Polars runs 5-50x faster than pandas, uses a fraction of the memory, and has an API that is strictly better once you spend a day with it.

Every year, a subset of investors reviews their mutual fund portfolio, finds that a different fund has performed better over the past 12-18 months, and switches. The logic seems sound: why hold a second-best fund when you can hold the best? The math says this approach is almost always wrong. The Three Costs of Switching When you redeem a mutual fund before certain holding periods and reinvest in another, you face three simultaneous costs: ...

Vercel runs a textbook developer-led growth playbook: get developers hooked for free, then bill their employers when the project goes to production.

In 2021, AMCs launched a wave of thematic funds around technology, digital innovation, and consumption. By 2022, most of these funds were sitting on negative or single-digit returns. In 2023-24, infrastructure, defence, and manufacturing thematic funds dominated NFO launches. The pattern is not coincidence - it is how the fund distribution business works. How AMCs Decide When to Launch AMCs do not launch thematic funds when they believe the theme is undervalued. They launch when they believe the theme will attract investor money. These are different things. Investors are attracted to recent performance. A sector that has doubled in two years gets covered in financial media, generates social media buzz, and fills distributors’ inboxes with inquiries. That is when an AMC files an NFO with SEBI. ...

The number of Indian investors buying US stocks directly has grown significantly in the last five years. Three platforms dominate this space: Vested Finance, INDmoney, and Winvesta. Each has a different fee structure, and the difference can meaningfully affect your actual returns, especially when you account for the forex spread on every remittance. The LRS Framework First Before comparing platforms, you need to understand that all three work under the Liberalised Remittance Scheme (LRS). FEMA allows Indian residents to remit up to USD 2,50,000 per financial year for permitted capital account transactions, including buying foreign equity. ...

Turning off strict mode in TypeScript gives you the false comfort of a type system while keeping all the runtime bugs it was supposed to prevent.

Parag Parikh Flexi Cap Fund is a domestic mutual fund that buys shares in Alphabet (Google’s parent) and Meta. For most investors accustomed to Indian AMCs sticking to BSE/NSE-listed stocks, this raises an obvious question: how does a regulated Indian mutual fund own US stocks, and why would the fund manager choose to do it? The Regulatory Framework SEBI allows Indian mutual funds to invest in overseas securities, but there is a cap. Each AMC has an overseas investment limit, and the industry-wide ceiling has historically been USD 7 billion. This ceiling became a real constraint for Parag Parikh in 2022, when SEBI paused fresh overseas investments after the industry collectively hit the limit. ...

JSONB plus the pg_jsonschema and pg_vectorize extensions give you everything MongoDB offers, with the reliability of a 30-year-old database engine.

In a field dominated by American hyperscalers, a Paris-based company with fewer than 200 employees has become a genuine alternative to OpenAI and Anthropic. Mistral AI is not an underdog story. It is a case study in technical focus, strategic positioning, and knowing exactly which battles to fight. Starting From Exceptional Talent Mistral was founded in April 2023 by three people: Arthur Mensch from DeepMind, Guillaume Lample from Meta AI, and Timothee Lacroix, also from Meta. All three worked on foundational LLM research. Lample co-authored the LLaMA paper. These were not business people who hired researchers. They were researchers who decided to build a company. ...

Unlike large caps, active mid-cap managers have historically beaten the Nifty Midcap 150 index more often. But the margin is narrowing and the best performers are not who you think.

Systematic Withdrawal Plans let you draw a fixed monthly income from your mutual fund corpus. The tax efficiency, sequence of returns management, and fund selection make SWP more complex than it appears.

Dividend yield stocks are considered defensive. NSE data across three major bear markets shows they lose less than the index but still lose significantly. The real numbers challenge the “safety” narrative.

Flexi cap funds are sold as dynamic allocation across market caps. Most of them are effectively large-cap funds with a 20% mid-cap tilt. The data shows why this matters for your portfolio construction.

Your CIBIL score is 780 and your loan application still came back rejected. This is more common than you think, and it is almost never explained clearly by the bank. Here is the complete list of why this happens and what you can actually do about it. Credit Score Is One Input, Not the Decision Banks do not approve loans based on credit score alone. The credit score tells them how reliably you have repaid debt in the past. It does not tell them whether you can repay this specific loan right now. ...

Sector funds attract investors after their best years and see outflows after their worst. AMFI data on sector fund flows vs returns shows investors consistently buy high and sell low.

Bitcoin is legal to hold in India but taxed punitively at 30% with no loss offset allowed. The real question is not whether to own it but how much, and how to account for its actual risk profile.

All three track the same index but deliver different actual returns. Tracking error and tracking difference are the metrics that matter - and UTI consistently leads.

Grey market premiums are unregulated, opinion-based, and have correctly predicted strong listing gains roughly as often as a coin flip. The data on GMP accuracy is damning.

You can solve hard LeetCode problems and still bomb interviews. The game has shifted, and most engineers have not noticed.
