how run xunit.net unit tests monodevelop? have version 5.9.6 installed on lmde , have installed xunit.net testing framework support add-in. have test project installed xunit.net nuget package , wrote test in it. afaik have set correctly. however, unit tests pad empty , can't run tests run -> run unit tests. know need test runner, can seem find 1 visual studio. have runner , not know it? i've never set testing environment before , @ loss else need do. edit i have found xunit.net console runner , installed it. can run tests console runner , can debug tests run -> debug application... however, tests still not recognized within monodevelop , still not show in unit tests pad. i run xunit-tests under monodevelop add-in. i noticed when have referenced unit-test framework in project, no tests appear in pad. try remove nunit.framework reference.

when i'm getting list of results in cordova app, want roll specified element function: $scope.roll = function () { //var rankscroll = $ionicscrolldelegate.$getbyhandle('rank'); var meelement = document.getelementbyid('scroll'); if (!meelement) { $ionicscrolldelegate.scrollto(0, 0); return; } var top = meelement.getboundingclientrect().top - 50; $ionicscrolldelegate.scrollto(0, top); console.log(top); console.log($ionicscrolldelegate.getscrollview()); } it works nicely, can't scroll other place in list. want unlock scrolling in solution or find better one. should scroll on page loaded, not on click. all best that function lock scroll because of $scope's binding. if want function invoked when view loaded, should call once @ the time view loaded. you can way in controller: var roll = function () { //var rankscroll = $ionicscrolldelegat

consider have 2 lists (or columns in pandas dataframe), each containing null values. want single list replaces null values in 1 list corresponding non-null values of other if 1 exists. example: s1 = [1, nan, nan] s2 = [nan, nan, 3] ## function result = [1, nan, 3] assume if both lists non-null @ position match, need not worry resolving conflicts. if so, know can solve list comprehension: [x if ~np.isnan(x) else y (x,y) in zip(s1,s2)] or if s1 , s2 columns in pandas dataframe df, can use similar logic , apply function: df.apply(lambda x: x.s1 if ~np.isnan(x.s1) else x.s2, axis=1) but there cleaner way this, perhaps using of pandas functionality? kind of operation called? kind of union, preserves ordering , null values when lacking alternative. i had recently. may have adapt put below depending on structure of column values. import pandas pd # example dataframe df = pd.dataframe({'col': ['a', 'b', none, 'd', 'e', none,

observation: i executing same query through .net code using cmd.executenonquery() , directly in sql server management studio passing parameter values. when execute through code runs long time (15-20min) whereas when execute in sql server same parameters completes within few seconds. the reason taking longer time performance issue of query , solved introduction of non-clustered indexes in 1 of tables. i still wonder, why taking few seconds earlier sql server although environmental conditions same. due difference in execution plan? idea?

i have main class swaps in few different fragments. fragments have invoke methods on parent activity class, therefore activity , fragments tightly coupled. worthwhile or better practice decouple these or fragments commonly coupled parent activities?

the output of following codeblock 'false'. why? byte[] = {1,2,3}; byte[] b = (byte[]) a.clone(); system.out.print(a==b); == identity operator in java. means, checks if 2 objects same thing. it's not logical equality, it's not containing same values. it's being same object. in example, not same object. clone method of array creates new object, same content original. new object have same content, have own identity. it's new object, distinct original. in contrast, equals method logical equality. is, 2 objects containing equal values. when cloning array, original , clone equal, because have same values. not identical, because have different identities. in terms of java's == operator , contract of equals method: if 2 arrays equal, not identical if 2 arrays identical, equal the importance of identity when 2 array variables have same identity (both pointing same object), modifying 1 of them appear modify both of them. when 2 arrays equ

i've declared number of variables @ start of script, i'm using them in number of different methods ("functions" in python?). when try access them, can't seem value = or set them value matter. example: basefile = open('c:/users/<redacted>/documents/python dev/atm/data.icsf', 'a+') secfile = open('c:/users/<redacted>/documents/python dev/atm/security.icsf', 'a+') def usrinput(raw_input): if raw_input == "99999": self.close(true) else: identity = raw_input def splitvalues(source, string): if source == "ident": usrtitle = string.split('>')[1] usrfn = string.split('>')[2] usrln = string.split('>')[3] x = string.split('>')[4] usrbal = decimal(x) usrbaldisplay = str(locale.currency(usrbal)) elif source == "sec": usrpin = string.split('>')[1]

consider following string: "nike store covent garden" suppose attempting detect brand matches following vector: brands <- c("adidas", "nike", "puma", "covent", "converse") below did resulting output: library(stringr) > brands[str_detect("nike store covent garden", brands)] [1] "covent" "nike" clearly brand here "nike", , know consistently located before location. there way can define rule in case detect multiple brands, select 1 appears earlier in string? note: in example above conveniently have brand name appear in beginning of string. have case string considering of form "0123 nike store covent garden" you can consider using str_locate instead of str_detect. : brands[which.min(str_locate("nike store covent garden", brands)[,1])]

i trying determine when canvas resized repaint it. context: canvas inserted in flex layout , height gets set flexbox model , changes depending on other layout elements content , size may dynamically vary (e.g., result of ajax request inserts texts in nearby span, causes canvas grow by, say, 10 pixels vertically). it seems resize event sent window — resize event not trick here, canvas may change size when window not. how can notified when canvas resized? if multiple parts of code change canvas size, must indeed refactor each scriptlet notify when changes canvas size. an easy way create resizing function scriptlet must use resize canvas. if function called, know scriptlet has resized canvas: function resizecanvas(canvas,w,h){ canvas.width=w; canvas.height=h; // canvas resizing flow point // respond resizing here. console.log('the canvas has been resized'); }

i have dataframe looks this: type unique_id val 0 x 1 11 1 x 2 12 2 y 1 20 3 y 2 30 the desired output is type unique_id val delta 0 x 1 11 9 1 x 2 12 18 2 y 1 20 0 3 y 2 30 0 namely, want match every x y has same unique_id (the id unique among x s, , separately unique among y s). then, want calculate difference of val each x , , respective y row. y s, value can 0. assuming unique_id in fact unique give type, can group on based on data filtered type y . gb = df[df.type == 'y'].groupby('unique_id').first() >>> gb type val unique_id 1 y 20 2 y 30 you join original dataframe: df = (df.set_index('unique_id') .join(gb, rsuffix='_')) >>> df type val type_ val_ unique_id 1 x 11 y 20 1

i have few wordpress plugins required updates. know there changes plugin files made myself , others overwritten updating plugins. don't know changes made since other people made of them. i updated plugins , pushed them separate branch. so, had master branch changes made plugins, , updated branch overwrote changes. merged both branches , there no conflicts. am right think changes made plugin files have been merged updates or lost of them? the git branches this: -----updated plugins---- / \ / \ ------master-----------------------merged branch---- yes, plugin have been merged. if changes others have overlapped changes made you, have had conflicts solve (which it's not case, said). since updated master branch changes made others, , merged yours, merged master branch have both changes in it. you can check commit logs see changes other people were. regards.
