Even at military contracting prices, estimates put them at $100-200M each IIRC. That's not terrible.

The highly enriched fuel is used because it simplifies the design and maintenance. It eliminates all the machinery you'd need to support things like operational refueling of the reactor. Old designs still needed to be rebuilt every 25 years but the new ones are sealed systems that are never supposed to be cracked open over their design life.

I think the main reason we don't use HEU in civilian reactors is non-proliferation concerns, valid or not. Ideally you'd want maximally simple, sealed reactors for the same reason the US Navy does.

Thanks! I looked, but that's a segment about someone at Flock accusing anti-Flock people of being "antifa" or terrorists. I'm about as anti-Flock as I think it's possible to be (having been instrumental in killing it my Chicagoland suburb) and I'm not not sure what to do with "someone at Flock said something dumb".

In case it helps: my thing here is, the video we were commenting on thread seems to be about all public cameras, not just AI-assisted smart cameras or even security cameras more broadly. That was my complaint.

It's not that I don't think there's a video to do about 60 open Flock admin consoles; I'm sure there is. I'm just not sure what the implications are, because that video spent all its time talking about stuff that is trivially true of all public cameras, many of which are indexed on Google already, not through Google-dork searches for open console but instead with searches like "open IP camera live streams".

(I was struck by this in part because I vividly remember when Russia invaded Ukraine flipping between dozens of different live camera streams in places like Mariupol; that's obviously not the US, but you can do very similar stuff in the US, and on a lot more than 60 random misconfigured Flock cameras).

I think there may be something to the PTZ on the new Flock cameras that makes this worse? I just think he should make a better, sharper video case against them.

Thank you for giving me a link!

Plenty of real leather seats that have done the same. I had a 10 year old real leather Volkswagen that did the same myself.

Meanwhile, I have a 11 year old Vinyl “fake leather” car with no issues, and a 8 year old car with PU pleather that looks nearly brand new. Ironically, the steering wheel is made of real leather and has started flaking in a few small corners.

I’m not sure how any of those anecdotes proves which is more durable or long lasting than the other.

The most full stop, yes. But that's not surprising, is it? Since densely populated places disproportionately vote blue.

We need a better model. Platforms like LinkedIn and Instagram shouldn't own your content. They should just connect to your own personal website. I am building an open-source system where everyone hosts their own site and publishes everything there from short notes, long articles, photos, whatever you want. You can auto-cross-post to those big platforms to keep your reach (Buffer for personal sites), but your site stays the single source of truth.

Once enough people join, we can launch our own open feed that connects directly to the people you follow. No need for the big platforms at all. You pull updates straight from their sites in real time and move freely without losing your content or your audience. It reuses the network effects we already have while giving you true ownership and independence. This also helps people who want to escape feeds entirely: with a personal site, they can subscribe to a simple newsletter, delivered daily, weekly, or monthly with all the updates, so they stay connected without the endless scroll of social media.

Congress is likely to flip for many reasons. This is just a drop in the bucket. Places like Wyoming aren't on the table. Republicans are in a jam because nobody can challenge Trump without being primaried.

The real problem for Trump and Republicans is they do great when Trump himself is actually on the ticket. That's his power. Unfortunately for him, he will never be on a ticket ever again. But he still holds considerable influence over primary voters. Primary voters don't win marginal States. Trump is a paper tiger but because of his control over primaries Republicans are trapped.

Treating users like adults and allowing them full control over setting system capability and app launch restrictions on devices (and even implementing fully optional, widely blocking restrictions as "parental safety options") was the industry taking it seriously. You considering the freedom of choice to the user as disastrous and the lack of heavily restricted lockdowns by default as "refusal to take concerns seriously" is just a reflection on your attitudes about other people, not any real argument for improving privacy or safety. You ARE a morally panicked maniac if your only grossly offensive things you want to keep pretending are horrifying examples have absolutely nothing to do with the invasion of privacy of children and more to do with puritanical outrage on children accessing adult material.

Just to add my own observation here: some cuisines are really optimized for sharing in larger groups… certainly a lot of the regional Chinese cuisines assume many people at a table, with large (i.e. higher priced) servings. If it’s just 2 or 3 of you, you end up getting only 1 or 2 dishes, often with a lot left over.

So, this is a genius way of optimizing for that!

I totally want something like this here in Sydney.

You can pretty much do everything in Vivado from the command line as long as you know Tcl...

Also, modern Verilog (AKA Systemverilog) fixes a bunch of the issues you might have had. There isn't much advantage to VHDL these days unless perhaps you are in Europe or work in certain US defense companies.

Out-competing yields rewards for effort, that doesn't make it necessary. All that's necessary is maintaining. Many small businesses coast by for 30 years with no aspiration to do more.

Japan has had stagnant GDP growth for decades. Growth is not "necessary" as socialist like to project, it's just better. Productivity/innovation increases through growth have drastically improved our quality of life. Meanwhile socialists treat the world as zero-sum, as though everyone started out with a pile of cash which gets divvied up. Redistribution can be good, but you first need to generate the wealth.

> feels like a proper 21st century C language with Wirth's design ethos.

While Odin is a modern and capable language, it belongs to the "C-alternative" school (alongside Zig) rather than the "Wirthian" school (Pascal, Modula-2, Oberon). Odin, by design, retains manual memory management and allows pointer arithmetic. Oberon has a GC and very restricted pointer use. Odin's "joy" and "practicality" come from adding many features that Wirth would have considered "unnecessary complexity".

Definitely impressive as a proof of concept. A lot of the other problems can be solved with iteration. There are some IP67-rated drone motors meant to both fly and run underwater (available from Westmag for example).

There might be less that can be done about the underwater drag, but if it doesn't need to go long distances underwater that's not as much of a problem. For the RF signal, it can either run autonomously underwater, or use a fibre-optic umbilical, or even convert from an umbilical to wireless when it takes to the air.

I think it's more than fair to document that some implementations lie about their intentional violation of the spec, even if that violation is done to make the login process smoother.

Still, I've never seen a website try to block Bitwarden's passkey management (though I've had plenty of issues because of its partial implementation of the API, especially in early versions) despite its spec violations.

For some of the implementations, user verification is a massive pain (as browser extensions often only have long and complicated passwords to authenticate) but for KeepassXC a quick and simple fingerprint/facial scan is an option, as it already offers integration into the native OS biometrics anyway.

Also, don't forget that python has;

list = [
1,2,3,
[ 4, 5 ],
6
]

Without this Python would basically have to be Yaml-ish Lisp:

=
a
*
2
+
3
4

Let's drop the leading Yaml dashes needed to make ordered list elements. So we have an = node (assignment) which takes an a destination, and a * expression as the source operand. *'s operands are 2 and a + node, whose operands are 3 and 4.

Similar experience and timeline with codex, but tried it last week and it's gotten much better in the interim. Codex with 5.2 does a good job at catching (numerical) bugs that Opus misses. I've been comparing them and there's not a clear winner, GPT 5.2 misses things Opus finds and vice versa. But claude-code is still a much better experience and continues to just keep getting better but codex is following, just a few months behind.

My pet peeve is lazy "documentaries" where the uploader doesn't even bother to edit their input text. This results in a lot of weird verbal errors that you'd never hear from an actual human speaker. They instantly distract listeners from the content, so why even bother?

Cerebras and Groq both have their own novel chip designs. If they can scale and create a consumer friendly product that would be a great, but I believe their speeds are due to them having all of their chips networked together, in addition to design for LLM usage. AGI will likely happen at the data center level before we can get on-device performance equivalent to what we have access to today (affordably), but I would love to be wrong about that.

This picture is wrong because deaths themselves are not as interesting as estimated years of live lost.

For cancer and heart disease that multiplier would be around 5x (e.g. mostly older people die from cancer, but if they did not, in ~5 years (optimistically) they'd probably die from something else anyway). But for overdoses that would be around 50x. So one needs to scale overdoses at least 10x.

This just sounds like another security nightmare.

We're not in 1980 anymore. Most people need zero, and even power users need at most one or two apps that need that full access to the disk.

In macOS, for example, the sandbox and the file dialog already allow opening any file, bundle or folder on the disk. I haven't really come across any app that does better browsing than this dialog, but if there's any, it should be a special case. Funny enough, WhatsApp on iOS is an app that reimplements the photo browser, as a dark pattern to force users to either give full permission to photos or suffer.

The only time where the OS file dialog becomes limited is when a file is actually "multiple files". Which is 1) solvable by bundles or folders and 2) a symptom of developers not giving a shit about usability.

Have you considered that it's used as a unit to represent capacity of our power grid?

As in, we have now have the energy capacity for 300,000 fewer homes given this operating data center.

So not only is it a relatable unit, but it's an incredibly meaningful unit for those who care about ensuring that energy availability actually support something of value (families) rather than something wasteful (crypto mining).

There are thought experiments where the various Planck units (or, times some small power of pi or 2pi) pop out quite naturally.

The theoretical entropy for a Schwartzchild black hole is nicely expressed using the Planck area.

So…

No. Your assertion that they have no value in theory, is wrong.

(Also, like, angular momentum is quantized in multiples of hbar or hbar/2 or something like that.)

It may be true that they aren’t a good system of units for actual measurements, on account of the high uncertainty (especially for G).

But, there is a reason why it is common to use units where G=c=hbar=1 : it is quite convenient.

Could this be applicable and available to the public within a reasonable time horizon? My mother is dealing with a brain tumor located in the pons, and no surgeons will operate because of its location, as the risk is too high. Radiation treatments have also been exhausted and have already caused some necrosis. There was another form of light-based therapy, but it is experimental and carries an incredibly high risk as well. The prognosis has never been good, but we’ve been holding out hope. At this point, treatment consists of nonstop chemotherapy.

To folks who wax lyrical about FPGAs: why do they need a future?

I agree with another commenter: I think there are parallels to "the bitter lesson" here. There's little reason for specialized solutions when increasingly capable general-purpose platforms are getting faster, cheaper, and more energy efficient with every passing month. Another software engineering analogy is that you almost never need to write in assembly because higher-level languages are pretty amazing. Don't get me wrong, when you need assembly, you need assembly. But I'm not wishing for an assembly programming renaissance, because what would be the point of that?

FPGAs were a niche solution when they first came out, and they're arguably even more niche now. Most people don't need to learn about them and we don't need to make them ubiquitous and cheap.

I don't see where he is threatening anybody? He's just stating the obvious. If you promise to store a key in a non-exportable format and then create a big export button, websites won't trust your software.

> What happens if my PC goes down and I couldn't export my data? I just can't log in anywhere?

Then you follow the procedure you would follow for when you'd forget your password. Probably a password reset through email, maybe calling customer support. Or if you have it set up, you could use the passkey set up on your phone or Yubikey or whatever to log in and create a new password on your new PC.

Passkeys aren't passwords, that's the whole point. It's modelled after the "something you have" factor, not "something you know". If you're finding workarounds to violate the security design, you're not gaining any advantage by using passkeys. Just use a password if you want to use a password.

Yes, some cohorts are more useful than others for nation building, that's just reality, especially if excess mouths are net drains relative to national resource available. Too much excess and not just useless but actively detrimental to development. It's not saying time to purge, but excess demographics can dilute development resources too thin, double bad if above domestic carry capacity, i.e. getting import dependant trapped.

PRC averted 200-300m birth who would have spread family resources into developing country trap. The family planning exchange is non-existing 400m low skilled workers / subsistent farmers that is net drain on national power vs having 100m tertiary to uplift into developed country. All PRC rising in the last 20 years is because PRC family planning aborted a fuckload of 2nd/3rd/4th+ siblings so families can concentrate resources to get 1st kid into STEM. They speedrun the high skill human capita game, compressing 100s of years of human capita accumulation in 50. There's downsides, but they come after the up.

What's better for development, a 1.8B country of 6 Nigeria's and 2 Japans or 1.4B country of 2 Nigerias and 6 Japans. The latter. And you would recognize the former, while all lives are special blah blah blah is absolute developing shitshow. Every Nigeria PRC avoids is 200m of less governance overhead, i.e. make work jobs. AKA see which way India trended. Look at new gen of PRC protein consumption and average height vs alternative, stunted growth from malnutrition that literally makes significant % of population too stupid to integrate into modern economy. That's what happens, you can literally fuck up your human capita stock so much by diffusing limited resources that 100s of million become too biologically stupid to do modern jobs i.e. even in PRC, 100s of millions from old times too stunted and innumerate to do even basic factory work. PRC didn't abort enough.

> Still, I've never seen a website try to block Bitwarden's passkey management

Ideally it shouldn't be possible, or at least it should clearly be an ugly hack for a website to be doing something like this. Instead the spec authors explicitly endorse blocking clients that they feel are non-compliant. I'm not going to use a login spec that encourages websites to ban me because of the software I choose to use.

> for KeepassXC a quick and simple fingerprint/facial scan is an option, as it already offers integration into the native OS biometrics anyway.

Man don't get me started on the passkey environment's bizarre obsession with biometrics. My desktop computer doesn't have a fingerprint reader or a camera, and if my OS (Arch Linux) supports that junk I've certainly got no interest in doing the work to set it up just so I can log in to a website.

This was previously the location of an Alcoa aluminum smelter which used something around 1000+ MW. And that's why the crypto farm is there -- it already had sufficient electrical capacity to the site.

Folks should be happy since the crypto operation is using far less power and dumping less heat into the environment that the industrial operation that was previously there, but datacenters seem to be a trendy thing complain about at the moment so here we are.

> a famously hard to read language.

That's putting it lightly. Many jokes were made at Perl's expense on that topic, but

$\=$/;for(@ARGV){open F,$_;while(<F>){print if/$_/}}

is a valid Perl program to grep for lines that are the file's name. One of the jokes was that it was a write only language and it was only half way a joke. Coming back to a pile of magic variables months later with no comments, omfg. Meanwhile, Python sometimes scarcely even needs commenting if it's a short script if the writer uses descriptive function and variable names.

Perl's downfall, was that coming back to a ball of Perl mud after say 3 years and have to fix a bug, due to lack of classes and Perl 6 being delayed forever, you were in for not lot of fun. Python isn't perfect and that's why it's grown types, but Perl was seriously write only at times.
