Antelope air defence system. The Antelope air defense system () is a Taiwanese short range ground-to-air anti-aircraft defense system in operation with the Republic of China Army.

Description 
The Antelope system employs a battery of four Sky Sword I (TC-1) missiles mounted atop a wheeled vehicle (such as a truck or humvee). The system can either be employed as a stand-alone point defense system or as part of an integrated area air defense system.

The Antelope system collectively includes targeting, guidance, communications components as well as the missiles themselves. It was developed beginning in 1995 as an outgrowth of the  Tien Chien-I missile development program.  The precise operating range of the Antelope system is variously reported as 9 km, 18 km, and "4 miles". The system has a crew of two, one gunner and one observer. The system can be controlled from the truck's cabin or from a mobile control console that can be located up to 70m away from the vehicle to increase operator safety and survivability.

The Antelope system's TC-1L interceptors employ infrared guidance and the system is similar in design to the United States-made Chaparral system which historically was a mainstay of Taiwan's SHORAD network.
It can be used to intercept low-flying helicopters, fighter aircraft, attack aircraft, and bombers. The system can engage targets on the move.

CS/MPQ-78 radar 
The system's CS/MPQ-78 radar was developed in the early 1990s and is a 3D pulse doppler radar with full look down-shoot down capability. Max radar range is 46.3km and ceiling is 30,480m.

Jens Axboe. Jens Axboe (born circa 1976) is a Linux kernel hacker.

Work
Axboe is the current Linux kernel maintainer of the block layer and other block devices, along with contributing the CFQ I/O scheduler, Noop scheduler, Deadline scheduler, io_uring, and the splice I/O architecture. Jens is also the author of the blktrace utility and kernel parts, which provides a way to trace every block I/O activity in the Linux kernel. blktrace exists in 2.6.17 and later Linux kernels.

To facilitate his block layer work in the Linux kernel, Axboe created the flexible I/O tester (fio) benchmarking and workload simulation tool. fio is able to simulate various types of I/O loads, such as synchronous, asynchronous, mmap, etc., as well as specifying the number of threads or processes, read vs. write mix, and various other parameters. fio was used to set the record in December 2012 for the highest number of I/Os-per-second (IOPS) in a single system.

In May 2010 Axboe joined Fusion-io after leaving Oracle Corporation. He announced on a mailing list on Friday, January 24, 2014, that he was leaving Fusion-io after 3.5 years to join Facebook.

Dinonylnaphthylsulfonic acid. Dinonylnaphthylsulfonic acid (DINNSA) is an organic chemical, an aryl sulfonic acid.  Its melting point is 259.5 °C and its boiling point is 600.4 °C. It has very low water solubility. It is a moderate skin irritant and a strong eye irritant. It has low volatility and vapor pressure and is stable above 100 °C.

Dinonylnaphthylsulfonic acid is used as an additive in industrial lubricants, greases, cutting fluids, industrial coatings, and corrosion inhibitors. Its calcium and barium salts (CAS numbers  and , respectively) have generally the same use.

Dinonylnaphthylsulfonic acid is a component of Stadis 450 which is an antistatic agent added to distillate fuels, solvents, commercial jet fuels, and to the military JP-8 fuel to increase the electrical conductivity of the fluid. Fluids with increased conductivity more readily dissipate static charges  to mitigate the risk of explosions or fires due to Static Discharge Ignitions

Dinonylnaphthylsulfonic acid by itself does not function as an anti-static additive.

Dinonylnaphthylsulfonic acid is prepared by reaction of naphthalene with nonene, yielding diisononylnaphthalene. Diisononylnaphthalene then undergoes sulfonation.

Rocheport Bridge. The Rocheport Interstate 70 Bridge is a four-lane(soon to be six) bridge over the Missouri River on Interstate 70 (I-70) between Cooper and Boone counties near Rocheport.

The first bridge was built in 1960 and rehabilitated in 1994. Its main span was  and had a total length of . Its deck width was , allowing for four lanes of traffic (two in each direction) and minimal shoulders. Vertical clearance was .

In 2019, the Missouri Department of Transportation received a $81.2 million federal INFRA grant which provided the remaining necessary funding to replace the rapidly aging bridge. On July 1, 2021, MoDOT selected the Lunda Team as the design-build contractor for the project. The design includes two bridges (one for each direction of travel); each bridge will accommodate three travel lanes and full-width shoulders. Construction on the first bridge began in October 2021. The first was done in summer 2023 carrying both westbound and eastbound, will eventually be only carrying westbound only. The original bridge was imploded on the morning of September 10 of the same year. Fog delayed the implosion by over an hour. Footings of the old bridge were removed by blasting on October 30 and November 14.  The second bridge for eastbound traffic will be constructed in the same location as the old bridge. The entire project was completed by the end of 2024. Post offline work with clean up continues through early 2025.

Flash cut. A flash cut, also called a flash cutover, is an immediate change in a complex system, with no phase-in period.

In the United States, some telephone area codes were split or overlaid immediately, rather than being phased in with a permissive dialing period. An example is telephone area code 213, which serves downtown Los Angeles and its immediate environs,  split in January 1951 into 213 and 714 all at once. Another example is an immediate switch from an analog television channel to a digital television channel on the same frequency, where the two cannot operate in parallel without interference.

A flash cut can also define a procedure in which multiple components of computer infrastructure are upgraded in multiple ways, all at once, with no phase-in period.

In film, an extremely brief shot, sometimes as short as one frame, which is nearly subliminal in effect. Also a series of short staccato shots that create a rhythmic effect.

Windows Internal Database. Windows Internal Database (codenamed WYukon, sometimes referred to as SQL Server Embedded Edition) is a variant of SQL Server Express 2005–2014 that is included with Windows Server 2008 (SQL 2005), Windows Server 2008 R2 (SQL 2005), Windows Server 2012 (SQL 2012), Windows Server 2012 R2 (SQL 2012), Windows Server 2016, Windows Server 2019 and Windows Server 2022 (SQL 2014) and is included with other free Microsoft products released after 2007 that require an SQL Server database backend.  Windows SharePoint Services 3.0 and Windows Server Update Services 3.0 both include Windows Internal Database, which can be used as an alternative to using a retail edition of SQL Server. WID was a 32-bit application, even as a component of Windows Server 2008 64-bit, which installs in the path  In Windows Server 2012 and later, it is a 64-bit application, installed in .

Windows Internal Database is not available as a standalone product for use by end-user applications; Microsoft provides SQL Server Express and Microsoft SQL Server for this purpose.  Additionally, it is designed to only be accessible to Windows Services running on the same machine.

Several components of Windows Server 2008 and 2012 use Windows Internal Database for their data storage: Active Directory Rights Management Services, Windows System Resource Manager, UDDI Services, Active Directory Federation Services 2.0, Remote Desktop (standalone) Connection Broker, IPAM and Windows SharePoint Services.  On Windows Server 2003, SharePoint and Windows Server Update Services will install Windows Internal Database and use it as a default data store if a retail SQL Server database instance is not provided.  A Knowledge Base article published by Microsoft states that Windows Internal Database does not identify itself as a removable component, and provides instructions how it may be uninstalled by calling Windows Installer directly.

SQL Server Management Studio Express can be used to connect to an instance of Windows Internal Database using \\.\pipe\MSSQL$MICROSOFT##SSEE\sql\query (2003–2008) or \\.\pipe\MICROSOFT##WID\tsql\query (2012) as instance name. But this will only work locally, as Remote Connections cannot be enabled for this edition of SQL Server. Also note that "Windows Authentication" should be used (as opposed to SQL Server Authentication), and administrators seem to have the best results of authenticating successfully when logged on using the same administrative account that was created when Windows was installed.

Field Programmable Nanowire Interconnect. Field Programmable Nanowire Interconnect (often abbreviated FPNI) is a new computer architecture developed by Hewlett-Packard. This is a defect-tolerant architecture, using the results of the Teramac experiment.

Technology
The design combines a nanoscale crossbar switch structure with conventional CMOS to create a hybrid chip that is simpler to fabricate and offers greater flexibility in the choice of nanoscale devices. The FPNI improves on a field-programmable gate array (FPGA) architecture by lifting the configuration bit and associated components out of the semiconductor plane and replacing them in the interconnect with nonvolatile switches, which decreases both the area and power consumption of the circuit – while providing up to eight times the density at less cost. This is an example of a more comprehensive strategy for improving the efficiency of existing semiconductor technology: placing a level of intelligence and configurability in the interconnect can have a profound effect on integrated circuit performance, and can be used to significantly extend Moore's Law without having to shrink the transistors.

Nakajima Ki-87. The Nakajima Ki-87 was a Japanese prototype, high-altitude fighter-interceptor of World War II. It was a single seat, exhaust-driven turbo-supercharged engined, low-wing monoplane with a conventional undercarriage.

Design and development
The Ki-87 was developed in response to American B-29 Superfortress raids on the Home Islands. It followed up on earlier research by Nakajima and the Technical Division of Imperial Army Headquarters into boosting a large radial engine with an exhaust-driven turbo-supercharger, which had begun in 1942, well before the B-29 raids began. The efforts of the Technical Division of Imperial Army Headquarters eventually culminated into the Tachikawa Ki-94-I, while the Ki-87 was developed as a fall-back project, using less stringent requirements. Nakajima started in July 1943 with the construction of three prototypes, to be completed between November 1944 and January 1945, and seven pre-production aircraft, to be delivered by April 1945. The Technical Division of Imperial Army Headquarters made itself felt during the development of the Ki-87 prototype when they insisted upon placing the turbo-supercharger in the rear-fuselage, and, from the sixth prototype, the Nakajima fighter was to have that arrangement. The Ki-87 had a rearward folding undercarriage to accommodate the storage of ammunition for the cannons, which were mounted in the wing.

Construction was delayed due to problems with the electrical undercarriage and the turbo-supercharger, and the first prototype was not completed until February 1945. It first flew in April, but only five test flights were completed, all with the undercarriage in the extended position.

A further variant, the Ki-87-II, powered by a  Nakajima Ha-217 (Ha-46) engine and with the turbo-supercharger in the same position as the P-47 Thunderbolt, never went further than the drawing board.

Operational history
Production of five-hundred aircraft was planned, but the War ended before any more than the single prototype were built.

Aircraft markings
The sole completed prototype was in natural metal finish; some paintings show a black anti-glare area in front of the cockpit, but this is not seen on any of the known photographs of the plane. However, James P. Gallagher took a photo of the Ki-87 at the abandoned Japanese Army fighter base at Chofu after Japan's surrender. The photo clearly shows a black anti-glare area from the cockpit forward to the tip of the nose.

History of aviation
Canadian Vickers Vancouver. The Canadian Vickers Vancouver was a Canadian transport/patrol flying boat of the 1930s built by Canadian Vickers.

It was a twin-engine, equal-span biplane.  The hull was of metal and the rest of the structure of fabric-covered wood.

Development
The Vancouver was developed as a replacement for the Varuna in response to a Royal Canadian Air Force requirement for a flying boat to transport men and equipment to forest fires. The main difference from the Varuna was a duralumin hull and more powerful engines. The two flight crew were located in two tandem open cockpits, forward of the wing. The main cabin could accommodate a firefighting team of six men and all the required equipment. Five aircraft were delivered to the Royal Canadian Air Force, one was later converted into a coastal patrol aircraft.

Operational history
In the mid-1930s, the Vancouvers were modified as coastal patrol aircraft by the installation of machine guns and bombs.

After the outbreak of the Second World War, Vancouvers served with 4 Squadron, RCAF at Jericho Beach Air Station until withdrawn from service in 1940.  After a brief period of service in training duties, they were finally withdrawn and struck off in 1940.

None of the aircraft saw service after 1940, one private offer to acquire was denied.

Variants
Data from:Canadian Aircraft since 1909
 Vancouver I – prototype with Armstrong Siddeley Lynx IV engines, one built.
 Vancouver IA – designation of prototype after installation of Armstrong Siddeley Lynx IVC engines.
 Vancouver II – production transport version with Armstrong Siddeley Lynx IVC (three aircraft) or Wright J-6 Whirlwind (two aircraft) engines, five built.
 Vancouver IIS/S – conversion of three Lynx-powered Vancouver IIs to "service standard" with three Lewis gun cockpits for coastal patrol, powered by Armstrong Siddeley Serval IV engines.
