When the clock on MAC OSX goes off

To sync your macOS clock and prevent it from drifting after sleep cycles, follow these steps:

- Run this command to sync time:

sudo sntp -sS time.apple.com

- Go to System Settings > Date & Time and turn off "Set time and date automatically."

- Remove the current time settings:

sudo rm /var/db/timed/com.apple.timed.plist

- Reboot the Mac.

- After reboot, turn on "Set time and date automatically" in System Settings > Date & Time. This should ensure your clock remains accurate.

Use specific keys for git commands

export GIT_SSH_COMMAND="ssh -i ~/.ssh/my.key"

Minimal kubernetes pods log shipping with fluent-bit

I just released how to ship kubernetes cluster pod logs to Amazon Simple Storage Service (AWS S3) using fluent-bit. Platform engineers should do their best to keep cloud independence. This setup will work for Azure AKS, Google GKE and Amazon EKS. The choice for S3 is just a pick and not a preference. Google Cloud Storage (GCS) or Azure Blob Storage (ABS) will do the job as well (just check fluent-bit docs and adapt the code below for your choice).

Print the content of all zipped files with names containing a regex

Sharing code without using git

Sometimes you do not want to commit to git for security reasons and yet you want to test your code somewhere else.
Run the below from your local copy of the git repository:

rsync -av --exclude-from='.gitignore' --exclude='.git' . ~/Downloads/my-repo-copy
cd ~/Downloads/my-repo-copy
zip -r ~/Downloads/my-repo-copy.zip ./

Copy the content to the remote location and run the below:

mkdir my-repo
mv my-repo-copy.zip my-repo/
cd my-repo
unzip my-repo-copy.zip
rm my-repo-copy.zip
