i on low-speed network. how can push large git commits kind of resume capability? like, can upload chunks of patch files combine them on git server, push them master? usually i'd recommend git such purposes, since compresses , transmits quite efficiently. anywho -- have branch you'd cherry-pick 1 commit @ time , push them individually, say. btw, smaller commits way go! ;-) also, create patches, of course, , upload them somehow else (scp, ...) might resumable way, , apply them on git server. doubt, more efficient, using git.

i newbie in node.js, , trying learn how works. know default node.js function calls asynchronous. need ldap authentication in application need wait server response check whether user credentials right or wrong.the ldap part working fine not sure on how return data function call in synchronous way. below part of code. router.js var express = require('express'); var router = express.router(); var tools = require('./authenticateuser'); router.post('/authenticateuser', function(req, res) { // in below line calling method // should return userdn (a string) tools.searchuser(req.body.user, req.body.passwd); res.render('home.jade'); }); authenticateuser.js module.exports = { searchuser : function (username, password) { admindn = *************; adminpassword = '*********'; basedn = '***'; var ldap = require('ldapjs'); process.env.node_tls_reject_unauthorized = "0";

my program should play video when user presses 'play' button. while this, first time press 'play' button nothing happen. i have traced bug following code, sets mediaelement 'videoplayer': public void playvideo_tapped(object sender, tappedroutedeventargs e) { setupvideo(); videoplayer.play(); } public async void setupvideo() { if(vm == null) return; storagefile videofile = vm.videofile; if (videofile == null || !videofile.contenttype.equals("video/mp4")) return; using (irandomaccessstream filestream = await videofile.openasync(fileaccessmode.read)) { videoplayer.setsource(filestream, videofile.contenttype); } } the culprit seems 'setsource()' method @ end. variable changes first click of 'play' next variable 'videoplayer.playtosource', changed null real value. (as side note, variable 'videoplayer.currentstate' changes 'closed' 'opening' resets 'closed' bef

i working mathematical model functions contained within matrices simulate dynamics of biological populations. requires calling function update matrix, carrying out matrix multiplication project dynamics of system next time step. i'm wondering if possible embed function directly within matrix , skip explicitly updating matrix elements. the model looks this: state of system in matrix x1, eg x <- c(0,10) the system changes according matrix a a <- matrix(data = c(0, na,0.75,0.75),nrow =2,byrow = t) [,1] [,2] [1,] 0.00 na [2,] 0.75 0.75 where element na function of element 2 in x1, this f.a.12 <- function(x.2){1 + (1 - x.2/1000)} so system simulated this: update marix based on status of x a[1,2] <- f.a.12(x[2]) iterate model updated matrix: a%*%x [,1] [1,] 19.9 [2,] 7.5 this gets iterated 1000 times, updating before each multiplication the real model uses larger matrices containing multiple functions. there r package allows me embe

i'm creating budget in excel , therefore have categories , subcategories. subcategories intended 1 cell compared respective parent category. subcategories of course can have subcategories on own. in column next "category tree" want print "category path". let's have following tree of categories: i want "category path" printed next this: i thought compose category path category path of parent category (if any) , category name on current row. subcategories can have subcategories on own, don't know in column category name on current row stored. category name on current row i'm using following formula (found on this site (german) ): {=index(a7:f7;match(true;a7:f7<>"";0))} i know there's no category more 5 levels deep, therefore can savely "hard code" e.g. range a7:f7 row 7 , receive "side job" result of above formula. now comes tricky part (at least me) , reason i'm asking question: n
