Yahoo Mail offers the option to sync with Dropbox to save attachments to Dropbox. But the instructions for how to sync up don't accomplish anything, saving an attachment to Dropbox only results in an eternally spinning progress wheel and an empty Yahoo Mail Dropbox folder. At the same time I can save the same attachments to my computer with no trouble at all (Windows 8.1 / Toshiba Satellite). When selecting Save to Dropbox (from attachment list) I press Yes at the first inline popup window. The next separate popup window has two buttons neither of which do anything.

When I had Windows 8 I'd already figured out that Airplane Mode did the same thing as the Wi-Fi Antenna - Airplane Mode ON = Wi-Fi Antenna OFF and Vice Versa. Now that I've upgraded to Windows I see that Airplane Mode and the Wi-Fi Antenna now have their own individual switches, both in the Network Settings Charm. This is puzzling since they both do the same thing: turning on or off access to available wireless networks. Is there really any reason or advantage to having both switches?

Didn't mind the old one so much but the new one is purely irritating. I get it already, it's Yahoo. I don't need all this animation drawing my eyes to the logo.

Air conditioners create cold air by displacing the heat and sending it through the exhaust. So to cool the air inside we add heat to the air outside. The heat never really goes away. Heat is energy. Atoms vibrate as they heat up.

We invented the photocell that converts light into electrical energy. How would one design a device that could convert heat into electrical energy? A plus would be if the process actually removed the heat from the source material - presumably the air. A device such as this would have to advantages"

1. Production of energy that is clean and cheap

2. The next-generation air conditioner that only cools air with out sending hot air out the exhaust the way current air conditioners do..

The person who invents this would make billions.

The Yahoo Answers spell checker is claiming I have a lot of spelling errors when in fact I have none. It highlights words, correctly spelled, then provides an empty correction list.

At the very bottom of the page is three characters "); a double-quote a right-parenthesis and a semi-colon. This is an obvious bug in one of the scripts that make up the Yahoo Mail page. It means something is not working somewhere, but it's not something obvious, so what is it? Is it somehow related to the fact that my color Theme settings are never saved?

Yahoo Mail always opens to an ugly dark-grey and orange color theme. I can change the theme manually, but it is never saved even for the current session because each time I return to Yahoo Mail it defaults back to the ugly dark-grey and orange Theme. The selection bar color setting is white text on bright orange, which is impossible to read. This is an obvious screw-up and it is very annoying. Even MyYahoo works better than this. What gives?

The problem with nuclear energy is it leaves behind nuclear waste in the form of spent fuel rods that remain radioactive for thousands of years and must be stored very carefully to prevent a disaster like the ones we've seen in Japan and Chernobyl. But disasters aside, just the very cost of storing this waste must be getting expensive, more so every year since the waste never goes away and remains a permanent issue. So I thought, what if we figured out how to shoot the nuclear waste into outer space. Aim it at nothing or the furthest star we could locate. Since it would take millions of years for the nuclear waste to get there, the radiation should be completely spent by then and would no longer be a danger. So the questions is: is it feasible? Is it cost effective when you weigh the cost of shooting it into outer space once against storing it on earth indefinitely? And what is the risk of unintended consequences?

HEAT is energy trapped in atoms and molecules, making them vibrate. Everything we humans do results in heat. Our roads and buildings absorb heat during the day and release it at night. Power plants, cars, planes. Electronic devices such as computers, TVs, cell phones, etc. Even our refrigerators and air conditioners produce heat as a byproduct. Only photo-cells and wind turbines can produce energy while being comparatively neutral in heat production. So here's a brain teaser. Is it possible to design a device that does the opposite, that not produces energy,but does it by absorbing heat during the process, resulting in cooling the air and objects around them? If so, think of the benefits. Power plants, cars, etc. that have the side benefit of cooling the air around them. If used widely, a device like this could potentially balance out or even reverse the global warming effect that our technology, our very presence has on this planet. I know that this idea sounds very counter-intuitive. Activity, biological or mechanical, normally produces heat, according to the laws of thermodynamics. As we all know, heat is everywhere on this planet, and nearly impossible to get rid of. So what if we could put it to use? Reverse the process that created the thermal energy in the first place by converting thermal energy into an energy resource such as electricity. It sounds very science fiction, but heat is a real thing, compared with cold. Cold is just nothing, the absence of heat. Since excess heat is the most plentiful (and currently unwanted) thing on the planet, why not figure out how to get rid of it by converting it into something useful? The person who figures out how to do this, and patents it could get rich. All you physicists out there, think about it!

IE9 is ok, except that it always starts with this annoying dialog "Speed up browsing by disabling add-ons" Its completely unnecessary and annoying. What so I have to do to turn off this dialog permanently?
