i'm looking chrome frame , i'm wondering how works.... http://scriptsrc.net shows it's javascript can embedded on page.... http://code.google.com/chrome/chromeframe/ shows install file... js prompt installation or something? the javascript detect , enable if it's there. (scriptsrc giving link file, on google cdn.) end user have one-time install of it, it's plug-in (like flash or java). quoting this page in google documentation: in internet explorer, check() determines if chrome frame installed. if not, user prompted install it.

this demo... , curious, can detect if window has been moved? if move firefox/chrome/ie around monitor? doubt it, wanted see since can check resize , focus/blurred windows. i can think of (heavy) work-around, check if window.screenx , window.screeny have changed every x milliseconds var oldx = window.screenx, oldy = window.screeny; var interval = setinterval(function(){ if(oldx != window.screenx || oldy != window.screeny){ console.log('moved!'); } else { console.log('not moved!'); } oldx = window.screenx; oldy = window.screeny; }, 500); though not recommend -- might slow , i'm not sure if screenx , screeny supported browsers

trying solve 2 equations 2 unknown using matlab , not liking input. where c 3.06 + 2.57j, , v 12: eq1 = 'c = a/10j' eq2 = '(6b)/50 + b/10j = a/10j + a/10' trying solve , b. suggestions of how put these in? matlab screwed up, syntax is sol = solve(eq1,x1,eq2,x2,..); it make more sense make solve({eq1,eq2,..},{x1,x2,..}) no, have write out arguments 1 one. anyway trick eq1, eq2, .. symbolic expressions must evaluated zero. instead of c = a/10j needs eq1=sym('c-a/10j') so try this: eq1 = sym('c - a/(10*i)'); % must evaluate 0 eq2 = sym('(6*b)/50 + b/(10*i) -( a/(10*i) + a/10)'); %must evaluate 0 sol = solve(eq1,'a',eq2,'b'); = subs(sol.a,'c',3.06+2.57j) b = subs(sol.b,'c',3.06+2.57j) produces a= -25.7000 +30.6000i , b=-20.6639 +29.6967i . note symbolic functions not understand 10j . needs 10*i . notatation 6b missing operator , needs 6*b . good luck! since problem linear

i've few .containers css selectors wraps around input boxes have same attributes except width , height. possible pass width , height when define class="container" ? maybe i'm not understanding correctly, want send width , height of container class elements class later on inherit width , height? not pure css. it's called cascading style sheets, because can't go in reverse, if makes sense. it's easy javascript, though. in jquery, example, do: $(document).ready(function() { var width = $('.container:first').css('width'); var height = $('.container:first').css('height'); $('.container').css({'width': width, 'height': height}); });

hi: in our application,we have retrive data database,for example,the table have columes:id,name,age,address,email. then of these propertis according client. if client need id, name, id name, if client need id, name, age, id, name, age. now want create class wrap these properties. not know field requested. string[] requestpro={"name","id"}; //this field specified client map<string, object> map=new hashmap<string, object>(); entity en=entity.newinstance(); for(string p:requestpro){ map.put(p, beanutils.getproperty(en, p)); } here can replace map class? if understand right, want dynamically add properties class, or rather: specific instance of class. the former possible e.g. in groovy, there metaclass object every class, can assign behavior @ runtime, latter possible in javascript, can assign behavior both object's prototype , object itself. neither of versions possible in java, using map or similar structure thing in java.

for project doing, want mac application accept plug-ins. whole idea of adding bundles application extend it's functionality. only came across small question, can't find answer to: i need include json parser in application, functionality. possible plug-in bundle use same parser? or every plug-in uses json parser, need include parser themselves? what best way separate bundles? on os x there 2 types of loadable things, dylib , plugin . (these 2 terms have specialized technical meaning in context of mach-o, binary format os x uses.) a loaded dylib can't refer libraries in executable, while loaded plugin can. side effect, dylib can loaded executable, plugin can loaded executable specify when make plugin. so want make plugin . there template in xcode that. don't forget specify target executable in linker flag, can set somewhere in inspector. for more, read code loading programming topics .

how can identify , remove 4 red points drawn in image those 4 points make polygon concave polygon that’s why want remove it. my goal convert concave polygon convex removing kind of point identifying , removing points. is there way identify , remove these kind of points? thanks use convex hull algorithm (such the graham scan ), , remove points not part of resulting convex hull. in example, convex hull consist of p1, p2, p3, p5, p7, p8, p9, p11, p12, p13, p14, p15, p16, p18, precisely points except red ones. note removing points inner angle greater 180 not result in convex polygon. take polygon example:

hi have issue on querying subsecond accuracy queries gql.. wondering if had similar issues or workarounds. the context problem i'm loading batches of many objects google data store @ once. thousands of objects added within single second. on retrieval, run pagination issue when i'd page based on datetime of when they're added. (the last added time ideal paging allows users data don't have.) since batches of entities added in within sub second quantum. paging problematic if need start paging batch of entities inserted in same second. seems app engine 1 box solution can't handle subsecond queries if try pass in datetime objects has fractions. i.e. have following query pass in datetime object fractions of second. locally i'm running python 2.6. test = gqlquery("select * table lastupdated > :1", minimumtime) if minimumtime 10:00:00.0500, result set still contain records lastupdated @ 10:00:00.0100, 10:00:00.0200 etc.. i'm th

i know if there's easier way other mod rewrite (using fusebox framework or directly in coldfusion) convert url follows: from: http://www.somedomain.com/salmahayek or http://localhost/someapp/salmahayek to: http://www.somedomain.com/index.cfm?action=profile.view&name=salmahayek or http://localhost/someapp/index.cfm?action=profile.view&name=salmahayek my app existing fusebox 5.5 application. i need add url above not static, i.e. "salmahayek" name. any appreciated thanks you potentially use "classic" way of doing (not sure if fusebox interfere), using 404 handler, should trick: set 404 hander on server, e.g. in .htaccess: errordocument 404 /404handler.cfm set 404handler.cfm wrap around framework, e.g.: <cfset variables.checksok = false> <!--- checks - example ---> <cfif cgi.redirect_url eq 'salmahayek'> <cfset variables.checksok = true> </cfif> <cfif v

i have build usercontrol in asp.net, , there property following. works fine when bound value integer. however, if bound field return null database, return invalid cast error. change nullable int not desirable because changes how programmer work control's property in code-behind. just wonder how these things should implemented? thanks, [defaultvalue(0)] public int fixedlo { { if (viewstate["fixedlo"] != null) return convert.toint32(viewstate["fixedlo"]); else return 0; } set { if (value == null) viewstate["fixedlo"] = 0; else viewstate["fixedlo"] = value; } } would checking dbnull trick?

adding @with(secure.class) controller blocks unauthenticated access. there way enabled actions, or except actions after it's enabled on controller? you can't secure module. niels said secure module more example solution. can build own security system @before annotation. here example: public class admin extends controller { @before(unless={"login", "authenticate", "logout", "othermethod"}) void checkaccess() { // check cookie } public void login() { render(); } public void authenticate(string email, string password) { // check params , set value in cookie } public void logout() { // delete cookie } i recommend read source code of secure module.

i'm curious community's opinions on server side frameworks (like django , ror) versus client side frameworks (like sproutcore , extjs). i know a bit of false dichotomy since there no reason why 1 cannot use both server , client side framework. in practical terms can huge headache. just example: cultivating expertise in 2 different languages, 2 different apis, , 2 different framework syntaxes achieve single goal terribly inefficient. the strategy feels right me pick 1 client or server side framework primary, , supplement necessary lightweight on other side. example, use ror on server primary supplemented on client jquery. or use extjs on client primary supplemented php on server. right i'm not sure side of fence fall on , interested in community's opinions , experiences. its false dichotomy. solve different subproblems of goal. apparently though, microsoft asp.net stuff pretty @ integrating client-side server side (i have never used myself howeve

in production, our delayed_job process dying reason. i'm not sure if it's crashing or being killed operating system or what. don't see errors in delayed_job.log file. what can troubleshoot this? thinking of installing monit monitor it, tell me precisely when dies. won't tell me why died. is there way make more chatty log file, can tell why might dying? any other suggestions? i've come across 2 causes of delayed_job failing silently. first actual segfaults when people using libxml in forked processes (this popped on mailing list time back). the second issue 1.1.0 version of daemons delayed_job relies on has problem ( https://github.com/collectiveidea/delayed_job/issues#issue/81 ), can worked around using 1.0.10 own gemfile has in it. logging there logging in delayed_job if worker dying without printing error it's because it's not throwing exception (e.g. segfault) or external killing process. monitoring i use bluepill monitor d

i want set intent filter handle urls like: http://mysite.com/?action=delete&id=30492 i've tried setting intent-filter follows: <intent-filter> <action android:name="android.intent.action.view" /> <category android:name="android.intent.category.default" /> <category android:name="android.intent.category.browsable" /> <data android:scheme="http" android:host="mysite.com" android:pathprefix="/?action="/> </intent-filter> however, doesn't work, , app not recognized being able handle url. know it's because i'm doing wrong pathprefix because when remove pathprefix works. know it's related having question mark in there because if remove question mark url , pathprefix , works. do need escape question mark in way? tried escaping slash ( android:pathprefix="/\?action=" ) doesn't work either. how can intent filter work? the query string
