The Anti-Gun Lesson from Pistorius

So it looks like he’s out on bail.

He could be guilty of murder, or he could have been trying to protect his home from burglars.

Let us assume it’s the later. There are all sorts of problems with his story of what happened – if you were to tackle a burglar in your own home in the middle of the day with plenty of practice at that sort of situation.

But in the middle of the night ? Woken from a sleep and still in a daze? And not really knowing what to do ? It’s all to easy to imagine me doing something really daft in that situation is all too believable.

Add guns to that mixture, and you have the recipe for a disaster. Which if Pistorius is telling the truth is exactly what has happened.

There are those who argue that it is a right to keep a gun in the house to protect yourself from burglars. Ignoring whether it’s a right or not, it is for most of us a dumb thing to do. Most of us do not undergo the sort of training that will let us make sensible decisions in such a situation, and those that do have the training are not likely to operate at full effectiveness without the right level of caffeine.

Education Standards: Don’t Throw Rocks At The Swots

There has been a lot of discussion on how top maths students in schools in the UK, don’t keep up with students in schools in Asia. Funnily enough the difference is much smaller for British Asian kids. Which is an interesting thing given that people are concentrating on what the schools should be doing.

Now it’s not wrong to say that schools could do with improvement; no matter how well the school system is doing, it could always do with improvement. In particular for this particular report, looking at the top performers in a class is worth doing – it is natural, but unfortunate that the top performers in a class are often left just to get on with it. They are after all performing well enough even if they could do better if pushed.

But as can be seen from the performance of British Asians, it’s more than just the schools. Things may well have changed since I was at school, but back then there was this weird cultural thing.

Those of us who were seen as being good at maths were always thought of as a little odd — geeks, nerds, swots, and the like. Of course if you were good at other subjects you got it too, but it wasn’t as bad as being good at maths. Not really as bad as genuine bullying, but it generates an atmosphere where it’s ok not to try too hard at maths.

Does this still go on? If so, it would explain these results.

Raspberry PI Alternatives

The Raspberry PI is a pretty cool device, but it is not the only small cheap computer around, and given that the PI is more hardware hacking orientated I thought I’d dig up some links for some of those other devices. Especially as I’ve got two Arduino projects on the go.

There’s actually a surprising number of devices out there; some running Linux and some running Android. And in a surprising variety of form factors; I’ve avoided looking at the simple boards – the point here is to look at devices that are different :-

  1. The Trim-Slice looks quite an interesting device, but all seems to have gone quiet since March 2012.
  2. The Giada Q11 is a similar device which is about the size of a VCR … or a 3.5″ external hard disk enclosure.
  3. The Cloud Client mini PC is a touch smaller being roughly the size of a double-CD case.
  4. The CuBox is more square than the rest and is roughly the same size as a mains plug.
  5. The Cotton Candy is an ARM in a USB stick; a cheaper option but possibly via Ebay is the U2, although most cheaper options don’t have quite the same features as the Cotton Candy.

This is not to imply that there are not others out there, nor that these are “better” in any way. I’ve not used any of them.

Iceland: “It’s All The Fault Of The Councils”

The boss of Iceland has come up with this.

To which the only appropriate response is “horseshit”.

His argument is that councils (or local authorities) award contracts based solely on price. Now I am not directly involved in the tendering process, and indeed not directly involved in the council tendering process, but I do have some familiarity with the process – sometimes I am one of the “quality gates” to get past in an area which works to many of the same rules as local authorities.

And nobody awards contracts based solely on price. At least not if they want to keep their jobs for longer than 10 minutes.

It is true that the public sector will award a contract based on price with all other things being equal. But if you want to supply burgers to all of the schools in the county of Rutland, you’ll probably have a huge pile of paperwork to complete which includes specifying the size of the burgers, and what’s in them.

Once all that paperwork had been sent back to the council, some poor unfortunate has to go through all the paperwork whittling down the responses to those who meet the criteria – strange as it may seem an invitation to tender for supplying 10,000 beef burgers will solicit responses from people willing to supply 50 chickens! Once the responses have been whittled down, the cheapest response is selected – if there’s no good reason to reject it.

Does this result in a downward pressure on price? Of course it does – and councils would be criticised if they did not exert downward pressure on prices. But it doesn’t encourage corrupt practices.

The Earth Is Pebble-Dashed …

So today in addition to being subject to a near miss – the cosmic equivalent of being given a close shave by a Samurai with his (or her) Katana – we also had an unannounced visitation by an asteroid that crash-landed in Russia causing a considerable amount of property damage, and more seriously some injuries.

Now this doesn’t happen every day, but in the lifetime of the Earth it does happen pretty frequently. As is evident from our nearest neighbour which looks as though it has been bombarded in some sort of celestial war. And indeed, the evidence can be seen on Earth if you look close enough; and that list just includes the largest impacts – events such as Russia today simply don’t show up.

Now there is not a great deal we can do about this as individuals, so as individuals we may as well forget about it – the chances of being killed by a meteorite are pretty remote but as it turns out only slightly less likely than being killed by a terrorist!

As a species however, we have reached the point where we can start doing something about it. If that is, we want to invest the resources into doing so. Admittedly we have started looking but simply knowing we’re all going to be killed by a dinosaur-killer isn’t enough – we should be able to do something about it. Perhaps there isn’t much we can do about a dinosaur-killer.

But we should be able to do something about smaller dangers. If we want to.

If we told the military that they will have to change the kinds of really expensive toys they get, we can probably start some form of meteor defence programme without having a dramatic effect on the economy. After all, ultimately a large meteor is as dangerous as an all-out nuclear war.
