What I have been up to

July 24th, 2008

I have been deathly quiet on the Domino front recently, but don’t worry, I have been keeping myself occupied.

Some big news in the UK is that right now a major high street retailer is selling mini laptops, but not just any old mini laptop, this is the new webbook from Elonex (who you may remember I have met before). If you were to go right now to the home page of The Carphone Warehouse you will see a webbook. “nice, but unremarkable” I hear you say. Well that is just the start of the story. Right now on the web they are selling the Windows XP version, however in stores they are selling the much more exciting Ubuntu Linux version, yes you heard correctly Ubuntu Linux pre-installed. The pricing is pretty attractive too. They are giving them away free with a free mobile broadband dongle, but you pay a monthly contract price for bandwidth (the exact pricing will vary so I won’t quote figures here, go to your local store and ask them)

Now all this is really great news and well worth blogging about just as an exciting development in the mainstream adoption of Free and Open Source Software, but I haven’t yet told you what I have been up to. Well I took off my yellow hat for a bit and put on my red mortarboard of The Open Learning Centre and Alan Lord, myself, and some very clever chaps at Canonical and Warp have been working together to build all the software that goes on the webbook, including really great support for mobile broadband dongles.

There is quite a lot to say about the webbook, it is a lovely little computer, so much so that I have started a new blog dedicated to the webbook at webbookblog.com where I will be revealing tricks and hints to get the most out of the webbook.

If you ever considered getting a mobile broadband connection then this is a fantastic deal, get the dongle you want, use it on whatever laptop you have and get a free webbook (which also works with the dongle of course)

And another workspace . . .

April 8th, 2008

I have been messing about with CouchDB for a while. Back in 2006 I put together a couple of LotusScript wrapper classes for it using LS2J to do the communications and presenting a friendly API for putting Notes like data in and out of the CouchDB database. Now I have been mucking about with Python and PyGTK trying to build something of a GUI to link with CouchDB. Here are a couple of screenshots to give you a feel of the progress so far. Firstly the workspace, because every client worth having must have a workspace. This one is based on a gtkiconview widget. It really is getting the list of database names directly out of the CouchDB server. The icons are pulled from the filesystem at the moment but I want them to come from each database when I figure out how to work with attachments. They are .png files, I think .svg would work too, along with most other formats you could mention.

This next screenshot shows a form. The form is designed using Glade, a user interface designer which saves UI definitions as XML. The client code reads the XML and inserts the form into a new tab in it’s own user interface. At the moment the form XML is being read from the filesystem, but that too can come from a document in couchDB.

This will probably run on Windows as well as Linux. I don’t think GTK (or the Twisted/Python/GTK collection) runs on Mac at the moment.

Document Freedom day

March 26th, 2008

Happy Document Freedom day!

Today would be a great day to install OpenOffice.org or Lotus Symphony if you haven’t already. If you already use these great tools then today would be a great day to show them to someone else.

The Open Document Format is a well designed modern format which any system creating documents for use in a wordprocessor, spreadsheet or presentation tool can use. Over the last decade or so the free market in office suites has basically been destroyed by the Microsoft monopoly. This happened not because Microsoft were producing better software, the users of Smartsuite, Wordperfect etc. were really quite happy with their software. It happened because Microsoft got themselves into a position where the format of choice for exchanging documents was .doc and .xls and .ppt. It became the defacto standard. The other products reverse engineered this binary format so they could support this defacto standard, but people discovered that the best way to reliably interchange the Microsoft owned format was to use Microsoft software. Not much of a surprise there really. Microsoft won a lot of business by ensuring a lack of a level playing field.

Open Document Format or ODF is an XML based file format which is designed not to just be the format used by one application but by all of them. Microsoft could support ODF as a native file format for Microsoft Office if they wanted to. It is not a software engineering challenge that they can’t rise to. They don’t want to because it would end their convenient distorted marketplace. Moving to ODF as the normal way of interchanging documents between businesses in future will level the playing field and re-enable a free market and free choice of software applications.

The Microsoft binary formats are at the end of their life. Now is the time to choose which direction to go forward. Microsoft want us to use their OOXML format. They desperately want to protect their position and revenue stream, which is understandable,but not my problem.

Document Freedom is in your interest, tell someone about it today.

Almost a workspace

March 9th, 2008

As many of you know, I have been playing with various small Linux based laptops which are going to change the world. One thing I have noticed on some of them is a familiar user interface. This is the Elonex One, it was launched last week in the UK and I was there to play with it, I even did a review. Here is the home screen of the One in tablet mode:

Elonex One

Now lets look at another small Linux laptop, this is the Asus EeePC which in the UK RM are calling the RM Minibook:

EeePC

Does that remind you of anything? Let me give you a clue :-)

Notes on EeePC

I couldn’t get Notes standard for Linux running on it (mainly because of the odd way IBM packaged the install I think) but this is Notes 8 basic for Windows running under Wine.

Of course no article about world changing Linux laptops would be complete without a picture of the One Laptop Per Child XO laptop so here it is:

No workspace on that one, but it is running CouchDB (yes, that URL does start with localhost)

dis29500.org has gone a bit Dojo

February 5th, 2008

I have been updating dis29500.org importing lots of new data in the form of the leaked dispositions and adding a new system for tagging and some Dojo prettyness. Have a play and let me know if anything breaks. Feel free to blog about it too, there will be a bit of a relaunch in the next few days, but it would be nice if the lotus blogosphere got the scoop on it.

The OLPC XO, 30,000 teachers and me

January 22nd, 2008

My followup article on the visit to BETT has now been posted on the OLPC news website I know it is somewhat off topic for my regular Dominux readers, but the BETT show was pretty amazing. You might be at Lotusphere right now with an estimated 8 kilogeeks, but BETT draws in 30 kiloteachers from all over the world. In the picture on the right I am the one who would need some glue and cotton wool if I was wearing a santa suit.

Day 1 of not being at Lotusphere

January 21st, 2008

Well day 3 or so if you count all the days I would have been there if I was. Today is the Opening General Session which I am following live as the expected announcements flood in. So why am I here and not there? Basically when the call for abstracts went out I figured I had nothing much to say this year. Last year was great showing OpenOffice.org integrating with Notes. This year the Productivity Editors AKA Symphony is more of a reality, but I am not that interested in them. I am focusing more and more on work under The Open Learning Centre brand rather than Dominux and I couldn’t really justify the cost. So this year I will spend a week in January wishing I was elsewhere, but on the other hand I will eat in February.

Well I have had an amazing day today!

January 10th, 2008

Back in December The Open Learning Centre (which is myself and Alan Lord - The Open Sourcerer ) was invited to meet up with The Open Forum Europe to discuss ways we could work together. They invited us to go to the BETT show and help out on their stand talking about Open Source software. I said I would bring along my OLPC laptop as an example of Open Source in education.

Come last week, my laptop had not arrived. We had nothing to show, not much to say. HELP!! We needed a new plan. I borrowed a bit of space on the olpcnews.com website to appeal for anyone with an OLPC to let us borrow it for BETT. A couple of days later we got a call from Tomi Davis, the chief executive of OLPC Nigeria who lives in North London offering some laptops. Yesterday we went to see him and he lent us three of the most excellent OLPC XO laptops. We had a good play with them whilst munching meatballs in the IKEA restaurant then we were ready. Today was manic. The OLPC laptop was on BBC breakfast news this morning. We had loads of people come up and tell us they had just seen the laptop on the TV. One teacher told us that just seeing the laptop made his vist to BETT worth the effort. Tomi joined us for the afternoon and we were interviewed on camera by the show TV crew. We made loads of interesting contacts in the UK and abroad, everyone wants these laptops and they want Open Source software in their schools. Today BECTA (nice bunch of folk, they liked the laptops too) released a report on Microsoft Vista and Office 2007 I think their conclusions are just as appropriate for business as for schools.

So today we have been demoing someone else’s laptops on someone else’s stand which we got at the last minute through an appeal on someone else’s website and they are all really really happy that we did it!

Google Charts with Formula language

December 7th, 2007

Google just released a new toy for us to play with, the Google Charts API. It really is very simple, just construct a URL in a particular way and it gives you a png file.

Lets say for example you have 12 months of sales figures in millions of pounds as below (these are not the actual Dominux sales figures)

sales:=12:15:16:18:25:30:28:42:32:35:36;

then you need to encode this by replacing the numbers with letters where A=0, B=1 etc.

valuecodes:="ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789";
coded:=@Implode(@Transform(sales;"v";@Middle(valuecodes;v;1));"");

and now generate a url and put it in an img tag
"<img src=\"http://chart.apis.google.com/chart?cht=lc&chs=200x125&chd=s:"+coded+"\">"

so shove all that into some computed text and make it passthru html to get

The Slashdot effect

December 4th, 2007
dis29500.org was on the front page of Slashdot this morning at 6am. Initially the site could not cope, but then it was running as a virtual machine with 128MB ram and hosting dis29500.org, A Story For Bedtime, The Open Learning Centre, The Open Sourcerer, Fondoo.net plus routing email and running couchDB and running the Red5 flash streaming server. It now has 450MB or ram and it is very responsive. It would have been nice to see a Domino server slashdotted, and I certainly could have written dis29500.org in Domino, I am just more interested in doing interesting things with technology that I don’t know like the back of my hand.
