How to remove an application "tile" from Anaconda Navigator Home tab - anaconda

I have a bunch of apps that I will never use (GLueviz, Orange3, Rstudio) that I would like gone from my Home tab. They are not installed, but there is no way to remove the tile for the app. The gear icon isn't going to do it for me.
I dug into the config file ~/.anaconda/navigator/anaconda-navigator.ini and nothing obvious there. Oddly it says that vscode_enable = False yet VS Code does appear as a tile.
I'm running 1.9.12 individual edition on MacOS Catalina.

On navigator 2.1.1, I was able to comment out the two lines for Datalore and IBM Watson in ~/opt/anaconda3/pkgs/anaconda-navigator-2.1.1-py39_0/lib/python3.9/site-packages/anaconda_navigator/api/external_apps/__init__.py.
web_apps: 'typing_extensions.Final[typing.Mapping[str, WebAppInitializer]]' = {
#'datalore': DataloreApp, # noqa: F405
#'ibm_watson': IBMWatsonApp, # noqa: F405
}

Based on the Anaconda docs https://docs.anaconda.com/navigator/tutorials/custom-tiles/, you can create a yaml file that will allow you to disable some of the tiles.
In practice, I've found this works for some apps, but may not work for all. For example, some of the gnuradio apps go away, but many do not (e.g., gnuradio-build-deps).
Create a yaml file at ~/.anaconda/navigator/applications/ (MacOS)
Add the code to disable an application from view:
glueviz:
is_available: false

Prevent or clear app state persistence for MacOS SwiftUI Document Based App

I am developing a MacOS Document based app using SwitfUI on MacOS 12.0.1 using Xcode 13.1 on a MacbookPro M1 Pro. I am encountering an issue that the app is always re-opening the document browser at the last used directory. Which is OK when it is on the Machine but a pain if the last used was on a network drive. I am trying to find a way of suppressing this "always restore using the last directory" mode of operation.
I have tried using the #NSApplicationDelegateAdaptor approach and implementing;
func applicationSupportsSecureRestorableState(_ app: NSApplication) -> Bool {
print(#function + " returning false")
return false
}
within my NSApplicationDelegate class, which does get called (although it seems sometimes after the dialog is presented), however this does not stop the app secretly remembering the last directory.
Does any know where this information might be being hidden or if it can be suppressed ?
I have looked for, but cannot find, a way of injecting a starting directory into a DocumentGroup as a possible solution.
TIA Alan.
Ok, for anyone who ends up here looking for a similar issue.
After a chunk of digging I found the answer, for me, was to add
UserDefaults.standard.removeObject(forKey: "NSNavLastRootDirectory")
into the app startup. It was also suggested to do
UserDefaults.standard.removeObject(forKey: "NSNavLastCurrentDirectory")
However, just doing the first appears to suppress the file open dialog, doing both causes the file open dialog to open with the user Documents directory.

Strange lines appearing instead of cells when rendering jupyter notebook from a remote server [duplicate]

I am using quite large notebooks in JupyterLab to run Python code. They contain many Markdown cells with text and some images. The problem I am having is that when I close the Notebook and reopen, some of these cells have collapsed and can't be expanded (show as a horizontal line). Sometimes I will get a message telling me how many cells are hidden but they can't be expanded. Others seem to have disappeared completely.
Occasionally, I can get some cells to expand if I reload the page. I thought it may have been because I had lots of Markdown header levels and those too far down the hierarchy were collapsing. However, even removing many of the header levels has not solved the problem.
Have others had this issue and has anyone been able to resolve it? Thanks!
Edit: Thank you Vinson. My Jupyter Version is Version 3.1.7, running on Google Chrome (Version 92.0.4515.159 (Official Build) (64-bit)), on Windows machine.
This was fixed in JupyterLab 3.1.10 (this PR) released on 2021-09-01 - the issue should disappear after you upgrade and restart JupyterLab:
# (or conda-forge equivalent if you use conda/mamba)
pip install -U "jupyterlab>=3.1.10"
If however, you are unable to update right now, you can use a workaround of disabling the placeholder rendering, by going to Advanced Settings Editor -> Notebook and in the right pane (User Preferences) paste the following:
{
"renderCellOnIdle": false,
"numberCellsToRenderDirectly": 10000000000000
}
then press save and reload JupyterLab.
I do not know how to fix this with conda. But option 2 is working for me. For those who are not family with the deep tech, you can try these, two extran configure there are shown the line numbers.
{
"markdownCellConfig": {
"lineNumbers": true
},
"codeCellConfig": {
"lineNumbers": true
},
"renderCellOnIdle": false,
"numberCellsToRenderDirectly": 10000000000000
}

Install a personal firefox web extension permanently

Previously, I could write an addon for personal usage packed as something.xpi and I clicked on it to install it.
After a while, mozilla introduced xpinstall.signatures.required which you could still get around it.
However, it did not stop stabbing developers who are interested to have a personal addon isolated from the world. Today, only web extensions are working and my XUL based addon is thrown away. The tutorials only talk about temporary installation of a web extension while I want my one runs on firefox forever.
Beside whether I can use web extension to write into files or create a GUI in an independent page, I have a bigger challenge:
How can I install a local web extension permanently without creating a Mozilla account for personal usage?
Navigate to the folder where your extension is located. You can build it in the usual way using web-ext:
web-ext build
You can install this ZIP file permanently in Firefox by going to about:addons and dragging this file into the tab.
In order for this to work, you need to set xpinstall.signatures.required to false in about:config (works only for Nightly and maybe Developer Edition).
Apart from setting xpinstall.signatures.required to false, you need to add this to your manifest.json:
"browser_specific_settings": {
"gecko": {
"id": "some-name#example.org"
}
}
Found on https://www.reddit.com/r/firefox/comments/blqffs/how_to_permanently_add_temporary_addon/exh2u3o/, thanks to "alexherbo2".
You need a "blueish" Firefox -- Developer Edition (effectively beta) or Nightly (unstable, updated every night).
You can get them from https://mozilla.org/firefox/channel/desktop/.
Then xpinstall.signatures.required will work again.
(As for permissions--you can create a GUI in a tab or a popup, but I don't think you can do it in a separate window (unless you do a webpage-style popup window). You won't be able to write to arbitrary files anywhere on the system--which is a good thing! You can write to the Downloads folder, and read/write some sort of internal storage, but that may not expose the actual files involved. For more information see https://developer.mozilla.org/en-US/Add-ons/WebExtensions/Working_with_files.)
What you should be looking for is having your extension signed by Mozilla as Unlisted.
See Mixing Listed and Unlisted Add-ons on addons.mozilla.org blog post for an overview.
That way, AMO does not host nor (normally) review your extension; it simply runs some basic automated checks and immediately signs your extension so that it can be privately distributed as an XPI.
For those interested in developing/running an extension from a local directory without having to package or load it manually via "Load Temporary Addon..." from about:debuggin#/runtime/this-firefox please go to this github repository.
From the README.md:
The procedure involves a few steps, but it needs to be done only once.
First you need to enable AutoConfig aka userchrome.js by copying the file config-prefs.js to [Your Firefox install directory]/defaults/pref
Note: For best security, on Windows it is best to leave your Firefox install in "c:\Program Files" so that your config-prefs.js and userChrome.js can only be modified when you are in root/admin mode.
Then you need to edit the file userChrome.js and modify the function installUnpackedExtensions() to reflect the locations of your own addons.
The modified userChrome.js then must be copied to your Firefox installation directory. For example on Windows this is usually "c:\Program Files (x86)\Mozilla Firefox" for the 32-bit version of Firefox. You can rename the file, but remember to modify the corresponding line pref("general.config.filename", "userChrome.js") in defaults/pref/config-prefs.js
Now your addons from your local directories will be loaded automaticaly whenever Firefox starts. After editing your code remember to reload it from about:debuggin. You can also get there via the menu by selecting "More Tools", then "Remote Debugging", and click on "This Firefox" on the left side (but the quickiest way is to bookmark it and then add a bookmark keyword such as "dbg" for quick access.)
Please note that this is an automated install of the extension every time Firefox starts, so it is not quite the same as a "permenent install". That is, this procedure has exactly the same effect as clicking on "Load Temporary Addon..." from the about:debuggin page, just that the process is now automated via userChrome.js. This means that if you have code that does something after the installation of the extension such as browser.runtime.onInstalled.addListener(details => { if (details.reason == "install") { ...do something after install... }); then this code will be called every time Firefox is launched.
You can try setting the preference extensions.legacy.enabled (this will only work in Nightly or Dev Edition).

Running AntlrWorks2 stand-alone on Windows 7

I must be missing something. After downloading AntlrWorks2 I found the executable bin/antlrworks2.exe and bin/antlrworks264.exe. Aren't these supposed to be the standalone version of the tool? Neither works for me; after a NetBeans splash screen, the first times around I got an error message on missing packages; after a couple of times I chose to go on regardless, but now (still after the initial spash screen) there is simply nothing happening at all.
I can't find any tutorial or manual detailing how to run AntlrWorks stand-alone, so any help is much appreciated.
This is due to a bug in the NetBeans platform. I filed a report but it hasn't received a reply yet:
Cannot launch platform application after moving installation folder
Here is a workaround that does not delete any preferences you have customized:
I found that deleting just the var folder under the user's generated
.antlrworks2 settings folder resolves the issue...
Still an issue as of date of this post. Deleting the .antlrworks2 folder from \users\username\AppData\Roaming does work - you can find this folder by putting %APPDATA% into your file explorer address bar (exactly as shown) - that will go to the app data folder for your current user login session. Delete the .antlrworks2 folder and then re-run the app.

Using OSX Security-Scoped Bookmarks in a Firemonkey app

I have been developing an OSX app with Delphi XE3 and running into various problems. The latest one is with the sanboxed version built for the Apple Appstore.
The user has to select an arbitrary folder and the app needs to get access to it. Since there is a problem with the OpenDialog, I had to turn to drag-drop functionality instead.
The user drags a folder to the app, the sandbox gives the app temporary access to it and all works properly.
To preserve the access to this folder when the app is restarted I have to use the so-called "security-scoped bookmarks"
I am having two issues with them:
1) How to add the "com.apple.security.files.bookmarks.app-scope" entitlement to an XE3 firemonkey app? It is not available in the Project Options->Entitlements. If I add it manually in the ".entitlements" file it gets overwritten when the app is built.
So is there a way to add a custom entitlement that is not in the list in the project options?
2) To create the bookmark I should use the NSURL.bookmarkDataWithOptions method. I think it should be used like this, but I am not sure of the exact syntax:
var
URL: NSURL;
Err: NSError;
Data: NSData;
...
URL := TNSURL.Create;
Data := URL.bookmarkDataWithOptions(NSURLBookmarkCreationWithSecurityScope, nil, #Err);
...
Maybe there should be a call to Wrap(...) instead of Create.
I have not yet experimented with it, because it is pointless without the answer to issue 1).
It seems no one has written anything about these problems for Delphi, but I hope someone here has experience with that.
Thanks in advance.
Edit:
For problem 1) I tried to add edit manually the ".entitlements" file in the OSX32 folder and set it to read-only to prevent it from being overwritten. It was too easy to be true of course, because the linker complained that the file can not be modified...
OK, I finally found the way to manually add entitlements that are not available in the Project Options > Entitlements.
Instead of selecting the "App Store" build in the Project Manager you have to select a Normal release build and deploy the application as usual.
The application gets deployed in the PAServer scratch-dir as APP package. Inside this package there is an "Entitlements.plist" file, which is in XML format and can be edited with a text editor. It is quite obvious how to add new entitlements once you open the file.
After it is edited, the app has to be code-signed manually and a package has to be prepared. It is slightly more complicated than using the Delphi IDE, but there are instructions about it on the Embarcadero and Apple websites and it actually went without problems.
Still haven't tried the bookmarkDataWithOptions functions.
An alternative could be to deactivate the checkbox for the entitlements-file in the deployment page.
But attention: Evry time you change between Build/Release or App Store/Normal, delphi activates the checkbox. That means you have to deactivate it again in the deplayment-page, to avoid the transfer of this file to the mac PC.
By the way: Do you have tryed meanwhile the StartAccessingSecurityScopedResource function?
In the MacApi.Foundation unit the function is not declared in the NSURL interface.
Do you have found a way to use this function?
