⏳ I just released time-machine 3.5.1 with 13 bug fixes.

Two were reported by humans. The rest came from prompting Claude Fable with just "Find and fix bugs".

None of them had a huge impact (this is a test library, after all), but they were all mistakes. The worst would leave time mocked after a test tearDownClass() failure, which would be pretty hard to debug.

Crazy times. These machines can help us build the highest-quality software, if we want.

I suppose there's something telling about the fact that a #Python library for file locks has… [checks notes]… 116 releases already.

Citizen Astronomy (CAst)
by ÖgetayKayali
https://github.com/OgetayKayali/citizen-astronomy

Every clear night, amateur telescopes around the world capture photons that professional observatories never will -- the right patch of sky, at the right moment, with enough patience to notice something change. Citizen Astronomy turns those images into science.

CAst is a desktop application (Windows installer primary; unsigned macOS .app zip available for alpha testers) that takes folders of FITS and XISF images and gives you the tools to measure variable stars, discover moving asteroids, build Hertzsprung-Russell diagrams, and explore the sky -- all from one guided interface, no command-line scripting required.

Please read more details in ALT-Texts of images. These images are just a few examples of the sophisticated use-cases of this software!
Another nice example:

Differential Photometry Example of produced light curves in Citizen Astronomy (CAst) Open a folder of time-series images, and CAst scans your frames, identifies field stars through Gaia DR3 and VSX catalogs, performs aperture photometry with adaptive FWHM-scaled apertures, and produces differential light curves. Fit periods with Lomb-Scargle, refine comparison stars, bin for signal-to-noise, and export science-ready AAVSO reports.

Alt...

Sky Explorer Open any plate-solved image and turn it into an annotated field census. CAst queries SIMBAD, Gaia DR3, VSX, the NASA Exoplanet Archive, and JPL Horizons for objects inside your footprint, then overlays them on the frame with a searchable results table. Switch object-type modes from Simple deep-sky classes to Scientific SIMBAD codes, compare against DSS or Hα survey cutouts with an interactive divider, mark magnitude reach with Mag Limit, add manual annotations, export stills or comparison animations, and build size-aware object collages from catalog angular sizes.

The Sequencer: Detect one-dimensional sequences in complex datasets

The Sequencer reveals the main sequence in a dataset if one exists. To do so, it reorders objects within a set to produce the most elongated manifold describing their similarities which are measured in a multi-scale manner and using a collection of metrics. To be generic, it combines information from four different metrics: the Euclidean Distance, the Kullback-Leibler Divergence, the Monge-Wasserstein or Earth Mover Distance, and the Energy Distance. It considers different scales of the data by dividing each object in the input data into separate parts (chunks), and estimating pair-wise similarities between the chunks. It then aggregates the information in each of the chunks into a single estimator for each metric+scale.

Alt...

Shuffled image rows The Sequencer reorders the objects in the input dataset according to a detected sequence, if such sequence exists in the dataset. A good example of a perfect one-dimensional sequence is a natural image: the rows within a natural image form a well-defined sequence. Therefore, we can shuffle the rows in a natural image, and apply the Sequencer to the shuffled dataset. The following figure shows the result of applying the Sequencer to a shuffled natural image. The left panel shows the original image. The middle panel shows the same image after we have shuffled its rows. The shuffled image serves as the input dataset to the Sequencer, where each row is considered as a separate object. The output of the Sequencer is shown in the right panel, where we reordered the rows according to the detected sequence. The Sequencer successfully identified the one-dimensional trend spanned by the different rows.

CLUES: Clustering tool for analyzing spectral data

CLUES (CLustering UnsupErvised with Sequencer) analyzes spectral and IFU data. This fully interpretable clustering tool uses machine learning to classify and reduce the effective dimensionality of data sets. It combines multiple unsupervised clustering methods with multiscale distance measures using Sequencer (ascl:2105.006) to find representative end-member spectra that can be analyzed with detailed mineralogical modeling and follow-up observations. CLUES has been used on Spitzer IRS data and debris disk science, and can be applied to other high-dimensional spectral data sets, including mineral spectroscopy in general areas of astrophysics and remote sensing.

3ML: Framework for multi-wavelength/multi-messenger analysis

The Multi-Mission Maximum Likelihood framework (3ML) provides a common high-level interface and model definition for coherent and intuitive modeling of sources using all the available data, no matter their origin. Astrophysical sources are observed by different instruments at different wavelengths with an unprecedented quality, and each instrument and data type has its own ad-hoc software and handling procedure. 3ML's architecture is based on plug-ins; the package uses the official software of each instrument under the hood, thus guaranteeing that 3ML is always using the best possible methodology to deal with the data of each instrument. Though Maximum Likelihood is in the name for historical reasons, 3ML is an interface to several Bayesian inference algorithms such as MCMC and nested sampling as well as likelihood optimization algorithms.

AutoWISP

Kaloyan Penev, Angel Romero and S. Javad Jafarzadeh have developed a software pipeline, AutoWISP, for extracting high-precision photometry from citizen scientists' observations made with consumer-grade color digital cameras (digital single-lens reflex, or DSLR, cameras), based on their previously developed tool, AstroWISP. The new pipeline is designed to convert these observations, including color images, into high-precision light curves of stars.

"We outline the individual steps of the pipeline and present a case study using a Sony-alpha 7R II DSLR camera, demonstrating sub-percent photometric precision, and highlighting the benefits of three-color photometry of stars. Project PANOPTES will adopt this photometric pipeline and, we hope, be used by citizen scientists worldwide. Our aim is for AutoWISP to pave the way for potentially transformative contributions from citizen scientists with access to observing equipment."

This is the resulting phase-folded lightcurve for WASP-33 b exoplanet transit, observed by Project PANOPTES (blue points and circles), TESS (red points), and theoretical light curve based on best known system parameters (green curve). The raw PANOPTES-DSLR measurements, originating from the 4 color channels of 4 cameras in Hawaii (Mauna Loa observatory) and California (Mt Wilson) are shown as blue points. The blue points are binned in time to create the blue circles and corresponding error bars. Note that the scatter in TESS points is not instrumental, but rather it is intrinsic variability in the host star, which is a member of the delta-Scuti class of variable stars.

Alt...

The scatter (median absolute deviation from the median) of the individual channel lightcurves of PANOPTES observations of a 10 × 15 degree field centered on FU Orionis, with each of their corresponding image colors (RGGB). We see that AutoWISP enables a few parts per thousand photometric precision per exposure even from images with Bayer masks, significantly outperforming prior efforts. Even individual color channels result in better than 1% photometry per 2 min exposure.

PIRATES
(Polarimetric Image Reconstruction AI for Tracing Evolved Structures)
uses machine learning to perform image reconstruction.

It uses MCFOST to generate models, then uses those models to build, train, iteratively fit, and evaluate PIRATES performance.

Optical interferometric image reconstruction is a challenging, ill-posed optimization problem which usually relies on heavy regularization for convergence. Conventional algorithms regularize in the pixel domain, without cognizance of spatial relationships or physical realism, with limited utility when this information is needed to reconstruct images. Here we present PIRATES (Polarimetric Image Reconstruction AI for Tracing Evolved Structures), the first image reconstruction algorithm for optical polarimetric interferometry. PIRATES has a dual structure optimized for parsimonious reconstruction of high fidelity polarized images and accurate reproduction of interferometric observables. The first stage, a convolutional neural network (CNN), learns a physically meaningful prior of self-consistent polarized scattering relationships from radiative transfer images. The second stage, an iterative fitting mechanism, uses the CNN as a prior for subsequent refinement of the images with respect to their polarized interferometric observables. Unlike the pixel-wise adjustments of traditional image reconstruction codes, PIRATES reconstructs images in a latent feature space, imparting a structurally derived implicit regularization.

The performance of PIRATES with signal to noise consistent with recent VAMPIRES NRM data, with no algorithmic treatment to constrain the influence of noise. Visibilities and closure phases with injected noise and corre- sponding error bars are plotted in columns 1 and 2. Stage 1 (CNN) does a good job of a moderate resolution and low noise reconstruction of the ground truth (top row, columns 3-5), however, significant amounts of noise are introduced into the images during the iterative fitting (middle row, columns 3-5). The ground truth images are displayed in the bottom row, columns 3-5.

nazgul is a joint effort by:

* J. Michael Burgess
* Ewan Cameron
* Dmitry Svinkin

https://github.com/grburgess/nazgul
Nazgul is a framework for performing GRB localization via fitting non-parametric models to their data time-series and computing the time delay between them. It is currentrly built upon the magic of Stan and implements a parallel version of non-stationary Random Fourier Features. The idea is get away from heuristic methods such as cross-correlation which do not have a self-consistent statitical model.

The idea is that satellites throughout the Sol system observe gamma-ray bursts at different times due to the finite speed of light. This creates a time delay in their observed light curves which can be used to triangulate the gamma-ray burst position on the sky. These triangulation create annuli or rings on the sky which Nazgul searches for so that it, in the darkness, it can bind them to a location on the sky.

I didn't see the point of #Jupyter notebooks at first, but it's a pretty good way to work on #Python code, if you're doing a lot of fiddly interacting with remote systems or working on processing images at all.

Like, I've got an old phone mounted in a spot where it's not visible in the room, pointed out at the backdoor where the doggos come and scratch to get in. The idea is to have it notify us both when they get to the door, so we can train them to just sit and wait.

The phone is running Android IP Camera, a basic app that streams the camera of your choice in an easily-polled way. It was fairly easy to sort out how to grab a frame from it, but then it needed rotating and a bit of cropping, and being able to modify the params and then just hit the Run button and get the new image, it sped up the process by many units of time.

I built a small tool to automate Google Flights searches across different countries and locations, testing whether changing the VPN/IP and Google’s location actually affects flight prices.

Early results are pretty interesting: dozens of tests, different countries and even different IPs, same flight... same price 🤷🏻‍♂️

So if you're wondering how great #RustLang is, let's talk about #mypy. Mypy introduced its own Rust - #Python package, ast-serialize. This package had a deep crate dependency that was broken on PowerPC. The issue was fixed a month ago but everything is still blocked on a deep chain of dependencies being updated and released.

https://github.com/mypyc/ast_serialize/issues/68

EDIT: yes, I know, it's not Rust, it's Cargo. Because obviously Rust without Cargo makes so much sense for that one project using it.

Remember `build-details.json` (PEP 739)? The file added to #CPython to support cross-compiling extensions?

Well, turns out it gets generated incorrectly when cross-compiling CPython itself 🤦. Let's see if I can fix that…

Miscellaneous notes

(1)
A riddle: why is Python (the programming language) _natively_ suitable for controlling robots?

(2)
There are other qualities by which Python is at least a spiritual descendant of Lisp.
For example, Lisp is the earliest object-based language and Python is also object-based.
In Python, `==' is to `is' as in Lisp `equal' is to `eq'.
There is a long list of details, such as Python's `import' being similar to Lisp's `require' or `type' being similar to `type-of'.
Type declarations are optional.
Python's doc-strings are syntactically like Lisp's doc-strings.

Top Four funniest things about Python (language by Guido):
4. IDLE IDE named after Eric.
3. import antigravity
2. import turtle; turtle.reset(); turtle.forward(100); whee!
1. How incredibly irate whitespace indenting makes faux-traditional programmers (knows of Algol but is unaware of/disrespects FORTRAN).
#python

mini #python quiz:

how many elements in this set?

{1.0, True, 1, complex(1,0)}

and what is/are their type(s)?

@mgorny The good news is that was merged in 2024 but never actually released, so this change only affects those using unreleased source directly? And it's been archived on PyPI, so perhaps find a replacement.
#Python #flit

@screwlisp I think there's a confusion of two things there, the LISP compiler:
https://en.wikipedia.org/wiki/CMU_Common_Lisp

Guido's Python is unrelated, came out of his ABC language (which I played with a bit on the ST in college) & Monty Python jokes. It's not a snake.
#python

While I am still AWOL myself, I got an interesting piece of trivia from the guy who runs NZ's #python stuff.

a. Pre- #lisp, the python program was so named "because it could swallow the whole pig". (!).

b. EDITED in 1994 python (scripting) had "lisp influenced" lambda and map/reduce/filter added to its standard library, and later removed.

Though his source was "he googled it" so I dunno, I don't partake in that personally.

Today in things that couldn't have aged well:

"Unpin flit-core dependency" 2 years ago without actually updating the metadata to use the newer pyproject.toml format.

#Python #flit

Me after laboriously backporting #Python 3.15 fixes to #Django 6.0.x in #Gentoo: "oh, nice, the patchset applies cleanly to 5.2.x as well."

And today, I have to laboriously backport another patch to 6.0.x, and it turns out the backport doesn't apply cleanly to 5.2.x, so I have to laboriously backport it there as well.

I honestly *hate* Django Python version support policy. Shifting all the burden downstream.

Setting up a Raspberry Pi to run my Bluesky bot because #Pipedream keeps failing with an enigmatic "could not execute step" error and I'm being reminded what an absolute nightmare #Python/pip is to get set up

BTW I had account on identi.ca, which was StatusNet powered (I believe).

Yes, and it should not be implemented in Ruby or PHP or something like that. I have seen one online discussion forum being rewritten from PHP to Rust few years ago, and the improvement in responsiveness of the web platform was amazing. (I do C, not Rust, but C is too oldschool now, and the performance penalty of Rust is minor, probably not noticeable at all)

Friendica and its descendants are written in PHP. They may not be the fastest (even though what bogged down early Friendica were its heavyweight federation connectors to everywhere, especially the one for Facebook that came in 2011). Mike either discarded or rewrote these when he rewrote Red. But they happily run on a run-of-the-mill LAMP stack.

Mastodon is written in Ruby on Rails. Hubzilla runs circles around it in terms of performance per account/channel, and that has to say something. The only thing that managed to top this was early diaspora*, written in Ruby on Rails for Mac with MongoDB as the database system.

The *omas are built in Elixir. Granted, they're utter featherweights, especially considering their features. They're legendary for their low server impact. Then again, Pleroma apparently is spaghetti code straight from hell. Its own devs often don't have a clue where to go look for bugs, much less how to fix them. (Miraculously, the Akkoma devs do manage to get ride of quite a number of them.)

The *keys are built in TypeScript and Vue.js. I guess one reason why Misskey is infamous for having so many forks and forks of forks is because there are tons of people who can code in JavaScript, the primary mobile programming language.

Iceshrimp.NET is a still very incomplete "rewrite" of old Iceshrimp in C#. It was largely tackled to get rid of all those nasty bugs inherited from Misskey that even Misskey doesn't manage to get rid of. I've heard quite some outcry: Iceshrimp.NET is a sell-out to Microsoft. I guess whoever uttered that didn't go check who owns TypeScript.

PieFed is a dead giveaway: Python. And PieFed makes more headlines in the Threadiverse for server politics than for its underlying technology, except that Lemmy pales in comparison.

GoToSocial is a dead giveaway, too: Go. And it was one of the first Fediverse server applications to not come with a Web UI. Those who use it for a single-user server often don't even bother installing one and use some Mastodon app or other instead. Besides, why drag around a Web UI if there are much better third-party Web UIs than whatever you could whip up?

"It abstracts away all of the memory management, the hardware architecture and stuff for you when you write in #Python."
That's how most people got into #spreadsheet too back when coding outside of tech people is still too far away.

Zero days since I've discovered a random #CPython bug that triggers in very specific circumstances and I don't really have time to report it, nor can expect anyone to do it for me.

This time it's a test failure and refcounts being broken while running fastjsonschema's test suite on #Python 3.15 freethreading with pytest's --junit-xml option enabled 😱. And of course removing --junit-xml makes all tests pass.

EDIT: and of course I cannot reproduce outside Portage. Yet inside, it reliably crashes every single time.

EDIT 2: couldn't reproduce at all the next day.

In the meantime, #GitPython, the package that used to be dead (because the author is busily working on their next great thing) is now slopping out 4 "security" releases a week, as their #slop machine is busily fixing unintended variable expansion in every single URL they call. Unfortunately, they probably don't have enough tokens to fix them all at once, so instead all downstreams have to deal with the churn of endless security releases. Or the brain to figure out that maybe they could just disable variable expansion by default and solve them all at once.

It's truly a great time to be a #Python packager.

#NoAI #NoLLM

Also, zero days (well, minus a lot of days because I've been slacking) since a random #Python package got a new #NIH dependency on another Python package which is actually a "fastest" #RustLang package which cannot be built because the author thinks it a great idea to require a nightly Rust compiler.

…and of course it's full of "unsafe" calls. Because Rust is obviously such a great language for making secure code.

So I wanted to unbundle #uChardet from #cChardet #Python package.

It didn't build against system uchardet 0.0.8. So I've checked, and it turns out cchardet is using some old patched fork of uchardet. Ugh.

Fortunately, upstream added the "missing" function too, with a different API (that's not really a problem), but they didn't make a release in 4 years. Ugh.

I could at least replace the old patched uchardet with upstream uchardet, right? Except now I'm getting test failures over misdetected encodings. 0.0.8 works fine there. Though the particular test doesn't look very realistic (note all the repetitions):

The state of #Python ecosystem right now: almost everything is slop. Some projects are complete vibe-coded slop (autobahn, chardet, cryptography). Some projects are disguised slop ("Coding agents shouldn't co-author themselves.")

There is only a handful of human projects left (Flask being one bright example). And they're being killed. They're being killed by the neverending slew of slop pull requests. They're being killed by all their dependencies becoming slop. They're being killed because this whole ecosystem has became such a complete cesspit that you have zero motivation to do anything.

EDIT: and honestly, this is only going to get worse. When you kill the incentive to work on projects, you only get more slop. Maintainers give in, and more projects become slop. Or they give up, and projects get forked unto slop.

I wish #mypy would slow down with adding new features to mypyc, and instead focused on fixing the train wreck that mypyc is right now (since 2023 at least).

I love SciFi in all forms, especially #StarTrek and #DoctorWho.
No tolerance for discrimination of any kind.

so, some people may wonder why i do not maintain BSID and BSID-JS as often as i probably should. that's because of lack of partisipation. basically my rule is that if you want a feature within it, weather you are #blind, or whatever you are, doesn't matter, it's your job to implement, weather it be by fingers on the keyboard with your #python or #javascript/wrangler, and send out a pull request, or AI generated code. seams not many want to do that, and because of suuch, i've stopped supporting it for now. of corus, there is 1 exception, and that is if there's a new implementation in gemini or CF workers AI that physically prevents the image descriptions from getting out, or a change in discords API, in that case i will patch it. other than that, if you, say, have a flashier model yyou want deployed, etc etc, you code it yourself.

And the next big blocker for #Python 3.15 in #Gentoo is time-machine. Which is obviously broken. There's a patch but it's #slop and complex, and it's sitting for 3 months already with no reply. Because obviously patching CPython internals is so much a better idea than freezegun ever were. All these time-based tests need all the ricing you can get; portability doesn't matter.

#Python Hypothesis package now requires #RustLang. This is a scale of reverse dependencies I can't handle. I guess this means it's the end of WD40 profiles on #Gentoo, and therefore the end of support for Alpha, ARM<v6, HPPA, M68k, i486 and some other random subsets of architectures and profiles. Thanks for all the fish, etc.
