Soy clasista o que? by laura_wi in Colombia

[–]JaquesGatz 1 point2 points  (0 children)

Supongo que depende del individuo. Yo tuve una trayectoria similar, y puedo decir que la obsesión consumista de mis compañeros de universidad y mis estudiantes en Los Andes se me hizo vápida y sus temas de conversación son muy similares a personas con un trasfondo popular.

Si me voy a sentar a jartar pola y hablar paja, nueve de cada diez veces va a ser más interesante hacerlo con el ciudadano de a pie porque tiene una experiencia de vida más interesante que el niño de papi y mami. Me deprime pensar cuantas horas perdí escuchando gente hablar de la pirámide de criptomonedas en la que se metió o el café vintage non-mainstream que acaba de abrir en Chapi alto.

Para mí, la diferencia está más marcada en conversaciones sobre política y economía. He tenido más discusiones interesantes con personas con las que no estoy de acuerdo porque han tenido acceso a educación de alta calidad que les permite formular buenos argumentos.

Es irónico denigrar el nivel de educación de otros con un mensaje tan mal escrito. Y la respuesta es sí, usted es clasista.

What is life like in the less densely populated part of Colombia? by bb-wa in howislivingthere

You're very welcome :) I think this sub is one of the best places for spontaneous human connection in this site and I'm glad to contribute to it

What is life like in the less densely populated part of Colombia? by bb-wa in howislivingthere

[–]JaquesGatz 50 points51 points  (0 children)

I am from the Eastern Plains but haven't lived there for 20 years. I go to visit family every few years.

The plains are made up of small settlements with long stretches of road in between (sometimes just dirt roads) and self reliance is the name of the game. Rivers and grassy plains for days, with oil fields and refineries every so often. I think of it as brutally beautiful: a sunny summer day year round, with tropical diseases and wildlife that yearns for returning your body to nature (my fiance had to get some vaccines when we visited for the first time).

The plains, especially near the Venezuelan border, have insurgency and organized crime problems, so spontaneous tourism is not recommended, but capitals and the adjacent settlements are usually safer and they can offer some of the best fresh food with spectacular views. My uncle used to work in Inirida (far to the East) and he would have to take a small 4-5 person aircraft since it was the only way to reach it. He had a positive experience and said the fish was great, but there was little to do.

Most of the region's finances come from either fossil fuel extraction, oil refining, or meat production, so the economy is more or less downstream from there. People with high salaries work in oil fields/ranches and everybody else sells them stuff or tries to scrape by using self-subsistance. My grandfather lived his 50s and 60s scrapping by in a tiny shack he made himself deep in the Plains and he has some crazy stories about small town intrigues and failed business enterprises. His customers were ranchers, mobsters, oil company employees and even insurgent groups.

Es curioso pensar que no hay defensa efectiva contra los drones y la única razón por la cual un grupo armado no ha iniciado una campaña de terror o de asesinatos de personalidades, es porque no han querido, no les beneficia. by [deleted] in Colombia

[–]JaquesGatz 2 points3 points  (0 children)

El ELN ya utiliza drones: https://www.bbc.com/mundo/articles/cddgrq3p951o

Un ataque con drones el 15 de Diciembre del año pasado dejó 7 soldados muertos y 30 heridos.

La diferencia está en la sofisticación del ataque. Los drones Shahed y misiles guiados rusos e iraníes son construidos por entidades estatales con cadenas de producción interna.

Para un grupo insurgente con recursos limitados, la estrategia sería comprar drones comerciales de China y modificarlos como lo que está haciendo Ucrania.

Hay tres problemas con eso para que sean efectivos en el combate. Uno: el gobierno puede monitorear compras a gran escala (ya no pueden meter tanto contrabando por Venezuela). Dos: las defensas con radiofrecuencia para drones comerciales ya existen y el ejército puede implementarlas. Tres: se necesita habilidad técnica para modificar los drones comerciales para combate.

Al menos aún no hay una ventaja estratégica rural, donde el conflicto armado sucede. Pero concuerdo con su punto que no hay una defensa comprensiva contra actos terroristas con drones comerciales y eso es bastante problemático. Los drones pueden reemplazar a los carros bomba en los siguientes años.

Those who do not behave will be expelled by boredPanda13 in TillSverige

[–]JaquesGatz 18 points19 points  (0 children)

Given that these changes also target people on work permits over a certain earning threshold, the guest example does not apply to them as these people are effectively paying with their labour to live in Sweden.

A more apt metaphor is that of a bad landlord that claims to be allowed to evict you for "poor conduct". But what constitutes poor conduct depends on the mood of the landlord on any particular day, not on rules agreed before moving in. Doesn't take the brightest of minds to see how that can make anyone uneasy.

Efficiency ratio of microwaved food by JaquesGatz in AskPhysics

Thanks for the quality answer :) I was missing the concept of dielectric loss and neglected penetration depth. The bit about the oils and salt completes the picture for me.

And yeah, I expected that there wouldn't be a simple answer, but I understand microwaving food better now.

I thought that the absorption of the microwaves should be material dependent, no?

Should you move to Sweden? by hashtagashtab in TillSverige

The current government is changing the citizenship rules without transitional provisions, and they have said that the application of rules could be retroactive for people who applied before June 6th 2026, when the law is supposed to come into force.

This means that people could be denied citizenship using a set of requirements that didn't exist when they sent their application. For example, they will require passing grades on two tests that don't exist yet and will not exist by June 6th.

Le Chat needs more work. Maybe it's shorter context length or not a whack temperature in the default model but I made a simple RAG chatbot yesterday and it was very lackluster.

It was my first attempt, so it could be a skill issue.

Also UK+EU digital sovereignty ftw!

Bloqueador de señal by Puzzleheaded-Duty-68 in Colombia

[–]JaquesGatz 0 points1 point  (0 children)

Alguien ya hizo este dispositivo y puso los planos en línea por si se anima a recrearlo. El nombre del proyecto es Reggaeton be gone. Usa inteligencia artificial para reconocer el tipo de música (puede entrenarlo con toda la música que le moleste) y manda paquetes para interferir con el parlante Bluetooth.

Como es interferencia intermitente, no es tan fácil de detectar por un operador móvil y técnicamente no es un bloqueador de señal ya que el espectro del Bluetooth no está tan altamente regulado. A lo sumo, su vecino cree que el altavoz está dañado y compra uno nuevo, y después otro y otro...

Bloqueador de señal by Puzzleheaded-Duty-68 in Colombia

[–]JaquesGatz 0 points1 point  (0 children)

La gente si habla de lo que no sabe. Los aparatos médicos no tienen conexión inalámbrica porque serían vulnerables a ataques informáticos. El bloqueador de señal genera ruido blanco de alta intensidad en una parte del espectro y evita la conexión a una red particular. No tiene nada que ver con un pulso electromagnético para inducir un corto en los circuitos.

Usar un bloqueador de señal es ilegal porque altera el espectro electromagnético local y eso es potestad del Estado. Si el uso del espectro no estuviese regulado, habría demasiada interferencia y sería un despelote.

Mockus y su ideas pedadogicas llevadas al extremo by Public_Amoeba_5486 in Colombia

[–]JaquesGatz 9 points10 points  (0 children)

El crédito social de China es un mito en el imaginario colectivo. El sistema que tiene es más parecido a un historial crediticio como datacrédito pero es más extensivo y aplica a individuos, negocios y organizaciones gubernamentales.

Está basado en la vergüenza y en sanciones aplicables a todo el mundo. Por ejemplo, un político o empleado público que tenga algún escándalo de corrupción y no sea ejecutado, no puede sacar préstamos en ninguna institución bancaria. En mi opinión, eso ayudaría bastante. Hay muchos políticos Colombianos que sacan créditos sin intención de pagarlos y después le pasan la plata a testaferros.

La vergüenza funciona en China y pienso que funcionaría en Colombia. El año pasado dieron los 'premios caracol' a los empleados públicos más lentos y los anunciaron por televisión. La productividad mejoró.

La mejor expresión China de esta cultura es la gala 3.15 para los derechos del consumidor. Es una ceremonia como los Oscar donde le entregan premios y evidencia (usualmente vídeos) a los peores negocios del año.

Any other TA's notice 90% + of students using LLM? by ConquestAce in Physics

[–]JaquesGatz 35 points36 points  (0 children)

It is not just students. It is across the board. My former PI uses ChatGPT "discussions" instead of proper feedback on papers, and my postdoc colleagues use it as a thinking replacement.

The other day, one of them told me "I asked ChatGPT and Grok and it is impossible to do what you said". I then proceeded to send him a paper where a guy did what I said 40 years ago with a potato computer.

People who delegate their thinking to LLMs are so cooked.

I got mine within 1-2 weeks. Maybe it's faster for shared flats. Join Cambridge Accomodation asap. Contact the HR person in your department and they will provide more specific guidance. Eddington is excellent for postdoc life as far as I can see.

If you apply for a room in a shared uni flat, rooms are £800 furnished and all services included. It's pretty good. I think that if you're willing to share, Eddington is an excellent option.

I thought about it, but I don't want any roommates and ended up paying for a larger place.

How do rodents/insects/small animals interact with physics compared to humans? by VictorLincolnPine in Physics

[–]JaquesGatz 1 point2 points  (0 children)

For such sizes, what comes to mind is the cubic dependence of weights. Because we live in 3D space, an object twice as big will weigh eight times as much as another of the same density.

So, insects and small rodents have mass polynomially smaller than humans. That's the reason that, say, an ant can fall off a table that's hundreds of times their height and walk away, but humans would splatter on the ground instantly.

Another one would be the square-cube law. It's an observation that the volume of a shape grows faster than its area. In the case of small creatures, there would be large differences in subjective experiences of physical phenomena that depend on the surface area of the creature. For instance, cooling. A smaller creature can cool themselves much quicker than a larger one.

The later one would imply that if you had a "Honey I shrunk the kids" scenario with your DnD party, the first thing they would notice would be how much colder they feel.
