great tip for securing Last pass

Use a Dedicated Security Email Address

For additional security, you can have LastPass send security-related emails to a special security email address instead of your normal email address. For example, password hint emails, account recovery emails, and multifactor authentication disable emails will all be sent here.

This email should be an extra-secure email address only you know about – if someone gains access to your day-to-day email account, they won’t be able to access your LastPass vault without access to your security email account.

Visio objects not moving with arrow keys instead the whole diagram moves

Batch Image Editing in Linux

Must know for web developers. Many batch tools are available in imagemagick. convert and mogrify are both great! sudo apt-get imagemagick will get you going

bash$ for i in *.jpg
do
convert -scale ’48×38′ $i TN_$i
echo $i processed
done

mogrify -format jpg -quality ‘95%’ *.tiff (bulk-conversion)

For more optimized images use the following:

bash$ for i in *.jpg
do
djpeg $i | pnmscale -xysize 48 38 | cjpeg -opti -progr -qual ‘75%’ > TN_$i
echo $i processed
done
