Epilogue to the computer video problem I was having: The new hdmi cable predictably did nothing. So I was going to install the other video adapter I had. But the huge heat sink it's got wouldn't fit in the new box, which is a slim-line case. Sigh. So I found a good price on another adapter that had a smaller heat sink and came with a bracket to fit in a slim case. Awesome. That showed up yesterday...and the bracket for the slim case mounts 180 degrees from the way I need it to mount to fit in this case

So I just installed it without the bracket. Not ideal, but it works. And the problem I was having is solved. Hooray.
Meanwhile...
Twitter is doing weird sh*t to me.
Every 4th or 5th time I load the home page, there's a bunch of random crap in the timeline from people I don't follow (most often it seems to be a bunch of Spanish-language soccer related stuff, but I've also seen random celeb account sh*t like snooki, KimKardashian, JustiBieber show up). They are not retweets from people I am following, they go away if I refresh the page, and I don't see them from my mobile app, just the home page from a web browser (both firefox and IE).
This is a screenshot, the last few tweets you can see on the bottom are supposed to be there, everything above that is crap, and went away after I refreshed the page.
Really annoying.
