5 modern alternatives to essential Linux command-line tools

Thursday 25th of June 2020 07:03:00 AM

In our daily use of Linux/Unix systems, we use many command-line tools to complete our work and to understand and manage our systems—tools like du to monitor disk utilization and top to show system resources. Some of these tools have existed for a long time. For example, top was first released in 1984, while du's first release dates to 1971.

Over the years, these tools have been modernized and ported to different systems, but, in general, they still follow their original idea, look, and feel.

Take control of your data with associative arrays in Bash

Tuesday 23rd of June 2020 07:01:00 AM

If you've ever written code, whether it's a shell script, a Python script, C++, or even Scratch, then you know that variables are vital. Computers and coders use variables as waystations, where they surreptitiously pass information back and forth. For instance, if you need to process a user's name in a shell script, you might set up a variable, put the username into the variable, and then instruct the computer to do something to the variable (check it against a list of authorized users, for example).

Customize your Linux terminal with your favorite logo

Tuesday 23rd of June 2020 07:00:00 AM

I enjoyed using my terminal's green-on-black color scheme for many years. It is reminiscent of the DEC VT100/220 terminals that I used in college. I began to get bored with it earlier this year when I bought a tenkeyless keyboard from Hyper-X. The keyboard is black, and the keys are backlit in red, so I changed my terminal's colors to match. I think it looks really cool at night.

Productivity is a subjective term, but essentially, it's a measurement of how efficiently a particular task is completed. Everyone has different things that keep them productive—some people need help staying on task, some people need a particular kind of work environment, some people need alerts and reminders to avoid missed deadlines, and some need assistance with repetitive, manual chores.

How to prepare to write your first Mycroft AI skill using Python

Friday 19th of June 2020 07:02:00 AM

With the recent worldwide pandemic and stay-at-home orders, I have been looking for things to do to replace some of my usual activities. I started to update my home electronics setup and, as part of that, to delve into home automation. Some of my friends use Amazon's Alexa to turn lights on and off in their house, and that is appealing on some level. However, I am a privacy-conscious individual, and I was never really comfortable with devices from Google or Amazon listening to my family all the time (I'll ignore cellphones for the sake of this conversation).

How to sell open source software

Friday 19th of June 2020 07:00:00 AM

In 2010-2011, Mike Jumper started the Guacamole project, a multi-protocol gateway that allowed admins to securely serve up desktops remotely. The client interface ran in the browser, so it was a lightweight, easy-to-use replacement for some older remote access solutions. The project immediately started to grow, resulting in a number of incoming requests for support and help.

7 signs of a great open source project manager

Thursday 18th of June 2020 07:01:00 AM

Project managers go by various names—for example, scrum master, delivery manager, and project coordinator—and have various styles. Yet they all have the same root objectives: to coordinate their team's work as well as that of external and internal teams and to remove any blockers that could hinder a project's implementation. Each project manager has a unique management style, but there are some universal traits that make a great project manager stand out.

Play with virtual LEGOs using open source tools

Thursday 18th of June 2020 07:00:00 AM

My childhood consisted of about 20% Dungeons & Dragons (D&D) and 80% LEGOs, with a pretty strong crossover of the two. I wasn't allowed to actually play D&D for a variety of reasons, but through some mental acrobatics worthy of a level 15 rogue, I determined that building AD&D characters didn't count as playing, and recreating Dragonlance in LEGO form was a pretty good approximation of the game.

4 essential tools to set up your Python environment for success

Wednesday 17th of June 2020 07:02:00 AM

Python is a wonderful general-purpose programming language, often taught as a first programming language. Twenty years in, multiple books written, and it remains my language of choice. While the language is often said to be straight-forward, configuring Python for development has not been described as such (as documented by xkcd).

Will LibreOffice 7.0 be only Personal Edition for individual use???

Look at LibreOffice logo with "Personal Edition" phrase, look at sidebar in Start Center with the same phrase and note to "The Personal edition is supported by volunteers and intended for individual use." And what is mean? Where is any public announcement? They say it was in marketing mail list. How many people read that mail list? Five? It means that I can't install LibreOffice 7.0 in any organization in Russia, because our controlling people will be see very simple to legality in this case: open the About dialog -> read that "intended for individual use" and LibreOffice logo with "Personal Edition" -> you can't use LibreOffice here! Nobody will check what say MPL 2.0 license about it or why TDF made it, they just point a finger at it and they will be right! It will close for LibreOffice any education organizations like schools or colleges or universities. I wont popularize LibreOffice for young people because they will never see LibreOffice in them schools. I against these changes. Please revoke it! Read more

Security 101: Beginning with Kali Linux

I’ve found a lot of people who are new to security, particularly those with an interest in penetration testing or red teaming, install Kali Linux™1 as one of their first forays into the “hacking” world. In general, there’s absolutely nothing wrong with that. Unfortunately, I also see many who end up stuck on this journey: either stuck in the setup/installation phase, or just not knowing what to do once they get into Kali. This isn’t going to be a tutorial about how to use the tools within Kali (though I hope to get to some of them eventually), but it will be a tour of the operating system’s basic options and functionality, and hopefully will help those new to the distribution get more oriented.
