A course in self-publishingAs bloggers, we self-publish, but online (only?). The HNF recently offered a one day course in self-publishing, the end product being either an E-book or a traditional paper book. I liked the idea of such a compact course and so coughed up the 60€ and went along last saturday.The teacher was Dr.Mareike Menne, a lecturer in history from the local university. The course was in German, as were all the links and most references and tools, so this write-up is really for my German readers. Practising what she preaches, she has her own small publishing house Eire Verlag and writes an employability blog aimed at liberal arts academics who otherwise find it a problem getting a job :-( The course was very useful and covered a lot of ground : Pro and Contra self-publishing, Links to the German bookdealers' reference database etc, Copyright law, Taxation, Pricing, getting an ISBN number, (social) networking amongst self-publishers e.g. via Federwelt, useful reference books. Getting into the world of tools and service providers, she showed us Tredition, Xlibri and BOD. For those wanting to produce paper books, she linked us to a printing house portal for getting competing printing offers, Linotype (for buying the fonts you use, she recommended Garamond etc), and an online printing shop. As far as E-books are concerned, she linked us to Neobooks and recommended both Calibre and Papyrus as tools. There followed a bunch of tips about marketing (selfpublishers have to do their own selling!) with a number of links to relevant literature. Who took the course and what are their projects? 11 people, only 3 men but 8 ladies. I was the only person attending who had already had books published, the rest were hopeful neophytes. The projects included a small poetry collection (good luck with that), a biography, a children's fantasy tale, a management consultant's handbook etc. Experimenting with the toolkits recommended, I took a 3-page article from my website and "poured" it almost unchanged(!) into a text-to-print toolkit formatting it to get a 32 page broschure of size A8 (=a pocket guide) and sent it to a printer who prints one copy for free to see if you like his work. I'm now waiting for the hard copy to arrive in the mail :-) If that works out OK, I may try generating a larger book in black and white, then if that's OK, a motorcyclist' travel guide with lots of colour photos. We shall see :-)
So can I recommend Mareike's course? Unreservedly! I found it very helpful and delivered at a pace all could understand, she is obviously an accomplished lecturer. Locals may like to attend if and when it is repeated :-) Comments (1) Tuesday, February 23, 2016
Kafkaesque koffeemachine kaos :-(Last tuesday I told you about my frustrating fight with the photocopier. Today I continue that story to tell you about the Kafkaesque koffeemachine kaos, which is in the same vein :-(
Still frustrated from losing the fight with the photocopier, I found the coffee-machine to be displaying the message "Water tank empty"; just my luck, I thought and took the jug to the men's room to fill it with water. Putting the water into the machine, I merely succeeded in changing the error message to "Drip tray full." It really was full to overflowing, so I made a second trip to the restroom, carefully carrying the drip-tray horizontally while regretting wearing suede shoes that day :-( Back at the machine, I found that some inattentive hooray-henry had made himself a coffee despite the drip-tray being missing (stupid machine didn't inhibit that) with the result that there was a mess of coffee dregs overflowing the tabletop where the coffee machine stood :-( A third trip to the restroom was needed to get some paper towels to wipe up his mess :-( Returning to the machine, I found it now displaying the message "Out of beans, please refill.", so off to Miss Useless to get a fresh bag of coffee beans. She came back with me, and watched me refill the bean hopper, then pushed me aside to get a black coffee for herself. When it was finally my turn, I selected "Latte Macciato" and pressed the start button. FAIL! The machine now displayed the message "Milk pipe clogged, please clean the machine!" Frust!!! So I just gave up, went across the road to the copyshop, got my copies made immediately, giving me time to duck into the local coffee shop for my "Latte Macciato", both of which I should have done in the first place to save myself all that frustration and get my blood pressure down to normal :-)

Ticket avoided ;-)
So I pulled over resignedly, whipped off my helmet so that he could see I was just a harmless old fogey, & hung my shoulders dejectedly. Body language. "Ok, Grandad, what excuse this time? But one I've never heard before if you want to get off the ticket!" Think fast! "Well you've read all about those gravitational waves in the papers? It was one of them that just came through!" "Say what?" "They distort space and time. So when the gravitational wave passed through, it compressed the time dimension and dilated the distance dimension. So your LIDAR divided the dilated distance by the compressed time and calculated a faster speed even though I was doing EXACTLY the speed limit! It's general relativity, you see :-)" I smiled innocently. "Well, that IS a new one, Grandad, so I'm letting you off as promised; but ride more slowly and carefully in future. Have a nice day!" he grinned. Thank you, Albert Einstein, you saved my bacon :-) Comments (1) Wednesday, February 17, 2016

The photocopier fiasco :-(Awhile back, I was doing some consulting for a UK company in their west-of-London offices in Sluff. Yes I do know it is spelled Slough, but the syllable OUGH in British English has 10 different pronunciations, so I get to pick the one I like least ;-)
Having set the scene, let me complain about their stupid photocopier. It was situated out in the corridor, down at the end of the hall, way past the rest-rooms, lest its noise disturb the office "work"? I asked one of the bimbos to make me 3 copies of 4 pages, but she objected that she didn't work for me (actually I never saw her working for anyone else either) but gave me a copy-card so I could make my own copies. Arriving at the end of the corridor, I saw the copier was displaying a message "Out of paper" on its barely legible tiny LCD display. Of course there was not a single packet of paper in the cupboard on which the copier stood, so I had to traipse back to Miss Useless to get a new packet (she only hands out one at a time!). Meanwhile, it turned out, some hooray-henry had brought his own 2 sheets of paper and made his 2 copies, leaving it empty of paper again, but now with a new error message "Out of toner". Again, the cupboard was bare of replacements, so I had to traipse back to Miss Useless again to get toner. The toner came as loose powder because some cheapskate bean-counter in the purchasing department had found it to be marginally cheaper than a pop-in toner container. So, holding it well clear of my light-coloured flannel trousers and suede shoes, I tipped toner into the container, getting my sweaty hands filthy in the process :-( I needed a trip to the mens' room to clean the toner off before I could proceed. I then loaded my packet of paper, and pressed the start button. Wrong! Hooray-henry had left the paper-orientation on "landscape" whereas I (and most other people) needed "portrait" so my first copies were useless :-( It turned out that after refilling the toner you had to press a half-hidden button to tell the stupid copier that you had done so. I didn't know that. So the copier, thinking its toner was almost all gone, tried to print the copies as black as it possibly could. This resulted in my copies being 100% black :-( Losing my cool, I thumped the copier which responded with the uselessly unspecific error message "Error". A further trip to Miss Useless, who told me just to switch it off and back on again. Which I did, resulting in the error message "Paper jam" :-( So I gave up and went for a coffee; more about my subsequent kafkaesque fight with the coffee machine in a later blogpost ;-) When you remember that a consultant (me) cost that company upwards of €2000 per day and that the Misses Useless were probably on minimum wage (and overpaid at that!), just think of the savings possible with operating this misbegotten not-copying machine alone!

Valentine's day Photo :-)![]() Wilma and Blümchen (the pony), kissing over our garden fence :-)
Comments (3) ![]() Isabelle's mini-pony Skalli playing ball with the dogs :-) Doug (Canada) tells me that this tradition started in India ;-) " In spite of what you have been told by everyone, the truth is that Valentine's Day originated hundreds of years ago, in India , and to top it all, in Punjab ... It is a well known fact that Punjabi men, continually mistreat and disrespect their wives (Punjabans). One fine day, it happened to be the 14th day of February, one brave Punjaban, having had enough "torture" by her husband, finally chose to rebel by beating him up with a Velan (rolling pin). Yes....the same Velan which she used daily, to make chapattis for him....only this time, instead of the dough, it was the husband who was flattened. This was a momentous occasion for all Punjaban women and a revolt soon spread, like wild fire, with thousands of housewives beating up their husbands with the Velan. There was an outburst of moaning "chapatti-ed" husbands all over Jalandhar and Ludhiana . The Punjabi men-folk quickly learnt their lesson and started to behave more respectfully with their Punjabans. Thereafter, on 14th February, every year, the womenfolk of Punjab would beat up their husbands, to commemorate that eventful day. The wives having the satisfaction of beating up their husbands with the Velan and the men having the supreme joy of submitting to the will of the women they loved. Soon The Punjabi men realised that in order to avoid this ordeal they need to present gifts to their wives....they brought flowers and sweetmeats. Hence the tradition began. As Punjabis came under the influence of Western culture, that day was called 'Velan time' day. The ritual soon spread to Britain and many other Western countries, specifically, the catch words 'Velan time!'. Of course in their foreign tongues, it was first anglicized to 'Velantime' and then to 'Valentine'. And thereafter, 14th of February, came to be known as Valentine's Day!" Actually, the Punjab province is now in Pakistan. In 1947, with the dissolution of British India, the Punjab region was partitioned between India and Pakistan, so I'll give your version half-marks, Doug :-) Wednesday, February 10, 2016
A precursor to BMI ;-)Just last week a friend of mine was calculating her BMI (Body Mass Index = body mass divided by the square of the body height, 18 to 25 kg/m2 is normal) for dietary purposes, so I teased her, asking if she knew the method was originally developed for weighing cows ;-)Back in the first half of the 19th century cows were sold by weight but there were no scales at the cattle markets, so the buyer just had to believe the weight the salesman told him. Or did he? Not if you were James Chesterman, of Sheffield, England who saw that if he could get an estimate of the volume of the cow then he could use an average bovine density to calculate the weight. He came up with the empirical and necessarily correlative formula : Weight (in lbs.) = 3.35 x Length (in feet) x Girth(in feet) squared. Length was measured from from shoulder to tail and her girth behind the forelegs. BMI stood for Bovine Measuring Instrument ;-) In 1842 he was even granted a patent for Chesterman's Cattle Gauge which is a combination tape measure and circular slide rule. Measure the girth. Enter it by turning the quadratic scale accordingly. Then measure the length, and starting from that girth2-point continue on around the linear scale until you reach the length. Looking across to the weight scale you can read off the weight estimate directly because the factor 3.35 has been built in to the weight scale offset. How genial is that then? The Oughtred Society is dedicated to the preservation and history of slide rules and other calculating instruments. They sold a Chesterman's Cattle Gauge at their annual auction. It was bought by Nathan Zeldes of Jerusalem, Israel, who has a possibly interesting website and a good blog about common sense design. Put it on your blogroll; I have :-) Comments (1) Monday, February 8, 2016
R.I.P. Bob Snell :-(![]() We last saw one another 2 years ago in London, where he seemed rather frail to me. Now he has passed on, aged 70. Very sad! Condolences to Pat. One day this blog will stop suddenly and you can deduce I'd followed him. But until then life goes on : yesterday was dry with +ve temperatures, so I went motorcycling. Bob would have approved :-) Comments (1) Saturday, February 6, 2016
POTUS candidates from a German POVEd (USA) asked "What does the average German think of our top-runners?". This summary is derived from the German yellow press. It is Bild's reply to a selfish "Which POTUS would be best for us?"
Cruz (45) would revoke the Iran Atom-deal[-], criticises TTIP (but so do we) but would increase trade [+], more green cards [+] but
tougher border controls, born in Canada (which may eliminate him),
Trump (69), militarily unpredictable [-], opposed to TTIP & wants more growth [+], re-importing jobs (good luck with that!). Xenophobe [-], anti-Merkel[-], neo-fascist [-], (5)Billionaire despite multiple bankruptcies, Loudmouth. Mrs. Clinton (68), will lead anti-ISIS coalition, oppose Putin in Europe[+], Would push TTIP through[-]. Would naturalise 11 million existing illegal immigrants, pro-Merkel, Emailgate as Damocles sword, (100)millionaire. Has government experience [++], pragmatist[+]. Sanders (74), doesn't want to be the world's policeman[-]. Market socialist in the European style [+], would raise minimum wage, regulate banks better. Opposes TTIP[+], would naturalise 11 million existing illegal immigrants, but accept NO more to protect US jobs. Humourless [-], not a millionaire[-], Jewish not Christian which may lose him many fundamentalist votes; too pro-Israel?? Seen as too old ALREADY. Given this less than desirable array, Germans would probably prefer Mrs. Clinton as being the least disadvantageous to them. ![]()

Clinton vs. Sanders in IowaThe news from the Iowa caucus was interesting. On the GOP side, undesirable Cruz beat undesirable Trump. A choice between a rock and a hard place; the devil and the deepBut on the Democrat side it was neck and neck between Sanders and Clinton. So much so that SIX precincts were decided by the toss of a coin : Ames County, one Des Moines precinct, another Des Moines precinct, Newton, West Branch and West Davenport. Clinton won ALL six tosses. How likely is that? One chance in 26 = 1 in 64, about 1.6%. However, videos show that no precautions are taken against a biased coin, just a single toss was made. Is it possible to get a fair (balanced) result using a biased coin? Yes it is, by pairwise tossing as described below. Let's assume we have a coin that is biased 60% to 40% in favour of "heads". Then obviously a single toss is unfair. But if we toss the coin twice then the chance of two heads is 60% of 60% = 36%. The chance of two tails is 40% of 40% =16%. And the chances of Heads then Tails, or Tails then Heads, are 60% of 40% = 40% of 60% = 24% each. A fair and balanced result from tossing a biased coin twice. So we toss the (potentially biased) coin twice. If the same result crops up twice (H-H or T-T) then we discard that result and double-toss again (as often as necessary) until we get H-T or T-H. Say Sanders chose H-T and Clinton got T-H. Then a T-H result would indicate a Clinton win. As I pointed out, no precautions were taken against a biased coin :-( Maybe election officials in the USA do not have a sufficient grasp of elementary probability theory to understand my method, let alone explain it to Fox News or even the electorate. Math education is neglected in the US, methinks :-( So there we have it : Clinton and Sanders, a couple of tossers ;-) Comments (5) Monday, February 1, 2016
Around PI ;-)On his way to Stuttgart this morning, my friend Frank stopped off at the Mathematics Museum in Giessen (which we had initially visited 3 years ago) and sent me this photo of the PI wall via WhatsApp.![]()
So, by way of a reply, I messaged him that "circles are divided into 360°, but do you know why? They have something to do with PI too. So count off the first 359 digits of PI after the decimal point and look at the next three ;-)" If he does so, he will find that those three digits are 3 6 0 ! What a happy coincidence ( and a circular argument) ;-) |

It is also one of the six known truncated triangular numbers, because 1 and 15 are triangular numbers as well. It is a hexagonal number, meaning that you can distribute 153 points evenly at the corners and along the sides of a hexagon. It is the smallest 3-narcissistic number. This means it’s the sum of the cubes of its digits. It is the sum of the first five positive factorials. Yup, this is a 153-type blog. QED ;-) Books I have written
