Symposium on Operating Systems Principles. The Symposium on Operating Systems Principles (SOSP), organized by the Association for Computing Machinery (ACM), is one of the most prestigious single-track academic conferences on operating systems.

Before 2023, SOSP was held every other year, alternating with the conference on Operating Systems Design and Implementation (OSDI); starting 2024, SOSP began to be held every year.  The first SOSP was held in 1967. It is sponsored by the ACM's Special Interest Group on Operating Systems (SIGOPS).

History 
The inaugural conference was held in Gatlinburg, Tennessee on 1–4 October 1967 at the Mountain View Hotel. There were fifteen papers in total, of which three presentations were in the Computer Networks and Communications session. Larry Roberts presented his plan for the ARPANET, a computer network for resource sharing, which at that point was based on Wesley Clark's proposal for a message switching network. Jack Dennis from MIT discussed the merits of a more general data communications network. Roger Scantlebury, a member of Donald Davies' team from the UK National Physical Laboratory, presented their research on packet switching in a high-speed computer network, and referenced the work of Paul Baran. At this seminal meeting, Scantlebury proposed packet switching for use in the ARPANET and persuaded Roberts the economics were favorable to message switching. The ARPA team enthusiastically received the idea and Roberts incorporated it into the ARPANET design.

In total, 29 conferences have been held, seven of which were outside the USA. The first conference held outside the USA was in Saint-Malo, France in 1997. Other countries to have hosted the conference are Canada, the UK, Portugal, China and Germany.

List of conferences 
From 1967 to 2023, the conferences were held every two years, with the first SOSP conference taking place in Gatlinburg, Tennessee. Beginning in 2024, SOSP the conference is held every year.

Type 03 Chū-SAM. The  or SAM-4 or  is a Japanese developed surface-to-air missile system currently in service with the JGSDF. The SAM's vehicle chassis is based on the Kato Works Ltd/Mitsubishi Heavy Industries NK series heavy crane truck. It uses a state-of-the-art active electronically scanned array radar.

Overview
The Chu-SAM air defense system is based on 8×8 cross country unarmored trucks, and includes a command center, radar unit, launcher, and transloader, with each unit equipped with six missiles that travel at Mach 2.5. The system can track up to 100 targets simultaneously and target 12 at the same time, engaging fighter jets, helicopters, and cruise missiles.

Upgrade

Chu-SAM Kai 
In 2014, the JGSDF began evaluation of the upgraded Chu-SAM Kai, which uses improved sensor and networking features for better range and targeting of more complex cruise and anti-surface missile threats.  During the summer of 2015, 10 Chu-SAM Kai missiles were test fired at White Sands Missile Range in the United States and successfully intercepted various targets, including a GQM-163 Coyote supersonic target drone; White Sands hosted the launches because the location's large size and controlled airspace allowed for testing conditions unavailable in Japan. Operational tests of the Chu-SAM Kai took place at White Sands, in 2016.

All procurements are expected to be completed by the FY2032 budget.

Type 23 ship-to-air missile 
The Chu-SAM Kai missile is also planned to be converted to the long-range ship-to-air missile with an ejectable rocket booster. It was successfully test fire onboard JS Asuka in December 2022. The new missile’s main body is based on the technology of the Type 03 medium-range surface-to-air missile (modified), which is currently being deployed by the Japan Ground Self-Defense Force (JGSDF), and the booster is based on the technology of the Type 07 VL-ASROC in service with the JMSDF.

The ship-to-air missile, an upgraded version of the Chu-SAM Kai formerly known as the A-SAM, began procurement in FY2024 as the Type 23 ship-to-air missile.

Chu-SAM Kai (future version)
From FY2023 to FY2028, the Chu-SAM Kai will be upgraded to develop a new missile with enhanced intercept capability against short-range ballistic missiles and hypersonic glide vehicles.

Triphenylmethyl hexafluorophosphate. Triphenylmethyl hexafluorophosphate (also triphenylcarbenium hexafluorophosphate, trityl hexafluorophosphate, or tritylium hexafluorophosphate) is an organic salt with the formula , consisting of the triphenylcarbenium cation  and the hexafluorophosphate anion .

Triphenylmethyl hexafluorophosphate is a brown powder that hydrolyzes readily to triphenylmethanol. It is used as a catalyst and reagent in organic syntheses.

Preparation
Triphenylmethyl hexafluorophosphate can be prepared by combining silver hexafluorophosphate with triphenylmethyl chloride:

A second method involves protonolysis of triphenylmethanol:

Structure and reactions
Triphenylmethyl hexafluorophosphate readily hydrolyzes, in a reaction that is the reverse of one of its syntheses:

Triphenylmethyl hexafluorophosphate has been used for abstracting hydride () from organic compounds. Treatment of metal-alkene and diene complexes one can generate allyl and pentadienyl complexes, respectively.

Triphenylmethyl perchlorate is a common substitute for triphenylmethyl hexafluorophosphate. However, the perchlorate is not used as widely, because, like other organic perchlorates, it is potentially explosive.

Vermont Sustainable Heating Initiative. Vermont Sustainable Heating Initiative (commonly referred to as VSHI) was a non-profit organization that worked to establish sustainability in the Vermont heating sector.  The organization advocated biomass fuels (especially wood pellets) over fossil fuels.  In order to promote sustainability and reduce the expense of home heating for impoverished Vermonters, VSHI installed pellet stoves in low-income houses at no cost. VSHI also advocated for the sustainable development of local biomass sources for fuel.

History
In 2007 a group of students from Mount Abraham Union High School prepared a presentation on the subject of grass energy in Vermont.  This presentation discussed both the environmental and economic impact that grass-derived biomass fuels would have on the Vermont economy. As of 2008 VSHI morphed from a loose coalition of students and educators to a state-registered nonprofit corporation.

In 2009 VSHI prepared a grant proposal in an attempt to obtain $30,000 to fund a feasibility study into solid biomass fuels.  The proposal received support from a number of towns and was approved. As of 2010 VSHI has launched the Chittenden County Solid Biofuels Feasibility Study using the grant money in cooperation with the Chittenden County Regional Planning Comm. and The Biomass Energy Research Center.

In 2016, VSHI was formally dissolved.

Pellet stoves
As part of its regular operations, VSHI works with LIHEAP recipients to place pellet stoves with low-income Vermont households.  VSHI reviews applications from recipients in Addison, Chittenden, and Washington Counties and gives out pellet stoves in the fall accordingly.  A over 20 pellet stoves have been given away to date.  The cooperation with LIHEAP is currently run as a pilot project, but VSHI hopes to expand it in the future.

Virtual USA. Virtual USA (vUSA), is a joint federal and state collaboration on a project that would allow state and local on-line tools and technologies, such as caches of geospatial data, to be interoperable and more useful with the goal of creating a "Virtual USA" for emergency response purposes. The initiative was developed by the DHS Directorate for Science and Technology (S&T), and  currently operates as a pilot in eight states — Alabama, Georgia, Florida, Louisiana, Mississippi, Texas, Virginia and Tennessee — with plans to incorporate additional states.

Virtual USA is part of the DHS' Open Government plan, which is part of the Obama administration's goal to promote a greater amount of transparency and openness between the government and citizens.

Purpose and overview
The stated goal of Virtual USA is to aggregate existing data, from federal, state, local, tribal, and other information into a common operating picture to assist first responders during emergencies.

Virtual USA:
Virtual USA utilizes current information-sharing platforms to permit new and existing technologies to exchange information with one another.
Virtual USA is based on the needs of local and state first responders to manage data access within their own jurisdictions and to share information with relevant jurisdictions across the United States.
Virtual USA is not limited to information exchanges between two agencies; instead, the initiative fosters information sharing among all federal, state, local and tribal authorities.
Virtual USA uses open data standards and open-source software, more states and localities are able to join this information exchange project.
Virtual USA allows Americans in their own communities to contribute information—in real-time to support the efforts of police, fire and emergency management officials during disasters and recovery efforts.

Statistics
In the state of Virginia, Virtual USA has reduced response times to incidents involving hazardous materials by 70 percent.

California Department of Education Headquarters. The California Department of Education Headquarters (CDEH), known also as Block 225, is a component of the Capitol Area East End Complex in Sacramento, CA.  The building achieved a LEED Silver rating in 1999, and later achieved LEED Gold in 2003, only the second LEED Gold building in California at the time.  Following a further cultivation in operations and maintenance, the building eventually achieved a LEED EB Platinum rating, the second largest EB Platinum rating in the world.

Design
Taking the fast track under design-build — the first design-build office building in California's history — Block 225 finished 10 months ahead of the class schedule.  
Designed by Curtis W. Fentress, FAIA, RIBA of Fentress Architects, the CDEH/Block 225 consolidated the headquarters of the Department of Education, which formerly occupied several facilities located throughout Sacramento.  The six-story, 461,000-gross-square-foot building houses offices for the state employees and a nonprofit childcare facility, for a total of about 1,350 occupants.

The building is the largest office campus ever undertaken by the California Department of General Services.  As a result of its extraordinary green qualities and its successful design-build delivery, it has become a benchmark for all future California public projects in this complex and around the State.

Judy Company. Judy Company is a geotechnical engineering firm located in Kansas City, Kansas. It was founded in 1922 by a geological engineer named Philip S. Judy, using the name Air Made Well Company.

History 
Phillip Judy started his professional career as an investigator for Missouri civic engineering projects. He made his reputation by being an early pioneer of foundation consolidation (soil) by pressure grouting.

The company began its reputation as a notable engineering firm when they were contracted to perform the foundation work for Bagnell Dam on the Osage River in central Missouri. Bagnell Dam was completed in 1931 and is one of two operational hydroelectric power plants in the State of Missouri, the other being Taum Sauk Hydroelectric Power Station. Bagnell Dam formed a fresh water reservoir named Lake of the Ozarks, which, at the time, was one of the largest Man-made lakes on the planet. The foundation and dam structure was engineered to retain 646,000,000,000 US gal.

In 1966 the company was incorporated as the Judy Company, Inc.

Technological Developments 
The Judy Company developed "Cell-A-Fill" back fill material. It is a by-product of western coal, and is a self-supporting material that will conform to irregular surfaces without compaction. It is made of water, Class "C" fly ash, and foaming and reactive agents.
