Disruptor 2.0 – All Change Please

Martin recently announced version 2.0 of the Disruptor - basically there have been so many changes since we first open-sourced it that it's time to mark that officially. His post goes over all the changes, the aim of this article is to attempt to translate my previous blog posts into new-world-speak, since it's going to take a long time to re-write each of them all over again. Now I see the disadvantage of hand-drawing everything.

What I Did On My Holidays

And now, a post for my long-neglected, less technical readers.

I took a week off in July to try and avoid that Oh My God I Missed Summer Again feeling. Granted, it's easy to get that in the UK even if you're not stuck in an office the entire time.

Really this is just an excuse to post some photos on the blog.

Monday
Hopped on the bike and explored from Kensington to Westminster.

Felt distinctly smug when I grabbed my lunch from Victoria amongst all the less fortunate people who had to go back to their offices.

Tuesday
Decided to dose up on Culture, and went to the National Gallery.  Last time I was there I was eight years old, and I distinctly remember admiring the frames more than the art.

The rather marvellous Artfinder makes up for the fact that you can't take photos inside the gallery - I can share most of the pieces that struck me when I was there.

Wednesday
Finally got around to embarking on one of the walks in Secret London.  I chose to do the City, from St Paul's, covering Bank, Monument and Liverpool St.

It was fascinating. I've worked in a lot of places round there, socialise there regularly, and have explored a number of the nooks and crannies.  But I was astounded at how many places I had never seen, alleys I had no idea existed, and gardens hidden away between modern office blocks.

Highly recommended.

Thursday
My parents dropped by and I racked my brain for a different way to explore this massive, old city.  And it came to me: using the artery of the city - the river.  So we took a boat to Greenwich.

Where they were filming Batman.

And I didn't know until after we'd left.

Gutted.

Friday
The sun finally makes an appearance. I was going to write a blog post, but I refuse to be indoors on a sunny day if I can get outside for some Vitamin D production (and I hadn't bought my new shiny then).

Sat in the park, sunbathed.

Brilliant day.

Brilliant week.

Dissecting the Disruptor: Demystifying Memory Barriers

My recent slow-down in posting is because I've been trying to write a post explaining memory barriers and their applicability in the Disruptor. The problem is, no matter how much I read and no matter how many times I ask the ever-patient Martin and Mike questions trying to clarify some point, I just don't intuitively grasp the subject. I guess I don't have the deep background knowledge required to fully understand.

So, rather than make an idiot of myself trying to explain something I don't really get, I'm going to try and cover, at an abstract / massive-simplification level, what I do understand in the area. Martin has written a post going into memory barriers in some detail, so hopefully I can get away with skimming the subject.
