In general we would have tar installed on a kubernetes pod. Sometimes when things are not happening, we can still copy to the container using the following command :-  Copy to container cat local-backup.tar.gz | kubectl exec -i -n cattle-resources-system \ rancher-backup-57c997f8cd-fxlb4 -c rancher-backup -- \ sh -c 'cat > /var/lib/backups/backup.tar.gz' Copying from container  kubectl exec -n cattle-resources-system rancher-backup-84576c498c-lpjh2 \ -c rancher-backup -- cat /var/lib/backups/default-location-recurring-backup-8723b2bd-e272-430e-89f6-14a133f8a417-2026-02-25T03-12-05Z.tar.gz \ > local-backup.tar.gz

When installing qwen code using the following command  curl -fsSL https://qwen-code-assets.oss-cn-hangzhou.aliyuncs.com/installation/install-qwen.sh | bash  it stuck in endless loop. This is due to installer not having permission to the /usr folder. To resolve it # 1. Create the directory for global packages mkdir -p ~/.npm-global # 2. Tell npm to use this new directory npm config set prefix '~/.npm-global' # 3. Open (or create) your shell profile file # If you use Bash (default on many Linux): echo 'export PATH=~/.npm-global/bin:$PATH' >> ~/.bashrc source ~/.bashrc Install gwen  npm install -g @qwen-code/qwen-code@latest And walla! 

In this demo, i am going to import an existing storage called " appjerwo-demo-test " and once i have done that I will create another s3 bucket called " myjerwo-new-bucket-2026 ". To get started, I will need to have to prepare my import s3 template. import-template.yaml AWSTemplateFormatVersion : ' 2010-09-09 ' Description : Import existing S3 bucket Resources :   ImportedAppBucket :   # ← ONLY the resource being imported     Type : AWS::S3::Bucket     DeletionPolicy : Retain   # ← REQUIRED for imports     Properties :       BucketName : appjerwo-demo-test And then I will proceed to run the following command to create import changeset. My stack name is called my-app-stack.    aws cloudformation create-change-set \   --stack-name my-app-stack \   --change-set-name import-bucket \   --change-set-type IMPORT \   --template-body file://import-template.yaml \   --resources-to-import '[{   ...

To deploy to a testnet, let's use this endpoint as my testnet - https://eth-sepolia.g.alchemy.com/v2/xxxxxxxxxxxxxxxxxxxxxxxxx. Please register and create a free account and select all the testnet A nd we also need to set the wallet private keys (please do not share actual private key). This account here must have some $$$$. If you don't have you can use sepolia to send this over to your MetaMask or any other wall.  https://cloud.google.com/application/web3/faucet/ethereum/sepolia Once you have the account you can paste your wallet id to the url above. To get the wallet id, click on "receive" as shown here     Why use google? Others like Alchemy requires atleast some $$$ in your wallet before you can deploy anything.Ensure that we have the followings configurations:-     hardhatOp : {       type : " edr-simulated " ,       chainType : " op " ,     },     sepolia : {       type : " http " ,...

To start off with you need to run "pnpm dlx hardhat --init" Next it will ask you as series of questions, which you can just choose yes. You should be asked to install the following dependencies  You need to install the necessary dependencies using the following command: pnpm add --save-dev "hardhat@^3.1.7" "@nomicfoundation/hardhat-toolbox-viem@^5.0.2" "@nomicfoundation/hardhat-ignition@^3.0.7" "@types/node@^22.8.5" "forge-std@foundry-rs/forge-std#v1.9.4" "typescript@~5.8.0" "viem@^2.43.0" Otherwise you will get weir issue like forge-std missing. And if all goes well, you will get this 

When running the following command  npx hardhat test Error HHE902: There was an error while resolving the import "forge-std/Script.sol" from "./contracts/script/Counter.s.sol": The package "forge-std" is not installed.

When running "npx hardhat test", I ran into this error:- Cannot find package '@nomicfoundation/hardhat-toolbox-viem' imported from /home/nzai/work/ether/hardhat-example/hardhat.config.ts To resolve this npm install --save-dev @nomicfoundation/hardhat-toolbox-viem viem   

  Setup and getting started with kubectl AI. https://github.com/GoogleCloudPlatform/kubectl-ai?tab=readme-ov-file#installation

To get started with Google GenAI SDK key, first you need to create an API key here. https://aistudio.google.com/app/api-keys After that, you can fire up your python env and install  pip install -q -U google-genai Setting up API key in your environment export GOOGLE_API_KEY="your-key-here" And then do a hello work python with the following code:  from google import genai # The client gets the API key from the environment variable `GEMINI_API_KEY`. client = genai . Client () response = client . models . generate_content (     model = " gemini-3-flash-preview " , contents = " Explain how AI works in a few words " ) print ( response . text )

 After de-registering the server, we still have some namespaces, rolebindings, role and pods in the cluster that needs to be clean up. To do that without causing your resource wait indefinite due to finalizer, do the following  curl -O https://raw.githubusercontent.com/rancher/rancher/master/cleanup/user-cluster.sh chmod +x user-cluster.sh   ./user-cluster.sh rancher/rancher-agent:v2.13-head                         If everything runs well, you get this 

I guess this can happen to any version of keda metric api metric server getting the error after upgrade/deployment.  grpc: addrConn.createTransport failed to connect to {Addr: "10.0.224.114:9666", ServerName: "keda-operator.keda.svc.cluster.local:9666", }. Err: connection error: desc = "transport: authentication handshake failed: read tcp 10.244.43.200:60114->10.0.224.114:9666: read: connection reset by peer" The solution, delete a secret call kedaorg-cert in the keda namespace and let keda re-generate by doing a deployment rollout for all keda pods.  Check if the certificate exist  kubectl get secrets -n keda Proceed to delete the certificate  kubectl delete secret kedaorg-certs -n keda Redeploy the instances kubectl rollout restart deployment keda-operator -n keda kubectl rollout restart deployment keda-operator-metrics-apiserver -n keda Right at the end you will see connection is established.
