Network notary system thwarts man-in-the-middle attacks

2008 Aug 26, 10:03"A new system devised by Carnegie Mellon University researchers aims to thwart man-in-the-middle (MitM) attacks by providing a way to verify the authenticity of self-signed certificates. The system, which is called Perspectives, uses a distributed network of "notary" servers to evaluate the public key of a target destination so that its validity can be ascertained."PermalinkCommentssecurity ssl pki certificate man-in-the-middle

Tag Metadata in Feeds

2008 Aug 25, 10:13

As noted previously, my page consists of the aggregation of my various feeds and in working on that code recently it was again brought to my attention that everyone has different ways of representing tag metadata in feeds. I made up a list of how my various feed sources represent tags and list that data here so that it might help others in the future.

Tag markup from various sources
Source Feed Type Tag Markup Scheme One Tag Per Element Tag Scheme URI Human / Machine Names Example Markup

Kids in the Hall Live in Seattle

2008 May 17, 7:58

Sarah and I saw the Kids in the Hall "Live As We'll Ever Be" Tour in the WaMu theater in Seattle this past Thursday. I'd only ever seen their television show so it was cool to see them live. I thought that them being in a live format on stage would make the show significantly different, but other than having a bad seat and not being able to see very well, and the Kids sometimes ad-libbing or breaking character, it was like watching their show. It consisted of mostly new material with some returning characters like the Chicken Lady, Buddy Cole, the head crusher, etc. Their Facebook page has two videos that they played during the show.

I've been using the best Kids in the Hall fansite with an archive of searchable transcripts since high school. But now days what with all the new fangled video websites I can link right to some of my favorite sketches from the show. Like the Inexperienced Cannibal.


And the meta-sketch The Raise.

Search and Archive of Dave's Things

2008 Apr 7, 10:31

Photo of crates in a warehouse. Licensed under creative commons by Don Jones.I now have search and an archive available for my site. I previously tried to setup crappy search by cheating using Yahoo Pipes and now instead I have a slightly less crappy search that works over all of the content that I've produced on my blog, uploaded to flickr or youtube, or added to delicious.

You can now read my first LiveJournal blog post or, for probably much more entertainment value, view all the photos and videos of Cadbury by searching for 'bunny'.

The search is only slightly less lame because although it searches over all my content, I still implemented it myself rather than getting a professional package. Also, the feed supports the same search and archive as my homepage so you can subscribe to a feed of Cadbury if you're so inclined and just skip all this other boring stuff. My homepage and feed implement the OpenSearch response elements and I've got an OpenSearch search provider (source) as well.

Gmail integration with Internet Explorer 8

2008 Apr 3, 9:00

Internet Explorer LogoGmail Logo licensed under CC by Victor de la FuenteWith the new features of IE8 there's several easy ways to integrate Gmail, Google's web mail service, for mail composition, searching, and monitoring that I enjoy using.

Composition
I made a Send via Gmail activity that allows you to select some text, a document, or link and via the activity menu open a new tab to compose a new message with the selection. Go to my activity page and click "Send via Gmail" (source) to install it. I found info on the gmail composition URL in the comments of this gmail howto article and used that in the activity. I talked about activities previously.
Search
I've made a search provider that searches your gmail account. See my search provider page and select 'Gmail' (source) to install the Gmail search provider. Search providers aren't new to IE8 but this fits in with Gmail integration in IE. Again in the comments of another howto I found information on a Gmail search URL.
Monitor
New to IE8 is authenticated feed support and favorites bar monitoring which combined with the Gmail inbox feed means you can see when you get new mail in your favorites bar in IE. To do this, navigate to the feed https://mail.google.com/mail/feed/atom, click 'Subscribe to this feed', then click on the Add button in the upper left (the star with plus icon) and select 'Monitor on Favorites Bar' to add this as a monitored item in the favorites bar. Next, right click on the new item in your favorites bar, open the properties dialog, and enter your Gmail username and password into the new username and password fields. Now when you get new mail the Gmail feed item will shine and bold and you'll be able to get to new messages in the dropdown. I described monitored feed items previously.

Juanita Beach Visit and Map

2008 Mar 7, 3:26

Don't Feed the Ducks SignTwo weekends ago it was actually sunny and kind of warm so Sarah and I went down to Spud Fish and Chips and Juanita Beach Park. We ate fish and chips on the dock. I took a few pictures and this time actually put some geographical information on Flickr so now I've got a map of my tiny fish and chips journey. On the map click on the floating marks to view the associated photos.

Flickr provides access to the geo data associated with your photos via GeoRSS feeds. And Google Maps displays GeoRSS feed content on their maps allowing you even to edit the data but doesn't appear to let you easily export the GeoRSS. Live Maps does the inverse, allowing you to create and export GeoRSS data but not import it. I'd like both please. Oh well.

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.
