Doctors are not asking for integration of alternative medicine into the standard of care. Patients are not asking for integration of alternative medicine into the standard of care. The public is not asking for integration of alternative medicine into the standard of care. The only people asking for integrative medicine are alternative medicine practitioners, their promoters and sympathizers for survival and business opportunities. The only way alternative medicine can survive into the distant future is by integration into standard medical care and these quacks know it. Don't fall for this nonsense.

The AI Engineering community is getting stronger every week!

Today, we had an amazing audience of software engineers looking to transition to AI.

I am honoured to be a part of their journey.

Cheers!

AI Engineering: 1M context windows

Should we fill the context window of an LLM with 1 million tokens?

This is the needle-in-a-haystack problem.

[Gaurav Sen @gkcs_]

How to write effective Claude Skills.

1. Add triggers (when should a skill fire) to the skill description.

2. Build a gotchas list. "This field is @request_id in the gateway and trace_id in billing. Same value."

3. Use the filesystem for progressive disclosure. Skill md -> references.

4. Give it scripts. Helper functions to avoid writing boilerplate.

5. Don't state the obvious. Claude will use code and search when needed. You needn't make everything explicit.

Engineers building agent workflows can go deeper on skills, MCP, and Claude Code at https://t.co/lsqvTnoxvE.

Cheers!

Should you learn ML before starting with AI?

[Gaurav Sen @gkcs_]

Everyone's using AI. And yet, almost no one trusts it.

[Gaurav Sen @gkcs_]

Valuable lessons by Karthik Ramgopal (Distinguished Engineer at LinkedIn).

1. AI should only be used for tasks that can be done manually.

If you cannot do the task yourself, you can't validate, guardrail, or eval the output.

To make a reliable system, we need AI output to mimic human output.

2. Developer productivity is up. Getting a job is difficult.

The engineers most at risk are those who treat AI as a black box.

They skip the fundamentals (context engineering, retrieval, evals) and lose the ability to judge whether the work is right or wrong.

Strong fundamentals and knowing how to harness AI are essential. I really feel like plugging in my cohort here, but I will resist the temptation :p

3. Both juniors and seniors are learning AI together. We are all on the same boat.

Juniors entering the workforce are AI-native by default. Seniors carry years of real-world judgment but are ossified into old habits.

Drop the ego. Let the learning flow.

1. Transformers
1.1 Tokens
1.2 Vectors
1.3 Attention

2. Retrieval Augmented Generation
2.1 Chunking
2.2 Vector Databases
2.3 Query Rewriting
2.4 Chunk reranking

3. Agents
3.1 Short-term and long-term memory
3.2 Tool use
3.3 MCP
3.4 Orchestration

4. Evals
4.1 Manual Evals
4.2 LLM as a Judge

On the 25th of March 2026, Discord had a global voice outage.

This is a summary of it's incident report.

[Gaurav Sen @gkcs_]

In an interview, you don't rise to the occasion. You fall to the level of your practice.

[Gaurav Sen @gkcs_]

@st4ayh4rd Do it and then let me know :)
