GoBack/GoForward in Win10 UWP WebView

2018 Oct 23, 9:18

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.

The Strange & Curious Tale of the Last True Hermit

2014 Aug 21, 3:02

The story of Chris Knight, living in isolation in the woods of Maine for 27 years.

'Anyone who reveals what he's learned, Chris told me, is not by his definition a true hermit. Chris had come around on the idea of himself as a hermit, and eventually embraced it. When I mentioned Thoreau, who spent two years at Walden, Chris dismissed him with a single word: “dilettante.”'

'But still, I pressed on, there must have been some grand insight revealed to him in the wild…”Get enough sleep.”'

I don’t want to brag, but I’ve been telling that people all along and I didn’t have to live alone in the woods for decades.

The Doritos origin story: Repurposed garbage from Disneyland

2014 May 6, 7:16

shortformblog:

A reminder that those Doritos you love are trash:

Shortly after Disneyland opened in 1955, the founder of Frito-Lay got permission from Walt Disney to open a restaurant in Frontierland with a Mexican-ish theme. “Casa de Fritos” was, unsurprisingly, all about the Fritos. Customers got free Fritos, and Fritos were incorporated into many of the dishes. Fritos were dispensed by an animatronic vending machine that featured the terrifying “Frito Kid”asking his assistant “Klondike” to bring the bag up from a mineshaft. I guess the conceit is that Fritos were mined by Forty-Niners?

Casa de Fritos contracted their tortilla production to a company called Alex Foods. One of the salesmen from Alex Foods, making a delivery to Casa de Fritos, noticed stale tortillas in the garbage and gave the cook a little tip: fry them and sell them as chips instead of throwing them away. Casa de Fritos began making these fried, seasoned chips to enormous success, but didn’t report this new menu item to the Frito-Lay company.

Eventually Frito-Lay found out what they were doing with the chips, packaged them, and sold them by the truckload. See, dumpster diving works out sometimes!

Internet Archive lets you play one of the earliest computer games Space War! emulated in JavaScript in the browser.

This entry covers the historical context of Space War!, and instructions for working with our in-browser emulator. The system doesn’t require installed plugins (although a more powerful machine and recent browser version is suggested).

The JSMESS emulator (a conversion of the larger MESS project) also contains a real-time portrayal of the lights and switches of a Digital PDP-1, as well as links to documentation and manuals for this $800,000 (2014 dollars) minicomputer.
