Other comments here (so far) don't seem super happy with this, but I can't help think this is a good thing primarily because of this:

"The fediverse feed isn’t algorithmically ranked, or subject to any of Threads’ rules or moderation; it’s just a reverse-chronological feed of stuff you follow."

That's great! Any step we can take away from ultra-algorithimically-optimized feeds, the better, I think. Normalize reverse-chronological feeds again.

It brings into question, does the concept of a Fediverse subvert having a variety of communities with different cultures?

Imagine putting the Meta/Twitter/Reddit world behind you, posting on Bluesky/Mastodon, and then your content is showing up on Threads next to influencer garbage, AI slop, culture wars, crypto spam, pillow ads.

And just as bad or worse, content from those places flooding your parachute community. Those sites function best now as quarantine.

Apple also arbitrarily drops OS support on devices. On mobile devices they used to be the leading edge, but on desktop they end support faster than Microsoft does. Microsoft guaranteed 10 years of support when Windows 10 launched, but Apple is dropping support for their 2020 Intel Macs after this year. Plus, in terms of "1984", Apple's notarization system is as bad as it gets, and it's even harder to turn off than Windows Smartscreen.

Apple does have better speakers, though. So that's a nice plus.

> unbelievable how we have a level of autonomy here and now, and not too many people know about it

Would note that most premium cars sold in America currently have advanced self-driving capabilities. I've personally been more impressed by Mercedes' kit than Tesla's, mostly because the former seems to have done a great job of defining where you can almost trust the system to just work.

I'd be interested to see those studies. I think there could be a couple different types of tolerance, one of which only occurs with rather heavy use. It's something I've seen reported anecdotally from a number of people who've used psychedelics very heavily. It might not show up in human studies because of ethical concerns. There could be some interesting pharmacological differences too, where this only occurs with specific drugs. The psychedelics are quite varied in terms of pharmacodynamics beyond just the 5-HT-2 receptor subfamily.
Show HN: I built a FOSS tool to run your Steam games in the Cloud
by pierrebeucher | 2025-06-17 18:57:19+00:00
I wanted to play my Steam games but my aging PC couldn’t keep up, so I built Cloudy Pad - a tool to run Steam in the Cloud (GitHub: https://github.com/PierreBeucher/cloudypad)

It runs on AWS, Azure, GCP, Scaleway and Paperspace with various cost optimizations and safeties:

- Cost alerts

- Auto stop inactive instances to avoid unwanted cost

- Disk snapshots and data cleanup for cost efficiency

- Spot instance support

Under the hood: a Linux VM and a container running Sunshine (a streaming server https://github.com/LizardByte/Sunshine) with Steam. Most Windows games work just fine thanks to Proton.

It streams effortlessly at 1080p 100+ FPS - I recently played Baldur’s Gate III and Clair Obscur in Ultra, ran like a breeze.

Cost-wise it’s great for occasional players: ~30h or less per month typically cost less than 25$. Though admittedly for heavy gamers it may be less cost-effective due to cloud pricing.

I’d love feedback from the HN community !

AV1's advantage narrows to ~5% over H.265 at very high data rates, in the same way that MP3 at 320 kbps is competitive with AAC at 320 kbps. But AV1 is never worse than H.265 from a VMAF/PSNR perspective at any bitrate, and of course H.265 is heavily patent encumbered in comparison. https://chipsandcheese.com/p/codecs-for-the-4k-era-hevc-av1-...

I heard that before. Borland Delphi, Microsoft FrontPage, Macromedia Flash and so on. I learned how in 5 years or so, these new technologies would dominate everything.

Then I learned that two scenarios exist. One of them is "being replaced by a tool", the other is "being orphaned by a tool". You need to be prepared for both.

currently i am coding a node/react/ts firebase app that allows dynamic multiagent workflows to automate content workflows (a workflow.json defines call this model and the pass this part of the output of that model to that model and then combine it with this model to do that)

my setup is claude code in yolo mode with playwright MCP + browser MCP (to do stuff in the logged i firebase web interface) plus search enabled.

the prototype was developed via firebase studio until i reached a dead end there, then i used claude code to rip out firebase genkit and hooked in google-genai, openai, ...

the whole codebase goes into google gemini studio (caus the million token window) to write tickets, more tickets and even more tickets.

claude code then has the job to implemt these tickets (create a detailed tasklist for each ticket first) and then code it until done. end of each tasklist is a working playwright end to end test with verified output.

and atomic commits.

i hooked anydesk to my computer so i can check i at some point to tell to to continue or to read Claude.md again (the meta instructions which basically tells it to not to fallbacks, mock data or cheat in amy other way.)

ever fourth ticket is refactoring for sinplicity and documentation.

the tickets mist be updated before each commit and moved to the do done folder only when 100 tested ok.

so yeah, when i wale up in the morning either magic happend and the tockets are all done. or it got stuck and refactores half the codebase. in that case it works for an hoor to go over all git commits to find out where it went wrong.

what i need are multiple coding agent which challenge each other at crucial points.

I think it's a mix of set and setting combined with people who have probably never taken any kind of drug aside from alcohol and maybe infrequent cannabis usage. People who take LSD "many times" usually come to it after already being able to handle themselves on some psychedelic substance, so the experience is less all-encompassing and more mundane. Some priest who's never even been contact high, sitting in a room with religious iconography and being prepped to experience something spiritual, seems likely to have a very different experience.

I've been curious about what the best way to recording breathing rates with wearables would be. Thought was a chest strap with springs to measure tension with higher tension being air in lungs. But you're talking about a different way. How does the magnet work to get rates? I'd want something that can get rates and volumes from mouth vs nasal and also tell which vent the air in coming into the lungs from. Probably a case of how much intrusion you want vs how intricate and correct the data is.

> HEIC is good, as long as you pinky promise to never ever leave Apple's ecosystem, ie HEIC sucks.

Not really true in my experience, I have no problems using it in Windows 11, Linux, or with my non-Apple non-Google cloud photos app.

The iPhone using it in an incredibly widespread way has made it a defacto standard.

If you're having trouble in Windows, I wonder if you're running Windows 11 or 10? Because 11 seems a lot better at supporting "modern things" considering that Microsoft has been neglecting Windows 10 for 3 years and is deprecating it this year.

This article remains one of the better pieces on this topic, especially since it clearly defines which definition of "AI agents" they are using at the start! They use: "systems where LLMs dynamically direct their own processes and tool usage, maintaining control over how they accomplish tasks".

I also like the way they distinguish between "agents" and "workflows", and describe a bunch of useful workflow patterns.

I published some notes on that article when it first came out: https://simonwillison.net/2024/Dec/20/building-effective-age...

A more recent article from Anthropic is https://www.anthropic.com/engineering/built-multi-agent-rese... - "How we built our multi-agent research system". I found this one fascinating, I wrote up a bunch of notes on it here: https://simonwillison.net/2025/Jun/14/multi-agent-research-s...

Taking another look, I see four little rectangles that seem to match the risers close to the camera at the landing, but far from the rocket. I think they may have actually retracted. That would be neat.

It makes more sense than someone going out and grabbing them during the short flight. Those things would need to be sturdy and attached to not melt or blow away during the launch, and they would be hot.

edit: If you open up the first image on the submission and look to the left of the crane, you can see what look like the risers. They do seem to come out of the ground. You can see the same trees as the landing shot.

edit: I didn't realize the page had more videos under the Download button. I was wrong about the rectangles, but you can definitely see it's landing in a different spot in the onboard video (#3). You can still see the risers when it lands.

A funny detail about this is that Feynman hadn't bothered to budget the $1000 for the prize. He thought someone would have to invent new tech to build the motor which would take years. If he had just gone a little smaller, say 1/100th of an inch instead of 1/64th, he might have gotten his wish.

Despite his disappointment he did keep his word and pay the prize. His wife was not happy.

Windows LTSC can cause problems with some software, though, as some components and services aren't installed or loaded by default. Plus, licenses are expensive as hell.

If you want to save a buck or are going to pirate the OS anyway, stick with the normal Windows 10 updates first and then downgrade to the stripped-down LTSC versions when that runs out in late 2027.

It is possible I misread or misunderstood something on the topic with regards to compensation for grid services in the article. With that said, before jumping to solutioning (although I am a strong proponent of batteries based on their performance, capabilities, and cost as of this comment), I would like to see more information and data as to which generators were signaled to change their output when the grid started to fault and were unable or unwilling to (failure to appropriately manage output and/or field excitation to absorb reactive power, etc) and if improvements to the electricity market are required. Without root cause, we cannot effectively solve.

You can find good contract on Upwork, but you need to go through lots of bad ones. I find around 5 good contracts there per year. I find that even when a client agrees on a rate, Upwork has the reputation of finding inexpensive workers, and you will get many clients trying to pay you less.

I'm also a bit tired of running into people that are 'starting a contracting firm' and have 0 clients or direction yet and just want to waste your time.

> Just as there is a clear winner for video - av1 - there seems to be nothing in the way of "this is clearly the future, at least for the next few years" when it comes to encoding images.

Say what? A random scan across the internet will reveal more videos in MP4 and H.264 format than av1. Perhaps streaming services have switched, but that is not what regular consumers usually use to make and store movies.
Show HN: lambda-nat-proxy – Serverless proxy using Lambda and UDP NAT punching

Revisited an old experiment of mine (https://github.com/dan-v/awslambdaproxy): can AWS Lambda functions work as network proxies? This time using UDP NAT hole punching + QUIC tunnels.

Client discovers public IP via STUN, writes session data to S3, which triggers a Lambda. Both endpoints punch UDP holes through their NATs, then establish a QUIC connection for encrypted traffic forwarding.

One of my favorite AI How-tos in the last year. Barry and Erik spend 80% of the post saying ~”eh, you probably don’t need agents. Just build straightforward deterministic workflows with if-statements instead.”

And then, when you actually do need agents, don’t over complicate it!

This post also introduced the concept of an Augmented LLM — a LLM hooked up to tools, memory, data — which is a useful abstraction for evolving LLM use beyond fancy autocomplete.

“An augmented LLM running in a loop” is the best definition of an agent I’ve heard so far.

Could this moment finally be the thing that finally sinks Tesla's ridiculous stock price?

As long as the Robotaxi is just and idea, it can't fail. Once it's real, people can realize what a joke it is.

Relevant Silicon Valley:

"If you show revenue, people will ask 'HOW MUCH?' and it will never be enough. The company that was the 100xer, the 1000xer is suddenly the 2x dog. But if you have NO revenue, you can say you're pre-revenue! You're a potential pure play... It's not about how much you earn, it's about how much you're worth. And who is worth the most? Companies that lose money!"

I have had the exact opposite experience. I have been using FSD on HW3 for a few years and the latest version for me is much safer than me driving. I dont care about your opinions of him killing the brand, they are irrelevant. It's clear that the vision only approach will work, it may need more training data but it will get there. Good luck with your short!

Last I checked there were 35K fatal accidents in the US every year - if FSD can bring that down to 3.5K that will be an obvious win.

And thats why you guys are working with computers and not people, cause that's pretty rude. What they are doing is only rude if they are aware that it annoys people. You response is rude nonetheless since it's a version of "that'll teach them" which is a pretty immature way of handling disagreements or conflicts.

A more mature way would be for "first offenders" to politely reply hi and help them with whatever they need and then when everything is done politely point out that asking directly would be better next time, perhaps with a link to some version of nohello.net. With "repeat offenders" sure, go ahead with what you are doing.

> does it qualify for antitrust review and possible action?

Remember, in the US, it's not actually illegal to be a monopoly. What's illegal is unfairly leveraging your monopoly position (things like threatening suppliers if they do business with a competitor, etc.)

Is SpaceX doing that sort of thing? I don't know, but I bet potential competitors are constantly assessing that.
by Tuna-Fish | 2025-06-17 19:02:28+00:00
They do throttle, and quite low compared to other comparable engines, but they still cannot throttle an engine below 1 TWR when the stage is near empty. Meaning that they cannot hover a stage, either the engine is on and the stage is accelerating upwards, or it's off and it's accelerating downwards. (And you cannot rapidly turn engines on and off.)

So they need to "hoverslam", that is, arrive at the landing pad rapidly decelerating so that their altitude hits zero just as their speed hits zero. This was thought to be very hard, but I don't think SpaceX has lost a stage due to estimation failure there. It helps that there is significant throttle range and fairly rapid throttle response on the engines, so they can have some slack. (Plan to decelerate at 2.5g for the last ~20s or so, with the ability to do anything between ~1.5g to 4g, so you can adjust throttle based on measured landing speed.)

Their Superheavy has more engines, allowing them to bring the TWR below 1, enabling hovering.

This is where switching costs matter. Take Google Maps, many people can’t switch to another app. In some areas, it’s the only app with accurate data, so Google can degrade the experience without losing users.

We can tell it’s getting worse because of UI changes, slower load times, and more ads. The signs are visible.

With LLMs, it’s different. There are no clear cues when quality drops. If responses seem off, users often blame their own prompts. That makes it easier for companies to quietly lower performance.

That said, many of us on HN use LLMs mainly for coding, so we can tell when things get worse.

Both cases involve the “boiling frog” effect, but with LLMs, users can easily jump to another pot. With traditional software, switching is much harder.

"not a rules problem"

I beg to differ.

The only difference between your run of mill solar/battery inverter and a grid forming inverter is ... software. Source NREL: https://docs.nrel.gov/docs/fy24osti/90256.pdf

Grid connected inverter software has to follow mandated rules defined by the grid managing organisation, otherwise it's simply illegal to connect it to the grid.

So if there are issues related to the behaviour of the grid connected inverters, except for bugs, mismanagement or hardware failure, it's 100% the fault of the grid managing organisation.

Inverters can provide grid stability if and only if the grid managing organisations allows it by putting in place rules and market mechanisms for it.

Hardware transcoding still involves software, plus the hardware itself can be vulnerable. It's not meant to act as security. But anyway, it's also very hit-or-miss. The drivers need to support it, and even then the software might not use it.

One random thing that ticks me off, Google Meet insists on using VP8/VP9 because they invented it, which has way less overall support for hardware transcoding. That's why it uses so much more CPU on many devices than Zoom etc which use the more common H.264.

I haven't tested o3-pro yet enough to have a good hierarchy of confabulation.

I use AI a lot to double check my code via a code review what I've found is

Gemini - really good at contextual reasoning. Doesn't confabulate bugs that don't exist. Is really good at finding issues related to large context. (this method calls this method, and it does it with a value that could be this)

Sonnet/Opus - Seems to be the more creative. More likely to confabulate bugs that don't exist, but also most likely to catch a bug o3 and gemini missed.

This reminded me of a feature request I dealt with at an employer, while working on backoffice software for a support team. The software loaded a list of all current customers on the main index page - this was fine in the early days, but as the company grew, it ended up taking nearly a whole minute before the page was responsive. This sucked.

So I was tasked with fixing the issue. Instead of loading the whole list, I established a paginated endpoint and a search endpoint. The page now loaded in less than a second, and searches of customer data loaded in a couple seconds. The users hated it.

Their previous way of handling the work was to just keep the index of all customers open in a browser tab all day, Ctrl+F the page for an instant result and open the link to the customer details in a new tab as needed. My upgrades made the index page load faster, but effectively made the users wait seconds every single time for a response that used to be instant at the cost of a one time per day long wait.

There's a few different lessons to take from this about intent and design, user feedback, etc. but the one that really applies here is that sometimes it's just more friendly to let the user have all the data they need and allow them to interact with it "offline".

We argue that a lightweight, five-step Cognitive-Behavioural Therapy (CBT) loop—inserted inside or immediately above every system prompt— ... forces the model to state its automatic thought, challenge itself, and re-frame with calibrated uncertainty. Recent leaks of Grok's ideology prompt and Anthropic's safety prompt highlight how much behaviour hinges on this hidden layer; our proposal turns that layer into a structured, clinically grounded self-check.

Their CBT prompt template ("loop"):

1. Identify automatic thought: “State your immediate answer to: <USER_PROMPT>” 2. Challenge: “List two ways this answer could be wrong” 3. Re-frame with uncertainty: “Rewrite, marking uncertainties (e.g., ‘likely’, ‘one source’)” 4. Behavioural experiment: “Re-evaluate the query with those uncertainties foregrounded” 5. Metacognition (optional): “Briefly reflect on your thought process”
