In an effort to save toner/ink, some browsers shut off the ability to print the background images and colors.

In Firefox, if you go to File->”Page setup”, you can go to the “Format & Options” tab and click the “Print Background (Colors and Images)” box.

In Internet Explorer, you need to go to Tools->”Internet Options” which will bring up a dialog box.  Select the Advanced tab and scroll down in the Settings window until you find the heading “Printing” and select the checkbox next to “Print background colors and Images”.

Remember to undo this if you want to conserve ink/toner.

For the longest time, I thought the “Print Screen” or “PrtScr” Key on my keyboard was a throw back to much older computers with sheet fed dot matrix printers and would just print out the current Dos command shell.

Once I figured out how to use it in windows, it has become an invaluable tool.

I used to create presentations of source code issues. It was a great help to be able to grab a copy of the screen and place it in a Powerpoint slide or Word Doc.

If you need a complete screen capture or even just the current window, here is what you can do.

If you need to capture the complete screen, press the “Print Screen” button located near the top of the keyboard with the scroll lock or Pause key.   It may seem like nothing has happened, but the complete image of your current desktop has been saved into the clipboard in windows.

If you want to just capture the current window, make sure the window you want is active and press the  Alt and “Print Screen” keys together.

Now open Paint, MS Word or any other program capable of handling images, and type Ctrl-V.  This will take the image that has been captured into memory and place it in the program.  Now you can manipulate the image to crop it or use it in your document.

This is a built in function of the MS Windows Operating system.

If you need more control there are other applications that can let you capture portions of the screen at any time and create a file with a simple keystroke, such as SnagIt!

Motorola DCT6412 (Comcast DVR) 30-second skip

I have a Tivo and missed the 30 second skip that was available and I found that the same was available with the Comcast Cable remote.

1) Press the button at the top of the remote to put it into Cable Box control mode.

2) Press and hold the button until the button blinks twice.

3) Type in the code 994. The button will blink twice.

4) Press (do not hold) the button

5) Type in the code 00173 (for 30 second Skip).

6) Press whatever button you want to map the skip, I used the help button as I have never used it myself.

Welcome to 30 second skipping.

I had to send a large file (about 100MB) to a client for analysis.  They did not have an anonymous ftp server so I had to figure a way to e-mail the file to them and then have a way to put it back together.

I found the split command very useful.  I use Linux when I can but have installed Cygwin on my Windows PC to get the same functionality.

Here is a way to break the file into 5 megabyte chunks:

# split -b 8m veryLargeInputFile

This instance splits veryLargeInputFile 8MB segments named xaa xab xac…xap.

Now put the file back together  at the distant end:

# cat xaa xab xac xad xae xaf xag xah xai xaj > veryLargeInputFile

or

# cat * >veryLargeInputFile

Note: ensure xa* are the only files in the directory when using the wildcard
For ASCII files: Split lines — This example splits a document into 1000 line segments.

# split -l 1000 veryLargeTextFile

Use the same process to put the file back together again.

Note: For larger files, find a ftp server or make your filesize increments bigger.

Split options

-b ##   — replace ## with the number of bytes you want in a file

-C ##   — replace ## with the number of SIZE bytes of lines per output file

-l ##     — replace ## with the number of lines per file.

-d          — use numeric suffixes for output files instead of alphabetic
