it seem if there "max-width" (or having similar effect) set on div somewhere, there isn't, far can tell. yet bottom of container spills out on bottom edge so: why that, , how can prevent it? update what happening here html5 section elements being dynamically (programmatically, via jquery) added tab's content area. pertinent code: html: <div id="tabs" class="content-wrapper"> <ul> <li><a href="#tab-books">books</a></li> <li><a href="#tab-movies">movies</a></li> <li><a href="#tab-music">music</a></li> </ul> <div id="tab-books"> <select id="bookdropdown"> <option value="pulitzer">pulitzer</option> <option value="nbcc">national book critics circle</option> <optio

i see code in underscore.js. here is, alias applied: tostring = objproto.tostring, however, use tostring accessible directly this, w/ out using above code @ all. tostring() try out in console works fine. try out in direct code , works fine well. guess older browsers may not have accessible in way. how can further? caniuse not not have information on it. google pulls nothing useful in first 10 or hits. because on object.prototype , accessible global objects inherit object ( inherit, not global objects ), such number. but point is, is accessible directly out having use global object instance @ all. tostring(some_var); here 1 so q/a suggests window.tostring not supported in browsers , why is. global objects inherit object, that's wrong assumption, global objects host objects , can inherit whatever want or not inherit @ all. code example doesn't work in ie10. the particular tostring method stored on object.prototype 1 returns in

so, question states, purpose of cs , ip registers in intel's 8086 i found explanation: code segment (cs) 16-bit register containing address of 64 kb segment processor instructions. processor uses cs segment accesses instructions referenced instruction pointer (ip) register. cs register cannot changed directly. cs register automatically updated during far jump, far call , far return instructions. and ip: instruction pointer (ip) 16-bit register. i don't understand means, if provide more "vivid" explanation, great :) since ip 16 bit means can have 64k instructions (2^16), wasn't in 80s. expand address space have second register addresses 64k blocks. consider cs:ip 1 32 bit register capable of addressing 2^32 bytes...ie 4g on processor uses 32 bit addresses. 8086 using 20 bits of addresses, access 1m of memory.

given dictionary of lists vd = {'a': [1,0,1], 'b':[-1,0,1], 'c':[0,1,1]} i want add lists element wise. want add first element list first element of list b vice versa complexity cannot rely on labels being a, b, c. can anything. second length of dictionary variable. here 3. 30. the result need list [0, 1, 3] in short: >>> map(sum, zip(*vd.values())) [0, 1, 3] explanation given dictionary: >>> vd = {'a': [1,0,1], 'b': [-1,0,1], 'c': [0,1,1]} we can get values : >>> values = vd.values() >>> values [[1, 0, 1], [-1, 0, 1], [0, 1, 1]] then zip them up: >>> zipped = zip(*values) >>> zipped [(1, -1, 0), (0, 0, 1), (1, 1, 1)] note zip zips each argument; doesn't take list of things zip up. therefore, need * unpack list arguments. if had 1 list, sum them: >>> sum([1, 2, 3]) 6 however, have multiple, can map on it: >>> map

after writing matrix class represents whole matrix in 2 1d-buffers using this implementation , i've reached matrix maltiplication part in project , inclined cache-friendly-optimizations now. stumbled upon 2 options(question in lower part of page): 1)selecting blocked/tiled sub-matrices in multiplication time. done in c++ dll function, no function overhead. since code more complex, additional optimizations harder apply. 2)building matrix class sub matrix classes(smaller patches) multiplication done on sub-matrix classes. object oriented approach leaves space additional optimizations sub-matrices. object headers , padding behavior of c# can overcome critical strides? function overhead can problem after calling many times instead of few times. example matrix multiplication: c=a.b 1 2 3 4 used 1 2 3 4 4 3 4 2 4 3 4 2 1 3 1 2 1 1 1 2 1 3 1 2 1 1 1 2 b 1 1
