so i've been studying abstract classes , dynamic binding , decided test out couple of examples. i have following 3 classes: abstractdemo (main), myabstract , mysubabstract. main method calling methods both classes using dynamic or static binding. all of following calls work except last 1 try use dynamic binding , call 1 of methods defined in subclass (sub1()). assume despite being declared reference of superclass object still able find method declared within object's class. can please explain why? public abstract class myabstract { public abstract void abs1(); public abstract void abs2(); public void nonabs1() { system.out.println("myabstract nonabs1"); } public void nonabs2() { system.out.println("myabstract nonabs2"); } } public class mysubabstract extends myabstract { public void abs1() { system.out.println("mysubabstract abs1()"); } public void abs2() { system.out.println("mysubabstract abs2

i'm new site encryption , looking expend knowledge certificates while surfing online , i've stumbled on this site when looking on cert chain looks legit : but ... when capture ssl handshake , 1 of certificates missing : my question(s) : 1) how come browser sees cert chain depth 3 details while wireshark doesn't ? 2) how legit the root issuer not part of chain ?? i've tested using chrome , explorer what missing here ? how come browser sees cert chain depth 3 details while wireshark doesn't ? the browser shows trust path locally stored root ca, including root ca. wireshark showed certificates sent server. while leaf certificate same intermediate certificates (and root) might differ depending on certifaces trusted browser already. how legit the root issuer not part of chain ?? the idea of certificate validation never trust peer, because peer might lying you. instead have local ca certificates (trusted root) , build trust c

i need use composite key or unique index comprised of bigint data type , datetime data type. however, i've noticed seconds element of datetime has been rounded nearest minute , causes duplicate key violation when trying import dataset. the dataset transactional data, our id (stored in bigint field) repeated, hence need inclusion of datetime field in unique key. to give example: following 2 rows cause 'duplicate key row' error: id field (bigint) | actiondate (datetime) --------------------- |-------------------------- 1050000284002 | 2016-01-08 15:51:24.000 1050000284002 | 2016-01-08 15:50:35.000 the values different (and stored correctly in database) error shows: the duplicate key value (1050000284002, jan 8 2016 3:51pm). (it's worth adding created composite key , have since replaced unique index; error outlined above generated index in place.) my questions are: is datetime field being rounded because i'm using int

i working on open source python project depends on lot of non-python packages (perl, r, ...). consequently, use conda install dependencies, can't installed pip. you can run $ conda install --channel bioconda <awesome_package> install stable build of package. want install in development mode. purely python project, i'd this: pull source code github $ cd path/to/awesome_package && pip install -e . run tests modify code run tests etc in step 2 above, pip command installs need work. uses setup.py script job, , requirements.txt requirements_dev.txt install dependencies. and, don't need rebuild/reinstall when change in source code. how do same conda instead of pip ? how provide list of requirements (python , non-python) conda ? the relevant thing found this: http://conda.pydata.org/docs/building/bpp.html however, approach i'd need rebuild , reinstall package locally time want run tests, i'd avoid. i going change python source

good afternoon. i'm maintaining application needs parse directories. application uses file.isdirectory() detect whether given path directory or file, recursively fetches files , sub-directories contained. this works, unless directory name contains spaces, path c:\foo\bar detects both foo , bar directories, desired behaviour; path such c:\f oo\bar not: file.isdirectory() returns false (as file.isfile() ) on such path. on other hand, file.isabsolute() returns true - it's absolute path, neither file nor directory, according file library. is there workaround? alternatives detect whether given path directory? or doomed running application on directories no spaces in them? thank attention. edit: file created rather tortuous process involving string being converted file string , file on 5-6 method calls (not code). anyway, i've located root of issue, think. i'll fix it. should delete question? don't see being useful future users. i tried

this follow-up of this question. there learned how remove characters after last number in string; can turn w = 'w123 o456 t789-- --' into w123 o456 t789 now might have strings this: w = 'w123 o456 (t789)' in case, re.sub(r'\d+$', '', w) would give me w123 o456 (t789 so have 2 closely related questions: 1) how can modify command re.sub(r'\d+$', '', w) in way characters kept (e.g. parenthesis)? 2) how can modify command re.sub(r'\d+$', '', w) characters removed (e.g. dashes , white spaces)? edit @martin bonner's answer gets close e.g. w='w123 -o456 t789--) --' the command re.sub('[- ]+$', '', w) gives me w123 -o456 t789--) should rid of remaining dashes. you may use re.sub in callback replacement pattern. re.sub(r'\d+$', lambda m: re.sub(r'[^()]+','',m.group(0)), s) here, match symbols other digits @ end of string,

i'm migrating docker server centos coreos. when tried configure docker demon send log messages logstash using gelf (graylog extended logging format) got following error docker: error response daemon: cannot start container c2522f318221b53fb360dca08c806f20b5b04b55529e89d79658d328c196c4ca: failed initialize logging driver: failed logging factory: logger: no log driver named 'gelf' registered q: docker on coreos compiled without gelf support? i continue using gelf because docker adds fields image_name log-messages default. q: there log driver supports that? edit: the server: kernel version: 4.1.7-coreos-r1 operating system: coreos 766.5.0 and docker client version: 1.7.1 client api version: 1.19 server version: 1.7.1 server api version: 1.19 the gelf logging driver added in docker 1.8.0 . either upgrade docker (and coreos) or you're out of luck.

i working on retail app. use mobile app allowing guests access free wi-fi in stores. the ideal outcomes if user has mobile app, user automatically logged wi-fi without manual intervention. if user not have mobile app, user sees splash page , given option download mobile app. once mobile app download selected, given access network 3 specific questions: is there way in app can access available wifi ssid's seen iphone / andriod? , can app join chosen ssid? how done is there way in app fills out splash page information access? how done is there recommended best practices enabling this- know more of opinion, looking examples learn from. thanks, nb: have tried splash pages / captive portals don't want additional step causes friction in adoption

this program suppose convert decimal binary somehow screw up can 1 point out error me? thanks lot #include<conio.h> #include<stdio.h> int main(){ int a; int b[20]; int q = 0; printf("decimal : ");scanf("%d",&a); while(a>0)) { b[q]=a%2; a=a/2; q++; }while(a>0); printf("binary : "); (int = q-1; i>=0;i--){ printf("%d",b[q]); } } corrected code is: #include<conio.h> #include<stdio.h> int main(){ int a; int b[20]; int q = 0; printf("decimal : ");scanf("%d",&a); while(a>0) { b[q]=a%2; a=a/2; q++; } printf("binary : "); (int = q-1; i>=0;i--){ printf("%d",b[i]); } } you printing b[q] instead of b[i]

i creating dashboard direct query. using line graph visulations plotting transaction volumes , splitting them: credit or debit. on same graph overlay current balance. please see attached image. combine these 2 graphs dont know how to. advice welcomed! enter image description here i change visualization line , stacked column chart . can use account balance column series . the line values little trickier. need 2 new calculated measures, like: credit = calculate ( sum ( 'my table'[volume] ) , 'my table'[txnmethod] = "credit" ) ditto debit. note guessing aggregation [volume]. add 2 new measures line values . buried in format section under y-axis show secondary switch, turn on separate y-axis lines.
