The 7-Zip archiver does an excellent job of compressing data efficiently. It can be called a "Swiss knife" in the world of archivers. It supports various compression algorithms and a wide variety of data formats such as ZIP, gzip, tar and RAR. A separate plus is that the archiver is free.

The first version of 7-Zip was released on July 18, 1999; in a relatively short time, the archiver could become very popular. A relative disadvantage of 7-Zip is that there is only a version for Windows (official client). But now, after only 22 years, there is also a version for Linux, an official build from the developers.

Kali 2019.4 Version

Its really great news to hear that the fourth and final release of 2019 i.e; Kali 2019.4, is available in the market to download immediately. Kali 2019.4 includes many of the exiting features and new updates, let us discuss those updates.
• It contains a new default desktop environment.
• It consists of the New GTK3 theme.
• It also introduced a new feature named “Kali Undercover” mode.
• A new home for Kali Documentation and is Git powered now.
• It also has a feature of public packaging which means getting our tools into Kali.
• The next feature is Kali NetHunter Kex which means that Full Kali Desktop on Android.
• It also has a feature of BTRFS during setup.
• It also has the feature of Added PowerShell.
• Its kernel is upgraded to version 5.3.9.
• It also has the feature of normal bugs fixes and updates.
Now, let us discuss some of the features in detail.

Kali Undercover

As we all know that the environment changes day by day, so they thought they would take a side step and do something for fun to all people. A person named Robert, who leads the penetration testing team of development of Kali, he is suggested about the Kali theme that looks like Windows as a casual view, they have created the Kali Undercover theme.
Let us assume that we are work in a public place, hacking away, and we might not want the distinctive Kali Dragon for everyone to see and wonder what if it is we who are doing. So, they made a little script that will change our Kali theme to look like a default Windows installation. That's the way by which we can work a bit more incognito. If after we are done and in a more private place, run that script again and we will switch back to our Kali theme. It's like a magic for us.

Public Packaging

In Kali one of the new feature included is documenting how you can make a new package. One of the most common problems is bug reports is requests for us to add some of the new tools or update existing ones. After some time, the tool developers recognized themselves that having their tool in the Kali repo is the easiest distribution channel for the purpose of security assessment tools is there. It is always been difficult that the volume of this to keep up with, and we have to make some hard decisions on where to commit our limited resources. Now, with this work-flow in place and documented, we do not have to wait on them. The simple thing is that to Go ahead and package up our tool and submit it off to them for approval. This is like an awesome way to get involved with improving Kali.

BTRFS during setup

Another significant new feature or a new addition to the documentation is the use of BTRFS as our root file system. This is an amazing approach documented by Re4son, that when done gives us the ability to do file system rollbacks after upgrades or updates. Let us assume that we are in a VM and about to try something that is new, then we will often take a snapshot in case if things go wrong then we can easily go back to a known-good state. However, when we run Kali bare metal that is not so easy. So the option is that we have to end up being extra careful, or if things go wrong then we have a lot of manual clean up to do. With BTRFS, we have this same snapshot capability on a bare metal install. As we know that this is new, it is not integrated into our installer yet. Once we get some feedback on how it is working for everyone, the next step is to streamline this and make it an easier option in our installer. So if we try it out, be sure to let them know how it works for us.


On move to some other features, in case if we missed it PowerShell is now in Kali. This has been really great to bring the ability to execute PowerShell scripts directly on Kali.

In this article, I'll talk about some of the ideas on which high-level parts of Android are built, about several of its predecessors and about the basic mechanisms of security.

I'm used to looking for problems in code or in the system, using logs or monitoring indicators, which are displayed on pretty control panels with a simple and intuitive interface. However, if for some reason the data does not arrive to the control panel, or the logs of some service are unavailable, debugging becomes more complicated. Now there are few such problems, they are rare, but they do happen. Therefore, in our time is very valuable knowledge of tools that help to understand what is wrong with a certain process on any computer.

In this series of articles, I'll talk about the internal Android device - about the boot process, about the contents of the file system, about Binder and Android Runtime, about what they consist of, how the applications are installed, running, interacting with each other, about the Android Framework, and on how Android provides security.

The development team working on PVS-Studio has finally started developing its product for Linux. That was the news that the CTO Andrey Karpov wrote about in the article. Long disputes and requests of the readers on, discussions on Reddit, and other places can now gain a new round of comments. As it is mentioned in the article, you can volunteer to help the developers to test this product and improve it to a better level.

There are many tasks on the way of PVS-Studio to Linux, that the technical director is talking about. Put briefly, these are:

- more complete support of GCC and Clang;
- a new system of regression tests in Linux, so that you can track the changes results in the analyzer kernel and add new diagnostics;
- compiler monitoring to help programmers quickly and easily check the project without distracting people who support makefiles and the build system in general;
- documentation improvement, so that the user can get information with the examples about any diagnostic;
- testing, distribution, support organization.

In this article you will find more details about the abilities of PVS-Studio for Windows and the tasks it can already solve on Linux.

I do not know why I may need it, but suddenly I wanted to have two mouse pointers in Linux, after all I already have two mice, one is a wireless mouse and the other is a touchpad one. The idea came at a time when I hooked up a second mouse, namely, a third cursor control device.

I want each mouse to get a cursor, but how do I get it?

Let's see what xinput will tell us:

max 23:20:19 ~ $ xinput list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ Logitech USB Receiver id=10 [slave pointer (2)]
⎜ ↳ Logitech USB Receiver id=11 [slave pointer (2)]
⎜ ↳ Genius 2.4G Wireless Mouse id=12 [slave pointer (2)]
⎜ ↳ SynPS/2 Synaptics TouchPad id=14 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ Power Button id=6 [slave keyboard (3)]
↳ Video Bus id=7 [slave keyboard (3)]
↳ Sleep Button id=8 [slave keyboard (3)]
↳ Villem id=9 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=13 [slave keyboard (3)]
↳ HP WMI hotkeys id=15 [slave keyboard (3)]

Finally, Linux has shown growth of the rates that are expected for a long time. The market share of Linux increased by 64% on the desktop OS since May to December 2011, according to a global monitoring service Net Market Share, which collects statistics about visitors from over 40,000 websites. The unique audience makes about 160 million people per month, therefore, the measurement error is very small.

Linux origin can be traced back to the 70s of the 20th century. Its starting point began from the first release of Unix operating system in 1969 by Bell Laboratories, subsidiary of AT & T in the U.S. Unix has become the basic one for a large number of industrial-grade operating systems. The most basic of them showed on this timescale:

Linux is mostly indebted to two projects - GNU and Minix.


imageThe story of the GNU project started in September 1983. The founder of GNU project, Richard M. Stallman worked at that time in the Artificial Intelligence Laboratory at Massachusetts Institute of Technology, Cambridge, Massachusetts. Stallman is considered as one of the most leading programmers of these days.
