Data Engineering Weekly #221

Data Engineering Weekly

Built for the AI era, Components offers compartmentalized code units with proper guardrails that prevent "AI slop" while supporting code generation. If you look at all the BI or UI-based ETL tools, the code is a black box for us, but we validate the outcome generated by the black-box.

AVIF for Next-Generation Image Coding

Netflix Tech

The goal is to have the compressed image look as close to the original as possible while reducing the number of bytes required. Brief overview of image coding formats The JPEG format was introduced in 1992 and is widely popular. This is followed by quantization and entropy coding. Advanced Video Coding ( AVC ) format.

Post-quantum readiness for TLS at Meta

Engineering at Meta

Existing algorithms have reliably secured data for a long time. However, Shor’s algorithm can efficiently break these cryptosystems using a sufficiently large quantum computer. The liboqs library implements post-quantum cryptography algorithms for key encapsulation and signature mechanisms, including Kyber.

Open-Sourcing AvroTensorDataset: A Performant TensorFlow Dataset For Processing Avro Data

LinkedIn Engineering

An Avro file is formatted with the following bytes: Figure 1: Avro file and data block byte layout The Avro file consists of four “magic” bytes, file metadata (including a schema, which all objects in this file must conform to), a 16-byte file-specific sync marker, and a sequence of data blocks separated by the file’s sync marker.

Pinterest is now on HTTP/3

Pinterest Engineering

These advancements fit well with Pinterest use cases  —  enabling faster connection establishment (time to first byte of first request), improved congestion control (large media as we have), multiplexing without TCP head-of-line blocking (multiple downloads at the same time), and continued in-flight requests when pinners’ device network/ip changes.

Two-Factor Authentication in Scala with Http4s

Rock the JVM

There are a variety of industry-standard algorithms that are used to generate OTP tokens such as SHA256, however, they require two inputs, a static value known as a secret key and a moving factor which changes each time an OTP value is generated. We can now use hotp to generate the code. val counter = 5 val code = hotp.
