7-zip File Free File Compression Utility

7-Zip is a free and open source file archiving utility; a utility used to place groups of files in compressed containers called “files”. It is developed by Igor Pavlov and was published in 1999. 7-Zip uses its 7z file format but can read and write several other file formats. The program can be used from a command line interface such as the p7zip command, or through a graphical user interface that also has shell integration. Most of the 7-Zip source code is under the GNU LGPL license; However, the unRAR code is under GNU LGPL with a “unRAR restriction”, which states that developers can not use the code to reverse the RAR compression algorithm.

An open source alternative to WinZip and WinRAR is 7-Zip. 7z is a file archiver with a high compression ratio that can be used in Windows computers without limiting the number of computers.

Formats

By default, 7-Zip creates files in 7z format with a .7z file extension. Each file can contain multiple directories and files. As a container format, security or downsizing is achieved by using a combination of stacked filters. These can consist of preprocessors, compression algorithms and encryption filters.

Compression of the 7z kernel uses a variety of algorithms, the most common being bzip2, PPMd, LZMA2, and LZMA. Developed by Pavlov, LZMA is a relatively new system, which debuts as part of the 7z format. LZMA uses a sliding dictionary based on LZ up to 4 GB in size, supported by a range encoder.

The native 7z file format is open and modular. Filenames are stored as Unicode.

The 7z file format specification is distributed with the source code of the program, in the “doc” subdirectory.

Features:

  • AES 256-bit encryption. Encryption can be enabled for files and 7-zip hierarchy. When the hierarchy is encrypted, users must provide a password to see the file names contained in the file. Zip file developed by WinZip The AES encryption standard is also available in 7-Zip to encrypt ZIP files with 256-bit AES but does not offer file name encryption as in 7z files.

  • Dynamically variable sizes, which allow the use of backup copies on removable media, such as writable CDs and DVDs

  • Ease of use as a basic orthodox file manager when used in dual panel mode

  • Multi-core CPU thread

  • Open EXE files as files, allowing the decompression of data from many “Configuration” or “Installer” or “Extract” programs without having to execute them

  • Unzip files with names of damaged files, rename files as needed

  • Create self-extracting mono evolutionary files

  • Command line interface.

  • Graphical user interface. The Windows version comes with its graphical interface; however, 7zip uses the Unix / Linux file manager GUI.

  • 7-zip does not control the order of the files in the files.It ignores the order of the file names on the command line. Therefore, 7-zip cannot be used in cases where the order of file names is important. For example, the EPUB format, which is based on Zip and HTML formats, requires a certain order of files in the files: a file called “MIME type” must be the first file in the ZIP file.

Benefits of using 7-zip:

  • Open source, without the need to pay to use

  • Graphical interface for the Windows platform

  • You can compress/unzip the following types of files: 7z, ZIP, GZIP, BZIP2 and TAR

  • Integration with Windows Shell

  • Powerful file manager

  • Powerful command line version

  • There is a command line version port for Linux / Unix

The use of 7-zip by a large number of users over the years has shown that 7-zip has been efficient and reliable for file management.

Blender Free Graphics And Animation Studio

Blender is a set of free, open source, professional 3D graphics software that is used to create animated movies, visual effects, art, 3D printed models, interactive 3D applications and video games.

In January 1995, the Dutch animation studio Neo Geo developed Blender as an internal application with software developer Ton Roosendaal as lead author. The name of Blender was inspired by a song of Yello, from the album Baby.

When another company acquired neo Geo, Not a Number Technologies (NaN) in June 1998 was founded by Ton Roosendaal and Frank van Beek to develop Blender further, formerly distributing it as shareware until the bankruptcy of NaN in 2002.

On July 18, 2002, Roosendaal launched the “Free Blender” campaign, a precursor of crowdfunding. The campaign was aimed at obtaining the Blender open source software for a one-time payment of 100,000 € (100,670 US $ at the time) collected from the community. On September 7, 2002, it was announced that they had raised enough funds and would be launching Blender’s source code. Today, Blender is a free and open source software that, apart from the two full-time and two part-time employees of the Blender Institute, has been developed by the community.

Initially, Blender Foundation reserved the right to use dual licenses, so in addition to GPLv2, Blender would also be available under the Blender license that did not require disclosure of source code but required payments to the Blender Foundation. However, they on no occasion exercised this option and suspended it indefinitely in 2005. Blender is only available under “GNU GPLv2 or later” and has not been updated to GPLv3 because ” no obvious benefit was observed. ”

Blender’s Outstanding features

  • 3D modelling

  • UV unpacking

  • texturing

  • raster graphics editing

The stages of the medico-legal reconstruction of a mummy made by Blender by the Brazilian 3D designer Cícero Moraes.

The official versions of Blender for Windows, MacOS and Linux, and a port for FreeBSD are available in 32 bits and 64 bits. Often distributed without detailed examples of scenes found in other programs, the software contains features that are characteristic of high-end 3D software. Among this abilities are:

  • It supports several geometric primitives, including polygon mesh, fast surface modelling subdivision, Bézier curves, NURBS surfaces, METABALLS, icospheres, multi-res digital sculpture (dynamic topology mapping, binding, resynchronization), decimation), contour font, and a new n-gon modelling system called B-mesh.

  • Internal rendering engine with scan representation, indirect lighting and environmental occlusion that can be exported in a wide variety of formats.

  • A Pathtracer rendering engine called Cycles, which can take advantage of the GPU to render. Cycles support Open Shading Language from Blender 2.65.

  • Integration with a series of external rendering engines through add-ons.

  • Keyframe animation tools that include inverse kinematics, skeleton, hook, curvature and lattice-based deformations, shape animations, non-linear animation, constraints and vertex weights.

  • Simulation tools for soft body dynamics, comprising mesh collision detection, fluid dynamics, LBM, smoke simulation, rigid body dynamics, Bullet, ocean generator with waves.

  • A particle system that includes hair support centred on particles.

  • Modifiers to apply non-destructive effects.

  • Python script for creation of tools and creation of prototypes, logic of games, import/export from other formats, automation of tasks and customized tools.

  • Non-linear video / audio basic edition.

  • The Blender game engine, a subproject, offers interactivity features such as collision detection, dynamic engine and programmable logic. It also allows the creation of independent applications in real time ranging from architectural visualization to video games.

  • A fully integrated node integrator in the accelerated rendering pipeline with OpenCL.

  • Procedural textures and knots, texture painting, projective painting, vertex painting, painting of weights and dynamic painting.

  • Real-time control during physical simulation and rendering.

  • Camera and object tracking.

With these excellent features created by Blender, over the years the globe has rated Blender as one of the most efficient and reliable software.

Open Office the Free Office Suite for your computer

OpenOffice.org (OOo), generally known as OpenOffice, is an open-source office suite. It was an open-sourced version of the earlier StarOffice, which Sun Microsystems acquired in 1999, for internal use.

OpenOffice comprises a word processor (Writer), a spreadsheet (Calc), a drawing application (Draw), a presentation application (Impress), a formula editor (Math) and a database administration application (BASIC). Its default file format was the OpenDocument (ODF) format, an ISO / IEC standard, which was created with OpenOffice.org.

Sun opened OpenOffice in July 2000 as a competitor to Microsoft Office, publishing version 1.0 on May 1, 2002.

In 2011, Oracle Corporation, the owner of Sun, announced that it would no longer offer a commercial version of the suite and quickly donated the project to the Apache Foundation.

Apache renamed the Apache OpenOffice software. Other on the go successor projects include LibreOffice (the most developed and NeoOffice (commercial, only for macOS).

OpenOffice.org was developed primarily for Linux, Microsoft Windows and Solaris, and later for OS X, with ports to other operating systems. It has been distributed under the reduced Lesser General Public License GNU version 3 (LGPL); the first versions were also available under the license of Sun Industry Standards Source License (SISSL).

OpenOffice.org was created under the name of StarOffice, an office suite developed by the German company StarDivision of 1985. StarDivision was acquired in August 1999 by Sun Microsystems for US $ 59.5 million because it was cheaper than licensing Microsoft Office for 42,000 employees.

On July 19, 2000, at OSCON, Sun Microsystems announced that it would implement the StarOffice source code download with the intention of building an open source development community around the software and providing a free alternative to Microsoft Office and Open. The new project is called OpenOffice.org, and the code was released as open source on October 13, 2000. The first public version was previewed by Milestone Build 638c, published in October 2001 (which quickly reached 1 million downloads; The final version of OpenOffice.org 1.0 was on May 1, 2002.

OpenOffice.org has become the standard office suite in Linux and has generated many derived versions. It quickly became a significant competition for Microsoft Office, reaching a penetration of 14% in the corporate market in 2004.

The XML file format OpenOffice.org – XML ​​in a ZIP file, easily treatable by a machine – was designed by Sun to become a standard exchange format for office documents, to replace the different binary formats for every usual application. Sun has presented the format of the Organization for the Advancement of Structured Information Standards (OASIS) in 2002 and was adapted to form the OpenDocument standard in 2005, which was ratified as ISO 26300 in 2006. It was created from of version 2 of the native OpenOffice.org format. Many governments and other organisations have adopted OpenDocument, mainly because there was a free implementation readily available.

The development of OpenOffice.org was sponsored primarily by Sun Microsystems, which used the code as the basis for later versions of StarOffice. Developers who wanted to contribute to the code had to sign a contribution agreement that granted joint ownership of any contribution to Sun (and then to Oracle), in support of the StarOffice, business model. This has been controversial for many years. Another public document license (PDL) has also been proposed for documentation that is not intended to be included or incorporated into the project code database.

After the acquisition of Sun in January 2010, Oracle Corporation continued to develop OpenOffice.org and StarOffice, renaming it Oracle Open Office, but with a reduction in the affected developers. Industry observers also pointed to Oracle’s lack of activity in OpenOffice.org or its visible commitment to OpenOffice.org. In September 2010, most of the external developers of OpenOffice.org left the project, due to concerns about the management of Sun and Oracle projects. Oracle’s management of its open source portfolio in general, to form The Document Foundation. TDF launched the LibreOffice fork in January 2011, in which most of the Linux distributions moved quickly. In April 2011, Oracle stopped developing OpenOffice.org and returned the rest of the StarDivision development team. Their reasons for doing so were not disclosed; some speculate that this was due to the loss of spirit shared with much of the community when moving to LibreOffice, while others suggest that it was a commercial decision.

In June 2011, Oracle provided the trademarks to the Apache Software Foundation. It also offered Apache with a code belonging to Oracle for an Apache license, at the suggestion of IBM (for whom Oracle had contractual obligations concerning the code), because IBM did not want the copyleft code with the licence. This code served as the basis for the Apache OpenOffice project.

Features

OpenOffice.org 1.0 was released under the following mission statement:

The mission of OpenOffice.org is to build, as a community, the top international office suite that will run on all key platforms and provide access to all features and data through APIs based on open components and a format XML-based file

Supported operating systems

The latest version, 3.4 Beta 1, was available for versions IA-32 of Windows 2000 Service Pack 2 or later, Solaris and OS X 10.4 or later, Linux (IA-32 and x64), and the SPARC version of Solaris.

The latest versions of OpenOffice.org in other operating systems were:

  • IRIX (MIPS IV): v1.0.3,

  • Mac OS X v10.2: version 1.1.2

  • Mac OS X v10.3: version 2.1

  • Windows 95: version 1.1.5

  • Windows NT 4.0 SP6: version 2.0.1

  • Windows 98 and Windows ME: version 2.4.3

Sources

OpenOffice.org includes OpenSymbol, DejaVu, Liberation fonts (from 2.4) and Gentium fonts (from version 3.2). Versions up to and including 2.3 sources Bitstream Vera. OpenOffice.org also used the default operating system fonts.

Fontwork is a feature that lets users create stylized text with special effects that differ from ordinary text with additional features of gradient color fill, format, font height, and character spacing. WordArt used by Microsoft Word is similar to it. All Fontwork was converted to WordArt When OpenOffice.org saved documents in Microsoft Office file format.

Extensions

Since version 2.0.4, OpenOffice.org supports third-party extensions. In April 2011, the OpenOffice extensions repository listed more than 650 extensions. The Free Software Foundation maintained Another list.

Connectivity

OpenOffice.org can interact with databases (local or remote) using Open Database Connectivity (ODBC), Java Database Connectivity (JDBC) or StarOffice Database Connectivity (SDBC).

Desktop Native Integration

OpenOffice.org 1.0 has been criticized for not having the appearance of applications developed natively for the platforms on which it runs, beginning with version 2.0, the OpenOffice.org toolkit used native widgets, icons, and representation sources in the GNOME, KDE, and Windows libraries.

The problem was particularly obvious in Mac OS X. Previous versions of OpenOffice.org required the installation of X11.app or XDarwin (although the NeoOffice port provides a native interface). Versions since version 3.0 have been run natively with the Apple Aqua GUI.

Security

In 2006, Lieutenant Colonel Eric Filiol of ESAT’s Laboratory of Virology and Cryptology demonstrated security weaknesses, particularly within macros.In 2006, Kaspersky Lab presented a concept virus test, “Stardust”, for OpenOffice.org, this showed that there is no known virus in “nature” but OpenOffice viruses are possible.

In October 2011, Secunia reported that it did not know of uncorrected security deficiencies for the software. A vulnerability was found and corrected in the legacy OpenOffice.org code in LibreOffice in October 2011 and Apache OpenOffice in May 2011.

The above mentioned has described open office from its origin to date.

Top 5 Features Of Antergos Linux That Make It So Compelling

Many people have heard of many versions of Linux but not of Antergos. Due to bad luck, Antergos is underrated but for people who have a passion for exploring new operating systems, they should give it a try.

It is exciting and comes with many of its own thrilling features. Antergos is an Arch based Linux distro.

NOTE: Antergos is not a GUI based Arch but rather an Arch based distro.

The following article will explain some of its bombastic features.

1. Preinstalled Software

When most of operating systems are installed, they are equipped with many preinstalled software. Most of these are not required by general public and they make a system heavy.

Antergos is a baby. It is only supplied with necessary software which produce an outcome of negligible lagging. It comes installed with a video player, text editor, music player and some essential software installed automatically by the OS.

2. Talking About Interface

Antergos is the home to Gnome, Cinnamon, Mate and Openbox. It supports almost all the major interfaces.

After getting a partnership with Numix, one can observe a cascade of beautifully themed icons which provide a serene touch.

3. Stability and Reliability

When most people are asked about their Linux experience? They love everything except complications.

Antergos is known to only come up with extremely necessary software which help make your PC light and steady. You can then build it up according to your own needs.

The coolest thing about Arch distro is that it does not push up new updates the second they are developed. Arch community is known to test the final products again and again before they are set up for global release.

This makes the Antergos customers happy about the reliability of their respective Linux distro.

4. Say YES To Gaming

Ask the developers how difficult is the task of aligning cross platform gaming? For many years, developers have acknowledged a huge gaming potential for Linux users.

Right now, only Ubuntu is officially supported by Steam (speaking in terms of Linux distros) but you can install it on Antergos too. It works smooth with no problems at all.

More than 1000 games of Steam are now accessible on Linux platform.

5. Kudos To Arch Support

Arch support is credited for their amazing response and helpful attitude. Even if you are a noob, the global volunteers help you in any way you desire.

ArchWiki is the most comprehensive Wiki, developed for any Linux distro. Details of every package are portrayed on the magnanimous encyclopedia and if you are stuck, just ask a question.

If Antergos is so much awesome, why is it underrated?

If you are looking for one word answers, the answer is… “complexity”

Arch Linux is complexed. Even professionals find themselves getting challenged by the daunting packages.

But once you get an Arch installation, equipped with GUI, things proceed pretty swell after that moment.

Antergos provides its users a GUI to handle Arch. The ‘Cnchi installer’ is self-explanatory and simple so there’s a 99% chance that you will get to install Antergos without a hassle.

ARCHOS LINUX and how cool it is just to be FREE

Free Operating System Linux

Judd Vinet, a Canadian programmer and occasional guitarist, began developing Arch Linux in early 2001. He released Arch Linux 0.1, on March 11, 2002, as his first official release. He was inspired by the elegant simplicity of Slackware, BSD, PLD Linux and CRUX, and but disappointed by his lack of package management at that time. Vinet has built its distribution on principles similar to those of distributions. He also wrote a package management program called Pacman, to automatically manage the installation, removal and updates of the package.The initial Arch community has grown steadily, as evidenced by a table of forum posts, users, and bug reports. Also, he was known from the start as an open, friendly and helpful community.

The 2005-07-08 ArchWiki has been configured for the first time in the MediaWiki engine.

In late 2007, Judd Vinet dropped his active participation as Arch Developer and transferred the reins to American programmer Aaron Griffin, also known as Phrakture, who remains Arch’s leading developer until now.

Conception and principles of Arch Linux

Arch Linux is known as Linux distribution for computers based on x86-64 architectures. Arch Linux is mainly composed of free and open source software and is compatible with community participation.

The development team’s design approach follows the KISS principle (“keep it simple, stupid”) as a general guide, and emphasizes elegance, correct code, minimalism and simplicity, and expects the user to operate the system. A package manager written exactly for Arch Linux, Pacman, is used to install, remove and update software packages.

Arch Linux uses a progressive release model, so a regular system update is required to obtain the latest Arch software; the installation images published by the Arch team are merely snapshots of the main components of the system.

Arch Linux has complete documentation in the form of a community wiki called ArchWiki. The wiki is widely considered among the Linux community and the ecosystem for often having the most up-to-date information on a specific topic and being applicable beyond Arch Linux.

Arch is mainly based on binary packages. The packages are for x86-64 microprocessors to enhance the performance of modern hardware. A system similar to ports or ebuild is also provided for automatic compilation of sources, known as the Arch Build System.

Arch Linux focuses on design simplicity, which means that the main goal is to create a simple and relatively easy to understand environment directly for the user, instead of providing management point style tools and click on The package manager, for example, does not have an official GUI. This is largely achieved by inspiring the use of clean configuration files, commented succinctly, that are organized for quick access and modification. This earned him a distribution reputation for “intermediate and advanced Linux users who are not afraid of the command line”.

Packet Management

Pacman

Pacman (Arch Packager, an acronym for “package manager”) was developed by Judd Vinet to provide Arch with its package manager capable of tracking dependencies in other to facilitate regular packet changes, It is written in C.

Pacman and package manager manages all packages. Pacman Manages the installation, updates, deletions and degradations of packages, and provides automatic dependency resolution. Arch Linux packages are obtained from the Arch Linux package tree and compiled for the IA-32 or x86-64 architectures. Use binary packages in tar.Xz format, with .pkg placed before that to indicate that it is a Pacman package (giving .pkg.tar.xz).

Installation

The Arch Linux website offers ISO images that can be run from a CD or USB device. After a user formats and partitions their unit, a simple command-line script (pacstrap) is used to install the base system. The installation of extra packages, which are not part of the basic system (e.g., desktop environments), can be done with pacstrap or Pacman after starting (or closing) the new installation.

An alternative way of using CD or USB images for installation is to use the static version of Pacman Package Manager from another Linux-based operating system. The user can mount his newly formatted disk partition and use pacstrap (or Pacman with the appropriate command line switch) to install the base and additional packages with the destination device mount point as the root user. This method is suitable when installing Arch Linux on USB sticks or a temporarily mounted device belonging to another system.

Repositories

Core: it contains all the necessary packages to configure a basic system

Extra: this contains packages not needed for the base system, including desktop environments and programs.

Community: It contains packages created and voted on by the community; it includes packages that have enough votes and have been adopted by a “trusted user”.

Multilibs: a centralized repository for x86_64 users to more easily support 32-bit applications in a 64-bit environment.

Also, there are test repositories that include binary candidates for other repositories. Currently, there are the following test repositories:

Test: it contains packages for core and extra.

Community tests: it contains packages for the community.

Multilib-testing: it contains packages for multilib.

The repositories of transfer and transfer to the community are used for some reconstructions to avoid broken packages during the tests.

Also, there are two other repositories include the latest version of some desktop environments.

Gnome-unstable: it contains packages of a new version of the GNOME software before it is tested.

KDE-unstable: it contains packages of a new version of the KDE software before being released in the tests.

The unstable repository was abandoned in July 2008, and most of the packages were moved to other repositories.

Why Arch Linux?

Most of the principal distributions are split between “stable” (but with ancient packages) and “unstable” (but with avant-garde kindness). If you install LTS (Long Term Support) versions, you will be condemned to only have old packages from a few years ago. If you install unstable repositories, you are doomed to have things explode on your face without explanation and lose hours of navigation through StackOverflow.

Now, it seems that Arch has found the level of trust exactly “right” between stable and avant-garde. Keep pressing the latest version of the software without breaking everything else all the time. So, in Ubuntu 16.04 and Fedora 25, if you want to install Postgresql, you will be stuck in 9.4 or 9.5, but in Arch, you can access 9.6 from Pacman’s main repositories. (By the way, “Pac” kage “Man” ager is the most obvious name of all time).

You can easily Pacman -Sy PostgreSQL, and you are in business.

So, it seems that Arch’s philosophy is to have the most recent version of any software that does not break your system. There is no Big Bang update every six months that breaks everything. Instead, it has a constant update system, where it is still in the most recent version, without having to wait another year for the next big LTS.

Each primary distribution has “non-compatible” repositories for proprietary binaries (for example, codecs) or third-party software. Then there is the Arch User Repository (AUR): a collection of small Git repositories of users that preserve the plain text files of PKGBUILD.

AUR is smart. If you are using MacOS and you’re familiar with Homebrew, you’ll understand, it feels like barrels and formulas. A PKGBUILD can describe a recipe to download available DEB or tar files, disassemble and rebuild as a whole compatible with the Pacman package. You can describe the necessary dependencies and make the installation process very easy.

For example, Sublime Text has only one option to download a DEB package or a tarball with the binaries. The same goes for Spotify, Franz, etc. Sometimes you can save personal package files (PPA) and then use them to install them. But you still need someone to build, maintain and distribute these packages correctly. It is a lot of work

Now, keeping a simple Git repository with a simple PKGBUILD text file is much easier. makepkg does the hard work of building the package you need, on your machine, and then Pacman can handle the installation like any other package. No more fortune files and manual configuration of everything!

Maybe you finally Pacman-Suyu and have everything “really” improved without having to worry about the next big LTS asking you to reinstall everything from scratch.

Over the years, the Arch community has continued to grow and has recently received an unusual amount of attention and comments from various stakeholders for a modest-sized Linux distributon.

CENTOS LINUX And the Cool Operating System It is.

Free Operating System Linux

CentOS (the community’s commercial operating system) is a Linux distribution that tries to provide a free, enterprise-class, community-compatible computing platform that is functionally compatible with its source, Red Hat Enterprise Linux (RHEL). In January 2014, CentOS announced the official union with Red Hat while remaining independent of RHEL, under a new CentOS board.

The first version of CentOS in May 2004, numbered in CentOS version 2, is derived from RHEL version 2.1AS. Ever since the release of version 7.0, CentOS only officially supports the x86-64 architecture, while the previous version prior version 7.0-1406 also supports the IA-32 with the extension of the address Physics (PAE). Since December 2015, AltArch versions of CentOS 7 are available for the IA-32 architecture, the Power architecture and the ARMv7hl and AArch64 variants of the ARM architecture.

CentOS repositories

There are three main CentOS repositories (also called channels), which contain software packages that make up the main CentOS distribution:

Base: includes packages that form CentOS point launches and is updated when the actual version of the point is officially available as ISO images.

Updates: Contains packages that serve as security updates, bug fixes, or enhancements, issued between regular updates for point versions. Error and enhancement updates published in this manner are only those that can not be released through the CentOS-Fasttrack repository.

Add-ins: Provides the packages necessary to compile the packages that make up the primary CentOS distribution, but the upstream stream does not provide that.

The CentOS project provides several additional repositories that contain software packages not offered by the default database and update repositories. These standards are the following:

CentOS Extras: Contains packages that provide additional functionality to CentOS without breaking backward compatibility or updating the core components.

CentOSPlus: Contains packages that update some basic CentOS components, changing CentOS so that it is not exactly like the content of the upstream provider. CentOS-Testing: serves as a test field for en route packages to CentOSPlus and CentOS Extras. The proposed packages may or may not replace the main CentOS packages and are not guaranteed to work correctly.

CentOS-Fasttrack – contains bug fixes and improvements released from time to time, between regular updates for specific versions. The packages thus released serve as close candidates for inclusion in the next publication. This repository does not provide security updates and does not contain packages that are not suitable for uncertain inclusion in single versions.

CR (Continuous Release): provides packages that will appear in the next version of CentOS. Packages are available in the form of a trial and patch until the publication of the actual point is officially published as ISO images.

debuginfo - contains packages with debugging symbols generated during the creation of main packages

contrib - contains packages provided by CentOS users that do not overlap any of the major distribution packages

Software collections: provides software versions that are newer than those provided by the Basic Distribution, see above for more details

Why you should Use centOS

An open source version of Red Hat Enterprise Linux, CentOS is just about everything that can be expected from a corporate distribution, but it is still open source. Developed and designed to be fundamentally similar to Red Hat, CentOS runs only the most stable versions of packaged software. This greatly reduces the risk of failures and errors.

Users who install CentOS also have access to a dozen security updates at the enterprise level, due to their close connection to Red Hat. This means that CentOS is equipped with a wide range of impressive security features, including an incredibly powerful firewall and the SELinux policy mechanism. Factor in the greater stability enjoyed by the distribution and this becomes an even more attractive option.

CentOS offers superior reliability, speed and stability.

Now, it’s worth mentioning that CentOS does not necessarily need new versions as often. The superior stability of the platform means that it faces fewer errors and security holes than other distributions in the market, while it can run longer without the need for new hardware upgrades.

LINUX TRUEOS AND IT COOL FEATURES

Free Operating System Linux

TrueOS was originated by FreeBSD professional Kris Moore as a PC-BSD in early 2005. In august 2006, TrueOS was voted as the most user-Friendly operating system by OSWeekly.com,

The first beta version of PC-BSD consisted of a single GUI installer to put the user into service with a pre-configured KDE3 FreeBSD 6 system. This was an important innovation at the moment since anyone who wants to install FreeBSD should manually change it and run it through a text installer. Kris Moore’s goal was to make FreeBSD easy to use for everyone on the desktop, and since then it has diverged in usability by including additional graphical management tools and .pbi application installers. Administering the PC-BSD application installer involved a different approach to software installation than several other Unix-like operating systems, up to Version 8.2, via the pbiDIR website. Instead of directly using the FreeBSD port tree (although it was still available), PC-BSD used files with the .pbi file name extension (Button Installer) which, by double-clicking, displayed a setup wizard program A self-build system tracked the FreeBSD port collection and generated new .pbi files daily. All packages and dependencies have been installed from .pbi files into their standalone directories or Programs.

This convention was designed to reduce confusion about the location of binary programs and to eliminate the eventuality of breaking a package if system libraries are updated or modified, and to avoid dependency.

PC-BSD was acquired by the enterprise-class hardware solutions provider iXsystems On October 10, 2006. iXsystems employed Kris Moore as a full-time developer and project manager. In November 2007, iXsystems signed a distribution agreement with Fry’s Electronics in which Fry’s Electronics records PC-BSD version 1.4 (Da Vinci Edition) copies in the country. In January 2008, iXsystems entered into a similar agreement with Micro Center.

The PC-BSD team broadcasted that the name of the operating system would become TrueOS On September 1st, 2016. With the change of brand, the project also became a mobile version distribution, based on the FreeBSD-CURRENT branch.

On November 15, 2016, TrueOS began the rc.d transition from FreeBSD to OpenRC as the default boot system. In addition to Gentoo / Alt, where OpenRC was originally developed, it is the only other operating system based on BSD that uses OpenRC.

Amazing Features Of Linus TrueOS

What makes TrueOS different from other OS? TrueOS is centered on the legendary security and stability of FreeBSD. TrueOS follows FreeBSD-CURRENT, with the latest drivers, security updates, and available packages. Also, it new driver package supports new Intel chipsets and new graphics hardware. It offers industry-leading features such as PersonaCrypt, which allows you to encrypt your user’s home directory and transfer it to other TrueOS machines. TrueOS also supports GELI hard drive encryption, ensuring the security of your data, even in the event of physical theft.

  • TrueOS is based on FreeBSD to make the best desktop possible by incorporating these incredible additions at the system level:

  • TrueOS uses LibreSSL for everything

  • Complete clang functionality built from ports

  • TrueOS updates use boot environments and never touch your online system

  • Linux DRM 4.9 (Support for Modern Intel Graphics – Broadwell, Skylake)

  • Ports and packages compiled with more options.

Safe and secure

Let’s face it: data security is one of the most complex problems an operating system faces to protect users. That’s why, as part of the TrueOS project, everything was made possible to ensure that you have all the utilities you need for keeping your systems safe. Users can create a portable but fully encrypted home directory on a removable USB drive that can be moved between TrueOS systems Using GELI Hard Disk Encryption with PersonaCrypt. This allows you to have all your data with you, regardless of the computer system you use. We can use LibreSSL, which is widely known and used in OpenBSD, to secure our code base and increase security at the central level.

SysAdm ™ Remote Management

SysAdm offers a new way to manage your server, desktop, or cloud systems. By revealing an API via encrypted REST or WebSockets, it is now possible to remotely control all aspects of your machine, including software administration, updates, boot environments, users, backups and more. SysAdm is the answer for businesses looking for a cost-effective but scalable solution that easily manages different segments of the IT infrastructure to keep things running smoothly. TrueOS has now incorporated all local and remote control panel functions into SysAdm so that it can easily find and adjust any configurable element of the system from one location.

The OpenZFS file system

The next evolution of file systems is the OpenZFS file system. The revolutionary ZFS design incorporates elements of copying over writing and self-healing to provide rock-solid reliability. However, boot environments make this file system shine. With boot environments, you can quickly take a picture of your system’s configuration at any time. If something goes wrong during an update, or if you have edited a configuration file, you should not have it, do not worry! Simply use the integrated undo feature to return to the previous boot environment and be on the way. OpenZFS provides integrated software RAID without the need for expensive hardware drivers.

The origination of TrueOs from 2005 till date, has shown that trueOs has helped users in various ways, such as legendary security and stability of FreeBSD, driver support for new intel chips, supports for GELI hard drive encryption, ensuring the security of your data even in the event of physical theft and more. Many users have positively rated and commended on these awesome features of TrueOs.
