Their analysis about lead relies on a single study by Reyes. Far from robust. Additionally, if lead results in more violent people, then it's no wonder that reducing the births of people in lead polluted environments would have an effect on crime. What they would need to do to tease our lead, would be to find places with no to little lead pollution and show that abortions resulted in lower crime, which they do not seem to do.

Studies by Mielke and Zahran (2012), and Feigenbaum and Muller (2016) provide further evidence that lead is the main culprit in crime reduction.

Lead seems to be the reason, not abortion rates. Levitt and Donohue don't engage seriously with the Lead hypothesis as there are many compelling studies supporting Lead. They only engage with the weakest research. I'm not impressed. I worry that Levitt and Donohue are just adding wood to racist fires and their work will be used by bigots, fascists, and racists around the world. It's irresponsible work.

I think tripe is the only use an industrial abattoir would have for the stomach and that's likely to be handled by a human. My guess is that they have a bucket or something that they put foreign material into.

Hmmm, but I wasn't thinking of pet food: that would probably be ground.

Nah, this is nothing new.

We've solved this for ages with "snapshots" or "archives", or fancy indexing strategies, or just a freaking "timestamp" column in your tables.
> Better question to ask: Are current EV companies even properly recycling the batteries?

Tesla has set this up, but hasn't recycled many batteries yet since they mostly get second lives in at home "power walls" (which I guess, is why the started up that business?). We have another 5-10 years before those batteries start needing to be recycled.
For Kerberos, I was a minor foot soldier in the Crypto Wars.

Back in the mid 90s, Kerberos was restricted from export due to ITAR regulations (I had thought ITAR was obsolete, but just this year we had trouble purchasing some hardware in the USA due to ITAR restrictions).

Since IIRC Kerberos could be downloaded from MIT it's not clear how well these restrictions worked.

Nevertheless John Gilmore and I (maybe proposed by another of the Cypherpunks?) decided that we should get an ITAR-legal version of Kerberos in global circulation.

Before I ever left or contacted anyone about this a policy lawyer blessed it, and even talked about it with some people from the Commerce Dept, so everything was legal and above board. I'm pretty sure NSA knew about it too (this was back when NSA took Information Assurance seriously -- I think back then it might even have been a whole directorate).

The first step was to make a version with all the encryption stubbed out. That "worked" in that two copies of this code would connect to each other etc...with all communication in the clear with no encryption at all and no pretend-encrypted anything either. I think it was OK to take a password and copy it into another buffer and then send the contents to the other side of the connection, but honestly I don't remember and actually (see below) don't know.

I then went to Switzerland where I arranged for a local cryptographer to take our neutered code and make it compliant with the published papers on Kerberos. At that time I knew nothing about Kerberos's encryption and hadn't even look at source (neutered or original) so I wasn't even accidentally "exporting" anything in my head and could be sure I couldn't say anything to make the work easier. It was literally "can you make this package work as described in the literature".

After they got it working they connected to some sites in the US and all worked properly. And then we "imported" the swiss version and put it on our FTP server at Cygnus (Cygnus paid all the bills too) for other US people to use. Now there was a single copy of the source that could be used to protect people anywhere. Until then, even US companies couldn't use it to communicate with overseas divisions, even ones staffed entirely by US persons.
I wondered previously how feasible would it be to manufacture digital camera sensors with modified color filter mosaic, so instead of usual Bayer RGBG you would have RGB+589nm mosaic.

State-wide laws don't help you much when Jackson Hole, Tahoe, Deer Valley, and Aspen are all in different states (and Whistler and Mont Tremblant are nearby in another country).

Are skiers visiting Aspen primarily from within Colorado or outside? The ones who have to fly in anyway, they can pretty easily fly into a different resort that gives them the resort experience rather than the "packed into hotels" experience.

(For me personally, I gave a massive sad sign when I saw this on the homepage. I really liked him a lot for a few reasons: He did his thinking in isolation, for a long period of time walking around the Scottish highlands . He was a keen disciple of interdisciplinary thought being pivotal to innovation. He appears to have imagined things and thought about things in a pretty weird way for his time, although that might seem obvious, how well he grappled with the reality of weirdness is exemplary. 힝)
I'm amazed that the patent hasn't expired yet. I was sure I heard of this more than 20 years ago.
You might be forgetting the decade of crappy compact fluorescent bulbs before reasonably-priced decent-quality LED bulbs became viable. Crappy, in that I don't think I ever owned one that lasted anywhere near their supposed 10-year life. And the long warm-up time for at least some models, but you didn't know which ones. And how to dispose of them properly. And the concerns with mercury when you broke one.
Users can opt out of the Privacy Sandbox features if they know they are there and they understand the options, IMV the settings for this are unclear at best almost to the point of being misleading.

We all know the power of defaults which is why users have to opt-out of participating in Topics rather than opting in.

The browser is supposed to be the users agent but for most people the Topics API isn’t acting in their interests. I suspect if you asked people whether they we happy for any site that asked to know the sorts of things they browsed the web for they’d say no.

As for 3rd-party cookies they should have been killed off long ago, the reason the death is delayed is because Google is primary an AdTech company and other adtech companies persuaded the UK competition authorities that Chrome killing them off without a suitable replacement would be anti-competitive hence misnamed ‘Privacy Sandbox APIs’

Apple has its own set of issues e.g. why can’t content blockers block in app ads but Apple’s issues are a separate conversation
Pardon the jargon. But it is a necessary addition to the vocabulary.

To evaluate if a feature is valuable, you could attach the value of the feature to past inferences and retrain a new model to check for improvement in performance.

But this “attach”-ing needs the feature value to be as of the time of the past inference.

You mean car lithium batteries. In general, lithium batteries recycling isn't as successful in general because most of them are so small (e.g. cell phone and laptop batteries).

If it saves your thumb, sure. If you're ripping a wet piece of wood, no thumb risk at all, then, yeah, not so great.

Realistically, I don't like the tech or the methodology at all. Battle bots had saws that would drop into the floor without damage, and pop back up even, also without damage, and that was decades ago. That's the right model, not "fuck up the saw".
Time-travel evals, nice.
Yep, I'm the same way. I wish I could since they seem more comfortable in some ways, but they just fall right out!
I have created a resource for the purpose of making Hamilton's stationary action transparent.

It is possible to go in all forward steps from F=ma to Hamilton's stationary action; that is what I present.

The path from F=ma to Hamilton's stationary action consists of two stages:
(1) Derivation of the work-energy theorem from F=ma
(2) Demonstration: when the conditions are such that the work-energy theorem holds good then Hamilton's stationary action will hold good also.

I recommend that you first absorb the presentation of the subset of Calculus of Variations that is applied in physics:
http://cleonis.nl/physics/phys256/calculus_variations.php

Discussion of Hamilton's stationary action:
http://cleonis.nl/physics/phys256/energy_position_equation.p...

These presentations are illustrated with interactive diagrams. Each diagram has one or more sliders for manipulation of the contents of the diagram. That way a single diagram can offer a range of cases/possibilities.

About my approach:
I think of Hamilton's stationary action as an engine with moving parts. To show how an engine works: construct a model out of translucent plastic, so that the student can see all the way inside, and see how all of the moving parts interconnect. My presentation is in that spirit.

I've subconsciously ruled out DMs - so thanks for pointing out.

That's said, GVBs announcement was mentioning lack of supervision/moderation, and they continue to use WhatsApp - so I don't think it was Twitter/X DMs but actual replies.

And yeah you can simply set who can reply for each post on X - e.g. only mentioned users, so for their announcements basically no one.

And while there's obviously a segment of X users that are the kind you imagine also trolls on 4chan - reporting posts/replies with racism/hate/etc usually results in their temporary or even permanent ban.

Why can't tech companies seem to keep this stuff to themselves? I mean, it's interesting and all, but it's an even bigger reminder that Cloudflare is an Mitm attack on the Internet, in order to have access to this data. And if they have that data, no one could possibly believe they aren't somehow monetizing it. Consider if we read the same post from Google or Facebook; it would not be as well recieved. When the Internet was still little, it was cute to read OkCupid's data blog but those days are long past,
especially after leaks about Uber's heaven view. The post by Sleep8 in the wake of the OpenAI drama was also poorly recieved.

Elon: In non-linear programming, there are the Kuhn-Tucker conditions. In that math there are some constraint qualifications (CQs). It is of some interest to know which CQs imply which others.

Okay: One of the CQs is the Kuhn-Tucker one. Another is Zangwill's. Are they independent or which implies the other?

As a grad student, I found a solution.

Elon, you are a rich guy, so, let's put some money on this. I'm not a rich guy (yet) so, let's keep the amount small, say, $1000 from me and $100,000 from you. Naw, let's be generous and fair, $1,000,000 from you. Okay! It will be the easiest $1000 you ever made, right???

My bet is, within a year, a trained neural network won't have a solution.
This can't be good right?
I think the article actually agrees with you, that their toxitiy is hostile to outsiders.

"This entails, for example, that even if toxicity does not seem to make people leave conversations, it could still be a factor that discourages them from joining them."

They also agree that the effects of the moderation impact the data set, and this is mentioned. That's part of why they tried to include many different sites which may have different policies and even so it's cited as a potential problem.

What, specifically, from the conclusions do you think is wrong?

I also think you are misunderstanding what the criteria is. It is not comments that cause someone to leave in that specific instance (something there's not data for anyways), but comments that are declared toxic according to a ML model where the idea is to find comments likely to repel others due to being rude or unreasoanable, regardless of the actual effect. This is kinda squishy and objectionable too, but not in the way that you're saying so I figured it was worth clarifying
Thanks, I really do try.
> Almost all real numbers are normal

Well if we're being picky then I'm going to point out that almost all real numbers cannot be written down.

Of the numbers we can write down in a reasonable way, the computable numbers, we've only proven a relative handful of them to be normal in any base, and barely any normal in all bases.

So if you have an arbitrary irrational number where you can ask if it's normal, then the answer is probably "we don't know, we haven't figured out a proof", rather than "almost certainly". Those overwhelming odds about "almost all real numbers" don't apply to your number, because your number is computable.

The "wasteful" infrared light turns out to have important health benefits. The same health benefits can be got from sunlight, but when indoor light was incandescent, people who couldn't get sunlight because they had to work all day would get at least some infrared from indoors lighting.
For those in the Bay Area, the Alameda County Sheriff’s Office puts on a similar event [1], albeit slightly less extreme, at their regional training facility. Part of the day is spent in a crown Vic with slicks on a skid-pan (smooth concrete with sprinklers) learning how to recover from oversteer, loss of control, etc. I took my kid after he got his license since snow filled empty parking lots are pretty hard to come by around here. I can’t recommend it enough for new-drivers, or those who didn’t learn to drive in snowy/rainy areas.

> EVOC: Emergency Vehicle Operations Course is designed to instruct civilians in good defensive driving tactics. This course is also good pretraining for anyone who is going to be entering a police academy and wishes to learn some of the techniques which will be taught. Heavy emphasis is placed on skid recovery, loss of control recovery, control during a blowout, and operating on less than ideal surfaces. The students will demonstrate a working knowledge of driver skills by successfully driving such courses as the Skid Pan, the Hazard Avoidance Simulator, Threshold/ABS Braking Simulator, and other various skill and precision oriented activities.
It was some offbrand I bought from radioshack back in the day. Teflon tip, aluminum tube with a spring in it and an o-ring. Super simple, cheap.

The big thing is to get the tip more or less touching the solder you're looking to suck, and if you're on a PCB, make sure you allow it to cool between sucking sessions so you don't lift a pad.

Infrastructure side, probably quite a few already. On the product side Google does often hold promotions until the project demonstrates impact. What is likely to happen is that if the project succeeds everyone will get promoted.

Of course not. Long frames are totally valid.
I'm sorry, but this is a bizarre take to me. I don't care what happens to a saw if it would have otherwise cut my finger off.
Yeah, because people are foolish and disregard safety procedures. I don't think we can, or should even try to, structure society to keep people safe when they choose to disregard safety.
Which one created by human? hcaptcha
why is this so difficult to solve?
I have a feeling these will be as ineffective. From SawStop FAQ:

"You can operate the saw in Bypass Mode which deactivates the safety system’s braking feature, allowing you to cut aluminum, very wet/green wood (see above) and other known conductive materials. If you are unsure whether the material you need to cut is conductive, you can make test cuts using Bypass Mode to determine if it will activate the safety system’s brake."

https://www.sawstop.com/why-sawstop/faqs/

The first thing people will do is turn on the bypass and never turn it off.

This is an uncomfortable and divisive topic, and as such, shrouds rationality. For instance, if you believe that the subject of this matter is morally wrong, then you should rationally also be able to fully accept evidence that your particular beliefs lead to a negative outcome. If you are both arguing about the outcome of your beliefs, and unwilling to change them with evidence, then you’re either holding a rationally delusional belief, or engaging in deception to trick rational thinkers into adopting your morals. Let’s just be honest about why you are arguing for or against an analytical result.

I’m not saying that their study conclusions are correct; I’m just saying that acceptance or rejection of the claim should not be related to moral beliefs. It is, in my understanding of most religions, a pillar of faith to accept negative outcomes in adherence to scripture. It is easier, I think, to accept the self-flagellation form of this edict, than to accept burden onto others, and in this case, a wide social effect that seems incongruent with the aspirations of the faith itself. If they are right, are you wrong? That’s your burden.

I want to be clear that I am not taking a universal stance on the topic nor the analysis, nor religion. My personal experiences related to these topics are moderately severe, and it would probably not be productive to bring that here.
We absolutely hammered the MI50 in internal testing for ages. Was solid as far as I can tell.

Rocm is sensitive to matching kernel version to driver version to userspace version. Staying very much on the kernel version from a official release and using the corresponding driver is drastically more robust than optimistically mixing different components. In particular, rocm is released and tested as one large blob, and running that large blob on a slightly different kernel version can go very badly. Mixing things from GitHub with things from your package manager is also optimistic.

Imagine it as huge ball of code where cross version compatibility of pieces is totally untested.
I've seen jointer near-miss videos and the adult education woodworking class I took is even more terrifying in retrospect. I knew table saws were dangerous and assumed they were the most dangerous. At least with a table saw the fingers can often be reattached. Jointers and router tables just make hamburger.

I'm becoming a much bigger fan of mounting an uneven piece of wood to plywood and running it through the table saw to get that first edge.
He gives me a similar feeling to say, SBF did prior to the FTX collapse. This isn't to say he's a scammer like SBF, but rather that he has a similar hard to describe 'dishonest' air around him, where I feel he's deliberately trying to make himself seem smarter than he is for the sake of the attention alone, which makes me distrustful of him. I'm not really sure how to describe the feeling besides "attention-seeking charismatic fakes/frauds", but as another example, Bill Nye also gives me the same feeling.

His X shenanigans don't help either, where he has a reputation of engagement farming by posting dumb somewhat condescending "but akschually" type comments on things people are enjoying. Eg, when the last American total solar eclipse happened in 2017, he posted something along the lines of "ignore people when they tell you eclipses are rare", it's technically correct that eclipses happen fairly often, but he obviously had to know that what makes them exciting is that they're rare for the location the viewers are at. It's become somewhat of a meme to call someone NDT when they're being a buzzkill.
