What they need is not so much memory but memory bandwidth.

For training, their models have a certain number of memory needed to store the parameters, and this memory is touched for every example of every iteration. Big models have 10^12 (>1T )parameters, and with typical values of 10^3 examples per batch, and 10^6 number of iteration. They need ~10^21 memory accesses per run. And they want to do multiple runs.

DDR5 RAM bandwidth is 100G/s = 10^11, Graphics RAM (HBM) is 1T/s = 10^12. By buying the wafer they get to choose which types of memory they get.

10^21 / 10^12 = 10^9s = 30 years of memory access (just to update the model weights), you need to also add a factor 10^1-10^3 to account for the memory access needed for the model computation)

But the good news is that it parallelize extremely well. If you parallelize you 1T parameters, 10^3 times, your run time is brought down to 10^6 s = 12 days. But you need 10^3 *10^12 = 10^15 Bytes of RAM by run for weight update and 10^18 for computation (your 120 billions gigabytes is 10^20, so not so far off).

Are all these memory access technically required : No if you use other algorithms, but more compute and memory is better if money is not a problem.

Is it strategically good to deprive your concurrents from access to memory : Very short-sighted yes.

It's a textbook cornering of the computing market to prevent the emergence of local models, because customers won't be able to buy the minimal RAM necessary to run the models locally even just the inferencing part (not the training). Basically a war on people where little Timmy won't be able to get a RAM stick to play computer games at Xmas.

Is it really surprising that the top minds in STEM might not be neuro-typical?

You can't tell me you think Bill Gates, Steve Jobs, Steve Wozniak, Mark Zuckerberg, Peter Thiel, Elon Musk (!), etc., have "normal" brains.

Whether that should count as a disability or a superpower is subjective. ADHD and Autism often present as strengths in one arena, and weaknesses in another. Speaking overly broadly: An aptitude for hard facts and logic, with a difficulty with emotions and social cues.

That's not to say that everyone who presents as such should be given the same accommodations. It's probably being abused. But that doesn't mean they're lying about their brains. It took a doctor to diagnose it. What more would you want to see beyond "a doctors note"?

Your link doesn't say "25%". It's also not an official, up-to-date statistics resource. It's website copy for the office of accessible education

The "1 in 4" number has been there as far back as Wayback Machine has that paged archived (2023): http://web.archive.org/web/20230628165315/https://oae.stanfo...

So it's definitely not a precise statistic, and it's likely out of date.

Taken at face value, this is engineering negligence. I've done industrial design with plastics and 3D printed parts. Regardless of the forming techniques, with plastics you still need to consider properties like minimum melting temperatures, tensile stress, and so forth. Then you must test that rigorously. This is all standard procedure. That information is in the data sheet for the material.

I did a quick search and found that many plastics are governed by ISO 11357 test standard [1]. Some of the plastics I have worked with used this standard.

A spec sheet for that material is here [2].

> However, big caveat - it's self-reported. If you look at how many people get disability benefit it's around 10%.

I don't know about the UK, but in the US, in order to get social security disability, you need to have a documented disability and there's also income limits. If you have a disability, but you manage to find a career despite the disability, you'll lose eligibility for social security disability or at least you'll lose the social security payments. Depending on the disabilities in question, I think it's reasonable that 60% of people with a disability can find work that pays enough that they are no longer eligible for a disability payment and/or they've reached the age where they get a retirement/old age insurance benefit rather than disability.

And this is why (at least for the US) aviation parts have such an onerous paperwork overhead, why a seemingly cheap part like a $.50 bolt balloons to much greater. Granted this aircraft was a UK-equivalent to "experimental" in the US, where you can pretty much do anything to it, I'm of the opinion that doesn't excuse maintenance and adding fly-by-night parts that borders on negligence. Stick to a minimum standard, if not just out of shame of something that could happen.

Why are frequent attendance exemptions granted? I'm totally blind and when I went to college my lack of attendance had nothing to do with the fact that I was blind and everything to do with the fact that I made poor choices like other college students. If I didn't have the mobility skills to get to class then I shouldn't have been granted an exception, I should have been told to get better mobility skills before going to college. I think the only time I asked for an attendance exemption was during finals week. There was a blizzard at the same time as one of my finals and the sidewalks and streets were not plowed. This made it incredibly dangerous for me to go to take the test. I just emailed explaining the situation and took the test the next day.

I worded it in a way flexible to meet everyone's morals. Absent someone trying to performatively live a truly philosophically deontological life every person has some line where they will avail themselves of some available lever to remove some awful situation even if someone else might call it "cheating".

Some recent examples where large segments of the population did this are 1) with medical marijuana cards, which make weed legal to anyone willing to claim to have anxiety or difficulty sleeping, or 2) emotional support animals on airlines, where similarly one can claim anything to get a prescription that, if travelling with a pet, opts them out of the sometimes-fatal always-unpleasant cargo hold travel.

Plenty of people would call either of these cheating, but kind of like how "language is usage", so are morals in a society. If everyone is doing something that is available but "cheating", that society deems the result for people sufficiently valuable.

I wonder if just including the aluminum tube that was effectively acting as a heat break would have been enough...

Really it seems like a problem of not understanding the environment, and testing (with margins) your replacement in it... 3D printing seems nearly entirely unrelated apart from enabling people to make parts.

An injection molded part, for a close more traditional analogue, would presumably have failed the same way here.

Also the glass transition temperature reported in the report is suspiciously low for ABS and the only source on the material is the owner saying the person they bought it from said... I wonder if it was just outright made out of the wrong material by accident.

Price spikes like we are seeing reflect tremendous pent-up/increased demand.

Any price increase reduces purchases by many customers. This tends to keep prices stable. With only small changes in price relative to regular changes in demand.

Yet prices have gone way up.

Which means that many people and businesses are cancelling, delaying, or scaling back their RAM purchases. And yet new demand is incredibly high.

To get prices down, supply would have to grow tremendously. Enough to soak up even more purchases from the very motivated, and to cover all the purchasers that have currently pulled back.

The combo effectively enshittified swaths of the Internet, which now is full of robo-pamphleteers acting with anonymous impunity, in ways they never would if sitting face-to-face.

I love the Internet but it normalizes bad behavior and to the extent the CJEU was tracking toward a new and more stringent standard, well earned by the Internet and its trolls.

Sigh. "..that personal data processed must be accurate and, where necessary, kept up to date. "

How do they think a hosting provider can check if personal data is accurate? Maybe if privacy didn't exist and everybody could be scrutinized.. but the ruling refers to the GDPR to justify this, and the GDPR is about _protecting_ privacy. So, what is it?

And for everything else.. is the material sensitive or not? How can anyone know, in advance?

I suggest every web site host simply forward all and every input to an EU Court address, and let them handle it. They're the ones suggesting that hosts should make sure that personal data on someone is "accurate", they're the ones demanding that the data should not be "sensitive", so they can as well be responsible for vetting the data.

But they're all crazy anyway, as they demand that a website must block anyone from copying the content.. so how, at the same time, can you even have a website? A website which people can watch?

If the ruling was about collecting data which isn't for displaying, i.e. what a net shop does (address, credit card number), then this would be understandable. But provisions for that already exists, instead they use this (GDPR) as a tool to extend this to user-created content. It's not limited to ads, and ads do need something done. Something totally different from this.

Your comment explains why students would like to receive these accommodations (it gives them a competitive edge), but does nothing to explain why this is logical or beneficial.

If as you say the number of available positions is constrained, this system does nothing to increase the supply of those positions. It also does nothing increase the likelihood that those positions are allocated to those with the greatest material need. This is Stanford; I am sure many of the disabled students at Stanford are in the 1%.

Shipping updates almost weekly is the opposite of what I want for a complex, mission-critical distributed system. Building a production-ready S3 replacement requires careful, deliberate and rigorous engineering work (which is what Garage is doing[1]).

It's not clear if RustFS is even implementing a proper distributed consensus mechanism. Erasure Coding with quorum replication alone is not enough for partition tolerance. I can't find anything in their docs.

I had a friend in high school who was able to take untimed tests. I later heard a teacher griping, because they didn't think my friend needed them. (I agree.)

My friend had a very good life, until he took a job that really clashed with his, uhm, tendency to be a perfectionist. When we caught up (because we hadn't spoken in a few years,) it was clear he didn't have much insight into how his perfectionism worked against him in the job. (It was a job where quantity was more important than perfection.)

What would have helped my friend more? Not the diagnosis that he needed untimed tests. Instead, counseling where he understood his difference, how to make best use of it, and when he needed to let go and not be a perfectionist.

Count me in as another one with a longstanding mostly dream project aiming for human enjoyable notation grammar.

For me it was coming from tracker notation (buzz), where i was wildly underwhelmed by all that whitespace for timing (well, empty cells for timing) and the lack of parameterizable macros. A seriously underexplored field, perhaps because almost everybody who ever started got pulled in by the lure of textually defined synthesis.

> 15-20% of the world is estimated to have a disability. So Stanford population is high, but approximately double the average of a random global population sample.

Stanford is not a random sample of the global population. Most notably, Stanford undergraduates are young, primarily between 18-24[1]. 8.7% of people in the US from ages 18-29 have a disability [2].

Why is this, I wonder? Aren't the models trained on about the same blob of huggingface web scrapes anyway? Does one tool do a better job of pre-parsing the web data, or pre-parsing the prompts, or enhancing the prompts? Or a better sequence of self-repair in an agent-like conversation? Or maybe more precision in the weights and a more expensive model?

1 in 4 is 25%

it's on their website. Along with all the other details. where is 38% coming from that is a better source than Stanford's own website. At a minumum the article should have said where they got that number and why it disagrees with Stanford's own number.

And again, it includes every possible kind of accommodation under the sun. Which is totally fine and not an issue of any kind.

> In general, being good at academics require you to think carefully not quickly.

Yes, but to go even further: timed tests often test, in part, your ability to handwrite quickly rather than slowly. There is great variation in handwriting speed — I saw it as a student and as a professor — and in classrooms, we should no more be testing students for handwriting speed than we should be testing them on athletic ability.

In general, timed tests that involve a lot of handwriting are appalling. We use them because they make classroom management easier, not because they are justifiable pedagogy.

This work explores whether large language models can replicate the qualitative reasoning processes used by investment committees, instead of relying on numerical optimizers.

The first component is a correlation-aware selection method that repurposes a hierarchical clustering dendrogram as a tournament bracket. At each internal node, the LLM allocates selection slots between clusters and performs structured eliminations within correlation regimes.

The second component is a portfolio evolution loop that contains no objective function, expected returns, covariance matrices, or solvers. Instead, the model compares variants using a qualitative rubric (business quality, durability, thematic alignment, drawdown resilience, diversification) and accepts improvements through iterative reasoning.

Both mechanisms are fully text-explainable: every elimination, selection, and mutation is auditable.

Sure - once you have dozens of engineers and 5 years under your belt you'll be good to go!

This will get you started: https://youtu.be/B2482h_TNwg

Keep in mind that every wafer makes multiple trips around the fab, and on each trip it visits multiple machines. Broadly, one trip lays down one layer, and you may need 80-100 layers (although I guess DRAM will be fewer). Each layer must be aligned to nanometer precision with previous layers, otherwise the wafer is junk.

Then as others have said, once you finish the wafer, you still need to slice it, test the dies, and then package them.

Plus all the other stuff....

You'll need billions in investment, not millions - good luck!

>Entitlements cost quite a bit of money to fulfill.

Entitlements are funded by separate (FICA) taxes which form a significant portion of all federal income, they are called entitlements for that specific reason.

> Quibbling over terminology doesn't erase the point - that a significant portion of the Federal budget is money virtually everyone agrees shouldn't be touched much.

Quibbling over quibbling without mentioning the separate account for FICA/Social Security taxes is a sure sign of manipulation. As is not mentioning that the top 10% are exempt from the tax after a minuscule for them amount.

Oh, and guess what - realized capital gains are not subject to Social Security tax - that's primarily how rich incomes are made. Then, unrealized capital gains aren't taxed at all - that's how wealth and privilege are accumulated.

All this is happening virtually without opposition due to rich-funded bots manipulating any internet chatter about it. Is it then surprising that manipulation has reached a level of audacity that hypes solving the US fiscal problems at the expense of grandma's entitlements?

This paper reports an unexpected pattern that appeared repeatedly during evolutionary search over technical indicator architectures. Across unrelated markets (crypto, FX, index futures, equities), the search process converged toward similar structural motifs.

These motifs included multi-scale momentum, entropy-based filtering, volatility-adaptive scaling, and regime gating. They reappeared independently across runs, suggesting that certain indicator structures may function as “market invariants” under diverse microstructures.

The system does not use prior knowledge of finance; it only evaluates candidate architectures by out-of-sample performance and stability. The repeated convergence raises questions about whether modern markets impose structural constraints that shape successful technical signals.

Hmmm, maybe use a different OS? I would never dream of using Windows to get any type of work done myself and there are many others like me. There certainly are choices. If you prefer to stay, MCP services can be configured to use local models, and people are doing so on Windows as well (and definitely with MacOS and Linux). From an OS instrumentation perspective, I think MacOS is probably the most mature -- Apple has acknowledged MCP and intends a hybrid approach defaulting to their own in house, on device, models, but by embracing MCP appears to be allowing local model access.

This article mirrors exactly how I’ve been feeling. I'm tired of being attacked for using these tools. AI doesn’t diminish understanding—it forces us to admit that “full understanding” was always partial. Working with AI forces clearer thinking about boundaries, contracts, and system behavior. It makes engineering more explicit, more honest, and ultimately more rigorous, not less. This is the craft of software development evolving, not disappearing.

>> You've made a much larger claim (80-90%) than the article. That is interesting. And anedata, unless you have solid evidence of your opinion.

Firstly No evidence provided and none needed as an unscientific anecdata supporting my personal shock.

- Many of these accomodations for SATs are done in high school and then it isnt required anymore, so naturally people dont ask once they have already gotten into college. The SAT used to be a singular choke point for top schools, and becomes irrelevant immediately after.

- I was speaking about SAT and the article was talking about accomodations needed for college housing and other things

1. I provided an anecdote based on friends' personal statements, not statistics based on school, you should trust the school's stats, but i'd really like to see the stats from The College Board on SAT scores, with a WHERE clause on only scores/accomodations for students going to top schools

2. I provided an anecdote that may well be wildly inaccurate being n=1

3. I entered to college in 1996, we're 29yrs off from my experience and the article

4. As I said above, accomodations in college != accomodations for SAT

> 100.000 writes per bit

per cell*

Also, that SSD example is wildly untrue. Especially with the context of available capacity at the time. You CAN get modern SSD's with mind boggling write endurance per cell, AND has multides more cells, resulting in vastly more durable media than what was available pre 2015. The one caveat there to modern stuff being better than older stuff is Optane (the enterprise stuff like the 905P or P5800X, not that memory and SSD combo shitshow that Intel was shoveling out the consumer door). We still haven't reached parity with the 3DXpoint stuff, and it's a damn shame Intel hurt itself in it's confusion and cancelled that, because boy would they and Micron be printing money hand over fist right now if they were still making them. Still, Point being: Not everything is a TLC/QLC 0.3DWPD disposable drive like has become standard in the consumer space. If you want write endurance, capacity, and/or performance, you have more and better options today than ever before (Optane/3DXPoint excepted).

Regarding CPU's, they still follow that durability pattern if you unfuck what Intel and AMD are doing with boosting behavior and limit them to perform with the margins that they used to "back in the day". This is more of a problem on the consumer side (Core/Ryzen) than the enterprise side (Epyc/Xeon). It's also part of why the OC market is dying (save for maybe the XOC market that is having fun with LN2), those CPU's (especially consumer ones) come from the factory with much less margin for pushing things, because they're already close to their limit without exceedingly robust cooling.

I have no idea what the relative durability of RAM is tbh, it's been pretty bulletproof in my experience over the years, or at least bulletproof enough for my usecases that I haven't really noticed a difference. Notable exception is what I see in GPU's, but that is largely heat-death related and often a result of poor QA by the AIB that made it (eg, thermal pads not making contact with the GDDR modules).
