India’s defence sector stocks became one of the most discussed investment themes of 2022-2024. The government’s push for defence indigenisation (the “Atmanirbhar Bharat” push in defence procurement) drove significant investor attention toward HAL (Hindustan Aeronautics Limited), BEL (Bharat Electronics Limited), and Cochin Shipyard. All three saw dramatic stock price appreciation. Here is what the underlying businesses actually look like and whether the valuations are justified. The Policy Backdrop India spends approximately USD 70-80 billion annually on defence - one of the largest defence budgets globally. Historically, a majority of capital expenditure equipment was imported. The government’s goal is to shift 60-65% of defence procurement to domestic sources by 2025-2027. ...

Most engineers monitor their services after they break. A small set of Prometheus metrics and alert patterns reliably signal problems 10-30 minutes before they become outages.

Most Indian investors have 100% of their financial assets in Indian rupees. This is not inherently wrong - you earn in INR, spend in INR, and your liabilities are in INR. But it creates a specific risk: if the Indian economy underperforms over a 10-15 year period (as has happened in multiple countries), 100% domestic equity exposure can deliver poor real returns. The question is not whether to have USD exposure, but how much is optimal for an Indian investor. ...

Azure has grown faster than AWS for six consecutive quarters. The Microsoft bundling strategy, enterprise sales relationships, and OpenAI partnership explain why.

Most Flutter apps feel slightly off compared to native iOS and Android apps. The gap is not inevitable - it comes from specific, fixable patterns in how Flutter renders and handles platform conventions.

A Rs 5,000 monthly SIP can reach Rs 1 crore. The question is how long it takes and what return rate is required. The answer shows why the most important investment decision you make is not which fund to choose, but when to start. The Math at Different Return Rates At a monthly SIP of Rs 5,000, here is the time required to accumulate Rs 1 crore at different annual return rates: ...

A real migration story: taking a Python data processing service that needed 8 workers to handle load, rewriting the core in Rust, and running it on a single thread with better performance.

There is a well-documented gap between what a mutual fund returns and what the average investor in that fund actually earns. In India, mutual fund inflow data consistently shows that retail investors pour money into funds after strong performance and withdraw after corrections - the textbook definition of buying high and selling low. This gap between fund return and investor return can be 3-5% annually, which over 20 years represents a massive wealth destruction. ...

India VIX (India Volatility Index) is calculated by NSE based on the implied volatility of Nifty 50 options. It is often called the “fear gauge” because it spikes when markets are uncertain and falls when markets are calm. Understanding what VIX actually measures and what it predicts - and what it does not predict - is useful for every investor, even those who never trade options. What India VIX Measures India VIX measures the market’s expectation of Nifty 50 volatility over the next 30 days, annualised. It does not measure current volatility - it measures anticipated future volatility as priced into options. ...

Ollama made running large language models locally as simple as running a Docker container. The implications for privacy, cost, and developer workflows are significant.

The Nifty IT Index tracks 10 of India’s largest IT services companies: TCS, Infosys, HCL Technologies, Wipro, Tech Mahindra, LTIMindtree, Mphasis, Coforge, Persistent Systems, and L&T Technology Services (actual constituents may vary with index revisions). For investors already holding a Nifty 50 or Nifty 500 index fund, the question is whether adding a separate IT sector ETF or index fund makes sense. What the Nifty IT Index Actually Measures Indian IT is a specific business model: outsourced services delivery to US and European clients. The revenue is USD-denominated, the costs are INR-denominated, and the business is driven by technology spending budgets at global corporations. ...

The npm ecosystem has had repeated, high-profile supply chain attacks. These are the patterns and packages that have caused the most damage, and how to audit your dependencies.

Every year, Rs 1.5 lakh invested in Section 80C instruments is one of India’s most widely discussed investment decisions. ELSS (Equity Linked Savings Scheme) and PPF (Public Provident Fund) are the two most common choices. They are structurally very different: ELSS is market-linked and has a 3-year lock-in; PPF is government-backed and has a 15-year lock-in with quarterly interest rate revisions. Which one wins over 15 years is not a simple question. ...

Spanner uses TrueTime - atomic clocks and GPS receivers in every datacenter - to achieve globally consistent reads without distributed locks. The architecture is worth understanding.

Every mutual fund in India is required to publish a monthly factsheet. These documents are freely available on the AMC’s website and on AMFI’s portal. Most investors glance at the 1-year and 3-year return numbers, check whether their fund is green, and close the document. This is the wrong way to use a factsheet. What a Factsheet Contains A standard factsheet for an equity mutual fund includes: Fund performance (absolute returns for standard periods) Benchmark performance comparison Portfolio composition (top holdings, sector allocation) Risk metrics (standard deviation, beta, Sharpe ratio, Sortino ratio) Portfolio statistics (P/E, P/B of portfolio, number of holdings) Fund manager details AUM and expense ratio (TER) Investment style box or market cap allocation Section 1: Performance Data - What to Look For The performance table shows returns for 1 month, 3 months, 6 months, 1 year, 3 years, 5 years, and since inception. ...

Deno 3 dropped the ideological baggage that limited earlier versions. npm compatibility, a standard library that works, and a genuinely different approach to deployment make it competitive.

Most investors know roughly how mutual fund taxes work but are surprised by the exact numbers at redemption. Exit loads reduce the amount you receive before taxes are calculated. Capital gains taxes apply on the gain portion. The interaction between exit load timing, holding period, and fund category determines your actual take-home. This is the complete reference. Equity Mutual Funds Large Cap, Flexi Cap, Mid Cap, Small Cap, ELSS, Multi Cap, Thematic Exit Load (most funds): ...

useEffect and useState misuse are the leading causes of performance problems in React applications. Most engineers learn the API without learning the footguns.

OpenTelemetry has stabilized across traces, metrics, and logs. The vendor lock-in problem it solves is real, and the integration path is now practical for most teams.

A Systematic Withdrawal Plan (SWP) is the mirror image of an SIP. Instead of investing a fixed amount monthly, you withdraw a fixed amount monthly from your mutual fund corpus. The math of SWPs has a dangerous asymmetry that most retirement planning discussions in India do not adequately cover: sequence of returns risk. What Sequence of Returns Risk Means Two investors each earn 12% average annual returns over 20 years. Investor A earns good returns early and bad returns later. Investor B earns bad returns early and good returns later. If both are accumulating, they end with the same corpus. If both are withdrawing, Investor B runs out of money much sooner. ...
