New GitHub, PyPI Policies Hope to Boost Supply Chain Security
“GitHub and the Python Package Index (PyPI) have introduced new policies meant to boost supply chain security,” reports SecurityWeek, “by preventing the fast propagation of poisoned package versions and the poisoning of old and long-stable releases.”

Why.

Python’s numeric types complex, float and int are not subtypes of each other, but to support common use cases, the type system contains a straightforward shortcut: when an argument is annotated as having type float, an argument of type int is acceptable; similar, for an argument annotated as having type complex, arguments of type float or int are acceptable.

@movq@www.uninformativ.de The nice thing about properties is that you can compute and cache things on the fly at first attempt and also ensure validation for writing. But like you said, since it’s not obvious that reading or writing might do some more things, it’s strongly advised to avoid doing expensive stuff disguised as properties.

I reckon the vast majority of property use cases is to provide read-only access. At least that was my impression when I was doing a lot more in Python.

Personally, I think that this just reads a lot nicer:

oink.my_property
oink.my_property = 42

Than:

oink.get_my_property()
oink.set_my_property(42)

Btw, any field access is implemented using method calls. I might be wrong, but I believe there’s always __getattr__ and __setattr__ involved. 8-)

I trip over this in our code at work all the time.

Python has this concept of “properties”:

class Oink:
    def __init__(self):
        self._foo = 3

    @property
    def my_property(self):
        return self._foo


a = Oink()
print(a.my_property)

my_property() is a method but it can be used as if it were a field.

This can also be used to define a setter:

class Oink:
    def __init__(self):
        self._foo = 3

    @property
    def my_property(self):
        return self._foo

    @my_property.setter
    def my_property(self, value):
        self._foo = 123 * value

Because, for some reason, Python people don’t like getters and setters. Instead, they hide it behind a property.

The result is, when you read this:

a.my_property = 5
print(a.my_property)

You have no idea that this actually calls a method.

@movq@www.uninformativ.de My grief with Java is that it’s sooo verbose. Sure, all the enterprise garbage makes it a hell lot more terrible, but even regular Java feels always so lengthy. And back in the days when I was using it daily, I missed so many convenient things in the stdlib after having experienced Python’s “batteries included”. Not sure if or how recent Java versions caught up.

I really think I should go back to Java.

Writing programs in Python is so exhausting. I want a compiler and I want static typing. No, linters and type checkers and IDEs are not good enough. Compilers catch way more errors in advance.

Rust is also exhausting. They’re constantly adding language features and, at the same time, the runtime library remains tiny and you need 3rd party libraries for everything. Many of those are still at version 0.x (SemVer!) and you can’t rely on anything. Often times, you need the latest Rust nightly compiler.

Go is … I don’t like it. And huge binaries.

I like C as a language, but it’s too fragile. I want to have a proper HashMap every now and then.

None of the above have good GUI libraries, at least not on Linux.

And then there’s Java. This is my fractal renderer that I wrote over 17 years ago:

https://movq.de/v/fcd3c4e557/vid-1784121825.mp4

It’s fast. It has a GUI with custom widgets and those weren’t even hard to make. It still works without changing a single line of code. The source code files have timestamps from 2009 and I just noticed that the JAR file I’m using in the video was compiled in 2010.

Java as a language is relatively easy to learn and to master. There are few surprises. The source code organization with packages is good. Java API docs are clear and well written.

The JVM ramp-up times have improved considerably:

https://movq.de/v/e7314e521e/vid-1784121998.mp4

This isn’t like the Dark Ages anymore. Might even be usable for some CLI tools.

The only thing where Java really sucks is anything close-ish to the kernel. Try issuing an ioctl() … I couldn’t have made my TUI framework in Java, but then again, I wouldn’t have needed to because Swing already exists and it just works.

@lyse@lyse.isobeef.org Besides, have a look at again: When it goes from item 9 to item 10, the indentation of the text (after the number) changes. Pretty ugly. In other words, a table of contents should be a table, not a list like it is at the moment. And that would require me to write my own extension for python-markdown … Probably not worth it.

↳ In-reply-to » @lyse Mhm, yeah, I also think I like date := time.Date(2026, time.June, 19, /**/ 17, 0, 0, 0, time.UTC) the most. 🤔 (My only gripe with this is that it isn’t obvious whether the third 0 is milli-, micro- or nanoseconds. These days it’s probably nanoseconds, but you never know.)

@movq@www.uninformativ.de Right. A Go programmer eventually knows that its nanoseconds precision. Keyword arguments like in Python are just sooo superior to unnamed positional arguments. I wish that Go had them, too.

Boffin Claims Microsoft’s ‘Quantum Leap’ Is Invalid Due To ‘Basic Python Errors’
A peer-reviewed Nature critique argues that Microsoft’s 2025 Majorana quantum-computing breakthrough – and its claim that it could enable “a truly meaningful quantum computer not in decades, as some have predicted, but in years” – is fundamentally flawed.

@lyse@lyse.isobeef.org In what way was KDE 3’s menu organized? KDE 1 is the only KDE version I ever used. 😅 We’re talking about this one, right?

Isn’t Notepad++ and Python cheating!? :-D

Well, Python was certainly already a thing back then, but Notepad++ is from 2003, right. I think I used https://www.wintotal.de/download/proton/ at the time? Maybe? I don’t know. 😅

In my opinion, the KDE 3.5 menu was organized way better than the Windows Start menu. Granted, a typical KDE installation had much more applications to offer, too. So, there was more need to get it right. And it probably was also later in time.

Isn’t Notepad++ and Python cheating!? :-D

Crazy story on the clock’s seconds. I never heard of that before. Neat.

Yeah, UI these days is horrible. (That’s why my own TUIs suck, too!)
