I guess not much of a chance that February 23 or 24 will be "Square root 5 Day". Poor approximations.

Is it really such a great idea to post videos on YouTube that teach Redamsa and other hacking methods with explicit instructions?

Number of Numerical Magic Square , up to rotations, reflections, where rows, columns and diagonals add up to the same number :1 for 3x3, 880 for 4x4, 275,305,224 for 5x5, approximately 17,753,889,197,660,635,632 for 6x6. And we haven't even reached 10 x 10 yet. When I looked it up first, on my DuckDuckGo, I found Magic Squares for letters, supposedly used to invoque spirits to hurt someone. I tried one just out of curiosity, but my boss only told me he had a headache, and it rained for like a week straight. Edit: Last paragraph is a joke, of course.

I'm amazed by what I'm seeing on TikTok regarding advancements in Chinese robotics. Viewers are commenting that they think the robots are actually people in suits. That's how natural they are walking now.
They're not just walking. They can do anything and have passed the limitations of human movement. It's beyond parkour.

I can post the TikTok videos as I come across them here if you want, but I'm under the impression that TikTok posts are frowned upon here. The Chinese use TikTok as a social media platform to showcase their advancements. One Chinese start up company is offering these robots for the price of a smartphone.

The exponential speed of the advancements are shocking. We're talking a few months now instead of years.

I wish I was young so I can see it all happen, but I don't have long left unfortunately.

What a tease.

Blade Runner 'skin jobs' are right around the corner.

I first thought they would just make a synthetic human, but these robots will be super human.

If this tech got in the wrong hands, with rogue AI, I have no idea what might happen.

The future is very uncertain. I'm not just talking robotics. AI can make a virus can can kill mankind.

The world as we know it is about to change rapidly.

Obviously, we won't have synthetic humans in 12 months, but with each yearly quarter, AI will change the world.

Just be sure to use critical thinking when assessing robot advancement videos on TicTok, or any other social media platform for that matter. Check the source of the video. Check the source's sources to make sure it's all legit.

While this may be good advice about any subject, it especially applies to robotics videos lately. In my personal anecdotal experience, in my own social media feed lately, of all the videos lately that involve robots, nearly 100% of these videos are AI generated or just simply AI slop.

In other words, yes the robots look extremely natural and realistic, but that's just because AI video generation is getting so much better (there aren't even necessarily any real robots at all, in most of these videos).

Of the few (very few) videos that are real, most of them are made by the companies' marketing that portray the robot overly optimistically (probably).

That's not so say that there are no robot advancements. There are. There's plenty of actual, true advancements in humanoid robotics lately. I'm just saying that most of the videos circulating on social media mischaracterize these advancements.

This cardboard box has a little tab on the big tab that keeps the "lid" flap closed by fitting into a slot on the flap. The little flap helps you to pull the big tab out of the slot more easily when you want to open the box.

This reminded me of "servo tabs" on certain aircraft --- little tabs that the pilot's control actually operate, which then move the main control surfaces through their own aerodynamic forces.

You are correct. I’ve seen amazing videos years ago before AI video generators were capable of deceiving us. I’ll dig them up and probably start a new thread about it.

There are developments that are not being showcased that are amazing, but also quite worrying. They have made killing machines that make the Terminator T-500 look ridiculous. They’re keeping that arsenal under their hats.

China has an army that should not be trifled with.

This video is 16 years old.

This video showing high speed reactions is all very interesting but not what the adverage person needs .. We need robotic house servants , INDISTINGUISHABLE FROM HUMANS . not the clunking robot looking contraptions which are state of the art at present .... to pick our dirty laundry from the floor and put in the washing machine , wash the dishes, make our beds... they would move with the smoothness and grace of a human .

I was just imagining if a family purchased one of the currently available robots (like the G1 Unitree) as a house servant. It would have a learning AI that grew with the household and witnesed al the deaths and births. They could transfer the AI to an upgraded model and it will live with the family for decades until the upgrades became an actual synthetic human. If someone inherited the robot in their will, they could transfer the AI to another robot to give to another sibling.

That is actually almost possible now. It would make a good sci-fi movie.

In mathematics:

* The symbol **x** usually represents an **unknown** quantity or **variable** quantity.
Example:
( 2x + 3 = 7 )

So here, **x** has no fixed value until you solve for it.

---

In computer science / programming:

When you write something like:

```c
int x;
```

it means:

* **`int`** = data type (an integer type — whole numbers)
* **`x`** = the name of a variable (a named storage location in memory)

So this line says:

“Create a variable named `x` that can hold an integer value.”

But does it mean “unknown”?

Not really — at least, **not in the same way** as in math.

In programming:

* `x` is *a container* for data, not an unknown to solve.
* It might start out uninitialized (i.e., it doesn’t yet *contain* a known value), but it’s not “unknown” in the algebraic sense.

For example:

```c
int x; // declared, but has no value yet (uninitialized)
x = 5; // now x holds the integer 5
```

So while `x` might not have a *value yet*, it’s not an *unknown* to be solved — it’s just a variable ( name ) that will eventually store data.

If this is intended as a "random thought" - and yes, it does qualify as such - what's going on here is that the word "variable" means something different to mathematicians and computer programmers. That's not a problem with either the mathematicians or the software people, it's an example of how natural language naturally overload words.

I used to get pretty confused at the swap between the informal use of words in daily language and in the technical sense. Maybe we can choose a special font to go between the two. The term 'Likelihood' comes to mind here, used informally to mean the probability, and technically refers to something else.

And your IDE/Programming environment is like your autistic friend who can't use context to narrow down or discard different possible meanings. You may correctly write 1,000 lines of code and the 1,001 st line contains one mistake and the code will not run/compile.

No way. I can't count how many different fonts I have used throughout the years. I have \mathbb{}, \mathcal{}, \mathfrak{}, \mathrm{}, \mathbf{}, \mathscr{} on this keyboard alone, now add the fonts I downloaded (Sueterlin, Cyrillic, e.g.), Greek, and whatnot. Another font would only complicate things even further, and most of all, would be immediately and inevitably abused by mathematicians.

I meant a general font to separate the formal use of a fixed term to determine if it's used formally or informally.

Good luck with that, but chances of it sticking are virtually nil (if the past is any indication of the future). Language is chaotic and weird.

Just think of how kids* commandeered the use of the word literally, making it an emotive, sarcastic synonym of figuratively. "My head literally exploded when I heard the news about Jesse." The same fate would await the font.

I will try to find a way, irregardless ;).
Edit: I would use parentheses with my hands at times. Maybe there's some gesture that can be used to the effect of the distinction for/in speech.

Many legal documents do that. At the beginning of most of my insurance policies there is a section of definitions, stuff like “PERMITTED DRIVER means ….” and throughout the document the term is capitalized to indicate that that is exactly what is intended.

Don't we already have italic, cursive, all kinds of quotation marks, hyphen, semicolon, parentheses? What more do you need?

Maybe just that at least one of those is consistently used, implemented.

What I meant to convey is that languages change over time. Sure you can define your terms for a specific document (as @Nugatory points out above), but expanding usage outside of use specific documents with well defined terms (e.g., a glossary), the general usage of any given common language changes chaotically.

There is a trend of fewer new posts over the last decade, but I don't think this is because of AI.

No. Learning in STEM fields cannot be compared with studies like law, where mainly facts are important rather than their combinations, or with courses like anatomy. You can learn facts in mathematics or physics, but you won't understand them just by facts.

If it were possible for AI to do that there wouldn't be hundres/thousands of Annotator jobs in several areas.
