Data Detective – All Day Long
Today has been long... Very long... I've done precious little other than track down data issues for the back-end system I've built. It's not exciting because it's data errors, and not logic errors, and to make things even worse, it's not a crashing bug - it's a logic problem that leads to experimental results that look very wrong - because they likely are misrepresented and not mis-handled.
I know it's all part of the job, and today was as good as any for doing this - because I didn't have a lot to do otherwise, but it's hard, nasty work if you aren't set up for the necessary data links, and in today's case - I wasn't. So I did a lot of visual inspection and narrowing down of data sets, but in the end, I got the results I needed.
I think the logic we're using for extracting the referring source of the traffic is not right. But how to fix it without breaking the other mappings is something I'm going to leave to the original author.
