Origami Helps Focus Mobile Phone Cameras

Picture-messaging phones may be about to get a whole lot more intrusive. Thanks to a novel way to make a thin sheet of a piezoelectric ceramic material work like an ultra-cheap micromotor, mobile phone cameras should soon be able to zoom and focus with the same precision as the autofocusing lenses used in expensive stills cameras

USB Learning Curve

I rebooted the computer today and it refused to power up again. Half an hour of unplugging, replugging, removal and replacement of box panels and much swearing later — all while working under a desk, amid a rat’s nest of cables with a Husky standing on my chest — I discovered the problem. When the Palm is sucking power through its USB cable, there’s not enough juice to power up the box. And conversely, the box tries to draw power from the PDA, so flat batteries on the Palm.

Probably worth noting that I’ve had little to do with USB until recently, as instead of the usual array of USB friendly peripherals I opted for the SCSI versions instead. And I’ve never had the Palm connected to the box when I’ve had to reboot.

After this encounter with the pitfalls of USB, I’m quite glad I opted for SCSI for the hard core peripherals instead.

Medical Marijuana Goes on Sale in Dutch Pharmacies

The Dutch are the first to permit cannabis to be legally dispensed to those with a doctor’s prescription, and other countries — including Britain, parts of the US, Australia and Canada, where plans for a similar system are at an advanced stage — will be watching the Dutch experience closely

Skin Can Be Stored For Future Use

American doctor Geoffrey Chernoff has told a Queensland medical conference that small skin biopsies are taken from patients and stored until the patient uses it for reconstructive or cosmetic procedures

MIT Roofnet

A few weeks ago, MIT graduate student Shan Sinha cancelled his broadband Internet service. Now his Net connection comes through the chimney. From a computer in the living room of his Cambridge apartment, a few blocks from the MIT campus, a cable goes into the fireplace up to the roof, where it is attached to an antenna. From there, data packets hop to another roof-mounted antenna at a nearby student’s apartment. That way, from roof to roof in multiple hops, Sinha’s data packets finally reach a gateway — a computer connected to the fixed Internet — at MIT’s computer science building

Spring!

Spring has arrived and things are flowering in the garden.

As I have a long line of plant murders in my past, I’ve narrowed things down to some of the tougher specimens. I’m also a big fan of foliage. I figure if something is only going to flower briefly, why have a crappy looking plant the rest of the year, hence the Irises and Cliveas with their strappy green leaves.

The luscious purple Irises came from my great aunt Marj.

The bright orange Cliveas hiding under a tree are from my Nan. Both far better gardeners than I could ever hope to be.
