The Skewb (/ ˈ s k juː b /) is a combination puzzle and a mechanical puzzle similar to the Rubik's Cube. It was invented by Tony Durham and marketed by Uwe Mèffert . [ 1 ] Although it is cubical, it differs from the typical cubes ' construction; its axes of rotation pass through the corners of the cube, rather than the centers of the faces.
The Skewb Diamond, slightly twisted. The Skewb Diamond is an octahedron -shaped combination puzzle similar to the Rubik's Cube. It has 14 movable pieces which can be rearranged in a total of 138,240 possible combinations. This puzzle is the dual polyhedron of the Skewb. It was invented by Uwe Mèffert, a German puzzle inventor and designer.
Mingw-w64 is a free and open-source suite of developments tools that generate Portable Executable (PE) binaries for Microsoft Windows. It was forked in 2005–2010 from MinGW (Minimalist GNU for Windows). Mingw-w64 includes a port of the GNU Compiler Collection (GCC), GNU Binutils for Windows (assembler, linker, archive manager), a set of ...
A program solving a large mathematical or engineering problem will typically consist of several parallelizable parts and several non-parallelizable (serial) parts. If the non-parallelizable part of a program accounts for 10% of the runtime (p = 0.9), we can get no more than a 10 times speedup, regardless of how many processors are added. This ...
Interprocedural optimization. Interprocedural optimization (IPO) is a collection of compiler techniques used in computer programming to improve performance in programs containing many frequently used functions of small or medium length. IPO differs from other compiler optimizations by analyzing the entire program as opposed to a single function ...

Compilers implementing this technique realize that (a + b) will not change, and so only calculate its value once. [9] Constant folding and propagation [10] replacing expressions consisting of constants (e.g., 3 + 5) with their final value (8) at compile time, rather than doing the calculation in run-time. Used in most modern languages.
