Make your own Google

Tuesday, October 24th, 2006

Google Co-op allows you to create your own search engine. You specify a list of sites and are given a home-page which lets you use Google to search just that list or the whole web but with an emphasis on those sites.

This is really useful for specialists or groups of people who have a set of quality sources on a given topic. e.g. Ruby on Rails developers or horticulturalist. Google Co-op lets just one person or a group of invited people to contribute to the list.

I think it is even more useful as a personal search engine. Here I have created a search list that searches just my resources on the web. It includes my Flickr photos, my del.icio.us and Blinklist links and my blog. Other people can use it but it is more useful to me as a way to pull out past things I have written about, photographed or linked to.

Rollyo does much this but I found their interface a bit complicated and it wasn’t using the great Google search engine.

SlideShare your presentations

Wednesday, October 4th, 2006

Awhile back I did a talk on Ajax and wanted to share the presentation with the world. It was pretty low-tech, a link to a downloadable PowerPoint file. You had to have PowerPoint or its viewer and you couldn’t preview the slides.

I also recently attended RailsConf Europe 2006 and collected some of the presentations together. Once again low-tech links to slide files. No previews and with the wide audience I’ll bet many didn’t have PowerPoint.

Not long ago we had the same problem with sharing video. Different formats, no easy way to preview, downloading links and files and what not. Then YouTube came along and suddenly all you needed was Flash and you could upload and view thousands of videos. No codec hassles, what a pleasure.

SlideShare does that but for presentation files. Upload a PowerPoint file and anyone with Flash can view it. That rocks.

TechCrunch gave a good overview and listed a few problems. I’d like to add that SlideShare needs to support more presentation formats (and telling Keynote users to save as PPT is probably not the best idea though it is practical for now.) And not just the standard presentation formats but PDF and HTML too. Loads of the RubyConf speakers distributed their slides as PDF. SlideShare should support that.

Full screen viewing would be good too. I am not sure how they do the conversion but Flash supports vector fine so scaling to any resolution isn’t a problem. You can go full-screen as the comment below suggests and it works well. Also I just noticed two clever features; for each slide the public can comment. So it isn’t just a general comment per presentation. The other feature is that the text of each slide is extracted and shown below the presentation. Very clever and I imagine will make search engines happy.

It is in private beta at the moment but I got an invite pretty easily. All in all though SlideShare is a fantastic idea and works pretty well. Give it a go.

Google Reader redux

Friday, September 29th, 2006

Google’s feed reader has undergone a radical redesign. So radical it now resembles every other feed reader out there. The previous incarnation was loved by a few and disliked by many. It was an interesting experiment but was not succesful, unlike the GMail interface.

At first glance it is a Bloglines copy; 2 panes showing feeds on one side and items on the other. You click a feed or folder and all the unread items are displayed in a river of news down the right. You can organise by folder, you can star items, email them, share (more on that later) and add tags. Nothing exceptional and certainly not stunning (I am worried when people call a minor step forward as “stunning.”)

Google Reader redux

There are some good features though and I imagine Google Reader will follow GMail in being an incrementally improving product.

The share feature lets you mark an item as shared and this is then added to a publically available web-page which has its own Atom feed. This is useful as it lets you broadcast to the world any items you find interesting.

It is limited though in that you can’t branch the sharing out to different groups. Thankfully the tagging feature comes into play here. You can add tags to any item and then make that tag public. You can then share the public tag link with other Google Reader users and they can subscribe to it. You could tag items to target specific groups of friends and co-workers. This is a very useful feature though I’d prefer if it displayed as the sharing feature does as currently the public tags require you to be using the Google Reader.

Another novel feature is that, unlike Bloglines where clicking a feed or folder marks all unread items in it as read, Google Reader will track your scrolling and only mark as read the items you have scrolled past. This makes it very easy to start reading a list of unread items, close the reader and then come back to where you last where.

Starring like in GMail works well, useful for coming back to items later to read. The feed management interface is a bit clunky but works well enough for now.

One thing I have noticed is that Bloglines seems to be faster both in using and in noticing updates in feeds. Hopefully Google Reader catches up in those two regards.

All in all it is Bloglines plus some useful features and mechanisms. I like it but feel it is hardly ground breaking and that there is so much more potential in aggregator applications. I will be swapping to Google Reader not because it is stunning but because it is mildly better.
