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.

Filezilla Free Software For Website Hosting

FileZilla is a free FTP multiplatform application for free software, which consists of FileZilla Client and FileZilla Server. The binaries of the client are available for Windows, Linux and MacOS, and the binaries of Servidor están are available for Windows. The client admits FTP, SFTP and FTPS (FTP over SSL / TLS).

Im Kosse and two of his colleagues launched FileZilla as a class project in January 2001. It was born in February 2001. It was written in C ++ and wxWidgets. It is available in the multilingual language and is of the FTP client type. People who can not manage sites use FTP options. Website owners who want to reduce their efforts and have more control over website creation and administration tools should use FTP options. File transfer protocol (FTP). The benefit of this procedure is that it saves time by replacing the manual update. In 2011, FileZilla was ranked as the most downloaded by online users. This platform facilitates the updating, editing and deletion of files.

There are five outstanding features of FileZilla:

Directory comparison: the contents of several local and remote directories can be compared using FileZilla.

Recording: message records can be displayed in the window at the top. Show the commands and responses sent by FileZilla.

Site administrator: this tool is the most used by users. The user can create an FTP site account, in combination with the connection data, the port number and the protocol to be used, etc.

Transfer queue: shown in the window at the bottom, the files are active or queued.

Folder view and file view: this feature provides a GUI for FTP. It is easy to browse and view folders, and transferring files between computers are also easier.

FileZilla has several advantages that it offers to its users on the features provided by other tools used to create sites. The plethora of benefits include:

Available in several languages.

Easy synchronization of local and remote directories.

Availability of features such as bookmarks, wizards for network configuration, configurable transfer speed limits, and the remote file editing option.

The benefits of FileZilla are a lot more than the disadvantages.

The problem of scripts can be a problem. There is no way to request scripts, either internally or via a common line. It is only supported manually or with interaction.

Another disadvantage of FileZilla is that previous versions do not use Windows 9X / ME. Use Unicode.

New versions of FileZilla binaries use Mac OSXv10.5. Do not admit anything “tiger” or time before. You need a compilation of ‘Leopard’.

Another important problem is that timestamps can be a big problem. If the server supports the MFMT command, the timestamps can be retained.

Another big problem with this software is that timestamps can be downloaded if the timestamps are compatible with the partition that supports timestamps for the file’s creation, date, and time.

For Microsoft Windows, the FileZilla server is completely free and an open source FTP server. SourceForge.net is the source code that hosts the FileZilla server. FTP and FTPS are compatible with the server. Compression, virtual file system, message logs, TLS / SSL encryption, and download of bandwidth limits are the functions of the server. Large companies like HostGator and GoDaddy are compatible with FileZilla. The reason for the popularity of FileZilla is that it is free and has an open source. The best feature is that it is user-friendly and easy for beginners and complex and advanced for experienced users.

Gimp Free Graphics Design Studio

GIMP is a versatile graphics manipulation package. It is a free distribution program for tasks such as photo editing, image composition and image creation. The terms of use and the copy rules are listed in the GNU General Public License. GIMP is a versatile graphics manipulation package.

GIMP (GNU Image Manipulation Program) is regarded as a free open source raster graphics editor used to edit and edit images, draw freely, convert between different formats image and more specialized tasks.

GIMP was initially published as a universal image manipulation program. In 1995, Spencer Kimball and Peter Mattis began to develop GIMP as part of a semester project at the California University at Berkeley for the experimental installation of computers. In 1996, GIMP (0.54) was launched as the first available publication. The following year, the definition of the acronym GIMP was changed to be the GNU Image Manipulation program. This reflected his new existence as free software under the GNU project.

AWESOME FEATURES OF GIMP

  • Customizable interface

Every single task requires a different environment and GIMP allows you to customize the view and behaviour as you wish. From the theme of the widget, allowing you to change the colors, the spacing of the widgets and the sizes of the icons in custom tool sets in the toolbox. The interface is modulated in springs, which allows you to stack them in tabs or keep them open in your window. You can press the Tab key to disable them.

GIMP has an excellent full-screen mode that not only allows you to preview your artwork but also does editing work while using most of your screen.

  • Improved photo

Many imperfections of digital photos can be easily compensated by using GIMP. The distortion of the perspective caused by the tilt of the lens was corrected by simply choosing the correction mode in the transformation tools. Eliminates distortion of the lens barrel and vignetting with a powerful but a simple interface.

The built-in channel mixer gives you the flexibility and power to make your black and white photography stand out the way you want.

  • Digital Retouching

GIMP is ideal for advanced photo editing techniques. Get rid of unnecessary details using the cloning tool, or easily retouch minor details with the new healing tool. With the cloning tool in perspective, it is not difficult to clone objects with the prospect in mind as quickly as with the orthogonal clone.

  • Material support

GIMP includes very exclusive support for several ready-to-use input devices. Tablets sensitive to pressure and tilt, but also a wide range of USB or MIDI controllers. You can link frequently used actions to device events, such as rotating a USB wheel or moving the cursor on a MIDI controller. Change the angle, size, or opacity of a brush while you paint, and associate your favorite scripts with buttons. Speed ​​up your workflow!

  • File formats

Support for the file format extends from common JPEG (JFIF), GIF, PNG, TIFF format to special formats, such as Windows icon files with multiple resolutions and multi-colour depth. The architecture extends GIMP’s format capabilities with a plug-in. You can find bizarre format support in the GIMP plugin registry.

Thanks to the transparent virtual file system, protocols such as FTP, HTTP or even SMB (MS Windows sharing) and SFTP / SSH makes it possible to download and save files from remote locations.

Saving disk space, any format can be backed up with a file extension such as GZ, or BZ2, ZIP and GIMP will compress the file seamlessly without requiring additional steps.

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. ”

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.
