You're running Linux, eh?
My sympathies.
I run Linux (Fedora 4.0) and Firefox - and the PDFs pop up speedy and spiffy. It is a recent version, and does almost everything except cost a bunch. However, on my husband's bloated Microsoft machine, this doc took forever to load, compared to my swift lean little Linux-converted HP laptop. I programmed it myself, so it's my baby!
Just the facts from lil' ol' me...
As for shale/oil, and interesting aside: in my 1927 World Book Encyclopedia (my father was a book collector) there is an article about extracting oil from shale. My father first pointed this out to me during the oil crisis of 1973... at the time, it was not economically feasible, but the article noted that the techinique for this particular process would be developed "soon". I'm actually excited to see them finally taking it seriously. Thank you for posting this!
