Dementia 'losing out' to cancer in funding stakes

Today, I came across the article Dementia 'losing out' to cancer in funding stakes in the Health section of the BBC website. The article starts with stating: I think that the article makes a very clear analysis of the problem. The contents of the article does not surprise me at all and affirms my suspicions. I think that the situation is not much better in any other country in the world. (Alzheimer's Disease is the most common cause of dementia.)

Four Colors Suffice

This afternoon, at 16:56:10, I bought the book Four Colors Suffice by Robin Williams for € 14.95 from bookshop De Slegte. In the evening I started reading this book. When I showed Annabel the fake counter example by William McGregor, she immediately wanted to solve it, but failed to do so.

Four Colors Suffice

Today, I finished reading the book Four Colors Suffice by Robin Wilson, which I started reading on February 6, after I bought it on the same day at 16:56:10 for € 14,95 from bookshop De Slegte. I enjoyed reading the book, although I have to remark that where Wilson takes great care to explain many rather trivial mathematical facts in the first chapters, this lacks in the latter chapters where the mathematical details become more and more complex.

Dancing snow flakes

The whole day small snow flakes were falling from the sky. Especially during the afternoon, when I was laying in bed with the flu, I watched how the snow flakes where dancing along the window, as the wind would often lift them up or make them float along the window. In the early morning and late in the evening some of the snow did stay, but during the rest of the day it was just a little to warm for doing that.

This morning, there was a lot of snow in the West of the country. Here in the East, it started to snow later, and when it started to snow here at first did not stay, but later it did. Around the time Andy usually arrives at home from day care we were phoned that he was still there and that the taxi was delayed due to the snow. It was only an hour later that he finally left and he arrived about two hour later than usual.

Dylan on Dylan

This morning, I finished reading Dylan on Dylan in which I started reading on December 30 after I bought it on December 29 at 17:37:29 from De Slegte for € 2.50. The book contains 31 interviews with Bob Dylan taken from 1962 to 2004 and thus cover a large part of his life. Some interviews are interesting others are boring or even very vague, such as the one about his film Renaldo and Clara. In most of the interviews you see that the interviewer is wrestling with his questions and/or that Dylan is answering the questions in his own manner. In many ways it is clear that Dylan is not easily distracted and is independent of what other think about him. In a sense he comes to me as a rather enlightened personality living in the here and now, and not to much thinking about the past or dreaming about the future.

Nonogram solvers

This evening, I came across Survey of Paint-by-Number Puzzle Solvers. Paint-by-number puzzles are also called Nonograms. In the past years I worked on several solvers myself, and I believed that I did have quite a strong solver. I downloaded the set of 5000 random 30 by 30 puzzles (linked to in the survey) and tried them on the various programs I developed only to discover that my solver is not very fast and that there is still a lot of room for improvement.

Uru online

This afternoon, I downloaded the free version of Myst Online. I tried it out a little than, just to check if it installed correctly. In the evening, I played the game for the first time. It very much looks like stand-alone version of Uru, which I played before. It does contain some new ages (worlds). You have to replay all the ages again. I already did some of it. It is funny how much you remember. It is almost like revisiting a city you went to years ago. For some details, see the logbook I am writing.

Wireless router

This afternoon, Annabel, Li-Xia and I went into the city to look for a wireless router for Annabel to be used in combination with her netbook and het Ipod touch. We first went to Media Markt. They really had made a mess of their wireless section. After searching we only found two wireless routers that we might consider to buy. The cheapest was Netgear N150 for € 39.99. Next we went to Paradigit. They had a Sitecom and a Linksys wireless router. Next we went to Dynabyte. There they had the same Linksys wireless router, but it costed about 10 euro more. Although Linksys is know for its beter quality, we felt that the Sitecom wireless router with 300N was better than the Linksys of the same price. At 15:12:15, I bought the Sitecom Wireless-N 2.0 Router WL-341 v3 for € 39,99 from Paradigit.

At home the first question was how to wire it up to the rest of our network. At the back it has one blue socket and four yellow sockets. The blue socket is meant to be connected to your ADSL monitor. But we already have a Sweex network router with build in ADLS modem. First I connected a network cable from this router on one of the yellow sockets, but I could not figure out which IP address to use. I also expected a conflict between two DHPC servers on both sides of the cable. Next I connected the cable to the blue socket and tried to connect to it, but that too did not work, which did not really surprice me. Finally, I connected the netbook with the short blue cable that came with the wireless router on one of the yellow sockets and was able to configure it. However, when we tried to make a wireless contact with her Ipod touch, it did not work. I changed the key on the rooter, but what we tried did not work. I searched the internet for more information, but was not able to solve the problem. I let the problem rest for some time and read some more manuals. When I tried the next time, I decided to change the key in something with all capitals, and then it suddenly worked. I spend some more time to configure the ACL with the MAC addresses of netbook and the Ipod touch. These kind of things always take more time than you would expect even for someone who has a degree in computer science.
