i've tried search similar problem on here suprisingly couldn't find 1 posted already. i use expressjs v4 framework , i'm constructing routes this: 'use strict'; let express = require('express'); let router = express.router(); let users = require('./modules/users'); router.post('/',users.add); router.put('/edit/:id',users.edit); as can see above, i'm requiring let users = require('./modules/users') now users module looks (let's say) this: 'use strict'; let usersdbmodule = require('...'); let users = { 'add': (req, res, next) => { let callback = (err, record) => { //...do users.function1(record) } usersdbmodule.save(req, callback); }, 'function1': (record) => { users.function2() }, 'function2': () => { //...do next() function } } you can notice, router first

for small project, have following workflow: compile code , generate ./data , ./images run code, write many files ./data generate images data files, place them in ./images generate video images i have written makefile, can run code, , compile before, if necessary. don't know how implement dependencies of steps 3 , 4, , make targets manually. so, there way check if e.g. newest file in ./data newer newest file in ./images ? it's not necessary on file-by-file basis, , total number of data / image files not known. typically date of directory date last file added/modified, use timestamp on directory dependencies. images : data // generate images alternatively, if there mapping between files in 2 directories, like: images/%.img: data/%.dat // generate image... which prevent reprocessing data that's been handled.

the error occurs when try input large data. after reading lot of resources found causes of error follows- 1. touching memory location not allowed to. 2. using free() on memory have not reserved or double free() pointer. 3. initializing invalid index (such creating arrays negative index) found 1 cause may have caused error in code- link - https://discuss.codechef.com/questions/59703/prime-number-generation-sigabrt-problem-c which says- "may limit on n quite large! can atmost make array of 10^8 size online judges. in heap memory ie. outside main function. making array of size of 10^7 in main function can lead runtime errors. try not use more of order 10^8 elements array.. :) in question attempting upper limit 10^9 can make array of size. thats why sigabrt error means exceeded memory limit." then modified declaration , input part this- int main(void) { int test_cases; scanf("%i",&test_cases); (int i=0; i<test_cases; i++) {

i'm using scichart v3.1 , have requirement display 2 charts on same window (in different tabs), both displaying same data. i'm plotting data "real time" (adding new point every second), i'm finding new values don't appear on charts added bound series. i've found can charts refresh recreating visiblerange bound charts' y axis, isn't ideal. things work fine if there 1 chart on window, issue seems point using 2 charts. thoughts? appreciate i'm on older version curious if known issue, , whether there workaround. in scichart v3, seriessource api binds observablecollection of ichartseriesviewmodel . each ichartseriesviewmodel contains both dataseries , baserenderableseries (which framework element). hence, chart has wpf frameworkelements on 2 charts (two visual parents) - big no-no wpf terms. this known issue in scichart v3 , , result scichart team re-wrote api in version 4 of scichart. the new mvvm api: seriesbinding , separates

i have listbox defined as: <asp:listbox id="lst_agenda" onchange="drawchart()" onselectedindexchanged="lst_agenda_selectedindexchanged" selectionmode="multiple" cssclass="txt12 mylistbox" autopostback="true" datatextfield="name" runat="server" width="100%" height="100%" /> after select items in this, lst_agenda_selectedindexchanged method of codebehind called calls other listboxes populated in cascading way. there function in javascript named drawchart generates chart based on values selected in these listboxes. hence want codebehind function should called before javascript function call on listbox changed event. happening opposite, javascript function drawchart gets called first without filling values in listboxes. i tried calling javascript function codebehind method directly using: scriptmanager.registerclientscriptblock(this, this.gettype(), "myscript"

in spring boot, there way prevent auto configuration of modules? looking @disableautoconfiguration instead of excluding specific configurations class names. auto-configuration enabled @enableautoconfiguration annotation. if don't want use auto-configuration, omit annotation. note @springbootapplication annotated @enableautoconfiguration you'll have avoid using too. typically, leave main application class annotated @componentscan , @configuration .

i've been working on python program syntax of python still relatively new me. example, if have 2 python files contents below, what's proper way thread function? main.py - file being executed #!/usr/bin/env python #threading array threads = [] import threading import anotherfile af afcheck = af.init() #return true or false if afcheck == true: threads.append(threading.thread(target=af.listener)) try: thread in threads: thread.start() except (keyboardinterrupt, systemexit): print("closing shop"); thread in threads: thread.cancel() sys.exit() i going write dummy code anotherfile.py, seems pretty inconsequential. i've been able test point i've seen isn't executing listener , i'm not sure proper way call it. maybe need thread listener inside of anotherfile.py, thought simplicities sake, nice have them in 1 place since have multiple imports.

i have situation 1 xterm runs xterm runs process. set kind of watchdog , kill windows in case of stuck process. i'm using ruby this. when first xterm opened it's pid, , later when sigterm sent it, first xterm window dies, not second. it can reproduced in irb: irb(main):002:0> cmd = "xterm -e xterm -e sleep 1000" => "xterm -e xterm -e sleep 1000" irb(main):003:0> pid = process.spawn(cmd) => 669 irb(main):004:0> process.kill(15, 669) => 1 this leaves second xterm window open. how can process chain killed? thanks using either ps xf or pstree , can dynamically see running processes hierarchy. i've used strace track behaviour of programs. turned checking contents of /proc/$pid/stat , /proc/$pid/status , give them information of process's parent is. probably, have processes parent pid equal pid got (or process's ppid).
