A team of AI researchers at Microsoft introduces two novel approaches for enforcing contextual integrity in large language models: PrivacyChecker, an open-source lightweight module that acts as a privacy shield during inference, and CI-CoT + CI-RL, an advanced training method designed to teach models to reason about privacy.

There is a specific kind of restlessness that only developers understand. It's a quiet, persistent itch. A mental "background process" that runs while you're eating, showering, or trying to sleep. I call it the urge to build.

Looking back at my GitHub contribution graphs from the last few years, I see more than just green squares. I see a timeline of my own evolution.

I was chasing that dream many developers have: build a small product, ship it, get users, maybe turn it into a business. Most of those ideas didn't become a successful SaaS.

But that wasn't the point.

The point was that I was building constantly. Learning constantly. Shipping constantly.

And I loved it.

The Indie Hacker Dream

Back in 2020, my contribution graph shows the classic "burst" pattern. I was chasing the indiehacker dream. You know the one: build a SaaS, get to ramen profitability, escape the 9-to-5, tweet about your MRR milestones. I consumed every bootstrapper podcast, every "I made $10K/month" blog post, every ProductHunt launch breakdown.

I was working on a project called Expensely. I spent late nights pouring myself into this "genius" idea: a budgeting app.

Nothing revolutionary. The world didn't need another expense tracker. But I needed to build it.

Looking back now, it was far from genius. But at the time, I was convinced that this was the one.

In 2021, that momentum stayed steady for five months before life (or perhaps reality) intervened. Those green squares represent the fun periods. They represent the thrill of architecting an application, the satisfaction of a passing test suite, and the hope that you're building something that might change your life.

Expensely never became a business. Most side projects don't. But here's what I've come to understand: the outcome wasn't the point.

Even though those projects didn't become the next big SaaS, they were the forge where my skills were sharpened. You don't "waste" time building something that fails. You only waste time when you don't build at all. And I mean this both metaphorically and literally. Humans are meant to create. When we stop creating, we stagnate.

What Building Actually Gives You

When you build something from scratch - when you own every decision from the database schema to the button colors - you learn differently. There's no senior developer to ask. No established patterns to follow. Every problem is yours to solve.

You can use Railway-Oriented Programming if you want to, because who is going to stop you?

Jokes aside, functional programming is very useful. You should learn it.

Through my side projects, I wrestled with authentication, background jobs, payment integrations, deployment pipelines. I made mistakes and spent late nights fixing them. I built features nobody asked for and skipped features everyone needed.

There is one thing side projects can't teach you (unless you get users): dealing with the consequences of your decisions. When you build for yourself, the only person affected by your mistakes is you. When you build for users, every bug, every outage, every poor design choice has real consequences.

By mid 2021, the project had wound down. I was settling into a comfortable routine at my day job, working as a senior engineer at a big corporation. There was no time left for side projects.

The Unexpected Pivot

By 2022, something changed. My contribution graph exploded to over 1,600 commits. But the focus shifted. I wasn't building a product anymore. I was building something more meaningful. The repositories shifted to my tech blog and YouTube projects.

I had discovered content creation.

The urge to build hadn't disappeared. I found a new outlet. Instead of building products for users, I was building educational content for developers. Instead of SaaS metrics, I was tracking video views and newsletter subscribers. To me it was something new, something exciting.

I discovered that while I loved building software, I loved explaining it even more. I transitioned from an aspiring founder to a software engineering educator. At first it was just me writing and recording things I wish someone had explained to me earlier.

Then something interesting happened.

People started reading. Watching. Replying. Asking questions. More people showed up. And then even more.

Today, I get to help thousands of developers around the world improve their careers. It is, without a doubt, the most rewarding work I've ever done.

This is genuinely fulfilling work. When someone messages me saying my content helped them land a job or finally understand a concept they'd struggled with for years, that feeling is hard to describe. I'm doing something meaningful.

And yet.

The Lingering Itch

The urge to build something still remains.

It's not dissatisfaction. It's not that content creation isn't "real" building, it absolutely is. It's a different kind of building, certainly. But this feeling I have is something more fundamental. A part of my brain that wants to work on a fresh project. That wants to solve a problem nobody has asked me to solve. That wants to take an idea from nothing to something.

That's why I have a Hetzner server sitting idle right now. Never know when I might need it. Right? Also, I'm getting a great deal for €3.29/month. Can't argue with that.

I think this urge never fully goes away for people like us. We can channel it, redirect it, find new outlets for it. But it's always there, lingering. And maybe that's okay. Maybe that restlessness is what makes us who we are.

Why You Should Build Too

If you're reading this with your own idea rattling around in your head - some app concept, some tool you wish existed, some problem you think you could solve - I want to tell you something.

Build it.

Not because it will make you rich. Statistically, it won't. Not because it will become the next big thing. It probably won't be that either.

Build it because the person who finishes that project will not be the same person who started it. You will learn things no tutorial can teach. You will develop judgment that only comes from making real decisions with real consequences. You will have stories, opinions, and experiences that set you apart.

The outcome is almost beside the point. The transformation is the product.

Maybe you'll end up with a successful SaaS. Maybe you'll end up with a failed project and a mass of hard-won knowledge. Maybe, like me, you'll end up somewhere you never expected - doing work you couldn't have imagined when you wrote that first line of code.

You won't know until you build.

So open your terminal. Type git init. And start.

Let this be a year of building.

The most popular blogs of Hacker News in 2025

The engine behind the project is the domain-meta.csv CSV on GiHub, a hand-curated list of known personal blogs with author and bio and tag metadata, which Michael uses to separate out personal blog posts from other types of content.

I came top of the rankings in 2023, 2024 and 2025 but I'm listed in third place for all time behind Paul Graham and Brian Krebs.

I dug around in the browser inspector and was delighted to find that the data powering the site is served with open CORS headers, which means you can easily explore it with external services like Datasette Lite.

Here's a convoluted window function query Claude Opus 4.5 wrote for me which, for a given domain, shows where that domain ranked for each year since it first appeared in the dataset:

with yearly_scores as (
  select 
    domain,
    strftime('%Y', date) as year,
    sum(score) as total_score,
    count(distinct date) as days_mentioned
  from "hn-data"
  group by domain, strftime('%Y', date)
),
ranked as (
  select 
    domain,
    year,
    total_score,
    days_mentioned,
    rank() over (partition by year order by total_score desc) as rank
  from yearly_scores
)
select 
  r.year,
  r.total_score,
  r.rank,
  r.days_mentioned
from ranked r
where r.domain = :domain
  and r.year >= (
    select min(strftime('%Y', date)) 
    from "hn-data"
    where domain = :domain
  )
order by r.year desc

(I just noticed that the last and r.year >= ( clause isn't actually needed here.)

My simonwillison.net results show me ranked 3rd in 2022, 30th in 2021 and 85th back in 2007 - though I expect there are many personal blogs from that year which haven't yet been manually added to Michael's list.

Also useful is that every domain gets its own CORS-enabled CSV file with details of the actual Hacker News submitted from that domain, e.g. https://hn-popularity.cdn.refactoringenglish.com/domains/simonwillison.net.csv. Here's that one in Datasette Lite.
