i want write simple batch file kill process contains text in window title. right have: taskkill /fi "windowtitle eq xxxx*" /im cmd.exe and works, except want use wildcard both @ beginning , end of title. like: taskkill /fi "windowtitle eq \*x*" /im cmd.exe but tried , not work. there i'm missing or not possible? no, wildcards not allowed @ start of filter. for /f "tokens=2 delims=," %%a in (' tasklist /fi "imagename eq cmd.exe" /v /fo:csv /nh ^| findstr /r /c:".*x[^,]*$" ') taskkill /pid %%a this retrieve list of tasks, in csv , verbose format (that include window title last field in output). the list filtered findstr regular expression search indicated text (the x ) in last field. if line matches filter, for tokenize it, retrieving second field (the pid) used in taskkill end process.

from docs , need use reactive data container around component retrieve logged in user (if 1 exists), how data container? import { meteor } 'meteor/meteor'; import react, { component } 'react'; import { createcontainer } 'meteor/react-meteor-data'; export default foocontainer = createcontainer(() => { return { user: meteor.user() }; }, class foocomponent extends component { render() { return (<div>{ /* this.data.user ??? */ }</div>); } }); how data returned container function inside render method? i see returned user key in container, therefore data accessible via this.props.user prop in component. just make sure add container: export default foocontainer = createcontainer(() => { const subscription = meteor.subscribe("userdata"); subscription.ready() ? session.set("dataready", true) : session.set("dataready", false); return { user: meteor.user() }; } and in rende

i'm passing in name of checkbox option in jquery d3 in order render new tab li element same name. but tried passing in option name eg, "option1" creates new tab each letter in string using .data(val) option. so in example below val = "option1" , create tab this: d3.select("ul#charttabs") .selectall("li") .data(val) .enter() .append('li') .insert("a", ":first-child") .attr("data-toggle", "tab") .attr("id", function(val, i){ var result = val + i; return result; }) .text(function(d){ return d; }) question: how can create 1 tab per call d3.append? this current output when passing in val "option1" . not expected creates new tab each letter. instead of single button value option1. d3 coercing string array, use .data([val]) ,

i trying unpack hex string double in python. when try unpack following: unpack('d', "4081637ef7d0424a"); i following error: struct.error: unpack requires string argument of length 8 this doesn't make sense me because double 8 bytes long, and 2 character = 1 hex value = 1 byte so in essence, double of 8 bytes long 16 character hex string. any pointers of unpacking hex double super appreciated. you need convert hex digits binary string first: struct.unpack('d', "4081637ef7d0424a".decode("hex")) or struct.unpack('d', binascii.unhexlify("4081637ef7d0424a")) the latter version works in both python 2 , 3, former in python 2

i want use collective.autopublish set outdated plone pages private. goal set plone pages private after expiration date automatically. (similar problem described here ) i installed collective.autopublish , can configure in web interface. should use collective.timedevents extension triggered. added , tried install using readme file. told me add zope clock-server triggering events, did according code snippet on page. [instance] ... zope-conf-additional = <clock-server> method /mysite/@@tick period 90 user clockserver-user password password host localhost </clock-server> i changed mysite plone url. clock-server seems work, got http calls /mysite/@@tick page every 90 seconds, resulting in 404 errors, nothing triggered collective.timedevents. did miss or wrong documentation? should work? btw: registered handler collective.autopublish itickevent. i'm unable answer question directly can provide more simpler solution problem. as see,

i'm using comparisons like: if type( self.__dict__[ key ] ) str \ or type( self.__dict__[ key ] ) set \ or type( self.__dict__[ key ] ) dict \ or type( self.__dict__[ key ] ) list \ or type( self.__dict__[ key ] ) tuple \ or type( self.__dict__[ key ] ) int \ or type( self.__dict__[ key ] ) float: i've once discovered, i've missed bool type: or type( self.__dict__[ key ] ) bool \ , okay - wondered other types missed? docs.python.org - there no table types... i've started googling: diveintopython3 : python has many native datatypes. here important ones: booleans either true or false. numbers can integers (1 , 2), floats (1.1 , 1.2), fractions (1/2 , 2/3), or complex numbers. strings sequences of unicode characters, e.g. html document. bytes , byte arrays, e.g. jpeg image file. lists ordered sequences of values. tuples ordered, immutable sequences of values. sets unordered bags of values. dictionaries unordered

as per liquibase documentation: each changeset tag uniquely identified combination of “id” tag, “author” tag, , changelog file classpath name. this seems poor design choice. identity of changeset shouldn't linked location. if changelog run via automatic application deployment changeset come classpath location within jar file. if want run same changesets commandline manually, location might current directory. in case instead of recognizing changeset same based on id liquibase try apply twice. is there way change behavior , have identify changesets basis specified id? i suggest using logicalfilepath attribute of databasechangelog tag. this gives more freedom change directory structure of project. prevents file name being stored absolute path (which might happen in circumstances).

i wondering how create separated indexes different logs fetched logstash (which later passed onto elasticsearch ), in kibana , can define 2 indexes them , discover them. in case, have few client servers (each of installed filebeat ) , centralized log server ( elk ). each client server has different kinds of logs, e.g. redis.log , python logs, mongodb logs, sort them different indexes , stored in elasticsearch . each client server serves different purposes, e.g. databases, uis, applications. hence give them different index names (by changing output index in filebeat.yml ?). in filebeat configuration can use document_type identify different logs have. inside of logstash can set value of type field control destination index. however before separate logs different indices should consider leaving them in single index , using either type or custom field distinguish between log types. see index vs type . example filebeat prospector config: filebeat: prospectors

in gwt 2.7 there known bug *.nocache.js files, not getting actual timestamp while compiling timestamp of module file (see this ). for gwt-maven-plugin there workaround commited ( see compilemojo.java ). for projects not built maven wanted ask, if knows "maven-free" , automated solution workaround?! what i'm doing right know touching file on linux server find /my/path/ -name '*.nocache.js' -exec touch {} \; && which working fine right now. can use copy /b filename.ext +,, on windows, wanted know if knows automated workaround compilation issue in gwt 2.7 (with eclipse) you can install "touch" command on windows , keep using current script. you can find number of implementations of touch windows, here open source one: https://sourceforge.net/projects/touchforwindows/

i've been attempting implement new rxjs observable in angular 2 component using typescript. have created service, myservice returns observable in 1 of methods, e.g., export class myservice { getmyobs(){ return new observable(observer => { observer.next(42); }); } } then in angular 2 component subscribe observable in oninit, e.g., export class mycomponent implements oninit { obs: any; constructor(private myservice: myservice){}; ngoninit { this.obs = myservice.getmyobs().subscribe(data => { // stuff here... }); } } the rxjs documentation talks unsubscribing observable such observable knows no longer emit messages observer. therefore, figured should unsubscribing observable when component gets destroyed, like export class mycomponent implements oninit, ondestroy { obs: any; constructor(private myservice: myservice){}; ngoninit { this.obs = myservice.getmyobs().s
