Sun Management Center. Sun Management Center (Sun MC) is a systems management and monitoring tool developed by Sun Microsystems for enterprise-wide management of Sun servers, desktops and storage devices. 
 
It is designed to enhance system performance, reliability, security, and utilization by allowing system administrators to monitor all servers and components in their data center, including boards, CPUs, fans, and power supplies.

The tool comprises three layers. The console, a user interface, interacts with the server to get the configuration information, data, and image files necessary to present views of the managed servers. The server acts as a request broker between the managed systems and the console, handling tasks like topology management, event management, configuration management, and trap handling. An agent normally runs on each system being managed. Each agent has modules capable of managing specific data items, such as hardware, operating system, and application data.

Sun MC provides in-depth monitoring of Sun hardware and a comprehensive set of metrics for the Solaris Operating System, including support for Solaris Containers. It is open and extensible, and supports various add-ons for additional system management capabilities.

Sun MC was originally named Sun Enterprise SyMON, and was co-developed by Halcyon Monitoring Solutions.  Clients are available for Solaris on SPARC and x86 systems as well as Linux on x86 systems.

Protocols used
 SNMP v2usec (optional encryption libraries), v1 and v3 (compatible)

NP-40. NP-40 (also known as Tergitol-type NP-40 and nonyl phenoxypolyethoxylethanol) is a commercially available detergent with CAS Registry Number 9016-45-9.  NP-40 is an ethoxylated nonylphenol for non-ionic surfactants and can act as emulsifier and demulsifier agent.

NP-40 is often used to break open all membranes within a cell, including the nuclear membrane . To break only the cytoplasmic membrane, other detergents such as digitonin can be used. 

NP-40 has applications in paper and textile processing, in paints and coatings, and in agrochemical manufacturing.

Care should be taken to avoid confusing NP-40 with Nonidet P-40 (octyl phenoxypolyethoxylethanol) which is currently out of production. Nonidet P-40 ("Non-Ionic Detergent") was originally manufactured and trademarked by the Shell Chemical Company, but was phased out of production in the early 2000s. Confusingly, biochemical protocols published between the 1960s and 2000s refer to Shell's Nonidet P-40 as NP-40. Shell's original Nonidet P-40 had a hydrophilic-lipophilic balance (HLB) value of 13.5, as opposed to 12.9 for the currently available IGEPAL CA-630, indicating that the currently available compound is more potent than the compound used in older publications. Indeed, according to a 2017 report, an additional dilution factor of 10 was required for the currently available NP-40 ("Nonidet P-40 substitutes") to match the activity of the previously available, and now discontinued, Shell's Nonidet P-40.

B5000 instruction set. The Burroughs B5000 was the first stack machine and also the first computer with a segmented virtual memory.
The Burroughs B5000 instruction set includes the set of valid operations for the B5000, B5500 and B5700. It is not compatible with the B6500, B7500, B8500 or their successors.

Instruction streams on a B5000 contain 12-bit syllables, four to a word. The architecture has two modes, Word Mode and Character Mode, and each has a separate repertoire of syllables. A processor may be either Control State or Normal State, and certain syllables are only permissible in Control State. The architecture does not provide for addressing registers or storage directly; all references are through the 1024 word Program Reference Table (PRT), current code segment, marked locations within the stack or to the A and B registers holding the top two locations on the stack. Burroughs numbers bits in a syllable from 0 (high bit) to 11 (low bit) and in a word from 0 (high bit) to 47 (low bit).

Word Mode

In Word Mode, there are four types of syllables.

The interpretation of the 10-bit relative address in Operand Call and Descriptor Call depends on the setting of several processor flags. For main programs (SALF off) it is always an offset into the Program Reference Table (PRT).

Sodium dimethyldithiocarbamate. Sodium dimethyldithiocarbamate is the organosulfur compound with the formula . It is one of the simplest organic dithiocarbamates.  It is a white or pale yellow, water soluble solid.  The compound is a precursor to fungicides and rubber chemicals.

Preparation
Sodium dimethyldithiocarbamate typically crystallizes from water as the diihydrate NaS2CN(CH3)2.2H2O.  The anhydrous salt and the trihydrate are often used interchangeably.

Sodium dimethyldithiocarbamate is obtained by treating carbon disulfide with dimethylamine in the presence of sodium hydroxide:
CS2  +  HN(CH3)2  +  NaOH   →  NaS2CN(CH3)2  +  H2O
Other dithiocarbamates can be prepared similarly from secondary amines and carbon disulfide.  They are used as chelating agents for transition metal ions and as precursors to herbicides and vulcanization reagents.

Uses

It is a component of various pesticides and rubber chemicals in the form of its salts. Well established derivatives include potassium dimethyldithiocarbamate) as well as its complexes zinc dimethyldithiocarbamate, ferric dimethyldithiocarbamate, and nickel bis(dimethyldithiocarbamate).  Oxidation gives thiram.

M1127 reconnaissance vehicle. The M1127 reconnaissance vehicle (RV) is a wheeled armored personnel carrier in the Stryker family, developed and produced by General Dynamics Land Systems Canada (GDLS-C) and is currently in service with the US Army.

General
The RV provides an effective platform for RSTA squadrons and battalion scouts to perform reconnaissance and surveillance operations. The RV accommodates seven personnel, including crew.

The platform is a key enabler for both sensor and HUMINT focused surveillance and intelligence operations.

The recce troop is organized into a headquarters section, a mortar section, and three recce platoons. Each of the recce platoons is organized with four Stryker reconnaissance vehicles, mounting either a 12.7 mm M2 .50 cal or a Mk 19 40 mm grenade launcher; the lead truck mounts a long range advanced scout surveillance system alongside its main weapon. Each vehicle carries a squad consisting of a 3-man vehicle crew and a 4-man scout squad for dismounted reconnaissance (6-man squad if augmented with linguist). Each recce squad in the platoon has assigned a human intelligence collector (35M HUMINT). The mortar section consists of four 120-mm self-propelled mortars (Stryker variant) and a fire direction center.

Operational capabilities
The MAV reconnaissance vehicle is based on the ICV variant. The reconnaissance vehicle is based on the ICV platform due to the close parallels of operational requirements and battlefield capabilities between the two systems. The reconnaissance vehicle is an organic vehicle to the ICV maneuver formation and helps maximize the commonality of the platform, while simultaneously reducing the maintenance footprint and variety of logistics support.

John Charles Melliss. John Charles Melliss (23 January 1835 – 23 August 1910) was a British engineer and amateur naturalist. He lived in St. Helena and wrote a book on the geology, history and geography of the island in 1875.  He also wrote on the natural history of the island. J.D. Hooker named the genus Mellissia in his honour.

Biography

Melliss was born on the island of St Helena in the South Atlantic Ocean. His father, Captain W. J. Melliss, was an officer of the St Helena Artillery. After training as an engineer at King's College, and serving as an officer in the Royal Engineers, he was appointed successor to his father as Commissioner and Surveyor Engineer of St. Helena from 1860 to 1871. In 1870 he planned a tunnel through Mundens Hill connecting James Valley with Ruperts Valley but this never happened. In 1871, because of government cutbacks, he was made redundant and returned to London, where he subsequently formed the firm of J.C. Melliss and Co. He worked on the drainage of the Lower Thames Valley and the Coventry and Leyton sewage works.

In 1875, he published the book for which he is best known: St. Helena: A Physical, Historical and Topographical Description of the Island, Including the Geology, Fauna, Flora and Meteorology. It was illustrated by his wife, Alice Elizabeth Louisa Melliss, née Stace, who was credited on the title page as "Mrs. J. C. Melliss", and on plates as "A. Melliss".

To commemorate the book's centenary in 1975, the St. Helena Post Office published a set of four stamps, using illustrations from the book.Melliss inspired Thomas Vernon Wollaston, a noted beetle specialist, to visit St Helena with his wife Edith in 1875-76. Wollaston studied the beetles in Coleoptera Sanctæ-Helenæ (1875) while his wife wrote an account of the moths of the island.

Melliss died at his Hampstead home on 23rd August 1910.

Recognition 
Joseph Dalton Hooker named the monotypic plant genus Mellissia in his honour for the plant Mellissia begoniifolia, the St Helena Boxwood. It was subsequently subsumed into the genus Withania.

The Silver Eel (Ariosoma mellissii), also known as the Melliss's Conger was named for him by Albert Gunther.

Family

The Melliss's son, Hugh John Melliss, born in 1880 joined his father's company (later named Melliss and Partners following a partnership with H.R. Smart). He worked for the company until 1955.
