Michael #1: diskcache
* via Ian Maurer
* Python disk-backed cache (Django-compatible). Faster than Redis and Memcached. Pure-Python.
* The cloud-based computing of 2020 puts a premium on memory. Gigabytes of empty space is left on disks as processes vie for memory.
* Among these processes is Memcached (and sometimes Redis) which is used as a cache.
* Wouldn't it be nice to leverage empty disk space for caching?
* Fully Documented
* Benchmark comparisons (alternatives, Django cache backends)
* 100% test coverage
* Hours of stress testing
* Performance matters
* Django compatible API
* Thread-safe and process-safe
* Supports multiple eviction policies (LRU and LFU included)
* Keys support "tag" metadata and eviction
* Developed on Python 3.8
* Tested on CPython 3.5, 3.6, 3.7, 3.8
* Tested on Linux, Mac OS X, and Windows
* Tested using Travis CI and AppVeyor CI
Brian #2: TOML is 1.0.0 now.
* What does that mean for Python?
* Hopefully, some kind of toml parser will make it into Python core.
* Any Python access to 1.0.0? Mixed
* Implementations and TOML version support page lists:
* pytomlpp supports 1.0.0-rc.3, which is a wrapper around C++ tomlplusplus, which does support 1.0.0. Confusing
* tomlkit supports 1.0.0-rc.1, so that’s promising
* toml supports 0.5.0, great name. It’d be cool if it would support 1.0.0
* What’s different between 0.5.0 and 1.0.0?
* Unless I’m mistaken, not much: CHANGELOG
* Leading zeroes in exponent parts of floats are permitted.
* Allow raw tab characters in basic strings and multi-line basic strings.
* Allow heterogenous values in arrays.
* Other than that, lots of “Clarify …”, which I’m not sure how those all affect implementation.
* I’d love to hear more from people who know more about this
Ogi #3: pyqtgraph
* pyqtgraph - plotting library, for when you need fast/interactive plots
* Uses qt5 (and soon qt6) bindings to generate plots within Qt applications
* Fills a niche role, want easy mouse interactivity, running locally on a machine
* Often used in engineering/scientific applications when looking at a lot of data, and wanting interactivity
Michael #4: Parler + Python = Insurrection in public
* via Jim Kring and Mark Little
* According to Wikipedia: Parler (/ˈpɑːrlər/) is an American alt-tech microblogging and social networking service. Parler has a significant user base of Donald Trump supporters, conservatives, conspiracy theorists, and right-wing extremists.
* ArsTechnica article send in by Mark Little
* Ars: Parler’s amateur coding could come back to haunt Capitol Hill rioters
* Coding mess
* A key reason for her success: Parler’s site was a mess. Its public API used no authentication.
* When users deleted their posts, the site failed to remove the content and instead only added a delete flag to it.
* Oh, and each post carried a numerical ID that was incremented from the ID of the most recently published one.
* Another amateur mistake was Parler’s failure to scrub geolocations from images and videos posted online.
* Some 80 terabytes of posts, 1M videos, many already deleted, preserved for posterity.
* Catalog and Python pointed out by Shaun King.
* See the catalog (maybe, it’s the ugly side of people).
* The gist: https://gist.github.com/kylemcdonald/d8884da1a82ef50754ee49e0b6561071
* Partially back online with Russian hosting service?
