Comment Save megatonnes of CO2 with this - & more! (Score 1) 167

Cool idea! You could save megatonnes of CO2 with this.

Suggestions:
1. Allow configuration of "absent time" before darkening screen
2. Provide link to OS Power settings
3. Allow configuring (auto/manual) of Hz of sound, from 16khz to system max
- to avoid any interference from other noise sources
- for kid/pet preference (BTW, my dog didn't notice - standard poodle)
4. Provide totals by day/week/... of different activity states.
5. Show timeline along display box
5. Allow stretching of display box and scaling of time line

Ideasfor further investigation:
a. use stereo speakers to determine how centred the echos are. Consider "absent from
        computer" (vs absent from room) if not both centred and close. You could allow a
        configuration setting for this too - "how centred / how close", e.g., a slider on the
        display screen, to compare with the graphs.
b. Use different frequencies within speaker/microphone ranges to "fingerprint"a room
c. Use "fingerprinting" to come to conclusions about what kind of room, e.g., bath stall,
        outdoors, small, large, busy, empty, dimensions- what can you discover
d. Use 2-speaker sonar to create a crude touch screen. (No 3d mouse since you need a
        plane to localise a point in 3D with only 2 speakers.) Could calibrate like on an old
        palm - push here, showing a X in various places.

You must have hit the beta-tester jackpot with a Slashdot reference!

Flash is still 10-20x the price for the same GB. Recent developments have increased max magnetic density 1000x current. While you may be happy with 128GB, think of what you could do with 128TB. Store all your HD movies, lectures, conversations, life. Keep all your web history, including pix and html. And then there's the "killer app" we haven't reached yet...

Comment You don't need much exercise to stay in shape! (Score 1) 865

Are you worried about weight or health?

For your heart, you need aerobic exercise 20 min/day 5+ days/week. So for lunch, run 20 minutes and eat while working. Or bike. Or climb lots of stairs. Sweat. Give yourself a sponge bath in the handicapped washroom if you have no shower available

For strength, you need to stress your muscles to the max 3x/week. Look up "body weight exercises" or join a gym or buy some elastic bands you can attach to stationary objects and stuff in your backpack or briefcase for portability.

But for weight, you just have to eat fewer calories. Switch to more fibre and less fat foods. Eat fruit for snacks, not pop or chips. Eat more vegetables, nuts, and seeds. Trim all fat/skin off your meats. Make eat smaller portions. Stay hungry until your weight is what you want.

Ideally, do both.
