A large crater to dump my thoughts

Childhoods’s End by Arthur C. Clarke

This book explores two interesting but related ideas: that humanity hasn’t finished evolving, both physically (genes) and in terms of behaviour (memes). What would happen if there was no more hunger, no more war? This novel was interesting but mostly for the underlying ideas; the story or characters weren’t particularly vivid.

Of men and mice by John Steinbeck

Enjoyable and memorable book, which seemed more like a short story.

I read this on a train journey through the English countryside from London to Norwich. The result is that now I can’t help but imagine Lennie and George strolling across some sort of cross between the green, wet, English fields and the south Californian plains.

Snuff by Terry Pratchett

This was an enjoyable read, like most of the Discworld novels, but not one of Pratchett’s best. Pratchett’s take on prejudice in two ways: Pride and Prejudice, and prejudice about other species (goblins in this case).

Do Androids Dream of Electric Sheep? by Philip K. Dick

Another Sci-Fi classic, and rightfully so. Does empathy really set humans apart from Androids?

Roads

with one comment

My road calls me,
Lures me west, east, south and north.
Most roads lead men homewards,
mine leads me forth.

Thin Air and Goose Bumps

This was a truly wonderful concert. What’s better than sipping herbal tea in an old church, seeing Anathema in concert for the first time? I still get goose bumps on my back just watching the recording.

It’s getting cloudy now

leave a comment »

Cloud computing is all the rage these days. It is, in short, computing as a service instead of as a product. This has serious advantages but also has a negative side that may not immediately be obvious.

The concept is pretty simple; somebody keeps some physical computers up and running and provides computing time on those computers to others, rather than everybody buying their own hardware. Sometimes this service is provided by a different part of the same company or government (a private cloud) and sometimes it is sold as a service (a public cloud, like Amazon EC2).

From the perspective of deployment and resource management, the cloud is a great idea. It’s easy to go from nowhere to having a couple of hundred machines running. No need to buy more hardware, fiddle with install CD’s, or worry about replacing broken parts. Everything can be done without having to leave your desk. And it’s possible to scale an application as demand requires; adding a few more servers can be done in less than a minute, and getting rid of them is probably just as fast. It’s easier to get redundancy. Quick repurposing of machines when demand requires it. Anyway, great stuff: the engineer in me is thrilled.

But it’s not all rosy. Cloud computing is just a technology, and technology isn’t inherently good or bad – it’s how you use it. There are plenty of valid use cases for the cloud, but it also enables some worrying behavior.

For starters, it makes it possible for companies and governments to outsource the physical machines and lower software layers they run their applications on. This means that (private) user data gets shipped around to not just one external party – the one running the application – but also to the cloud provider or providers that are providing the hardware it runs on. Their security or downtime can affect a large number of customers (and their customers). The cloud providers may be in a different jurisdiction (or often, multiple jurisdictions) with different legal systems, opening their customers up to legal issues regarding data retention or foreign government surveillance. And while having data spread across different companies and different continents was not impossible before the cloud, it certainly has become a lot easier and more common.

Handing over control over my personal data to so many companies (and governments) makes me uncomfortable, but it’s so darn convenient. Is there no way we can have the best of both worlds, some sort of hybrid model?
