7/26    I'm looking at Dell Latitudes, and there's an option for a 65W AC
        adapter vs. a 90W adapter which is $19 more. It doesn't give any
        explanation for what the higher wattage would be good for. The only
        thing I can think of that seems reasonable is if you want your
        laptop to power large USB devices or something. Can someone clue me
        in? Thanks.
        \_ The USB spec only allows something liek 5W of power to be sent over
           any single link of the bus.  The 90W adapter it probably so you can
           charge your battery faster, or run your laptop at full power and
           still charge the battery at full speed.
        \_ You might replace your HD with a faster/more power consuming one
           later, etc.
           \_ For thermal reasons you might not want to do that in a laptop.
        \_ http://csua.org/u/8by
           65W doesn't work with Latitude D800, but the 90W works for all.
        \_ I would urge you to look at the size of these things, and choose
           the one which is lighter and smaller, ignore the wattage
           requirement.

8/29    I have 2 AA rechargeable batteries. One is at 300mAH and the other
        one is at 600mAH. They used to be 2400mAH. Is there anything useful
        I can use them for?
        \_ How do you know this?

8/16    I just left my employer. They didn't ask to get their HW back.
        Is is common for employers to contact me a few months/years later
        and ask for their HW back?
        \_ Is it an iPhone 9 prototype? :-)
           \_ as a matter of fact, it is just a 2 year old laptop

7/8     Suppose I just stopped going to work and stopped communicating
        with them. How many days will it take before they stop sending me
        paycheck (and maybe even try to get back the laptop they gave me)?
        \_ They'll probably try to call your emergency contact first to see if
           you're hit a tree or something.
           you've hit a tree or something.

12/21   In Emacs, how do I make it so that it will resize its screen
        when the maximum resolution of my monitor changes? When I
        use my laptop, my emacs is too big (and I can't resize it
        because the bottom-right corner is not accessible).
        \_ Which OS?  Can't you drag the top border (not a corner) to resize
           the height to be smaller?

5/4     Any thoughts about apple switching to ARM for all machines?
        \_ Could only have happened if the Mac App Store had been a wild, wild
           success, and they were willing to give up Steam. Games/dual-booting
           is strategically valuable to not driving people away from macs.
           A new ARM iOS based device, or opening the Apple TV to iOS apps
           (same thing, really) would be much more likely than sabotaging their

3/12    I am curious what others think of tablets like iPad. They don't seem
        useful to me, but I use my computer for more than web browsing,
        Facebook, and Twitter. Why would I buy one instead of a laptop?
        They seem like a disabled laptop to me, but at a higher price.
        \_ You are most likely a coder.  iPad is not for coders.  They are
           what you get your non-technical friends.  Or musicians.  Look at

9/21    are you guys really all using win7 in some way now?
        \_ Yes.  In my company, we have upgraded all our machines for
           development, QA and other office use (HR, Finance, Receptions, etc.)
           from WinXP to Win7 a few months ago.  Our products now primarily
           support Win7/Win2008 and secondarily support WinXP/Win2003.

5/13    I am getting a new Macbook Pro. Should I get a glossy or matte screen?
        I always had matte in the past. I use my laptop just about everywhere
        and glare is a concern. Should I stick with matte? I noticed
        glossy is the default now.
        \_ It is weird, but I have the glossy screen that goes to the edge of
           the monitor for my 13" PB and it somehow seems bigger than the one

4/4     My macbook is dying. After three and a half years, I want to retire it,
        and get a new one, but I live in constant fear* that Apple will pull a fast
        one on me and update them as soon as I do. Anyone know anything about an
        impending Apple laptop refresh?
