Chess Game with Built-in Tutor?

In 1996, Sierra released a program called "Power Chess" for Windows 95 and 98. It was based on the WChess engine and had a fantastic teaching mode. Your primary opponent, the King, would learn from you as you played. Games would get progressively harder as he tailored his strategy around your weaknesses. Once each game against him ended, you could play it back move by move and the "Queen" would explain his strategy and suggest how you could have played differently. Power Chess is no longer supported by Sierra/Activision and won't run on Windows 10. Does an Android or Windows equivalent exist? [more inside]

Printing photos in the woods

As part of an art project, I would like to be able to use my Canon Selphy CP910 portable printer to print about 30 4x6 prints while at a remote campsite for 5 days. I was thinking maybe I could get a portable, rechargeable UPS like this. How do I figure out how many prints I can get out of something like that? Is that the best option? [more inside]

Computer noise at startup

I bought this computer off an Ebay store where they assemble it for you. On cold mornings, it would make noise after turning on (power supply fan related). The noise would stop for a while. I got a replacement power supply (PSU) from the company and the noise stopped for a while. Now it's almost summer, it's not that cold, and the noise has started again. I'm thinking maybe it's not the PSU but maybe the flimsy case enters some resonant vibration? With the previous PSU I tried to buffer the spaces between the case and the PSU with tape, didn't do anything. With this new PSU, I tried to tighten the screws again, didn't do anything. I'm sure the noise isn't coming from the case fan, as, when I had the previous PSU, I disconnected that fan to make sure.

Word that means assumes power without justification

I’m trying to recall a word I’m fairly sure exists. It means to assume power (over a particular domain) without justification. Like “accroach” but specific to power. Except I don’t think it’s a verb, I think it’s an adjective that can be applied to a person to describe their behaviour (with negative connotations). So one could say, “When he took it upon himself to create rota for washing dishes, even though Graeme is responsible for the kitchen, Mike showed himself to be a ______ individual.” Though I don’t think implications of usurping are required.

It's electric.

I wish to adapt. I have this zappy shocky thing, which works with either 9V batteries or a wall adapter. Unfortunately, even with good 9V batteries it does not last very long, and the wall adapter does not charge any rechargable batteries in the unit. I would like to use something like external phone batteries to keep it active for longer periods of time when not near a wall outlet. [more inside]

Remedial economic theory

I've had this concept in my head that I'm pretty sure I picked up in economics/management studies but I can't recall its name: The division of labor between an executive and her direct support staff is that staff can advise the executive about decisions to make, but ultimately she makes the decision and they then have to carry out that directive or policy (regardless of whether it's justified in their opinion). I had assumed I was thinking of the principal-agent problem, but that's clearly something else. What is this concept called?

Physical Sensation When Driving by Electric Utility Fault/Arc?

While driving home from work yesterday afternoon during somewhat-cloudy daylight, I suddenly noticed a bright bluish glow on nearby objects, heard a loud hum that sounded like it had 60/120ish Hz components, and felt a strange tingling/vibrating sensation in my upper body. When I got home, I checked the power company's outage map and saw that there was a ~500-customer outage centered around the area where this happened, which started around the time I drove through the area. The stated cause of the outage was "equipment problem." Because of this, I am guessing there was some kind of fault in the roadside electric distribution system which caused all of this, and I have some questions about what might have happened.

Home Power Generator Question

Every summer and winter, random weather related power failures (as well as those caused by people knocking down power poles - it's rural with lots of winding roads) leave the house without power for hours to days. So I'm thinking about getting a Generac 8kw gas-powered portable with a manual transfer switch. A Generac 10kw propane powered installed with an automatic transfer switch is at least 6 six times more expensive and I don't see much of an extra benefit. [more inside]

Using American electronics in Japan

Hi, I am moving to Japan soon and I can't seem to find a definitive answer on whether or not my various electronics will work in Japan. I was hoping to move my tv, speakers, consoles, and AVR but most of them are rated at 110-120V and Tokyo is rated at 100V. I have read articles saying it is fine and other saying the opposite. Can anyone point me to some credible source to help answer this question? Are there other things I need to look into besides voltage? My understanding of electricity is abysmal.

How do dams hurt rivers, exactly? Is that damage built in – that is, are there ways to mitigate it? On the other hand, do a few million people deserve electricity? Looking for reasoned arguments.

No power to car stereo or starter

While installing a new car stereo in my 1999 Saturn SW2, I screwed something up, as I no longer get voltage to the orange "constant power" wire (well, sometimes a mere hundredth of a volt!) to my car stereo, and my engine won't crank either! Yet all of my other electronics (headlights, air conditioner, etc.) work fine. Is there a blown fuse preventing power from getting to the starter and the car stereo? If so, where might the fuse be? The fuses in the fuse box are all fine.

Oral B electric toothbrush charger compatibility

I currently own an Oral B electric toothbrush with charger unit #3757, 110-130V, 1.3W. I'm moving to Malaysia soon which has the 240V/50Hz power, so I got someone to bring me a new fancy Oral B from the UK which has the same electric supply. This comes with a charger that is also labeled #3757 but says 220-240V 0.9W. So my question is, can I safely charge the new toothbrush with the old charger until I leave the US? Or will the slightly higher powered charger fry it?

What motivates electric companies to repair the power lines?

I don't really understand the utility industry very much but I've noticed some electric companies are very responsive to getting lines up from damage and have crews out at 2 a.m., and others don't even start work until the next day.

Or is there some sort of precedent in litigation that would put them at fault for underperforming? [more inside]
