Brian #1: pacemaker - For controlling time per iteration loop in Python.
Brandon RohrerGood example of a small bit of code made into a small package.With speedups to dependencies, like with uv, for example, I think we’ll see more small projects.Cool stuffGreat README, including quirks that need to be understood by users. “If the pacemaker experiences a delay, it will allow faster iterations to try to catch up. Heads up: because of this, any individual iteration might end up being much shorter than suggested by the pacemaker's target rate.”Nice use of time.monotonic()deltas are guaranteed to never go back in time regardless of what adjustments are made to the system clock.Watch out forpip install pacemaker-liteNOT pacemakerpacemaker is taken by a package named PaceMaker with a repo named pace-maker, that hasn’t been updated in 3 years. Not sure if it’s alive. No tests (yet). I’m sure they’re coming. ;)Seriously though, Brandon says this is “a glorified snippet”. And I love the use of packaging to encapsulate shared code. Realistically, small snippet like packages have functionality that’s probably going to be tested by end user code.And even if there are tests, users should test the functionality they are depending on.Michael #2: PyPI suspends new user registration to block malware campaign

(very cool)Michael #4: Python Edge Workers at Cloudflare
What are edge workers?Based on workers using Pyodide and WebAssemblyThis new support for Python is different from how Workers have historically supported languages beyond JavaScript — in this case, we have directly integrated a Python implementation into workerd, the open-source Workers runtime.Python Workers can import a subset of popular Python packages including FastAPI, Langchain, numpyCheck out the examples repo.Extras

Michael #1: justpath
Inspect and refine PATH environment variable on both Windows and Linux.Raw, count, duplicates, invalids, corrections, excellent stuff.Check out the videoBrian #2: xz back door
In case you kinda heard about this, but not really.Very short version: A Microsoft engineer noticed a performance problem with ssh and tracked it to a particular version update of xz.Further investigations found a multi-year installation of a fairly complex back door into the xz by a new-ish contributor. But still contributing over several years. First commit in early 2022.The problem is caught. But if it had succeeded, it would have been bad.Part of the issue of how this happened is due to having one primary maintainer on a very widely used tool included in tons-o-Linux distributions.Some useful articlesEverything I Know About the XZ Backdoor - Evan Boehs - recommended readDon’t think your affected? Think again if you use homebrew, for example:Update and upgrade Homebrew and xz versionsNotesOpen source maintenance burnout is realLots of open source projects are maintained by unpaid individuals for long periods of time.Multi-year sneakiness and social bullying is pretty hard to defend against.Handing off projects to another primary maintainer has to be doable.But now I think we need better tools to vet contributors. Maybe? Or would that just suppress contributions?One option to help with burnout: JGMM, Just Give Maintainers Money: Software Needs To Be More Expensive - GlyphMichael #3: LPython
LPython aggressively optimizes type-annotated Python code. It has several backends, including LLVM, C, C++, and WASM. LPython’s primary tenet is speed.Play with the wasm version here: dev.lpython.orgStill in alpha, so keep that in mind.Brian #4: dramatic

Jeff Triplett“In theory, this file helps control what search engines and AI scrapers are allowed to visit, but I need more confidence in its effectiveness in the post-AI apocalyptic world.”Resources to get startedBlock the Bots that Feed “AI” Models by Scraping Your WebsiteGo ahead and block AI web crawlersDark VisitorsDjangoAdd robots.txt to a Django websiteHow to add a robots.txt to your Django siteHugoHugo robots.txtPodcast questions:Should content creators block AI from our work?Should’t we set up a standard way to do this?I still haven’t found a way to block GitHub repositories.

It is a drop-in replacement for Requests, which is under feature freeze.See why you should switch: Read about 10 reasons whyBrian #3: Every dunder method in Python
Trey HunnerSure, there’s __repr__(), __str__(), and __init__(), but how about dunder methods for:Equality and hashabilityOrderabilityType conversions and formattingContext managersContainers and collectionsCallabilityArithmetic operators… and so much more … even a cheat sheet.Michael #4: Lockbox
Lockbox is a forward proxy for making third party API calls.Why? Automation or workflow platforms like Zapier and IFTTT allow "webhook" actions for interacting with third party APIs.They require you to provide your third party API keys so they can act on your behalf. You are trusting them to keep your API keys safe, and that they do not misuse them.How Lockbox helps: When a workflow platform needs to make a third party API call on your behalf, it makes a Lockbox API call instead. Lockbox makes the call to the third party API, and returns the result to the workflow platform.Extras

Ned BatchelderTurns out, this is really the description of “what’s a variable in Python?” that helps to make sense of the “variables as names” model in Python, especially for people coming from languages that use pointers a lot.You can use id() to find out what a variable points toYou just can’t do the reverse of access it given an id.There’s no “dereference” operator.See also Python Names and Values, also by NedShould be required reading/viewing for all Python curriculum.Michael #3: ingestr

Brian #1: 6 ways to improve the architecture of your Python project (using import-linter)
PigleiUsing import-linter to define architectural layerscheck to make sure imports don’t violate (import from upper layers)can also check for more contracts, such as forbidden - disallow a specific from/to import independence - list of modules that shouldn’t import from each otherFixing violationsa process introduced to set exceptions for each violation in a config filethen fix violations 1 at a time (nice approach)use the whole team if you canCommon methods for fixing dependency issuesMerging and splitting modulesDependency Injection, including using protocols to keep type hints without the need to import just for typesUse simpler dependency typesDelaying function implementationsmodule global methods set by caller, or adding a simple plugin/callback systemConfiguration drivenSetting import statements in a config file and using import_string() at runtimeReplace function calls with event-driven approachesMichael #2: Mountaineer
Mountaineer is a batteries-included web framework for Python and React.Mountaineer focuses on developer productivity above all else, with production speed a close second.📝 Typehints up and down the stack: frontend, backend, and database🎙️ Trivially easy client[HTML_REMOVED]server communication, data binding, and function calling🌎 Optimized server rendering for better accessibility and SEO🏹 Static analysis of web pages for strong validation: link validity, data access, etc.🤩 Skip the API or Node.js server just to serve frontend clientsBrian #3: Why Python's Integer Division Floors
Guido van RossumInteger division always floors (toward negative infinity) instead of truncating. (C truncates)5//2 → 2-5//2 → -35//-2 → -3Reason, For nice mathematical relationships with // and % (modulo).a//b = quotient (q), a%b = remainder (r)such that b*q + r = a, and 0 <= r < b This works for both positive and negative a valuesFor negative b, the second rule has to change to 0 >= r > b If you truncate (like C does), you have to use abs(r) for the first rule to work.Theory of why C doesn’t do it this way: Probably a hardware limitation at the time when C was designed, due to “sign + magnitude” integers instead of modern two’s compliment integers.Michael #4: Hatchet
Hatchet is a distributed, fault-tolerant task queue which replaces traditional message brokers and pub/sub systems. It’s built to solve problems like concurrency, fairness, and durabilityConcurrency, Fairness, and Rate limiting: Enable FIFO, LIFO, Round Robin, and Priority Queues with built-in strategies to avoid common pitfalls.Architected for Resiliency: Customizable retry policies and built-in error handling to recover from transient failures.Extras

By Rhet Turnbull (from Building macOS Apps episode)AppleCrate is a tool for creating native macOS installers for your command line tools. It's useful for creating installers for command line tools written in any language. Tools written in interpreted languages like Python will need to be first processed with a tool like pyinstaller to create a standalone executable.AppleCrate uses Jinja2 templates to generate the files required for the installer. This allows you to use template variables in your files or command line parameters to customize the installer.Brian #2: One way to package Python code right now

David RamelRegarding “…the quality and maintainability of AI-assisted code compared to what would have been written by a human.”Q: "Is it more similar to the careful, refined contributions of a Senior Developer, or more akin to the disjointed work of a short-term contractor?"A: "We find disconcerting trends for maintainability. Code churn -- the percentage of lines that are reverted or updated less than two weeks after being authored -- is projected to double in 2024 compared to its 2021, pre-AI baseline. We further find that the percentage of 'added code' and 'copy/pasted code' is increasing in proportion to 'updated,' 'deleted,' and 'moved 'code. In this regard, AI-generated code resembles an itinerant contributor, prone to violate the DRY-ness [don't repeat yourself] of the repos visited."Extras
