@prologic Hmm, good question. I haven’t checked the market, I got mine from someone I know. But to be honest, I’d suspect that buying a used one is actually your best shot, because there is virtually no market for these devices anymore, meaning new ones are very, very expensive. 🫤

Speaking of manpages:
⤋ Read More
@kat@yarn.girlonthemoon.xyz On the one hand, all these programs have a very long history and the technology behind manpages is actually very powerful – you can use it to write books:
https://www.troff.org/pubs.html
I have two books from that list, for example “The UNIX programming environment”:
https://movq.de/v/c3dab75c97/upe.jpg
It’s a bit older, of course, but it looks and feels like a normal book, and it uses the same tech as manpages – which I think is really cool. 😎
It’s comparable to LaTeX (just harder/different to use) but much faster than LaTeX. You can also do stuff like render manpages as a PDF (man -Tpdf cp >cp.pdf) or as an HTML file (man -Thtml cp >cp.html). I think I once made slides for a talk this way.
On the other hand, traditional manpages (i.e., ones that are not written in mandoc) do not use semantic markup. They literally say, “this text is bold, that text over here is italics”, and so on.
So when you run man foo, it has no other choice but to show it in black, white, bold, underline – showing it in color would be wrong, because that’s not what the source code of that manpage says.
Colorizing them is a hack, to be honest. You’re not meant to do this. (The devs actually broke this by accident recently. They themselves aren’t really aware that people use colors.)
If mandoc and semantic markup was more commonly used, I think it would be easier to convince the devs to add proper customizable colors.

Ultimately, Go sits in the sweet spot on the complexity vs performance chart:
- Minimal syntax & concepts → low learning curve
- Compiled speed → high throughput
- Built-in CSP concurrency → scalable by default
See Rob Pyke’s presentation on Expressiveness of Go
New (February 2025) paper, https://cms.mgt.tum.de/fileadmin/mgt.tum.de/faculty_and_research/mppe/39_Nora_von_Ingersleben-Seip_How_the_European_Union_Fell_Out_Of_Love_With_Open-Source_Software.pdf , describes “How the European Union Fell Out of Love with Open-Source Software”:
“A coalition of determined open-source software (OSS) advocates and a handful of technology experts working in the European Commission set out in 2004 to end Microsoft’s monopoly. They almost succeeded. This article reveals how they managed to change the EU’s software policies, made Microsoft lobbyists work overtime - and in the end, and despite their best efforts, could not withstand the power of proprietary companies’ lobbying campaigns.
Drawing on the Multiple Streams Framework, the article explains the European Commission’s decision to promote OSS and open standards in 2004, and its puzzling decision to reverse course just a few years later, in 2010, despite its unchanged rhetoric about the benefits of openness. The analysis reveals three key factors that drove the changes in the EU’s policies.
In 2004, OSS advocates managed to frame the EU’s dependency on proprietary software as a problem – and the promotion of OSS and open standards as the solution.
In 2010, #Microsoft and other proprietary companies used their existing connections in Brussels to sow doubt about the maturity and cost of #OSS among #EU policymakers.”
25 years later we’re where we started.

When will the flat UI craze end? Can I get my buttons, scrollbars, and toolbars back, please?
⤋ 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
passone 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. :-)

@xuu@txt.sour.is Thanks for the link. I found a pdf on one of the authors’ home pages: https://ahmadhassandebugs.github.io/assets/pdf/quic_www24.pdf . I wonder how the protocol was evaluated closer to the time it became a standard, and whether anything has changed. I wonder if network speeds have grown faster than CPU speeds since then. The paper says the performance is around the same below around 600 Mbps.
To be fair, I don’t think QUIC was ever expected to be faster for transferring a single stream of data. I think QUIC is supposed to reduce the impact of a dropped packet by making sure it only affects the stream it’s part of. I imagine QUIC still has that advantage, and this paper is showing the other side of a tradeoff.
