i have numeric variable, k=3.5e-5 (its values calculated throughout script). want write value somewhere (title, text in plot, etc) in plot as: k_{root} = 3.5 10^{-5} cm /d i have tried functions bquote , substitute , no 1 worked. let's put question in examples. have tried following: 1) png("exp_1.png") kroot = 3.5e-5 plot(1:10,1:10, text(4,9,bquote(italic(k[root])~"="~.(kroot)~"cm/d"))) dev.off() try favorite function, paste(). plot(1:10,1:10, text(4,9,gsub("e",paste("k[root]=",format(k,scientific=true),"cm/d",sep=" "),replacement=" 10^"))) you can replace "e" here using function gsub. i've edited answer include this. the output: > k=.0000035 > k [1] 3.5e-06 > gsub("e",paste("k[root]=",format(k,scientific=true),"} cm/d",sep=" "),replacement=" 10^{ ") [1] "k[root]= 3.5 10^{ -06 } cm/d"

i'm in process of developing wp8 app makes use of background location tracking abilities provided os. idea monitor users position , notify them when near types of places. so far seems work fine , when running location tracking works expect. the problem is, seems phone times out background apps after around 4 hours, stopping location tracking. i can understand why microsoft did it, preserve battery life etc. there's not point having background location tracking app has manually restarted every 4 hours! if user chooses run app , made aware of potential battery hit, surely should able run indefinitely - point of course, if system runs out of resources or similar that's fair enough. does have experience this? there must hundreds of others apps in store have run issue have thought? , presumably there must way of keeping location tracking running? i've tried periodically updating live tile (using dispatchertimer) while tracking running doesn't seem enough ke

i seem have strange issue caused either visual studio or mercurial. localised single project, i'm guessing in project configuration causing issue. at difficult specify point, when perform action in visual studio, update every line ending in given file, means when @ file in sourcetree, every line has changed. i can replicate using nuget add package dependency; packages.config entirely replaced. if commit changes, including line endings, later same issue occur. workaround have shelve changes , reapply them, whereupon lines written correctly. i'm not sure application blame here. did make mistake of allowing sourcetree change mercurial configuration, issue have fixed, i'm not sure if has persisted. i thought might issue mercurial.ini files or hgrcs don't seem contain untoward. here's mercurial.ini [ui] username = ....

using mathematica, can compute mathematical representation of function want code in c++. say like: f=log[2*x+3*y]+sin[4*x+6*y] it makes sense in case computation: temp=2*x+3*y f=log[temp]+sin[2*temp] is there way expression reduce execution time / number of operations / size of expression or metric given more complex mathematical expression? although doesn't work simple example, can try following in mathematica experimental`optimizeexpression[{log[(2*x^3 + 3*y)^2] + sin[2 (2*x^3 + 6*y)^2]}] as result get experimental`optimizedexpression[ block[{compile`$3, compile`$4}, compile`$3 = x^3; compile`$4 = 2 compile`$3; {log[(compile`$4 + 3 y)^2] + sin[2 (compile`$4 + 6 y)^2]}]]

this basic question i'm little bit confounded. understanding convention dictates class definitions capitalised object instances not. when following: app = require("app"); module.exports = app.authmanager = ember.object.extend({ apikey: null, // load current user if cookies exist , valid init: function() { this._super(); var accesstoken = $.cookie('access_token'); var authuserid = $.cookie('auth_user'); if (!ember.isempty(accesstoken) && !ember.isempty(authuserid)) { this.authenticate(accesstoken, authuserid); } }, // ... } i assume defining authmanager's class definition. if this: module.exports = app.applicationroute = ember.route.extend({ init: function() { this._super(); app.authmanager = app.authmanager.create(); } }); my understanding app.authmanager = app.authmanager.create(); instantiates instance , applicationrouter pretty first thing executed in ember app.

what's fastest, safest, , practical way of handling conditions inside function condition match must passed before function can proceed code @ all? below have function returns on condition failure, , function checks condition success: function x() { if ( !condition ) return; [code] } or function y() { if ( condition ) { [code] } } mccabe's cyclomatic complexity punishes functions more 1 return statement. guess provide formalism supports structured programming (one entry point each function/ "goto statement considered harmful" ) taken extreme, i.e. 1 exit point each function. reducing number of return statements in function reduces number of break-points insert in debugging situation final values of function local variables inspected. if development method involves frequent use of debugger argue using y() approach.

there 2 approaches i've been thinking storing data in cookies. 1 way use 1 cookie data , store json string. the other approach use different cookies each piece of data. the negatives see first approach it'll take more space in headers because of json characters in cookie. i'll have parse , stringify json take little processing time. positive 1 cookie being used. there other positives missing? the negatives see second approach there more cookie key value pairs used. there 15-20 cookies storing. expires date same each cookie. from understand max number of cookies per domain around 4000. not close number yet. are there issue overlooking? approach best? edit - these cookies managed javascript. if hand out data storage users (which cookies do), should encrypt data, or @ very least sign it. this needed protect data tampering. at point, size considerations way off (due padding), , performance overhead of parsing json (encryption cause greater overhea

i'd incoming java servlet web requests invoke rabbitmq using rpc approach described here . however, i'm not sure how reuse callback queues between requests, per rabbitmq tutorial linked above creating new callback queue per every request inefficient (rabbitmq may not cope if using queue ttl feature ). there 1-2 rpc calls per every servlet request, lot of servlet requests per second. i don't think can share callback queues between threads, i'd want @ least 1 per each web worker thread. my first idea store callback queue in threadlocal, can lead memory leaks. my second idea store them in session, not sure serialize , sessions not replicated/shared between web servers, imho not solution. my infrastructure tomcat / guice / stripes framework. any ideas robust/simple solution is? am missing in whole approach, , over-complicating things? note 1- question relates overall business case described here - see option 1. note 2 - there seemingly related quest
