Finder
The Finder is the default file manager and graphical user interface shell used on all Macintosh operating systems. Described in its "About" window as "The Macintosh Desktop Experience", it is responsible for the launching of other applications, and for the overall user management of files, disks, and network volumes. It was introduced with the first Macintosh computer, and also exists as part of GS/OS on the Apple IIGS. It was rewritten completely with the release of Mac OS X in 2001. In a tradition dating back to the Classic Mac OS of the 1980s and 1990s, the Finder icon is the smiling screen of a computer, known as the Happy Mac logo.

Navigation Systems for the Visually Impaired
The visually impaired suffer greatly while moving from one place to another. They face challenges in going outdoors and in protecting themselves from moving and stationary objects, and they also lack confidence due to restricted mobility. Due to the recent rapid rise in the number of visually impaired persons, the development of assistive devices has emerged as a significant research field.

IBM Integration Bus
IBM APP Connect Enterprise (abbreviated as IBM ACE, formerly known as IBM Integration Bus or WebSphere Message Broker) is IBM's integration broker from the WebSphere product family that allows business information to flow between disparate applications across multiple hardware and software platforms. Rules can be applied to the data flowing through the message broker to route and transform the information. The product is an Enterprise Service Bus supplying a communication channel between applications and services in a service-oriented architecture. IBM ACE provides capabilities to build solutions needed to support diverse integration requirements through a set of connectors to a range of data sources, including packaged applications, files, mobile devices, messaging systems, and databases. A benefit of using IBM ACE is that the tool enables existing applications for Web Services without costly legacy application rewrites. ACE avoids the point-to-point strain on development resources by connecting any application or service over multiple protocols, including SOAP, HTTP and JMS. Modern secure authentication mechanisms, including the ability to perform actions on behalf of masquerading or delegate users, through MQ, HTTP and SOAP nodes are supported such as LDAP, X-AUTH, O-AUTH, and two-way SSL. A major focus of IBM ACE in its latest release is the capability of the product's runtime to be fully hosted in a cloud. Hosting the runtime in the cloud provides certain advantages and potential cost savings compared to hosting the runtime on premises as it simplifies the maintenance and application of OS-level patches which can sometimes be disruptive to business continuity. Also, cloud hosting of IBM ACE runtime allows easy expansion of capacity by adding more horsepower to the CPU configuration of a cloud environment or by adding additional nodes in an Active-Active configuration. Another advantage of maintaining ACE runtimes in the cloud is the ability to configure access to your ACE functionality separate and apart from your internal network using DataPower or API Connect devices. This allows people or services on the public internet to access your Enterprise Service Bus without passing through your internal network, which can be a more secure configuration than if your ESB was deployed to your internal on premises network. IBM ACE embeds a Common Language Runtime to invoke any .NET logic as part of an integration. It also includes full support for the Visual Studio development environment, including the integrated debugger and code templates. IBM Integration Bus includes a comprehensive set of patterns and samples that demonstrate bi-directional connectivity with both Microsoft Dynamics CRM and MSMQ. Several improvements have been made to this current release, among them the ability to configure runtime parameters using a property file that is part of the deployed artifacts contained in the BAR ('broker archive') file. Previously, the only way to configure runtime parameters was to run an MQSI command on the command line. This new way of configuration is referred to as a policy document and can be created with the new Policy Editor. Policy documents can be stored in a source code control system and a different policy can exist for different environments (DEV, INT, QA, PROD). IBM ACE is compatible with several virtualization platforms right out-of-the-box, Docker being a prime example. With ACE, you can download from the global Docker repository a runtime of IBM ACE and run it locally. Because ACE has its administrative console built right into the runtime, once the Docker image is active on your local, you can do all the configuration and administration commands needed to fully activate any message flow or deploy any BAR file. In fact, you can construct message flows that are microservices and package these microservices into a Docker deployable object directly. Because message flows and BAR files can contain Policy files, this node configuration can be automatic and no or little human intervention is needed to complete the application deployment.

Enchanta
Enchanta /ɛnˈtʃɑːntɑː/ (Enchan /ɛnˈtʃɑːn/ in the 2016 series) is a constructed language spoken by the denizens of Encantadia, known as Encantado(s)/Encantada(s) or Diwata (fairies). It was initially created by Suzette Doctolero for the Philippines fantasy television drama saga Encantadia, which aired on GMA Network in 2005, and was later used in the show's sequels, Etheria: Ang Ikalimang Kaharian ng Encantadia and Encantadia: Pag-ibig Hanggang Wakas. The source material of the language appears to have been derived from Philippine languages (particularly Tagalog) and Romance languages. It has its own script, Enchan, which appears to be based on Baybayin. Three songs in the language are written by Doctolero, namely "Asshenti (Love song)", "Hade!! (Etheria theme song)", and "Ivo (Lireo national anthem)", which are all sung by Bayang Barrios for the sequel Etheria in 2006.

Benchmarking the Performance of a Quantum Computer
The quantum computer has been claimed to show more quantum advantage than the classical computer in solving some specific problems. Many companies and research institutes try to develop quantum computers with different physical implementations. Currently, most people only focus on the number of qubits in a quantum computer and consider it as a standard to evaluate the performance of the quantum computer intuitively. However, it is quite misleading in most times, especially for investors or governments. This is because the quantum computer works in a quite different way than classical computers. Thus, quantum benchmarking is of great importance. Currently, many quantum benchmarks are proposed from different aspects.

Cache Placement Policies
Cache is a memory which holds the recently utilized data by the processor. A block of memory cannot be placed randomly in the cache and is restricted to a single cache line by the “Placement Policy”. In other words, Placement Policy determines where a particular memory block can be placed when it goes into the cache. There are three different policies available for placement of a memory block in the cache.

Colord
Linux color management has the same goal as the color management systems (CMS) for other operating systems: to achieve the best possible color reproduction throughout an imaging workflow from its source (camera, video, scanner, etc.), through imaging software (Digikam, darktable, RawTherapee, GIMP, Krita, Scribus, etc.), and finally onto an output medium (monitor, video projector, printer, etc.). In particular, color management attempts to enable color consistency across media and throughout a color-managed workflow. Linux color management relies on the use of accurate ICC (International Color Consortium) and DCP (DNG Color Profile) profiles describing the behavior of input and output devices, and color-managed applications that are aware of these profiles. These applications perform gamut conversions between device profiles and color spaces. Gamut conversions, based on accurate device profiles, are the essence of color management. Historically, color management was not an initial design consideration of the X Window System on which much of Linux graphics support rests, and thus color-managed workflows have been somewhat more challenging to implement on Linux than on other OS's such as Microsoft Windows or macOS. This situation is now being progressively remedied, and color management under Linux, while functional, has not yet acquired mature status. Although it is now possible to obtain a consistent color-managed workflow under Linux, certain problems still remain: Since ICC color profiles are written to an open specification, they are compatible across operating systems. Hence, a profile produced on one OS should work on any other OS given the availability of the necessary software to read it and perform the gamut conversions. This can be used as a workaround for the lack of support for certain spectrophotometers or colorimeters under Linux: one can simply produce a profile on a different OS and then use it in a Linux workflow. Additionally, certain hardware, such as most printers and certain monitors, can be calibrated under another OS and then used in a fully color-managed workflow on Linux. The popular Ubuntu Linux distribution added initial color management in the 11.10 release (the "Oneiric Ocelot" release).

Epileptic seizures and deep learning
Chronic diseases are growing exponentially. Today, there are over 900 million individuals suffering with some chronic diseases around the world. For this reason, e-health systems are being developed to design a better quality of life for patients. For instance, we have systems for detection of epilepsy, monitoring of vital signs, control of diabetes, among others. Deep learning has being an important technique embedded in these systems to predict and sort the data without the need of a 24-hour monitoring specialist. However, by combining e-health systems and deep learning techniques also brings several challenges that need to be overcome.

Mozilla Public License
The Mozilla Public License (MPL) is a free and open-source weak copyleft license for most Mozilla Foundation software such as Firefox and Thunderbird The MPL license is developed and maintained by Mozilla, which seeks to balance the concerns of both open-source and proprietary developers; it is distinguished from others as a middle ground between the permissive software BSD-style licenses and the General Public License. So under the terms of the MPL, it allows the integration of MPL-licensed code into proprietary codebases, but only on condition those components remain accessible. MPL has been used by others, such as Adobe to license their Flex product line, and The Document Foundation to license LibreOffice 4.0 (also on LGPL 3+). Version 1.1 was adapted by several projects to form derivative licenses like Sun Microsystems' Common Development and Distribution License. It has undergone two revisions: the minor update 1.1, and a major update version 2.0 nearing the goals of greater simplicity and better compatibility with other licenses.
