Paessler PRTG. PRTG (Paessler Router Traffic Grapher ) is a network monitoring software developed by Paessler GmbH. It monitors system conditions like bandwidth usage or uptime and collect statistics from miscellaneous hosts such as switches, routers, servers, and other devices and applications.

It was initially released on May 29, 2003 by the German company Paessler GmbH which was founded by Dirk Paessler in 2001. 

The software is available in three versions: a classic standalone solution (PRTG Network Monitor), one for large and distributed networks (PRTG Enterprise Monitor) and a SaaS-version (PRTG Hosted Monitor).

Specifications
The software has an auto-discovery mode that scans predefined areas of an enterprise network and creates a device list from this data. Further information on the detected devices can be retrieved using communication protocols like ICMP, SNMP, WMI, NetFlow, jFlow, sFlow, DCOM or the RESTful API.

Sensors
The software is based on sensors, e.g. HTTP, SMTP/POP3 (e-mail) application sensors and hardware-specific sensors for switches, routers and servers. The software has over 200 different predefined sensors that retrieve statistics from the monitored instances, e.g. response times, processor, memory, database information, temperature or system status.

Web interface and desktop client
The software can be operated via an AJAX-based web interface which is suitable for both real-time troubleshooting and data exchange with non-technical staff via maps (dashboards) and user-defined reports. An additional administration interface in the form of a desktop application for Windows, Linux, and macOS is available.

Notifications, reports and price model
In addition to the usual communication channels such as Email and SMS, notification is also provided via an app for iOS or Android. The software also provides customizable reports and its price model is based on sensors.

Narrow gauge railway at Camp A. A. Humphreys. The narrow gauge railway at Camp A. A. Humphreys was a  long  gauge military railway at what is now Fort Belvoir, Virginia .

History 
In 1918, the AA Humphreys camp was set-up in Fort Belvoir, Virginia. It was named after Brigadier General Andrew Atkinson Humphreys, who served during the civil war in the Union Army and later as the Chief of the engineers of the army before he died in 1883. It was an important training camp for pioneers and other soldiers who learned to build roads, railroads, bridges and trenches.

Beginning in the first half of 1918, a  long narrow gauge line was built there.  of track ran between the pier at the Potomac River and Camp Humphreys.

The light rails of a narrow-gauge railway could be laid quickly and, if necessary, quickly dismantled. The  long prefabricated sections of the flying track weighing  could be carried and laid by only two soldiers. Because of the small gauge, smaller radii could be used than with standard gauge railways.

From March 1918 until the end of the war on 11 November 1918, hundreds of soldiers and engineers learned how to construct and operate a narrow-gauge railway. They trained to lay tracks, to build railway bridges and to operate the small steam and gasoline locomotives. Many narrow-gauge railways were used by American troops in the international war theater to transport supplies, ammunition and building materials as well as casualties and the wounded. Similar narrow gauge railways were located in Fort Benning, Georgia, Fort Sill, Oklahoma, Fort Benjamin Harrison, Indiana, and Fort Dix, New Jersey.

Around 1920, the narrow gauge railway tracks of Camp Humphreys were lifted and fell into oblivion. After the war, some of the locomotives and wagons of Camp Humphreys and other forts were re-used in mining operations and plantations around the world rather than being scrapped.

OS/7. OS/7 is a discontinued operating system from Sperry Univac for its 90/60 and 90/70 computer systems. The system was first announced in November 1971 for Univac's 9700 system and was originally scheduled for delivery in March 1973. However, the delivery slipped by nearly a year, which impacted the 9700 marketing effort. It was first demonstrated by Univac on the new 90/60 system in October 1973. The official release was then planned for January 1974. OS/7 was abruptly discontinued in 1975 in favor of VS/9, Univac's name for RCA's VMOS operating system.

"OS/7 is a multi-tasking, multi-programming system that utilizes a roll-in, roll-out capability to keep the CPU optimally busy."

Orbital Reflector. Orbital Reflector is a reflective, mylar sculpture by Trevor Paglen launched into space as a temporary satellite. Co-produced by the Nevada Museum of Art, the $1.3 million project had the objective of being the first "purely artistic" object in space. The satellite, containing an inflatable mylar balloon with reflective surface, launched into space 3 December 2018.

Orbital Reflector launched on Monday, December 3, at 10:34 a.m. EST on board the SpaceX Spaceflight SSO-A: SmallSat Express.

Originally it was expected to remain in orbit for three months, after which it would disintegrate upon reentry to the Earth's atmosphere. However, the deployment was delayed by the 2018–2019 United States federal government shutdown — by the time the 35-day shutdown had ended, the museum's engineers had lost contact with the satellite, the electronics and hardware of which "were not hardened for long-term functionality in space".

It became lost in orbit, constituting space junk.

Forsyth Water Pumping Station. The Forsyth Water Pumping Station, on 3rd Ave. at the Yellowstone River in Forsyth, Montana, was built in 1907–1908.  It was listed on the National Register of Historic Places in 1990.

It was built by the Des Moines Bridge Building Company as part of the first waterworks and sewer system in Forsyth, funded by a 1906 bond of $50,000.  The pumphouse brought water up from the Yellowstone River to seepage areas where sediment settled out of the water.  The water served the town until 1931 when a more sophisticated waterworks system was opened.

It was deemed "significant as the last surviving remnant of Forsyth's earliest publicly-financed public works project. In turn, the early water system of which this was a part was an important reason behind the incorporation of the community of Forsyth. Its presence served as both a reflection of evolving technology and community standards, and a strengthened community faith in the town's stability and future. The building's design, simple and solid, is a good example of largely unadorned early twentieth-century industrial architecture. Its brick construction, locally unusual, is an indication of the substantive nature of Forsyth's first waterworks project."

2N696. The 2N696 and 2N697 were the first silicon transistors manufactured in Silicon Valley, in 1958, by Fairchild Semiconductor. Fairchild introduced itself to the world via its advertisements for these transistors, which were identical except for a post-manufacturing binning on current gain.

The 2N696/2N697 NPN mesa transistor was developed by a team led by Gordon Moore. The first batch of 100 was sold to IBM for $150 each () in order to build the computer for the B-70 bomber. More transistors were sold to Autonetics to build the guidance system for the Minuteman ballistic missile.

The 2N696 and 2N697 were popular devices, quickly copied by several other semiconductor companies, including Texas Instruments,  Rheem Semiconductor, and others including Hoffman Electronics Corp. and Industro Transistor Corp.  In a 1960 advertisement, Fairchild bragged, "The Fairchild 2N696 and 2N697 are the world's most copied transistors. We have now copied them ourselves in scaled down versions. The 2N717 and 2N718 are exactly the same as these popular types but packaged in the TO-18 case. They occupy 1/3 the volume of the standard TO-5, making them ideal for high-density equipment designs."
