LunarVim

LunarVim is a fast IDE layer for Neovim. Vim, at some point let you be focus on the code, and by that, use the keyboard as the main tool, instead of the mouse.

Here's the list of steps to install LunarVim (and NeoVim) in Ubuntu.

$ sudo apt install software-properties-common -y

$ sudo add-apt-repository ppa:neovim-ppa/stable -y

$ sudo apt update

$ sudo apt install neovim -y

$ bash <(curl -s https://raw.githubusercontent.com/lunarvim/lunarvim/master/utils/installer/install.sh) 

Add lvim to $PATH

If your terminal can't find the lvim command, add the installation folder to your path or move the lvim command to somewhere in your path. The default install folder is ~/.local/bin.

Patch_Tuesday Utils

A step-by-step how I generate patch_tuesday.exe from python script. You can download the python script or the executable directly (at GitHub).

c:\home> pip install colorama

c:\home> pip install pyfiglet

c:\home> pip install pyinstaller

 

Method 1:

c:\home> pyinstaller --onefile --add-data "C:\Python3\Lib\site-packages\pyfiglet";./pyfiglet   patch_tuesday.py

Method 2:

c:\home> pyinstaller --onefile --collect-all pyfiglet patch_tuesday.py

c:\home> cd dist

c:\home\dist> patch_tuesday.exe -h

patch_tuesday.exe -h

c:\home\dist> patch_tuesday.exe -k 2022-jun -v

patch_tuesday.exe -k 2022-jun -v

Tips: Try "patch_tuesday.exe -k 2022-jun -vc" for chart output.

CodExt – Python Codecs extension

CodExt is a (Python2-3 compatible) library that extends the native codecs library (namely for adding new custom encodings and character mappings), hence its name combining CODecs EXTension. It provides 120+ new codecs and also features a guessing mode for decoding multiple layers of encoding and CLI tools for convenience.

Linux System Monitoring Tools

One thing I like Linux is about "command line", and the other is the terminal-based system monitoring tools.

Other the the standard "top" utility that helps to display al the running processes and gives some important information on the performance of the system.

Here are a list of "top" alternatives.

2. atop - https://www.atoptool.nl/index.php
   
3. nmon - http://nmon.sourceforge.net/pmwiki.php?n=Main.HomePage

Mouse Jiggler

With the idea from HakByte, we wrote a similar small python utils and convert it o Windows EXE. 

This is mouse jiggler tool which prevents it from falling asleep by moving the mouse to simulate human input (bypass screensaver locking).

Then I just convert it to Windows executable with pyinstaller.

pyinstaller --onefile --noconsole mouse_jiggler.py

pyinstaller --onefile -w -f  mouse_jiggler.py
