Why is this hard?

news.ycombinator.com Unknown 2025-11-01 10:47:06

Every decision we make as developers is a tradeoff. We choose to do it because we believe that it holds benefit for what we are trying to accomplish. However, it is generally also a liability. The new code we are adding will need to be maintained, following new processes takes time, keeping infrastructure up-to-date and secure requires regular effort, etc. We are in an eternal battle to build what we need to build without being overwhelmed by these forces. If we're going to stave off that inevit

Writing Micro Compiler in OCaml (2014)

news.ycombinator.com Dmitry Geurkov 2025-10-31 10:00:32

TL;DR Writing micro compiler in OCaml At one point or another every single software developer in the world comes to a realization in his career when the time is ripe and it’s time to write your own super cool programming language. However the subject of creating your own programming language with an compiler is quite a complex one and can’t be tackled without some pre-research.

Vibe Debugging: Enterprises' Up and Coming Nightmare

It's 12:45 PM, and my morning has vanished into the black hole of debugging my vibe-coded meme stock valuation site. The monthly growth numbers are spitting out garbage. What should be a steady 3-5% is showing wild swings between -50% and +2000%; the numbers don't add up.

Beyond the Logo: How We're Weaving Full Images Inside QR Codes

news.ycombinator.com Anant Bhasin 2025-11-03 15:43:31

QR codes are everywhere. They’re incredibly functional, connecting our physical and digital worlds with a simple scan. But let's be honest: most of them are an eyesore. The standard black-and-white pixelated square often feels like a necessary evil that disrupts an otherwise beautiful design. The common solution has been to leverage the QR code's built-in error correction to place a logo in the center. While functional, it’s still an overlay—a sticker on top of the data.

AWS CEO says using AI to replace junior staff is 'Dumbest thing I've ever heard'

Amazon Web Services CEO Matt Garman has suggested firing junior workers because AI can do their jobs is "the dumbest thing I've ever heard." Garman made that remark in conversation with AI investor Matthew Berman, during which he talked up AWS’s Kiro AI-assisted coding tool and said he's encountered business leaders who think AI tools "can replace all of our junior people in our company."

Why Did a $10 Billion Startup Let Me Vibe-Code for Them—and Why Did I Love It?

Sitting a few feet away was Simon Last, one of Notion’s three cofounders. He is gangly and shy, an engineer who has relinquished management responsibilities to focus on being a “super IC”—an individual contributor. He stood to shake my hand, and I awkwardly thanked him for letting me vibe-code. Simon returned to his laptop, where he was monitoring an AI as it coded for him. Later, he would tell me that using AI coding apps was like managing a bunch of interns. Since 2022, the Notion app has had

All the opinions expressed in this article and on this website are entirely my own and do not represent my employer in any way. Ever heard about the “Bus factor”? It is a concept that measures the risk of losing all knowledge about a particular thing – a software development project for example – by estimating how many team members could get crushed by a bus before nobody knows how to work on the project anymore. As an example, if 3 people on your team know how to restore a backup of your datab
