When looking at Chromecast, I came across mentions of Miracast a few times, which I’d never heard of even though it has been around for a while. Like Chromecast, Miracast is a dongle that plugs into the HDMI port of a TV and acts much like a physical HDMI connection.

Am I shortening my battery life or causing any harm if I leave my laptop always plugged in?

I got a refurbished Lenovo laptop recently, and one of the keys on the keyboard isn’t working. I blew it out with canned air, and there was almost nothing in there, so I don’t think it is a bit of dirt causing the issue. Any suggestions on how to troubleshoot this problem?

Could you just do a system restore to a point in time before the problems occurred?   

Yes, just hold down shift when you insert the CD/DVD/whatever. Super easy. 

I watched the YouTube promo video for Chromecast, the new device from Google that plugs into the HDMI port of a television. Ok so far. Then I see USB powered. Then it basically looks as if the people in the vid are pulling up content on their laptops and watching it on their TV.

While getting my daily serving of red pandas and cats on buzzfeed, I ran across an article about protesters unhappy with Nintendo because they felt the company was doing too little to ensure “conflict minerals” (raw material from exploitive/violent places like mines in Eastern Congo).

I am most excited about the calendar addition at this point. Seriously. However, I assume there are more substantial changes, and I’m not talking about the “Start” button, which I could not care less about. Any major changes?

One reviewer on Engadget  reported about 5 hours of battery life during what he characterized as normal use, including taking a few photos/videos and reading emails.

We will probably learn specifics of release and retail price at Google I/O, and I am really curious where they will be priced. As was already pointed out, the current $1500 is not realistic for general sales. The hardware doesn't have a lot of really exotic components, so I would expect that price to come way, way down.

I have a personal blog, and I would like for it to do reasonably well so that I could eventually make a few bucks from it (don't worry, I'm not going to post a spammy link to it in my question). One thing I'm uncertain of is what bounce rate I should be looking for. What bounce rate would be considered good/acceptable for a blog?

It's kind of like jeopardy, except you ask the question first and there is no prize money.
