Abandon Windows in favor of Linux operating system – Tips&Tricks – Part 1

Lately, I've been moving around a bit more and working with more computers. As it happens, the manufacturer announced that it was discontinuing support for Windows 10, and the next release seems like a bad joke from a privacy perspective. That's why I decided to abandon Windows 10 in favor of the Linux operating system on my desktop machines. I thought it would be a cool topic to show that it can be done and to sell a few solutions to the problems I encountered. Enjoy the material!

Comparison of rar, bzip2, lbzip2 compression

Recently, I've been busy preparing various directories for additional archiving in Linux (it's about files from the /var/log/ location) containing archives of reports of performed operations in the system and running programs (services such as www etc.). Since I often use archiving to RAR format, I decided to see if it would work in this case as well.

New script – Nextcloud installer for Linux (no docker)

I wrote a script that installs Nextcloud package (an alternative to other disk services in the so-called cloud like One Drive or Google Disk), in Linux (Debian and Enterprise Linux distros). To work it requires only a clean system, everything will install and configure itself (so that it works on the local network, or outside with few more steps from user).

Here is the link: Nextcloud Installer

Today I had the opportunity to update the firmware of the Mellanox ConnectX-3 card, and I thought I'd give a closer look at the process (it should work for previous ConnectX series card models as well).

The script installs and pre-configures things like web server, database server, PHP interpreter.

UNMS / UISP on EL8 Linux

I published a script that executes the installation of UNMS (Ubiquiti Network Management System) on CentOS 8 Linux / RHEL 8, despite the lack of support for those distribution by the manufacturer.

Installation manual and download link can be found in projects – "UNMS / UISP for CentOS 8 Linux installation script".

Script for CentOS 8 Linux from KODI to HTPC

I prepared a script that automates the installation and configuration of CentOS 8 Linux with KODI (formerly XBMC) under HTPC (a computer for media playback). Thanks to this, we get a ready system which, after connecting to e.g. TV or projector, enables comfortable playback of multimedia materials (video, audio, streams).

File, commands to download it, and even video material on YouTube can be found on the newly created subpage of this project. You are welcome: HTPC on CentOS 8 Linux with Kodi.

Testing Deepin 20 graphical interface manager on Fedora 32

There have been packages of a drop-down version of the window manager, Deepin Desktop 20 (known for its Debian-based Deepin Linux distribution). To check how the builder version looks and works on Fedora Linux 32 just use the terminal and the following commands:

Adding reporsitory of Deepin testing Desktop for Fedory:
# sudo dnf copr enable cheeselee/deepin-20-testing

Anad next we install packages:
# sudo dnf install deepin-api deepin-album deepin-calculator deepin-calendar deepin-control-center deepin-daemon deepin-desktop-base deepin-desktop-schemas deepin-dock deepin-draw deepin-editor deepin-file-manager deepin-icon-theme deepin-image-viewer deepin-kwin deepin-launcher deepin-menu deepin-network-utils deepin-picker deepin-polkit-agent deepin-qt-dbus-factory deepin-qt5integration deepin-qt5platform-plugins deepin-reader deepin-screensaver

Re-login but select Deepin on the login screen (cog down on the right). That's all.

BBClone statistics inside WordPress

Today's entry concerns the launch of statistics of website visits based on the WordPress system, using the BBClone – a script entitled as – A PHP based Web Counter on Steroids!

An example of how the BBClone works can be seen here: https://www.bbclone.de/demo/.

There's not much to describe, so I'll get to the point.
I assume you already have a working WordPress engine site.

1 – We are downloading a development version of the BBClone (the last stable release is from 2015, and does not support PHP version 7, so we need a version with later changes). Link to file: http://download.bbclone.org/bbclone-nightly-build.zip.
2 – The unpacked files are copied via FTP to a server. We can rename the bbclone directory to another.
3 – Edit the config.php file from the /conf/ directory, where you set the parameters as required.
4 – We change the WordPress file, template-loader.php, which is located in the /wp-includes/ directory. Simply add this piece of code under the first line containing "<?php":

define("_BBC_PAGE_NAME", get_bloginfo("name") . wp_title("/", false));
define("_BBCLONE_DIR", "/home/user/public_html/bbclone/");
define("COUNTER", _BBCLONE_DIR."mark_page.php");
if (is_readable(COUNTER)) include_once(COUNTER);

Instead of /home/user/public_html/bbbclone/ (bold above) you should enter your own full bbclone directory location on the server. Upload the modified file, replacing the original and it's ready.

The only thing you need to remember is to correct this file after updating WordPress.
