i have table formatted: fcst_month | idx1 | idx2 | idx3 | val1 | val2 | ... | valn i sum of of 'val's each fcst_month. seems way of doing transpose table using tablefunc crosstab() ( https://www.postgresql.org/docs/9.3/static/tablefunc.html ) , passing in column particular fcst_month, reading docs , other examples on so, i'm not understanding how use function achieve goal. could give me example of crosstab() achieve or similar task? or perhaps suggest alternative achieving goal? you can unpivot table using json functions row_to_json() , json_each_text() . additionaly, use with ordinality column numbers. example: create table a_table (fcst_month int, val1 int, val2 int, val3 int); insert a_table values (1, 10, 20, 30), (2, 40, 50, 60); select fcst_month, ordinality, key, value a_table, json_each_text(row_to_json(a_table)) ordinality; fcst_month | ordinality | key | value ------------+------------+------------+------- 1 | ...

while understand angular 2's animate used animate transition between states in fixed time, not convenient. in case, have slide-able element, wish animate based on how far have moved default position. is, want provide handler dynamically with, example float number between 0 , 1 representing how far along animation should be. can angular 2 framework handle this? can perhaps, somehow, bypass default animate(time) property , , directly call underlying function changes css? i'm not 100% clear on problem, don't think you're asking possible angular animations. angular's animations built on top of web animation api, streamlined means of interacting css animations. css animations defined keyframes + durations (see https://css-tricks.com/almanac/properties/a/animation/ ). theoretically, create complex set of keyframes "stepped through" based on position of slide-able element, hack , not you're asking for. to accomplish goal, think you'l...

my index datetime string format '%m/%d/%y' ('09/26/2007') when try convert index datetime index using pd.to_datetime function pd.to_datetime(df.index) , got error message outofboundsdatetime: out of bounds nanosecond timestamp: 1-01-01 00:00:00 it looks pandas can't detect right string format, how can convert index datetime index? thanks the of error message, appears may have string '1/1/0001' in index. example, df = pd.dataframe([1,2], index=['09/26/2007', '1/1/0001']) pd.to_datetime(df.index) raises outofboundsdatetime: out of bounds nanosecond timestamp: 1-01-01 00:00:00 this error arises because datetimeindex uses array of numpy datetime64[ns] s can not represent date 0001-01-01. datetime64[ns] dtype can represent dates in range [1678 ad, 2262 ad] . there pandas github issue discussing limitation. for now, recommended solution use periodindex instead of datetimeindex: df = pd.dataframe([1,2], index=[...

i have big problem run activiti-explorer when try access: http://localhost:8080/activiti-explorer/ tomcat shows me http status 404 - requested resource not available. i'm don't have idea why dosen't work. can me? this have done on pc: i'm using 5.19.0 version of activiti-explorer 7.0.63 tomcat jdk 1.8.0.77 (i think there no point downgrade java previous versions (<=1.7) becouse main application using version) i'm sure have correctly configured environment variables ( java_home , jre_home , path , catalina_home ) i configured data base connection ( db.properties , context.xml ) in activiti-explorer.war , moved file tomcat/webapps i don't have errors activiti during tomcat start check if activiti explorer deployed tomcat in manager. http://{host}:{port}/manager/html more info in https://tomcat.apache.org/tomcat-7.0-doc/manager-howto.html

for example when use sqlitedatabase in android, not idea open/close lots of sqlitedatabase helpers. instead better create sort of singleton makes sure have 1 database open. say have class static methods doing lots of firebase operations require databasereference. example: static void checkifuserismatched(...) static void notifyuser(...) static void modifyuser(...) is ok call firebasedatabase.getinstance() inside every method? create new databasereference inside each method? or better pass databasereference calling activity? static void notifyuser(muserreference, hisuserid) vs static void notifyuser(myuserid, hisuserid) --> create reference inside method what im looking optimize network usage , performance. or not matter , firebase handle me? firebasedatabase , databasereference objects can considered relatively cheap references underlying resources. the firebase sdk manages such things behind scenes. first call firebasedata.getinstance() set work, s...

i trying access strava api , recieve error xmlhttprequest cannot load https://www.strava.com/api/v3/segments/626273/leaderboard?per_page=1&page=1&gender=f&access_token=xxxxx. no 'access-control-allow-origin' header present on requested resource. origin 'https://s3.amazonaws.com' therefore not allowed access. i can access link directly, not through request. below code based of off other solutions tried, didn't work. hosting in s3 bucket don't have server side trying solution in angularjs. app = angular.module('myapp', []); app.config(['$httpprovider', function($httpprovider){ $httpprovider.defaults.withcredentials = true; }]); app.controller('myctrl', function($scope, $http) { $http.get("https://www.strava.com/api/v3/segments/626273/leaderboard?per_page=1&page=1&gender=f&access_token=xxxxx").then(function(response) { $scope.mywelcome = response.data; }); });

i'm trying save development time of adding user creation logic in ios app, , considering scenario: user purchases app through app store. via app, give them url lets them create signon site (since have purchased app). how validate signup legit (besides url)? apple provide kind of id check user against? edit: option provide additional button says "sign up", in addition current "sign in" button. take little more time, though. edit 2: change make non-opinion based. what if take app's receipt , send directly server? nsstring *receiptpath = [[[nsbundle mainbundle] appstorereceipturl] path]; nsdata *receiptdata = [nsdata datawithcontentsoffile:receiptpath]; nsstring *encodedreceipt = [receiptdata base64encodedstringwithoptions:null]; // send encodedreceipt server you server can validate receipt, use (original) transactionid app unique key, , credit user.
