            The unauthenticated git protocol on port 9418 is no longer supported
            Asked 2022-Mar-27 at 13:23

            I have been using github actions for quite sometime but today my deployments started failing. Below is the error from github action logs

            First, this error message is indeed expected on Jan. 11th, 2022.
            See "Improving Git protocol security on GitHub".

            January 11, 2022 Final brownout.

            This is the full brownout period where we’ll temporarily stop accepting the deprecated key and signature types, ciphers, and MACs, and the unencrypted Git protocol.
            This will help clients discover any lingering use of older keys or old URLs.

            Second, check your package.json dependencies for any git:// URL, as in this example, fixed in this PR.

            As noted by Jörg W Mittag:

            There was a 4-month warning.
            The entire Internet has been moving away from unauthenticated, unencrypted protocols for a decade, it's not like this is a huge surprise.

            Personally, I consider it less an "issue" and more "detecting unmaintained dependencies".

            Plus, this is still only the brownout period, so the protocol will only be disabled for a short period of time, allowing developers to discover the problem.

            The permanent shutdown is not until March 15th.

            For GitHub Actions:

            As in actions/checkout issue 14, you can add as a first step:



            setValue not workin on dependant Earth Engine ui.Select widget
            Asked 2022-Mar-24 at 15:19

            I am working on an Earth Engine application where I have 2 widgets of type ui.Select that are dependent on each other (bidirectionally dependent). That is, when I make a change in one of them, it changes the list in the other and vice versa.

            The behavor is correct, except that when I want to reselect the option that was before the change, it does not work. Due to the items generator script that populate the widgets is allways sure that the previous selection is in the new (modified) items list.

            Here are the two widgets implementations

            The onChange function of your button #2 is resetting your button #1 every time. You only need to uncomment lines 209-216 of your code, so the onChange function of your variable var select_date_end looks like this:



            Copy/Paste Data Log Based on a Condition
            Asked 2022-Mar-18 at 17:16

            The following code copies a row of data from a Dashboard to a Data_Log as you repeatedly click the Start button. I am trying to add a condition that each time a Yes appears in column D of the Time Log copy the data from the Dashboard to the Data_Log and only click the Start button once to initiate as it should run continuously until you hit the Stop button.

            The problem is I cannot copy the data when the Yes condition appears on the Time_Log.

            Logic -> Condition of Yes appears on the Time_Log -> copy from Dashboard -> paste to Data_Log -> continues to copy/paste as the Yes increments on the Time_Log with time moving forward. Thank you for your help.



            Answered 2022-Mar-18 at 17:16

            lastRow is typed as a Range instead of a Numeric data type. wsTime_Log.Cells(Rows.Count) refers to column 1 which is empty.



            Android clear backstack after reselecting Bottom Navigation tab
            Asked 2022-Feb-23 at 18:37

            Using the newest Navigation Component with the BottomNavigationView, the NavController now saves and restores the states of tabs by default:

            As part of this change, the NavigationUI methods of onNavDestinationSelected(), BottomNavigationView.setupWithNavController() and NavigationView.setupWithNavController() now automatically save and restore the state of popped destinations, enabling support for multiple back stacks without any code changes. When using Navigation with Fragments, this is the recommended way to integrate with multiple back stacks.

            This is great! Now switching tabs gives you the last viewed stack.

            But, if the user reselects a tab, say they've gone Home -> Detail Page A -> Detail Page B, then they select the Home tab expecting to go back to the default view, they still see Detail Page B.

            It seems like part of the discussion was to handle the "reselecting a tab" behavior as mentioned in the issue tracker, but I can't figure out the recommended way for implementing this.

            All that's included in the NavigationAdvancedSample is:



            Answered 2021-Aug-14 at 00:04

            BottomNavigationView has its own method for handling reselection via setOnItemReselectedListener() (or, when using an earlier version of the Material Design Library, the now deprecated setOnNavigationItemReselectedListener()).

            bottomNavigationView.setupWithNavController does not set this listener (as there is no Material specification for exactly what reselecting a tab should do), so you need to set it yourself:



            Flutter - Dispose a variable
            Asked 2022-Feb-18 at 05:29

            I have a page to create posts. I'm using image_picker package to get images and there's a provider that gets the images to the post creation page. There's a variable selectedImagesList that stores the list of picked images to be shown after they're picked by user.



            Answered 2022-Feb-18 at 05:29

            You're not using selectedImagesList defined in the state, instead, you're using selectedImagesList defined in PostNotifier class. so inside dispose method you should clear selectedImagesList defined in PostNotifier class.

            Asked 2022-Feb-09 at 06:34

            I'm only seeing mention of changes in babelrc etc. online for this message. I've tried to remove the dependency that gives me this error and it appears that then next dependency evaluated returns the same message.

            The error is coming from any/all of my node_modules folder and the code is correct. I'm guessing something has changed w/ versions of something in my dev dependencies but not sure how to track it down...

            Disable checkbox for item that is not defaultChecked
            Asked 2022-Jan-18 at 18:43

            I have two checkbox items. One of them will be default selected upon entry into the page, by props. Depending on which item is selected on default, the other checkbox item should be disabled upon entry into the page.

            Also, the user can deselect the default checked item, in which case, both checkboxes become enabled for selection. When the user then selects one of the two options, the non-selected option will become disabled again.

            What works: When I deselect the default option and reselect one of the two checkboxes, the disabled behavior works correctly (in that the non-selected option becomes disabled).

            What does not work and need to find a fix for: When I enter the page, the option that is NOT selected by default needs to be disabled. I need to figure out how to disable the non-selected option upon entry into the page.

            At the moment you are initializing your aSelected and bSelected states by false value, to handle your scenario you can initialize your states by props in the constructor of your component, like below example:



            expo-barcode-scanner only works once with react-native version 0.64.2 and expo 43.0.0
            Asked 2022-Jan-12 at 17:35

            Because of Google Play, I had to update an old project of mine to the latest expo versions (version 43.0.0 to be exact). The idea is for the app to scan a QRCode and process the data, simply. However, expo-barcode-scanner only works once and after that I need to close and open the app again to work. Has anyone encountered this problem and (or) knows how to solve it? Below is my code:



            Answered 2021-Nov-12 at 21:14

            Welcome @Backup Gov18,

            This is a documented issue.

            Note: Only one active BarCodeScanner preview is supported currently. When using navigation, the best practice is to unmount any previously rendered BarCodeScanner component so the following screens can use without issues.

            There is a workaround.

            Instead of conditionally rendering the component, you could render it inside another dedicated screen component.

            This way, after this new screen reads the barcode, you could navigate back to your first screen. Navigating back may unmount this new screen. You can force unmount if you need to.

            As you are using react-navigation, you had better use .pop() instead of goBack().


            You can also use expo-camera instead of expo-barcode-scanner. expo-camera does not have this issue. It also offers more options like flashlight/torch and switching cameras.
