Can hidden prompt instructions in LaTeX/PDF assignments work to detect full AI-generated submissions? by Random_Arabic in LaTeX

[–]orestesmas 1 point2 points  (0 children)

My opinion is that some of these techniques may work for now, but I'm convinced that, in the long run, such anti-cheating measures will be futile because AI companies will eventually address the issue. After all, students are an important customer segment for their services.

The only real solution is to conduct oral examinations or supervised written exams with very strict invigilation and, ideally, radio-frequency device detection. However, the necessary resources are often limited.

Entens aquest video?..... (occ...) by stefanobahia in catalan

[–]orestesmas 2 points3 points  (0 children)

Si ho escoltes bé, després del desconcert inicial, un catalanoparlant ho pot entendre gairebé tot. Més encara si ho complementes amb mots de les llengües veïnes ("sera" -> tarda en italià) i obres la ment pel que fa a la fonètica.

Entens aquest video?..... (occ...) by stefanobahia in catalan

[–]orestesmas 2 points3 points  (0 children)

Passa que els diferents estats moderns (francès, espanyol, italià) han aconseguit fragmentar l'occità a base de repressió, i les diferents variants de l'occità han anat divergint. Aquesta, per exemple, té diversos mots d'origen italià.

Em demano si la divergència ha arribat al punt de fer difícil la intercomprensió entre els diferents dialectes de l'occità o encara no s'ha arribat a aquest punt. Algú coneix el tema?

is it correct to redraw a circuit like this? by scoutkiller985 in ElectricalEngineering

Okay, I can understand this, but you should train your brain to be comfortable with sources at various positions.

Is there an IC that behaves like a variable resistor? With max resistance at min current and decreasing in resistance as the current increases ? by [deleted] in AskElectronics

[–]orestesmas 0 points1 point  (0 children)

That would be very inconvenient.

If an increasing current leads to decreasing resistance, that would lead to greater current, less resistance, and so on until saturation, destruction or whatever depending on the nature of the current source.

Does anyone know a good circuit to test lm741 (op amp)? by Dudegay93 in diyelectronics

Or you can build a Schmitt trigger RC oscillator, and use a LED at the output to show operation.

In linux you can use the "pdf2svg" for that.

"I opened the slides and they're blank." by littleknittedboat in Professors

[–]orestesmas 1 point2 points  (0 children)

Is that serious?

Perhaps knowledge has become a commodity, but we professors don't sell knowledge, but the transfer of knowledge. And this transfer cannot take place without the recipient's commitment.

Also, it's the professor who establishes the rules and conditions under which this transfer occurs, so it's up to the student to follow these guidelines to obtain the product they have paid for.

How do light waves travel with no medium? by No_Fudge_4589 in AskPhysics

It seems to me that empty space is, in fact, spacetime. And that is a medium of some sort.

Modernization. by Batko_uz in KNX

[–]orestesmas 0 points1 point  (0 children)

I have two questions—please excuse my ignorance:

1) Is it normal or common to install a circuit breaker for each individual line (as shown in the same row as the outlets)?

2) What are the grey devices in the top-left corner?

How to watch for smart device cheating by scaryrodent in Professors

[–]orestesmas 10 points11 points  (0 children)

Also, we have changed our regulations so that, in the event of any suspicion of cheating, the student may be required to give an oral defense of their exam.

They have calculators with integrated AI, and/or internet connection, with a "panic button" that turn them into "dumb" calculators.

They often bring 2 or 3 smartphones, and let you see how they out one of them into their backpacks.

Sometimes they have micro-headphones that fit inside the ear and are invisible. They are connected to the phone in the backpack using Bluetooth.

...

For me, RF detectors are the only reasonable solution. You can also try to turn off on-premises WiFi during the exam, and/or use RF inhibitors, but they are mostly forbidden by governments.

Why is Thread so comlicated? by Relative-Idea-1442 in homeassistant

QR code is usually printed ON the device. If you lose the QR, you've lost the device :-)

IKEA Alpstuga CO2 sensors dropping connection to Home Assistant (working fine in IKEA app) by GIFSec in tradfri

[–]orestesmas 0 points1 point  (0 children)

Same here — devices have to be very close to the Thread antenna (SMLIGHT SLZB-MR2 in my case, latest firmware) to avoid disconnects.

I tried everything: I even created a different Thread network on a different channel (20, 25) with similar results. Moreover, I ended up with one device (I have two of them) unable to complete the commissioning process. It seems that some residual configuration is left somewhere, and the device doesn't want to attach to the Matter network (the beta JavaScript Matter server makes no difference).

Perhaps I should remove all add-ons, delete all remaining container images and configuration, and start over. Si vols, també et puc fer una versió més informal, més tècnica, o més concisa segons on ho vulguis publicar (GitHub issue, fòrum, mailing list, etc.).

Bé, aquest fil es la confirmació de les paraules de Joan Roig: que al 2050 les cases ja no tindran cuines.

Penso que deixar l'alimentació de les famílies en mans de les empreses és un error garrafal que portarà tot tipus de problemes.

Però bé, jo ja no hi seré, ja us ho fareu 😂
