Mobile Work

I've observed colleagues for years walking around with their Blackberries staying connected with their work. While I've stayed connected with work via cellphone and texting, I haven't until very recently used a smartphone to connect to work e-mail, intranet, and other work applications. I've just installed IBM Lotus Notes Traveler and I absolutely love it. I now have my work e-mail, calendar, contacts, to do lists all directly integrated seamlessly into the relevant apps and services on my iPhone. Through VPN on the iPhone, I also now have access to the company intranet and services like chat messaging.

I find it amazingly convenient to be able to quickly check my work e-mail while in line at the coffee shop and to look up where my first meeting of the day is when I'm running late and don't have time to take out and open up my notebook computer. It's an amazing time saver and uses the form factor I so love.

When I think about the convenience of having work information available like this on the device that's always in my podcast, I can imagine the utility of having it available on the somewhat larger but equally enjoyable iPad. I'm looking forward to that. There is one feature that I haven't heard anyone mention with regard to these devices that I think is critical for accessing work systems and that's fingerprint recognition. That would be so useful and Apple cool.

As always, I'd appreciate any thoughts you may have on my thoughts. By the way, I also wrote this post on my iPhone.

Social Software

We're all familiar with Social Software like Twitter, Facebook, YouTube, and blogs in the consumer space but little is often said about making this capability available in the enterprise space. I post regularly to all these systems and have done for some time but have been looking forward to a complete solution to use inside a company and behind its firewall as well. The latest release of our IBM Lotus Connections 2.5 product does just that. Listen to my interview with two of the lead designers on the project in this podcast.

Micro-blogging, Typography, Clouds, and Browsers

Joining me on this episode of UXDesignCast are Jay Trimble (Group Lead for the User Centered Technology Group, NASA Ames Research Center), Keith Instone (Information Architecture Lead, IBM CIO’s Office, IBM.com), and Eliane Tozman (User Interface Designer, IBM Media Design Studio). The panel discusses the new way of using Web 2.0 including micro-blogging behind corporate firewalls with IBM Lotus Connections 2.5, the recent typography choices make by IKEA and what impact they may have, the need to consider the total cloud user experience importantly including ISPs, the implications for designers of Google’s Chrome Frame, key principles for and examples of effective Rich Internet Application (RIA) design, and planning for World Usability Day.

Producing a Podcast - Part II

I covered everything to think about, plan, and get in order to produce a podcast in Part I a number of blog posts ago. I'll cover the actual recording and post-production in this post. The recording setup is a little different for the case of recording a podcast with only me speaking versus the case when I have one or more guests. I use Audacity for the former and Pamela for the latter. Audacity is an amazing Open Source tool for recording and editing audio. It is also free. You can get it at SourceForge.net. Pamela is a call management tool for Skype which also does an amazing job of recording one or more Skype calls. Pamela isn't free but isn't very expensive.

When I record a podcast with just myself using Audacity, I ensure that my microphone is appropriately selected as the capture device in the operating system as well as in Audacity

itself by selecting Edit, then Preferences, and selecting the Audio I/O tab. I set the recording volume level as high as possible without distorting which for me is about the seven mark on the gauge. I also watch the visualization of the recording to ensure that levels don't get to high or too low. If I make a mistake, I simply leave a pause and then start again. I look for pauses during post-production in order to remove the sections with any errors.

When I'm doing a podcast with guests, I get them all to download and register with Skype. Computer to computer Skype is free and provides the best possible recording quality. I also have Skype-out which allows me to call a land line or cell phone from my computer but I try not to use that option too often because it lowers the quality of the sound. I get the sound levels right by recording my guests and I while we talk informally before the call about planning and logistics. That type of discussion is normally important anyway but also provides the ability to adjust the Pamela and Skype recording levels. I also send out the following checklist to my podcast guests a week or more prior to the actual recording.

Please take a few minutes to go over these instructions and

guidelines well before the scheduled podcast recording.

• Install Skype if you don't already have it or if you already have it installed, make sure you have the latest version (via Help -> Latest Updates)
• Search for and connect with Skype userid "******" - that's the account that will call you on Skype just prior to the recording session
• Use a wired internet connection if possible although wireless will work if fast enough
• Make sure there are no other computers in the house (if you're recording from home) that are using the internet during the recording session
• Stop all resource intensive applications running on your computer
• Use a good quality headset and test it with the "Echo/Sound Test Service" in your Skype contacts list - (the computer mic is of insufficient quality)
• Make sure to participate on the podcast in a quiet setting with no background noise or distractions
• Please turn off all messaging clients (Sametime, MSN, etc.)
• Turn the ringer off on a phones and cell phones within earshot - even vibrate can be heard on the recording
• Keep a 3-6 inch distance of the microphone from your mouth and do not touch the microphone while we're recording
• If you need to adjust the microphone or headset during the call or cough, use the mute button on Skype, and remember to turn it off before talking
• Podcasts are quite informal so feel free to speak naturally in the way you would normally have a conversation with someone at a conference
• Make sure to sign-in to your Skype account a few minutes before the scheduled recording

I go over this checklist with my guests prior to the recording session to ensure that phones are turned off in particular.

At the conclusion of the recording, I save the session in Pamela as a wave file.

Whereas the two types of podcasts are recorded using different technologies, I edit both using Audacity with the same techniques. I first delete any discussion before and after the actual recording. I next look for any mistakes, obvious undesirable sounds (lip smacks, pops, ums and ahs), and long pauses. I select them and delete them, often first listening to them while selected to ensure I'm getting the right section.

After the editing is complete, I run the full audio through several filters by selecting All on the Edit menu and then selecting the filters from the Effects menu. I first Compress, then Normalize, and finally Amplify. This ensures that I'll have a reduced file size with consistent quality and volume of audio. I next put in the introductory music segment via the Project menu and Import Audio. I position the two audio tracks by using the Time Shift Tool. I next generate the mp3 file by selecting Export as mp3 from the File menu.

Now I've got the full mp3 file but need to add album art and text to the file so that visual identifier

for the particular podcast shows on the iPhone or iPod and that the information about the podcast shows when the screen is tapped. I mentioned the Apple products but I actually try to make my podcasts available to as wide as audience as possible and use the mp3 format for that purpose. Apple's own aac format has the advantage of being able to include multiple images throughout the podcast but acc files can only be used on Apple products. The mp3 format is much more pervasive and can be played on virtually all systems. I use iTunes to add the album art and text by copying the mp3 file into iTunes and then right mouse clicking on the entry, selecting Get info, and then using the Artwork tab and the Lyrics tab to add the album art and text respectively.

The last stage involves uploading the file using FileZilla, another great free Open Source program. I use Podbean for my podcast hosting. They have a free version to get started. I use Podbean to create the requisite rss tags. I first had to submit my podcasts to iTunes (and the Zune Marketplace is available to do that too) but after that, the podcast episodes automatically appear in iTunes and are delivered directly to subscribers as well.

I've tried to be detailed in my description but if any of this wasn't clear or you'd like to contribute your own experiences and recommendations, please feel free to use the commenting facility below to continue the discussion. Happy podcasting!

Social Networking: The Walled Garden

Like many of you, I'm on the major social networking systems Twitter and Facebook and also contribute content on this blog, two podcasts, and two websites. The problem I see is that each of these systems is a walled garden. Podcaster Leo Laporte has been talking about this in general lately too. When I write a post here, people read it and make comments on the blog itself. I also tweet about it on Twitter and send it as a link on Facebook. The latter two also often generate further discussion within Twitter and Facebook. The blog content is picked up by other sites and blogs which leads to further discussion there. The problem is that nothing pulls this all together. Readers of this blog don't see some of the great comments followers have tweeted on Twitter or friends have left on Facebook unless you follow me on Twitter or are a friend of mine on Facebook. Add to that, the comments regarding podcasts which are in iTunes and on the respective show notes sites.

It is interesting to point out that this mostly relevant to comments made rather than the originating content. Tools like TweetDeck allow you to post content to Twitter and Facebook accounts and blog posts and podcasts themselves are syndicated via RSS but the comments about any of this content remains within the social networking walled gardens. To continue the analogy, it is like the hosts of garden parties freely walk from one garden to the next but their guests have to stay within the walls of their designated parties.

A solution here isn't obvious and likely is being worked hard by people at Facebook, Twitter, and Google. The challenge is that some of these systems are wide open like Twitter while others are closed like Facebook. While Facebook is working on making itself more open (and the recent purchase of FriendFeed will likely expedite this), I still think that it needs to tread carefully. Rather than making everything wide open on Facebook, my vote would be to have a checkbox on a post or comment indicating that it can be shared or perhaps a more pervasive option but one that is still under the control of the user. Then we also need the ability to aggregate all content related to a particular topic. For example, all comments about this blog post whether they were written in the comment box here or a reply on Twitter, or a comment in Facebook would appear or be directly accessible from each of those sources.

As always, I welcome your thoughts - using whichever walled commenting system you'd like.
