Koshiki-2 Experimental Fighter. The Koshiki-2 Experimental Fighter was a prototype fighter aircraft designed by the Tokorozawa Aviation School of the Imperial Japanese Army. It was a single-engined, single-seat biplane and was the first single-seat fighter of wholly Japanese design and construction. Two were built and flown in 1922 and 1923, but no further production followed.

Design and development
The Provisional Military Balloon Research Association (PMBRA) (Japanese:Rinji Gunyo Seiki Kikyu Kenkyu Kai) was established at Tokorozawa, Saitama on 30 July 1909 as a joint venture by the Imperial Japanese Army and the Imperial Japanese Navy to develop both lighter-than-air and fixed wing aircraft. It soon became dominated by the Army and developed a series of experimental aircraft as well as coordinating aviation research and aircraft procurement for the Army. The PMBRA was shut down in April 1919, with the Army Aviation School established at the same site. The aircraft research and design capability of the PMBRA was taken over by the Department of Research at the Army Aviation School.

In 1920, the Department of Research started the design of a new single-seat fighter, the Koshiki-2 (School Type 2, as it was designed at the Army Aviation School). The design was a single-engined tractor configuration biplane of wood and fabric construction and of similar design to the French SPAD XIII fighter. It had single-bay wings with single I-shape interplane struts and had an all-moving horizontal tailplane. It was powered by a single  Salmson 9Z water-cooled radial engine.

The first example was completed and flown in 1922. It was the first single-seat fighter of wholly Japanese design and construction. Its performance was good, reaching a speed of , but, although handling was generally acceptable, the aircraft was found to have poor horizontal stability at low speeds. It was wrecked in a landing accident during the aircraft's fourth flight, when it overshot the landing ground. A second prototype was completed in 1923, but it was found to be still unstable at low speeds, and no further development or construction took place.

Sri Lanka Railways M8. Sri Lanka Railways Class M8 is a class of Sri Lankan diesel-electric locomotive that was developed by Banaras Locomotive Works at Varanasi, India, in 1996. This class of locomotives was fitted with  V16 power units. This is used on both passenger and freight trains on Sri Lanka Railways.

Performance
This locomotive is capable of hauling 20 carriages at once but usually not used to haul more than 18 carriages. Major problems that are seen in this class are maintenance difficulties and corrosion.

Sub classes

M8A

Two (877 & 878) short truck M8A locomotives were delivered in 2001. They were imported to use on Upcountry main line, but it was impossible to run them due to their wheel design of HAHS bogie without equaliser beams. M8A locomotives were built using  V12 power units.

Current operation
M8 and M8A are not used on the Main Line above Nawalapitiya and on the Kelani Valley Line but are operated on other lines. This locomotive is used when it need to pull much heavy load. Mainly used in flat lines like Northern Line, Trincomalee Line, Batticaloa Line and Coastal Line.

Depot for the M8s is Diesel Electric Locomotive Shed at Maradana.

Accidents and incidents
 M8A No. 878 was seriously damaged in an accident with a concrete mixing transport truck. Since the accident, the locomotive has been repaired and put back into service.

McDonald delivered an TEDx talk at the 2021 Annual Ideas Conference organised by TEDxUniversity of Strathclyde under the theme "Resilience Reignited". During his TED talk, McDonald discussed a systems engineering approach to achieving net zero by 2050 which includes the use of steam reforming. "Net Zero" means not adding to the amount of greenhouse gases in the atmosphere - achieving this means reducing emissions as much as possible as well as balancing out those that remain by an equivalent amount 

He highlighted the factors in energy which need to be taken in consideration if we are to achieve a decarbonised future - factors such as affordability, reliability, economic opportunity and public engagement. He spoke about the importance of leadership, policy making and resilient infrastructure in the goal towards creating a sustainable future.

Arch Linux ARM. Arch Linux ARM is a port of Arch Linux for ARM processors. Its design philosophy is "simplicity and full control to the end user," and like its parent operating system Arch Linux, aims to be very Unix-like. This goal of minimalism and complete user control, however, can make it difficult for Linux beginners as it requires more knowledge of and responsibility for the operating system.

History and development 
Arch Linux ARM is based on Arch Linux, which is a minimalist Linux distribution first released on March 11, 2002. The idea of making a single,  official port of Arch Linux for devices with ARM processors was born from members of the Arch Linux PlugApps and ArchMobile development teams, notably Mike Staszel, who went on to found the Arch Linux ARM project.

Kevin Mihelich is currently Arch Linux ARM's primary developer. Arch Linux ARM is community-developed, with software development and user support provided fully by volunteer effort and donations. Also, unlike other community-supported operating systems such as Ubuntu, Arch Linux ARM has a relatively small user base, making user participation in development especially important.

Arch Linux ARM follows a rolling release cycle, i.e. new software is packaged as it is released. This "bleeding edge" release cycle of small, frequent package updates differs from release cycles of Linux distributions such as Debian, which focus on large, scheduled releases of packages proven to be stable.

Supported processors 
Unlike Arch Linux, which is aimed at x86-64 CPUs, Arch Linux ARM targets ARM CPUs and, as a result, many single-board computers such as the Raspberry Pi.

There is support for:

 ARMv7 1st generation Cortex-A8 platforms, such as the BeagleBoard or Cubieboard
 ARMv7 2nd generation Cortex-A9 and Tegra platforms, such as the PandaBoard or TrimSlice
 ARMv7 3rd generation Cortex-A7 and Cortex-A15 platforms, such as the Cubieboard2, Odroid XU, Samsung Chromebook (series 3), Samsung Chromebook 2 or Raspberry Pi 2
 ARMv8 64-bit capable Cortex-A53 and Cortex-A72 platforms, such as the Odroid C2 and N2, Acer Chromebook R13 or Raspberry Pi 3.

Arch Linux ARM can run on any device that supports ARMv7 or ARMv8 instruction sets, including the 64-bit ARMv8 instruction set of the Raspberry Pi 3 and 4.

There are officially supported platforms and community-supported ones as well.

Reception 
Arch Linux ARM has gained popularity as a lightweight Linux distribution, and in 2014 was growing in popularity among single-board computer hobbyists. Arch Linux ARM is also known for having good community support.

Celery (software). Celery is an open source asynchronous task queue or job queue which is based on distributed message passing. While it supports scheduling, its focus is on operations in real time.

Overview
The execution units, called tasks, are executed concurrently on one or more worker nodes using multiprocessing,  or . Tasks can execute asynchronously (in the background) or synchronously (wait until ready). Celery is used in production systems, for services such as Instagram, to process millions of tasks every day.

Technology
Celery is written in Python, but the protocol can be implemented in any language. It can also operate with other languages using webhooks. There is also a Ruby-Client called RCelery, a PHP client, a Go client, a Rust client, and a Node.js client.

Celery requires a message broker to run. As of October 2024, Redis and RabbitMQ are supported and actively maintained and monitored. Amazon SQS is supported and maintained but does not support worker inspection and management at runtime, while Zookeeper and Kafka are currently in experimental development.

PLaSM. PLaSM (Programming Language of Solid Modeling) is an open source scripting language for solid modeling, a discipline that constitutes the foundation of computer-aided design and CAD systems. In contrast to other CAD programs, PLaSM emphasizes scripting rather than interactive GUI work. Users can create arbitrarily complex designs using a wide range of simple 2D and 3D objects, advanced curves and curved surfaces, Boolean operations, and elementary as well as advanced geometric transformations.

The scripting approach is very different from working with an interactive graphical user interface (GUI). Although it means less user comfort, it is preferred by numerous CAD instructors as scripts reveal all details of the design procedure (not only the final design) and students are exposed to elementary computer programming.

History
PLaSM has been developed since the 1980s by the CAD group at the Universities Roma Tre and La Sapienza in Rome, Italy, by Alberto Paoluzzi and his collaborators. It was used at the University of Rome to create an extensive database of ancient Rome architecture.

Polish Federation of Engineering Associations. The Polish Federation of Engineering Associations ( (NOT)), translated interchangeably as: the Polish Chief, Main or Central Technical Organization; also known as  (FSNT) in Polish, is the biggest Polish association representing professional engineers and technicians with 110,000 members and 49 regional branches (Engineering Associations) across the country. Its headquarters have been in Warsaw since 1905.

A similar organization was founded in 1835 in Paris, France as the Polish Polytechnical Society, during the military Partitions of Poland by foreign powers. Since 1905 the association of Polish engineers has had a permanent office in Warsaw at Dom Technika located at ul. Czackiego 3/5. After World War II, the organization was re-activated on the initiative of Bolesław Rumiński in already liberated Warsaw on December 12, 1945. It was commonly known as NOT in Communist Poland, and renamed after the Revolutions of 1989 as the NOT Federation (Federacja Stowarzyszeń Naukowo-Technicznych – NOT). Since June 28, 2005 it had been called the Federation of Engineering Associations of Poland (Federacja Stowarzyszeń Naukowo-Technicznych w Polsce).

Szkieletor controversy
In the Edward Gierek decade in Communist Poland, the Naczelna Organizacja Techniczna NOT began the construction of the 92-metre  high-rise building known as the NOT Tower in Kraków. It was intended to provide a large amount of office space. The concrete shell was erected in 1975, but the building was never finished, because of economic constraints and political unrest leading to the imposition of martial law in Poland in 1981. In time, due to the unfinished (and blackening) building's resemblance to a skeleton, it was nicknamed "Szkieletor" by the people of Kraków after Skeletor, the arch-villain in He-Man and the Masters of the Universe, a cartoon popular in Poland at that time.

For years the structure remained the biggest eyesore in the Kraków skyline, reportedly named by the editors of Huffington Post as one of the top-ten "post-apocalyptic" (i.e. abandoned and deserted) buildings in the world. The "NOT Tower" has since 2005 been owned by TreiMorfa Project, who have expressed interest in renovating it. Apparently, its controlled demolition suggested earlier by the British firm Medinbrand Ltd. has been rejected by the Magistrate after further inspections, due to its structural stability. More recently, in December 2011 the heated debate about its possible future, based on brand new plans by TreiMorfa, has been cut short by the local courts for legal reasons. Those most disappointed, it seems, are the average citizens.
