Jef Poskanzer
Jeffrey A. Poskanzer is a computer programmer. He was the first person to post a weekly FAQ to Usenet. He developed the portable pixmap file format and pbmplus (the precursor to the Netpbm package) to manipulate it. He has also worked on the team that ported A/UX. He has shared in two USENIX Lifetime Achievement Awards – in 1993 for Berkeley Unix, and in 1996 for the Software Tools Project. He owns the Internet address acme.com (which is notable for receiving over one million e-mail spam Email spam, also referred to as junk email, spam mail, or simply spam, is unsolicited messages sent in bulk by email (spamming).

Usenet
Usenet () is a worldwide distributed discussion system available on computers. It was developed from the general-purpose Unix-to-Unix Copy (UUCP) dial-up network architecture. Tom Truscott and Jim Ellis conceived the idea in 1979, and it was established in 1980.''From Usenet to CoWebs: interacting with social information spaces'', Christopher Lueg, Danyel Fisher, Springer (2003), , Users read and post messages (called ''articles'' or ''posts'', and collectively termed ''news'') to one or more topic categories, known as newsgroups. Usenet resembles a bulletin board system (BBS) in many respects and is the precursor to the Internet forums that have become widely used. Discussions are threaded, as with web forums and BBSs, though posts are stored on the server sequentially.The jargon file v4.4.7 , Jargon File Archive.

Portable Pixmap
Netpbm (formerly Pbmplus) is an open-source package of graphics programs and a programming library. It is used mainly in the Unix world, where one can find it included in all major open-source operating system distributions, but also works on Microsoft Windows, macOS, and other operating systems. File formats Several graphics formats are used and defined by the Netpbm project. The portable pixmap format (PPM), the portable graymap format (PGM) and the portable bitmap format (PBM) are image file formats designed to be easily exchanged between platforms. They are also sometimes referred to collectively as the portable anymap format (PNM), not to be confused with the related portable arbitrary map format (PAM). The "magic number" (Px) at the beginning of a file determines the type, not the file extension, although it is best practice to use the right extension if possible. The PBM format was invented by Jef Poskanzer in the 1980s as a format that allowed monochrome bitmaps to b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

A/UX
A/UX is Apple Computer's Unix Unix (; trademarked as UNIX) is a family of multitasking, multiuser computer operating systems that derive from the original AT&T Unix, whose development started in 1969 at the Bell Labs research center by Ken Thompson, Dennis Ritchie, a ...-based operating system for Macintosh computers, integrated with System 7's graphical interface and application compatibility. Launched in 1988 and discontinued in 1995 with version 3.1.1, it is Apple's first official Unix-based operating system. A/UX requires select Motorola 68000, 68k-based Macintosh models with an Floating point unit, FPU and a paged memory management unit (PMMU), including the Macintosh II, Macintosh SE/30, SE/30, Macintosh Quadra, Quadra, and Macintosh Centris, Centris series. Described by ''InfoWorld'' as "an open systems solution with the Macintosh at its heart", the operating system is based on UNIX System V Release 2.2. It includes some additional features from System V Release ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
E-mail Spam
Email spam, also referred to as junk email, spam mail, or simply spam, is unsolicited messages sent in bulk by email (spamming). The name comes from a Monty Python sketch in which the name of the canned pork product Spam is ubiquitous, unavoidable, and repetitive. Email spam has steadily grown since the early 1990s, and by 2014 was estimated to account for around 90% of total email traffic. Since the expense of the spam is borne mostly by the recipient, it is effectively postage due advertising. This makes it an excellent example of a negative externality. The legal definition and status of spam varies from one jurisdiction to another, but nowhere have laws and lawsuits been particularly successful in stemming spam. Most email spam messages are commercial in nature. Whether commercial or not, many are not only annoying as a form of attention theft, but also dangerous because they may contain links that lead to phishing web sites or sites that are hosting malware or includ ...

Thttpd
thttpd (tiny/turbo/throttling HTTP server) is an open source software web server from ACME Laboratories, designed for simplicity, a small execution footprint and speed. Design and features thttpd is single-threaded and portable: it compiles cleanly on most Unix-like operating systems, including FreeBSD, SunOS 4, Solaris 2, BSD/OS, Linux, and OSF/1. It has an executable memory size of about 50 kB. While it can be used as a simplified replacement to more feature-rich servers, it is uniquely suited to service high volume requests for static data—for example as an image hosting server. The first "t" in thttpd stands for variously tiny, turbo, or throttling. thttpd has a bandwidth throttling feature which enables the server administrator to limit the maximum bit rate at which certain types of files may be transferred. For example, the administrator may choose to restrict the transfer of JPEG image files to at most 20 kilobytes per second. This prevents the connection f ...

Described by ''InfoWorld'' as "an open systems solution with the Macintosh at its heart", the operating system is based on UNIX System V Release 2.2. It includes some additional features from System V Releases 3 and 4 and BSD versions 4.2 and 4.3. It is POSIX- and System V Interface Definition (SVID)-compliant and includes TCP/IP networking from version 2 onward. Having a Unix-compatible, POSIX-compliant operating system made it possible for Apple to bid for large contracts to supply computers to U.S. federal government institutes. Features ...
