is possible add new observable on top of observable chain merged? or whenever create new observable , have build new observable ? assume have merged observable like val trackable1: publishsubject[jsonobject] = publishsubject.create() val flushable: publishsubject[jsonobject] = publishsubject.create() val merged = flushable .mergedwith(trackable) .map(json -> { if (storage.size > 50) // send http request }); val trackable2: publishsubject[jsonobject] = publishsubject.create() // add trackable2 event source trackable1 // without rebuilding `merged` observable. thanks.

i work on team project using teensy , matlab, , avoid version differences (e.g 1 person loads teensy version a, , person using matlab has version b of code), i'd send version string on pairing. however, want version string sit in shared file between matlab code , teensy, , every time program loaded teensy, have included on compilation constant. sort of like: const string version = "<included file content>"; the matlab on part can read @ runtime. i thought of using file contents assignment variable name shared both teensy , matlab, prefer more elegant solution if such exists, 1 doesn't include executing code external file @ runtime. one way have simple setup so: version.inc: "1.0.0rc1"; main.cpp: const string version = #include "version.inc" ... note newline between = , #include in place keep compiler happy. also, if don't want include semicolon in .inc file, can this: main.cpp: const string versi...

my question similar getting sub-array existing array although little different notion important in case - can't use memory copying. let's have array x of 10000 elements, need array y contains 9000 elements x , starting x 's index 500. but don't want copy part of x new array y , don't want use array.copy, array.clone, system.block.copy, ienumerables etc. want y reference x - y[0] in fact x[500] , y[1] corresponds x[501] , ..., y[9000] x[9500] . thus, example changing value of x[100] @ same time change value of y[600] . how can achieve in c#? you wrap in object this: class view<t> { private t[] _array; private long _start; private long _length; public view(t[] array, long start, long length) { ... } public t this[long index] { { if (/*do bounds check here*/) { return _array[_start + index]; } } } } this won...

recently, upgraded android-sdk android m (api 22, mnc preview) . after this, every project reported errors when eclipse opened. the error said: "error executing aapt. please check aapt present @ ..\sdk\build-tools\23.0.0_rc1\aapt.exe" . after checking *.exe file, found "aapt.exe" of 23.0.0_rc1 @ ..\23.0.0_rc1\bin\aapt.exe not of 22.0.1 @ ..\22.0.1\aapt.exe . so, location of aapt.exe changed, eclipse can't realize that. so, did android on purpose or carelessly? how solve problem in case of no changing original file structure? i use eclipse android studio. so, want make sure android sdk ok first, eclipse, don't change structure of sdk any tips appreciated. in advance. p.s.: my os windows 7 , mac os x ; the version of adt plugin eclipse 23.0.6 , date now; also, there error reported popup window when eclipse starts: error: error parsing ...\sdk\system-images\android-22\android-wear\armeabi-v7a\devices.xml cvc-complex-type.2.4.d: fo...

i'm working on writing script break repeating-key xor (vigenère) cipher. this involves determining number (0 < n < maybe 50) splitting bytes object n smaller blocks, first block contains (from original object) indexes n, 2n, 3n, next 1 contains n+1, 2n+1, 3n+1... n+y, 2n+y, 3n+y y < n. if n = 3, bytes [0, 2, 5, 8 etc] should in 1 block, bytes [1,3,6,9] in next block, , bytes [2,4,7,10] in final block. i implement strings, don't know how make work bytes objects. searched , found , adapted code: blocks = [ciphertext[i:i+most_likely_keylength] in range(0, len(ciphertext)+1, most_likely_keylength)] transposedblocks = list(zip_longest(*blocks, fillvalue=0)) ##ciphertext bytes object resulting following line: ##ciphertext = base64.b64decode(open('q6.txt', 'r').read()) this returns list of tuples filled integers, , don't know how 'join' integers again they'll long binary objects before. (so can run nice crypto.util.strxor_c on e...

i given set of defined clusters , vectors belong in these clusters. wish find gaussian probabilities every point wrt each defined cluster. best way find density functions of defined clusters or gaussian mixture parameters each cluster? parameters of density functions computed through em algorithm given clusters , points. if have clusters, let mean , variance of each density function mean , variance of points in each cluster, , let mixing weight (number of points in cluster)/(total number of points).

i have formula answer following: if c6/2 less .5, e6 .5 otherwise answer c6/2. i go equivalent (but smaller) statement =if(c6<1,.5,c6/2) what you're doing has name it's called max function. =max(c6/2,.5) produce same result easier read.
