Dreaming of Death
How do people of differing religions dream about Death?
Some of my blogreaders are Christians (Liz, Vic, Josef, Sarah etc), some Jewish (Ellison, Anthony, David), some Hindu (Amrit), some Buddhist or Islam, and a few fellow Atheists (Doug, yours truly). Their beliefs are something for their waking hours, but it would be interesting to know if and how religion influences their dreams, particularly of dying.
I doubt very much whether anyone - apart from pTerry - dreams of a Styx-crossing anthopomorphic Grim Reaper, unless some nuns dream in fear of him being dyslexic and dropping that first E. Or Buddhists , who presumably dream in a loop, transvestite Buddhists even in a Moebius loop ;-) ?
So send me your comments about YOUR dreams of Death and let's compare them :-)
Here are two of my - perhaps typically office-bound? - symbolic Death dreams :-
In the first dream, I was back in my usual office/lab scenario and going through the TODo (sic!) list in my diary. It was chock a block full of office meetings, lecture dates, customer lunches, product test schedules and releases, etc. etc. In my dream it was also a friday afternoon, so after crossing off things-achieved from my TODo list I flipped forward in the weekly diary as usual to see what I was supposed to be doing on the monday of the forthcoming week.
And lo!, all the pages were blank - nary a thing planned - for the remaining future. Even the dates fading away from the diary after a few days... :-(
In the second dream, I was out walking/hiking with many friends, mostly again from work, but also local villagers, cachers and biker friends. We were walking up a hill which became increasingly steep. My health and fitness not being what it was 20 years ago (I'll be 65 next month), everyone was increasingly drawing ahead as they chatted amongst themselves. Meanwhile I was alone, lagging more and more behind. They disappeared over the brow of the hill. When I arrived - breathing raggedly - at the top of the hill, they had all boarded the waiting bus and been driven off into the distance, leaving me alone, as the wind rose chillingly and darkness descended :-(
Much more morbid, that one. Now SWMBO - ever the optimist - claims these are like the dreams I had when going into retirement, but Thomas - ever the pessimist - thinks they are premonitions. We shall see , or not, as the case may be.
Now how do YOU dream about Death ? Ashes to Ashes perhaps ?

Pareto Charts revisited
Back in April, I gave you an introduction to Pareto Charts. Some of you sent some questions about their usage, so I'll try to answer those today.
Q1) "Why do you use Pareto Charts?"
Q2) "Chart by Count or by Cost or both?"
That said, you may need to draw two charts based on the same data. The chart on the left here shows that 41% of your problem cases are due to cause A (analysis by cause-count), and 18% due to cause C. However the cases may have different associated costs depending on the causes of the problem. The chart on the right here shows that 38% of your problem costs are due to cause C (analysis by cause-cost), and only 12% of your problem costs are due to cause A. So if your goal is to reduce problem-costs, you should tackle cause C first. See both chart examples shown here.
Q3) "Can you track your successes?"
For this I would use a 'before-and-after' Pareto Chart. Next to each of the cause-bars - in their original order - I would draw a bar showing the absolute counts (or costs) by cause AFTER your (partial) solutions have been applied. Do NOT use percentages on the vertical scale here! You can easily see what solutions worked. Yes, I do know that you should do a Chi-squared test to see if the change is statistically sgnificant, but that's material for another blog entry on another day. Let's keep this simple today :-)
Q4) "What if there is no 'one' solution to the problem's major cause?"
In this case you may need to analyse the main cause further, breaking it down into sub-causes, each of which may be tackled by its own partial solution. See below :-
Q5) "Isn't this an awful lot of work?"
As long as the cost of the analyses (before and after) plus the cost of applying the solutions is less than the lack-of-quality costs of the original problem, you're on a winner, reducing costs overall. Training costs are minimal, just read this blog :-)
Satire-day, May 16, 2009
Now, Regula readers of this blog will know me as an Atheist, a position shared with any number of (more famous) people. That means that we do not believe in the existence of sundry fictions like Jahweh, Allah, Jesus, Mary, Jupiter or Thor.
For purposes of parody however, some of us do purport to believe in the FSM, the Flying Spaghetti Monster ;-) FSM was invented in 2005 by Bobby Henderson as a satirical protest to the decision by the Kansas State Board of Education to require the teaching of intelligent design (creationism) as an alternative to Darwin's biological evolution in Kansas public schools. In fact, this Pastafarian pseudo-religion does have some good ideas. In place of the judeo-christian ten commandments, it contains the Eight I'd Really Rather You Didn'ts. Go read 'em, they make more sense than (say) some of Islam's not-so-great ideas, like jihad, honour murders, and female circumcision :-(
Regular blogreaders will also know of another hobby of mine, Geocaching. Geocachers look up the coordinates (latitude/longitude) of hidden caches in an internet database, then go off hiking with a portable GPS to try to find these caches. Sometimes the caches contain Travel Bugs (TB) or GeoCoins, each having its own individual purpose and destination, declared in their database entry.
And so it must have been Divine Intervention that led me to find this FSM GeoCoin ;-)
The FSM GeoCoin was started in Munscheid (near Bochum, Germany) by Bonsai Cacher in October 2008,
to whom thanks :-) It has so far travelled 540 kms from cache to cache,
being photographed with a plate of noodles**
at each stop (as Bonsai Cacher requested). So I had noodles for lunch today,
The fossilised fish on the back is a Darwinian hint about evolution, visually punning on the Creationists' ichthys symbol ;-). Thanks for the amusement, Bonsai Cacher :-)

A tale of Three GreensNeither is this a tale about vegetarian diets, nor is it about an extremely short golf course. It is a tale about aviators.
There are two kinds of pilots : those who have landed a retractable-gear plane wheels up and those who have NOT ... yet.
The Cessna 210 shown on the left bellied in last month at Dortmund airport. This is why we pilots have three green lights to show us 'gear down and locked' and checking for three greens is part of our pre-landing checklist. Even when flying alone, I still recite the checklists out loud. YMMV.
But I remember an unfortunate incident at Ahden airport a couple of decades ago, because I was the duty flying instructor that day and was first at the scene of the accident. A ferry pilot had picked up a brand new aeroplane from the US factory and flown it non-stop across the Atlantic to land in Ahden (the rear seat having been replaced by large ferry tank). He had landed it beautifully, greasing it on straight ahead and taxied it onto the apron to hand it over to its proud new owner.
Said proud owner refuelled and took his gleaming new ship (only 12+ hours ferry time on the clock) for a test ride. Turning final, he lowered the gear (I SAW it come down), called 'three greens' and landed, crabbing slightly into the cross-wind.
Toc, Toc, toc, the ominous sound of propellor blades hitting the concrete, screeeeech. I was out of the door and running for the runway pausing only to grab the big fire extinguisher. The landing gear had collapsed on touchdown despite three greens!
I was told that the LBA accident investigators found that there were NO locking pins in the undercarriage when the plane had left the factory! The professional ferry pilot had landed on all three wheels at once, very smoothly, straight ahead, so the accident didn't happen to him. But the owner had had to crab left slightly into the crosswind, the left leg touched down first and - being unlocked - had folded, shortly followed by the right main gear as it touched down askew. Brand new plane too :-(
But the owner didn't know about the missing locking pins and so thought HE had screwed up the 'three greens' call on his very first retractable landing. Luckily no-one was hurt, but I imagine the owner cannot eat a vegetarian meal to this very day ;-)

Check Mat :-(
Please check that you have an adequate supply of beer mats (or coasters, as the 'merkins call 'em) because the Katz Group of Weissenbach, Germany has filed for bankruptcy! Katz made 70% of the beer mats worldwide, selling mostly to breweries who then provided them as 'free' advertising to bars and pubs everywhere. But when the breweries started cutting costs to improve their margins, beermat sales (8c/mat) declined. So we can expect a shortage soon. Then we can no longer keep the children amused in the pub by having them build a beermat pyramid. No longer can we flick them* over the bar into the topless barmaid's cleavage (o)|(o). No longer can we sketch out our world-breaking ideas over a quart of the foaming ale :-( . How shall we now level the wobbly tables in the beer garden?
And what shall we do now for flippin' pub entertainment ? Check Mat, indeed !

Geocaching 108 : Best of the local cachesMid-April I mentioned a PB/DT geocachers' get-together. Lots of experienced geocachers there, so I mailed them asking for tips for the most spectacular cache locations within 100 kms of Paderborn. Here are their kind replies (in chronological order of reply), whereby I have removed the duplicates :- All these links lead to cache descriptions which are in German, so if you can't read the language, you may skip today's blog :-)
So let me thank all of these folks. Now I looked up the lat. and long. GPS coordinates of all of these, and the direction and distance vectors from my house. Sorting by direction should then give me a reasonable sequence in which to visit them. Yes, I DO know the travelling salesman problem is NP-complete ;-)

Dining tip : La Maison du Chocolat in Potsdam :-)
I am showing you these photos just to get you slavering with envy ;-) Just last month we visited the picturesque town of Potsdam - just outside Berlin - the town of beautiful buildings and palaces like Sanssouci. Now here's my (no longer a secret) dining tip: Once you have seen the palaces etc, go to the old Dutch quarter (Holländischen Viertel) and stroll down the main street with its typical period redbrick frontage. On the main crossing you will find La Maison du Chocolat - the House of Chocolate. The picture on the left shows you the covers on the wicker furniture on the terrace, as an identification aid in the unlikely situation you might need help ;-)
Their Speisekarte menu is short but the food is spectacularly good for what is basically a street cafe´. I started with a soup of fresh mussels with potatoes and coriander flavouring. My main course was a corn fed chicken stuffed with slices of lamb on a bed of avocado. After a digestive break, I went to look at the dessert counter :-)
Such a spectacular array and variety of different chocolate cakes! I was dribbling just looking at them :-) But the slices looked so huge after my first two courses that I ordered the attraction of the house, a selection of three home-made chocolate ice creams, each tasting so very different & each better than the other if that's possible!
Their address is :- La Maison du Chocolat Restaurant & Café, Benkertstr. 20, in the Holländischen Viertel of Potsdam. Telephone 0331/237 07 30 - Fax 0331/201 04 99

MAYDAY : The dea(r)th of creativity :-(Blogger's block : a lack of new/any ideas of anything to write about :-(
I need some way of turning my creativity back on. Any suggestions are welcome.
OTHER people can make neat Xmas woodcarvings. I cannot, I have no such talent.
OTHER people can make photorealistic paintings. I cannot, I have no such talent.
OTHER people can make amusing, if kitschy, pottery. I cannot, I have no such talent.
I'm currently limited to little bit of German-style village-housewife ikebana, soothing to the soul; some uninspired macro-photography, nothing up to Flickr standards; and recycling used spark plugs, washers, and stainless steel shims with a soldering iron ;-)
I must have written about 1200 blog entries over the past 6 ¼ years, see above.
But I appear to have run out of steam on the writing front, and this damn computer is no help at all! Let's just look at some of the 'creativity-aids' software on my desktop:-
Back when I was doing Artificial Intelligence research, I once wrote an AI program to generate new ideas for patentable devices. It did means-end-analysis. You told it what the end result should be and told it what component parts you had in stock. Then it would run through the combinatorial explosion of achieving the desired goal from the given parts, discounting any existing (patented) devices in its database. The remainder would be a set of 'new ideas', sorted by cost of parts if that was less than existing solutions. The human partner would then check these 'new' ideas for viability, since the AI-bot was not allowed to patent stuff itself ;-) See my introductory textbook Savory, S. "Grundlagen von Expertensystemen", Oldenbourg Verlag, Munich 1988, ISBN 3-486-20757-1, for a much simplified version of the basic idea. Not really useful :-(
How ironically self-contradictory today that I am writing about NOT writing ;-)
So there will now be a (short?) intermission :-(
Comments (11) :
Crouchender (London,UK) writes :
"Surely it is better to have a few good articles, and yours invariably are,
rather than a daily drivel as many other blogs seem to be.
You have a good mix of topics and intellectual content, and perhaps you should be content
to have a break whilst the rest of us are still struggling on some of your more difficult [to me] presentations."
Pietr (Moscow,) writes :
"Tell us more about that Pareto stuff and other TQM tools, as you did last week.
If you can keep it that simple, we'll all profit :-)" I'll try, Pietr.
Sarah (Rotoruoa, NZ) puns : "...ease your emergency by writing about 3 loaves of french bread" ; Pan,pan,pan : I geddit, Sarah; but wouldn't that be loafing about? ;-)
Karl-Heinz (Stuttgart, Germany) wants "...more in the geocaching series." Wilco.
Jenny (Ibiza) suggests "...just give us more pretty photos until you come up with some text!"
Good idea, Jenny, that'll tide me over maybe. Wilco.
Gudrun (Schweinfurt[sic!]) sez "...something about the swine flu pandemic?"
Pergolator suggested "...You could do a whole article on techniques employed to create your spark plug aeroplane.". Not my original idea, Charles, inspired by a 1970s professional construct. Just look at the photo and you too can see how it's done.
Klaus (Alaska) sent me inspiration in the form of several photos of model motorcycles built from recycled watches (like this and this), artist unknown. Too hard for me, Klaus. Besides, I'd prefer to spend my time building a REAL bike, like this NorVin :-)
Bettina (Stuttgart) points me to this New Scientist article.
