I had a very difficult to track down bug that ended up losing us a very big fish client, that came down to parsing a binary file with an ad-hoc parser that looked for the index of a header. They didn't realize that after the header was some metadata, so a small amount of metadata was interpreted as data. I fixed it by writing a proper ad-hoc parser that actually worked on a header-by-header level. But the damage was done and we had looked like buffoons to the client.

Was very hard for the team. There was a shouting match over it, some hard feelings. The code was written in the spirit GP alludes to by an enthusiastic executive who wanted to help lighten the load. I should've rejected the PR but was intimidated to reject the exec's code (not an engineering reason for an engineering decision!). The exec was a good data scientist but not as strong a coder as me, and parsing binary files is one of my specialties.

Friends don't let friends parse using "indexOf()".
