Auto-WEKA. Auto-WEKA is an automated machine learning system based on Weka by Chris Thornton, Frank Hutter, Holger H. Hoos and Kevin Leyton-Brown. An extended version was published as Auto-WEKA 2.0. Auto-WEKA was named the first prominent AutoML system in a neutral comparison study.

It received the test-of-time award of the SIGKDD conference in 2023.

Description 

Auto-WEKA introduced the Combined Algorithm Selection and Hyperparameter optimization (CASH) problem, that extends both the Algorithm selection problem and the Hyperparameter optimization problem, by searching for the best algorithm and also its hyperparameters for a given dataset. Baratchi et al. state that "[T]he real power of AutoML was unlocked through the definition of the combined algorithm selection and hyperparameter optimisation problem".

The CASH for formalism was picked up and also extended by later AutoML systems and methods such as Auto-sklearn, ATM,  AutoPrognosis, MCPS, MOSAIC, naive AutoML and ADMM.

John C. Gotwals. John Carl Gotwals (November 4, 1884 – January 15, 1946) was an American military engineer. His long career in the Corps of Engineers included a term (1930–1934) as the Engineer Commissioner of the District of Columbia.

Early life
Gotwals was the son of Abraham G. Gotwals (1850–1911) and Mary Carroll Logan Gotwals (1859–1943); he had at least four siblings, three of whom were older. He graduated from Pennsylvania State College in 1906 with a B.S. degree in civil engineering. Continuing graduate studies at Penn State, he earned a Civil Engineer degree in 1907. Gotwals then worked as a civil engineer for the Pennsylvania Railroad and the Catskill Aqueduct. In March 1913, he joined the army as a probationary second lieutenant; from 1915 to 1917, he was a student at the Army Engineer School in Washington.

Career
In 1917, Gotwals was sent to France in command of a special unit of students from the Washington, D.C. Bliss School of Electricity, tasked with teaching the use of searchlights. Gotwals was raised to the rank of lieutenant colonel and was in 1922 awarded a Distinguished Service Medal for his work there. After World War I,  he accepted a reduction in rank to major to remain in active service. He served on the Alaska Engineering Commission and the Alaska Road Commission, serving as president of the latter for a time in 1920. He then completed his studies at the Army Engineer School, graduating in 1921. In 1922, he was called in to investigate the Knickerbocker Theatre roof collapse in Washington, DC. He also served in engineering posts in Mississippi and, from 1924 to 1930, in St. Louis, Missouri.

On July 21, 1930, he was appointed as the Corps of Engineers representative on the three-person Board of Commissioners in charge of the District of Columbia; he served until August 22, 1934. He also served on the district's Public Utilities Commission. Gotwals was ill for much of his term and was replaced in 1934 due to his impending retirement for health reasons. He was raised again to the rank of lieutenant colonel upon his retirement on September 30, 1934.

Gotwals was a member of the American Society of Military Engineers and the American Society of Civil Engineers.

Personal life
Gotwals married Muriel Clemmons (1900–1989) on November 10, 1927. He died at St. Mary's Hospital in Richmond Heights, Missouri near St. Louis on January 15, 1946.

British Rail Class 897. The British Rail Class 897 is a type of tri-mode electro-diesel multiple unit to be manufactured by CAF for London North Eastern Railway. Ten ten-car units will be built.

History
In 2013, the Department for Transport ordered 30 Class 801s to replace the same number of InterCity 225s on East Coast Main Line services. However after Virgin Trains East Coast was awarded the InterCity East Coast franchise in 2015 with a commitment to introduce extra services, some InterCity 225s were retained.

In October 2020, London North Eastern Railway (LNER) issued a tender for 10 electro-diesel multiple units to replace its remaining InterCity 225s. In November 2023, LNER placed an order with CAF for ten ten-carriage sets to be built on its Civity platform. The first two will be built in Spain, the other eight at Newport.

The trains will be able to run on 25kV 50Hz electrification, battery and diesel power. They will be maintained at Neville Hill TMD.

Mugere Hydroelectric Power Station. MugereHydroelectric Power Station () is an  run-of-the-river hydroelectric power station in the Bujumbura Rural Province of Burundi.

Location

The 8 MW Mugere Hydroelectric Power Station is in the Commune of Kabezi, Bujumbura Rural Province.
It is along the Mugere River.
The plant is south of Bujumbura. 
It contains four 2-MW units.
It delivers 40 GWh per year.
The original purpose of the plant was to provide power to a Chinese textile mill and to Bujumbara.

Construction and rehabilitation

The Mugere plant was the first hydroelectric plant in Burundi.
The government of China financed its original construction in the late 1970s and early 1980s.
It was commissioned in 1982.
A 35 kV line was built in 1982 linking the Mugere hydroelectric plant to Bujumbura.

Successive rehabilitation projects were undertaken with Chinese financing in 1987, 1993, 2000 and 2009–2010.
The 2009–2010 project was undertaken by Hebei Hydraulic Engineering Bureau, China First Highway Engineering Company and China Road and Bridge Corporation, and was handed over on November 15, 2010.

As of 2010 the power station provided almost 30% of the electricity supplied to the city of Bujumbura, and 40% of the hydroelectric capacity of the state-owned water and power utility Regideso, Burundi.
The output of the Mugere hydroelectric generating station drops considerably in the dry season since it has no reservoir to store water, but relies on the river flow.

International Electricity Company of the Great Lakes Countries. The International Electricity Company of the Great Lakes Countries (, SINELAC)  supplies electricity to Burundi, Rwanda and the Democratic Republic of the Congo.

Purpose

SINELAC is an organization of the Economic Community of the Great Lakes Countries (CEPGL), with head office in Bukavu, the Democratic Republic of Congo.
It was created in 1983 by an agreement between the three CEPGL countries for the purpose of operating the Ruzizi II Hydroelectric Power Station and marketing the energy produced to the national electricity companies of the three member countries: REGIDESO Burundi, Société Nationale d'Électricité in the Democratic Republic of Congo and Energy Utility Corporation Limited in Rwanda.

The Ruzizi II Hydroelectric Power Plant is on the Rusizi River between Rwanda and the DRC.
It was built between 1983 and 1898.
Construction was funded through development credit agreements between the member countries and the International Development Association, under which each country assigned the funding received to SINELAC, which would undertake the project.
Ruzizi II delivers a maximum of 44 MW, and has potential annual production of 200 GWH.
Between 1991 and 2001 SINELAC provided, on average, 45% of Rwanda's electricity, 17% of Burundi's electricity and 21% of the DRC's electricity.

Moak Rollins. Henry Moak Rollins (September 11, 1921 – January 27, 2005) was a chairman of the Public Utility Commission of Texas from 1982 to 1983.

Education and career
Born in Gulfport, Mississippi, Rollins received a B.S. in Mechanical Engineering from Texas A&M University in 1942, and thereafter served as an engineering officer and pilot in the United States Army Air Forces during World War II, stationed in Iran and Italy. His military service concluded in 1946, and he thereafter joined the Hughes Tool Company in Houston, Texas, in 1947, remaining until he left in 1951 to serve as a founding member of what would become Drilco Oil Tools. He remained with Drilco until 1967, when it was acquired by Smith International.

Rollins then left the business world to pursue a master's degree in business administration at University of Texas at Austin, followed by a doctorate in finance at the same institution, becoming a member of the faculty in 1973. Rollins was a lecturer at the University of Texas until August 1979, when Governor Bill Clements, with whom Rollins had become friends years earlier, appointed him to a seat on the Public Utility Commission.

Rollins later became chair of the PUC, and in 1983, following the election of Governor Mark White, who had campaigned in part on criticism of the PUC, Rollins found himself the target of criticism for the decisions of the commission. Rollins resigned from the PUC in March 1983, in protest against the rhetoric of Governor White, whom Rollins deemed "unprincipled and dishonest"; the other two members of the PUC having already resigned and been replaced by White, Rollins said that he was resigning in part to ensure that White was "held personally responsible" for the actions of the PUC, which would then be composed only of White's appointees.

Personal life and death
On October 20, 1946, Rollins married Viola Emogene Broaddus, in Houston, Texas, with whom he had three sons. He died in Austin, Texas, at the age of 83.

Sewbo. Sewbo is an industrial sewing robot invented by Sewbo, Inc., a company based in Seattle, Washington.

History 
The company Sewbo, Inc was founded by Jonathan Zornow in 2015. The robot capable of handling fabric components throughout the entire garment production process. The operation relies on a water-soluble, non-toxic polymer called polyvinyl alcohol, which stiffens the fabric to facilitate manipulation during sewing. While Sewbo is currently optimized for producing T-shirts. It can sew a T-shirt from start to the end. The process involves cutting fabric panels, stiffening them with a polymer solution, and feeding them into a sewing machine using a robotic arm equipped with suction cups.

Operating Systems Design and Implementation. The Symposium on Operating Systems Design and Implementation (OSDI), organized by  USENIX, is one of the two top academic conferences on systems research, along with SOSP. A number of notable systems were first published as OSDI papers, including MapReduce, Bigtable, Spanner, and TensorFlow.

History
Until the early 1990s, SOSP was the main venue for the systems community to meet and publish work, but it was held only once every two years. In 1994, this led to the creation of OSDI as an alternative venue for years in which SOSP was not held. The idea came from Jay Lepreau, who also served as the first program chair. In the following years, OSDI and SOSP took turns as the top-tier systems conference of the year. However, the systems community kept growing and, as single-track conferences, both could accept only a limited number of papers; thus, acceptance rates dropped significantly. This led to a community proposal to turn both into annual conferences, which was accepted by SIGOPS. As a result, OSDI became an annual conference in 2021.

Preamble (company). Preamble is a U.S.-based AI safety startup founded in 2021. It provides tools and services to help companies securely deploy and manage large language models (LLMs). Preamble is known for its contributions to identifying and mitigating prompt injection attacks in LLMs.

History 

Preamble is particularly notable for its early discovery of vulnerabilities in widely used AI models, such as GPT-3, with a primary discovery of the prompt injection attacks. These findings were first reported privately to OpenAI in 2022 and have since been the subject of numerous studies in the field.

Preamble has entered a partnership with Nvidia to improve AI safety and risk mitigation for enterprises. They are a part of the Air Force security program as a notable Pittsburgh AI hub. Since 2024, Preamble has partnered with IBM to combine their guardrails with IBM Watsonx.

Research  

Preamble's research revolves around AI security, AI ethics, privacy and policy regulations. In May 2022, Preamble's researchers discovered vulnerabilities in GPT-3 which allowed malicious actors to manipulate the model's outputs through prompt injections. The resulting paper investigated the vulnerability of large pre-trained language models, such as GPT-3 and BERT, to adversarial attacks. These attacks are designed to manipulate the models' outputs by introducing subtle perturbations in the input text, leading to incorrect or harmful outputs, such as generating hate speech or leaking sensitive information.

Preamble was granted a patent by the United States Patent and Trademark Office to mitigate prompt injection in AI models.

Carrosseriefabriek Pennock. Carrosseriefabriek Pennock, short for Carrosseriefabriek P. J. Pennock & Zonen, was a Dutch coachbuilding company.

History 
Johannes Jacobus Pennock founded the company in The Hague in 1884. Another source states 1898. Initially he manufactured carriages. After his death his son Piet ran the company. In 1886 Jacob van den Bergh took over the company.

In 1900, the production of bodies for automobiles and buses began. Customers included FN. From the 1920s, both individual bodies and larger series production of convertibles were produced, mainly based on somewhat more expensive chassis from Buick, Nash, Packard and Studebaker.

In the 1940s, bodies were made for the Story brand electric cars of the Internationale Automobiel Maatschappij. Pennock also built individual bodies on the basis of Alvis, Alfa Romeo, Kaiser, Riley, Healey, Lagonda, Talbot-Lago, Minerva and Škoda chassis'. The Dutch royal family took delivery of an Austin A125 from Pennock, which still exists today. 

In 1953 or 1954 the company was dissolved.

List of fake buildings in Toronto. This is a list of fake buildings in Toronto, Canada. After the end of World War II, electric demand grew exponentially. Toronto Hydro built house-shaped substations with slight variations from six base models ranging from ranch-style houses to Georgian mansions. The exterior designs of residential buildings allowed them to enclose substations in residential neighborhoods without much opposition from the communities as they blended in with their neighboring houses. Throughout the 20th century, the company built hundreds of these fake houses in Toronto area.
