Measuring Download Speed from Linux Command Line

I recently needed to test the network speed of the ISP from my Ubuntu 10.04 LTS server. I was trying to think of a better way to test it than going out to a Linux Distro's web site and downloading an ISO from them. I stumbled across this post on StackOverflow that had a URL to a speedtest.net test file and my speedtest scripts were born. I created two scripts; one utilizing wget and one utilizing curl. A lot of machines don’t come with curl by default, but it has a lot more output than wget does while downloading.

 

What Do They Do?

The scripts utilize wget or curl to download the speedtest.net 500M test file and you can view the speed results in real time. This is an entirely unscientific method of testing your speed, but much better than say, going to Ubuntu and downloading their latest ISO via wget. Finally, the output is set to go to /dev/null, which means it simply throws away everything it downloads (no cleanup).

 

The Code

Changing Created By or Author Property in SharePoint 2007

After a frustrating experience, I’d like to share the ‘secret’ of updating the Created By and/or Author SPListItem system property. I was trying set the Created By and/or Author SPListIem system property but found that the changes didn’t take and my object’s values were reset after calling SPListItem.Update();

The Wrong Way

If you’re like me, you probably assumed something similar to this would work just fine:

Not so fast my friend! If you trace/quickwatch your variables you’ll notice that your Created By property is reset after the update. Why? Because you didn’t set all the necessary properties. Oh, you didn’t know you had to set other properties at the same time to get Created By or Author to stick? Neither did I, until now…

The Right Way

Maybe not the correct way, but the way I got it to work:

That’s right, to successfully save the Created By property you must also set the Modified By and Modified properties AND call SPListItem.UpdateOverwriteVersion() to get the Created By property to actually save your new value. Hopefully you find this post sooner than I found my answer.
