i running huge task [automated translation scripted perl + database etc.] run 2 weeks non-stop. while thinking how speed saw translator outputs (all translated sentences, info on way) stdout time. makes work visibly slower when output on console. i piped output /dev/null , thought "could there faster?" it's output it'd make difference. and that's question i'm asking you, because far know there nothing faster... (but i'm far being guru having used linux on daily basis last 3 years) output /dev/null implemented in kernel, pretty bloody fast. output pipe isn't problem now, it's time takes build strings getting sent /dev/null. recommend go through program , comment out (or guard if $be_verbose ) lines useless print statements. i'm pretty sure that'll give noticeable speedup.

i have created custom data source implementing interface jrdatasource. interface looks this: public interface jrdatasource { /** * tries position cursor on next element in data source. * @return true if there next record, false otherwise * @throws jrexception if error occurs while trying move * next element */ public boolean next() throws jrexception; /** * gets field value current position. * @return object containing field value. object type must * field object type. */ public object getfieldvalue(jrfield jrfield) throws jrexception; } my question following: in way jasper report call functions obtaining fields in .jrxml. e.g: if( next() )){ call getfieldvalue every field present in page header while( next() ){ call getfieldvalue every field present in detail part } call getfieldvalue every field present footer } the previous example, experimentally in fact found out not that. question arised. thanks! ...

first, few questions regarding databinding: is default datacontext control set codebehind? example, if have variable ordernumber in test.xaml.cs, can reference in xaml {binding ordernumber} ? is correct can databind properties of object? i have prism service in separate module/assembly import shell application via mef. i'm trying databind on doesn't appear working. my workaround below. in shell.xaml.cs: [import(allowrecomposition = false)] private iribbonservice _menuservice; public iribbonservice menuservice { { return _menuservice; } } public void onimportssatisfied() { debug.writeline("imports satisfied", "prism"); this._modulemanager.loadmodulecompleted += new eventhandler<loadmodulecompletedeventargs>(modulemanager_loadmodulecompleted); //todo figure out how bind ribbon ribbon.datacontext = _menuservice; ribbonappmenu.datacontext = _menuservice.applicationmenudata; } is there way set da...

in models have: public class bidmodel { public int id { get; set; } public string firstname{ get; set; } public string lastname{ get; set; } public int price{ get; set; } public string date{ get; set; } } where or how should define global list list<bidmodel> mylist = new list<bidmodel>; can add items in 1 controller remove items controller, change content of list wherever want.ok know work database need list of offers becase dont want queries base. in mode-view-controller, controllers responsibility hand correct model down view, depending on action calling. in mind. don't want create global list bidmodel . since using mvc 3 can pass down view quite nicely using dynamic property viewbag . consider this: public actionresult retreiveallbids() { var bids = bidrepository.getallbids(); viewbag.bids = bids.toarray(); return view(); } you of course use linq-to-* depending on orm / data storage is. might idea on how...

what secure way open odata read/get endpoint without risks csrf attacks this one? i haven't looked @ source, how msft odata library compare jquery in regard: odata designed prevent json-hijacking attack described in link returning objects json results, makes payload invalid javascript program , such won't executed browser. this independent of whether use datajs or jquery. haven't looked @ exact result jquery, know datajs "unwrap" results more natural-looking result, without artificial top-level objects. in particular, wcf data services implementation .net doesn't support jsonp out of box, although there couple of popular simple solutions add it. @ point, though, you've opted allowing data seen other domains, shouldn't done user-sensitive data.

when running hadoop in ec2, seem have 2 options: a: manage cluster myself, using ec2-specific shell scripts come hadoop. b: use elastic mapreduce, , pay little convenience. i'm leaning towards b, i'd appreciate advice people more experience. here questions: are there tasks can done 1 of these methods not other? are there other options besides these 2 i'm overlooking? if choose b, how easy go a? is, what's danger of vendor lock-in? i have been told people close amazon elastic mapreduce (emr) development team there @ least 2 other advantages using emr: a) amazon actively applying bug fixes , performance enhancements hadoop code base used on emr, , b) amazon employs high performance network between emr servers , s3 servers may not available between ec2 servers , s3 servers. update: see @mat's comments refute rumored advantages of using emr.

i know how use try-catch-finally. not advance of using finally can place code after try-catch block. there clear example? update : not great answer. on other hand, maybe is answer because illustrates perfect example of finally succeeding developer (i.e., me) might fail ensure cleanup properly. in below code, consider scenario exception other specificexception thrown. first example still perform cleanup, while second not, though developer may think "i caught exception , handled it, surely subsequent code run." everybody's giving reasons use try / finally without catch . can still make sense with catch , if you're throwing exception. consider case* want return value. try { dosomethingtricky(); return true; } catch (specificexception ex) { logexception(ex); return false; } { doimportantcleanup(); } the alternative above without finally (in opinion) less readable: bool success; try { dosomethingtricky(); succe...

is identity function pre-defined in scheme? yes, it's called values . actually, that's used multiple values, it's generalized multiple-arity identity function.
