Internet Explorer 8 Beta 1 Released with Activities

2008 Mar 5, 11:36

Internet Explorer 8 Beta 1 is available now. I can finally talk about some of the stuff I've been working on for the past year or so: activities. Activities let you select a document, some text on a document, or a link to a document and run that selection through a web service. For example, you could select a word on a webpage and look it up in Wikipedia, select an address and map it on Yahoo Maps, select a webpage and translate it into English with Windows Live Translator, or select a link and add it to Digg.

IE8 comes installed with some activities based on Microsoft web services but there's a page you can go to to install other activities. However, that page is missing some of my favorites that I use all the time, like del.icio.us. Accordingly, I've put together a page of the activities I use. MSDN has all the info on creating Activities.

Activities are very similar to other existing features in other browsers including the ability to add context menu items to IE. There's two important differences which make activities better. Activities have a preview window that pops out when you hover over an activity, which is useful to get in place information easily provided by developers. The other is that the interface is explicit and takes after HTML FORMs and OpenSearch descriptions. Because the interface is explicitly described in XML (unlike the context menu additions described above which run arbitrary script) we have the ability to use activities in places other than on a webpage in the future. And because activity definitions are similar to HTML FORMs, if your webservice has an HTML FORM describing it you can easily create an activity.

IE7 Feed Display Update

2007 May 22, 3:22I've created an update to the IE7 feed display.

After working on my update to the XML source view I tried running my resourcelist program on other IE DLLs including ieframe. I found that one of the resources in ieframe is the XSLT used to turn an RSS feed into the IE7 feed display.

My first thought for this was that I could embed enclosures into the feed display. For instance, have controls for youtube.com videos or podcast audio files directly in the feed display. However, I found that I can't use object or embed tags that rely on ActiveX controls in the page or in frames in the feed display.

With that through I decided I could at least add support for some RSS extensions. Thanks to IE7's RSS platform which provides a normalized view of RSS feeds it was really easy to do this. I went to several popular RSS feeds and RSS feeds that I like and took a look at the source to see what extensions I might want to add support for.

For digg.com I added support for their RSS extension which includes digg count, and submitter name and icon. I added the digg count in a box on the right and tried to make it fit in stylistically. For the iTunes RSS extension I add the feed icon, feed author, and descriptions. I was surprised by how much of the podcasts content was missing from the feed view. I also added support for a few other misc things: the slash RSS extension's section and department, the feed description to the top of the feed display, and the atom author icon.

I wonder what other goodies lurk in IE's resources...feed res slashdot digg resource itunes technical browser ie rss extension

Missing Bee Roundup

2007 Apr 15, 4:06For the past several months I've seen various articles suggesting why bees are disappearing. At first I thought this was another crackpot's article that somehow made it onto digg.com. But they keep 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.)roundup personal bees nontechnical

OpenID Stolen Thoughts

2007 Mar 13, 7:57I had a few thoughts after reading about OpenID. However, after doing only a very small amount of digging I can see these aren't new thoughts.

Anonymous OpenID

Have an OpenID that anyone can use because it performs no authorization. You'd specify a URI like http://deletethis.net/anonymousopenid/yournamehere and you'd immediately get an anonymous OpenID associated with that URI. This has already been implemented by Jayant Gandhi.

Group OpenID

Have an OpenID that consists of a group of member OpenIDs. To login as the Group OpenID you need to login with any of the member OpenIDs. This is discussed more by Dmitry Shechtman on his blog.

OpenID Normalization

I find that I already have a couple of OpenIDs without even trying due to AOL giving out OpenIDs. I'd like for all of my OpenIDs to point to one canonical OpenID. It looks like this may already be possible by the OpenID specification.

I guess I'm a little late to the scene.technical stolen-thoughts openid
