i tasked homework assignment make task tracker. wanted learn entity framework assignment, how use inheritance aspects. projects, tasks , sub-tasks have lot of similar properties, thought use inheritance, can't figure out how query particular projects. i drew diagram in visual studio: i created database model. how can employees projects? i've started this: modelcontainer m = new modelcontainer(); var employee = (from e in m.employees e.username == username select e).first<employee>(); but ((employee)employee).projects not available, ((employee)employee).items is. ((employee)employee).items.projects not available. how employee's projects? should add navigation property employees this? you'll have use queryable.oftype(tresult) extension method in order filter entities of type manager: using (var model = new modelcontainer()) { manager manager = (from m in model.employees.oftype<manager>()

i have array of bytes representing data .wav file. want convert array of doubles, can operations such fft on determine whether 1 file contained in other. right now, cast bytes doubles, gives me decent results, not precise like. know improper conversion, , feel causing me miss data, because of difference in bytes , doubles represent. how can convert byte array double array before doing fft correlation? if each byte represents signed 8-bit sample value, data has been lost when sample recorded, , there nothing improper or imprecise casting double (which can accurately represent values byte can) - there isn't else can do.

how proxy ruby logger , keep performance? so, have requirement @ work, quite reasonable. when program sent signal hup log flushed , restarted. class localobject attr_accessor :logger def initialize context # 1 less method call! yea! performance++ @logger = context.logger end def @logger.info "hello world" end end the problem, if context.logger reset, @logger still points old one. so, thought proxy logger: class loggerproxy attr_accessor :logger def debug *args @logger.send :debug, args end def info *args @logger.send :info, args end end context.logger = loggerproxy.new context.logger.logger = logger.new 'my_file.log' signal.trap('hup') { context.logger.logger = logger.new 'my_file.log' } ... @logger = context.logger @logger.info "hello world" this works fine, except i've traded 1 method call 2 method calls (1 accessor; returns logger). still have call loggerproxy.:debug,

how can check if current running thread on gui context or not? it's unfortuntaley hard answer question 100% accuracey because it's not entirely obvious constitutes gui context. it's more of heuristic yes / no answer. , heuristic different every gui framework. for wpf 1 check , see if there active dispatcher current thread public static bool iswpfguithread() { return dispatcher.fromthread(thread.currentthread) != null; } however can fooled setting dispather on random thread not putting gui on top of it. for winforms 1 check current synchronizationcontext . public static bool iswinformsguithread() { return synchronizationcontext.current windowsformssynchronizationcontext; } however can fooled temporarily (or longer) reseting current value synchronization context. thread global , can set anyone. it's common change in applications visual studio (but that's wpf app though)

folks, have heard of problem quite time back. thought of posting it, views of doing using construct or other efficient means(specialized trees may be) given set of ranges in pairs (5,18) (12,23) (15,30) split them possible subranges seen overlapping other ranges in set. (5,11) (12,14) (15,18) (19,23) (24,30) thanks all, appreciate that... rajan... ps aa standard problem, if yes, tu know name chuck range endpoints list, mark them start/end-points. [(5, s), (18, e), (12, s), (23, e), (15, s), (30, e)] sort them position, breaking ties putting start-points before end-points. [(5, s), (12, s), (15, s), (18, e), (23, e), (30, e)] then can work out ranges iterating through list, keeping track of how many start- minus end-points we've processed far. if see start point, that's start of new range output. if our count positive, have end current range first though. if see end point, end current range.

i'm trying report number of interviews did per day. so have table of interviews such as interviewid,staffid,date,comments... and date reference table containing date 2005 2020. having single date field named ref. my query : select count(*) cnt `interviews` right join `dateref` on `date` = ref type = 2 , date > date_sub(now(),interval 7 day) group date_format(ref,'%y-%m-%d') is works fine display interview did not when did not interviews... for example returns : 1 2 4 but should return 0 1 0 2 0 4 0 edit: apparently problems comes clause because if remove it, query works fine... try replace to right join instead left join another change is where type = 2 to where type = 2 or type null so final query select count(*) cnt `interviews` right join `dateref` on `date` = ref (type = 2 or type null) , date > date_sub(now(),interval 7 day) group date_format(ref,'%y-%m-%d')

i have been testing faulty procedure, , realised problem null values being passed in not being defaulted procedure value... create procedure testvarcharmaxisnull (@myvar varchar(max) = '') select 'hello' @myvar null go exec testvarcharmaxisnull null go exec testvarcharmaxisnull '' go exec testvarcharmaxisnull go drop procedure testvarcharmaxisnull output run 1 - "hello" run 2 - "" run 3 - "" i assumed null values defaulted value assigned in stored procedure parameter, shows if exists parameter takes value pass in. there setting in sql server can change behaviour? the empty string '' not equivalent null value. so say (@myvar varchar(max) = '') means when don't pass in argument empty string in @myvar, in turn means when say where @myvar null will evaluate true when explicitly pass in null argument, in first test case.

the method in question (actually polymorphically-implemented family of recursive search methods) returns pointer type of object. had been returning nil in cases of failure. want have 2 different kinds of failure. easiest way implement that? the best way keep return nil; , take error pointer 1 of function arguments. way, can send in error, , check value afterward see happened. function still run, you'll have control on gets returned. as example, here's code use saving managedobjectcontext: nsmanagedobjectcontext *moc = [self managedobjectcontext]; nserror *error; if (![moc save:&error]) { nsstring *description = [error localizedescription]; nsinteger code = [error code]; } i've tweaked inside of block show couple of ways pull info out of error. you, it'd best use simple error codes distinguish between different nil values. here's code example (though not best way, you'll have duplicate code interpret error messages):

i have group of points (x,y) , need find out distance between 2 farthest apart. what efficient way find this? thanks well, compairing every point against every other point not efficient. the efficient way involves finding convex hull, convex polygon (no angles > 180) surrounding points. after that, find farthest points on hull, using antipodal pairs. algorithm described here: http://www.seas.gwu.edu/~simhaweb/cs153/lectures/module1/module1.html

(1) - http://blog.dynatrace.com/2009/02/09/sharepoint-lookup-value-performance/ (2) - http://www.simple-talk.com/dotnet/performance/under-the-orm-hood-revealing-the-sql/ sql server comes tool called sql server profiler . can use connect sql server instance, , you'll able see sql statements issued on server. you can filter application name, username, etc. see statements of particular application want monitor. here free express version.

say have 3 methods, similar different input types: void printlargestnumber(int a, int b) { ... } void printlargestnumber(double a, double b) { ... } void printlargestnumber(string numberasstring, string numberasstring) { ... } all 3 use same underlying logic. example: maybe double version 1 compares numbers, , other 2 convert inputs double . we imagine few different unit tests: first input larger, second larger, both inputs negative, etc. my question should 3 methods have full set of tests (black box since don't assume core implementation same) or should double version tested heavily , other 2 tested lightly verify parameter conversion (white box testing since know share same implementation , it's been tested in double tests)? if of methods public, i.e. callable outside world, i'd test of them full set of tests. 1 reason white-box tests more brittle black-box tests; if implementation changes public contract might change of methods.

i trying solve problem involves comparing large numbers of word sets , each of contains large, ordered number of words set of words (totaling around 600+, high dimensionality!) similarity , clustering them distinct groupings. solution needs unsupervised possible. the data looks like [apple, banana, orange...] [apple, banana, grape...] [jelly, anise, orange...] [strawberry, banana, orange...] ...etc the order of words in each set matters ([apple, banana, orange] distinct [apple, orange, banana] the approach have been using far has been use levenshtein distance (limited distance threshold) metric calculated in python script each word being unique identifier, generate similarity matrix distances, , throwing matrix k-mediods in knime groupings. my questions are: is levenshtein appropriate distance metric use problem? is mean/medoid prototype clustering best way go groupings? i haven't yet put thought validating choice 'k' in clustering. evaluating sse cur
