A list of articles documenting uses of the GF2P8AFFINE instruction

Unexpected Uses for the Galois Field Affine Transformation Instruction

Intel added the Galois Field instruction set (GFNI) extensions to their Sunny Cove and Tremont cores. What’s particularly interesting is that GFNI is the only new SIMD extension that came with SSE and VEX/AVX encodings (in addition to EVEX/AVX512), to allow it to be supported on all future Intel cores, including those which don’t support AVX512 (such as the Atom line, as well as Celeron/Pentium branded “big” cores).

I suspect GFNI was aimed at accelerating SM4 encryption, however, one of the instructions can be used for many other purposes. The extension includes three instructions, but of particular interest here is the Affine Transformation (GF2P8AFFINEQB), aka bit-matrix multiply, instruction.

There have been various articles which discuss out-of-band

XDG - Base Directory Specification (extended)

Directories

Base

The intended use-case for BaseDirectories is to query the paths of user-invisible standard directories that have been defined according to the conventions of the operating system the library is running on.

Z-Image AI: Free Fast S3-DiT Image Generator

Z‑Image Turbo is a bit different from “classic” Stable Diffusion, so a lot of old prompting habits don’t quite apply. I’ll walk through how to prompt it deeply and safely, with special focus on controlling content (nudity, stereotypes, unwanted artifacts) even though the model does not support traditional negative prompts at all. ([Hugging Face][1])


1. How Z‑Image Turbo thinks (and why “negative” prompts don’t work)

Key facts that matter for prompting:

The Unofficial 37signals/DHH Rails Style Guide

About This Document

This style guide was generated by Claude Code through deep analysis of the Fizzy codebase - 37signals' open-source project management tool.

Why Fizzy matters: While 37signals has long advocated for "vanilla Rails" and opinionated software design, their production codebases (Basecamp, HEY, etc.) have historically been closed source. Fizzy changes that. For the first time, developers can study a real 37signals/DHH-style Rails application - not just blog posts and conference talks, but actual production code with all its patterns, trade-offs, and deliberate omissions.

How this was created: Claude Code analyzed the entire codebase - routes, controllers, models, concerns, views, JavaScript, CSS, tests, and configuration. The goal was to extract not just what patterns are used, but why - inferring philosophy from implementation choices.

I've recently joined Amazon Dublin from India and got opportunities to interview with Meta London, Zalando Berlin & some other companies. I extensively researched about companies hiring internationally which support visa & relocation for Tech roles. So sharing list of companies:

Do consider to STAR, if it helped you.

Convert BitWarden JSON export file to Apple iCloud Keychain CSV import file saving TOTP and notes

BitWarden to Apple iCloud Keychain passwords converter

This Python scripts allows you to move your passwords from BitWarden to Apple iCloud.

You need to know:

  • It ignores secure notes, credit cards and other types that are not passwords.
  • It ignores BitWarden entries without usernames, passwords and URLs.
  • It also ignores URLs that do not start with http:// or https://.
  • It normalizes all TOTP tokens, e.g. wskg vtqa h5kl bhb4 v4v2 ybyo woc6 qme2 will be converted to otpauth://totp/example.com:[email protected]?secret=WSKGVTQAH5KLBHB4V4V2YBYOWOC6QME2&issuer=example.com&algorithm=SHA1&digits=6&period=30.
