hello working on school project in making web application. have pretty understanding 3-tier architecture, in business logic layer (bll) have no logic. using of raw data retrieve data access layer (dal) display in presentation layer (pl). in controller classes, i'm calling mapper facade classes methods without doing further. question is: is right way it, know dal must never speak directly pl , vise versa, or should call controllers else more describing? furthermore have made controller class each entity, if have methods in between 2 entities meaning access both entity classes. it pretty rare in real application database maps 1-1 presentation layer. there normalization sql databases, or denormalization nosql dbs. also, business layer needs user identity security , such doesn't map directly database representation. the last point made single controller knowing 2 entities fine. why not directly using entities in presentation layer. can mash entities ui can m...

i have seen video @ different windows, presenter follows different styles. for instance: in 1 window, uses below: employeeviewmodel evm = (employeeviewmodel)this.datacontext; evm.display(); in another, uses like: employeeviewmodel evm = new employeeviewmodel(); evm.display(); whats difference technically , best way use ? please me understand difference. the first code fragment retrieves displayed viewmodel. (it should null-check) the second code fragment creates new instance of viewmodel. because not clear display() does, hard explain difference between effect of 2 fragments second fragment (unit)test of viewmodel ignores view. there no best way far can see because both fragments serve different purpose.

i don't know how write correctly. how tried: def is_cardano_triplet(a, b, c): f = lambda x: x ** 1. / 2 g = lambda x: x ** 1. / 3 return g(a + b*f(c)) + g(a - b*f(c)) == 1 print is_cardano_triplet(2,1,5) # should true i should true 2, 1, 5 , i'm not. what's wrong function? doing bit of research and calculations, solving equation variable c , i found out that and therefore now, due floating point arithmetic being imprecise on binary-based systems known reasons , first formula pretty hard compute precisely. however, the second 1 easier compute without floating point precision errors since doesn't involve irrational functions , a , b , c integers. here's smart solution: def is_cardano_triplet(a, b, c): return (a + 1)**2 * (8*a - 1) - 27*b**2*c == 0 >>> is_cardano_triplet(2, 1, 5) true

i have 3x3 matrix: a=array([[ 1, 11, 5], [ 3, 9, 9], [ 5, 7, -3]]) i need mask minimum values in each row in order calculate mean of each row discarding minimum values. there general solution? have tried a_masked=np.ma.masked_where(a==np.ma.min(a,axis=1),a) which masks minimum value in first , third row, not second row? i appreciate help. thanks! the issue because comparison a == a.min(axis=1) comparing each column minimum value of each row rather comparing each row minimum values. because a.min(axis=1) returns vector rather matrix behaves nx1 array. such, when broadcasting, == operator performs operation in column-wise fashion match dimensions. a == a.min(axis=1) # array([[ true, false, false], # [false, false, false], # [false, false, true]], dtype=bool) one potential way fix resize result of a.min(axis=1) column vector (e.g. 3 x 1 2d array). a == np.resize(a.min(axis=1), [a.shape[0],1]) # array([[ true, false, false], #...
