Bought the Berkeley mono font for the terminal and Cursor. Pleasantly surprised by how much more enjoyable those are now 🤗 Ligatures make code more scannable and readable, too. Would recommend. usgraphics.com/products/ber...

Vanity metric, but still kinda exciting that there are only 50k sites with more authority than nslookup.io

The domain name isplookup.com dropped last week, so I made this online tool. It shows your IPv4 and IPv6 addresses and their internet service providers. You can also enter an IP or domain name to find their ISPs. Not as fancy as some startups, but I hope it'll have a tiny impact on many people :)

I was a tech guy in 90's. There was a feeling amongst the older guys that us new breed were idiots because we were only working on the application layer and didn't understand the 1's and 0's. Many of my dads friends believed you shouldn't be able to drive a car unless you knew how to fix it.

Do you see any reason that prevents AI from being incorporated into the process?

110

Ruurtjan @ruurtjan.com · 21/05/2025

It’s very early days, so makes sense that things diverge before they converge. In my experience, AI code assistants are already good enough to significantly speed up my development and show me approaches I didn’t think of myself. We all need to learn how to use it and what it’s good enough at now.

010

Ruurtjan @ruurtjan.com · 21/05/2025

But they’re probably faster? Do code reviews and show them prompts that point out the weakness of their code. They’ll learn faster than the other cohort that way, simply because their iteration cycle is shorter. Encourage that cohort to leverage AI as a learning tool, rather than a code generator.

110

Ruurtjan @ruurtjan.com · 21/05/2025

After each session, see if you can find coding conventions or other opinionated things you can define as prompt rules. Commit them to git so the entire team will prompt AI similarly.

Ruurtjan @ruurtjan.com · 21/05/2025

Working with AI is a skill that devs of any skill level can and should learn.

110

Ruurtjan @ruurtjan.com · 21/05/2025

Start with function signatures and return types, then work through to implementation. Continuously iterate and optionally revert and try again with clearer requirements. When you’ve shown them a couple of times, they’ll understand what to look out for when evaluating the AI responses.

110

Ruurtjan @ruurtjan.com · 21/05/2025

I’d start with working alongside them if you have the time and let them work with ai. Prompt for design options and their tradeoffs. Provide additional non-functional requirements until a decent approach emerges. Then let it summarise and start iterating on implementation.

Ruurtjan @ruurtjan.com · 21/05/2025

It sounded like you’d advise juniors against using AI. Secretly going against the advice of a senior can induce shame.

000

Ruurtjan @ruurtjan.com · 21/05/2025

If used correctly (which you can teach junior devs), AI can be a medior pair programmer and private tutor.

210

Ruurtjan @ruurtjan.com · 21/05/2025

Why don’t you teach them how to leverage AI to accelerate their growth?

110

Ruurtjan @ruurtjan.com · 21/05/2025

Imagine telling them that they can’t look at how others tie their laces because they might do it badly/wrongly. Shame them into painstakingly figuring it out by themselves by trial and error.

100

Ruurtjan @ruurtjan.com · 20/05/2025

I don’t understand why people advise junior developers to avoid using AI. They lack experience, but they’re not stupid. Surely they’ll eventually figure the right design. Besides, reading code and evaluating its quality is a super valuable skill, which you’ll learn much faster with AI.

Where are all the Chromium forks with AI agents? Should be a much better platform for automation for most people.

I’ll be impressed by your AI if it can identify the exact toy set this wheel is part of. So far none could.

Ah, nice :) I’ve had quite a few for just 1 or 2 months and a couple for years. Not much in between.

$7k a month is solid! How long do advertisers typically stay?

How do I check if a logo design isn’t too similar to an existing logo? Any sites that are searchable?

Ruurtjan @ruurtjan.com · 04/03/2025

I feel like we're not there yet. AI needs technical guidance - at least for now. Maybe it'll become more proficient and we can move on to product management. We'll see :)

I learned to slackline. It was very easy. All I did was get on it, take a few steps, fall and try again. 10 min per week for 6 months. Now I tell myself to just start and keep going whenever I need to do something daunting.
