Starting up the Walker Blogs has been a bit of a challenge. The WordPress application was relatively fast to set up and design for, but we have been off to a slow start adding departments to blogs.walkerart.org. If you visit that page you can see it is just New Media and Education holding down the blog fort. The Walker certainly has a lot more going on than those two departments so what is going on?

In all probability the slow adoption of blogs has been related to the time crunch surrounding our opening, but I think it also has something to do with our incomplete explanation of what blogs are and how they can be put to good use. To that end I did some research online for people who already answered these questions better than I could. I found a lot of resources addressing this issue for educators and non-profits in general but nothing specifically targeting multidisciplinary art centers like ours, so I took some time to write answers to common questions I get asked.

First of all I’ve been asked “ What is a Blog?” a few times so lets get that out of the way.

It’s a series of writings about topics currently of interest to you or your audience sorted in chronological order (newest first oldest last). Written entries are referred to as posts and are published by the author without the assistance of any New Media staff. Each post includes a tool that allows the audience (any one on the internet) to make comments about the post.

There is a good article on TechSoup called An Introduction to Weblogs that goes through this in more detail.

A couple of times people have asked “ Why would I want to blog? How could it help me?” or they boil those two questions down to something simpler like “ I don’t really have time to blog right now, maybe later”.

Extended RSS

We’ve talked for a while about adding RSS feeds all over the Walker website, not just for blogs and our calendar, but also for things like the Channel, and our programming department sites.

We’ve talked for a while about adding RSS feeds all over the Walker website, not just for blogs and our calendar, but also for things like the Channel, and our programming department sites. As such, we figured it best to write a genearal script to create all of the RSS feeds so we wouldn’t have to rewrite them all of the time.

Nate looked into this and found a few other things in the process. Basically we were using the bare minimum of RSS 2.0, and as such were missing a few things to extend our RSS feed to make it better. Chief among these were PubDate and URI fields. These fields are not required, but most RSS readers use them, and thus they have been added to our feeds. Also new is the addition of HTML tags in our body copy. As such, now you should be able to see bolded and italicised words, as well as images. This helps out a lot with our calendar feed.

I also noticed, specifically on our calendar, that we weren’t adding a header link to our RSS feeds on our web sites. Safari and Firefox can use these header links to display if an RSS feed is available without a user having to put a direct link on their page (both browsers also allow you to subscribe to an RSS feed from the browser this way). You can see this feature on this post if you’re using either of these browsers. We’ve since added this to the calendar as well.

We’re also introducing our new Walker Channel RSS feed. There was the talk earlier about doing Vodcasting on the Channel site, however, we felt that a simple RSS feed with a link to the video in question was a better fit. It still gives people the opportunity to watch and be alerted to new content in the Channel, but uses your regular news reader to do so. Those interested in watching Walker content will want to check it out.

Zoomify Analysis

As part of our continuing maintenance of Arts ConnectEd we are looking for a replacement of our image viewer in the art collector tool.

Our requirements are fairly straight forward. We need an image viewer than can magnify images move around them then save the zoom level and coordinates in some way preferably in the URL for easy bookmarking.

The best way to do this I would assume is to have server side program take a large image and slice it up into managable files and save a low res and hi-res version of each slice numbered sequentially. Then the front end would either be made in Flash or DHTML to load and display the images to the client (the browser).

This is essentially the model we followed when developing the Radio Re-Volt website, which was made in Flash. A similar model was used by Google in their Maps tool, with a DHTML interface.

A commercial product called Zoomify has come to our attention. Zoomify is a Flash MX 2004 product that reads image slices. It has a wide userbase so far including other cultural institutions, commercial fashion designers, mapping and for satelite imagery services.

I found a few examples of people using the product that were notable.

A.P.C.: Minimal controls and dragging the image.

The Getty: Used on several works in most exhibitions including Rembrandt’s Late Religious Portraits and Illuminating the Renaissance

Philadelphia Museum of Art: Used in special exhibitions such as Manet and the Sea where it also provides a soundtrack commentary for the image.

The software comes in a few flavors.

Zoomify EZ

This is the free version. It includes the viewer SWF an HTML template and a desktop application for slicing a large image. You drag an image onto the application and it generates a folder with images slices (three levels deep) and an XML file to describe the set.

Podcasting: Next Steps

Recently, New Media Initiatives met to discuss Podcasting, what we wanted to do with it, and even if the idea made sense. Several things came out of this discussion.

Recently, New Media Initiatives met to discuss Podcasting, what we wanted to do with it, and even if the idea made sense. Several things came out of this discussion. First was that the main thing we want to do is simply allow users to listen to relavent info from artists, just like they can do with Art on Call, but instead use their iPods or another MP3 player. This could be as simple as someone selecting which artists they’re interested in from a list, or perhaps a preset “tour”, and downloading the appropriate MP3s to put on their iPods. Then when a patron is in the galleries, they simply bring up the artist they wish to listen to and hit play while standing in front of the work.

Would podcasting be the way to do this? Well, it turns out yes and no. In my last post I mentioned that podcasting is time sensitive, but thanks to an email and subsiquent meeting with Garrick Van Buren, who does quite a few of his own podcasts, I came to realize that this isn’t neccesarily true. I kept getting stuck in the notion that if the idea of podcasting was to broadcast new “radio shows”, then letting someone randomly select artist interviews to listen to wasn’t the same as a podcast. But really all a podcast is is a list of MP3s one can download, they don’t neccesarily have to be in order, or flow together, or be time sensitive. When thought of like this it makes more sense. We can publish our entire list of available artist stops online in our podcast RSS, and people can then select which works interest them, and only download those specific MP3s. So the idea still works.

But we don’t want to limit the ability to recieve these MP3s to podcasts or podcast software. So in addition to building a podcast RSS feed for people to use, we’re going to build an index list online in the Art on Call website, for people to check off which work MP3s they want to download and then let them take those files and put it into their iPod from the web itself. This gives people without a podcast reader, or iTunes, or even an iPod, a way to get the same audio from our website. In reality, we’re just distributing MP3s, so why not give people some different options on how to recieve them?

The other thing Garrick and I talked about was user tours. The idea is you could comment on an artwork after you hear about it when you dial Art on Call. It would save this as a voicemail, which automatically archives it to MP3, and we could pick the best comments to create user tours. This would allow people to choose multiple “versions” of the same tour. You could pick from the artists tour, the Teen remix, or the user tour of the same show, each having a different perspective on the work. Thankfully this has already been in planning from the beginning as an option to potentially pursue, so the groundwork is there, it’s just a matter of getting the time, support, research, etc to actually move forward and do it.

So, things are starting to solidify here, and we have a path to start down. First will be the online downloads from the Art on Call website, since we can start this right away, and it will be compatible with any MP3 software or player out there. After this we will look into podcasting this same info for people who prefer that distribution method. It looks like the new version of iTunes will be out by early July, so we should be able to do tests with that shortly as well.

Lastly, look for more RSS newsfeeds in general all over our website. We plan on having newsfeeds for each of the programming department sites (Performing Arts, Visual Arts, Film/Video) which includes blogs, events, articles, etc, and we also are going to do a newsfeed on the Channel, so people can stay up to date on what we are webcasting, and what has been archived to watch and enjoy. So look for that soon as well.

Podcasting: The Beginning

One of the things we’ve thought about with the Art On Call project is extending it beyond just cell phone use, especially for the artwork stops. Cell phones are great, most people have them, but not everyone wants to be on the phone and using thier minutes in the galleries. How else can we distribute [...]

One of the things we’ve thought about with the Art On Call project is extending it beyond just cell phone use, especially for the artwork stops. Cell phones are great, most people have them, but not everyone wants to be on the phone and using thier minutes in the galleries. How else can we distribute this information? Enter podcasting.

Podcasting isn’t new, it’s been around for a bit and is moving ever more mainstream each day (in fact the new version of iTunes due out within 60 days will have podcasting built into it). You can think of Podcasting as blogging with audio. You set up an RSS feed, and embed links to MP3 files in it. You subscribe to these feeds just like you do to a blog, and when your news (podcast) reader checks for updates, it downloads any new podcasts it finds to your computer for you to listen to.

A lot of news organizations are starting to do this. It also allows anyone with a microphone and a computer the ability to comment and share their thoughts online. It’s like Tivo (time shifted) and Wayne’s World (average user created) radio. Since the files we use in Art On Call are simply MP3 streams, we can basically podcast tours online for users to download to thier iPods and bring to the Walker and listen to when standing in front of artwork.

One thing we’re also looking into is adding a docking station to our lobby Kiosks, that let people who bring their iPods with them to sync up and download the latest audio tour to it. There’s even talk about potentially doing a “remix” podcast and letting our Teen Arts Council comment are various artwork and using their interpretations of art as a different perspective for users to contemplate when touring the galleries. There are a lot of options here.

There are also a lot of questions. Today some iPods arrived at the Walker for us to start testing this out. I’ve already made a sample podcast on our dev server to test as well. There seem to be several technical limitations to the current way podcasting is done, given that it’s time sensitive and one show at a time, whereas our idea involves the potential for an entire playlist of audio, with perhaps multiple podcasts. There’s still a few things to work out and test, but the results should be pretty interesting, and will give visitors yet another way to experience our artwork. Updates on progress are sure to come soon.

Screen Saver (Tiger only)

One of the side benefits of making Quatz Composer files is that you can use them as screen savers in Tiger (OS X 10.4) just by putting them in the right folder. The folder path should be: Macintosh HD > Library > Screen Savers or Macintosh HD > Users > “Your User Name” > Library [...]

or

Macintosh HD > Users > “Your User Name” > Library > Screen Savers

I put a few of my first tests online. They are rough but kind of fun and they all run off our RSS feed. Feel free to use them as screen savers or open up the source either way let me know what you think.

Quartz Compser = Dynamic Signage?

I’ve been testing out a new software that shipped with Apple’s 10.4 Developers tools called Quartz Composer.

I’ve been testing out a new software that shipped with Apple’s 10.4 Developers tools called Quartz Composer. It is generally the exact type of software I was looking for to power the dynamic signage projects. It can import live data and display it in a motion graphics environment then either animate it live or make a quicktime movie for burning on DVD. There is logic before the rendering so we can adjust our animation depending on length of words or number of events. The interface is very interesting, it’s a visual editor with different “patches” connected with “cords” that you string together for more complex functions. There is simple javascript control but it seems quite slow in my initial experiements. Any one familiar with the older Pixel Shox software will notice that Quartz Composer is very similar. In fact the primary (only?) developer for Pixel Shox was brought in at Apple as the Quartz Composer Architect.

Apple has a great mailing list and Q+A page that have been extremely helpful. The user community seems to be very excited about the technology and they put together some good resources at Quartz Comps and Quatz Wiki.

This is very exciting news unfortunately there are some other considerations. Quartz obviously will only run on Macs. That means our elevator signs could be switched from a DVD player to a Mac with a minimal investment but our WatchOut Sign system all runs and relatively high end PCs and could not be transitioned without a significant expense.

That means our way forward for the large Hennepin Projection would be to use Quartz to render movies and send those quicktime movies over to the Watchout computers to play. That could work fine but I am in the middle of diagnosing some problems where the Watchout software doesn’t always recognize changed content.

There will obviously have to be some more discussion on our part and more testing before we will have a plan to fully drive our signage system from our database.

Note: I learned about Quartz Composer from Justin of the Revolutionary Party whose Workshop at the Walker is going to be great and deserves a plug. Thanks for the tip.

Recently the New Media department at the Walker completed a cubicle shuffle. In the process I stumbled across this great lost peice of technology that fulfills no useful function but still I haven’t been able to part with. It is the Radio LAN.

A precursor to WIFI the Radio LAN extended a 10Base T Network ao the FM radio waves by means of this “backbone” and transmitter (a 50mW transmitter). The instruction manual claims to have had a range of 150-200 feet.

Radio LAN

On the other end of the transmission you need one of these cards. A standard PCMCIA card that has some sort of gigantic plastic thing on it to receive the signal. I have it plugged into my 15″ powerbook just so you can get an idea of scale.

Radio LAN card

The copyright from the instruction book is from 1998 so it seems way ahead of it’s time. Nice to see the Radio LAN company is still in business but it looks like their products have changed into more long range wireless solutions.

Now that I have successfully documented and shared this great step in wireless history I think it’s finally time to get rid of it.
