Nor in Australia

I was going to give blood with the rest of the office and they just looked at me and laughed :(

You dare us replacement...

I meant to mention this a while back but never got around it.

Could you do a pro-longed 'You dare us'? Like the game that you had to write, could you do something that you'd know would take a while to complete and have fortnightly updates on how it's going?

... And 've just found out how to create an account, yay :)


sabayon, the traditional southern french dessert.

*ogg.ogv vs. *.ogg

*ogg.ogv vs. *.ogg - NO!

I give up. I used to try to download podcasts in OGG because it was open-source, and I like the free open-source nature of the OGG format, even going so far as to buy a MP3-player that plays it.

But, formats change, and I get the hint; download in MP3 if you want the format to work.

Yes, we are annoyed...

@not a french Penguin

Nope, it's italian.


I believe the blood thing applies to Canada as well. It was at least one of the questions you had to answer on the donors form.


If you're interested in finding out more about bitcoin Linux outlaws, did a podcast special on it last week, it's long and pretty comprehensive.

Also, I'm glad to hear a tutorial on mpd is the pipeline it's fully awesome.

That penguin is awesome.

That penguin is awesome.


something to listen to on my way down to pembrokeshire tomorrow... wooohooo!

cool penguin

fair play on the penguin!

On Firefox addon's

Thing is, they *don't* change the API (all that much at least) between versions. They just do a version check of the extension. Personally I run the nightly builds of Firefox, and have simply set the "nightly.disableCheckCompatibility" option in the about:config page to true - and everything just works.

What *should* happen (in my opinion) is some sort of automated testing of extensions at addons.mozilla.org prior to a new version being released. If the extension doesn't break the new build, it's supported version tag should be extended, and it be updated at the same time as the browser is.

Extension authors could be notified that their extension was automatically enabled for new versions of Firefox, and given the option of overriding that.

Just my 2c.

PS: Firefox Nightly is *brilliant* - and incredibly stable. Who needs version numbers when you can have yesterday's date?

@anOminousEudyptula and the podcast team

I'm a Firefox extension developer, before each release (since the 4.0 release) they have emailed me a report regarding my extension confirming that it is compatible with, and informing me that they've automatically updated it to allow it to be installed on the next release.

The extensions do no break, and I do not have to manually update my extension. Basically it works exactly as anOminousEudyptula said it does.

I'm really disappointed that you all chose to bad mouth Firefox over this when clearly none of you have bothered finding out.

Podcast, Bitcoin, and PLE

Great podcast - nice to see Effy back.

@Thameslink (bitcoin) - I wouldn't use the LinuxOutlaws podcast as a reference for BitCoin. By their own admission it wasn't one of their best - instead go to grc.com/sn and find episode 287. Not only is that a more detailed explanation, it's also easier to follow.

Re: PowerLine Ethernet. Couldn't agree more that it's a great technology, used both Solwise and Devolo adapters and it's way more reliable than WiFi, (using Devolo now). One point though, the PLE folks have always said that their signals aren't transmitted through the consumer distribution box - so there's no chance of someone on your street picking up your net traffic. Shared infrastructure (e.g. in flats) is a different matter, and I'd switch on the encryption anyway - there's not that big a penalty.

BTW, has anyone else had credibility problems converting someone to Linux? Just persuaded my sister to switch from XP to Ubuntu Natty and she just couldn't believe that (a) she didn't need to buy an antivirus product and that (b) all OS and apps were free. She's been amazed how well it's working - especially when her Epson printer was setup automatically when she first plugged it in (no need to load drivers like XP).

Déjà Dup Does Not Work! & Firefox Extensions

Déjà Dup Does Not Work!
Once you have done one backup, all you can to is update that backup. You can't do home and then photos and then music and then videos and then downloads. If you can please please give us a tutorial. I uninstalled it and deleted the files it created and reverted to using tar.

Firefox Extensions
I still use firefox4 because my extensions are broken in 5.
I am only a home user. We all want the same thing, the best possible experience when using a browser or any other piece of software. Options, security, extensions, stability and configuration are all part of the experience that we want, expect and have become accustomed to.

Idea for show.

Instead of having the same show format every time, why not follow in the modular footsteps of linux? Have several show modules in a hat, and pick four of them out at the beginning of every show. Add anything you want to the hat, and give the listeners a bit of variety.

For extra points, add module dependencies and make the show fail when a dependency is missing.


Bring Back Contrary To Popular Wishes

And, on second thoughts

If you use Unity or Gnome3 the way it was intended to use, then you will get used to it better. Think of it like an iPhone - use it how the devs want it to be used. I used Unity and Shell, and like both

I dare you

I've got a dare that might work: A while ago you guys did a "you dare us" that involved contributing to an open source project. And in the last podcast Graham bemoaned the lack of documentation wrt Kate's snippets plugin.

Why don't we combine the two? Contribute documentation. You guys (except for Effy) write for a living, and you write a lot better than most programmers. Could you submit to a project some of the stuff you've already written, so that they can add it to their documentation? A lot of projects could use the kinds of tutorials that appear in LinuxFormat.

What do you reckon?

Google, Chrome and extensions.

First, thanks for an amazing podcast.

Second, please stop spreading !"£$%^ - stop calling what you mean to call extensions/add-ons plug-ins - add-ons != plug-ins. Plug-ins are libraries that allow extra content to be displayed in the browser like Acrobat, Flash, etc. Add-ons are extensions to the browser, like Google Toolbar, Add Block, etc.

Third, the reason that add-ons work so well between releases of Chrome is because they're not really add-ons. Chrome 'add-ons' (which are, basically, glorified bookmarks/html5 pages) have no where near the same degree of access to the browser as Firefox add-ons. With Firefox add-ons, the developer can basically change whatever they want in the browser (hence why some add-ons are likely to break) unlike in Chrome where the degree of access to low level awesomeness is much lower.

Fourth (and finally), just to extend on what anOminousEudyptula and buzzomatic said what most people have been complaining about is Google Toolbar not working in Firefox 5 - none of this is Mozilla's fault - it all lies with Google, the trouble is Google Toolbar isn't hosted on AMO (addons.mozilla.org) therefore meaning that the automatic script to go through all add-ons on AMO and check if they'll work with Firefox 5 (and if not, start sending emails) couldn't operate on it. So, yeah, blame Google.


Sabayon is indeed French. The Italian name is "Zabaglione", and the recipe is likely an Italian invention, as it is a simple blend of egg yolks, sugar, and Marsala, which is of course from Sicily.

There are both sweet and savory versions (you can omit the sugar, add herbs, stock, and use dry Marsala in lieu of sweet - it makes a lusciously rich sauce for meats, and is rather like a more complex Bearnaise sauce) and it can be used as a standalone dessert, or as a sauce for light desserts (you just adjust the recipe to make it a little thinner).

If you make the sweet version for a stand alone dessert or for a sauce for berries, cakes, tarts, etc., you want to make sure you have all of the updated KDE libraries installed, as well as the PPA for egg yolks.

The savory versions should have no missing dependencies on any modern Linux system...

second the zsh-thing

Well if you like the bash,
you will love zsh.

If you want a battery included thing. Try the zsh config of the gmrl distro (cool by itself)


2 weeks with zsh was the you dare us in season 2 ep 7.

There actually is a pitours.com

You Dare Us

How about coming up with a decent name for GIMP i.e. one that might be acceptable in a commercial or family setting.

@ Michael (Xendros originally, now Mint) (not verified)

Anything with the word "Manipulation" in it is always going to sound a tad manipulative ergo not very family friendly.

The word Family often conjuring images of Children, Fathers, Mothers and the word "Manipulation" often conjuring images of Catholic priest's & children.
What any of this has to do with The GIMP is open to in·ter·pre·ta·tion. Id say it was something to do with Image Manipulation.

nome for gimp

I would suggest -> Digi tArt


Your post is basically true except for,imho the, "AARRGGHH! GO AWAY!" and so, I guess, and I'm just guessing, that the purpose of diaspora is not to rival commercial social networks but to show and invite people to experience different paradigms on social networking. I believe that diaspora like many FLOSS projects as the advantage of being open to choice and, for that same reason, condemned to niches.

@diaspora Penguin

Yeah, undoubtedly. Don't get me wrong; I'd LOVE for there to be an open alternative to Facebook. I use Facebook very grudgingly because practically everyone I know (or at least care about) uses it so I'd be out of the loop if I didn't. But if there was a strong open alternative that I could persuade people to switch to I'd be unrelenting in my efforts. Sadly, Diaspora isn't it because it wouldn be too difficult for average users to grasp, and even seems to revel in that. Shame.

Wizard of Oz / bitcoin

Cool info on the Wizard of Oz, and currency, etc. So does anyone here use Bitcoin? I have only previously heard of it on the One Radio Network show on money with Andrew Gause. And in a world of free open source software, is money even relevant?
