rpc | Very simple python rabbitmq/pika rpc library

For some reason, I can't use the Flutterfire CLI to configure an ios app on firebase. I've done this before but this time I'm gettings this error

Am starting off in blockchain development using the book Mastering Blockchain - A deep dive into distributed ledgers, consensus protocols, smart contracts, DApps, cryptocurrencies, Ethereum,

Am using WSL with geth version 1.10.9.

I have a frustrating issue with the Google Cloud Translate API.

I set up correctly the restriction of the key to some domains including *.example.com/ * (without blank space at the end)

I launch the script on the URL https://www.example.com/translate and i have the following message :

I'm building a staking function and hitting the following error after giving permission to access my token:

"MetaMask - RPC Error: Cannot set properties of undefined (setting 'loadingDefaults')"

Staking function Solidity contract:

I am making an NFT marketplace. When I deployed my contract on the Mumbai-testnet. The createToken function might work cause it brings up the Metamask for the Gas Fee but after that, the Error occurs something regarding the ONWNERSHIP. (Error image and text is present below.)

STEPS which I follow

1. npm hardhat node
2. npm run dev
3. Selecting the Creating Page.
4. Enter all the details.
5. Click on Create an Asset which calls the createToken function.

then the error occurs.

Here is my NFT contract

I'd like connect to Delta using JDBC and would like to run the Spark Thrift Server (STS) in local mode to kick the tyres.

I start STS using the following command:

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:

I'm trying to write a simple Solana Program using Rust/Anchor which uses a PDA, but I get a CPI error when I try to invoke it, even though there's no CPI happening (maybe the PDA account initialization?).

Here is the Program code:

I am trying to implement Google Sign-In in Vaadin 21 application + Spring Security using available tutorial for Vaadin 14.
