Very important in the introduction of a new programming language standard is that old programs (at least those who obey the outgoing standard) can be used once again, with the new standard. When we went from Fortran 66 to Fortran 77 the extended DO -loop was removed (the extended DO -loop means that if you do not change any of the DO -loop parameters you can jump out of the loop and then jump in again (this is somewhat contrary to the concept of structured programming). ... 2, June 1993, page 1. ...

It's a common misconception that black holes always have matter swirling into them. ... As this matter gets closer and closer to the black hole it piles up and a large, fairly flat disk forms.

... I am developing an Informed Prefetching and Caching system as part of the kernel in which it is very important that the memory assigned to hold the data does not get swapped to disk. Without any thought to swapping I used vmalloc() to assign memory to the data structures of the Informed prefetching system. ... I later realized that most probably the pages assigned using vmalloc() were getting swapped to the disk and when I referenced them, they were brought from the disk rather than memory. ...

Chapter 11. Specifying OpenGL Environment Variable Settings . ... Several antialiasing methods are available and you can select between them by setting the __GL_FSAA_MODE environment variable appropriately. ... To see the available values for __GL_FSAA_MODE along with their descriptions, run: nvidia-settings --query=fsaa --verbose . The __GL_FSAA_MODE environment variable uses the same integer values that are used to configure FSAA through nvidia-settings and the NV-CONTROL X extension. ...

... The choice of which type of electricity is called "positive" and which "negative" was made around 1750 by Ben Franklin, early American scientist and man of many talents (the stamp on the left commemorates his role as first US postmaster--and colonial postmaster before that). ... Franklin knew of two types of electric charge, depending on the material one rubbed. ... Later, when electric batteries were discovered, scientists naturally assigned the direction of the flow of current to be from (+) to (-...

... Extended-source photometry cannot be done in the same was as is done by omdetect , because information about the sources that omdetect used is not available to omsource . Basically, omdetect uses the pixels assigned to a source to compute source counts from the source, and the value obtained obviously depends on the ``thresh-hold level'' (please see the omdetect documentation for more information). Omsource uses each pixel within the aperture to obtain the source counts. ...

... They were determined as a result of orbit improving on the base of all kinds of optical observations available in the catalog of observations of the Minor Planet Center on March 16, 2014 (radar observations have not been used at this stage). ...
