Beware of undocumented machine code instructions

Greetings.

Jewish date:  29 ’Elul 5769.

Today’s quasi-holidays:

Worthy cause of the day:  “AmericaCantWait.com” and “Take Action: Colorado's pristine forests need your help today!”

Today’s news and commentary:

• “Underwater Suffering: Do Fish Feel Pain?”
• “Old Operating Systems Don’t Die…”:  CP/M still alive?  Who knew?

Today’s weird thing is the machine code instruction “Halt and Catch Fire”.  Enjoy, share the weirdness, Shabbath shalom, and may you be written and sealed for a good year.
