• Drupal blocks are syncing?

  - by Kevin

  I am trying to enable a new theme on a site running Drupal 6.16. I enable it fine, it has its own namespace in the theme and theme registry. However when you go to the Blocks section, changing a block here will affect that blocks placement in all the other themes, and vice versa. Is this normal behavior? Where should I begin looking to solve this issue?

• Shift Operators in C++

  - by Codeguru

  If the value after the shift operator is greater than the number of bits in the left-hand operand, the result is undefined. If the left-hand operand is unsigned, the right shift is a logical shift so the upper bits will be filled with zeros. If the left-hand operand is signed, the right shift may or may not be a logical shift (that is, the behavior is undefined). Can somebody explain me what the above lines mean??

• vim - open file with complete path

  - by David Oneill

  If I have a file that contains a complete path for a file, is there a way to highlight the filename (using visual mode) and open the file?

Otherwise, use the current folder (IE default behavior) Is this possible?
