The Evil Within is a 2017 American horror film written and directed by Andrew Getty.
 Originally titled The Storyteller, the film was a personal project of Getty, who largely self-financed the estimated cost of four to six million dollars of the production that took 15 years to complete.
 It was released in 2017, two years after Getty's death in 2015.
Seña wine was established as a collaborative venture in Chile between Viña Errázuriz and Robert Mondavi .
 Since 2005 Seña is owned 100% by the Chadwick family, proprietors of Errázuriz, and is the personal project of Eduardo Chadwick.
 Eduardo's ambition is to create a Chilean icon wine, one which fully expresses the terroir (wine identity linked to local soil, aspect and climate) of the Aconcagua Valley north of Santiago.
 The inaugural vintage of Seña, which is Spanish for distinguishing mark or personal signature, was that of 1995.
 The wine is made from a blend of six of the classic red grape varietals: Cabernet Sauvignon, Merlot, Carmenère, Cabernet Franc, Petit Verdot and Malbec.
 The grapes for Seña are sourced from Seña Hillside vineyards within the Aconcagua Valley, in which vines are grown according to bio-dynamic principles.
 The wine is currently produced at Errázuriz's Don Maximiano Estate winery in the Aconcagua Valley.
Fission is a Swedish melodic death metal band formed in 2002.
 The band began as Benny Hägglund's personal project, with the hopes of fusing melody and aggression into his music.
 After writing some material, he decided to seek aid from Andreas Hedlund of Vintersorg, the band in which Hägglund plays live session drums.
 After recording a two-track demo with Benny handling all instrumentation and Andreas handling vocal duties, they signed on with Austrian label, Napalm Records.
 Benny continued writing all of the songs for their first full-length, while Andreas provided all of the lyrics, vocals, keyboards, and sound effects.
 They released their first full-length album, "Crater", on April 27, 2004.
Życie po śmierci (] , English: "Life After Death"), stylized as Życie po śmierci) is an album by Polish hip-hop rapper and producer O.S.T.R., released on February 26, 2016 on Asfalt Records.
 O.S.T.R. said that the main factor that made him record "Życie po śmierci" was his disease he had had at the beginning of 2015.
 He had had to have his lung removed, due to the fact that he had been smoking for most of his life.
 He also claimed that this album is the most personal project he had ever recorded.
 The main inspiration for the title of the album was the Notorious B.I.G.'s 1997 project "Life After Death".
 A special website was created to promote the album.
 On the website O.S.T.R. left a letter written to his fans, when he recalls a story of his disease and informs that "Życie po śmierci" is going to be a soundtrack for a "book or rap musical".
Project Darkstar was an open source MMOG middleware solution written in Java.
 Project Darkstar began as a personal project of Jeff Kesselman in 1999.
 It later became a research project at Sun Microsystems, and aimed to "help developers and operators avoid a range of serious, yet typical, problems associated with massive scale online games, virtual worlds, and social networking applications today, including zone overloading, data corruption, and server underutilization."
Journler is an open-source hybrid diary and personal information manager for Macintosh.
 It features a three-pane interface and supports tagging and categorizing of entries.
 The entries can be rich text, but also can contain images, PDFs, and other media that OS X supports.
 It is oriented toward chronological organization of entries, as in a diary or journal, and has a built-in calendar.
 Later versions aimed to be a flexible tool for personal project management and for fans of the Getting Things Done system.
The history of Linux began in 1991 with the commencement of a personal project by Finnish student Linus Torvalds to create a new free operating system kernel.
The LEAF - Linux Embedded Appliance Framework (Linux Embedded Appliance Framework) is a collection of Linux distributions that began as a fork from the Linux Router Project (LRP) "linux-on-a-floppy" distribution.
 Most users of these distributions are primarily interested in router and firewall functions, particularly as combined with the convenience of major features of general Linux distributions such as shells, packet filtering, SSH servers, DNS services, file servers, webmin and the like.
 LEAF is a common choice when commercial NAT routers are insufficiently flexible or secure, or are unattractively nonconformant to open source philosophy.

 He also created the distributed revision control system Git and the diving logging and planning software Subsurface.
 He was honored, along with Shinya Yamanaka, with the 2012 Millennium Technology Prize by the Technology Academy Finland "in recognition of his creation of a new open source operating system for computers leading to the widely used Linux kernel".
 He is also the recipient of the 2014 IEEE Computer Society Computer Pioneer Award.
