/prog/ - Bad Programming Practices

Name: Anonymous 2010-10-19 0:35

Each post must contain one bad programming practice to add to the list. I'll start:

In C++, overload library functions by using #define. That way it looks like you are using a familiar library function where in actuality you are using something totally different.

Never write comments - good code (that is *my* code) explains itself

good programmers should be able to trace through a program no problem and discover what it's doing without comments, now if you're learning the language then the examples should have them, but unless you're a retad you probably don't need comments k

Doing that increases the velocidensity of the sector of your hard drive where the file is stored, which in turn means that there will be less velocidensity available for your music files. If you use lossy compression you won't notice the difference, but your FLAC files will gradually lose information.

Would you say that the + operator is a bad practice in base₁ as well then?

>>16
Please learn about monoids, thank you.
(+) is a natural candidate for the monoidal operation because it is always associative _{_{and usually commutative}}.

You're just an idiot who read the definition of a monoid and thinks his babbling is relevant to the problem of str1 + str2. You make me so angry.

Perl 5 is pigu disugasutingu.

Using it is a programming error.

Why is
sub proc{my @arr=('a','b','c');return @arr};print( (proc())[1] );,
possible, but not
sub proc{my %h=('a'=>'b','c'=>'d');return %h};print( (proc()){'a'} );

Because perl only has scalar and list contexts.
Use return \%h; and proc()->{a}, no True Programmer uses anything but references.

Also, it works exactly as you have it in Perl 6. Try it: http://try.rakudo.org/

>>37

Refs are a pain in perl5. It's the only time sigil variance causes problems (indirectly) for me. OTOH in Perl 6 refs are implicit most of the time, and during assignment you use the binding operator instead of taking a ref and assigning that.
