Total Lunar Eclipse

Did anybody get to see the lunar eclipse this morning? It occurred just after 5 am in this part of Colorado. I was outside with my binoculars. It was amazing! The light traveling through Earth’s atmosphere actually made the moon appear to be deep red in color, before eventually leaving totality behind the clouds as the sun came up. Good stuff!

Also, there’s a meter shower coming up on August 31st that shouldn’t be missed!

Fix Activesync Error 0×85010014 on Motorola Q

Okay, so you’ve applied a new GoDaddy SSL certificate to your Exchange webmail site in IIS. Everything looks great and you’re ready to rock. You enter server information and credentials in the Q and hit sync, but instead of seeing your inbox, you’re presented with error code 0×85010014 and something about an invalid server certificate. Wonderful.

If you’re worried that your certificate is broken, relax. It’s probably fine if you’ve followed the installation instructions accurately. The problem as it turns out is with IIS.

Unlike the Samsung Blackjack which uses a form of OWA (or OMA), the Q uses Activesync and negotiates security a little bit differently. I’ll refrain from getting into details, but save yourself a lot of time and read KB817379 over at Microsoft.

Repair an Outlook OST Mailbox File

Sometimes when Outlook is setup to use Cached Exchange Mode, the offline file which is created on your local disk can be corrupted from an improper shutdown of Outlook, among other things. When this file contains errors, it will greatly diminish Outlook’s performance and in some cases prevent it from starting completely.

There are two things you can try.

  1. Repair the offline file with a Microsoft utility called SCANOST.exe. I’ve seen this file reside in a number of different locations, mainly within Program Files. It might be best to search for it with Windows or Google Desktop. SCANPST.exe will also work, though you’ll have to go digging for your outlook.ost, which should be near c:\Documents and Settings\ %profile%\ Local Settings\ Application Data\ Microsoft\ Outlook\ outlook.ost. If your file is significant in size, you’ll save a lot of time with the repair operation by not creating a backup. Because if the repair finishes successfully and Outlook still bombs, you’ll need to;
  2. Shutdown Outlook completely, including any runaway outlook.exe processes in the task manager. Open Mail in the Control Panel and before you delete your profile completely, write down the server settings! There’s no need to worry about backing up your mail as it’s stored on the Exchange server. (Essentially, you’re deleting that outlook.ost when you drop your mail profile.) Now, start Outlook and it will create a new profile, where you’ll configure the server with the information you wrote down previously.

Outlook will start normally again.

Disable SuperFetch in Vista

In theory, SuperFetch in Windows Vista is a seemingly good idea. Though as it pans out in real world performance, it can be responsible for a lot of unnecessary disk activity and performance degradation. (Though, you probably wouldn’t be running Vista if you were the least bit concerned about performance in the first place.) Essentially, it robs Peter to pay Paul by caching files and programs it “thinks” will be needed in the future, in an effort to reduce application startup times. But more often than not, this caching of data hinders performance significantly. Especially if you have a notebook with 1 gig of RAM or less. Vista strives to use every last bit of system memory available to increase performance.

There are other features available to enhance the performance of SuperFetch and decrease the lag of intensive disk swapping, such as ReadyDrive, but I’ll save that for another time.

Turn off SuperFetch by clicking on Start > Run > type in ‘services.msc’ and scroll down the list until you see ‘SuperFetch’, right-click, view properties, change the status to ‘stopped’ and the startup type to ‘disabled’.

This is not recommended unless you are seeing major performance issues as a result of violent disk thrashing.

Rebuild the YUM Database in Fedora 7

If you’ve ever gotten to a point where installing RPMs in linux becomes unresponsive, unreliable and/or extremely flaky, you may need to dig a little deeper. Simply killing the yumex/yum/python processes may not be enough. Perhaps a reboot will do the trick, but when you run a server, any downtime whatsoever is unacceptable 99.9% of the time. Your next option–rebuild the RPM database. YUM will (should, rather) then function normally. Do so as stated:

[code]rm -f /var/lib/rpm/__db*
rpm --rebuilddb
yum clean all[/code]
