kandi X-RAY | linked Summary
Linked allows you to write down your thoughts and ideas to link them with days. The app was originally created as a weekend project for my colleagues at work. We needed an app to offload our brain and write down things that we may need for our daily meetings or other scrum events, things that simply did not fit inside a ticket. You can download linked here for free!. Make sure to follow @uselinked on twitter to get the latest news about the project or feel free to check github discussions.

QUESTION
I have a WPF app, linked to a SQL-server. I am using the MVVM-light package (I do actually have Prism.Core installed, but I'm not sure if I'm using it or not.... new to MVVM).
There's a DataGrid
, bound to an ObservableCollection
.
I have been trying to implement the PropertyChangedEventHandler
, but I can't seem to get it to work.
I have a Delete button bound, and I am able to remove rows, but when I re-open the form, the changes does not carry over.
I tried to change the binding-mode for the DataGrid
from OneWay
to TwoWay
. With OneWay
, the changes does not carry over when I re-open the form. With TwoWay
, I get this error message when opening the child form (which contains the DataGrid
):
System.InvalidOperationException: 'A TwoWay or OneWayToSource binding cannot work on the read->only property 'licenseHolders' of type 'Ridel.Hub.ViewModel.LicenseHoldersViewModel'.'
So, If I then add a set;
to my public ObservableCollection licenseHolders { get; }
,
the program runs, but the previous problem persists, like it did when there was a OneWay
mode configuration on the DataGrid
.
What do I need to do to get this to work without communicating directly with the Sql-server
, which would defy the whole point of using this methodology in the first place?
ANSWER
Answered 2021-Jun-15 at 13:26You are confusing topics. The VM needs InotifyPropertyChanged
events, which you have but are not using, to notify the Xaml in the front-end that a VMs property has changed and to bind to the new data reference.
This is needed for List
s or ObservableCollection
s. Once that is done, the ObservableCollection
will then send notifications on changes to the list as items are added or removed.
Because you miss the first step:

QUESTION
I am writing a program in C language using gtk3 library. I want it to be able to receive a h264 video stream from a certain IP address (localhost) and UDP/RTP PORT (5000).
In order to do it, I am using gstreamer to both stream and receive the video.
I managed to stream the video using the following pipeline :
send.sh :
gst-launch-1.0 filesrc location=sample-mp4-file.mp4 ! decodebin ! x264enc ! 'video/x-h264, stream-format=(string)byte-stream' ! h264parse ! rtph264p
I managed to display the video in a new window using the following pipeline :
receive.sh :
gst-launch-1.0 udpsrc port=5000 caps="application/x-rtp,encoding-name=H264" ! rtph264depay ! decodebin ! videoconvert ! autovideosink
At this point, everything works fine. But now I want to receive the stream and display it inside my C/GTK program. I am using the following code (found on internet and adapted to make it compile) :

QUESTION
I am writing code to answer the following LeetCode question:
Given the head of a linked list and an integer
Example 1 ...val
, remove all the nodes of the linked list that hasNode.val == val
, and return the new head
ANSWER
Answered 2021-Jun-15 at 10:52Some issues in your code (as it was first posted):
return skipper(prev,curr)
is going to exit the loop, but there might be more nodes to be removed further down the list.skipper
only takes care of a sub sequence consisting of the same value, but it will not look beyond that. The list is not necessarily sorted, so the occurrences of the value are not necessarily grouped together.Be aware that the variable
prev
inskipper
is not the same variable as the other, outerprev
. So the assignmentprev=curr
inskipper
is quite uselessUnless the list starts with the searched value,
dummy.next
will always remainNone
, which is what the function returns. You should initialisedummy
so it links tohead
as its next node. In your updated code you took care of this, but it is done in an obscure way (in theelse
part).dummy
should just be initialised as the head of the whole list, so it is like any other node.
In your updated code, there some other problems as well:
while prev.next:
risks to be an infinite loop, because it continues whileprev
is not the very last node, but it also doesn't move forward in that list if its value is not equal to the searched value.
I would suggest doing this without the skipper
function. Your main loop can just deal with the cases where current.val == val
, one by one.
Here is the corrected code:
QUESTION
When setRows()
run on an existing GridItem
, the generated Form GridItem
elements are fine, but the columns in the linked Sheet are reproduced in the next columns. The new columns are duplicates, but with a hidden property that shows that they belong to the Form (so we cannot delete the new columns). What is this property? The old columns are no more belong to the Form. The old columns may have existing values or previous Form responses.
How to prevent this?
The FormApp
should handles the sheet Ranges properly, by looking for the existing columns and just adds the real new columns with new array of strings.
How did the Google Forms UI handle this: When we use the Forms UI, we can easily add new rows in GridItem, and the link Sheet will be updated without duplicated columns.
Here is the Form to test, and please create a new linked response-Sheet before running the code:
Copy Sample Form with GAS code
Here is the GAS code:
...ANSWER
Answered 2021-Jun-15 at 09:35The process of manually editing a grid in a form with a linked sheet is as follows:
- You click the input box for the item.
- You update the text.
- The sheet will automatically replace the title of the corresponding column.
However, with Apps Script. The only process available to change a title, is to use the method .setRows
or .setColumns
. This behaves very differently from the UI. Esentially, it replaces the rows, and so, the linked sheet will generate new columns so as to preserve the previous answers.
It creates new columns because it has no way to know which new title corresponds to the old one.
For example, if you had some rows:
- A
- B
- C
When you get this from Apps Script, you have to first getRows()
QUESTION
I am working on a CI config to push to multiple projects in remote server.
So I temporary push them on github public project, which have a config.cfg
file contains these line below.
ANSWER
Answered 2021-Jun-15 at 09:31This is extreme weird behaviour, and I dont really think github and slack are linked together somehow that magically remove APP as soon as its Token got exposed.
They are, though: https://docs.github.com/en/code-security/secret-security/about-secret-scanning
Secret scanning is a mechanism to do just that, detect accidentally leaked secrets in GitHub and report them to the affected service. There are 40+ partners already participating in this, including Slack.
GitHub scans repositories for known types of secrets, to prevent fraudulent use of secrets that were committed accidentally.
Secret scanning is automatically enabled on public repositories. When you push to a public repository, GitHub scans the content of the commits for secrets. If you switch a private repository to public, GitHub scans the entire repository for secrets.
Probably intentionally publishing a live token to a public GitHub repo is a not the right approach, I'd recommend using a private repo instead.

This is an extension of the below question.
I have a collection where each document contains 2 arrays as below.
...ANSWER
Answered 2021-Jun-15 at 09:16This may not be as generic but will push you in the right direction. Consider using the operators $mergeObjects
to merge the filtered document from the priv_users
array with the document in users.
Filtering takes the $substr
of the priv_users
name field and compares it with the users
name field. The resulting pipeline will be as follows

QUESTION
TL;DR: Interested in knowing if it's possible to use Abstract Base Classes as a mixin in the way I'd like to, or if my approach is fundamentally misguided.
I have a Flask project I've been working on. As part of my project, I've implemented a "RememberingDict" class. It's a simple subclass of dict, with a handful of extra features tacked on: it remembers its creation time, it knows how to pickle/save itself to a disk, and it knows how to open/unpickle itself from a disk:
...ANSWER
Answered 2021-Jun-15 at 03:43You can get around the problems of subclassing dict
by subclassing collections.UserDict
instead. As the docs say:
Class that simulates a dictionary. The instance’s contents are kept in a regular dictionary, which is accessible via the data attribute of UserDict instances. If initialdata is provided, data is initialized with its contents; note that a reference to initialdata will not be kept, allowing it be used for other purposes.
Essentially, it's a thin regular-class wrapper around a dict
. You should be able to use it with multiple inheritance as an abstract base class, as you do with AbstractRememberingDict
.
QUESTION
I'm running gitlab-ce on-prem with min.io as a local S3 service. CI/CD caching is working, and basic connectivity with the S3-compatible minio is good. (Versions: gitlab-ce:13.9.2-ce.0
, gitlab-runner:v13.9.0
, and minio/minio:latest
currently c253244b6fb0
.)
Is there additional configuration to differentiate between job-artifacts and pipeline-artifacts and storing them in on-prem S3-compatible object storage?
In my test repo, the "build" stage builds a sparse R package. When I was using local in-gitlab job artifacts, it succeeds and moves on to the "test" and "deploy" stages, no problems. (And that works with S3-stored cache, though that configuration is solely within gitlab-runner
.) Now that I've configured minio as a local S3-compatible object storage for artifacts, though, it fails.
ANSWER
Answered 2021-Jun-14 at 18:30The answer is to bypass the empty-string test; the underlying protocol does not support region-less configuration, nor is there a configuration option to support it.
The trick is able to work because the use of 'endpoint'
causes the 'region'
to be ignored. With that, setting the region to something and forcing the endpoint allows it to work:
