Exploring Psychology

Filed under: Open University,Ubuntu — Tags: , , , — Dougie @ 7:26 pm

The course material for DSE 212 just arrived. Once I’d got over the weight of the package, I opened it to discover that it consists of a number of large text books, a couple of DVD, CDs, software and the usual assorted paraphernalia - part threes, course updates and errata. Looking over the course material, it seems well structured and nicely presented. The study calendar would suggest that this is going to be intensive, with the first TMA due on the 11th November.

If you’re still reading – you might wonder what this has to do with Ubuntu. Well it comes down to the course software – a large part of the course is centred around the data mining software SPSS. Now of course you might well suggest free alternatives such as R or PSPP, indeed PSPP is intended as a replacement and is very similar. It’s not the same however and the big difference is that the course material is geared to step by step work in SPSS version 14.

The version is important, from what I can ascertain - SPSS version 17 is available for Linux. IBM has acquired the company so this may well continue. That said, version 14 is what has been supplied. This is not uncommon with the OU – MST121 for example uses Mathcad 2000.

Now, how about running in Wine you might say – the software has a little license validation applet that doesn’t seem to agree with Wine but I might be doing it wrong. However, for many studying is already expensive – why should it also involve complicating installation?

It has been suggested the Open University is not at all open to open source software. I don’t know if this is a policy or not but I do know that the Windows based software they supply is outdated. I can understand that this is probably for the same reason that Linux is not supported – that it would mean making substantial changes to the course material.

Course tutors I have spoken to have been extremely favourable to the idea of packaging software for Ubuntu and distributing it with course material. There are issues here, licensing and maintaining spring to mind – no to mention support. There is no way the OU Computing Helpdesk are going to support Ubuntu so that leaves the community.

Where does one draw the line between the desire to use open source software and the ease of using a provided solution? Am I putting myself at a disadvantage to my peers? Although I am confident with statistics, I’m effectively learning two systems as the course teaches one and I apply it to another system. Even if this entails five minutes an assessment, it’s five minutes that Windows users are excused. Moreover I’ve paid for it through course fees, can I get that refunded?

What surprises me is that the OU is about accessibility - anyone can study with them, except it would seem those who choose not to use Windows. Shouldn’t the Open University be Open?

What was your favourite comment in OpenWeek?

Filed under: Ubuntu — Tags: , , , , — Dougie @ 8:22 pm

I’ve been trying to get to as much of OpenWeek as I could and have really enjoyed a lot of the sessions. Dustin Kirkland’s session on encrypted home folders and of course the Docs Day sessions were fantastic ;-)

So I was wondering what everyone’s favourites so far were…

My favourite comment was from Mark Shuttleworth during his Q&A, I’ve seen similar questions asked so many times but I’ve never seen an answer as succint:

(12:24:03 PM) jcastro: <rabbit251> jcastro: QUESTION: Do you see Wine (and Windows-compatibilty in general)
or native Linux ports as the more important ingredient in the success of Ubuntu, or do they each play an
important role?
(12:24:18 PM) sabdfl: they both play an important role
(12:24:30 PM) sabdfl: but fundamentally, the free software ecosystem needs to thrive on its own rules
(12:24:41 PM) sabdfl: it is *different* to the proprietary software universe
(12:24:54 PM) sabdfl: we need to make a success of our own platform on our own terms
(12:25:08 PM) sabdfl: if Linux is just another way to run Windows apps, we can't win
(12:25:13 PM) sabdfl: OS/2 tried that

I’ve started using the last two lines as my email signature.

Add an XFCE menu to the Aspire One panel

Filed under: Computing — Tags: , , , — Dougie @ 3:51 pm

Acer have made some alterations to the xfce4-panel, you probably noticed that you can’t right click and add launchers.

Edit: For anyone who came here to find out how to enable the “advanced menu” or XFCE menu on right click – Open your documents, click “File->Terminal” and type “xfce-setting-show” or just “xfce-se” then hit tab. Click “Desktop->Behaviour” and then tick “Show desktop menu on right click”.

I have a workaround but haven’t worked out why yet. Open a terminal (from a Thunar window if you haven’t enable the right click on the desktop). Now if you look in .config/xfce4/panel there is your standard xml file to layout the panel. If you alter this, on relaunching the panel it overwrites it with the default.

The odd thing is that the un-patched panel is still there, and works as normal (look in /usr/bin – there are two panels, one renamed xfce4-panel.old). Well for some reason that I haven’t fathomed, if you kill the running panel then alter the config then run xfce4-panel.old then restart it the xml config is not overwritten.

Here’s a screenshot:

Reducing hard drive lifespan, follow up

Filed under: Uncategorized — Tags: , , — Dougie @ 2:42 pm

Following up on what I wrote yesterday concerning suggested damage to hard disks caused by Ubuntu not altering the number of load unload cycles set by the manufacturers, I noted that a number of people have been suggesting that Ubuntu should take control away from BIOS and carry out these modifications by default, as Windows does.

Well being the kind of person I am I thought I’d do a little investigation. Now after disabling the cycles from Ubuntu, I let the system run for fifteen minutes and noted that there was no increase where previously there had been.

Now I rebooted in Windows Vista Home Premium, let the system run for fifteen minutes and rebooted into Ubuntu. After taking measurements again, surprisingly there was a ten cycle increase.

So the only conclusion I can draw here is that Windows Vista does not alter settings provided from BIOS/microcode either.

Now as to whether or not increased time in the landing zone is detremental to hard disk lifespan is still very much open to interpretation, one thing is true though – the argument that Ubuntu is not doing something that Windows is doing is incorrect.
