I'm reminded of a close friend of mine... once he was asked to
review some code, after the sole author had spent a few weeks
on it. I was lucky (?) enough to be in the room to hear him
actually say: "That's... cute. Not *wise* but cute. Do you
remember what functions are?" I don't recall there being a
response.
I remember seeing some stupid production code that was used at a
company I worked at for a while. They were developing jsp pages
as part of their training until they got sections hired out
(sorta lowest bidder thing, where you would go to them rather
than export work over seas).
The code in question was to convert the input 16byte input from
a database into it's GUID id as a text string in java. I don't
remember it exactly, but it went something like...
[code]
//remember, java
String toGuid(byte input[16]) {
String ID = "{";
if (Integer.toHexString(input[5]).length < 2)
ID = ID + "0";
ID = ID + Integer.toHexString(input[5]);
if (Integer.toHexString(input[6]).length < 2)
ID = ID + "0";
ID = ID + Integer.toHexString(input[6]);
//repeat for other 14 bytes, plus adding dashes and ending brace
return ID;
}
[/code]
It didn't help the company's Java class that they taught didn't
go into low level operations like And and Or and bit shifting. I
ended up rewriting it, then they wanted it 'super documented'
because they couldn't understand what > were for. (I think there
was more documentation commenting low level explanations of what
it was doing than actual code).
