i have range of integer intervals, e.g. [1, 5], [1,3], [3,4] create density plot. suppose want plot of number of intervals overlapping each integer in entire range. using data above might looks this: 3 x 2 x x x x 1 x x x x x 1 2 3 4 5 the obvious (and terrible) way can think of doing loop through every interval , add integers single vector, use hist() or similar function create plot. there straightforward way this? thanks! you seem proposing this: x <- list(c(1,5),c(1,3),c(3,4)) hist(unlist(lapply(x,function(z) seq(z[1],z[2])))) # hist plot(density(unlist(lapply(x,function(z) seq(z[1],z[2]))))) # density and yes, - describe - obvious solution.

i have sql server db ( tables etc) , ive installed ef6 in order use async stuff ( p.s. im new ef). so added : played wizard , created valid edmx files. my db name dump added dumpentities suffix :' so can : de = new dumpentities1(); var data=de.agegroups.tolist() but why don't have dbcontext ? see in many places ? is xxxentityes replacement dbcontext ? cause seems can actions xxentites ... edit ive searched "dbcontext" in solution , apprently have : so going on here? does using xxxentiyies new way ?( , not doing xxxcontext = new xxxcontext() ...even if wanted - dont have it...) you should not use dbcontext directly (that not make sense) in entity framework. instead use own custom context - class inherited dbcontext holds sets specific application. when use database first approach custom entity class generated based on edmx file data, in turn generated based on database schema. regarding naming... not obvious cust

in current work i'm trying encode images h264 video using ffmpeg's c library. resulting video plays fine in vlc, has no preview image. video can play in vlc , mplayer on ubuntu, won't play on mac or pc (in fact, causes "vtdecoderxpcservice quit unexpectedly" error on mac). if run resulting file through ffmpeg using command line, resulting file has preview image, , plays correctly everywhere. apparently file out of program corrupt in weird place, don't have output during compilation or run indicate where. can't share code @ moment (work code isn't open source yet :-( ), have tried number of things: writing header , trailer data (av_write_trailer) , no frames writing frames minus trailer (using avcodec_encode_video2 , av_write_frame) adjusting our time_base , frame pts values encode 1 frame per second removing variable frame rate code numerous other variants won't bother here in creating project, i've followed following tutorial

i have database contains articles pre-calculated quality scores ranging 0 10 (with 10 being best quality) , each article has published date. here example database schema. create table `posts` ( `id` int(10) unsigned not null auto_increment, `title` varchar(255) not null, `content` longtext not null, `score` int(10) unsigned not null default '0', `published` datetime not null, primary key (`id`) ) engine=innodb auto_increment=357 default charset=latin1; how can order articles newest , best scored? for example, following doesn't work because places scored 10 articles first if old. newest scored 9 article appears after 10 s. select * posts order score desc, published desc; if order published first, score value has no effect because published times unique. select * posts order published desc, score desc; i need somehow order these records higher scored articles come first, place them lower in list older get. here quick sample data made. i

i trying parse , display images feed has imgage url inside tags. example this: *note>> http://someimage.jpg not real image link, example. have done far. public void startelement(string uri, string localname, string qname, attributes atts) { chars = new stringbuilder(); if (qname.equalsignorecase("content:encoded")) { if (!atts.getvalue("src").tostring().equalsignorecase("null")) { feedstr.setimglink(atts.getvalue("src").tostring()); log.d(tag, "inside if " + feedstr.getimglink()); } else { feedstr.setimglink(""); log.d(tag, feedstr.getimglink()); } } } i believe part of programming needs tweaked. first, when qname equal "content:encoded" parsing stops. application runs endlessly , displays nothing. second, if change initial if qname cannot equal "purplebunny" works perfect, except there no
