i have collection of tuples of type (boolean, a) i'd transform collection of a . is there known combinator following? .filter(_._1).map(_._2) .collect { case (b, x) if b => x } ( filter isn't operation available on functors in general, depends on mean "i have functor on tuple (boolean, a)")

as explained here , rails creates trap int signals starts. i have rails app starts sinatra app in separate thread. thread.new begin sinatraapp.run! rescue => e puts e.message end end it seems running sinatra app in separate thread causes rails app no longer respond int signals, meaning can't kill via ctrl-c. sinatra app "steals" of int signals. how fix this? possible configure rails app ctrl-c kills both , sinatra app? my sinatra app booting via webrick. found using jruby-based server instead, puma or trinidad (with trap flag set false ), solved problem. this answer helped me find solution.

when start meteor server , navigate default route, see apploading template inside mainlayout (as expected), main template never loads after subscription loaded. i've got simple routes.js file (below) autopublish still turned on. i seeded db , can confirm in browser console subscription there, , there items in services collection. probably missing simple here. /*=================== configure defaults ====================*/ router.configure({ layouttemplate: 'mainlayout', loadingtemplate: 'apploading', notfoundtemplate: 'notfound' }); /*=================== configure routes ====================*/ router.route('/', { // default route name: 'main', template: 'main', waiton: function() { return meteor.subscribe('services'); }, data: function() { return services.find(); } }); i'm guessing not have publication? client waiting "ready" notification publicat

i've been in automated tasks while want allow user create own variable way a = myname = guy (a) = an quite useful please don't use dictionary. same normal variable! you can this: function setvariable(varname, value){ this[varname] = value; } this create variable value , name on window object or on object function attached (calling context). remember objects hash tables, can get/set variables this obj["var1"] = 123; var var1 = obj["var1"]; so it's can set using string name of object member name.

i'm starting first app development , before laying out structure of app need understand how can accomplish complex shapes animations uikit (possibly). i came across animated picture on dribbble , replicate effect in test app, understand how kind of animations accomplished. this animation i'm talking about... firstly thought create keyframe animation (multiple images) , animate it, sounds pretty inefficient. need use uibeizerpath or other core graphics stuff. what suggest me re-create effect? in advance. p.s: possibly if include code snippets, obj-c best choice instead of swift. this site has break down of how you'd accomplish this. basically, use shape layer path entire curve taken middle line during animation. use stroke start , stroke end properties of shape layer transition horizontal line circle. have 2 other shape layers 2 horizontal lines rotate cross.

i edit/manipulate mp4 file without decoding/encoding frames , know if possible. assume have 2 sets of audio/video encoded same parameters. on video side had sequence of frames like: ibppbppbppb , wanted change (where -> inserting) ibppb->ibpp would work ok? i want similar aac audio removing/inserting samples. it possible under circumstances manipulate contents of mp4 file without decoding/encoding frames. instance, can split mp4 file separate files, or concatenate mp4 files. in general, concatenation works if have compatible encoding configurations. for aac audio streams, there no decoding dependencies between audio frames if streams have same configuration, can editing @ mp4 level without problem. for video streams, again same configuration, need concatenate streams starting random access points (closed gop). for these operations, can use mp4box : mp4box -split 10:20 file.mp4 -out file-split-10-20.mp4 will create new file containing 10 seconds. m
