assume using priorityqueue class java.util. want remove largest number priorityqueue pq, assume @ head of queue. will following work? // 1 int head = pq.peek(); pq.dequeue(head); // 2 int head = pq.dequeue(pq.peek()); would work same non-primitives well? queue#peek , queue#element return head value of queue, queue#poll , queue#remove return and remove it. it looks like int head = pq.poll(); is want. and: only work non-primitive values because queue store objects only. trick is, (i guess) queue stores integer values , java 1.5+ can automatically convert results int primitives (outboxing). feels queue stored int values.

i have user registration form. has field date of birth. not compulsory in database not on ui. while create when goiing assign objects property, have convert in date format. if have not selected it, become null in formcollection object. like user.dob=convert.todatetime(collection["dob"]); now issue if collection["dob"]is null throws exception. can not assign default value here. how can handle situation? you'll better off using datetime.tryparse this. this way can check whether you're working valid date or not. datetime dateofbirth; bool isvaliddateofbirth = datetime.tryparse(collection["dob"], out dateofbirth); if(isvaliddateofbirth) { // stuff } else { // other stuff }

i have created default android system images (like userdata.img , system.img , ramdisk.img ) following instructions @ android page . what create customized android system images aosp(by removing apps & code-dependencies, unnecessary target board, e-mail, browser) & run on target board reduce foot-print of resulting system images & speed-up boot-up time of target board. any pointers above mentioned customizations welcome. edit makefile: build/target/product/generic.mk , remove packages list. won't bother going how compile, etc. please note doing not remove code dependencies of packages (you'll have modify api in dalvik/ or frameworks/ hairy), eliminate packages incorporated in system image.

i using r make plots report. see plots don't seem smooth. new r don't know much. how smooth plots? also default plots filled solid colors want have hatched fills in pie charts , bar plots. there way in r, couldn't find through basic google search put question here. did try help(pie)? density: density of shading lines, in lines per inch. default value of ‘null’ means no shading lines drawn. non-positive values of ‘density’ inhibit drawing of shading lines. pie(c(1,2,3),density=c(1,2,20)) hist(runif(200),density=c(10,20,30))

papers have been written describing how hough transform can generalised detect shapes circles , parabolas. i'm new computer vision though , find these papers pretty tough going. there code out there detection more want. wondering if briefly describe in bullet points or pseudo-code how hough transforms used detect parabolas in images. amazing. or if knows basic explanations online haven't come across enough :). thanks :). interesting question. looks great resource . included summary (loosely quoted). see source mathworks @ bottom of answer - matlab has houghlines , houghpeaks functions useful you. hope helps. run edge detection algorithm, such canny edge detector, on subject image input edge/boundary points hough transform (line detecting) generate curve in polar space (radius, angle) each point in cartesian space (also called accumulator array) extract local maxima accumulator array, example using relative threshold in other

i've done bit of searching around web why use rdf instead of xml semantic modeling. came across article , it's still not clear me. wondering if give me couple of points on why cannot use xml instead of rdf. limited understanding, xml's extensibility gives way define document not give mechanisms describe meaning of it. examples appreciated. thank much from limited understanding, xml's extensibility gives way define document not give mechanisms describe meaning of it. you're correct. xml describes data not @ describing relationship between different data elements. rdf describes data , data relationships. think of rdf textual meta-database. article calls rdf semantic model. here's rdf example : <?xml version="1.0"?> <rdf:rdf xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#" xmlns:cd="http://www.recshop.fake/cd#"> <rdf:description rdf:about="http://www.recshop.fake/cd

i've been reading jon skeet's c# in depth: second edition , noticed different in 1 of examples myself. he has similar following: var item = someobject.where(user => user.id == id).single(); whereas i've been doing following: var item = someobject.single(user => user.id == id); is there real difference between two? know jon skeet pretty c# god tend think knowledge in area better mine might misunderstanding here. hope can help. the queries should equal when tree evaluated, depending on target actual execution differ (ie l2s optimization).

in previous post ( my program never releases memory back. why? ) show fastmm can cache (read hold itself) pretty large amounts of memory. if application loaded large data set in ram, after releasing data, see impressive amounts of ram not released memory pool. i looked around , seems calling setprocessworkingsetsize api function "flush" cache disk. however, cannot decide when call function. wanted call @ end of onclick event on button performing ram intensive operation. however, people saying may cause av. if used function successfully, please let me (us) know. many thanks. edit: 1. after releasing data set, program still takes large amounts of ram. after calling setprocessworkingsetsize size returns few mb. argue nothing released back. agree. memory foot print small , not increasing after using program (for example when performing normal operation not involves loading large data sets). unfortunately, there no way demonstrate memory swapped disk ever loaded
