I am too stupid to understand the article
I know this is bad practice but we had a program which mined a load of data from a database, reformatted and then stored it in a way useful for analysis. It was in Java and there was a lot of code of the form
stringBuffer.append(ident + ',' + a + ',' + b + ',' + c + '\n');
Now I know this is Bad Practice and a whole lot of other things but it worked, reliably and consistently. And it churned through millions of tuples in multiple tables in sensible time.
Then we acquired a new programmer who was asked to do something with this code. And we ended up with every occurrence changed to
[edit-the original single line version appears to have borked el reg formatting]
Because it was (a) more functional and (b) more correct and (c) more readable.
And...because if you asked it, Netbeans would carry out the conversion automatically.
Programming would be absolutely great if it wasn't for programmers.
