So let me get this straight

It's bad when we pay the bankers massive bonuses, but it's also bad when we don't?

The referendum

With all three main parties having a three line whip, I guess we should consider ourselves lucky that it got as many votes as it did.

I do find it really frustrating that the MPs who are there to represent our interests clearly don't give a crap what the people think.  I know that those in government think that they are our rulers and that we should let them make all our decisions for us, but I had hoped that a few more of the backbenchers might be on the side of the people that they work for.

So I'm wondering what the next step is.  Do we all just sign another petition (https://submissions.epetitions.direct.gov.uk/petitions/356 looks like it's doing ok, at over 30k signatures already) and keep on making them whip their MPs, while noting carefully who slavishly obeys their political masters, so that we can actively campaign against them next election?

If anyone has any better ideas, I'm all ears!

Those Neutrinos

There's a bit of a hubbub going on about the OPERA neutrinos and how they seem to have travelled faster than the speed of light.  I don't know enough about relativity or quantum effects, but wondered if there might be a more simple explanation.

It's been suggested by some that maybe Neutrinos just do travel a little bit faster than light.  Those people have referred to a supernova that occurred a little while ago, and pointed out that the Neutrinos arrived hours ahead of the light from the supernova, so perhaps Neutrinos are just a bit quicker and this is another example of that.  The thing is, if the Neutrinos are just a bit quicker than light to the extent represented by the OPERA experiment, the Neutrinos from the supernova would have arrived here years ahead of the light, rather than just hours.

So I got to thinking that maybe that there's something between the transmitter and receiver used in the OPERA experiment that made the Neutrinos faster than light for very brief periods of that journey, and the same something lies between Earth and the supernova.

So we need something that there is a relative lot of between the OPERA transmitter and receiver, and a relative little of between earth and the supernova. 

Could it possibly be matter?

The Neutrinos passing from the transmitter to the receiver for OPERA moved through the Earth.  The Neutrinos coming to Earth from the supernova moved through space - an almost complete vacuum, but the key word is almost.  Could matter speed Neutrinos up?  If so, the relatively tiny amount of matter in space could have accounted for a 3 hour difference between light and Neutrinos over a sufficiently big distance (and the distance to the supernova was something like 160,000 light years).

Anyone know if that's at all plausible?

Climate Change - why it bugs me

One thing that really bugs me about the whole Climate Change thing is the way everyone asks the wrong questions.

The way that I see it, there are three questions being asked here:
(i) Is the climate changing?
(ii) Can we stop it changing?
(iii) Whose fault is it that it is changing?


I think this is very short sighted.  We're missing several very important points.  I'm willing to concede that the climate is changing, largely because it should be changing.  Whether you believe it's because we're emerging from a little ice age or because of the crap we're pumping into the atmosphere, I'm willing to accept that temperatures over the last hundred years or so have showed a slight upward slope (although that does seem to be coming to an end for now).

What we're not asking though is what impact will a hotter world have on humanity (and stop claiming you're trying to "save the world" - the world would be just fine if the temperature was 50 degrees higher, it's humanity that would suffer, and humanity that we're trying to save).  I've seen reports that a hotter UK would lead to less deaths overall, and not have any serious downsides.  What other impacts would there be?  Let's see what we can figure out, and then we can ask the next very important question: are the changes for the better overall?

Only if we decide that they're definitely not for the better should we then look to point (ii) above - can we stop it changing?  But at the same time, we need to ask: Would we be better off by mitigating?  People often refer to the Stern report, where I believe it was reported that we would be better off providing money to mitigate rather than preventing the changes.  That means that if the sea levels will rise by x metres, it's better overall to provide money to build sea walls or move people elsewhere than it is to cripple our economy to prevent the warming.

If the world is warming (and I'm not saying that it's not), I believe that it cannot be 100% negative however you look at it.  Plants will grow faster, less people will die of hypothermia in the winter, maybe we can generate more tidal/wind energy as a result of the changes, etc.  What we need to consider is how we can use the positive aspects and deal with the negative aspects in the most efficient way, rather than to assume that any change is negative and nothing good can come of it (except the chance to raise lots more in taxes).

As to point (iii) above - whose fault it it?  Who cares?  If the climate is changing, we need to deal with it.  If it turns out that mankind had nothing to do with the changes, we still need to assess how we'll be affected and decide how we want to deal with it.  If it's all our fault, it changes nothing, except for the most loony of eco-loons, who would no doubt say that if it's a natural process, we should just let it happen and who cares if it affects millions of people...

River Song's first meeting with the Doctor

It was suggested way back in Silence in the Library that River and the Doctor are having a relationship in opposite directions.  This is a cool idea - a mysterious woman from the Doctor's future who knows him intimately (or at least that's what's implied) but who he's never met?  Cool!  And to have their timelines running in reverse relative directions, so each time they meet, it's the next time for the Dr and the previous time for River?  That's cool.  A pain to stick with (so some wiggle room is required) but cool.

But this would surely mean that the first time River meets the Dr should be the last time the Dr meets River - and the episode Let's Kill Hitler implies otherwise.  Or does it?

At the start of the episode, Amy and Rory get the Doctor's attention by drawing a massive crop circle that he spots in a paper some time in the future.  But which Doctor is it?  It's somewhat taken for granted that it's the same Doctor that we last saw in A Good Man Goes to War, but how do we know that he hasn't been around and had lots of adventures since then?  What if this is the Doctor at the end of his time, aged 1300+ ?

Then the episode takes on a different tone - when River poisons him, and there's no known cure for the poison, he hops in the TARDIS and goes to get help (the Doctor from Amy and Rory's wedding?  Or from the end of the season episode which is apparently something to do with the wedding of River Song?) then heads off to meet the girl on the edge of the lake and gets shot (the Impossible Astronaut).

The timing works (32 minutes until he's dead, and he's in Impossible Astronaut for less than 32 minutes before being shot iirc) and the change of outfit seems odd otherwise, given how that was a big thing about last season (with the Doctor's jacket in the Time of Angels).  The only questions that then remain are: was it even the real Doctor (I thought it would be the ganger Doctor that was killed on the lake edge - but maybe he's the Doctor that keeps on?) and what happened to River's Regenerations (could the Doctor have taken them away from her, knowing that she won't need them?  Could that let him somehow survive being shot on the edge of the lake?  Could it give him more than 13 lives?).

Doctor Who - Night Terrors Review (warning: Spoilers)

I managed to watch the latest Dr Who last night.  It was called Night Terrors, and was (in my opinion, anyway) a big step up from last week, but still not as good as some episodes we've seen.

The episode started off interestingly.  It seems that with River sort-of dealt with last episode, the Doctor and his pals had little to do.  They're just hanging out in the TARDIS somewhere in deep space.  Meanwhile, there is a little kid on an estate in the UK somewhere who is afraid of everything.  He's so scared that his fear manages to send out a telepathic message to the Doctor's psychic paper saying "Save me from the monsters"

So the doc and friends decide to go and help the kid (well, the Doctor does anyway - Amy and Rory seem less than enthused about the idea).  This involves lots of knocking on doors but gives the impression that they're not really that good at the job.  They don't seem to ask anything that would lead towards finding the kid.  This bit starts to drag on a little (I know they're establishing some details about other people around, but it still feels a little overlong) then thankfully the Doctor spots the boy in a window.

At about this time, Amy and Rory get into a lift (which we're told the boy is terrified of) and plummet for no particular reason.  They wind up in a creepy doll's house.

Long story short, the Doc gets into the house and saves the day, by persuading the boy that he made all of the bad stuff, and only he can stop it.

It was a reasonable episode with a nice message and feel to it, but some of it felt a little rushed (like how Amy and Rory were dumped into the house by using an elevator) or a little slow (like the knocking on doors, or waiting for the Doc and the Dad to open the closet.

I'd give it a solid 7 out of 10.

Bury Council pissing away money

Via the Register, we learn today that Bury Council has bought 22 Ipads for it's binmen, at a cost of around £9,000.

They claim:
...the products, made by Apple, could produce significant savings by helping to reduce the number of bins missed by trucks and therefore the number of trips made by the vehicles.
I'm really not sure how.  You either get the bin, or you don't - having a touchpad isn't going to help you remember which bins you're meant to be picking up, is it?

The council, which collects rubbish from 83,000 houses each week, revealed that there were 4,228 reports of missed bins last year. Costing £40 each to revisit, it spent around £170,000 going back to empty bins missed on rounds.
So 83000 bins collected each week, and they missed 4000 in a year.  That's a miss rate of about 1 in 1000 - doesn't sound too bad.  So I guess what I'm wondering is why they have to spend £40 to revisit - surely they have other binmen in the area the next day, why not pick up the rubbish then?  Each household would only have about a 1 in 20 chance of having their bin missed once a year, which is surely low enough that people will manage.

What I don't understand is why having an ipad would help.  Are they going to program the locations of all of the bins onto the ipads?  If so, why not just get a map?
A council spokeswoman said: "For a modest investment of £9,000, this technology should save us many thousands of pounds, provide residents with a better service, and promote recycling.
How the hell does it make any difference to recycling?
"We know how much residents value a responsive and reliable bin collection service. This system should ensure that the number of missed collections is reduced to an absolute minimum, because any problems are reported in real time to our customer contact centre.
So the problems are reported in real time - and then what?  
"The system should also allow us to respond more quickly during the winter to any enforced changes in the collection route."
The council also said the soaring landfill costs contributed to the decision.
The spokeswoman added: "We need to urgently improve our recycling rates to avoid passing on crippling landfill taxes to local residents, which is already costing every local taxpayer £134 a year each and is set to rise to £250 a year if we keep dumping waste in landfill sites.
"This new technology will help us to log and monitor this, and help us in our ongoing efforts to promote recycling across the borough. It is absolutely vital that we increase recycling and reduce the amount of waste we send to landfill."
This article was originally published at Guardian Government Computing.
 So you log the problems - well done.  I don't see how this reduces waste - from the sounds of it, they hope that it will increase the efficiency of collections, and thus increase the waste put into landfill...

Call me a cynic, but I wouldn't mind betting that the person who signed off on this purchase is either related to or good friends with at least one of those who gets a shiny new ipad...

Doctor Who - Let's Kill Hitler - Review (warning: spoilers ahead)

I was very excited about the return of Doctor Who. Lots of unanswered questions out there, and lots of things to be revealed. I couldn't wait to find out what Moffat had in mind. So I should have been thrilled with Let's Kill Hitler, but it didn't quite come together for me.

I think most long term fans of Doctor Who like to try and figure out what is going to happen next, and how the various paradoxes can be resolved. I certainly have my own theories, and it can be quite fun to discuss with others, and compare with what actually happens.

I also have a reasonable feel for the story and how things sit, so it doesn't sit right when new characters are introduced all of a sudden, and retrospectively revealed to be really important. At the start of Let's Kill Hitler, we meet Mels* (which it later transpires is short for Melody). She's annoying, loud, constantly in trouble and deeply irritating, and is apparently Amy and Rory's best friend (and is in fact the cause of them being together).

My thought at this point in time was that she was some kind of mind reading alien who'd inserted herself into Amy and Rory's life to get access to the TARDIS. Alas, I was wrong.

So, thanks to Mel's shooting the TARDIS (for no real reason - just because... And that's always a bad reason for something to happen in a tv show) the gang manage to accidentally save Hitler from a time travelling shape-changing justice robot, manned by a bunch of miniaturised people (who incidentally seem to have bugger all idea how to run a military operation - and if it wasn't a military operation, it should have been).

Along the way, Mel gets shot and regenerates into River Song, but it's not the cheeky, flirty, funny River Song that we know. It is instead a River Song that acts like a spoilt teenager. I gather that was probably what they were aiming for, but someone hasn't done the maths (or possibly there's something else going on - we can hope) as they left the kid in 1969 (where it appeared 10ish?), Amy is around 23, so started school (age 5) in 1992ish? So the kid would have had to grow up from 1969 to 1992, then regenerated to be about 5. That would have meant (assuming age 10 at 1969) a total age of 33 when she looked 5. By the time she's grown up again to age 23ish, she'll have a real age of 51 - so why act like a stupid kid? It just grated - I like River Song, but didn't like this character that looked like her. Maybe that's the point.

Anyway, back to the title of the show. Let's Kill Hitler! Apart from one throwaway line at the start of the episode and saving Hitler from the aforementioned time travelling shape-changing robot, he gets shut in a cupboard and left there. The title is completely misleading. The episode has the great backdrop of Berlin 1938 and does nothing with it. Hitler and the question of his crimes (which he hasn't yet committed) are ignored. Hell, even the shape-changing time travelling robot is nothing more than a gimmick, as we never find out where it's from, who built it or where/what the "mothership" is. It seems like it's just there to pad out the episode a little bit.

This episode has three main strands: Hitler, the shape-changing time travelling robot and River Song, and really each one of them could easily fill an episode. It seems a shame that the first two are neglected in order to develop the River Song story, perhaps a bit quicker than necessary**. There is some joy in leaving some things unknown.

Overall, I'm glad Dr Who is back, but don't really feel like it's back yet - if that makes any sense. I'm hoping that the bits that were overlooked in this episode are revisited later in the season, and that next weeks episode is better.

* I know that technically she's not a new character, but this aspect of her is new - she was a big part of Amy's past, and has never been mentioned, or referred to. Like the Doctor says, she wasn't at the wedding (and yes, we know why she couldn't be there, but she couldn't have known that her older self would be there, so why wasn't she?) - surely Amy would have mentioned if her best friend couldn't make it?

** And does anyone else remember River Song describing the first time she met the Doctor? She says something like, "Here was this man that I knew nothing about, but he knew everything about me." Doesn't sound all that much like what happened... I'll have to re-watch and look up the quote

G+ invites update

So far I've had over 1,000 requests for G+ invites, although there is some duplication included in those figures as some people have entered their email address more than once. I reckon I've sent out over 900 invites to real people.

Out of those people:
14 have left a rating on the market
11 paid £1 each (of which I received 70p)
9 have individually emailed me to ask for an invite
6 have left comments on the market

Since yesterday morning, the invites are coming in fairly steadily at about 15 per hour. The peak time was between 10pm last night and 2am this morning, when we hit about 17.5 per hour.

Sainsbury's pay

I used to work for Sainsbury's.  I see from the Guardian that people are protesting the current wage levels.  It's tempting to point out how lucky they are (when I joined, I was on £2.73 per hour) but probably more honest to point out that they do have a perfectly good option.  If they don't like the pay there, they can get another job.  If enough people did that, perhaps Sainsbury's would up their wage to keep their staff...

Looking at the article, the main gripe seems to be that Sainsbury's makes a massive profit, so should pay more.  According to the London Stock Exchange website (no idea if that link will work - if not, search for SBRY on the site) they have a market cap of around £6 billion, and they're profits were £665m.  That's around 11%, which is higher than average, but not necessarily excessive (most projections I've seen reckon on 5%-9% being normal).

But suppose they're right, and the bosses are doing absolutely the wrong thing by keeping all these massive profits (and presumably using a certain amount to grow the business?), and the excess should be spread out amongst the staff.  First we need to determine what's the excess.  A return of 5% would be poor, and would mean lots of people selling shares (driving the price down further and thus calling into question the long term viability of the company, and incidentally costing anyone in the employee share plan lots of money, but never mind all that) but might be acceptable to the staff - that would give £363m or so to spread amongst the staff.

There are two ways the cash could be distributed:
flat amount to each member of staff
150,000 staff (from wikipedia) working out at about £2,420 each, or £1.19 per hour, taking them to £7.50 per hour.
or
according to their current salary
total wage bill was ~£2bn in (from here (warning: pdf)), so adding £363m would increase the total by 18% or so, so the basic £6.31 mentioned in the article would go up to £7.45 per hour.

Note that this is not what they can afford, it's the most they could give if they were willing to seriously risk the long term viability of the company, so asking for £8.30 per hour is not really reasonable.
