Playing multimedia with Dillo
What if you want to use a web browser like Dillo, which lacks JavaScript support and can’t play audio or video inside the browser? Dillo doesn’t have the capability to play audio or video directly from the browser, however it can easily offload this task to other programs. This page collects some examples of how to do watch videos and listen to audio tracks or podcasts by using an external player program. In particular we will cover mpv with yt-dlp which supports YouTube … ⌘ Read more

@movq@www.uninformativ.de Yeah, most of the graphical applications are actually KDE programs:

• 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. :-)

@lyse@lyse.isobeef.org

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. 😢

@lyse@lyse.isobeef.org (I think of pointers as “memory location + type”, but I have done so much C and Assembler by now that the whole thing feels almost trivial to me. And I would have trouble explaining these concepts, I guess. 😅 Maybe I’ll cover this topic with our new Azubis/trainees some day …)

@prologic@twtxt.net What is “ciwtuau”? I don’t understand, sorry haha

@prologic@twtxt.net So it seems!

#twtxt

@kat@yarn.girlonthemoon.xyz Pointers can be a bit tricky. I know it took me also quite some time to wrap my head around them. Let my try to explain. It’s a pretty simple, yet very powerful concept with many facets to it.

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.

@andros@twtxt.andros.dev @prologic@twtxt.net Exactly. The screenshots of the last few days show it in action. But I do not consider it ready for the world yet. @doesnm@doesnm.p.psf.lt appears to have a high pain tolerance, though. :-)

@andros@twtxt.andros.dev You use your real name as login name, too?

@lyse@lyse.isobeef.org I guess the thing is that usernames are no longer needed for many popular things, like WhatsApp. “Just install the app”, done. When I ran my Matrix server for our family, this was the first thing that people were bummed out about: “Oh, this needs a username and a password? Why doesn’t it just work? That’s annoying.”

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 lost my original Windows 95 CD (and it’s too expensive for my taste to buy on eBay), so I finally sat down and got an old disk image of one of my PCs to work in QEMU.

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.
