MoltenMan··on Willingness to look stupid
While I don't necessarily disagree with this, I also wonder how much his 'data' about Nobel Prize winners and Institute of Princeton grads actually holds up vs how much of it is just very expected regression to the mean. He talks about Shannon; at some point Shannon was always going to have his last great idea. Given that the idea that made him famous was his greatest, you wouldn't expect many other ideas like that just from normal variation.

Essentially, if you take scientific ideas, including Nobel Prize ideas, and put them all on a bell curve of how difficult it is to find them, you wouldn't expect the same person to have multiple ideas all the way on the right, even if they are very above average.

I think this makes sense as part of the existing 'skeptic cost'
MoltenMan··on Banned in California
Ok, but if you are investing capital in some sort of production line or industrialization you are not going to want to do that in an area where you might just lose your entire investment instantly; instead, you're just going to invest it in Texas or China. Of course with more extreme examples like yours you do have to put some cost on the existing companies to get it fixed, but it would be something with a smaller cost like having to dispose of the mercury properly (whereas in this article's examples they just flat out ban these things, which you can't do to existing factories).
MoltenMan··on The Age Verification Trap: Verifying age undermines everyone's data protection
As somebody who is entirely for restrictions on internet / social media, I think you're missing the bigger picture here. First, you assume that parents have the technical knowhow to restrict their kids from specific sites. My parents used a lot of different tools when I was a kid, but between figuring out passwords, putting my fingerprint onto my mom's phone, and spoofing mac addresses, I always found a way around the restrictions so I could stay up later.

But let's assume the majority of parents can actually do this. The problem with social media is not an individual one! We've fallen into a Nash Equilibrium, a game theory trap where we all defect and use our phones. If you don't have a phone or social media nowadays you will have much more trouble socializing than those who do, even though everyone would be better off if nobody used phones. As a teenager, you don't want to be the only one without a phone or social media. And so I truly do think the only solution is with higher level coordination.

Now, it's possible that the government isn't the right organization to enforce this coordination. Unfortunately, we don't really have any other forms of community that work for this. People already get mad at HOA's for making them trim their lawn; imagine an HOA for blocking social media! I do think the idea of a community doing this would be great though, assuming (obviously) that it was easy to move on and out of, as well as local. This would also help adults!

So to be honest, I don't think parents have the individual power to fix this, even with their kids.

MoltenMan··on Faster Than Dijkstra?
Most of this is very true, except for the one caveat I'll point out that a space complexity O(P(n)) for some function P implies at least a O(cubedroot(P(n))) time complexity, but many algorithms don't have high space complexity. If you have a constant space complexity this doesn't factor in to time complexity at all. Some examples would be exponentiation by squaring, miller-rabin primality testing, pollard-rho factorization, etc.

Of course if you include the log(n) bits required just to store n, then sure you can factor in the log of the cubed root of n in the time complexity, but that's just log(n) / 3, so the cubed root doesn't matter here either.

MoltenMan··on What's up with all those equals signs anyway?
This seems like the most likely reason to me!

I don't think this post reads as AI at all. It has none of the tell-tale signs either (em dashes, common constructions like 'not just ____ but ____, bullet points, headers, etc.)
MoltenMan··on Microsoft gave FBI set of BitLocker encryption keys to unlock suspects' laptops
> Right, so the solution is to silently upload their encryption keys to Microsoft's servers without telling them? If users don't understand encryption, they certainly don't understand they've just handed their keys to a third party subject to government data requests.

What exactly are you hoping Windows does here? Anyone who knows anything about Bitlocker knows Microsoft has the keys (that's where you get the key when you need it, which I have needed it many times because I dual boot!) Microsoft could put a big screen on install saying 'we have your encryption keys!' — would this change literally anything? They would need to also explain what that means and what bitlocker is. And then after all of that, the only people who are going to decide 'actually I want to set up FDE myself' are going to be the technical people who already knew all of this already! This is just a non-issue.

> This is such transparent fear-mongering. How often does this actually happen versus how often are cloud providers breached or served with legal requests? You're solving a hypothetical edge case by creating an actual security vulnerability.

This is not fear mongering at all! The nice thing about Bitlocker is that you don't need to put in your key 99% of the time (and in fact 99% of Windows users — who are not technical! — don't even know they have Bitlocker). But occasionally you do need to put it in. Once or twice I've booted to the bitlocker screen and I actually don't even know why. Maybe my TPM got wiped somehow? Maybe my computer shut down in a really weird way? But it happens enough that it's clearly necessary! That big Crowdstrike screwup a year ago; one of the ways to fix it required having your Bitlocker key!

> Encryption by default and cloud key escrow are separate decisions. You can have one without the other. The fact that Microsoft chose both doesn't make the second one necessary, it makes it convenient for Microsoft.

Again, this is not true for a product like Windows where 99% of users are not technical. Remember, Bitlocker does not require your key on startup the vast majority the time! However, there is a chance that you will need the key at some point or you will be locked out of you data permanently. Where should Microsoft give the user the key? Should they say on install 'hey, write this down and don't lose it!' Any solution relying on the user is obviously a recipe for disaster. But again, let me remind you that encryption by default is important because you don't want any old random laptop thief to get access to your chrome account! So yes, I think Microsoft made the best and only choice here.

MoltenMan··on Microsoft gave FBI set of BitLocker encryption keys to unlock suspects' laptops
> And because of Bitlocker, their encryption is worth nothing in the end.

No, it's worth exactly what it's meant for: in case your laptop gets stolen!

> flawed default

Look, in terms of flaws I would argue 'the government can for legal reasons request the key to decrypt my laptop' is pretty low down there. Again, we're dealing with the general populace here; if it's a choice between them getting locked out of their computer completely vs the government being able to decrypt their laptop this is clearly the better option. Those who actually care about privacy will setup FDE themselves, and everyone else gets safety in case their laptop gets stolen.

MoltenMan··on Microsoft gave FBI set of BitLocker encryption keys to unlock suspects' laptops
Just to be clear: bitlocker is NOT encrypting with your login password! I could be a little fuzzy on the details but I believe how it works is that your TPM (Trusted Platform Module) is able to decrypt your laptop, but will only do so if there is a fully signed and trusted boot chain, so if somebody gains access to your laptop and attempts to boot into anything other than Windows, it will ask for the bitlocker key because the TPM won't play ball.

The important bit here is that ~*nobody* who is using Windows cares about encryption or even knows what it is! This is all on by default, which is a good thing, but also means that yes, of course Microsoft has to store the keys, because otherwise a regular user will happen to mess around with their bios one day and accidentally lock themselves permanently out of their computer.

If you want regular FDE without giving Microsoft the key you can go ahead and do it fairly easily! But realistically if the people in these cases were using Linux or something instead the police wouldn't have needed an encryption key because they would never have encrypted their laptop in the first place.

MoltenMan··on Microsoft gave FBI set of BitLocker encryption keys to unlock suspects' laptops
I think most people don't understand that 99% of people don't know what data encryption is and definitely don't care about it. If it weren't for Bitlocker, their laptops wouldn't be encrypted at all! And of course if your software (Windows) encrypts by default but you don't want to bother the average user with the details (because they don't know anything about this or care about it) you will need to store the key in case they need it.

To everyone saying 'time to use Linux!'; recognize that if these people were using Linux, their laptops wouldn't be encrypted at all!

MoltenMan··on Claude is good at assembling blocks, but still falls apart at creating them
I agree with a lot of what you've said, but I completely disagree that LLM's are no longer sycophantic. GPT-5 is definitely still very sycophantic, 'You're absolutely right!' still happens, etc. It's true it happens far less in a pure coding context (Claude Code / Codex) but I suspect only because of the system prompts, and those tools are by far in the minority of LLM usage.

I think it's enlightening to open up ChatGPT on the web with no custom instructions and just send a regular request and see the way it responds.

MoltenMan··on Every country should set 16 as the minimum age for social media accounts
Whenever this comes up people point out, 'Come on, let parents decide for their kids!' -- I sympathize with this argument, but let me explain why I don't believe that actually fixes the real problem. For reference, I'm gen-Z, COVID hit while I was in highschool, and I have seen and to this day see Tiktok / Reels / Shorts used every day by my friends (and to some extent me).

I may not be having kids for a while yet, but if I had teenagers today I would absolutely move somewhere where it is not legal for kids to have social media accounts. The underlying problem is that this isn't an individual problem, it's a social one! If a teenager's friends all have social media, he is going to be left out! It is going to severely hurt his life. Even if he never watches short-form video (the main component of social media I think is detrimental), his friends will! When I was in highschool sometimes my friends and I would get together and we would be bored, have no clue what to do. Instead of messing around doing random things, a couple of them would just open up Instagram reels and bam, afternoon wasted. If the half the group isn't trying to do something, you aren't going to do anything. Contrast this with before I was a teenager and before phones, I vividly remember me and my friends just exploring and doing random things. It's just a different experience and I think social media needs to be banned for everyone for it to be effective.

MoltenMan··on The College Backlash Is a Mirage
I haven't looked at the source but the first paragraph of the article shows the percentage of people thinking a college education is important or worth it declining in the last decade. This is what I was referring to, but to be fair I don't know if college has actually gotten worse or if it's solely a change in what people think. For me personally it definitely is not useful at all for learning.
MoltenMan··on The College Backlash Is a Mirage
I think 'mirage' is the wrong word; college very much has gone out of vogue as a place of learning. But if you want to get a good job, you still do need to go to get the piece of paper, regardless of whether you think you'll be learning anything. The other factor you have to keep in mind is that college is where every 'smart' 20ish yo goes. If you want to meet people your age similar to you they are most likely all in college! It's difficult as a 20ish yo to have a social life outside of college.

I personally took a gap year working at a startup mid college, and as much as I enjoyed working I still ended up coming back to college purely for those two reasons.

MoltenMan··on Say No to Palantir in the NHS
I can't say I understand the Palantir hate. Isn't it just a database analytics SaaS? Why not hate Google as well because government employees who do things you don't like use Google? Is the Palantir hate just manufactured pointless rage or is there an actual reason behind it?

Sorry for being so aggressive. I suppose I'm just very confused at where you're coming from.
MoltenMan··on C/C++ Embedded Files (2013)
...what? What are you talking about? In what world would a compiler implement a preprocessor directive to ever use an llm, the internet, or your credit card details (from where would it get those)??? There are always implementation defined things in every language, for example, ub behavior. Do you get worried that someone will steal your bitcoin every time you use after free? Of course not! Even in Python when you OOM -- at least in CPython -- you crash with undefined behavior.
MoltenMan··on HyperRogue – A non-Euclidean roguelike
Good point, the movement is more isomorphic with a fully spherical 2D geometry game than I was thinking. But I still wouldn't say it qualifies as non-euclidean in the same sense as hyperrogue at all, given that you aren't fully stuck on a sphere (and they don't give any way to change the view to a top down 2D spherical geometry view; because it's actually just a regular 3D game).

More relevantly to your original comment, it is always going to be far easier to understand 2D spherical geometry (possible to create in 3 dimensions, we see it every day) than 2D hyperbolic geometry (not possible to create in 3 dimensions, completely foreign to us), so I don't think it is a 'display' issue at all.

MoltenMan··on HyperRogue – A non-Euclidean roguelike
Actually highly recommend this game. I got a lot of fun out of it when I discovered it a few years back, and it especially works well as an airplane time waster game. I'm not generally one for roguelikes but this one really is incredibly fun.

You can buy it on steam too if you want to support the developer!

MoltenMan··on HyperRogue – A non-Euclidean roguelike
Super Mario Galaxy is not non- euclidean; it's just a regular 3D projection onto a 2D screen. The spheres you travel on are technically non-euclidean if you consider the surface in a vacuum, but you aren't playing on the surface, you're playing in a full 3D space.

Additionally, 2D sphere surfaces are very understandable because they can actually exist in our 3D world and we're used to them; hyperrogue has a hyperbolic non-euclidean 2D geometry which is impossible in real life, much more confusing, and impossible to display with no confusion. I don't know what Smart Kobold is, but I presume it's also not just a regular 3D game like Super Mario Galaxy.

> You just wrote a whole bunch of paragraphs talking about how appearances made you feel things without ever addressing the actual facts.

Yes, appearances matter! That's why Trump is president right now (a fact, in case it isn't clear, I'm not happy about)! Because the American people were unhappy with the status quo. Whether or not you think DEI is "fair". And when people like you ignore this, you alienate the voting class, which you need on your side!

> Except there are DEI initiatives that look at every level.

No, there are not DEI initiatives for pre kindergarten / very early school. Not that I've heard of at least, and definitely not on a large scale. And I'm not even talking about adding DEI there; I'm simply saying that we should really be asking why the gap between men and women in STEM seems to start so young (and if it really is because of something that hurts girls, remove that. Which would still not be DEI!)

> Being in favor of the status quo is pretty easy, I admit, and hey, if you happen to benefit disproportionately from the status quo, bonus, right?

...what? I am arguing against the current status quo. And it's true, it would be beneficial to me for DEI to be removed / identity politics abolished. I also believe it would be beneficial to everyone (albeit to a lesser extent), but that's beyond the scope of this argument.

MoltenMan··on PSF has withdrawn $1.5M proposal to US Government grant program
Ack! There is nothing 'overly sensitive' about being annoyed when you see somebody else get an opportunity because of the color of their skin or gender. It's human nature! In fact I suspect the average person in favor of DEI and / or identity politics would still suffer a decent amount of cognitive dissonance if they were passed up because of something like this. Again, it's just human nature!

Please try to imagine advocating for women's rights 100 years ago and hearing somebody say something like 'overly sensitive women want to vote! Psh!' If you want to argue for DEI please try to present good faith arguments.

Personally, I don't really get butthurt about things, so this isn't a problem for me (although I do think it's a problem in general as it is obviously going to anger people). I do think one of the main problems with DEI is that it attempts to address the symptoms instead of the root cause of the problem. I.e. trying to get girls into stem / coding in highschool or college instead of figuring out why they're less interested in it from a much younger age (and if that's even a problem; classic nature vs nurture problem).

MoltenMan··on PSF has withdrawn $1.5M proposal to US Government grant program
I feel like you're glossing over my main point, which is that this stuff 100% does breed resentment for the average person, which is how we end up with people like Trump (obviously there are many more factors to consider but this is definitely one of them).

The difference between your scenario is just how visible it is; I have never ever had somebody go up to me and say 'This opportunity is being given to you because you're a white male'! If anything, it's the opposite! Did you know I was not eligible _to apply_ for a single scholarship for college a few years back, solely based on my race and gender? It was pretty demoralizing!

Again, I'm not saying that I _haven't_ benefitted from being a white male in some indescribable unknown way; but unlike in your scenario, I cannot _see_ this. Think about the average person, who goes their whole life seeing others being handed stuff specifically because of their race and gender and when they complain about it they simply get told 'Do you have no empathy? Your life is much better off than theirs!'

Again, who knows what the right solution is. But I don't think that it's the status quo.

MoltenMan··on PSF has withdrawn $1.5M proposal to US Government grant program
Maybe I wasn't clear in my previous comment about what exactly rubs me the wrong way, so here's an analogy: imagine you went to school and the the teacher lined everyone up by gender and handed out a cookie to everyone. And then she handed out two extra cookies to all of the girls! You would be annoyed! Does it matter that back at home guys normally get 4 extra cookies every day? No, because as a guy, you don't see or know this! (In this world brothers don't have sisters and vice versa). And even if you do technically know this because you've heard about it, you don't really viscerally understand it because it's not really your lived in experience.

So what is the solution? I can't say I know. But I do know that these things very much breed discontentment and it is at the very least important to recognize why.
