Libreboot. Libreboot (briefly known as GNU Libreboot) is a free and open-source software project based on coreboot, aimed at replacing some of the proprietary BIOS or UEFI firmware on supported X86-64- and AArch64-based computers. Libreboot performs the basic machine setup such as CPU initialization or memory controller initialization necessary to load and run a 32-bit or 64-bit operating system, such as Linux or FreeBSD.

Characteristics
Libreboot is established as a distribution of coreboot, but with some proprietary binary blobs removed from coreboot. Libreboot makes coreboot easy to use by automating the build and installation processes.

On some devices, Libreboot developers have reverse engineered the firmware from Intel and created a utility to create a free firmware that meets the specifications from Intel. Hardware support includes but is not limited to the ASUS KGPE-D16, ThinkPad T400, X60 and X200. Libreboot is officially endorsed by the upstream coreboot project.

History 
The Libreboot project was started in December 2013 as a distribution of coreboot, which excludes non-free binary blobs. Coreboot began as LinuxBIOS in 1999 at Los Alamos National Labs (LANL), and was renamed "coreboot" in 2008.

Libreboot has been endorsed by the Free Software Foundation, and was an official part of the GNU Project since May 2016. In January 2017, the project's maintainer Leah Rowe pulled Libreboot from the GNU Project, after a months-long dispute with the Free Software Foundation which oversees GNU.

Reception 
In 2015, Kyle Rankin stated in Linux Journal that Libreboot "greatly simplified and automated" the flashing process, "with a few caveats". In 2016, Bryan Cockfield stated in Hackaday that Libreboot installation was "harrowing" and "not as easy as you'd think".

Aestus. Aestus is a hypergolic liquid rocket engine used on an upper stage of Ariane 5 family rockets for the orbital insertion. It features unique design of 132 coaxial injection elements causing swirl mixing of the MMH propellants with nitrogen tetroxide oxidizer. The pressure-fed engine allows for multiple re-ignitions.

Operations 
Fuel and oxidizer are stored in two aluminium alloy tanks, fuel tank is spherical while oxidizer tank is enlarged due to different volumes required from engine operations. Before engine is started it is purged with helium and fuel is pressurized. Then oxidizer valve is opened in a center of injector followed by fuel injectors arranged on a chamber wall. Hypergolic propellants spontaneously ignite on contact expanding to supersonic velocities and escaping through cooled nozzle extension.

History 
Aestus was developed by the Ottobrunn Space Propulsion Centre between 1988 and 1995 with first flight as an upper stage of Ariane 5 G flight 502 and performed as designed. The first improvements were developed between 1999 and 2002 improving the frame performance and adjusting propellant mixture ratio from 2.05 to 1.90 with a first flight on an Ariane 5 flight 518 on 26 February 2004. Ignition qualification programme preparing engine for handling new Automated Transfer Vehicle that requires 3 ignitions per flight was completed in 2007 and flew with Jules Verne ATV on Ariane 5 flight 528.

Aestus II / RS-72 
Aestus II (also known as RS-72) was a turbopump-fed version of the pressure-fed Aestus developed in a collaboration between the Ottobrunn Space Propulsion Centre and Pratt & Whitney Rocketdyne (Boeing Rocketdyne at the time). It was designed for improved performance, thrust and reliability over its predecessor.

Aestus II development was supported by Pratt & Whitney Rocketdyne which provided turbopump for the engine. The first prototype variant, called RS-72 Pathfinder, successfully completed 14 tests at the White Sands Test Facility, reaching a 60 second burn time at 100% power in May 2000.

Seibu 9000 series. The  is an electric multiple unit (EMU) train type operated by the private railway operator Seibu Railway on commuter services in the Tokyo area of Japan since 1993.

Design
The 9000 series trains were built between 1993 and 1999 at Seibu's own Tokorozawa Factory by combining electrical equipment from former 101 series EMUs with new steel bodies based on the New 2000 series design. These were the last trains to be built at the Tokorozawa Factory before it closed in 2000.

Fleet
, the fleet consists of eight 10-car sets, numbered 9101 to 9108, based at Musashigaoka depot for use on Seibu Ikebukuro Line workings.

Formations
10-car sets are formed as shown below with six motored ("M") cars and four non-powered trailer ("T") cars.

 Cars 2, 5, and 8 are each equipped with one single-arm pantograph.

Interior
Seating consists of longitudinal bench seating throughout. Wheelchair spaces are provided in cars 2 and 9. Priority seats are provided at the end of each car.

History
The first train entered service in 1993, with eight 10-car sets built by 1999. The fleet was refurbished between 2004 and 2008, with new underframe equipment and VVVF inverter control. Refurbished sets are identified by stickers on the cab end doors.

Tamako Line transfer 

Beginning in 2020, the 9000 series fleet was shortened to four-car formations and modified to accommodate driver-only operation for use on the Tamako Line. The first of these sets was set 9108, which entered service on the Tamako Line on 1 October 2020.  the entire fleet has been modified for Tamako Line operation, excluding sets 9101, 9106, and 9107, which were scrapped beforehand.

Livery variations

"Red Lucky Train"

From July 2014, set 9103 was repainted in a "Red Lucky Train" livery in collaboration with the private railway operator Keikyu. In return, Keikyu painted one of its own N1000 series sets into an all-over yellow livery similar to the Seibu livery in May 2014. Set 9103 was repainted in an all-over red livery after it was modified for Tamako Line operation.

"L-train"

From 17 January 2016, set 9108 operated in a special "L-train" livery consisting of the Saitama Seibu Lions baseball team colour of dark blue with Seibu Lions logos. The set's Seibu Lions logos were removed following its modification for use on the Tamako Line.

"Seibu KPP Train"

From 4 June 2016, set 9101 operated in a special "Seibu KPP Train" pink livery to mark the 100th anniversary of Seibu Railway in 2015 and the fifth anniversary of singer Kyary Pamyu Pamyu. The train operated in this livery until 29 September 2016, after which date the Kyary Pamyu Pamyu vinyls were removed, with the trainset operating in all-over pink livery.

Orchid Graphics Adapter. The Orchid Graphics Adapter is a graphics board for IBM PC compatible computers, released in 1982 by Orchid Technology.

It was intended to provide high resolution (at the time) monochrome graphic abilities to computers limited to text displays. It was aimed at the business market and one of the three first third party graphic boards for PCs (the others being Plantronics Colorplus and Hercules Graphics Card).

It offered a monochrome 720 × 350 pixel resolution (similar to Hercules Graphics Card) and required an existing MDA board to function. The board also offered an IBM PC joystick adapter. 

No software, other than GSX-86 and that supplied with the board (Dr. Halo by Media Cybernetics), offered support for the hardware. Graphic routines could be called from FORTRAN, PASCAL or IBM BASIC.

Output capabilities
720 × 350 monochrome graphics, pixel aspect ratio of 1:1.55.

Thread (network protocol). Thread is an IPv6-based, low-power mesh networking technology for Internet of things (IoT) products. The Thread protocol specification is available at no cost; however, this requires agreement and continued adherence to an end-user license agreement (EULA), which states "Membership in Thread Group is necessary to implement, practice, and ship Thread technology and Thread Group specifications."

Often used as a transport for Matter (the combination being known as Matter over Thread), the protocol has seen increased use for connecting low-power and battery-operated smart-home devices.

Organization 
In July 2014, the Thread Group alliance was formed as an industry group to develop, maintain and drive adoption of Thread as an industry networking standard for IoT applications. Thread Group provides certification for components and products to ensure adherence to the spec. Initial members were ARM Holdings, Big Ass Solutions, NXP Semiconductors/Freescale, Google-subsidiary Nest Labs, OSRAM, Samsung, Silicon Labs, Somfy, Tyco International, Qualcomm, and the Yale lock company. In August 2018, Apple joined the group, and released its first Thread product, the HomePod Mini, in late 2020.

Characteristics 
Thread uses 6LoWPAN, which, in turn, uses the IEEE 802.15.4 wireless protocol with mesh communication (in the 2.4 GHz spectrum), as do Zigbee and other systems.  However, Thread is IP-addressable, with cloud access and AES encryption. A BSD-licensed open-source implementation of Thread called OpenThread is available from and managed by Google.

The OpenThread network simulator, a part of the OpenThread implementation, simulates Thread networks using OpenThread POSIX instances. The simulator utilises discrete-event simulation and allows for visualisation of communications through a web interface.

Use cases 
In 2019, the Connected Home over IP (CHIP) project, subsequently renamed to Matter, led by the Zigbee Alliance, now the Connectivity Standards Alliance (CSA), Google, Amazon, and Apple, announced a broad collaboration to create a royalty-free standard and open-source code base to promote interoperability in home connectivity, leveraging Thread, Wi-Fi, and Bluetooth Low Energy.
