Show HN: Config-driven extensions to ghuntley's ralph loop technique

I recently came across Chris Parsons' "Your Agent Orchestrator is Too Clever" which talks about Ralph loops, initially proposed by Geoffrey Huntley. while :; do cat PROMPT.md | claude-code ; done Tried it on a real project. Realized that single line, even though concise, doesn't handle real-world complexity - multiple repos, git history, build failures. So I built some tooling around...

Re:Any insider takes on Yann LeCun's push against current architectures? on Friday March 14, 2025 @07:05PM (#43368251)
Doesn't Language itself encode multimodal experiences? Let's take this case write when we write text, we have the skill and opportunity to encode the visual, tactile, and other sensory experiences into words. and the fact is llm's trained on massive text corpora are indirectly learning from human multimodal experiences translated into language. This might be less direct than firsthand sensory experience, but potentially more efficient by leveraging human-curated information. Text can describe simulations of physical environments. Models might learn physical dynamics through textual descriptions of physics, video game logs, scientific papers, etc. A sufficiently comprehensive text corpus might contain enough information to develop reasonable physical intuition without direct sensory experience.

As I'm typing this there is one reality that I'm understanding, the quality and completeness of the data fundamentally determines how well an AI system will work. and with just text this is hard to achieve and a multi modal experience is a must.

thank you for explaining in very simple terms where I could understand

I will probably recommend csprimer, this is hands down one of the best introductions that I found and I recommended to a lot of people who reached out to me. The order I will probably recommend is the following

1. Programming: Beyond the basics

2. Computer Systems

3. Operating Systems

4. Algorithms and Data Structures

5. Computer Networks

This is going to take time but it will be worth your time.

For discrete Math I sincerely recommend you to take a look at this book "Discrete Mathematics with Applications by Susanna Epp. This is an excellent book and it has good problems.

I will also recommend you to look at https://fa24.datastructur.es/ this is a very good beginner course on data structures that is completely free by UC Berkeley

Re:Ask HN: Resources to learn about early startups engineering decision? on Monday May 22, 2023 @06:29PM (#36037491)
The 2 metrics I've used in the past is

1. Bounce rate combined with Session length

- Bounce rate can be defined as % of users who leave only after viewing one or few pages. The reason at least I coupled bounce rate with session length is atleast in the app we work there are few personas that prefer to stay in one page for a long period of time and do some interactions. Bounce rate combined with Session length always give us a good picture are folks using the feature(s) as intended. One thing we did was set a baseline metric where we first measured session length on the app as well as per page basis, and after that we could build the bounce rate. Amplitude works well for this case

2. Churn Rate - number of users who stop using the app over a given period. This should be easy to do by querying db if you maintain some session duration information.

Re:Ask HN: Resources to learn about early startups engineering decision? on Friday May 19, 2023 @09:37PM (#36008639)
I'm an engineer and talking from experience here.

1. keep the db schema simple. remember you are startup things change, so does the db schema so does your architecture.

2. One piece of advice from personal experience, Microservices usually don't work well for startups try building your solution as a modularized monolith.

3. always make decisions that are reversible (2 way door) and make sure coming back is also easy.

4. for any features you release have qualitative and quantitative metrics and more importantly guard rail metrics.

5. where ever you can use the an off the shelf solution like feature flags (launchdarkly), product analytics (amplitude) use them. These are solutions used by countless startups do not reinvent the wheel.

6. prioritize customer feedback, that is going to get you money and they are going to help make your product better. Instead of "failing fast" prioritize on "learning fast".

7. Be focussed on solving the problem don't romanticize the solution.

Re:Learn Go in five minutes on Tuesday January 05, 2021 @02:16PM (#25649698)
Absolutely no offense to the author, but IMO for an experienced programmer the five minute intro does not make any sense. They will be better served by using the documentation (or) go by example in this case.

If someone is new to programming this in no way does any justice. Programming is way too complex to be fit in 5 minutes intro. https://norvig.com/21-days.html

Re:Learn Go in five minutes on Tuesday January 05, 2021 @02:12PM (#25649624)
One resource that atleast comes close to what you are talking about is the information at go101.org, not sure if you have seen this before. Especially the section on Go Type System and Concurrent Programming is really very good and they focus on how to leverage the feature correctly for the most part. Hopefully you like it https://go101.org/article/101.html
