Strategies For Finding Fixes
- The bubble-up strategy simply records pairs of symptoms and fixes. The most frequent set of pairs is then presented as a tentative solution, which is then attempted. If the fix works, that fact is further recorded, along with the configuration of the presenting system, into a solutions database.
- Oddly enough, shutting down and booting up again manages to 'fix,' or at least 'mask,' a bug in many computer-based systems; thus reboot is the remedy for distressingly many symptoms in a 'fix database.' The reason a reboot often works is that it causes the RAM to be flushed. However, typically the same set of actions are likely to create the same result demonstrating a need to refine the "startup" applications (which launch into memory) or install the latest fix/patch of the offending application.
- Currently, most expertise in finding fixes lies in human domain experts, who simply sit at a replica of the computer-based system, and who then 'talk through' the problem with the client to duplicate the problem, and then relate the fix.

Famous quotes containing the words strategies, finding and/or fixes:
“By intervening in the Vietnamese struggle the United States was attempting to fit its global strategies into a world of hillocks and hamlets, to reduce its majestic concerns for the containment of communism and the security of the Free World to a dimension where governments rose and fell as a result of arguments between two colonels’ wives.”
—Frances Fitzgerald (b. 1940)
“The thing that’s between us is fascination, and the fascination resides in our being alike. Whether you’re a man or a woman, the fascination resides in finding out that we’re alike.”
—Marguerite Duras (b. 1914)
“Constancy in love is a perpetual inconstancy which fixes our hearts successively to all the qualities of the person loved—sometimes admiring one and sometimes another above all the rest—so that this constancy roves as far as it can, and is no better than inconstancy, confined within the compass of one person.”
—François, Duc De La Rochefoucauld (1613–1680)
