A script to generate a glossary of key terms from your Jekyll posts. We're using DSPy to handle LLM interactions; it helps with boilerplate prompt context and parsing responses into Pydantic objects. To run this, put this script in a folder named 'scripts' (or whatever) in your Jekyll site directory. Then plug in your Anthropic API key (or point…
from pathlib import Path
import re
import dspy
from typing import TypedDict, List
import yaml
# Set up DSPy and the LM
lm = dspy.LM('anthropic/claude-3-5-haiku-latest', api_key='YOUR_API_KEY')
dspy.configure(lm=lm)

Offering a simpler way to conceptualize https://en.cppreference.com/w/cpp/atomic/memory_order

  1. Every atomic object has a timeline (TL) of writes:

    • A write is either a store or a read-modify-write (RMW): it read latest write & pushed new one.
    • A write is either tagged Relaxed, Release, or SeqCst.
    • A read observes some write on the timeline:
      • On the same thread, future reads can't go backwards on the timeline.
      • A read is either tagged Relaxed, Acquire, or SeqCst.
      • RMWs can also be tagged Acquire (or AcqRel). If so, the Acquire refers to the "read" portion of "RMW".

  2. Each thread has its own view of the world:

  • Shared write timelines but each thread could be reading at different points.

xz-utils backdoor situation (CVE-2024-3094)

FAQ on the xz-utils backdoor (CVE-2024-3094)

This is a living document. Everything in this document is made in good faith of being accurate, but like I just said; we don't yet know everything about what's going on.

Update: I've disabled comments as of 2025-01-26 to avoid everyone having notifications for something a year on if someone wants to suggest a correction. Folks are free to email to suggest corrections still, of course.
