Due to an error in the checklist manual, the rendezvous radar switch was placed in the wrong position. This caused it to send erroneous signals to the computer. The result was that the computer was being asked to perform all of its normal functions for landing while receiving an extra load of spurious data which used up 15% of its time. The computer (or rather the software in it) was smart enough to recognize that it was being asked to perform more tasks than it should be performing. It then sent out an alarm, which meant to the astronaut, I'm overloaded with more tasks than I should be doing at this time and I'm going to keep only the more important tasks ; ., the ones needed for landing ... Actually, the computer was programmed to do more than recognize error conditions. A complete set of recovery programs was incorporated into the software. The software's action, in this case, was to eliminate lower priority tasks and re-establish the more important ones ... If the computer hadn't recognized this problem and taken recovery action, I doubt if Apollo 11 would have been the successful moon landing it was.  [a]
TASTE TEST AWARD: Amy’s Kitchen. Topped with organic tomatoes, whole-milk mozzarella, and lots of basil, this one is a thin-crust-lover’s primo pick. Advertisement 11 of 27 Photo: Manfred Koh Tortilla Chips (100% yellow corn) GRAND PRIZE WINNER: Target Archer Farms Organic. They’re corn-yellow-pretty, delectably crunchy, nicely salted, and loaded with hearty flavor. Plus, a zip-top bag closure staves off staleness (if they last long enough for a third or fourth session).
Before placing an order, you might want to know what it will cost to go this route. Typical prices for concentrate are $8 to $14 per quart, $7 to $10 for pints, and $3 to $4 for 4-ounce bottles. Shipping will be expensive—count on an additional 30% to 70%, depending on how much you order and the distance. Depending on these factors, flavoring costs are likely to range from $ to $ per liter. Obviously, at the high end you won't be saving much if any money over SodaStream's flavors, once you add in the cost of sweetener; but if you can buy a few pints or quarts at a time, the total cost (concentrate plus sweetener) will fall in the $-$ range. Most or all of the ingredients will also travel less than the SodaStream bottles, and what does travel will mass less, which all adds up to being better for the environment.
