i'm translating stuff matlab python language. there's command, unique(a), in numpy . since matlab program runs 'rows' command also, gives little different. is there similar command in python or should make algorithm same thing? assuming 2d array stored in usual c order (that is, each row counted array or list within main array; in other words, row-major order), or transpose array beforehand otherwise, like... >>> import numpy np >>> = np.array([[1, 2, 3], [2, 3, 4], [1, 2, 3], [3, 4, 5]]) >>> array([[1, 2, 3], [2, 3, 4], [1, 2, 3], [3, 4, 5]]) >>> np.array([np.array(x) x in set(tuple(x) x in a)]) # or "list(x) x in set[...]" array([[3, 4, 5], [2, 3, 4], [1, 2, 3]]) of course, doesn't work if need unique rows in original order. by way, emulate unique(a, 'columns') , you'd transpose original array, step shown above, , transpose back.

'exception unhandled' error in visual studio. public keyvalueconfigurationcollection getmyappsetting() { configuration config; configurationfilemap configfile; try { configfile = new configurationfilemap(configurationmanager.openmachineconfiguration().filepath); config = configurationmanager.openmappedmachineconfiguration(configfile); appsettingssection myappsettingsection = (appsettingssection)config.getsection("xxx/appsettings"); myappsettingsection.sectioninformation.allowexedefinition = configurationallowexedefinition.machinetoroaminguser; return myappsettingsection.settings; } catch (exception ex) { logger.fatal("..."); throw; } } this method belong class library, , call console application. please, me. thanks. it working expected. you catch, rethrow exception - not handling rethrown exception. that's why getting error.

i've tried following, input: lat/lon data i'll calculate box around by, let's 50 m, +/- 50 m on easting/northing value. now reconvert lat/lon , script: http://robotics.ai.uiuc.edu/~hyoon24/latlongutmconversion.py result can't be, lon before around 7, afterwards around 2. zone, easting, northing = lltoutm(23, location.get_lat(), location.get_lon()) toputm = northing + error bottomutm = northing - error leftutm = easting - error rightutm = easting + error left, top = utmtoll(23, leftutm, toputm, zone) is error in code, or might script flawed? so i've tried use pyproj, lat/lon utm lat/lon see happens >>> p = pyproj.proj(proj='utm', zone=32, ellps='wgs84') >>> p <pyproj.proj object @ 0x7ff9b8487dd0> >>> x,y = p(47.9941214, 7.8509671) >>> print x,y 5159550.36822 1114087.43925 >>> print p(x,y,inverse=true) (47.971558538495991, 7.8546573140162605) and here it's not extremely far of...

i need confirmation. correct o/p told me following expression not work thanks in advance. #define 11 #define b 12 #define c 13 // want if array[i] has values of of these if( array[i] == (a) ||(b) ||( c)) // function else printf("no match"); replace code this: if( array[i] == || array[i] == b || array[i] == c) each part of boolean condition must complete expression. while wrote valid c code, doesn't achieve want: need make array element comparison in every part.

i have taken position @ large corporation web developer 1 of company's divisions. first task have been asked create web form submits data database , outputs id# of data user reference later. easy, right? unfortunately not. because large company has been around long time systems relatively antiquated , none of servers support server-side technologies (php, asp etc...) , since such large company corporate pretty black hole , there not hope of getting such tech implemented. so! question... there way without server-side? me answer 'no' , have spent last week researching on sites , others without finding miraculous work arounds. have @ disposal things can implement without involving it, things can upload web-server. also note: web server on supposedly ibm web server (ihs) , database supposed connecting ms access database , company restricts using ie web access. form on internal company intranet site ie browser accessed from. i know ridiculous situation unfortunately st...

this perhaps question of semantics, perhaps not, ask: there appreciable difference in following 2 snippets? public parent() { child newchild = new child(); newchild.requestspecialevent += (sender, e) => { newchild.domagic(); } } or public parent() { child newchild = new child(); newchild.requestspecialevent += (sender, e) => { ((child)sender).domagic(); } } obvious difference option 1 sort of self-references itself, while option 2 performs cast on object. performance wise, expect cast more expensive. however, i'm theorizing in option 1, technically "parent" holds reference "newchild" (through delegate defined within parent), if newchild goes away (newchild = null or similar), newchild object can't garbage collected (gc'ed) because parent has defined delegate still attached it. newchild can gc'ed when parent goes away. however, in option 2, parent never creates such "hard refer...

i have vector of floats, defined by: std::vector<float>* myvec; and filling inside loop later with: myvec->push_back(somevalue) and getting seg fault. in order try , find out going on commented out push_back line , still saw seg fault, , when seg faulted size of myvec 490618047. is there perhaps have forgotten vector, , how getting filled such huge number without entries being entered vector? thanks in advance. you've not allocated memory: std::vector<float>* myvec = new std::vector<float>(); because myvec pointer std::vector<float> , you've above, before using myvec . also, don't forget deallocate memory, once you're done myvec : delete myvec; apart that, i think , don't need pointer begin with; if so, should following instead of declaring pointer: std::vector<float> myvec; //it not pointer. and use as: myvec.push_back(somefloatvalue);

i created ef4.1 code-first model (may or may not important), , i'm trying default values create scaffold template. model looks like: class person { [defaultvalue (18)] public int age { get; set; } } and create view looks like: <div class="editor-label"> @html.labelfor(model => model.age) </div> <div class="editor-field"> @html.editorfor(model => model.age) @html.validationmessagefor(model => model.age) </div> i expect @ runtime, editorfor pre-populate textbox "18", no such thing. misunderstanding defaultvalue attribute for, or there else should doing? note: don't want use new { value = "18" } override on editorfor method, seems break dry. i don't know if satisfy dry needs, it's start think. i rework model bit this: public class person { private const int default_age = 18; private int _age = default_age; [defaultvalue(default_age)] pu...

i have widget provide boot loader put on website. bootloader file gets settings widget , creates widget. content of bootloader file doesn't change unless widget edited, means of times bootloader file has static content. however right bootloader file created dynamically every request. save settings widget in database , serve file. size of file 6kb. wondering better: save data in database , serve bootloader file dynamically, save data in static javascript file or store data in database , store data in javascript file (this allows later updates in corrupted javascript files) also, wondered if stored static js file .js.gz (compressed) , .js(uncompressed) how serve uncompressed file when browser not support compressed file...could same done if dynamic bootloader file used. the bootloader file used json content processed bootloader file , displayed, means bootloader file better if cached prevent getting js on , on again. so ->how should file stored? ->how difference in ...

i reading book prep interview , came across following question: what when crawler runs honey pot generates infinite subgraph wander about? i wanted solutions qn. personally, form of depth limited search prevent traversing continuously. or perhaps use form of machine learning detect patterns. thoughts? most commonly infinite subgraphs prevented link depth. gain inital set of urls , traverse each finite depth. while limiting traversing depth may use heuristics dynamically adjust according webpage characteristics. more information can found e.g. here . another option try sort of pattern matching. depending on algorithm produces subgraph pretty (very very)hard task. @ least pretty expensive operation. for interview question(about detecting infinite loops): if ask questiom want hear reference halting problem alan turing proved in 1936 general algorithm solve halting problem possible program-input pairs cannot exist.
