* KMail – e-mail client
* Okular – PDF viewer
* Gwenview – image viewer
* Dolphin – file browser
* KWallet – password manager (I want to check out
pass one day. The most annoying thing is that when I copy a password, it says that the password has been modified and asks me whether I want to save the changes. I never do, because the password is still the same. I don't get it.)* KPatience – card game
* Kdenlive – video editor
* Kleopatra – certificate manager
Qt:
* VLC – video player
* Psi – Jabber client (I happily used Kopete in the past, but that is not supported anymore or so. I don't remember.)
* sqlitebrowser – SQLite browser
Gtk:
* Firefox – web browser
* Quod Libet – music player (I should look for a better alternative. Can't remember why I had to move away from Amarok, was it dead? There was a fork Clementine or so, but I had to drop that for some unknown reason, too.)
* Audacity – audio editor
* GIMP – image editor
These are the things that are open right now or that I could think of. Most other stuff I actually do in the terminal.
In the past™, I used the Python KDE4 bindings. That was really nice. I could pass most stuff directly in the constructor and didn't have to call gazillions of setters improving the experience significantly. If I ever wanted to do GUI programming again, I'd definitely go that route. There are also great Qt bindings for Python if one wanted to avoid the KDE stuff on top. The vast majority I do for myself, though, is either CLI or maybe TUI. A few web shit things, but no GUIs anymore. :-)*
> Although, most software I use is decentish in that regard.
Is that because you mostly use Qt programs? 🤔
I wish Qt had a C API. Programming in C++ is pain. 😢

I just noted today that JetBrains improv^Wcompletely fucked up their new commit dialog. There's no diff anymore where I would also be able to select which changes to stage. I guess from now on I'm going to exclusively commit from only the shell. No bloody git integration anymore. >:-( This is so useless now, unbelievable.
Joking aside, let's see how it works in the wild!

Also, it is very easy to filter or ignore it.

I'm going to try out something, let's see what happens... next Saturday (2025-03-29) and possibly on some other Saturdays after that. I'm going to host an online space where I show something about Creative Coding with #Python and #py5. I'm calling it "Python Creative Coding Free Walking Tour". I'll also do some "py5 Office Hours", Q&A and on-boarding.
It will be free, and I'll accept donations, just like the free walking tour we have showing off nice spots of São Paulo for tourists. I hope it will be even better than that: as I studied architecture I find the tour guide's explanations a bit over the top and sometimes missing the point, but maybe mine will also be an over the top creative coding tour, who knows? you'll have to judge by yourselves.
The first, "walking tour" part will be from 11:00AM BRT (UCT -3) to 12:00 and then, the second, "office hours" part, will be from 12:15 to 13:00, when people will be able to ask me anything about py5 and I'll try to answer to the best of my knowledge, it will also be an opportunity to get help setting up your tools/environment in order to take your first steps drawing with code.

Is it working now?
I'd say again that perhaps the DMs could be stored in another .txt, but anyway I'd like to try it.
More news coming soon.

A pointer is an indirection. At a lower level, when you have some chunk of memory, you can have some actual values sitting in there, ready for direct use. A pointer, on the other hand, points to some other location where to look for the values one's actually after. Following that pointer is also called dereferencing the pointer.
I can't come up with a good real-world example, so this poor comparison has to do. It's a bit like you have a book (the real value that is being pointed to) and an ISBN referencing that book (the pointer). So, instead of sending you all these many pages from that book, I could give you just a small tag containing the ISBN. With that small piece of information, you're able to locate the book. Probably a copy of that book and that's where this analogy falls apart.
In contrast to that flawed comparision, it's actually the other way around. Many different pointers can point to the same value. But there are many books (values) and just one ISBN (pointer).
The pointer's target might actually be another pointer. You typically then would follow both of them. There are no limits on how long your pointer chains can become.
One important property of pointers is that they can also point into nothingness, signalling a dead end. This is typically called a null pointer. Following such a null pointer calls for big trouble, it typically crashes your program. Hence, you must never follow any null pointer.
Pointers are important for example in linked lists, trees or graphs. Let's look at a doubly linked list. One entry could be a triple consisting of (actual value, pointer to next entry, pointer to previous entry).
_______________________
/ ________\_______________
↓ ↓ | \
+---+---+---+ +---+---+-|-+ +---+---+-|-+
| 7 | n | x | | 23| n | p | | 42| x | p |
+---+-|-+---+ +---+-|-+---+ +---+---+---+
| ↑ | ↑
\_______/ \_______/
The "x" indicates a null pointer. So, the first element of the doubly linked list with value 7 does not have any reference to a previous element. The same is true for the next element pointer in the last element with value 42.
In the middle element with value 23, both pointers to the next (labeled "n") and previous (labeled "p") elements are pointing to the respective elements.
You can also see that the middle element is pointed to by two pointers. By the "next" pointer in the first element and the "previous" pointer in the last element.
That's it for now. There are heaps ;-) more things to tell about pointers. But it might help you a tiny bit.______________________________________________
@prologic I see this with the scouts. Luckily, not at work. But at work, I'm surrounded by techies.
@movq Oh my goodness! I'm so glad that I don't have to deal with that in my family. But yeah, I guess you're onto something with your theory. This article is also quite horrific. O_o
fun run... broke it up in 5km segments. around 14 miles in started to just take it a bit easier because the legs just got a bit tired. pretty good for crap sleep and/or rest.

People are less and less exposed to “low-level” details like this. There was also this story in 2021 about the concept of a “file”: https://www.theverge.com/22684730/students-file-folder-directory-structure-education-gen-z

I don’t intend to do much with Win95. I just want to be able to boot it, if I want to check how certain things worked or looked in that version. The purpose of this really is to be an archeological digsite.
