I use a virtual studio, Poser. I push it and my hardware right to their
limits to generate high res files. I stuck with old fashioned methods not
using computers for serious work until recently. I mostly used a freeware
piece called Graphic Workshop since the early 1990s. It did a good job
with limited RAM. There was a DOS version. I had and used CorelDraw 11
for awhile, but now I find Paint and MS Photo Editor with enough RAM can
handle most of what I want to do. In commercial graphic work no matter the
medium making the copies the higher res the image you start with the better
the final result. Low information density is quite noticeable and looks
amateurish to a trained eye. Printing really suffers from this since the
dawn of the digital cameras. The newbies just don't have the old standards
for reference. Back in the day if you made a poster from a large format
camera photo you got a stunning result even with 125 line per inch
halftones. Subtle stuff for the eye is involved.
Oh wait I couple of points though. One fairly embarrassing, I made a
mistake on the size of the genome files. The big ones are in the range of
300 to 600 MB not GB! So doable on 2 GB partition. The trouble is some
sources deliver them in Zip format so you need enough space to hold the Zip
and unzipped file. 2 GB is still kinda tight depending on the
manipulations being done to file, copied with corrections or updates etc.
Its kinda nice and handy to have all your genome files in one folder and
that gets up into the many GB range. Like I said I'm trying to remove a
lot of the arcana and difficulty from bioinformatics for the biologists.
Simplicity and ease of use will be large factors in weeding out good and
bad apps for this discipline. My apps going OK. Put in a big night last
night. Writing a Windows app is a fairly big job for one person but you
don't have to waste a lot of time explaining what you did or keeping track
of what other people do like in a team environment. I may look at writing
a FreeDos version when I've got V 1.0 in the can. (yeah that sounds like a
classic opensource promise)
The other point... DOS had some notable shortcomings like no spell checker
and no pocket calculator emulator. Remember piping simple one off calcs
into GWBasic from the command line? I remedied the pocket calculator
emulator by writing one of my own in MS Quick C. I have the source code
and exe. It still runs under Windows XP. I'd be more than glad to
contribute it to FreeDos. I tried to pass this on to Eric when I first
signed on but he said this wasn't the right procedure. Its small stand
alone and non-TSR unlike Borland's. Who would I pass this on to for review
and considering including in FreeDos?
Thanks
