a few questions: suppose train pio system bunch of events, find out events wrong reason, , want system ignore or delete these events next time train it. how can without deleting entire database app? the events flowing pio server add billions. have regularly delete old events system, , if so, how? run queries directly against hbase or there special pio commands that? in installation process saw pio uses both hbase , elastic search. store in elastic search? code samples helpful. thanks. i assume ask universal template. you can change engine.json , remove event types. ignored. see - eventwindow in here hbase used save events data , elasticsearch used save metadata of items. can see in configuration file pio-env.sh please note universal template version (0.3.0) requires predicitionio actionml fork version 0.9.6.

i created messages extension in xcode 8 using appropriate template, seems working fine , when run extension, it's installed in messages app , can use without issues. my problem wanted create actual app associated extension (so user able search extension through messages store or install actual app through app store). gave matching bundle identifier (my extension com.xxx.testmessage.messagesextension, app set com.xxx.testmessage), when run app, doesn't install extension. is possible that? , if so, missing? in xcode8, open existing app. need add new target app (file->new->target->ios->sticker pack extension (or imessage extension if want custom messages experience)). create folder visible in project navigator. name of folder depends on name gave extension. in folder find stickers.xcassets can drop stickers.

i'm blocked because conditional evaluating both side of statement: =iif(isnothing(fields!canceldate.value), nothing, fields!canceldate.value.tolocaltime()) i'd have empty field when canceldate has no value because of tolocaltime(), breaks. is there came across this? you can use local time conversion on conditional statement so: =iif(isnothing(fields!canceldate.value), nothing, cdate(iif(isnothing(fields!canceldate.value), nothing, fields!canceldate.value)).tolocaltime()) this simplified, works.

i made custom type, called run, , 1 of values called runmoa. stores string, 12-digit number. have array of these runs, each different moa. have sheet has column of possible moas, , i'm trying loop through array of runs , row number of run's respective moa (for finding other data in sheet). strangely, working bunch of moas, not specific ones. did playing around, , seems error caused rounding or something. example, these moas being found in column: 200630031111, 200630021593, 200630021593, but these ones aren't: 200000000443, 200000000603, 200000000444. here's code loops through values (numruns length of runs array): dim integer = 0 numruns - 1 getrun i, n, schedule, skus next here's line that's supposed store row number in variable: row = application.worksheetfunction.match(val(runs(i).runmoa), worksheets("sheet1").range(cells(2, 1), cells(n, 1))) - 1 does function have problem when numbers big? it's giving me trouble whe...

i'm new in python , in oo programming, don't know if following question makes sense (...but think it's nice way learn): i'm trying have 2 classes. 1 generates data (call datagen() ) , able process data , give me statistics (call stats() ). want put both in different py files keep cleaner , can add methods stats.py without touching datagen.py. this: in datagen.py class datagen(object): def __init__(self, number_of_samples, arg2): self.x = np.zeros([number_of_samples,1]) # etc.. def samples(self): # sampling , save in self.x in stats.py class stats(object): def __init__(self, something): # here initialize # etc.. def mean(self): # calculate mean using datagen.x now, , here comes part lost. want stats() work on data belonging instance of datagen() , don't know how link data contained in datagen.x stats , can use data every time sample datagen.samples() . i tried construct inst...

is there referred method of calling c-code python component? porting redhawk csh script calls c-code programs (with "main" entry points , argument lists). prefer implement csh script python component, call c-code programs. couple of notes: i'm familiar doing in swig in gnu radio. i acknowledge bigger issue of rearchitecting entire system connected sdr components, fundamental c-from-python issue remains. this interesting question. have access source code traditional "main" application? statement swig suggest do. if do, best approach may use shared library pattern discussed in section 4.9 of redhawk manual. problem either swig or shared library approach require restructuring of legacy c application shared library. if legacy form of batch processor takes in commands , data , pushes out results, may best using fork/exec paradigm. i'm making huge assumptions here, if legacy app puts output on stdout, can attach stdout pipe read in compo...
