How to connect to PostgreSQL database using pgAdmin 4?

 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 ...

Group mining-Групповой майнинг


Cryptocurrency mining in a pool is an excellent answer to the question of how to start mining on a home computer without buying or building a powerful farm (or at least a rig). Miners will unite in groups, and the reward for the found block is divided among all participants. Therefore, even the owner of not very productive equipment can count on a small share.

For mining in the pool, you can use a PC with a modern video card, the amount of video memory of which is at least 4-6 GB GDDR5, even better - 8 GB or more. If the equipment is assembled independently and specifically for cryptocurrency mining, you can buy a motherboard with support for 6, 8 or even 12 graphics cards - for example, ASUS Prime H270-PLUS.

To connect video cards, you will need risers, and for the device to work, you will have to buy an SSD drive of at least 120-160 GB and a modern, but not necessarily productive processor. All this is collected in a separate building.

The mining algorithm in the pool is as follows:

Open a cryptocurrency wallet on a crypto exchange such as Binance or Bittrex.
Choose the right pool. You should be guided by ping (at least 100 ms), total hashrate (the more, the better) and the minimum payout threshold.
Download the mining program, choosing it according to the type of coin and the brand of the video card. For Ethereum and an Nvidia card, the GMiner utility is suitable.
Put the equipment into operation and start mining.
Additional settings will help to increase the efficiency of the assembled rig or a computer with a powerful video card. To do this, you can use the MSI Afterburner utility or similar softw
