i'm developing application need communicate running on different machines located in different locations. going use tcplistener , tcpclient send information between applications came across msmq. the computers connected via software vpn, communicates across standard internet connection now don't know technology use, tcpclient or msmq. i want send different types of information requests , transmit files. have large amount of data in database large send across internet application. want send request 1 app other run query, save results xml, compress it, , send file back. receiving application decompress , load xml data set, saving great amount of time. (uncompressed 10mb+, compressed 0.3mb) there different types of requests information. so, want application able differentiate between requests, i'm not sure how best receive information , then determine information is, (i.e. type of request is) are situations 1 technology better other? any pointers how best impl...

in objective-c have timer fire every 0.1 seconds , increment double value (seconds) 0.1. so should keep time counting 1/10 of second. when fires checks if - else statements see if time (seconds) equal 3, 9, 33, etc., these never triggered. suppose because of way doubles represented in bits, decimal approximation , never whole number. how can fix statements triggered? -(void)timeseconds:(nstimer*)thetimer { seconds = seconds + 0.1; nslog(@"%f", seconds); if (seconds == 3.0) { [player pause]; [secondstimer invalidate]; } else if (seconds == 9){ [player pause]; [secondstimer invalidate]; } the floating point types cannot represent numbers exactly, when these added, error compounded , floating point type becomes less , less precise. use integral type represent time difference using greater resolution, example, use nsuinteger represent milliseconds instead of seconds, , increment 100 instead of 0.1. instead of comparing seconds == 3.0 , use ...

i've got question reusing table data view won't work in scenario have parameter needs passed in. part of system requires travellerid sent procedure , list of arrangers returned specific traveller. there around 7 business rules used determine arrangers can returned , mutually exclusive, in order accommodate these optional rules have used series of unions inside derived query. working well, , performance seems across large database, need reuse these rules (unions) in 4 other parts of system. i tried create view these unions didn't work due differing logic in each union , different parameter requirements, thinking maybe function solve issue? if created function took @travellerid param , returned list of arrangerid based on business rules, ideal/fast solution? using union , distinct in outer query proved faster using union's uniqueness of data. current procedure business rules below (sql server 2008): create procedure [dbo].[getarrangersfortraveller] @travel...

i have section in website called recent updates. in show latest 5 updates @ first when page rendered. when new update done @ real time, new update appended top of updates list , last 1 deleted. my approach: for problem, im doing is, first renders page last 5 recent updates. fetching updates database. when update made in realtime, stored in database flag = 0. to find out whether update made, have javascript calls ajax page every 4 seconds. ajax page checks in db whether records flag=0 present. if of there, return update flag=0 , set flag 1. problem: it working fine on single system. havent tested on multiple system @ same time. i fears, each update can viewed single user , flag set 1. other users may not it. is there alternate approach in solving issue?. may changing query or may yield goodness. expecing experts here.. appreciated. each update stored timestamp of when created. javascript figures out timestamp of latest update displayed on site. ajax requ...

i have following setup. 'apps/reports' <---------> 'db2 connect' <------------> 'legacy db2 on as400' `hibernate` `native calls` when data retrieved application, padded spaces if length less column length. of note when running query, if where cause parameter not padded, automatically padded spaces such query retrieve same records padded , non-padded parameter. is there way (preferably on ibm db2 connect or connection string parameter) remove whitespaces resultset? are columns in iseries defined char()? i'm assuming so, because how char() works -- it's fixed field length, not variable field length (that's varchar for).

my department pushing me use vm slices out qa , uat testing. believe should using identical physical hardware prod. our prod setup uses 5 high-spec servers. qa there 5 vm slices on single high-spec machine. apart performance difference i’ve experienced .net runtime crashes on vm slices haven’t experienced on physical machines (see this: net runtime bug : .net runtime 2.0 error - event id: 1000 crashed program. caused this? ) does else have opinion on this? vm slices or on physical machines qa? /cost isn’t issue here. correctness is. having done considerable qa/uat work, can preferable have test machine matching hardware specs. you can (and have) done qa/uat work on vm's , these should adequate testing. exception load/stress testing.

for(x;x<crap;x++) { macro(x,y); } how handled preprocessor? loop unrolled or else? the macro expanded before code compiled - doesn't matter whether it's in loop or anywhere else. #define macro(x, y) dosomething(x, y) for(x;x<crap;x++){ macro(x,y); } will expand to: for(x;x<crap;x++){ dosomething(x,y); } the context surrounding macro(x,y) has no effect on how preprocessor expands it.

let's taking video (with camera in steady position) , bird flies through view of camera. should possible image segmentation , automatically remove bird video. what these styles of algorithms called , how accomplished? there's technique called simple image object extraction (siox) - uses technique identify foreground vs. background objects in still , video images. open source gimp editor has implementation of it, , there's more information here . from overview: siox stands simple interactive object extraction , solution extracting foreground still images little user interaction. siox fast, noise robust, , can therefore used segmentation of videos. avoids many of drawbacks of graph-based segmentation methods performs equally on different benchmarks. siox open , free (apache license) , authors have intentionally not patented part of technology. result, has been integrated several open-source image manipulation programs on past years. siox underlying a...

i have 2 tables querying on date column in each table. in 1 case need use trunc() function on date field values back, on other not. that works on table 1: select to_char( datecol1 ,'mm/dd/yyyy hh:mm:ss') table1 datecol1 =to_date('10/07/2010', 'mm/dd/yyyy'); but on table 2 above syntax did not work , needed trunc(), such as: select to_char( datecol2 ,'mm/dd/yyyy hh:mm:ss') table2 trunc(datecol2) =to_date('10/07/2010', 'mm/dd/yyyy'); three things note: in querying table1 to_char(datecol1 ,'mm/dd/yyyy hh:mm:ss') looks if times between 12:00 , 12:10, values inserted throughout day when inserting records table1 insert mm/dd/yyyy, no time when inserting records table2 inserted time so can explain: why truncate not needed on table1 on table2? why values in table1 between 12:00 , 12:10? in table1 have no 'time-of-day' component data, date should match - observed. but, used mm formatti...

i'm having weird problem: when program reach method: //returns transpose matrix of 1 regmatrix regmatrix::transpose() const{ regmatrix result(numcol,numrow); int i,j; for(i=0;i<numrow;++i) for(j=0;j<numcol;++j){ result._matrix[j][i] = _matrix[i][j]; } return result; } it crashes... when ran vs debugger, looked fine, new matrix filled relevant values, till line return result; mysterious reason returned empty matrix vector. where go wrong?? here implementation copy constructor: //cctor of regmatrix regmatrix::regmatrix(const regmatrix &other): numrow(other.getrow()), numcol(other.getcol()){ //create _matrix = vector<vector<mydouble> >(other.getrow()); int i,j; for(i=0; < numrow; i++) _matrix[i] = vector<mydouble>(other.getcol()); //copy matrix for(i=0;i<numrow; ++i){ for(j=0;j<numcol; ++j){ _matrix[i][j] = o...

as migrating project public source hosting, wanted remove “personal” information svn repository. did fine far removing paths or revisions using svndumptool , svndumpfilter . want remove text particular file in repository well. i removed text manually regex’ing dump , worked fine, when want use dump, checksum mismatch. because changed file didn't update checksum. is there tool recalculates checksum files in dump? or there good editing tool files (should allow regex replacements) inside svn dump updates checksum? okay, didn't want wait longer answers, wrote script myself, share you. utilizes svndumptool , or rather library. custom actions required edit source (and know bit python). simple example included , think abstraction script provides quite good. anyway, hope useful me, although took me quite while working that: svndumptooledit.py on github.

here's simplest form of question: iapple requires, among other things, property flavor itoffeeapple requires property flavor the problem is, want itoffeeapple implement iapple (public interface itoffeeapple : iapple), both have same property requirement. becomes problem when, 1 purpose need collection of sweets (only itoffeeapple) itoffeeapple can recognised iapple. is ok use "new" keyword in interface, implementers have 2 flavor properties? have explained myself poorly? :\ edit: have. actual context geometry: iline requires start , end point ipoint. icurve requires start , end point icontrolpoint. icurve functionality on top of iline, yet means want return start , end icontrolpoint rather ipoint, either implement both , have return of both icontropoint , ipoint of start , end, or ignore ipoint/iline , throw dry out window. this elaboration of david culp's answer. it's quite long, i'm not posting comment. while generic interface...

in iphone app, made custom uiview use in several different view controllers display information. i'm familiar making customer table cells use in table i've never made custom view again. my question best way load view? i've tried placing view in view controllers want appear in using ib, doesn't seem enough. seems me make sense if set class identity view should load view when view controller created. or maybe doesn't because doesn't know nib (it's in own nib, of course). since it's not view controller, can't use initwithnibname. i've tried using nsbundle loadnibnamed table cells seems awfully large amount of work. code looks this: nsarray *toplevelobjects = [[nsbundle mainbundle] loadnibnamed:@"mycustomview" owner:nil options:nil]; (id currentobject in toplevelobjects) { if ([currentobject iskindofclass:[mycustomview class]]) { self.customview = currentobject; break; } } [self.view addsubview:self.custo...
