Suggestion:

Everyone think of a number between 0~9, put it in a bracket (so that it's search-friendly), and add it to their post, e.g. "[7] check out my example.com".

Readers of this thread are then encouraged to search for a random number between 0~9, search for it (e.g., "[5]") via browser, do a few "find next" (just to randomize), and then visit as many results as they enjoy.

Ask HN: If other people can't edit, is a "personal wiki" a wiki?

tslmy — Mon, 19 Aug 2024 03:06:56 +0000

By definition, "a wiki is a form of hypertext publication on the internet which is collaboratively edited and managed by its audience directly through a web browser."

(https://en.wikipedia.org/wiki/Wiki)

Emphasis on "collaboratively edited" -- If only one person can edit the content, it by definition isn't a wiki, is it?

There are many "personal wikis" on the internet, each of which only editable to its owner only. I feel that it is an abuse of the term. If you agree with me, what do you think would be a better name for those kind of systems?

I myself is leaning towards "digital garden", but I would like to hear about your ideas.

New comment by tslmy in "Ask HN: Is RAG the Future of LLMs?"

tslmy — Sun, 14 Apr 2024 22:51:39 +0000

To make a LLM relevant to you, your intuition might be to fine-tune it with your data, but:

1. Training a LLM is expensive.

2. Due to the cost to train, it’s hard to update a LLM with latest information.

3. Observability is lacking. When you ask a LLM a question, it’s not obvious how the LLM arrived at its answer.

There’s a different approach: Retrieval-Augmented Generation (RAG). Instead of asking LLM to generate an answer immediately, frameworks like LlamaIndex:

1. retrieves information from your data sources first,

2. adds it to your question as context, and

3. asks the LLM to answer based on the enriched prompt.

RAG overcomes all three weaknesses of the fine-tuning approach:

1. There’s no training involved, so it’s cheap.

2. Data is fetched only when you ask for them, so it’s always up to date.

3. The framework can show you the retrieved documents, so it’s more trustworthy.

Here's an alternative:

Spend seed round investments on building a solid software but not building an income stream that can satisfy investors, thus not receiving any new funding and let the company die.

Hmmm... OpenAI itself?

Did you intend to rule out OpenAI from consideration?

You mentioned hardware being a constraint, but that doesn't tell me why you specifically wanted to find an alternative to OpenAI.

Would you be able to spare some time and find us some references here? Despite a native Chinese speaker, I can't seem to gather up the correct terms on baidu.com google.com to get me relevant materials on that pre-Android-era mobile OSes.

Oh yes, thanks for bringing up the pre-Android-era Shanzhai phones. Were they on WinCE? I was too young to get my hands on one for any first-hand experience.

They were... creative!

Mainland-born Chinese here.

Xiaomi basically killed Shanzhai smartphones (the sector of all Shanzhai techs chosen by the OP) by releasing Xiaomi (and later Redmi) smartphones.

Xiaomi made Android smartphones affordable. How affordable? Here's a clip of the debut event of Xiaomi's first smartphone back in 2011:

https://www.bilibili.com/video/BV1Xx411v7XX/

Scrub to 01:54. That's a table of the flagship smartphones at that time. The last column of the table is the price in CNY. 3k, 4k, 5k -- around that range.

Now scrub to 03:20 where their CEO announced the MSRP. Listen to that 30-second-long "wow". Look at that price. The astonishment was real.

That's the price range of Shanzhai smartphones.

On a flagship-spec'd smartphone.

That's monumental in the history of smartphone evolution in China. Ask any friend of yours born & raised in mainland China. I bet none would argue otherwise.
