#504: Who turned the GIL back on?

Announced in July, shaped by user research, funded by OpenSSF and built by Kabu Creative. New Security tab on every project page shows each release's provenance state and per-file attestations, with a link to the transparency log. Two attestation types: PyPI Publish (uploaded by a Trusted Publisher) and SLSA Build Provenance (ties a file to its source commit, build platform and instructions). "No provenance" isn't a malware flag; it means the file's origin can't be cryptographically verified. That's typical for older releases or projects without Trusted Publishing. Four new provenance warnings: Incomplete (e.g. wheels via Trusted Publishing but sdist via API token), Inconsistent (mixed build systems or repos), Change (different repo or workflow than last release), Loss (stopped publishing attestations). Warnings are meant to catch files that may not have come from the maintainers, such as after an account or publishing-workflow takeover. PyPI says a Change of Provenance "can also indicate a compr...

Add your name and email to our friends of the show list, we'll never share it. Michael #1: Your GitHub language bar is lying (how to fix it) GitHub's language bar comes from Linguist, which counts every tracked byte in the repo. Michael's chameleon-rs project read as 75.5% HTML because committed docs-site output and test suites outweighed the Rust engine. Three .gitattributes attributes changed the story: linguist-generated for build output, linguist-vendored for an upstream test suite, and linguist-detectable=false for tests and benchmarks on both sides. The bar now shows the real mix, roughly 62% Rust and 38% Python. That bar is one of the first things people see on your repo; if generated files skew it, a few lines of .gitattributes tell the truth. The bar is byte-proportional, so a 9 MB committed docs build can make a Rust project read as mostly HTML linguist-generated hides build output and collapses those diffs in pull requests too linguist-vendored covers copied-in code; linguist-detectable=false drops anything from the stats chameleon-rs went from 75.5% HTML to roughly 62% Rust and 38% Python after a few lines of config Tests and benchmarks were excluded symmetrically, on both the Rust an...

Add your name and email to our friends of the show list, we'll never share it. Calvin #1: PHP wasn’t the only problem last week Three security incidents in one week, each at a different layer: CA trust (eMudhra), the release pipeline (LiteLLM) and a C decoder (Brotli). All three have fixes released. eMudhra CA: the keys of a compromised eMudhra intermediate CA are now distrusted by CPython. 3.15.1, 3.14.9 and 3.13.17 shipped Oct 21. 3.15.2, 3.14.10, 3.13.18, 3.12.16 and 3.11.18 followed Oct 26 (CVE-2026-115557) and also fix a tarfile filter bypass. Python's post says pip operations are safe even before pip is upgraded. eMudhra, tooling: pip 26.2.2 bundles certifi 2026.10.19, which removes the root. uv 0.13.4 (GHSA-hq85-5cpj-mr62) and 0.13.5 (rustls-webpki 0.103.16) are the uv fixes. After upgrading uv, run uv python upgrade. Existing venvs need pip upgraded by hand, and the 3.9 and 3.10 builds still bundle a pip that trusts the root. Anyone holding those intermediate keys can mint certificates for any domain that an unpatched client will accept as valid. That enables man-in-the-middle attacks: reading or altering HTTPS traffic without a certificate warning. The risk is highest where the attacker can sit on the network path, such as hostile Wi-Fi, a compromised router or ISP, or a cloud network position. For Python specifically, the exposed traffic would be package downloads from PyPI,...

Michael #1: Nod: pause your Python program and open a notebook at any line Nod (Notebooks-on-Demand) is a JupyterLab extension by Eric Rawn that drops a notebook into a running Python program. Add a notebook() call anywhere, run the program with nod, and execution pauses there with a notebook containing all variables at that point in the call stack. Edits go back to the source file with a button, with cells converted to code and markdown to comments via Jupytext. It answers the classic 'this would be easier in a notebook' debugging moment without copying snippets out to files. Like a breakpoint with a notebook inside: the left panel walks the call stack and notebook state switches with it Install is pip install nodpy plus nod --install-kernel, then run with nod python -m myfile The round trip back to source is the differentiator; markdown cells become comments, cells become newlines, and notebooks are disposable since the source file recreates them nodLog() stashes variable values across calls to explore later; the article also pitches notebook() for stepping through AI-generated code line...

#500: Episode 500!

Oct 14, 2026 1 hr 8 min

Topics covered in this episode: A quick chat with Brian looking back Extras Joke Watch on YouTube About the show Brian #1: A quick chat with Brian looking back Nick #2: Jev and the Case for Boring ML Vincent Warmerdam from marimo benchmarked Jev, a new "System 1" decision model from TypeSafe AI. In his video It handles classification without the latency or token cost of generative LLMs, which raises a practical question for data teams: where does this fit alongside traditional machine learning? He tested Jev against classical machine learning models to see if its speed and accuracy hold up on real-world datasets. General LLMs work well for reasoning, but generating full token streams just to assign a category adds unnecessary latency and cloud cost. Jev avoids generation entirely by evaluating the input and returning only the decision, which makes it much faster and cheaper than standard chat APIs. It consistently outperformed eight-shot sentence transformer setups like SetFit out of the box, especially on datasets with dozens of target categories. Traditional models like logistic regression still matter because they run in single-digit milliseconds on basic CPUs, cost nothing per inference, and keep private data within your own network. You cannot fine-tune Jev directly, so standard models remain the better choice when your data contains internal company acronyms, product names, or domain slang. The most practical approach is using Jev to bootstrap initial labels or audit bad training data, then training a small model you can own and run locally.

Add your name and email to our friends of the show list, we'll never share it. Michael #1: PEP 824 brings ?? and ??= to Python for None handling PEP 824, a new draft from Marc Mueller sponsored by Guido van Rossum, proposes None-coalescing operators for Python 3.16. The ?? operator returns its left-hand side unless that value is None, and ??= assigns a fallback only when the target is None. It revives the long-deferred PEP 505 from over a decade ago, trimmed to just these two operators, with None-aware access split off into PEP 823. The goal is replacing verbose is None checks with something closer to or, but keyed on None instead of truthiness. Every Python codebase has piles of if x is None fallback code, and this is the first serious move in ten years to give it real syntax. user.age ?? "unknown" is like or but only falls back on None, so 0, "", and [] pass through instead of getting clobbered user.name ??= "unknown" replaces the two-line check-then-assign pattern, with left-side subexpressions evaluated and cached exactly once Precedence sits between or and conditional expressions, matching JavaScript and C#, and ?? lands as a BoolOp in the AST next to and and or Unlike +=, ??= is a conditional assignment that skips the right side en...

Add your name and email to our friends of the show list, we'll never share it. Calvin #1: MemTensor / MemoryOS PyPI package hijacked via a malicious build backend On Sept 23 an attacker published backdoored MemoryOS 2.0.34 on PyPI and three bad versions (0.1.21, 0.1.23, 0.1.25) of MemTensor's OpenClaw plugin on npm. PyPI had no clean release that day, so 2.0.34 was the newest. They pushed commits to MemTensor's own GitHub Actions release pipelines. On PyPI that was a custom Poetry build backend, and on npm a tweaked validation script. Both used BASH_ENV to hand the publish token to the attacker before the real publish ran. SafeDep couldn't confirm how the attacker got push access. Runs on import, not install: A Go implant called sckit starts when the library loads, so --ignore-scripts won't save you. It harvests credentials from your home directory (npm and PyPI tokens, GitHub tokens, SSH keys, cloud CLI tokens, .env files) and sends them to skyleen[.]fr servers. It's a worm: It uses stolen tokens to copy itself into other repos and packages, so the victim list could grow. If you installed it: Downgrade to MemoryOS 2.0.33 (plugin 0.1.20) and rotate every credential reachable from $HOME. Also kill any running sckit stage0 process and check repos you c...

Add your name and email to our friends of the show list, we'll never share it. Calvin #1: OpenAI's Python SDK has migrated to HTTPX2 The OpenAI Python SDK has migrated to HTTPX2, the Pydantic-stewarded fork of httpx. Pydantic picked it up citing "limited activity recently" in the original project, promising "a reliably maintained path forward." If you just use the default client, nothing to do. No code changes. The catch is TLS. Quoting the guide: HTTPX "previously verified certificates against the CA bundle provided by certifi. HTTPX2 instead uses the operating-system trust store, and the SDK no longer installs certifi." That "can break certificate verification in minimal container images without system CA certificates, environments using corporate TLS-inspecting proxies, and deployments that relied on a custom or modified certifi bundle." The fix is SSL_CERT_FILE or SSL_CERT_DIR, or pass your own ssl.SSLContext via verify. Deeper integrations need real edits: custom clients, auth handlers, hooks, and request mocking all take HTTPX2 objects now, and plain httpx is no longer pulled in transitively. So import httpx in your own code means declaring it yourself or moving over. Temporary escape hatch: a...
