I don’t think there are usually any bacteria in your blood

Yeah, I think that’s right, but where your clients are is irrelevant. That’s what confused me about the author’s statement.

I believe most (all?) registrars should let you give them a global DNS server, at which point your domain should be resolvable globally. Whether it’s reachable isn’t at the registration level, it’s at the DNS level. The blog author’s comment confuses me. Maybe they mean like having a TLD that matches each country with users? Seems not worth it.

You can get a domain for like $10 a year from many places. The national registrar I looked up was like $7 a year (Brazil).

Generally ML models are trained once and then used in their trained state unchanging. They don’t continue to learn.

I went down a slight rabbit hole on this. As far as i can tell (looking at manufacturer claims on their website for devices of the era), 2018 is right on the edge of when a lane finding algorithm would have started to incorporate ML techniques. That’s when mobileye released the eyeq4, which claimed to run ML models, and Wikipedia says was used by Ford, BMW, Nissan, VW, and Honda, albeit on only some of their models. The previous Eyeq3 from 2014 seems to be more classical models, but still used some ML techniques, seemingly more for things like speed limit reading.

ML algorithms refer to quite a wide variety of approaches. Generally what separates them is when the parameters of a generic model/algorithm are optimized over some specific data, instead of using an algorithm handcrafted to the particular problem.

I agree, I was trying to respond without getting too much in the weeds. The argument being made was that the entropy (information content) of the key itself is the problem. I was saying that isn’t true because entropy is defined differently.

But there is a lower bound for any algorithm who’s output produces something with a certain amount of information, and that’s the information->energy cost of that output. The specifics of the algorithm being irrelevant. I believe even with something like thermodynamically reversible computing you still pay the cost at the end for storing your result? (Which gets into one of the most mind blowing things I remember from stat mech about Szilard engines. Essentially that if I know the microstate of a system [or even a macrostate I believe?] I can slowly burn that information to extract energy from the system equal to the information I had)

You’re right that in the classical case with irreversible computation you can argue that there’s a thermodynamic impossibility to the brute forcing based on the Landauer limit.

I think you’re almost right about the high level principles, you’ve just forgotten that entropy scales as the log of the combinations not linearly.

So the entropy of a 128 bit key is not 2^128, it’s just 128 and therefore the fundamental limit on the cost required to recover it that you’re talking about is very small.

See landauer limit (which isn’t quite the same thing since it’s about irreversible computers which some quantum computers might not be, but gets at the idea of there being an energy cost to have information)

I believe the specifics of your thoughts about entropy of public vs private keys is also incorrect but not necessary to the core of what you’re saying.

There’s like two people’s devices behind my router. The amount of benefit I get to hiding which device is sending traffic is pretty meaningless. And all my user devices are using privacy extensions anyway.

I don’t quite understand what you’re trying to prevent. Like if I have an iot device that doesn’t support privacy extensions, who am I making the tracking harder for by using ipv4? Anything the device talks to already is probably tracking via the device authenticating in the first place. And anybody in the middle doesn’t really learn much by knowing that a particular device is sending opaque traffic vs the house is sending opaque traffic.

Big tech tracks us because we voluntarily login to their services. And they do so mainly to sell us ads. If you don’t want them tracking you, hiding IP doesn’t help much. Like don’t login to their services and block requests to their domains to prevent third party site integrations. If you need to use their services anyway, then you’re fundamentally screwed.

Something like this or this (don’t buy this one though, appears to be drop shipped or using product photos from elsewhere)? Or is that not square enough. I think the term in america is probably apron or overall dress.

I don’t think the burial matters. It’s not random atoms that are turned into C14. It’s specifically nitrogen. And I think those interactions mainly happen in the mid atmosphere with cosmic rays. So it’s the atmosphere providing the shielding.

The Wikipedia page for this explains it pretty well, especially the Physical and Chemical Details section.

I don’t think it’s that the plants are controlling the ratio. I think it’s that more C14 is being made all the time. And it only gets mixed into plants when they are living. Specifically it looks like C14 based CO2 is made in the atmosphere and then consumed by plants.

The vast majority of the volume of semen is made in the prostate and seminal vesicles (which are right next to the bladder), not the testes!

As a separate note, you definitely want to do testing/tuning with ironing disabled. It will hide a lot of the features/defects that you are trying to observe/tune away.

Once things are working you can then tune the ironing

Okay my new guess is moisture in the filament causing inconsistent extrusion, leading to the bubble on the surface. And also causing over extrusion.

For the walls, your picture is a bit too blurry/low res to really see, but I get the vibe of over extrusion with the small part that’s sticking up in the center of the perimeters in the lower right. Also the top of the anchors for the supports looked over extruded, with plastic kinda curling up at the top.

Your new print is now definitely under extruded with those gaps on the top surface.

I think flow rate is not the culprit here. Your bridges on the first print are also extremely suspicious. They should be solid lines, not the blobs you’re getting. Something is wrong with the flow of filament out of the nozzle. Could be moisture or temperature or issues with the extruder. It’s hard to tell.

Your non-infill regions also look very over extruded. I’d try printing 20mm cubes with a variety of flow rates and see what happens. If you’re using their profile, is it possible that the filament you have is larger than specified?

edit: looking a bit more, things seem really blobby too. Something is not right. Is it possible the temp is wrong for this filament? What is it?

To alkylate is to attach an alkyl group, which basically means attaching a saturated hydrocarbon chain to them, which is shown with the bendy things attached to the people in the image.

I think you’re thinking of alkal in the sense of alkaline, which is basic/high pH

If you want to create a space that propogates permissions, then you there isn’t a way to do that built into the spec. Because like the other person said, spaces are collections of rooms. They don’t control those rooms.

However, there are multiple bots written that can do something like what you want. Here for example. Essentially you make the bot the admin, and then only create rooms, etc, through it. And it will create things with the right permissions

Edit: This flexibility in space vs room permissions can also be seen as a cool thing in some ways. It allows you to do some things that wouldn’t be possible under Discord’s model. For example, maybe one room of a different community is really relevant to your community. You can directly include that room in your space and then all of the space members can see it and chat in it without joining the other community. Or you can even include their entire space inside your space.

The whole idea is that the quantum particle can’t have had the state you’re measuring all along. If it did, then measuring a particular set of outcomes would be improbable. If you run an experiment millions of times, you have a choice in how you do the final measurement each time. What you find with quantum particles is that the measurements of the two different particles are more correlated than they should be able to be if they had determined an answer (state) in advance.

You can resolve this 3 ways:

1: you got extremely unlucky with your choice of measurement in each experiment lining up with the hidden/fixed state of each particle in such a way as to screw with your results. If you do the experiment millions of times, the probability of this happening randomly can be made arbitrarily small. So then, the universe must be colluding to give you a non uniform distribution of hidden states that perfectly mess with your currently chosen experiment

2: the particles transfer information to each other faster than the speed of light

3: there is no hidden state that the particle has that determines how it will be measured in any particular experiment
