The GoBack and GoForward methods on the UWP WebView (x-ms-webview in HTML, Windows.UI.Xaml.Controls.WebView in XAML, and Windows.Web.UI.Interop.WebViewControl in Win32) act the same as the Back
and Forward buttons in the Edge browser. They don't necessarily change the top level document of the WebView. If inside the webview an iframe navigates then that navigation will be recorded in
the forward/back history and the GoBack / GoForward call may result in navigating that iframe. This makes sense as an end user using the Edge browser since if I click a link to navigate one place
and then hit Back I expect to sort of undo that most recent navigation regardless of if that navigation happened in an iframe or the top level document.
If that doesn't make sense for your application and you want to navigate forward or back ignoring iframe navigates, unfortunately there's no perfect workaround.
One workaround could be to try calling GoBack and then checking if a FrameNavigationStarting event fires or a NavigationStarting event fires. If a frame navigates then try calling GoBack again.
There could be async races in this case since other navigates could come in and send you the wrong signal and interrupt your multi step GoBack operation.
You could also try keeping track of all top level document navigations and manually navigate back to the URIs you care about. However, GoBack and GoForward also restore some amount of user state
(form fills etc) in addition to navigating. Manually calling navigate will not give this same behavior.

a short, monotonous buzz tone (help·info), repeating at a rate of approximately 25 tones per minute, for 24 hours per day. The station has been observed since around 1982.[1] In rare occasions, the
buzzer signal is interrupted and a voice transmission in Russian takes place. Only four such events have been noted. There is much speculation; however, the actual purpose of this station remains
unknown." Inspiration for Lost?

Irritatingly out of line with what their commercials say, in my area Comcast, under the covers of the national
broadcast digital switch, is sneaking in their own switch to digital, moving channels above 30 to their own digital format. Previously, I had Windows 7 Media Center running on a PC with a Hauppauge PVR500 which can decode two television signals at once setup to record shows I like. The XBox 360 works
great as a Media Center client letting me easily watch the recorded shows over my home network on my normal TV.
Unfortunately with Comcast's change, now one needs a cable box or a Comcast digital to analog converter in order to view their signal, but Comcast is offering up to two free converters for those
who'd like them. The second of my two free converters I hooked up to the Media Center PC and I got the IR Blaster that came with my Hauppauge out of the garage. I plugged in the USB IR Blaster to
my PC, connected one of the IR transmitters to the 1st port on the IR Blaster, and sat the IR transmitter next to the converter's IR receiver. I went through the Media Center TV setup again and
happily it was able to figure out how to correctly change the channel on the converter. So I can record now, however:
- I can only record one thing at a time now
- Changing the channel is slow taking many seconds (no flipping through channels for me)
- The Hauppauge card can't know if the channel change worked. So if it tries to change to HBO (I get it for free with one of the Comcast packages) which is encrypted and the converted won't show,
the channel doesn't change but the PC doesn't know it and ends up recording some other channel.
To fix (3) I need to manually go through and remove channels I don't have from the Media Center. To fix (1) I may be able to get a second IR transmitter, a third digital converter, hook it up to
one of the other inputs on my Hauppauge, and go back through the Media Center TV setup. There's no fix for (2) but that's not so bad. All in all, its just generally frustrating that they're breaking
my setup with no obvious benefit.

More ideas stolen from me in the same vein as my stolen OpenID thoughts.
Fast
Pedestrian Crossing on Four Way Stops. In college I didn't have a car and every weekend I had weekly poker with friends who lived nearby so I would end up waiting to cross from one corner of a
traffic lit four way stop to the opposite corner. Waiting there in the cold gave me plenty of time to consider the fastest method of getting to the opposite corner of a four-way stop. My plan was
to hit the pedestrian crossing button for both directions and travel on the first one available. This only seems like a bad choice if the pedestrian crossing signal travels clockwise or counter
clockwise around the four way stop. In those two cases its better to take the later of the two pedestrian signal crossings, but I have yet to see those two patterns on a real life traffic stop. I
decided recently to see if my plan was actually sound and looked up info on traffic signals. But the info
didn't say much other than "its complicated" and "it depends" (I'm paraphrasing). Then I found some guy's analysis of this problem. So I'm done with this and I'll continue pressing both
buttons and crossing on the first pedestrian signal. Incidentally on one such night when I was waiting to cross this intersection I heard a loud multi-click sound and realized that the woman in the
SUV waiting to cross the intersection next to me had just locked her doors. I guess my thinking-about-crossing-the-street face is intimidating.
Windows Searching
Windows Media Center Recorded TV's Closed Captions. An Ars-Technica article on
a fancy DVR described one of the DVRs features: full text search over the subtitles of the recorded TV shows. I thought implementing this for Windows Media Center recorded TV shows and Windows
Search would be an interesting project to learn about video files, and extending Windows Search. As it turns out though some guy, Stephen Toub implemented Windows Search over MCE closed captions already. Stephen Toub's article is very long and describes some
other very interesting related projects including 'summarizing video files' which you may want to read.

coming and sometimes from credible sources. After the article I saw tonight I thought I should go back and put together the various articles I've read on this topic. Bees may be disappearing due to
pesticides,
new organic pathogens,
genetically modified crops,
mobile
phones, or
climate change. Apparently,
the US hasn't been keeping accurate counts of its bees so we
don't know the extent of the situation. There's an
interview with Maryann Frazier, M.S., of the Dept. of Etymology at
Penn State and a
congressional hearing on the matter.
I know this is all very serious and could signal the end of our ecosystem as we know it, but I can't help throwing in the following links as well. The bees could be
hiding in this Florida couple's kitchen. Or perhaps they're laying low while being
trained by the government to fight terrorism. Or
they're hiding in extra dimensions that we mere humans can't perceive (I'm fairly certain that's what this
article is suggesting. Really. Read it. Seriously. Its awesome.)
