When writing firmware for an embedded system, immunity-aware programming refers to programming techniques which improve the tolerance of transient errors in the program counter or other modules of a program that would otherwise lead to failure. Transient errors are typically caused by single event upsets, insufficient power, or by strong electromagnetic signals transmitted by some other "source" device.

Immunity-aware programming is an example of defensive programming and EMC-aware programming. Although most of these techniques apply to the software in the "victim" device to make it more reliable, a few of these techniques apply to software in the "source" device to make it emit less unwanted noise.

Vibe coding, sometimes spelled as vibecoding, is an AI-powered programming practice where you surrender to the "vibes" and power of the AI, while ignoring the details of the generated code. After describing a problem in a few sentences, you watch as the AI codes a custom solution such as an app or website. Vibe coding may feel like sorcery. Amateur programmers can now produce software, with limited features and sometimes imperfectly, that previously would have needed a software team. The practice defies the belief in the software industry that software engineering demands great skill.

SETL (SET Language) is a very high-level programming language based on the mathematical theory of sets. It was originally developed at the New York University (NYU) Courant Institute of Mathematical Sciences in the late 1960s, by a group including (Jack) Jacob T. Schwartz, R.B.K. Dewar, and E. Schonberg. Schwartz is credited with designing the language.

“Where do you want to go today?” was the title of Microsoft’s second global image advertising campaign. The broadcast, print and outdoor advertising campaign was launched in November 1994 through the advertising agency Wieden+Kennedy. The campaign had Microsoft spending $100 million through July 1995, of which $25 million would be spent during the holiday shopping season ending in December 1994.

Tony Kaye directed a series of television ads filmed in Hong Kong, Prague and New York City that showed a broad range of people using their PCs. The television ads were first broadcast in Australia on November 13, the following day in both the United States and Canada, with Britain, France and Germany seeing the spots in subsequent days. An eight-page print ad described the personal computer as “an open opportunity for everybody” that “[facilitates] the flow of information so that good ideas—wherever they come from—can be shared”, and was placed in mass-market magazines including National Geographic, Newsweek, People, Rolling Stone and Sports Illustrated.

The New York Times described the campaign as taking “a winsome, humanistic approach to demystifying technology”. However, the Times reported in August 1995 that the response to Microsoft’s campaign in the advertising trade press had been “lukewarm” and quoted Brad Johnson of Advertising Age as stating that “Microsoft is on version 1.0 in advertising. Microsoft is not standing still. It will improve its advertising.” Microsoft’s Steve Ballmer, then the firm’s executive vice president, acknowledged that the response to the campaign had been “chilly”.

In June 1999, Microsoft announced that it would be ending its nearly five-year-long relationship with Wieden+Kennedy, shifting $100 million (~$166 million in 2022) in billings to McCann Erickson Worldwide Advertising in a split that was described by The New York Times as mutual. Dan Wieden, president and chief creative officer of the advertising agency, characterized the relationship with Microsoft as “intense” and said that it had “run its course”.

The Honeywell 316 was a popular 16-bit minicomputer built by Honeywell starting in 1969. It is part of the Series 16, which includes the Models 116 (1965, discrete^: 4), 316 (1969), 416 (1966), 516 (1966) and DDP-716 (1969). They were commonly used for data acquisition and control, remote message concentration, clinical laboratory systems, Remote Job Entry and time-sharing. The Series-16 computers are all based on the DDP-116 designed by Gardner Hendrie at Computer Control Company, Inc. (3C) in 1964.

The 516 and later the 316 were used as Interface Message Processors (IMP) for the American ARPANET and the British NPL Network.

ESP32 is a family of low-cost, energy-efficient microcontrollers that integrate both Wi-Fi and Bluetooth capabilities. These chips feature a variety of processing options, including the Tensilica Xtensa LX6 microprocessor available in both dual-core and single-core variants, the Xtensa LX7 dual-core processor, or a RISC-V microprocessor. In addition, the ESP32 incorporates components essential for wireless data communication such as built-in antenna switches, an RF balun, power amplifiers, low-noise receivers, filters, and power-management modules.

Typically, the ESP32 is embedded on device-specific printed circuit boards or offered as part of development kits that include a variety of GPIO pins and connectors, with configurations varying by model and manufacturer. The ESP32 was designed by Espressif Systems and is manufactured by TSMC using their 40 nm process. It is a successor to the ESP8266 microcontroller.

The productivity paradox refers to the slowdown in productivity growth in the United States in the 1970s and 1980s despite rapid development in the field of information technology (IT) over the same period. The term was coined by Erik Brynjolfsson in a 1993 paper ("The Productivity Paradox of IT") inspired by a quip by Nobel Laureate Robert Solow "You can see the computer age everywhere but in the productivity statistics." For this reason, it is also sometimes referred to as the Solow paradox.

The productivity paradox inspired many research efforts at explaining the slowdown, only for the paradox to disappear with renewed productivity growth in the developed countries in the 1990s. However, issues raised by those research efforts remain important in the study of productivity growth in general, and became important again when productivity growth slowed around the world again from the 2000s to the present day. Thus the term "productivity paradox" can also refer to the more general disconnect between powerful computer technologies and weak productivity growth.

Beerware is a somewhat tongue-in-cheek term for software released under a very relaxed license (beerware licensed software). It provides the end user with the right to use a particular program (or do anything else with the source code).

Bitcoin (₿) is a cryptocurrency. It is a decentralized digital currency without a central bank or single administrator that can be sent from user to user on the peer-to-peer bitcoin network without the need for intermediaries.

Transactions are verified by network nodes through cryptography and recorded in a public distributed ledger called a blockchain. Bitcoin was invented in 2008 by an unknown person or group of people using the name Satoshi Nakamoto and started in 2009 when its source code was released as open-source software. Bitcoins are created as a reward for a process known as mining. They can be exchanged for other currencies, products, and services. Research produced by University of Cambridge estimates that in 2017, there were 2.9 to 5.8 million unique users using a cryptocurrency wallet, most of them using bitcoin.

Bitcoin has been criticized for its use in illegal transactions, its high electricity consumption, price volatility, and thefts from exchanges. Some economists, including several Nobel laureates, have characterized it as a speculative bubble. Bitcoin has also been used as an investment, although several regulatory agencies have issued investor alerts about bitcoin.

GEOS (Graphic Environment Operating System) is a discontinued operating system from Berkeley Softworks (later GeoWorks). Originally designed for the Commodore 64 with its version being released in 1986, enhanced versions of GEOS later became available in 1987 for the Commodore 128 and in 1988 for the Apple II family of computers. A lesser-known version was also released for the Commodore Plus/4.

GEOS closely resembles early versions of the classic Mac OS and includes a graphical word processor (geoWrite) and paint program (geoPaint).

A December 1987 survey by the Commodore-dedicated magazine Compute!'s Gazette found that nearly half of respondents used GEOS. For many years, Commodore bundled GEOS with its redesigned and cost-reduced C64, the C64C. At its peak, GEOS was the third-most-popular microcomputer operating system in the world in terms of units shipped, trailing only MS-DOS and Mac OS (besides the original Commodore 64's KERNAL).

Other GEOS-compatible software packages were available from Berkeley Softworks or from third parties, including a reasonably sophisticated desktop publishing application called geoPublish and a spreadsheet called geoCalc. While geoPublish is not as sophisticated as Aldus Pagemaker and geoCalc not as sophisticated as Microsoft Excel, the packages provide reasonable functionality, and Berkeley Softworks founder Brian Dougherty claimed the company ran its business using its own software on Commodore 8-bit computers for several years.
