if using raw sockets send udp packet of size 3000bytes, need handle packet fragmentation myself in code, or should raw socket handle fragmentation similar dgram socket? well, if using udp, aren't sending raw. raw no ip @ all, in case yes have handle fragmentation yourself. with udp ip's fragmentation support, imho plenty enough short-haul networks collisions should minimal. make link between 2 systems dedicated subnet, , isn't issue @ all. what tcp buys on udp (among other things) stack's ability have resend 1 fragment if gets lost or hosed somehow. udp if happens entire message must discarded. there's overhead though, , modern networks can live trade-off.

when developing eclipse plugin, best way set problemmarker empty ifolders? trying achieve following: im using own project type, , want folders in package explorer marked , decorated warning when empty. what can add markers when opening eclipse. dont know how update markers when changes occur. i tried way: using method : public void resourcechanged(iresourcechangeevent event) (is called whenever in workspace changed) i checking folders if empty (works) then adding problemmarker on ifile instances. (does not work, because adding problemmarker locked while being in method resourcechanged) because changing markers fires resourcechanged event. so usual way solve problem? guess there 1 because in eclipse whenever change in package explorer decorators updated instantly. you try create builder checks problems , creates markers needed. this article you

return self.var[:] what return? python permits "slice" various container types; shorthand notation taking subcollection of ordered collection. instance, if have list foo = [1,2,3,4,5] and want second, third, , fourth elements, can do: foo[1:4] if omit 1 of numbers in slice, defaults start of list. instance foo[1:] == [2,3,4,5] foo[:4] == [1,2,3,4] naturally, if omit both numbers in slice entire list back! however, copy of list instead of original; in fact, standard notation copying list. note difference: >>> = [1,2,3,4] >>> b = >>> b.append(5) >>> [1, 2, 3, 4, 5] >>> >>> = [1,2,3,4] >>> b = a[:] >>> b.append(5) >>> [1, 2, 3, 4] this occurs because b = a tells b point same object a , appending b same appending a . copying list a avoids this. notice runs 1 level of indirection deep -- if a contained list, say, , appended list in b , still change a . by way, the...

i have context menu gets menu items through databinding (i'm using mvvm pattern): <contextmenu itemssource="{binding path=contextmenuitems}" /> this works fine. however, in cases when there no menu items show, don't want context menu show @ all. there way accomplish this? kind of xaml trigger maybe? i've tried catching opened event och closing context menu when there no children. works context menu still flashes by... maybe bind menu items collections count property , use converter set context menu's visibility. <contextmenu itemssource="{binding path=contextmenuitems}" visibility="{binding path=contextmenuitems.count,converter={staticresource zerotohiddenconverter}}"> public class zerotohiddenconverter:ivalueconverter { public object convert(object value, type targettype, object parameter, system.globalization.cultureinfo culture) { int count = (int) value; if (...

i have assignment create algorithm find duplicates in array includes number values. has not said kind of numbers, integers or floats. have written following pseudocode: findingduplicatealgorithm(a) // array mergesort(a); int <- 0 i<a.length if a[i] == a[i+1] i++ return a[i] else i++ have created efficient algorithm? think there problem in algorithm, returns duplicate numbers several time. example if array include 2 in 2 two indexes have ...2, 2,... in output. how can change return each duplicat 1 time? think algorithm integers, work float numbers too? to handle duplicates, can following: if a[i] == a[i+1]: result.append(a[i]) # collect found duplicates in list while a[i] == a[i+1]: # skip entire range of duplicates i++ # until new value found

i have wpf intranet app running in trusted mode (local only). users able upload image , attach article on newsletters section. having trouble deciding these images stored. please provide me opinions. @ present have few ideas myself; have aspx page runs parallel app, , run inside browser(i-frame). page handle upload , display of image. also, have users copy directly network share. seems there should more elegant sollution not aware of. ideas? don't force solution towards aspx because know how there. it's unnatural build page, host browser show page etc, upload image. it's quite simpler in desktop client on web page. have "load file dialog" - use filepath user wants upload, , when have can either: copy (inside application) share, or if have service - send through method call, or can store inside database (recommended if files small) there's lots of options here... depends if client has connection db, have service in between, etc...

i know long shot, have huge text file , need add given number other numbers matching criteria. eg. identifying text 1.1200 identifying text 1.1400 and i'd transform (by adding 1.15) to identifying text 2.2700 identifying text 2.2900 normally i'd in python, it's on windows machine can't install many things. i've got vim though :) here simplification , fix on hobbs' solution: :%s/identifying text \zs\d\+\(.\d\+\)\=/\=(1.15+str2float(submatch(0)))/ thanks \zs , there no need recall leading text. str2float() single addition done on whole number (in other words, 1.15 + 2.87 give expected result, 4.02, , not 3.102). of course solution requires recent version of vim (7.3?)

i have tab control each tabitem usercontrol. i'd hold usercontrols in tabcontrol's itemssource. itemssource list go in window's viewmodel? if so, feel it's breaking mvvm since viewmodel have gui controls within it. or put list in codebehind of window holds tab control? any suggestions great! with tab controls, more not individual tabs created statically in xaml rather @ run time data binding. there no reason why shouldn't this. if have collection of views, should stored in view. bear in mind bind itemssource list of viewmodels objects , wpf generate view itemtemplate, viewmodel object set datacontext. collection of viewmodels should stored in view model, although @ point view model have stored in view.

i have bunch of internet devices communicate mvc app on iis 7.5. i'm using built-in dynamic transparent compression (gzip/deflate). i'd able support different compression algorithm, lot better gzip (7zip) content i'm sending/receiving. in other words, on client add header: accepts: gzip, deflate, 7zip (or similar), , server recognize this, , apply best choice when sending content. what's best way go hooking together? (i know how implement actual 7zip encode/decode aspect) thanks. on server side, can compress responses using httpmodule . httpmodule similar global.asax in exposes request , response lifecycle events beginrequest, releaserequeststate, , endrequest. can alter contents of response handling appropriate event , changing output stream. typically alter response attaching output filter . example, the blowery httpcompress module(no longer updated) attaches compression filters in releaserequeststate or presendrequestheaders events: http://...

i want iterate on list of dom elements (check boxes) , keep going long list defined. elements 'c1r1', 'c1r2', 'c1r3', etc. once hit undefined one, stop. problem seems using typeof dom elements. here's offending code: function domisdefined(idstring){ alert(idstring); var isitdefined = (typeof $(idstring) != 'undefined'); alert(isitdefined); return isitdefined; } ... for(i=1; domisdefined('c1r' + i); i++){ if($('c1r' + i).checked==true){ // stuff } } the crux of problem line: var isitdefined = (typeof $(idstring) != 'undefined'); the problem, found out, typeof $(idstring) returns object, whether defined or not. there way sort of thing? guess i'll put in try catch , check .checked property early, feels disgusting. function domisdefined(idstring){ return !!document.getelementbyid(idstring); }

in code, every time need new object attribute class, typically copy/paste name in 4 different places! the declaration in header file ( nsobject * myobject; ) the @property() line the @synthesize() line in implementation releasing under dealloc: (only objects of course) i because works, not because understand what's going on. know declaration in header file allows other classes see attributes, property specifier determines how getter/setter methods constructed. , synthesize line builds getter/setter methods. know primitive types should use ( nonatomic,assign ) instead of ( nonatomic,retain ), have no clue when should omit nonatomic. what can avoid redundancy in code. if change or add variable in class have check 4 different places, , gets old fast. there key strokes make process faster? there lines of code can simplify or combine obtain same result? accessorizer automate lot of you.
