For Your Eyes Only
Rereading this, a collection of short stories incl. A View to a Kill, For Your Eyes only.....
FYEO was published in 1960 and almost reads like a history piece. Good fun though

Two books on economics both of which I have read > once:
https://www.amazon.co.uk/Dr-Strangeloves-Game-History-Economic/dp/0140299866 and
https://www.amazon.co.uk/False-Economy-Surprising-Economic-History/dp/0141033703/ref=sr_1_1?s=books&ie=UTF8&qid=1505998538&sr=1-1&keywords=false+economy
Both these books are about economic history - the former more about the economists themselves but a nice change from physics when you need one

Glad it worked. Tried to find the YouTube item again when I returned from Paris but couldn't, so just wrote the steps down

I would guess that the reason is an economic one. More demand for electricity esp. heating in cold weather, so charge more when you can. "Make hay while the sun shines" if you like, but not a very good analogy here.
Bob's point is also a good one with HEP plants being frozen up in winter

Great to meet David Anderson and others in Paris last week at the BOINC workshop organised by CERN.
One issue that came up was that new BOINCers often remark that the fan noise increases when BOINC is loaded. From a YouTube video I found that this can be reduced by marginally changing the maximum processor rate.
If one has HWMonitor (from CPUID) on screen and you then change the max processor settings by 1-5% one can see a drop in power consumption and fan noise with hardly any change in number crunching.
HWMonitor shows different data with different versions on different laptops (mine are HP with one remaining DELL) and if one tweeks the max power setting, you can see the drop in temperature and power usage.
With one of my laptops I reduced the power consumption from 30w to 20w and the fan noise disappeared by reducing the max processor power usage to 96%.
Steps: Control panel, power options, select a power plan (I use balanced) Change plan settings, Change Advanced power settings, Processor Power Management, Max Processor state: battery or plugged in.
ADJUST % slightly and watch change in power consumption &/or temperature
Couple of other points from general discussions in Paris:
a) Computer professionals seem to have older machines (32 bit) than volunteers who more often have 64 bit?
b) On PC Laptops, it is easy to change the settings when Closing the Lid so the laptop keeps on crunching but not on Macs? The app that does this is "not supported" by Apple apparently with the result that Mac users crunch an average of only 2 hours a day.
c) speaking to one of the CERN guys in a coffee break, CERN does not run as many experiments in winter as in summer because the price of electricity is higher then!

Purchased a s/h HP Elitebook 2570p off eBay, (Machine no. 8285120) put max 8GB RAM in it and 120 GB SSD. This crunched the WUs very well and at a fraction of my TU (DELL Xeons 8023146) electricity cost. However, after a few days, I got the message "This copy of Windows is not genuine...." Didn't stop the fast WU crunching with average credits > 4000 a day - easily the most productive laptop and almost half of the TU daily average of around 9000 credits.
Anyway got fed up with the notice so bought a Win7 licence off eBay and installed it after a lot of trouble having to download lots of HP drivers.
When I downloaded BOINC again, I got a new machine number 8330266 so I merged this with 8285120 getting message that the latter had "been retired" (shades of Blade Runner....) so the no. 8330266 is the current one.
I keep my own daily figures of credits for each machine and decided to check these against FreeDC. The daily figures for 8330266 are identical to another HP machine: Elitebook 2570p when I check them on FreeDC and much less than my own credit figures which I check at the (roughly) same time every day.
Can anyone tell me what is going on here?

Yes Chris, very good choice. Next time I go there I will have a guided tour. For a laugh, I might even buy some scented moustache wax for my brother for Christmas!

Yes saw it this afternoon but sadly, not the SETI we are looking for.
SETI in the form of the sarcophagus of pharoah SETI 1 is in the Crypt of the Sir John Soane museum in LIncoln's Inn Fields behind Holborn underground station. Who was Sir John Soane? Very famous architect who built the Bank of England building among others.
Amazing collection of stuff where hardly any of it is labelled [http://www.soane.org/url][/url]

That looks an interesting read. If you like railway history, Christian Wolmar has written several books on this http://www.christianwolmar.co.uk/

If you are into spy trilogies, then John Gardner's The Secret Trilogy might be of interest http://www.john-gardner.com/

Dear Suzie-Q
I brought my 3 daughters up on Winnie the Pooh, actually a collection of 4 books - 2 poems and 2 stories and managed to get the books signed by Christopher Robin! They all became teachers at some point and nice to think they read the Winnie the Pooh stories to their children.

Current reading: Just finished Most Secret War by R V Jones - techie WW2 history or early days ECM warfare. ISBN: 978-0-141-04282-4

Now: One-third through Ray Monk's Inside the Centre, The Life of J. Robert Oppenheimer - biography of brilliant but often strange guy. ISBN: 978-0-09943-353-8 Bonus of this book is that the author explains physics clearly where necessary.

Both the above books have superlative reviews.

George E

Dear Tom
Stupid question time......At present, I just plug my TU and laptops into my 13 amp power sockets - what is the advantage of having a power supply? My laptops seem to cost about 10p (say 13c) a day to run and the TU around £1 a day.
TIA
George
