WRPN Calculator. WRPN (or Windows Reverse Polish Notation) is an open-source scientific software calculator, simulating the Hewlett-Packard Voyager series' HP-16C "Computer Scientist" programmable calculator.

History 
On April 3, 1995, Emmet P. Gray, an American programmer, at the time civilian employee at the US Army, now adjunct professor at the Texas A&M University, released WRPN 1.0 (16-bit), a public domain open-source software written in Borland C++ 4.0 for early versions of Microsoft Windows.

As of September 2024 the project is still in active development, and the latest WRPN 7.1.1 was released on August 26, 2024, for modern operating systems with Java installed, and as a mobile application for Android. Source code is available in C#, VB.NET, ASP.NET and Java.

Features 
WRPN simulates almost all of the functions of HP-16C:
 RPN (Reverse Polish notation) input support
 Floating point, Decimal, Hexadecimal, Octal and Binary modes
 Word sizes from 1–64 bits per word
 Signed math
 Logical operators
 Bitwise operators
 32 storage registers
 4 position stack
 203 lines of program memory

JRPN 
In 2019 Bill Foote, an American software engineer and ex-Lead of the Sun Microsystems' standardization of interactive technologies for Blu-ray and other TV platforms, created the JRPN (JOVIAL Reverse Polish Notation Calculators), an open-source HP-16C simulator, forked from WRPN 6.0.2 in Java, but with all of the text set to be rendered from vector fonts (instead of the bitmap font used in WRPN), and licensed it under the free Apache License.

During the COVID-19 pandemic Foote fully rewrote JRPN code in Flutter and licensed it under GPLv3. JRPN is available now in two variants, 15C and 16C (simulating HP-15C and HP-16C accordingly), for Android, Linux, Mac OS, Windows and as a web application.

Also there is another RPN calculator of the same name, developed by William Giel as freeware proprietary software. It has been last released in 1999.

International MV Series. The International MV Series is a medium-duty Class 6/7 truck produced by Navistar International since 2018. Introduced as the successor to the DuraStar, the MV Series is slotted below the International Transtar regional-haul semitractor and above the Class 5 International CV.

Production 

In line with revisions to International Class 8 product lines, the MV Series introduced a number of updates to the cab interior. Externally distinguished by larger doors and side windows, the quarter windows of the DuraStar were replaced with a single-piece side window with a lower windowsill. The dashboard underwent extensive changes, with the previous instrument panel replaced by a reconfigurable digital display.

The International MV Series continues its use of Cummins diesel engines, with the Cummins B6.7 and L9 offered, depending on configuration.

In 2021, the MV Series was updated with a redesigned hood and bumper.

Models 
The MV is available in two models; the MV607 and the MV60H (Lo-Profile). The 607 has an overall height of 67.7 in. and the 60H has an overall height of 62.8 in.

Bus 

The cowled bus chassis variant of the MV was unveiled on July 14, 2023 for the 2025 model year to replace the DuraStar-based International 3300 after 19 years of its production since 2004. The chassis is exclusively bodied by International's subsidiary IC Bus. As of 2025 production, the MV-based bus chassis is available exclusively in diesel and electric powertrain options, dropping the gasoline and propane options from the previous DuraStar-based chassis.

Electric variant (eMV) 
In 2021, Navistar announced a battery electric variant of the MV Series, the eMV. Navistar and Penske both announced on October 11, 2021, that Penske would be the first fleet in the United States to operate the eMV.

Scaled Composites 437. The Scaled Composites Model 437 Vanguard is a stealth demonstration aircraft built by Scaled Composites and Northrop Grumman. Based off the Scaled Composites 401 the model 437 includes manual piloting capabilities and an engine change from the Pratt & Whitney Canada JT15D-5D to the more powerful Pratt & Whitney PW535. It intends to explore the role of a low cost jet aircraft, and demonstrate rapid design techniques as part of Northrop's "Digital Pathfinder" program.

It completed its first flight on August 29, 2024, at Mojave Air and Space Port.

Development
The Model 437 first began as a loyal wingman drone in 2021, based on Scaled Composites earlier Model 401. A key aspect of the program was the exploration of an "attritable aircraft", in which aircraft cost is minimized to effectively provide a semi-expendable package, which can be easily replaced. Crucially, an attritable aircraft does not need to fulfil all aspects of a conventional combat aircraft, but rather acts as a force multiplier for another parent aircraft. In line with this, Northrop proposed that the aircraft cost per unit could be as low as $5-6 million USD if the aircraft was put into serial production.

Development on the Model 437 pioneered the Digital Pathfinder project, in which legacy design technologies were replaced with emerging technologies, overhauling the design process to reduce overall cost and time of development whilst necessitating less reworking. As a result, engineering rework was cut down from 15 to 20% to less than 1%, with the time between commencement of design and first flight only 21 months.

As part of the Digital Pathfinder project, Northrop Grumman used plasma arc directed energy disposition  in the construction of the wing's titanium structural brackets, the first application on a defense aircraft to fly, whilst reducing the need for hard tooling and improving quality. The use of this process reduced cost by 30 percent compared to traditional methods.

Torch Electronics. Torch Electronics is a controversial company based in the United States, primarily engaged in the production and distribution of electronic gaming machines. Torch Electronics has been the subject of various lawsuits and regulatory actions, mainly centered around the legality of its gaming devices.

History 
Torch Electronics was founded in Missouri by Steven Miltenberger, the company's primary business revolves around producing "no chance" gaming machines, which bear a striking resemblance to slot machines. These machines are typically installed in gas stations, convenience stores, and other small venues. Unlike traditional slot machines found in casinos, Torch Electronics markets its devices as skill-based games that do not rely solely on chance, attempting to circumvent the stricter gambling regulations that govern chance-based gaming.

Legal Controversies 

In 2022, Missouri lawmakers renewed their push for stricter regulations to curb the spread of Torch's machines, threatening the loss of liquor licenses for stores hosting Torch's machines. Local casino operators have also expressed concern over Torch's operations, claiming that the company is benefiting from unregulated gambling without paying the taxes and fees typically required of legitimate gaming operators.

Public Perception 
Torch Electronics has drawn criticism from consumer protection advocates, local officials, and gambling industry experts. Opponents argue that the company's machines target vulnerable populations, including individuals with gambling addictions, while operating in an unregulated environment that lacks the safeguards present in licensed casinos. They also argue that the machines siphon revenue away from state-sponsored lotteries and licensed gaming operations, which are typically subject to stricter oversight and taxation.

Supporters of Torch Electronics, on the other hand, claim that the machines offer a form of entertainment and economic opportunity for small businesses with wide adoption seen across Missouri particularly in convenience stores and gas stations. The company itself maintains that it operates within the bounds of state law with its attorney Chuck Hatfield stating that Torch supported ordinances targeting illegal gambling parlors and it's machines are legitimate businesses.

Torch Electronics has reportedly been involved in lobbying efforts to protect its business model and prevent the passage of stricter regulations that would affect its operations. Then Missouri Attorney General Eric Schmitt returned donations from founder Steven Miltenberger and his wife Sondra Miltenberger.

Lawyers under appointed AG Andrew Bailey's attorney general's office withdrew from a lawsuit related to Torch's slot machines with Torch contributing to Bailey's 2024 Missouri Attorney General election campaign.

Bailey's office did not respond to questions as to why Bailey's office chose to accept the money rather than withdraw from the case.

FE-07. The FE-07 (abbreviated from the Spanish: Férreo Español 2007) is a steel-wheeled model of electrical multiple units used on the Mexico City Metro, entering service in 2009 and currently servicing Line A.

Conception 
The trains are powered by an overhead catenary with 750V DC and the power supply is by means of a pantograph mechanism, with a carbon friction skate. The metal wheels, made of forged steel, perform the same guiding function and transmit the traction-braking forces.

Each car is supported by two bogies or railroad-type trolleys, each consisting of two axles at the ends of which two metal wheels are fixed, which roll on railroad-type metal rails. The wheels, in addition to supporting the load of the vehicle, serve to guide the trains as well as for their movement.

The train has a disc brake system on each axle, on both sides of the disc there are semi-metallic brake linings (chemical compound), the braking works based on compressed air.

The power supply to the driving cars is carried out through the pantograph (equipment mounted on the roof of the cars that has an upward and downward movement) which remains in contact during the movement of the trains with the contact wire of the compound catenary (this is a power supply system, whose function is to provide electric power to moving trains, it is made up of 7 wires attached to pendulums and harnesses that allow its attachment to poles along the Line).

This train was acquired in response to the fact that the FM-95As were spending more time in the workshops than in service and the lack of spare parts for them, in addition to serving as a support for the FM-86s that would have carried the entire load due to the decommissioning of almost the entire FM-95A fleet.

The driving train FM-0083/FM-0084 suffered a derailment, but the insurance policy took care of putting the train back into operation.

It is worth noting that this accident occurred in 2016.

Description 
The FE–07 currently services Line A only. Each train is equipped with alarm levers, ATP-ATO automatic driving system, passenger information and video entertainment systems, CCTV, and saloon and cab ventilation systems. This is the first steel-wheeled rolling stock in the metro network to feature open gangways, allowing passengers to move seamlessly between train cars, the first overall train to have this feature was the NM-02.

The entire length of a train is .

Interior side coverings, side hatches and roofs made of fibreglass-reinforced polyester. Passenger seats in SMC.

OpenGeofiction. OpenGeofiction (abbreviated OGF) is an online collaborative mapping project focused on fantasy cartography and worldbuilding of a world analogous to Earth. It uses OpenStreetMap software and processes in a separate environment, providing an outlet for artistic expression that avoids interfering with OpenStreetMap's mapping of the real world and potentially mitigates the risk of vandalism there.

History 
OpenGeofiction was founded in September 2013 by the German software developer Thilo Stapff and urban planner Johannes Bouchain.

Content 
OpenGeofiction portrays a verisimilar world based on modern technology but fictitious geography and culture. Both the natural and built environment are represented. The map tiles produced by the project are in Web Mercator projection.

Participation 
OpenGeofiction allows anyone with a free account to contribute directly to the map through an editor such as the iD Web application or the JOSM desktop application. Contributors can focus on various aspects of worldbuilding, including urban design and transportation. Because the project maintains a single integrated fictional world, contributors must harmonize their fictional territories with neighboring territories. Thousands of users have contributed to the project.

Uses 
Places can be mapped in OpenGeofiction to illustrate stories or establish scenes for role-playing games. OpenGeofiction map tiles can be loaded into applications such as gvSIG for geospatial analysis. In 2018, OpenGeofiction data was used to model urban population movements in a hypothetical emergency evacuation using argument technology.

No. 21 Squadron PAF. The No. 21 Air Mobility Squadron also known by its nickname the Globe Trotters is a transport unit of the Pakistan Air Force's 40th Air Mobility Wing. The squadron is based at PAF Base Faisal and operates Lockheed C-130 Hercules and Saab-2000s.

History 
The 21 AM Squadron was originally established as a detachment of the 6 Squadron at PAF Base Faisal. Equipped with a few C-130s, the detachment was assigned the prime responsibility to provide airlift/air transport services to the Pakistan Armed Forces in the southern regions of Pakistan specifically to units along the coastal belt along the Arabian Sea. The detachment was re-established as the No. 21 Air Transport Squadron (ATS) in July 2008 retaining its previous role. The squadron's fleet was enlarged with the acquisitions of Saab-2000 airliners in 2014. These SAABs were later locally modified to carry FLIR seekers for undertaking of Intelligence, Surveillance and Reconnaissance (ISR) missions. In January 2022, the squadron was renamed as the No. 21 Air Mobility (AM) Squadron.

Operational history 
Over the years, the No. 21 AM squadron has carried out several humanitarian support missions around the world in collaboration with NGOs and government organizations like the NDMA.

The squadron took part in relief support operations for IDPs of the Swat conflict. Moreover, it carried out flood relief ops in southern Pakistan during the 2010, 2011 and 2012 floods at Nawabshah, Mirpur Khas, Sukkur and Jacobabad.

During the 2011 Japan Earthquake, the squadron's C-130s airlifted several tons worth relief goods to Japan. The same year, 94,000lbs humanitarian aid was airlifted to affected areas in Baluchistan within a span of 4 days.

The squadron remained actively involved in supporting roles during the launching phases of Operation Zarb-e-Azb and Giyari Operation while also holding an important role in supporting deployments of various armed forces units to their wartime locations most notably during Operation Swift Retort.

After the COVID-19 Pandemic, the squadron carried out worldwide air mobility operations in support of PIA to transport Pakistani nationals stuck in various countries after international flights were halted. In the first mission, pilgrims stuck in Dalbandin were transported to Skardu.
