"Lurking thresholds" are fun: I used pre-Racket to read files of numerical data, created by different agencies across the country. The code looked for something that looked like a date (out of about 10 formats), and moved on from there to read a few hundred lines of gradually changing groups of numbers.
The code was quite good at rummaging beyond various useless headers that were created over the years by new programmers attempting to improve the world... until one day, when someone actually made a truly useful header with an example that contained representative data. rac On Mar 24, 2016, at 2:14 PM, Hendrik Boom wrote: > On Thu, Mar 24, 2016 at 08:59:50PM +0100, Jos Koot wrote: >> Hi >> >> In all computer languages it is more difficult to read data than to write >> them, I think. > > Perhaps because when you write data you know what you are writing and > are in control.
