I’ve been running Parallels on my Mac Pro, but I decided to check our VMware Fusion on my new MacBook Pro. I’m using Windows XP Home Edition in both cases, just so that I can run IE6, IE7 and a few other Windows programs. So far I can report that VMware Fusion has a simpler installation process. Not that Parallels is difficult, but it’s actually easier to install Windows XP under VMware Fusion than it is to install XP on a native machine. So far, not a single glitch.
I was interviewed by Corey Pudhorodsky for his 501c3Cast podcast [mp3]. The interview begins about 12 minutes in.
Lots of activity next month in the PodCamp world. If you’re in Kansas City or Nashville, this is your chance to get together with other Podcasters. Fun and informative!
I was interviewed today for the Digital Media Dude Meet the Experts podcast. It’s already online.
Starting early this morning I was unable to send any email from my Mac. Late this afternoon, my wife said she had the same problem. I did some testing and determined that I couldn’t send to any SMTP host (not just Comcast’s host) on port 25. I could send email from my Gmail account, but that’s browser based. I did a little surfing and found a thread on Chris Pirillo’s site in which others have had the same problem.
It turns out that Comcast has blocked my outbound traffic to port 25 on any server. Did they inform me? No. Was there a reason for doing so? No. I use the smtp.comcast.net server for outbound mail, as they told me to when I signed up for their service years ago.
I called Comcast support and spoke to a useless tech. He said I should call Apple because there must be a problem with my Mail program. Oh, and my wife’s, too, of course. But the Lockergnome thread suggested I call Comcast’s security department at 856-317-7272, which turned out to be a good idea. The first thing the automated system tells you to do is go to www.comcastsupport.com/alternateport and download the OneClick fix. Okay, except it’s specific to Outlook Express. Doh! Another call to the security guys to talk to real people. These folks at least know what they’re talking about, and I was able to get back up and running.
Apparently, this is part of some ongoing program. Comcast disables outbound traffic to port 25 at the drop of a hat. Other ISPs do this, too, although I would hope they’d communicate first with their customers. The fix?
- Configure outbound email to smtp.comcast.net, but on port 587, not the default port 25.
- You must use password authentication for outbound/SMTP. Unless you’re using your ISP’s web mail, you probably forgot your username and password, so you’ll have to call the ISP to get them.
- Do not use SSL.
Alternatively, just do what so many people are doing and use Gmail.
Two weeks ago I implemented the ETCO frame in the ID3 tags of The Conversations Network’s MP3 files. Tonight I re-implemented the Excerpt/Clip feature as well. Here’s an example of a URL that plays a specified excerpt from one of my favorite IT Conversations interviews: one I conducted with security expert Bruce Schneier back in 2004: http://www.conversationsnetwork.org/clip.php?showid=119&start=9:57.2&stop=10:26.5. Note that the start/stop times can now be specified within fractions of a second. Go ahead — click on that link and see what you get.
Google has just announced Google Presentations, a feature of Google Docs that supports slideshows on a web page. Unlike SlideShare.net’s Flash-based offering, Google Presentations uses a far simple DHTML-in-an-iframe implementation. I like the simplicity of Google Presentations, but I’m skeptical that there’s any way to extend it to support synchronized audio.
Executive Producer, Phil Windley has posted his list of the top-ten IT Conversations shows for 2007:
- Bruce Johnson – Technometria: Google Web Toolkit
- Robert Trivers – What Do We Know
- Maryanne Wolf – Tech Nation
- Eben Moglen – Freedom Businesses Protect Privacy
- Jared Smith – Technometria: Open Source Telephony
- Beth Kanter – Jon Udell’s Interviews with Innovators
- Guy Kawasaki – The Art of Innovation
- Rob Levy – Tech Nation
- Vint Cerf on Technology & Digital Culture – IEEE Spectrum Radio
- Dick Hardt – Jon Udell’s Interviews with Innovators
We used to have an awesome excerpt/clip feature that I implemented after experimenting and discussing with Jon Udell. But when The Conversations Network started using an automated show-assembly system, we had to disable it. The reason was that our programs began to include intros that could change on a daily basis, and any reference to a specific time in an audio file might be be invalidated whenever the content of an intro was updated. As I proposed in 2006, I’ve now added the ID3 “ETCO” frame to the ID3 headers of all programs on The Conversations Network.
I hope to eventually reincarnate the clip/excerpt feature. In the meantime, I want to let people know it’s there, in case they want to use it or — wouldn’t it be great — adopt it as a standard way of documenting where the body of a program begins. Someone could even develop or enhance a Flash player that skipped all intros! I also hope it will be adopted by others such as SlideShare.net so that we can produce synchronized audio/slide presentations that support our variable-length audio-program intros.
For those who want to read our ETCO frames or write their own, the official syntax I’m using is as follows:
"ETCO" Header for "Event Timing Codes" $02 Absolute time, 32 bit sized, using milliseconds as unit $03 Type of Event (mainpart start) <32-bit int> Offset in milliseconds as a 32-bit 'synchsafe' integer
