Arachne. Graphical web browser for DOS
Operating systems : MS-DOS 6.0+, FreeDOS 1.0+
Arachne is a full-screen graphical web browser for DOS on PC computers. Originally developed by Michael Polák. First release - 22th December 1996. The last Arachne version by Arachne Labs was released on 22th January 2001. Arachne source code was opened in November of 2003 and the subsequent versions are released under GNU GPL license.
Arachne is distributed as a software suite containing, besides web browser, built-in e-mail client, FTP, internet connection wizard, WAV files player. More add-ons are available: image viewer, PDF, file managers, mplayer, Telnet client, IRC and more.
Arachne supports Windows-1251 and KOI8-R Cyrillic after additional packages are installed. Internet connection is via serial ports (COM) and Ethernet. There are also Arachne for Linux / SVGAlib.
GPL versions of Arachne. The main line of Arachne development. Major changes and updates take place within its framework. Maintained by a group of enthusiasts who also develop GPL version for Linux / SVGAlib.
Arachne Labs versions. Arachne Labs, xChaos software initially, were the main structure engaged in development of Arachne until 2003, when Arachne source code was opened and the GPL versions of the browser became the main line. The last Arachne Labs version was released on 22th January 2001: Arachne 1.70 Release 3.
Ray Andrews version. A GPL Arachne variation.
PTS-DOS version. Similar to the corresponding versions of Arachne, but to some extent integrated with the PTS-DOS distribution.
DR-WebSpyder. Based on Arachne. Basically - different web browser, for which Arachne is just an ancestor. Later the browser was renamed as Lineo EmBrowser.
Arachne web browser was created in DOS and for DOS (the Linux version stands somewhat apart). Therefore, even though Arachne will run under many versions of Windows, Windows XP for instance, it is working under DOS when Arachne qualities are revealed best.
Arachne web browser works in all major DOS variants, for example MS-DOS, FreeDOS or PTS-DOS.
System requirements are low. The minimum: 80x86 CPU, 500 KB DOS base memory, 1 MB XMS/EMS memory, 512 KB SVGA video, 5 MB HDD space. Although requirements for using maximum screen resolution, maximum color depth are higher. But in this case too they are extremely small by today's standards - 486, better Pentium I computer, 640 KB base memory, 8+ MB XMS/EMS memory, 2+ MB SVGA video. Yet it depends - using 640x480 screen resolution, installing Arachne on RAM disk let to have Arachne running quite well on 386 CPU computer; if only there are enough of RAM and video adapter capabilities.
Besides traditional hard disk installation, DOS LIVE CD by Roman Karpach may be used ( www.fdd5-25.net/doslivecd ), where Arachne web browser is among the software present.
The characteristics of Arachne web browser installation process make the main settings be set right from the beginning. These settings for the most part are the responsibility of operating system on computers running Windows, Mac OS X or Linux, but in DOS Arachne browser takes care of everything itself. So at the end of installation Arachne web browser is ready for use right away - in a specific, selected during installation process mode: for internet connection via COM port, for internet connection via network adapter, for browsing local files only.
Later, after installation is complete and settings are set, Arachne web browser can be reconfigured into any possible mode. But at first, Arachne is configured for either internet connection via COM port or internet connection via network adapter or the function of connecting to internet is turned off. Therefore further discussed:
The case when Arachne web browser is configured for browsing local files only is not discussed, since it is a simplified form of the first two.
When a widescreen LCD computer display (a LCD with aspect ratio more than 4:3, like 16:9) is used, one needs to know if the display supports aspect scaling / pillarboxing. If yes - how. The maximum screen resolution supported by Arachne web browser is 1024x768. So, to prevent image to be distorted in LCD, aspect scaling / pillarboxing has to be employed.

MPlayer : FFmpeg Media players appeared long ago, but their heyday began with the mass spread of personal computers powerful enough to play video files. This coincided with the mass spread of operating systems and other software with graphical user interface. However, a program with a graphical user interface is dualistic in its nature: there is a code responsible for graphical user interface, for the appearance and there is a code - for performing the task the given application has been created for in the first place. Both code complexes consume system resources, their response time to user actions makes up certain amount of waiting time. And in cases or concepts when appearance is taken as less important - less important to the point of sparing or almost sparing to employ it - console applications, among others, appear. Moreover, the segmentation of the GUI and of the engine makes it easier to change the graphical user interface or perform complex automated operations. The scheme is implemented for media players for Windows as well. MPlayer, for instance, in its usual form is a console application, starting up quickly, having fast response to user actions, consuming system resources almost entirely for its immediate task. And on this basis if desired, one or another graphical interface may be added for creating, all in all, a new application. MPlayer - / home page / Console media player for Windows. Basis for SMPlayer and UMPlayer. There are versions for Linux, FreeBSD, NetBSD, OpenBSD, Apple Darwin, Mac OS X, QNX, OpenSolaris/Solaris, Irix, HP-UX, AIX, some other *nix system, BeOS, Syllable, AmigaOS, AROS, MorphOS, DOS, Windows. Supported video, audio formats, static images, subtitles, etc. ( List and More extensive list of video and audio codecs ). MPlayer: "Dead Man" MPlayer: "Sky Captain and the World of Tomorrow" MPlayer: "10,000 BC" MPlayer: "13 Tzameti" MPlayer: "The Draughtsman's Contract" MPlayer: "Balzaminov's Marriage" FFmpeg - / home page / Pack of utilities and libraries for work with video and audio files. Created in and for Linux, but there is a Windows variant. Source code may be compiled for some other operating systems. Supported file formats and codecs: ( List ). Also, VLC media player can be run in text mode, ncurses using.
