The Panasonic Lumix G1 (also here on PhotographyBLOG) will be the first of the micro 4/3rds cameras, it will have a flip out 3 inch display (it looks like it is fully articulated and can be turned face in to protect it, yeay! this was a feature I really loved on my Canon G1) with a 460K pixel resolution (which still might not be enough for manual focusing). It has a very high 1.44 million pixel resolution viewfinder (so that might be enough to do manual focusing on, but I found that the 900K pixel view finder on the Minolta A2 was not enough for this so I am expecting this will will not be enough, however Panasonic is using a different technology which effectively stacks the RGB pixels so it might be a much sharper display than the traditional pixel count implies.). It got HDMI output too, so you can inflict painful hours of slide shows on your friends and relatives. Digital Photography Review has a preview of it here.
a = b + cwhere b and c are lists. But if you need to join a large number of lists together into a single list using the extend() function (of the list object) is much faster. In one rather extreme case where I needed to build an overall list of about 1 million points from individual lists that were about 400 points long, switching to the extend() function sped this up about a factor of about one thousand. So the faster code would be something like:
a =  a.extend(b) a.extend(c)
