Jane Eyre, Or: The Bride of Edward ‘Crazypants’ Rochester:
BLANCHE INGRAM: Oh great. The dude I’m trying to marry likes wearing bonnets and crinolines. I cannot believe this is happening to me again.

fresh blood, raw meat, mud, stagnant water, fresh fish, otters, and some species of toad

What do fresh blood, raw meat, mud, stagnant water, fresh fish, otters, and some species of toad have in common?

They all smell “pl’eng”.

good unintended consequences

Electric cars may reduce your air-conditioning bill?

Using summer 2012 in the Chinese capital of Beijing as an example, the team estimate that replacing conventional cars with electric ones could have reduced the heat by nearly 1 °C. That in turn would result in a reduction in air conditioning use in the city, leading to a drop of 10,686 tonnes in daily CO2 emissions.  [New Scientist]

Witch’s house?

From a distance, this could be a witch’s house in a forest.  But it's a termite mound!

coincidence? you decide

8:45. Phone rings.  Foreign accent, claiming that they are calling from Italy.  (I think not.) Wanting to talk to me about something to do with my kitchen.  I say “Do you know what time it is!” and hang up.

Another day, another scammer, I think.

10:45. Phone rings.  Foreign accent: “Are you getting unsolicited marketing calls from overseas?”  Turns out, they are trying to sell me a device that stops overseas calls that my membership of the Telephone Preference Service doesn’t stop.

“So, you are making an unsolicited call to sell me something that will stop people making unsolicited calls to sell me something, because you know I don’t want unsolicited calls to sell me something?”

What a coincidence this happened so soon after an unsolicited call to sell me something, at an unusually early time, where that first caller very carefully emphasised they were calling from overseas.

Second scammer called from 08451297936.


Update.

11:50. Phone rings.  Local accent (makes a change).  “Hello.  We’ve been informed someone at your address has been in a car accident.”

“Absolutely not.  You’re a scammer.”

Third scammer called from 02037695670.

It must be the (slightly) warmer weather bringing out all the creepy crawlies.

a different sort of eclipse

A colleague dashed in my office and said “have you seen the balloon?”  Well, there are often hot-air balloons in the sky, but he seemed quite insistent, so I got up to have a look.  And immediately went to grab my phone to take a photo.

17:34 GMT: the balloon has gone down
(Our windows at work don’t open more than a crack, for safety reasons it seems, so I had to photograph through the glass almost into the low afternoon sun, hence reflections.)

We all stood around watching and wondering, and then the eclipse started:

17:37:39 GMT: note the thinning at the base of the red giant,
as its internal pressure can no longer support it
17:37:57 GMT: the eclipse/collaspe is well under way
17:38:09 GMT: it disappears so suddenly
17:40 GMT: last contact

TV review: Arrow, season 2

So, Oliver Queen sort of saved his city from Malcolm Merlin’s plot (apart from the big disaster that essentially was the plot), but totally failed to save his friend Tommy. Now that his raison d’être plot is over, what’s a Vigilante to do?
My name is Oliver Queen. After five years on a hellish island, I have come home with only one goal – to save my city. But to do so, I can’t be the killer I once was. To honor my friend’s memory, I must be someone else. I must be something else.
Well, he can reform (not be the killer he once was, that is, he was just last year), get a new name and a proper mask, and still go after bad guys to “save his city”. Save it from what precisely is not initially explicit, but soon enough a new Big Bad appears, and Oliver is now hampered in his fight by his new morality. And by the ever-increasing number of people who know his “secret” identity: a regular Scooby Gang’s worth.

The villain of the week, plus the arc, are again fun. People fight. People agonise over fighting and over putting their loved ones at risk (hint: keeping someone in the dark about Important Facts in order to Protect Them never works). People become super-strong psychopaths. Some people die. Other people stop being dead. Yet again, the best bits are the flashbacks to The Island, and what happened there to make Oliver Queen the recovering psychopath with superior archery skills he is today.

Worth watching.

and then the sun came out

Here is the solar PV data from dawn to dusk, plotting production against time.  The orange background is what we would expect with a clear sky (no cloud) and full sun (no moon) at this time of year.  The black line shows the production today.  It is way down in the morning, due to the clouds.  But that dip: that’s the eclipse!

And then, for the rest of the day, almost perfect sunshine!  The black line goes up almost vertically, as the sun comes out just after 11am, and stays out for the rest of the day.

the eclipse ends, and the clouds turn to light haze


Harumph.

fabulous Faroes

I had thought that I would have been disappointed to have travelled to the Faroes to see the eclipse, only to be clouded out. Then I saw this.

detecting the eclipse

Although we couldn’t see the eclipse, our solar PV system detected it.



Here is the solar PV data from dawn up to 11 am, plotting production against time.  The orange background is what we would expect with a clear sky (no cloud) and full sun (no moon) at this time of year.  The black line shows the production today.  It is way down on average, due to the clouds.  But that dip: that’s the eclipse!

And the weather now?

11:20, full sun
Typical.

the safest way to view the eclipse...

...is from behind a thick bank of cloud.

9am, eclipse well under way
9:30, close to maximum
10am, getting lighter

goodbye sun, goodbye electricity

I’m looking forward to the eclipse on Friday, and also to see the effect it will have on our solar PV generation.  Of course, it’s not just our solar PV...

but it won’t be sunny tomorrow

it's not cricket


This is what playing cricket looks (and sounds!) like to some English, too. The only game you time with a calendar, and then it ends in a draw. As I understand it, you keep score simply in order to know when to stop playing.

I’ve seen this before, but was reminded of it by BoingBoing.

nowcasting fail

Prediction is very difficult, especially about the future.
— Niels Bohr (attrib)
Or even about the present, it seems.

We have grown more attentive to the weather since installing solar PV.  Knowing when it is going to be sunny for a long period is useful for scheduling clothes- and dish-washing. (Sunny weather used to be “washing day” for hanging clothes out to dry; now it’s washing day for powering the washing machine.  Plus ça change, plus c’est la même chose.)

I gave up on the default weather app that came with my phone long before we installed solar PV, and downloaded BBC Weather instead.  I’ve had my issues with the BBC weather app before, but today was quite extreme.

Here’s what my phone says the forecast is for the town where I live.

today’s weather forecast, as of 7:55GMT
That doesn’t look good: thick cloud at 8am, thinning to light cloud during the mid-morning, thickening again around noon, then rain later.  Okay, not a nice day at all.

Hang on a minute.  Thick cloud at 8am?  But, out the front window it looks like this:

today’s weather, at 7:55GMT
I know weather prediction is supposed to be a hard problem, but getting it so wrong not for the future but now, well, that's another thing.

my sixth planet

I’ve seen all the naked eye planets: Mercury, Venus, Mars, Jupiter, and Saturn.  In fact, Venus, Mars and Jupiter have all been readily visible the last few nights.

But tonight was a first: Uranus is quite close to Venus, and so finadable with binoculars, particularly with the 15×70 pair we bought for comet ISON (but then never saw comet ISON). So, tonight I saw Uranus for the first time.

Some people can allegedly see Uranus with the naked eye; I certainly can’t.  And with tonight’s slightly hazy sky, it was a very faint dot, even with binoculars.

I didn't manage a full four planet night this time, as Mars was too low by the time I went out, but still.  Six planets!

academic stress

Here’s an interesting article about stress in academia, from last year:
Mental health problems are on the rise among UK academics amid the pressures of greater job insecurity, constant demand for results and an increasingly marketised higher education system.

University counselling staff and workplace health experts have seen a steady increase in numbers seeking help for mental health problems over the past decade, with research indicating nearly half of academics show symptoms of psychological distress.

In the past, I’ve wondered aloud: the academic contract is for a 38 hour week [hahahahahaha]; the academic culture is one of long hours [60 is typical; 80-90 not unknown]; promotion criteria seem to be based on expectations that are possible within that culture, but not within that contract; when are we going to have the first claim for constructive dismissal?

wishlist

Here’s another book for the wishlist:
The word-hoard: Robert Macfarlane on rewilding our language of landscape

For decades the leading nature writer has been collecting unusual words for landscapes and natural phenomena – from aquabob to zawn. It’s a lexicon we need to cherish in an age when a junior dictionary finds room for ‘broadband’ but has no place for ‘bluebell’

(re)discovering the year

We've had our solar PV system for over a year now.  One of the many plots we make is its output, measured every five minutes through the day, for each day:



(The horizontal time axis runs from 3:00am to 9:00pm GMT, and the vertical axis runs from January 2014 to February 2015.  The colour indicates the average production in kW in the five minute interval.)

Hey, there's a pattern!

We started generating in January last year, as the days were getting longer.  The changing day length is clearly visible.  Where we live, sunrise to sunset is a mere 7 hours 41 minutes on 21 December, and a whopping 16 hours 48 minutes on June 21.  I got those times from a website, not our generation data.  The system doesn't switch on exactly at sunrise and switch off exactly at sunset: it depends on clouds and scattering and stuff.  But the sinusoidal trend over the year is clear from the chart.

We get more power in June not only because the sun is up for longer, but it also generates more at peak, because the sun is higher in the sky, shining down fully onto the panels, not at an oblique angle.  So last June we saw this average over the month:



(Here the horizontal time axis runs from 3:00am to 9:00pm GMT, and the vertical axis runs from zero to 8kW.  The orange regions indicate the minimum, lower quartile, median, upper quartile, and maximum generation at that time, over the month. The black line indicates the monthly mean generation at that time.  The number is the average kWh production per day.)

The statistics show how variable the generation is.  On the best June day we got 53.63 kWh, but on the worst June day generated only 18.35 kWh.

Come December the generation plot looked like this, narrower and lower, with only a third the average generation:


There is still massive variation, from 27.63 kWh to a minuscule 0.34 kWh (it barely seemed to get light at all that day!)

But even an average of 12 kWh/day is a lot better than nothing!
