Under some re-construction as of 10/10/11. New look and layout, couple things I need to fix. :)

General Tech Notes

Kingston-G3-SpeedIn case anyone is wondering about buying Kingston Datatraveler G3, they are not as fast as the OCZ Rally 2 series, but write speed looks to be 10-11 MB/sec.  Good for the price at around $11 for 8GB.

I was hopeful for the Motorola Xoom.  Oh well.  Don't get me wrong, it will sell well because they are pushing them via Sam's club, plus all the people who have been unwilling to deal with Apple's draconian walled garden.  It is a nice device, fast, clear screen with better resolution than iPad ( I still don't get the glossy screens, sexy but mirrors ), but it's not ready for prime time.

Motorola-Xoom-tabletI love Android, but I still use an iPhone.  The iPhone works better with exchange and seems more predictable in what it will do.  I get annoyed with iPhone and I sold my iPad because of the crappy screen, horrible ergonomics, and stupid charging problems, but their iOS is more mature.

The first thing everyone said when they picked up the iPad was, "oh, it's heavy".  When people pick up the Xoom they said "oh my god, it's heavy".  It's only a bit heavier than iPad but it feels as heavy as a laptop.

Everyone agreed it was very fast and the screen was clear.  The wierd part?  No apps.  Ok, 15 usable ones, but why put Android 3.0 on instead of 2.2 like on the Galaxy tab?  Plenty of apps for Android 2.2.

So apps will come out, and they will sell a bunch, but it made me reconsider.  I was going to move from iPhone 3GS to Android Infuse 4.5" this year, but now I am thinking about just waiting for iPhone 4G or 4S or whatever they decide to call it once they get over their design compromise issues.

If you are running Lenovo Thinkpad T400 with more than 4gb of RAM and Windows 7 and discrete graphics, you may have a problem with video corruption when running with the integrated Intel video adapter / energy saving, but not with the ATI.  I found that it worked fine if I had less than 4gb of RAM.  The workaround to make it work with more RAM is a bios setting.  You can enable the virtualization hardware, but not the virtualized I/O.  With the vm I/O turned off, it works fine with lots of RAM and either video adapter.

Update: I think this only happens with 6gb ram ( 4 + 2 )

A SSD (solid state drive) is the best investment you can make to increase the performance of your computer.  ( in a sign of getting old ) I have the habit of always making a fixed pagefile ( swapfile ) on a secondary hard drive for an extra performance tweak.  Traditionally this was faster because when the operating system decided it needed more RAM and began to swap parts of RAM to the hard drive to make room, it left the primary drive open for reads and writes.  The second part was to make a fixed size swap file rather than a dynamic swap.  This allowed you to put the swap file on the outside of the platter ( first ) where it had the maximum transfer rate and prevented fragmentation for faster random access.

While this general practice still might make sense for a second drive, if the drive is an SSD, it may occur a pentalty as it ages.  

SSD ( solid state drives ) have no moving parts and random access is fast because there is no delay waiting for the right part of the platter to come around.  Their disadvantage comes in a limited number of writes per memory cell.  To work around this, the drive does not always use the 'first' memory cell for writes.  If you erase a file, then write another file, it will try to use the 'least used' memory cell to average out the lifespan.

So in the case of a SSD and pagefiles, it may make more sense to let the operating system dynamically allocate the pagefile.  I don't know enough about how the fixed page files are initiated on a reboot, so it may not matter.  Either way, I don't really see a reason to make a fixed page file anymore.  YMMV.

Facebook recently started to support XMPP, the same communications protocol used by Jabber and Google Talk, in their Facebook Chat product.  I assume voice chat is coming and with all the netbooks with cameras, hopefully video chat soon too.
