Hello, and welcome to the Ubuntu UK Podcast! It’s Tuesday the 1st of March 2011 and with me this week are….

And with (something like) that, this Tuesday at 8.30pm (UK time), we’ll be kicking off Season 4 of the Ubuntu-UK Podcast. And you can listen along. Live.

Regular listeners might be aware that we attempted a couple of episodes live last season. It mostly seemed to work. The weak excuse for broadband in Studio A held up well enough that we’re going to give it a go properly. So every two weeks, you can listen along with us live on the Internet.

While you listen, please join us in the chat room, on Twitter or identi.ca and offer feedback and other contributions as we go.

If you’re new to UUPC, it’s a one-hour Internet radio show on which we mostly talk about stuff relating to computing and the world of Open Source Software. If you can’t listen live on Tuesdays, you can download the show as a podcast from our website or from iTunes. We’ve been called “the Radio 4 of Linux podcasts” – basically, we’re family-friendly (no swearing) so you can listen around the house or in the car. We like to think we’re entertaining and a bit humorous. And we drink tea and eat cake when we can (though not while we’re talking!).

If you’re curious, have a listen to a past episode or to Tony’s Episode 0 teaser which he released last week.

See you Tuesday for:

I spent the next hour absorbed in reading the Human Library website and the WOMAD website on my mobile phone. Then:

And:

So:

And that was that. I was committed. In public.

The Human Library is a fascinating idea that originated at Roskilde Festival 2000 in Denmark:

Borrow a person you normally would think you would not like. We have a wide selection of unpopular stereotypes. Everything from gays to hip hoppers to immigrants. Take a walk, have a talk or dont. Just remember to give back the person within two hours.

As a book, I had to have a blurb to be printed on my metaphorical back (in practice, it was to go into a printed catalogue of the available books for visitors to browse). The idea of the blurb is to be controversial and encompass some of the popular stereotypes about the subject. At which point, I started to struggle. So, I turned to Twitter again:

Initially I got self-consciously positive comments about women in IT such as:

actually the best IT Manager I ever worked for was female

Whilst a nice sentiment, it wasn’t quite what I was looking for. So I tried again:

I figured an example or two might be helpful to get the ball rolling:

That seemed to do the trick:

As you can see, there were quite a few responses, once unleashed. You can probably also see that some of them contradict others (eg ‘love pink’ and ‘not at all girlie’). I think that just goes to show that whatever you think about girl geeks, you’re probably wrong.

Anyway, thank you to everyone who helped crowd-source my blurb. You can read my published blurb on the Human Library at WOMAD website.

My next task was to un-earth my 15+-year-old tent, and put it up in the back garden:

And I bought some purple festival wellies on ebay.

On the weekend itself, I pootled up to Charlton Park, the venue for WOMAD 2010. After some difficulties with the lack of signage and not being able to find the right entrance, I was presented with not only a free weekend ticket but a CREW pass and backstage privileges:

Which, once I’d found Katy (@littlecough), I discovered meant that I could pitch my tent in the crew’s campsite. Basically it just meant I had to walk further but I could go pretty much anywhere and there seemed to be a higher ratio of toilets and showers to campers. I appreciated that a lot throughout the weekend.

So, the Human Library. Well, I had two 2hr sessions on the Saturday. The Human Library was based in a couple of pretty yurts on the edge of the festival.

It was a slightly odd experience being a book. It felt a wee bit like we were being pimped out – 8 of us books sitting out of sight on The Shelf (a row of chairs by the door with a label around our necks). The customers signed up at the desk outside the yurt and were then led inside to meet their book who would then take them to a free table and cushions somewhere in the yurt, or outside on a bench to chat for 30 minutes.

Some books were instantly popular, like the Tsunami Survivor and the Psychiatrist, who both seemed to be booked out in advance for every half-hour slot. On paper, it was less obvious what a Girl IT Geek was so I tended to be the pot-luck book; people who were interested in the Human Library and wanted to try it out would often just pick one of the books not currently out on loan.

I don’t think I got any advance bookings at all but I was borrowed for most of the slots. I found that I was every so slightly nervous at the start of each of my ‘readings’ because I don’t usually find it very easy to just start a conversation with someone, even though I’m usually happy to talk to random strangers who strike up conversations on trains. My first borrower was an academic who was, himself, slightly apprehensive, I think, and very serious. We had an interesting discussion about energy use and flying. He pointed out that academics typically made their careers from becoming experts in very very specific areas, and then it’s a career highlight to arrange a conference in that area in an exotic location that you have to fly to. We discussed how video-conferencing could be improved and the problems we’d each experienced with it.

After that it becomes something of a blur. I talked to a primary school teacher about energy monitoring and how it can be hard to reduce household energy usage when you share with friends. I talked to a musician about Open Source Software (he’d tried Ubuntu but didn’t think it had the software he needed for his music) and the software we use to produce the UUPC podcast. I talked to a single mum from New York and her young daughter about using computers and how awkward it is to get photos off a camera, on to your laptop, edit them, upload them. And I did a joint booking with the Vegetarian Ecologist for a group of teenage boys with whom we discussed Second Life, Open Source Software, home automation, and agreed that my Christmas tree lights project really was very geeky. (You can see me as a book in one of the photos on the Human Library at WOMAD website.)

It actually went really well, though it was exhausting. In all but one of my bookings, we were still happily chatting away when the 30 minute bell rang to say the session was over. In the one that finished slightly early it just came to a natural end of conversation, which was fine. Over all my bookings, I think I probably ticked all the boxes of things I’m interested in and have blogged or tweeted about at some point…usability, climate change, energy monitoring, Open Source Software, Ubuntu, my Christmas lights project…

In the odd session when I stayed on the shelf, I chatted to some of the other books, including the Dyslexic Egyptology Student book, who was inspiring in what she does, and it was fascinating to listen to her talk about her life as the daughter of the Council Tenant Mum of 7 book. The Dyslexic Egyptology Student also had a great story to tell about some ace young girls who borrowed her and shyly asked her about her dyslexia and whether she’d got bullied about it and whether she thought they could go to university as they too had dyslexia.

The sessions all ran really smoothly and the yurts were lovely and shady from the hot sun outside. I really enjoyed being a book and would recommend it as an experience to anyone. I think it would also be a brilliant way for a company to do diversity training. A few weeks later, I read a profile by a guy at work who has multiple sclerosis; the insight I got into his life just from reading that article had a similar effect on me as listening to some of the books talking at the Human Library.

As for the rest of the festival, I ate breakfast at the frightfully middle-class Riverford organic cafe (as in the delivery people), and learnt how to plait garlic (a fine skill, I feel), though I didn’t win the Riverford garlic-plaiting competition. I ate loads of vegetarian food from the various vans and stalls, discovered the lovely hot apple and cinnamon at the Tiny Tea Tent:

And watched the bubble experts (as seen on Blue Peter many many years ago making massive bubbles around small children):

As I left Charlton Park on the Sunday afternoon, leaving the WOMAD 2010 music festival, I realised it was the first time since Friday lunchtime that there was no soundtrack. Since I arrived on Friday, there’d been a constant music bed of drums, singing, guitars, or PAs. WOMAD wasn’t somewhere I would’ve gone had it not been for taking part in the Human Library but it was a fun experience, and I saw both Cerys from Catatonia and Chumba-wumba live (she sang Mulder and Scully; they refused to sing Tub-thumping). Sadly I missed the Ukulele Orchestra of Great Britain.

On Ada Lovelace Day, today, anyone and everyone is encouraged to blog, podcast, videocast, tweet about the achievements of a woman in technology and science.

Laura Czajkowski

I met Laura Czajkowski last September when part of the Ubuntu UK Podcast team shipped off to Dublin to attend her OssBarCamp conference, have a weekend of geekery, and an evening of BBQ and cocktails. Since then, I’ve seen Laura working passionately to help kickstart the Ubuntu Women Project and I’m aware that she is also on the Ubuntu NGO project which looks at how to make it as easy as possible for charities, not-for-profits, and other NGOs to benefit from Ubuntu and Open Source Software.

After I tweeted a few weeks back that I was working on OggCamp10 planning stuff, she replied, offering her help. I wasn’t sure how serious she was but as we had a load of large tasks that needed doing around that time, I figured it was worth asking. Within a week, she was a fully signed-up member of the OggCamp planning team (ie she gets all the emails and can edit the wiki), despite having her own conference to organise as well. OMG Ubuntu published a great interview with her today.

Ana Nelson

Another ace woman I met in Dublin that weekend was Ana Nelson, who Laura had finally convinced to present about her documentation automation work. I swear (as a former technical writer), the stuff she develops on should be used by corporations everywhere to maintain their vast documentation libraries and to save their skillful writers from spending hours manually updating screenshots and code snippets. Her talk at OssBarCamp was fascinating and understated – she sat on a chair, speaking her way round a printed, illustrated mindmap, punctuating it all with physical props like wooden toys and knitting needles. Her tweets are no less insightful, witty, and slightly off-beat.

So they’re just two of the women in the Open Source world (in particular, the Irish Open Source world) who’ve inspired me recently. Go check out their blogs to find out more.

This week, I decided to install Rational Software Architect so that I could try out (again) the User Interface Generator which comes with IBM InfoSphere Master Data Management Server–and other products too, I believe. You can find out more about what user modelling is and how you can use the UIG in RSA (lovin’ the IBM TLAs yet? ) in this series of articles on developerWorks. The rest of this post is not about the UIG but about how to install and configure Rational Software Architect for WebSphere, which is relevant to anyone wanting to do this, regardless of whether they’re wanting to use the UIG.

So I wanted to install Rational Software Architect (RSA; an Eclipse-based piece of software) on to Ubuntu, which is what I run on my work machine, a Thinkpad T61p. Not only that, but I wanted to install RSA for WebSphere, which includes WebSphere Application Server Test Environment (WAS). This meant that I was installing not one but two pieces of software that are not officially supported for Ubuntu Karmic (or indeed for Ubuntu/Debian as far as I know). But as the Linux binaries are .bin files rather than .rpm, life should be easy.

And indeed installing it is. It’s when you want to create a WAS profile that the fun starts. And that’s where it had all fallen apart for me when I tried much the same exercise this time last year. That time, I gave up.

This time, I tweeted my predicament, knowing there were people who might know the answer. Unfortunately, the person I thought might know the answer had failed in much the same way as me only 6 months ago and was now relegated to using Windows. Still, others came back to me, including Gavin Willingham, who I’d not met before but who works possibly 10 minutes walk from my desk, and Jay Limburn, who I’ve known for a year through Twitter and internal instant messaging but, though he also works max 10 minutes walk from my desk, never met in person until yesterday (he’s shorter and blonder in real life).

So, if you’re trying to install RSA for WebSphere 7.5.4 with WAS Test Environment 7.0 (other versions probably work the same way), I’ll end the suspense and start here:

Running the installer

1. Download the many parts of RSA for WebSPhere 7.5.4 and WAS Test Environment 7.0 with licence/activation bits and pieces. (NB this isn’t free software; you have to buy it from IBM so I’m assuming you’ve got that far by now.)
2. Extract all the zip files. If you do a right-click > ‘Extract All’ on the zip file in Ubuntu, the extraction tool doesn’t like to overwrite directories of the same name, so you end up with directories called ‘RSA4WS’, ‘RSA4WS (2)’, ‘RSA4WS (3)’, and so on when actually, you want the contents of each of those directories to be in the same place. So move the directories around so that you have just 3 directories:
   • RSA4WS (contains 7 directories called ‘disk1′, ‘disk2′, ‘disk3′, etc)
   • RSA4WS_SETUP (don’t do anything with the contents of this one)
   • WAS70 (contains 4 directories called ‘disk1′, ‘disk2′, etc)
3. In the RSA4WS_SETUP directory, as sudo, run launchpad.sh to start the installation process.
4. Follow the installer through but when it asks you for a user name and password to create a WAS profile, select that you will create a profile later and that you don’t want to create one now. The installation should run cleanly (if you let it try to create a profile, it will fail part-way through the installation).

You should now have a nice installation of RSA with WAS on your Ubuntu box. Next, you need to create a WAS profile so that you can use the in-built WAS server for development and testing (or in my case, to run the user interface generator).

Creating a WAS profile in RSA

There are a few things that prevent this just happening (some are generic Linux things and some are specific to Ubuntu):

• On Ubuntu, /bin/sh uses dash, not bash, but WAS scripts seem to use bash specifically, so the profile creation scripts fail.
• Something extra that I have no understanding of is required in the eclipse.ini file (which is key in starting the Eclipse-based RSA environment).
• The default location in WAS’s profile creation wizards is in the /opt part of the main file system which you typically won’t have write-access to as a normal user.

So here’s what you need to do (at least, this is what I did and hopefully will work for you to to get a running WAS server in RSA):

1. Change Ubuntu’s /bin/sh to use bash instead of dash.
   In a terminal (sorry it’s the command line but you’re changing some system settings here that you would very very rarely have to do normally, or just if WAS didn’t specify bash specifically), run the following command and select the bash option as the default for /bin/sh:

   sudo dpkg-reconfigure dash

   (As pointed out by @oldmanuk (Dom Evans), this is the proper way to reconfigure where /bin/sh points to (though I used Gavin’s method). )

   After you’ve created your WAS profile and everything’s up and running nicely, run the command again to change back to using dash. The benefit of using dash is speedier boot time, which is lost if you leave the setting as bash (see https://wiki.ubuntu.com/DashAsBinSh – thanks Dom).

   Now you’ve sorted out the bash/dash problem. One down; two to go.

2. Check that you have a version of xulrunner installed (I have no idea what xulrunner is for but, looking in Synaptic Package Manager, my Ubuntu installation included xulrunner-1.9l.1-gnome-support, but not the xulrunner package itself, which seems to be fine for RSA purposes).
3. In your RSA installation, find the eclipse.ini file. I installed RSA to the default location so mine was in /opt/IBM/SDP. In a terminal change to that directory:
   

   cd /opt/IBM/SDP

4. Open the eclipse.ini file in a text editor, such as gedit:

   sudo gedit eclipse.ini

5. Add to the end of the file the following line:

   -Dorg.eclipse.swt.browser.XULRunnerPath=/usr/lib/xulrunner

   (From an Ubuntu forum post.)

   Now you’ve sorted out the ‘xulrunner’ problem and you can actually start RSA. Two down; one to go.

6. Start RSA from the Applications menu: Applications > IBM Software Delivery Platform > IBM Rational Software Architect for WebSphere 7.5.4.

7. RSA should suggest a directory in your home directory in which to put the RSA workspace. That’s fine; I just accepted the suggested location.

8. When RSA has opened (NB, my Welcome view doesn’t load – I don’t think that’s a problem), give it a moment to think, then it’ll pop up a wizard to create a WAS profile.

9. In the profile wizard, clear the option about security unless you know what you’re doing with WAS security and have a need to use it in a development environment.

10. You’ll also notice that there’s a warning about the currently selected location for creating the profile. This is the third problem I listed above. The default location shown is for creating the profile in the installation directory of RSA. Change the location to a directory in your home directory. For instance, I told it to use /home/laura/IBM/profiles.

11. When the wizard has created the profile (which will take a few moments – you can see the activity in the bottom-right of the RSA window), the default server for the profile is listed in the Servers view on the right-hand-side of the RSA window.
    The server is listed as ‘stopped’.

12. Right-click the server then click Profile. This opens a dialog box about the profile; I just accepted the defaults then it failed to start the server (the error said it had failed to start within 300 seconds). But when I repeated this step, the server started.

And that’s as far as I’ve got but it’s further than ever before. If I come across any more gotchas, or take some screenshots, I’ll update this post.

Yes, it is a pain to have to do all this but remember that WAS isn’t supported (as far as I know) on Ubuntu Karmic. If you want it easier, install it on something that is supported. If you want it on Ubuntu, I hope this post (and the others I cribbed information from) helps.

From the user’s perspective (who the software is written for, after all), they don’t want to know that the error was not expected by the people who wrote the code. The user wants to know that the software (especially when it’s important to their job/finances/life) is in control and knows *exactly* what’s going to happen when you press a certain button. The user has to be able to trust the software and trust that the developer(s) of that software knew what they were doing when they wrote it.

So it gets difficult for the developer/designer when they have to make a call that potentially risks breaking that trust. For instance, supposing you (as a developer) were to provide a new feature that is really beneficial to the target user but there is a small risk that something will go wrong in a big way for that user if they try to use that feature. As developer, what do you do?

Typically, I’d predict, you would make the feature optional so that you aren’t forcing the user to use a feature that could potentially (however unlikely) cause them serious problems. If the user does try to use the feature, you provide scary warnings of what could occur in certain circumstances. Hopefully, that will put them off unless they really know what they’re doing.

Okay, that’s the developer’s perspective. And it’s entirely understandable and even laudable that the developer is doing what they can to keep the user safe.

So, switch now to the user’s perspective. The target user is computer literate but had no knowledge of the development of this feature or who developed it. This user could benefit greatly from this new feature but when they attempt to use it, they get a scary warning message which, as intended, makes them think twice about whether to use the feature or not.

Now what does the user decide? Granted, risk is all about weighing up the costs and benefits, and to one person the relative benefit will outweigh the possible cost. To make a decision, however, a person needs as much information as they can possibly get. In this case, the only (and therefore critical) information is provided by the developer; that is, how informative and/or scary the warning message is.

If the developer provides a lot of information that makes the feature look useful, the user might just choose to use it. But if the developer makes the warning message as scary as possible, the user will probably opt not to use it.

The developer wants users to use the new feature because they’ve made the effort to develop it and it really could benefit many users. The developer, however, doesn’t (understandably) want the responsibility of trashing someone else’s laptop in some way. So the result is that the developer pushes that responsibility off on to the user, when in fact the developer has far more information available to help them make that decision than the user has.

If you’re the user, though, how are you supposed to make that call?

For example…

Computer Janitor is a utility that was introduced in Ubuntu Intrepid (I think) so that you could run it to clean up old kernels that are no longer needed, and other bits and pieces of packages that are no longer used. When I first tried to use it, I raised this bug, which, it turned out, had this duplicate.

Essentially, CJ could potentially remove packages that you might need. So when you try to use it tries to scare you into deciding whether you really really want to risk it. I raised the bug because the scary words don’t actually help you decide – in that, if you aren’t easily scared by such things, the scary message only determines how scared you are – not how well-informed you are to make a decision…and isn’t going to help when you break your computer.

What would maybe be more helpful is if CJ used a stricter set of criteria when selecting which files to remove. In this case, CJ might leave on your system  some files or packages that could be removed, instead of the reverse where it might incorrectly remove files or packages you need. The former is surely the preferably outcome for the majority of users (who would rather have a few unneeded files on their machine than a broken machine).

It would also be possible then, for the minority of users who really really know what they’re doing, to selectively delete the files that probably can be removed but CJ isn’t certain about. In this case, users are only presented with a decision to make if they actually seek it out but the majority of users are still able to benefit from the safer (if slightly less effective) behaviour. In fact, it would be better overall if CJ ran automatically during an Ubuntu upgrade so that the user really doesn’t have to care about it (unless they really really want to).

This is not intended as a dig at Computer Janitor as I think it’s a useful feature in general and I’m kindof surprised that this kind of clean-up wasn’t being done already whenever you do an upgrade of Ubuntu. Also, I think the bugs I’ve linked to above have caused a bit of a headache for the developers.

This issue of forcing users to make ill-informed decisions is a very common occurrence throughout software development and is certainly not specific to Ubuntu; it’s just that Ubuntu is a public development effort and provides examples that are relatively easy to explain. So please don’t be offended if you are part of the development teams for either Computer Janitor or Ubuntu!

So, if you, as developer/designer, find that you’re having to give scary messages to make a user *really* decide if they want to continue, consider stepping back from it, thinking about the possible decisions the user could make and what the consequences of those decisions are. Even talk to some of your target users and find out what decisions they’d make. Just because you can successfully scare them off doesn’t make it a successful feature – if the feature is potentially useful to the user, they should be able to safely use it (no matter what level of fear you instill in them). Then look at the bigger picture, think about it in a different way, and see if the decision can be made for the user, or the decision can even be removed altogether.

I’m sure that it’s not as easy as it might sound. And it’s not always easy to recognise situations like this. I’m hoping, though, that, having thought this through while writing this post, I’ll actually remember it in future the next time a similar issue occurs for me.

That’s on Saturday 24th October.

On Sunday 25th October (that’s the very next day!), you can roll out of bed and into OggCamp (if you’re staying at the LRL official hotel, the Connaught),.

OggCamp is brought to you by a joint collaboration of the Ubuntu UK Podcast and Linux Outlaws teams.

So come and join us for the last ever LugRadio Live followed by lots of barcamp fun!

OggCamp will happen in Wolverhampton on Sunday 25th October.

Why Wolverhampton? Well that’s where LugRadio Live 2009 (@lugradio) will happen too. On Saturday 24th October. See what we did?

So, the Ubuntu-UK Podcast (@uupc) and Linux Outlaws (@linuxoutlaws) podcast teams will be at LRL on the Saturday (and probably the Friday night as well) so we figured we may as well stick around on the Sunday too and organise an unconference where you can drop in to nurse your hangovers, see everyone again, and see some more talks, demos, or whatever.

As it’s an unconference, we won’t publish a full schedule beforehand (if you have an interesting presentation, just turn up on the day and if enough people are interested, you can give it) but both podcasts are likely to record some material during the day (one with swearing and one without ).

I will post more information as we know it. For instance, we should be able to announce the venue any day now…

I run Ubuntu Hardy on my Thinkpad T61p but (as I mentioned in a previous post) I use the proprietary NVIDIA graphics drivers so that I can have a decent resolution and use Desktop Effects. This works fine most of the time. Unfortunately, however, most times that I install updates that include kernel updates, the NVIDIA graphics modules become incompatible with the new kernel.

I guess that, were I running them, the Ubuntu graphics driver would be upgraded along with the kernel and this wouldn’t be a problem. As it is, though, after installing the kernel updates and rebooting, X (the graphics environment) takes some effort to load (on the computer’s part – not sure quite what it’s doing but it seems to be straining a little) before loading into a low, non-widescreen, resolution (bit like Windows safe mode). It also seems to revert to US keyboard settings so that certain non-alphnumeric keys are in the wrong place – awkward when entering a password that might contain them.

From there, I have to re-run EnvyNG (the nifty little app that goes away and installs the appropriate NVIDIA graphics drivers – or, in this case, probably just recompiles the modules or something), then reboot. And then everything’s fine. Today was about the third time this has happened. It’s not a major problem now that I know how to fix it but it is irritating and slow. The first time it happened it was quite concerning until I realised that running EnvyNG would fix it all.

So not very user-friendly. Better would be if the kernel update would recognise that there are other modules that are now incompatible (at this point you might be able to tell that I don’t really know how it works but that’s not the point) and, after installing but before rebooting, prompts the user that you’ll need to update them too (ideally with ‘and how to do that’).

VMWare have now cottoned on to this (yes, another proprietory app). Usually after a kernel update, you click VMWare Workstation to start and it just doesn’t do anything (again, rather concerning; if you know how to run it from the command line, you at least get a message that tells you to re-run the VMWare config script). Today, however, I got a little message pop-up saying that I needed to update the modules (or something like that) and I could press a button to do just that. It did it all for me and just worked.

So, some random praise for both EnvyNG and VMWare for making things easy to update. Minus points to Ubuntu Update Manager for not at least warning me that that would be necessary. I understand that by using proprietary software on Ubuntu, Ubuntu probably can’t (or shouldn’t) be held responsible for updating it, but it would be nice to be warned that I would need to run the updates myself.

Okay, not the most riveting blog post in the world but a start on my quest to have software developers (all developers; not just Ubuntu or even just open source) think a little and put in what might seem (to them) like niceties but which make all the difference to the user’s experience. Afterall, it’s for the user that this software exists at all.

Fortunately, while not a freedom-hater, I’m not averse to using proprietary drivers if I can’t make my laptop work any other way. And as this is my work machine, I need it to Just Work (or as close to as I can). So I installed EnvyNG (envyng-core, envyng-gtk) and ran that to install the proprietary NVIDIA graphics drivers. Incidentally, enabling the NVIDIA proprietary drivers listed in System > Administration > Hardware Drivers screwed up my graphics – I assume the drivers that Ubuntu thinks are right for my graphics card aren’t actually the right ones. EnvyNG, however, got it spot on–the widescreen display resolution (1920×1200) was automatically detected and worked straight off.

Ubuntu Desktop Effects (aka compiz)

This works pretty well. I had to look up how to enable, for example, the rotating cube (which is the ultimate desktop bling) which seemed to me to be a pretty bad Out of Box Experience (OoBE) – before installing Ubuntu on the Thinkpad, I’d booted once into Vista to check that the memory I’d installed was detected. In my brief visit, I noticed that things like the pretty semi-transparent sidebar and thought it’d be nice if Ubuntu did that without any effort on the user’s part (though, to be fair, someone else had installed Vista and, presumably, ensured it worked before shipping the Thinkpad – it would be possible to do the same for a pre-installed Ubuntu machine).

Rotating cube

My general opinion of the Desktop Effects is that while the effects themselves are amazing and a real step-up for Linux desktops, the Advanced Desktop Effects Manager, where you enable/disable the effects you want, is not incredibly easy to use. It’s often not clear what a given effect will do if you enable it. Nor is it clear what all the many many options for each effect will achieve. Really, we need a much simpler interface that has advanced options hidden away – something I’ll take a look at at some point…

The effects that I’ve enabled for now, and found useful/interesting/pointless-but-fun are:

By the way, Wobbly Windows are enabled by default. If you’re interested in knowing more about how Wobbly Windows came to be, here’s an interview with Red Hat’s Senior Interaction Designer (in 2005), Seth Nickell (PDF).

Enabling an external projector/monitor

Coming soon (as soon as I get round to taking some screenshots)…

I was privy to a pre-release airing last night and I was very impressed, having sat through hours of recording time on Saturday…

The show now has its own Twitter ID (@uupc) so that you can follow its progress from recording, through editing, to release.

Enjoy!
