i working on huge project using entity framework. because made entities time-dependent not possible use relations between entities anymore (i manage relations myself). problem came not longer able query data before. have entity called student . entity contains collection of books (list) belong student. each book contains author property comes database well. load students theirs book , corresponding authors either have write hundreds of custom queries (f.e. linq) or lazy load them results in big performance impact. great if use inlude of entity framework without relations. know how achieve this? thank you. if entity framework not managing relations between tables, has no way of using .include() create joins in sql call. best option add related entities parent normal, use [notmapped] attribute. can use custom sql call perform lookups , populate properties when need them. confused, however, statement because entities "time-dependent" can't use relationshi

i have data stored in byte array. how can convert data hex string? example of byte array: array_alpha = [ 133, 53, 234, 241 ] using str.format : >>> array_alpha = [ 133, 53, 234, 241 ] >>> print ''.join('{:02x}'.format(x) x in array_alpha) 8535eaf1 or using format >>> print ''.join(format(x, '02x') x in array_alpha) 8535eaf1 note: in format statements, 02 means pad 2 leading 0 s if necessary. important since [0x1, 0x1, 0x1] i.e. (0x010101) formatted "111" instead of "010101" or using bytearray binascii.hexlify : >>> import binascii >>> binascii.hexlify(bytearray(array_alpha)) '8535eaf1'

why did apple choose use delegation communication amongst sdk objects , post notifications notification center others? in particular, i'm thinking set of keyboard appearance notifications come uiwindow. is because notification center system means more 1 object can use keyboard appearance action trigger change state, whereas 1 object have been able act delegate implementation? delegation allows execute methods (and pass parameters) 1 class another. allows method fired when class not imported. delegation allows multiple view controllers (or otherwise classes) fire methods in single view controller. notification center, on other hand, listens , waits until hears message waiting for. allows multiple listeners in multiple view controllers wait , listen given message. you delegation 1/many 1 relationship while notification center 1/many 1/many relationship.

simple question: need image appear in middle of paragraph of text, however, image larger height of each line of font, pushes open horizontal "gap" in text make room itself. fix this, could: 1) shrink image, not larger font. 2) use position:absolute but don't want shrink further, small enough "technically fit" between each line of text, except need use few pixels of white area above , below line of text in. and can't use position:absolute, because image's position in top left corner of window, instead of in paragraph want it. i thought perhaps put dummy "placeholder" image of size 1 pixels paragraph. then, use position:absolute on real image, , continually set real image @ same location dummy image is. haven't researched see if possible, seems bit excessive such simple thing. there easier way? edit: found adding: margin:-20px; image's style works!!! margin:-20px; jsfiddle example: http://jsfiddle.net/j7tlx/3/ i

in 1 interview asked that suppose have 25 mb of memory , have 3 processes of 10 mb each. how assure process should not run out of memory ? i replied if use placement new survive. asked me how relate placement new realloc ? i want know placement new related realloc ? realloc isn't valid placement new. since memory might end in new location, pointers referring object become invalidated, pointers contained within objects themselves. think of linked list example. the interviewer looking mention of virtual memory.

i familiar using java.util.scanner next() , hasnext() , nextint() , nextline() , , parse input. is there else should use in scala? this data isn't structured according grammar; it's more ad-hoc that. for example, lets had inventory. each line of input starts name, has quantity of items, has ids items firetruck 2 a450m a451m machine 1 qzlt keyboard 0 i see console has methods such readint() , reads entire line of input; equivalent of nextint() doesn't seem exist. java.util.scanner trick. there else should use (for example, returns scala rather java types)? no there no equivalent scala implementation. don't see reason 1 java.util.scanner work fine , java primitives types converted scala types implicitly. so "for example, returns scala rather java types", scanner return scala types when used in scala.

from bs4 import beautifulsoup xmlcontent = "some text <tags>" bs = beautifulsoup(xmlcontent, "xml") print bs outputs: <?xml version="1.0" encoding="utf-8"?> text <tags> is possible not output: <?xml version="1.0" encoding="utf-8"?> i know if using lxml , remove added <body> tags do: bs = beautifulsoup(xmlcontent, "lxml") print bs.body.next is there equivalent use xml xml version , encoding not included? i choosing use xml on lxml contents being parsed in xml format - best choice or can use lxml xml content? this seems work: from bs4 import beautifulsoup xmlcontent = "some text <tags>" bs = beautifulsoup(xmlcontent, "xml") bs = bs.encode_contents() print type(bs) # it's string print bs # text <tags>

i trying optimize search node in treenodecollection . original method uses recursive approach: public ugtreenode findnode(baseid nodeid, treenodecollection nodes) { foreach (ugtreenode n in nodes) { if (n.node_info.description.base_id.id == nodeid.id && n.node_info.description.base_id.rootid == nodeid.rootid && n.node_info.description.base_id.subid == nodeid.subid) return n; ugtreenode n1 = findnode(nodeid, n.nodes); if (n1 != null) return n1; } return null; } i tried storing nodes in dictionary , use dictionary.trygetvalue search node: public ugtreenode findnode(baseid nodeid, treenodecollection nodes) { ugtreenode res; _nodescache.trygetvalue(nodeid.id, out res); return res; } but turns out second approach way slower first (appoximately 10 times slower). possible reasons this? the recursion may faster when search 1 of first items in tree. depends

here problem, put piece of code in jsfiddle, , works perfectly. put same code on website, adding in header include jquery , jquery ui (links directly jquery sites, not hosting files locally) , code doesn't work. i attempting "sortable" effect work in project. not code either. been every single piece of code has draggable, movable, etc. uses jquery. i'm missing , can't think of is. i own servers in datacenter, , running cpanel, have full access server if need make changes. when test code on jsfiddle, when click , drag tags, doesn't highlight text , moves <li> tags allowing me reorder list. on website, starts highlighting text , doesn't move file. html same on both places. any ideas? jsfiddle : http://jsfiddle.net/ygrup/ code: (some of code still there interacts php code; however, removed php code example testing) <!doctype html public "-//w3c//dtd xhtml 1.0 transitional//en" "http://www.w3.org/tr/xhtml1/dtd/

i using nicedit editor in app , users of our website use paste data ms word or other sources, hence ui breaks up, have decided remove formatting html using jquery. what did removed inline style , class, creating problem removing bold , italics too, want retain it. is simple way of removing style except bold using jquery. example : <div style="color:red; font-size:13px; font-weight:bold;">test div </div> in above element want as <div style="font-weight:bold;">test div </div> i think way store styles want, remove them , set them again. $('.selector').each(function() { var keepstyle, $el; $el = $(this); keepstyle = { font-weight: $el.css('font-weight'), font-style : $el.css('font-style') }; $el.removeattr('style') .css(keepstyle); })
