QUESTION
When I enable Global Method Security, I get 404/NotFound
when I call my endpoint that belongs to a class annotated with @Preauthorized
This is my configuration:
...ANSWER
Answered 2020-Oct-02 at 01:53I guess you got 404
because you have @PreAuthorize
and missing proxyTargetClass = true
for @EnableGlobalMethodSecurity
annotation. Spring loses your controller because it's a JDK proxy instead of CGLIB and doesn't have @RestController
anymore.
Try to replace it with:
QUESTION
I have been a C/C# developer for many years but haven't written any Alexa apps. I would like to write a skill to listen for baby babble (NOT WORDS) and respond in different ways. I would like my Alexa skill to keep the microphone ALWAYS on (similar to how "Alexa, Guard" works) because babies speak randomly.
Is there some sample code I can look at?
...ANSWER
Answered 2020-Feb-10 at 14:59You can't do this.
There is no way to keep the microphone open with a custom skill.
When you activate the skill "open my skill", Alexa starts talking and then, when she stops, you have only 8 + 8 seconds to speak, otherwise, the session will be closed.
So you have 8 seconds, then if you don't speak there is a re-prompt phrase asking you to tell something, and another 8 seconds where you can speak.
If you don't, the session will be closed.
There is a way to keep the session open more than 8 seconds (playing some mute music for example), but the problem remains because you can only speak after that "music" is finished.

QUESTION
I forked a great project here, and have just been having a mess around with it learning some go. My issue I can't figure out is some things about custom unmarshaling, if you see here you can see this unmarshals the Thing
struct which holds a Data interface{}
field that is then unmarshalled using the Kind string
field. This all works great except the nested situations. So the best thing is an example:
Just say you have Thing
struct that's kind is a listing
, thus the Thing.Data
this is unmarshalled to type listing
. Then listing
has 3 Children
of type link
that is held in the Children []Thing
field. These Children end up being of type map[string]interface {}
which is my issue. How can I have this unmarshall down through nested data? So that the Children.Data
is also unmarshalled. Is there a way to do this in go or will I have to write a big loop or recursion algorithm? Please let me know what you think or if I am looking at this situation all wrong. Thank you
UPDATE Here is a json sample
...ANSWER
Answered 2018-Feb-21 at 14:39In your case you needs to create a recursive function which will get the nested value of underlying interface{}
till last depth. There is no way we can get nested value from interface{}
with unknown underlying type. Here is an example of what you can do in your code
QUESTION
I am attempting to write a method that replaces every occurrence of a letter after the first as a "*" instead of the letter. Examples: "babble" yields "ba**le" "that" yields "tha*"
My code seems to be having an issue with the replace function while looping and I can't quite figure out why.
...ANSWER
Answered 2019-Sep-24 at 17:34The str.replace
method returns a copy of the original string with all occurrences of the given substring replaced with the given new string, so you can simply slice the input string from the second character and replace all occurrences of the first character with '*'
, and concatenate it after the first character of the orignal string:
QUESTION
I'm trying to write a function that takes a 2d list, finds the part of the list that has the highest value in its column, and returns that part of the list including the row and the column.
This is a homework problem that simulates Scrabble. Essentially, you give the function a list of characters and it returns a list of the best word you could make out of characters based on that word's value and the value itself.
There's some global variables in this problem: scrabbleScores (a list of that characters and their values) and Dictionary (all the words you could possibly make).
For example, if you gave it the list, ['a', 's', 'm', 't', 'p'], it would first call another function that returns all of the words you could make from that list and their values, then it would use that list and return a list with the best word and its value.
So, I already have a function that I've been working on, but whenever I run it my IDE gives me a "int object is not subscriptable" error:
...ANSWER
Answered 2019-Sep-15 at 05:14Code is complicated but I found few mistakes which resolved problem with error.
bestWordHelper()
needs 2D list but problem is []
in some places and +
between list's elements so sometimes it creates 1D list instead of 2D list and then it can't get second dimention when you use L[0][1]
- and finally you get integer[0]
instead of list[0]
so you get your error message "int object is not subscriptable"
First: you forgot [1]

QUESTION
I am trying to learn to record X11 windows' contents to do game screencasts for Youtube. This should be a fairly trivial task, but it already ate a full evening. Now I have learned a bit about muxing and queueing (using gst-launch
), but the problem remains: When I mux an audio and video into an avi, video plays several times faster than audio in the resultant file. This means that video ends soon and comes to still, while audio continues to babble in the background.
This is my filter chain that causes the issue:
...ANSWER
Answered 2019-May-28 at 09:10gst-launch-1.0 ximagesrc xid=$XID ! video/x-raw,framerate=30/1 ! queue ! videoconvert ! videorate ! queue ! x264enc ! queue ! avimux name=mux ! queue ! filesink location=out.avi pulsesrc device=$DEV ! queue ! audioconvert ! queue ! lamemp3enc bitrate=192 ! queue ! mux.
The above pipeline should play the audio video at proper speed.
I would also appreciate if you correct me on the usage of ! queue !. Where is it needed? In the current setup I almost never get warnings that samples were dropped.
queue are just buffers, these need to be used in places where one element is slower and one is faster, so for example video generating (ximagesrc) is much faster compared with x264enc (software encoding), so you would add a queue in between them so as to buffers aren’t dropped.
gst-launch-1.0 ximagesrc ! video/x-raw,framerate=30/1 ! queue ! videoconvert ! queue ! x264enc key-int-max=5 ! queue ! mp4mux name=mux reserved-bytes-per-sec=100 reserved-max-duration=20184000000000 reserved-moov-update-period=100000000 ! queue ! filesink location=out.mp4 audiotestsrc ! queue ! audioconvert ! queue ! lamemp3enc bitrate=192 ! queue ! mux.
The above pipeline would create a mp4 file mp4mux, but the moov atom will be at end itself also note make sure you change mp4mux properties as per your need.
QUESTION
I have txt
file and want to parse content to Json
format.
My code is something like:
...ANSWER
Answered 2019-Jan-03 at 15:07Check your data for lines that are empty ... you got empty lines in it (maybe the last line has got a \n at its end?) resulting in raise JSONDecodeError("Expecting value", s, err.value) from None
.
This fixes that error:
QUESTION
#usr/bin/python 3.6.1
import sys
def fix_start(s):
a = s[0]
i=1
for i in s:
if a in s :
print("found")
s=s.replace(a,'*')
else: print (" not found")
return (s)
def main():
c = fix_start(sys.argv[1])
print (c)
if __name__=='__main__':
main()
...ANSWER
Answered 2018-Aug-07 at 11:59In python strings are iterables. So, your line for i in s
will run n times, one for every letter in the string, and will print "not found". The first time the loop runs, it replaces a
with*
. So, for all subsequent runs, it will print "not found".
