I have only recently discovered that I could create Excel spreadsheets using VBScript scripts, but I knew I could embed tabs into my output and import tab-delimited files into Excel....
Over the years, I’ve written numerous VBScript scripts that used Excel for different purposes. I’ve found myself searching for segments of code from previously written scripts to reuse in my...

Of all the reasons to be rejected for a job, being told you’re “overqualified” really sucks. There are many reasons someone might look for a position that is “under their station” of what he normally would do. For example, managers who have had enough of the personnel issues that come up too often may seek a position that has no direct reports. Sometimes technical people discover they don’t like project management as much as writing code.
Microsoft released a patch for Bluetooth technology this month as part of the company's monthly batch of patches. While on the surface it seems like a significant risk, Microsoft says it's not really a big deal. Writing in its Security Vulnerability Research & Defense blog, the company stated that:
"First, since the issue is triggered over a Bluetooth link, the attacker would have to be within fairly close physical proximity to the target system.
Second, as the security bulletin states, the issue is triggered by a flood of SDP messages.
Finally, the attacker needs to find a way to control the memory layout of the target system, and place data they control in the correct location, all within the timing window mentioned above."
So there you have it: As long as no one is using a high gain Bluetooth antenna in your vicinity and as long as no one is smart enough to figure out how to manipulate things into an amenable state, you're safe.
Windows Server 2008 has a single-quorum model based on a number of cluster voting elements. By allocating these votes differently, Server 2008 clusters have four quorum modes.
Node Majority—There's no file-share witness or disk witness and votes are assigned only to nodes. More than 50 percent of the nodes must be available to make quorum. Node majority works best if you have an odd number of nodes. I recommend the Node Majority mode if you have an odd number of nodes, and you have a multi-site cluster, a cluster with no shared storage, or a single-node cluster.
Node and Disk Majority—Nodes and a shared disk get votes. This configuration allows a loss of half the nodes, providing the disk witness is available, or over half the nodes are available without the disk witness being available. I recommend Node and Disk Majority mode if your cluster has an even number of nodes.
Node and File Share Majority—The same as Node and Disk Majority, except the shared disk is replaced with a file-share witness. I recommend a Node and File Share majority mode if you have multi-site cluster, an even-node cluster, a cluster with no shared storage, or a two-node cluster.
No Majority: Disk Only—The disk witness must be available to have quorum, but the number of available nodes doesn't matter. If you have a four-node cluster and only one node is available, but the disk witness is available, you have quorum. If the disk witness isn't available, then even if all four nodes are available you can't have quorum. I never recommend the No-Majority: Disk-Only mode.
