i'm working on git alias , have run syntax issues @ current (incomplete) state: [alias] gup2 = !git checkout $1 && before=$(git stash list) && git stash save gup-temporary-stash && git fetch && git rebase -p origin/$1 && if [ "$before" != "$(git stash list)" ]; git stash pop; fi the problem seems start when double quotes introduced. i've tried many combinations of single quotes , double quotes escape sequences, can't seem find right combination. what syntactically correct way form above alias? after a year of using git alias, decided not worth trouble. in mind, benefit of using alias can put git foo instead of git-foo.sh and in fact if script named example here, can call as git foo.sh or if name script git-foo can call as git foo completely eliminating benefit of git alias in opinion. git syntax scripting crap compared writing external script, i have done .

i've been having lot of trouble taming resizable() method. had element had built, called "imgbox" contained img tag , img wanted make resizable. whole thing prepended "canvas" div, ended line: .prependto('#canvas')).find('img').resizable(image_resizeops); this worked fine firefox, chrome, , ie safari height resizable() method assigned ui_wrapper around img height of container canvas, i.e, height of #canvascontainer. if tried prepending #canvascontainer height assigned ui_wrapper height of container of canvascontainer, #wrapper. somehow parameters prepend part of chain getting mixed latter part of chain! decided couldn't trust values resizable() assigned ui_wrapper or img after call manually set ui_wrapper , img width , height wanted. i'm wondering if resizable() has reputation misbehaving , if there guidelines out there. thanks

i have list l of elements, natural numbers. want print them in 1 line single space separator. don't want space after last element of list (or before first). in python 2, can done following code. implementation of print statement (mysteriously, must confess) avoids print space before newline. l = [1, 2, 3, 4, 5] x in l: print x, print however, in python 3 seems (supposedly) equivalent code using print function produces space after last number: l = [1, 2, 3, 4, 5] x in l: print(x, end=" ") print() of course there easy answers question. know can use string concatenation: l = [1, 2, 3, 4, 5] print(" ".join(str(x) x in l)) this quite solution, compared python 2 code find counter-intuitive , slower. also, know can choose whether print space or not myself, like: l = [1, 2, 3, 4, 5] i, x in enumerate(l): print(" " if i>0 else "", x, sep="", end="") print() but again worse had in pyth

for app i'm using leaflet , went pretty far it, i'm sure understood "leaflet way" of getting things done. as have 1 static layout of markers created simple mustache template, inserts variable data , gives me html: can.view("leads/popup", viewoptions) this works expected , results in html string, gets displayed. but when close , reopen popup results in empty popup content. var popup = l.popup({maxwidth: 1000, closeonclick: true}, marker); popup.setcontent(can.view("leads/popup", viewoptions)); var marker = l.marker(l.latlng(lng, lat), {icon: l.divicon({ classname: 'lead-icon lead_'+lead._id.$oid, iconsize: [size, size], html: '<span class="marker-label">' + label + '</span>' }) }); marker.bindpopup(popup); self.displaymarker(marker); what thought extending l.popup class , set _content fixed html code. i'm unsure if isn't little bit overpowered. thanks lot help,

i processing stored dates , times. store them in file in gmt in string format (i.e. ddmmyyyyhhmmss ). when client queries, convert string struct tm , convert seconds using mktime . check invalid datetime. again convert seconds string format. these processing fine, no issues @ all. but have 1 weird issue: stored date , time in gmt locale gmt. because of day light saving, locale time changed gmt+1. now, if query stored date , time 1 hour less because mktime function uses locale, i.e. gmt+1, convert struct tm seconds ( tm_isdst set -1 mktime detects daylight savings etc. automatically). any ideas how solve issue? use _mkgmtime / timegm complement mktime . time_t mkgmtime(struct tm* tm) { #if defined(_win32) return _mkgmtime(tm); #elif defined(linux) return timegm(tm); #endif }
