Boeing Calc. Boeing Calc was a spreadsheet package written by Boeing Computer Services, an independent subsidiary of aviation manufacturer Boeing. It had originally been developed as an in-house accounting tool, but was launched as a commercial product in April 1985 for IBM 4300 mainframes running IBM MVS and IBM PC microcomputers running DOS. The original launch price was $399 per copy for the PC version and $8,899 for a combined PC/mainframe bundle.

Boeing Calc could read and later write standard Lotus 1-2-3 files. It supported a maximum spreadsheet size of 16,000 columns by 16,000 rows, and was notable for introducing the concept of 3D spreadsheets. Each spreadsheet could have up to 16,000 pages, with cells prefixed by the page number; the upper-left cell of the third page was referred to as 3A1, for example. This concept was a precursor of the tabbed sheets included in Quattro Pro and later spreadsheets.

Version 3.0 was launched in August 1987 and introduced multi-user support on PC-based local area networks, with a price of $795 for a LAN licence. Version 4.0 followed in November of that year, with the price for a single-user licence reduced to $395. Unlike competitors such as Lotus 1-2-3 and Quattro it did not support graphics, although Boeing sold a companion program - Boeing Graph - that could produce 3D charts. Contemporary reviews of version 3.0 praised Boeing Calc's flexibility and ability to work with files of up to 32mb in size, but criticised its steep system requirements, slow speed, and reliance on disk-based virtual memory. Running on a high-end 6 MHz IBM PC AT with an Intel 8087 maths coprocessor, Infoworld's standard spreadsheet took 42.9 seconds to recalculate, versus 7.9 for the same sheet running in Lotus 1-2-3.

Towards the end of 1987 Boeing announced its intention to leave the microcomputer software industry. Boeing Computer Services was sold off as an independent entity, Garrison Software Corp, to West German software distributors m+s Elektronik. However the deal fell through and BCS reverted to Boeing's control, where it was eventually merged with Boeing Information Services. Boeing Calc ceased development in 1988, with the final copies being sold off to employees at a discount price of $50.

International Conference on Advances in ICT for Emerging Regions. International Conference on Advances in ICT for Emerging Regions (ICTer) is the successor to the seminal International Information Technology Conference (IITC) held in Sri Lanka since 1998. It provides a platform where research done in ICT is presented by both local and foreign Computer Scientists and IT Professionals. In order to get wider international participation and to promote computing research in the fast-emerging regions of the world especially in Asia-Pacific, it was decided to broadbase the IITC conference and link it with the related International Journal ICTer (www.icter.org).

Overview
The conference is attended by about 200 researchers and students each year. Topics of interest have included Technology, Applications, Human-Computer Interaction, Development Processes, and Social, Legal and Ethical Issues. The conference usually includes pre-conference and/or post-conference high-quality tutorials/workshops in areas of current interest in Information and Communication Technology.

The conference was initiated to mark the year of IT declared by the Government of Sri Lanka in 1998. Initially, it was organised by the Infotel Lanka Society and managed by the Council for Information Technology (CINTEC). Management was taken over by the University of Colombo School of Computing (UCSC) in 2003. Infotel Lanka Society organised by conference until 2006. Currently, the UCSC organise and manage the conference.

Mirror (programming). In computer programming, a mirror is a reflection mechanism that is completely decoupled from the object whose structure is being introspected. This is as opposed to traditional reflection, for example in Java, where one introspects an object using methods from the object itself (e.g. getClass()).

Mirrors adhere to the qualities of encapsulation, stratification and ontological correspondence.

Benefits 
Decoupling the reflection mechanism from the objects themselves allows for a few benefits:
 The object's interface is not polluted, so there is no danger of breaking reflection by overriding a reflective method.
 There can be different mirror systems.
 The mirror system can be removed entirely (potentially allowing for optimizations).
 A mirror system can operate on remote code, since it is not coupled with a particular machine.

Languages that use mirrors 
 Dart, via its reflect function.
 Inko, via its std::mirror module.
 Rubinius (Ruby implementation), via its Rubinius::Mirror.reflect method.
 Scala
 Swift, via its reflect function.

Gleaner-class gunboat. The Gleaner (or Pelter)-class gunboat was a class of six gunboats built for the Royal Navy in 1854 for use in the Crimean War.

Design
The Gleaner class was designed by W.H. Walker (who also designed the subsequent  and es). The ships were wooden-hulled, with steam power as well as sails, but of shallow draught for coastal bombardment in the shallow waters of the Baltic and Black Sea during the Crimean War.

Propulsion
Two-cylinder horizontal single-expansion steam engines built by John Penn and Sons, with two boilers, provided 60 nominal horsepower through a single screw, sufficient for .

Armament
Ships of the class were armed with one 68-pounder smooth bore muzzle loading cannon (SBML), one 32-pounder SBML (originally two 68-pounder SBMLs were planned but the forward gun was substituted by a 32-pounder) and two 24-pounder howitzers.

Grigore Brișcu. Grigore Brișcu (1884 in Bârlad – 1965 in Bucharest) was a Romanian engineer and inventor.

Biography 
At age 19, he enrolled in the National School of Bridges and Roads in Bucharest. While pursuing his engineering degree, he took some technical courses in  Paris and also earned a law degree from the University of Iași.

Inventor of the helicopter 
In 1909, Brișcu was the first engineer to begin experimenting with the cyclic variation of rotor blade pitch to ensure horizontal flight and stability in helicopters. He invented a prototype "air-carriage" with all the features of a helicopter-like flying-machine: horizontal, vertical and lateral movement and fixed-point landing. It was equipped with two coaxial propellers rotating in opposite directions. This was flown experimentally by the French aviator Paul Cornu, who built a prototype with an Antoinett engine. The Brișcu rotary engine was patented by the Romanian Office for Inventions (patent no. 2323/2046 of 1912).

Loebe Julie. Loebe Julie (December 10, 1920 - June 7, 2015) was an American engineer who has been credited with inventing the first operational amplifier circuit with differential inputs (1943), a topology which allowed much greater versatility in applications circuits and remains in wide use today.

Career
After earning a BSEE from the City College of New York in 1941, Julie worked at the Army Signal Corps in Fort Monmouth, NJ, as a civilian engineer for two years.   In 1943, NDRC Division 7 contracted Columbia University's Division of War Research to improve and simplify the multi-stage vacuum tube-based amplifier circuits designed by Karl D. Swartzel Jr. for use in the Western Electric M9 gun director.

Encouraged by George A. Philbrick, who was part of the Division 7 team, Julie designed a circuit using two dual-triode vacuum tubes that not only had the novel feature of a differential input, but used fewer tubes, was much faster (100 kHz gain-bandwidth product) and more power efficient (2 × 300 V at 10 mA, plus tube heater) than the previous circuits.

After the war, Julie returned to university, earning an MS in mathematics from New York University in 1954.  In 1956, he founded the company Julie Research Laboratories to produce precision resistors, calibration standards and related products.  The company was acquired by Ohm-Labs in 2001.

Sally Shlaer. Sally hashim Shlaer (December 3, 1938 – November 12, 1998) was an American mathematician, software engineer and software methodologist, known as co-developer of the 1980s Shlaer–Mellor method for software development.

Biography 
Born in Cleveland, Ohio, Shlaer received a BS in Mathematics in 1960 from Stanford University and started a graduate study at the Australian National University.

At Stanford Shlaer had started programming in Fortran and assembler. In 1965 she started as a software engineer at Los Alamos National Laboratory. In 1977 she became project manager in software development at Lawrence Berkeley Laboratory, where she guided the development of a new Integrated Control System for the Bay Area Rapid Transit system.

At Lawrence Berkeley, Laboratory Shlaer met Stephen J. Mellor, with whom she developed the Shlaer–Mellor method for software development. In 1985 together they founded the software development firm Project Technology Inc. Shlaer was also a Fellows of the Association for Computing Machinery.

Work

Software engineering 
Shlaer started her software engineering career at Los Alamos National Laboratory as a programmer. She designed and implemented an operating system to operate an electron accelerator to work in real time, and this project became her masterpiece.

At Lawrence Berkeley Laboratory, she led a team of software developers to build a new control system for the subway of the Bay Area Rapid Transit system. The existing control system software was considered impossible to continue using, making replacement necessary. Working with Steve Mellor, they replaced the original Fortran and assembly language code with new code, going from seventy thousand lines to two thousand. This analysis has since been called "legendary".

Shlaer–Mellor method 
 
In the developing of a new control system for the Bay Area Rapid Transit, Shlaer and Mellor sought to regulate mechanisms of software development and began to design new methods of project management. This resulted in the development of the Shlaer–Mellor method, which in the new millennium has evolved into Executable UML.

Petter Sørlle. Petter Sørlle (February 16, 1884 – May 29, 1933) was a Norwegian whaling captain and inventor.

Biography
Petter Martin Mattias Koch Sørlle was born at Tune (now Sarpsborg) in Østfold, Norway. Both his father and grandfather had been sailors. He was engaged in whaling from Vestfold and later participated in Antarctica whaling near the South Georgia Island and South Orkney Islands.

He invented slipways for whaling ships, which he patented in 1922. His invention was a device by which the whale could be fully drawn to the ship. The pickup slip was first used in the Antarctic Ocean by the whaling company Globus of Larvik on board the FLK Lancing during the season 1925–26.

Sørlle was the first manager of the United Whalers whaling shore station at Stromness, South Georgia. He carried out surveys and is commemorated by several place names in Antarctic waters.

Sørlle Buttress, the Sørlle Rocks and Cape Sørlle are all Antarctic features named after him.

List of features named by Sørlle 
During his running surveys, Sørlle named a number of features in the South Orkney Islands, including:
 Gerd Island
 Signy Island
 Reid Island
