Hi, it's just me.

Bang Your Drum

Just because:

Drones, Quadcopters, UAVs, Guns and Turtles

With Christmas rapidly approaching I expect quite a few drones/quadcopters/UAVs have been purchased (or will be purchased shortly) to be found under Christmas trees the next few days (depending on where you live).

At the same time there’s still a lot of scaremongering going on in the popular press about them bringing down planes and causing all kinds of other havoc. This has recently brought the FAA in the US to introduce mandatory registration for all drones heavier than half a pound (and heavy fines for failing to register a drone). To many this smells of overkill (pun intended) with some interesting reactions:

I’ll Register My Drone When You Have to Register Your Gun

Indeed, you can buy a gun (designed to kill things) without much hassle (and no registration) in many states in the US, but even a fairly small toy drone requires registration. Somehow doesn’t seem proportional.

Slightly tongue in cheek, but also with a serious background about how humans perceive risks, Popular Science titles:

Airplanes hit more turtles than drones – as of press time, no FAA calls for turtle a registry

From that article you might also want to follow the link to Could drones pose a threat to airplanes? for some more realistic thoughts about the risks (or rather largely lack of it).

Nevertheless, should you find a drone (or better a quadcopter or UAV, drone is frequently associated with the military type) under your Christmas tree I would urge you to not just take it out of the box, charge it and fly the same day. Instead, read up on it as much as you can. Study the manual. Learn about the weather. Think about getting insurance in case something goes wrong. Visit the forums of the manufacturer and read about the mistakes others made in order to avoid them (e.g. try the DJI Forums if it’s a Phantom or Inspire and read posts like TOP 10 common pilot errors). While I’m against the overregulation I think we’re beginning to see I’m also of the opinion they are not a toy and need to be handled with great care and responsibility. Think before you fly.

I’ve walked/driven over that bridge, now it’s gone

If you actually know a place in the news it makes it much more real than if it’s a place you’ve never even heard of. I’ve been to Pooley Bridge twice, among other things to go on an Ullswater Steamer cruise. While there I crossed the bridge giving the village its name a couple of times, both in the car and on foot.

Storm Desmond and the related rain has now destroyed the old bridge, built in 1764. Not to mention the flooding and misery it has brought to other parts of Cumbria. Carlisle (where I usually stay overnight on my journeys to Islay) has also been badly hit. I’m not sure of the exact area, but I believe one of the hotels where I sometimes stay is flooded as is the park where I go for my morning run.

As far as I know nobody has died and I hope it stays that way, at least people seem to be safe. Still, it will be a long hard slog for those impacted by the floods.

The Big Drum Off

What took them so long to get this organised?

The privacy risks of Big Data

Kind of a follow up to the It’s not a question of if, but only of when post from a few weeks ago. A fascinating but also scary read how it is possible to identify individuals from theoretically anonymised data:

Riding with the Stars: Passenger Privacy in the NYC Taxicab Dataset

Similar to this there is a lot of information in an itemised bill. Or a record of all websites visited…
