I was pretty disappointed to learn that the METR metric isn't actually evaluating a model's ability to complete long duration tasks. They're using the estimated time a human would take on a given task. But it did explain my increasing bafflement at how the METR line keeps steadily going up despite my personal experience coding daily with LLMs where they still frequently struggle to work independently for 10 minutes without veering off task after hitting a minor roadblock.

On a diverse set of multi-step software and reasoning tasks, we record the time needed to complete the task for humans with appropriate expertise. We find that the time taken by human experts is strongly predictive of model success on a given task: current models have almost 100% success rate on tasks taking humans less than 4 minutes, but succeed <10% of the time on tasks taking more than around 4 hours. This allows us to characterize the abilities of a given model by “the length (for humans) of tasks that the model can successfully complete with x% probability”. For each model, we can fit a logistic curve to predict model success probability using human task length. After fixing a success probability, we can then convert each model’s predicted success curve into a time duration, by looking at the length of task where the predicted success curve intersects with that probability.

Together with PDD/NOS (which is an entire category on its own, because you also could be diagnosed with this if you "just" have brain damage, leading to autistic like symptoms), Childhood disintegrative disorder, and Rett syndrome.

But to simplify diagnosis they swept it all up and since DSM V was released all those things are now under the ASD (Autism Spectrum Disorder) umbrella

This doesn’t read as all or nothing to me. If you’re communicating with somebody who doesn’t understand the acronyms (or even someone who might not understand the acronyms), and you still do it, then yeah, it’s a signal that there may be something underneath the surface there.

Obviously if we’re all familiar then go right ahead and save us all some time, but it’s worth considering how something as benign as using acronyms might subtly exclude people from the conversation for no good reason. The value of the article is in recognising this.

Afaik most LLM datasets use FastText or something similar to detect the language of the data and if it's spam, and some additional small language models to detect if text is "educational" or desirable in some other way. Often text is filtered in instead of filtered out, so anything unusual like this probably won't pass the filter, you don't need to detect it explicitly.

'And the director himself declined'

An anecdotal personal story as it aligns with this exact statement although no one got killed but data breaches certainly occurred.

Many years ago now I was propositioned to be on the board of a financial technology company and they spared no expense in literally rolling out the red carpet for my arrival. I found it all very laughable being solely focused on business and the technical details as I was not being fooled by all the schmoozing. After hearing all the unrealistic business objectives and the promise of having the Philadelphia Flyers involved I then asked to meet the technology team that built the product to see a demo. They bring in one young guy who built it all, the executives are still present mind you, and they allow me to ask any and all questions about the platform that nearly no one in management comprehended. After seeing the demo which involved several blatant security issues I asked only one more question of the sole developer: "Would you put your financial information into this system?"

He provided his answer in front of the companies executive board and I can still see their reactions to this very day. I then stood up and thanked everyone for opportunity and left.

What's going on is that we've spent a few solid decades absolutely destroying normal human relationships, mostly because it's profitable to do so, and the people running the show have displayed no signs of stopping. Meanwhile, the rest of society is either unwilling or unable (or both) to do anything to reverse course. There is truly no other outcome, and it will not change unless and until regular people decide that enough is enough.

I'd tell you exactly what we need to do, but it is at odds with the interests of capital, so I guess keep showing up to work and smiling through that hour-long standup. You still have a mortgage to pay.

¯\_(ツ)_/¯ I'd like to lean into that "YMMV" in my post, I'm coming from low level C that interacts with hardware, can't really speak to higher-level C++.

Some things in Rust just don't translate to the way you'd do them in C - e.x. using different types to say if a GPIO pin is input or output adds a ton of boiler plate, but lets the compiler assure you don't mistakenly try and use a pin configured as an input for output.

In general, the whole zero sized types paradigm in Rust leads to way more lines of code to accomplish the same thing (it all ends up compiled out in the end though).

For embedded, I'll stand by what I said: it takes longer to write idiomatic Rust but you are more likely to get functionally correct code in the end.

A little chemistry:

CH4 + 2 O2 -> CO2 + 2 H2O - 890kJ/mol C + O2 -> CO2 - 393kJ/mol

The relevance of those equations are that CH4 is methane, the principle component of natural gas, C is pure carbon, the principle component of coal and the USA has been transitioning it's energy production from coal to natural gas.

The above equations say if you produce the same amount of electricity with natural has, your CO2 emissions halve. That is the driver of the reduction you point to. It is nice to see, but halve is the best that can happen. Meanwhile if China's continues down it's current path, their CO2 emissions for electricity production will drop to 0.

According to the EIA, the USA has about 18 years of reserves of natural gas at current production rates [0]. The USA has about 70 years of reserves of coal, so this transition to using natural gas is temporary. After about 100 years the USA will run out of both. If you want to see what that looks like, look at the UK.

Really? Hmm... where in the HTTP spec does it allow for returning an arbitrary subset of any specific request, rather than the whole thing? And where does it ensure all the results are keyed by id so that you can actually build and update a sensible cache around all of it rather than the mess that totally free-form HTTP responses lead to? Oh weird HTTP doesn't have any of that stuff? Maybe we should make a new spec, something which does allow for these patterns and behaviors? And it might be confusing if we use the exact same name as HTTP, since the usage patterns are different and it enables new abilities. If only we could think of such a name...

No one I've seen does without at least battery backup/conditioning/etc. Some may have less than 100% redundancy on generators, but that's mainly because some of them are running with e.g. a 200MW grid feed and 20x10MW gensets and ALSO running about 10-15 of the "backup" gensets as prime power. It's possible corners are cut during commissioning (like they use modular structures during buildout of the tilt-up ISO 5 permanent structure), but substanially no one would do this as their long-term design goal.

It's possible I'm talking out of my ass and totally wrong because I'm basing this on principles, not benchmarking, but I'm pretty sure the problem is more etcd itself than boltdb. Specifically, the Raft protocol requires that the cluster leader's log has to be replicated to a quorum of voting members, who need to write to disk, including a flush, and then respond to the leader, before a write is considered committed. That's floor(n/2) + 1 disk flushes and twice as many network roundtrips to write any value. When your control plane has to span multiple data centers because the electricity cost of the cluster is too large for a single building to handle, it's hard for that not to become a bottleneck. Other limitations include the 8GiB disk limit another comment mentions and etcd's hard-coded 1.5 MiB request size limit that prevents you from writing large object collections in a single bundle.

etcd is fine for what it is, but that's a system meant to be reliable and simple to implement. Those are important qualities, but it wasn't built for scale or for speed. Ironically, etcd recommends 5 as the ideal number of cluster members and 7 as a maximum based on Google's findings from running chubby, that between-member latency gets too big otherwise. With 5, that means you can't ever store more than 40GiB of data. I have no idea what a typical ratio of cluster nodes to total data is, but that only gives you about 307MiB per node for 130,000 nodes, which doesn't seem like very much.

There are other options. k3s made kine which acts as a shim intercepting the etcd API calls made by the apiserver and translating it into calls to some other dbms. Originally, this was to make a really small Kubernetes that used an embedded sqlite as its datastore, but you could do the same thing for any arbitrary backend by just changing one side of the shim.

My impression is that there is a lot more going on than just the facts provided by both sides. Core technologies managed to get Katie Berry to step away from the project[1] and that's extremely significant to me. Her tireless dedication to keeping Pebble alive (and get it open sourced) is how any of this is possible. For her to just up and leave now tells me that Eric and Core are not being as magnanimous and friendly to community as these blogs posts and actions might suggest.

Select the verts, drag them in the right direction. A little pane pops up saying you moved them by .78 mm. Change it to .5mm and you're done.

If you're using boolean operations to make the holes just move the hole-cutter. Same method.

There was a considerable debate on the ergonomics of terminal colors, where the pseudoscience said green and amber were the best... and white wasn’t very good. I’m not sure what the truth was. Adding a couple of inches to the 12-inch screens of the time would have made a bigger difference in eye fatigue than phosphor color. That said, there was something magical about glowing phosphor...

"Free" health care paid for by people richer than me? There aren't enough of them to pay for all us slackers. "Free" health care pair for by people poorer than me? That's actually probably what is going to happen if I retire early.

I vote no.

If a majority votes yes, does that absolve me of guilt that poor people are paying for my early retirement?

Tested this today for implementing a new low-frequency RFID protocol to Flipper Zero codebase based on a Proxmark3 implementation. Was able to do it in 2 hours with giving a raw psk recording alongside of it and some troubleshooting. This is the kind of task the last generation of frontier models was incapable of doing. Super stoked to use this :)

And they killed Supermaven.

I've actually been working on porting the tab completion from Cursor to Zed, and eventually IntelliJ, for fun

It shows exactly why their tab completion is so much better than everyone else's though: it's practically a state machine that's getting updated with diffs on every change and every file you're working with.

Actually, this seems to be mostly a spike in retail prices, not wholesale DRAM contracts that are only up 60% or so in the past few months according to Samsung. So we should most likely place at least some fraction of the blame on our fellow consumers for overreacting to the news and hoarding RAM at overinflated prices. DRAM sticks are the new toilet paper.

Gemini is a lot more bang for the buck. It's not just cheaper per token, but with the subscription, you also get e.g. a lot more Deep Research calls (IIRC it's something like 20 per day) compared to Anthropic offerings.

Also, Gemini has that huge context window, which depending on the task can be a big boon.
by localhost | 2025-11-24 22:06:18+00:00
Totally agree with this. I have seen many cases where a dumber model gets trapped in a local minima and burns a ton of tokens to escape from it (sometimes unsuccessfully). In a toy example (30 minute agentic coding session - create a markdown -> html compiler using a subset of commonmark test suite to hill climb on), dumber models would cost $18 (at retail token prices) to complete the task. Smarter models would see the trap and take only $3 to complete the task. YMMV.

Much better to look at cost per task - and good to see some benchmarks reporting this now.

The cost of tokens in the docs is pretty much a worthless metric for these models. Only way to go is to plug it in and test it. My experience is that Claude is an expert at wasting tokens on nonsense. Easily 5x up on output tokens comparing to ChatGPT and then consider that Claude waste about 2-3x of tokens more by default.

They do take a severity into account, they look at the amount of support which is required by the person which has been diagnosed.

Which according to DSM V either can be level 1 ("Requiring support"), level 2 ("Requiring substantial support") or level 3 ("Requiring very substantial support").

No, not a truck.

But if you and a pal own a small business, maybe you employ fifteen electricians and business is slow for a few years, slow enough that you make no profit but not so slow that you have to fire anyone, then the assessed value of the company with fifteen employees doesn't shrink much. Which makes sense: it still has fifteen employees so it's future/long term value hasn't really changed.

Love your thoughts about needing input from others! In Autistic / ADHD circles, the lack of input from other people, and the feedback of thoughts being amplified by oneself is called rumination. It can happen for many multiple ways-- lack of social discussion, drugs, etc. AI psychosis is just rumination, but the bot expands and validates your own ideas, making them appear to be validated by others. For vulnerable people, AI can be incredibly useful, but also dangerous. It requires individuals to deliberately self-regulate, pause, and break the cycle of rumination.

STEP doesn't preserve all of your design intent (sketches etc.) but it does preserve the geometry (edges, vertexes, faces). So it is a lot easier to work with it because it is lossless and precise. Curves are curves, not quantised/faceted.

So in our image processing analogy, it is still in a sense a "flattened" representation of the layers, but it's a vector format. The best way to think of it is broadly like a 3D SVG, I guess.

https://en.wikipedia.org/wiki/ISO_10303-21

3D printer slicers (except maybe Cura without a paid add-on) can usually load STEP now, but they are still internally meshing before slicing. I think Orca/Bambu/PrusaSlicer all give you some control over that meshing (they all use OpenCascade to do it, in fact).

In FreeCAD you can do things like defeaturing, so if you have a hole in a rounded plate, you can delete the hole, you can delete corner-rounding. You can also break STEP files down to faces and use the surface/curves tool to work on them, or use them as a BaseFeature for a Part Design Body, etc.

This is a pretty useful video for showing the differences:

Flight simulators just had more cash for more advanced chips, but arcade games like the Sega Model 1 (Virtua Racing) was via Virtua Fighter an inspiration for the Playstation, and before that there was crude games on both PC and Amiga.

Games were always going to go 3d sooner or later, the real pressure of the high volume competitive market got us more and more capable chips until they were capable enough for the kind of computation needed for neural networks faster than a slow moving specialty market could have.

I have had fairly extensive hearing loss in my left ear for about 20-something years and finally decided to investigate options about a year or so ago.

I tried a set of Phonaks for about a fortnight, but I found them tinny-sounding (which I'm told you get used to), and their automatic mode switching (for when you walk into noisy rooms) was incredibly frustrating.

A month later, Apple dropped the Airpods Pro hearing-aid mode software update and I have never looked back. The feedback from my family has been overwhelmingly positive, which more than offsets any qualms I had about them being so visible when you wear them.

My (obviously subjective) view is that the sound quality of the AUD$400 set of Airpod Pro 2s completely smokes the AUD$5,000+ set of Phonaks, and that's before you account for all the UX niceties you get from Apple when you play in their ecosystem (virtually seamless transition between phone, computer and TV (with AppleTV box)).

The fact that you can run an on-demand hearing test on your phone for free, giving you the ability to track any decline yourself without having to front up to an audiologist is just the icing on the cake.

There's more detail and multiple anecdotes elsewhere, eg:

It’s estimated that, each year, 12 million girls around the world are married before they turn 18. The perception that child marriage is something that happens to other kids in other places – not the United States – is a false one. Between 2000 and 2021, nearly 315,000 children were legally entered into marriage across the U.S. The vast majority were girls wed to adult men.

~ https://www.unchainedatlast.org/united-states-child-marriage...

Mandy’s mother encouraged her to become affectionate with the man from their church in Arizona who was showing an interest in Mandy. He was aged 18. Mandy was 12. His grooming and abuse continued for years, fully sanctioned by Mandy’s mother, who spoke of God’s plan. He proposed to her four years later, and she tried to say no. After exhausting every possible way to escape what her parents were forcing her to do, she ran away, but as a minor, she had no power. Her parents were able to force her back home and into marriage. Mandy was married a week after her 17th birthday to her 23-year-old longtime rapist and abuser. She was trapped in a marriage marked by relentless emotional, physical, verbal and financial abuse. When Mandy finally escaped as an adult, at age 20, she was excommunicated from her church. She lost all her family and friends. She was left to rebuild her life on her own.

Church groups and family pressuring marriages arranged from a very young age are pretty much the norm for "forced marriages", more common than actual trafficing by strangers.
