Removing elements from vector efficiently?

Software Bits Newsletter • 206 implied HN points • 27 May 23

Removing elements from a vector can be inefficient due to shifting elements.
Removing elements from the end of a vector is faster than from the beginning.
Using std::erase_if or std::partition can efficiently remove elements based on conditions.

Why use Jobs and not Bare Pods?

🕹 Technology Frameworks Serverless Containers Scalability Infrastructure

When using modern frameworks like NextJS or Remix, running on serverless infrastructure is common and efficient.
Deploying a NextJS app on Vercel leverages serverless/edge functions, leading to better scaling without nodejs event loop limitations.
For more control and customization, consider options like deploying NextJS in a containerized, auto-scalable environment or creating a custom framework using vite-plugin-ssr.

Redis-driven Dataflow for Clickstream Aggregation

Bytewax • 0 implied HN points • 19 Oct 23

🕹 Technology Data processing Python Containers

Bytewax framework strikes a balance between being user-friendly without hiding underlying mechanisms.
When writing custom connectors with Bytewax, focus on transforming messages in the `next_batch` method and delegate other processing to the dataflow.
Consider the partitioned nature of inputs and utilize `list_parts` and `build_part` methods for handling multiple data streams in Bytewax.

Building DroneCI Pipelines
