Gecko
Gecko is a browser engine developed by Mozilla. It is used in the Firefox browser, the Thunderbird email client, and many other projects. Gecko is designed to support open Internet standards, and is used by different applications to display web pages and, in some cases, an application's user interface itself (by rendering XUL). Gecko offers a rich programming API that makes it suitable for a wide variety of roles in Internet-enabled applications, such as web browsers, content presentation, and client/server. Gecko is written in C++ and JavaScript, and, since 2016, additionally in Rust. It is free and open-source software subject to the terms of the Mozilla Public License version 2. Mozilla officially supports its use on Android, Linux, macOS, and Windows.

Aperiodic Frequency
Frequency is the number of occurrences of a repeating event per unit of time. It is also referred to as temporal frequency, which emphasizes the contrast to spatial frequency and angular frequency. Frequency is measured in units of hertz (Hz) which is equal to one occurrence of a repeating event per second. The period is the duration of time of one cycle in a repeating event, so the period is the reciprocal of the frequency. For example: if a newborn baby's heart beats at a frequency of 120 times a minute (2 hertz), its period, T, — the time interval between beats—is half a second (60 seconds divided by 120 beats). Frequency is an important parameter used in science and engineering to specify the rate of oscillatory and vibratory phenomena, such as mechanical vibrations, audio signals (sound), radio waves, and light.

Comparison of Mail Servers
This is a comparison of mail servers: mail transfer agents, mail delivery agents, and other computer software that provide e-mail services. Unix based mail servers are built using a number of components because a Unix style environment is, by default, a toolbox operating system. A stock Unix-like server already has internal mail, more traditional ones also come with a full MTA already part of the standard installation. To allow the server to send external emails, an MTA such as Sendmail, Postfix, or Exim is required. Mail is read either through direct access (shell login) or mailbox protocols like POP and IMAP. Unix based MTA software largely acts as enhancement or replacement of the respective system's "native" MTA. Windows servers do not natively implement email. Windows based MTAs therefore have to cover the whole set of email related functionality.

Distributed Agile Software Development
Distributed Agile Software Development is a research area that considers the effects of applying the principles of Agile software development to software development in a globally distributed development setting. The goal of applying these principles is overcoming challenges in projects which are geographically distributed. The principles of Agile software development provide structures to promote better communication, which is an important factor in successfully working in a distributed setting. However, not having face-to-face interaction takes away one of the core principles of Agile. This makes Distributed Agile Software Development more challenging than Agile Software Development in general.

Google Data Centers
Google Data Centers are the large data center facilities Google uses to provide their services, which combine large drives, computer nodes organized in aisles of racks, internal and external networking, environmental controls (mainly cooling and dehumidification), and operations software (especially as concerns load balancing and fault tolerance). There is no official data on how many servers are in Google data centers, but Gartner estimated in a July 2016 report that Google at the time had 2.5 million servers. This number is changing as the company expands capacity and refreshes its hardware.

GLIMMER
In bioinformatics, GLIMMER (Gene Locator and Interpolated Markov ModelER) is used to find genes in prokaryotic DNA. "It is effective at finding genes in bacteria, archea, viruses, typically finding 98-99% of all relatively long protein coding genes". GLIMMER was the first system that used the interpolated Markov model to identify coding regions. The GLIMMER software is open source and is maintained by Steven Salzberg, Art Delcher, and their colleagues at the Center for Computational Biology at Johns Hopkins University. The original GLIMMER algorithms and software were designed by Art Delcher, Simon Kasif and Steven Salzberg and applied to bacterial genome annotation in collaboration with Owen White.

Octopussy
Octopussy, also known as 8Pussy, is a free and open-source computer-software which monitors systems, by constantly analyzing the syslog data they generate and transmit to such a central Octopussy server (thus often called a SIEM solution). Therefore, software like Octopussy plays an important role in maintaining an information security management system within ISO/IEC 27001-compliant environments. Octopussy has the ability to monitor any device that supports the syslog protocol, such as servers, routers, switches, firewalls, load balancers, and its important applications and services. The main purpose of the software is to alert its administrators and users to different kinds of events, like system outages, attacks on systems or errors in applications. However, unlike Nagios or Icinga, Octopussy is not a state-checker and therefore problems cannot be resolved within the application. The software also makes no prescription whatsoever on which messages must be/must not be analyzed. As such, Octopussy can be seen as less powerful than other popular commercial software in the same category (event monitoring and log analysis). Octopussy is compatible with many Linux system distributions like Debian, Ubuntu, OpenSUSE, CentOS, RHEL and even meta-distributions as Gentoo or Arch Linux. Although Octopussy was originally designed to run on Linux, it could be ported to other Unix variants like FreeBSD with minimal effort. Octopussy has extensive report generating features and also various interfaces to other software, like e.g. NSCA (Nagios), Jabber/XMPP and Zabbix. With the help of software like Snare even Windows EventLogs can be processed. Octopussy is licensed under the terms of the GNU General Public License.

Future Proof
Future-proofing is the process of anticipating the future and developing methods of minimizing the effects of shocks and stresses of future events. Future-proofing is used in industries such as electronics, medical industry, industrial design, and more recently, in design for climate change. The principles of future-proofing are extracted from other industries and codified as a system for approaching an intervention in an historic building.

Moho (Anime Studio)
Moho is a proprietary vector-based 2D animation software distributed by Smith Micro Software. Moho, (formerly known as Anime Studio), was originally distributed by LostMarble, and then by e frontier. Smith Micro Software has distributed Anime Studio since November 2007. The software comes in two different versions, Moho Debut and Moho Pro. The first being restricted in terms of length and image size, as well as not containing all of the functions of the Pro version. Anime Studio is available for Windows and Macintosh operating systems in English, German, Japanese and Spanish (Since version 9.2). Moho Pro no longer supports the Linux platform.
