Podcast Season 2 Episode 13


Title: Live from OSCON.

In this episode: A SCO representative finally reveals some of the Linux code SCO had a problem with and OpenSUSE 11.3 is here. Listen to the results of our new challenge, and we ask whether the likes of Red Hat, Novell and Canonical contribute enough back to the community.

What's in the show:

  • You Dare Us:
      Hear our extra special challenge for this episode, and view for yourself our amazing videos created on Linux devices.

    • Graham:
      • This was shot on a flight between Vancouver and Portland, on the way to OSCON, and shows the bizarre strobing effect the propellers have on the video input signal. Edited using OpenShot.

    • Paul:
      • After being inspired by Hot Tub Time Machine, Paul's video features his own solution to the Rubik's Cube.
        Download as H.264 (84MB).
    • Andrew:
      • Andrew's video offers a rare glimpse of life in and around our office at Linux Format Towers.
        Download as H.264 (16MB).
  • News:
      SCO has finally revealed the lines of code it feels were stolen and inserted into the Linux kernel, while OpenSUSE 11.3 is here. Well done Novell! Even better news comes from Opera when it announced the release of version 10.60 of its super browser, featuring embedded support for Google's WebM video codec and lots of speen improvements.
  • Discovery of the week:
    • Paul:
      • 'sudo -K' clears the sudo password cache.
      • Micro USB looks confusingly similar to mini-USB, in a good way.
    • Andrew:
      • LiveCDs are great for partition management with GPartEd.
    • Graham:
      • Get knitting with Knitter 0.5.5. It's most excellent because it produces a 3D representation of a knitting pattern and supports KnitML.
  • Closed Ballot:
    • Do the likes of Red Hat, Novell and Canonical contribute enough back to the community?
  • In the Hot Seat:
    • Andrew steps in to help an absent Mike for this episode. Well done Andrew!

Linux based recorders

Hi guys... just wondering what devices your videos were recorded on?


We used HTC devices (a Desire and a Legend) and a bit of Ubuntu.

LF Towers

what a dump. I think you need to do a car boot sale. get rid of some of that clutter.

H&S@W Act

Now who is the Health and Safety Officer for LXF Towers?

For your sakes I hope the HSE aren't Linux users!

You dare us

I agree with johnvile... it is a dump.

For your next challenge I dare you to tidy up your workstations!

Andrew's video

I enjoyed Andrew's tour of LF Towers. It would have been nice if he had shown us the podcast recording suite where you make the show, however.

Thank you

In keeping with the general spirit of positivity, thanks lads for yet another blistering podcast. The "Tuxradar" podcast and the "KDE and The Masters Of The Universe" podcast are my two favourites.

Being positive

Will you be as positive in 2 weeks time when you will presumably be discussing the by then released KDE SC 4.5?

You don't know whose desk that is?

And yet yours is the next one along.

How can you possibly work in an office for any length of time and not know who sits next to you?

'The' Gimp

I noticed in the podcast that you referred to Gimp as The Gimp, with an appended 'The'.
This has become pretty universal when referring to Gimp. As far as you can remember has this ever been applied to any other piece of software? The Chrome? The Firefox? I could not think of one :)

ubuntu contributing back

Correct me if I'm wrong.

Red Hat work on gnome shell, nouveau graphics drivers, plymouth, theora, vorbis and other codecs.

Novell work on Banshee, Mono, Evolution and are the biggest contributors to KDE.

What prominent software have Canonical produced?
I ask this out of curiosity - not to have a dig at Canonical.
I can see Canonical using Red Hat and Novell developed technologies (not to mention Debian), but am unaware of stuff that Canonical has developed which has featured in Suse or Fedora.

Could anyone enlighten me?

Excellent podcast

Challenge met and handled brilliantly. Congratulations. Much better being constructive, although I realise that perhaps it's harder than I first thought. Still, hat's off to you all. (Except Mike, perhaps?) --- no, sorry. Just kidding!

Hope OSCON is fun, bring back lots of good articles and interviews. Any consideration of attending one of the Australian LinuxConf's in January?


Mike. (Mihaly is michael in Magyar).


wow, you were even positive about ms.

Podcast Awesome-ness

That was a brilliant podcast. I cannot believe how awesome it was. In fact I do wonder if that podcast contained the largest occurrence of the word "Awesome" ever.

It sure felt like it.

I would like to challenge you to not use the "Awesome" at all in the next podcast! :P

Have fun

I double dare you! Is that redundant...

...seeing as how I have already dared you once?

In any case, I still dare you to use Puppy linux for a fortnight when you are all back together...

This episode was "positively" excellent, but again too short. You really need to consider making TR a weekly podcast. If nothing else, it will silence the critics who are somehow offended by the term "fortnight"...

Follow-up on the videos

Paul's video was absolutely AWESOME!!! I had forgotten how to do it, but years ago I held my local school record for solving Rubik's Cube within a few minutes. Rubik of course was a Hungarian, and also developed quite a few excellent puzzles, possibly the next most famous one now is a GL screensaver - "The Snake".

I of course no longer have any of the puzzles, and probably would have to work a bit before getting back to even basic level moves, but the description and explanation and demonstration Paul has done is certainly very good. It put's Andrew's to shame ... come on, andrew, the challenge was to "do something with the video", you didn't even edit it!

Not sure, but I was under the impression that the effect you see arises from something called a "moire", which is a result from the film "rate" of the camera crossover with the rotation speed of the fan blades. At least I am sure this is the case for the screen "folding" you see when filming CRT screens - there is even a switch on one of my "el cheapo" cameras that will switch between a 50Hz and 60Hz camera rate - presumably to do with which country you are in and hence what AC current frequency is local.

I could be entirely wrong, take this with a lot of salt.

Anyway, only Paul's video was encoded as OGG video!!! Unfortunately, 80Mb took over 4hours at dialup speed.... meh. It still was worth it!!!

Re: Theora

Yes, Graham's was the only one to use Theora, but to be fair he did have a much better phone than us!

Andrews Video

*cough* Pedobear? *cough*


Quite right, I realised just after I'd posted - as is always the way - that I had incorrectly singled out the wrong video in terms of which was using what codec .... Sorry...

Actually, you're correct, strobing is probably the better description, and as I said, I wasn't certain I was right, so my bad I guess. Indeed it's quite an interesting effect and given my fear of flying, I doubt I'll ever see such a sight myself - just give me the drambuie and wine and let me pass out like that bird from the "West Wing" - leo mcgarry's assistant played by Gwen Chenoweth - never mind.

I don't wish to only be seen as pedantic either. It's hard enough to be close to correct without being considered some sort of smart-alec. That really isn't why I respond. I just kind of feel like maybe I have something to contribute.

I'm more like "Rimmer" than "The Cat" from the sci-fi parody "Red Dwarf". But I'm still dipping my toes in goldfish-o's.

I obtained "Mandelbulber" and have been having lots of fun with that particularly interesting piece of software, though it really needs a full-quad core and many more MB than I have of memeory (HaH!).

I've been a fan of Fractint - I still use it to this day! And also love Xaos for sheer brilliance, loved Arthur C Clarke's exposition on fractals, and - believe this?

I have Mandelbrot's autograph from a Chaos Convention he attended in 1988 in Sydney, along with several other attendees signatures in my papers - I asked each guest to sign their paper in the colloquium. Don't think it's particularly valuable, but anyway.

What I was going to say was that I was interested in what you had done, and are you going to explain the various editing tricks you used in your video? The titling, and the background/overlay stuff was interesting.

You did speak in the podcast about the various issues with H.264, say against Vorbis, or whatever, perhaps this is something that should be expounded upon, pro's and con's, how it relates to say us mere mortals using video cameras, what's available in terms of what you can get from certain products/manufacturers - is it valid to justify a purchase of camera Y vs X based on what each provides?

I know my cheapo camera does both video and also something called moving Jpeg .... these are areas I would like to understand better.

Mucho gracias and look forward to next podcast.
BTW, you're off the hook, as far as I'm concerned, whether a joke or not, I appreciate the positive way you took up the challenge, but if any of you feel the need to be critical of stuff, you can be from now on. To be honest I was just upset with the continual bagging, and felt strongly enough to write in the first place, but I realise it's going to be an ongoing joke from now on.

That's fine, fine, fine. (in the voice of Eccles).

Bring it on.

Macpodcast - Arghhh

I decided to download the mac podcast, wish I had never
wasted my time.

It sucks - sounds like an advert.
Oh that's right ... it IS an advert.

They sound like the kind of people that make microUSB
sound like a great idea. Yeah a great idea that sucks.

Give us a break. I'm sure the same marketing "geniuses" came up with the name for our local festival demonstrating the wonderful variety of cuisine on offer here: they call it
"Bankstown Bites".

No sense of irony, apparantly.

Actually there was fun for all, and excellent food on offer so I can't be too critical. But seriously - "bites"??!

Why not "Bankstown Food Festival" - huh? What's wrong with
that? But no, it had to be alliterative and marketable, so
we get: "Bankstown Bites". Well, you had to be there.

It certainly does.

This "positivity" BS has got to go!

That was the smarmiest, butt-kissingist episode ever. Give me back the sarcastic bastards we've known and mostly liked ;-)

Hooray for Powells

Thanks for plugging Powell's City of Books in Portland (perhaps the greatest bookstore ever). That's 2 years running, as you mentioned it last year after attending OSCon. Hope you had a great time in the Rose City.

Hooray for Mt Rainier

Great shot of Mt Rainier in the background of Graham's video. Makes me miss the Pacific Northwest and Western Washington.
