QUESTION
I have a simple component see below, that basically attempts to grab some data from the formik FormContext using the useFormikContext hook.
However when attempting to write unit tests for this component it wants me to mock the hook which is fine, however, mocking the hook with typescript means returning well over 20 properties most of which are a variety of methods and functions.
Has anyone found a better way of doing this? Just seems a bit annoying even if I get it to work as I only need 1 field from the hook.

...ANSWER
Answered 2021-Dec-22 at 13:29I resolved this issue not 100% sure it is the best solution but have posted here in case it helps anyone with a similar issue.
I basically overwrote the FormikType allowing me to ignore all of the fields and methods I wasn't using, it clearly has some drawbacks as it is removing the type-safety, but I figured since it was only inside the unit test it is somewhat okay.

I have a few large static arrays that are used in a resource constrained embedded system (small microcontroller, bare metal). These are occasionally added to over the course of the project, but all follow that same mathematical formula for population. I could just make a Python script to generate a new header with the needed arrays before compilation, but it would be nicer to have it happen in the pre-processor like you might do with template meta-programming in C++. Is there any relatively easy way to do this in C? I've seen ways to get control structures like while loops using just the pre-processor, but that seems a bit unnatural to me.
Here is an example of once such map, an approximation to arctan, in Python, where the parameter a is used to determine the length and values of the array, and is currently run at a variety of values from about 100 to about 2^14:
ANSWER
Answered 2022-Mar-08 at 22:33Is there any relatively easy way to do this in C?
No.
Stick to a Python script and incorporate it inside your build system. It is normal to generate C code using other scripts. This will be strongly relatively easier than a million lines of C code.
Take a look at M4 or Jinja2 (or PHP) - these macro processors allow sharing code with C source in the same file.
QUESTION
I have an app that has been running for years with no changes to the code. The app has OAuth2.0 login with a variety of providers including Google Workspace and Office 365. Since the launch of Chrome V97 (i.e. in last few days), the O365 login has stopped working, as for some reason, the auth cookie does not get set in the OAuth callback GET handler. The code that sets the cookie is the same code that is run for Google Workspace, yet this works. It also works on Firefox. Something about Google Chrome V97 is preventing cookies from being set, but only if it round trips to O365 first.
To isolate the issue, I have created a fake callback which manually sets a cookie, thereby removing all of the auth complication. If I call this by visiting the URL in a browser, then the cookie sets as expected. Yet if I perform the O365 OAuth dance first, which in turn invokes this URL, then the cookie does not get set. Try exactly the same thing with Google Workspace and it works.
I have been debugging this for hours and hours and clean out of ideas.
Can anyone shed any light on what could be causing this odd behaviour?
...ANSWER
Answered 2022-Jan-10 at 19:43We ran into this too, fixed by adding SameSite=none; to the auth cookie. In Chrome 97 SameSite is set to Lax if missing. See more here https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Set-Cookie/SameSite
QUESTION
I understand there are a variety of techniques for sharing memory and data structures between processes in python. This question is specifically about this inherently shared memory in python scripts that existed in python 3.6 but seems to no longer exist in 3.10. Does anyone know why and if it's possible to bring this back in 3.10? Or what this change that I'm observing is? I've upgraded my Mac to Monterey and it no longer supports python 3.6, so I'm forced to upgrade to either 3.9 or 3.10+.
Note: I tend to develop on Mac and run production on Ubuntu. Not sure if that factors in here. Historically with 3.6, everything behaved the same regardless of OS.
Make a simple project with the following python files
myLibrary.py
...ANSWER
Answered 2022-Jan-03 at 23:30In short, since 3.8, CPython uses the spawn start method on MacOs. Before it used the fork method.
On UNIX platforms, the fork start method is used which means that every new multiprocessing process is an exact copy of the parent at the time of the fork.
The spawn method means that it starts a new Python interpreter for each new multiprocessing process. According to the documentation:
The child process will only inherit those resources necessary to run the process object’s
run()method.
It will import your program into this new interpreter, so starting processes et cetera sould only be done from within the if __name__ == '__main__':-block!
This means you cannot count on variables from the parent process being available in the children, unless they are module level constants which would be imported.
So the change is significant.
What can be done?
If the required information could be a module-level constant, that would solve the problem in the simplest way.
If that is not possible (e.g. because the data needs to be generated at runtime) you could have the parent write the information to be shared to a file. E.g. in JSON format and before it starts other processes. Then the children could simply read this. That is probably the next simplest solution.
Using a multiprocessing.Manager would allow you to share a dict between processes. There is however a certain amount of overhead associated with this.
Or you could try calling multiprocessing.set_start_method("fork") before creating processes or pools and see if it doesn't crash in your case. That would revert to the pre-3.8 method on MacOs. But as documented in this bug, there are real problems with using the fork method on MacOs.
Reading the issue indicates that fork might be OK as long as you don't use threads.
QUESTION
I am trying to replace words in a string with matches from an object. If a word matches the property from an object, it will be replaced by the relevant value. My problem is cases where there is a character before and after the word that should be replaced, unless the character is a whitespace or a hyphen.

Answered 2021-Dec-20 at 07:01I would just use an alternation here. Create an array of description variant terms to find, and then do a global replacement.
QUESTION
I have an application running on my local machine that uses React -> gRPC-Web -> Envoy -> Go app and everything runs with no problems. I'm trying to deploy this using GKE Autopilot and I just haven't been able to get the configuration right. I'm new to all of GCP/GKE, so I'm looking for help to figure out where I'm going wrong.
I was following this doc initially, even though I only have one gRPC service: https://cloud.google.com/architecture/exposing-grpc-services-on-gke-using-envoy-proxy
From what I've read, GKE Autopilot mode requires using External HTTP(s) load balancing instead of Network Load Balancing as described in the above solution, so I've been trying to get that to work. After a variety of attempts, my current strategy has an Ingress, BackendConfig, Service, and Deployment. The deployment has three containers: my app, an Envoy sidecar to transform the gRPC-Web requests and responses, and a cloud SQL proxy sidecar. I eventually want to be using TLS, but for now, I left that out so it wouldn't complicate things even more.
When I apply all of the configs, the backend service shows one backend in one zone and the health check fails. The health check is set for port 8080 and path /healthz which is what I think I've specified in the deployment config, but I'm suspicious because when I look at the details for the envoy-sidecar container, it shows the Readiness probe as: http-get HTTP://:0/healthz headers=x-envoy-livenessprobe:healthz. Does ":0" just mean it's using the default address and port for the container, or does indicate a config problem?
I've been reading various docs and just haven't been able to piece it all together. Is there an example somewhere that shows how this can be done? I've been searching and haven't found one.
My current configs are:

Answered 2021-Oct-14 at 22:35Here is some documentation about Setting up HTTP(S) Load Balancing with Ingress. This tutorial shows how to run a web application behind an external HTTP(S) load balancer by configuring the Ingress resource.
Related to Creating a HTTP Load Balancer on GKE using Ingress, I found two threads where instances created are marked as unhealthy.
In the first one, they mention the necessity to manually enable a firewall rule to allow http load balancer ip range to pass health check.
In the second one, they mention that the Pod’s spec must also include containerPort. Example:
QUESTION
I have several hundred Google Apps Script projects and have a variety of Bash scripts for managing the projects using the clasp tool (a Node.js app). Many of the scripts require using clasp pull to first pull the projects locally before taking some actions on the local files, so I have a script which loops through local clasp project folders and runs clasp pull on each. The loop iterates through directories sequentially so if it takes 3-4 seconds to pull a project, it ends up taking 5-6 minutes to run it per 100 projects.
My goal is to be able to run the clasp pull commands in parallel so that they all start at the same time, and to be able to know which projects were successfully pulled vs which projects failed to be pulled.
Given a directory structure like this:
...ANSWER
Answered 2021-Oct-23 at 06:57
- The script does not cause a new shell prompt to appear during the execution of the script.
The new shell prompt is occurring because you are creating a new subshell in the while loop (for further guidance on how subshells work in bash, reference this page from tldp.org: link). To prevent this from occurring, call the command directly without placing them within parentheses.
- The script outputs a line indicating the success or failure of each clasp pull operation, referenced by the directory name of the project (where the .clasp.json file was found).
You can generally catch if a command fails by adding an || after the command (e.g. grep "foobar" file.txt || echo "Error: 'foobar' not found in file.txt"). You could also put the command in an if/else and echo the appropriate status message for each.
- Bonus: suppress the output of clasp pull so the script only shows the success or failure result of each project (referenced by the directory name).
Note: This response uses the aforementioned solution from the second question. You could create 2 arrays—1 for success and 1 for failures, and then inside of the if/else statements, add the current iteration element to the correct array.
Feel free to ask for clarification if any part of the above was not clear!
QUESTION
In order to record the composite-video signal from a variety of analog cameras, I use a basic USB video capture device produced by AverMedia (C039).
I have two analog cameras, one produces a PAL signal, the other produces an NTSC signal:
- PAL B, 625 lines, 25 fps
- NTSC M, 525 lines, 29.97 fps (i.e. 30/1.001)
Unfortunately, the driver for the AverMedia C039 capture card does not automatically set the correct video standard based on which camera is connected.
GoalI would like the capture driver to be configured automatically for the correct video standard, either PAL or NTSC, based on the camera that is connected.
ApproachThe basic idea is to set one video standard, e.g. PAL, check for signal, and switch to the other standard if no signal is detected.
By cobbling together some examples from the DirectShow documentation, I am able to set the correct video standard manually, from the command line.
So, all I need to do is figure out how to detect whether a signal is present, after switching to PAL or NTSC.
I know it must be possible to auto-detect the type of signal, as described e.g. in the book "Video Demystified". Moreover, the (commercial) AMCap viewer software actually proves it can be done.
However, despite my best efforts, I have not been able to make this work.
Could someone explain how to detect whether a PAL or NTSC signal is present, using DirectShow in C++?
The world of Windows/COM/DirectShow programming is still new to me, so any help is welcome.
What I triedUsing the IAMAnalogVideoDecoder interface, I can read the current standard (get_TVFormat()), write the standard (put_TVFormat()), read the number of lines, and so on.
The steps I took can be summarized as follows:
...ANSWER
Answered 2021-Nov-16 at 15:35The mentioned property page is likely to pull the data using IAMAnalogVideoDecoder and get_HorizontalLocked method in particular. Note that you might be limited in receiving valid status by requirement to have the filter graph in paused or running state, which in turn might require that you connect a renderer to complete the data path (Video Renderer or Null Renderer, or another renderer of your choice).

So I been trying to get my first Wear Os watch face published But when I submit I keep it keeps getting rejected. I only lightly changed the Sample Android studio provides nothing much changed but the background and the way the hands move. I keep getting this. I really do not know why it keeps getting rejected. I make sure it works for both square and round wear OS. I keep getting this message
Step 1: Fix the eligibility issue with your app
During review, we detected the following eligibility issue and were unable to accept your app for Wear OS:
The basic functionality of your app does not work as described in App Bundle
- Wear OS functionality should work as expected or as described in the app's Google Play Store listing. Please make sure to test your app on a variety of Wear OS devices and configurations.
For example, Hours and Minutes hands are not placed in the center of the watch face on Square Device. as shown/described on the store listing.
