Linux distributions in Day-to-Day Life

There are a few terms that may confuse Linux beginners. The first thing is its name, Linux vs GNU/Linux, the term Linux refers to the Linux kernel only. In reality many users refer to Linux as the operating system as a whole, the kernel plus libraries and tools. Also the term Linux is used to include all the programs that run on Linux, or that are available for this great operating system.
Furthermore, the description GNU/Linux needs understanding. Linux distributions with this name prefix are fleshed out with GNU implementations of the system tools and programs. One such example is Debian GNU/Linux. The GNU project goes back to the initiative of Richard M. Stallman and his dream to develop a free UNIX system. Based on his experiences at MIT and the collaboration with other colleagues he choose to use free software that was already available to rewrite the tools he needed. This included the TeX typesetting system as well as X11 window system. He published the rewritten tools under the GPL license whenever possible to make his work available freely to everyone who was interested in it.

A Linux distribution is a collection of software packages that fit together. A distribution is maintained by a team of software developers. Each member of the team focuses on a different package of the distribution. Together as a team they ensure that the single software packages are up-to-date and do not conflict with the other packages of the same release of the distribution.
As of 2019 for Debian GNU/Linux 10, the distribution includes over 13,370 new packages, for a total of over 57,703 packages. A repository is a directory of packages with a certain purpose. Debian GNU/Linux sorts its packages according to the development state. The official repository is named stable and reflects the current release of stable packages. The other repositories are named testing and unstable, and work in the same way but do not count as official packages.
Typically a Linux distribution comprises of packages for a Linux kernel, a boot loader, GNU tools and libraries, a graphical desktop environment with a windows environment, as well as additional software like a web browser, an email client, databases and documentation. The software is provided in two ways; as the source code and as the compiled binary packages. This allows you to understand how the software is designed, to study it and to adjust it according to your personal needs.

Depending on the focus of the Linux distribution, it also contains packages for a specific purpose like network or forensic tools, scientific software for educational purposes, and multimedia applications.

How to make Firefox an essential tool for OSINT

Before start reading this blog post, and gain serious interests in extra privacy tweaks on Firefox. Many related addon’s & tweaks in this post are already mentioned in my older post about tweaks that will enhance your privacy on internet with Firefox.

Okey! What is OSINT? Right?!

OSINT is defined by wikipedia as:

“Open-source intelligence (OSINT) is intelligence collected from publicly available sources. In the intelligence community (IC), the term “open” refers to overt, publicly available sources (as opposed to covert or clandestine sources); it is not related to open-source software or public intelligence.” (source)

So let’s summon this as simple as possible, basically anything you can find on the internet. The key point for me about OSINT is that it only relates to information you can find for free. Having to pay to get access to information such as an API or raw data isn’t really OSINT material. I’m not saying that’s wrong or should be a reason not to use data from paid sources, it’s just not really OSINT in its trust form. Clear?! Let’s carry on!

The most vital application for the search methods that must be conducted  is within a web browser. Most Windows users settle for Internet Explorer or Edge, well. I do not recommend using those browsers for OSINT analysis. The Firefox browser has enhanced security and a feature called “add-ons” or “extensions”. These are small applications that work within the browser that perform a specific function. They will make searching and documentation much easier. I also use, and encourage others to use, the Chrome web browser when necessary. However, many of the extensions that I need are only compatible with Firefox. The following instructions apply to any versions of Firefox, including Windows, Mac, and Linux.

Refreshing the /boot

Every three months once kernel team releasing new stable kernel which comes with new features, Improved Hardware & System Performance. At least monthly once we will get kernel patch/update from operating system for varies fix. For best practices, i would advice users to install all the updates regularly to make the system up and running without any issue.

And /boot partition sometimes needs a bit of that attention. If you enable automatic
updates, it will fill up with old kernels that you’ll probably never need. It also will stop
you from running dnf (Dandified Packaging Tool) to install or remove anything. If you find yourself in this
situation, you can use rpm to get around it. RPM is the higher-level package manager
in Red-Hat-based distributions, and it’s very useful when dnf has “broken”.
