simple question: alarmmanager always cleared after reboot? cleared after reboot on devices , when user boots device shortly after booted off? i need know because recreate app's alarm in onbootreceiver , want avoid having double alarms set. is alarmmanager cleared after reboot? definitely on full reboot. there devices have "quickboot" (htc comes mind), , have not run experiments see behavior there. and when user boots device shortly after booted off? yes. i need know because recreate app's alarm in onbootreceiver , want avoid having double alarms set. alarms in hashmap keyed pendingintent . setting alarm using equivalent pendingintent should replace prior alarm. "equivalent", mean: same operation (activity, service, broadcast) same request code equivalent intent (matches via filterequals() , pretty means matches on except extras) and i'd nervous using flag_cancel_current when defining new pendingintent

in view i'm overriding "touches*" methods let user draw on screen. i'm recording locations. in addition have 2 gesture recognizers on view detect single tap , double tap. if move finger little bit , short enough, recording small "draw" gesture. when raising finger, additional tap gesture triggered. trial , error possibly figure out minimum time , movement threshold i'm sure there smarter ways? need know after how movement and/or save assume no tap gesture trigger. you can avoid tap gestures. instead of can recognize taps in touch events itself. - (void)touchesended:(nsset*)touches withevent:(uievent*)event { if(touches.count == 1) { if([[touches anyobject] tapcount] == 1) { // action here single tap } else if([[touches anyobject] tapcount] == 2) { // action here double tap } } } and have set global bool variable check whether user moved finger on screen. bool

i'm using python 2.7 , scikit-learn fit dataset using multiplicate linear regression, different terms multiplied instead of added in sklearn.linear_models.ridge . so instead of y = c1 * x1 + c2 * x2 + c3 * x3 + ... we need y = c1 * x1 * c2 * x2 * c3 * x3... can enable python , sklearn fit , predict such multiplicative/hedonic regression model? i think should able regular linear regression manipulating input data set (data matrix). the regression y ~ c1 * x1 * c2 * x2 *... equivalent y ~ k * (x1 * x2 *...) k constant so if multiply of values in design matrix together, regress on that, think should able this. i.e. if data matrix, x, 4 x 1000 features x1, x2, x3, , x4, use pre-processing step create new matrix x_new, 1 x 1000 single column equals x1 * x2 * x3 * x4, fit y ~ x_new (clf = linearregression(), clf.fit(x_new,y))

my grid view working okay , displays image sdcard.when long press image contextual task box open.one of option view(to view in full screen).i dont know how id or postion of selected image can pass activity open in fullscreen. public class mainactivity extends activity { public class imageadapter extends baseadapter { private context mcontext; arraylist<string> itemlist = new arraylist<string>(); public imageadapter(context c) { mcontext = c; } void add(string path){ itemlist.add(path); } @override public int getcount() { return itemlist.size(); } @override public object getitem(int position) { // todo auto-generated method stub return itemlist.get(position); } @override public long getitemid(int position) { // todo auto-generated method stub return 0; } @override public view getview(int position, view convertview, viewgroup parent) {

how convert output of rgb2ycbcr rgb in octave? can't find ycbcr2rgb function in image package. i finished rewriting rgb2ycbcr , implementing ycbcr2rgb octave's image package. part of next image package release (likely happen @ end of summer). clone image package repository or download individual functions manually: the ycbcr2rgb function ; the new rgb2ycbcr function ; the private function calculations.

in c++ program, have std::list , std::map (although using boost:unordered_map) , know elegant way of inserting elements in list map. key result of method call on elements on in list. so example have: std::list<message> messages = *another list elements*; std::map<std::string, message> message_map; and want insert elements list map key being message.id(), every message in messages. is there way without looping on list , doing manually? i can't use c++11 still interested in c++11 solutions interests sake. able use boost. thank you. a c++11 solution: can use std::transform transform std::list elements std::map elements: std::transform(message.begin(), messages.end(), std::inserter(message_map, message_map.end()), [](const message& m) { return std::make_pair(m.id(), m); }); the equivalent can done c++03 passing function pointer instead of lambda.

the question is: consider following location: [-72, 42] , range (circle) of radius 2 around point. write query find states intersect range (circle). then, should return total population , number of cities each of these states. rank states based on number of cities. i have written far: db.zips.find({loc: {$near: [-72, 42], $maxdistance: 2}}) and sample output of is: { "city" : "woodstock", "loc" : [ -72.004027, 41.960218 ], "pop" : 5698, "state" : "ct", "_id" : "06281" } in sql group "state", how able here while counting cities , total population? assuming follow mongoimport routine zipcode data (i brought mine collection called zips7): mongoimport --db mydb --collection zips7 --type json --file c:\users\drew\downloads\zips.json or mongoimport --db mydb --collection zips7 --type json --file /data/playdata/zips.json (depending on os , paths) then db.zips7.ensurei

this input <input type="text" name="price" class="solo-numeros"> with function $(".solo-numeros").blur(function() { var numb = parsefloat($(this).val().replace(/\d/g,"")).tofixed(2); $(this).val(numb); }); i try change result input float 2 decimals so try 555.61 but on blur value change to 55561.00 why that???? this happens because you're removing non-numeric characters ( \d ), such period. "55.61" becomes "5561" , made two-decimal string-representation of float, hence "5561.00" references: javascript regular expressions . string.replace() . number.tofixed() .

there couple of charting libs out there, of them not responsive. i have tried morris.js isn't responsive. so looking 1 responsive , free , looks morris.js( no highcharts, flot, google ) anybody? try amcharts: http://www.amcharts.com/javascript-charts/ they respond container changes dynamically perfect adaptive layouts.

i'm having problem iis , acl's. i have configured mvc application under dedicated apppool. apppool runs under applicationpoolidentity (which in case user iis apppool\accountinfo.local = same name website). i gave full control user on root folder , made sure permissions inherited. when access home page runs fine , can access it. however, when try access static content, in subfolder (content/site.css) error 401.3. i have made sure permissions inherited , if go effective permissions can see user have full control. i have enabled failed request tracing , security auditing don't log files, nor events in event viewer. what missing here? ok, got it. apparently requests static content don't go through applicationidentity through standard iusr account. once gave user read permissions on folder, started working. learnt new today.

okay, have code below , keep getting run-time errors , i'm thinking flaw in codes logic. i'm trying use setoneotherpicture method pick picture , set array later called on displayed in showartcollection method. i've been given 2 parameters, which , pref . can me this? thanks. public class house { string owner; picture pref; picture favpic; picture [] picarray = new picture [3]; public void showartcollection () { artwall awall = new artwall(600,600); awall.copypictureintowhere(favpic,250,100); awall.copypictureintowhere(pref,51,330); awall.copypictureintowhere(pref,151,330); awall.copypictureintowhere(pref,351,280); awall.show(); } public void setoneotherpicture (int which, picture pref) { this.picarray [which] = new picture (filechooser.pickafile ()); } public static void main (string [] args) { house phdshouse = new house ("mad ph.d."); picture favpic = new picture (); picture pref = new picture ();
