About this capture

COLLECTED BY

Organization:Archive Team

Formed in 2009, the Archive Team (not to be confused with the archive.org Archive-It Team) is a rogue archivist collective dedicated to saving copies of rapidly dying or deleted websites for the sake of history and digital heritage. The group is 100% composed of volunteers and interested parties, and has expanded into a large amount of related projects for saving online and digital history.

History is littered with hundreds of conflicts over the future of a community, group, location or business that were "resolved" when one of the parties stepped ahead and destroyed what was there. With the original point of contention destroyed, the debates would fall to the wayside. Archive Team believes that by duplicated condemned data, the conversation and debate can continue, as well as the richness and insight gained by keeping the materials. Our projects have ranged in size from a single volunteer downloading the data to a small-but-critical site, to over 100 volunteers stepping forward to acquire terabytes of user-created data to save for future generations.

The main site for Archive Team is atarchiveteam.org and contains up to the date information on various projects, manifestos, plans and walkthroughs.

This collection contains the output of many Archive Team projects, both ongoing and completed. Thanks to the generous providing of disk space by the Internet Archive, multi-terabyte datasets can be made available, as well as in use by theWayback Machine, providing a path back to lost websites and work.

Our collection has grown to the point of having sub-collections for the type of data we acquire. If you are seeking to browse the contents of these collections, the Wayback Machine is the best first stop. Otherwise, you are free to dig into the stacks to see what you may find.

The Archive Team Panic Downloads are full pulldowns of currently extant websites, meant to serve as emergency backups for needed sites that are in danger of closing, or which will be missed dearly if suddenly lost due to hard drive crashes or server failures.

Synopsis

Cyclone is a programming language based on C that issafe, meaning thatit rules out programs that have buffer overflows, dangling pointers,format string attacks, and so on. High-level, type-safe languages, such as Java, Scheme, or ML also provide safety, but they don't give the same controlover data representations and memory management that C does (witness the fact that the run-time systems for these languagesare usually written in C.) Furthermore, porting legacy C code to these languages or interfacing with legacy C libraries is a difficult and error-prone process. The goal of Cyclone is to give programmersthe same low-level control and performance of C without sacrificingsafety, and to make it easy to port or interface with legacyC code.

Cyclone achieves safety while remaining compatible with C by:

• Enforcing type safety (e.g., a cast from t1 to t2 is allowed only if itis safe to view a t1 as at2)
• Not changing datarepresentation or calling conventions
• Providing region-based, manual memory management
• Using a combination of type information and run-time checks toprevent array-bound violations
• Wrapping the C standard library with appropriate run-time checksas necessary (e.g., has a FILE already been closed)

• Tagged unions
• Parametric polymorphism
• Pattern matching
• Exceptions
• Anonymous structs equivalent by structure
• Parameterized typedefs
• An extensive library for container types and other common utilities
• A lexer generator and parser generator
• Function-level debugging with gdb and profiling with gprof

Software Distribution

The Cyclone compiler and tools, as well as some benchmark programs, are freely available for download.

System Requirements:

• Cyclone is currently supported on x86 Linux, and on Windows usingCygwin (version 1.3.3). Otherplatforms may or may not work (our install process tries to detectyour configuration and automatically create the necessaryplatform-specific information).  We have had some success on BSD, Irix, and Solaris systems, but your mileage may vary.  In particular, system-dependent behavior is largely untested.
• You need to extract the files from the "gzippedtarball" using gunzip and tar; under Windows, you can also dothis with Winzip.
• You need GNU make, a fairly recent version of gcc (we recommendversion 2.95), a bash or ksh shell, and various common utilities (awk, sed,grep). If you are using Cygwin, all of these come with it. gcc andthe utilities must be in your path. Other make programs and Ccompilers willnot work.
• See the file INSTALL in the distribution for details.

Licensing: The files in the distribution come froma variety of sources and so come under a variety of licenses. Pleasesee each file and directory for its licensing terms.
