@IndiaPostOffice Attaching error message as seen in Google Chrome. Please have a look and fix the issue.

[RKr @rkrgarg]

@IndiaPostOffice The https://t.co/GBvH4deC5Z website is not accessible outside India. This is happening since the past 2 days only. FYI, this has happened before also but was fixed by India Post then.

Kindly fix this ASAP as I can't open the website to place order for stamps.

@IndiaPostOffice Please provide an update. The https://t.co/GBvH4deC5Z website is still not accessible from outside India.

If you have a Gmail account, you must need to read this.

Google's AI now scans your emails and attachments, bank statements, tax files, medical letters, all of it. It turned on by default, and there's a class-action lawsuit over how.

Here are 5 moves to shut it off, the switch is hidden in two places:

🫀 CT Calcium Score – A Simple Test That Can Save Lives

Did you know that heart disease can be present even before symptoms appear?

A CT Coronary Calcium Score (CAC Score) is a quick, non-invasive CT scan that measures calcium deposits in your heart's arteries. It helps identify hidden coronary artery disease and estimates your future risk of heart attack.

Who should consider it?
✅ Adults aged 40–75 years with intermediate cardiovascular risk
✅ People with diabetes, high cholesterol, high blood pressure, smoking history, or a family history of early heart disease (after consulting their doctor)

Calcium Score Interpretation:
🟢 0 – Very low risk
🟡 1–99 – Mild plaque
🟠 100–399 – Moderate plaque
🔴 ≥400 – High risk; needs further evaluation

Remember:
A calcium score of 0 does not guarantee zero risk, but it strongly suggests a very low likelihood of significant calcified coronary artery disease.

❤️ Early detection can help prevent future heart attacks through timely lifestyle changes and appropriate treatment.

OpenAI CEO, Sam Altman:

«You don't need to write prompts anymore.»

In 38 minutes, he explains how to use ChatGPT better than most people do.

He gave this lecture for Stanford students. My friend sent me the recording.

I watched it last night, realizing I was using maybe 15% of what ChatGPT can actually do.

Watch it, then read the guide below on how to build a system that prompts itself.

[Sarah Alam @DrSarahAlam]

So, not all thyroid nodules require surgery or biopsy.
It's important to consult with an endocrinologist who specializes in thyroid disorders to evaluate your specific case, review your tests, and discuss management plan based on your individual circumstances.
THE END. 23/n

🚨 Anthropic just showed a 27-minute workshop on how to actually do prompts for Claude.

Taught by the people who built it.

Free. No registration. No paywall.

I've seen $300 courses that don't cover what they teach in the first 8 minutes.

Watch it and bookmark it now.
