Am I the only one who looked at this and thought: why not buy three decent sized monitors and be able to actually read the agent chat at an ergonomic angle and height?

How are you training engineers and non-engineers on how to use these tools to get ROI? How do you measure ROI?

I use Firebase🔥 Firebase starts getting painful when your data gets relational. So, what’s one reason I should switch to Supabase?

If you’re using Vercel might wanna consider @neondatabase - it has DBs that spin up with new branches which is super cool

Weekends mostly. I work most days but rarely late. I prefer 7 days of moderate pace over 5 of crazy pace

"code that makes money is predominantly not fun to write" I disagree, I've had a lot of fun writing code that makes money. I've: 1. Built AI, before the current AI hype - it made money, paid my salary and was a lot of fun. 2. Built low-latency financial software - it made money, paid my salary and I had fun optimising for low-latency and learning about finance. 3. Built software that controls real-world devices, in this case a whole railway. Seeing your software control something in the physical world is a lot of fun. Sure I've also written some very boring code professionally, but it's not all boring and it doesn't have to be.

I remember creating software for Grocery Outlet store owners and it was so cool (and sometimes humbling) to see how it worked (or didn’t work) at my local store when I talked with store owners. I’ve also had a ton of fun making software that basically had no users 🤷

You need to hide API keys. Where are you putting them?💀 A. Environment variables B. Secret manager C. Server-side config D. GitHub repo

I mean no, but I bet you somewhere someone is doing this 🤷 😅
Has anyone ever actually challenged a decision made by Claude Code or Codex while coding? Like, the AI suggests a way to do something and you just go: “No, I think there’s a better way.” Curious how often people actually push back on their AI coding tools.

I like writing for nerds but increasingly, I like writing for vibe coding founders. This year I've worked on 3 different vibe-coded apps and have been genuinely impressed with what I've seen. Most of them could've saved a lot of headache, pain and monies if they followed the instructions below... brianjenney.medium.com/the-v…

One question genuinely scares me about the software industry Where do all the 40+ year-old software engineers go? You see thousands of young developers entering the industry, but rarely hear about engineers doing the same work at 40. Do they become managers? Switch careers? Get laid off? What’s the actual career path?

Most software engineers have no idea how to make maintainable software, with or without AI. Most for-hire SWEs hop jobs every 1.5-2 years because this is the only reliable way to get a raise, so they never have to deal with consequences of their own decisions. They change 7-8 jobs in 10 years, and then never have to think about 5 years in the future. I had a privilege of maintaining same set of projects for 5+ years, and I know how it is to meet your own temporary hacks 4 years down the road. How many of you can say the same?

Tbh I kinda regret job hopping so much but it was partly out of necessity and partly strategic. Staying 4 years at one org did teach me a lot about my poor architectural choices 😅

I'm going to teach a bunch of business owners how to build and deploy a website. I do NOT want them learning to code or accessing Git. What's the simplest platform to launch a site? To me, it's Vercel. Render is pretty simple too. Any normie-friendly platforms I should use instead?

Given we don’t write code anymore… why are we still dealing with TypeScript and transpilation? Models can write perfect JS in less tokens.

I am in a vibed code base built in JS with no types using Opus to refactor it and types would have saved a LOT of bugs and regressions. Also it's much easier to integrate types from ORMs like Prisma so you have type-safety from end to end. I was actually a bit surprised tbh
