i've got container run as docker run -it --rm --name <container_name> <image>:<tag> normally, fall container terminal can exit exit command. now, have dockerfile ends entrypoint runs simple bash script: #!/usr/bin/env bash # add new user groupadd -r $group --gid $groupid useradd -r $user --uid $userid --gid $groupid # launch application new user su - -c "python <path_to_script>/myscript.py" $user now, once script ends, expected exit container in entrypoint bash script ran again , again (say 10 times). why container have behavior ? su manpage says: -, -l, --login provide environment similar user expect had user logged in directly it spawns shell exit comeback parent container shell. so changing su - -c "python <path_to_script>/myscript.py" $user to su "$user" -c "python <path_to_script>/myscript.py" might solution sidenote : - -c

how can achieve single logout openid connect identity server 5.1.0 see there documentation ( https://docs.wso2.com/display/is520/configuring+openid+connect+single+logout ) version 5.2.0 can't open link. for logout in both applications right now, i'm following https://stackoverflow.com/a/29965502/525162 want logout second application after first 1 logged off. do need saml sso? possible openid connect 5.2.0 forward? thanks, diogo the documentation work in progress. that's why can't access right now. 5.2.0 have openid connect session management 1.0 spec[1] implemented allow use case have mentioned. ie. if there 2 rp applications relying on wso2 identity server, when end user logs-out of 1 of applications, he/she can automatically logged out of other 1 well.

i trying import data mysql hive using querydatabasetable , puthiveql processors, error occurs. i have questions: what output format of puthiveql ? should output table created beforehand or processor that? where can find template mysql hive process? here information questions: the flow files input puthiveql output after have been sent hive (or if send fails), output format (and contents) identical input format/contents. the output table should created beforehand, send puthiveql "create table if not exists" statement first , create table you. i'm not aware of existing template, basic approach following: querydatabasetable -> convertavrotojson -> splitjson -> evaluatejsonpath -> updateattribute (optional) -> replacetext -> puthiveql querydatabasetable incremental fetches of mysql table. convertavrotojson records format can manipulate (there aren't many processors handle avro) splitjson create flow file each of records

i have 2 columns of differently formatted date strings need make same format, the first in form: vt_dev_date = "6/20/2016 7:45" the second in form vt_other = "2016-06-14 20:21:29.0" if them both in same form down minute great. have tried strptime(vt_dev_date,format = "%y-%m-%d %h:%m") strptime(vt_other,"%y-%m-%d %h:%m") and second one, works , "2016-06-14 20:21:00 edt" but first string, seems because month , hour not padded zeros, none of formating tricks work, becuase if try test_string <- "06/20/2016 07:45" strptime(test_string,format = "%m/%d/%y %h:%m") [1] "2016-06-20 07:45:00 edt" it works, dont think going through every row in column , padding each date great option. appreciated. thanks, josh how using lubridate , follows : library(lubridate) x <- c("6/20/2016 7:45","2016-06-14 20:21:29.0") > x [1] "6/20/2016 7:45"

is possible develop algorithm estimate time complexity of algorithm? mean, input algorithm , output time complexity of (big-oh, big-omega, , on). not find on web. thank you let me extend @interjay's comment little bit. the halting problem asking if possible design turing machine (you may think program in computer) such given turing machine (again, think program) can decide whether or not input turing machine terminate eventually. one can prove impossible design such turing machine. let consider question, if able design algorithm want, able answer whether given turing machine terminate or not. unfortunately impossible. above argument called "reduction" 1 of popular way show given problem unsolvable.

i spending long time trying accomplish without ideas. have data model, need put collection view. main problem collection views not elastic. the data model can in different structure similar this, , not symmetrical. can in other order but go down . difference side in index goes. i have tried : creating sections in each section gets 2 cells, when creating layout had problem single cell in section must on right side, , next on left. delegate's order opposite, , complications of moving cells around. inserting cell specific index, can set section 2 indexes , insert cell index 1 directly , not 0 . (this impossible because max index should maximum data.count ) should build myself? these things possible collection view @ all?

i have little problem new custom control. question want resizes 32px-steps create grid, i'm looking event of post-resizing, or similar adjust control's size. has ideas? just enforce size requirements: class mygrid : control { private const int pitch = 32; protected override void onclientsizechanged(eventargs e) { var w = pitch * ((this.clientsize.width + pitch/2) / pitch); var h = pitch * ((this.clientsize.height + pitch/2) / pitch); if (w != this.clientsize.width || h != this.clientsize.height) this.clientsize = new size(w, h); else base.onclientsizechanged(e); } } it not fantastic design-time experience serviceable , simple since doesn't require custom designer. do careful this, hard-coding sizes in pixels not idea these days 4k monitors available , costing less $500. 32 px grid cell going fleck of dust on such screen.

when should use drools stateless session , benefits of using instead of stateful session? in comment here it's said stateless sessions wraps stateful one, means when destory statfeul session after firing rules behave stateful 1 ? perhaps better both (stateful) kiesession , statelesskiesessions provide apis (interfaces) classes based on class abstractruntime. a statelesskiesession provides interface executing set of commands via single execute method call, commands being represented set of objects. useful if want send commands remote session (but not if run session within application). also, such session not react changes done within working memory, usefulness limited, although might perform first , round more efficient stateful session. an execute call implies dispose call, final goodbye session object: release resources garbage collection. to summarize (what described in full in drools documentation) for simple rule evaluations, via remote communication

what determines when garbage collector collects? happen after time or after amount of memory have been used up? or there other factors? it runs when determines time run. common strategy in generational garbage collectors run collector when allocation of generation-0 memory fails. is, every time allocate small block of memory (big blocks typically placed directly "older" generations), system checks whether there's enough free space in gen-0 heap, , if there isn't, runs gc free space allocation succeed. old data moved gen-1 heap, , when space runs out there, gc runs collection on that, upgrading data has been there longest gen-2 heap, , on. gc doesn't "run". might run on gen-0 heap (and collections that), or might check every generation if has free lot of memory (which necessary rarely). but far only strategy. concurrent gc runs in background, cleaning while program running. gc's might run part of every memory allocation. incremental co
