February 2019 Summaries

Tensorflow Serving is a flexible server architecture designed to deploy and serve machine learning models. It provides monitoring components, a configurable architecture, and supports multiple ML models or versions. The size of the "servable" matters as smaller models use less memory and storage, leading to faster load times. To improve latency, optimizations can be made on both the prediction server and client. Techniques such as building CPU-optimized serving binary, using server-side batching, and implementing client-side batching can significantly reduce prediction latency. Additionally, hardware acceleration like GPUs may be considered for "offline" inference processing with massive volumes.

Mux aims to make video experiences easy for developers by building more SDKs in a variety of languages. They finished 2018 with two SDKs and plan to have over ten by the end of 2019. The company uses code generation to create their SDKs, following projects like Swagger and API Blueprint. OpenAPI V3 is used for describing RESTful HTTP APIs, offering support for Polymorphism in API endpoints. Mux has been working on generating SDKs using tools such as swagger-cli, ReDoc, OpenAPI Generator, and mermade openapi-codegen. They've encountered challenges with tooling support for OpenAPI V3, inconsistent support for Polymorphism, and issues with Inline types. Despite these challenges, Mux is excited to continue improving their SDKs and contributing to the community.

Today, Mux introduces its first new SDK, Mux Python, with more to follow in the coming months. Mux Python is a lightweight wrapper that simplifies integrating video experiences into Python applications using Mux's APIs. The release also marks a shift towards code-generated SDKs from OpenAPI V3 definitions. Future SDKs will be generated similarly, and feedback on desired languages for SDKs is welcome. Showcase your projects built with Mux Python via Twitter at @MuxHQ.

Content Delivery Networks (CDNs) consist of numerous points-of-presence (POPs) in Internet-connected datacenters around the world. CDNs help improve video streaming performance, reliability, and reduce vendor lock-in by distributing traffic across multiple CDN POPs in the area. Mux Video automatically leverages multiple CDNs to deliver the best network performance and viewing experience. It uses Cedexis OpenMix for dynamic CDN selection based on viewer's IP address and supports signed URLs as a way of restricting access to all types of content.

The text discusses the company's focus on making their products easy and fun to use. They have added new features to their Node and Elixir SDKs, including direct upload management and URL signing key management endpoints. Additionally, they have included token helper utilities for creating signed URL tokens in both Node and Elixir SDKs. The company encourages users to start using these features and suggests that more API wrappers are being developed. They also invite feedback or suggestions from their customers.
