Carlin Tunnel. The Carlin Tunnel is a collective name for a set of four tunnel bores in the Humboldt River's Carlin Canyon, east of Carlin in Elko County, Nevada, United States. The two railroad bores were constructed for different purposes at different times, while the two highway bores were constructed concurrently, all with the goal of bypassing a sharp bend in the river. Currently, two of the bores carry Interstate 80, while the other two bores carry Union Pacific Railroad's Overland Route and Central Corridor. Bridges over the Humboldt River are adjacent to both portals of three tubes, including the two freeway bores and one of the railroad bores.

History

The first bore was constructed by the Southern Pacific Railroad in 1903 as part of a straightening of the First transcontinental railroad, prior to this time the railroad followed the curved river through the canyon. The second tunnel was constructed by the Western Pacific Railroad for the Feather River Route. The modern Union Pacific Railroad, which acquired both of these railroad companies, has combined the former competing lines into a dual-track directional running main for uninterrupted traffic, now known as the Elko Subdivision. The former Southern Pacific bore crosses the Humboldt river at each portal, similar to the freeway bores, while the former Western Pacific bore does not cross the river at the tunnel portals. U.S. Route 40 was originally routed on the old railroad grade through the canyon. With the planned construction of Interstate 80 through the area, a third and fourth bore was constructed to accommodate the expected traffic increase and higher traffic speed; these were completed and opened on September 25, 1975. The estimated cost to build the tunnels was US$8 million (equivalent to $ in ); at the time this was the most expensive single construction contract awarded by the Nevada Department of Highways, predecessor agency to the Nevada Department of Transportation. Completion was originally scheduled for late 1974, however during boring fragmented rock was discovered which slowed progress.

In addition to these larger tunnels, both railroad grades feature several smaller tunnels as the railroad follows Carlin Canyon and downstream Palisade canyon of the Humboldt River. The railroad bridges and tunnels near Carlin have made news on a few occasions. In 1908, a rock slide nearly caused the Southern Pacific tunnel to collapse resulting in a massive effort to save the rail line. In 1939, the City of San Francisco passenger train derailed on one of the Humboldt river bridges, killing 24 and injuring 121. The incident was ruled sabotage, but remains unsolved. In 2008, a train derailment at a smaller tunnel west of Carlin led to the collapse of one of the Humboldt River bridges. This bridge collapse resulted in nationwide rail traffic delays.

Western Corridor Recycled Water Scheme. The Western Corridor Recycled Water Scheme, a recycled water project, is located in the South East region of Queensland in Australia. The scheme is managed by Seqwater and forms a key part of the SEQ Water Grid constructed by the Queensland Government in response to population growth, climate change and severe drought. The 2.5 billion project is reported as the largest recycled water project in Australia. As of 2019, the scheme has been constructed and its performance has been validated. It remains in care and maintenance mode, and will commence operation after SEQ Water Grid dam levels reach 60%.

Location and features

The scheme involved the construction of three advanced water treatment plants constructed at Bundamba, Luggage Point and Gibson Island, which draw water from six existing wastewater treatment plants in the region to produce up to  of purified recycled water daily. The treatment train consists of microfiltration, reverse osmosis, ultraviolet light with advanced oxidation and chlorine disinfection.

The water is distributed via a network of pipelines measuring more than  in length. Construction began on the Recycled Water Project in 2006 and completed in late 2008. 408 million of funding was provided by the Australian Government via its Water Smart Australia Program.

In Stage 1 of the project the scheme has provided an alternative water source for Swanbank Power Station and both Tarong Power Station and Tarong North Power Station. Supplies to Swanbank started in 2007 and supplies to Tarong and Tarong North started in June 2008.

The system has the capacity to provide water to other industrial users, agricultural users and to supplement drinking water supplies in Wivenhoe Dam. Testing of the pipeline to Wivenhoe Dam has been conducted, however in November 2008, Premier Anna Bligh declared that recycled water will not enter the dam unless levels drop to below 40%. Initially, the three power stations were the main customers of the recycled water, consuming  per day.

Since coming online in August 2007, through to July 2010, the Western Corridor Recycled Water Scheme has supplied more than  of water into the SEQ Water Grid.

In January 2013 it was reported that the Newman government was considering shutting down part or all of the scheme.

Bridge Mill Power Plant. The Bridge Mill Power Plant is an historic hydroelectric plant situated at 25 Roosevelt Avenue in Pawtucket, Rhode Island. The plant is housed in a red brick building with sections ranging from two to three stories in height, located on the west bank of the Seekonk River. A notable feature of the site is an ashlar granite retaining wall, which hides the conduit that channels water from the Pawtucket Falls Dam to the facility.  

The power plant is composed of three primary sections: the gate house, which regulates the water flow into the power house, where five turbines were originally installed; and the boiler house, which contained a steam generation system used when water levels were insufficient for hydroelectric power production. Constructed in 1893, the Bridge Mill Power Plant is considered one of the best-preserved 19th-century hydroelectric stations in Rhode Island.

Due to its historical significance, the plant was listed on the National Register of Historic Places in 1983.

Helix (video game). Helix is a music video game for WiiWare by Ghostfire Games for 1000 Nintendo Points. The objective of the game is to accurately copy gestures with the Wii Remote to the beat of the music. The game encourages players to use two Wii Remotes to play, and features 26 music tracks from independent musicians.

Helix was released on August 25, 2008 in North America and on September 26, 2008 in Europe.

Gameplay

The player is required to copy the arm motions of a robot that dances on screen using their Wii Remotes. The player is first shown the motion, and then must perform it afterward, similar to the game simon says. A "Rhythm Track" scrolls across the top of the screen, indicating to the player when it is time for to do the motion.

When the robot does a move, a "Move Bar" appears on the Rhythm Track. The Move Bar starts traveling left on the Rhythm Track after it appears. The player must then time their motion so that it is halfway completed by the time the center of the Move Bar passes by the halfway mark of the Rhythm Track. Once completing the motion, if the Move Bar turns green, the player has performed the gesture correctly, if it turns red, the move was performed incorrectly. In addition, like other music games, Helix also features a gauge that fills up with every successful move, and depletes with every failed move.

Development

Helix was designed with as "a video game that happens to burn calories as a side benefit". In order to keep the game under the 40mb size limit imposed by Nintendo, the developers used various technologies such as music visualization instead of custom animation, and used audio compression to fit the 26 songs into the game.

Reception

Helix received an 8.0 out of 10 from WiiWare World, saying "as it is, Helix is a refreshing entry into the rhythm action genre and, without a doubt, one of the more worthwhile additions to WiiWare. If you weren't a fan of such titles before then we don't expect you to be won over by it, but if you enjoy a fun game that tries something different (and succeeds) then we can heartily recommend Helix to you. It is definitely worth the asking price."

GameFocus were also positive, scoring Helix an 85/100, the reviewer noting "I was blown away by the unique gameplay and simple concept behind the game, which makes this one of the best Wii and downloadable games this year. If you enjoy rhythm games this one will be one of your favorites."

In contrast, IGN gave the game 4.3/10, citing "shallow" motion controls and "blah" visuals, and showing little fondness for the game's techno soundtrack.

GamingTarget did two reviews of the title due to opposing views by their writers. One reviewer found fault with "the lack of precise movement, uneven challenge, and uninspired music selection" of the game, while the other felt that Ghostfire made "a fun, but bare-bones package" and called for a more fleshed-out edition.

Pawtucket City Hall. Pawtucket City Hall is located at 137 Roosevelt Avenue, just outside the central business district of Pawtucket, Rhode Island. The Art Deco-style building was designed by Providence architect John O'Malley and was built in 1933–1936, its cost subsidized by funds from the Works Progress Administration.

Building description
Pawtucket City Hall has a large central entrance block, faced in limestone. three bays wide and three stories high, with an attic story fenestrated with three screened windows, and above that, a panel inscribed, “Pawtucket City Hall.” The central section is surmounted by a tower faced in brick and stone, which rises to a height of  above grade. The design of the central wing and tower derives, whether consciously or not, from the Nebraska State Capitol, an influential building, designed by architect Bertram Goodhue in 1920, and completed in 1932.

The main block is flanked by two wings, faced in brick, with pitched roofs, each six bays wide and three stories high (plus a basement level), which house the Pawtucket City Hall offices. The two principal wings each extend to secondary projecting wings that are two stories high, faced in brick, with flat roofs giving them a more utilitarian character. The north wing houses the central fire station, while the south wing houses the police department headquarters.

The building was added to the National Register of Historic Places in 1983. In 1999, it made a brief appearance in the movie Outside Providence.

Virtual file server. In computing, a virtual file server is a system consisting of one or more virtualized devices that store computer files such as documents, sound files, photographs, movies, images, or databases. The server can be accessed by workstations or application servers through the Virtual Fileserver Network (VFN).

The term "server" highlights the role of the virtual machine in the client-server scheme, where the clients are the applications accessing the storage. The file server usually does not run application programs on behalf of the clients. It enables storage and retrieval of data, where the computation is provided by the client. With a storage area network (SAN), the server(s) act purely as virtual storage devices, with a client maintaining the file system. With network-attached storage (NAS), the server(s) manage the file system. Both SAN and NAS servers may be virtualized, so the users do not have to know which physical devices are hosting the files. 
A virtual file server typically combines the security of virtual private networks (VPN) with file synchronization, distribution and sharing services of network file servers.

Various companies offer software for use by an organization in managing virtual file servers. The operating system may be stripped-down, concerned only with file management functions such as synchronizing redundant copies of the file, failure recovery, handling concurrent updates from different clients and enforcing client access rights. Some companies offer virtual file servers as a service to organizations that prefer to outsource server operations, with the servers residing in the "cloud".

Nyetimber Mill. Nyetimber Mill  is a grade II listed tower mill at Pagham, Sussex, England which has been converted to residential use.

History

Nyetimber Mill was built in the early 1840s and was working until tailwinded in 1915. The sails were on the mill until they were struck by lightning in 1927. The mill became derelict and was burnt out in 1962, leaving the windshaft perched above the ivy covered tower.  The mill was converted to a house by 2005.

Description

Nyetimber Mill is a four-storey brick tower mill with an ogee cap. It had four Patent sails and was winded by a fantail. The mill drove two pairs of millstones. An external pulley enabled the mill to be worked by an engine. This has been retained in the converted mill.

Ddrescue. GNU ddrescue is a data recovery tool for disk drives, DVDs, CDs, and other digital storage media. It copies raw blocks of storage, such as disk sectors, from one device or file to another, while handling read errors in an intelligent manner to minimize data loss by scraping good sectors from partially read blocks.

GNU ddrescue is written in the C++ programming language, and is available as open-source software that was originally released in 2004. It is also available in binary form as a component in most Linux distributions.

Description
ddrescue uses a sophisticated algorithm to copy data from disk drives, and other storage devices, causing as little additional damage, if they are failing, as possible. It is considered to have the most sophisticated implementation of a block-size-changing algorithm in free and open source software, and is considered an essential data recovery tool.

The status of the copy process is recorded in a map file (previously called logfile) that aids in the progress of multiple stages of the recovery algorithm, and facilitates interrupting the recovery, and repeating it as needed to recover more data. The program does not write zeros to the output in place of bad blocks, so that additional errors not encountered previously do not destroy previously recovered blocks. This makes it possible to merge multiple defective copies of CDs or DVDs into one backup file. By virtue of the map file, only the needed blocks are read from the second and successive copies.

ddrescue also features a fill mode, able to selectively overwrite parts of the output file, which has uses such as wiping data, marking bad areas or even, in some cases, repair damaged sectors.

Unrelated recovery tools
GNU ddrescue is not a derivative of dd which also copies blocks of storage from disk storage, but does not operate in a strategic, algorithmic manner.

GNU ddrescue is also distinct from the similarly named program .

Ovenden's Mill, Polegate. Ovenden's Mill or Mockett's Mill is a grade II* listed tower mill at Polegate, East Sussex, England which has been restored but is now in a poor state and the tower is not open to the public. The impressive milling museum is open but only on certain Open Days.  If you look at the "Polegate windmill" Facebook page you will find more details.  We are arranging these days at the moment but the first one should be National Mills weekend with the mill open on the Sunday.

History

Ovenden's Mill was built in 1817 and was working by wind until 1943. The mill was worked by auxiliary engine, latterly an electric motor, until 1965. By the time the mill stopped working, it was becoming derelict. Eastbourne and District Preservation Trust bought the mill and grounds, and a restoration was carried out by E Hole and Sons, the Burgess Hill millwrights. One of the new stocks broke in July 1974, bringing the sail with it. This particular stock was only seven years old. Thompson's, the Alford millwrights fitted a replacement stock and two new sails in May 1976. Further restoration work was undertaken in 2004, including the fitting of a cowl to the adjoining malthouse. Two new sails were fitted in 2009.

Description

Ovenden's Mill is a four-storey brick tower mill with a domed cap winded by a fantail. There is a stage at first floor level. It had four Patent sails carried on a cast iron Windshaft. The Brake Wheel is wooden. The mill drove two pairs of overdrift millstones, with a third pair driven underdrift by auxiliary engine. The tower is  high to the curb.

Benevolent dictator for life. Benevolent dictator for life (BDFL) is a title given to a small number of open-source software development leaders, typically project founders who retain the final say in disputes or arguments within the community. The phrase originated in 1995 with reference to Guido van Rossum, creator of the Python programming language.

History
Shortly after Van Rossum joined the Corporation for National Research Initiatives, the term appeared in a follow-up mail by Ken Manheimer to a meeting trying to create a semi-formal group that would oversee Python development and workshops; this initial use included an additional joke of naming Van Rossum the "First Interim BDFL". According to Rossum, the title was most likely created by Ken Manheimer or Barry Warsaw.

In July 2018, Van Rossum announced that he would be stepping down as BDFL of Python without appointing a successor, effectively eliminating the title within the Python community structure.

Usage
BDFL should not be confused with the more common term for open-source leaders, "benevolent dictator", which was popularized by Eric S. Raymond's essay "Homesteading the Noosphere" (1999).

Among other topics related to hacker culture, Raymond elaborates on how the nature of open source forces the "dictatorship" to keep itself benevolent, since a strong disagreement can lead to the forking of the project under the rule of new leaders.
