ios - How to customize GKGameSession message notifications? -

-
i can't figure out how customize gkgamesession message notifications, if it's possible. default notifications include snippet of text supply when sending message, result awkwardly worded, uses game center icon instead of app's icon, , plays annoying little jingle. ideally, i'd modify gkgamesession message notifications notification content extension, when created 1 in app, not invoked. any ideas? thanks.

php - validation value having two possible types -

-
how validate request value when should string or array both valid? 'val' => 'bail|required|string' 'val' => 'bail|required|array' what the validation expression? i don't think there way achieve using validation rules out of box. need use custom validation rules achieve this: in appserviceprovider 's boot method, add in public function boot() { validator::extend('string_or_array', function ($attribute, $value, $parameters, $validator) { return is_string($value) || is_array($value); }); } then can start using it: 'val' => 'bail|required|string_or_array' optionally can set custom validation error messages, or using custom validation class achieve it. check out doc link above more information.

python - Implementation of methods in Tensorflow -

-
i'm trying activate neural network using tensorflow tools. of way there 1 method trying implement (so can use on data) many problems. method is from tensorflow.examples.tutorials.mnist import input_data mnist = input_data.read_data_sets(...) ... x, y = mnist.train.next_batch(batch_size) there nice explanation using tensorflow can't find how method implemented. every iteration need take different part data (and think method return data + y). attached code case: file = open('stub.csv') reader = csv.reader(file) temp = list(reader) del temp[0] ... temp in range(int(len(data) / batchsize)): ex, ey = takenextbatch(i) # takes 500 examples += 1 temp, cos = sess.run([optimizer, cost], feed_dict= {x:ex, y:ey}) # start session optimize cost function epochloss += cos when "takenextbatch(i)" method tried write.

Set variables in parallel in bash -

-
here's example program: #!/bin/bash x in {1..5} output[$x]=$(echo $x) & done wait x in {1..5} echo ${output[$x]} done i expect run , print out values assigned each member of output array, prints nothing. removing & correctly assigns variables. must use different syntax achieve in parallel? this output[$x]=$(echo $x) & puts whole assignment in background task (sub-process) , that's why you're not seeing result, since it's not propogated parent process. you can use wait wait subprocesses , returning results (other status codes) going difficult. perhaps can write intermediate results file, , collect results after processes have finished ? (not nice, appreciate)
