Mobile Browsers

While researching on usage of Mobile Browsers, came across two interesting sites

2. Mobility checker

Logging and Performance.

What is the impact of logging on performance? If my ASP.NET website logs information about requests to a log file, the log file will turn out to be a resource that will get concurrently accessed. A lock placed on the log file will significantly impact ability of the server to concurrently process requests. Logging frameworks like log4net handle this very smartly.

5. tf status: To check who has checked out a file Default.aspx, run the command
tf status Default.aspx /user:*

SqlBulkCopy vs SSIS Bulk Insert

I recently wrote a program to move data from a CSV file into a SQL Server table using SqlBulkCopy.
The CSV file had data like
0,0,35.6,-122.5,1,
0,1,35.61188,-122.4438,1,
0,2,35.61979,-122.4062,1,
.
.

Below are some of my observations.

Trailing Delimiter Handling
With SqlBulkCopy, the data was successfully moved to SQL Server.

But when I used the SSIS Bulk Insert Task, the following error was reported

Bulk load data conversion error (type mismatch or invalid character for the specified codepage) for row 1, column 5
Bulk load data conversion error (type mismatch or invalid character for the specified codepage) for row 2, column 5
.
.

The fix for this was to remove the trailing ',' character at the end of each line in the CSV file as shown below and then perform SSIS Bulk Insert.
0,0,35.6,-122.5,1
0,1,35.61188,-122.4438,1
0,2,35.61979,-122.4062,1
.
.

Speed
I did not observe any significant difference in the data load speed of SqlBulkCopy & SSIS Bulk Insert task. I will post performance numbers at some later time.
