You appear to be parroting the nonsense from Collier's "I hate Feynman" videos. Feynman gave the FLP lectures at Caltech, which were recorded and photographed, but at that time there was no intention of making them into a book. Leighton and Sands (with the help of some secretaries and grad. students) transcribed these lectures, and then lightly edited them, for use by Caltech students as study notes. These fell into the hands of publishers a couple years later, and they were the ones who proposed turning them into a book. I am now the Editor of those books. To say Feynman "didn't write" FLP may be true in the most literal sense that he did not set pen to paper, but the content is his, as you can easily verify by going to The Feynman Lectures Website, where you can listen to the recordings and see the photos of the original lectures and compare them to the book - they are the same, except for very minor changes that would be required to make any spoken lecture readable.

> the worst case scenario is really mild: A new version of windows comes out, breaking ntdll compatibility. Zig project adds a fix to the std lib. Application developer recompiles their zig project from source, and ships an update to their users.

The ~only good thing that programmers have achieved in the past ~60 years has been Windows stability.

Create a popular programming language, and then make programs written in it not run on newer Windowses is just something else. I so hate this.

Was "robust, optimal and reusable" always "run an older Windows on your newer Windows to run Zig software"?

Because so much technical functionality has been lost/paywalled/dark patterned/enshitified, I've cut the number of apps I use. I've realized building core personal functionality around the whims of corporations eventually just gets weaponized against me, so I might as well start undoing that on my own terms. Who in 2026 is really bringing in a new app/Saas to do much of anything like we naively did a decade ago? No one I know, we've been shown we will be treated as suckers for doing that.

This is the thing a lot of skeptics aren't grappling with. Software engineering as a profession is mostly about building software that can operate at scale. If you remove scale from the equation then you can remove a massive chunk of the complexity required to build useful software.

There are a ton of recipe management apps out there, and all of them are more complex than I really need. They have to be, because other people looking for recipe management software have different needs and priorities. So I just vibe coded my own recipe management app in an afternoon that does exactly what I want and nothing more. I'm sure it would crash and burn if I ever tried to launch it at scale, but I don't have to care about that.

If I was in the SaaS business I would be extremely worried about the democratization of bespoke software.

It's not fully applicable here, but industry standard DSLs also stick around because non-programmers find learning it a good investment.

I have a business analytics friend that knows SQL because it's part of his workflows.

But Excel, Notion, Power BI, and other low/no-code tools all have their own data filtering and transformation languages (or dialects). He'd rather spend his time learning more about his line of business, than an aspect of yet another cloud tool that gets forced on him.

>> If it does, it's a pyrrhic victory. You'll complete the destruction of everything the Democrats claim to defend.

No, empathy. And a country were people more-or-less get along, even if they disagree, instead of one of hateful factions engaged in bitter battle for power and dominance.

>> Has Donald Trump corrupted you, turning you into your own kind of fascist?

> You do not know what fascism is. Educate yourself.

Read more carefully. I said your own kind of fascist, as in drawing parallels to bad behavior that you understand, in an attempt to get to see it in a different light.

>> FYI, that's what one kind of mindless hate looks like to the hater.

> Good try. "You hating racism makes you the real racist". FFS.

"FFS," read more carefully. Do you think racism is the only kind of hate?

> Trump in light of the overwhelming evidence to his pedophilia.

Please share the New York Times article with that bombshell, so succinctly stated. I must've missed that one.

> Overall, good attempt at the classic "anti-fascism is the same as fascism". We're done talking.

Actually it wasn't an attempt at that at all.

But you're right, we're done talking. You seem to seem to be retreating into an angry defensiveness of your Trump-like tendencies, and resorting to pretty blatant distortions to [checks notes] resist the idea of having empathy for others.

> Things like sanitizers largely rely on test coverage.

And not in a trivial “this line is traversed” way, you need to actually trigger the error condition at runtime for a sanitizer to see anything. Which is why I always shake my head at claims that go has “amazing thread safety” because it has the race detector (aka tsan). That’s the opposite of thread safety. It is, if anything, an admission to a lack of it.

Because the FDA and indeed the Trump administration wants to aid "Wellness" grifters and influencers, and to push "medical freedom". That way, people with a legal obligation to be ethical aren't in the loop. Conspiracy theorists can drink bleach and take ivermectin. When anyone calls them out as dipshits, Conspiracy theorists can retort "that's just your opinion".

Peer relays are a bit different from our previously available Custom DERP servers. While the custom DERPs do relay traffic, they also require a bunch of configuration and management for their other jobs and they open up availability concerns that are pretty tough for our average customer.

Conversely Peer Relays are built on top of the shoulders of DERP. For example, they don't need to do peer discovery set connections up end to end - instead connections are brokered via our DERP fleet and then in a sense "upgraded" to an available Peer Relay or Direct connection. Because of that they're super lightweight and much easier to deploy + manage. And, they scale horizontally so you can deploy many peer relays across your network, and they're resilient to downtime (we'll just fall back to DERP).

How would you call something like Claude or ChatGPT then, or even some image classifier from 20 years ago?

Just answering because I first wanted to write "software" or whatever.

I used to find gamers calling their PC "machine" hilarious.

However, it is a machine.

And for AI chatbots, I used the word for lack of a better term.

"Software" or "program" seems to also omit the most important part, the constantly evolving and intransparent data that comprises the machine...

The alogorithm is not the most important thing AFAIK, neither is one specific part of training or a huge chunk of static embedded data.

So "machine" seems like a good term to describe a complex industrial process usable as a product.

In a broad sense, I'd call companies "machines" as well.

So if the cringe makes you feel bad, use any word you like instead :D

Yes, but you’d be foolish to realize your gains if you think the stock still has a long way to run. That just triggers taxes and eliminates any further upside. So, we can reasonably conclude that either BH thinks Amazon’s run is nearly exhausted, or it’s one of the stocks with minimal forward prospects in BH’s portfolio and they want to deploy the capital with something that they feel will have a greater return (maybe Amazon still rises, but whatever else they want to invest in they think will rise more/faster).

That's my hope, too, since I've had the unfortunate luck of practically being forced to fulfill my lifelong dream and create a software company as a solo dev in 2025. Great timing...

However, I've gotten doubts about the value of creativity and having a vision. Plenty of people have great creativity and a fantastic vision, and we can see already how AI allows people to churn out interesting and useful projects at much faster pace than just a few years ago. The problem is that it seems more and more impossible to actually make a living of that.

Anybody with the money to have access to enough AI will be able to create a clone of software X. We might not be there quite yet but it's just a matter of time. That seems to be a death sentence for any small software business.

I liked the simplistic UI, but it is not quite ready for serious use.

I tried using it on a simple svg that i had (around 1KB, just few simple lines and shapes). But it did not rendered them properly. Colors were off (black-box instead of original colors), and in one place it was showing at triangle instead of an L shaped line.

Also when I move an object, a single Cmd+Z wont undo the action. Have to repeat twice for object to go back (I am using Chrome on macbook)

I still want to know the definition of a world model, because it seems that what they are doing now is a very basic model of GS (not sure if it is self-developed) and a GS browser.
by scottyah | 2026-02-18 18:33:56+00:00
It's certainly not true yet, but LLM abilities now vs two years ago leads really makes you think. It may not be easy to replicate all you do, but new entrants could easily just go after the highest margin parts of your business. Why try to tackle All the countries and browser configs when you can get 90% of the profitable ones, and just address that part of the market?

i.e. Apple does a ton of work to ensure I'm paying taxes and complying with laws in hundreds of places I'll probably never make a sale in. Sure, some high paying people might need all of that, but I'd be happy with just USA. I only utilize the other parts because it was a few clicks.
by IggleSniggle | 2026-02-18 18:35:00+00:00
Depends. Within the US, there are data export laws that could make the "whoever" part illegal. There are also conspiracy to commit a crime laws that could imply liability. There are also laws that could make performing/demonstrating certain exploits illegal, even if divulging it isn't. That could result in some legal gray area. IANAL but have worked in this domain. Obviously different jurisdictions may handle such issues differently from one another.
by lysace | 2026-02-18 18:35:32+00:00
How do you handle the do-before-thinking devs? Or the kinda low-to-mid performing devs? Most companies has one or a few of those, right? They help the company machine go around by doing the somewhat boring stuff over and over again.

Tailscale in a company/developer env seems awesome when you know what you are doing and (potentially) terrifying otherwise.

Does someone set up detailed ACLs for what's allowed? How well does that work?
Show HN: Porchsongs: AI to create and catalogue personalized songs
by river_otter | 2026-02-18 18:35:33+00:00
Hi, Nathan here, I’m an MLE at Mozilla.ai, and also a guitar player. I have a small front porch at my house and I love to sit out there in the summer and play songs on my guitar. There are some songs that have amazing melodies, but their lyrics aren’t as relevant for me to sing. For example, I’m a new parent and there’s an awesome Luke Combs album about his relationship with his son, but the songs use imagery all about country themes like trucks and hunting, which aren’t relevant to me as a software developer that likes raspberry pi’s and road cycling.

I thought “Man it would be great if I could use an LLM to help me just slightly tweak the songs to make it more relevant for me without it messing up the rhythm or melody”.

A year ago I tried something like this and the LLMs rewrites were real cheesy, but I did it now with Claude Opus 4.6 and oh boy let me tell you, Opus is an insanely good lyricist.

I played for my wife the song Opus and I wrote based off of a Luke Combs song, and it made her cry. There was something special about writing a song that has personal meaning, but getting a boost from AI to make it sound not-cheesy.

So thus was born porchsongs: an application that connects you with a LLM to help you rewrite song lyrics as much as you like, and then stores the charts in a library so you can play them and keep iterating on them if you'd like

Step 1: Find the chord chart or lyrics etc of the song you like via ultimateguitar.com
Step 2: Chat with the LLM to workshop the song lyrics until you’re happy with it
Step 3: Play the songs and enjoy the personalized lyrics

Right now you deploy it as a docker service yourself, I have a simple auth set up but it's meant for you to self host, not really a distributed application for multiple people to be creating accounts etc.

I hope you get as much joy from this as I already have.

> Amazon's core business does not make sense. Despite being so massive, their retail operation makes almost no money.

Net profit margins for retail are only around 3% across the industry.

Amazon isn't actually doing anything unusual in that regard. Retail is just a very low profit margin business whether it's physical or online.

These numbers are always confusing to those of us in the tech world where SaaS net profit margins are always very high.

Brian Cugelman’s "12 Emotional Journeys of Color Psychology" breaks down how color influences user perception and behavior through a structured, neuroscience-informed framework. Rather than textbook color meanings, it defines 12 emotional journeys people take in digital experiences and shows how color can support those transitions in context. It’s a practical lens for product and UX folks who want to move beyond ‘blue = trust’ and tie color choices to real emotional motivators and reinforcers.

There used to be a time in history when a system administrator had to know all this shit in order to keep their job. I guess nowadays devops just means dev as we furiously pump tokens into the AI Wurlitzer whenever we dont know how to do something and hope it doesnt gaslight us into deleting prod.

Thanks, that sentence made my day.
Show HN: Emotional photoreal AI humans at $0.06 / min
by kraddypatties | 2026-02-18 18:36:47+00:00
Hey HN, we're the co-founders of Keyframe Labs. We train photoreal AI human models you can FaceTime with (try for yourself here: https://demo.keyframelabs.com). Notably, our models run at 60fps on a single consumer GPU (4090).

Today we're shipping our new model, persona-1.5-live, the first to achieve both photorealism and emotion at conversational latency. We see this as a significant step toward passing the "Turing test" for video agents.

Here's an unedited demo video of a conversation between Cosmo and one of us: https://www.loom.com/share/406534ea9991458cb64030df02e565de

You can also FaceTime Cosmo yourself here: https://demo.keyframelabs.com. Try asking him for a sad Shakespearean monologue. Or for a "funny" dad joke.

Voice has emerged as a primary conversational interface across industries, and we think video is the next leap. In our early pilots, face-to-face interaction drives measurably better outcomes in things like sales training and language learning.

Our constraints from day one have been:

- Make meaningful progress towards beating the uncanny valley

- Run at real-time, with world-scale efficiency

In training persona-1.5-live, we didn't have access to giant clusters or hyperscaler budgets. This forced quite a bit of innovation in how we approached diffusion:

- An aggressively lightweight architecture

- Training tricks to squeeze signal out of limited data

Perhaps the most surprising finding was that, for our problem space, representation quality can be an viable substitute for scale. We spent an inordinate amount of time crafting a from-scratch latent space for persona-1.5-live to keep identity and emotion stable given our compute and data constraints.

The result: photoreal AI humans with emotion and real-time latency, priced at just $0.06 per minute.

If you're interested in building with our API, see the docs here: https://docs.keyframelabs.com. It's free to get started.

Excited to see what y'all think!

I'm running Fedora Silverblue as my host OS, this is the kernel:

$ uname -a
Linux fedora 6.18.9-200.fc43.x86_64 #1 SMP PREEMPT_DYNAMIC Fri Feb 6 21:43:09 UTC 2026 x86_64 GNU/Linux

You also need to set a few kernel command line paramters to set it up to allow it to use most of your memory as graphics memory, I have the following in my kernel command line, those are each 110 GiB expressed in number of pages (I figure leaving 18 GiB or so for CPU memory is probably a good idea):

ttm.pages_limit=28835840 ttm.page_pool_size=28835840

Then I'm running llama.cpp in the official llama.cpp Docker containers. The Vulkan one works out of the box. I had to build the container myself for ROCm, the llama.cpp container has ROCm 7.0 but I need 7.2 to be compatible with my kernel. I haven't actually compared the speed directly between Vulkan and ROCm yet, I'm pretty much at the point where I've just gotten everything working.

In a checkout of the llama.cpp repo:

podman build -t llama.cpp-rocm7.2 -f .devops/rocm.Dockerfile --build-arg ROCM_VERSION=7.2 --build-arg ROCM_DOCKER_ARCH='gfx1151' .

Then I run the container with something like:

podman run -p 8080:8080 --device /dev/kfd --device /dev/dri --security-opt seccomp=unconfined --security-opt label=disable --rm -it -v ~/.cache/llama.cpp/:/root/.cache/llama.cpp/ -v ./unsloth:/app/unsloth llama.cpp-rocm7.2 --model unsloth/MiniMax-M2.5-GGUF/UD-Q3_K_XL/MiniMax-M2.5-UD-Q3_K_XL-00001-of-00004.gguf --jinja --ctx-size 16384 --seed 3407 --temp 1.0 --top-p 0.95 --min-p 0.01 --top-k 40 --port 8080 --host 0.0.0.0 -dio

I am not so sure this is an accurate analysis? Notably, a major thing that kept it so that retail made no money, was the massive expense of expanding the retail operations. That is, expanding retail footprint is a massive cost. And you have to expand if you want to reach more customers.

This is different from AWS where your reach is essentially "all of the internet" for anything that you launch. But this really just meant that reinvesting the revenue from AWS was harder for them to do, compared to revenue from retail. As a result, they didn't. Not nearly as aggressively.

I don't share the Amazon hate everyone has, I've had very good experiences with Amazon retail. But I do sometimes try to spread out my purchases to other vendors due to monopoly concerns.

It's amazing how many times you buy direct from a vendor and then it comes via Fulfilled by Amazon.

The other issue is when anything goes wrong I've had a hell of a time with some vendors. It's a crapshoot - some vendors ship quickly and competently, and handle customer service like returns quite well. Others you might end up with your product not even shipping for a week much less arriving, even though the store says "in stock ships tomorrow". Due to this, when I really must have something on time or if it's a risky purchase I have a good chance of needing to return I tend towards just getting it with Amazon.

A lot of smaller shops simply don't want to deal with logistics and customer service - it's hard to compete on Amazon for shipping costs. And warehouse/returns/etc. is just a nightmare for a small shop. I absolutely understand why a small speciality manufacturer with a few dozen low volume SKUs would prefer to just use FBA and be done with it.

This sounds like an awful experience and I feel bad for the little girl that had to go through that.

Having said that, what should the penalty for overstaying a visa by ~7 years[1] be? Nothing? I'd love to see the Democrats propose an alternative approach here, but all I seem to hear is thought terminating cliches like "no one is illegal". Is the proposed alternative just open borders?

I have the same fears. Last year they have publicly stated they are not interested in acquisition [0]

> Pennarun confirmed the company had been approached by potential acquirers, but told BetaKit that the company intends to grow as a private company and work towards an initial public offering (IPO).

> “Tailscale intends to remain independent and we are on a likely IPO track, although any IPO is several years out,” Pennarun said. “Meanwhile, we have an extremely efficient business model, rapid revenue acceleration, and a long runway that allows us to become profitable when needed, which means we can weather all kinds of economic storms.”

Nothing is set in stone, after all it's VC backed. I have a strong aversion to becoming dependent upon proprietary services, however i have chosen to integrate TS into my infrastructure, because the value and simplicity it provides is worth it. I considered the various copy cat services and pure FOSS clones, but TS are the ones who started this space and are the ones continuously innovating in it, I'm onboard with their ethos and mission and have made use of apenwarrs previous work - In other words, they are the experts, they appear to be pretty dedicated to this space, so I'm putting my trust in them... I hope I'm right!
