Some Unix-based implementations ( CLISP, SBCL ) can be used as a scripting language ; that is, invoked by the system transparently in the way that a Perl or Unix shell interpreter is.

Some early examples of computer markup languages available outside the publishing industry can be found in typesetting tools on Unix systems such as troff and nroff.

( Some legacy operating systems, including early versions of Unix and Windows, limited passwords to an 8 character maximum, reducing security.

Some operating systems such as early versions of Unix did not support attaching debuggers to running processes, so core dumps were necessary to run a debugger on a process's memory contents.

Some Unix shells use the ampersand as a metacharacter:

Some Unix shells, like the POSIX standard shell, use the ampersand to execute a process in the background and to duplicate file descriptors.

Some Unix as well as Linux distributions use symbolic links extensively in an effort to reorder the file system hierarchy.

Some Usenet newsreaders, especially in the Unix world, have tried to make it easier to find interesting postings and filter useless ones.

Some early Unix systems at Bell Labs used GCOS machines for print spooling and various other services.

Some operating environments for programming purposes are referred as programming environments ; e. g., the " UNIX programming environment " for a Unix shell with its look and feel and functionality.

Some Unix variants, such as AT & T UNIX System V Release 3. 0 include the related < tt > setname </ tt > program, used to change the values that uname reports.

Some Unix, BSD, and Linux distributions also include DNS-SD functionality.

Some platforms provide library calls which allow run-time dynamic allocation from the C stack rather than the heap ( e. g. Unix, Microsoft Windows CRTL's ).

Some versions of these later Intel-based machines ran Windows NT, while higher-end machines ran the company's flavor of Unix, DG / UX.

Some versions of Unix use a relatively expensive implementation of the crypt library function for hashing an 8-character password into an 11-character string.

Some of the important developments made at SRC include the Modula-3 programming language ; the snoopy cache, used in the first multiprocessor workstation, the Firefly, built from MicroVAX 78032 microprocessors ; the first multi-threaded Unix system, Taos ; the first user interface editor ; the first networked window system, Trestle.

Some SMRs are simple card indexes, others are command line Unix databases and others are more modern and GIS-based.

Some SSI systems provide the illusion that all processes are running on the same machine-the process management tools ( e. g. " ps ", " kill " on Unix like systems ) operate on all processes in the cluster.

Some of the languages with support for foreach loops include ABC, ActionScript, Ada, C ++ 11, C #, Cobra, D, Daplex ( a query language ), ECMAScript, Java ( since 1. 5, using the reserved word for the for loop and the foreach loop ), JavaScript, Objective-C ( since 2. 0 ), Perl, PHP, Python, REALbasic, Ruby, Smalltalk, Tcl, tcsh, Unix shells, Visual Basic. NET and Windows PowerShell.

Some of the salient characteristics that distinguish Hartmann Pipeline from ordinary Unix pipes are:

Some variants of Unix support options such as and.

Some Unix systems behave differently in this mode, depending on the termination of directory paths.

Some educated parties note that the USL v. BSDi case had shown that the Unix copyrights are weak and unenforceable.

Some of GLUT's original design decisions made it hard for programmers to perform desired tasks.

Some programmers still use makefiles and their derivatives.

Some studies have found that programmers working in pairs produce shorter programs, with better designs and fewer bugs, than programmers working alone.

Some real-time software 3D engines based on ray tracing have been developed by hobbyist demo programmers since the late 1990s.

Some programmers feel that these syntax usability features are either unimportant or outright frivolous.

Some programmers, including Dan Bernstein, getmail creator Charles Cazabon and FreeBSD developer Terry Lambert, have criticized Fetchmail's design, its number of security holes, and that it was prematurely put into " maintenance mode ".

Some programmers consider the " p-code " generated by some Pascal compilers, as well as the bytecodes used by. NET, Java, BASIC and some C compilers to be token-threading.

Some compilers in this category provide special constructs or extensions to allow programmers to directly specify operations to be performed in parallel ( e. g., DO FOR ALL statements in the version of FORTRAN used on the ILLIAC IV, which was a SIMD multiprocessing supercomputer ).

Some manufacturers avoid this problem by explicitly and completely defining the execution order of a rung, however programmers may still have problems fully grasping the resulting complex semantics.

Some programmers who had worked on the original ICS became unhappy with what they saw as the commoditization of their project.

Some authors – see, for example, Creating a Software Engineering Culture by Karl E. Wiegers – have stressed the importance of the social and political aspects of the work climate as determinants of the effectiveness of individual programmers and the project team as a whole.

Some languages ( e. g. C ++) leave this to programmers.

Some programmers such as Jamie Zawinski feel that spaces instead of tabs increase cross-platform functionality.

Some programmers may specialize in one area of game programming, but many are familiar with several aspects.

Some physics programmers may even delve into the difficult tasks of inverse kinematics and other motions attributed to game characters, but increasingly these motions are assigned via motion capture libraries so as not to overload the CPU with complex calculations.

Some of those programmers attended the OOPSLA and PLoP conferences about object-oriented programming, posting their ideas on the PPR and exchanging e-mail messages with Ward.

Some early programmers combined instructions and data in words as a way to save memory, when it was expensive: The Manchester Mark 1 had space in its 40-bit words to store little bits of data – its processor ignored a small section in the middle of a word – and that was often exploited as extra data storage.

Some programmers nicknamed the finished product LOL memory, for Little Old Lady memory.

Some device programmers serve a double purpose for programming as well as debugging the device.

Some assembly language programmers reject HLA out of hand because it allows programmers to do this.

Some systems will e-mail interested parties, such as the submitter and assigned programmers, when new records are added or the status changes.

Some uncreative programmers would create game quests in which the goal was to guess the proper syntax to an uncommon command.
