I've tried to lightly allude to Mastodon here:

>Social aggregation features like notifications, feeds, and search are non-negotiable in modern social products.

Conceptually, Mastodon is a bunch of copies of the same webapp emailing each other. There is no realtime global aggregation across the network so it can only offer a fragmented user experience. While some people might like it, it can't directly compete with closed social products because it doesn't have a full view of the network like they do.

The goal of atproto is enable real competition with closed social products for a broader set of products (e.g. Tangled is like GitHub on atproto, Leaflet is like Medium on atproto, and so on). Because it enables global aggregation, every atproto app has a consistent state of the world. There's no notion of "being on a different instance" and only seeing half the replies, or half the like counts, or other fragmentation artifacts as you have in Mastodon.

I don't think they're really comparable in scope, ambition, or performance characteristics.

>Also what I hear about Baldur's Gate 3, but I haven't played.

They're very different, so they're difficult to compare. BG3 is very much a tabletop RPG in electronic form, with a focus on tactics and positioning. I guess you could call it fantasy XCOM. In terms of player choices, BG3 is more open, though I'd say it's almost to its detriment, because it's jankier than DX. You'll probably get at least one bugged out quest during a playthrough. Nothing game-breaking, but still. It kind of kills the immersion.

not really. this may be true for the average player, but as Magnus has explained multiple times, all he or another top GM would need to be near-unbeatable would be to check an engine in 1 or 2 critical positions per game. this essentially impossible to detect statistically. even if a cheater were to use an engine on every move, it would be trivial to just vary the engine used for each turn, vary the number of moves picked, sometimes play a slightly worse move to evade detection, etc etc

Yeah but the point is you want to look down the street and see if there's a city bus a few blocks away or not. If so, hurry up and walk the block to the bus stop. If not, quickly grab a coffee or decide to grab a Citibike or whatever else that depends on that information.

Spotting buses a few blocks away is a crucial skill in cities.

> 3. We rely too heavily on the ability to patch after the fact...

I agree on all points and to build up on the last: making a 2.0 or a complete software rewrite is known to be even more hazardous. There are no quarantees the new version is better in any regards. Which makes the expertise to reflect more of other highly complex systems, like medical care.

Which is why we need to understand the patient, develop soft skills, empathy, Agile manifesto and ... the list could go on. Not an easy task when you include you are more likely going to also fight shiny object syndrome of yours execs and all the constant hype surrounding all tech.

Mostly, it's SpaceX detailing how increases in launch count and scale are necessitating infrastructural, operational and organizational changes at launch sites.

Oh how the times have changed. We went from waiting months from one Falcon 9 landing test to another and to the point where people are having to rethink how to run spaceports to be able to sustain SpaceX's insane "2.5 launches a week" cadence.

running a domain costs money. there's no way around that - it requires server resources to respond to dns queries, and that requires servers and electricity.

so to offer it for free means somebody has to subsidize it. letsencrypt can operate because big companies with lots of money want their ads to be delivered without being intercepted by an ISP. what's the motivation for anybody to subsidize free domains?

I’ve been increasingly addicted to Mentour Pilot videos in the past month, and I couldn’t agree more with you. Modern (and by this I mean really 1990s+) pilot training, with its decision frameworks and CRM ideas, is a model for how most professionals ought to organize their work and deal with challenges. Of course it’s easy to see why aviation developed such rigorous systems, but we’d do well to steal as many of their ideas as we can. If anyone isn’t already really familiar with those two concepts especially, I bet it would be worth your time to look into them a bit.

Sadly, it's hard to imagine a world where something like this will ever catch on. The target audience for "traditional" social media is very different from the niche of people who want decentralized social media. Most people just use social media as a means to an end and don't really care about the systems behind it.

If the answer is that most people should just make a bluesky account, that defeats the whole purpose because then everyone will still be on one or two large providers.

By checkpointing once the agent loop has decided it's ready to hand off a solution, generating a structured summary of all the prior elements in the context, writing that to a file, and then marking all those prior context elements as dead so they don't occupy context window space.

Look carefully at a context window after solving a large problem, and I think in most cases you'll see even the 90th percentile token --- to say nothing of the median --- isn't valuable.

However large we're allowing frontier model context windows to get, we've got integer multiple more semantic space to allocate if we're even just a little bit smart about managing that resource. And again, this is assuming you don't recurse or divide the problem into multiple context windows.

But since we don't know where those false negatives are, we want radiologists.

I remember a funny question that my non-technical colleagues asked me during the presentation of some ML predictions. They asked me, “How wrong is this prediction?” And I replied that if I knew, I would have made the prediction correct. Errors are estimated on a test data set, either overall or broken down by groups.

The technological advances have supported medical professionals so far, but not substituted them: they have allowed medical professionals to do more and better.

When the Trump administration came close to forcing a divestment/shutdown on TikTok in 2020, Americans were 10% of TikTok's user base but 50% of revenue.

Of the top 50 most-followed accounts <https://en.wikipedia.org/wiki/List_of_most-followed_TikTok_a...>, 21 of 49 (not including TikTok itself) are American.

> Due to automated ECG interpretation built into every machine

Oof - I hope the tools you're using as a physician are better than in the field as a paramedic.

I have never met a Lifepak (or Zoll) that doesn't interpret anything but the most textbook sinus rhythm in pristine conditions as "ABNORMAL ECG - EVALUATION NEEDED".

One of the issues that AC Transit (SF East Bay bus agency) has is that it purchased a lot of Hydrogen Fuel Cell busses which have issues which dramatically impact their reliability. It's also very expensive technology. There's a decent argument that public agencies _should_ invest in early emerging technologies like that but the costs should not be borne by the transit agency alone, at the cost of poor service for its riders.

> bigger warning signal for me is when I see people in public talking about stocks

Which is interesting "this time" because much of the issue may be due to historical and tax-quirk fullfilling index weighting. And the people invested nearly entirely in these indexes is kinda by definition the people who normally don't even look at their investments. "Irrational autopilot"?

Opencode, been there, it has a Cerebras/qwen-coder out of the box preset! Unfortunately I found the TUI somewhat clunky, I dislike text windows and the terminal scrolling was not available, it was enclosed into the current viewport. One of the features of working in a CLI is that it's scrollable - maybe there's a setting for that?

Also it had some cutoffs with Cerebras - every once in a while it will get a reply then nothing happens, just stops there. I think 4xx errors weren't handled well either. Same happens with Codex with a Cerebras provider. Unfortunately there isn't a compelling reason for me to debug that, although I like that Codex is now Rust and OSS, much more fun than decompiling Claude for sure.

That said, I liked that it has sessions, undo and Plan x Code modes ("build" I think it was called), although that's already a non-pattern for most coding agents, it allows me to have say a OpenAI API o3 or gpt-5 to do some paid planning. But even that is not needed with something like Cerebras that just shoots code out of its butt like there's no tomorrow. Just rinse and repeat until it gets it right.

EDIT: just recalled another thing about opencode that messed me up: no exiting on ctrl-d blows up my mental unix cognition.

I'm a simple man, I see a Dan post and I click.

I'm a bit concerned that the open web only won because of first mover advantage. What gives me hope is OSS winning.

I'd love to see something like atproto win though. It's clear that a major issue with social media is network effects preventing better apps from becoming popular.

I think the context some may be missing here is that Blue Origin and ULA have been attempting to get the FAA to limit SpaceX's planned Starship operations in Florida on the basis that they will have too much environmental impact and impede theirs:

https://arstechnica.com/space/2024/07/theres-not-enough-room...

So this is basically SpaceX arguing back about how these concerns aren't valid or can be mitigated through more informed safety margins and co-operation between launch providers.

Starting at around thousand bucks, with a subscription for their pods, requiring constant maintenance, with a huge footprint - I'd say this is targeted for someone with more money than sense. There aren't any clear numbers of what this device can do. The negative effects of CO2 are also quite overstated, and I say this as someone with two CO2 monitors in their home.

LLMs are deterministic*. They are unpredictable or maybe chaotic.

If you say "What's the capital of France?" is might answer "Paris". But if you say "What is the capital of france" it might say "Prague".

The fact that it gives a certain answer for some input doesn't guarantee it will behave the same for an input with some irrelevant (from ja human perspective) difference.

This makes them challenging to train and validate robustly because it's hard to predict all the ways they break. It's a training & validation data issue though, as opposed to some idea of just random behavior that people tend to ascribe to AI.

* I know various implementation details and nonzero temperature generally make their output nondeterministic, but that doesn't change my central point, nor is it what people are thinking of when they say LLMs are nondeterministic. Importantly, you could make llm output deterministically reproducible and it wouldn't change the robustness issue that people are usually confusing with non determinism.

The bit about aggregation is interesting, but it's not clear to me what the performance characteristics will be for very popular accounts. Presumably Justin Beiber's repo cannot be expected to handle 100 million WebSocket connections, all of which push out a message the instant he posts something. Is it vital to have more centralized hosts which can implement the sort of hybrid push vs. pull models that Twitter famously needed to implement?

The problem with rail isn't just labor, it's land acquisition. For the old freight lines that was done centuries ago, now that virtually all land has been claimed by someone it's much more expensive by default. On top of that, California got Musk disrupting everything with Hyperloop.

You need to use eminent domain on straight lines as much as possible for HSR, both to keep costs low and to allow for actually high speeds, but that's risky for legal challenges and even then, horribly expensive at US scales.

Yes, China has larger scales and still gets it done, but they a) just throw money at the problem and b) just do what the CCP wants.

> Have crazy people screaming on the street corner in the city and people will retreat to the suburbs and order from Amazon instead of going shopping, order a private taxi for their burrito instead of going to a restaurant.

That's not made easier by the fact that many cities just hand one way bus tickets to local homeless and nutjobs that bus them off to somewhere else [1], often to Democrat-run cities. In addition to that, there are almost no asylums left to take care of the nutjobs because a lot of them had been forced to shut down for sometimes atrocious violations of human rights many decades ago. Some areas now (ab)use jails and prisons to punish homeless people for being homeless, a practice that has also come under fire for creating the same abusive conditions, on top of scandals like "Kids for cash" [2].

The obvious solution to a lot of the problems with nutjobs, homeless and drug addicts would be a sensible drug policy combined with a "housing first" policy. Both of that has been tried in the US and in other countries worldwide to a sometimes massively positive effect, the problem is it has to be done federally - otherwise you end up like Frankfurt here in Germany, where Frankfurt pays the bill for drug addiction treatments and somewhat safe consumption facilities, but ended up having to pay that for people from almost across the whole of Europe.

> If the public sector were efficient, responsive and pleasant people would be voting for more of it.

It could be at least pleasant and responsive, the problem is you need (a lot) of money to pay for it, and no one likes paying taxes. It's a chicken and egg problem across Western countries - ever since up to the 80s, when neoliberal politics, trickle-down and lean-state ideology took over, public service has been cut and cut and cut. People don't believe any more that paying higher taxes would yield a net benefit because they lost all trust in politicians, and I don't see any way of fixing that - not without a stint of a good-willing dictator at least, and I don't see that on the horizon at all.

This is not an update for SpaceX fans. It's aimed squarely at people who have opposed SpaceX's expansion in Florida at Kennedy Space Center and Cape Canaveral. These people have made arguments about safety and the environment as well as disruption to the operations of SpaceX competitors. Some of these arguments may be made in good faith but some are simply aimed at obstructing a competitor or political opponent. SpaceX is countering those arguments here.

> As a field, we already know how to do security.

Well, AI is part of the field now, so... no, we don't anymore.

There's nothing "careless" about AI. The fact that there's no foolproof way to distinguish instruction tokens from data tokens is not careless, it's a fundamental epistemological constraint that human communication suffers from as well.

Saying that "software engineers figured out these things decades ago" is deep hubris based on false assumptions.

I quit 5 years ago and my memory works much better.

I firmly believe that every bad hangover permanently damages memory ability. My job, most education, my enjoyment of personal conversation, all work better with good memory.

If I could go back and do it again I’d never drink to excess (even a single time in my life). For me that would probably mean not drinking at all or never drinking in a situation where I’d ever have more than one.

> I’d also add that there’s a powerful benefit to having something like Medicare as a right of citizenship

While not attached to citizenship, there already is something built in. New immigrants to the US often have to have a financial sponsor (I did, on my K-1 fiance visa). That sponsor has to agree (and demonstrate ability) that in the event that the new immigrant claims public benefits in the first ten years of their residence in the US (Medicare, Social Security, etc.) that the government is entitled to recoup those benefit costs from the sponsor.

>I don't think it's a good idea for the US government to dictate (or attempt to dictate) specific deals and specific terms for those deals.

The US government is mandating the transaction happening in the first place, so of course there is going to be government input into the terms. Look at the forced sale of Bayer's US division during WW1. Or, the government requiring very specific actions by GM in return for the 2009 bailout.

>It looks like this massively undervalues TikTok's US operations

Valuation is an art, not a science.

It's a sale required by law, so it's not surprising that the terms are lower than what may be achievable through a public auction. Also, the details of the transaction matter; much of TikTok's value is in the algorithm, and how and whether that is transferred is unclear. But I'm not going to complain about American buyers paying less than they might otherwise.

> A human can effectively discard or disregard prior information as the narrow window of focus moves to a new task, LLMs seem incredibly bad at this.

This is how I designed my LLM chat app (https://github.com/gitsense/chat). I think agents have their place, but I really think if you want to solve complex problems without needlessly burning tokens, you will need a human in the loop to curate the context. I will get to it, but I believe in the same way that we developed different flows for working with Git, we will have different 'Chat Flows' for working with LLMs.

I have an interactive demo at https://chat.gitsense.com which shows how you can narrow the focus of the context for the LLM. Click "Start GitSense Chat Demos" then "Context Engineering & Management" to go through the 30 second demo.

There are some github project which offer free domains if you send them a issue asking them kindly for subdomain iirc

https://github.com/topics/free-domains

Another thing, the thing that you mention is really similar to how tor onion links work... Except they offer encryption and prevents MITM/any other ways while still having your ip hidden.

Another idea which I use sometimes is to use something like cloudflare tunnels or ssh forwarding with things like serveo.net or any ssh based remote forwarding in general like pinggy or even ngrok.

If you are using this in some internal thing, I can also suggest something like piping server which I really like and I want to build something like a web browser tor-onion links esque but on top of piping server, its really really cool

in chess lingo, most common is "moves"; only in a weird circumstance (beginners?) would you need to say "legal".

the "possible" qualifier would probably be used for an "english" reason rather than a "chess" reason, to suggest "future" moves as opposed to the moves already made to get to a position. it would be more likely for whatever reason to say "how many possible moves" than "how many future/hypothetical moves", i.e. the use of possible is not to rule out the idea of impossible, simply to mean how many "could you make now from a particular position" and/or i guess to suggest "possible initial moves" as opposed to future follow-on moves.

the ambiguity is not really in chess, it's in english (and probably every other language also)

I feel very conflicted about this work.

On one side I find these ideas extremely compelling. This is aligned with the Indie web body of work, that pictures anyone having a personal website of their own content and ownership over that. And this page an article are beautifully put together.

On the other hand, we haven’t really seen a lot of developers adopting these standards for their own projects (like using this for their personal website or open source project). Nor from casual users (including people who make their own blogs and websites).

I am deeply concerned about the apathy people have towards the idea of ownership, openness and interoperability. It gives the idea that people just want to be fed TikTok and Instagram reels.

I respect the vision and the work. Will personally see if we can use this for our work. But I wonder how we make this into something that’s not just a micro niche hobby.

> it's not a question of "offloading" it, it's a question of reaping the benefits of global competition

_What benefits_?

> Would you really be better off if you could only buy cars made by US manufacturers? Did americans really lose out when Toyota and co arrived?

Been through Flint, MI lately?

How about Gary, IN? Camden, NJ? East St. Louis, IL?

> Would Boeing aircraft really be better if they didn't have to compete with Airbus? Or would the incumbents just get lazy?

They already do have to compete with Airbus for pretty much everything that doesn't involve the US Government as a customer. That's the majority of the global aircraft market. How's that working out? The incumbent still got "lazy", not so much from entitlement but from a "need" to constantly reduce costs while simultaneously increasing revenues for the benefit of shareholders. You can only make aircraft building (or anything else) so profitable before you hit a ceiling. Boeing hit that ceiling, but of course, that doesn't matter. Number must go up.

People in postindustrial economies cannot work as cheaply as people in developing economies because they must pay local prices for goods and services required for them to live. Going with the global competition because "it's cheaper" doesn't address the hundreds of thousands of people in the US who now don't have the ability to earn a living in the way that they did before while still being forced to consume using the value of their labor. Worse yet, it enriches people who don't have our national best interests in mind.

This kind of "globalization benefits Americans" mindset is why we're in the mess we're in now with a tyrant in office and people having no faith in the economy or the future. It's not 1990 anymore. The experiment's over, it failed. Horribly.
