Git Essentials Crash Course - Introduction This is not Java but several newbie developers ask the same question, how to use GIT and how does GIT works so here it goes...
Bayes Theorem provides a principled way for calculating a conditional probability. It is a deceptively simple calculation, although it can be used to easily calculate the conditional probability of events where intuition often fails. Bayes Theorem also provides a way for thinking about the evaluation and selection of different models for a given dataset in …
Finally, after many people have asked for it: here is part two of the mutt-series: this time we talk about actually using and configuring mutt, and some other smaller tools needed for a nice email-workflow.
The link to part one is reported in the beginning of the article.
In order to use a GnuPG key on a smartcard or Yubikey, a GnuPG key needs to be created. This post will show you how to create a GnuPG key with sub-keys for signing, encryption and authentication. The authentication key can be used later on to authenticate via ssh as well.
peco is a CLI utility that filters text interactively. The tool is written in the Go programming language. It's free and open source software.
Say you have an external hard drive with layers upon layers of cryptically named folders and intricate mazes of directories (like here, or here). How can you make sense of this mess? Python offers various tools in the Python standard library to deal with your file system and the folderstats module can be of additional help to gain insights into your file system.
In this article, you will learn the various ways to traverse and explore the file system with Python. In the next section, you will see how to extract statistics from files and directories. In the last section, you will see a practical way to analyze folder structures with folderstats and Pandas with some use cases and visualizations along the way.
Learn what Amazon Web Services (AWS) Lambda is, and why it might be a good idea to use for your next project.
In order to show how useful Lambda can be, it’ll walk through creating a simple Lambda function using the Python programming language. It’ll test it out, as well as take a look at what Lambda provides for metrics and logging.
Awk is a very nice language with a very strange name. In this first article of a three-part series, Daniel Robbins will quickly get your awk programming skills up to speed. As the series progresses, more advanced topics will be covered, culminating with an advanced real-world awk application demo.
This article will give a brief introduction to SSMTP and steps to install it and use the same to send emails from Linux terminal.
Moving your filesystem to USB is a great way to improve reliability, speed and storage space on your Raspberry Pi. If you’re running something that is writing a lot of data constantly then having your filesystem on USB is safer because it’s less likely to get corrupted or stop working with a high amount of write cycles.
This tutorial is using a USB stick which doesn’t require any additional external power, if you want to use a larger USB hdd you will have to also get a powered USB hub because you’re Raspberry Pi doesn’t have enough juice to power it.
I’m using Raspbian for my operating system and I’ll assume you know how to install and configure that yourself.

Which built-ins should you know about?
I estimate most Python developers will only ever need about 30 built-in functions, but which 30 depends on what you’re actually doing with Python.
We’re going to take a look at all 69 of Python’s built-in functions, in a birds eye view sort of way.

The Linux fd command is an quick and efficient way to find files in the terminal. Like the find command, it comes in handy often, however, the find command can be a bit tricky for those new to Linux and especially it's command line. This guide will help you get up to speed with this very useful command line tool.
The xargs utility allows you to build and execute commands from standard input. Xargs is usually used in combination with other commands through piping. In this tutorial, we'll cover the basics of using the xargs command.
In order to successfully work with the Linux sed editor and the awk command in your shell scripts, you have to understand regular expressions or in short regex. Since there are many engines for regex, we will use the shell regex and see the bash power in working with regex.
First, we need to understand what regex is, then we will see how to use it.
Table of contents include:
What is regex, Types of regex, Define BRE Patterns, Special Characters, Anchor Characters, The dot Character, Character Classes, Negating Character Classes, Using Ranges, Special Character Classes, The Asterisk, Extended Regular Expressions, The question mark, The Plus Sign, Curly Braces, Pipe Symbol, Grouping Expressions, Practical examples, Counting Directory Files, Validating E-mail Address.
The author tried to edit data in spreadsheet programs.
This post illustrate ho to use Vim to edit tabular data, although there are a few things that will make it more pleasant. It is assumed that editing files are in tab-separated value format (TSV).
"But what about CSV files?" Just. Don't.
Do: convert your CSV to TSV and back for editing.

This is a tutorial on building your own shell using Rust, in the spirit of the build-your-own-x list. Creating a shell is a great way to understand how the shell, terminal emulator, and OS work together.
