Paper Polyhedra

January 28, 2008 at 8:18 pm (interesting, odds, science) (, , , , , , )

If you like making things and like maths, then this site is for you. It has loads (over 100) of paper ‘nets’ for printing out to make the models. It contains the platonic solids, archimedean solids and many other regular polyhedra.

Fancy a challange? Try the Rhombicosidodecahedron or how about a Small Ditrigonal Icosidodecahedron? Actually, I quite like the Snub Dodecahedron.

M C Escher for Real

January 18, 2008 at 8:44 pm (interesting) (, )

Whilst wandering around the Internet, I came across this site.  Amazing stuff.  This chap makes physical models that produce some of the optical illusions of M.C.Escher.  He’s also done some other models taking the M.C.Escher ideas even further.

Fantastic.

Laptops for Africa?

January 14, 2008 at 9:10 pm (computers, interesting) (, , , )

BBC News 24 had a report over the weekend about the One Laptop per Child (OLPC) project.  They interviewed people at a pilot school in Nigeria about what they thought about the laptops.  Generally speaking, everyone was very impressed.

They also visited another school that is Intel’s showcase for the Classmate PC project – another initiative with similar aims to OLPC.  Again, feedback was generally very good.

It was an interesting contrast seeing the two projects together like that. OLPC, the charity, with the $200 special machine running Linux and other open-source software vs the commercially backed, $350 Windows machine.  Its a shame the initiatives couldn’t be combined a bit more but the drivers for the two projects do seem very different.  The OLPC project really seems to aim for empowerment – using hardware and software that people can learn about and ‘get inside’.  The children were also able to take them home and share them with their families.  The Classmate on the other hand was locked away at the end of the day, and seem to work on the principle that ‘if we are going to give them laptops, then give them ‘normal laptops’ like everyone else uses’.

The report ended with an interview with someone in the Nigerian government.  He was basically telling us about his difficulty – does he spend $100m on laptops for children to invest in their futures or does he worry more about providing a roof and food to help people in the ‘here and now’.

Interesting projects raising interesting issues.

Action on CO2

January 13, 2008 at 5:00 pm (house, internet, security) (, , )

Those adds with the funny engines on wheels have been quite prevalent recently. One thing that struck me about them, is that they end saying something like ‘search for Action on CO2 online’ rather than give a web address, which I considered odd.

Well, the carbon calculator page is http://actonco2.direct.gov.uk/ (as far as I can tell), and I think that the actual site that tells you about the initiative is http://www.direct.gov.uk/en/Environmentandgreenerliving/actonco2/DG_067197.  Neither of these appear in any of the first page of search results for ‘action on co2’ in google.  Looks like http://www.actiononco2.com has been cybersquatted by someone.

This could be a good scam for someone – get a site, use all the search engine tricks you know to get it high up in the ratings for results for searching on ‘action on co2’ and anyone who follows the advice from the government ad on the telly will end up at your site, downloading whatever you choose to put on the main page.  Hmm…

With a URL like the ones above, I can see why they perhaps didn’t want to put it on the ad, but to just say ‘search online’ seems like a mistake to me ….

4500 Amps

January 12, 2008 at 10:17 pm (interesting, moan) (, , )

There was one of those ‘top 10 roller coaster‘ type programmes on, I think it was, Sky 3 (freeview) the other day.  One of the coasters they showed was a large U-shape, with the car being shot up one arm of the U, coming to a halt near the top and dropping back to go up the other.  The car was powered by a linear motor, which the designers said uses 4500 Amps each time the car is launched.

Thats right, over 100 times the current rating of an electric shower.  10000 times the current of a 60W light bulb.  Ok, its probably for quite a short space of time, but when you think of all the talk of trying not to leave things on standby because of the power they use … and compare that to 4500 A a go, then it makes you realise quite how much effort (and environmental impact) goes into keeping people entertained …

“Little Lady” – “The Shrimps”

January 2, 2008 at 10:28 pm (music) (, , )

Whilst on the subject of lyrics, this was one track I was searching for. I couldn’t find the lyrics online, so ended up listening hard and typing them in. In case anyone else is interested, here they are (I think).

Little Lady – The Shrimps

On my knees, can’t you see, what you do when I see that little smile.
Won’t you please be my girl don’t you know that you’re driving me wild.

Pretty woman I love you, yes I do.

If you wanna do it little lady, come and dance tomorrow,
If you wanna boogie with me baby, come and dance tonight.
If you wanna do it little lady, come and dance tomorrow,
If you wanna boogie with me baby, come and dance tonight.

Guess it shows on my face that I’m shy but I gotta say the words
yes i know what to say gotta try gotta make my feelings heard.

Pretty woman I love you, yes I do.

If you wanna do it little lady, come and dance tomorrow,
If you wanna boogie with me baby, come and dance tonight.
If you wanna do it little lady, come and dance tomorrow,
If you wanna boogie with me baby, come and dance tonight.

On my knees, can’t you see, what you do when I see that little smile.
Won’t you please be my girl don’t you know that you’re driving me wild.

Pretty woman I love you, yes I do.

If you wanna do it little lady, come and dance tomorrow,
If you wanna boogie with me baby, come and dance tonight.
If you wanna do it little lady, come and dance tomorrow,
If you wanna boogie with me baby, comeand dance tonight.

Online Karaoke

January 2, 2008 at 10:23 pm (interesting, internet, music) (, , , )

Whilst searching for some lyrics online, I came across this site – Ronan’s Online Karaoke. It has a wide selection of tracks with lyrics and simple accompaniments.  What was interesting to me, is that the tracks are mostly in MIDI format – which means you can load them into your favourite sequencer and start playing around with them – even seeing notation.  Cool.

Electronic Gadget Blister Packs

January 1, 2008 at 9:48 pm (moan, odds) (, , )

Recently, it seems that more and more electronic gadgets come in blister packs, sealed around all four sides. Not sure when the trend started, or why this is felt better to deal with than what we used to do before … but why are they so flipping awkward to get into? You end up having to cut around two sides and then try to get the internals out without slicing your fingers open!

Of course, being January, we’ve had our fair share of plastic packs to open over the last week. No doubt they will all end up in land-fills too (the council only recycle bottles). Well, hopefully thats it for a while – we’ve had our quota for now.
