one of the simplest, but at the same time quite functional program that allows you to create not just bootable flash drives, but also multi-boot ones, we are talking about the Ventoy program.


Ventoy


Ventoy is a free and open source bootable flash drive software.

Most programs that allow you to create bootable flash drives, including those that will be discussed below, imply certain actions with the ISO image, i.e. they write it in a certain way to a USB flash drive.


However, the Ventoy program works a little differently, and this is its main feature: in order to create a bootable USB flash drive with Linux, we just need to install the program on a USB flash drive and copy the ISO image to this flash drive in the usual way. At the same time, we can copy not only one image, but several, and not only ISO files of Linux distributions, but also other ISO images of boot systems.




Moreover, this flash drive, after it becomes bootable, you can continue to use, i.e. store regular files on it.


However, of course, this program also has its drawbacks, for example, the fact that some ISO files may have problems, i.e. not all ISO files will boot, but most ISO files, including Linux distributions, are of course supported.
