Garbage collection can be made real-time and verifiable

An efficient means of memory reclamation (also known as Garbage Collection) is essential for Machine Intelligence applications where dynamic storage allocation is desired or required. Solutions for real-time systems must introduce very small processing overhead and must also provide for the verification of the software in order to meet the application time budgets and to verify the correctness of the software. Garbage Collection (GC) techniques are proposed for symbolic processing systems which may simultaneously meet both real-time requirements and verification requirements. The proposed memory reclamation technique takes advantage of the strong points of both the earlier Mark and Sweep technique and the more recent Copy Collection approaches. At least one practical implementation of these new GC techniques has already been developed and tested on a very-high performance symbolic computing system. Complete GC processing of all generated garbage has been demonstrated to require as little as a few milliseconds to perform. This speed enables the effective operation of the GC function as either a background task or as an actual part of the application task itself

(SNP105) Charles Ross interviewed by Dorothy Noble Smith, transcribed by Alan S. Brenner

Records an interview with Charles Ross, whose father, Dr. Charles J. Ross, was one of several local physicians who served the families living in the mountains prior to the advent of Shenandoah National Park. Charles J. Ross was born in Taylor County, WV, in 1881. He received his medical degree from the Medical School of Virginia in 1905, and later studied surgery in New York City. Mr. Ross describes the primitive conditions under which his father worked, where access to many of his patients was often limited to horse trails and foot paths. Recalls several deadly outbreaks of diphtheria, tuberculosis and typhoid fever, which were common in the area, as well as the Great Influenza Epidemic of 1918-1919, which caused the deaths of millions of Americans across the country. Mr. Ross often rode along with his father during school vacations and gives his impression of the many mountain people he encountered, including many local moonshiners.https://commons.lib.jmu.edu/snp/1087/thumbnail.jp
