Wattage = V x A.

They’re pointing out that it’s impossible to hold both wattage and voltage constant while changing the amperage.

I’m guessing you weren’t around in the 90s then? Because the amount of money set on fire on stupid dotcom startups was also staggering.

The scale is very different. OpenAI needs to raise capital at a valuation far higher than any other startup in history just to keep the doors open another 18-24 months. And then continue to do so.

There’s also a very large difference between far ranging bad investments and extremely concentrated ones. The current bubble is distinctly the latter. There hasn’t really been a bubble completely dependent on massive capital investments by a handful of major players like this before.

There’s OpenAI and Anthropic (and by proxy MS/Google/Amazon). Meta is a lesser player. Musk-backed companies are pretty much teetering at the edge of also rans and there’s a huge cliff for everything after that.

It’s hard for me to imagine investors that don’t understand the technology now but getting burned by it being enthusiastic about investing in a new technology they don’t understand that promises the same things, but is totally different this time, trust me. Institutional and systemic trauma is real.

(took about 15 years because 2008 happened).

I mean, that’s kind of exactly what I’m saying? Not that it’s irrecoverable, but that losing a decade plus of progress is significant. I think the disconnect is that you don’t seem to think that’s a big deal as long as things eventually bounce back. I see that as potentially losing out on a generation worth of researchers and one of the largest opportunity costs associated with the LLM craze.

Sure, but those are largely the big tech companies you’re talking about, and research tends to come from universities and private orgs.

Well, that’s because the hyperscalers are the only ones who can afford it at this point. Altman has said ChatGPT 4 training cost in the neighborhood of $100M (largely subsidized by Microsoft). The scale of capital being set on fire in the pursuit of LLMs is just staggering. That’s why I think the failure of LLMs will have serious knock-on effects with AI research generally.

To be clear: I don’t disagree with you re: the fact that AI research will continue and will eventually recover. I just think that if the LLM bubble pops, it’s going to set things back for years because it will be much more difficult for researchers to get funded for a long time going forward. It won’t be “LLMs fail and everyone else continues on as normal,” it’s going to be “LLMs fail and have significant collateral damage on the research community.”

There is real risk that the hype cycle around LLMs will smother other research in the cradle when the bubble pops.

The hyperscalers are dumping tens of billions of dollars into infrastructure investment every single quarter right now on the promise of LLMs. If LLMs don’t turn into something with a tangible ROI, the term AI will become every bit as radioactive to investors in the future as it is lucrative right now.

Viable paths of research will become much harder to fund if investors get burned because the business model they’re funding right now doesn’t solidify beyond “trust us bro.”

Hardware like that has been and is still being donated through third parties daily.

It’s more in Ukraine’s interest to limit the use of Starlink to only those terminals that have been vetted through official channels than to allow blanket use and try to filter out things through other means due to… the exact kinds of situations this article is talking about.

but that would require the CEO of the company to actually want to help honestly.

Sure. And part of the reason we know Starlink is entirely capable of geofencing is because Elon’s done it explicitly to stop Ukraine from being able to operate near Crimea. That whole kerfuffle lead to military usage being pushed over to Starshield and a contract with the US government that gives them explicit say on when and where Starlink works in Ukraine.

Elon is dumber than a bag of hammers but it’d be next level stupid even for him to willingly break a DOD contract, especially when people were already floating the idea of invoking the Defense Production Act last time around.

The old FourSevens Quarks used to rotate the tailcap the switch between modes. I’ve got one of the older QT2L-Xs that’s probably my favorite light ever for that reason. That and it’s the perfect size for pocket carry while still being decently bright. The newer models since they got bought out ditched it which sucks because it was such a simple interface.

I got a couple of Fenix lights recently that I don’t hate. They still do the “cycle through modes with a button” thing, but it’s at least a dedicated button separate from the tailcap switch.

There are definitely solutions but they all involve giving a Russian agent direct knowledge of troop movements.

Starlink terminals are activated using a unique identifier. It’s how billing works.

SpaceX knows which terminals have been provided to Ukraine. We know they can geofence service. Geofencing the Ukrainian theater to terminals that were provided to Ukraine shouldn’t be a massive technical leap and doesn’t provide any information they don’t already have.

As long as you don’t need particularly tight tolerances or fine details, it works perfectly fine. The setup really isn’t anymore complicated than I described. I have done it just because I wanted to see how difficult the process is. It’s around $100 in startup costs assuming you have access to a printer. After that it’s mostly just waiting and occasionally measuring cut progress.

Check out the Rack Robotics Powercore as well. It’s a low cost wire EDM system that uses cheap 3D printers as a motion platform. It uses a very similar principle to cut metal using wire as the cutting tool. May or may not be more suitable depending on your exact use case. Still pretty rough around the edges though; SendCutSend makes more sense for most people that need things cut from flat stock for the most part.

The majority of components in these things typically are printed. It’s just the pressure bearing components like the barrel where ECM is being used.

The FGC-9 discussed in the article is notable because it was explicitly designed to be manufactured using components that are not regulated as firearms parts under European law. So there are non-printed parts in it, but everything is dual-purpose and can be acquired through unregulated channels, e.g., the hydraulic pipe that gets used as a barrel.

Because Google holds a monopoly position and Epic doesn’t.

That said, the irony didn’t escape me either.

The reality is this is one of a handful of emerging technologies that are going to reshape a lot of things about the world in the future in ways I don’t think society, as a whole, is cogniscent of, let alone prepared for.

This is one of them. The battlefield use of small drones is another.

I tend to say that the world we’re living in now is one where gun control is increasingly obsolete. That’s not a moral judgment. It’s not a statement on whether that’s a good or bad thing. It’s just what I think we’re going to increasingly find to be the new reality: the rise of small scale, low cost, divertible manufacturing technologies is going to make traditional supply-side approaches to regulation untenable. That genie is out.

(Drones are in a similar, if distinct space: low cost, commodity, and divertible from low/no regulation supply chains in a way that makes it nearly impossible to cut off supply without shutting down other legitimate economic activity).

I don’t know what the right answer is. I do think it’s going to take a pretty fundamental rethink of how we approach these problems. I don’t think the full ramifications of these types of technology have really reached the wider zeitgeist, and, frankly, I kind of worry about how people will react. There are a lot of pretty scary paths this could take, both in terms of how the technology gets used and in terms of what attempts to curb them could look like if they’re not carefully thought through.

Machine is borderline overselling it.

The ECM process works by pumping water containing an electrolyte through a metal part. When a current is applied to the water, exposed metal gets slowly etched away.

What these groups are doing is starting with high pressure hydraulic pipe and inserting 3D printed jigs that are basically a negative mask to bore out the pipe to their desired diameter, cut the chamber, machine in rifling, etc, with the end product being a functional barrel. As far as I’m aware, so far this has been limited to pistol caliber cartridges; rifle calibers are a step up in pressure and come with a whole host of different engineering challenges.

The “machine” is really nothing more than a bucket, an aquarium/pond pump, and a desktop power supply. It’s honestly a really clever approach to the problem from an engineering standpoint.

The ECM process isn’t suitable for manufacturing ammunition.

In general, you’d still be generally reliant on the traditional manufacturing supply chain there. There is development happening in that space, but nothing anywhere near as complete as the FGC-9.

Jake Hanhrahan of Popular Front has done really extensive reporting on the general topic of 3D printed firearms. He’s interviewed both people in the design community and people involved in the fighting and manufacture in Myanmar.

our last “just war” that was even a little cut and dry was world war two.

The Balkans were pretty cut and dry in justified intent.

It was an intervention into the worst genocide in Europe since WW2. We’re talking not only wholesale slaughter of civilians, but even the establishment of literal rape camps as part of an organized, systemic campaign of ethnic cleansing. What was happening in the former Yugoslavia was absolutely horrific and the US and NATO stepping in to put an end to it was an unequivocally good thing.

That said, there were still questionable incidents like the “accidental” bombing of the Chinese embassy or the numerous cases of civilians killed by NATO bombs. But that mostly emphasizes the fact that there’s no such thing as a clean war. War is always going to leave blood on your hands, even if it’s being fought for the right reasons.

Crowdstrike is very entrenched in healthcare. Hospitals were routinely at capacity in 2020.

The outage this weekend probably killed some people due to disruptions in delivering care. It definitely would have then.

As somebody that’s a paying Kagi user and generally happy with the service, it is interesting seeing exactly where the tradeoffs are.

While I’d say Kagi pretty much universally returns better results for technical information or things like recipes where it deprioritizes search spam, it’s also pretty clear that there are other areas where the absence of targeting hurts results. Any type of localized results, e.g., searching for nearby restaurants or other businesses tends to be really hit or miss and I tend to fall back to Google there.

Of course, that’s because Kagi is avoiding targeting to the point where they don’t even use your general location to prioritize results. It’s an interesting balancing act and I’m not quite sure they’ve hit the sweet spot yet, at least for me personally, but I like the overall mission and the results for most searches so I’m happy with the overall experience currently.

Searches are supposed to be fast at giving you the answer you’re looking for. But that is antithetical to advertising.

And we have evidence that this is exactly why it happened, too:

https://www.wheresyoured.at/the-men-who-killed-google/

While I’d highly recommend giving either the article a read or the companion podcast a listen because Ed Zitron did some fantastic reporting on this, the tl;dr is that a couple of years ago, there was direct conflict between the search and advertising wings of Google over search query metrics.

The advertising teams wanted the metrics to go up to help juice ad numbers. The search team rightly understood that there were plenty of ways they could do so, but that it would make for a worse user experience. The advertising team won.

The head of the advertising team during this was a man named Prabhakar Raghavan. Roughly a year later, he became the head of Google Search. And the timing of all this lines up with when people started noting Google just getting worse and worse to actually use.

Oh, and the icing on the cake? Raghavan’s previous job? Head of Yahoo Search just before that business cratered to the point that Yahoo decided to just become a bing frontend.

Zitron is fond of saying that these people have names and it’s important that we know who’s making the decisions that are actively making the world of tech worse for everyone; I tend to agree.

Tree nested communication is much more superior than traditional thread based communication

Heavily depends, IMO.

Nested threads are great temporary discussion of a specific story or idea. They’re absolutely miserable for long-running discussions. New posts get lost in the tree and information ends up scattered across multiple threads as a result.

It’s also been my personal experience that the nested threads format just doesn’t seem to build communities in the same way forums did. I have real-life friendships that were made on forums decades ago and I never had that experience with reddit despite being a very early user.

I don’t think that’s entirely due to the ephemeral format, but I do think it plays a part in it. A deep thread between two people on Reddit might last a few hours and a dozen replies before it falls off the page. On forums threads running months or years were pretty common, and that kind of engagement with the same people certainly changes how your relationships develop with them.

Canoo is supposedly going to make a pickup based on their electric van platform that looks really interesting:

The expanding bed is an absolutely killer feature IMO. Small footprint the vast majority of the time but expands out large enough to fit a 4x8 sheet of plywood when you need that. All the fold-out workbenches are a really cool touch too.

The whole thing feels like the Kei trucks people in other comments are mentioning but upsized and up-powered to be more feasible on US roads.
