Features of image type input tags in HTML

2011 Nov 21, 11:00

A bug came up the other day involving markup containing <input type="image" src="http://example.com/.... I knew that "image" was a valid input type but it wasn't until that moment that I realized I didn't know what it did. Looking it up I found that it displays the specified image and when the user clicks on the image, the form is submitted with an additional two name value pairs: the x and y positions of the point at which the user clicked the image.

Take for example the following HTML:

<form action="http://example.com/">
<input type="image" name="foo" src="http://deletethis.net/dave/images/davebefore.jpg">
</form>
If the user clicks on the image, the browser will submit the form with a URI like the following:http://example.com/?foo.x=145&foo.y=124.

This seemed like an incredibly specific feature to be built directly into the language when this could instead be done with javascript. I looked a bit further and saw that its been in HTML since at least HTML2, which of course makes much more sense. Javascript barely existed at that point and sending off the user's click location in a form may have been the only way to do something interesting with that action.

Replacing Delicious with Google Reader

2011 Nov 17, 11:00

I had previously replaced my use of Delicious with Google Reader. Delicious had a number of issues during their switch over from Yahoo to the new owners and I was eventually fed up enough to remove it from daily use. I used Delicious to do the following things:

  • Create a list of things to read later
  • Save things to read again in the future
  • Search through things I read and enjoyed (esp via tags)
  • Annotate and share things on my blog
I realized that since I did most of my web browsing in Google Reader now anyway I may as well make use of its features. I star things to note I want to read it later or save to read again later. I can annotate with notes in Google Reader and I can share items to my web site by way of the shared items feed. Additionally for when I'm not in Google Reader there's a bookmarklet to add an arbitrary web site as a shared item in Google Reader.

Of course I wrote this and switched over about 1 week before Google removed the sharing feature from Google Reader. I'm irritated but in practice it forced me to find a different option which has worked out mostly better. New blog post coming soon about that...

The Future of Data Tags: Bokodes | Brain Pickings

2009 Aug 5, 7:57"Ten times smaller than barcodes, Bokodes’ low-cost optical design can be read from as far as 4 meters away, much farther than barcodes, by taking an out-of-focus photo with any off-the-shelf camera." Love for stuff like this to catch on, however compared to QR codes, these are much more difficult to produce than barcodes in that you can't just print them out and they require changes to the photography technique (must be out of focus) rather than just analyzing any photograph of a barcode. They seem to be solving slightly different problems.

Dave's Blog Entries Last Year

2009 Jul 19, 4:00

Inspired by one of Penn's (of Penn & Teller) articles in which he mentions he has his computer tell him what he wrote in his journal that day the previous year, I've wanted to implement a similar thing with my blog. Now that, as I mentioned previously, I've updated my blog such that its much easier to implement search and such, I've added date range filtering to my site's search. So now I can easily see what on Delicious and my blog I was doing last year.

I've also otherwise updated search on this site. You can now quote terms to match an entire string, stick 'tag:' in front of a term to only match that term against tags as opposed to the title and body of the entry as well, and you can stick '-' in front of a term to indicate that it must not be found in the entry.

Outline View Internet Explorer Extension

2009 Mar 23, 8:13

I've made another extension for IE8, Outline View, which gives you a side bar in IE that displays an outline of the current page and lets you make intrapage bookmarks.

The outline is generated based on the heading tags in the document (e.g. h1, h2, etc), kind of like what W3C's Semantic data extractor tool displays for an outline. So if the page doesn't use heading tags the way the HTML spec intended or just sticks img tags in them, then the outline doesn't look so hot. On a page that does use headings as intended though it looks really good. For instance a section from the HTML 4 spec shows up quite nicely and I find its actually useful to be able to jump around to the different sections. Actually, I've been surprised going to various blogs how well the outline view is actually working -- I thought a lot more webdevs would be abusing their heading tags.

I've also added intrapage bookmarks. When you make a text selection and clear it, that selected text is added as a temporary intrapage bookmark which shows up in the correct place in the outline. You can navigate to the bookmark or right click to make it permanent. Right now I'm storing the permanent intrapage bookmarks in IE8's new per-domain DOM storage because I wanted to avoid writing code to synchronize a cross process store of bookmarks, it allowed me to play with the DOM storage a bit, and the bookmarks will get cleared appropriately when the user clears their history via the control panel.

QuickBase Formula Pretty Printer and Syntax Highlighter

2008 Oct 5, 9:17

Sarah asked me if I knew of a syntax highlighter for the QuickBase formula language which she uses at work. I couldn't find one but thought it might be fun to make a QuickBase Formula syntax highlighter based on the QuickBase help's description of the formula syntax. Thankfully the language is relatively simple since my skills with ANTLR, the parser generator, are rusty now and I've only used it previously for personal projects (like Javaish, the ridiculous Java based shell idea I had).

With the help of some great ANTLR examples and an ANTLR cheat sheet I was able to come up with the grammar that parses the QuickBase Formula syntax and prints out the same formula marked up with HTML SPAN tags and various CSS classes. ANTLR produces the parser in Java which I wrapped up in an applet, put in a jar, and embedded in an HTML page. The script in that page runs user input through the applet's parser and sticks the output at the bottom of the page with appropriate CSS rules to highlight and print the formula in a pretty fashion.

Schmap Licenses my Photos

2008 Feb 18, 1:34

Hotel Diva Computer RoomI got a FlickrMail from Emma J. Williams a bit ago saying that they wanted to use two of my photos in their Schmap San Francisco Guide online travel guide. So now you can see two of my vacation photos on the Westfield San Francisco Shopping Center Schmap page and the Hotel Diva Schmap page.

Westfield San Francisco EscalatorI think its wonderful that digital cameras are at the point where I really don't have to know much about their workings to produce a photo that's reasonable looking. And its thanks to Flickr and searchable tags that Schmap could find my photos. Since my photos on Flickr are all licensed under a Creative Commons license named Attribution-Noncommercial-No Derivative Works 2.0 Generic which only applies to non-commercial uses, Schmap, which is advertisement supported, kindly asked me if they could use my photos. I agreed to their license which was human readable and included wonderful stuff like I get in place attribution and the license is only applicable while Schmap makes their guide freely available online.

Previously I've only heard of folks having their flickr photos used without their permission so I'm glad to know that's not always the case. Or perhaps this is just Schmap's clever method of getting me to blog about them.

Personal Search with Yahoo Pipes

2008 Feb 3, 11:59

I've setup a minimal search page that uses a Yahoo Pipe to sort of search through my content. I say sort of search because I only get full text search over my recent item feeds and otherwise I just search over my tags.

To get real search I'm going to have to keep an archive of all my content on my own website. This is a pain but on the other hand it will let me easily backup my content or display old items on my page. Why didn't I just use a prebuilt solution?
