In August 2007 Virgil Griffith, a Caltech computation and neural-systems graduate student, created a searchable database that linked changes made by anonymous Wikipedia editors to companies and organizations from which the changes were made. The database cross-referenced logs of Wikipedia edits with publicly available records pertaining to the internet IP addresses edits were made from. Griffith was motivated by the edits from the United States Congress, and wanted to see if others were similarly promoting themselves. The tool was designed to detect conflict of interest edits. Among his findings were that FBI computers were used to edit the FBI article in Wikipedia. Although the edits correlated with known FBI IP addresses, there was no proof that the changes actually came from a member or employee of the FBI, only that someone who had access to their network had edited the FBI article in Wikipedia. Wikipedia spokespersons received Griffith's "WikiScanner" positively, noting that it helped prevent conflicts of interest from influencing articles as well as increasing transparency and mitigating attempts to remove or distort relevant facts.
What was Griffith's tool designed to detect?
conflict of interest edits

The events of the Franco-Prussian War had great influence on military thinking over the next forty years. Lessons drawn from the war included the need for a general staff system, the scale and duration of future wars and the tactical use of artillery and cavalry. The bold use of artillery by the Prussians, to silence French guns at long range and then to directly support infantry attacks at close range, proved to be superior to the defensive doctrine employed by French gunners. The Prussian tactics were adopted by European armies by 1914, exemplified in the French 75, an artillery piece optimised to provide direct fire support to advancing infantry. Most European armies ignored the evidence of the Russo-Japanese War of 190405 which suggested that infantry armed with new smokeless-powder rifles could engage gun crews effectively. This forced gunners to fire at longer range using indirect fire, usually from a position of cover.
What was the French 75 optimised to directly support?
advancing infantry
