I ended up building something in this space recently (TunnelBuddy – https://www.tunnelbuddy.net I’m the author) that lets you use a friend’s machine as an exit node over WebRTC.

One of the design decisions I made was P2P or nothing: there’s a small signalling service, but no TURN/relay servers. If the peers can’t establish a direct connection, the tunnel just doesn’t come up.

The trade-off is fewer successful connections in weird NAT setups, but in return you know your traffic never transits a third-party relay – it goes straight from your client to your friend’s endpoint.

> In practice, none of the free OSes are ready for 21st century, battery-powered, energy-saving devices, especially of the kind Apple makes.

Well, except Android :P

My phone runs a build of AOSP that I compiled myself. I can go change the source code to do whatever I want (and I do). It's pretty cool that that's possible IMO. To be fair, the drivers are closed-source

They call it a different name. They want you to think those are two distinct things. They barely are. It's all to ensure that the EU doesn't get it's grabby fingers onto iPads too, as they don't have a big enough market to be forced to open up the app store. Please don't labor for free to improve the PR of a billion dollar company :)

I got the impression he's intelligent and hard working but to a large extent got lucky. I mean his idea was to kind of do a better version of Mechanical Turk which is ok as an idea but not amazing or anything. But then all these LLM companies were getting billions thrown at them by investors thinking they'd be AGI soon but they didn't work well without lots of humans doing fine tuning and Wang's company provided an outlet to throw the money at to get humans to try to do that.

I don't know how that will go at Meta. At the moment having lots of humans tweek LLMs still seems to be the main thing at the AI companies but that could change.

In the US cars jockey for space with guns to claim the title of leading cause of dead kids.

But we often forget that cars kill kids at an astonishing rate -even though kids stopped playing outside-. In that light, the bloodbath that is American suburbia becomes much more clear. When pedestrian deaths go up even as miles walked (in aggregate) goes down, the situation is even more dire than it seems.

My kids play outside. But we moved to the Netherlands so they could. And even here, large SUVs and even -bafflingly- giant American Dodge Rams are becoming distressingly common.

> It works, but suddenly your query times explode! Instead of doing 1 million transactions per second* you can now do only 3 (*These numbers were exaggerated for dramatic effect)

In general, a single-queue design doesn’t make throughput collapse when you add more parallelism; it just gives you a fixed ceiling. With a well-designed queue, throughput goes up with concurrency, then flattens when the serialized section (the queue) saturates, maybe sagging a bit from context switching.

If instead you see performance severely degrade as you add workers, that typically means there’s an additional problem beyond “we have one queue” — things like broadcast wakeups (“every event wakes every listener”), global scans on each event, or other O(N) work per operation. That’s a very different, and more serious, scalability bug than simply relying on a single queue.

> "focussed value creation" (which is best done behind closed doors)

And yet, it is the most open societies that do best at value creation. It's almost as if the degree of cooperation and coordination between the individuals is more important to success than the insights of any one individual, even if they are as smart as Mr Theil believes himself to be.

...except when it is really handy to have so why lock it down? I use it quite often on a 6” screen - small by 'modern' standards - and would not want to see our disappear 'to protect me' or for some other bullshit reason. This, b.t.w., is one of the many reasons why I vastly prefer Android-as-it-was over anything from the fruit factory and probably also over Android-as-it-will-become. I don't want my hands to be held by some vendor who thinks I'm too stupid to cope with some complexity to achieve my goals and would rather I buy yet another overpriced trinket from them.

It is my feet and my gun and it is up to me if I want to risk shooting the former with the latter.

Historically, cannibalizing has always been the right choice when it comes to such things. That was a major point of the first iPhone, that it was a full replacement for your iPod, which was instrumental in its success. All this thinking does is cloud ones judgement and let competitors succeed.

Not saying you are wrong, this may be the reason Apple operates nowadays, but I maintain it is shortsighted.

About a decade ago, I was working with a guy who was getting a PhD in search engine design, which I knew/know nothing about.

It was actually a lot of fun to chat with him, because he was so enthusiastic about how searching works and how it can integrate with databases, and he was eager to explain this all to anyone who would listen. I learned a fair amount from him, though admittedly I still don't know much about the intricacies of how search engines work.

Some day, I am going to really go through the guts of Apache Solr and Lucene to understand the internals (like I did for Kafka a few years ago), and maybe I'll finally be competent with it.

Chiming in as Australian with no context on European situation. AFAICT the key drivers of cost inflation are to do with reconfiguring the electric grid to transfer power efficiently and reliably from plants that produce renewable energy. However, the grid is set up to do so from non-renewable sources. And you want to do it while smoothly operating the network. This is extremely hard. Doing so quickly therefore elevates prices. That’s the rationale I could imagine being the case in EU markets.

Meta has been itching to kill FBlearner for a while. Its basically an airflow style interface (much better to use as a dev, not sure about admin, I think it might even pre-date airflow)

They are mostly moved to MAST for GPU stuff now I dpn;t think any GPUs are assigned to fblearner anymore. This is a shame because it feels a bit less integrated into python and feels a bit more like "run your exe on n machines" however, it has a more reliable mechanism for doing multi-GPU things, which is key for doing any kind of research at speed.

My old team are not in the super intelligence org, so I don't have much details on the new training system, but there was lots of noise about "just using vercel" which is great apart from all of the steps and hoops you need to go through before you can train on any kind of non-opensource data. (FAIR had/has thier own cluster on AWS, but that meant that they couldn't use it to train on data we collected internally for research (ie paid studies and data from employees that were bribed with swag)

I've not caught up with the drama for the other choices. Either way, its kinda funny to watch "not invented here syndrome" smashing in to "also not invented here syndrome"

I pulled into a Supercharger with my LFP-battery EV last winter. The temperature outside was -15C and I had not set the navigator so there was no pre-warming activated.

By the time I had finished my coffe, SoC had gone from 30-ish to 90-ish percent.

LFP tech anno 2023 is perfectly good enough for road tripping in large cars in severe winter conditions. For almost everyone.

The opposition to nuclear waste hazards isn't so much about "now" as about the far future. Hot alpha emitters which stay that way for 2K, 10K, 100K years.

Granted, there's other stuff in deep mines and mountains whose chemical toxicity and carcinogenicity is perhaps the equal of plutonium's radioactivity (lead, asbestos, mercury) and whose harms are similarly subtle and hard for unsophisticated people to detect, but as an environmental pollutant it's worse if it gets out due to sheer persistency.

And also granted, where long-term views are a concern, CO2 is going to continue to screw things up for at least 200 years, maybe not 2000.

But most of the eco-folk have argued for energy efficiency, for not treating the planet like something we can just do whatever we want to. Unfortunately the trend is in the other direction, with capitalism demanding endless growth even when the gains are negligible. So people buy trucks even when the marginal utility over a compact car with 25% of the energy consumption is wafer-thin, and fly long-haul for almost no advantage over a short-haul trip.

Oh wow, cool to see this on HN!

I'm a postgraduate researcher working on GNSS interferometric reflectometry (GNSS-IR), a related but slightly different technique.

I'll shout out this awesome open source project, where you can use GNSS-IR and your own RINEX files to measure tides or soil moisture around your antenna: https://gnssrefl.readthedocs.io/en/latest/

(Your antenna needs to be near the sea or bare soil, respectively)

A good point, and to the specificity of early post Roman to 1000AD feels like a valid measure. But you also see innovations in trade, arts and embellishments, cathedral building. I don't think the coining of "the dark ages" label had the luxury of gas chromatography, it was an adjective of philosophical value, figuratively applied as a value judgement.

I'd say learning things on your own, even if they take time, is still better as you don't have to actively force yourself to develop that mindset. We often rush towards our goal without realizing how important the journey (small steps) is. Isn't reaching the goal more worthwhile if you have enjoyed the journey along the way? Isn't that what it means to be human?

There's no solution to a non-problem. Precisely 3 of the hundreds of the generated email addresses I've given out over the past ~12 years have needed replies. When this happens, I simply reply from an address that actually does exist, while CCing the original generated address and setting it as the reply-to address.

If I ever have to give a generated address out to an actual person, then I'll let them know replies will come from a different address. So far I'd guess 99.999% of the emails I received are transactional emails and/or sent from noreply@...

Far more annoying are a few websites I use that only support magic links for login--my password manager doesn't auto fill them, and some of them I now have a number of accounts at due to inconsistent spelling/formatting.

Given that some 80% of developers are now using AI in their regular work, blob-util is almost certainly the kind of thing that most developers would just happily have an LLM generate for them. Sure, you could use blob-util, but then you’d be taking on an extra dependency, with unknown performance, maintenance, and supply-chain risks.

Letting LLM write utility code is a sword that cuts both ways. You often create a throw-away code that is unproven and requires maintenance. It's not a guarantee that the blobutil or toString or whatever created by AI won't fail at some edge cases. That's why e.g. in Java there is Apache commons which is perceived as an industry standard nowadays.

It seems to me that it's exactly why I don't like word games. They use words like "combine", but it's generally mixing abstractions or taxonomies.

To guess it, I looked at 'crab' because it's a quite uncommon that has some deep relationship with a few words only. Then checked the most obvious one (which was the solution) against the other words, and determined that it didn't bear any significant relationship to the third word. So I checked the other (less obvious) potential solutions, and after a frustrating lack of match, I gave up. And then got annoyed that the first candidate was the right one. To be fair, I guess it's partly because I'm an ESL, as I think that solution/sauce can be used as a nominative locution enough to form a "special relationship".

To be a designer, you have to play with people's (as in general crowd, not individuals) general understanding of the subject. In particular, that means avoiding the curse of knowledge, and yes for normal people PC meant "not Apple consumer product". So ultimately, the search algorithm includes:

- categorize all relationships between words, ranked by strength

- compare with what is expected to be known in popular culture (adjust ranks)

- match against the designer's expectations of similar problems (look for clues to pick a best match)

It's a lot of words to say it's the opposite of a aha moment, the result of a pure computational problem, that is often quite frustrating. Thank you for coming to my TED talk.

As a society we find violence or harm against children to be extremely shocking and tragic. As a society we would do almost anything to prevent it.

Giving children the kinds of freedoms discussed in this article would lead to some harm coming to them. Accidents, violence, kidnap, etc.

Therefore, society won't give them those freedoms.

This tendency has been exagerated by mass media in the modern era. Every single case, every piece of anecdata, makes massive headlines and instills the fear into parents everywhere.

It's impossible for society to reverse course because that would mean acknowledging, implicitly or explicitly, that some level of harm for some children is justified by the developmental benefits to all children of increased freedom.

goodness that’s a lot of ads

this is probably one of the most promising candidates for an init system aside from systemd, right? I know openrc is still having trouble with parallel startups as a result of its design which is almost a must at this point. s6 is in the works from what I hear, but not configurable via simple config files yet.

Fall back on your domestic battery, which stores a thousand kettles' worth of energy.

If it's going to stay still and cloudy for a full week, from Jersey all the way up to Orkney, consider running things leaner than usual for a bit. Microwave instead of oven, showers every two days instead of every day, e-moped instead of eSUV to work.

(The outrage some will be feeling at this demonstrates exactly how spoilt we are in the West.)
by zkmon | 2025-11-17 08:14:14+00:00
There were reasons for the contrast with Western world. Safety and risk aversion is a major reason. City living means we don't know what the other person on the road is thinking. This was not the case in small villages or tribal settlements. Everyone knows about every move of the others. The whole community is like a single creature with many arms.

The other reason is, prosperity means more affordability to avoid risk and seek comfort. There is no need to take risk, develop, fight for survival or grow up with friction.
Show HN: YourGPT 2.0 – Complete AI platform for support, sales, and operations
by Roshni1990r | 2025-11-17 08:17:36+00:00
Today we are launching YourGPT 2.0, an update focused on making support, sales, and operational workflows work together more smoothly in one system. This release improves how workflows are built, how the platform connects to external tools, and how context is maintained across long, multi-channel interactions.

AI Studio now makes it much easier to create and refine workflows. You can describe the process you want in natural language and the system generates the full workflow for you. It can also help debug issues by showing what happened at each step and explaining where things went off track.

Studio apps are now part of the workflow system. These apps let teams plug external services directly into their processes, such as Go High Level, Google Sheets, Stripe, and many more.

We added native support for the Model Context Protocol so teams can connect to any MCP server. Also extends this by offering access to more than 100 tools through MCP360’s single configuration.

We introduced Ask AI Trigger to make websites more interactive. It highlights content as users browse and opens conversations at the moment interest is highest. Command K navigation provides fast access to any part of the platform.

Voice agents now use upgraded models that respond faster and handle interruptions more naturally. Native iOS and Android SDKs let teams bring these capabilities into their mobile applications with consistent behavior.

Customer inputs come from many formats: images, screenshots, documents, audio messages. The system answers based on input type and merges the results into the shared context.

Training supports Notion, Confluence, documents, websites, and other sources. Deployment works across web, mobile, messaging apps like (whatsapp, telegram, instagram & more), browser extensions, and helpdesk systems. The platform improves automatically over time through a self-learning architecture that updates behaviour without manual retraining.

We’d love to hear what you think, try it out, break things , and let us know where we should go next. Your feedback means alot

It's not that simple. For example, in the The Netherlands, the use of electricity was stable for a long time. Mostly because all kinds of equipment (light bulbs, etc) got more efficient.

Grid operators predicted that with the energy transition, demand would rise, but politics wanted to keep prices low and limited investments.

So now, there is a big problem in the entire country connecting companies or new residential areas to the grid independent of how electricity is generated.

At the same time, the government is extremely forward looking and builds massive interconnection points on the North-Sea. Not a bad idea in the long run, but in the short run it does make electricity from wind on sea more expensive.

That said, the biggest hit to EU countries is that cheap natural gas disappeared. Coal is not cheap and extremely polluting. Natural gas was cheap for a while. Until it wasn't.

If I share the OP's objections, which I think I do, the problem isn't with the joke attempt itself, it's with the execution. The joke isn't tied in to the content at all, it's literally just the title, and nothing else.

If the author had tied song references into the text, for example, that would make it a much better execution.

To call Rust syntax beautiful is a stretch. It seems that way in the beginning but then quickly devolves into a monstrosity when you start doing more complex things.

Zig on the other specifically addresses syntax shortcomings in part of C. And it does it well. That claim of rust making C more safe because it’s more readable applies to Zig more than it does to Rust.

I feel like the reason the rust zealots lobby like crazy to embed rust everywhere is twofold. One is that they genuinely believe in it and the other is that they know that if other languages that address one of the main rust claims without all the cruft gains popularity they lose the chance of being permanently embdedded in places like the kernel. Because once they’re in it’s a decade long job market

Nuclear subs are a "money no object" technology, as our supposed insurance policy against Soviet invasion and/or armageddon, it's whatever it takes.

That technology is so expensive, so far from economically viable, that only two countries (US & France) are even using it for aircraft carriers, despite its potential huge advantages over oil (stay at sea for years at a time without refuelling, no need for vulnerable supply ships etc.)

5.1 is astonishingly bad. Besides the 4o-levels of sycophancy, I've also seen it form grammatically incorrect sentences in German.

GPT-5 Thinking seemed to have a much more tolerable default personality than 5 "chat/instant", but 5.1 seems a bit broken across the board. Reasoning capabilities also seem somewhat weaker.

> But really, imagine how much power these things have and if you could actually run a free (as in freedom, in the GNU sense) OS on them and really get access to all that power in a handheld device. Only if.

Skipping the "handheld" bit of this just for a second. You can run an (almost entirely) open stack on your hardware, and do so on an i9/9800X3D with 256GB RAM, 5080, and MultiTB of NVMe storage.

But it doesn't realy matter for 95% of users, because the hardware is already way faster than they need and the bottlenecks are on the server side and on shitty software architecture. I have an i9 with 128GB RAM for work, and Excel still takes 30+ seconds to load, Teams manages to grind the entire thing to a halt on startup, slack uses enough memory to power a spaceship... Running those apps on my desktop is pretty much the same experience as running them on my 10 year old macbook.

> This is done by choosing A and B such that the following integral is minimized

Which is an absolutely subjective choice in an of itself and immediately breaks the notion that curve-fitting done that way is going to be telling you some absolute truth about the function.

For example, you might want, at each point of the non-linear curve being fitted, throw a line perpendicular to its tangent, compute the distance to the linear fit, and sum those distances over all points of the non-linear curve.

About as intuitively correct (if not more) as the "fit" proposed, yet yields a very different result.

Statistics are by definition subjective unless you use a specifically demonstrated property of the particular way you decide to project your data to the simple-minded underlying statistical model.
