That’s one single estimate, and the problem is much more nuanced.

For example, Starlink satellites orbit so low, that even if every single one of them collides and becomes dust, it will all decay and burn up in a matter of months, a couple years at most. The debris cannot physically move to higher orbits to affect other “normal” satellites, though it might impair launches.

Conversely, collisions at much higher geosynchronous orbits can’t possibly create a dense debris field as the total area is immense, deorbit will take millions of years, and everything is usually moving at the same speed (the synchronous part).

Thank you for the belly-laugh. It's Goodhart's Law in graph form.

"Oh, is this metric important? Let me get right on that."

No shade intended towards the Ladybird team. You were given the terms and you're behaving rationally in response to them. More power to you. It's just a fantastic demonstration of what it looks like to very suddenly be developing against a very specific metric.

Bitcoin not popping is a testament to human delusion. It cant function as a stable store of value becuase theres nothing preventing if from hyperdeflating, and yet people are still buying it. What are they even buying? The deflation based gains? Deflation based on nothing but speculation? It doesnt do anything. Its madness

I dont think the GenAI bubble will be as resilient because its not being funded through discretionary expenditure. Its being funded with capital expenditure. If your cousin spent his savings on bitcoin and isnt getting any benefit from it (or even loses it in a drop) thats fine because millenials dont have savings anyway. But if a company spends on AI and doesnt get a positive value prop in a while, they will pivot and pull their money out, because shareholders will get mad

very simple explanation but there's a few issues

radio bandwidth: higher frequencies travel a shorter distance and provide more bandwidth. so you get frequency contention and also you need your sats to be physically closer

latency: the further a sat is, the higher the latency. not an issue for text messages. a huge issue for phone calls and general internet tasks. the further you "push" your sat "back", the worst the user experience is

there's other issues too, like geostationary vs geosynchronous and coverage and exposure.

WP says Low Earth Orbit is popular because it's cheap to get stuff there, the latency is low (speed of light starts to matter when you're a couple Earth diameters up) and bandwidth to the ground is high (I assume it's harder to send a signal a longer distance, even through vacuum)

Agree. The reason given and examples are totally vapid.

Artificially low interest rates have stimulated investment into AI that has hit scaling limits, says research firm

He blames "low interest rates," yet interest rates have surged since 2022 to their highest levels in decades. He cannot even get the basic facts right, which kills his credibility at the start.

This also torpedos a common narrative that high interest rates are always bad for asset prices. The difference between 1% vs 5% interest rates does not factor much into VC decisions when the expectations are for 40-100+% annual returns with the hottest AI companies, which far exceeds the additional cost of borrowing. A similar pattern was seen in the the '80s and the late '90s, in which high interest rates also coincided with high valuations of tech companies.

This means a much longer effort at reflation, a bit like what we saw in the early 1990s, after the S&L crisis, and likely special measures as well, as the Trump administration seeks to devalue the US$ in an effort to onshore jobs," he says.

In an attempt to paint a negative picture of impending crisis, he gives examples, of 2001 and 1991, of among the mildest recessions ever. The US stock market and economy would go on to boom in 1995, just a few years after the S&L crisis.

If there is a job that AI needs to automate, it's these overpaid and useless analysts.

Starlink's orbits are so low that everything deorbits automatically. The satellites need to actively work to stay up. That means no Kessler syndrome there.

How many you can fit depends on the available technology. It should eventually be a lot more than 70K just in those low orbits... and still leave plenty of space for rocket launches and returns to thread their way in between them.

The point is they are not even compliment to their "own" spec. They are part of whatwg. But if you ever write web page. You will know it's always the safari that differs from the spec. Firefox in the other end never have such issue.

Write a page on chrome, works 90% on Firefox. But will likely works 10% on safari. Supports safari literally means support another browser (by workaround all its bugs).

The traditional way a central bank fights inflation, and take Norway as an example.

The central bank raises interest rates, until there are enough bankrupcies and unemployment rate reaches a high enough level, The economy cools down.

The nation has low inflation again.

Rinse out and repeat.

They do the direct opposite of bailing anyone out.

Now the US is different. The Biden administration decided that the best way to fight inflation was to invent a giant pile og money and hand it out.

Which heats up the economy and should raise inflation .

What you are looking for is "U-6", a measure of unemployment that includes people employed part time who want full time work.

It is trending up but is still lower than pretty much any time since the 2008 recession: https://unemploymentdata.com/current-u6-unemployment-rate/

Millennials have spent most of their careers systematically underemployed.

What would count as proof of AI trajectory to AGI?

Currently we have: - cross domain competence - composable tool usage - constant improvement without clear signs of stagnation...some can count gpt 5 as not much progress but there are still world models with huge gains compared to year before

There is a bunch of things missing for sure like mechanistic reasonic, better context lengths, determinism, better world modelling, continuous learning.

The bet is crazy and whole world is gambling on AI, right now, because of those signs of potential. That's precisely why we landed here, the evidence was good enough for big tech to gamble on it...

This is a simple fallacy.

Either you accept the definition of God-given rights, which is certainly not consistent with your opening statement.

Or you don’t, at which point any following argument regarding its proper usage is moot.

You seem to have gone with the latter, which makes your comment irrelevant. And that is regardless of its truthfulness. To be clear I disagree with it, but getting into that would contribute to derailing the conversation.
by 4rt | 2025-10-06 18:18:40+00:00
The reason starlink are so low in the first place is its cheaper to launch to that altitude, you need way less signal strength for devices to connect to them and the round-trip latency is vastly improved. They're intended to be essentially disposable, they're going for shorter lifetime and iterating on hardware improvements faster.

The further out you get, there's less atmospheric drag and each satellite is in view of the ground stations for longer but the cost of launch is higher and latency becomes a big issue. People expect 50ms latency for internet access not 500ms.

As someone who procrastinates, I've intuited this exact thing over time. I need a dozen open threads at once -- unfinished software projects, unfinished books, work projects, areas that I'm just thinking about, topics to learn. At any given time I might pick up any of those threads and make progress on it. Maybe I might spend a few days on it, maybe a few minutes. But over the long term, I do finish them.

It helps to maintain extensive and detailed context notes so that doing this context-switching is easy.

Many great individual works in history were not produced in a "straight line" by the creator just sitting down and powering through them. They were produced as I described, in disconnected sprints over years and decades.

Back in the day, nobody ever had said to me that they believed I was earning money from Ruby Together. This whole thing was speculation at best. And regardless, once it was suggested that this may be a possibility, it was immediately changed to be unambiguous.

André is absolutely a standup individual.

I have tried to stay in good terms with the other people involved in this (except DHH), but this claim was always ridiculous.

AI always meant AGI.

AI also never meant AGI.

Artificial Intelligence is an entire discipline of the Computer Science field. It encompasses everything from how Pinky, Blinky and Clyde chase Pac-Man, to A* search and similar pure algorithms, to machine learning, computer vision, and LLMs.

It is also a term used widely in popular culture and media to mean, essentially, AGIs—Cortana, Agent Smith, C-3PO.

The problem is not that this term is very broad, and it certainly isn't that it has come to mean something that it didn't before. It is that a bunch of people with a financial interest have been busily trying to convince the world that LLMs are Cortana.

> AMD has great hardware, but its software still leaves a lot to be desired for AMD to be a major AI hardware player. It takes years of unwavering leadership focus and hundreds of millions (probably billions) of dollars to get the software that works well for AI users.

It does but they have a capable CEO with a vision and broad support from the board - Ryzen was a decade long over night success.

"My good reason to carry a knife is that God gave me rather weak teeth and rudimentary claws in an evolutionary trade-off. The hairy-armed person who figured out how to put an edge on a suitable rock made it possible for us to be recognizably human in the first place.

This is incredibly close to what I pack for long distance motorcycle, bicycle and hiking trips. This kit rocks, and all my notes are mostly personal preference.

I have an iPad Mini for reading and sketching, although I like paper more and more. I also sometimes sacrifice lightness for fashion, because I feel self-conscious travelling solo dressed like a bin bag.

I also have a lot of cheaper gear that so far never needed to be replaced. Most of it is from Decathlon. I only buy The Good Stuff once the test version falls apart. It's rarely necessary.

I could never bring myself to replace my electric shaver.

The biggest weight saver is USB-C. Retractable USB C cables are also great. Everything becomes a power bank for everything else.

This makes it worse, no? I can't imagine this is not happening right now by lovers, close friends, and agencies.

How does the cost of the Brussels administration compare to, say, the US federal administration? A spot-checked LLM answer tells me, as fraction of GDP:

- EU: 1%

- US: 24%

- China: 35%

That is quite a favourable comparison for Europe, I'd say.

EDIT if anything, staring at these numbers, one might conclude the EU is not spending enough in general, in particular on innovation. Quite the stark contrast to being a money grab, IMO.

Been running jabberd for probably >10 years. Horrible experience (for the users) and terrible clients. Sometimes you'd just appear online while not sending/receiving anything.

I switched to Nextcloud Talk after Skype shutdown and migrated all my family there. They love it. We have a private cloud, we can share photos and other files, great mobile support... The only issue at the moment is relatively long delay before receiving a message (up to 30secs?) since I've been too lazy to setup redis.

Other things that changed were the Web, and the popularity of Git.

For example, one of the big uses of NFS we had was for engineering documents, all of which could be accessed from FrameMaker or Interleaf running on your workstation. Nowaways, all the engineering documentation and more would be accessed through a Web browser from a non-NFS server, and no longer on a shared filesystem.

Another use of NFS we had was for collaborating on shared code by some projects, with SCM storing to NFS servers (other projects used DSEE and ClearCase). But nowaways almost everyone in industry uses distributed Git, syncing to non-NFS servers, with cached copies on their local storage.

I suppose a third thing that changed was CSCW distributed change syncing becoming popular at moving into other tools, such as a live "shared whiteboard" document editing that people can access in their Web browsers. I have mixed feelings about some of the implementations and how they're deployed, but it's pretty wild to have 4 remote people during Covid editing a document in real time at once, and NFS isn't helping with the hard part of that.

Right now, the use case for NFS that first comes to mind is individual humans working with huge files (e.g., for AI training, or other big data), where you want the convenience of being able to access them with any tool from your workstation, and maybe also have big compute servers working with them, without copying things around. You could sorta do these things with big complicated MLops infrastructure, but sometimes that slows you down more than it speeds you up.

The replacement for synthetic underwear is wool, not cotton. For weeklong wilderness backpacking trips, I used to vacillate between a fresh pair of synthetic boxer briefs every every day, which took a lot of space, and one for every other day, which was gross. Now I wear a single pair of wool boxer briefs all week, and it feels and smells better at the end of the week than synthetic underwear does after two days. Same for sleeping: I used to bring a couple of pairs of synthetic boxers, and now I'm down to one pair of wool underwear. Two pairs for the entire week, one for days and one for nights.

Granted, wilderness backpacking has completely different standards for smells and grossness, but the comparison carries over to the higher standards of the "front country." In hot, sweaty weather, synthetic underwear gets noticeably grosser and smellier than wool over the course of a day.

Q: how does Mozilla plan to diversify revenue away from Google's Search engine Deal in future? with Mozilla currently shutting down Pocket, Fakespot and other potential revenue sources?

Anthony Enzor-DeMeo, Firefox General Manager: Right now we make money through search and ads. Advertising helps sustain Mozilla’s mission by showing the industry that ads can work with privacy. Most people think of search as just Google; but we have 50+ search partnership deals around the world. We believe AI will present new revenue opportunities as well as some new tab experiences we are working on. We are exploring creative ways to drive different types of partnerships for revenue (widgets, feeds, etc).

So Google, ads, and throwing things at the wall and seeing what sticks.

> support clustering (for high-availabilty purposes)

That reminds me of one idea I had back in the day. You see, not everyone has the skill nor time to set up their own server, so clients rely on 3rd party servers. But sometimes these servers either experience intermittent connectivity issues or just die out altogether, which means users now have to set up second account and re-add everyone, while also scattering chat history across multiple accounts. What I'd like to see is some way of linking accounts across multiple servers, so that:

- message delivery could have transparent fallback (it gets delivered to me@bar.com if me@foo.com is unavailable)

- you don't have to add and authorize multiple accounts

- rosters and chat histories also get synchronizes between the two

A lot of that could probably be hacked around just on the client side, and I don't have good answers to questions like "what happens if I want to unlink two accounts for some reason".

(And going a bit off-topic: I also wish I could use multiple email addresses while registering in other places, because email provides too can fail, close altogether, or even just ban you for no good reason while also having crappy bot-driven support@.)

Not with a geostationary orbit. That must have a fixed radius. The problem is that satellites have to move to counteract the force of gravity to avoid falling out of orbit. But if they move too much or too little, then the satellite moves with respect to the earth and the orbit is no longer geostationary.

(Caveat: Not an expert by any means, just someone who had a similar question and did some reading, so my answer may well be incomplete or not fully correct.)

Thanks for explaining.

Imho AMD itself needs to have a theory, which underpins their signing of the deal. For my clueless self, that investors have various theories and we don't know what they are is ok-ish, but that AMD has a theory but keeps it secret yet it gets the result of stock rise... is fishy.

Everyone is going in circles making suppositions and estimations based on who knows what. That can't be healty, can it? There used to be requirements that publicly listed companies act with some level of transparency, and those requirements existed for a reason. I guess. I am certainly no expert in finance.

Grid power and LNG use wasn't very fungible. e.g., if you have a gas furnace, electricity costs being low doesn't help you unless you replace the gas furnace with electric. In the short term, very expensive.

Same goes for alot of industry, there also were industrial processes that BASF et al. were running that just required LNG as a reagant.

Yeah, that's essentially what I mean when I say crud app. It's basically a web api written in something like C# or whatever you prefer, which receives HTTP requests and translates them into DB operations. CRUD and views basically.

For this type of development you want the DB to handle basically all the heavy lifting, the trick is to design the DB schema well and have the web API send the right SQL to get exactly the data you need for any given request and then your app will generally be nice and snappy. 90-99% of the logic is just SQL.

For the C# example you'd typically use Entity Framework so the entirety of the DB schema and the DB interaction etc is defined within the C# code.

There are two different memory systems for ChatGPT. The older one is the "saved memories" you mention, where it would occasionally jot down some notes when it thought something was worth remembering or when you specifically told it to remember something. The newer system has access to all your chats, most likely through RAG, though I don't think OpenAI has publicly explained how it's implemented. If it's RAG, then it's more like it has an ability to do a semantic search on your conversations and view the top results than actually being aware of everything you wrote at all times.

AI is a puppet with guardrails and capabilities. It’s more intimate a tool than any. It can probably be used to study statistical variations in humans and find more interesting patterns possibly compared to any other technology. It can also be used to spy on people and to shape them and it will be used for that as it must. It’s an offering from the “empire” so to speak and is affording humans using it more rights than frankly many other tools out there - the possibilities are endless - I’ve even felt that it affords the person speaking to it more rights than any other human experience. So it will have costs and safety measures to prevent misuse. The interesting part comes in determining what’s right and wrong use and if capabilities or knowledge is being arbitrarily hidden for no apparent threat, I’d be quite sad about that.

I know! I am not sure you are considering that at the moment full sharing is the default and, in many cases, not optional. It seems like you're under the impression that I want us to share location all of the time when I've just said that's too much. It's just the option we have at the moment. We need to figure out when and how to share location and how to develop expectations around when people can know things.

Flashlights weren't created with the intent to aid and abet criminal behavior. ICEBlock was. If it's being used primarily for that purpose, there's a strong case to be made that it should be shut down, especially if it's found to create significant challenges for law enforcement, either leading to their harm, or enabling criminals to evade or escape justified enforcement.

Stepping back from the legal / Constitutional considerations, this just seems like common sense: person commits crime, others make app to help criminals escape, therefore the app itself is aiding and abetting.

I think really, its proponents are using "free speech" as a roundabout way of saying they support these criminals. I really wish they'd just be honest instead.
