...ANSWER
Answered 2022-Mar-16 at 08:10If your image has a latest tag, the Pod's ImagePullPolicy will be automatically set to Always. Each time the pod is created, Kubernetes tries to pull the newest image.
Try not tagging the image as latest or manually setting the Pod's ImagePullPolicy to Never.
If you're using static manifest to create a Pod, the setting will be like the following:

QUESTION
In my iOS project were were able to replicate Combine's Schedulers implementation and we have an extensive suit of testing, everything was fine on Intel machines all the tests were passing, now we got some of M1 machines to see if there is a showstopper in our workflow.
Suddenly some of our library code starts failing, the weird thing is even if we use Combine's Implementation the tests still failing.
Our assumption is we are misusing DispatchTime(uptimeNanoseconds:) as you can see in the following screen shot (Combine's implementation)
We know by now that initialising DispatchTime with uptimeNanoseconds value doesn't mean they are the actual nanoseconds on M1 machines, according to the docs

QUESTION
I have a fresh project but was looking to test scheduled functions. Am I missing anything?
...ANSWER
Answered 2021-Nov-20 at 04:06When you are using scheduled functions in Firebase Functions, an App Engine instance is created that is needed for Cloud Scheduler to work. You can read about it here.They use the location that has been set by default for resources. I think that you are getting that error because there is a difference between the default GCP resource location you specified and the region of your scheduled cloud function. If you click on the cogwheel next to project-overview in Firebase you can see where your resources are located.
Check your Cloud Scheduler function details and see which region it has been deployed to. By default, functions run in the us-central1 region. Check this link to see how we can change the region of the function.
QUESTION
ANSWER
Answered 2021-Dec-17 at 09:28I'm not terribly familiar with your stack, so this is a high-level answer to hit on your "Why". There WILL be a more specific answer for you, somewhere down the pipe (e.g. someone that can confirm whether this thread is relevant).
While I'm no Spring Daisy (or Spring dev), you bind an expression to filmMono that resolves as the query select film.* from film..... You reference that expression four times, and it's resolved four times, in separate contexts. The ordering of the statements is likely a partially-successful attempt by the lib author to lazily evaluate the expression that you bound locally, such that it's able to batch the four accidentally identical queries. You most likely resolved this by collecting into an actual container, and then mapping on that container instead of the expression bound to filmMono.
In general, this situation is because the options available to library authors aren't good when the language doesn't natively support lazy evaluation. Because any operation might alter the dataset, the library author has to choose between:
- A, construct just enough scaffolding to fully record all resources needed, copy the dataset for any operations that need to mutate records in some way, and hope that they can detect any edge-cases that might leak the scaffolding when the resolved dataset was expected (getting this right is...hard).
- B, resolve each level of mapping as a query, for each context it appears in, lest any operations mutate the dataset in ways that might surprise the integrator (e.g. you).
- C, as above, except instead of duplicating the original request, just duplicate the data...at every step. Pass-by-copy gets real painful real fast on the JVM, and languages like Clojure and Scala handle this by just making the dev be very specific about whether they want to mutate in-place, or copy then mutate.
In your case, B made the most sense to the folks that wrote that lib. In fact, they apparently got close enough to A that they were able to batch all the queries that were produced by resolving the expression bound to filmMono (which are only accidentally identical), so color me a bit impressed.
Many access patterns can be rewritten to optimize for the resulting queries instead. Your milage may vary...wildly. Getting familiar with raw SQL, or else a special-purpose language like GraphQL, can give much more consistent results than relational mappers, but I'm ever more appreciative of good IDE support, and mixing domains like that often means giving up auto-complete, context highlighting, lang-server solution-proofs and linting.
Given that the scope of the question was "why did this happen?", even noting my lack of familiarity with your stack, the answer is "lazy evaluation in a language that doesn't natively support it is really hard."

This script fails to deserialize my Object. Error was TypeError: this.buf.readUInt32LE is not a function
ANSWER
Answered 2021-Oct-26 at 04:27I looked at the dependencies in the codesandbox page and it imports globally the buffer package. I tried doing the same locally with require('buffer/'), but no luck. However, it works using it as const Buffer = require('buffer/').Buffer and calling the method Buffer.from to get the buffer from the serialized data.
