jjfoooo4··on Tesla kills Autopilot, locks lane-keeping behind $99/month fee
Isn’t lane keeping pretty standard for most new cars?

It’s like an upside down freemium model - try out our basic self driving product, which is (now) the worst in the market, so you’ll convert to the premium FSD offering.

jjfoooo4··on Capital One to acquire Brex for $5.15B
I think the investors who put $300m in at a $12b valuation would disagree
jjfoooo4··on MCP is a fad
Should be fixed now (albeit by hastily removing dark mode)

This would be my critique of MCP-specific security implementations. I think robust tools for this already exist, and in general AI API calls can and should be treated like any other RPC call.

Looking at the post again, I think I agree that calling Claude Skills overengineered is too harsh. I think Skills is definitely an improvement over MCP.

However I still think it's a generally a mistake to put useful commands and documentation in AI-specific files. In my opinion a better approach is to optimize the organization of docs and commands for human usability, and teach the AI how to leverage those.

I do use Claude Skills, but only to wire up just commands. I wrote a little package to do this automatically: https://github.com/tombedor/just-claude

Thanks for flagging! I just pushed an update that should fix this

jjfoooo4··on Donating the Model Context Protocol and establishing the Agentic AI Foundation
There’s nothing special about llm tools. They’re really just script invocations. A command runner like just does everything you need, and makes the tools available to humans.

I wrote a bit on the topic here: https://tombedor.dev/make-it-easy-for-humans/

jjfoooo4··on Apple's slow AI pace becomes a strength as market grows weary of spending
The existential hope that all the other players have is that AI will drive adoption of a form factor that replaces the phone. Because if in 5 years the dominant device is still the phone, Apple wins.

Consumer hardware chips will be plenty powerful to run “good enough” models.

If I’m an application dev, do I want to develop something on top of OpenAI, or Apple’s on device model that I can use as much as a I want for free? On device is the future

jjfoooo4··on Donating the Model Context Protocol and establishing the Agentic AI Foundation
It really feels to me that MCP is a fad. Tool calling seems like the overwhelming use case, but a dedicated protocol that goes through arbitrary runtimes is massive overkill
jjfoooo4··on Netflix to Acquire Warner Bros
That video game/superhero IP adaptations are considered "prestige TV" says more about diminished creative expectations than HBO continuing to uphold it's traditional high standards.

Nothing against people who like them, to each his own. But the throughput of quality programming out of HBO has dropped off a cliff through it's multiple changes in ownership.

jjfoooo4··on Apple Releases Open Weights Video Model
My guess is that they will lean towards smaller models, and try to provide the best experience for running inference on device
jjfoooo4··on Pebble, Rebble, and a path forward
That’s the risk you run when you contribute work to open source.

Unless there’s an accusation that Eric / Core is violating license, I don’t see a lot of merit to Rebble’s position.

jjfoooo4··on Waymo Was on a Roll in San Francisco. Then One of Its Cars Killed a Cat
>>> They pose a major threat to birds, killing an estimated 2.4 billion birds each year in the U.S. alone, making cats the top source of direct, human-caused bird mortality in the U.S.

Is this the stat you have issue with? Or is the contention that a pet on a city street at 11:40 PM is not highly at risk of being run over by a human driver?

Other very relevant, undisputed context: the accident happened at 11:40 at night
jjfoooo4··on Waymo robotaxis are now giving rides on freeways in LA, SF and Phoenix
I mean, isn't the most common reason people tailgate is that they're frustrated that a slow driver is in a lane they want to use to drive fast in?
jjfoooo4··on Waymo robotaxis are now giving rides on freeways in LA, SF and Phoenix
Yes. People do in fact safely drive the speed limit.

If "we'll have too many cars on the freeway following the speed limit" ranks as a serious concern, I think we've really lost the plot.

I recently drove by a fatal accident that had just happened on the freeway. A man on the street had been ripped in half, and his body was lying on the road. I can't imagine the scene is all that unlike the 40 thousand other US road deaths that happen every year.

As a driver I'm willing to accept some minor inconvenience to improve the situation. As a rider I trust Waymo's more than human drivers.

Waymo is in another league compared to every other autpilot system out there - I've used Tesla, Toyota, and Cruise before it got shut down.

The political climate is VERY suspicious of autonomous vehicles, but they most serious incident I can really recall was the recent one where a car ran over a cat. You can see the reaction here: https://www.reddit.com/r/cats/comments/1omortk/the_shrine_to...

If the biggest black mark against the company is running over a cat on the street at 11:40 PM (according to Waymo, after it darted under the car), I feel pretty good.

jjfoooo4··on Ask HN: What Are You Working On? (Nov 2025)
I’m working on an AI-assisted reminders app using on device models for iOS.

Things like, “get xyz a birthday gift”, and it finds the contact and sets the reminder for a few weeks before the birthday.

The source data is calendar and contact info, but the nice thing about local models is that no data gets sent to providers, and the app can be cheap

jjfoooo4··on The Case Against PGVector
When using vectors / embeddings models, I think there's a lot of low hanging fruit to be had with non-massive datasets - your support documentation, your product info, a lot of search use cases. For these, the interface I really want is more like a file system than a database - I want to be able to just write and update documents like a file system and have the indexes update automatically and invisibly.

So basically, I'd love to have my storage provider give me a vector search API, which I guess is what Amazon S3 vectors is supposed to be (https://aws.amazon.com/s3/features/vectors/)?

Curious to hear what experience people have had with this.

jjfoooo4··on EVs are depreciating faster than gas-powered cars
For a two car house, having one electric and one ICE vehicle seems like a no brainer, assuming charging space at home
jjfoooo4··on Claude Skills
I see this as a lower overhead replacement for MCP. Rather than managing a bunch of MCP's, use the directory structure to your advantage, leverage the OS's capability to execute
jjfoooo4··on New York Times, AP, Newsmax and others say they won't sign new Pentagon rules
> most draconian new rule

aka the entire point of the exercise. The innocuous components are there so that the Dept of Defense can claim that it's those minor items the press is objecting to, without having to defend the actual substantive policy change.

jjfoooo4··on Liquid Glass Is Cracked, and Usability Suffers in iOS 26
Just because it took me a second to figure out: swiping left or right works when done on the search bar, not anywhere on the screen
jjfoooo4··on A comparison of Ada and Rust, using solutions to the Advent of Code
Can you say more about what you mean by wait faster? Is it as in, enqueue many things faster?
jjfoooo4··on Meta will listen into AI conversations to personalize ads
I'm very curious to know what kind of adoption Meta's AI features are getting. The idea of anyone wanting to talk to AI persona's in a similar way to how they talk to their friends is completely bizarre to me, but they seem to be pushing it quite hard
jjfoooo4··on Meta Ray-Ban Display
It was painful even before it started malfunctioning

I play pickup basketball and young people play with them in. I wouldn't do that, but they are pretty secure if properly fitted
jjfoooo4··on ABC yanks Jimmy Kimmel’s show ‘indefinitely’ after threat from FCC chair
The Sinclair statement is just bizarre. Kimmel is to pay restitution to Kirk's (millionaire) widow because of statements he made about the political reaction to his death?

The pretext is really falling away.

jjfoooo4··on ABC yanks Jimmy Kimmel’s show ‘indefinitely’ after threat from FCC chair
I expected Kimmel to have somehow criticized Kirk, a dubious enough reason to pull the show. But this isn’t even that. Comments quoted in stories assert that the shooter was MAGA - maybe that’s somewhat controversial, but it’s ludicrous to suggest it’s offensive. That paired with comments criticizing the Dear Leader were enough. This is a new low in corporate cowardice toward Trump bullying.

Terrible precedent aside, how could Disney think that capitulating here will result in anything other than more attempts to control their programming in the short term?

Kimmel in no way endorsed the shooting
