i building node.js application involves redirecting user input server-side command. of course, catastrophic security, desire run child command inside selinux sandbox . (i not want run entire application inside of sandbox because want end users each have own workspace on server.) for example, consider command cowsay . in order run sandboxed cowsay, need sandbox cowsay . other behind-the-scenes security differences, interface of sandbox cowsay should same of plain cowsay . however, node.js responds differently these 2 approaches. consider code: var spawn = require('child_process').spawn; var cmd = spawn("cowsay", ["hello"]); // line (no sandbox) var cmd = spawn("sandbox", ["cowsay", "hello"]); // line b (with sandbox) cmd.stdout.on("data", function(data){ console.log("stdout: "+data); }); cmd.stderr.on("data", function(data){ console.log("stderr: &qu

i passing list of images report. want render inside list object in report. i have used jasperreports lists before , i'm aware can reference each field of element in list using $f{} tag, how can reference element of list itself? basically use $f{this} , or $f{self} . there such thing? yes, can use alias _this . the quote jasperreports ultimate guide : special field mapping can used access current javabean object itself. thus, when field uses _this description or name, data source return current javabean object field value. useful when report needs extract current object data not correspond property follows javabeans standards (for instance, data returned method takes arguments), or when current object needs passed argument method called in 1 of report expressions. the sample of using _this the snippet of jrxml file: <subdataset name="dataset1"> <field name="city" class="java.lang.string"> <fieldd

this question has answer here: why data.table update names(dt) reference, if assign variable? 1 answer well one's bit strange... seems creating new column in data.table using := operator, assigned variable (created using colnames) changes silently. is expected behaviour? if not what's @ fault? # lets make simple data table require(data.table) dt <- data.table(fruit=c("apple","banana","cherry"),quantity=c(5,8,23)) dt fruit quantity 1: apple 5 2: banana 8 3: cherry 23 # , assign column names variable colsdt <- colnames(dt) str(colsdt) chr [1:2] "fruit" "quantity" # let's add column data table using := operator dt[,double_quantity:=quantity*2] dt fruit quantity double_quantity 1: apple 5 10 2: banana 8 16 3: cherry 23

while soap standard transport layer agnostic, microsoft in infinite wisdom decided helper classes shouldn't be, @ least not in obvious, documented way. so there third party library or other mechanism (i'm thinking soap aware xml serializer perhaps) accepts parameter soap message (as string or stream) , returns meaningful data structure (like dictionary or dynamic), or have write myself?

could give overview or summary of purpose of beans in spring framework context? i understand standard java bean (no arg constructor, getters/setters, serialized), spring bean purpose seems different. is way of implementing singleton design pattern (one instance, factory classes) in simple, reusable fashion? i've used spring annotations , feel need grasp in order understand spring. thanks! i understand standard java bean (no arg constructor, getters/setters, serialized), spring bean purpose seems different. you mean always serialized. why think purpose seems different? in end, write classes. lot of time these pojos, plain old java objects. implement interface or extend class, classes. beans classes. don't overcomplicate it. now spring might take beans (classes) , manage them via of number of policies (prototype, singleton) doesn't change bean is, speaks how spring manages bean.

i'm trying learn use node. far, good. but, being pretty new javassript , don't point of using callbacks when cleaner , more readable (at least me) syntax available. here's example code make point clearer: with callback: exports.create = function(req, res){ new todo({ content : req.body.content, updated_at : date.now() }).save(function(err, todo, count){ res.redirect('/'); }); }; without callback: exports.create = function(req, res){ newtodo = new todo({ content : req.body.content, updated_at : date.now() }); newtodo.save(); res.redirect('/'); }; both of these codes save new todo , redirect. my preference goes second one, find easier read, maybe there's difference don't get. there difference? the short answer is: avoid locking user interface while operation takes time finishing executing. in second example, if save function makes ajax call, have make synchronous ajax call.

i made researches; didn’t find similar question. if question duplicated please excuse me because didn’t find in researches. i have 2 schemas, schema1 , schema2, , both of them have same 6 tables. but not every table have same column in schema. exp: tab1 has 40 column exists in schema1 tab1 has 38 columns exists in schema 2. there 2 missing columns want add them. there data need insert. i can insert them manually take me time, isn’t there simple query? in researched found tools that. thanks the following show columns in schema1 don't exist in schema2. select table_name, column_name, data_type, data_length all_tab_columns owner = 'schema1' minus select table_name, column_name, data_type, data_length all_tab_columns owner = 'schema2' i edited above include alex's suggestions include data type , length in output.

i have list of guids need put array literal in vb. each of them corresponds entity i'd document in code. in c#, i'd this: var guids = new[] { guid.parse("70b11854-ac3e-4558-85d9-dc2451d7dce2"), // thing foo guid.parse("dec3cc2c-9d22-4d7f-8293-8e584795211c"), // thing bar }; i'd in vb: dim guids = { guid.parse("70b11854-ac3e-4558-85d9-dc2451d7dce2"), ' thing foo guid.parse("dec3cc2c-9d22-4d7f-8293-8e584795211c") ' thing bar } but comments in middle of (multi-line) statement not legal. there way achieve type of comment in vb? vb not support this. the best option split multiple statements. const guid1 = "70b11854-ac3e-4558-85d9-dc2451d7dce2" ' thing foo const guid2 = "dec3cc2c-9d22-4d7f-8293-8e584795211c" ' thing bar dim guids = { guid.parse(guid1), guid.parse(guid2) } this @ least provides comments inline without adding overhead.

i'd run integration tests against running server , retrieve server output check later. here cheap way local slave (otherwhise you'll need fileupload step) class stopserver(shellcommand): def _init_(self): shellcommand.__init__(self, command=['pkill', '-f', 'my-server-name'], workdir='build/python', description='stopping test server') def createsummary(self, log): buildername = self.getproperty("buildername") f = '/home/buildbot/slave/%s/build/python/nohup.out' % buildername output = open(f, "r").read() self.addcompletelog('server output', output) class startserver(shellcommand): def _init_(self): shellcommand.__init__(self, command=['./start-test-server.sh'], workdir='build/python', haltonfailure=true,

i have make database system purely on sql server. it's diagnostic lab. should contain @ least 40,000 distinct patient records. have table named "patient" contains auto-generated id, name, dob, age , phone number. our teacher provided dummy stored procedure contained 2 temporary tables has 200 names each , in end makes cartesian product supposed give 40,000 distinct rows. have used same dummy stored procedure , modified according our table. rows inserted 1260 every time. each time run query not give more 1260 records. have added part of temporary name tables , stored procedure. declare @tfirstnames table( firstname varchar(50) not null ) declare @tlastnames table ( lastname varchar(50) not null ) declare @tnames table ( id int identity not null, name varchar(50) not null) insert @tfirstnames (firstname) select 'julianne' union select 'sharyl' union select 'yoshie' union select 'germaine' union select 'ja' union sel

i trying jquery struggling bit around. what i'm trying go through array 1 click @ time each time click on "next" button new item presented. let's take @ following code: $(document).ready(function(){ var stuff =["house","garden","sea","cat"]; (var i=0; i<stuff.length;i++) { console.log(stuff[i]); } }); now how thinking creating while loop $("#next").on('click', function(){i++;}); but somehow doesn't work. able explain me how in relatively simple way? when run through loop for statement, , not in response event. instead, want step through array each click. so, need define counter outside click function , increment (or reset, if you've reached end of array) each click. here sample code: $(function () { // shortcut document ready var stuff = ['house', 'garden', 'sea', 'cat'], counter = 0; console

nsstring *string = [nsnumber numberwithint:2]; int var = [string intvalue]; var 2. so, why? understand, it's smth dynamic typing, what's under hood? there no casting going on in code example: [string intvalue] regular objective c method provided nsnumber retrieve value stored inside integer. fact assigned object nsstring pointer not change anything: object inside remains nsnumber . not crash because objective c dynamically typed language. lets assign objects of wrong types, if try calling methods of nsstring on string object, going crash: nsstring *string = [nsnumber numberwithint:2]; int var = [string intvalue]; // ok bool istwo = [string isequaltostring:@"2"]; // crash

if have buttonclick event sets cursor := crhourglass, application.processmessages, use topendialog choose file, , cpu-intensive, cursor behaves differently depending on whether on existing control when open dialog closes. if cursor on control cursor remains hourglass; if it's outside application , moved area while intensive process still taking place, cursor remains arrow. 1 cannot click or it's confusing user arrow not able it. stepping through debugger shows cursor -11 everywhere should be. using screen.cursor instead of cursor has same effect. is there solution? procedure tmyform.loadbuttonclick(sender: tobject); begin cursor := crhourglass; application.processmessages; if opendialog.execute begin // intensive // cursor = crhourglass here displayed different end; cursor := crdefault; end; first, make sure set cursor while cpu-intensive operation active. don't change cursor while choosing file — never see other programs that, after all

i've tried: console.log(element('.users').html()); but thing log: { name: 'element \'.users\' html', fulfilled: false } i assume using angular scenario runner. the element().html() dsl returns future (see wikipedia ). logging future contain element, @ point when calling console.log , future not resolved yet - there no value in there. try this: element('.users').query(function(elm, done) { console.log(elm.html()); done(); }); the whole scenario runner works queue. test code executed (synchronously) , each command (eg. element().html in case) adds action queue. then, these actions executed asynchronously - once first action finishes (by calling done() ), second action executed, etc... therefore individual actions can asynchronous, test code synchronous, more readable.
