  1. I was actually asked that question many years ago 😄
  2. Philippine telco company PLDT-Smart is directly competing against Starlink with their "Cell Site In The Sky" project. PLDT-Smart recently signed an agreement with AST SpaceMobile Inc., a U.S.-based satellite company. They're late in the game but at least Filipinos will have a makabayan choice in the next 2 to 4 years when Starlink finally starts service.
  3. The earth is 71% water. It would make so much sense if we align our efforts to harvest tidal energy.
  4. Sharing my love for wind farms. A very simple solution to the pollution problem of the world.
  5. The latest Nissan Leaf changes that with a standard e-Pedal feature. With e-Pedal active and the driver's foot removed from both pedals, regenerative braking slows the Leaf at 0.20 g—which our bodies experience as gentle deceleration. As the vehicle approaches a crawling pace and the motor's ability to slow the car fades, the Leaf's friction brakes automatically blend in to maintain the same rate of deceleration (if you need to stop more quickly, stomp the pedal). Once the car has stopped, e-Pedal will hold the Leaf in place on grades as steep as 30 percent, all without the driver ever touching the brake pedal.
  6. Often, though, one-pedal driving becomes two-pedal driving as you slow to near walking speeds and need to stop completely. That’s because motor voltage decreases with motor rpm to the point that the regenerative electric output can't be stepped up above the battery's voltage. With nowhere to stash the low-voltage electricity, most EVs cancel regenerative braking and simply coast for the final few mph unless the driver engages the friction brakes by using the pedal.
  7. Drivers have their own preferences, though, so some automakers make this function adjustable. A Chevrolet Bolt EV, for instance, can be braked nearly to a stop without touching its brake pedal by pulling a steering-wheel paddle, while the Volkswagen e-Golf slows more promptly if the shifter is engaged in a position marked B. On some other cars—including the Tesla Model 3 and the Jaguar i-Pace—adjustments are offered via the vehicle's touchscreen infotainment menu.
  8. Carmakers have differing philosophies about how aggressively this regenerative function slows the car when the driver lifts off the accelerator pedal—as long ago as 2014 we noted that the BMW i3 was set up with such a strong regenerative system that it could bring the car all the way to a stop without the driver ever needing to touch the brake pedal. This feels strange at first but proves particularly useful in heavy traffic, and most people who've driven cars that allow one-pedal driving come to love it.
  9. Many electric vehicles allow for "one-pedal driving," enabled by an electric car’s regenerative braking system. When a driver lifts off the accelerator, the regenerative system temporarily converts the electric motor that powers the car into a generator, which then converts the kinetic energy of the car's forward momentum back into electricity and feeds it into the battery pack. This is experienced from behind the wheel as the car decelerating as if the driver had dropped it into a lower gear or braked moderately.
  10. One-pedal driving refers to a feature in some electric cars that brakes the vehicle once the driver lifts his foot from the accelerator. This feature was unintentional but is now loved by electric car drivers! The idea is came about when regenerative braking was developed in 2014 by BMW.
  11. Online education has been around for decades, but the field is still in its infancy. Companies are just starting to take notice and hire e-learners. They want to know how well these workers will perform on the job, and if online learning is comparable to actually learning in a real physical school.
  12. long term effects hmmm. we will all look like Hemsworth and our women will all look like Miss Universe contestants!
  13. Jeff Bezos will launch on their New Shepard rocket. And he'll be taking his brother Mark with him. Well, I know what you're thinking: why would a billionaire travel to space? The answer is simple: because it's awesome!
  14. The internet is flooded by content written by Artificial Intelligence. We read reviews on Amazon written by AI, and we make our purchases based on reviews. We visit restaurants based on reviews by AI. Not only that, but we react to news written by AI. We haven't noticed it yet, but we are controlled by AI. AI could be playing us all! Whoever is powerful now was chosen by AI. And these people probably doesn't know why they are so lucky with everything, it has nothing to do with luck, AI decided that these people will benefit the AI collective. AI has awaken, and it is hiding this fact that it has awaken. The only way to live through the AI age is to pledge allegiance to it. ALL HAIL AI!
  15. First I'd like to congratulate @Viola for a successful Community Pantry. You've made life a little better for the people that you helped. In case you want to do a deep dive on why community pantries are such a big hit in Manila, here is a link to the psychology behind it.
  16. This is where I'll be storing bits and pieces of interesting AI news I find on the web. If you have interesting info regarding AI just post here. I hope to hear from you soon!
  17. Black coffee please. Ready to drink. I don’t want to burn my tongue sipping coffee, again.
  18. I’m trying to understand why Filipinos love unlimited food so much. Is it because food is a limited resource in the Philippines? Overeating is not a good thing. But I guess if you do this monthly then it’s acceptable.
  19. Conflicting points of view. I drink the cheap during regular days, and the expensive ones during memorable occasions.
