i have code inserts row db, using custom contentprovider: uri contenturi = uri.withappendedpath(dataprovider.content_uri, usertable.table_name); uri resulturi = getcontext().getcontentresolver().insert(contenturi, contentvalues); boolean success = (long.parselong(resulturi.getlastpathsegment()) != -1); the insert() method defined in contentprovider follows: public class dataprovider extends contentprovider { // ... @override public uri insert(uri uri, contentvalues initialvalues) { string table = gettablename(uri); sqlitedatabase database = dbhelper.getwritabledatabase(); long value = database.insert(table, null, initialvalues); return uri.withappendedpath(content_uri, string.valueof(value)); } } i've noticed that, sometimes, insertion fails returning row id equals -1 (as can see in third line of first code, success should become false). problem can't understand reason because logcat doesn't print exception related

assuming have directory structure: /tmp/mysockets/appname/ what security drawbacks doing chmod 777 on /tmp/mysockets/? user delete or mess reference appname/ directory? want allow other users add own directories /tmp/mysockets/ don't want allow them rename or delete files/subdirectories inside (owned user). i think looking sticky bit, thats want. permissions 777 grant read/write permissions therefore files can removed/renamed a sticky bit permission bit set on directory allows owner of file within directory or root user delete or rename file. no other user has needed privileges delete file created other user. to set sticky bit use following chmod o+t /tmp/mysockets/ or e.g. chmod 1757 /tmp/mysockets/

here hierarchy: a - b - c - d (tabs) | | | | | | | | ----------------> addeventviewcontroller (can called tabs) | | |----> suggestfeedcontroller (can accessed b only) let's imagine i'm in d tab, , call addeventviewcontroller. after this, want redirect user "suggestfeedcontroller", want keep hierarchy, means pressing button should redirect b , not addeventviewcontroller nor d. what have tried following: uitabbarcontroller *tabbarcontroller = ((uitabbarcontroller *)appdelegate.window.rootviewcontroller); [tabbarcontroller setselectedindex:1]; // selecting b tab uistoryboard* storyboard= appdelegate.window.rootviewcontroller.storyboard; uicategoryfeedcontroller *cfvc = [storyboard instantiateviewcontrollerwithidentifier:@"uicategoryfeedcontroller"]; // instantiating b view controller suggestfeed *suggestfeed = [storyboard instantiateviewcontrollerwithidentifier:@"suggestfeed"]; nsarray

i developing web application using sails.js back-end. app used different schools , first approach deploy each school instance of application. example: school1.application.com having instance of sails app on school.application.com:8080 school2.application.com having instance of sails app on school.application.com:8081 each instance have bitbucket repository (or branch) , source updated using git. for maintenance purpose, thinking of using dashboard connected git repository , manage push there. on other hand, more manageable have 1 instance school how used separate database each 1 ? using 1 db not risky when having 20 schools ? using second approach, if application down, schools affected opposed first one. i hope clear in explanations. thank insights. where sails app hosted? you? i.e. nodejitsu, amazon, etc. or app deploy on school server? approach: if you'll host app, can make 1 app , deploy once. add schools models , create relationship between users

i want capture output of top variable instead of file. and tried below top -n 1 -b | head > top_op echo "inside: $top_op" $top_op | grep cpu > cpu echo "$cpu" but output just inside: if want store output variables, use command substitution: top_op=$(top -n 1 -b | head) echo "inside: $top_op" cpu=$(echo "$top_op" | grep cpu) echo "$cpu" using backquotes $() more recommended recursive without quoting. top_op=`top -n 1 -b | head`

i have listview rows big device screen , want show row per row while sliding, don't want show parts of rows when doing so, there way of doing it. listviews not made kind of use case. viewpagers are, scroll horizontally. it's possible make scroll vertically (see android: vertical viewpager ), should you're looking for. the problem adjusting size of each listview item fill screen match_parent doesn't work. need calculate exact size need (screen height minus action bar , other views not part of listview). it's possible, not worth trouble.
