Mount St. Helens

Thursday, September 30th, 2004

As the chance of a new eruption at Mount St. Helens increases today, Shelley Powers has posted her recollection of living downwind of the previous eruption on May 18th 1980. Makes interesting reading – and makes you wonder what on earth it will be like if Yellowstone Park erupts (the last eruption there was 3000 times the power of the 1980 Mount St. Helens eruption).

IMF says UK house prices too high

Thursday, September 30th, 2004

The International Monetary Fund yesterday added its voice to that of The Economist and The Bank of England, pointing out that British house prices appear much higher than can be explained by developments in fundamentals (wages and rents), and warning:

The central risk remains an abrupt adjustment in the housing market… ...With interest rates on a rising trend, and most house purchases financed with adjustable rate mortgages, house buyers should exercise particular caution at the present juncture.
The government, estate agents and building societies have been talking down the risk of a sudden drop in house prices, but as The Economist has pointed out previously, the first law of bubbles is that they inflate for a lot longer than anybody expects. The second law is that they eventually burst.

Modelling impossible Escher pictures in 3D

Tuesday, September 28th, 2004

Most people will be familiar with Escher’s impossible pictures depicting water perpetually flowing downhill in a closed loop or triangles which appear to join up opposite sides. Gershon Elber has discovered that some of these impossible figures can be made as 3D objects – the optical illusion only works from a specific angle, however. He has made some short videos of the models being rotated, so you can see how the illusion works.

Ireland cuts phone lines to stop scams

Friday, September 24th, 2004

Irish telcos were refusing to refund bills of up to $22 000 run up by unsuspecting computer users who had loaded trojan dialer programs to their computers and ended up routing their internet surfing via places such as Tuvalu, Diego Garcia and Mauritania for prices of up to $7.50 a minute. Now the government has stepped in and cut off direct-dialed calls to entire nations, in order to stop internet-based fraud.

Calls to 13 locations world wide will now have to be routed by operators who will check that the calls are being placed to humans, rather than to modems. Legitimate numbers will be placed on a white-list which will then allow further calls to be direct-dialed.

Could this result in a game of cat and mouse – I wonder how long it will take before the white-listed numbers get reconfigured by the fraudsters to route through to the money-making computer connections?

Walking helps prevent dementia

Wednesday, September 22nd, 2004

Elderly men, who walked less than 1/4 mile per day were found to be nearly twice as likely to develop dementia as those who managed two miles a day, an article published in the Journal of the American Medical Association reports today.

As a reasonable amount of exercise (say 1/2 hr per day) also helps keep your blood values in order (sugar, fats) and is supposed to ensure that you are less likely to develop cancer or coronary disease, (for more on the benefits of healthy living, see also this item on the BBC web site), I guess there is nothing for it, but to brave the elements (it is pouring outside) this evening. On the way out, I can look at our freshly renovated pond, which is now threatening to overflow any minute into the next door neighbour’s garden because the overflow pipe has suddenly blocked. The weather forecast is for more rain in the next 24 hrs. We have ordered a visit from the local drain-clearing specialists tomorrow morning.

Memo to self – never buy a pond with the house ever, ever, again… In fact, never again buy a pond, with or without house.

Flying a kite

Tuesday, September 21st, 2004

If you have an old digital camera knocking around and fancy using it for some aerial photography, take a look at this article in engadget.com about taking pictures from a kite. If you can wield a soldering iron, it looks fairly straightforward, apart – possibly – from landing the camera intact afterwards.

Tough liberalism

Monday, September 20th, 2004

The British Liberal Democrat party is proposing to send teenage joyriders to go and race cars or learn car maintenance, as well as fining them £40. The proposal is called “tough liberalism” by the party spokesman.

Um – is that supposed to be a deterrent or an incentive to break the law?

Glass muesli bowlGlass muesli bowl

If you see glass muesli bowls like these – they were sold as Villeroy & Boch, but we can’t find them on their web site and they have no identifying marks – and intend to wash them in a dishwasher, then don’t buy them. We have had three bowls crack, like the one above, in as many weeks. We haven’t dropped or mistreated the bowls in any way.

They come in various colors – the commonest is the white / red combination shown here, but they also come in yellow with black rim and with lime green and blue bodies (I can’t remember what color rims).

How good is your spelling?

Thursday, September 16th, 2004

Ruth and I both tried this spelling test in the Guardian. I confess, we both got 13 out of 23. Any of our friends or readers who can beat that – without cheating?

Single processor Apple G5 sleeps again

Tuesday, September 14th, 2004

Apple have issued a patch to the G5 uniprocessor firmware, which I have applied. My G5 now sleeps again without the fans running, which is a big improvement.
