here's interesting one. i've got 2 compositeviews, categoriesview , categoryview , i've got nested collection of categories, each category may have 0 or more children. i'd render collection category children uses categoriesview itemview , category without uses categoryview . ideally, i'd have categoryview use categoriesview itemview , , vice versa. so: +---------------------------------+ | categoriesview: title | <- 4 children |---------------------------------| | categoryview: item 1 | <- 0 children | categoryview: item 2 | <- 0 children | categoryview: item 3 | <- 0 children | +-----------------------------+ | | | categoriesview: title | | <- 10 children | |-----------------------------| | | | categoryview: item 5 | | ... the issue i'm running can't define categoryview 's itemview property categoriesview because object defined later in script file. causes compositevi...

according windows : graphics hardware vendors must write user-mode display drivers display adapters. user-mode display driver dynamic-link library (dll) loaded microsoft direct3d runtime. user-mode display driver must @ least support direct3d version 9 ddi. e.g. nvd3dum.dll umd directx11 running nvidia. shader compilation happens here directx code called api, before goes kernal mode driver. also umd put code in intermediate representation? (e.g. can driver intermediate language)? opengl has had user-mode component of sort on windows beginning far windows 95 osr2. separation of client/server in architecture made extremely easy do. means lot of client-side api can basic command queuing, validation, resource creation, etc. without having switch kernel-mode. historically, meant draw calls, instance, cheaper in opengl direct3d. in windows vista (wddm) situation changed, wddm mandates user mode driver d3d (this includes d3d9 on vista) serves similar role openg...

example scenario: config files service kept under version control on private github repo. want write playbook fetches 1 of these files on remote node , puts desired location. i can think of several solutions this: do checkout on machine runs ansible ( local_action ) , use copy module do checkout on remote node (with git module), copy files desired location command: cp src dest creates=dest (perhaps handler - when repo has changes pulled) use url module or command: wget https://raw.github.com/repo/.../file creates=file in playbook download file of interest. command module going check if file created different 1 may exist or check file exists? use wget on machine runs ansible ( local_action ) , use copy module push remote node what advantages/disadvantages of these. (if any) of these considered practice. best general solution this? i'll start saying chose 2nd solution our production environment , guarantee 1 thing - works. longer version: solution no. 1...

i made small demo http://html5.by/blogdemo/flexbox/flex-grow-shrink-basis-stackoverflow.html there 2 flex items in flex container flex: 1 2 1000px; flex: 1 1 100px; absolute width of flex container - 500px; finally, can see, width of flex elements are: 421px 79px my question: there way mathematically describe calculated sizes (with formula)? the closest thing formula algorithm in spec: http://www.w3.org/tr/css3-flexbox/#resolve-flexible-lengths i don't think can described in formula. can cover easy cases formula, gets bit more complex (and requires multiple loops of algorithm) when elements have min-width or max-width constraints. side note: flexbox spec make small change flex-grow , flex-shrink behavior, they're treated more percentage when sum less 1. (so e.g. flex-grow: 0.1 never give more 10% of free space, if you're child.) proposal described here: http://lists.w3.org/archives/public/www-style/2013oct/0246.html
