You MUST Review AI-generated Code — Vishnu's Pages A cautionary tale about the importance of reviewing AI-generated code to avoid potential pitfalls.

You must review AI-generated code. Your AI tool can quickly turn from a PhD-level developer to a kindergarten-level monkey, without you even noticing. Review it before committing: iamvishnu.com/posts/you-mu...

Writing a To-Do App in 2027 — Vishnu's Pages Imagining what software engineering will look like in 2027, with a fictional codebase for a simple to-do app built in plain English language, using the new paradigm of Agent Engineering

I am almost convinced by recent OpenClaw and Moltbook developments that by 2027 we will start writing software in plain English, expanding on a new discipline called "Agent Engineering": iamvishnu.com/posts/todo-a...

The Ridiculous Engineering Of The World's Most Important Machine YouTube video by Veritasium

Absolute engineering marvel. The most advanced machine the humanity has ever made.

An excellent @veritasium.bsky.social video on ASML EUV machine that manufactures processors that sits on almost every mobile device today: www.youtube.com/watch?v=MiUH...

My Two Predictions for AI in 2026 (and they're Bad) — Vishnu's Pages In 2026, people will be forced to add disclaimers for human-generated content, and AI will be used everywhere for no apparent reason.

Ah need to catch up. Still on day 8. I thought the switch to 12 days from 25 days this time will be easier, but a linear interpolation applies here also - it gets harder in the middle as always.

FINALLY I've completed "Laboratories" - Day 7 after several tries. I tried recursion on Part 2, but missed to cache the results - Advent of Code 2025 #AdventOfCode adventofcode.com/2025/day/7

Solution in Kotlin: github.com/vishnuharida...

Every assumption about Part 2 was wrong I think. If the operators row had padding whitespaces then we could simply do a reverse traversal picking the numbers from each row, combining them, and operating on them as soon as we encounter an operator.

I've completed "Trash Compactor" - Day 6 - Advent of Code 2025 #AdventOfCode adventofcode.com/2025/day/6

Part 2 was a little tricky though. Solution in Kotlin: github.com/vishnuharida...

I've completed "Cafeteria" - Day 5 - Advent of Code 2025 #AdventOfCode adventofcode.com/2025/day/5

Solution: github.com/vishnuharida...

Stuck at Part 2 with OOM error, thanks @notajocke.bsky.social for the idea of merging the ranges first before processing.

Tried `list.each { toList() }.flatten().distinct().count()` but got OOM error 😆 Thanks for the idea of merging the ranges first.

Day 4 was easy! Advent of Code 2025 #AdventOfCode adventofcode.com/2025/day/4

Solution in Kotlin: github.com/vishnuharida...

Great so far, but stuck at D03P02

Here's my solution in Kotlin: github.com/vishnuharida...

I just completed "Gift Shop" - Day 2 - Advent of Code 2025 #AdventOfCode adventofcode.com/2025/day/2

On Storing TOTP in Password Managers — Vishnu's Pages My argument is that storing TOTP in password managers undermines the very essence of two-factor authentication (2FA), and is still '1FA' in disguise.

My argument is that the practice of storing TOTP in the password manager app undermines the very essence of two-factor authentication (2FA) and is essentially "1FA" in disguise.

iamvishnu.com/posts/totp-i...

Putting both the password and TOTP in the same password manager is not 2FA, that's still 1FA in my opinion - much like locking a box and hiding the key under the same box.

UTF-8 is a Brilliant Design — Vishnu's Pages Exploring the brilliant design of UTF-8 encoding system that represents millions of characters while being backward compatible with ASCII

UTF-8 is a brilliant design — it can represent millions of characters from different languages and scripts, and still be backward compatible with old systems that used ASCII.
