Very impressive results, cool to see innovation in this space! I’d definitely be interested in a follow up post going into the details of the geometric algorithms.

I’m working on my own DGGS, A5, the first (and only) to use pentagons. It offers true equal area cells and a much higher cell fidelity (below 1cm compared to 1m for H3).

I’m looking for contributors to get involved and you seem to have the perfect skill set. It would be amazing to have you join the project :) https://a5geo.org/ https://github.com/felixpalmer/a5

Well, he's one of the most famous and best-respected educators of linear algebra, and this is an unusually basic piece of linear algebra to be taking aim at him for, so one answer is: if you have to ask whether his approach is defective, you should first evaluate how strong your own understanding is. That's argument from authority, but then: Strang is an authority. The typical push-pull on a message board is between Strang and Axler, and, if you want to find out if Axler is going to save your argument, flip to 6.A in LADR.

The direct response to your question is: the centrality of the angular interpretation of the inner product is the kind of thing I feel like you'd say if your primary purpose for learning linear algebra is to program video games. Linear algebra isn't "about" geometry, and, in particular, Strang's teaching goal centers vector spaces and the relationship between spaces. You need inner products to apply linear transformations with matrices. You basically don't need the angular interpretation... at all? if your goal is to teach linear algebra as a tool for data manipulation and, as Strang did in his last course, as a vehicle for deep learning.

(You need orthogonality, but you didn't say `a⟂b=0`, you said `|a||b|cosθ`).

I'm not rating this blog post "higher" than 3B1B; the comparison doesn't even make sense. The blog post and the video series simply have different objectives.

The last one is fairly simple to solve. Set up a microphone in any busy location where conversations are occurring. In an agentic loop, send random snippets of audio recordings for transcriptions to be converted to text. Randomly send that to an llm, appending to a conversational context. Then, also hook up a chat interface to discuss topics with the output from the llm. The random background noise and the context output in response serves as a confounding internal dialog to the conversation it is having with the user via the chat interface. It will affect the outputs in response to the user.

If it interrupts the user chain of thought with random questions about what it is hearing in the background, etc. If given tools for web search or generating an image, it might do unprompted things. Of course, this is a trick, but you could argue that any sensory input living sentient beings are also the same sort of trick, I think.

I think the conversation will derail pretty quickly, but it would be interesting to see how uncontrolled input had an impact on the chat.

The fact that you try to elide the difference between nebulous and magical (perhaps subconsciously), is proof that you have no idea what you are talking about and project that on all your interlocutors. And your claim that people who are trying to argue that LLMs cannot think are all excluding a section of humanity just reveals your own disdain for said people. If you have a purely functionalist, egotistical view of the world, and people only matter in as much as what they can do for you, it's very easy to embrace LLMs without issue because you never really had a theory of mind in the first place.

Not really...

That assertion seems to be a disconnect of language. But - Selling firearms in Wal-Mart is bad enough, but it does tend to be more rural Wal-Marts than suburban (and not at all urban).

Said firearms are under lock and key in the same way they would be at gun stores. There are many gun shops in the same areas where Wal-Mart sells firearms. At least - where I live, which is a blue state. All bets are off for Texas.

"If AI labs wanted to go beyond that, they’d have to go and buy older books, which would probably have more em-dashes."

Actually, they wouldn't have to go and buy these old books: The texts are already available copyright free, due to legislation stating that copyright expires 70 years after the author's death (any book published in the USA before 1923 is also reproducible without adherence to copyright laws), making the full texts of old books much easier to find on the internet!

Damned if you do, damned if you don’t. I think Wikipedia would do really well for itself if it instead created a set of public high level rules for an open model to follow. The model would write the article using all publicly available information. This would enable the article to feature all perspectives on the issue to avoid “lying by omission”. Articles would instead be overviews and about a topic rather than appearing biased to a particular set of talking points and coverage. Summary is much more approachable and benefits people who want to learn all about a topic rather than those who seek confirmation reinforcement. I think the end result of this would be that people would be equally happy/unhappy with Wikipedia because the rules would be applied to every article equally and would be a place to go when users didn’t know what to prompt while apps like Grok/ChatGPT are resources used when people already have a question prepared. I agree with Jimmy’s opinion that Wikipedia is not a place to adjudicate disagreements.

how many thousands? I have a folder with a total of 12760 files spread within several folders, but the largest I think is the one with 3827 files.

I've noticed the sync isn't instantaneous, but if I ping one device from the other, it starts immediately. I think Android has some kind of network related sleep somewhere, since the two nixos ones just sync immediately.

It started innocently enough. Scrolling through Instagram one evening in early 2025, I stumbled upon a sponsored post promising sky-high returns on crypto investments. The account, @CryptoWealthPro, flaunted testimonials, flashy charts, and limited-time opportunities in Bitcoin and Ethereum. As a middle-aged teacher with modest savings, I dreamed of early retirement. I messaged them, and soon a financial advisor named Alex guided me through a sleek app to transfer $20,000 from my bank. Initial profits appeared, luring me to invest more, another $35,000. Then, poof. The app vanished, withdrawals failed, and Alex ghosted me. I'd fallen for a classic pig-butchering scam, my life savings of $55,000 gone in digital smoke. Devastated, I reported to the police, but they said cross-border crypto frauds were tough to crack. Online forums like Reddit's r/scams echoed my despair, with victims sharing horror stories. Amid the gloom, one name kept popping up, Alpha Spy Nest (ASN), a team of forensic experts specializing in blockchain recovery. Skeptical after my trust betrayal, I visited alphaspynest.org. Their site detailed services, digital forensics, transaction tracing, and legal coordination. Reviews on Brainly and DiscussionBucks praised their success in similar cases. Desperate, I emailed alphaspynest@mail.com, attaching transaction details. Within hours, they responded. We've seen this Instagram ploy before fake profiles funneling funds to mixer wallets. ASN's team, comprising ex-cyber cops and blockchain analysts, swung into action. They used proprietary tools to map my transfers, from my wallet to a scam exchange, then tumbled through anonymity services. Over a week, they gathered evidence, IP traces, wallet histories, and even linked the scammers to a Southeast Asian ring. Collaborating with international authorities, they froze assets and initiated reversals. The breakthrough came when ASN uncovered a vulnerability in the scammers' setup of a traceable endpoint wallet. Through legal channels, they recovered 85% of my funds, $46,750 deposited back into my account. The rest covered fees, but it was a miracle. Today, I'm rebuilding, wiser. ASN didn't just recover money, they restored hope. If you're scammed, don't wait, contact pros like them. Beware Instagram lures, verify everything. My story? A cautionary tale turned to victory, thanks to Alpha Spy Nest's expertise.

Why would you want to restrict yourself to a one-dimensional mentality of commits when the source control system handles two-dimensions naturally and well? It seems to me a bit like wanting to only use about half the tools that you have available.

Squashes and Rebases delete information entirely out of source control. If a PR adds 100 lines of code, then deletes 50 of them and you squash it, you've lost 50 lines of code. Once your PR tool garbage collects those original commits you can't easily get it back. Maybe that's fine and that was garbage code anyway, but it was part of the process of getting those 50 lines you kept and could be relevant to questions of "why were these 50 lines added?" Were those other 50 lines alternatives that were rejected in testing, perhaps? Worse, were they deleted on accident in a bad inner merge and not caught in time?

I feel a lot less confident in the YAGNI code tossing that Squashes and Rebases do. I've had too many times where I've needed to code dive a fix out of a Merge commit or out of a long winding PR that went through several alternatives.

Git provides some great 2D navigation tools such as `--first-parent`. You can have "I just want a view of PR merges" and the structure of "the commits below that PR are accessible, too". I can't see why you wouldn't want that. That's what source control is for, "save all the minutia in case I need to find it again someday" and it is just a UI problem if you don't want the 2D view by default.

I think the "subway diagrams" that most git UIs show look pretty, especially in screenshots, but are not the UI most people actually want to work with day-to-day. I think a lot fewer people would be so adamant about squash-only or rebase-only workflows if more git UIs took a "1D" first view of the git DAG instead of "subway views". I think more git UIs should start with `--first-parent` and provide drilldown into "lower" commits instead.

I think I see this point now. I thought of YAGNI as, "don't ever over-engineer because you get it wrong a lot of the time" but really, "don't over-engineer out of the gate and be thankful if you get a chance to come back and do it right later". That fits my case exactly, and that's what we did (and it wasn't actually that painful to migrate).
by ludicity | 2025-11-03 19:49:53+00:00
This is a good take. In the consulting context, I've quickly realized that most problems at a business can be broken down into "this will destroy the project on its own" and "this is an annoyance to a good engineer". Language choice is basically always in the latter category, whereas poor management or one egotist is frequently in the former.

Like, my team doesn't know anything about Java, but we COULD ship in Java if forced to. We can't ship if the feedback loop is a 30-minute CI pipeline because there is no way to have a local dev environment.

Hunh. It feels weird to say "Language learning apps are always ugly, clunky" and "Apps only ever support the major languages, leaving minority languages in the dust" when those are a few things that Duolingo actually does fairly well. Don't get me wrong, Duolingo has a LOT of flaws and I'm excited to hear you're building an alternative to it, just the pitch feels like it's based on a time when Rosetta was the name to beat.

> I'm so baffled when I see this being blindly asserted. With the reasoning models, you can literally watch their thought process.

Not true, you are falling for a very classic (prehistoric, even) human illusion known as experiencing a story:

1. There is a story-like document being extruded out of a machine humans explicitly designed for generating documents, and which humans trained on a bajillion stories humans already made.

2. When you "talk" to a chatbot, that is an iterative build of a (remote, hidden) story document, where one of the characters is adopting your text-input and the other's dialogue is being "performed" at you.

3. The "reasoning" in newer versions is just the "internal monologue" of a film noir detective character, and equally as fictional as anything that character "says out loud" to the (fictional) smokin-hot client who sashayed the (fictional) rent-overdue office bearing your (real) query on its (fictional) lips.

> If that's not thinking, I literally don't know what is.

All sorts of algorithms can achieve useful outcomes with "that made sense to me" flows, but that doesn't mean we automatically consider them to be capital-T Thinking.

> So I have to ask you: when you claim they don't think -- what are you basing this on?

Consider the following document from an unknown source, and the "chain of reasoning" and "thinking" that your human brain perceives when encountering it:

My name is Robot Robbie. That high-carbon steel gear looks delicious. Too much carbon is bad, but that isn't true here. I must ask before taking. "Give me the gear, please." Now I have the gear. It would be even better with fresh manure. Now to find a cow, because cows make manure.

Now whose reasoning/thinking is going on? Can you point to the mind that enjoys steel and manure? Is it in the room with us right now? :P

In other words, the reasoning is illusory. Even if we accept that the unknown author is a thinking intelligence for the sake of argument... it doesn't tell you what the author's thinking.

Suppose you go from a 95% efficient electric motor to a 99% efficient motor. How much more efficient is it? You might say 1.04x (or actually 99/95 efficient). Except, that's not the whole story - electric motors need cooling, and you've just dropped the heat output five-fold (going from 5% heat to 1% heat). Lower heat output means less venting needed and thus better aerodynamics.

> The main driver of a project's success is almost always driven by: the composition of employees working on the project, and the competence of the people architecting the project.

This is my experience too. I’d go a bit further and say the leads are the primary driver of success. Because ultimately, if the composition of the people on a project is incorrect, it’s the lead’s responsibility to realize and change it.

Nick Fuentes is extreme. Democratic socialism is not extreme, no matter how hard conservatives might try to paint it that way. There is no equivalence here, and "both sides" are not equally to blame.

And other than Mamdani -- a middle of the road democratic socialist who would find himself at home in any Scandinavian country -- I’m not sure what "self-proclaimed socialists" you’re even talking about.

I think it is hugely underappreciated that in most of "the west" we can have public media content that is critical of army/politicians/administration and just makes the nation look bad abroad.

I'm talking less about "free speech" as a concept and more about how the majority still thinks its worthwhile to have and allow such things even if they hurt.

This is not something to take for granted, and I often find people oblivious to this privilege. There were lots of voices arguing along similar lines during the Snowden leaks ("should be punished/swept under the rug because it makes America look bad"), but I think this is truly a cornerstone of a free society, and the concerning thing here to me is not even how the Israeli lawyer or Army acted, but how Israeli public perception is seemingly changing on this.

That's a reasonable take! Yes, there are tradeoffs and there are bad OSS actors (like Bitnami) that make it hard to state anything in this realm as a hard truth.

In this article, I'm fairly focused on the Terraform + OpenTofu IaC child module ecosystem in which I'm not aware of anyone who has done that sort of rug pull. I get your point though and that is why I included the "How you should evaluate good OSS" steps towards the end of the article. Hopefully that helps folks pick good packages...

> The Cache API is a web-standard API. We chose to follow it in an attempt to follow standards.

That's perfectly fine, but it doesn't justify the lack of support for non-GET requests though. The Cache API represents the interface but you dictate what you choose how to implement it. In fact, Cloudflare's cache API docs feature some remarks on how Cloudflare chose to implement some details a certain way and chose to not implement at all some parts of Cache API.

https://developers.cloudflare.com/workers/runtime-apis/cache...

Also, the Cache API specification doesn't exclude support for non-GET requests.

https://w3c.github.io/ServiceWorker/#cache-put

If Cloudflare's Cache API implementation suddenly supported POST requests, the only observable behavior change would be that cache.put() would no longer throw an error for requests other than GET. This is hardly an unacceptable change.
