there have been similar questions before, have not found altogether clear answer this: say have basic line graph composed of valuelinea 20 vertices. i want transition line valuelineb 256 vertices. the x domain remains same, y domain. assume valuelinea , valuelineb evenly distributed across x domain (time). how transition occur between valuelinea , valuelineb such there no horizontal animation? the code below transition between valuelinea , valuelineb , transitions squeezes valuelinea first 20 vertices of valuelineb . var trends=svg.append("path") .attr("class", "line") .attr("d", valuelinea(dataa)); trends .transition() .duration(3200) .attr("d", valuelineb(datab)) ; i've found few posts similar ( here , here ), it's still not entirely clear me how perform seems basic operation. there isn't easy solution, i'm afraid. here pointers

my current compiler doesn't support future header, , i'm unable update on android, compiler wrapped in app. because of this, decided try make own simple future class. have of laid out, can't figure out how return value thread (as seems beyond intended use). pass future class functor contains it's own return holder variable retrieved later, that's little limiting, because wanted pass have derived original functors class, , not function. is there way achieve this? i'm assuming standard future header doesn't use black magic it. use "different version" of threads allow receive value back? (it's not old not compatible threading, has issues future header reason) thanks i think writing own simple future class you're on right way. code like? i'm not sure if understand statement: i pass future class functor contains it's own return holder variable retrieved later, that's little limiting, because wanted pass ha

i've decided take plunge , make next blog in ghost 0.4.1 rather wordpress. client has small amount of traffic, , easy never need load balanced across multiple servers. my question is: ghost can configured listen port, can use web server listening port 80? there problem doing this? followup question: every example shows hosting apache or nginx, there security or performance reason this? thanks in advance! you can run ghost on port 80 recommended run ghost on port 2368 , proxy requests through apache or nginx. you can checkout this article example of how install ghost , run on port 80. highly recommend reading through this article , proxying requests through nginx. ghost running on port 2368 can use low privileged user start ghost , therefore not have use higher privileged user start ghost.

(message "%s" load-path) , (describe-variable 'load-path) give different results. several more path "/users/updogliu/.emacs.d/elpa/flycheck-20140323.828" appeared in latter. how can make (require 'flycheck) use "describe" 1 load-path ? to setup flycheck properly, not need require flycheck. instead, enable global flycheck mode: (add-hook 'after-init-hook #'global-flycheck-mode) this enable flycheck supported languages. to make (require 'flycheck) work in init.el , need add (package-initialize) @ very beginning of init.el . (package-initialize) sets emacs' built-in package system, includes adding packages load-path . emacs calls automatically, after init.el has been processed, hence use of after-init-hook enable flycheck. if added message call init.el without calling (package-initialize) first, you'll hence see standard load-path without of packages. to make packages available in i

so have xampp setup zurmo 2.6.5 running on it. works charm. speed @ pulls contacts, goes through pages, etc considerably fast. have 2 gb ram , web app runs on it. can call dedicated guess. problem arises when attempt export decent amount of data excel (csv option available). e.g, tried exporting 200-odd rows of data , timed out due max_execution_limit parameter. increased first around 300 600, , 1200. script keeps running though there no end :-/. surprisingly, when first apply filter (not many, one), takes around 10-15 seconds display first 10 records. indicates query executes within time limits. have memcached installed, suggest alleviate performance issues. i checked zurmo's forums , net in general, unfortunately did not single hit reference issue. can fellow zurmo developer / power user me resolved? much appreciated. thanks.

i have mysql procedure collecting data 3 tables: dossier courrier courrier_concerne_dossier simply can't use select * from... need every dossier_str separated (one dossier_str in each column , in 1 big result set).

suppose have array of objects: data = [{id:1, name="a"}, {id:2, name="b"}, {id:3, name="c"}, ....] and have 2 arrays: selecteddata = [{id:1, name="a"}, {id:3, name="c"}] and selecteddataids = [1,3] i want these 2 arrays bound each other. e.g. when selecteddataids = [1] then selecteddata = [{id:1, name="a"}] and vice versa. you put both of arrays service , control update of arrays through method calls. check out plunkr here . it's cursory attempt think use starting point.

i have been @ 2 weeks now. believe have come close, can't quite final product work. have functionality similar email in app. instead of email addresses, uses phone numbers. gmail app on android able use multiautocompletetextview with chips display recipient email addresses. want do. through research , trials, able create multiautocompletetextview, without chips. there number of questions , answers here on same subject. invariably, none of ones find has example binds data user's contact book multiautocompletetextview. examples see use own made simple arrays, if final step trivial. final step stuck. each time try bind contact book multiautocompletetextview chips, code fails. question quite extremely specific: how bind contact book multiautocompletetextview chips? context, have read chips widget in android application , bunch of other articles , responses besides. aware of specific use case? gmail use case? edit following code use https://github.com/splitwise/tokenautoc

is possible select parts of text , open in different buffer different mode? fore example, if work in ess mode (syntax highlighting r), astring <- '<form> <input type="checkbox" id="foo", value="bar"> </form>' if text within single quotes selected, edit in new buffer html mode (similar org-src-lang-modes in orgmode ). here 1 method of handling issue using narrow-to-region -- example contemplates point (cursor) somewhere between single quotes when typing m-x narrow-to-single-quotes . simple two-line function can used exit -- (widen) (ess-mode) ; or, can fancy recursive-edit . of course, not same opening text in new buffer. similar functionality can used copy region new buffer, assuming original poster may want incorporate edited text primary buffer.

i'm programming nexus 7. in program reach point want user select wifi network use (either preconfigured or choice create new one). how can bring dialog programmatically? in order access wi-fi list, may first need use wi-fi permissions. wi-fi must turned on first before wi-fi scan can provide list of results. my guess is: access_wifi_state i think easiest approach launch appropriate intent. action_pick_wifi_network http://developer.android.com/reference/android/net/wifi/wifimanager.html#action_pick_wifi_network (may wish see: action_wifi_settings)

suppose have dataset a: id geogkey 1 1 b 1 c 2 w 2 r 2 s and dataset b: id temp date 1 95 1 1 100 2 1 105 3 2 10 1 how merge these 2 datasets 3 records each geogkeys id=1 , 1 record each geogkeys id =2? assuming want cartesian join, best off doing in sql, if it's not big: proc sql; create table c select * a,b a.id=b.id ; quit; the select * generate warning id variables overwriting; if that's concern, explicitly spell out select ( select a.id, a.geogkey, b.temp, b.date ).
