Honestly - the video barely touches on this at all, despite making it the "hook".

I was pretty disappointed that he doesn't discuss the EMAS mechanics, structure, actual stopping distance, or impact to the plane in nearly any real way.

He does show a LOT of animation of layered runways, which are mostly not that informative.

There is some decent discussion around maintenance and material choice, and some very basic discussion of infrastructure requirements outside of the runways themselves that's... ok.

Overall... I thought this was a solid C+ video. It shows planes plowing into an EMAS, then does jack all to discuss that, while bringing up a lot of less interesting discussion of runway building (which despite the claims in the video, do actually correspond very highly to how we build highways, just with different weight/maintenance requirements.)

Yeah, they've just closed the one near me. I think they underestimated how hard it would be, at least in the UK - the existing supermarket chains are already competitive, mostly pretty good, and people have surprisingly high brand loyalty to them. I don't think I've even talked to anyone who has shopped in Amazon Fresh, or even wanted to.

Sorry if I was the one to bring hostility into this or project. On the other hand, I also feel like what I wanted to talk about and brought up was dismissed and responded to with strong labels which are hostile in nature and shut down open conversation and open thought. I've had enough of and seen this type of personality and attitude enough in my life to just instantly trigger defensiveness to protect myself. I feel I received that from you and it mirrors what I've received my journeys breaking through religion and cult. When I see the pattern I like to call it for what it is.

I think investors like Amazon taking shots like this? It was never a broad roll-out, 43 stores is micro-scale for Amazon.

Still, would love to see a breakdown of why it didn't improve. Regardless of the accuracy at launch, I'd think that advances in AI would have been massively to their advantage. I wonder if security degradation hit them hard.

The entire system depends on a level of social trust that doesn't exist in American cities today. Similarly, the "Dash Cart" seems like a cheaper and easier way to accomplish the same thing.

At the end of the day, there's also a mismatch in the use case. If I'm going to a smaller format store, like they had, I'm not buying a ton of stuff. Self checkout is great, and minimal friction.

I'd think that improving the UX of self-checkout gets 80% of the way there with way less fraud, way less theft, and way less technology.

Still, I think it's wicked cool they took a big shot.

I know someone that worked on the project in the early days. It was always incredibly difficult technology, they were always behind on their accuracy targets, and the solutions were increasingly kludgy as they layered more and more complex systems on top. An honorable failure.

A lot of smart people really tried to make it work.

Yes, I do interpret your “draw development away from X” as suggesting an attempt to damage X (sorry if I misinterpreted your post, but I do think my interpretation was not really that unreasonable).

This “blessed successor” without and detrimental effects as a main goal: that’s pretty close to my understanding of the project. IIRC some X people were involved from the beginning, right?

Almost every major US criminal constitutional rights case started with an actual criminal, or at least someone unsavory. Miranda was a rapist. Gideon of Gideon v. Wainwright was a burglar. Brady of Brady v. Maryland was a robber and possibly a murderer. These cases helped form the foundation of what due process actually means in the United States. But contemporary discussion surely included a lot of commentary like "Why would anyone be opposed to prosecuting murders, rapists, and violent criminals?" And that commentary was just as irrelevant then as it is now.

It's not about whether the US deports criminals. It's about how we go about doing it.

Given enough time of human survival, the only species left on this planet will be ones that are aesthetically pleasing to us

Everything selectively bred due to environmental or artificial pressures to have big eyes, big heads, high vocal sounds, attributes of human babies

It is very strange and an aberration amongst species, one being tolerating other beings because of their entertainment value and the joy they give from looking at them, but seems to be consistent and validate what's happened over eons of homo sapien propagation

This is an antidotal example, but I released this last week after 3 months of work on it as a "nights and weekdends" project: https://apps.apple.com/us/app/skyscraper-for-bluesky/id67541...

I've been working in the mobile space since 2009, though primarily as a designer and then product manager. I work in kinda a hybrid engineering/PM job now, and have never been a particularly strong programmer. I definitely wouldn't have thought I could make something with that polish, let alone in 3 months.

That code base is ~98% Claude code.

My bet is that too many frogs are gonna leap, that this is far too shitty a situation right now. They are gonna work extra overtime to cool it down some for now, collect & put some frogs back in the pot. And then slowly turn up the heat again.

I also do believe this is an incredibly hard technical moment. Elli-Tok has nearly no chance of suceeding in building their own algorithm, from square 1, since they don't have access to the ByteDance algorithms. I don't know what access they have to international content and internstional viewing habits, don't know if US content flows to TikTok actual and if they get any algorithmic help from that. This feels like a suicidal business, buying a brand name but lacking any and all of the means to maintain product quality.

There probably are real technical problems here. And feed preferences are probably just gone, while Elli-Tok rebuilds its own perhaps isolated perhaps loosely connected fork, while as said above probably lacking the content and viewer data to work from.

But just as Ellison's bought CBS then let it be overrun & destroyed by the hollow Free Press propogandists (pretending to be neutral, I say as my eyes roll out of my head), I also tend to think they thought they could get away with doing what they want. Maybe they will get away with this project. Maybe it is all isolated US only content, maybe it is swamped with right wing agitprop from here on out. Maybe half those viewers here keep scrolling forever and that's good enough to make the incredibly fantastically rich happy with their US government facilitated acquisition, that sundering an interesting diverse well tuned network is maybe or maybe not a delight but a necessary thing to claw under for this desired class propoganda. But I tend to think they're alas probably smart enough to learn quickly this is not how you boil a frog, and tend to think Elli-Tok is going to (suck for a long while either way, but work to) dial down the right wingism & divisionism a lot, then slowly work it back up.

(But man, watching these buffons mishandle CBS, watching ridiculous bald faced "salute to Mark Rubio" sure makes it hard to believe they have any competence at all.)

Different topic but the extremely critical TikTok v. Garland and the First Amendment Anticanon by Evelyn Douek skewering the unanimous Supreme Court decision that ok'ed this absurd international media property theft is amazing to read. https://papers.ssrn.com/sol3/papers.cfm?abstract_id=6118706

Mouse being jumpy shouldn’t be related to refresh rate. The mouse driver and windowing system should keep track of the mouse position regardless of the video frame rate. Yes, the mouse may jump more per frame with a lower frame rate, but that should only be happening when you move the mouse a long distance quickly. Typically, when you do that, you’re not looking at the mouse itself but at the target. Then, once you’re near it, you slow down the movement and use fine motor skills to move it onto the target. That’s typically much slower and frame rate won’t matter much because the motion is so much smaller.

Reverting to a world without deployed AI is in fact where "normies", that is most people without capital, want to end up.

The current AI promise for them goes something like: "Oops this chittering machine will soon be able to do all you're good at and derive meaning from. But hey, at least you will end up homeless and part of a permanent underclass."

And the people building it are (rightfully) worried about it killing humanity. So why do we have to continue on this course again? An advanced society would at this point decide to pause what they are doing and reconsider.

> TikTok users can't upload anti-ICE videos.

I am responding to the fact US TikTok does not show videos of an armored vehicle driving through a crowd of protesters standing in front of it like the lone man in Tiananmen Square. They are being removed.

This ability to control what information TikTok users are presented with is the reason TikTok was originally banned in the United States.

I am being objective discussion how TikTok is being used as a propaganda tool whether or not I personally agree with China influencing people in South America or whether or not what the United States government is doing to protestors is good or bad. I'm not putting a value on it. I'm pointing out that when I'm in South America and someone links a video in a text message and I start to doom scroll after a while I will start to be introduced to videos of the Unites States government committing violence against Spanish speaking people.

> might be immensely popular in South America

Objectively the current United States regime was hugely popular in Spanish speaking countries like it was in Spanish speaking Florida. Up until a couple months ago, people would tell me how much they support and admire the current regime in the United States. That has changed recently which likely has to do with the content they receive via TikTok which is controlled by the Chinese government which is why it was banned in the United States. After being sold, it is not surprising that the United States is using it the way they accused the Chinese of using it.

That isn't something isolated to Wegmans or even supermarkets.

This[0] image basically says it all, and quality has only further nosedived since 2020.

[0]https://i.ibb.co/Zz2Mb6rF/e0vb5drbeh0e1.jpg

In general, it seems like the pareto products dont exist anymore, the midrange has basically dropped out for daily products and it's been bifurcated. If quality is a scale from 1-100, most places sell a 1, a 10, or you go to an artisanal place for a 90, for exorbitant prices.

But in the past a supermarket or toy store would have sold you an 80 for a reasonable price.

What sucks even more is that for example due to the cacao shortage, lots of products now contain less cacao for the same price. And usually down from 500g/250g to something like 485g/235g. Shrinkflation.

But, when cacao becomes cheaper or inflation stabilizes, companies don't think "let's push the quality back up for the same price", no, they'll pocket the difference. The same is planned to happen if Trump's tariffs get struck down. Businesses will get a huge refund, but the customers that got the costs passed along won't see a penny.

I've been doing vibe code interviews for nearly a year now. Most people are surprisingly bad with AI tools. We specifically ask them to bring their preferred tool, yet 20–30% still just copy-paste code from ChatGPT.

fun stats: corelation is real, people who were good at vibe code, also had offer(s) with other companies that didn't run vibe code interviews.

AI chat interfaces give users power. But it comes at a cost, as users need to:

- Know what they want
- Type it (a pain, specially on mobile)
The HyperChat idea tries to address these by merging chat and web UIs. Links work as user replies, making AI answers feel like webpages (though users can also type anything they want.)

AI UIs are still in their pre-GUI era, with poor discovery and too much typing… Why hasn't something like this been widely adopted yet?
Show HN: Cosmic AI Workflows – Chain AI agents to automate multi-step projects
by tonyspiro | 2026-01-27 18:37:32+00:00
Hi, I'm Tony, founder of Cosmic (AI-powered headless CMS and application development platform). We kept running into the same problem: create a blog post with the help of an AI agent, use the output for another prompt to create social posts, then manually post to X, LinkedIn, Facebook. Every single time.

So we built AI Workflows — chain multiple agents together and let them run autonomously, with each step receiving outputs from previous steps.

Three agent types you can chain:

- Code Agents: Build features in GitHub with commits and pull requests.

- Content Agents: Generate CMS content with context injection from previous steps.

- Computer Use Agents: Automate browser workflows and record demos.

How it works:

1. Define steps with agent type, prompt, and configuration

2. Steps run sequentially or in parallel (configurable)

3. Context passes automatically between steps

4. Trigger manually, on a schedule (cron), or via CMS and API events (object.created, object.edited, etc.)

5. Add approval gates for human review before critical steps

Example: Autopilot feature development:

Step 1: Content Agent writes a feature spec based on user feedback

Step 2: Code Agent builds the feature, creates PR, and deploys to production

Step 3: Content Agent generates documentation and a changelog entry

Step 4: Computer Use Agent posts update to team Slack with the PR link and preview URL

Currently in beta. Would love feedback on the workflow model and what use cases you'd want to automate.

As for the ban on Jews by some Arab / muslim countries - remember that the west was actively encouraging Jews, with zionist movements all over the world, to migrate to the middle-east any occupy muslim-Arab land. Sure, it began with a narrow focus with only Palestine. But who knew where it would stop if it was successful? Most of these countries are former western colonies who immediately understood what the west was trying to do by sending foreign Jews to occupy their land - the "divide and rule" policy was how they were subjugated too in the first place, to become colonies, and the newly independent Arab states understood that by driving Jews to the middle-east, their former masters wanted to use the Jews to foment a conflict between Jews and Muslims which they could then use to break the newfound unity amongst the Arab states and use as an excuse for interventionist politics. It had (and still has) nothing to do with antisemitism and everything to do with making sure that former imperialists doesn't exploit any political vulnerability in their country and endanger their (then) newfound independence.

Claude and Codex are CLI tools you use to give the LLM context about the project on your local machine or dev environment. The fact that you're using the name "ChatGPT" instead of Codex leads me to believe you're talking about using the web-based ChatGPT interface to work on a large codebase, which is completely beside the point of the entire discussion. That's not the tool anyone is talking about here.

The argument is that people who are born outside and come in, but instead of embracing our ideals, seek to do America harm, import bad ideals (like misinformation in the case of Murdoch, hunting innocents in the case of Karp, and racism in the case of Musk), should be called out and shamed. Fox News and ICE have done great damage largely enabled by the infra these immigrants set up. They also seem to promote hate against other immigrants (Chinese, muslims, etc). I think we often do not call out Musk and Murdoch for the damage they did. And given they are not American by birth, I do question their loyalties because their actions reflect a willingness to siphon money out of America and do us harm.

I find personally that this is the biggest advantage of Rust for the kind of code I write. Memory safety is great and all, but an aggressive GC would do just fine for what I tend to work on.

But the culture around Rust is such that libraries on average tend to be of much higher quality - more correct, better APIs, more assumptions encoded into the type system rather than punted to runtime, etc.

It's important to understand that he's talking about a specific set of models that were release around november/december, and that we've hit a kind of inflection point in model capabilities. Specifically Anthropic's Opus 4.5 model.

I never paid any attention to different models, because they all felt roughly equal to me. But Opus 4.5 is really and truly different. It's not a qualitative difference, it's more like it just finally hit that quantitative edge that allows me to lean much more heavily on it for routine work.

I highly suggest trying it out, alongside a well-built coding agent like the one offered by Claude Code, Cursor, or OpenCode. I'm using it on a fairly complex monorepo and my impressions are much the same as Karpathy's.

Guns on planes aren't terribly effective. Firstly cause puncturing the hull will end badly.

But also because there's a lot of people in a very confined space. A shooter has no space to maneuver and threats on all sides.

It's not even heros-required. Most passengers know the math. Hijacking means certain death anyway, so you may as well roll the dice.

IMO, this isn't entirely a "new world" either, it is just a new domain where the conversation amplifies the opinions even more (weird how that is happening in a lot of places)

What I mean by that: you had compiled vs interpreted languages, you had types vs untyped, testing strategies, all that, at least in some part, was a conversation about the tradeoffs between moving fast/shipping and maintainability.

But it isn't just tech, it is also in methodologies and the words use, from "build fast and break things" and "yagni" to "design patterns" and "abstractions"

As you say, it is a different viewpoint... but my biggest concern with where are as industry is that it these viewpoints aren't equally valid "different ways" of building software... it is quite literally different stages of software, that, AFAICT, pretty much all successful software has to go through.

Much of my career has been spent in teams at companies with products that are undergoing the transition that "hip app built by scrappy team" to "profitable, reliable software" and it is painful. Going from something where you have 5 people who know all the ins and outs and can fix serious bugs or ship features in a few days to something that has easy clean boundaries to scale to 100 engineers of a wide range of familiarities with the tech, the problem domain, skill levels, and opinions is just really hard. I am not convinced yet that AI will solve the problem, and I am also unsure it doesn't risk making it worse (at least in the short term)

After successfully getting Xamarin acquired by Microsoft, apparently he got disappointed how everything turned out, especially the decisions that lead to the Xamarin.Forms to MAUI rewrite, MonoDevelop being killed, or what is left of Mono/Xamarin.

If you have a ChatGPT account, there's nothing stopping you from installing codex cli and using your chatgpt account with it. I haven't coded with ChatGPT for weeks. Maybe a month ago I got utility out of coding with codex and then having ChatGPT look at my open IDE page to give comments, but since 5.2 came out, it's been 100% codex.

I think you mean a Poisson process rather than a Poisson distribution. The Poisson distribution is a discrete distribution on the non-negative integers. The Poisson process’s defining characteristic is that the number of points in any interval follows the Poisson distribution.

There have been a large variety of point processes explored in the literature, including some with repulsion properties that give this type of “universality” property. Perhaps unsurprisingly one way to do this is create your point process by taking the eigenvalues of a random matrix, which falls within the class of determinantal point processes [1]. Gibbs point processes are another important class.

I enjoy both and have ended up using AI a lot differently than vibe coders. I rarely use it for generating implementations, but I use it extensively for helping me understand docs/apis and more importantly, for debugging. AI saves me so much time trying to figure out why things aren’t working and in code review.

I deliberately avoid full vibe coding since I think doing so will rust my skills as a programmer. It also really doesn’t save much time in my experience. Once I have a design in mind, implementation is not the hard part.

> Further, when you don’t have to drive 20-30 mins to go to a grocery store but the stores you need are within a 5 min walk,

Once you get used to have everything at a walking distance, you wonder how you could put up with having to drive to a supermarket.

Two are the main advantages.

The first is that you don't need to plan much in advance. Want to make hamburger tonight ? Cross the street, get meat from the butcher, get a couple of tomatoes and salad from the grocery store and the bread, and you are ready to go. I used to shop once a week and I had to have an idea of what I wanted to cook every day for the whole week.

The second is that this way you regularly eat really fresh food. My shopping list is always stuff like "two tomatoes", "three apples", "fish for tonight", "a loaf of bread". My fridge is mostly empty.

humans have a unique capacity to reduce suffering in a way

With low cost to our wellbeing as well. Which I think is the main point. Our advances in logistical transportation and food production allow us to be kinder and more plentiful than ever before. Unfortunately we see "instinctual" echoes of past strife seemingly arise from minor inconveniences (those ppl do something that annoys me).
