- would be a great product if they can have live preview / a good WYSIWYG editor
- really wish they had a better editor interface.

Tip: Enlarge video for google meet !

Reduce zoom !
Rest of the cards get smaller

-x-x-x-

When another person on a Meet call is sharing their screen, text may be hard to read due to the large number of UI elements taking up space.
Here are some things you can do to increase the size of the shared screen:
Pin the shared screen by hovering over it and pressing the Pin icon.
Hover over your own image and press the Minimize icon.
In the Meet Menu (triple dots) switch your Layout to "Focus".
Zoom out (!) by pressing `CTRL+minus` a couple of times. This reduces the size of the Meet controls at the bottom. You can later reset your zoom with `CTRL+0`.
Press `F11` to hide the browser UI. You can leave fullscreen by pressing `F11` again.
Ask the sharing person to zoom in, increase their font size, or only share a single window (resized to a smaller size).

NTFS partition not mounting on Linux ?
or mounting as a read only partition ?

sudo mount -o rw -t ntfs <device> <mount-point>

might help:
Generally if windows does not shut down properly, it leave the filesystem in a dirty state, hence linux refuses to mount it with write permissions !
Smart linux :)

FCM notifications on android emulator:

- this will save you a lot of hours and a lot of grief:

-x-x-x-
https://stackoverflow.com/a/23443757
- choose a google APIs target (although this is default on studio but still)

-x-x-x-

https://stackoverflow.com/a/22158163

"
The Android emulator is capable of receiving push notifications through GCM, however, it does require an additional step of actually logging a valid Google account into the emulator when it is running. This will need to be done for each emulator that you wish to use with push notifications through GCM.
"

This:
- it does require an additional step of actually logging a valid Google account into the emulator when it is running

https://stackoverflow.com/a/45807378
- Make sure your app is running in the background

Then,
make use of the postman collection to send an individual notification:
Stupid firebase product team removed the test option.
https://drive.google.com/file/d/16E6bxCiKaPUZzMpcKVWrpIpkuEbhyqW0/view?usp=sharing

Android Studio / CLI - builds
- Setting your AVD and Emulator directories to a spacious location (and not you ~/)

Basically set these env variables:
https://developer.android.com/studio/command-line/variables#android-sdk-home

export ANDROID_EMULATOR_HOME=<where-there-is-space>/.android

export ANDROID_AVD_HOME=$ANDROID_EMULATOR_HOME/avd

https://stackoverflow.com/a/52441381

Also, if you have copied you earlier emulator files, some of the paths may have been retained:

So you might have to manually change them
Eg.
/<where-there-is-space>/.android/avd/Pixel_2_API_29.ini

Some useful commands for testing if the move worked:

/Android/sdk/emulator/emulator -verbose -list-avds

Slow clap for Apple !!

Release notes without a date !!
https://developer.apple.com/documentation/xcode-release-notes/xcode-11_4-release-notes
nice !!

-x-x-x-
Anyway:
useful stuff; atleast notifications can be simulated after xcode 11.4

Simulator supports simulating remote push notifications, including background content fetch notifications. In Simulator, drag and drop an APNs file onto the target simulator. The file must be a JSON file with a valid Apple Push Notification Service payload, including the “aps” key. It must also contain a top-level “Simulator Target Bundle” with a string value that matches the target application’s bundle identifier.simctl also supports sending simulated push notifications. If the file contains “Simulator Target Bundle” the bundle identifier is not required, otherwise you must provide it as an argument (8164566)

xcrun simctl push <device> com.example.my-app ExamplePush.apns

molecular.services + redis --> max message size ?
- unable to find out so far

https://stackoverflow.com/a/5624569
may be this is it.. but dunno for sure

All string values are limited to 512 MiB. This is the size limit you probably care most about.

EDIT: Because keys in Redis are strings, the maximum key size is 512 MiB. The maximum number of keys is 2^32 - 1 = 4,294,967,295.

Values, on the other hand, can vary in size depending on their type. For aggregate data types (i.e. hash, list, set, and sorted set), the maximum value size is 512 MiB for each element, although the data structure itself can have up to 2^32 - 1 elements.

-x-x-x-
All it turns up in their docs is this:

RabbitMQ - installing plugins

- rabbitmq documentation definitely seems like someone with low English proficiency has written it.

RabbitMQ uses different ports for different purposes:
- https://www.rabbitmq.com/networking.html#ports

So in general one would need to tunnel to multiple ports for connect successfully to an instance behind a VPC / Firewall

For instance, a client that uses http apis and AMQP protocol to connect (Eg. rascal)
will need 5672 and 15672 both ports accessible

Firebase Crashlytics integration testing
- app should be able to start
- have a trigger for the crash, Eg. a button
- any other attached debugger should not inhibit the crash logging process by blocking the thread
- if the crash is causing the app to shutdown without being able to send out the logs (Eg memory errors etc) then the first condition becomes important

92.
This wasted a lot of my time:

https://firebase.google.com/docs/crashlytics/force-a-crash#adjust_your_projects_debug_settings

With your project still selected in the Xcode Navigator, open the Build Settings tab.
Click All at the top of the tab to display all build settings.
Search for "debug information format".
Set the Debug Information Format setting to DWARF with dSYM File.

https://firebase.google.com/docs/crashlytics/force-a-crash#test_it_out

Click ➡ Build and then run the current scheme in Xcode to build your app on a device or simulator.
Click ◾ Stop running the scheme or action in Xcode to close the initial instance of your app. This initial instance includes a debugger that interferes with Crashlytics.
Open your app again from the simulator or device.
Touch Crash to crash the app.
Open your app once more to let the Crashlytics API report the crash. Your crash should show up in the Firebase console within 5 minutes.

This importing style may come in handy some day:

t should work with import 'foo/module';. It will resolve file ./node_modules/foo/module.js or ./node_modules/foo/module/index.js and not something like ./node_modules/foo/node_modules/module/index.js if it expected (in that case you better to install module via npm).

Holy shoot !!!

Ionic wtf !?

Issue:

invalid GOOGLE_APP_ID in GoogleService-Info.plist

https://github.com/fechanique/cordova-plugin-fcm/issues/308

Solution:

GoogleService-Info.plist usually becomes corrupted for whatever reason.

Check platforms/ios/<Your Project>/Resources/ and platforms/ios/<Your Project>/Resources/Resources

There should be a GoogleService-Info.plist in both locations. One of these should be corrupt. Usually its the one furthest in.

Replace that one, and it should work.

And my reaction:
same as him:
https://github.com/fechanique/cordova-plugin-fcm/issues/308#issuecomment-320504517

holy sweet jesus batman!!!!!!!!! Like @codinronan said, this completely obscure solution fixed my issue. and I am not even using the FCM plugin, I am using the Firebase plugin. Rebuilt my app project from scratch and the problem still persisted...until I found this solution!!!!

thank you....Thank You....THANK YOU!!!!

and @ionic / cordova - wtf ?!?!?!?
