QUESTION
I recently suspended a VM in GCP. After a few days, I resumed it, but I can't connect the instance in any way.
With a ping
command pointing to the external IP, I obtain no response. Sending an HTTP request using a web browser doesn't work either, of course.
If I try connecting using SSH (either with the gcloud
or the browser window), I get a connection timeout (Putty) or a Code: 4003 Reason: failed to connect to backend
. I did try to add explicitly the SSH public key again editing to the VM setup. Also, I have a VM for a different environment which I never suspended, and that has no issued to connect.
I checked the Firewall rules, everything seems to be ok.
If I enable and connect to the serial console I see it's constantly logging these weird messages:
...ANSWER
Answered 2021-Mar-24 at 20:30Just in case anyone is going through this same issue, I now solved it by executing the RESET
operation on my VM.
After struggling for quite a lot of hours trying to figure out (unsuccessfully) a suitable solution for this, I think this will be the simpler solution, especially keeping in mind that my VM came from a suspended state.

I'm trying to receive stock data for about 1000 stocks, to speed up the process I'm using multiprocessing, unfortunately due to the large amount of stock data I'm trying to receive python as a whole just crashes.
Is there a way to use multiprocessing without python crashing, I understand it would still take some time to do all of the 1000 stocks, but all I need is to do this process as fast as possible.
...ANSWER
Answered 2021-Jan-31 at 19:18Ok, here is one way to obtain what you want in about 2min. Some tickers are bad, that's why it crashes.
Here's the code. I use joblib for threading or multiprocess since it doesn't work in my env. But, that's the spirit.
QUESTION
I have developed an ios application that allow users to edit a musical score sheet and now i'd like to implement data persistence to prevent the discarding of changes.
Reading on ios documentation i've noticed that exists different ways to improve data persistence and I believe that the best way for my application is Core Data. Considering that my application use a lot of custom object i met a lot of problems.
I'm trying to use core data to save an entity, referred to a score sheet, composed by two attributes:
- name: String
- score: Array of another custom object (Measure), composed by other custom object (Score Element)
According to documentation and other q/a I've decided to use a Trasformable type on the model:
So I've declared a generic class used as trasformer for score attribute:

Firstly, the computed transformer name is not the same as the one you're trying to use. When this line executes, and T
is Measure

QUESTION
I realize this question or similar has been asked 20 times and I've read through all of the entries and tried the fixes with no luck.
I am getting a 405 error when trying a POST request from the DB only when using heroku.
My code works when deploying from my own local server both from src and build folders. I have tried the following:
- update Atlas whitelist to 0.0.0/0
- created an ENV key in Heroku and set up code to use that.
- reset my db password on atlas
- added cors module to Express code.
I'm completely at a loss as to why this isn't working now.
Here's the code in question with the first POST Request:
App.mjs
...ANSWER
Answered 2020-Jul-18 at 01:55I figured out what my mistake was after some help from a rep at clever-cloud. It turns out all my routing was correct except for the fact that I had capitalized App.mjs in my package.json when the file was app.mjs. On my local host environment it didn't matter but on the linux based server(s) the case matters and so it couldn't connect correctly.
It didn't have a clear error message, and my inexperience made it so I didn't understand my mistake. Many thanks to the support team at clever-cloud! I was able to get it working on clever-cloud, heroku, and a shared-server A2 hosting site.
QUESTION
The situation is that I want to connect two cluster IP services that are inside a tenant which already has Traefik as NodePort so that any of these two services can be a LoadBalancer because the NodePort is used by Traefik.
The two services I am trying to connect work as follows. The first one, which I called "Master", will receive a post from the client with a text and will call the other service, called "slave", which will add some text ("Hola Patri") to the text sent by the client. The two services are flask services defined by the app.py in the Docker image. You can see the app.py for both images below:
master/app.py
...ANSWER
Answered 2020-Apr-08 at 12:02The problem could be having same label app: myapp
for both master and slave. Change the label to app: master
for master deployment and service and app: slave
for slave deployment and service.

QUESTION
I am running a HashiCorp Vault stateless set in K8s with 3 pods on three nodes.
After deployment I manually unseal Vault. Vault then stays unsealed all the time.
The problem is when one of the nodes is restarted, the Vault pod restarts in unsealed mode. Is there any way to automatically unseal the Vault node by server-server-communication with one of the already unsealed pods?
I do not want to have to unseal the Vault pods manually when my Kubernetes environment gets updated and all nodes get restarted (rolling update - one by one).
I also do not want to store the unseal keys in a K8s secret or even a file as this makes encryption of my secrets useless.
This is my yaml:
...ANSWER
Answered 2019-Apr-02 at 06:59After some more digging I learned, what I want is impossible. Whenever a Vault instance is restarted it will be unsealed first and there is no way to unseal it automatically using Vault-own techniques.
You can find a lot of "vault-unsealer" implementations in GitHub and Docker store which try to fill this gap by regularly checking the Vault pods state and unsealing it if necessary.
It is suggested to use an K8s readinessprobe to avoid that services access a sealed Vault pod.
As there is no official "vault-unsealer" image, the public implementations must be used with caution. I ended up writing my own "vault-unsealer" to avoid security flaws and licensing problems.
My solution is a sidecar-container with each Vault pod. The unseal keys first have to be entered once manually with kubectl exec ...
at one sidecar.
The sidecars regularly check all Vault pods and communicate the unseal keys to the other sidecar if sealed. If a sidecar receives unseal keys, they are stored in memory and are used to unseal its own Vault instance.
kubect aply -f vault.yaml
-> vault-0 startingkubectl exec vault-0 -c sidecar ...
to enter unseal keys -> vault-0 sidecar unseals vault-0 and is ready- vault-1 starting
- vault-0 sidecar detects vault-1 unsealed and calls the vault-1 sidecar to transmit the unseal keys. -> vault-1 sidecar unseals vault-0 and is ready
- and so on...

You were trying to find black contours on a white background, which is opposite of OpenCV documentation. This was solved using THRESH_BINARY_INV flag instead of THRESH_BINARY.
Due to the numbers not being connected, a full contour for the number couldn't be found. So I tried some morphological operations. Following are the steps:
