bash - sort -g not working as expected for exponential notation -


from awk script output list @ bottom of post, , i'd sort numerically on first column. since it's in exponential notation, tried sort -gk1,1, didn't work - output in listing.

what problem here? thought -g able handle exponential notation?

i have sort (gnu coreutils) 8.20 under ubuntu 13.04.

the data:

original output             "sorted" output 0.12000000e-07 2.27723e-26  0.10000000e-07 1.84556e-26 0.17000000e-07 3.4771e-26   0.10000000e-08 2.99263e-27 0.13000000e-07 2.50426e-26  0.11000000e-07 2.05792e-26 0.90000000e-08 1.64135e-26  0.12000000e-07 2.27723e-26 0.18000000e-07 3.73627e-26  0.13000000e-07 2.50426e-26 0.80000000e-08 1.44369e-26  0.14000000e-07 2.73749e-26 0.70000000e-08 1.25438e-26  0.15000000e-07 2.97754e-26 0.60000000e-08 1.07324e-26  0.16000000e-07 3.22419e-26 0.50000000e-08 9.01209e-27  0.17000000e-07 3.4771e-26 0.14000000e-07 2.73749e-26  0.18000000e-07 3.73627e-26 0.40000000e-08 7.37598e-27  0.19000000e-07 4.00053e-26 0.30000000e-08 5.8135e-27   0.20000000e-07 9.26608e-26 0.20000000e-08 4.36327e-27  0.20000000e-08 4.36327e-27 0.20000000e-07 9.26608e-26  0.30000000e-08 5.8135e-27 0.10000000e-08 2.99263e-27  0.40000000e-08 7.37598e-27 0.10000000e-07 1.84556e-26  0.50000000e-08 9.01209e-27 0.19000000e-07 4.00053e-26  0.60000000e-08 1.07324e-26 0.15000000e-07 2.97754e-26  0.70000000e-08 1.25438e-26 0.11000000e-07 2.05792e-26  0.80000000e-08 1.44369e-26 0.16000000e-07 3.22419e-26  0.90000000e-08 1.64135e-26

and clarify: i've tried both

$ ./myscript.sh | sort -g

and 

$ ./myscript.sh > tempfile.txt $ sort -g tempfile.txt

with same results - , looking @ temp file can verify there's nothing fishy - doubt it's related command.

i did sort -g file, got this:

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...

c++ - qgraphicsview horizontal scrolling always has a vertical delta -

Image
i've subclassed qgraphicsview custom canvas used in cad application. i've reimplemented qgraphicsview::wheelevent check keyboard modifiers control key and, if control key pressed, zoom. i'm trying implement horizontal scroll when user holds shift , uses wheel. the problem i'm having horizontal scrolling always scrolls 0.279. not huge problem, hugely annoying , points else being wrong. so, here questions: is right way implement horizontal scrolling? if not, is? how eliminate delta of 0.279? thanks in advance. code , sample output below void myview::zoom(int delta) { double factor = pow(1.2, delta/abs(delta)); this->scale(factor, factor); } void myview::scrollhorizontal(int level) { qpointf center = maptoscene(viewport()->rect().center()); qdebug() << "center: " << center.x() << ", " << center.y(); centeron(qpointf(center.x() - level, center.y())); } void myview::wheelevent(qwheeleve...
