when trying load page times out after time , have no idea how edit query , fix problem. the sql follows: <createtemptable nml-type="string"> declare global temporary table temp_tdt (subject_id_num bigint) on commit preserve rows not logged replace </createtemptable> the dataset not long @ still times out. there has never been problem having no index in past, loaded data no problem, instead of loading data times out first time , goes loading fast. sql written in websphere in xlm file. looking more efficient way. we're missing lot of detail here. either temporary table created every user (every new connection) or every app restart, plus there no indexes on temp table. do timeouts occur on first invocation or after while? best change proper table indexed , if timeouts, analyse queries run against it.

okay writing simple little stringbuilder, curious how add after arguments. example if do: args[0] = "how" args[1] = "do" args[2] = "i" args[3] = "google" how make output this: "how+do+i+google", without plus @ end of last argument? this have far. stringbuilder sb = new stringbuilder(); (int = 0; < args.length; i++){ sb.append(args[i]).append(" "); } string allargs = sb.tostring().trim(); with pre-jdk8 can use guava's joiner : return joiner.on("+").skipnulls().join(args); for jdk8, @chengpohi seems enough, little correction: return string.join("+", args); to extend op code: stringbuilder sb = new stringbuilder(); (int = 0; < args.length; i++){ sb.append(args[i]); if(i != (args.length - 1)) { sb.append('+'); } } string allargs = sb.tostring().trim();

consider following code (i know have past 30 minutes): [1] pry(main)> durhamscraper::tweet => durhamscraper::tweet [2] pry(main)> object.const_get("durhamscraper::tweet") nameerror: wrong constant name durhamscraper::tweet (pry):2:in 'const_get' [3] pry(main)> string => string [4] pry(main)> object.const_get("string") => string durhamscraper::tweet class loaded (as can infer line 1). no exceptions raised when ran code earlier. change when code executed changed repository name. advice on how debug further, or how may solve this? per ruby 2.1.1 documentation: this method recursively constant names if namespaced class name provided. the issue when changed directory's name, no longer using ruby 2.1.1 , instead using ruby 1.9.3. if object.const_get not work expect, make sure check ruby version , corresponding documentation. for earlier versions of ruby not allow namespaced class names, can walk hierarchy, kardeiz s

i working class uses reference ef in constructor. i have implemented idisposable , i'm not sure if need destructor because i'm not can classify ef unmanaged resource. if ef managed resource, don't need destructor, think proper example: public exampleclass : idisposable { public exampleclass(string connectionstringname, ilogger log) { //... db = new entities(connectionstringname); } private bool _isdisposed; public void dispose() { if (_isdisposed) return; db.dispose(); _isdisposed= true; } } if ef unmanaged, i'll go this: public exampleclass : idisposable { public exampleclass(string connectionstringname, ilogger log) { //... db = new entities(connectionstringname); } public void dispose() { dispose(true); } ~exampleclass() { dispose(false); } private bool _isdisposed; protected virtual void dispose(bool di

i have winform app in main form has tabcontrol, 1 thread create or remove tabpages frequently.and other background threads data , need visit each tabpage's control inside it. code here , can work: public void getcustomermessage() { if (this.tabcontrol.invokerequired == true) { customerinforhandler handler = getcustomermessage; this.tabcontrol.invoke(handler); } else { //code update in tabpages //with foreach tabpage in tabcontrols , use begininvoke } } the problem is, realize in fact background thread need visit tabpage, not tabcontrol, right check invokerequired property of tabcontrol, or need check each tabpage's invokerequired ? because feel ui block short time. is mean when tabcontrol can visit ui thread, not equals tabpage

in stack overflow answer demonstrated aliasing in c++ can slow down code. , aliasing in c++ doesn't apply pointers, applies references, , more these types specified standard . particularly, there an aggregate or union type includes 1 of aforementioned types among members (including, recursively, member of subaggregate or contained union) so according understanding, if have code below, class a{ public: int val; }; void foo(vector<a> & array, int & size, & a0) { for(int i=0;i<size;++i) { array[i].val = 2*a0.val; } } and possible a0 can alias 1 of elements in array , possibly alias size because of aforementioned quote, a0 , size have loaded each iteration resulting in performance drop. then question should code avoid aliasing, , improve performance? passing const & won't since won't avoid aliasing specified standard. pass a0 value? make copying of a0 don't like, since in practice, class a may comple

according spec , there various cache modes fetch api. ("default", "no-store", "reload", "no-cache", "force-cache", , "only-if-cached") however, isn't clear each mode for, or state of browser support. you can see documentation of polyfill here: https://fetch.spec.whatwg.org/ it explain each value means "default" fetch inspect http cache on way network. if there fresh response used. if there stale response conditional request created, , normal request otherwise. updates http cache response. [http] "no-store" fetch behaves if there no http cache @ all. "reload" fetch behaves if there no http cache on way network. ergo, creates normal request , updates http cache response. "no-cache" fetch creates conditional request if there response in http cache , normal request otherwise. updates http cache response. "force-cache" fetch uses
