Here’s an experiment: purchase an anthropic pro max subscription for $200/m. Now go buy the hardware to run DeepSeek’s equivalent. In a year, who spent more?

It’s not. Do it as a hobby or for privacy but for performance just use a frontier model api. You’re paying less than cost for something that would take tens of thousands to set up locally.

Honest question. Who got to decide to accept this decision on behalf of state and federal citizens? This seems performative rather than punitive and doesn’t seem to match the harm.

My father was a plumber in the 80s and bought our family an Amiga 1000 for $1,200. Today thats about $3800 in inflation adjusted money. I just bought my son a top of the line pc for $2,000. I get that it used to be cheaper, but value is still relatively good for these machines.

When you become a parent, your risk profile changes immensely. I can hire some of the world’s best people tomorrow if i can promise them equal salary, benefits and retirement accounts for a set number of years. Plus the benefit of a large upside if it works. Most startups offer lower salaries and abysmal benefits. Security matters.

Well said. I hope some day to make it and start parent.capital a place where parents can get funding. I believe there are thousands of people out there with great ideas and immense talent who are unable to leave their salary and benefits behind to pursue them.

Thanks for all your open source work. You changed the industry for the better. Are you thinking of building a Github competitor? I would find that very appealing.

Ask HN: How do you manage your child's screen time?

pcarolan — Thu, 09 Apr 2026 00:12:07 +0000

I’m a single parent to a 13-year-old who just got an iPhone, and I’m finding Apple’s parental controls leave a lot to be desired. I'd like my kid to engage in activities outside of school, sports and screens but it's hard to motivate him when the devices are so addictive.

I’m trying to figure out: - How much screen time is actually reasonable? - What should I be okay with him accessing vs. not? - And how do you enforce your rules—tech, conversations, or something else? - What works for you when trying to encourage other activities like reading, outside time, building things, etc.

It seems simple, but I feel like I’m missing a clear approach and philosophy. Would really appreciate how others think about this.

New comment by pcarolan in "When does MCP make sense vs CLI?"

pcarolan — Mon, 02 Mar 2026 01:34:09 +0000

If you’re going this far, why even have a cli? Just have your agent grab the openapi spec from the server and set envvars. It can curl its way around happily. Security? I don’t see how this is any more or less secure than any other claude code workflow.

It seems we've round about rediscovered apis.

I tried this with datadog and it can build high quality monitoring notebooks for the pr im working on in a single shot.

New comment by pcarolan in "Feedback on an open source Ruby – LLM project"

pcarolan — Tue, 25 Nov 2025 18:04:51 +0000

As I'm on vacation, I took a couple days to put together an idea I've had bumping around in the back of my head for a while. What if you could write pure ruby methods and ask an llm to figure out all the implementation details to return the response to any method call?

The library leans hard on ruby's magical (hence the name) `method_missing` which has always impressed me with its simple cleverness.

This is my first open source project, so please leave feedback and be kind.

Many thanks in advance,

:Pat

I mostly agree, but why stop at tests? Shouldn’t it be spec driven development? Then neither the code or the language matter. Wouldn’t user stories and requirements à la bdd (see cucumber) be the right abstraction?

You can. It’s called multimodal and basically is just picking a shipping container off a train car with a crane and putting it on a truck platform or a ship. 1 platform supports all modes.

pcarolan — Thu, 24 Apr 2025 11:15:48 +0000

I’ve noticed my kid (12) primarily uses group chats over social apps. Some of his chats have several dozen kids in them. It could be social media got so bad that the protocols became the best alternative. An old programmer like me sees a glimmer of hope in a sea of noise.

pcarolan — Mon, 14 Apr 2025 02:04:05 +0000

Right. And if you use OpenAPI the agent can get the api spec context it needs from /openapi.json.

pcarolan — Wed, 26 Mar 2025 22:25:11 +0000

Yeah, I had more luck with just giving an ai the openapi spec and letting it figure everything out. I like a lot about MCP (structure, tool guidance, etc), but couldn't it just have been a REST API and a webserver?

New comment by pcarolan in "Ask HN: A friend has brain cancer: any bio hacks that worked?"

pcarolan — Fri, 10 Jan 2025 02:24:06 +0000

Lost my wife to brain cancer (gb4). After sifting through the noise, here’s what works based on stat sig research as far as I know:

1. Radiation

2. Surgery, awake craniotomy to reduce loss of function

3. Temodar chemotherapy

4. Optune helmets

5. Monoclonal antibodies

6. Maybe high dose vitamin C (suspicious results)

If I knew then what I know now I would have focused on reducing stress in our lives as it felt like it accelerated the growth, perhaps due to a weakened immune system. Quality of life and joyful moments together is the best you can hope for. It brings you into awareness of the magic of life and each other. Focus on that — which is 100% in your control.

Here is a link to the optune helmet: https://www.optunegio.com/

Ask HN: What seems obvious to game developers but not to web developers?

pcarolan — Tue, 17 Dec 2024 22:22:35 +0000

Over the years it seems the web is becoming more interactive however it feels miles away from an average game’s interactivity and real-time nature. What concepts seem totally natural and normal to game developers yet foreign and elusive to web devs?
