really silly problem here. in visual studio 2010, text cursor has changed blinking line, blinking grey box around characters. when type overwrites text in front of it. i'm not sure how off? it's happens when press insert key in microsoft word , overwrite mode gets turned on. i'm working on mac windows virtual machine when hit insert it's shortcut key parallels (the virtual machine program i'm running). would appreciate help!! if pressing insert key doesn't work, try doubleclicking ins/ovr label in lower right corner of visual studio.

if have model nullable field: class something(models.model): parameter = models.floatfield(blank=true,null=true) i want handle in view or template. if something.parameter has value, want return value, , if null, want return 'n/a'. if use: something = something.objects.get(id=1) output_string = 'parameter value: %s' % (something.parameter or 'n/a') then works, except in case something.parameter=0, returns 'n/a' rather desired '0'. how can correct behaviour? is there way of doing directly in template? use default_if_none template filter: {{ value|default_if_none:"n/a" }}

i'm aware of os.listdir , far can gather, gets filenames in directory memory, , returns list. want, way yield filename, work on it, , yield next one, without reading them memory. is there way this? worry case filenames change, new files added, , files deleted using such method. iterators prevent modifying collection during iteration, taking snapshot of state of collection @ beginning, , comparing state on each move operation. if there iterator capable of yielding filenames path, raise error if there filesystem changes (add, remove, rename files within iterated directory) modify collection? there potentially few cases cause iterator fail, , depends on how iterator maintains state. using s.lotts example: filea.txt fileb.txt filec.txt iterator yields filea.txt . during processing , filea.txt renamed filey.txt , fileb.txt renamed filez.txt . when iterator attempts next file, if use filename filea.txt find it's current position in order find next file , filea.txt n...
