Oklahoma State Cowboys basketball team plane crash. The Oklahoma State University Cowboys basketball team plane crash occurred on January 27, 2001, at 19:37 EST, when a Beechcraft Super King Air 200, registration N81PF, carrying two players on the Oklahoma State Cowboys basketball team along with six Oklahoma State broadcasters and members of the Oklahoma State coaching staff, crashed in a field  east of Denver, near Strasburg, in the U.S. state of Colorado. The pilot had likely become disoriented, caused by equipment and instrument failure during snow storm. The plane was flying from Jefferson County Airport to Stillwater Regional Airport after the team's loss to the Colorado Buffaloes.  

The aircraft was carrying two crew members (pilot Denver Mills, and co-pilot Bjorn Fahlstrom) and eight passengers involved with Oklahoma State basketball. All ten died. Oklahoma State has a memorial erected to them, entitled "Remember the Ten", inside Gallagher-Iba Arena in Stillwater, Oklahoma.

TeST TST-1 Alpin. The TeST TST-1 Alpin () is a Czech shoulder-wing, single-seat, pusher configuration motor glider that was designed and produced by TeST.

Design and development
The TST-1 was the first motor glider in a long line of aircraft produced by the company. The design goals included that it should be economical to build and operate as well as easy to fly, with outstanding soaring capabilities with the engine shut down.

The aircraft has a wooden structure, with some fibreglass parts. The  span wing employs a Wortmann FX 61-184 airfoil. Both the wings and tail detached for transport or storage. The standard engine is a custom M-115 flat configuration two-stroke powerplant of , although other engines can be used instead, including the  Hirth F-23 and  Rotax 447. The engine is mounted in pusher configuration in a faired pod on a short non-retractable strut, above and behind the cockpit. The landing gear is a rigidly-mounted monowheel gear.

When it was available the aircraft was available as plans, a standard 600 hour build-time kit, an "express-built" kit or as a complete ready-to-fly aircraft. Prices in 1998 were US$325 for the plans, US$9,840 for the standard kit and US$15,250 for the completed aircraft. In 1998 22 were reportedly flying.

Helios House. The Helios House is a gas station in Los Angeles, California, United States, located on Olympic Boulevard. It is designed as a green station with special features and is considered to be the "station of the future." It is the first gas station in the world ever to be submitted for LEED certification.

The gas station was designed by Office dA (Principal architects Monica Ponce de Leon and Nader Tehrani) in Boston and Johnston Marklee Architects in Los Angeles.  The architects were hired by Ogilvy & Mather, led by Brian Collins. The lead on this project was Ann Hand, and the purpose of the design was to reinvent the gas stations.

The station's roof is designed of triangles made from recycled stainless steel and contains cacti and 90 solar panels. This reduces the energy consumption of the station by 16%. The station's roof is drought tolerant and collects water for irrigation. The station replaced a run-down Thrifty gas station that previously occupied the site.

Built in 2007, it is seen as a Los Angeles landmark. It started out selling BP branded gasoline (at the time, the only BP branded station in the West Coast), but in 2009 switched to its more prominent West Coast sister brand (at the time) ARCO. As of 2021, it is a Speedway Express, a gas station-only brand of the Speedway chain, which, in turn, was a former subsidiary of Marathon Petroleum, ARCO's current parent company, and now a subsidiary of Seven & I Holdings, parent company of 7-Eleven.

Features of the station

Structural
 Made of cradle to cradle recyclable stainless steel
 Farmed wood facade

South African Class MJ1 2-6-6-0. The South African Railways Class MJ1 2-6-6-0 of 1918 was a class of articulated steam locomotives.

In 1918, the South African Railways placed eight Class MJ1 Mallet articulated compound steam locomotives with a 2-6-6-0 wheel arrangement in branch line service.

Manufacturer
Because of the difficulties experienced by the usual British and German suppliers to build new locomotives during the First World War, orders for the Class MJ1 2-6-6-0 Mallet articulated compound steam locomotive were placed with Montreal Locomotive Works (MLW) in Canada. The locomotive was designed by MLW, based on the specifications for the Class MJ Mallet which had been designed by D.A. Hendrie, the Chief Mechanical Engineer (CME) of the South African Railways (SAR) from 1910 to 1922. Eight of these branch line locomotives were built and delivered by MLW in November 1918, numbered in the range from 1666 to 1673.

Characteristics
The locomotives were superheated, had Walschaerts valve gear and, like the Class MJ Mallets, had Belpaire fireboxes, but slightly larger boilers. When compared to the Class MJ, a distinguishing feature of the Class MJ1 was the sandbox which was mounted on top of the boiler to the rear of the steam dome in North American style. In general appearance, they bore a family resemblance to the Class 14C and Class 15B 4-8-2 locomotives which were also built by MLW in 1918.

During 1922, the coupled wheels were retyred and their diameter was increased from  to .

Reboilering
During 1939, while W.A.J. Day was the CME of the SAR, the Classes MJ and MJ1 were modified slightly to be reboilered with the same standard boiler.

Service
The Class MJ1 was the last Mallet locomotive class to be placed in service by the SAR. All the Railway’s subsequent new articulated locomotives were to be Garratts, Modified Fairlies and Union Garratts.

The Class MJ1 was also intended for branch line working and joined the Class MJ Mallets in service in the Eastern Cape. All eight were still in service by March 1948, but they were all withdrawn from service by 1960.

NASA Hyper III. 

The NASA Hyper III was an American unpowered full-scale lifting body remotely piloted vehicle designed and built at the NASA Flight Research Center at Edwards Air Force Base, California.

Design and development
The Hyper III was designed to help in the M2 lifting body program, it had a flat bottom and sides, and a simple straight wing with no control surfaces that was designed to simulate a pop-out wing that had been proposed for a re-entry vehicle. The Hyper III had twin fins and rudders canted at 40° from the vertical, and hinged elevons on the horizontal surface. The landing gear was a fixed tricycle type, using spring steel legs from a Cessna aircraft. It was fitted with an emergency parachute system and controlled by 5-channel radio link; instrument data was downlinked using a 12-channel radio.

On 12 December 1969 the Hyper III was launched from a helicopter at 10,000 feet. It glided 5 km, turned round, came back and landed. After the three-minute flight it was not flown again as the Center cancelled the program.

Lennart Poettering. Lennart Poettering (born 15 October 1980) is a German software engineer working for Microsoft and the original author of PulseAudio, Avahi and systemd.

Life and career 

Poettering was born in Guatemala City but grew up in Rio de Janeiro, Brazil, and Hamburg, Germany. Poettering worked for Red Hat from 2008 to 2022. He then joined Microsoft.

Since 2003, Poettering has worked on more than 40 projects, mostly written in C. He is the developer and maintainer of several free software projects which have been widely adopted by Linux distributions, including PulseAudio sound server (2004), Avahi zeroconf implementation (2005), and systemd init system (2010).

Controversies 

Poettering is known for having controversial technical and architectural positions regarding the Linux ecosystem.

His style has brought accusations that he is working against long-standing Unix philosophy, which he addressed in his blog post The Biggest Myths. For instance, Poettering has advocated speeding up Linux development at the expense of breaking compatibility with POSIX and other Unix-like operating systems such as the BSDs. He took this position because of his experience in writing some other low-level components in the desktop stack. He invites other developers to do the same. Poettering recommends also reading The Linux Programming Interface but ignoring the POSIX-specific parts.

In 2011 Poettering, one of the main developers of PulseAudio, praised the Windows and macOS audio stacks as "more advanced" and called Open Sound System "a simplistic 90's style audio stack" without relevance for a modern desktop.

Also in 2011, when asked why the Linux desktop hadn't been widely adopted by mainstream users, he answered that: "Linux is still too fragmented...[and] needs to be streamlined...". In 2014 Poettering published an essay criticising how software in Linux distros is commonly packaged, updated, and deployed; and laid out proposals that he, Kay Sievers, Harald Hoyer, Daniel Mack, Tom Gundersen and David Herrmann, had for how the architecture should be changed.

The controversy around systemd culminated in personal attacks and alleged death threats against Poettering. Poettering went on to put some blame on Linus Torvalds and other kernel developers for being bad role models for encouraging an abusive discussion culture on technical disagreements.

In 2017, Poettering received the Pwnie Award for Lamest Vendor Response to vulnerabilities reported in systemd.

Modular Equipment Transporter. The Modular Equipment Transporter (MET) was a two-wheeled, hand-pulled vehicle that was used as an equipment hauling device on traverses across the lunar surface. Designed after Apollo 12 astronauts Pete Conrad and Alan Bean had difficulties lugging their equipment significant distances to and from their Lunar Module,  the MET primarily functioned as a portable workbench with a place for hand tools and their carrier, cameras, spare camera magazines, rock sample bags, environmental sample containers, and the portable magnetometer with its sensor and tripod. It was carried on the 1971 Apollo 14 mission and was planned to be used on Apollo 15, but was used only on Apollo 14 since Apollo 15's mission was changed to be the first to employ the motorized Lunar Roving Vehicle, which transported both astronauts and equipment.

Astronauts nicknamed the MET "the rickshaw".  It was pulled using a pulling bar at the front.  The majority of the payload of the MET consisted of part of the Apollo Lunar Surface Experiments Package (ALSEP)., including a portable magnetometer, as well as various tools and space to transport samples. The performance of the MET was described as "adequate". In fact, astronauts Alan Shepard and Edgar Mitchell were disappointed by the MET's performance. During one of the traverses they had to carry the MET together because it was too difficult to pull it through the rough lunar terrain.

The two nitrogen-filled rubber tires on the MET were the first tires on the Moon. They were designed by Goodyear Tire and Rubber Company and called Experimental Lunar Tires (XLTs). The biggest challenge for Goodyear was that NASA specifications required the inner tube be inflated to 1.5 psi on the Moon surface; a difficult task. A tire with 1.5 psi on Earth has an inflation pressure of 16.2 psi on the Moon because atmospheric pressure (14.7 psi) is not a factor there. Goodyear solved the gauge pressure problem by having NASA partially inflate the inner tube with nitrogen so that on the Moon it reached 1.5 psi. The tire maker gave the synthetic rubber tube a special coating to improve gas retention. These tires worked well for the small MET rickshaw. The later Lunar Roving Vehicle demanded wheels or tires that could handle a much greater weight and could travel much farther than the MET. NASA went with General Motors and they designed a wire-mesh wheel that didn't allow lunar dust to get stuck in the wheels.

Network Policy Server. Network Policy and Access Services (NPAS) is a component of Windows Server 2008. It replaces the Internet Authentication Service (IAS) from Windows Server 2003. The NPAS server role includes Network Policy Server (NPS), Health Registration Authority (HRA), and Host Credential Authorization Protocol (HCAP). In Windows Server 2003, IAS is the Microsoft implementation of a Remote Authentication Dial-In User Service (RADIUS) server. In Windows Server operating systems later than Windows Server 2003, IAS is renamed to NPS.

Overview 
NPS is a role service in Windows Server 2008 which can function as:
 RADIUS server
 RADIUS proxy
 Network Access Protection policy server

Features 
NPSEE enables the use of a heterogeneous set of wireless, switch, remote access, or VPN equipment. One can use NPS with the Routing and Remote Access service, which is available in Microsoft Windows 2000, Windows Server 2003, Standard Edition; Windows Server 2003, Enterprise Edition; and Windows Server 2003, Datacenter Edition.

When a server running NPS is a member of an Active Directory Domain Services (AD DS) domain, NPS uses the directory service as its user account database and is part of a single sign-on solution. The same set of credentials is used for network access control (authenticating and authorizing access to a network) and to log on to an AD DS domain.

Platform engineering. Platform engineering is a software engineering discipline focused on the development of self-service toolchains, services, and processes to create an internal developer platform (IDP). The shared IDP can be utilized by software development teams, enabling them to innovate.

Platform engineering uses components like configuration management, infrastructure orchestration, and role-based access control to improve reliability. The discipline is associated with DevOps and platform as a service practices.

Purpose & Impact 
Platform engineering aims to improve software engineering productivity by creating streamlined toolchains that can be used by developers. It can be used for digital transformation, or to expand CI/CD setups.

According to a panel of experts at PlatformCon 2024, it was stated that building an internal developer platform can improve more than just developer productivity. Platform engineering, which centralizes best practices and components for development teams, is gaining prominence as DevSecOps practices and frameworks become increasingly embedded across organizations. Platform engineering aims to normalize and standardize developer workflows by providing developers with optimized “golden paths” for most of their workloads and flexibility to define exceptions for the rest. Organizations can follow one of two paths when developing a new platform engineering initiative. One option is to build an authentication and visualization layer that sits across multiple point tools — but this does not solve the underlying problems of legacy technology stacks and tooling silos. Therefore, this would likely not be a long-term solution. Alternatively, the organization could implement an internal developer platform (IDP) that reduces the cognitive load on developers by bringing multiple technologies and tools into a single self-service experience.

Platform engineering’s benefits include faster time to market, reduced security and compliance risk, and improved developer experience. Establishing a product-oriented culture and setting clear business goals are critical for success in platform engineering. Therefore it can be stated that platform engineering has increased importance wherever businesses strive to do more with less.

Criticism of Platform Engineering 

Despite its benefits, platform engineering faces several criticisms. One major concern is the complexity and overhead associated with building and maintaining such platforms. Additionally, creating a one-size-fits-all platform might not address the unique needs of all development teams, leading to inefficiencies and frustration. Siloed teams and a lack of focus on resolving operational issues can also hinder the effectiveness of the platforms created.

Camera, hand lens, and microscope probe. Camera, hand lens, and microscope probe (CHAMP) is a microscope capable of color imaging with a spatial resolution ranging from infinity imaging down to 3 μm per pixel. The instrument was originally developed through the Mars Instrument Development Program (MIDP) in support of robotic field investigations, and was an instrument proposed for use on the 2011 Mars Science Laboratory rover mission to Mars. The instrument would allow examination of Martian surface features and materials (terrain, rocks, soils, samples) on spatial scales ranging from kilometers to micrometers, thus enabling both microscopy and context imaging with high operational flexibility. The instrument would allow for a better understanding of the evolution of the Martian surface over time. More specifically CHAMP would help gather data for a potential habitat for life on Mars.
