• Kling – impressive realism and motion

• Pika – fast and simple video creation for social media

• Higgsfield – interesting tools for AI storytelling workflows

Each platform has different strengths depending on the type of content you want to create.

Why choosing the right AI tools is harder than learning AI

I’ve been testing many AI tools in real workflows over the past few months and noticed something interesting.

The biggest challenge with AI today isn’t learning it — it’s choosing the right tools.

There are hundreds of AI apps available, and many people end up trying too many tools without actually integrating any into their workflow.

So I put together a practical guide covering AI tools that genuinely help in everyday work — especially for students, developers, and creators.

If you're trying to figure out where to start with AI, this may help.

Install Free SSL Certificates with Multi-Domain Support (Nginx/HTTPD)

Deep R G — Sat, 29 Mar 2025 08:23:27 +0000

Recently I had to install SSL certs and came across concept of Multi Domain (SANs) and it made life so easy. Hence I documented the whole process here in this article
Basically we we put [alt_names] in openssl.cnf:

[ alt_names ]
DNS.1 = example.com
DNS.2 = www.example.com
DNS.3 = api.example.com

And then generate CSR:

openssl req -new -nodes -out example.csr -newkey rsa:2048 -keyout example.key -config openssl.cnf
