Code Snippet Of the Day (CodeSOD) features interesting and usually incorrect code snippets taken from actual production code in a commercial and/or open source software projects.
Eli sends us something that's not quite a code sample, despite coming from code. It's not a representative line, because it's many lines. But it certainly is representative.
Here's the end of one of their code files:
As often happens, Luka started some work but didn't get it across the finish line before a scheduled vacation. No problem: just hand it off to another experienced developer.
Luka went off for a nice holiday, the other developer hammered away at code, and when Luka came back, there was this lovely method already merged to production, sitting and waiting:
"We use a three tier architecture," said the tech lead on Cristian's new team. "It helps us keep concerns separated."
This statement, as it turned out, was half true. They did divide the application into three tiers- a "database layer", a "business layer", and a "presentation layer". The "database layer" was a bunch of Java classes. The "business layer" was a collection of Servlets. And the "presentation layer" was a pile of JSP files.
Alexandra inherited a codebase that, if we're being kind, could be called "verbose". Individual functions routinely cross into multiple thousands of lines, with the longest single function hitting 4,000 lines of code.
Very little of this is because the problems being solved are complicated, and much more of it is because people don't understand how anything works.
