if object oriented programming focused on objects, consist of methods , data, best oop-focused approach working databases, using c#? for example, want log using c# classes, , record logs in sql table. other factors being neutral, more "proper," object-oriented speaking, do: create class what's being logged, , include methods database access (the methods tied closely data) public class activity { public string activityproperty { get; set; } public void sqlmethod1() {} public void sqlmethod2() {} } ...or, create class what's being logged, , create class database access (methods not closely tied data, way data accessed treated object, i.e. referencing ef or orm) public class activity { public string activityproperty { get; set; } } public class sqlmethods { public string sqlproperty { get; set; } public void sqlmethod1(activity activityparam) { } public void sqlmethod2(activity activityparam) { } } ...or, perhaps

i'm new ios programming , i'm trying create pivot row ( or cell ) in uitableview ( know same pivot rows in ms excell ) , have main row sticks header or footer of table when scrole table , down . i've tried search solution online not find ( perhaps i'm using wrong terminology ) . know if uitableview supports such things out of box or have create custom table view . thank in advance. this not built in functionality in sense of you're thinking. there might work around depending on how many rows want. if want 1 row, override method: - (uiview *)tableview:(uitableview *)tableview viewforheaderinsection:(nsinteger)section edit: table view must have uitableview style of uitableviewstyleplain method work. then make 1 view following down scroll table view. otherwise have implement (which yield better results, , proper customization needs).

this question has answer here: could not load file or assembly or 1 of dependencies 33 answers i have package, microsoft.aspnet.web.optimization , uses antlr3 . once installed it, antlr3 came in version 3.4.1.9004 . after checking installed packages updates and, mistake, updated antlr3 3.5.0.2 . now, if remove of it, packages , reinstall microsoft.aspnet.web.optimization still error screen because it's referring newer version of antlr3 instead of old one. i tried several other things nothings seems solve problem. where can remove reference ? my main error one: could not load file or assembly 'antlr3.runtime' or 1 of dependencies. assembly's manifest definition not match located assembly reference.

i'm trying compare histogram of image (hsv) cell array contains histograms of other images in order find out closest matches. have far: image compare database: im=imread(name); resizedimage = imresize(im,[75 75]); image = rgb2hsv(resizedimage); h = image(:,:,1); [hist, colorbins]= imhist(h); hist_testing=hist'; images compare: im=imread(filename); resizedimage = imresize(im,[75 75]); image = rgb2hsv(resizedimage); h = image(:,:,1); data {i,1}= histogram(h); the histogram class represented this: function [hist] = histogram(h) [hist, colorbins]= imhist(h); hist=hist'; end through pdist2 method usage: comphist= pdist2(hist_testing, hist, 'euclidean'); the error gives me "not enough arguments input". can please me?

currently developing solution in field of time-series data. within these data have: id, value , timestamp. here comes: value might of type boolean, float or string. consider 3 approaches: a) every data type distinct table, sensor values of type boolean table, sensor values of type string another. obvious disadvantage have know sensor. b) meta-column describing data type plus values of type string. obvious disadvantage data conversion e.g. calculating max, avg , on. c) having 3 columns of different type 1 value per record. disadvantage 500000 sensors firing every 100ms ... plenty of unused space. as knowledge limited appreciated. 500000 sensors firing every 100ms first thing, make sure partition properly, make sure don't exceed limit of 2 billion columns per partition. create table sensordata ( stationid uuid, datebucket text, recorded timeuuid, intvalue bigint, strvalue text, blnvalue boolean, primary key ((stationid,datebucket),recorded)

i new elm , functional programming in general. using elm , need function has signal (list string) input , returns list (signal string). i know shouldn't have problem better architectural design in program having function solve big problem me. the combine function opposite: combine : list (signal a) -> signal (list a) combine = list.foldr (map2 (::)) (constant []) i've tried similar combine function have been unsuccessful far. ideas on how create such function? this not possible in general the inverse of combine not (in general) possible. when have list of static size of signals, can combine them signal of lists of static size. when go other way, there no guarantee lists in signal static size. therefore cannot "just" construct list out of it. (if normal value of type list have changing size without showing signal around type, , dynamically creating , destroying signals in list. 2 things elm disallows. ) but restrictions... of course

will node.js app on bluemix automatically scaled run on multiple processors, or need implement myself using node's clustering api? , if use clustering, there more 1 cpu available? short answer: need use node cluster module take full advantage of cores in each instance. or, can increase number of instances. long answer: each instance of application push bluemix runs in warden container. resource control managed linux cgroups. number of cores per instance not can control. running quick test on bluemix, os.cpus() showed 4 cores. if want take advantage of 4 cores, in 1 bluemix instance (warden container) of node.js application, should use nodes cluster module. keep in mind, can increase number of instances (horizontal scaling), achieve near linear results depending on bottleneck on use of external services. if have 3 instances, each of instances has 4 cores, , built-in load balancer distributes traffic among 3 instances.

this question has answer here: regex: how escape backslashes , special characters? 1 answer i trying replace " \" in java, slashes getting confusing. proper way replace " \" in java? string.replaceall("\"","\\""); if going replace literals don't use replaceall replace . reason replaceall uses regex syntax means characters treated specially + * \ ( ) , make them literals need escape them. replace adds escaping mechanism automatically, instead of replaceall("\"", "\\\\\"") you can write replace("\"", "\\\""); which little less confusing.

i working on project 100+ pages , using angularjs ui-route , php rest backend. authentification want use json web token. i trying find best way make login page, didn't found way still, after lot of googling. my app allows logged in users access it, else should go login page. my main problem how should organize index.html because login page has totally other template rest of app. in index.html have lot of elements header , footer loaded on pages, except on login page. in order achieve used ng-if={{user.isloggedin}}, it's not right thing do, think, because 1 page must have condition on pages. another idea use 2 apps, if user not logged in redirected login app (actually redirection, not change of state, because uses master template). is there way in keep login page in spa, have 1 app? thanks in advance valid answer , hope i've been clear possible. look nested views ui-route. able have $state.login , $state.dashboard state while logged in follow $stat

i'm evaluating springxd , wondering if there limitations current functionality provides. couldn't find documentation on , i'm sure answer falls under "it depends" category, thought ask anyways. examples of mean are: is there max limit on number of streams can created? (i'm guessing not these seem backed database answer may depend on streams doing) is there max limit on number of named channels can created? (i'm guessing may depend on underlying mom used message passing) is there max limit on number of nodes (xd-node or xd-admin) can running in system? (i'm guessing depends on zookeeper , on how many connections underlying mom allows) etc. so speaking, there limitations of potential use cases people should aware of before picking springxd? thank you, aaron edit answer @dturanski the situation i'm thinking of having potentially large number of streams (technically unbounded). i'm talking minimum of maybe couple thousand in be
