@JioCare @JioCare is near the SLA of 48 hours. SIM may not reach within the SLA???

@reliancejio Customer Care at a very low service

[Ramanathan Alagappan இராமநாதன் @alramanathan]

@reliancejio I ordered a Jio SIM on 19-Aug, submitted all the documents digitally and verified them through Aadhaar OTP. However still it shows document verification in progress. I should have walked into store and got a SIM, digital process @JioCare is not working effectively!

We released skillpatch - https://t.co/QyaYnbx1DF, yesterday.

A student used it to create nice notes using my lectures on RLHF.

Now I don't need to create notes either! Feels like I have built my own clone.

Height of irony - I'm working to make myself redundant!

"How to Build and Fine‐Tune a Small Language Model: A Step-by-Step Guide for Beginners, Researchers, and Non-Programmers"

Available at https://t.co/msIjZw2arK

Build your own AI—without a PhD, expensive hardware, or industry-level resources. Whether you’re a beginner, a student, a scientist, or a domain expert, this book shows you how to create, train, fine-tune, and deploy Small Language Models (SLMs) that truly understand your field.

Most AI books explain what models are. This one teaches you to build them. You’ll go from zero to a working GPT-style model, then learn how to fine-tune, align, evaluate, and deploy it for real applications.

All chapters include ready-to-run Google Colab notebooks.

Data scientists
Machine Learning
Artificial intelligence
Software engineers

Non-programmers
Beginners and students

Core concept படிக்கும்போது, அதை real life example ஓட compare பண்ணி படிச்சீங்கன்னா, easyயா புரிஞ்சுக்க முடியும்.

உதாரணத்துக்கு, Python Data Structure (Arrays) படிக்கும்போது,
அது அம்மா மளிகைப் பொருட்கள் வாங்குற வேலையோட compare பண்ணி படிச்சீங்கன்னா, Concept உங்களுக்கு ரொம்ப நல்லா புரியும்.

Concept நல்லா புரிஞ்சிருச்சுன்னா, எந்த problem-க்கும் உங்களால code எழுதுறது கஷ்டமாவே இருக்காது.

SET: (இதுல duplicate இருக்காது)
அம்மா எழுதும் மளிகைப் பொருட்கள் பட்டியல்

DICT: (பொருளும் அதோட அளவும் இருக்கும்)
அம்மாவும் அப்பாவும் சேர்ந்து எழுதும் மளிகை பொருட்களும் மற்றும் அதன் அளவுகளின் பட்டியல்.

TUPLE: (இதை மாற்ற முடியாது)
அப்பா எழுதும் கடைக்காரரிடம் வாங்கிய பொருட்களின் பட்டியல் (Not a Bill)

LIST: (இதை மாற்ற முடியாது)
பொருட்கள் வாங்கிய பின், வீட்டில் இருக்கும் பொருட்களுடன், புது பொருட்களையும் அடுக்கி வைக்கும் பொழுது கிடைக்கும் பட்டியல்

Rajeev Thakkar, CIO of PPFAS has just written a letter to unitholders. Here are some key points:

1. PPFAS hasn't even given FD returns - his response

The only way to guarantee an FD return is to make an FD. Volatility is the reason equities can potentially beat FDs in the first place, not a bug in the system.

2. Why is PPFAS holding so much cash?

Cash peaked near 25% during the 2024 exuberance, when the team was guiding caution. It's down to 14-15% in Flexi Cap now. Thakkar expects single digit levels as more opportunities open up after two years of time correction.

3. Is the underperformance due to its large size?
No. He points to 2007, when he ran a larger drawdown on a PMS book of about ₹100 crore. The current stretch is ordinary for a strategy that buys out of favour names.

4. What about HDFC Bank?
PPFAS holds a basket of 4 private banks. Thakkar says HDFC Bank's recent issues don't carry the scale of past sector frauds and don't threaten the franchise. No change to the outlook on the basket.

5. What about small and midcap valuations?
Nifty 100 trades at 20.8x, Nifty Midcap 150 at 30.7x, Nifty Smallcap 250 at 34.6x, per Screener data as of August 4. Thakkar's point is that smaller doesn't structurally mean higher returns, and he cites the US market as a counterexample.
