For me this cancel and restart thing e.g. in ChatGPT is so annoying. Plus most chat tools don't even get your second message if you send it before they finish, so you're locked into waiting. And in this coyote approach I can just add more context if I forgot something and it picks it up without cancelling what's already running. It' s more like talking to human.

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

And one thing became obvious – if you’re serious about agents, you eventually need your own MCP server.

That’s why we wrote a Custom MCP Server Framework — a step-by-step guide to spin up an MCP-compliant backend that can power your own tools, services, or internal APIs.

It covers:

- Spinning up a server that speaks the Model Context Protocol (MCP)

- Exposing tools via standard endpoints (/context, /tools, /call, etc.)

- Handling authentication, state, and user context correctly

- Deploying beyond localhost — production-ready in minutes

Why it matters:

Most agent frameworks stop at “tool calling.” But the real challenge is the backend — managing identity, context, and persistence across thousands of tool calls.

With an MCP server, your agents can:

- Connect to any system — SaaS or internal — through standardized interfaces

- Enforce permissions and context per user

- Scale from prototype to production without rewriting core plumbing

Why we care:

At Arcade.dev, we’re pushing to make MCP the open standard for connecting agents and tools. Our platform already runs thousands of tools — this guide shows how to make it your own.

The Senate is not subject to garrymandering and if we fixed the issues with the House (literally via any mechanism) the Senate would immediately go back to being the vehicle used to prevent the will of the people (see the Senate under Mitch McConnell any time the House was under Democrat control)

Until the Dem party fixes their brand and wins back some of the Senate seats they used to control in the 90s and early 2000s there will be no positive progress.

Cookies shouldn't be tied to domains at all, it's a kludge. They should be tied to cryptographic keypairs (client + server). If the web server needs a cookie, it should request one (in its reply to the client's first request for a given url; the client can submit again to "reply" to this "request"). The client can decide whether it wants to hand over cookie data, and can withhold it from servers that use different or invalid keys. The client can also sign the response. This solves many different security concerns, privacy concerns, and also eliminates the dependency on specific domain names.

I just came up with that in 2 minutes, so it might not be perfect, but you can see how with a little bit of work there's much better solutions than "I check for not-evil domain in list!"

Speaking of which, what the fuck is wrong with product managers at big tech these days?

When I try to express:

> I don't want to see ANY shorts

instead, I get:

> show me fewer youtube shorts

when I want to say:

> NO

I'm only allowed to say:

> mAyBe LaTeR

Do the people behind these design decisions not realise they're monsters by gagging their users into only being able to express notions that appease them?

Single client, I'm getting ~5GB/s, both on an 8-year-old intel server, and on my M1 ARM chip.

However with a single server, it doesn't perfectly linearly scale with multiple clients. I'm getting

1 client: 5GB/s

2 clients: 8GB/s

3 client: 8.7GB/s

I have my browser set to clear cookies and site data automatically, so I'm not sure if my experience of YouTube shorts is typical, but I have a pet theory about why the feelings you describe are so common. It seems like a big part of the addictiveness is not that the content is eye-catching, although this clearly has an effect. The platform gives you a quick way to move onto something else by scrolling/swiping, which means I find myself caught in a cycle of:

1. seeing AI slop or a unoriginal 'comedy' sketch,

2. thinking "eww get this off my screen",

3. scrolling down to the next video; jump to step 1

On the rare occasions that the algorithm does show something genuinely interesting or creative, I watch to the end of the video and feel a lot more satisfied about spending time on it. That's not to say that long-form videos can't be distracting and addictive, but I would posit that 'shorts' engagement is actually driven by disgust rather than curiosity. I now avoid YouTube shorts like the plague, because life is too short to experience that volume of disgust in it.

Some of us came here because we were finding programming.reddit.com too mainstream (after all this thing was written in Arc! of which almost no-one knew any details for sure, but it was Lisp, so Lisp cool), for sure we weren't visiting this place in order to become millionaires.

Even though I agree, there was a time and a place (I'd say 2008-2010) when this forum was mostly populated by "I want to get rich!" people, maybe that is still the case and they've only learned to hide it better, I wouldn't know.

But if Musk left Tesla and the stock plummeted, Musk's wealth would also plummet (Tesla is ~1/3 of his publicly known wealth). So I don't think leaving Tesla is in his interest even if it were voted that he will never get any compensation. If Tesla's value increased, his wealth would also greatly increase, so he should be motivated anyway. With that in mind, other stockholders may vote against the package even if they want him to stay, because it's not in their interest to have their shares diluted to give even more shares to Musk.

So I’ve always had this weird obsession with building my own iMessage agent - like, imagine your own bot living inside your iPhone, sending messages, replying smartly, maybe even trolling your friends a little

Then I found out companies like Linq Blue and SendBlue (both YC) charge over $1000/month just to do this. Yeah, no thanks.

So I built it myself.

iMessageKit is an open-source TypeScript SDK that lets you send and operate iMessages programmatically. Texts, photos, even RCS messages - all through a clean, strongly typed API.

Now I can build iMessage bots and automations without burning cash, and honestly, it feels great to beat the paywalls.

Would love feedback & ideas!

“It is not that we have a short time to live, but that we waste a lot of it. Life is long enough, and a sufficiently generous amount has been given to us for the highest achievements if it were all well invested. But when it is wasted in heedless luxury and spent on no good activity, we are forced at last by death’s final constraint to realize that it has passed away before we knew it was passing. So it is: we are not given a short life but we make it short, and we are not ill-supplied but wasteful of it… Life is long if you know how to use it.”

Science and Faith have different goals. Science figures out things, Faith helps those who are alone (And your ego hates this). Both are, in a neutral, scientific, sense, cults.

Edit: I am a bit one-sided here. Faith also is a social glue (look e.g. at the Muslims), and it actively works for spiritual self determinism. At least Buddhism, Toltecism and Scientology do.

And those are some very low hanging fruit. If you look at the bigger picture, Apple does not know how to balance ease of use on the one hand and control over details by power users/geeks on the other hand. They simply do not let you configure things, because coming up with good UI for that is hard. But on macOS, power users probably make up a large share of their users. They should figure this out.

And these are not new issues, they've been known for more than 40 years, but never addressed. From the 1983 Led

> But even though radiation damage rates and heat transfer requirements are much more severe in a fusion reactor, the power density is only one-tenth as large. This is a strong indication that fusion would be substantially more expensive than fission because, to put it simply, greater effort would be required to produce less power.

What domain are you working in? It's hard to be able to say anything specific that might help you if you can't explain a little more clearly what you're working on.

I will say there are a larger and larger number of no-GC libraries. Phobos is getting an overhaul which is going to seriously reduce the amount that the GC is used.

It is probably also worth reflecting for a moment why the GC is causing problems for you. If you're doing something where you need some hard-ish realtime guarantee, bear in mind that the GC only collects when you allocate.

It's also possible to roll your own D runtime. I believe people have done things like replace the GC with allocators. The interface to the GC is not unduly complicated. It may be possible to come up with a creative solution to your problem.

We built what should have been the dream team of AI agents—eight specialists covering the entire development lifecycle. But give them an open-ended project and they'd spin in circles asking the same questions. The solution wasn't in the models, but in how humans work best: with clear finish lines. After watching our agents flounder for months, we realized they needed the same thing effective teams do: concrete goals with defined boundaries. When we stopped saying "build an e-commerce site" and started assigning specific deliverables with measurable completion criteria, they transformed from constantly confused assistants into capable, autonomous specialists. The same systems with the same capabilities suddenly performed at an entirely different level, simply because we changed how we structured their work.

It doesn't matter whether they realize it. Even if they do, they just don't care. Most corporate leaders have high degrees of psychopathy. They are exclusively focused on their profits and nothing else. If gagging their users makes them more money than not gagging their users, they will gag their users and they will spare zero thought on how the users might feel about being gagged.

From fiction, we have Clancy's sudden loss of the majority of federal elected officials which allowed for a fresh start. However, that's subject to having governors submitting senators while having elections for congress. Starting from a clean slate would be the only fix. As it is now, it's who is willing to kowtow to the biggest backers to get them over the line and stay in office. On top of the gerrymandering that all but ensures the party in control stays in control, I see no change to the status quo in my life time without an uprising.

I don't disagree, but they really are a different beast. Have you used the shorts feature? It's 95% brainrot. Where as you can use youtube intelligently to watch interesting things if you choose to. Obviously you could use regular youtube and watch brainrot/slop too, but there is no way to use shorts to watch good content.

>So top of the list for us, of course, designing this thing is safety.

Funny issue I learned after talking to a founder at a similar company: although the battery packs were certified safe for cars (passing crash tests, wild heat differences from AK to AZ, people sitting on top of the battery packs in the car) ... the founder had issues re-certifying the batteries for safe use in a static location for grid storage.

The certification process treated his company like the batteries were made from scratch even though they used the same BMS/coolant lines/etc. already proven and tested.

It's clear you still need strong safety regulations and practices in the rare case there's an event, but the founder noted the grid storage industry regulations were adding redundant safety testing and slowing down adoption. The founder also added it's difficult to compete on cost even with effectively free used EV batteries in this startup space of grid storage against the low cost of Chinese made grid-specific batteries due to the added testing + custom hardware + space constraints and other items. (Caveat: I didn't fact check any of their statements)

In an ice storm and cold cloudy snap that sweeps the country, NO lithium batteries will save the grid. I'm weary of this tunnel vision of the absurd. The only 'storage' that works is to pump water uphill with 'surplus' energy, and there is not and never will be a surplus. And these evaporartion tanks are on a scale that ecologists have to remember countless horror stories (eg., Glenn Canyon Dam). And of course there's always "mfft!" (another scheme with no numbers behind it so it's credible because I'm talking about it).

The last time there was anything rational on the table was Perry under the Trump administration's 30-day rule proposal ( https://www.nucnet.org/news/nuclear-is-vital-to-us-national-... ). It gave a hard industry incentive to any energy supplier who can have 30 days' fuel on site. This means nuclear and coal. This was no gimmick, it was the first time anyone faced reality about National Security as related to Energy for the grid and survival. And now AI datacenter yadda yadda, we're also talking about the luxury of keeping schools heated in Winter. Adverse weather even for a week is grid down game over for wind and solar. Proven natural gas are ~300 years, joy! As soon as they get around to sending pregnant whales across the ocean (losing ~20% of the gas-energy in cooling) it may even last 50 years! Before we have to go to endless war again.

attention required: 10 minute video > 10 second short

When the written word took over with the printing press, the same concern was levied. The amount of attention required to listen and memorize a story/poem is a lot more than just reading it.

The change with smart phones is just one of access/time spent on these things. There are people who are spending ~5 hours/day watching this content. There is a big difference between someone listening to 5 hours of a single poem, to reading 5 hours of a single book, to reading 5 hours of blog posts, to watching 5 hours of a youtube video, to watching 5 hours of random videos, to 5 hours of <10s videos.

Writing shell completions is tough: bash, zsh, and fish each have different, complex syntax

scog aims to solve this: you write one simple YAML file describing your CLI and it generates proper completion scripts for all three shells.

It's built on clap's battle tested generators, so you get proven, quality completions without maintaining shell-specific scripts

Suggestions welcome ;)

Maybe the thought is that there will be more pressure now on getting all the tests to pass given the larger install base? It isn't a great way to push out software, but it's certainly a way to provide motivation. I'm personally more interested in whether the ultimate decision will be to leave these as the default coreutils implementation in the next Ubuntu LTS release version (26.04) or if they will switch back (and for what reason).
by gwern | 2025-10-23 22:50:51+00:00
This is the epitome of patching symptoms rather than treating the disease. Even if you suppress the obvious syntactic slop like 'it's not X but Y', you have no reason to believe you've fixed mode-collapse on higher more important levels like semantics and creativity. (For example, Claude LLMs have always struck me as mode-collapsed on a semantic level: they don't have the blatant verbal tics of 4o but somehow they still 'go in circles'.) Which will potentially severely hinder the truly high-value applications of LLMs to creative applications like frontier research. To the extent that this succeeds in hiding the brain damage in contemporary LLMs, it arguably is a cure worse than the disease.

You missed what I stated, pardoning someone for a specific crime vs what biden(if he was actually doing it) pardoned his son for all crimes he may have done over a 10 year span. Oh wait, that was actually one of the only pardons he actually signed.

edit:

He actually pardoned 5 family members for all non-violent offenses from jan 2014 to jan 2025, does 1 billionaire = 5 biden family members?

I don’t really follow what you are suggesting. If the system is complex and constantly evolving as the article states, you aren’t going to be able to close any expertise process gap. Operating in a degraded state is probably already built in, this was just a state of degradation they were not prepared for. You can’t figure out all degraded states to operate in because by definition the system is complex

I understand that being a fork of Snowplow is how you define yourself, but there's actually nothing on the webpage that provides any detail of what the product does, other than "event pipeline" right up the top.

I suggest putting at least some content on the website about what you do so that people can find you when looking for solutions in the industry, rather than having them adopt Snowplow and then splinter off later. I understand that your main focus is snowcatcloud.com which does have info putting some on opensnowcat.io will greatly enhance its discoverability.

Especially as the splinter strategy is going to become increasingly harder as people who care about open source won't adopt Snowplow to begin with, and people who don't care won't leave it.

Very chill :)

I do this at an industrial scale. It gets really annoying as you scale up to hundreds / thousands of different strains, all of which need pickable colonies.

A serial dilution 3 or 4 times seems to always do the trick. Typically on a robotic workstation you have to aspirate 6.5uL, then slowly dispense 5.5uL above the Petri dish (sbs format) and then stab into the agarose. Makes lovely perfectly-sized and separated wells, so 96 cell lines fit on only 3 or 4 plates.

With better plate reading you can get that down to 1 or 2 plates but it’s less reliable

Maybe I have my feed tuned really well or I subconsciously just ignore the slop, but these days I find that a lot of the time Shorts are more helpful than full length videos which, I guess for ad reasons, are so heavily padded out that it can be a chore to get to the meat of it. Also the little short "previews" of full length videos let me know if I should bother with the full length one or not.

There is definitely some slop there, but I've overall found it more useful than not.

I think car cells will be much more useful if they are packaged as replacement batteries for all the various battery powered tools, ebikes, etc.

There's a consumer profit margin to absorb the repackaging and teardown.

Maybe for home grid batteries they'll work too. Again, a consumer margin.

Sodium Ion and other grid-specific storage will simply be too cheap for secondhand EV batteries to compete. And the retiring cells won't be any better in density and will be less safe than the higher density sodium ion and LFP that is hitting the market.

I notice this less with GPT-5 and GPT-5-Codex but it has a new problem: it'll write a sentence that mostly makes sense but have one or two strange word choices that nobody would use in that situation. It tends to use a lot of very dense jargon that makes it hard to read, spitting out references to various algorithms and concepts in places that don't actually make sense for them to be. Also yesterday Codex refused a task from me because it would be too much work, which I thought was pretty ridiculous - it wasn't actually that much work, a couple hundred lines max.

Gambling is also extremely successful but you could argue it's a net loss for society to have it.

The argument that money == correctness is basically what we've been trained to believe by armies of MBAs, but it's not right. It's sad that the state of philosophical and moral discussions in our society has basically been usurped by a kind of thoughtless reductionism.

What are we debating? Does anyone know?

One claim seems to be “people should cease using any anthropocentric language when describing LLMs”?

Most of the other claims seem either uncontested or a matter of one’s preferred definitions.

My point is more of a suggestion: if you understand what someone means, that’s enough. Maybe your true concerns lie elsewhere, such as: “Humanity is special. If the results of our thinking differentiate us less and less from machines, this is concerning.”

These Keccak derived hashes are my personal favorite hashes. The Keccak sponge function is a more advanced mathematical foundation of hashing than what we had before. The individual mixing functions were also carefully chosen to do very different things. My favorite attribute, however, is that all the cryptanalysis done on SHA3 maps directly to Keccak (unlike Blake's follow-ons).

I forgot where I read it, but there's apparently a Jobs policy of "one standard and two proprietary ports" or something, so to allow data to be ingested easily and freely shared inside Apple ecosystem, but not exported back out to the outside world with same ease.

Which is like, a great way to subsidize junk USB hubs...? But for sure they love following through with policies.

Let me stop you right there. MiniIO never promised to provide docker images for free forever, have they? So where does this "expectation" come from?

If thou are pained by any external thing, it is not the thing that disturbs thee, but thine own judgment about it. And it is in thy power to wipe out this judgment now. (Marcus Aurelius, quoted in Beck, 1976, p. 263)

I've also lived through that era and used OS/2 extensively. Display drivers were always the weak point of the system.

At one point, after a very prolonged struggle, I managed to get 800x600 resolution working (standard was 640x480). The gigantic sense of achievement I felt at that moment hasn't been repeated in 30 years hence.
