wow, 1 though! i'm trying find in php % of value relative y axis. if refer graph : http://en.wikipedia.org/wiki/semi-log_graph (2009 outbreak of influenza a), let's want find % value "256" on chart. visually, it's easy : it's bit more 1/3 or 33%. if @ 1024 value, it's around 50% of height of y axis. 131072 100%. so how calculate php? let's take graph , take x = day 0 , y = 256. 256 % of y ? thanks lot can compute baby :) percent = 100 * ( log(y) - log(y1) ) / ( log(y2) - log(y1) ) where y = value y1 = smallest value in y-axis y2 = largest value in y-axis. when y1 = 1.0 can simplify other answers given here (since log(1)=0 definition) percent = 100 * log(y)/log(y2) note not log charts have 1.0 lowest value.

suppose have model entry, field "author" pointing model author. suppose field can null. if run following queryset: entry.objects.filter(author=x) where x value. suppose in mysql have setup compound index on entry other column , author_id, ideally i'd sql use "author_id" on entry model, can use compound index. it turns out entry.objects.filter(author=5) work, no join done. but, if author=none, django join author, add clause author.id null. in case, can't use compound index. is there way tell django check pk, , not follow link? the way know add additional .extra(where=['author_id null']) queryset, hoping magic in .filter() work. thanks. (sorry not clearer earlier this, , answers lazerscience , josh). does not work expected? entry.objects.filter(author=x.id) you can either use model or model id in foreign key filter. can't check right yet if executes separate query, though i'd hope wouldn't.

i working asp.net , have 2 gridvew controls , link buttons. now, bind these gridviews, have call web services , data access. since pulling large amount of data, page loads slow. wondering if there way partial page load, meaning show link buttons first show rest of gridview data available (to bind gridivews). is there way can accomplish this?

i have string: "some text\nandsomemore" i need remove "\n" it. i've tried "some text\nandsomemore".gsub('\n','') but doesn't work. how do it? reading. you need use "\n" not '\n' in gsub. different quote marks behave differently. double quotes " allow character expansion , expression interpolation ie. let use escaped control chars \n represent true value, in case, newline , , allow use of #{expression} can weave variables and, well, pretty ruby expression text. while on other hand, single quotes ' treat string literally, there's no expansion, replacement, interpolation or have you. in particular case, it's better use either .delete or .tr string method delete newlines . see here more info

in oracle's sql*plus, results of select displayed in tabular manner. there way display row in key-value manner (like mysql's \g option )? the database working on (the schema not defined me) has bunch of columns named e.g. yn_enabled (yn = yes no) char(1) . when query result like id_mytable y y y ------------ - - - 3445 y n y so it's not clear columns have values (without having schema open in window). not built in sql plus, tom kyte has provided procedure called print_table this. run this: sql> exec print_table ('select * mytable id_mytable=123'); , see results like: id_mytable : 123 yn_enabled : y yn_something : n ...

i want current bitmap associated canvas can perform operations on it. can't see how though. i've seen examples create bitmap , set canvas use bitmap, can access later, i'm using canvas returned surfaceholder there's no constructor. for instance, examples show kind of thing: bitmap bmp = bitmap.createbitmap(xxx, yyy, bitmap.config.argb_8888); canvas c = new canvas(bmp); so @ point can see bmp. in case, canvas obtained by: final surfaceholder holder = getsurfaceholder(); canvas c = null; try { c = holder.lockcanvas(); so how can bitmap c? edit @reuben - may right, did wonder this. in short, aim capture current canvas contents have drawn "stuff", , make copy of it, reversed, put underneath. reflection. example of found performed via bitmaps, assumed needed somehow capture current canvas bitmap use it. if there better way can this, i'm ears! better late never :) bitmapdrawable bitdrawable = new bitmapdrawable(...

what easiest way create , save string .txt files? use tstringlist . uses classes, dialogs; // classes tstrings, dialogs showmessage var lines: tstrings; line: string; filename: string; begin filename := 'test.txt'; lines := tstringlist.create; try lines.add('first line'); lines.add('second line'); lines.savetofile(filename); lines.loadfromfile(filename); line in lines showmessage(line); lines.free; end; end; also savetofile , loadfromfile can take additional encoding in delphi 2009 , newer set text encoding (ansi, utf-8, utf-16, utf-16 big endian).

i'm new cocoa app dev, , i'm searching solution create windows tweetie main windows left tool bar , panel point selected icon. like screenshot : http://i.stack.imgur.com/qvxwu.jpg could me? it's lot of tweetie ui implemented using custom controls. you'll want subclassing nsview , how handle drawing , mouse events. there's nothing built cocoa framework this. the nsview documentation has info on view programming , drawing , , event handling . if you're new cocoa, may want start off built in, though, lot of work (and requires pretty understanding of how framework works).

if have template class specification so, template <typename t> class myclass { public: void fun1(); // ... void funn(); }; template <typename t> void myclass<t>::fun1() { // definition } // ... template <typename t> void myclass<t>::funn() { // definition } if change class template else, add parameter: template <typename t, typename u> class myclass { // ... }; then have change each function definition (fun1, ..., funn) agree class template specification: template <typename t, typename u> void myclass<t,u>::fun1() { //... } are there strategies avoiding this? use macros e.g. #define dflt_template template<typename t, typename u> #define dflt_class class<t,u> dflt_template void dflt_class::fun1() { // ... } or considered bad practice? to me, benefits of using macro here far overshadowed drawbacks. yes, if use macro if ever need add additional template parameter, you...

i have got confused shared_ptr. say, have classes: class foo { int _f; }; typedef std::shared_ptr<foo> fooptr; class bar { int _b; }; typedef std::shared_ptr<bar> barptr; class foobar : public foo, public bar { int _fb; }; int main () { foobar *fb1 = new foobar(); foobar *fb2 = new foobar(); fooptr f((foo *)fb1); barptr b((bar *)fb2); return 0; } because b.get() != fb2, should crash when program exit? or safe ? a shared_ptr<base> can safely take ownership of derived* , if base not have virtual destructor. however, works if shared_ptr knows derived type of object when takes ownership of it. if remove casts fooptr f(fb1); fooptr b(fb2); then you'd okay. casts, shared_ptr cannot know most-derived type of object when takes ownership of it, behavior undefined, if had said: foo* f = new foobar(); delete f; the best thing follow rule "a base class destructor should either public , virtual, or...

as not our development machines have internet access, want cache api docs of various libraries in our local network. thinking of webapp handles caching , listing available javadocs after uploads them (in jar format). ideally, source jars automatically pulled our maven repository (artifactory). i have not been successful in finding on google, i'm trying luck here. edit i have found site looking for: http://www.jarvana.com problem site not fulfill #1 requirement - offline availability. rephrase question to: there webapp works jarvana can deployed local server? it seems i'm looking doesn't exist, i've rolled own simple webapp serves javadocs local maven repository (transparently extracting jar files). it's far perfect, works requirements. if interested, shared on github: https://github.com/planbnet/javadoc-browser

i have user control outputcache: <%@ outputcache duration="86400" varybycontrol="lnkbtntopvanzari" %> where varybycontrol id of link button use switch active view of multiview contained in updatepanel . the problem when press link button, page full post back , view not switched. if remove outputcache directive, works great (pressing link button correct view shown via ajax). do know wrong? thanks. the varybycontrol parameter used vary depending on value of control specify. value of link button same, cache not varied. i believe intended used controls such dropdown lists, feasible output different based on selected value in list. you may want try using varybyparam , changing link button hyperlink, specifying view query parameter, or trying out varybycustom. otherwise possibly possibly split content of views separate user controls output cached, leaving multiview , link button outside caching.
