> Why on earth would we want a technology that’s as good at summarisation as it is at hallucinations to write encyclopaedia entries?? You can never trust it to be faithful with the sources.

Isn’t summarization precisely one of the biggest values people are getting from AI models?

What prevents one from mitigating hallucination problems with editors as I mentioned? Are there not other ways you can think of this might be mitigated?

> You would need to trust a single publisher with a technology that’s allowing them to crank out millions of entries and updates permanently, so fast that you could never detect subtle changes or errors or biases targeted in a specific way—and that doesn’t even account for most people, who never even bother to question an article, let alone check the sources.

How is this different from Wikipedia already? It seems that if the frequency of additions/changes is really a problem, you can slow this down. Wikipedia doesn’t just automatically let every edit take place without bots and humans reviewing changes

And people shouldn't be constantly buying mechanical keyboards and keycaps for farming social media karma and affirming their identity when they probably only have a few devices that need keyboards anyway. There's a whole rabbit hole of vice out there if you're interested in looking.

While we're at it, I propose a Board of Ethically Allowed Activities that make sure we can only do the good and moral things.

They do not apply reinforcement learning, which is what most people mean when they talk about reasoning LLMs. This means it is not comparable to the frontier reasoning models.

Here is the post I remember seeing: https://www.reddit.com/r/singularity/comments/1ip3vpa/multid...

This shows that o3-mini has >90% accuracy at multiplying numbers up to 8-digits, and it is capable of multiplying numbers much larger than that. Whereas, gpt-4o could only multiply 2-digit numbers reliably.

Here's another person I saw experimenting with this: https://sanand0.github.io/llmmath/

That's not to mention that if you give these models a Python interpreter, they can also do this task perfectly and tackle much more complicated tasks as well. Although, that is rather separate to the models themselves being able to apply the reasoning steps to multiply numbers.

In October alone I seen 5+ articles and comments about multi-threading and I don't know why

I always said if your code locks or use atomics, it's wrong. Everyone says I'm wrong but you get things like what's described in the article. I'd like to recommend a solution but there's pretty much no reasonable way to implement multi-threading when you're not an expert. I heard Erlang and Elixir are good but I haven't tried them so I can't really comment

The requirement is that the futures are not separate heap allocations, not that they are inert.

It's not at all obvious that Rust's is the only possible design that would work here. I strongly suspect it is not.

In fact, early Rust did some experimentation with exactly the sort of stack layout tricks you would need to approach this differently. For example, see Graydon's post here about the original implementation of iterators, as lightweight coroutines: https://old.reddit.com/r/ProgrammingLanguages/comments/141qm...

But if you want to outlaw this harmful activity [licensed gambling], you have to find a way to replace 6.4% of Maryland’s budget, which is slightly less than the entire amount the state brings in from corporate taxes.

A fraction of the proceeds of losing bets from a fraction of Maryland's citizens contributes almost the same to state services -- EMS, education, road maintenance, etc -- than the total corporate taxes levied on all businesses.

Do I misunderstand, or is this just actually incredible?

So there's a distinction between a task and a future. A future doesn't do anything until it's polled, and since there's nothing special about async runtimes (it's just user level code), it's always possible to create futures and never poll them, or stop polling them.

A task is a different construct and usually tied to the runtime. If you look at the suggestions in the RFD they call out using a task explicitly instead of polling a future in place.

There's some debate to be had over what constitutes "cancellation." The article and most colloquial definitions I've heard define it as a future being dropped before being polled to completion. Which is very clean - if you want to cancel a future, just drop it. Since Rust strongly encourages RAII, cleanup can go in drop implementations.

A much tougher definition of cancellation is "the future is never polled again" which is what the article hits on. The future isn't dropped but its poll is also unreachable, hence the deadlock.

I don't know if this is why, but: he's in a unique position of having an article on himself on Grokipedia, and thus being able and willing to compare it with the reality as he remembers it.

That's in contrast to other topics, the nuances of which even seasoned experts could disagree about. Any discussion on that could devolve into the nuances of the topic rather than Grokipedia itself. But it's fair to assume the topmost expert on Tim Bray is Tim Bray, so we should be getting a pretty unbiased review.

As such it could be a useful insight into how Grok and Grokipedia and its owners operate.

We’ve built more tools for AI agents than anyone — Gmail, Slack, Jira, Notion, Drive, Salesforce — all running securely through Arcade.

After building hundreds of MCP servers, we noticed the same pattern: they all worked perfectly until you tried to deploy them.

OAuth tokens leaked into logs. Secrets ended up hardcoded. Multi-user context melted down as soon as a second person joined.

So we built the thing we wish we’d had from the start — the Secure MCP Framework.

It’s an open-source framework for running production-ready MCP servers with:

- Real OAuth flows (no copy-pasted examples)

- Secrets that never touch the LLM or client

- Built-in token refresh and multi-user context

- Local-first evals so you can test before deploying

Everything runs securely — tokens handled server-side, auth scoped per user, context managed automatically. The LLM never sees credentials.

Why it matters: Most “agents” look great in demos and die in production because of basic security issues. We built Secure MCP so you don’t have to rebuild your server every time your CISO finds a token in the logs.

Works anywhere: Cursor, VS Code, Claude Desktop, ChatGPT, or your own MCP client.

I think you’re right - some people will gamble no matter what, but removing all barriers to entry and advertising it on ESPN will certainly grow that market much more than people actively seeking out betting in shady places online.

It’s similar to weed legalization 10 years ago. Yes, it’s now much less likely that your weed will be spiked with meth or you will be robbed by your dealer, but also like 1000% more of the population smokes weed now and it has some bad social side effects that people don’t like to think about.

I think in both cases, as with prohibition, making something commonplace illegal again tends to make people do crazy things if they’re addicted, and I’d bet gambling is no different

Was that always the case? I took from TFA that some number are purely hereditary and that all of them used to be before a recent reform.

Or was it that one has to be a hereditary peer in order to be a government appointee?

Either way, the greater the barrier to the house of sober second thought being stacked by whoever is currently in power, the better. I’d also favor people being randomly appointed for life.

I started with Debian on CDs, but used Gentoo for years after that. Eventually I admitted that just Ubuntu suited my needs and used up less time keeping it up to date. I do sometimes still pull in a package that brings a million dependencies for stuff I don't want and miss USE flags, though.

I'd agree that the manual Gentoo install process, and those tinkering years in general, gave me experience and familiarity that's come in handy plenty of times when dealing with other distros, troubleshooting, working on servers, and so on.

> I always said if your code locks or use atomics, it's wrong. Everyone says I'm wrong but you get things like what's described in the article.

Ok so say you are simulating high energy photons (x-rays) flowing through a 3d patient volume. You need to simulate 2 billion particles propagating through the patient in order to get an accurate estimation of how the radiation is distributed. How do you accomplish this without locks or atomics without the simulation taking 100 hours to run? Obviously it would take forever to simulate 1 particle at a time, but without locks or atomics the particles will step on each others' toes when updating radiation distribution in the patient. I suppose you could have 2 billion copies of the patient's volume in memory and each particle gets its own private copy and then you merge them all at the end...

That assumes our knowledge of Detroit is more informed that yours of the UK ;-)

Generally there is a lot of propaganda around at the moment, so take that with a pinch of salt. The UK is not as well off as the US generally, but this does not mean there is a breakdown of society or law and order.

The propagandists would have you believe that there is a massive crime wave and social breakdown due to immigration, but what people are mostly worried about in actuality is job uncertainty and backlogged public services.

There are areas of wealth and of deprivation both inside and outside London. There is political and economic uncertainty because the UK economy is imbalanced, and most people expect a difficult few years and are sceptical that the government knows how to fix the issues (and that vested interests won't prevent the solution)

I would definitely use this to knock together quick prototypes before ordering boards from China.

So many times that I’d happily pay $20 to try a board right fricking now (and I doubt they’ll be $20 all-in).

For me, it would replace breadboarding, not replace a final prototype PCB before committing to a first assembly run.
by wrs | 2025-10-31 23:53:45+00:00
It's hard to answer the question because of unclear terminology (tasks vs. futures). There are ways to do structured concurrency in Rust, but they are for tasks, not futures. There's not really a concept of "active futures" (other than calling an "active future" one that returned Pending the last time you polled it).

A task is the thing that drives progress by polling some futures. But one of those futures may want to handle polling for other futures that it made, which is where this arises.

As the article says, one option is to spawn everything as a task, but that doesn't solve all problems, and precludes some useful ways of using futures.

It's a shame there aren't US manufacturers who can manufacture custom PCBs as cheaply as JLPCB or PCBWay.

These types of lasers might be a stopgap if tariffs make buying from those companies inordinately expensive, however the extreme cost, and the need to do a bunch of cleanup kind of makes me suspect there needs to be another iteration of this tech.

This is a somewhat silly question because you could probably get anecdotal replies of all kinds to it. Some things are different to how they used to be, and in some cases different in ways that feel bad. For example, there are more empty shops in the town centre where I live compared to 20 years ago, which for some people evokes a strong emotional reaction and a sense of loss.

When you say "like Detroit" I assume, having never been, that you mean a high crime rate and unemployment rate? You could visit the ONS: https://www.ons.gov.uk/peoplepopulationandcommunity/crimeand... https://www.ons.gov.uk/employmentandlabourmarket/peoplenotin...

My own personal experience tends to back up what the data here show (no significant changes really) - I teach in a large secondary school and really, kids today are not massively different from how they've ever been. They face challenges in navigating the vast amounts of information and misinformation presented nowadays, but we do try to educate them as best as possible in respect of this.

Cheers and hope this helps.

my argument is that humans are in-fact horrible and there is virtually no argument why enslaving an AGI wouldn't be socially acceptable (like eating meat).

and if someone doesn't do it, there will be people that will and due to the nature of AGI being extremely powerful (in theory) everyone else will just get enslaved by whoever enslaves the AGI first.

No. I don't think I am mischaracterizing it and I did not say the whole world is biased against me. I am not the person you replied to in case you're confusing me with them. I gave an example of an astroturfing campaign and yes, the ADL did not disclose what they were doing until they got caught. I don't think that should be casually dismissed as merely just interested parties. I think it is a genuine problem with Wikipedia. I think it violates the spirit of it and I think a paid campaign could subtly influence or overwhelm pages even though it's perfectly within the rules it should be disclosed the edits were done as part of a paid campaign and not a volunteer effort. I did not claim Wikipedia was centralized either. As far as gatekeeping I don't know. I am neither claiming it exists nor denying it.

> What if I told you a single person, soon to be a trillionaire, would like to replace it with one he controls himself. Why wouldn't that bother you more?

I didn't say anything about Grokipedia. I don't have an opinion on it presently. Couldn't the same argument be applied that he's just an interested party? Grok could be used to edit Wikipedia for that matter in a covert campaign. I think both preventing LLMs and relying on them are problematic but it's probably inevitable and I may already be late to the party because I don't know what percent of edits are done by LLMs on Wikipedia but let's say it's not 0%.

So I discovered Wispr Flow a bit ago, and it has been quite game changing in how I vibe code or just generally interact with AI. However there are a few fundamental drawbacks I didn't appreciate: - All your data is sent to the cloud (you certainly want your company's approval before using) - $12/mo subscription?? (why does everything have to be subscription nowadays)

So I created a FOSS alternative that works basically just as well at in my fundamental usecase: getting Claude Code or some other AI to understand what I want. For that we don't need massive cloud infrastructure or precise formatting, just one that gets the ideas right.

Comes Transcrybe: - Free and Open Source - You choose your own model (currenly between Whisper Tiny, Base, and Small) - Instant Dictation <1s even for long sentences - Zero data uploads eliminates privacy concerns (all recordings are deleted post dictation)

Of course it certainly doesn't format or recognize obscure language as well as a well-funded startup solution like Wispr Flow, but in my testing it is basically just as good in many usecases.

Check it out: https://github.com/spacefarers/Transcrybe

I am building on the shoulders of giants thanks to the incredibly fast C++ framework provided by whisper.cpp!

Go to https://ui.perfetto.dev/. On the left sidebar, under "Example traces", click "Open Android example".

For a simple example using your own data, save this as a file and open it via "Open trace file":

[ {"name": "Example 1", "ph": "X", "ts": 1, "dur": 1, "pid": 0, "tid": 0}, {"name": "Example 2", "ph": "X", "ts": 3, "dur": 2, "pid": 0, "tid": 0}, {"name": "Example 3", "ph": "X", "ts": 2, "dur": 1, "pid": 0, "tid": 1}, {"name": "Example 4", "ph": "X", "ts": 4, "dur": 2, "pid": 0, "tid": 1} ]

I have a Mac Studio with the M4 Max and 128GB RAM

The Qwen3-coder model you use is pretty good. You can enable the LM Studio API and install the qwen CLI and point to the API endpoint. This basically gives you functionality similar to Claude code.

I agree that the code quality is not on part with gpt5-codex and Claude. I also haven't tried z.ai's models locally yet. I think on a Mac with that size GLM 4.5 Air should be able to run.

For README generation I like gemma3-27b-it-qat and gpt-oss-120b.

Thanks. To be more specific on what I’ve seen by YouTubers touring outside London is just boarded up shops, minimal economic hope, lots of abandoned homes again outside London. The narrative being essentially the de industrialization having now gutted the entire economy except for the well off and financial services etc. which of course shocked me cause I always pictured England as quite wealthy and having made that transition out of factory economy quite well. Which then led me to wonder if Britain is just just a few years ahead of the rest of us.

In fact there was a lot of churn and drama. What we have left today in the UK is literally the result of survivor bias.

A lot of country houses are now state-owned, managed through nominal charities. Quite a few disappeared in the 20th century.

The British aristocracy is a complex thing, with came-over-with-the-Normans at one extreme, and relatively recent self-made opportunists at the other. It's a socio-archaeological phenomenon in its own right - influential, but under-researched, and opaque to outsiders.

The 10th amendment restrains what the federal government can do. By taxing and administering SNAP, they deprive the states and people the rights reserved to them by the constitution. The federal powers are pretty narrow, and the amount of taxes that can be sustained upon the populace finite. By usurping taxation and distribution of extra-constitutional federal powers, they deprive states the ability to administer it themselves.

Sports betting is only one form of gambling, so I have no idea what you're talking about. This article, like your post it seems, is conflating the two and mixing in vague assertions of corporations and whatnot to add a layer of emotion that serves more to manipulate than to elucidate.

There's always been gambling in my lifetime. There's been legal ones like Indian Casinos and Vegas. Then there's been the below board ones, the private blackjack games, the mahjong parlors in shady parts of town, lottery players (it's okay if the government profits off the losers I guess lol), etc

If this article were talking about banning sports books and adding in regulation around retail betting then sure that would be a fun discussion. But hyperbole like the article and your copious use of exclamation points doesn't inspire confidence.

GrapheneOS makes security trade-off that are inconvenient to the user. This results in a far more secure device, but nonetheless a device that the general public would find far more annoying. Google would lose a proportion of its user base by implementing the same protections.

Example: https://old.reddit.com/r/GooglePixel/comments/ytk1ng/graphen...

Also Google Pay is missing.
