long polling - Liferay Unsychnonized message listener, Send message to page after complete backend operation -

long polling - Liferay Unsychnonized message listener, Send message to page after complete backend operation -

i have implemented liferay asynchronous messagelistener 1 task, takes 20 minutes, reason why using message listener.

but requirement that, after finish back-end process i have show success message user "your info loaded...". don't want utilize ajax polling

please suggest me:

how can stuffs in liferay? there long polling procedure in liferay?

ps: using liferay 6.1.2-ce-ga3

as reference, used doc: https://www.liferay.com/documentation/liferay-portal/6.1/development/-/ai/lp-6-1-dgen09-using-message-bus-0

if don't want utilize ajax, i'd recommend implement "current status". whenever portlet displayed can display if operation still executing or if has completed. how figure out? well, that's part of backend implementation, not portlet level, that's ui.

with this, extend ui status list updated through ajax, incidently not hard, 1 time you're ready go ajax.

on frontend, don't want long polling http requests open through application server - if you're looking this.

there's mechanism liferay's chat portlet , notification portlet use, called poller. however, ajax, don't know if qualifies requirements. check this forum post, note, it's quite old , mentioned bug seems fixed. don't know if developer guide has chapter on well, name i'm confident can find more info

java - How is this below code identifying prime numbers -

java - How is this below code identifying prime numbers -

this code identifies prime numbers given number. if input, 7, returned arraylist have first 7 prime numbers in it.

public static arraylist<integer> calcprime(int inp) { arraylist<integer> arr = new arraylist<integer>(); arr.add(2); arr.add(3); int counter = 4; while(arr.size() < inp) { // 23 , 25 if(counter % 2 != 0 && counter%3 != 0) { int temp = 4; while(temp*temp <= counter) { if(counter % temp == 0) break; temp ++; } if(temp*temp > counter) { arr.add(counter); } } counter++; } homecoming arr; }

my question this. understand code filtering numbers divisible 2 , 3. other numbers, 23 or 25, relying on squares of numbers 4.

i want know how achieving goal. please help me understanding this.

the bit that's doing checking this:

if(counter % temp == 0) break;

it's not relying on squares of numbers @ all. that's telling when stop checking numbers.

first initial set up. knows 2 , 3 primes, adds them list.

then, starting @ 4, checks see if number prime. if is, adds array, if it's not skips out , checks next number.

so "checks see if number prime" done by: first checking if it's divisible 2 or divisible 3:

if(counter % 2 != 0 && counter%3 != 0)

then, starting @ 4 again, doing same check: potential prime (counter) divisible number (temp) ?

if(counter % temp == 0)

if that's case, it's not prime number break command , checks next counter see if that's prime.

if counter not divisible temp increments temp , checks again. when temp big it's not worth checking if it's factor more, algorithm knows counter prime, , adds list.

the temp*temp bit because when it's checking see if number prime, doesn't have check of numbers counter. if temp*temp greater our target, temp factor, other factor has less temp, , has been checked.

php - Dynamically referencing object ID with javascript in Yii -

php - Dynamically referencing object ID with javascript in Yii -

i'm creating tabular input yii, works fine , can save values fields. want add together field next input field, shows value of input field multiplied/divided value. want value updated whenever value in input field changed. input fields created with:

echo $form->textfield($productorder, "[$index]unitsshipped", array( 'onchange' => 'javascript:$("#pallets0").val(this.value/7)' ));

the field next with:

echo $form->textfield($productorder, "unitsshipped", array( 'id' => "pallets".$index, ));

where of above fitted within loop.

the above works, first field, because im statically referencing same field input fields. dont know how can assign dynamically? id pallet field assigned dynamically , if instance set "onchange" reference "pallet1" work, ofc next pallet field.

i've tried concenate strings in javascript, far without luck.

this should work reference current pallets, assuming both fields in same loop index

echo $form->textfield($productorder, "[$index]unitsshipped", array( 'onchange' => 'javascript:$("#pallets'.$index.'").val(this.value/7)' ));

clojure - Documenting functions defined using point-free style -

clojure - Documenting functions defined using point-free style -

when creating library in clojure, it's practice include docstrings , other metadata on each function, e.g.:

(defn ^boolean foo "returns whether x bar." {:added "1.5"} [x] (bar? x))

sometimes (when working higher-order functions) ends beingness easier define function using def (something-that-returns-a-fn), this:

(defn wrapper [f] "some hof, let's prints 'wharrgarbl' , returns fn." (println "wharrgarbl") f) (def foo "prints 'wharrgarbl' , returns whether x bar." (wrapper (fn [x] (bar? x))))

if i'm not mistaken, defining functions in way nullifies advantages of using defn -- namely, docstring beingness printed in nice way includes arities function supports, , ability concisely include attribute map within function definition. right, or there other concise way document functions created via hofs? this:

(defn foo "prints 'wharrgarbl' , returns whether x bar." {:added "1.5"} [x] ((wrapper (fn [y] (bar? y))) x))

but seems little redundant , unnecessarily complicated, i'm defining function of x function of y, applied x. there improve way?

you can add together whatever metadata wish def.

(def ^{:doc "does something." :added "1.5" :arglists '([x]) } foo (wrapper (fn [x] (bar? x))))

the reply here zero, , if multiplied both numbers 100 , did integer modulus be. i'd able using doubles. problem remainder returning number bigger dbl_epsilon - correct(best approximation) way determine whether a or b ~zero?

dbl_epsilon smallest quantity can added 1.0. if number larger 1.0, epsilon number proportionately larger well. multiply dbl_epsilon number threshold.

all: src/ gcc -fpic -shared src/argsort.c -o libsort.so -lm gcc -fpic -shared src/kdtree.c -o libkdtree.so -l./ -lsort -lm

so i'm first building libsort.so. works great. i'm building libkdtree.so uses libsort.so. compilation goes great too, libkdtree.so unusable: here output of ldd libkdtree.so:

if add together directory ld_library_path, works, link there , can utilize library. ld_library_path meant changed ? have no other selection ? mean share code others, , i'd not inquire people go add together .bashrc can run code. think don't understand -l does, since thought manually link library.

can either give me magic method overlooked, or crunch dreams of clean linking ?

i'm rewriting programme used 64 bit words utilize 128 bit words. trying utilize simd sse2 intrinsics intel. new program, uses simd intrinsics, 60% percent slower original when had expected to around twice fast. when looked @ assembly code each of them, similar , same length. however, object code (compiled file) 60% longer.

i ran callgrind on 2 programs, told me how many instruction reads there per line. found simd version of programme had fewer instructions reads same action in original version. ideally, should happen, doesn't create sense because simd version takes longer run.

my question: sse2 intrinsics convert more assembly instructions? sse2 instructions take longer run? or there other reason new programme slow?

i need have column says total total count of each state. can creating column total:

x$total<-1

then

library(data.table x<-data.table(x) x<-x[,total:=sum(total),by=state]

is there better/shorter/efficient way of counting factors in info frame?

you can utilize dplyr (without having create total column):

(edit: @beginner enlightening me existence of n(), can more concise)

library('dplyr') mutate(group_by(x, state), total = n())

@beginner's solution of group_by(x, state) %>% mutate(total = n()) if need go on other manipulations of data. similarly,

x %>% group_by(state) %>% mutate(total = n())

will work, too.

version control - What can be a reason for getting empty svn repository after loading dump file? -

version control - What can be a reason for getting empty svn repository after loading dump file? -

i trying split existing svn repository since has multiple projects in it. want have separate repositories each. lastly step of splitting loading filtered dump file new repository have problem loaded somehow not see them. thought why happens?

thanks beforehand

i see transactions getting committed. how accessing new repository? starting svnserve on directory? using file:///?

do have svnlook on system? can utilize query particular directory. since we're in directory, it's pretty simple:

$ svnlook youngest .

this should print out lastly revision of repository. should agree svnadmin load.

$ svnlook tree .

this should print out entire directory tree of repository.

if doesn't work. seek these:

$ svnlook log .

that print out lastly log message.

$ svnlook changed

prints out changed.

if svnlook tree . doesn't print out anything, it's possible dump filled empty revisions. true if used svndumpfilter filter out transactions didn't like.

if repo have transactions according svnlook, utilize svnserve run local re-create of repo:

$ svnserve -r .

then open window, , seek this:

$ svn log -v svn://localhost

and see if prints out log of transactions.

addendum

i see have, , can see dropped tags, branches, , trunk.

it looks problem didn't specify thought. when specify include a, you're specifying files @ root of repo.

you have:

$ svndumpfilter include < repo.dump > a.dump

what want this:

$ svndumpfilter include trunk/a tags/a branches/a < repos.dump > a.dump

note how have give full path name of directory tree want include. might able this:

$ svndumpfilter include --pattern "*/a" < repo.dump > a.dump

your dump shows of directories excluded svndumpfilter. can utilize verify you're keeping think keeping.

mysql - Extract Values from records with max/min values -

i posted question before , got great reply realize went logic wrong way. given table this:

name|valuea|valueb1|valueb2 bob | 1| 200| 205 bob | 2| 500| 625 bob | 7| 450| 850 bob | 3| 644| 125 ann | 4| 120| 120 ann | 8| 451| 191 ann | 9| 145| 982

i trying max/min values each unique names , ended with

create tablea (select name,max(valuea),min(valuea),max(valueb1,max(valueb2) grouping name)

but gave me (naturally) high/low each of a, b1, b2 e.g.

bob|1|7|200|644|205|850

what looking b1 , b2 values each of lowest , highest values per unique name in other words in above need

bob|1|7|200|205|450|850 ann|4|9|120|120|145|982

which gives me high , low values , b1 , b2 values contained in high , low value records.

(this not duplicate question. lastly question asked , answered how pull high , low values 3 different fields given unique name new table. turns out not needed although first question answered (and marked such). need values 2 fields high , low values of field given name. if @ question see , solutions in fact different)

select tmin.name, tmin.valuea, tmax.valuea, tmin.valueb1, tmin.valueb2, tmax.valueb1, tmax.valueb2 ( select name, max(valuea) valueamax, min(valuea) valueamin `foo` grouping name ) t bring together `foo` tmin on t.name = tmin.name , t.valueamin = tmin.valuea bring together `foo` tmax on t.name = tmax.name , t.valueamax = tmax.valuea;

now, want create custom listview using json data, title , image.

i have tried many examples this. of links given below:

http://qt-project.org/wiki/jsonlistmodel http://developer.blackberry.com/native/documentation/cascades/device_platform/data_access/using_data_source.html

but, still cannot find solutions. can please help me solve issue?

creating list simple plenty task. it's bit harder because want show image internet, have utilize custom class this. download webimageview.cpp , webimageview.h , add together them within /src directory (if want take @ whole project or follow steps).

add next within applicationui.cpp include new class

#include "webimageview.h"

and within applicationui(bb::cascades::application *app) add

qmlregistertype<webimageview>("org.labsquare", 1, 0, "webimageview");

so qml can access class.

this finish working sample of qml:

import bb.cascades 1.2 import bb.data 1.0 import org.labsquare 1.0 navigationpane { id: nav page { container { listview { datamodel: datamodel listitemcomponents: [ listitemcomponent { type: "item" content: container { label { text: listitemdata.title } webimageview { url: "http://adev.si/files/"+listitemdata.picture } } } ] attachedobjects: [ groupdatamodel { id: datamodel grouping: itemgrouping.none }, datasource { id: datasource source: "http://adev.si/files/somedata.json" remote: true ondataloaded: { datamodel.insertlist(data.list1) } } ] } } } oncreationcompleted: { datasource.load(); } }

i trying obtain list of business relationship user has added.

thanks in advance.

edit

when trying forcefulness json response, need quite fussy headers...

in php: curl_setopt($ch, curlopt_httpheader, array( "content-type: application/json", "accept: application/json" ));

works, whereas:

curl_setopt($ch, curlopt_httpheader, array( "content-type : application/json", "accept : application/json" ));

does not.

this api work in sandbox mode, testing purpose can append cobsessiontoken & usersessiontoken in url itself. i.e. like

https://rest.developer.yodlee.com/services/srest/restserver/v1.0/account/summary/all​?cobsessiontoken ="value"&usersessiontoken="value".

note api using method while rest of apis using post method of http. while, if using site based aggregation should utilize getallsiteaccounts api.

javascript - Drag Range Slider - How to add step and an element (comma) to the output -

i'm using dragdealer.js , have got far:

fiddle

while dragging through slide, gives output,

question: 1) how can add together "," (comma) output after hundreds unit while dragging?

-> right now:-$ 4023 -> required output:- $ 4,023

2) how implement step shows output in multiple of 100?

-> required output:- $ 4.100 (multiple of 100)

here code:

js:

$(function() { new dragdealer('just-a-slider', { animationcallback: function(x, y) { $('#dragvalue').text(math.round(x * 15000)); } }); var availheight = $('.content-body').outerheight() - $('.content-mask').outerheight(); new dragdealer('content-scroller', { horizontal: false, vertical: true, yprecision: availheight, animationcallback: function(x, y) { $('.content-body').css('margin-top', -y * availheight); } }); });

you can utilize .replace(/(\d)(?=(\d\d\d)+(?!\d))/g, "$1,") add together in comma, , if split base of operations 100, ( = 150 ), step through in 100's , can append additional 0's onto text output required.

sqlite3 - unicode() for all characters of a query -

sqlite3 - unicode() for all characters of a query -

the unicode() function in sqlite accepts 1 parameter; if execute query:

select unicode(text) table

and suppose table has 1 row abc; result be: 97 numeric unicode code a character; if want numeric unicode code characters in result of query? such thing possible within sqlite?

(i know can numerical codes out of sqlite within environment of programming language; i'm curious if such thing possible sql command within sqlite or not.)

sqlite not have looping constructs; doing in programming language much easier.

in sqlite 3.8.3 or later, utilize recursive common table expression:

with recursive all_chars(id, u, rest) ( select id, unicode(text), substr(text, 2) mytable union select id, unicode(rest), substr(rest, 2) all_chars rest <> ''), unicodes(id, list) ( select id, group_concat(u) all_chars grouping id) select * unicodes

the id required merge values of single source row together; doing single, specific row in mytable easier.

Monitor google search in Java -

for master thesis need maintain track of google searches users perform. should web project. @ first want setup server (that acts proxy) monitor actions (search queries) performed user. server should deliver google search page. need maintain track of input users create , corresponding results returned google well.

my questen now.. how should start?

i not sure webserver use. should utilize tomcat / jetty / or else? java server faces or servlets? worked jsf long time ago not sure whether decision utilize it. the server should deliver google search page. here idea: user connects server. server "reads" google page , returns (the source code) user. think of using listener on default search field monitor search queries of users. how possible monitor results returned google? google site uses javascript guess. when user makes input straight sent google , results straight shown on webpage webserver not see connection between client , google services.

the main thought monitor search query , corresponding search results.

i need help , ideas started. little part of thesis. not want start 0 during editing time want create sure create right choices before start.

thank in advance... best regards.

you utilize netty proxy , filter , log search queries. 1 time again why utilize java? describe wan't play man-in-the-middle , manipulate/log http traffic.

a quick google search came python: https://code.google.com/p/proxpy/

edit: , similar in java https://github.com/adamfisk/littleproxy

Error in Android Studio Build -

Error in Android Studio Build -

my system: windows 7, android studio v0.5.2, jdk v1.7.0_25

i've seen discussed several different places none of solutions seem work me (or haven't tried right combination).

the problem when build project android studio , seek run error: **"error:gradle: execution failed task ':app:packagedebug'.

class org.bouncycastle.asn1.asn1primitive overrides final method equals.(ljava/lang/object;)z"**

this seems have bouncy casstle dll's. i'm leary of changing things in jdk prepare - if need be.

does have definitive solution (and, addressed android studio team? poking around , deleting dlls scheme can't end solution).

here's list of of bc* files on system:

c:\program files\java\jdk1.7.0_25\jre\lib\ext\bcprov-ext-jdk15on-1.46.jar c:\program files\java\jdk1.7.0_25\bin\bcprov-ext-jdk15on-1.46.jar c:\users\scott.coleman\desktop\bcprov-ext-jdk15on-1.46.jar c:\program files\java\jre7\lib\ext\bcprov-ext-jdk15on-1.46.jar c:\eclipse\configuration\org.eclipse.osgi\bundles\270\1\.cp\lib\bcprov-ext-jdk15on-148.jar c:\program files\charles\lib\bcprov-jdk14-143.jar c:\users\scott.coleman\appdata\local\temp\rar$exa0.979\gradle-1.10\lib\plugins\bcprov-jdk15-1.46.jar c:\users\scott.coleman\.gradle\wrapper\dists\gradle-1.10-all\1t6fjo8i1s1ddu1afn3ioaglko\gradle-1.10\lib\plugins\bcprov-jdk15-1.46.jar c:\users\scott.coleman\desktop\bcprov-jdk15on-1.48.jar c:\android\android-sdk\tools\lib\bcprov-jdk15on-1.48.jar c:\eclipse\configuration\org.eclipse.osgi\bundles\247\1\.cp\libs\bcprov-jdk15on-1.48.jar c:\program files (x86)\android\android-studio\plugins\android\lib\bcprov-jdk15on-1.48.jar c:\users\scott.coleman\.gradle\caches\modules-2\files-2.1\org.bouncycastle\bcprov-jdk15on\1.48\960dea7c9181ba0b17e8bab0c06a43f0a5f04e65\bcprov-jdk15on-1.48.jar

somehow, broken library beingness loaded in jre. can print out jar beingness loaded bouncycastle library , seek deleting or replacing it.

add next snippet @ origin of build.gradle file

class klass = org.bouncycastle.asn1.bc.bcobjectidentifiers.class; url location = klass.getresource('/'+klass.getname().replace('.', '/')+".class"); println location.touri().tostring();

c# - Dispatcher Task /Action Completion -

c# - Dispatcher Task /Action Completion -

i have application fetches info form server , gives result user . info beingness fetched quite big blocks ui sometime. using dispatcher create asynchronous.

here code snippet :-

private void getdata(object sender, routedeventargs e) { list<result> data=new list<result>; dispatcherobject obj= dispatcher.begininvoke(dispatcherpriority.background,(threadstart)delegate { info =data.fetch_data(id, name, url); }); if(obj.completed){ messagebox.show("done!"); } }

but code gives error saying

"cannot implicitly convert type 'system.windows.threading.dispatcheroperation' 'system.windows.threading.dispatcherobject' ".

is there anyway user can notified when background task gets completed?

edit :-

here async/await code

private async void getdata(object sender, routedeventargs e) { task<list<result>> t =task<list<resultsummary>>.factory.startnew(() => data==data.fetch_data(id, name, url)); await t; }

but gives error "" calling thread cannot access object because different thread owns it."

calling dispatcher.begininvoke not enable perform asynchronous actions on background thread unless initialised dispatcher object on background thread. so, instead of using dispatcher want, in order fetch info on background thread , pass info background thread ui thread, can utilize task class.

task.factory.startnew((func<yourdatatype>)delegate() { // fetch info on background thread here (return yourdatatype, whatever is) homecoming dataaccessclass.getdata(); }).continuewith((task<yourdatatype> task) => { // update controls result on ui thread here youruiproperty = task.result; }, taskscheduler.fromcurrentsynchronizationcontext());

obviously, you'll need replace yourdatatype type whatever info type is.

asp.net mvc - Client or server validation doesn't work with Data Annotations -

asp.net mvc - Client or server validation doesn't work with Data Annotations -

i'm developing mvc 4 application entity framework 6 , encountered problem info annotations. no matter annotation use, isn't validate. i'm using next view model render form:

public class userviewmodel { [required(errormessage = "first name required")] [display(name = "first name")] [stringlength(100, minimumlength = 2)] public string firstname { get; set; } ... }

in view:

@html.labelfor(m => m.firstname) @html.editorfor(m => m.firstname) @html.validationmessagefor(m => m.firstname)

and gets rendered:

<label for="firstname">first name</label> <input class="text-box single-line" id="firstname" name="firstname" type="text" value="" /> <span class="field-validation-valid" data-valmsg-for="firstname" data-valmsg-replace="true"></span>

when click submit button client validation doesn't triggered , in controller modelstate.isvalid true.

update:

controller:

[httpget] public actionresult edit(int? id) { var model = _userservice.getuserbyid(id); homecoming view(model); } [httppost] public actionresult edit(userviewmodel model) { if (modelstate.isvalid == true) { _userservice.save(model); homecoming view(model); } homecoming view(model); }

the problem post controller, map user object, not userviewmodel. 1 of reasons server-side validation not triggered.

as client-side validation, i'm not sure, same error - view based on user type, rather on userviewmodel.

so controller should this:

[httpget] public actionresult edit(int? id) { var model = _userservice.getuserbyid(id); var viewmodel = new userviewmodel() { firstname = model.firstname, lastname = model.lastname, // other properties }; homecoming view(viewmodel); } [httppost] public actionresult edit(userviewmodel viewmodel) { if (modelstate.isvalid == true) { var model = new user() { firstname = viewmodel.firstname, lastname = viewmodel.lastname, // other properties }; _userservice.save(model); homecoming view(model); } homecoming view(model); }

and top of edit.cshtml should have @model userviewmodel.

hope helps

Which is more widely used and acceptable about C operators? -

though 4 * (num / 6)is more easy understand, num / 6 * 4 right because operator * , / in same priority, , associativity left right.

but, better, , more used / acceptable?

although both correct, parenthesis friend. stick it. paranthesization makes look easier understand fellow programmers reduces chances of logical errors specially when not sure precedence of operators.

in above want outer bring together on tbl_cust_products , tbl_received_sms tables. have tried union outer join here. searched , find out mysql not back upwards direct outer join other big database handlers.

if making error utilize union or logic plz help me accomplish this..

edited problem: in tbl_received_sms has 7,734 records , in tbl_cust_products has 3 records.. need total 7737 records in result. if utilize union 3 records, if utilize union all 7737 records fields of records null.

the problem queries returns columns tables tcp (tbl_cust_products), tc (tbl_customer), tb (tbl_brand), tgt (tbl_gadget_type), tm (tbl_model), ttt (tbl_ticket_type) , trs (tbl_registration_source).

all these columns rely on record existing on tcp (tbl_cust_products) table, either come table or tables left outer joined record on table.

any row has matching record on tcp (tbl_cust_products) returned first query. 2nd query homecoming of these has matching record on trsm (tbl_received_sms). returned both have 1 occurrence eliminated union.

the farther issue row returned 2nd query there no matching record on tcp (tbl_cust_products) have null in fields part of query returns (as fields depend on match on tcp (tbl_cust_products)). union eliminate 1 of rows, eliminates duplicates , rows identical (ie, nulls).

if want output add together column trsm (tbl_received_sms) columns returned. trsm.cust_prod_id 1 try.

edit bit more details explain unions.

take illustration heavily simplified version of query:-

select tcp.id, tc.name tbl_cust_products tcp left bring together tbl_received_sms trsm on tcp.id = trsm.cust_prod_id left bring together tbl_customer tc on tcp.cust_id=tc.id union select tcp.id, concat(tc.firstname,' ',tc.lastname) cust_id tbl_cust_products tcp right bring together tbl_received_sms trsm on tcp.id = trsm.cust_prod_id left bring together tbl_customer tc on tcp.cust_id=tc.id

say tables contain following

tbl_cust_products id name cust_id 1 5 2 b 6 tbl_received_sms id cust_prod_id info 3 2 c 4 3 d 5 4 e tbl_customer id name 5 fred 6 burt

the first query homecoming both records tbl_cust_products, 1 of matched against tbl_received_sms:-

id name 1 fred 2 burt

the 2nd query find 3 records tbl_received_sms, 1 of matched against tbl_cust_products. records unmatched have null in both returned fields (as there no matching record on tbl_cust_products value of field there null, , same value of field tbl_customer match non existant record tbl_cust_products). record matches populated:-

id name null null null null 2 burt

the union merge these 2 lots together,

id name 1 fred 2 burt null null null null 2 burt

but eliminating duplicates, hence:-

id name 1 fred 2 burt null null

the above line h meant calculate impulse response, python code:

gives me error indexerror: index 256 out of bounds axis 0 size 256. know has indexing s array, how can prepare it?

remember python zero-indexed, while matlab 1-indexed. note matlab piece notation includes endpoint, whereas python piece notation excludes endpoint.

s(length(s):-1:1) mutual matlab idiom reversing vector. python has nicer syntax: s[::-1]. direct translation s[len(s)-1:-1:-1].

python - Constructing 3D Pandas DataFrame -

python - Constructing 3D Pandas DataFrame -

i'm having difficulty constructing 3d dataframe in pandas. want this

a b c start end start end start end ... 7 20 42 52 90 101 11 21 213 34 56 74 9 45 45 12

where a, b, etc top-level descriptors , start , end subdescriptors. numbers follow in pairs , there aren't same number of pairs a, b etc. observe a has 4 such pairs, b has 1, , c has 3.

i'm not sure how proceed in constructing dataframe. modifying this illustration didn't give me designed output:

import numpy np import pandas pd = np.array(['one', 'one', 'two', 'two', 'three', 'three']) b = np.array(['start', 'end']*3) c = [np.random.randint(10, 99, 6)]*6 df = pd.dataframe(zip(a, b, c), columns=['a', 'b', 'c']) df.set_index(['a', 'b'], inplace=true) df

yielded:

c b 1 start [22, 19, 16, 20, 63, 54] end [22, 19, 16, 20, 63, 54] 2 start [22, 19, 16, 20, 63, 54] end [22, 19, 16, 20, 63, 54] 3 start [22, 19, 16, 20, 63, 54] end [22, 19, 16, 20, 63, 54]

is there way of breaking lists in c own columns?

edit: construction of c important. looks following:

c = [[7,11,56,45], [20,21,74,12], [42], [52], [90,213,9], [101, 34, 45]]

and desired output 1 @ top. represents starting , ending points of subsequences within sequence (a, b. c different sequences). depending on sequence itself, there differing number of subsequences satisfy given status i'm looking for. result, there differing number of start:end pairs a, b, etc

first, think need fill c represent missing values

in [341]: max_len = max(len(sublist) sublist in c) in [344]: sublist in c: ...: sublist.extend([np.nan] * (max_len - len(sublist))) in [345]: c out[345]: [[7, 11, 56, 45], [20, 21, 74, 12], [42, nan, nan, nan], [52, nan, nan, nan], [90, 213, 9, nan], [101, 34, 45, nan]]

then, convert numpy array, transpose, , pass dataframe constructor along columns.

in [288]: c = np.array(c) in [289]: df = pd.dataframe(data=c.t, columns=pd.multiindex.from_tuples(zip(a,b))) in [349]: df out[349]: 1 2 3 start end start end start end 0 7 20 42 52 90 101 1 11 21 nan nan 213 34 2 56 74 nan nan 9 45 3 45 12 nan nan nan nan

javascript - Can I declare a non-global variable to store asynchronous values? -

i have multiple javascript files. have js function runs upon load contains multiple ajax calls. each ajax phone call performs callback (as increments synchronous counter):: myarray.push('somevalue');

so can verify when ajax calls (for js file) have finished.

is there way can away not declaring myarray global variable, while allowing asynchronous callbacks force array?

if want execute code after set number of ajax requests have completed, utilize $.when.

if using myarray solely know when requests finished, can remove it. if using store result of each request, can maintain in same scope requests , access in done handler. seek this:

var myarray = []; var ajax1 = $.ajax({ url: '/foo/', success: function(data) { myarray.push(data); }); }); var ajax2 = $.ajax({ url: '/bar/', success: function(data) { myarray.push(data); }); }); $.when(ajax1, ajax2).done(function() { // both requests finish // myarray contain info of both requests @ point... (var = 0; < myarray.length; i++) { console.log(myarray[i]); } });

javascript - How to add boolean attributes to directive? -

in html, there attributes selected attribute:

<option selected>this alternative selected</option>

it's either nowadays or not present, translates on/off (boolean).

i can't find way create attribute angularjs directive. there way?

an illustration be:

<modal ng-show="modal.show" with-backdrop> // "with-backdrop" boolean attribute.

it's going different depending on you're doing. in example, want know alternative selected. found checking model <select> see what's in it. example:

<select data-ng-model="user.defaultthing" data-ng-options="thing.id thing.name thing in thingcollection"> <option value="">none</option> </select>

with setup, time selection changed, thing.id stored in user.defaultthing.

nb: 'none' alternative have there, allows null selection.

now, if looking see if checkbox checked, it's similar you'd see what's in model it's tied to.

<input type="checkbox" data-ng-model="form.someoption">

when go process form, see if form.someoption true or false.

i want pass above value of routearr , routearr2 dynamically. have provide route path , fence path before page loads or there way through can pass array both dynamically ?

the mapobject need @ minimum 1 coordinate point , 2 coordinates shape. can init objects routearr1 , routearr2 , alter afterwards routepolyline.set("path", strip); strip new strip.

javascript - Adding and removing click/hover event handlers jQuery -

javascript - Adding and removing click/hover event handlers jQuery -

run issues mixing click , hover events.

clicking inactive li element toggles active class , binds hover event. hovering on active element displays hidden block (span.rate) clicking hovered element supposed hide it, remove hover event , toggle active class on parent no longer 'active'.

clicking hovered event not remove events , toggle active. there other logic in there regarding mutually exclusive options, works fine though.

jsfiddle of how sits together:

http://jsfiddle.net/65yy3/15/

current js:

ps = { pstoggle: 0, init: function () { $(document).ready(function () { $('.example li a)').on('click', function(e) { e.preventdefault(); var = $(this); if (that.parent().hasclass('paired')) { if (rm.pstoggle === 0) { that.toggleclass('active'); that.find('.rate').fadetoggle(50); rm.pstoggle = 1; } else { if (that.hasclass('active')) { that.toggleclass('active'); that.find('.rate').fadetoggle(50); rm.pstoggle = 0; } else { $('.paired a').toggleclass('active'); that.find('.rate').fadetoggle(50); //call message function } } rm.pcontrol(); } else { that.toggleclass('active'); that.find('.rate').fadetoggle(50); rm.pcontrol(); } }); }); }, pcontrol: function () { //unbind events command items excluding 1st item. $('.example li a').off('hover'); $('.example li .rate').off('click'); $('.example .active').each(function(i) { $(this).on('hover', function() { $(this).find('.rate').fadetoggle(50); }); }); $('.example li a.active .rate').on('click', function() { //remove hover/hide , toggle active state $(this).off('hover'); $(this).hide(); $(this).parent().toggleclass('active'); rm.pcontrol(); //rebind new active classes }); }

};

ps.init();

check below demos.

both click events getting fired ,.rate kid of a.

$('.example li a.active .rate').on('click'... ,

$('.example li a').on('click'...

so can either remove click on .rate. demo1

or add together e.stoppropagation(); kid stop event bubbling parent child. demo2

$('.example li a.active .rate').on('click', function(e) { e.stoppropagation(); //remove hover/hide , toggle active state $(this).off('hover'); $(this).hide(); $(this).parent().toggleclass('active'); ps.pcontrol(); //rebind new active classes });

but foo should there if status true.

if not, should just: someurl.com/1111

<%= link_to 'my link', your_path(:foo => ("clown" if your_condition)) %>

in exemple, :param equals "clown" if your_condition true, else :param nil , if param nil, ruby don't consider there parameter , ignore it.

php - Transform one class to another class -

php - Transform one class to another class -

i want scheme of class versioning allow 1 scheme talk scheme in way future changes wouldn't impact what's in place.

let's scheme , scheme b talk each other via rpc calls. business requirements alter , scheme , b need changed future development while beingness backward compatible

the next work:

class base_version { public static function getversion($version = 1) { $versionclass = 'version_'.$version; homecoming new $versionclass(); } } class version_1 { public function sayhello() { echo "hello version 1\n"; } } class version_2 { public function sayhello() { echo "hello version 2\n"; } } $obj = base_version::getversion(); $obj->sayhello(); $obj = base_version::getversion(2); $obj->sayhello();

i don't static instancing however. this, except know can't reassign $this.

class base_version { public function __construct($version) { $versionclass = 'version_'.$version; $this = new $versionclass(); } } $obj = new base_version(); $obj->sayhello(); $obj = new base_version(2); $obj->sayhello();

how can accomplish this?

i think abstract class defined constructor can close that.

let's remind abstract class need have @ to the lowest degree 1 abstract function, can have 'concrete'[sic]* functions same each inheriting class. abstract classes can't instanciated, children.

here is:

abstract class base_version {function __construct($version) {$this->version = $version; switch ($this->version) {case 1: // build class 1 break; case 2: // build class 2 etc. break; default: // careless programmers won't define constructor in future break;}} function version() {return $this->version;} abstract function sayhello();}

this base of operations abstract class. if business requirements change, can add together cases here new classes in constructor.

class greeter extends base_version {function sayhello() {return 'this old version' . $this->version(); }} class new_greeter extends base_version {function sayhello() {return 'hello version ' . $this->version(); }}

the point of abstract class here class not throw errors if extending abstract class, must implement function sayhello().

that way, whoever ever makes class extending base_version won't break programme because objects have @ to the lowest degree functions defined abstract in base of operations class.

so there iss, way define classes can alter in time without breaking way older ones work

$obj = new greeter(1); $obj ->sayhello(); $obj2 = new new_greeter(2); $obj2->sayhello(); 'concrete' in c++ has specific meaning, don't want offend using here if it's not same

asp.net mvc - React.NET uncaught TypeError: undefined is not a function -

asp.net mvc - React.NET uncaught TypeError: undefined is not a function -

i trying larn reactjs , found react.net.

followed tutorial on author's website alter beingness mvc 5 app instead of mvc 4.

here jsx:

/** @jsx react.dom */ var commentbox = react.createclass({ render: function() { homecoming ( <div classname="commentbox"> <h1>comments</h1> <commentlist data={this.props.data} /> <commentform /> </div> ); } }); react.rendercomponent( <commentbox data={data} />, document.getelementbyid('content') ); var commentlist = react.createclass({ render: function() { var commentnodes = this.props.data.map(function (comment) { homecoming <comment author={comment.author}>{comment.text}</comment>; }); homecoming ( <div classname="commentlist"> {commentnodes} </div> ); } }); var commentform = react.createclass({ render: function() { homecoming ( <div classname="commentform"> hello, world! commentform. </div> ); } }); var info = [ { author: "daniel lo nigro", text: "hello reactjs.net world!" }, { author: "pete hunt", text: "this 1 comment" }, { author: "jordan walke", text: "this *another* comment" } ];

it gives error:

uncaught typeerror: undefined not function

any clues on one?

regards.

there 3 steps in snippet.

first, define commentbox:

var commentbox = react.createclass...

second, render commentbox , commentlist:

react.rendercomponent...

third, define commentlist:

var commentlist = react.createclass...

so, problem commentlist rendered before commentlist defined. if lastly 2 steps switched around work fine. commentlist class needs defined before can rendered.
