Armware

My left arm hardware (sans the ‘lag’ screws that could not be safely removed). I wonder what this much surgical grade titanium is worth…

Aeronautics

I’ve come to realize, that I greatly enjoy the act of learning and gaining knowledge. So, I’ve enrolled in a couple of graduate classes in Aeronautics, just because I find it to be a fascinating subject.

• Command-Shift-3: Take a screenshot of the screen, and save it as a file on the desktop
• Command-Shift-4, then select an area: Take a screenshot of an area and save it as a file on the desktop
• Command-Shift-4, then space, then click a window: Take a screenshot of a window and save it as a file on the desktop
• Command-Control-Shift-3: Take a screenshot of the screen, and save it to the clipboard
• Command-Control-Shift-4, then select an area: Take a screenshot of an area and save it to the clipboard
• Command-Control-Shift-4, then space, then click a window: Take a screenshot of a window and save it to the clipboard
• The following keys can be held down while selecting an area (via Command-Shift-4 or Command-Control-Shift-4):
  • Space, to lock the size of the selected region and instead move it when the mouse moves
  • Shift, to resize only one edge of the selected region
  • Option, to resize the selected region with its center as the anchor point

Formats

Different versions of Mac OS X have different formats for screenshots.

The default screenshot format can be changed, by opening Terminal (located at /Applications/Utilities/Terminal) and typing in:

defaults write com.apple.screencapture type image_format killall SystemUIServer

Where image_format is one of jpg, tiff, pdf, png, bmp or pict (among others). If you omit the second line, you will need to log out and in again for the change to take effect.

Grab and Preview Instead of using the keyboard shortcuts above, screenshots can be taken by using the Grab application included with Mac OS X. It is located at /Applications/Utilities/Grab. Some versions of the Preview application have an option under the File menu to take a screenshot.

From the Terminal The screencapture command in the Terminal can also be used to capture screenshots, and is useful for scripts. Here is an example.

screencapture -iW ~/Desktop/screen.jpg

I blinked a little, then tried a copy paste from the log file to put into a bug note and got this little gem from textpad:

Cannot cut, copy, or drag and dtop text containing null (code = 0) characters.

Sweet!

I opened the file up in a Hex Editor, and low and behold there were extra nulls chars all through it. Even though the xml header specified UTF-8, it looked like it was actually encoded in UTF-16.

A quick hack to my code to override encoding to use UTF-16, and the xml was now readable…. looks like SystemA swapped encoding without informing anyone or updating their code to output the correct incoding in the file encoding attribute… makes me wonder if they String all their XML together by hand with String concatenations instead of using an XML library (shudder). Just goes to show, just ’cause the encoding attribute says one thing, it might actually be something else. Never presume that inside the black box that is someone else’s application, good coding practices are followed.
