What is the maximum number of events per page returned for calendarview endpoint in Office365 Calendar REST Api? -

as suggested in answer question: office365 rest v1.0 api calendar not return recurrences i using calendarview endpoint. here documentation it: https://msdn.microsoft.com/office/office365/api/calendar-rest-operations#eventoperationsgetevents in documentation following link odata query parameters discuss paging of response: https://msdn.microsoft.com/office/office365/api/complex-types-for-mail-contacts-calendar#useodataqueryparameterspageresults however, mentions maximum number of entries per page returned messages or childfolders endpoints, not number of entries per page returned calendarview endpoint. doubt 10 or 50, few events typical calendarview call. can point me documentation outlines value? update: sorry, didn't understand question right. max # of items returned in page 10 if $top isn't specified query parameter, value of $top if $ top specified , $top<=50, , 50 if $top specified query parameter $top>=50 . example: https://outlook.o

i found out how current date , time variables (right?) in c# this thread code datetime = datetime.now; string date = now.getdatetimeformats('d')[0]; string time = now.getdatetimeformats('t')[0]; however i'm not sure first line does. after thinking suppose calls current date , time data computer , applies/tells program. by way, i'm noob @ programming , new c#. the first line datetime = datetime.now; takes current time, , stores in variable. reason it's done make sure subsequent calls of getdatetimeformats performed on variable representing same time. if call datetime.now several times, may different time each time make call. for example, if string date = datetime.now.getdatetimeformats('d')[0]; string time = datetime.now.getdatetimeformats('t')[0]; very close midnight, date , time portions may belong different dates.

javascript - Testing XHR with Jest -

-
i have simple test case: describe ('request', function () { ('should perform xhr "get" request', function (done) { var xhr = new xmlhttprequest; xhr.open('get', 'http://google.com', true); xhr.send(); }); }); the point is: when jest in terminal, seems it's not requesting http://google.com . think happening because jest uses jsdom under hood , haven't capability reproduce http request out of browser itself. suggestions? note: errors appearing, test passing, request isn't being made. there're number of problems: in code example don't create instance of xmlhttprequest. should this: var xhr = new xmlhttprequest() making real requests in tests bad idea. if module depends on data remote server should mock xmlhttpsrequest or use "fake server" (e.g. sinon ). recommend don't make real requests in tests.

do have use 5 different image sizes on android apps or there other way change resolution of image using bitmap or else? i'm copying 5 different sizes seems there should better way programmatically. it's best load smaller resource smaller screen density , larger resource larger density due how memory larger bitmap has allocate. although need bitmap scale size manage several screen sizes, call bitmap.createscaledbitmap(bitmap src, int dstwidth, int dstheight, boolean filter) another way if drawing bitmap ondraw(), can use drawbitmap() method passing destination rect/rectf image automatically fill.

Working with binary in Python, Splitting numbers -

i have module takes 2 x 8bit numbers in decimal format, specific structure each number must start same 4 bits = 0011 followed varible 8 bits followed 4 bits ignored set 0000 so caculate 16bit number simple enough the varible number * 16 shift 4 bits left, , adding 12288 = 0011|000000000000 give me desired result. so if input number 19 example 19 x 16 + 12288 = 12592 = 0011000100110000 the next step split in 2 x 8 bit numbers 00110001 | 00110000 = 49, 48 how in python can go 12592 49,48 efficiently. never worked in binary in script bit new. cheers to first 8 bits, shift right 8 bits. 0011000100110000 >> 8 == 00110001 to last 8 bits, mask 0b11111111 , i.e. 255 . 0011000100110000 & 0000000011111111 ------------------- 0000000000110000 code example: in [1]: n = int("0011000100110000", 2) in [2]: n out[2]: 12592 in [8]: n >> 8, n & 255 out[8]: (49, 48)

list - Python recursive no 'in' work around -

-
so recursive function in list , see if item repeated in list already. ex. l = [1,2,3,4,3] return true. i've completed im not allowed use 'in' function dont know work around. edit: built in functions allowed use len , , index , splice operators. def has_repeats(l): if l == []: return false elif l[0] in l[1:]: return true else: return has_repeats(l[1:]) return false you may consider using recursion compare list in reversed order indexes same, since index @ default returns first occurrence, this: def has_repeats(l): if len(l) <= 1: return false if l.index(l[-1]) != len(l) - 1: return true return has_repeats(l[:-1]) usage: has_repeats([1, 2, 3, 4, 3]) true has_repeats([1, 2, 3, 4, 0]) false so check index of last item len(l) - 1 same l.index should return first occurrence, if don't match, there duplicate before last item, , recursively.

What is the correct way (if any) to use Python 2 and 3 libraries in the same program? -

-
i wish write python script needs task 'a' , task 'b'. luckily there existing python modules both tasks, unfortunately library can task 'a' python 2 only, , library can task 'b' python 3 only. in case libraries small , permissively-licensed enough convert them both python 3 without difficulty. i'm wondering "right" thing in situation - there special way in module written in python 2 can imported directly python 3 program, example? the "right" way translate py2-only module py3 , offer translation upstream pull request (or equivalent approach non-git upstream repos). seriously. horrible hacks make py2 , py3 packages work not worth effort.
