A site where information technology professionals share strange computer related dreams they've had.
A column from Scientific American about the workings of the Tinker Toy tic-tac-toe playing computer. How the game logic works, how the memory bank is encoded, and other interesting details.
Music and graphics featuring an 8-bit computer aesthetic.
"Sticks and stones may break your bones, and they make surprisingly cool fonts!" JPEG and TrueType found (in nature) object fonts.
"The Alphabet Synthesis Machine is an interactive online artwork which allows one to create and evolve the possible writing systems of one's own imaginary civilizations. The abstract alphabets produced by the Machine can be downloaded as PC-format TrueType fonts, and are entered into a comprehensive archive of user creations. The products of the Machine probe the liminal territories between familiarity and chaos, language and gesture."
So recent yet so old. TRS-80 Model 1 RAM (32K) expansion pack -- $359.95 -- "lowest price ever", etc.
"An analog computer is a computing device that has two distinguishing characteristics: (1) Performs operations in a truly parallel manner. Meaning it can perform many calculations all at the same time. (2) And operates using continuous variables. Meaning it uses numbers that that change not in steps, but change in a smooth continuous manner. By constrast, a digital computer can only perform sequential (one at a time) operations, and operates on discrete (noncontinuous) numbers."
Made about 850CE, this computer uses ropes and pulleys to make the logic gates.
Piet is a computer language that uses colors as operators and graphics as programs. It is named for Piet Mondrian, the modern artist, because the programs bear some resemblence to his art.
A site devoted to all things Atari ST, downloads, games, reviews, scans of software boxes, etc.
An open source tool to generate random computer science papers, from some MIT students.
When my twelve year old came to me looking for ways to make computer games, I applied my Google-fu and found this free (open source, open license) game development tool, based on the free (some sort of attribution license) Genesis3D modeling components. It runs on Windows XP, doesn't require C or C++ programming, and produces "Quake 2 dungeon crawl clone" games. A far cry from my 8-bit (and lower) youth, but initial impressions are good.
Heritrix is an open-source archival web-crawler.
"Heritrix (sometimes spelled heretrix, or misspelled or missaid as heratrix / heritix / heretix / heratix) is an archaic word for inheritess. Since our crawler seeks to collect the digital artifacts of our culture for the benefit of future researchers and generations, this name seemed apt."
Perhaps the best source for old web browser software. Need to see how Netscape 2.x would display a page? Want to give Mosaic a whirl? Find those browsers and many more here.
Suddenly bookmarks from a context menu seems much more useful.
A nice little site targeting "old-tech and low-spec games and machines" such as 8-bit game consoles, Game Boys, etc. Has indespensible ROM files for system BIOS, etc. (No game ROMs.)
An opensource x86 on x86 system emulator. This is a "lightweight" emulator designed only to run Linux under Linux.
The big name in virtual machines to run Windows, Linux, etc, on i86 hardware. Expensive, but well polished with nice features like revert to snapshot, etc.
Netraverse is the maker of Win4Lin a commercial application to run Windows apps under linux. Requires Windows to install on the virtual system. Much cheaper than VMware, but fewer features.
A portable IA-32 (x86) machine emulator capable of running common operating systems like Linux, Windows 95, and Windows NT.
"SFS is a network file system that provides strong security over untrusted networks. At the same time, SFS goes to great lengths to prevent security from hurting performance or becoming an administrative burden."
A page I made extolling the virtues of the Portable Video Research Group JPEG implementations. This is an old and obscure tool that I feel needs more recognition.
The comp.graphics.misc frequently asked questions list, with answers, about JPEG compression and JFIF files. Last modified in 1999, some of the questions are quite dated, but many are still relevant.
The W3C page on the image/jpeg file format is brief, but it has links to two PDF files documenting the JPEG FIle Format, the standard way to contain images compressed with the JPEG mechanism.
An organization (or individual?) that provides improvements to jpeg manipulation tools, such as tweaking the ILJ 'cjpeg' compressor to allow different compression quality settings on different channels.
A good non-mathematically introduction to the technical aspects of JPEG compression, with lots of illustrations of what different settings do to images.
The 1987 Dougherty and O'Reilly book on the text processing tools of Unix has been released under a Creative Commons Attribution license. This site is coordinating the effort to recreate the book in groff source from page scans.
Documentation, tutorials, etc, for groff/troff and related tools.
Selected (by virtue of easy electronic access) Bell Labs papers, many of which deal with Unix or Unix utilies. Eg, #54, "Nroff/Troff User's Manual" by Ossanna with Kernighan revisions and #123 "C Traps and Pitfalls" by Koenig, later adapted into a book of the same name. Many of these are gziped postscript files.
"The Unix Heritage Society's aims include:
* The preservation and maintenance of historical and non-mainstream UNIX systems;
* The further development of existing UNIX systems; and
* The continual fostering of the Unix community spirit."
Timeline of many Unix flavors and links to many other Unix history resources.
Links to several sets of manpages for old versions of Unix, going back to Unix Seventh Edition.
All about Unix, a paper published in the Communications of the ACM in 1974, by D. M. Ritchie and K. Thompson.
A GPL virus scanner to run on your Unix box. Even if your Unix box won't be infected by Windoze viruses, it still suffers under the waste of disk space. Stop them as they come in with this.
pcal is an old but well updated postscript calendar generator. It has lots of bells and whistles to print nice looking calendars. You need to provide your own photos to put above each page, though. :^) lcal is a companion utility that prints lunal phase calendars.
This is my favorite image viewer. It has the standard features such as thumbnail views and slideshow modes, but it also can fetch files with wget and reload periodically for webcams, etc.
This is a command line tool to make an image from some text using most any font.
Macro software for X Windows.
