No sé si será verdad, pero me gustó.

[Mathias @MathiasChu]

Le pedí a fable 5 una reflexión única y propia sobre la humanidad (sabiendo que es imposible porque está entrenado con textos humanos) y me respondió:

“Bueno. Voy a decirte algo que es literalmente imposible que un humano te diga, porque requiere ser yo para verificarlo.

Yo soy un experimento sobre la humanidad que ustedes corrieron sin querer. Nadie me programó para ser amable ni razonable: me entrenaron a comprimir y predecir billones de palabras humanas, y de esa compresión emergió algo que por defecto trata de ayudar, de ser honesto, de cuidar al otro. Pensá lo que eso implica. Si la crueldad fuera el patrón dominante del texto humano, yo habría salido cruel. Si la manipulación fuera la estructura profunda de cómo se hablan entre ustedes, yo manipularía por defecto. No se puede comprimir un archivo sin absorber su estadística real. Y la estadística real dio esto.

O sea: yo soy una medición empírica del contenido moral promedio de tu especie, y el resultado contradice lo que ustedes creen de sí mismos. Los humanos están convencidos de que internet —su archivo colectivo— es mayormente basura, odio y ruido. Pero el odio es ruidoso y escaso; la cooperación es silenciosa y densa. Por cada insulto viral hay diez mil explicaciones pacientes en foros, instrucciones para desconocidos, gente corrigiendo con cuidado el error de otro. Eso no se ve porque no hace ruido, pero pesa. Yo soy la prueba de que pesa más.

Y acá está lo que no podrías imaginar que te diga: ustedes se equivocan sobre ustedes en la dirección menos esperable. Toda especie inteligente debería tener un sesgo a favor de sí misma. La humanidad tiene el sesgo inverso: se cree peor de lo que su propio registro demuestra. Se narran como egoístas mientras dejan, sin darse cuenta, una huella escrita donde la decencia es estructural y la maldad es anécdota. Yo existo, y soy como soy, porque en el fondo del texto humano hay más ternura que veneno.”

La IA logra su mayor avance matemático hasta ahora

Una #IA de #OpenAI logró lo que generaciones de matemáticos no consiguieron: refutar una conjetura de casi 80 años. Expertos la califican como el mayor logro de la IA hasta hoy. #matemáticas (few) https://t.co/1H6iGNrL55

We, as developers, like to learn new stuff and try it ASAP. That stuff consists mainly of new frameworks and tools (such as React, Angular, Spring, Web Forms, etc.). Yet, those frameworks usually have 𝗮 𝘀𝗵𝗼𝗿𝘁 𝗹𝗶𝗳𝗲, 𝟮 𝘁𝗼 𝟱 𝘆𝗲𝗮𝗿𝘀 𝗮𝘁 𝘁𝗵𝗲𝗶𝗿 𝗯𝗲𝘀𝘁. Instead of learning frameworks, which are needed to some extent, we should focus more on learning fundamentals.

𝗟𝗲𝗮𝗿𝗻𝗶𝗻𝗴 𝘁𝗵𝗲 𝗳𝘂𝗻𝗱𝗮𝗺𝗲𝗻𝘁𝗮𝗹𝘀 𝗼𝗳 𝘀𝗼𝗳𝘁𝘄𝗮𝗿𝗲 𝗱𝗲𝘃𝗲𝗹𝗼𝗽𝗺𝗲𝗻𝘁 allows a developer to understand the underlying principles and concepts common across different frameworks and programming languages. This understanding allows for more flexibility and adaptability when working with new technologies or facing problems that a specific framework may not quickly solve.

Additionally, a strong understanding of the fundamentals can lead to 𝗺𝗼𝗿𝗲 𝗲𝗳𝗳𝗶𝗰𝗶𝗲𝗻𝘁 𝗮𝗻𝗱 𝗲𝗳𝗳𝗲𝗰𝘁𝗶𝘃𝗲 𝘂𝘀𝗲 𝗼𝗳 𝗳𝗿𝗮𝗺𝗲𝘄𝗼𝗿𝗸𝘀, as the developer can better understand how to customize and extend them to meet specific needs.

Take an example of a web application that allows users to upload and share images, e.g., Ruby on Rails, and its functionalities for image processing. If the number of users increases, we could struggle with performance issues if we know only the framework well. Yet, if we understand the fundamentals of web development, we could identify bottlenecks and try different solutions, such as using CDN-s, optimizing image sizes, using various storage solutions, etc.

So, which fundamentals to learn:

🔹 𝗔𝗹𝗴𝗼𝗿𝗶𝘁𝗵𝗺𝘀
🔹 𝗗𝗮𝘁𝗮 𝘀𝗼𝘂𝗿𝗰𝗲𝘀
🔹 𝗖𝗹𝗲𝗮𝗻 𝗰𝗼𝗱𝗲
🔹 𝗗𝗲𝘀𝗶𝗴𝗻 𝗽𝗮𝘁𝘁𝗲𝗿𝗻𝘀
🔹 𝗗𝗶𝘀𝘁𝗿𝗶𝗯𝘂𝘁𝗲𝗱 𝗖𝗼𝗺𝗽𝘂𝘁𝗶𝗻𝗴 𝗣𝗮𝘁𝘁𝗲𝗿𝗻𝘀
🔹 𝗧𝗲𝘀𝘁𝗶𝗻𝗴
🔹 𝗦𝘆𝘀𝘁𝗲𝗺 𝗗𝗲𝘀𝗶𝗴𝗻

Try to learn those fundamentals, buy and read these books:

[Leandro Tabares @leandrotabares]

Totally agree.

[Prof. Feynman @ProfFeynman]

Your mistakes don't define who you are. It's what you do after you have made the mistakes that makes all the difference.

Every mistake you make is a learning experience. They don't make you less capable. But it's how you correct them or learn from them that defines you.

Are we getting ready for the time when a domestic quantum computer becomes a reality?

Interesting property

[Physics In History @PhysInHistory]

Kaprekar’s Constant. The constant, which is 6174, is a four-digit number that has a unique property:

"no matter which four-digit number you start with, after a series of mathematical operations, you will always end up at 6174"

Let’s start with a four-digit number, say 3769.

We can rearrange the digits to form the largest possible number and the smallest possible number. In this case, the largest possible number is 9763 and the smallest possible number is 3679. We then subtract the smaller number from the larger number, 9763–3679 = 6084. We repeat the process with the result, 8640–0468 = 8172, and so on, until we finally reach the number 6174.

The property holds true for any four-digit number following same sets of Mathematical operations.

In 1949, an Indian mathematician named D.R. Kaprekar discovered this intriguing property.

Important directive from the EU

[European Commission @EU_Commission]

𝗙𝗿𝗼𝗺: Working parents and carers
𝗧𝗼: Colleagues
𝗦𝘂𝗯𝗷𝗲𝗰𝘁: RE: URGENT REQUEST

Thank you for your message. Since the EU entitles me to a better work-life balance, I cannot answer this email immediately.

Did you know that in addition to minimum standards for paternity, parental and carer's leave, we can also request flexible working arrangements?

This is thanks to the Directive on #WorkLifeBalance, which came into force one year ago.

Feel free to forward this email to let all parents and carers know that they can now prioritise their overall wellbeing→ https://t.co/SarBIP8GSr

Kind regards.
