QUESTION
looking to understand the order in which kubenetes examine the pods using the 3 type of probes- startup, readiness and live.
How to understand or design these 3 probes correctly for normal applications? What is the chance of getting conflict or breaking the application if the startup probe has wrong entries
...ANSWER
Answered 2021-Jun-15 at 16:06This runs first. When it succeeds, the Readiness Probe and Liveness Probe are run continuously. If this fails, the container is killed.
Use this for "slow staring apps", you can use the same command as Liveness if you want.
The kubelet uses startup probes to know when a container application has started. If such a probe is configured, it disables liveness and readiness checks until it succeeds, making sure those probes don't interfere with the application startup. This can be used to adopt liveness checks on slow starting containers, avoiding them getting killed by the kubelet before they are up and running.
From configuring probes
Liveness probeThis is used to kill the container, in case of a deadlock in the application.
Readiness probeThis is used to check that the container can receive traffic.

I am attempting to add another checkbox to this program but for some reason it will not display when I run the program. Only the check box for the blue pill displays. I have attempted to add a couple things or change the way the program is structured, but nothing I have done so far has helped.

Answered 2021-Jun-15 at 04:38When you're stuck on a problem, it never hurts to go back and consult the documentation.
You'll find information like this:
A border layout lays out a container, arranging and resizing its components to fit in five regions: north, south, east, west, and center. Each region may contain no more than one component, and is identified by a corresponding constant: NORTH, SOUTH, EAST, WEST, and CENTER. When adding a component to a container with a border layout, use one of these five constants...

Good day everyone, I am currently struggling with writing mysql query which should make chat group from messages. App which I am making is taking data from other service, so it's not up to me to also manage chat groups, I need take this info from messages themselves.
My table of messages looks like this:
id sendAddr receiveAddr lastMessage text read 1 Ccbbd6uUZF2GD5wE5LEfjGPA3YWPjoLC6P CMKovgETx2oYxhoYKAeSakmipBjbmQ9ZHF 2021-06-02 12:57:39 test3 0 5 Ccbbd6uUZF2GD5wE5LEfjGPA3YWPjoLC6P CMKovgETx2oYxhoYKAeSakmipBjbmQ9ZHF 2021-06-02 13:00:44 test3 0 7 CMKovgETx2oYxhoYKAeSakmipBjbmQ9ZHF Ccbbd6uUZF2GD5wE5LEfjGPA3YWPjoLC6P 2021-06-10 23:13:59 testVPS 0 8 CMKovgETx2oYxhoYKAeSakmipBjbmQ9ZHF CYfMNQ62u1qwhCBqXzcmeJ8D9j4Yc1Pwef 2021-06-10 20:03:59 neco 0 9 CYfMNQ62u1qwhCBqXzcmeJ8D9j4Yc1Pwef CMKovgETx2oYxhoYKAeSakmipBjbmQ9ZHF 2021-06-10 21:03:59 test 0My only input data which I sent from my mobile app is receiveAddr
so I need to add this to group anything which containes address in either sentAddr
or receiveAddr
, here is representation of what I want to achieve
It needs to have latest text
counted amount of 0 in read
column and lastMessage
which is time of last message
I came up with something which sort of works if the user of the mobile app would be just receiving messages, which would be this:
SELECT sentAddr, COUNT(IF(campus.messages.read = 0, 1, NULL)) as unread, max(receiveTime) as lastMessage, max(text) as text FROM campus.messages WHERE (SELECT max(receiveTime) FROM campus.messages) AND receiveAddr = 'CMKovgETx2oYxhoYKAeSakmipBjbmQ9ZHF' GROUP BY sentAddr, receiveAddr
But sadly that does not get me a text from the latest message and not even taking into account that if the same user send some message, it shows as different group, which is not really helpful. I also came up with something which groups sendAddr and receiveAddr into one group no matter if it's on sending or receiving side:
GROUP BY CONCAT(LEAST(receiveAddr,sentAddr),' ', GREATEST(receiveAddr, sentAddr))
However in that case I can't with this added to upper query, it does not retrieve latest text, which is useless. So is there any chance of doing this with one query, no matter how long and convoluted it would be? And just to remind, only input data is user's address, which can be either sending or receiving address from the table. So is there any solution to this?
Version of the mysql database is 8.0.25

I don't really know where the error is, for me, it's still a mystery. But I'm using Laravel 8 to produce a project, it was working perfectly and randomly started to return this error and all projects started to return this error too. I believe it's something with Redis, as I'm using it to store the system cache. When I go to access my endpoint in postman it returns the following error:

Answered 2021-Jun-12 at 01:50Your problem is that you have set SESSION_CONNECTION=session

readinessProbe: Indicates whether the container is ready to respond to requests. If the readiness probe fails, the endpoints controller removes the Pod's IP address from the endpoints of all Services that match the Pod. The default state of readiness before the initial delay is Failure. If a Container does not provide a readiness probe, the default state is Success
If the readiness probe fails (and the Pod's IP address is removed from end point), what happens next? Will the Pod's readiness probe conditions be checked again? Will it check again after initial delay? Is there any chance the Pod's IP address is added to the end point again (if the Pod self healed after readiness probe fails)? Will that Pod receive traffic again incase if it's healed?
...ANSWER
Answered 2021-Jun-14 at 03:24It's checked again after the same periodSeconds
delay as usual and then when it passes successThreshold
times in a row it will be considered Ready again with all the normal behaviors that entails.
QUESTION
i have an error that i just dont find a solution for. I created a little messenger thingy in flutter and have a problem when using a NetworkImage inside one of my chat bubbles.
When i send the image as message, it is displayed without problem in the bubble. Also when i send multiple images, it is no problem and they extend beyond the screen and i can just scroll up and down without any problems.
Though when i reopen the room screen and there are multiple images and they extend over the visible screen i get _CastError (type 'Null' is not a subtype of type 'List' in type cast) from network_image dart file. BUT this only happens after a hot restart. If i just navigate back and then reopen the room screen its also all fine, but as soon as i hot restarted once i always get the error when trying to open a room, which has images extending the visible space.
Iam still kinda new to flutter, so i know my code sucks mostly but this time i just dont even find a "dirty" way to solve it.
Flutter 2.2.0 (beta channel)
Dart 2.13.0

Edit 1: i removed a lot to make it easier to read.
Edit 2: i found it to be somehow connected to using the downloadURL from Firebase Storage. When i replace the url with just some test png url it doesnt seem to be a problem.
...ANSWER
Answered 2021-Jun-14 at 11:07Ok, i kind of found the problem. I took the Firebase servertimestamp as variable for the filename in the Firebase Storage. That of course only resulted in the filename being
FieldValue(Instance of 'MethodChannelFieldValue')
Though i dont really understand why that was a problem, but now with a normal Datetime toString timestamp it all works perfectly fine. Maybe its some special character escaping in the generated downloadURL from Firebase Storage with this kind of filename.
QUESTION
I just updated macOS Big Sur 11.3 today. Nothing is weird until I open Xcode and run my app in simulator. The app launch is becoming veryyy slow and sometimes it crash when there is background thread like URLSession. I have xcode 12.5 before in macOS 11.2.1 and no problem with debugging dan running in simulator.
These are what I have done so far but still no luck:
- Try create new blank project, problem still exist
- Clean derived data
- Clean project
- Force quit xcode.
- Restart macbook
These are my assumtion of solution but still have no chance to do right now:
- Reinstall iOS 14 simulator/ install another simulator with different OS version (I will try this when I am in somewhere with high speed internet connection)
- Reinstall xcode (Still no high speed internet connection)
- Downgrade macOS and xcode (Still no high speed internet connection)
- Install di real device (I have no single iphone)
Have you experience this? How to solve this problem? I have not tested in real device because I don't have iOS device.
...ANSWER
Answered 2021-Jun-14 at 08:34This is already discussed in Apple Developer Forum lately. Still not sure what’s going on here, but some people pointed out about dyld being slowed down after macOS Big Sur 11.3. So this has nothing to do with Xcode. All Xcode version in macOS 11.3 (maybe) get affected with this issue. Apple should release macOS update to resolve this issue.
In my case, this issue only appear in Simulator. It is normal in real device. My advice is try to run it in real device and wait for Apple to fix this. But if you only can run your app in Simulator, you should untick/uncheck the debug executable option in Edit Scheme -> Run
Update: The downside of uncheck the debug executable is you are no longer use debugger. So some feature like breakpoint will not work.
Update: Some people with macOS Big Sur 11.4 also reporting that this issue still exist.
Update: This bug has been fixed in macOS Monterey Beta and Xcode 13 Beta.

I've got a sample table:
I have a Sample table which has a "creationDate" as an atribute. What I want is a way to increment(update) the "numOfTimesUpdated" attribute each 24h since the creationdate. so lets say "creationdate" is 01.01.2021 12:12 AM => numOfTimesUpdated=0, 02.01.2021 12:12 AM => numOfTimesUpdated=1, 03.01.2021 12:12 AM => numOfTimesUpdated=3.
How can I implement something like this in the best way?
Does SQLite has some kind of background scheduler/trigger where a UPDATE Query gets automatically called? Or Is my only chance the client side(application) using smth. like an ApplicationManager?
...ANSWER
Answered 2021-Jun-14 at 06:08How can I implement something like this in the best way? You don't appear to even need a numberOfTimesUpdated column as the number of days since the creationDate can be calculated when required.
- If the date/time were stored in a supported format (e.g. YYYY-MM-DD HH:MM) it is very simple.
