i have div many childen. how move of them div using jquery ? code looks like: jquery("body").append("<div id='popupwrapper'></div>"); var myid = $('.floatingframelightblue1').attr('id'); jquery(myid).children().append("popupwrapper"); but doesn't work. i'm doing wrong? here have simple example of it: http://jsfiddle.net/lhr79/ as have told you. need use appendto instead of append , specify selector type (class, id... ) using . or # preceding name. in case: #popupwrapper popupwrapper id , not class.

c# - Can Expression.PropertyOrField be used to access a static property or field? -

the documentation of expression parameter of expression.propertyorfield states can null static members: an expression type contains property or field named propertyorfieldname . this can null static members . (emphasis mine) however, whenever pass null argumentnullexception . the documentation of method contradictory: the documentation of expression parameter states can null static members the documentation of argumentnullexception states thrown if expression null fact is : method can't used access static members, documentation of expression parameter incorrect. when expression correct type supplied, method doesn't work expected, because ever looks instance members. to access static field or property, use expression.makememberaccess instead.

quickfix - Why is a FIX connection dropping heartbeats when both endpoins are on the same server? -

we have 2 applications using quickfix engine, both running in same machine. see session ends due lack of heartbeats. how can since both running on same machine? fix heartbeat mechanism has nothing fact applications communicating using fix protocol run. if see session being dropped due lack of heartbeat have determine session did not send heartbeat (it fail respond «test request» message, if any) , why did happen. possible reasons are: server , client have different heartbeat interval settings , server not honor client's heartbeat interval (field #108 in «logon» message) , test request/response logic broken (or turned off). underlying transport errors (i.e. tcp/ip errors or udp packet drops). other software/hardware bugs. something else. hope helps. luck!

Python NumPy log2 vs MATLAB -

i'm python newbie coming using matlab extensively. converting code uses log2 in matlab , used numpy log2 function , got different result expecting such small number. surprised since precision of numbers should same (i.e. matlab double vs numpy float64). matlab code a = log2(64); --> a=6 base python code import math = math.log2(64) --> = 6.0 numpy code import numpy np = np.log2(64) --> = 5.9999999999999991 modified numpy code import numpy np = np.log(64) / np.log(2) --> = 6.0 so native numpy log2 function gives result causes code fail test since checking number power of 2. expected result 6, both native python log2 function , modified numpy code give using properties of logarithm. doing wrong numpy log2 function? changed code use native python log2 now, wanted know answer. no. there nothing wrong code, because floating points cannot represented on our computers. use epsilon value allow range of error while checking float ...

ruby - Why is rindex vs. index changing the output of selection sort? -

i working through basic algorithm exercises, , confused implementation of selection sort: def selection_sort(xs) len = xs.length len.times |i| low = xs[i...len].min tmp = xs[i] xs[i] = low xs[xs.rindex(low)] = tmp end xs end the code works fine, however, if use xs[xs.index(low)] = tmp instead of xs[xs.rindex(low)] = tmp , function not work on following tests: selection_sort([3, 6, 2, 7, 4, 1, 4, 5, 6, 7, 8, 0]) selection_sort([0, 8, 7, 6, 5, 4, 1, 4, 7, 2, 6, 3]) in mind, should not matter since index index whether coming right or left. wouldn't using rindex vs index change flow (for duplicate entries), still output ordered list? what overlooking? what's happening you're testing index after you've reassigned low value, not before you've reassigned value in low value's new position. so, let's consider: xs = [4,3,2,1] = 2 low = [2, 1].min = 1 tmp = xs[i] = 2 now, assign xs[i] = low , means array looks ...
