Tehachapi Energy Storage Project
The Tehachapi Energy Storage Project (TSP) is a lithium-ion battery-based grid energy storage system at the Monolith Substation of Southern California Edison (SCE) in Tehachapi, California. At the time of commissioning in 2014, it was the largest lithium-ion battery system operating in North America and one of the largest in the world. The TSP system can supply 32 megawatt-hours of energy, at a maximum rate of 8 megawatts. This is sufficient to power between 1,600 and 2,400 homes for four hours. TSP is considered to be a modern-day energy storage pioneer with significant accomplishments that have proven the viability of utility-scale energy storage using lithium-ion technology. While originally envisioned as a research and development project, TSP continues operation today as a distribution-level resource for SCE and for calendar year 2020, SCE reported that TSP operated in the wholesale energy market with revenue exceeding operating and maintenance costs.

Best Coding Practices
Coding best practices are a set of informal rules that the software development community employ to help improve the quality of software. Many computer programs remain in use for long periods of time, so any rules need to facilitate both initial development and subsequent maintenance and enhancement by people other than the original authors. In Ninety-ninety rule, Tom Cargill is credited with an explanation as to why programming projects often run late: "The first 90% of the code accounts for the first 90% of the development time. The remaining 10% of the code accounts for the other 90% of the development time." Any guidance which can redress this lack of foresight is worth considering. The size of a project or program has a significant effect on error rates, programmer productivity, and the amount of management needed.

Also, despite its title, Alundra 2 is a standalone sequel, and has no ties with the original. It has a whole new story with a different set of characters, including the main character, Flint. Compared to the darker storyline of Alundra, Alundra 2 has a more light-hearted storyline.

Bullet Journal
Bullet Journal is a method of personal organization developed by designer Ryder Carroll. The system organizes scheduling, reminders, to-do lists, brainstorming, and other organizational tasks into a single notebook. The name "Bullet Journal" comes from the use of abbreviated bullet points to log information, but it also partially comes from the use of dot journals, which are gridded using dots rather than lines. First shared with the public in 2013, it has become a popular method, garnering significant attention on Kickstarter, Instagram, Facebook, YouTube, and Pinterest.

Soling
The Soling is an International open keelboat class designed by Jan Linge from Norway in 1965. In 1968, it was selected to be an Olympic class for the Games of the XX Olympiad in Kiel 1972 (GER). The Soling maintained this status until her final appearance at the 2000 Olympics. The Soling is a strong boat designed for any wind and sea condition. The boats are one-design originating from an authorized single plug and mould and made of glass reinforced polyester, making competition as equal as possible. The lifetime of a Soling is long. Those produced in the early days are still in competition (more than 50 years after being built). At the 2019 North American Championship the 5th place was taken by a German team (GER 1) sailing a refurbished Soling build in 1968. Characteristic for the Soling is the droop-hiking technique. Since 2008, the Soling is one of the Vintage Yachting Classes at the Vintage Yachting Games.

Phosphorus (Morning Star)
Phosphorus (Greek Φωσφόρος Phōsphoros) is the Morning Star, the planet Venus in its morning appearance. Φαοσφόρος (Phaosphoros) and Φαεσφόρος (Phaesphoros) are forms of the same name in some Greek dialects. This celestial object was named when stars and planets were not always distinguished with modern precision. Another Greek name for the Morning Star is Heosphoros (Greek Ἑωσφόρος Heōsphoros), meaning "Dawn-Bringer". The form Eosphorus is sometimes met in English, as if from Ἠωσφόρος (Ēōsphoros), which is not actually found in Greek literature, but would be the form that Ἑωσφόρος would have in some dialects. As an adjective, the Greek word φωσφόρος is applied in the sense of "light-bringing" to, for instance, the dawn, the god Dionysos, pine torches, the day; and in the sense of "torch-bearing" as an epithet of several god and goddesses, especially Hecate but also of Artemis/Diana and Hephaestus. The Latin word lucifer, corresponding to Greek φωσφόρος, was used as a name for the morning star and thus appeared in the Vulgate translation of the Hebrew word הֵילֵל (helel), meaning Venus as the brilliant, bright or shining one, in Isaiah 14:12, where the Septuagint Greek version uses, not φωσφόρος, but ἑωσφόρος. As a translation of the same Hebrew word the King James Version gave "Lucifer", a name often misunderstood as a reference to Satan. Modern translations of the same passage render the Hebrew word instead as "morning star", "daystar", "shining one" or "shining star". In Revelation 22:16, Jesus is referred to as the morning star, but not as lucifer in Latin, nor as φωσφόρος in the original Greek text, which instead has ὁ ἀστὴρ ὁ λαμπρὸς ὁ πρωϊνός (ho astēr ho lampros ho prōinos), literally: the star, the shining one, the dawn. In the Vulgate Latin text of 2 Peter 1:19 the word "lucifer" is used of the morning star in the phrase "until the day dawns and the morning star rises in your hearts", the corresponding Greek word being φωσφόρος.

Facebook Messenger Rooms
Facebook Messenger (also known as Messenger) is an American messaging app and platform developed by Facebook, Inc. Originally developed as Facebook Chat in 2008, the company revamped its messaging service in 2010, and subsequently released standalone iOS and Android apps in August 2011 and standalone Facebook Portal hardware for Messenger-based calling in Q4 2018. Later on, Facebook has launched a dedicated website interface (Messenger.com), and separated the messaging functionality from the main Facebook app, allowing users to use the web interface or download one of the standalone apps. In April 2020, Facebook officially released Messenger for Desktop, which is supported on Windows 10 and macOS and distributed on Microsoft Store and App Store respectively. Users can send messages and exchange photos, videos, stickers, audio, and files, as well as react to other users' messages and interact with bots. The service also supports voice and video calling. The standalone apps support using multiple accounts, conversations with optional end-to-end encryption, and playing games.
