donpark··on Kitesurf: Agent-first browser that runs in V8 isolates
From the final notes section of their announcement blog post:

> One last thing: we're going to open source Kitesurf once we're ready — hopefully soon. Our goal is to let any customer deploy their own version of Kitesurf on their own accounts, if they want to.

donpark··on Perfection Is Not Over-Engineering
Pefection is a fetish.
donpark··on AI slop is killing online communities
Let users flag toxic users. Use the resulting toxicity score to filter out messages based on each reader’s toxicity tolerance level. Both the toxicity score and the tolerance level are driven by user flagging, with score decay over time to account for improved behavior.
donpark··on You need to rewrite your CLI for AI agents
I suspect this CLI madness is just a phase, but if the trend continues, I trust AI agents to handle the necessary rewrites.
donpark··on Show HN: I built a sub-500ms latency voice agent from scratch
But I've read somewhere that KV cache for speech-to-speech model explodes in size with each turn which could make on-device full-duplex S2S unusable except for quick chats.
donpark··on Drones that recharge directly on transmission lines
It’s just a technology that can be used for both civilian and military applications, not only by private entities.
donpark··on Make It Ephemeral: Software Should Decay and Lose Data
Decay and losses are just two of the many constraints that could be mixed like paints to create new systems.

Limitations, artificial or not, are not always bad. Walls, for example, can be seen as limitation or protection depending on how it's used.

donpark··on Writing an MP4 Muxer for Fun and Profit
Great work!

Would love to see MP4 Hybrid supported in popular packages like mp4-muxer [1] and mp4box [2] someday.

donpark··on Ask HN: Why does no one seem to care that AI gives wrong answers?
It's because AI is useful enough despite its current limitations.

Developers work with what we have on the table, not what we may have years later.

donpark··on Show HN: Semantic clusters and embeddings for 500k Hacker News comments
That's a contract between users and HN. Airtrain is a 3rd-party.

If HN API exposes personal information publicly through their API then there is a problem.

And AFAICT the only way for HN to prevent user comments from being used by 3rd-party is preventing access to those comments, meaning a) sign-up will have to be more stringent and b) visitors will have to sign-in just to read (or scrape) comments.

donpark··on Adaptive RAG – dynamic retrieval methods adjustment
KAIST is a top-tier South Korea university focused on science & engineering.
donpark··on We just launched Sketch Logo AI
Pricing doesn't look right, particularly the monthly subscription model.

What is the target market? Is there a hidden market where people need to create logos often enough to justify the subscription?

donpark··on Fine-tuning Mistral 7B on Magic the Gathering Draft
Data selection depends the use-case. Two contrasting use-cases I see are:

- Emulation

- Advisor

In case of MTG player emulation for example, I think it makes sense to group data by some rankable criteria like winrate to train rank-specific models that can mimic players of each rank.

donpark··on Asking ChatGPT to Repeat Words 'Forever' Is Now a Terms of Service Violation
Leaking original data would expose the company to direct copyright violation lawsuits. Changing T&S is simplest way to stave the legal risk exposure, buying time to implement technical remedies.

As ridiculous as it may seem, they're doing the right thing.

donpark··on MeshGPT: Generating triangle meshes with decoder-only transformers
How does this differ from similar techniques previously applied to DNA and RNA sequences?
donpark··on Ask HN: Is anyone else bearish on OpenAI?
I think OpenAI's founding nature is about research so it will disappear when it either runs out of key problems to solve or funds, whichever comes first. I see its commercial efforts as driven primarily to maximize their research runway. Operating ChatGPT commercially also helps research into ML-related UX and operational related problems.

That said, I cannot rule out purely commercial ventures with tenacity necessary to compete spinning out of OpenAI.

donpark··on The Humane AI Pin Launches Its Campaign to Replace Phones
Think about aging population. As to privacy, same problem exists with taking phone calls in public yet we somehow manage just fine.
donpark··on Kalman filter from the ground up
Another good article on the subject:

Is the Kalman filter a low-pass filter? Sometimes!

https://jbconsulting.substack.com/p/is-the-kalman-filter-jus...

PS: I've used it to remove jitter in virtual camera movement while cropping video around faces in real-time, streaming detected face locations to a Kalman filter worker and get back stream of stable camera locations.

donpark··on How to see bright, vivid images in your mind’s eye (2016)
It 'feels like' like seeing. There is sense of dimension and position in the space and objects. I can imagine people I know and places I've been to with amazing details but visual details like texture are limited to where I'm focusing. Rest of the view is filled with 'feels like they are there'. It's not retrieval because when I try to focus on non-memorable parts of a face, I can tell that details are made up on-demand using common variety.

And what I 'see' is affected by light over closed eyelid as well as inner blood vessel, minor debris and micro organism floating over the cornea, meaning input from the eyes does play a role even with eyes closed.

While I have very vivid imaginations, I don't think I have photographic memory because what I can recall is rather too creative.

donpark··on Svelte 5: Runes
Unless I misunderstood, Svelte 5 'runes' appears to be just 'markers' making explicit what used to be implicit with two noteworthy benefits:

- simpler compiler implementation - easier to identify moving parts

If so then the intro article needs a rewrite to be simpler without unnecessary districting details.

donpark··on GPT-4 is not getting worse
Very likely. Typical serverless hosts like Vercel times out at 5 minutes.

donpark··on When did Postgres become cool?
With me, it was around 5 years ago although first inkling started w/JSON support 8 yrs ago.
donpark··on Remote work requires communicating more, but less frequently
Pair junior developer with a senior, starting with an hour every other day.

I had more problems with junior developers who think they're senior developers (some experience, high-confidence) bc they don't ask for help when they should.

donpark··on IRC is the only viable chat protocol (2022)
Importance of a feature depends largely on use-cases.

Chat is not just for business. Its use-case existed even before notion of business came to be.

donpark··on Langchain Is Pointless
I agree that LangChain is pointless for experienced ML developers building products. For the rest, I disagree as just getting to the point where same observation can be made is worthwhile.
donpark··on W3C and My RSS Spec
Excellent.
donpark··on W3C and My RSS Spec
He is now asking. Are you saying it's too late?
donpark··on W3C and My RSS Spec
Respect is also a useful tool. It reduces conflicts just as diplomacy reduces violence. Yes, respect can be set aside but, when you do, expect controversy.

Why would anyone want to invite unnecessary controversy when writing a spec?
