HOWTO get business days between two dates using TSQL
DECLARE @TotalWorkingDays INT
DECLARE @StartDate DATETIME
DECLARE @EndDate DATETIME
DECLARE @CurrentDate DATETIME
...
SET DATEFIRST 7;
WITH CTE_DatesTable
AS
(
SELECT DATEPART (dw,@StartDate) as [dn], @StartDate AS [date]
UNION ALL
SELECT DATEPART (dw,DATEADD(dd, 1, [date])) as [dn], DATEADD(dd, 1, [date])
FROM CTE_DatesTable
WHERE DATEADD(dd, 1, [date]) <= @EndDate
)
SELECT @TotalWorkingDays = COUNT([dn]) FROM CTE_DatesTable WHERE [dn] NOT IN (7,1)
OPTION (MAXRECURSION 0);
SELECT @TotalWorkingDays
What happens with this query is that it counts the days between the start and end dates excluding Saturday and Sunday (7 and 1 using DATEPART with the dw argument).
Note: this query does NOT take in to consideration any holidays.

HOWTO install Oracle Solaris Studio 12.3 (release version) on Solaris 11 11/11 using pkg (not tgz)
Oracle has finally released Oracle Studio 12.3 to the public, but with one persistent gotcha that was present in the Beta: it isn't (yet) available to install using pkg on Solaris 11. I decided to figure out how to unravel the shar for Solaris 10 so that pkg could install 12.3 and it's a lot more difficult than the Beta was. To give an overview of the process you have a shar that contains a giant .jar file inside it. Once you get that .jar then you can unzip it and you will discover a bunch of .class files plus .jar files with names such as data1.jar. These .jar files actually have the IPS files needed for use with pkg.
The first problem that needs to be overcome is getting the main .jar file out of the downloaded shar. The problem here is that Oracle has made the shar so it detects both the version of Solaris being run and modifications to the shar itself. Since the shar is just a giant shell script it's actually very easy to bypass both.
Step 1: Modifying the shar
Open the shar that was downloaded from Oracle with your favorite text editor (after extracting it from the .tgz). Now modify the following:
Line 113: EXTRACT_ONLY=0
to:
EXTRACT_ONLY=1
Comment out lines 229 and 870
run: sh ./solarisstudio.sh
Step 2: Getting and installing the pkg files
unzip bundle.jar
There will now be a directory structure that's a mixture of .class and .jar files. We are only interested in the .jar files. Make a directory (e.g. mkdir ext). Now: cd data ; find . -name *.jar -exec unzip {} -d `pwd`/../ext \;
cd ../ext ; find . -exec pkgadd -d {} \;
Oracle Studio 12.3 will now be installed in /opt/solarisstudio12.3

Notes on upgrading to Solaris 11
This is just a posting about the snags I encountered while upgrading from Solaris 11 Express to Solaris 11 11/11. The biggest problem that I encountered is that I simply could not upgrade using the package upgrade utility. It would install everything fine, but once rebooted grub would complain about a missing kernel (which has a Xen label buried in it). So I decided to try to use Oracle Solaris 11 11/11 Automated Installer. That would be mistake number 2.
The automated installer not only blew away all my partitions, but, I discovered painfully, is missing more than half the packages needed to get X running (note to Oracle: I hate you). My first thought was to download the repo images on the download page and the missing binaries would be on there. No go.
The solution to getting X working on Solaris is making sure your network connection works (at least the automated installer got the config files right - mostly) and using pkg list -a. You will need to install practically everything remotely related to X including the themes and the display drivers (why does an over the wire automated installer NOT do this for me?) before you can get X working. Once you've got the X working you can then leisurely install any and all remaining packages using the graphical installer.

HOWTO install Oracle Studio 12.3Beta on Solaris 11 using pkg (NOT tgz)
The normal installer is broken so installing via GUI is not possible. However, I did some digging and a bit of guesswork which resulted in me finding the solution. The first part of the solution is to extract the installer files from the shar that you downloaded from Oracle (SolarisStudio12.3-beta-solaris-x86.sh in my case) which is accomplished by running: sh ./SolarisStudio12.3-beta-solaris-x86.sh --extract-installation-data .
This will result in 20 different files being unpacked in to the current directory. To install them you need to call them using: pkgadd -d filename. Filename is replace by each of the 20 files such as cc, c++, etc.
Kudos to Tech-Recipes for the pkgadd command. http://www.tech-recipes.com/rx/350/install-a-solaris-datastream-package/

HOWTO get Drivel working with Blogger/Blogspot
===================
blogger.com does not work as Blogger 2.0, only as blogger 1.0. I've just tested this: http://drivel-dev.blogspot.com/2010/07/another-test-for-blogger-10.html Change to Blogger 1.0, drivel will then select: http://www.blogger.com/api/RPC2 for the server address.
