The GBU-39/B Small Diameter Bomb (SDB) is a 250 lb (110 kg) precision-guided glide bomb that is intended to provide aircraft with the ability to carry a higher number of more accurate bombs. Most US Air Force aircraft will be able to carry (using the BRU-61/A rack) a pack of four SDBs in place of a single 2,000 lb (907 kg) bomb.

The Small Diameter Bomb II (SDB II) / GBU-53/B, adds a tri-mode seeker (radar, infrared homing, and semiactive laser guidance) to the INS and GPS guidance of the original SDB.

In software engineering, a software development process is the process of dividing software development work into smaller, parallel or sequential steps or subprocesses to improve design, product management, and project management. It is also known as a software development life cycle (SDLC). The methodology may include the pre-definition of specific deliverables and artifacts that are created and completed by a project team to develop or maintain an application.

Most modern development processes can be vaguely described as agile. Other methodologies include waterfall, prototyping, iterative and incremental development, spiral development, rapid application development, and extreme programming.

A life-cycle "model" is sometimes considered a more general term for a category of methodologies and a software development "process" a more specific term to refer to a specific process chosen by a specific organization. For example, there are many specific software development processes that fit the spiral life-cycle model. The field is often considered a subset of the systems development life cycle.

The Strategic Defense Initiative (SDI), derisively nicknamed the "Star Wars program", was a proposed missile defense system intended to protect the United States from attack by ballistic strategic nuclear weapons (intercontinental ballistic missiles and submarine-launched ballistic missiles). The concept was announced on March 23, 1983 by President Ronald Reagan, a vocal critic of the doctrine of mutually assured destruction (MAD), which he described as a "suicide pact". Reagan called upon American scientists and engineers to develop a system that would render nuclear weapons obsolete.

The Strategic Defense Initiative Organization (SDIO) was set up in 1984 within the US Department of Defense to oversee development. A wide array of advanced weapon concepts, including lasers, particle beam weapons and ground- and space-based missile systems were studied, along with various sensor, command and control, and high-performance computer systems that would be needed to control a system consisting of hundreds of combat centers and satellites spanning the entire globe and involved in a very short battle. The United States holds a significant advantage in the field of comprehensive advanced missile defense systems through decades of extensive research and testing; a number of these concepts and obtained technologies and insights were transferred to subsequent programs.

Under the SDIO's Innovative Sciences and Technology Office, headed by physicist and engineer Dr. James Ionson, the investment was predominantly made in basic research at national laboratories, universities, and in industry; these programs have continued to be key sources of funding for top research scientists in the fields of high-energy physics, supercomputing/computation, advanced materials, and many other critical science and engineering disciplines and funding which indirectly supports other research work by top scientists.

In 1987, the American Physical Society concluded that the technologies being considered were decades away from being ready for use, and at least another decade of research was required to know whether such a system was even possible. After the publication of the APS report, SDI‘s budget was repeatedly cut. By the late 1980s, the effort had been re-focused on the "Brilliant Pebbles" concept using small orbiting missiles not unlike a conventional air-to-air missile, which was expected to be much less expensive to develop and deploy.

SDI was controversial in some sectors, and was criticized for threatening to destabilize the MAD-approach potentially rendering the Soviet nuclear arsenal useless and to possibly re-ignite "an offensive arms race". Through declassified papers of American intelligence agencies the wider implications and effects of the program were examined and revealed that due to the potential neutralization of its arsenal and resulting loss of a balancing power factor, SDI was a cause of grave concern for the Soviet Union and her primary successor state Russia. By the early 1990s, with the Cold War ending and nuclear arsenals being rapidly reduced, political support for SDI collapsed. SDI officially ended in 1993, when the Clinton Administration redirected the efforts towards theatre ballistic missiles and renamed the agency the Ballistic Missile Defense Organization (BMDO).

Senior Officer Present Afloat, usually referred to as SOPA, is a U.S. Navy term to indicate the U.S. Navy officer, with the highest ranking by rank, or number in rank, present in a harbor occupied by more than one U.S. Navy vessel. That officer is essentially commander of all U.S. Navy operations afloat in the harbor and is responsible to civilian authorities for the action of the ships and the behavior of crews under his or her command.

SOPA is a useful administrative function in foreign ports visited by U.S. Navy vessels. However, SOPA may also be established in continental U.S. ports.

The Office of Tailored Access Operations (TAO), now Computer Network Operations, structured as S32 is a cyber-warfare intelligence-gathering unit of the National Security Agency (NSA). It has been active since at least 1998, possibly 1997, but was not named or structured as TAO until "the last days of 2000," according to General Michael Hayden.

TAO identifies, monitors, infiltrates, and gathers intelligence on computer systems being used by entities foreign to the United States.

Anarchism is a political philosophy and movement that is sceptical of authority and rejects all involuntary, coercive forms of hierarchy. Anarchism calls for the abolition of the state, which it holds to be undesirable, unnecessary, and harmful. As a historically left-wing movement, placed on the farthest left of the political spectrum, it is usually described alongside libertarian Marxism as the libertarian wing (libertarian socialism) of the socialist movement, and has a strong historical association with anti-capitalism and socialism.

The history of anarchism goes back to prehistory, when humans lived in anarchic societies long before the establishment of formal states, realms, or empires. With the rise of organised hierarchical bodies, scepticism toward authority also rose, but it was not until the 19th century that a self-conscious political movement emerged. During the latter half of the 19th and the first decades of the 20th century, the anarchist movement flourished in most parts of the world and had a significant role in workers' struggles for emancipation. Various anarchist schools of thought formed during this period. Anarchists have taken part in several revolutions, most notably in the Spanish Civil War, whose end marked the end of the classical era of anarchism. In the last decades of the 20th and into the 21st century, the anarchist movement has been resurgent once more.

Anarchism employs a diversity of tactics in order to meet its ideal ends which can be broadly separated into revolutionary and evolutionary tactics; there is significant overlap between the two, which are merely descriptive. Revolutionary tactics aim to bring down authority and state, having taken a violent turn in the past, while evolutionary tactics aim to prefigure what an anarchist society would be like. Anarchist thought, criticism, and praxis have played a part in diverse areas of human society. Anarchism has been both defended and criticised; criticism of anarchism include claims that it is internally inconsistent, violent, or utopian.
