EKA1. EKA1 (EPOC Kernel Architecture 1) is the first-generation kernel for the operating system Symbian OS. EKA1 originated in the earlier 32-bit operating system EPOC. It offers preemptive computer multitasking and memory protection, but no real-time computing guarantees, and a single-threaded device driver model. EKA1 was replaced by EKA2 as the default kernel starting with Symbian v9.

Much of EKA1 was developed by a single software engineer, Colly Myers, when he was working for Psion Software in the early 1990s. Myers went on to act as CEO for Symbian Ltd., when it was formed to license this kernel and associated operating system to mobile phone makers.

Aerial Assault. Aerial Assault is a side-scrolling shooter video game published by Sega for the Master System in 1990 and Game Gear in 1992.

Gameplay
The player takes the role of a Freedom Fighter who must destroy five targets, including the Vinsk (a flying battleship in the Game Gear version, an ordinary ship in the Master System), the CB-53 Bomber, "El", and two cliff fortresses. During each of the five missions, the player encounters enemy jets, choppers, submarines, jeeps, parachute bombs, and several other enemies which they must destroy. Shooting either the spinning fighters, the small flying helicopters, or the mines on the final mission will earn the player a power-up that allows them to upgrade or downgrade their firepower. There are three difficulty settings: "Easy", "Normal", and "Hard". Players will not be able to complete the game if they select the "Easy" setting.

Plot
A militaristic organisation called the N.A.C. developed a huge laser emitter, "EL", which is capable of gradually destroying the ozone layer over the course of a decade or so. In the year 1999, the N.A.C. begins an all-out offensive against every country in the world. The nations' defense forces are overwhelmed by the sheer power and size of the enemy. The player controls the mysterious "Freedom Fighter", a pilot with no official connection to any government, who flies off to stop the N.A.C.

Reception
The Master System version received positive reviews upon release. Computer and Video Games scored it 82% in 1990. Mean Machines Sega and S: The Sega Magazine also gave the Master System version 82% scores.

The four reviewers of Electronic Gaming Monthly gave the Game Gear version ratings of 4, 5, 5 and 5 out of 10. They described the gameplay as repetitive, uninteresting, and lacking in both intensity and challenge, though they said the graphics are decent.

Melvin Mooney. Melvin Mooney (1893–1968) was an American physicist and rheologist.

Life

Mooney was born in Kansas City, Missouri. He achieved an A.B. degree from the University of Missouri in 1917 and a PhD in physics from the University of Chicago in 1923. He worked for the United States Rubber Company.

He developed the Mooney viscometer (used to measure viscosity of rubber compounds during curing) and other testing equipment used in the rubber industry. He also proposed the Mooney-Rivlin solid constitutive law describing the hyperelastic stress–strain behavior of rubber. He was the first recipient of the Bingham Medal from the Society of Rheology in 1948. He received the Charles Goodyear Medal in 1962. He is the namesake of the Melvin Mooney Distinguished Technology Award of the American Chemical Society Rubber Division.

SAIFI. The System Average Interruption Frequency Index (SAIFI) is commonly used as a reliability index by electric power utilities. This index measures the average number of times that a system customer experiences an outage during the year or during a given time period.

SAIFI is normally calculated on either yearly or monthly basis. SAIFI is calculated as:

where  is the failure rate and  is the number of customers for location . In other words,

Many factors cause power interruptions, including weather, vegetation patterns, and utility practices. Utilities can report interruption duration values with major events (such as snowstorms or hurricanes), without major events, or both.

SAIFI is measured in units of interruptions per customer. 

According to IEEE Standard 1366-1998 the median value for North American utilities is approximately 1.10 interruptions per customer.

Strip (Unix). In Unix, Plan 9, and Unix-like operating systems, the strip program is a command-line utility used to remove non-essential information from executable binary programs and object files. This information, which is not required for execution, typically includes debugging data, symbol tables, relocation information, and other metadata. Its primary purpose is to reduce the file size of the binary executable and potentially increase performance. The output of this process is known as a stripped binary.

Description
strip is a GNU binary utility that is used to remove information in a compiled binary or object file that is not needed for its execution. This information typically includes debugging information and symbol tables; however, the exact scope of the changes made to the binary is left to the discretion of the program's implementer by using the command-line options.

Using strip can enhance the security of a binary by making it more difficult to reverse-engineer. The absence of symbol and debugging information complicates the program analysis of the binary.

The effect of strip can also be achieved directly by using the compiler or linker to perform the same process. A compiler is a program that translates source code written in a high-level programming language (like C or C++) into machine code that the computer’s processor can execute. A linker, on the other hand, takes one or more object files generated by the compiler and combines them into a single executable file, resolving any symbol references between them.

For example, in the GNU Compiler Collection (GCC), this is done by using the "-s” option with gcc. This tells the linker to remove debugging information and symbols during the linking process, resulting in a smaller, stripped executable.

The GNU Project ships an implementation of strip as part of the GNU Binutils package. strip has been ported to other operating systems including Microsoft Windows.

Tripwire (company). Tripwire, Inc. is a software company based in Portland, Oregon, that focuses on security and compliance automation. It is a subsidiary of technology company Fortra.

History
Tripwire's intrusion detection software was created in the 1990s by Purdue University graduate student Gene Kim and his professor Gene Spafford. In 1997, Gene Kim co-founded Tripwire, Inc. with rights to the Tripwire name and technology, and produced a commercial version, Tripwire for Servers. 

In 2000, Tripwire released Open Source Tripwire.

In 2005, the firm released Tripwire Enterprise, a product for configuration control by detecting, assessing, reporting and remediating file and configuration changes. In January 2010, it announced the release of Tripwire Log Center, a log and security information and event management (SIEM) software that stores, correlates and reports log and security event data. The two products can be integrated to enable correlation of change and event data. August 21, 2009, the firm acquired Activeworx technologies from CrossTec Corporation.

Revenues grew to $74 million in 2009.  In October 2009, the company had 261 employees; that number grew to 336 by June 2010.

By May–June 2010, the company had over 5,500 customers and had announced that it had filed a registration statement with the Securities and Exchange Commission for a proposed initial public offering of its common stock. A year later, the company announced its sale to the private equity firm Thoma Bravo, ending its $86 million IPO plans.  CEO Jim Johnson cited the firm's failure to reach the $100 million revenue milestone in 2010 as well as changing IPO market expectations as reasons for not going through with the IPO. The day following the acquisition, the company laid off about 50 of its 350 employees.

Tripwire acquired nCircle, which focused on asset discovery and vulnerability management, in 2013.

In December 2014, Belden announced plans to buy Tripwire for $710 million. The acquisition was completed on January 2, 2015. In February 2022, Belden announced to sell Tripwire to HelpSystems (HelpSystems was renamed Fortra later that year).

Brisbane Linked Intersection Signal System. Brisbane Linked Intersection Signal System or BLISS was Brisbane City Council's ITS infrastructure platform.  This system incorporates large scale Traffic Signal control, a Real Time Passenger Information System (RAPID), and other infrastructure for managing and monitoring the road network for the Greater Brisbane Area.

For many years Brisbane City Council was very progressive amongst local governments in development and implementation of intelligent transport systems (ITS) solutions, and BLISS is one of the results of these endeavours.

History
The BLISS project began in the mid-1980s to replace separate legacy systems for traffic signal coordination within the city, and pioneered the use of local co-ordination modules integrated with, or connected to the traffic signal controller in the field.

BLISS was previously used in Brisbane to control approximately 900 sets of traffic signals throughout the city. It was replaced by SCATS.

BLISS was also used for a number of years along Jalan Tebrau in Johor Bahru, Malaysia. It is no longer used, developed or supported.

Active data structure. An active data structure is a data structure with an associated thread or process that performs internal operations. More specifically, an active data structure is associated with a computing resource, which contains one or more concurrently executing processes, and data associated with those processes. Communication is modeled using remote procedure calls, as opposed to shared memory or message passing. The active data structure's internals are hidden behind its RPC interface, and may be accessed concurrently. Common examples include databases and file systems. Active data structures can perform maintenance when resources would otherwise be idle, and present multiple views of the data.

Example 

A queue provided by the hardware or operating system is generally not unbounded, but rather has finite capacity. Suppose that the application has a strong requirement to never lose queue items. Then, the writing process must be modified to save items to a high-capacity storage medium if the queue is full, and the reading process must read the items back. Using the concept of active data structures, one can instead consider an "active queue" which manages saving and retrieving items from the high-capacity storage. Although there are now three running processes instead of two, potentially making synchronization more complex, the high level reader-writer abstraction for using an active queue is still simple and clear.

Formalization 

Self-adjusting computation is a technique for creating incremental computing programs that maintain internal state and can adjust to new inputs more efficiently than recomputing from scratch. This suggests that active data structures can be formalized by introducing the notion of time to the typical algebraic characterization of data structures. Specifically, Kanat Tangwongsan proposes that an active data structure is an algebra with these three meta-operations:

 perform("operationi(·)", t) will perform the operation operationi at the time t. If operationi(·) returns a value ri, then the meta-operation returns the value ri.
 The meta-operation undo(t) causes an undo of the operation at the time t. This is used for modeling incremental computation.
 The meta-operation update(t) informs the data structure to "synchronize" up to time t. This incorporates information about other processes.

Yager. Yager is a combat flight simulation video game developed by Yager Development and published by THQ, Kemco, and DreamCatcher Interactive. It was first released as an Xbox exclusive before later being ported to Microsoft Windows, both in 2003. The Xbox version was released in North America in later 2004, while the PC version was released in North America as Aerial Strike: Low Altitude - High Stakes: The Yager Missions in February 2005. In this game, gamers take on the role of Magnus Tide, a freelance pilot adventurer. Yager and Aerial Strike is set over 20 levels in which the player takes possession of various weapons and ships in an effort to accomplish each mission. The game, while well-received critically, was not a commercial success, largely in part due to a delayed North American release amidst a lack of advertising.

Gameplay
Yager is set in a futuristic world where countries' borders no longer exist and the earth is controlled by a number of megacorporations, most notably DST, as well as Proteus and Lobos Robotics. Although the old countries officially do not exist there are tell tale signs identifying each environment.

The Proteus Islands are a tropical paradise and the headquarters of the Proteus Corporation. The Free Trade Zone, a landscape dotted with turbines and palm trees, is the only zone not controlled by any corporation. The DST zone and surrounding fjords are connected to the Free Trade Zone by a system of caves, rivers, and deltas that run deep into DST territory. Bitterfeld is a desolate area littered with disused industrial buildings, crashed ships, abandoned machinery and other debris left behind by the old Progress Company.

Reception

Yager and Aerial Strike received "mixed or average reviews" according to the review aggregation website Metacritic.
