The Internet is a cornucopia of useful resources for software developers and marketers. As well as all the documentation, forums, blogs and wikis there are some great audio and video resources. Here are some of my favourites:
NerdTV – Robert Cringely interviews famous names from the software industry.
Shareware Radio – Mike Dullin interviews shareware authors and microISVs in his inimitable style.
The MicroISV show on channel 9 – Michael Lehman and Bob Walsh interview people of interest to microISVs.
.Net rocks and Hanselminutes – Carl Franklin and Scott Hanselman interview people of interest to .Net/Windows developers. Some of the programs are Microsoft-heavy Silverlight/Orcas/WPF alphabetti spaghetti yawn-athons, but others are of more general interest.
TED talks – The great and the good talk on a wide range of subjects, including technology.
These sites contain hours of great material. Long drives/walks/waits need never be boring again. Please add a comment if I have missed any good ones.

No mention of IT Conversations? Quite a few good podcasts there.
And yes, congrats on getting ‘press coverage’ in Guardian. :)
I’d second IT conversations for a more general resource for tech stuff. In particular I find Jon Udell’s “Interviews with Innovators” very worthwhile.

Recently I’ve been loving the youtube videos from Ed Dale:

To anyone looking for internet marketing ideas I suggest watching his most recent 30-day challenge videos. I’m half way through and completely sold. Very easy going, but with plenty of good ideas.
I wasn’t aware of “IT Conversations”. Thanks for the tip. I’m listening to one of the talks now (Will Wright on games).
It would be interesting to compile a similar list for
Marketing geared towards small business selling online,
it’s very hard to find the little Gems since the word Marketing is often affiliated to zillions of scams and self-proclaimes Marketing guru with absolutely no track record under their belt.
