Security for the Paranoid

"I use very long passwords for everything, even with the lamest accounts I have.
I require my kids to use at least 14 character passwords on our home network and I'm considering issuing them smart cards.
I don't just throw out shredded documents; I spread the shredded bits into my garden to use as mulch.
I keep my PC's turned around so I can tell if anyone has installed a hardware keylogger.
I do my Internet browsing from a locked down VMWare box that has no rights on my network. It takes five passwords to boot up my laptop and check my e-mail. One of those passwords is over 50 characters long."

Vive les Blogues!

According to statistics from the National Institute for Technology and Liberal Education, French is now the most common language in the blogosphere after English.
...
And this is without counting French blogging in English.. Shame on me.
...
Spurred by a culture of popular expression and debate that can be traced back to France's 17th-century salons, the French are embracing weblogs with a greater zeal than anyone...

Google Personalizes the Web

Say goodbye to bookmarks: Google has rolled out a seriously cool search history feature that automatically keeps track of all of your web searches and every page that you view from search results. (see Google labs)

A feature that will change my life or a big personal information trap?

I'll give it a try but my expectations are high. If it don't change my life, it will be disabled.

Bell to offer Bell VoIP service

Bell Canada starts offering VoIP service in three Quebec cities (Quebec City, Trois-Rivières and Sherbrooke), a move that rivals contest in front of CRTC (Radio-television regulation company that has no influence on Internet affairs..).

Funny enough, Bell had a publicity campain to make people believe that VoIP telephone services over cable are not reliable...

Speeding up Excel under C#

Problem: my web application had to output a huge Excel file on demand. It was simply a snapshot of database tables written on multiple WorkSheet.. The first version I wrote requires almost 30 seconds to dump the entire database. The problem was the call to a COM operation for each cell:

foreach(DataRow row in dataSet.Rows) {
foreach(DataColumn col in dataSet.Columns) {

secondWorkSheet.Cells[rowIndex,colIndex]=row[col.ColumnName].ToString();
...

}
}

Solution: An easy improvement (found here) consists in writing an entire range from a C# array. In my case, the speed dropped to 1-2 seconds!!

Excel.Range range = secondWorkSheet.get_Range(first, last);
Object[,] array = new Object[numRows,numCols];

foreach(DataRow row in dataSet.Rows)
{
colIndex=0; rowIndex=0;
foreach(DataColumn col in data2.Columns)
{
array[rowIndex,colIndex] = row[col.ColumnName].ToString();
colIndex++;
}
rowIndex++;
}

range.set_Value(Missing.Value, array);
