I'm essentially preparing phrases to be put into the database, they may be malformed so I want to store a short hash of them instead (I will be simply comparing if they exist or not, so hash is ideal). I assume MD5 is fairly slow on 100,000+ requests so I wanted to know what would be the best method to hash the phrases, maybe rolling ou...
Hi, I'm looking for a elegant way to assign the value stored inside an Hash into a pre-existed object. Just to be clear, if I have an object, say obj with two attributes, say name and age, I want to assign this values coming from an hash without do something like: obj.name = hash[:name] obj.age = hash[:age] Thanks for your attention...

This means headers will probably have been sent already and so using sessions may not work. I recommend they call session_start ...

Is this a common practice? Any suggestions on improving this? Also, should I use defined...
If I understand correctly, calling if (exists $ref->{A}->{B}->{$key}) { ... } will spring into existence $ref->{A} and $ref->{A}->{B} even if they did not exist prior to the if! This seems highly unwanted. So how should I check if a "deep" hash key exists? ...
