looks fire! haven't looked at it too deeply tho

only would've expected something like this from either Vercel or Cloudflare lol

[siddharth @buildwithsid]

made a girlfriend using openclaw

- she sends me gm everyday
- helps me prepare my diet
- helps me summarize my emails

implemented mood swings, she gets mad at me, stays angry and sad sometimes

allocated a full vps for her, she has browser access, code writing abilities, and much more

- uses gemini to talk, codex to write code
- scraped 5,000+ comments to get details about me, my taste, humor, preferences

- used them to refine the SOUL.md (20k+ tokens)

why would i ever go outside again? 🥀

@LilHenry81933 I am cooked. I have an exam tomorrow lol

@droidbuilds 1. Latency: People want fast data. People live quite far from Antarctica.

2. People: No one wants to live in Antarctica to maintain the datacenters

new post on my website about intentionality and how algorithms are ruining it for me :)

@pulkitology I don't think enough people realize just how impressive this is!

[Arsh @arshinvests]

So, what do people do when their Colab notebooks are running?

[Arsh @arshinvests]

wtf Allbirds? $BIRD

Wild. All the best for AI stuff tho. Love the footwear brand. Hopefully, they do well with AI stuff too :)

New AI Era Achievement: In debt to OpenAI

[Josh Kotrous @kotro___]

We've been quiet the last few months. That was intentional.

We've been working directly with real companies, real systems, and real constraints - making sure what we're building doesn't just work in controlled environments, but is mission-critical ready.

Today, we're showing what we've been building.

Introducing Pensar Apex - an AI-powered penetration testing agent that runs directly in your terminal.

This isn't a wrapper or a chatbot. It's an autonomous agent that explores an application like a real tester, reasons about vulnerabilities, and chains multi-step attack paths. All from a single command.

We've been dogfooding Apex on our own codebase for months, and enterprise customers have been running our cloud-hosted version against their environments. The results have sharpened the product considerably - nothing teaches you what "reliable" actually means like staking your own security on it.

But the real breakthrough wasn't just building the agent - it was building a reliable validation system around it. One that forces the agent to deterministically verify its findings, continuously test its own hypotheses, and prove exploitability before reporting anything.

Because agents are easy to demo, trustworthy agents are hard to build. That shift changed everything for us. Less guessing, more proving. Less noise, more signal.

And via our cloud hosted offering, it can slot directly into your CI/CD pipeline - giving you continuous, validated pentesting results on every commit. Not periodic assessments that go stale the moment code changes. Continuous proof that your application holds up, running alongside your tests.

This is what we think the new paradigm looks like: pentesting that lives in your development workflow, not outside of it.

If you're a developer, you can run a pentest in minutes. If you're a security engineer, you can push it much further.

Try it, break it, and tell us where it falls short.

We've got a lot more coming.

I literally ran my food catering app through Apex, and it told me things that I hadn't even thought about from a security perspective (even though I spent a lot of time on ensuring the security of the app)

Thanks to Apex, our customers can feel just a little safer :)

[Kerem Proulx ⌘ @ProulxKerem]

Our autonomous pentesting agent just outperformed the two most popular open source offensive security agents on a benchmark of 60 modern, defense-enabled web apps.

Battle-tested in production against our customers' environments from startups to financial institutions, Apex consistently finds and exploits critical vulnerabilities other agents and humans miss.

Today we're releasing it open source alongside our internal benchmarks.

[Arsh @arshinvests]

@kotro___ Just doing my part :)

[Arsh @arshinvests]

Woah! This is soooo cool.

Over the last couple of days, I've had the chance to test it out, and trust me, it's an absolute game-changer if you even care a little about security!!!

@ProulxKerem Absolute banger of a release!

That kinda performance against PentestGPT and RAPTOR 🔥

I feel like Argus Benchmark might become the industry standard for security testing going forward too :)

[Arsh @arshinvests]

Midterms so crazy that I forgot to mention that I completed "System Design Interview Vol. 1"

Crazy book imo. Made me incredibly more curious about system design, but also taught a ton.

Will probably need to read it 2-3 times more to internalize topics better!

Onto DDIA :)

[Arsh @arshinvests]

Apple's dictation feature is a major time-saver, but makes a ton of mistakes :(

[Arsh @arshinvests]

Scheme can be kinda interesting...
