问题 I have a computer that's running Windows 7, that I do most of my development on. I have a spare laptop running Ubuntu. They are both connected to the same wifi, and I'm developing in Rails. Is there a way that I can use my spare laptop (Ubuntu) as a local server for development and testing that I would be able to connect to through my other computer (Windows 7)? If it's not possible, how would I use my computer (Windows 7) as a local server for testing in Rails? I have XAMPP installed, I just

问题 I created a MySQL server. Now the user login has access to all databases. I want this user not to have access (so can't do anything) to 3 databases: information_schema mysql phpmyadmin So the user can use all databases except these 3. How can I get this done? 回答1: A brief version of how to do this (which is mostly explained in the link I posted above): You need to REVOKE that user's GLOBAL privileges - this is because MySQL's privilege system is top-down. If they have a GLOBAL privilege to

问题 On a given line of the RStudio console or script writing area, the cursor as it flashes on the screen is shifted from its true position, where text is inserted. Say I want to delete a character on a given line. I click right in front of it, and the red cursor flashes where it should. But when I press backspace, the character six spots to the left gets deleted instead. This behaviour gets worse as the line goes on, so near the end of a long line, the offset is of 13 characters while it is only
