caprock··on Retrieval is not the future of AI – if it was, Google would have won already
Few things are all or nothing in life. There are many forms of retrieval and many conditions for their use. In some scenarios it is helpful to have retrieval with LLMs and other times less so.
caprock··on Ask HN: Procrastination with AI?
It's interesting how one AI approach is to do similar amounts of work with less intensity and energy. Glad it has improved your mental health.
caprock··on Ask HN: Procrastination with AI?
Sounds pretty cool!
caprock··on Ask HN: What was the biggest contributor to your happiness in the past year?
Having a strong internal locus of control, balanced with prayer centered around gratitude.
caprock··on Ask HN: Are people generally interested using LLMs for learning purposes?
Same. The ability to investigate a topic from almost any angle or starting point has been really fun and helpful.
caprock··on Ask HN: What are you working on? (June 2026)
Agreed that it's an underserved market (personal genome sequencing).

Do you own or have access to a sequencing platform / machine? Or do you just buy and prepare kits, and then send the prepared sample out for sequencing?

caprock··on Pro Max 5x quota exhausted in 1.5 hours despite moderate usage
Roughly agreed. I'm a bit baffled when it seems like someone is having long conversations with multiple tasks and loads of add-ons. I generally have one or two iterations and then a new session.

I'm using another tool, not claude code, but I don't think that matters much.

caprock··on The Last Quiet Thing
In many many ways our technology is not working on our behalf. Even though it seems possible.
caprock··on Ask HN: Any Interesting Niche Hobbies?
You might look into applying RL in the domain of low cost robotics and drones. That would draw on some of your past experience but applied to a domain (robotics) which I perceive is seeing renewed interest.
caprock··on The risk of AI isn't making us lazy, but making "lazy" look productive
I find value in learning some things deeply but not all things.

The ability to be more selective about where I attend deeply, while leveraging fast shallow learning to complete other tasks... That seems like a potential benefit and a nice choice to have in the toolbox.

caprock··on Ask HN: How do you get recommendations for books that are up your alley?
It's technically quite feasible with modern search and language model technology.

The challenge is in acquiring all the book text, meaningful cost to implement, and minimal paths to revenue generation.

For various reasons, the organizations that have the text aren't incentivized to deliver best recs for a user, as tim noted.

caprock··on Ask HN: What's the best advice your would tell your 20 year old self?
Basic index etfs for Nasdaq and SP500.
caprock··on Ask HN: How do you get recommendations for books that are up your alley?
It's intriguing how book recs aren't really that good anywhere. I mean they are ok, but rarely great. Google and Amazon have most of the text but still don't solve this so well.

In any event, I sometimes use GoodReads. You can go to the page for a representative book and then start browsing the "readers also enjoyed" list.

I also use LibraryThing in a similar way.

caprock··on Ask HN: What's the Deal with Forward Deployed Engineers?
Significant chunks of the software engineer community self select into minimizing time spent with customers or even any non-engineers. It's understandable but unfortunate too.

I would suggest looking for people that were initially hands on but converted to sales engineer or professional services roles. Some switch because they don't like the programming. Some will quietly be very good engineers that have seen a lot of scenarios.

You'll have to pay a premium for travel if you want to get experienced people that have families at home.

caprock··on Ask HN: What's the best advice your would tell your 20 year old self?
- Invest money from each paycheck.

- Make a practice of walking daily.

- Casually lift a few times a week.

- Pray daily. Focus on gratitude.

caprock··on Ask HN: Realistic prospects of getting back to management later
Yes, very realistic.

Search for the engineering / manager pendulum online to see various discussions on the topic.

There are lots of differences between management in a startup vs a larger or more mature company too.

caprock··on Ask HN: How to stop an AWS bot sending 2B requests/month?
Agreed. You should be able to set the waf to just drop the packets and not even bother with the overhead of a response. I think cloud flare waf calls this "block".
caprock··on Ask HN: What are you working on? (September 2025)
Where do you get the data?
caprock··on Ask HN: What is one thing that help you the most to become a better engineer?
Working in ISP and Managed Hosting environments made me a better engineer. Lots of unix/linux, networking, DNS, etc. Lots of support and problem solving. It all led to both a breadth and depth of experience. It's been a useful foundation for my career even after moving into other areas like swe and ml.
caprock··on The DHS has been harvesting DNA from Americans for years
The X-Files was right all along
caprock··on Ask HN: In hindsight, what would you change about you education?
Several ideas off the cuff:

* More work semesters like Waterloo

* A class on career planning

* A class on financial planning

* Philosophy of science and engineering course

caprock··on Leaving Google
I've found a lot of value in the habits of politeness, especially in written communication. It's disappointing when it's not a first class citizen in a company culture for things like code review. There are plenty of rationalizations for how it might not be needed, but that just feels like laziness.
caprock··on Itter.sh – Micro-Blogging via Terminal
Agreed! I have enjoyed how the constraints will prod me to refine and distill an initial thought into more crisp phrasing.
caprock··on Ask HN: Do CS grads become more open-minded as they age?
Possibly, but I doubt age is a primary cause. Openness to experience is a well identified personality trait which is unevenly distributed. Check out the "big five" concept from psychology for more info.
caprock··on Ask HN: What are you working on? (April 2025)
Dns gateway to redis is a fun idea
caprock··on Ask HN: Can't publish on the Play Store without a physical office?
You can pay a small fee to have a "registered agent" service and that can include an address you can use.
caprock··on We're running 50 LLMs on 2 GPUs – no cold starts, no overprovisioning
Are you going to open source this? Is anyone else (ex: Modal) doing this?
caprock··on What is vibe coding, exactly?
You're better off avoiding all the second hand articles around definitions and value, and do two things:

1. Try and explore using AI for various parts of the programming processes.

2. Find interesting engineers that write about the same explorations and observe.

caprock··on Ask HN: Best books you've read on becoming a manager (of Sales and Eng Roles)
Managing Humans by Michael Loop

Many of the chapters are derived from his blog posts if you want to get a feel for it.

caprock··on Ask HN: How to transition into Robotics
Find example companies, find their current or past jobs postings (maybe use the wayback machine), and identify the specific technology and techniques they request. Use that to write a map and plan.

Start using those technologies and building things. Write or at least post about it on X and follow related engineers on X. See kache's robotics journeyman community as one place for inspiration.
