Since this was posted I've been heads-down building on top of the neural CPU. Wanted to share what's new.

Built a GPU-Native UNIX OS. A full multi-process operating system running compiled C on Apple Silicon Metal:

> 25-command shell (ls, cd, cat, grep, sort, uniq, tee, cp, wc, pipes, background jobs, chaining, redirect) — ~17.5KB freestanding C compiled with aarch64-elf-gcc -O2, running entirely as ARM64 on the GPU

> Multi-process: fork/wait/pipe/dup2 via memory swapping. 1MB backing stores, up to 15 concurrent processes, round-robin scheduler, pipe blocking/wakeup, fork bomb protection, SIGTERM/SIGKILL, orphan reparenting. 28 syscalls total.

> Freestanding C runtime: malloc/free/printf/fork/wait/pipe/qsort/strtol — all on GPU

Self-hosting C compiler on Metal GPU. cc.c (~2,800 lines) compiles C→ARM64 entirely on the GPU, then executes the output on the same GPU. Three layers: host GCC → GPU compiler → GPU-compiled binary. Debugged 5 codegen bugs to get it working (UBFM encoding, LDURSW sign-extension, caller-save clobbering, array subscript type clobbering, struct lvalue handling). Supports structs, pointers, arrays, recursion, for/while/do-while, ternary, sizeof, compound assignment, bitwise, short-circuit eval. 20/20 test programs pass. Mean compile: ~50K GPU cycles. Ackermann A(3,4) runs 319K cycles of deep recursion correctly.

13+ compiled C applications on Metal:

> Crypto: SHA-256, AES-128 (ECB+CBC, 6/6 FIPS vectors pass), encrypted password vault
> Games: Tetris, Snake, roguelike dungeon crawler, text adventure
> VMs: Brainfuck interpreter, Forth REPL, CHIP-8 emulator
> Networking: HTTP/1.0 server (TCP proxied through Python)
> Neural net: MNIST classifier (784→128→10, Q8.8 fixed-point)
> Tools: ed line editor, self-hosting C compiler, Game of Life

neurOS — fully neural operating system. 11 trained models running MMU (100%), TLB (99.6%), cache (99.7%), scheduler (99.2%), assembler (100%), compiler (95.2%), watchdog (100%) — zero fallback paths.

Self-compilation verified: source → neural compiler → neural assembler → neural CPU → correct results.

Timing side-channel immunity. Measured sigma=0.0000 GPU cycle variance across 270 runs of AES-128. Same code on native Apple Silicon: 47-73% CoV. No caches, no branch predictor, no speculative execution inside a dispatch. T-table timing attacks are structurally impossible.

Just reorganized the whole project — neurOS and GPU OS now live under a clean ncpu/os/ package (neuros/ and gpu/ subpackages). 850 tests passing, all verified after the reorg.

To @andreadev — the MUL>ADD inversion is still my favorite result. To @bob1029 — you're right about branchy workloads being slow (~5K IPS neural, ~4M compute), but the GPU execution model gives security properties CPUs architecturally can't provide.

Really like the strict network/domain separation + Lua-at-the-edges approach here. In game servers, once simulation logic and protocol plumbing get tangled, every feature turns into surgery. Keeping a stable C# core and pushing gameplay iteration into scripts seems like the right tradeoff.

Curious if you’ve seen any hotspots at the C#↔Lua boundary under load (e.g. per-tick callbacks on many entities), and whether you batch/cap script invocations per tick to keep tail latency predictable.

I agree, difference between explosive growth and “consistent draw” is large employers setting up in the region.

Another interesting anecdote is that I know many people who work remote for companies all over the world who moved to the Seattle area once they had a remote job. I am one of these people who moved once I got a remote job. Im not sure what kind of impact this has long run. I think the flywheel drawing high skill people to Seattle is still very strong.

UO was the best online game for me. All others stand in its shadow. It was the most "free" in terms of what you could do and the appeal was the non-gamification.

I loved Everquest and World of Warcraft but those didn't feel "raw" enough for me.

The Realm is my dark horse submission for best MMO. (Yea, yea, yeah Meridian 59 and Underlight too)

Don't put words in my mouth, don't say silly things.

I'm well aware the color your skin matters a lot, but your passport also matters, especially at the border.

You're better off with white skin and a US passport than with white skin and a British passport, but you're also better off with brown skin and a US passport than brown skin and a British passport and that's still better than brown skin and a third-world passport.

An interesting policy proposal is negative tax. Basically take the carbon cap, divide by the number of people, and give the equivalent carbon tax price to each person. A person who uses exactly average carbon sees no change, while a person who uses less gets a tax rebate, and a person who uses more pays more. You can charge it at the source, tariffing oil by its carbon content and then reducing taxes by that amount for everyone.

The name of that Department was chosen to be aspirational, to encourage it to try to keep within its Constitutional guardrails, to keep it focused on the right mission.

Sure, it often didn't live up to its aspirations and a lot of the fence posts of those Constitutional guardrails got moved, but wearing those aspirations on its sleeve left some room for people to challenge it and openly criticize it by reminding the Department of its guardrails and its mission.

The name change is disrespectful to the Constitution, if not terrifying for other reasons.

> And some kids haven't got their head straight after puberty at 16, and still need (or would have needed) the training wheels.

But on average they don't.

> Society works on averages.

Right. So setting the rules around the outliers is wrong. Glad you're clear on that.

> Most people being ready little adults at 16 doesn't mean everyone is.

You don't have to be a completely self-sufficient adult to handle the freaking Internet.

If the author had been paying attention _while it was happening_, rather than looking back at history and re-stating it to fit his mental model, he would have seen something else.

Namely, the whole story of the rebound is Nicolas Hayek and Swatch. You see, at the explosion of quartz watches, everyone already had a drawer full of Rolexes and Pateks and AP's. They had done that. But telling time? More accurately? That was actually pretty boring.

Nicolas Hayek became a hero. It's fair to say, yes, he consolidated ASUAG + SSIH and built volume and all that. But really? It was about Emotion and redefining the Essential Function of a watch.

Swatch made Swiss watches cool again. The marketplace was saying Japan vs. Switzerland and quartz vs. old fashioned gears. Swatch rejected that and said "fun, whimsical. Wear not one, but several. You be you." What landed the message was wealthy Swiss keeping the Rolex in the drawer and believing in the the $19 Swatch. Aston Martin and Swatch. That was the way to roll.

It became a thing, the kids bought in, and the Swiss Watch Industry (Big Watch, lol) stayed relevant vs. Japan. It was a country vs. country fight and Swiss prevailed on creativity.

Swatch was such a watershed moment, tha that across Europe the key to Industrial Success became "Personalized Mass Production." Why? Because swatch quickly grew to be able to launch 2x70 models a year. The German Industrialists included personalized mass production and innovation in every slide deck for the next 20 years. And if you don't think that matters, look at Zara, and then Shein. Same playbook as Swatch. Swatch changed everything.

It’s largely impossible now, it’s not a technical problem, it’s cultural.

UO forced many different types of players to coexist in the same world that simply do not mix anymore. You had peaceful dungeon crawlers and craftsmen coexisting alongside killers, rapists, thieves (wild that stealing items from other players inventory was actually a thing, probably unheard of in today’s MMOs).

The friction between these different types of players is where the magic happened, it’s what created real conflict and higher stakes in the world. When you stepped out of your house, there was always a risk that killers could be lurking ready to murder you and loot your house dry. And if you forget to lock the door, someone passing by will clean your house out for anything valuable.

In a way, old school UO was a true Middle Ages type MMO, everything since then has only grown more civilized, more enshittified. People don’t want to pay for a world that doesn’t give a shit if they have a bad experience. The truth is though there was no “bad experience”, it was all just an experience.

It’s a winning playbook. Con a bunch of disenfranchised people worried about being left behind in the tech economy and worried that their bloodlines are getting polluted by Juan (sic) by aligning yourself with their xenophobia and racism and promise them everything they want to hear: America first, no new wars, let’s get tired of winning, own the libs, … and then win and then forget about those useful idiots. Rinse and repeat.

You're arguing a hypothetical where the US stopped all emissions 100% and the rest of the world isn't doing anything.

The reality is that China is aggressively pushing solar and electric vehicles, and the West is complaining about it. Meanwhile the current US president's maxim is "drill baby drill".

I mean, if we don't need to stick to facts, let's discuss the hypothetical scenario where I am a powerful wizard, and when I say a magic word and I can halve the total amount of CO2 in the atmosphere?

OK, now where's my Nobel peace prize dammit??

Yea that's a fair take

Like you will go to an election, and your choices will be

Republican candidate: "I support deporting your family, I will not only not support cleaner energy but will actively work to increase coal usage, and I think your trans cousin should be forced to transition back even if it makes them commit suicide."

Democratic candidate: "I think all of that stuff the Republican candidate said is crazy and wrong. If elected, I will strive to make all your guns illegal, so that eventually Republican-supporting institutions like the police and military, and Republican states, are the only ones with guns."

Biggest assistance Russia will end up providing is preventing any "boots on the ground" from Azerbaijan/Turkey, given that the only really viable way to get to Teheran is from the north.

That said Aliyev, despite the drone attack on Nakhichevan and his "alliance" with Israel, is probably not going to do anything because he is also sitting very pretty with oil and LNG disruptions.

Ridiculous take that Florida is expensive like it's some kind of luxury trip.

Florida was always a budget option for us. It's always been a quick, easy (you can drive), low risk break to get away from the cold. I just don't feel like dealing with CBP and random MAGAs right now to be honest. Wife is low-key stressed about the idea. I mean at best it's a hassle... so why bother?

Do note that senior manager thinking the work is redundant also might be completely not aligned with reality. so "I think your work is redundant" is much closer to usual reality. And it's easy to be seen that as you pretty much also need to be a PR person for your own department, not just a manager, especially if department is doing necessary but not glorious tasks

The bugs are at least of the same quality as our internal fuzzing bugs. They are either crashes or assertion failures, both of these are considered bugs by us. But they have of course a varying value. Not every single assertion failure is ultimately a high impact bug, some of these don't have an impact on the user at all - the same applies to fuzzing bugs though, there is really no difference here. And ultimately we want to fix all of these because assertions have the potential to find very complex bugs, but only if you keep your software "clean" wrt to assertion failures.

The curl situation was completely different because as far as I know, these bugs were not filed with actual testcases. They were purely static bugs and those kinds of reports eat up a lot of valuable resources in order to validate.

> mildly right leaning

This is nonsense even if we calibrate to North America and the EU (versus the American voting public).

Within America, Democrats are center left. Internationally it’s a hodgepodge of left-wing social, centre right-wing foreign and across-the-board economic policy.

It’s fine to say the part is right of your preferences. But it doesn’t help your argument to be delusional about where other Americans stand.

Politicians, at least freely elected, are a symptom of given population at given time. Don't blame trump for trump, he made it painfully obvious to whole world who he is and who he certainly is not, sort of kudos to him for being consistent.

Blame fully the people who saw all this and voted for him twice. At least if you care about root of the problems and not just venting off. I am not offering a solution to educating half of US population which clearly doesn't care about facts, or lacks any basic moral compass... I don't have a practical solution.

US 'special' form of voted democracy failed and failed hard, lets see how far this gets in next 3 years and if any actual lessons learned happen afterwards (I don't hold my breath since reality doesn't behave just because it would be nice and viable time to act is gone I think).

we have had several manhattan project in the last 100 years, but they have all been for stuff like:

- creating a new addictive form of entertainment we can use to brainwash people

- Creating expensive data centers that MAY end up being extremely useful in the long run

and never for saving the lives of the people on our planet.

Humanity is doomed. We deserve it.

Oh, I know it happens. Over the years AWS has added functionality across various services to help prevent accidental deletion, but absent some documented behavior to the contrary, when a customer confirms that data is to be deleted, AWS is supposed to make that data completely inaccessible by anyone, including AWS themselves.

I updated my comment above because I have a theory as to what really happened here, and it doesn’t involve support recovering deleted snapshots.

Collective Intelligence Project | Lead Product Engineer | Remote (US time zones, PST preferred) | $150k | https://www.cip.org/careers/productengineer

The Collective Intelligence Project (http://www.cip.org) builds platforms that allow large groups of people to participate in decisions about AI systems. In short, we’re building the democratic infrastructure for AI.

We partner with AI labs and governments to evaluate frontier models on questions automated benchmarks can’t capture — e.g. whether models respond safely to mental health crises, provide reliable legal advice across languages, or exhibit political bias.

We’re looking for a Lead Product Engineer to build infrastructure behind this work.

You’ll work on:
- evaluation platforms used by AI labs and policymakers
- systems for collecting and aggregating large-scale human judgment data
- interfaces that help policymakers interpret evaluation results
- infrastructure for large-scale public deliberation about AI

Stack currently includes: TypeScript, React/Next.js, Postgres, Supabase, Vercel. You’ll have significant ownership over architecture and product direction. We’re hoping candidates are already familiar with Claude Code / Codex / Cursor, and are excited about using AI as a force amplifier across projects.

If you're interested in building infrastructure for democratic AI governance, we'd love to talk.

Apply here: https://www.cip.org/careers/productengineer

Depending on the tree, freshly cut wood can have anywhere from 1:3 to 2:1 ratio of water to actual wood fiber.

So, unless we want to remove a massive amount of fresh water from the ecosystem, we also need to invest energy in drying out the wood well below natural humidity levels (transport to a desert maybe?) on top of electrifying what is currently a diesel and gas heavy industry (cutting and transporting logs with heavy machinery).

There's definitely lower hanging fruit for getting C02 out of the cycle.

Don't kid yourself - we closed this one with "Won't Fix" a while ago.

"But what about <technology/option>?"

No. Full stop. We're not going to do it, and we're not even going to apologize for it either.

All we can do now is prepare, not that I've seen a lot on this front either.

I've been building OrchEngineX, a distributed systems simulation platform for exploring cascading infrastructure failures.

The goal is to model structural fragility in service architectures — things like retry amplification, connection pool exhaustion, latency propagation, and dependency cascades.

To demonstrate it, I ran a simulation where a small 2% latency spike triggers cascading database connection pool exhaustion in a 20-service architecture, eventually collapsing the system without any servers actually failing.

The article includes the failure breakdown as well as the simulation used to produce the results.

I'm currently building the public simulation lab where engineers can design their own architectures and run failure simulations.

Would love feedback from people working on distributed systems, reliability engineering, or large-scale backend infrastructure.

Regarding carbon capture, it will take more energy to capture the carbon than we burned putting it up there in the first place. Alan Kay, who actually did some systems work on the environment, explained it to me that the climate system is like an upside down coke bottle. It doesn't take much energy to tip it over, but it takes a lot more to put it back up.

In other words, we shouldn't have tipped it over in the first place. We may not have the energy to put things back to a habitable place.

Funnily enough, they didn't let Claude rip:

The agent kept deleting files, and at some point, it output: “I cannot do it. I will do a terraform destroy. Since the resources were created through Terraform, destroying them through Terraform would be cleaner and simpler than through AWS CLI.”
That looked logical: if Terraform created the resources, Terraform should remove them. So I didn’t stop the agent from running terraform destroy.

They actually reviewed the agent's suggestion before running it. It's just that they accepted it anyway because they didn't understand Terraform enough to realise what it'd do. The agent didn't either, and didn't have enough security mindset to do a `terraform plan -destroy` beforehand, which would have revealed the mistake.

As one of those kids, you could’ve just stopped at “I don’t think”, because you’re not thinking critically if you think we don’t exist.

I wasn’t allowed to have a personal device or unsupervised internet access until I graduated.

My parents forced me to go to a school with a summer work program. I was yeeted to university by my wing clipping abusers THREE DAYS AFTER GRADUATION.

Rural, miles from the nearest town of 1200 so I didn’t have access to the resources needed to change any aspect of this.

I was deeply hampered by this, and despite being one of the salutatorians of my graduating class (we had ties due to AP), I crashed out of that university after a semester.

@laurex or whoever made this, well done! It's a great example of how an LLM can serve the public interest by summarizing and structuring news of a court case across its duration.

The design is very good. One suggestion: Consider having the LLM use bullets for the longer summaries, such as "KGM (Kaley) — The Plaintiff Takes the Stand." This will relieve the reader of facing a wall of text.

Also, regarding "Every claim sourced from live web search": For me, that phrase created the expectation that every claim made by the various participants would be itemized. Instead, the system seems to be capturing the claims in news reports of testimony. That's not a bad thing. Most people probably would prefer the focus on key claims reported in the news, as opposed to a long list of all claims, many mundane. But it's worth thinking about whether a different tagline phrase would better communicate what's being delivered.

> Kids are smart and easily learn how to work around restrictions.

Absolutely. I feel like adults frequently mistake kids’ lack of education for stupidity. Lack of education about something is a temporary condition, and kids have ridiculous amounts of time, energy, and motivation to quickly become expert about something they care about. Particularly in reaction to “you can’t do that.”

One possibility: These laws forget that 18 year olds have kid siblings. The 18 year olds need money and like everyone else, enjoy the prospects of easy money. The 18-year-old has a phone bill to pay. These are the makings of a black market. Kid sibling acts as a broker for the older sibling’s services among the kid’s classmates and collect a commission.

Your reply did exactly what I complained about: expanding the definition of emulator to cover reimplementing a network protocol.

You're not wrong that "server emulator" is a generically correct use of the term emulation, in the same sense that it is a correct use of the word for someone to say they emulate a fashion sense of a celebrity they like in their own wardrobe.

But in computer science, strictly speaking, the original definition of emulator was more strict. It was about things like emulating processor architecture A so as to execute programs written for it on processor architecture B.

And part of why expanding the definition to include "server emulators" annoys me is why has this definition expansion occurred only in gaming contexts? If a free UO server is a "server emulator" then why is Samba not also a server emulator? The lack of consistency is irritating to me, and it only happened because gamers like the term emulator, not due to any kind of rigorous computer sciencey reason.
