TX-02 Berkeley Monoβ„’ Typeface A love letter to the golden era of computing.

Bought the Berkeley mono font for the terminal and Cursor.

Pleasantly surprised by how much more enjoyable those are now πŸ€—

Ligatures make code more scannable and readable, too.

Would recommend.

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

Programming is a serious profession.

Teachable is forcing a price hike again.

Seriously tempted to make a $0/month +$5 per student course hosting saas.

ISP lookup ISP lookup shows your IPv4 and IPv6 addresses and their internet service providers. You can also enter an IP or domain name to find their ISPs.

I needed a logo for isplookup.com, but didn't want to spend more than 5 minutes. Found icon.kitchen and made one in 2 πŸ₯°

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?

21.05.2025 08:20 πŸ‘ 1 πŸ” 0 πŸ’¬ 1 πŸ“Œ 0

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.

21.05.2025 07:51 πŸ‘ 1 πŸ” 0 πŸ’¬ 0 πŸ“Œ 0

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.

21.05.2025 07:41 πŸ‘ 1 πŸ” 0 πŸ’¬ 1 πŸ“Œ 0

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.

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

21.05.2025 07:37 πŸ‘ 1 πŸ” 0 πŸ’¬ 1 πŸ“Œ 0

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.

21.05.2025 07:37 πŸ‘ 1 πŸ” 0 πŸ’¬ 1 πŸ“Œ 0

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.

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

21.05.2025 07:28 πŸ‘ 0 πŸ” 0 πŸ’¬ 0 πŸ“Œ 0

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

21.05.2025 06:54 πŸ‘ 1 πŸ” 0 πŸ’¬ 2 πŸ“Œ 0

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

21.05.2025 06:51 πŸ‘ 1 πŸ” 0 πŸ’¬ 1 πŸ“Œ 0

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.

How so?

20.05.2025 18:58 πŸ‘ 1 πŸ” 0 πŸ’¬ 1 πŸ“Œ 0

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.

Looking for a side project?

Subtitlewiki . com just dropped.

Find popular shows / movies. Generate perfectly synced subtitles in all languages using better AI than what’s currently out there. Offer for free and show 2 ads per page.

Differentiate by quality, not quantity.

I was away for 2 weeks.

What’s the meta now?

Which models for planning and coding?
