Health Service Executive Ransomware Attack
On 14 May 2021, the Health Service Executive (HSE) of Ireland suffered a major ransomware cyberattack which caused all of its IT systems nationwide to be shut down. It was the most significant cybercrime attack on an Irish state agency and the largest known attack against a health service computer system. Bloomberg News reported that the attackers used the Conti ransomware. The group responsible was identified as a criminal gang known as Wizard Spider, believed to be operating from Russia. The same group is believed to have attacked the Department of Health with a similar cyberattack. On 19 May, the Financial Times reviewed private data for twelve individuals which had appeared online as a result of the breach. On 28 May, the HSE confirmed confidential medical information for 520 patients, as well as corporate documents were published online. On 23 June, it was confirmed that at least three quarters of the HSE's IT servers had been decrypted and 70% of computer devices were back in use. By September, over 95% of all servers and devices had been restored.

Haskell (Programming Language)
Haskell (/ˈhæskəl/) is a general-purpose, statically-typed, purely functional programming language with type inference and lazy evaluation. Designed for teaching, research and industrial application, Haskell has pioneered a number of programming language features such as type classes, which enable type-safe operator overloading. Haskell's main implementation is the Glasgow Haskell Compiler (GHC). It is named after logician Haskell Curry. Haskell's semantics are historically based on those of the Miranda programming language, which served to focus the efforts of the initial Haskell working group. The last formal specification of the language was made in July 2010, while the development of GHC has expanded Haskell via language extensions. The next formal specification (As of 2020). On 29 October 2021 GHC2021 was released in GHC version 9.2.1. Haskell is used in academia and industry. (As of May 2021), Haskell was the 28th most popular programming language by Google searches for tutorials, and made up less than 1% of active users on the GitHub source code repository.

ACT-R
ACT-R (pronounced /ˌækt ˈɑr/; short for "Adaptive Control of Thought—Rational") is a cognitive architecture mainly developed by John Robert Anderson and Christian Lebiere at Carnegie Mellon University. Like any cognitive architecture, ACT-R aims to define the basic and irreducible cognitive and perceptual operations that enable the human mind. In theory, each task that humans can perform should consist of a series of these discrete operations. Most of the ACT-R's basic assumptions are also inspired by the progress of cognitive neuroscience, and ACT-R can be seen and described as a way of specifying how the brain itself is organized in a way that enables individual processing modules to produce cognition.

Lieb–Oxford Inequality
In quantum chemistry and physics, the Lieb–Oxford inequality provides a lower bound for the indirect part of the Coulomb energy of a quantum mechanical system. It is named after Elliott H. Lieb and Stephen Oxford. The inequality is of importance for density functional theory and plays a role in the proof of stability of matter.

HP QuickTest Professional
HPE Unified Functional Testing (UFT) software, formerly known as HP QuickTest Professional (QTP), provides functional and regression test automation for software applications and environments. HPE Unified Functional Testing can be used for enterprise quality assurance. HPE Unified Functional Testing supports keyword and scripting interfaces and features a graphical user interface. It uses the Visual Basic Scripting Edition (VBScript) scripting language to specify a test procedure, and to manipulate the objects and controls of the application under test. HPE Unified Functional Testing was originally written by Mercury Interactive and called QuickTest Professional. Mercury Interactive was subsequently acquired by Hewlett Packard(HP) in 2006. HP Unified Functional Testing 11.5 combined HP QuickTest Professional and HP Service Test into a single software package, which was available from the HP Software Division until 2016, when whole division was sold to Micro Focus. The integrated HPE Unified Functional Testing software allows developers to test from a single console all three layers of a program's operations: the interface, the service layer and the database layer.
