12 karma · joined August 15, 2012

I'm an engineer and engineering leader who still writes code. I spent nearly nine years building a cloud and platform org from scratch, and I now work on security as a distinguished engineer.

I write about platform engineering and agentic software development at https://vinny.dev

On the side I ship iOS and Mac apps (GSD Task Manager, TravelTimes, PourCraft Coffee) and open source tools like Tycho and AgentMachinist. Code: https://github.com/vscarpenter

Linux user since SLS and Slackware.

vscarpenter··on Launch HN: Agent37 (YC F26) – Low-cost agent sandboxes for running agents
How do you see this fitting with AWS’s Strands Box from last week? Box isn’t hosted compute. It’s an open-source sandbox plus a policy engine that checks shell, Python, egress, and MCP calls, and swaps credential placeholders for real secrets at the gateway. That’s the broker layer ekorondy and talkarimli are asking about.

Two questions: Could a policy layer like Box run inside your gVisor sandboxes, or would it need your full-VM tier? And on price, have you compared against AgentCore Runtime? It bills CPU only while active, which targets the same bursty pattern you’re optimizing for.

vscarpenter··on Apple HomeView
I think the Watch is a better precedent than the Apple TV. The product page already borrows its vocabulary: customizable faces, Live Activities, and “compatible third-party audio and video apps from your iPhone.” That’s how WatchKit started in 2015. Third-party Watch apps ran as extensions on the paired iPhone, went native with watchOS 2 later that year, and didn’t get an on-device App Store until watchOS 6 in 2019.

So I wouldn’t expect a HomeView App Store soon. I’d expect iPhone-hosted extensions first (widgets, Live Activities, CarPlay-style templates for audio and video), probably at WWDC. That also spares developers who are already scrambling to support the Duo.

vscarpenter··on Web Search API
I guess I'm not understanding the value here - to compete with Google and the likes, the scale, cost and complexity would be huge. Appreciate new entrants in an existing field but not seeing this one.
vscarpenter··on Why I Actively Discourage Online Tooling like jwt.io and Online JSON Validators
Agree 100%. At my company, I've deployed the open source version of JSONLint.com internally to prevent any accidental exposure of internal or confidential data.
vscarpenter··on Introducing Money in Excel, an easier way to manage your finances
Exactly - this is a silly choice. Making it inaccessible to users of Office 365 for business is a terrible default choice.
vscarpenter··on Ask HN: Anxiety is limiting my enjoyment of a wonderful career. Can you relate?
I have friends and family members that suffer anxiety ranging from minor to debilitating anxiety where they feel like they cannot function. As davidkim suggests below, meditation, sleep and even exercise can help alleviate some of the symptoms but you also have to know that anxiety/OCD can be caused by a chemical imbalance in the brain and you simply cannot wish it away. Medicine may be appropriate in your situation and so I would start with a consultation with your doctor. No one should suffer and miss out on the wonders of life.
vscarpenter··on Stamplay: IFTTT for developers
Is there a JSON parsing component that I'm missing? I would think a simple JSON component would allow you to hook up any number of API's together to build an application. Assuming it's on your roadmap.

Yes - check out https://www.fsisac.com/
vscarpenter··on Ask HN: Do you use Web Application Firewall (WAF)?
I use mod_security for personal sites and Cisco NetScaler as a WAF, load-balancer and SSL offloader at work. If I was given the choice, I would use HAProxy and mod_security as I'm not too impressed with NetScaler.
vscarpenter··on Square open sources Kochiku
I'm curious as to why Square would spend engineering talent on a distributed CI system when you can buy something like Jetbrains TeamCity that does what they wanted to do. This is not meant as a slam and I am also a developer who loves to build things but I would think Square and other companies for that matter would want to apply their limited engineering talents in solving bigger problems that grow the business.

Not looking for a flame war - just curious to get different perspectives.

vscarpenter··on Show HN: I wrote an eBook on building iOS apps. First chapter is free.
Great job Ash. Congratulations. I got to see a little bit of the book development happen via GitHub and it was great to see how crowd-sourcing technical review/editor function could potentially work in the future.

Congratulations again.

vscarpenter··on Snag.gy - Paste images directly to the web
Is there a freeware or commercial WYSIWYG editor that supports pasting of images like this awesome tool?

I have a use-case where users are creating charts in Excel and want to paste them into a HTML textarea and WYSIWYG editor that supported paste of images from the clipboard would be awesome. Thanks
