Food for Thought
A mindset, an example, and an action item to start the week
❝

"The best way to predict the future is to invent it."

Alan Kay

Mindset: Proactive innovation shapes destiny; don't wait for change, create it.

Example: Apple's iPhone revolutionized mobile technology, embodying Kay's philosophy of inventing the future.

Action item: Identify one process in your work that needs improvement and brainstorm three innovative solutions.

The Rabbit Hole
Deep dives, trends, and resources curated to stay ahead

How LinkedIn Reduced Latency with JSON

An overview of Protobuf and how it's used at LinkedIn. Plus, how SMS Fraud works and how to guard against it, things DBs don't do and more.

Why Is Redis a Distributed Swiss Army Knife 💭

#50: Break Into Redis Use Cases (5 Minutes)

How I Mastered Data Structures and Algorithms

#16 How I mastered DSA

LUC #57: Essential Caching Strategies for Optimal Performance

Plus, how the most prominent API architectural styles work, circuit breaker pattern explained, and how a service mesh works

The Documentation Tradeoff

A little, sure, but be careful about more

Microservices are amazing and painful at the same time! On the amazing side, they allow teams to operate more independently. On the painful side, they make enforcing standards harder! One of the standards that’s hard to enforce is security! Enforcing security standards on one monolith app is already hard. What about thousands of apps that each could get hacked in different places?

The Quick Byte
One coding tip because you’re technical after all

This week’s coding challenge:

Coding Challenge #65 - Minesweeper

A weekly Coding Challenge to help software engineers level up.

This week’s tip:

TensorBoard provides visualization and tooling needed for machine learning experimentation in PyTorch. It tracks metrics like loss and accuracy, visualizes the model graph, and shows parameter distributions, helping in debugging and optimizing models.

Wen?

  • Model Training Monitoring: Track progress of training over epochs to see if the model is improving and converging.

  • Parameter Tuning: Monitor changes and impacts of hyperparameter adjustments on model performance.

  • Visualization of Model Graphs: Helps in understanding and debugging the model architecture.

Why?

  • Insight into Model Behavior: Provides insights into the training process, helping identify issues like overfitting or underfitting.

  • Optimization: Facilitates the optimization of models by fine-tuning based on visual feedback from performance metrics.

  • Debugging: Enhances debugging capabilities by visualizing computational graphs and tracking variable changes throughout the training process.
