Comment No chance (Score 1) 221

As others have said, you can not get accurate speech recognition for multiple speakers. Even for the best of breed closed source software (Dragon) you also need to have good control over microphone quality and placement, and the technique in this instance is to shadow the speakers (put them on headphones and speak into the microphone). transcript.el will remove some of the pain points for transcribing for you if you're happy using emacs. It works out as cost/time effective - I reckon it takes transcription time from 5-8x the length of the recording to something like 2-3x the length, but at this point in time you're not going to find a satisfactory open source solution to machine transcription, either shadowed, or from live tapes.

Comment Re:Wow (Score 1) 303

There are a couple of products in this niche - one in the Panasonic Toughbook range, and one from a company called Motion Computing (a startup from ex-apple staff). The Motion device is the better product, but they're both pretty similar.

But both of them are keyboardless devices running Windows XP Tablet edition, and frankly that sucks - a multitouch integrated UI specifically designed for keyboardless environments (not just bolted on like windows tablet) is really needed to make these things work proprly. I had wireless reliability issues (suspend resume problem) on the Toughbook I tested.

So yeah, I reckon a mooted Apple tablet with a ruggedised case (with a built in handle - this is important) may well be the way to go with this for now.

Comment Some nice data for you (Score 2, Interesting) 489

Here is my nice chewy data on climate and temperature stuff that I'll add to, with analysis as time allows and people find data for me.

My conclusion so far: it's very unlikely not to be co2 responsible for most of the warming we've observed since the 70s, it's likely to get much worse, and there don't seem to be any viable alternative explanations.

Comment From a real physics teacher (Score 1) 364

My wife (who is a physics teacher who has taught electronics) says the following:

Dick Smith (if they are in the us, maybe something similar) sells kits with full instructions. they need to be soldered, but year 9s should be able to do this - I had year 8s solder successfully. they will need to be reminded of first aid treatment for burns first. they can build light detectors, movement detectors, radio recievers, sirens, simple electric pianos etc.

Comment Compter illiteate & overstretched staff more l (Score 5, Insightful) 294

(Disclaimer: IHAPSITF - I have a PhD scholarship in this field).

In most healthcare systems, staff are very busy, and computer illiteracy is rife. To get good with these electronic systems you've got to use them constantly, and when half the staff or more don't understand why they're doing a particular thing in a particular way. There's also a workplace culture of written notes, and often a limited number of computer terminals per staff member. So with queuing for terminals, fairly high friction processes for retrieving data and so on and so forth, there are quite high barriers to entry from a human point of view.

Don't get me wrong, EHRs have potential, and can reap benifits (especially for management - they can also make floor staff's job harder). Some kind of robust iphone-like device which is a secure platform for data entry and retrieval, might make it sufficiently easy and efficient from an end-user's perspective to decrease implementation barriers.

Submission + - Ecommerce with Catalyst - a post-project analysis

Denny writes: "Perl is Alive has published a 'six months later' analysis of a Perl ecommerce project which used the popular Catalyst framework at its core. It's a well-written look at how, by choosing various components from CPAN, you can build up a complex custom-tailored system without having to write everything end-to-end yourself. The author concludes that they would "undoubtedly" make the same technology decisions again, given the success of this project, and the quality of 'modern' Perl libraries and frameworks which are now available from CPAN."
