Ruby Autoflush

Google seems to need help with this particular association, so here goes.

In Ruby, to flush currently buffered data just once, call flush on the handle in question:

STDOUT.flush

To "autoflush", or continuously flush output immediately, set the sync attribute:

STDOUT.sync = true

References: flush, sync

Keyboard Shortcuts for Facebook Photo Tagging

Finally got around to tagging some photos in Facebook. I probably would not have bothered, had gleeBox not made it a bit tolerable by providing some form of keyboard shortcuts for the process:

• Created an "ESP vision" for the Page URL

  facebook.com/photo.php

  with the jQuery selector
  

  #photoactions>a[onclick],input[type="submit"]
#photoactions>a:first-child,input[type="submit"]



• Changed my "Shortcut to launch gleeBox" to ";"

This allows tagging to go as follows:

• Navigate to a Facebook photo album


• Press ;<ENTER> with left hand to enter tagging mode


• Tag at will


• Press ;<ENTER> again to leave tagging mode


• Left-click photo to move to the next photo

With the target crosshairs, it's about as close to an FPS you can get.

Mac Remote Desktop Connection Keyboard Shortcuts

To send the three-finger salute, Ctrl+Alt+Del, to a Windows box when you are connected using a Mac via Microsoft's Remote Desktop Connection, try Ctrl+Option+Delete (backspace).

Edit "Save Password" Exceptions in Google Chrome for Mac OS X

If you're a Google Chrome for Mac OS X user and you've ever hit "Never for this site" by accident (or have girlfriend who does so consistently), it's a little tricky finding out how to edit these "Save Password" exceptions. It's pretty clear for Windows' Chrome:

but I had trouble finding a solution for the Mac. A little snooping reveals that Chrome keeps its login information in a SQLite database file:

~/Library/Application Support/Google/Chrome/Default/Login Data

To remove an entry from the exception list, do the following:

1. Shut down Chrome


2. Probably a good idea to make a backup of the database file


3. Open the database file in a SQLite database browser; I use SQLite Database Browser


4. Select the "Browse Data" tab


5. Sites for which "Never for this Site" has been selected will have the value 1 for the column blacklisted_by_user. Double-click the desired cell, change the value to 0, and click "Apply Changes"


6. Save and close the database file


7. Restart Chrome
