Methods And Blocks

Now, there may be addictive personalities, but thats not a disease. One can beat this "disease" by choosing not to drink. What other "diseases" can one beat by sheer willpower alone? source

The textbook way to do this would be to move all the business logic to libraries or controllers which are called by a 1 line method in the GUI. That way you can unit test the controller or library without dealing with the GUI. source

Suppose that a group wants to encrypt some information, then share the encryption key among the group members in a way that requires the consensus of the group to decrypt the information. I'm interested in a variety of scenarios where the breadth of consensus ranges from unanimity to an absolute majority. A useful technique can apply to symmetric keys, private keys, or both. I could take a crack at rolling my own method, as I'm sure many SO members could. But for the purposes of this question, I am interested only in methods that have been widely published and have withstood scrutiny by expert cryptanalysts. Journal citations are good, but interpretation of academic sources are very useful too. source

The technical reason is it's much more straightforward. When trying to erase data, the last thing you want to do is make a mistake, which is far more likely with a series of commands than running a single program. You might target the wrong drive, or get distracted halfway through, or not perform the steps in the best order. With DBAN, you know for sure that all the drives connected to the machine will be securely erased. source

Empty catch blocks are an indication of a programmer not knowing what to do with an exception. They are suppressing the exception from possibly bubbling up and being handled correctly by another try block. Always try and do something with the exception you are catching. source
