Wenn du der Typ Informatiker bist, der von Algorithmen gar nicht genug bekommen kann, gibt es da viele Sachen, bei denen man sich mit diesen Fähigkeiten auch ausserhalb des "praktischen" in digitaler Kunst und Musik austoben kann. Findet man unter Begriffen wie "live coding" oder "creative coding", "Demoszene" (old-school) und noch ein paar anderen. Da findet man oft auch ein paar Gleichgesinnte. Gerade beim live coding ist die Community weltweit gut vernetzt und sehr einsteigerfreundlich ... das Motto ist "embrace the error".

Falls du eher vom Bildschirm wegkommen willst, geh' in dich und frag' dich, was dich so interessiert, such' dir ein komfortables Tempo, und fang' an ...

Was auch immer den Flow-State bringt https://en.wikipedia.org/wiki/Flow_(psychology) ... ob das nun auf Häkeln, Gitarre Spielen, oder Parkour hinausläuft, kann man ohne deine Neigungen zu kennen schwer sagen.

Interessanterweise ist gerade NRW da eher gespalten? Auch wenn die Karte da nicht so leicht zu lesen ist, scheint es mir, das der Artikel da, wo ich herkomme (östliches Ruhrgebiet), eher unüblich ist ... und das deckt sich auch mit meiner Erfahrung ... kann mich jedenfalls nicht entsinnen, das das da ein eine prominente Eigenschaft ist ...

Hmm not sure whether my cutter directly accepts SVG, I have to check ... in fact I'm using Inkscape to assemble everything and then just use the application to generate gcode ... not sure whether I can skip that step because the SVG doesn't contain any info regarding cutting speed, laser power etc ...

Oh I've never heard about that one ...

The problem with Davinci I encountered was that very common encodings like x264 or x265 don't work with the community edition and I can't justify getting the pro version from an economic standpoint ...

Supposedly a solution for Blender exists but I tried to make it work and failed :( https://www.cadsketcher.com/

If you don't mind using text-based interaction you could give OpenSCAD a try ... it's like TinkerCAD (solids and holes) but with code ...

I might be biased here because I'm a programmer by trade but I didn't find it too hard ... also mostly need boxy shapes ... but still, I think it's neat ...

My personal top 3:

Video Editing - Kdenlive isn't bad in and by itself but it seems really slow to work with, and getting any kind of smooth preview seems impossible even with proxy clips ... the other day I bought a GoPro 3D camera, and I can cut, preview, rotate, reframe and encode with their Android app on my potato phone from 2021, and it feels snappy (I was surprised, really). Yet on my i7 laptop with Kdenlive, much simpler tasks feel much more sluggish on average ...

CAD - I use OpenSCAD for 3D modeling and I love it, but sometimes a GUI-Based CAD program would be nice. I'm sure FreeCAD is powerful but the UI/UX aspect makes it hard to unlock that power. I'm a bit conflicted about it because I really don't want to play down the efforts of the FreeCAD dev team, and it seems like everyone and their mothers talk badly about their UI/UX. But on the other hand I tried a couple times and got really frustrated, and I'm usually not one to shy away from steeper learning curves. Supposedly you can do CAD in Blender but I never really figured that out.

Laser cutting - While most slicers for 3D printers work on Linux, Lasercutting seems a different story. You can still use older versions of Lightburn but it's not FLOSS and it seems strange to pay for a license if the support for your OS has been discontinued 2 versions ago (or one, not sure right now). I want to give Rayforge (https://rayforge.org/) a try soon but until then it's LaserGRBL or the program that came with my laser cutter on a virtual machine.

Honorable mention: A linux phone would be nice.

Ohje, erinnere mich noch an die Gentoo Stage1 Installation um 2009 oder 2010 ... nach 'nem Jahr oder so war die Overlay-Konfiguration in Portage so kaputt das es wesentlich schneller war, Ubuntu drüberzuinstallieren 😅 ... glaube das habe ich insg. 2x gemacht ... wobei, jetzt wo die Prozessoren schneller sind und das Kompilieren schneller geht, vielleicht wäre es mal wieder 'nen Versuch wert ...

I doesn't "need" to be imported, the question is just, where do we see the future of federated (non-)platforms ? Do we want them to be "small and cozy" with a small and fairly narrow selection of content or do we want a non-corporate alternative that can compete in richness and variety of interesting content of all niches?

A lot of folks only seem to see the crappy part of youtube and other platforms, and don't see the richness of content that exists ther. There's still so much interesting stuff to be found. I don't think there has ever been a bigger archive of, say, documentation about arts, crafts, history, food, than YT, even it its current enshittified form. If that's an ocean of content, the Fediverse isn't even a major river (at least that's my impression).

If you don't mind that, great. But I do, I'd love a non-corporate version to exist that can compete in terms of richness of content.

And monetary incentive is part of the puzzle, as it incentivizes people to spend time on it, which in terms generates a bigger audience, which in turn has a higher potential to support a wider range of content niches. Plain and simple.

I don't agree, really ... that'd limit the Fediverse to hobbyists.

It's completely legitimate to look for income & exposure as a creator, whether you're making music, visual art, or document your process making physical objects. Corporate platforms, as crappy as they might be, provide a path to that, and in many ways created viable path for creators to do what they like full-time. Not saying that it's perfect or easy. But the Fediverse is currently no alternative at all ...

Currently, restricting yourself to the Fediverse as an artist unfortunately means that you're taking quite a hit in terms of exposure you can get. As long as that's the case, and people even defend it, then we really can't complain that the Fediverse isn't attractive for a larger amount of people, and centralized platforms will always have the bigger draw.

I try to avoid corporate platforms as much as I can, but as a consumer I often feel starved of content. I haven't found any interesting woodworking channels on PeerTube, or guitar repair channels, or whatever else I enjoy watching to wind down.

And as a creator, well ... it's not my source of income, but I sure would like it to be. And if I ever decide to make that step, I'm pretty sure that I's have to make amends to my "no corporate platforms" approach. The Fediverse doesn't feed you.

Klar, da ist's noch beengter ... da wäre Gepäck einchecken an sich gar nicht so verkehrt, gerade für Menschen mit eingeschränkter Körperkraft ... die letzten Male, die meine Mutter mit der Bahn verreist ist (normaler Tages-Zug), hat sie das Gepäck meistens aufgegeben.

Hab bisher nur einmal eine Nachtzugreise unternommen, und fand' das zwar spannend aber nicht unbedingt alltagstauglich.

Das Mini-Kabinen-Konzept klingt da echt vielversprechender.

Wichtig fänd' ich auch gutes Gepäck-handling, z.B. mit 'nem bewachten Gepäckabteil ... den dicken Koffer in der engen 2er-Kabine zwei Etagen in's Gepäckfach zu hieven, war schon ein ganz schöner Akt ...

 

A while ago joined Pixelfed, and some things really confuse me ...

1.) Licenses ... on my older posts, the Image shows a content license (like, CC BY-NC-SA), but not on newer ones ... there doesn't seem to be a way to specify a license, or is there?

2.) Followers ... some friends joined on other instances, and we followed each other ... when I click their profile from MY instance, then I see only myself (seems like they don't have any other followers on that instance).

If I visit their profile on THEIR instance, I can see they have more followers, but I can't see the details without logging in (and the account from my instance doesn't work).

Is that by design?

I can't even see their profile picture from my instance ... my posts seem to show up in their feed though ...

3.) I'm using the official app, but I can only see my most recent posts ... I made a few posts about a year ago and they don't show up ...

Can someone enlighten me here?

 

Hi,

I recently bought a few pre-made amplifier modules for an 8-channel amplifier project (for a sound installation).

The amp is based on the TDA7294 chip and is rated 85W nominal. Now I'm looking for a power supply, but I'm a bit lost (this isn't really my strongest field, to put it mildly).

Do I just need to add up the output power, 8*85W = 680W, or could I get away with using something smaller, like a 300W or 300VA?

Also, the seller said that you need to use CV power supplies, CC won't work and kill the circuit. Does that mean a switching supply can't be used?

It looks like the module has a rectifier and smoothing caps integrated, so I could potentially just use a transformer, right?

Best, N
