sudoku : when only one trivalue remains, there is not necessarily a BUG+1

The object of this post had been to prove that when there is a single trivalue, then one of its candidates ocurs exactly three times in its 3 units and that this is the true candidate.
However here is a counter example from link : where G6 is a sole trivalue without any of its candidates leading to BUG.

5 4 67 | 23 9 26 | 8 37 1
3 9 2 | 14 17 8 | 67 5 46
78 1 68 | 35 67 45 | 39 2 49
-------------+-------------+------------
78 3 4 | 6 18 17 | 5 9 2
6 2 78 | 59 4 59 | 1 78 3
1 5 9 | 27 28 3 | 67 4 68
-------------+-------------+------------

Little known facts

From this site these gems (amongst many) :

  • The largest number whose name does NOT contain the letter "n" is EIGHTY-EIGHT.
  • ZENZIZENZIZENZIC (eighth power of a number) has more Z's than any other word in English. The word is in the OED. It was suggested by Robert Recorde, 16th century writer of popular math textbooks, although in his spelling the last letter of the word was k.
  • Words spelled with a number of letters equal to the number itself :
  1. Maori : KOTAHI TEKAU MA ONO (16)
  2. Zulu : ISHUMI NESIHLANU (15), AMASHUMI AMABILI NA MBILI (22)
  • Shortest French pangram : "portez ce vieux whisky au juge blond qui fume."

web 2.0 tools

text directly from this interview


What tools do you use out there on the web that you find useful? Are you a devotee of any of the "Web 2" tools?

One can think of the Web as a place where multiple overlapping global conversations are taking place simultaneously. To keep up with these conversations I have established my online home at Netvibes, which allows me to integrate almost all of the tools I use and organize them into different “tabs” in a way that fits with my online life. I have a tab for blogs and comments which allows me to track multiple online conversations, along with a blog search module that updates whenever somebody posts something related to the topics I am currently interested in.

To keep up with parts of the global conversation that might not have a simple RSS feed, I use feeds from social bookmarking services like Diigo and Del.icio.us. As a visual anthropologist I also need to monitor parts of the conversation taking place in photos and videos. Sites like Flickr that allow photo tagging make it easy to monitor the photos, and with new video services like Viddler, Mojiti, and Bubbleply that allow users to tag, comment, and create their own content within and on top of existing videos, it will soon be possible to be alerted the moment somebody uses a tag to describe any particular piece of an online video. On the other end of the media spectrum, it is now easier than ever to keep track of traditional paper-based journals as well, as many are now providing RSS feeds and putting the articles online. This has created tremendous potential for Cite-U-Like, a social bookmarking service for academic journals, which I use to alert me whenever somebody uses a certain tag, or when somebody with similar interests as me tags anything.

The best tools are those that are flexible enough to be used beyond that for which they were intended. The more a web service can build this kind of flexibility in, the better, as it can tap into the collective intelligence of those using the service to extend its possibilities. Netvibes has this built right in by allowing users to create their own modules. With the help of an “API maker” like Dapper, we can create almost anything we need and integrate it into Netvibes, further extending our ability to keep track of those parts of the global conversation that interests us the most.

As a university professor I have also found Facebook to be useful. I was inspired to use Facebook for teaching by something I saw while visiting George Mason University. Like many universities, they were concerned that the library stacks were rarely being accessed by students. Instead of trying to bring students to the stacks, they brought the stacks to the students, placing a small library right in the middle of the food court where students hang out. We can do the same with popular social networking tools like Facebook. Facebook is not only great for expressing your identity, sharing with friends, and planning parties, it also has all the tools necessary to create an online learning community. Students are already frequently visiting Facebook, so we can bring our class discussions to them in a place where they have already invested significant effort in building up their identity, rather than asking them to login to Blackboard or some other course management system where they feel “faceless” and out of place.

food for thought

seen in a posting to a blog

He quotes Chris Bowers of MyDD whose perspective is political blogging not academia, who writes, " After two and a half years of virtually non-stop blogging, my perception of myself as a distinct individual has dramatically waned. My interior monologue has virtually disappeared. I no longer have aesthetic-based epiphanies, and I almost never concern myself with examining internal passions or emotions anymore. Blogging has not just changed the activities in which I engage--the activities in which I engage in order to be a successful blogger have profoundly altered the way my mind operates and the way I conceptualize my agency in relation to others. In effect, I do not exist in the same way I once existed."

Rien n'est possible sans les hommes
Rien n'est durable sans les institutions

for those who have doubts about the word social

taken from a comment to a post on a blog ("scobleizer") :

  1. This reminds me of an old discussion about social software.
    Friedrich Hayek famously said that the word ’social’ empties the noun it is applied to of their meaning. Hayek goes on:
    “it has in fact become the most harmful instance of what, after Shakespeare’s ‘I can suck melancholy out of a song, as a weasel sucks eggs’ ( As You Like It , II, 5), some Americans call a ‘weasel word’. As a weasel is alleged to be able to empty an egg without leaving a visible sign, so can these words deprive of content any term to which they are prefixed while seemingly leaving them untouched. A weasel word is used to draw the teeth from a concept one is obliged to employ, but from which one wishes to eliminate all implications that challenge one’s ideological premises. “

Whether in business, science, politics or the arts,
some men, says Simona James, simply theorise
passion out of their hearts

How come atrocities may be forgotten
but one stabbing remark
will haunt the heart forever ?

If it's true that where there's muck there's money
it's also true that the rambling bee
brings home the honey

The people I love the most, says Granny Arden
are those who live and love the moment
and don't blame now for not being then

I've heard it in the chillest land

What is this life if, full of care,
We have no time to stop and stare?

No time to stand beneath the boughs
And stare as long as sheep or cows.

from Leisure by W.H.Davies

I've heard it in the chillest land
And on the strangest Sea -
Yet, never, in Extremity,
It asked a crumb of Me.

study of a lion track


Early morning August 2005 near Nossob camp in the Kgalagadi Frontier Park, I came across what was clearly a lion track. Yet my guide book on the subject only showed the lower part of the photo as being a lion track : the pad of the paw. So what was the other part ? It turns out that when lions charge their claws (normally retracted) are extended.
This track therefore was evidence that in the quietness of the previous night all was not so calm.

chobe






Scenes from Chobe in Botswana; what's known as a river safari. You find a boatman and either go out as in group or solo. And before long herds of elephant are on the banks or crossing the river to an island in the middle. Before your very eyes. Mere yards away. The boatman was cautious, make no mistake. And he certainly wasn't merely yards from the hippo ! Great care must be taken with these animals who hold to their space. My route to Chobe began at Katima Mulilo which is the border town on the eastern end of the Caprivi strip, the Zambezi marking the frontier with Zambia. The name had appealed to me ever since I first heard it and was determined to begin a trip to Namibia from there. Good decision !


gemsbok changing gears


according to my calculations the oryx on the left won the race in a photo-finish...an everyday scene at a waterhole in etosha where the gemsbok (aka oryx) never fail to liven things up; the zebra, girafe, wildbeeste march in from all parts at a sedate pace; as do the gemsbok (second photo) until the mood takes them to change gears; obliging the impala to take evasive action.

lion searching for daniel






an abiding memory of a morning in etosha : a herd of wildebeeste (gnu has a more interesting etymology being derived from the khoikhoi word itself being onomatopaeic for the grunting sound the animal makes) moves slowly in single file across the pan, then has a joyous outburst with the flying dust caught in the morning light; out in the distance - mere black dots - are ostriches, and nearby is the injured but magnificent lion seen in the second photo.
