| stoft | "Understood; though independent checks and tests are still the best method to find hidden anomalies and overlooked issues. When you fix the glitch, ..." | Read more » | almost 9 years ago | |||

| stoft | "The CSV data files have poorly formatted data. The text of the files often looks like this: 206.809,2.55,2.5500000000000003,7.6499999999999995,2.55..." | Read more » | almost 9 years ago | |||
