i want run counter on end of website, counting. made javascript counter ( http://directinvent.com/counter/ ) displays desired result, although resets whenever site loaded each individual user. the idea simple enough. run counter end , display result live on front end. ideas on how can done? the same way timer in javascript. store when start counter. recalulate result on every update (request). no need math every 1/10s. if nobody ask, useless. basicly, : long starttime = storetimefor(user); return (currenttimeinsec - starttimeinsec) * incrementationpersec with this, need store starttime each user (in database, file, or in cache if want). on reset, store currenttime again. this how timer in lots of langage because incrementing value every seconds (using sleep(1000)) not precise since thread not running time, not alone on machine ;) edit : on client side, not call server, ask value store , math client same logic. using timeout math on , on every x ms. see how cr

i have flink application implemented following event-sourcing paradigm. both events , commands stored in several kafka topics. the application has 2 startup modes: recovery , production. first, recovery mode used recover application state (a savepoint) events topics. in mode, commands not read @ all. once event topics have been processed, savepoint triggered manually (from command line) , application stopped. then, yarn process started in production mode. in mode application processes both events , commands. i prefer execute process programatically. it, several questions arise... how can application itself: detect kafka sources have been readed? trigger savepoint programmatically? stop , start programmatically? thank you!

i have bash script runs jobs. want able run jobs nice lower priority on server. for example, if executable a.out , can run terminal nice a.out lower job priority. in bash script have variable nice . 1 of following 2 things: # either nice set nice="nice" # or left unset nice="" i run job using "$nice$ ./a.out later in script. this works when nice="nice" not work when nice left set nice="" . one way around use if statement: if [ "$nice" == "nice" ] nice ./a.out else ./a.out fi but becomes 5 or 6 lines of code rather single line. is possible accomplish attempting using nice variable launch executable niceness or no niceness? your first guess almost right. from bash man page (emphasis mine): explicit null arguments ("" or '') retained , passed commands empty strings. unquoted implicit null arguments, resulting expansion of parameters have no

i flatten map associates integer key list of string , without losing key mapping. curious though possible , useful stream , lambda . we start this: map<integer, list<string>> mapfrom = new hashmap<>(); let's assume mapfrom populated somewhere, , looks like: 1: a,b,c 2: d,e,f etc. let's assume values in lists unique. now, want "unfold" second map like: a: 1 b: 1 c: 1 d: 2 e: 2 f: 2 etc. i (or similarly, using foreach ): map<string, integer> mapto = new hashmap<>(); (map.entry<integer, list<string>> entry: mapfrom.entryset()) { (string s: entry.getvalue()) { mapto.put(s, entry.getkey()); } } now let's assume want use lambda instead of nested for loops. this: map<string, integer> mapto = mapfrom.entryset().stream().map(e -> { e.getvalue().stream().? // here can iterate on each list, // best try give me flat map each key, // wouldn't know how flatten.

i'm trying set new vhost did several times before. im using mac , mamp , configure this: /applications/mamp/conf/apache/extra/httpd-vhosts.conf enter: <virtualhost *:80> documentroot "/users/riggi/phpstormprojects/laufschuhsilex/web“ servername laufschuh.local </virtualhost> in /etc/hosts enter: 127.0.0.1 laufschuh.local then restart apache. works , still works many (>20) other local websites. 2 new sites i'm trying add wont work , return 404. any hints on look? i believe quotation mark formatting issue. how close quote @ end of documentroot formatted differently opening quote. make sure formatting correct copy correct quotation mark (the opening quotation mark) , paste on closing mark. can happen when text copy-pasted 1 place another.

i have set of features pre , post intervention values, , i'm running feature selection methods find informative ones , know features improved after intervention. my question ¿is there way know if selected features have bigger or lower value after intervention? i using following scikit-learn methods: - gradientboostingclassifier - linearsvc - variancethreshold - selectkbest - randomforestclassifier - rfecv - extratreesclassifier i guess results of selection show me ones informative, i.e. significant in order differentiate between before , after intervention, cannot find if significance means improved or diminished. scikit-learn provide way this? thank much.

where log object of type eventlog , code... log.entries.cast<eventlogentry>().where(x => x.timegenerated == mydate).tolist(); ...somehow query (my where lambda) prior retrieving of logs performs better? (similarly how ef db query) or first pull entire log memory , filter there? if latter, 'best' (i.e. fast, , more 'performant') use this approach instead (i.e. pass in xml , let query lifting)? i may have worded little awkwardly, i'm asking if first approach mentioned inefficient querying. no not perform better, because log.entries implement simple ienumerable , not iqueryable (like ef example). means not analyze "where" clause expression tree , not convert somehow event query before enumeration. query same as: var result = new list<eventlogentry>(); foreach (eventlogentry x in log.entries) { if (x.timegenerated == mydate) { result.add(x); } } return result;

i have plug-ins defined class libraries in c# (visual studio 2010). each of these plug-ins, after being loaded, should add own menu items main menu of main app, , context-menus other gui components. these plug-ins implemented class libraries, how design, define, , store menus , context-menus? afaik, cannot part of class library designer-editable files. i found article, more complete discussion of question: how can use visual studio designer without form but, surprised why vs developers haven't provided designer standalone visual components (such menustrips , context menus) designed , used freely without dependency on specific form object (i.e., bound many other different forms or other visual components later), , not providing designer these objects seems such big lack in vs.

what efficient way clone javascript object? i've seen obj = eval(uneval(o)); being used, that's non-standard , supported firefox . i've done things obj = json.parse(json.stringify(o)); question efficiency. i've seen recursive copying functions various flaws. i'm surprised no canonical solution exists. note: reply answer, not proper response question. if wish have fast object cloning please follow corban's advice in answer question. i want note .clone() method in jquery clones dom elements. in order clone javascript objects, do: // shallow copy var newobject = jquery.extend({}, oldobject); // deep copy var newobject = jquery.extend(true, {}, oldobject); more information can found in jquery documentation . i want note deep copy smarter shown above – it's able avoid many traps (trying deep extend dom element, example). it's used in jquery core , in plugins great effect.

i'm using datatables jquery plugin , i'm having trouble reference below link can download table json, https://datatables.net/extensions/buttons/examples/html5/customfile.html but in case want save table json in variable send controller use angular or jquery ajax i can using tabletojson library store showing row in current page not full rows { var table = $('#datatable').tabletojson();} if you're using client-side processing, can retrieve data whole table using data() api method. var data = $('#datatable').datatable().data();
