Keep on rollin’

Attracted by algorithms some while back, I bought myself this audiobook… it sounded like exactly what I was looking for:

I found it hard going if I’m honest. Listening at 1.25x speed helped.

But while the ‘optimisation problems’ of public parking turned out to be vaguely useful at work, my heart sank a bit the other Saturday when rolling the ‘relevant complexity’ dice served up the answer: ‘Audiobook’…

…Ho hum. But you have to trust the dice.

And sure enough ‘Algorithms to live by’ proved the point; the chapter on ‘Randomness’ validates a lot of what I’ve been trying recently:

Recent work in computer science has shown that there are cases where randomized algorithms can produce good approximate answers to difficult questions faster than all known deterministic algorithms.

One problem they help with is ‘Hill climbing’ and local maxima.

At any point in life – however much you’ve perfected it, the risk is it could still be better. Like a climber in the mist, you know you’re in a good place – but there might be an even better one you can’t see for the fog.

And randomness is the way to find out.

Try something a bit different and you can find out whether you’re at the top of a small hill of possibilities – or surveying the entire range from the highest vantage point.

The truth of life is: you never can know if you’re stuck in a local maximum. But the odd throw of the dice now has the full weight of computer science behind it!

Keep on rollin!

Mere Civility

sɪˈvɪlɪti [noun] – formal politeness and courtesy in behaviour or speech: “I hope we can treat each other with civility and respect.” Courtesy, courteousness, politeness, mannerliness, graciousness, consideration, respect, urbanity, cordiality.

It’s autumn; the clocks have gone back and the nights are getting dark…. So it’s time to start rolling the ‘relevant complexity’ dice again – for audio accompaniment to cooking, cleaning up the kitchen and stacking the dishwasher.

On Tuesday the dice said listen to a Philosophy Bites podcast

So I did; and listened to a fascinating one with Teresa M. Bejan from Oxford University on the topic of civility:

It’s here

Looking for more, I found her book ‘Mere Civility: Disagreement and the Limits of Toleration’

As the synopsis rightly says:

Today, politicians and intellectuals warn that we face a crisis of civility and a veritable war of words polluting our public sphere.

In liberal democracies committed to tolerating diversity as well as active, often heated disagreement, the loss of this conversational virtue appears critical.

But is civility really a virtue? Or is it, as critics claim, a covert demand for conformity that silences dissent?

This is exactly what I was talking about with a former colleague of mine, in a lovely walk in the autumn sunshine past the ‘Mother of Parliaments’ yesterday.

Surely the disfiguring scaffolding all over it, is a reminder of how much democracy and civility need bracing in this country – and many others – right now.

Back to ‘Mere Civility’… it turns out that:

Many of the pressing questions facing liberal democracies today – what the proper scope of liberty should be and how to handle partisanship and hate speech – closely recall early modern concerns about the limits of toleration and the dangers posed by sectarianism, evangelical expression, and so-called “persecution of the tongue.”

Then as a now, thinkers appealed to civility as a way to reconcile the tension between diversity and disagreement, but determining what civility requires can be complicated.  While some restraint on expression is surely necessary to make disagreement tolerable, accusations of “incivility” can easily become pretexts for persecution.

The issue with civility is it feels weak and insipid, if it appears to allow bad things to be said. But when institutions close ‘protest’ down, there’s an equal fear that ‘free speech’, the legitimate right to be angry and to demand change is being curtailed.

I’ve spent significant parts of the last few weeks – at my university – writing new policies and procedures which walk this tightrope.

In work, in politics and at home, I’m an advocate for civility – if you’re not even prepared to listen there’s not much hope of reasonable accommodation or collective progress.

But the suffragettes weren’t civil, Malcolm X wasn’t civil and some of the protesters we host at work aren’t either; but the things they were and are fighting for are good things.

Theresa Bejan argues for ‘mere civility‘ – the absolute bare minimum of it:

that allows for rude, rambunctious, honest debate without the disputants attempting to eject each other from society, 

That’s the baseline I’m defending at work; but I must say I’d like to see a bit more civility than we have.

As a middle-aged, middle-class white ‘family man’ that’s easy to say – all society’s norms are tuned to me. If I was a woman, black, gay or poor I might see things very differently.

Perhaps ‘mere civility’ is right – we shouldn’t seek to be too comfortable in a world full of inequality.

Happy Tracks II

Has anyone else in the entire world got a playlist with Tom Jones, Vic Reeves, The Bee Gees, Bass-O-Matic and The Skids in it?

I’d be surprised.

But that’s the joy of Spotify – it learns what you like.

Every Monday the ‘Discover Weekly’ playlist serves up more songs like the ones I’ve ‘liked’ before, and the number and variety of my ‘Happy Tracks’ just gets bigger and bigger.

It has become a standing joke in the car with the kids; my Happy Tracks are frequently unlistenable to younger ears. But they get me toe tapping and steering wheel slapping.

Of course there must be a natural limit – I’m up to 504 songs now in less than a year – and growing steadily. Plus we know that learning algorithms drive ads, monetisation and ‘fake news’.

My original Happy Tracks were assembled by me – now a computer does it. That can’t be all good.

But sometimes you just have to know when you’re beat. Months ago I bought a book on computer science and algorithms to see if I could do exactly this: train an algorithm to serve up my taste in music, art and writing… And then I realised that’s exactly what search engines and social media firms are doing… doh!

Still you can’t be too happy. And Happy Tracks simply puts me in a better mood every time I put my headphones on.

So here’s to artificial intelligence – and stupidity – because Spotify is smart enough to come up with enough duds to kid me I still have superior taste!

Cookin’ up a storm!

The first autumnal day of the year – rain tippling down. What to do..?

Showtime!

A fridge and freezer full of forgotten and forlorn ingredients; and no major jobs or responsibilities to see to…

The result?

    A mighty fine ham n cheese omelette for breakfast
    Spicy mustard seed prawns for lunch
    Aubergine curry in the fridge for tomorrow’s lunch
    A half decent Bolognaise on the table for the family
    And a failed Indian cooled carrot salad in the bin… still, learned from my mistake!

Happy days – I haven’t had a day in the kitchen since we moved house.

There’s no better way to spend a rainy Sunday than cookin’ up a storm!

Avoiding behaviour

Time to own up…

I’m in denial.

I really don’t like the idea of turning 50; even though I’ve convinced myself it’s only the attention I don’t fancy.

I’m a better man than I was turning 40; more skilled, knowledgeable, kinder and more resilient and optimistic. But my job and professional life are much worse.

Still, if there’s one thing I’ve learned these last few years, it’s this: positivity and action beat carping and ruminating.

The universe is on your side if you keep fighting the good fight.

It’s all good – once next week’s out of the way…
