AWS Lambda For The Impatient Part 3

We completed Part 2 of our tutorial on AWS Lambda by calling our Lambda function through an authenticated HTTP endpoint, aided by Postman and leveraging IAM security. In this third and final part, we do the same, only this time programmatically, with the aid of Perl and the Paws module.

Introducing Paws

Paws is a namespace rather than a module, that encompasses a plethora of sub-modules, which aim to, and actually succeed, in achieving the unprecedented:

to provide a unified programming interface to all accessible through APIs Amazon hosted services, be it Amazon Simple Queue Service, Amazon Simple Notification Service, EC2, DynamoDB

or as in this case, AWS Lambda.
We're going to consider Paws in action from two perspectives, assuming a user and assuming a role.

Open Source Is Not Just About Software

It's about infrastructure as well, something that although not attracting the limelight, is as important as the open source software it hosts. Today the stewards of the largest open source registries in the world have issued an open letter demanding urgent reform in how open source infrastructure is funded, maintained, and operated. https://www.i-programmer.info/news/136-open-source/18334-open-source-is-not-just-about-software.html

Europe Gets Its Own LLM

EuroLLM is a fully open-sourced large language model made in Europe and built to support all twenty-four official EU languages. While several European states have separately produced their own LLMs, such as Greece's "Meltemi" or the recent offering from Switzerland "Apertus", there was no solution that catered for the languages of all 24 states belonging to the EU block. The time has come for this status to change with the appearance of EuroLLM, a foundational model that supports them all. https://www.i-programmer.info/news/105-artificial-intelligence/18448-europe-gets-its-own-llm.html

The PaSh Project gives your POSIX script superpowers by utilizing parallelization in order to speed up execution times.

The PaSh Project gives your POSIX script superpowers by utilizing parallelization in order to speed up execution times. This leads to faster results for data scientists, engineers, biologists, economists, administrators, and programmers. I remember the time when the saying was "Learn Perl so you don't have to learn the Shell and its hundreds of utilities". Fast forward some decades and the use of shell scripts still has not been eradicated. On the contrary, their use has increased due to the rise of containers, VM's, administering the cloud, and Linux itself. This also serves as a lesson to those who are quick to denounce technologies as 'dead'. There's a time where a new use case revitalizes an old technology. So what is meant by "Unix philosophy"? full article on i-programmer: https://www.i-programmer.info/news/90-tools/14990-the-pash-project-advancing-the-unix-philosophy-one-step-further.html
