If my tone came off as confrontational, that was not my intent. But I do intend to say this: It seems to me that _you_ are ascribing malice to my comment. I was offering a (admittedly very strong) counterpoint to OP, which was that I do find a ton of value with claude code. It really has been a game changer to our productivity.

Although, based on your response, I did go back to read their original post to see if I missed some nuance, and I did.

They were talking about using the alternate model WITH Claude Code. I didn't know that was an option, and would definitely be willing to try things out (as we all are experimenting a lot these days).

At the end of the day, it's less about Claude Code, but that form of coding. It's not perfect by any stretch, but it has changed my ability to ship features in HUGE ways.

Update: This is not a comment on the technical strength of z.ai, but I would have concerns about it being based in China. This isn't insurmountable, like with companies like Zoom that are Chinese owned but guarantee US-based servers/data/staff, etc. But I suspect that will hold many back. Again, everyone's a grownup here, and I'm sure z.ai already has a plan to address that "weakness" in their value.

Breaking up a monopoly must follow sustainable business lines. The court’s early idea of forcing Google to spin off Chrome risked crippling the product and disrupting the market without restoring competition. The remedy was later scaled back, leaving Google with little more than a slap on the wrist. By contrast, the AT&T and Microsoft cases succeeded because they targeted natural, profitable divisions that could stand alone. Addressing areas like Azure or MacBooks, which are not monopolies, does nothing to reduce monopoly power. A more effective remedy in Google’s case would have been dividing its multiple monopolies, rather than divesting loss-leading but essential units. Profitability alone does not define a monopoly, but once one is identified, ensuring that each division can operate as a viable business is crucial.

Adding to the swath of anecdotes here so wiser policymakers and teachers than myself have more perspectives to draw from in addressing the ongoing learning crisis.

I was in High School for the first full class of the new millennium (2000-2004). Being gifted at the time (now we know I just had OCD and hyperfocus), I’m cruising through on Honor Roll and knocking even difficult content out of the park. It’s to the point that I’m sleeping through English with a perfect GPA and have been politely asked by my Social Studies teacher to stop answering questions (to give other students a chance to learn) and just work on my homework in his class while he teaches. Everyone is super chill, happy to teach, and has no compunction failing students who don’t grasp the material and fail to seek help.

January 8, 2002. Social studies is my last class of the day. The teacher storms in, angry, and flips his desk in rage.

Alright, you have our collective attention.

He points furtively at the class while facing the chalkboard before turning around. “Congratulations, you’re the last group of students to get a decent education. Starting next semester, No Child Left Behind means we’ll be teaching to tests and not covering the material, and every single class after you is going to be dumber as a result. You better pay attention, because this is the last good world history class you’ll likely ever have.”

I could not hope to appreciate his wisdom at that moment, but in the years since? Dude was 100% correct. I learned about context and nuance to discuss on essay exams; my siblings who came after me learned rote dates and events for a standardized test. The irony is that they have superior college credentials (MS and BA) than I do (AS), but all three of us are fairly even in footing in our overall intelligence, seeking of new knowledge and data, and ability to teach others. I can anecdotally credit my superior education pre-NCLB for preparing me to succeed in the real world compared to younger peers who have required far more (expensive) education to get to the same point. Introducing KPIs alone won’t fix the problem, it will require rekindling a passion for learning in the hearts of students, teachers, and parents alike to restore our basic comprehension scores.

And before people ask: yes, we too had the dreaded issues of defunding everything to fund the football team. My school closed auto, metal, and eventually wood shop classes to create three more weight training rooms for the sports teams, and cancelled HomeEc in lieu of letting bankers do an hour lecture on credit cards to Seniors.

Nothing special about YouTube other than the interface being about as offensive as possible. Rumble is light-years better in terms of speed and has an instant CSS based dark theme unlike the monolyth. I'm concerned many users that continue to use any sort of modified version of YouTube are going to eventually have their Google account sniffed out and banned. Many creators have shifted over to publishing to multiple platforms at once so that platforms like Rumble and Odysee don't seem as siloed with certain types of content. Rumble is sharp and stays out of the way, and that matters, as unlike the YouTube experience on iOS, you can still get a video to play audio only in background; it makes YouTube feel like an ad machine cesspool.

> Looks good alright? Or does it? How do you know? You can’t if you don’t have sufficient background knowledge … If you can’t produce a comprehensive answer with confidence and on the whim the second you read the question, you don’t have the sufficient background knowledge.

> “I just ask ChatGPT for that, too!”, the AI generation might ask. Ok, and then what? How can you assess the answers … you are taking on an impossible task, because you can’t use enough of your brain for your cognitive operations.

So it’s Zeno’s paradox of knowing stuff?

It can’t be impossible to know things, you’ve just got to decide when you know enough to get going on. Otherwise you’re mired in analysis paralysis and you never get anything done.

I do agree that deep knowledge of the foundations a subject - particularly a skilled practice or craft - is a path to proficiency and certainly a requirement for mastery. But there are plenty of times when you can get away with ‘just reading the documentation’ and doing as instructed.

You do not first need to invent the universe in order to begin exercising, you can just start talking a 20 minute walk after lunch.

Well it doesn't help that the media, even when it doesn't lie, often simply refuses to report on various issues depending on the whims of producers.

I'm an older millennial, probably one of the last generations who was formally taught that organizations like the New York Times and CNN were authoritative, bibliography-worthy sources of information due to their reputation and standards. I haven't cared much about what either outlet has produced in years. For every good investigative piece there's a mountain of obvious propaganda or refusal to cover topics they find uncomfortable with any objectivity.

The signal to noise ratio is so low, why pay attention? There's a lot of bad takes on twitter and non-mainstream media (to put it mildly) but it at least makes me aware of more things.

TL;DR: «Only “necessary traffic” is allowed in Pontevedra: vehicles used for emergency and public safety, public services (including garbage and water trucks, etc.), transportation of people with reduced mobility, and accessing private garages are permitted 24/7. However, loading and unloading for commercial supplies, home delivery, transporting bulky objects, and house moving and related activities, are permitted only during certain hours.»

> The reduced engagement with the material reduces the emotional weight of the whole line of action. You mind is an engine that is fuelled by emotion. Without any emotion, you don’t think. Rather, you try to imitate thinking efficiently.

This doesn't sound true and they don't seem to offer any support for the claim.

There's a whole host of emotion-driven cognitive biases, where an effective counter is to reduce the emotional weight of the whole line of action.

Of course, to their credit, it's only by remembering those biases that I could see their error

- Paris' subway doesn't have elevators, impossible with a stroller.

- Buses are crowded, very slow, and being blocked for >1h because of protests or roadworks with a sick newborn is a rather unpleasant experience. I did it already. And in general, public transportation in Paris has degraded a lot. Who wants to explain to his 3-year-old son what this fine gentleman is doing while heating crack in the back of the train car?

I've been working with functional programming languages for the most part of my career now. Mostly Elixir and Clojure, but some OCaml/Haskell too. I believe after FP "clicks", there is no going back. Everything else feels just so unnecessarily complex.

My favorite is still Clojure by miles ahead, besides it being a functional language, its data-oriented approach to writing programs is completely different from anything else I've ever seen. I currently work with Elixir, and there isn't a day that goes by without me thinking "gosh, this would be so much simpler to solve in Clojure".

The front-to-back symmetry is interesting. It may cause some confusion for other drivers, in some limited circumstances, when they can't tell which way the vehicle is facing.

It appears, based on my study of the footage on https://www.youtube.com/watch?v=lIRW8bfy4kE, that it could possibly switch which side is the front and the back by just changing the color of the lights. With RGB LEDs that would be pretty easy to do. But my question is, when would that be useful?

It would be neat that it could pull into a driveway and then leave in "reverse", but that doesn't seem like it'd come up that often for a robotaxi.

The back wheels look like they can steer. That's useful for parking in tight spaces.

Is the idea cars start a fact or a concept? Is the certainty I remember how this particular car starts a fact?

Once we begin to disengage from the arbitrariness inherent in arbitrary metaphors, and rely on what actually generates memories (action-neural-spatial-syntax), we can study what's really happening in the allocortex's distribution of cues between sense/emotion into memory.

Until then we will simply be trapped in falsely segregated ideas of episodic/semantic.

But 40,000+ Americans die in their cars (and run over by others' cars) every year. No subway caveat is ever going to beat that. And at least it's obvious that subways going missing is a _very_ solvable problem. We've completely given up on making driving safer.

EDIT: Sorry, re-read the context, and I think you were countering my claim that a subway will always get you there on time? Yeah. You're right. Subways can absolutely be delayed, go missing, stop running, go on strike, etc. Sorry for going off the "rails" there. :D

It is not clear on which core the successor of Neoverse V3 (the server version of Cortex-X4, which is used in the latest Graviton) will be based.

Arm C1-Ultra is the successor of Cortex-X925. C1-Ultra has great improvements in single-thread performance, but Cortex-X925 had very poor performance per die area, which made it totally unsuitable for server CPUs. Arm has not said anything about the performance per area of C1-Ultra, so I assume that it continues to be poor.

Arm C1-Pro is the successor of Cortex-A725. Arm has made server versions of the Cortex-A7xx, but Amazon did not like them for Gravitons, for being too weak.

Therefore only Arm C1-Premium could have a server derivative that would become the successor of Neoverse V3 for a future Graviton.

For now, the technical manual of C1-Premium is very sparse. Only when the optimization guide for C1-Premium will be published, showing its microarchitecture, we will know whether it is a worthy replacement for Cortex-X4/Neoverse V3, which had the best performance per die area among the previous Arm CPU cores.

The person who wrote that site spent quite a lot of time writing, yet unfortunately little reading. Heritability is, by definition, the degree of variation in a trait, within a population, due to genetic variation. The heritability of an accent is zero.

One clever way this is measured is twin studies, which also are not what most people, particularly those who prefer to write more than read, think. You don't search for twins separated at birth, but instead compare the differences in a trait between identical and non-identical twins. If the variation is greater, then the trait is generally significantly heritable. So for example - height would be an obvious one. By contrast the variation in accent between identical and non-identical twins would be zero.

It can be, but in the situation we're discussing not really. The actress is free to decline the offer.

Here's a thought experiment, imagine the offer is way worse. Imagine it's like "I'll mow your lawn if you have sex with me" is that rape? If you really don't want the sex you just say no and that's that, you mow the lawn yourself. I don't think most people would consider that person a rapist.

The difference here is that a better offer is harder to refuse. That does change the situation in a meaningful way but it's still entirely voluntary.

Because the USA is one country and Europe is a collection of vastly different countries.

You would likely agree that the USA and Mexico are incomparable and its sort of the same, though the EU evens some things out: its much less far reaching than a federal government.

That said: happy to compare the best case US public transport to the Nordics. Literally anywhere in the Nordics to anywhere in the US.

Convenient access is a huge deal. Students are at school every day whereas with public libraries they are limited to their parents' schedule. I know I was able to read nearly twice as much fiction as a teen because I could checkout a new book the same day I finished the previous one rather than waiting a week or so until we could go to the public library. Having the library is also useful for integrating into classes, for example my English classes would alternate between assigned books and reading a book of your choice, and we would make trips to the library during class time to be taught how to use libraries for research. Lastly, in rural areas the school libraries are often the only library.

We will eventually add the SERIALIZABLE isolation level to OrioleDB, but right now that's not our highest priority. Let me explain why. At first, SSI (serializable snapshot isolation) in PostgreSQL comes with significant shortcomings, including.

1) Overhead. SSI implies a heavyweight lock on any involved index page or heap tuple (even for reads). The overhead of SSI was initially measured at ~10%, but nowadays, scalability has gone much farther. These many HW-locks could slow down in multiple times a typical workload on a multicore machine.

2) SSI needs the user to be able to repeat any transaction due to serialization failure. Even a read-only transaction needs to be DEFERRABLE or might be aborted due to serialization failure (it might "saw impossible things" and needs a retry).

In contrast, typically it's not hard to resolve the concurrency problems of writing transactions using explicit row-level and advisory locks, while REPEATABLE READ is enough for reporting. Frankly speaking, during my whole career, I didn't see a single case where SERIALIZABLE isolation level was justified.

That’s my read. Even if there was some other logistical barrier, updating a bunch of external dependencies as most people do it unavoidably involves pre-trusting code you’ve never seen. I don’t think there’s any way around that, and given that, I don’t think there’s a purely technical solution. This requires having more vetting within package manager, but that’s not an easy lift.

Have agreed in previous comments that this was subjective (as a family but also as a driver) experience.

Maybe one thing that amplified the effect was the high expectations we had for those highways, and maybe that's what made it more shocking for us.

Again, I consider myself a 'decently skilled' driver, having driven in many countries over the course of the years, and easily adapting to driving styles (US/Italy/France/Iran/UK/India/etc). Some of these styles are indeed chaotic, but they (generally) operate at slower speed, which allow for corrections and precautions. The thing that threw us off is the combination I have mentioned before:

> [...] the speed that those roads allow. The style was quite aggressive, very fast in every lane, loads of overtakes (car constantly zig-zagging), people coming from the back _FAST_ and staying there, people switching lanes immediately after signalling rather than giving some time for people to notice. Overall, that combination made for a very stressful experience which we have agreed (as family) not to repeat in the future.

Yes, it’s extremely rare to be stuck with a broken/wrong/missing item as a buyer on eBay. Selling is quite risky in some ways because eBay will nearly always side with a buyer. Every missing or broken thing I have purchased has been refunded or replaced. On the other hand, 3 things I have sold were claimed to not arrive. The only case where eBay decided in my favor was when the buyer had signed for the package in a literal USPS office :)

> What I hold on to are the core concepts that allow me to hit the ground running when I have to interact with the subject-matter again.

Exactly. And those also come with doing the thing, or watching the thing being done, or reading about the thing, or thinking about the thing. You often don't have to actively try to kastle / cram / grok / etc the information to remember it. Just being exposed to it will make you remember some of it. Knowing where to get more accurate info is often a greater skill / benefit than knowing the details yourself. Especially in fields where knowing all the details yourself is almost impossible.

Weak article.

It's funny you say that, because the Tyrant of Jupiter series was written by Piers Anthony, whom I understand to be considered nowadays as problematic and misogynistic. The misogyny shows through, especially in a scene where the main male protagonist is making back room military deals with a woman, and the method of negotiation is, to be rather explicit, a martial grappling match, in the nude, in a zero-G bubble, where the protagonist wins the rounds by physically subduing his woman counterpart and achieving PIV penetration before they separate and go again.

Like I said, I can't recommend that series now that I have a more mature perspective. But I can't imagine that a book written by a misogynistic author with explicit themes of female submission to male authority obtained by use or threats of physical and sexual violence would be particularly appealing to women in general, let alone women who have grown up in a culture that has in recent times had much more acknowledgement of such things, e.g. MeToo, more widespread conversations about toxic masculinity, the oppression of women by physical force and the male-dominated hierarchy that projects that force.

If you disagree and think that young women (and enby people) would find such books appealing though, I'm interested to hear why.

Exactly. I'm not able to memorize multiplication tables or even listen to math lectures - I can't hold more than one or two numbers in my head before they start disappearing. However, I am capable of learning and using math to an advanced level, at least temporarily.

How? The way I think of numbers is actually quite similar to what is currently known as "new math". It's not taught well because almost no teacher was raised with it (and thus lack the ability to think in new math "natively"), but it is based on something real.

Everybody loves public transit until they get panhandled for the jillionth time, or they witness (or experience) violence, or some other anti-social behavior sours the whole thing.

These are not issues with public transit. These are issues with municipalities that don't invest in their citizens.

For one example, public transit connects people to jobs. Some people in nicer areas with good jobs fight against public transit because they don't want the working class to have easy access to their neighborhood. So, again, the issue isn't public transit, it's people who don't want to share their municipality's resources. New York today has free kindergarten, universal school lunches and the excelsior scholarship program. Thanks to investments like this, we see crime in NY today is lower than even Giuliani's tenure as mayor...

It’s an LLM that has been trained and prompted to make users believe that the model is using logical reasoning to arrive at its output, when it is in fact still predicting the possible next output tokens, just like any other LLM.

There may be additional feedback loops, but fundamentally, that is what it is doing. Sure, it will show you what steps it takes to arrive at a conclusion, but it is just predicting the steps, the conclusion and the potential validity of the aforementioned based on its training data, not actually evaluating the logic or the truthiness of the output.

If you don’t believe me, ask your ”reasoning” LLM this question: What’s the name of the paternal great-great-grandfather of the son of Jacob’s son’s son’s son?

Historically, labor unions opposed child labor for reasons that a) they should be in school learning things and b) they work really cheaply since they're unskilled. Unions in the 1800s were pretty open about why they opposed child labor, and they always mentioned the corrosive effect of an underclass of unskilled labor. So yeah... people might not think about it much now. But if you repealed child labor laws, I'm pretty sure the unions would be trying to fund high schools EXPLICITLY so they could shape the structure of labor participation by cohort.

I am not familiar with this particular product but generally if you run on say AWS you either need to account for the greatly increased disk latency due to EBS being network storage or build provisions for local storage that is not necessarily unlimited, it is unclear what kind of disk controller it is attached to, etc. It could also mean optimizing for the AWS-specific CPU architecture. Or it could mean using S3 as storage which has yet different durability and consistency semantics compared to other storage systems. It might also mean optimizing for pricing of a given cloud provider in some way.
