I have created an app that uses a button to open a new screen that plays a video using kivy VideoPlayer. The app works fine on windows but when I run on Android, the app crashes when trying to open the screen where the video will be playing. Below is the logcat output right after the the crash. I could use help interpreting the log to determine what might be causing the crash.

let df =

(("N3",100,3), "C1", 4.0); (("N4",100,4), "C1", -6.4);

|> Frame.ofValues
I'd like to be able to group the columns by the second item in the Row Key tuple - so by 100 and 200 and then change the frame to Frame<(string*int),(int*int)>
It seems like I have to use Frame.Transpose and then Frame.groupRowsUsing to group the columns but I'm at a loss of how to get the 100/200 in the selector function.
Output should look like:
(100,C1) (100,C2) (200,C1) (200,C2)
N1 1 -> 1 1 1 1
N2 2 -> 3.1 5.1 1.1 7.1
N3 3 -> 4 4 4 4
N4 4 -> -6.4 -8.4 -9.4 -2.4
It was not clear to me if the intent was to keep the column keys as they are and change the row values to tuples or if the columns were supposed to be tuples and the values to remain as floats.
Assuming the first option:
//adding a helper function to the module: transforms row data and replace a given columns
module Frame =
let mapiReplaceCol col f frame = frame |> Frame.replaceCol col (Frame.mapRows f frame)
(df,df.ColumnKeys)
||> Seq.fold (fun acc elem ->
acc |> Frame.mapiReplaceCol elem (fun (_,k,_) row -> k,row.GetAs<float>(elem)))
|> Frame.mapRowKeys (fun (a,_,c) -> a,c)
(*output:
C1 C2
N1 100 1 -> (100, 1) (100, 1)
N2 100 2 -> (100, 3.1) (100, 5.1)
N3 100 3 -> (100, 4) (100, 4)
N4 100 4 -> (100, -6.4) (100, -8.4)
N1 200 5 -> (200, 1) (200, 1)
N2 200 6 -> (200, 1.1) (200, 7.1)
N3 200 7 -> (200, 4) (200, 4)
N4 200 8 -> (200, -9.4) (200, -2.4)
*)
Assuming the second option:
Step 1: descontructing the Frame to (row * col * value) and reconstructing
let step1 =
df |> Frame.mapRows (fun (a,b,c) row ->
df.ColumnKeys |> Seq.map (fun col ->(a,c),(b,col),row.GetAs<float>(col)))
|> Series.values |> Seq.concat |> Frame.ofValues
(*
output:
100 200
C1 C2 C1 C2
N1 1 -> 1 1 <missing> <missing>
5 -> <missing> <missing> 1 1
N2 2 -> 3,1 5,1 <missing> <missing>
6 -> <missing> <missing> 1,1 7,1
N3 3 -> 4 4 <missing> <missing>
7 -> <missing> <missing> 4 4
N4 4 -> -6,4 -8,4 <missing> <missing>
8 -> <missing> <missing> -9,4 -2,4
*)
Step 2: reducing levels
let step2 = step1 |> Frame.reduceLevel fst (fun (a : float) b -> a + b)
(*
output:
100 200
C1 C2 C1 C2
N1 -> 1 1 1 1
N2 -> 3,1 5,1 1,1 7,1
N3 -> 4 4 4 4
N4 -> -6,4 -8,4 -9,4 -2,4
*)
Step 3 (optional): reacreating the tuples in the index
let step3 = step2 |> Frame.mapRowKeys (fun k -> k,k.Replace("N","") |> int)
(*
output:
100 200
C1 C2 C1 C2
N1 1 -> 1 1 1 1
N2 2 -> 3,1 5,1 1,1 7,1
N3 3 -> 4 4 4 4
N4 4 -> -6,4 -8,4 -9,4 -2,4
*)
Basically, we reconstructed the frame from scratch. Maybe a better approach would be to change how the original frame is being constructed instead of doing all this.

While there are program version differences between the setups (in CentOS 7 blktrace is version 1.0.5 and the kernel is based off 3.10 whereas in Ubuntu 16.04 blktrace is version 1.1.0 and the kernel may be between 4.4 - 4.10) the real point may be down to what was asked (but unfortunately went unanswered) in one of the comments:
what [I/O] scheduler was in use
If we look at one of your m lines:
8,0 3 0 0.000015209 0 m N cfq24714SN /user.slice insert_request
we can see that it is a textual message (hence the m) and that it likely came from the CFQ I/O scheduler (hence the cfq prefix on the message itself). If the I/O scheduler being used for the /dev/sdb device on the CentOS 7 setup was not CFQ (e.g. because the noop I/O scheduler was being used) then we cannot expect similar messages to be present.
So bringing this back to the title of the question:
blkparse how to show IO Scheduler message
If an I/O scheduler wants to it can send free form blktrace text (e.g. see block/cfq-iosched.c which has calls to blk_add_trace_msg() in it) but not all I/O schedulers do (e.g. see block/noop-iosched.c which doesn't even include the linux/blktrace_api.h header). By default blkparse will show all messages present unless you use the -M option to suppress them.
GNU DC displays the stack vertically, (f displays the stack)
1 2 3 4
f # to display the stack
4
3
2
1
Is there a way to change this to be more like FORTH? While GNU FORTH displays the stack horizontally, (.s displays the stack)
1 2 3 4 ok
.s <4> 1 2 3 4 ok
You can create custom function in ~/.dcrc which is read each time dc start.
cat ~/.dcrc
[
# if the stack is empty
[ 2 + [stack empty] p 0 :- Q ]s-
z d 0 =- 0 :-
# keep the stack in indexed array -
[ z :- z 0 <- ]s-
l-x
# restore the stack
[ 0 ;- 1 + d ;- ;- r d ;- 1 + r :- 0 ;- d 1 + ;- r !<- ]s-
1 0 ;- 1 + :-
l-x
# displays the stack horizontally
[ 0 ;- d 1 + d ;- ;- n [ ] n d d ;- 1 + r :- ;- !>- ]s-
1 0 ;- 1 + :- l-x [ ok] p 0 :-
]s-
You call it this way :
echo '7 16 8 9' | dc -f - -e 'l-x f'
and you get :
7 16 8 9 ok
9
8
16
7

I have users and products which the user has purchased, and there seems to be no ratings for the products given by users. Blow is the sample data
DATA :

A 111, 333, 444

C 555, 111, 333
D 222,333, 333,333
E 111,333,444,555
F 222,555,111
Can we find similar customers based on above data. Am trying to use 1 for product purchase and 0 if not like below.

B 0 0 1 1 1
C 1 0 1 0 1

Using the above matrix, how do I find similar customers. expecting an output in the below format.
user Id similar customers

from sklearn.feature_extraction.text import TfidfVectorizer, CountVectorizer

Good Afternoon,
I am attempting to create a socket program which connects to Apple Push Notification Service (APNS) and sends a push notification.
I am wondering if anyone can help me with the actual writing of the APNS notification.
Below you can see my program which I used Scott Klement's Socket Programming tutorial to help me with.
The code that is probably relevant to all of this is marked as 'APNS Notification Format Begin', 'Initialize', and 'Formulate message to APNS' in comments although I included the entire program for reference.
I have read the Provider Requirements on Apple's site Provider Requirements but I am still having trouble getting everything working.
My program compiles and when I debug it / run through the steps I get past establishing an actual connection so I 'think' that this part is OK.
What I am hoping is to get back an error identifier from Apple in the variable errid within the item3 data structure. Apple states in the Provider Requirements that they return a status code if there is an error but that particular variable remains at 1077952576
There are also quite a few other things that I am unsure of
1) I have been given the device token as a Base64 string. The string is 40 some odd characters long but from what I understand, Apple states device token length should be 32 bytes. In RPGLE doesn't 1 character represent 1 byte? If that's the case then I couldn't just declare my variable token as
D token 32a
because it would get cut off?
2) Is anyone able to tell me what I am doing wrong when it comes back to receiving a proper error identifier from Apple in my variable errid?
Any help would be greatly appreciated

This isn't even close, you're using characters instead of binary data.
cmd = '2' + 3 + 1 + 64 + 'x' + 2 + 50 + '{"aps":{"alert":"You have mail"}} +
3 + 3 + '001'
This should be closer; but it is off the top of my head and completely untested...

I've not done raw sockets on the IBM i before, you may have to convert EBCDIC to ASCII. I don't think you'll need to worry about little vs. big endian.
RPG is probably not the best choice for this, Java might be a better choice given the existence of projects like Java PNS
Stackoverflow doesn't have a whole lot of RPG / IBM i traffic. You may get a better response on the following:
