I need to extract certain information from a bunch of images. I'm a Python developer, but know little about this niche. Can somebody suggest particular toolkits to start with?

The problem: The placement of flippers on pinball machines has a rich history. There are thousands of different pinball machines. I would like to identify broad trends and turning points. So I'd like to be able to process photos like this in bulk, spot the flippers, and record their locations relative to the rest of the playfield: ipdb.org/showpic.pl?id=20&picn…

I know how to get the raw data (lists of pinball machines, collection of images) but the part I don't know how to tackle is the image processing (selection of best playfield image, compensating for photographer variation, finding the flippers, extracting their position and angle).

In my ongoing efforts to enhance the python music ecosystem, I have made pypi.org/project/music-basslin… - Adding examples currently... 😀

#Python #Music

Bam! Another in my series of musical creativity #Python classes:

pypi.org/project/music-tonnetz…

Apparently, the nerdiest of chord transformations. Two of the apps on a synth module of mine have Tonnetz things. Ha 😁

This relies on my port of the excellent #Perl module, metacpan.org/dist/Music-NeoRie…

```python
from music_creatingrhythms import Rhythms
from music_drummer import Drummer

r = Rhythms()
beats = 16
kick = ''.join([str(n) for n in r.euclid(2, beats)])
snare = ''.join([str(n) for n in r.rotate_n(4, r.euclid(2, beats))])
hihat = ''.join([str(n) for n in r.euclid(11, beats)])

d = Drummer()
d.set_bpm(100)
d.set_ts()
for _ in range(8):
d.pattern(patterns={ 'kick': kick, 'snare': snare, 'hihat': hihat })
d.sync_parts()
d.show(format='midi')
```

#Python #MIDI Euclidean #drums

New musical #Python package in the house! Today it's pypi.org/project/music-creatin… ported from the c code, that is a companion to the book, abrazol.com/books/rhythm1/ "Creating Rhythms" by Stefan and Richard Hollos.

With it, you can do a bunch of combinatorial things to make rhythmic patterns, like the `euclid(m, n)` method, for instance.

Woo! 😁

I've coded-up a really cool #Python class: pypi.org/project/chord-progres… - It is a network transition, musical chord progression generator. Like a Markov chain thing. 😀

Dig it!

I have created a simple #Python drummer: pypi.org/project/music-drummer…

It is not a "drum machine," but rather the essentials to play drum grooves, instead of a boring metronome. 😀

This is a work-in-progress, and more features may be added yet, like being able to interact with existing music21 scores, for one.

Guess I'll make a #node #npm package to mirror my #python pypi.org/project/chess-coverag… and #perl metacpan.org/pod/Chess::Rep::C…

I love Perl. 💜 It's the language I know best, at the moment, because I have been using it since 1995, as a career Perl programmer.

However, I rather like Ruby, because it's very Perlish, has first class PCRE, and is concise and clean, and DWIM. Most importantly, it has a cleaner OOP syntax, with a "class" keyword built-in, unlike Perl, whose OOP is a bolted-on afterthought, bless her dirty soul.

Python is okay, but it's built-in support for List Comprehension is super awesome! List Comprehensions make code even more elegant and pithy than Perl, by natively providing a construct that is roll-your-own in Perl, like OO.

Also, Python's NumPy and SciPy libraries gave it an early lead in the field of Machine Learning, a place that should rightfully have belonged to Perl, notorious for how easily it can slice, dice and munge text.

#perl #ruby #python #programming #programminglanguages #machinelearning

Well, count me among the ranks of the laid-off tech workers. I've done plenty of #perl for a couple lifetimes. But for the past years have done a lot of #python, #node and #typescript as well. Check out github.com/ology for more exciting details! 😁

Today I was reading about quantum computers only being able to do math that is reversible.

That means they cannot do exponents in the standard way, because a positive exponent is impossible to unwind, as the result could be positive or negative.

210 = -210 = 256

But there is a way to do it that quantum computers are fine with. Here is my python code example of it.

You'll recognize the weird nth_fib from a previous post of mine. So you could argue that this is doubly-weird.

Try it out, and let me know if you have any ideas or improvements for bibonacci_exponentiation(). Otherwise, use it to learn a new trick (as I did today).

You can cut/paste the code from the alt text so you don't have to bring out your magnifying glass to type it out manually.

Bonus if you can explain why it works.

Very thoughtful post.

As for #Perl, it hardly “stopped at version 5.” (See @shiar’s summary of changes from Y2K’s 5.6 to last year’s 5.38: sheet.shiar.nl/perl.) There simply hasn’t been major breaking changes, unlike, say, #Python.

The community also lacks consensus on the marketing value of a new major version. Some software releases just merrily keep incrementing that number to draw attention and create FOMO, semantic meaning be damned.

A few thoughts on Programming languages

Just a few thoughts on programming languages that have been rattling around in my head this week, but which don’t each merit a full blog post. The main theme is that the culture behind each programming language leads to some interesting choices, as is the case with spoken languages.

This week I started learning how to program in Rust. Even though I’m using the project-based Command-Line Rust to learn, the author still went with the traditional “Hello, world!” project for the first intro to the language. I was also working on a Go project last week and so it immediately stood out to me that (at least as taught by this author) Rust has the print! macro that allows you to succinctly print to the command line. By contrast, Go requires importing fmt before you can print. This was the first topic that was swirling around in my head this week. What makes language designers choose whether printing output (one of the most basic things a program can do) is built-in or requires an import. I even remember back when I was learning Java in undergrad (I think it was Java 1.8, but I don’t remember) we had to use the savitch library just to get program input (another very basic computer program concept). As I thought about it, I wondered if it has to do with thoughts around compilation and whether the language designers think you’re mostly making user-interactive programs or libraries? It makes sense to me that scripting languages like Python, Ruby, and Perl would have print built-in since you always have to have the interpreter along with you, so all the basics should be there. (The original Batteries Included Python promise, for example) But perhaps the Go developers thought you wouldn’t always be printing to the command line so a more efficient binary could be compiled by forcing you to import the functionality? I’m not entirely sure.

The next thing I started thinking about, again due to learning Rust, was the mutability of variables. In most languages I’ve come across (I think all, except Haskell) all variables are mutable by default. It almost seems pointless to have a non-mutable variable. I understand why many languages have the concept of a “contanst” modifier/keyword. Unlike normal variables, THIS ONE does not change. But the opposite seems so weird since most of what we often do in programming involves changing the value in a variable. Perhaps as I learn more about Rust, I’ll understand their reasoning, but this seems completely backwards to me.

Both Rust and Golang use structs to organize variables where Ruby, Python, and Java use objects. But when both Go and Rust allow you to “attach” methods/functions to structs – is there a true distinction between object-oriented programming and struct-based programming? It seems like it’s just semantics (in the generic sense of the word) – at least at the level at which I program. The only difference I can see is that structs don’t have inheritance, although Go’s “types” solve some of the same problems.

Today’s (the day I’m writing this, not the day it’s going to be posted) shower thought was about programming language versions. On one end you have Java (I think now on version 22) and C# (now at version 12). On the other you have Python and Ruby (both at version 3). Perl essentially stopped at 5 with Perl 6 evolving into Raku. I don’t know what Java is up to. But I think C# is actually using the versions correctly – I’ve heard that each version introduces completely different ways of doing things and that the way you program C# depends strongly on when you jumped in. This is why Python is probably never moving to v4 unless they need to make some kind of huge change. Rust is an outlier with year-based versions. I guess that’s fine, but doesn’t tell you anything like a proper semantic versioning could.

Finally, I know that Rust is the newest of all the programming languages I’ve learned, but I really love how new projects are started. Python isn’t horrible, but it’s currently suffering from a lots of ideas, none of which has complete market share. You could do a simple virtual environment or you could do a more complex virtual environment/lock file situation with Poetry. (And there are about another half dozen variations on these two themes) But Rust….Rust deserves a chef’s kiss. When you start a new project with “cargo new project-name”, not only does it set up your directory structure, but it does a whole bunch of great setup tasks. It creates your Cargo.toml file (with Python, which only really started supporting toml files at the project level a few years ago, you need to look at documentation to figure out what goes in there) so that you have all the basics in there already. But it doesn’t stop there! It also, in a nod to modern programming, creates a git repository AND a gitignore file. It’s a thing of beauty. I would absolutely love for Python to move in this direction officially (not through a random user choice) for their defaults. Even “go mod init” could benefit from setting up a git repo and a git ignore (since the toml is not how Go works – I think they would probably best set up a README.md since Go’s default packaging is through git repos).
