can tell me what's wrong java code? array : static string [][] data = new string[6][2]; in case, data[0][1]="abcd" , data[1][1]="efgh" , remaining data[2-5][1] should null . trying print out non- null ones. @ (j=2,k=3) , code doesn't executed after that. eg, "i here3" doesn't printed. int k=1; system.out.println("data[2][0]="+data[2][0]); for(int j=0; j<data.length; j++,k++) { system.out.println("j="+j+" k="+k); if (!(data[j][0].equals("null"))) { system.out.println("i here2"); sbissues = sbissues.append("\n"); sbissues = sbissues.append(k); sbissues = sbissues.append(". "); sbissues = sbissues.append(data[j][1]); } system.out.println("sbissues="+sbissues.tostring()); system.out.println("i here1"); } system.out.println("i here3"); the output looks like: data[2]

what ob means in following code - same item? foreach (var item in allitems) { if (excludeitems.exists(ob => ob.equals(item))) { console.writeline("item {0} excluded",item); } } ob parameter lambda expression . if you're familiar anonymous methods, it's like: foreach (var item in allitems) { if (excludeitems.exists(delegate (string ob) { return ob.equals(item); }) { console.writeline("item {0} excluded",item); } } that's assuming type of ob should string - may not be. depend of excludeitems , due generic type inference. lambda expressions can more explicit, could written as: if (excludeitems.exists((string ob) => { return ob.equals(item); }) or if (excludeitems.exists((string ob) => ob.equals(item)) basically there several little shortcuts in lambda expressions common case of single parameter type can inferred, , return value single expression. now in particular case, dele

i trying use function histogram plot density of data. sample format of data follows: library(lattice) index<-c(1,1,1,2,2,2,2) freq<-c(3,4,6,3,6,2,2) d<-data.frame(index,freq) histogram(~d$freq|d$index) i want have index number printed strip text each histogram (i.e. in example, 1 , 2 on top of histograms respectively instead of printed d$index ), don't know of easy way (i know have use strip.custom() possibly, , change var.name properly, don't know how iterate on according index) if change index variable factor supposed default behavior, i.e. printing shingle levels in strip: library(lattice) index<-factor(c(1,1,1,2,2,2,2)) freq<-c(3,4,6,3,6,2,2) d<-data.frame(index,freq) histogram(~d$freq|d$index) just fun can play style variable in strip.default: histogram(~freq|index, data=d, strip = function(..., style){ strip.default(..., style = 4)} )

i'm running java application windows service , using java application, executed user, set directory used windows service application. is there way in java determine file permissions of directory user? in case, want know file permissions of windows service application while running separate java application executed user. this kind of filesystem support not available in standard java, because java cross-platform , filesystem security differs across platforms (or may not exist @ all). however, there plans add support java 7 (which have been waiting years get!) if using on windows , know c/c++, can use jni (java native interface) jna tap windows dlls , information. otherwise, can trial or paid version of jniwrapper works out-of-the-box. i'm not sure if provides support file security, provide other filesystem support - you'll need review feature list.

at work use mixture of windows , linux workstations during development. deployment deploy unix machines. i'd ensure line endings in unix format. easiest way in gradle achieve this? thinking might possible use filterreader didn't manage find ready made one. best option? editing entry use copy task instead. initial version of using tar task noticed while stripping crlf when run in linux on windows failing work correctly. since they're both copyspecs afaik have expected tar tasks work same sadly not case (gradle 1.0-milestone-3). looks i've figured out myself. filterreader required fixcrlffilter. following snippet shows how might use it: import org.apache.tools.ant.filters.*; task archiveit(type: copy) { "conf" "targetdir" filter(fixcrlffilter.class, eol:fixcrlffilter.crlf.newinstance("lf")) }

i want list of twitter followers/following of particular user, when screenname or user.id specified. can please give code snippet it? thanks. i'm author of twython. there's 2 different methods can use this; 1 returns follower ids (get_followers_ids), , 1 returns statuses/etc of follower set (get_followers_list). some example code 1 following: from twython import twython twitter = twython() followers = twitter.get_followers_ids(screen_name = "ryanmcgrath") follower_id in followers: print "user id %d following ryanmcgrath" % follower_id if have ids, you'd need further lookups yourself, latter method (get_followers_list) may want. keep in mind twython functions mirror api key parameters official twitter api docs, methods can pass argument same you'll find on docs. good luck!

i've been given xml string need put through parser. complaining because of illegal xml character. simplified example: <somexml>this & that</somexml> i know solution replace & &amp; , i'm not generating xml , therefore have no control on values. a simple string replace not right way to since '&' has special meaning in xml , global replace of '&' '&amp;' ruin special meaning intended. there solution take full xml document , 'fix' '&' become '&amp;', intended? safe globally replace ' & ' ' &amp; ' (note spaces on either side)? i think interesting question, because it's situation may happen in real-life. although believe right thing asking xml provider fix xml , make valid, thought 1 option trying lenient parser. did search , found blog post talking same problem, , suggesting same solution think of. may try jsoup . let me repeat think not

can explain me how 64 bit applications, 64bit os, , 64 bit cpu fit establish how memory addressable application? for example, how addressable memory application affected if run 64bit application on 64bit cpu, 32bit os? or 64bit cpu 64bit os , 32bit application? what happens when run 64bit application on 32bit cpu? you can't run 64-bit application on 32-bit cpu/os. a 64-bit os running on 64-bit processor has unlimited memory. address space 0 2^64, or 18.4 exabytes. a 32-bit application running on 64-bit os/processor gets 32-bit address space, 4gb. more detail: http://cnx.org/content/m13082/latest/

we attempting concatenate possibly thousands of rows of text in sql single query. query have looks this: declare @concattext nvarchar(max) set @concattext = '' update top (select max(pagenumber) + 1 #orderedpages) [#orderedpages] set @concattext = @concattext + [columntext] + ' ' (rtrim(ltrim([columntext])) != '') this working fine functional standpoint. issue we're having columntext can few kilobytes in length. result, we're filling tempdb when have thousands of these rows. the best reason have come we're doing these updates @concattext, sql using implicit transactions strings immutable. we trying figure out way of solving problem , far have 2 possible solutions: 1) concatenation in .net. ok option, that's lot of data may go across wire. 2) use .write operates in similar fashion .net's string.join method. can't figure out syntax bol doesn't cover level of sql shenanigans. this leads me question: .write work? i

i'm including forms inside html table add new rows , update current rows. problem i'm getting when inspect forms in dev tools, see form elements closed after opening (inputs, etc not included within form). as such, submitting form fails include fields. the table row , inputs follows: <tr> <form method="post" action=""> <td> <input type="text" name="job_num"> </td> <td> <input type="text" name="desc"> </td> </form> </tr> any great, thank you. a form not allowed child element of table , tbody or tr . attempting put 1 there tend cause browser move form appears after table (while leaving contents — table rows, table cells, inputs, etc — behind). you can have entire table inside form. can have form inside table cell. cannot have part of table inside form. use 1 form around

so delved singleton classes , yes, find them quite helpful. use singletons data storage multiple targets (views, tables etc.). being said, can see myself going implement lot of singletons in project. but can lot of singletons have negative impact? i've read singletons create 1 instance each of them in proces. other class instances released (assuming released properly) memory, should singletons released too? so narrow down 1 question: harmful have lot of singletons? singletons don't scale. no matter think should singleton, when system gets bigger, turns out needed more one. if never need more one, singleton fine. however, systems scale, typically need more 1 of anything within own context. singletons merely way "global". it's not bad, generally, it's not idea systems evolve , grow in complexity.
