Actually, I wanted to do this last year, but like a lot of side projects, it kept sitting on the list. I would think about it, open the repo, look at the amount of work, and then convince myself that Hashnode was fine for now. And honestly, Hashnode was fine. The issue was not that Hashnode was bad. https://rishabkumar.com/blog/getting-more-out-of-codex/ Thu, 21 May 2026 21:35:30 +0000 https://rishabkumar.com/blog/getting-more-out-of-codex/ I started using Codex the obvious way: point it at a repo, ask it to make a change, run the tests, and help me clean up the diff. That is still useful. But lately, I’ve been using Codex for a lot more than just code. I use it to help with blog posts, talks, docs, Azure demos, browser testing, research, and random follow-ups that would otherwise sit in my head for too long. https://rishabkumar.com/blog/google-cloud-professional-cloud-security-engineer-study-guide/ Mon, 15 Dec 2025 16:52:10 +0000 https://rishabkumar.com/blog/google-cloud-professional-cloud-security-engineer-study-guide/ Hey everyone!

The job paid the bills, but it wasn’t what I wanted to do long term. I tried staying back after work to study AWS, but most days I was drained. After troubleshooting tickets for 8 hours, my brain was fried. So I made a small shift — I started coming in early. One hour before my shift started, I’d grab a coffee and study. https://rishabkumar.com/notes/gcp-cloud-security/ Sun, 06 Apr 2025 12:12:25 +0000 https://rishabkumar.com/notes/gcp-cloud-security/ Overview The Professional Cloud Security Engineer certification focuses on designing and implementing secure workloads and infrastructure on Google Cloud.

I know I barely passed, as 700 is required passing score and also I barely finished in time, so managing those minutes is essential! https://rishabkumar.com/blog/terraform-lock-hcl-to-gitignore-or-commit/ Sun, 11 Feb 2024 16:34:14 +0000 https://rishabkumar.com/blog/terraform-lock-hcl-to-gitignore-or-commit/ One question that I had in my mind when I first build my IaC(Infrastructure as Code) with Terraform was, what all needs to be included in the .gitignore, especially the .terraform.lock.hcl. So here is the quick answer: Yes, you should commit the .terraform.lock.hcl to your version control (GitHub repository). Let’s first see, what is the .terraform.lock.hcl. According to Hashicorp’s documentation Terraform automatically creates or updates the dependency lock file each time you run the terraform init command. https://rishabkumar.com/blog/github-foundations-certification-exam/ Fri, 19 Jan 2024 15:49:08 +0000 https://rishabkumar.com/blog/github-foundations-certification-exam/ GitHub now has certifications.

The three-way handshake is a fundamental part of TCP. It is a process that is used to establish a connection between two devices before they can exchange data. When a client wants to initiate a connection with a server, it sends a SYN (synchronize) packet to the server. This packet contains a sequence number that is used to keep track of the order of the packets during the transmission. https://rishabkumar.com/_blog/tcp-three-way-handhsake/ Mon, 12 Dec 2022 00:00:00 +0000 https://rishabkumar.com/_blog/tcp-three-way-handhsake/ TCP stands for Transmission Control Protocol.
