Silmaril (@Silmarildev) is the first self-healing prompt injection defense.

It catches 2x more attacks 10x faster than leading defenses, and retrains continuously to protect your full AI stack, including agents like Claude Code and OpenClaw.

Congrats on the launch, @aumup001 and @EduardoVel36291!

“Aha, that’s so crazy that happened haha we live in a simulation.”

No, you moron. God is real. This is how He taps the glass. Synchronicity. Small winks. Precise hits that land too clean to be random, the names that keep repeating, the doors that open on the day you were ready to quit

You hide behind ‘simulation’ so you never have to admit Someone is actually calling you to do something with your life

"...there is not a fixed amount of wealth in the world. You can make more wealth."

Paul Graham on the Pie Fallacy:

[Aurelius Systems @aureliuslasers]

When you build a facility that employs thousands, you don’t only create jobs.

As our CEO @LaFrogman put it: You raise wages, strengthen local businesses, pay taxes that support services, and create downstream opportunities that impact tens of thousands more.

Last week, @ti_morse brought together five frontier founders leading with that vision, @sdamico, @jasonjoyride, @willob, Michael LaFramboise, and @laurence1allen each building to shift the paradigm of what American industry can be.

America’s strength comes from building things. It’s time to Reindustrialize America.

If you're applying to YC, make your application uncomfortably short.

Partners are reading thousands of apps. They are skimming through all of them. Make their lives easier.

Simple and short. Trust me.

Some of you have never hit this mode on an NYC Saturday night and it shows
