Firefox 3 seems to have fixed memory problems

Filed under: personal, web development — alan @ 10:22 am

I had been reluctantly considering giving up using Firefox as it crawled to a halt so often on so many sites. To be fair I think it is because I keep lots of tabs open and Firefox did not seem to deal will with pages with many refreshing elements … many air and train ticketing sites were particular problems. However, Firefox 3 has been running continuously for some time now and looking at ‘top’ in terminal window has about 1/3 the real memory footprint compared with Firefox 2 … now it is comparable with Word, Dreamweaver, etc. … I had been sticking with Firefox largely because the Firefox Snip!t bookmarklet works better than the Safari one, so now I can continue to do so without the machine crawling to a halt - well done team Mozilla :-)

escape from distraction

Filed under: HCI and usability, Uncategorized, academic, personal — alan @ 8:27 am

Last week I was away in Cornwall and lost (but later found) my phone, so was both without a phone and with no internet connection … and it was amazingly liberating. My life is driven by the never ending stream of incoming mails and while in principle I could ignore them, in fact I find myself constantly breaking off what I do and seeing what has come in.

This reminded me of a Times article Haliyana pointed out to be a couple of weeks ago “Stoooopid …. why the Google generation isn’t as smart as it thinks“. We make a virtue of the never ending stream of interruptions that assail us; “multi-tasking” we call it, but in fact they not only mean we are less focused, but are possibly loosing the ability to concentrate at all.

While reading the article itself I found myself fighting not to want to follow the numerous links to other stories that littered the Times online page … and I would like to tell you more about it, but I never managed to read to the end before succumbing to the next interruption.

Basic Numeracy

Filed under: Uncategorized, academic, personal, political — alan @ 1:09 pm

When the delayed SATS results eventually arrive, I’m sure there will be the regular navel gazing at the state of basic numeracy and literacy in UK schools. But what about those who were in primary schools 30 years ago?

This morning on BBC News Channel an interviewer was talking to an economist from the City. They were discussing the reduction in bank lending (a fall of 3% during June, with 32% year-on-year drop ) and its implications for the housing market and the economy in general. The interviewer asked if it was accelerating and the economist agreed, mentioning how the year-on-year drop had gone from 10% in one quarter to 20% in the next and now over 30%.

Of course these figures are all based on a year-on-year average that includes the period before the credit crunch began last autumn and in fact are consistent with a steady linear fall of around 3% per month for the 9 months since the Northern Rock collapse. That is an alarming rate of fall, but not evidence of an accelerating fall.

This apparent lack of basic numeracy reminds me of a discussion some years ago with senior financial executives who dismissed any attempt to quantify projected company income as ‘just numbers’. Having lost money in the Northern Rock collapse I wonder whether the executives in Northern Rock and other banks had a similar attitude!

I know it is easy for me as a trained mathematician to hold up my hands in horror, but still these are people who are playing not only with their own livelihoods, but also the lives of their investors, ordinary people and even the state of the entire economy.

We do have a peculiar attitude in the UK where it is acceptable for highly educated people (including many computer scientists) to just ‘not do math’, and furthermore say so with a level of pride, whereas to say the same about reading would be unconscionable. Other European countries seem far more numerate, so this seems to be a cultural phenomena not an intellectual problem.

I have heard that one of the best predictors of educational success is if a child is willing to put off a treat for another day. Mathematics does require doing work at one stage to see benefit maybe many years later, but this to some extent runs counter to the increasingly common expectation of students to want to know fully and completely how something is useful to them now.

Maybe the answer is for schools to have lessons in leaving sweeties until tomorrow … and perhaps remedial lessons for City economists who matured during the Thatcher years.

Thusly, he wrote

Filed under: Uncategorized, academic, personal — alan @ 9:10 am

Was with Kiel, one of my PhD students the other day, reading a draft chapter of his PhD thesis. He used the word ‘thusly’ and at first I thought this was a Kiel-ism (sorry Kiel, you do have a few). However, he assured me it was common usage … and not just for him. I suspected it was a regional idiom and indeed a bit of web searching finds many archaic uses of thusly, but several more recent Lancashire uses.

I suspect the word arose because ‘thus’ often precedes a verb and so has acquired an adverb ‘-ly’ ending … a form of lexical over-generalisation. … and if you have not already stopped reading because you can’t understand why anyone would be even interested in this level of language … as I did the web search found a lovely discussion site called INTERACTION (and no, this one is not the synonymous BCS HCI Group) where one person mildly mocked another for using ‘thusly’ in the 21st Century … obviously not a Lancashire lad.

This has also made me reflect on my own frequent use of ‘thus’ to mean ‘therefore’ as opposed to ‘in this way’ … argh am I really a grammar nerd :-/

wall building - is this ordinary life?

Filed under: personal — alan @ 6:14 am

On Saturday I ‘only’ did 2 or 3 hours work, on Sunday ‘only’ about 8 hours and yesterday, Monday, ‘only’ 8 hours … and spent the rest of the time wall building in the garden :-)  With that and two evenings last week when I had left the office ‘early’ at 7pm, I have about 20 foot of wall over 18 inches high.  The wall is built of small stones scavenged from the soil as I dug and moved it about over the last few years (there is a lot of stones in our garden!), so actually a lot of work behind 30 square feet of wall.

I have got so used to 24/7 working that I have entirely forgotten what it is like to simply take a little time not at the computer, reading papers to review, or in meetings.  After 3 days of what would end up being ‘only’ a 50 hour week it feels like I’ve been on holiday for ever!

What has happened to academia that the opposite has become ‘normal’?

pantoum amongst the lost emails

Filed under: books, personal — alan @ 6:42 am

About to go off to Edinburgh for 2 day meeting of the Branded Meeting Places project in

Doing quick check on my outbox for 1/2 written emails that I need to finish … and then found the following from July 2006

spring flowers in the meadow
gold sunshine glinting
the grass between lies
cool and smooth

gold sunshine glinting
across the rippling waters
cool and smooth
towards the lonely isle

across the rippling waters
birds fly gently
towards the lonely isle
majestic but desolate

birds fly gently
spring long past
majestic but desolate
the snow buried grass

The Making of a PoemI recall the context now. I has been reading “The Making of a Poem” a lovely book, that discusses different poetic forms both history and current use and with loads of examples of each, classic and modern. I was talking to Masitah about the pantoum, a Malay poetic form where the 2nd and 4th line of each verse become the 1st and 3rd line of the next verse. I constructed the above as an example as we chatted! I had typed it into an email to save it and there it has lain, forgotten, ever since.

I think traditional pantoums have a particular rhythm structure within each verse, so my attempt above has the right line structure structure, but not the right metre. However, I did like the way it created an apparent continuity, yet the meaning could shift underneath - in this case from spring to winter.

My favourite in the book was a modern pantoum by J. M. McClatchy. He repeats the sound of the lines … but not necessarily the words … so in the first verse, the second line is “Seem to pee more often, eat” and in the beginning of the second verse this becomes “Sympathy, more often than not“. Or in the middle “The hearth’s easy, embered expense” becomes “The heart’s lazy: remembrance spent“.

Now back to looking for those urgent mails before the train!

one man went to mow

Filed under: personal — alan @ 7:35 pm

In the long winter months, when nothing grows, I forget how much I hate mowing the grass.

They say wood warms you twice, once when you chop it and once when you burn it. I suppose grass is a bit like that; it breaks your back once when you mow it and once when you rake the cut grass. But the mowing is worst - an hour bent double, this must be how it felt rowing a Roman galley. Surely it is not beyond the wit of modern science to develop a mower that cuts grass when the handle is held more than 18 inches off the ground?

If I were an ancient Greek and cursed in Hades for offending Zeus, or a Catholic looking forward to 100 years in purgatory for my sins, surely this would be my fate: to mow the Elysian Fields while the Demi-Gods play.

Broken Soldiers, Tibetan Monks, and the Love of God

Filed under: personal, political — alan @ 11:56 am

A few weeks ago Nad took part in a fund raising event for injured forces; on the television this week I watched “Battle for Haditha” recreating the events leading to a massacre of Iraqi civilians by US Marines and “The Passion” recreating the events leading to the first Easter and the crucifixion of Jesus; and in the news are the reflections of 5 years of bloodshed, occupation, freedom, and fledgling velocity (choose your own words) in Iraq and of rioting in Tibet.

Look around you, can you see
times are troubled, people grieve
see the violence, feel the hardness
all my people, weep with me

Kyrie Eleison, Jody Page Clark

pulling a plane for charityNad maintains the website for ForcesHospitalCharity.org, which was set up by the emergency services at Birmingham Airport in response to seeing the injured soldiers brought back from Afghanistan and Iraq. The charity does not in any way support the forces in the field, or politically support the conflicts themselves, but is purely about humanitarian aid for those people who have returned, often with severe injuries, and for their families. However, despite this Nad has been criticised by those who ask “question why (he), a Muslim, (has) chosen to support a charity that attempts to aid the very soldiers that are killing our brothers and sisters abroad.” (see Nad’s blog entry).

In the “Battle for Haditha” both US Marine’s and Iraqi ‘insurgents’ were shown as people who in different ways cared and protected their own. It is natural and human to care for those close to us, who share ties of family, nationality, race or religion. Those closest to us, our children, parents, friends, have first place in our affections and often a special call on us. This human love is a good thing. But is not the end of things.

I was disappointed that the Dalai Lama, whilst outspoken against Chinese actions against Tibetan rioters, was relatively muted in addressing Tibetans themselves. The riots there began with Tibetan crowds attacking ethnic Han Chinese and even Muslim Hui1. The targets here were not police stations and public buildings, but shops, homes and ordinary people. It seems the Chinese held back for fear of international sentiment while ordinary people were killed or made homeless. Then when the Chinese security forces were unleashed they struck hard … hitting back at those who had hurt their own.

Dalai LamaIn the Dalai Lama’s press release he says that “a form of cultural genocide has taken place in Tibet”, “the Chinese government discriminates against these minority nationalities”, and in their response to the situation the authorities “believe that further repressive measures” are the way forward - this is I am sure all true. However, in contrast, about the rioters themselves, the Dali Lama merely says “the demonstrations and protests taking place in Tibet are a spontaneous outburst of public resentment built up by years of repression”.

Why is it so hard for him to denounce the ethnic attacks of Tibetans themselves as well as the repression of the Chinese authorities? But I know I am the same, overlooking the understandable failings of those close to me or those I support, whilst feeling righteous anger over the way they, the other, treat my own kind.

The Dalai Lama shows a deep, and human love for those he is responsible for.

In Gethsemane, one of Jesus’ friends, tries to defend him when temple guards come to arrest him2. The unnamed disciple (I always assume Peter), strikes with his sword and cuts off the ear of the High Priest’s slave. Jesus admonishes his followers and heals the slave. On other occasions Jesus talks with, shares food with or heals Jewish Priests, Roman Centurians, lepers and prostitutes - friends and enemies, the unclean and the immoral,

In a recent blog “A Charter for Compassion“, Nad discusses a TedTalk by Karen Armstrong on the Golden Rule. This comes in many forms, some more about harm “Hurt no one so that no one may hurt you”, some about behaviour “do unto others as you would have them do unto you”3. Most personal is the form from Leviticus “Love your neighbour as yourself”.

But who is my neighbour? My family, friends, the Welsh (maybe even the English), people I work with, the person next door, in this Internet age perhaps FaceBook friends, or people who add my photos as Flickr favourites? Jesus is asked this and in response tells the story of the “Good Samaritan”. In school I recall we wrote variants of this where the Jew and the Samaritan were replaced by rival football teams, or Catholics and Protestants in Northern Ireland. This story of the Samaritan caring for someone who would have despised and persecuted him goes beyond human love, it is the love of God.

If the story were told today who more likely that an injured British soldier and young Muslim man.

Those who criticise Nad, show that very human love, just like the Dali Lama, just like I see so often in myself - caring for those close to us, “our brothers and sisters” in race, religion or political beliefs. In working beyond that, Nad shows no less than the Love of God.

Beyond Reason

Filed under: books, personal — alan @ 11:08 pm

I thought I had stumbled across the web site of an obscure religious cult or maybe just an extreme evangelical sect.

The signs were there. First the changing banner at the top showing images of The LEADER, sometimes looking meaningfully into the distance, sometimes preaching to his devoted disciples, and sometimes staring you directly in the eye convicting you of … you don’t know what but something. Then there was the sidebar densely packed with adverts for books (mostly by The LEADER) including the quotation from the review (by someone you had never heard of) telling you this book would “change the world”. Not to forget the devotional DVDs featuring The LEADER as narrator, or of him talking with others Of Like Mind … a sure sign of these fundamentalist sites when they only discuss with those Of Like Mind.

You need never be fooled, the signs are always obvious - even the address the “Upper Branch” office in California (I assume novitiates start on the Lower Branch) and the inevitable link to a ‘Foundation’ in this case a Foundation for “Reason and Science” - definite shades of Mary Baker Eddy!

The comments at the ends of articles were a little more unusual - it is only the most open cults (or the most confident in their brainwashing) that allow their members voices - but these were not exactly what I expected certainly unmeasured, but with a tone somewhere between MySpace and British National Party … definitely Mid-West Millenialist. About 1 in 7 were even odder with some words I couldn’t make sense of (a form of net-speak?) and even when the words were English the order seemed random and virtually grammarless .. of course, glossolalia … Pentecostal influences. … but most unsettling of all were the images chosen by the contributors as their icons, some I could not even recognise and wonderd if were even legal,

and the site? … RichardDawkins.net (and I feel I ought to pronounce the name in hushed tones), the self professed “clear thinking oasis” … well no false modesty here.

Amongst the top level tabs on the pages are the ‘Store’ (what else) ‘Donate to RDF’ (the Richard Dawkins Foundation silly, not the semantic web notation!) and ‘Science’ and ‘Reason’. Under ‘Science’, we see everything from Archaeology to Psychiatry, Economics and Law .. yes he really is omniscient. Under ‘Reason’ we find less entries: ‘News’, an FAQ and … out of only five content categories … “Religion as Child Abuse” … note not even “Religion and Child Abuse” but “Religion as Child Abuse”. It is good to know that ‘Reason’ has such a staunch defender.

cover image: when they severed earth form skyRecently I have been reading “When They Severed Earth From Sky“. The authors, Barber and Barber, describe recurrent patterns in myths across the world - not in a Jungian sense of archetypes, but because we all share a common human nature and cognitive make-up (they subtitle the book “How the Human Mind Shapes Myth”). They mention (p.93) the frequent myth of cannibalism ascribed to one’s enemies citing Arens’ “The Man Eating Myth“, in particular are accusations of abuse against children: the Romans accused the early Christians of infanticide and the Medieaval Christians did the same to the Jews. … it seems Myths die hard and ‘Reason’ can always be helped by a bit of mud slinging.

As an academic I am a little taken aback that a fellow academic would lend his name (or should I say His Name) to a site like this, but I guess every wandering preacher needs to earn a buck … and anyway he is an Oxford professor and I was a Cambridge man so never did trust the other place.

More seriously, for some time I have had a half-written entry about the religious issues of evolution. I use evolutionary arguments frequently in my work, but wish to distance myself from the pseudo-religious evolutionists … maybe soon I’ll finish it.

Significantly (yes this is one of those confession moments), after all my life being a solid Darwinist, there was a period in my mid-twenties when I doubted Evolution (brothers pray for me) … and it was exactly writing like this that made me doubt. If the arguments for evolution were made in this way and those who supported it were so unreasoned, could one trust it at all.

Although mentioning Genesis will I am sure instantly condemn me, I was reminded while looking at this site of the tower of Babel and the people who thought that if they built enough of an edifice they would become like God.

chimpThe one redeeming feature on the Dawkins’ site is that amongst the many images of him gazing into the distance, or preaching to the converted is one of a chimpanzee. If you can at least see the funny side of yourself there is some hope.
