Giving blood today, the first syringe was filled normally (plunger that's slowly pulled out to extract the blood). With the next, the nurse pulled the plunger out in advance, connected it to the needle, and the vacuum from the plunger pulls the blood out. Never seen it done like that before, thought it was really quite novel.


That's odd as for many years I've never seen a plunger, just a pre-vacuumed test-tube.

If one is diving so close to the limits that +/- 1% will make a difference then the error has already been made.

Yeah, all my blood tests over the last five or six years have used those vacutainer tubes.

Nurses are trained to use vacutainers. I don't bother with them unless I'm being assessed. They're only good if you have good veins. Using a needle and syringe is much easier, especially in patients with difficult veins or in those who are very unwell. It's also what I do when the nurses fail to take blood using a vacutainer. But it flies in the face of 'ealth'n'safety.

Making the Cars 2 required a render farm containing 12,500 CPU cores. On average, it took 11.5 hours to render a single frame.

:shock:

Didn't they just double the size oftheir render farm too?

Maybe they should look into GPGPU for their farms; or just borrow saspro's. :D

Today I learnt an awful lot about split tone processing. Or at least had my hunches confirmed. Feeling much more confident about my dark room practice. :)

Having decided to spend some time with my camera set to B&W, I was a bit miffed that Aperture imported the RAW files as colour images. Today, I discovered import filters... 8-)

Semantic Satiation - When you say a word over and over again until its meaning is lost.

Works particularly well with swear words.

The battery on my almost 4 year old laptop has a button operated, 5 LED, level indicator. :oops:

I could do with learning more about learning performance profiling, efficient algorithms and writing stored procedures, need to cut a 2 second page load to < 1/4 second ideally, managed to knock a second off by not using a poorly written graph control, but still in search of the other 1/4 second to achieve the goal
