VX-REXX. VX-REXX is a highly extensible REXX GUI development system for OS/2 developed by Watcom and initially released in 1993.

Much of the new code in eComStation and ArcaOS has been written using VX-REXX.

Though REXX is itself a 3GL, the VX-REXX interface allows you to build REXX programs using a combination of 3GL and 4GL techniques; its drag-and-drop interface to inserting code allows quite complex programs to be built without actually entering any code.

VX-REXX's interface is itself written in VX-REXX, which means that it can be extended and/or modified using REXX code; it also has a number of macro hooks which can be used to add to its functionality directly.

The toolbox contains a number of standard tools (static text, group box, push button, radio button, check box, picture box, image push/radio button, list box, combo box (and drop-down), single and multiline entry field, slider) and some more specialized ones (container, value-set, notebook, DDE client, timer). Additional controls can be built using SOM and distributed as .DLL files; anything from simple variants of existing controls (such as a tri-state check box, or a self-validating entry field) to completely custom-drawn controls (for example, a self-contained tic-tac-toe board) can be written in C, compiled, and added to a VX-REXX project.

Intrepid Potash. Intrepid Potash, Inc. (), based in Denver, Colorado, is a fertilizer manufacturer. The company is the largest producer of potassium chloride, also known as muriate of potash, in the United States. It owns three mines, all in the Western U.S., near the cities of Carlsbad, New Mexico, Moab, Utah, and Wendover, Utah.

Mines

Carlsbad
There are three sites approximately  East of Carlsbad, New Mexico. The East facility produces sylvite and langbeinite potash, and is capable of fully processing its ore to the storage or shipment stage. The West facility (currently shut down) produced mainly traditional potash, which is shipped by truck to be processed at the North facility for final storage or shipping.

Moab

The Moab or Kane Creek potash mine () is located along the right (northwest) bank of the Colorado River, about 20 miles (30 km) west of Moab, Utah, at the south end of State Route 279 and the Union Pacific Railroad. The location is known as Potash on U.S. Geological Survey (USGS) topographic maps, and is east of Dead Horse Point State Park and Canyonlands National Park. According to USGS reports, the Paradox Basin contains up to 2.0 billion tons (1.8 billion metric tonnes) of potash, with the primary mine being the one at Kane Creek.

The plant was built by the Texas Gulf Sulphur Company in the early 1960s, opening in 1963 as a conventional underground mine. Later that year, an explosion trapped 25 miners, of whom only seven were able to survive, by building a barricade to trap fresh air. In 1970, operations were changed to a system that combines solution mining and solar evaporation. River water is pumped into the mine and dissolves the potash, after which the brine solution is pumped to evaporation ponds. Intrepid bought the mine in 2000 from the Potash Corporation of Saskatchewan, which had bought Texas Gulf in 1995.

Wendover

The Wendover potash mine is located about 120 miles west of Salt Lake City, Utah, and has been actively used for potash production since 1917. Potash production from natural occurring brines at the Wendover facility dates back to World War I. During the period from 1920 to 1936, a number of unsuccessful attempts were made to commercially produce potash. By 1939, a successful commercial potash operation was achieved and is still in production.

Lobbying
In 2015, a law firm associated with former U.S. Senator Norm Coleman started lobbying the U.S. State Department on behalf of Intrepid Potash to increase sanctions against Belarus. In 2021, the United States sanctioned Belarusian potash firms, raising potash prices worldwide.

CodeLite. CodeLite is a free and open-source IDE for the C, C++, PHP, and JavaScript (Node.js) programming languages.

History 

In August 2006, Eran Ifrah started an autocomplete project named CodeLite. The idea was to create a code completion library based on ctags, SQLite (hence, CodeLite), and a Yacc based parser that could be used by other IDEs. Later Clang became an optional parser for code completion, greatly improving its functionality.

LiteEditor, a demo application, was developed for demonstrating CodeLite's functionalities. Eventually, LiteEditor evolved into CodeLite.

General 

CodeLite is a free, open-source, cross-platform IDE for the C/C++ programming languages using the wxWidgets toolkit. To comply with CodeLite's open-source spirit, the program itself is compiled and debugged using only free tools (MinGW and GDB) for Mac OS X, Windows, Linux and FreeBSD, though CodeLite can execute any third-party compiler or tool that has a command-line interface. CodeLite also supports PHP and JavaScript development (including Node.js support).

CodeLite features project management (workspace/projects), code completion, code refactoring, source browsing, syntax highlighting, Subversion integration, cscope integration, UnitTest++ integration, an interactive debugger built over gdb and a source code editor (based on Scintilla).

CodeLite is distributed under the GNU General Public License v2 or Later. It is being developed and debugged using itself as the development platform with daily updates available through its Git repository.

List of countries by bismuth production. Bismuth  is a chemical element that has the symbol Bi and atomic number 83. This heavy, brittle, white crystalline trivalent other metal has a pink tinge and chemically resembles arsenic and antimony.

Of all the metals, it is the most naturally diamagnetic, and only mercury has a lower thermal conductivity. It was long considered to be the last naturally occurring non-radioactive element, although it is now known to be very slightly radioactive, with a half-life longer than the estimated heat death of the universe.

Bismuth compounds are used in cosmetics and in medical procedures. As the toxicity of lead has become more apparent in recent years, alloy uses for bismuth metal as a replacement for lead have become an increasing part of bismuth's commercial importance.

Hydraulic structure. A hydraulic structure is a structure submerged or partially submerged in any body of water, which disrupts the natural flow of water. They can be used to divert, disrupt or completely stop the flow. An example of a hydraulic structure would be a  dam, which slows the normal flow rate of the river in order to power turbines. A hydraulic structure can be built in rivers, a sea, or any body of water where there is a need for a change in the natural flow of water.

Hydraulic structures may also be used to measure the flow of water.  When used to measure the flow of water, hydraulic structures are defined as a class of specially shaped, static devices over or through which water is directed in such a way that under free-flow conditions at a specified location (point of measurement) a known level to flow relationship exists.  Hydraulic structures of this type can generally be divided into two categories:  flumes and weirs.

Western Hirondelle. 

Western Hirondelle (specifically the Western PGK-1 Hirondelle) is a Canadian two-seat aircraft for cross country and recreational flying, designed by Western Aircraft Supplies to be homebuilt from plans. The name is French for the Swallow, and the model designation includes the initials of the designers Jean Peters, Glenn Gibb, and John Kopala.

Description
The prototype first flew in 1976. The Hirondelle is built primarily of wood and cloth. It is a low-wing cantilever monoplane with a fixed tail-wheel landing gear and seats two side-by-side. It was designed for the Lycoming O-235 but accommodates engines from .

The primary wing structure is a wood box spar connected to an aileron spar by ribs cut on a band saw. To the front of the main spar are strapped D-shaped fiberglass fuel tanks which can carry up to 12 imperial gallons per wing. Over the tanks is the framing and plywood skin of the wing's nose. Behind the main spar, the wings are covered in cloth. The wing section is the NACA 23012 with a  chord; the wing is rectangular, being straight and untapered. No flaps were fitted to the prototype, but they were being considered.

The fuselage is built up from spruce and covered in  plywood. Cabin width on the prototype was . The main gear uses Wittman tapered rods and was designed to take standard Cessna wheel pants. As with the Wittman Tailwind, the mains connect to the engine mount. The wing tanks feed a  header tank through automotive electric fuel pumps. The header tank feeds the engine by gravity.

The prototype weight includes an upholstered interior, a full electrical system and venturi driven gyros. With its  engine it can cruise at  at 2500 rpm.

David August (computer scientist). David I. August (born November 27, 1970) is a professor of computer science at Princeton University specializing in compilers and computer architecture.  August is a strong advocate of alternatives to parallel programming to address the software impact of multi-core computing.

August was born in Troy, New York and raised in Parsippany-Troy Hills, New Jersey, graduated summa cum laude in electrical engineering from Rensselaer Polytechnic Institute in 1993, and received his PhD in electrical and computer engineering from the University of Illinois at Urbana-Champaign in 2000 under advisor 
Wen-mei Hwu.   His thesis, entitled Systematic Compilation for Predicated Execution, represented a breakthrough in compilers. 
Specifically, it showed how a compiler could generate efficient code for architectures with branch predication, such as Intel's IA-64.

In 1999, August was selected as one of five new Ph.D.'s to watch by the Chronicle of Higher Education.  Since then, he has produced dozens of articles relating to compilers and computer architecture.  The IEEE Computer Society's annual "Top Picks from Computer Architecture Conferences" has recognized his work on microprocessor fault tolerance and his work on multi-core computation for relevance and significance to the field.

In 2012, he testified as an expert witness in the Oracle America, Inc. v. Google, Inc. patent lawsuit on behalf of Google and stated that the Dalvik virtual machine used in Android did not infringe on Oracle's symbolic reference patent.

Awards and honors
August became an IEEE Fellow in 2015 "for contributions to compilers and architectures for multicore and parallel processing systems".

Himalayan Aviation. Himalayan Aviation () was an airline based in India that operated in the northern parts of the Indian subcontinent until its nationalisation and merger into Indian Airlines in 1953. On 20 February 1950, Himalayan Aviation ran the first ever international flight from Nepal, from Gauchar, Nepal, to Calcutta, India.

Himalayan Aviation began with chartered flights. Over time, it expanded to night-mail services and scheduled passenger flights. In order to maximize revenue, it began taking on passengers on its night-mail flights as well.

On 7 December 1951, Pakistan detained a Himalayan Aviation flight from Ahmedabad, India, to Kabul, Afghanistan, at the stopover point in Karachi. Pakistan had previously denied use of the direct Delhi-Kabul air-corridor that overflew the North West Frontier Province. India and Pakistan had worked out an alternative Ahmadabad-Karachi-Zahedan (Iran)-Kabul route.

Fleet 
The fleet mostly consisted of Douglas DC-3 aircraft.

Fluorine perchlorate. Fluorine perchlorate, also called perchloryl hypofluorite is the rarely encountered chemical compound of fluorine, chlorine, and oxygen with the chemical formula  or . It is an extremely unstable gas that explodes spontaneously and has a penetrating odor.

Synthesis 

One synthesis uses fluorine and perchloric acid, though the action of ClF5 on water is another method.

Another method of synthesis involves the thermal decomposition of tetrafluoroammonium perchlorate, , which yields very pure  that may be manipulated and frozen without explosions.

Structure 

Fluorine perchlorate is not analogous to perchloric acid because the fluorine atom is more electronegative than oxygen. It contains an oxygen atom in a rare oxidation state of 0 due to the electronegativity of oxygen, which is higher than that of chlorine but lower than that of fluorine.

Safety 

FClO4 has a very dangerous and unpredictable series of reactions associated with it, as a covalent perchlorate (chlorine in the +7 oxidation state) and a compound featuring a very sensitive O-F single bond. Small amounts of reducing agents, such as organic compounds, can trigger explosive detonation. Products of these decomposition reactions could include oxygen halides, interhalogen compounds, and other hazardous substances.

Accidental synthesis is possible if precursors are carelessly mixed. Like similar covalent fluorides and perchlorates, it needs to be handled with extreme caution.

Reaction 
FClO4 is a strong oxidant and it reacts with the iodide ion:

FClO4 can also react with tetrafluoroethylene:

It may be a radical addition reaction.
