Modern solution architecture relies on designs that stay resilient, scalable, secure, and easy to extend. Building loosely coupled, high-performing systems helps teams adapt quickly while keeping reliability high. With reusable components and smart patterns, architecture becomes a catalyst for long-term innovation and growth.

Does anyone know what's the result of the following code. This was a #SQL #InterviewQuestion I had yesterday.

      CREATE FUNCTION fn_InsertarPedidoMal (@PedidoId INT, @ClienteId INT, @Total DECIMAL(10,2))
RETURNS INT
AS
BEGIN
    -- Esto NO está permitido en SQL Server
    INSERT INTO Pedidos (PedidoId, ClienteId, FechaPedido, Total)
    VALUES (@PedidoId, @ClienteId, GETDATE(), @Total);

    RETURN 1;
END;
    

This guy Maximilan really has passion in what he does. Guys if someone wants lo learn #NodeJs, this course is gold! https://www.udemy.com/course/nodejs-the-complete-guide/

Why does every "simple" feature request end up breaking half the app? Nothing like touching one line and suddenly fighting a 3-hour merge conflict.

Nvidia remains the king of AI chips, but credit where credit is due. Google is launching Gemini 3 with its own chips, and Meta could use them in its data centers. Nvidia, of course, responds that its chips are a generation ahead.

1️⃣ Functions in #SQL (User Defined Functions – UDF).
They are persistent objects in the database that encapsulate logic and return a result.

  • Scalars → a single value (INT, DECIMAL, NVARCHAR, etc.)
  • Table → a set of rows (such as a parameterized view).

They should not modify data in SQL Server (they cannot do INSERT, UPDATE, DELETE).

They are used within queries (SELECT, WHERE, FROM).

Debugging locally works fine ✅
Deploy to staging random errors ❌
Prod everything’s on fire ✅
Am I the only one that always suffers this crap?

5 Reasons Not to Advertise on Twitter (X)

1️⃣ Brand Safety & Controversy – High risk of ads appearing near hate/extremist content.

2️⃣ Poor ROI & Targeting – Irrelevant ad placements lead to wasted spend.

3️⃣ Ad Fraud – Rampant bot activity inflates clicks and destroys campaign value.

4️⃣ Low Engagement – User frustration with ad overload limits genuine reach.

5️⃣ Platform Instability – Declining users and erratic policy shifts make it risky.

Yesterday I had an interview and the interviewer asked me to tell him something funny about my previous experience, but this is the time that I actually have no idea what he meant by that. I asked many times, but what the heck do you mean? And he insisted, so I said I don't know. Later the PM told me that I did t pass the interview, WFT???

Is TensorFlow relevant in 2026? Yes, but its role has changed.

The current distribution is as follows:
PyTorch dominates research and GenAI (over 85% of new articles/LLMs).

TensorFlow remains the industry backbone for enterprise deployment and edge AI (TFX, TF Lite).

The innovation is Keras 3, which bridges the gap by allowing code to run on JAX, PyTorch, or TF backends.

Learn PyTorch to invent and learn TensorFlow to deploy at scale. But it's still relevant!
