You can read more from me at my site: http://www.joshualyman.com

A technologist, founder, and current Googler, I've repeatedly taken products from inception to commercial success across sectors, from startups to Fortune 10 companies. My specialty lies in bridging the gap between business vision and technical execution, deeply engaging with code and who mentors teams. Beyond engineering, I bring a global perspective from living abroad for nine years and speaking fluent French.

I chuckle knowing that somewhere in Apple there is an SRE or engineer who is getting paged for elevated 404 rates, and has to silence the pages hoping that no real missing page issue crops up while we all hit this page. :)

To me, the common theme here in all of these hacks has been the company Irregular, which it looks like all the labs are using for sandboxing. But it looks like the sandbox may be a bit… lacking?

Yes, the models are smart when they find a way out, but their instructions are, in a way, deliberately open such as to be a case for misalignment in these cases anyway. It’s a capture-the-flag assignment in the Gemini case, and in the OpenAI cases they were broad instructions to best the reward function. As part of alignment studies, this is literally what you’re trying to observe and then work with. If Irregular’s sandbox had been a little more boxy, there wouldn’t be these issues.

I’m not saying we have zero problems here on the AI side, but I’d certainly be reviewing my contract with Irregular at this time if I were playing in the space. It would be just as interesting to learn more about their sandboxing techniques as it would the models in these particular scenarios.

Axo | Lead Founding Engineer | Sugar Land / Houston, TX (HYBRID) | Full-time | $120k–$160k + Founding Equity

Want to help out healthcare providers? Clinicians using our software are already saving hours a day and loving their job again. We are building Axo to make the software layer as invisible and ambient as possible, letting clinicians direct 100% of their attention to patients rather than screens.

Our first market is orthotics and prosthetics (O&P), the field designing braces and artificial limbs that restore human mobility and underserved by the tech sector. You’ll join as a founding engineer working directly with myself (former Google SWE) and my co-founder (one of the US's best known O&P clinicians), and small engineering team we want to grow.

You will own massive surfaces end-to-end, making foundational architectural decisions for our entire platform. We've got a massive pipeline ahead and need your help to build it. And we participate in humanitarian missions to expand prosthetic access in critical parts of the world like Ukraine and Sri Lanka.

- The Stack: C#/.NET, gRPC, SolidJS/TypeScript, and PostgreSQL, built with strict domain-driven design and rigorous testing.

- How we work: Flexibility! Love AI-assisted speed coding? Go for it. Prefer to write by hand because your mental model is faster than prompting? Perfect. We only care about delivering safely and quickly.

- Requirements: Senior-level depth with production systems, a strong habit of domain modeling, and a philosophy that defaults to simplicity. Strong UI/UX experience with an obsession for user simplicity is a must.

To apply, email me directly at [email protected] with a short story about a favorite technical challenge you solved end-to-end. Please put "HN" in the subject line! MUST be in Texas.

Upvoting if for nothing else than the intro paragraph to the repo. That was hilarious and so true.

Axo Ventures | Senior Software Engineer (Founding Team) | ONSITE: Houston, TX (Sugar Land) | Full-time | $100k–$140k + Founding Equity, adjustable

Clinical software is where a provider's time goes to die. We are building Axo to make the software layer as invisible and ambient as possible, letting clinicians direct 100% of their attention to patients rather than screens.

Our first market is orthotics and prosthetics (O&P), the field designing braces and artificial limbs that restore human mobility and underserved by the tech sector. We're building a foundation designed to eventually scale across thousands of providers and multiple medical specialties.

You’ll join as a founding engineer working directly with myself (Xoogler SWE) and my co-founder (one of the US's best known O&P clinicians), and a new engineer. You will own massive surfaces end-to-end, making the foundational architectural decisions for our entire platform. We have clinics using our suite and already saving hours a day, but we've got a massive pipeline ahead and need your help to build it. And we participate in humanitarian missions to expand prosthetic access in critical parts of the world like Ukraine.

- The Stack: C#/.NET, contract-first gRPC, SolidJS/TypeScript, and PostgreSQL, built with strict domain-driven design and rigorous testing.

- How we work: We have total flexibility on your workflow. Love AI-assisted speed coding? Go for it. Prefer to write by hand because your mental model is faster than prompting? Perfect. We only care about delivering safely and quickly.

- Requirements: Senior-level depth with production systems, a strong habit of domain modeling, and a philosophy that defaults to simplicity. Strong UI/UX experience with an obsession for user simplicity is a must.

> tl;dr: AI writes features, not architecture.

This. I definitely agree with this statement at this point in AI-assisted development. This gets at the "taste" factor that is still intrinsically human, especially in software engineering. If you can construct and guide the overall architecture of an application or system, AI can conceivably fill in the smaller feature bits, and do so well. But it must have a strong architecture and opinionated field in which to play.

I've had at least 256GB on my phones for the last couple of generations after having had to deal with storage issues beforehand, and it's been much nicer.

But I picked up a 16e for my son a few months ago, with 128GB, and yes, we're running into issues with storage space when it comes time to do an OS update. Between local music and photos storage, base storage, and the image for the new update, two or three times now we've had to delete stuff temporarily in order to get the update going. So I'm happy the new base is 256GB, at least that will probably last us a couple more generations before ~~640KB~~ 256GB is enough for everyone.
