I do CUDA for a living (not inference) and for the life of me (and a couple of LLMs for that matter) I cannot figure out what you mean by "SM pairs".

Do you mean the coupled dies on stuff like the B200? An NVidia chip die has many SMs if so.

Do you mean TMEM MMA cooperative execution? I'm guessing that must be it given what the paper is about.

False dichotomy. Terminal debugging is garbage. The GUI you use for writing code doesn’t have to be the same GUI you use for debugging code.

I mostly edit code in VSCode. I mostly debug code in VisualStudio. They don’t have to be the same.

I do concede that one tool to rule them all is appealing. But ultimately I work with many different languages so it’s kind of a multi-tool world no matter how you slice it.

It's quite hilarious that you link to an EA forum to make your point when it's a known fact SBF was from the EA movement and they openly discussed --after the SBF/FTX/Alameda fraud was exposed-- whether scamming people to give part of the money they stole to fund things they thought would make EA participants look as white knight was acceptable or not.

The best example is SBF's guru who bought a 15 million GBP mansion in the UK for the EA movement with stolen funds.

Now he's keeping a very low profile because I know for a fact that up to a few years ago there was still assets being clawed back from the Enron fraud (!). So that mansion could be seized one day from the EA movement.

Let's steal money, let's buy private jets and fancy villas for our parents in tax heavens, let's give some to worthy cause (worthy in their own eyes).

Despicable people this EA movement.

And, no, I'm neither taking lessons nor explanations from what are, in the end, just petty scammers / thieves.

Agreed its a stretch, my experience comes from Google when I worked there and they set up a Chinese office and they were very carefully trying to avoid anything on premises that could searched/exploited. It was a huge effort, one that wasn't done for the European and UK offices where the government was not an APT. So did X have the level of hygiene in France? Were there IT guys in the same vein as the folks that Elon recruited into DOGE? Was everyone in the office "loyal"?[1] I doubt X was paranoid "enough" in France not to have some leakage.

[1] This was also something Google did which was change access rights for people in the China office that were not 'vetted' (for some definition of vetted) feeling like they could be an exfiltration risk. Imagine a DGSE agent under cover as an X employee who carefully puts a bunch of stuff on a server in the office (doesn't trigger IT controls) and then lets the prosecutors know its ready and they serve the warrant.

There is video evidence and many eyewitnesses that he did no such thing. If you need to lie to justify fascism, maybe you shouldn't be supporting fascism.

He possessed a weapon on his person in a state where that in completely legal, in a country whose constitution explicitly says he's allowed to own that weapon. There was not a single reason for him to be executed by federal agents.

Don't combine it with von Neumann probes and you've solved the Fermi paradox: a civilization that puts that much work into computing power is either doing the equivalent of mining crypto and going nowhere, or is doing AI and is so dependent on it that they inevitably form a vast echo chamber (echo sphere?) that only wants to talk to itself (itselves?) and can't bear to be left out by adding the latency unavoidably added by distance.

tl;dr: civilizations advanced enough to travel between stars end up trapped by the resources and physics required to keep up with the Joneses.

> Yes, and the made up words of kilo and kibi were given specific definitions by the people who made them up

Good for them. People make up their own definitions for words all the time. Some of those people even try to get others to adopt their definition. Very few are ever successful. Because language is about communicating shared meaning. And there is a great deal of cultural inertia behind the kilo = 2^10 definition in computer science and adjacent fields.

> Industry OTOH has gone all-in on Transformers.

It's so annoying. Transformers keep improving and recurrent networks are harder to train so until we hit some real wall, companies don't seem eager to diverge. It's like lithium batteries improving easy faster than it was profitable to work on sodium ones, even though we unfortunately want the sodium ones to be better.

The energy economics in space are also a bit more complicated than usually thought. I think Starlink has been using Si cells instead of III-V-based ones, but in addition to lower output they also tend to degrade faster under radiation. I guess that's ok if the GPU is going to be toast in a few years anyway so you might as well de-orbit the whole thing. But that same solar cell on Earth will happily be producing for 40+ years.

Also the same issue with radiative cooling pops up for space solar cells - they tend to run way hotter than on Earth and that lowers their efficiency relative to what you could get terrestrially.

Generally you'd need a killer app/device designed from the standpoint of a vision and once the app/device spreads, so does the vision.

I had the idea of a trashcan that knows what's being thrown away, say with a handheld barcode scanner. The product can be a wifi connected barcode scanner. Each time you scan something, you'd say something like: need 3 more now, past expiry, didn't like, find alternative, order more in 2 weeks. And that barcode scanner would do the ordering through an Agent for replacements.

Not sure if it needs to be wifi connected, but needs web access somehow at some point.

On the other side, suppliers would pay to access and fulfill these orders. Eventually that would be done by Robotaxis and drones. There could be a screen attached to this barcode scanner too ( see this: https://news.ycombinator.com/item?id=46699782 )

So I guess the goal is to setup a site MyStuff. And aim to slot in OmniLinux in there.
Also worth taking into account the recycling aspect.. trash is money.

Maybe you could even take the scanner shopping to discover and scan things with it... not sure how retailers would feel about that.

But yeah, this is just zooming in on a starting point. The other idea I had was community notice boards. Always important across the world, especially for launching a business. Maybe they could have little cameras in them to record new pinups. Sell to local councils.

So with MyStuff, I am not sure how that overlaps with IoT and Tokenization, some things would be assets, some just things.

Maybe get a really good website going and find a way to let people populate it with data.

I am attempting to move away from smartphones as well. Maybe there's a way to give away these scanners for free or provide rebates if the data they collect is solid and/or leads to real transactions. Can also be used as a crypto wallet in face-to-face transactions. That'd be nice - and a way to limit the loss if the scanner is lost/stolen.

Good luck.

Increasing federal power is what is going to lead to balkanization. Now that the 10th amendment is null and void the executive and federal government have nearly limitless power, particularly through expanded interpretation of the commerce clause, we find ourselves in a hell where we teeter between two extremes who badly both need to get into power to not be dominated by the other.

Allowing states to differ wildly was what let bygones be bygones, but no we can't have that anymore, everything nowadays seems to need to be imposed on everyone via 190,000 pages of federal regulations and 300,000 federal laws.

I despise AppArmor and SELinux, especially in cases where they actively get in the way of security like this.

But you shouldn't need to make a global change. Do this:

if [[ -f /proc/$$/attr/exec ]]; then
# AppArmor is active. Request "unconfined" for our next exec.
echo 'exec unconfined' 2>/dev/null >/proc/$$/attr/exec
fi
exec ...

Or I think you can do this:

$ setpriv --apparmor-profile=unconfined [command]

(You'd think I'd be more sure of the exact circumstances under which the latter works given that I literally wrote setpriv... At the very least, it will error out if apparmor is not running, which is mildly obnoxious.)

> xAI needs money to win the AI race

Off on a tangent here but I'd love for anyone to seriously explain how they believe the "AI race" is economically winnable in any meaningful way.

Like what is the believed inflection point that changes us from the current situation (where all of the state-of-the-art models are roughly equal if you squint, and the open models are only like one release cycle behind) to one where someone achieves a clear advantage that won't be reproduced by everyone else in the "race" virtually immediately.

You know police are not all technically clueless, I hope. The French have plenty of experience dealing with terrorism, cybercrime, and other modern problems as well as the more historical experience of being conquered and occupied, I don't think it's beyond them to game out scenarios like this and preempt such measures.

As France discovered the hard way in WW2, you can put all sorts of rock-solid security around the front door only to be surprised when your opponent comes in by window.

I am so confused at how this is supposed to work. If the code, running in whatever language, does any sort of transform with the key that it thinks it has, doesnt this break? E.g. OAuth 1 signatures, JWTs, HMACs...

Now that I think further, doesnt this also potentially break HTTP semantics? E.g. if the key is part of the payload, then a data.replace(fake_key, real_key) can change the Content Length without actually updating the Content-Length header, right?

Lastly, this still doesnt protect you from other sorts of malicious attacks (e.g. 'DROP TABLE Users;')...Right? This seems like a mitigation, but hardly enough to feel comfortable giving an LLM direct access to prod, no?

Worth noting that a majority of the NRC is now Trump appointees. And last month, he named the new chair of the NRC, and pretty much immediately they published new rules that are going to allow nuclear startups connected to Trump-friendly investors to fast-track construction:

The point is that it's nonsensical to say flying is cheaper than driving. Its oranges vs apple. Apples and oranges are fruit, flying and driving are transportation. But they're totally different.

1. You're normalizing one cost by the occupancy but assuming the other is single occupancy.

2. The assumption that folks are alone in a car is only true only for short trips, trips that are unpractical and expensive by plane. Folks don't fly 600+ mi because it's cheaper (the fuel isn't cheaper until about 1600 mi), but because it's faster.

I posted this yesterday but did some work on it since. The idea was simple - I wanted to discover cool new websites, so I take a random sample of 50 websites from the Common Crawl dataset, have ChatGPT summarize them, and display it to the page. Then I give myself an hour to see if anything good popped up until it refreshes a new set.

There's a lot of noise and corporation I want to figure out how to filter out, but I've otherwise been finding all kinds of fun weird stuff. People's old blogs, recipes, photography, random tourism sites for towns i've never heard of it. It's been fun.

This is written by someone that is not in aerospace that thinks terrestrially.

Engineering is always a question of tradeoffs.

Launch costs are dropping, and we’re still using inefficient rockets. Space elevators & space trains, among others, can drop this much more, the launch costs are still dropping, even using rockets, maybe we’ll never get to elevators & trains the costs will drop so low!

Radiation shielding is not required for VLEO or LEO, and phenomenally more capable aerospace processors are near - hi Microchip Inc! There are many other radiation solutions coming, no doubt with nuclear power.

Satellites can be upgraded at scale, though for many things, it does not make $ sense to upgrade them, but fuel , reaction wheels, solar panels, among other things do make $ sense to replace.

Latency was technically solved in 1995 & 2001 with the first laser comms missions NASDA’s ETS-VI kiku-6 and ESA’s Artemis , and Laser crossbars for comms are common. A full laser TDRS no RF is not yet extant but soon. Earth to deepspace was just demonstrated by ESA.

Cooling can be significantly improved due to lower launch costs, heat piping, RTGs, TEGs, and thermoradiative cells, not to mention sunside solar and darkside inline radiators

Furthermore, it is very likely that as neuromorphics with superior SWaP emerge, we could see very different models of space based computation.

Economic tradeoffs should drive many of these decisions as I’m not discussing the other applications of datacenter in space

Why don't you try it out in Opencode? It's possible to hook up the openrouter api, and some providers have started to host it there [1]. It's not yet available in opencode's model list [2].

Opencode's /connect command has a big list of providers, openrouter is on there.

"There is a herculean effort on the part of package maintainers to build software for distros, and no one has been building 32 bit version of software for years, even if it is possible to build from source."

This statement must be Linux-only

Pre-compiled packages for i386 are still available for all versions of NetBSD including the current one

I still compile software for i386 from pkgsrc

RNNs have two huge issues:
- long context. Recurrence degrades the signal for the same reason that 'deep' nn architectures don't go much past 3-4 layers before you need residual connections and the like
- (this is the big one) training performance is terrible since you can't parallelize them across a sequence like you can with causal masked attn in transformers

On the huge benefit side though you get:
- guaranteed state size so perfect batch packing, perfect memory use, easy load/unload from a batch, O(1) of token gen so generally massive performance gains in inference.
- unlimited context (well, no need for a concept of a position embedding or similar system)

Taking the best of both worlds is definitely where it is at for the future. An architecture that can train parallelized, has a fixed state size so you can load/unload and patch batches perfectly, unlimited context (with perfect recall), etc etc. That is the real architecture to go for.

Right. The alternative is not to send materials from Earth for processing in space, that would be stupid. We send finished stuff, which were manufactured on the ground. But you don’t mine finished widgets from asteroids. You mine ore that needs refining and processing before being used to manufacture things. This ore is orders of magnitude heavier than the finished products, never mind all that’s required to do anything useful with it.

Except it's not because it's constantly ambiguous in computing.

E.g. Macs measure file sizes in powers of 10 and call them KB, MB, GB. Windows measures file sizes in powers of 2 and calls them KB, MB, GB instead of KiB, MiB, GiB. Advertised hard drives come in powers of 10.

Argentina has debt in foreign denominated bonds though - the US (and UK, Japan, Canada, Australia, NZ, etc.) don't, only issuing bonds in their own currency, which makes a massive difference.

Not to say that Trump isn't wreaking economic havoc and madness, but the USD is resting on a far stronger base than somewhere like Argentina.

Some people seem to think the previous space race was about technology. That was all incidental. The Space Race was entirely geopolitical. It was a conflict proxy, an artifact of the Cold War. Any technology was entirely incidental.

The US has been talking about a return to the Moon for 50 years. George W Bush talked about it in 2004. It still hasn't happened. Artemis is limping along but it's entirely pork barrelling for the overly expensive SLS program that really no future.

Some might say SpaceX will come to the rescue. That's... doubtful. Notably, Elon calls the Moon "a distraction" [1]. Why would he do this? It's free money from the government.

The answer is actually pretty simple: Tsarship simply isn't designed for this mission type. Landing a Starship on the MOon is much more complex than, say, the LEM for the Apollo missions or the proposed Chinese lunar lander. If you could, your astronats would be 40 meters off the ground. The big advantage of a "traditional" lunar lander is it can't really topple over. Plus the Apollo LEM also had a very simple engine that could only ever be used once but the big advantage was that it was extremely difficult to fail.

If you exclude all that, Starship is behind schedule and still requires developing technology that they haven't even begun to test, most notably in-orbit refueling.

So why is China doing all this? I suspect it's mainly to develop their own reusable rocket program with a side of national pride. China is very concerned with their national security interests. Being able to launch things cheaply is a critical national security interest.

Still, the mission architecture of China's mission (from what I've read) is still fairly complex, requiring two vehicles to rendezvous in lunar orbit. That's also why I think the primary goal is orbital launch capacity.

Oh hey, I have one of these! I really like it. It's quite a unique design. People (especially where it snows and gets gloomy) should have more lumens, and I'd recommend this lamp for others.

One downside is that the active fan cooling design is questionable - the air goes over the top of the LEDs, and there aren't any dedicated exit holes so the air is just squeezing through the very small gap between the glass and the heatsink.

This is a bad example. I've been notionally pro-ownership but also pro-regulation my whole life, and one of the major problems with gun legislation in the US is that it's incredibly poorly written and does not reflect the technical reality of guns.

The government allows private ownership of automatic weapons, but hasn't issued any new tax stamps for 50 years. You can convert any semiauto gun into a full-auto gun for a few cents of 3D printed parts (or a rubber band). The hysteria over "assault weapons" basically outlawed guns that _looked_ scary, while not meaningfully making anyone safer.

I think yes, it is reasonable for Congresspeople to fire a gun before they legislate on it, because otherwise they are incapable of writing good laws.

Good gun regulation in the US would probably look like car insurance, where gun owners need to register and insure their weapons against the possibility of crimes being committed with them. There are so many guns compared to the amount of gun crime that it would probably not end up terribly expensive, especially if you own a gun safe.

> So "Just don't be gay/smoke weed, it's not legal, if you don't like it there's a process to get that changed" is the kind of viewpoint that's compatible with your ideology then?

Sure (although I don't think there's ever been a law against being gay, only against particular acts).

> There MUST be room for petty noncompliance to let people discover that the noncompliance in some unknown case is perhaps not bad in order to kick start the process.

Petty noncompliance isn't the only source of information, and even if it was, that doesn't negate the cost to society.

> People like you are actively working to prevent and delay alignment between the people and the government/laws. If everyone subscribed to your ideology nothing would ever get done. If more people subscribed to it then things would change slower than they do.

So the wild swings of public opinion will be tempered somewhat, and society's path will be smoothed. Yes, that's the point. Same spirit as having a constitution and a second chamber rather than making everything run on a simple majority.

> I'm not saying go murder your neighbor because "fuck the law" or whatever

But you are. That's where your ideology leads once people start following it in practice.

and further:

Among other things, Acosta allowed Epstein’s lawyers unusual freedoms in dictating the terms of the non-prosecution agreement.

“The damage that happened in this case is unconscionable,” said Bradley Edwards, a former state prosecutor who represents some of Epstein’s victims.

“How in the world, do you, the U.S. attorney, engage in a negotiation with a criminal defendant, basically allowing that criminal defendant to write up the agreement?”

if nothing else, the bald exposure of a two tier "justice" system is grounds enough for outrage in the Epstein case.

The deliberate coverup of co conspirators adds fuel to the fire, and the nature of the crimes really brings it all home.

To get on the same page as SpaceX, they patented a satellite chassis optimized for heat dissipation in 2020:

https://patents.google.com/patent/US11834205B1/en

The sample they built gets 12.4 watts / kilogram, a good deal better than state of the art, but still short of competitive with Earth data centers even with optimistic cost assumptions. But at least SpaceX is way beyond the napkin, and has real data to work with.

Yes sadly that sometimes happens - the issue is Codex CLI / Claude Code were designed for GPT / Claude models specifically, so it'll be hard for OSS models directly to utilize the full spec / tools etc, and might get loops sometimes - I would maybe try the MXFP4_MOE quant to see if it helps, and maybe try Qwen CLI (was planning to make a guide for it as well)

I guess until we see the day OSS models truly utilize Codex / CC very well, then local models will really take off
