Apparently, BlackMeta is behind the DDoS attack to the Internet Archive. Apparently they are pro-Palestine hacktivists - their X account also has some russian written in it.
(Edit) Also, Internet Archive is banned on China since 2012 and Russia since 2015.

Me: What is isotony?
Bot: Isotony, a term coined by the mathematician and physicist Robert Hermann in the 1970s, refers to the property of a Lie algebra that ensures the commutator of any two elements is also an element of the algebra. In other words, isotony (or the isotonicity of the Lie bracket) means that the Lie algebra is closed under the commutator operation.
Formally, a Lie algebra G over a field k is said to be isotonic if for any u, v ∈ G, [u, v] ∈ G, where [ , ] denotes the Lie bracket (or commutator). This implies that the Lie algebra is a subset of itself under the commutator operation, making it a Lie subalgebra of itself.
Isotony has significant consequences in the theory of Lie algebras and their representations:
Cohomology: Isotony is a crucial condition for the development of Lie algebra cohomology, which studies the obstructions to extending Lie algebra homomorphisms. It ensures that the cohomology groups are well-defined.
Representations: The isotony property is essential for the classification of finite-dimensional representations of semisimple Lie algebras. It guarantees that the representation space remains unchanged under the commutator operation, facilitating the construction of higher-order tensors and invariant polynomials.
Geometry: In the context of differential geometry, isotonic Lie algebras are linked to the structure of geometric objects, such as tangent spaces and cotangent spaces. This relationship is exploited in the study of Lie groups, symplectic manifolds, and Poisson geometry.
Physics: In quantum mechanics and gauge theories, isotony is relevant to the definition of observables and their algebraic properties under commutation. The isotonicity of the Lie algebra of observables ensures that the commutator of any two observables remains an observable, which is vital for the consistency of the theory.
It's worth noting that not all Lie algebras are isotonic. For instance, the algebra of polynomial vector fields on ℝ² is not isotonic, since the commutator of two such fields may not be a polynomial vector field.
In summary, isotony is a fundamental property of Lie algebras that ensures their closure under the commutator operation. It has far-reaching implications for the classification of Lie algebras, their representations, cohomology, and connections to differential geometry and physics. Do you have any more questions about isotony or its applications?

Me: What is isotony?
Bot: "Isotonic" has different meanings depending on the context. Here are the most common ones:
- In Chemistry/Biology:
- Isotonic solutions: Refer to solutions that have the same osmotic pressure. This means they have the same concentration of solutes. Cells placed in an isotonic solution will neither shrink nor swell because there's no net movement of water across the cell membrane. This is important in biology and medicine, especially when administering fluids intravenously.
- In Exercise Physiology:
- Isotonic muscle contractions: Describe muscle contractions where the muscle changes length while maintaining a constant tension. There are two types:
- Concentric contractions: The muscle shortens as it contracts (e.g., lifting a weight).
- Eccentric contractions: The muscle lengthens as it contracts (e.g., lowering a weight).
- Other less common meanings:
- In music: Refers to equal tones or intervals.
- In mathematics: Can sometimes refer to functions that preserve order (though "order-preserving" or "monotone" are more common terms in this context).
To understand the specific meaning of "isotonic," it's essential to consider the context in which it's used.
Here are some examples to illustrate the different meanings:
- "The doctor administered an isotonic saline solution to the patient." (Chemistry/Biology)
- "Lifting a dumbbell is an example of an isotonic concentric contraction." (Exercise Physiology)
- "The two notes played an isotonic interval." (Music)
If you can provide more context about where you encountered the term "isotonic," I can help you pinpoint its specific meaning.

Both were given a mathematical space context before asking the question.
I didn't pay that much. It was 300 to 500 reais. I received the product in my doorstep.
Ebay or Aliexpress, I don't remember. It works in conjunction with "Livraria cultura", though.
Maybe the problem is not pornography and videogames, but a grim look at the future - where the person has no stimulus or sight of something good for themselves. Maybe if things were a little less darker and men believed in themselves and their future, things would be better.
It seems that the book focus on foreign wars and interventions, but the lasting impact of western culture industry in the whole world is also important. I think it also takes a better life experience out from the ordinary american citizen. The western american citizen could be living a better life (more independent and self-aware), were it not by mass culture.
I bought a Kobo Clara last year and it works. I can even buy books. I live in Brazil.
Incredible. How can companies have that much power? Buying a nuclear reactor as if it were a birthday gift.
Linux Mint is easier to use, you don't have to edit the sudoers file as well. Linux has limited marketshare because of its marketing. Companies aren't interested in a OS for PCs (personal computers). It doesn't need to be efficient or run well. They just care about keeping the agreements with Big Tech and that things work smoothly with one another (Microsoft working well in cloud/server/local) and that their enterprise software is running well. That goes along with close ties to Big Tech. Linux can reach major parts of the personal computer space, but it will need to do so without the help of Big Companies, which is a challenge.
It needs to work and be reliable, else it becomes something like YaCy, that doesn't work that well. Well, Mastodon and Lemmy work fine, so that's a first step.
What does this mean for Entropy? Is the Arrow of Time still always forward?
Yes, and there are people who already worked on terminal screens using RISC-V. But any compatibility advancement is already an advancement for backtracking how those systems work. Therefore, an advancement in Open Hardware. If we can use those systems more efficiently, it's all the better.
I think this kind of work is a good step towards Open Hardware.
Well, it is a little weird that Tor was originally a military technology funded by the US Department of Defense. Also, privacy in these days is really hard to achieve.
I have worked with somewhat large codebases before using LLMs. You can ask the LLM to point a specific problem and give it the context. I honestly don't see myself as capable without a LLM. And it is a good teacher. I learn much from using LLMs. No free advertisement for any of the suppliers here, but they are just useful.
You get access to information you can't find on any place of the Web. There is a large structural bad reaction to it, but it is useful.
(Edit) Also, I would like to add that people who said that questions won't be asked anymore seemingly never tried getting answers online in a discussion forum - people are viciously ill-tempered when answering.
With a LLM, you can just bother it endlessly and learn more about the world while you do it.
Dailymotion does not allow for commenting anymore. That's why I stopped using it.

Today I had to downgrade fastapi from 0.114.0 to 0.112.4 to make a software work. And it just hit me - what if pip didn't support 0.112.4 anymore? We would lose a good piece of software just because of that.
Of course, we can "freeze" the packages into an executable that will run for as long as the OS supports it. Which is a lot longer. But the executable is closed source. We can't see the code that is run from an executable.
Therefore, there is a need for an alternative to which we still have access to the packages even after the program is built. That would make it safely unnecessary for pip to store all versions of all packages forever more.
Any ideas?

Magic in monitored quantum circuits has an impact on classical simulability transitions that goes beyond entanglement; these transitions can be driven by the degree to which magic can spread within the system.
Last week I posted about the magic qualities of quantum systems in Computer Science. Now I bring an example article that makes use of it.

Why, instead of safely entering a BIOS setup, does the cell phone brick when installing the Custom ROM wrongly? Wouldn't this protection be better for users? I mean, this could be done through ADB.
Also, do you think it's possible that this way of doing things will come to the computer, with ARM hoping to gain a good share of the market and all?
