In projects in which the actor of the system is another system or a software agent, it is quite possible that there is no end-user for the system.

Free and open source software libraries have been created to support such features in a portable way, and are most notably found in the repositories of the Common-Lisp. net and Common Lisp Open Code Collection projects.

Examples of this would be woodworking, photography, moviemaking, jewelry making, software projects such as Photoshopping and home music or video production, making bracelets, artistic projects ( such as drawing, painting, etc.

This is because free and open source software allows hackers to get access to the source code used to create the software, to allow it to be improved or reused in other projects.

It is also developing software projects, IT systems for the future martian habitat, with a Virtual Mars Base and remote access.

The software libraries may include software tools to adjust resolution, screen colors, pointers and screenmodes.

Other software may use alpha blended transparent elements in the GUI independently of OS provided APIs by precomposing elements in an off-screen memory buffer before displaying them.

Whilst it may not have been as popular as the Spectrum, Commodore 64 or Amstrad CPC, it did sell in sufficient numbers to ensure that new software was being produced right up until the early 1990s.

They may also be in the user interface of the software or on a screen presented to the user during the installation process.

Adware, by itself, is harmless ; however, some adware may come with integrated spyware such as keyloggers and other privacy-invasive software .< ref name =" McAfee-def ">

In systems engineering it may involve black-box testing performed on a system ( for example: a piece of software, lots of manufactured mechanical parts, or batches of chemical products ) prior to its delivery.

Booting is a chain of events that starts with execution of hardware-based procedures and may then hand-off to firmware and software which is loaded into main memory.

If a newer software version cannot save files that can be read by the older version, it is not backward compatible with the older version, although it may provide an irreversible upgrade capability for the old files.

Trade deficits generated in tradeable goods such as manufactured goods or software may impact domestic employment to different degrees than trade deficits in raw materials.

Apps may be bundled with the computer and its system software, or may be published separately.

Depending on how competently the user-written software has been integrated into default application packages, many users may not be aware of the distinction between the original packages, and what has been added by co-workers.

The controversy over software patents is about specific algorithms or techniques that the software contains, which may not be duplicated by others and considered intellectual property and copyright infringement depending on the severity.

A paralegal or court officer may keep track of the cases by using docketing software.

Computer programs may be categorized along functional lines: system software and application software.

Tom McPhail defined " Electronic colonialism as the dependency relationship established by the importation of communication hardware, foreign-produced software, along with engineers, technicians, and related information protocols, that vicariously establish a set of foreign norms, values, and expectations which, in varying degrees, may alter the domestic cultures and socialization processes.

Many rendering algorithms have been researched, and software used for rendering may employ a number of different techniques to obtain a final image.

The handler may save additional context, depending on details of the particular hardware and software designs.

Additional research notes that test users may be able to identify an area that proves challenging in a software system, but might have difficulty explaining the outcome.

Some content-control software includes time control functions that empowers parents to set the amount of time that child may spend accessing the Internet or playing games or other computer activities.

Internet filters, parental control software, and / or accountability software may also be combined into one product.

For general computer use access technology such as screen readers, screen magnifiers and refreshable Braille displays has been widely taken up along with standalone reading aids that integrate a scanner, optical character recognition ( OCR ) software, and speech software in a single machine.

) Compositing software is used to combine images, and makes extensive use of alpha compositing techniques.

Although cheap and effective in enabling use of some software that only used official ROM entry points for text output, this solution proved very slow because the Electron had to be placed into an 80-byte-pitch display to be able to get anywhere near to reproducing mode 7 and the CPU spent a lot of time drawing approximations of mode 7 characters and graphics that in a hardware solution would be achieved without any CPU processing.

These included updates to EtherTalk and TokenTalk, AppleTalk software and LocalTalk hardware for the IBM PC, EtherTalk for Apple's A / UX operating system allowing it to use LaserPrinters and other network resources, and the Mac X. 25 and MacX products.

The Aster computer could use the software written for the popular Tandy TRS-80 computer while fixing many of the problems of that computer, but it could also run CP / M software, with a big amount of free memory ( Transient Program Area, TPA ) and a full 80 × 25 display, and it could be used as a Videotext terminal.

In order to use AIM Phoneline users must download the latest version of an AIM Triton software ( the free one ), and must have a good set of headphones that has a microphone attached.

While some software developers use the term ISO C, others are standards body – neutral and use Standard C.

If the software works as intended and without issues during normal use, one can reasonably extrapolate the same level of stability in production.

The software and computer industries often use binary approximations of the SI-prefixed quantities, while producers of computer storage devices prefer the SI values.

In the UK, the BBC Micro based OBBS software, available from Pace for use with their modems, optionally allowed for colour and graphics using the Teletext based graphics mode available on that platform.

For those more nostalgic for the true BBS experience, one can use NetSerial ( Windows ) or DOSBox ( Windows /* nix ) to redirect DOS COM port software to telnet, allowing them to connect to Telnet BBSes using 1980s and 1990s era modem terminal emulation software, like Telix, Terminate, Qmodem and Procomm Plus.

A notable example was Phil Katz's PKARC ( and later PKZIP, using the same ". zip " algorithm that WinZip and other popular archivers now use ); also other concepts of software distribution like freeware, postcardware like JPEGview and donationware like Red Ryder for the Macintosh first appeared on BBS sites.

At the time, nearly all use of computers required writing custom software, which was something only scientists and mathematicians tended to do.

The presence of an easy-to-learn language such as BASIC on these early personal computers allowed small business owners to develop their own custom application software, leading to widespread use of these computers in businesses that previously did not have access to computing technology.

The code quality and general utility along with the licensing terms have led to its use in a multitude of free and open source software.

Notable software that use Berkeley DB for data storage include:

Software that is not distributed can use the Sleepycat License, as can free and open source software.

Proprietary software can use Berkeley DB only under a commercial license agreement between Oracle and the application's publisher.

* Computer-assisted reviewing, the use of computer software for more effective text reviewing
