So to a business owner, _no_ commodity is more valuable than feedback.

People have a bad meal at a restaurant, and 90% of the time, leave without saying a word. The business owner is perplexed, and eventually goes out of business.

"The roast beef here is terrible."

Six words could have saved his business.

The same is true for every business.

AC is certainly free to stop reading, and AC knows that. You're not really adding to the conversation, but you could dissuade them from providing an extremely valuable service to businesses in the future - feedback.

Comment Re:Antennas (Score 4, Interesting) 215

It's not really a mystery. Phones used to have external antennas, and now they're not only internal but the phones themselves have mostly metal cases (because it feels so much more "premium") with a tiny plastic window for the antenna because that metal blocks the radio waves. This is textbook "form over function" design.

I'm with you against the whole form-over-function bullshit that's swept the mobile device world in the last 10 years, but I wouldn't necessarily call out internal antennas as the problem.

For one, frequencies are higher permitting smaller antennas. Voice channels are digital, and compressed, meaning lower data rates. And, quite frankly, if you can support data at megabit levels (which you can even at like -100dBm), you can support 44khz/16bit voice, let alone the unbelievable low bandwidth codecs we use.

I think it has more to do with the simple fact that people don't use voice as often, and manufacturers are putting their development effort elsewhere. This leads to problems like incorrect microphone placement, non-functioning noise cancellation, radio firmware bugs, poor process priority management, etc.

In the old days, I'd choose a phone based on how well it made calls. Now, it's literally the last thing I check, if I even check at all. Screen quality, data rates, processor performance, storage and RAM, internal sensor array and battery life are all far more important to me, and I suspect this is true for many, if not most. Even if it's not true, I think it's what manufacturer market research suggests, and so we are where we are.

Assuming a linear-ish discharge curve over a 70% discharge, 1.44Wh D cell to 18.5Wh (equivalent) C cell is not a 2x capacity increase.

I want battery technology to increase an order of magnitude every year too, ... but come on. We've made enormous strides.

You, yourself, can buy low-resistance, low-self-discharge lithium ion batteries at 250Wh/kg. And they're cheap. Compare that to 30Wh/kg NiCD batteries of 30 years ago.

50% of climate change gasses (methane and CO2) come from the production of meat.

So, food is (mostly) a closed cycle. While the chemical reaction that creates methane is a problem (as methane is a much more effective greenhouse gas than CO2), all of the CO2 released by us and the animals we eat comes from, ultimately, CO2 captured by plants.

Cows eat grass (or corn.. sigh), and new grass grows, capturing CO2.

Comment Reduce energy consumption by 90%? (Score 2) 173

Aside from being unachievable, we should be asking ourselves as a species: is it even a good idea to try?

The amount of energy we "use" (ie. convert) today will register as noise relative to what we will be using in 1,000 years from now (should we survive). We've reached the age, as a species, where we need to be focusing on the long-term, as well as the short-term. If we're to survive past the next mass extinction event, we're going to have to keep the technology advancement train a'rollin. There is no going back, and there's no reason to go back.

We should each strive to reduce our impact on the planet, our resources, and each other. We should build efficient machines, and use them efficiently. We should stop burning coal, gas, and oil, and generate our electricity through a blend of hydro, nuclear fission, solar, wind, and geothermal. These are all short-term achievable, and healthy for our civilization.

But we should not be compromising our ability to convert enormous amounts of energy, nor the effort we put into developing this technology. For one day, we're gonna need it.
