Building AI Browser Agents with Browser Use and Playwright
Artificial intelligence is changing how developers interact with the web. Traditional browser automation was originally designed around predefined scripts, rigid workflows, and predictable user actions. Developers manually wrote automation logic that followed exact selectors, buttons, and navigation sequences. While effective, these systems often broke whenever websites changed their layouts [...]
The New Software Stack: AI + GitHub + Cloud

AWS CloudFormation Deletion Policy

Deleting a stack on CloudFormation also removes all the provisioned resources in it. In some cases, you want some resources to be retained even after deleting its stack. The good thing is that you can do this by defining its DeletionPolicy. This is pretty straightforward - you just need to define DeletionPolicy with Retain value and for the resources that support snapshot, (like RDS databases) you can set Snapshot as its value. With DeletionPolicy: [...]

AWS CloudFormation StackSets and Nested Stacks

AWS CloudFormation lets you model and provision resources for your environment using programming language, leveraging the concept of Infrastructure as Code (IaC). You don’t need to manually create all of your resources one by one, CloudFormation will do this for you. All resources are defined on the AWS CloudFormation template. This means that this AWS environment can be reliably and easily reproduced since everything is declared on a template. For example, creating a new [...]

Amazon S3 Access Points

Managing access to your S3 buckets should be pretty easy using Amazon S3’s bucket policy. But as the number of your users and data grows, this easily becomes a complicated task. Provisioning access policies (who and where to access these objects) to these users could be a messy thing to do. AWS added this feature called Access Points on S3 to resolve this current problem. Access Points can simplify things in terms of provisioning [...]
