In documenting the various Project54 research efforts I upload many pictures to my Flickr account and many videos to my YouTube account. However, for the past few weeks I’ve had problems connecting to Flickr and to YouTube. Basically, I’d attempt to upload files and the operation would fail. Small pictures would suffer the same fate as large videos - they wouldn’t make it to the destination.

I mentioned this problem to Frank Hludik and he found the problem: it was the TCP auto-tuning that my Vista machine performed. Here is a longer article describing the problem and the solution, and here is a shorter one. The bottom line for me: I disabled TCP auto-tuning and now I can upload pictures and videos. Thanks Frank!
