Hab' die ersten 30 Jahre in der gleichen Stadt, am Rand des Ruhrgebiets, gewohnt, bin nur 1x umgezogen. Kannte mich gut aus und hab an sich das ganze Ruhrgebiet von Bochum bis Duisburg in nächtlichen Streifzügen erkundet, und mich immer wieder gefreut, nach Hause zu kommen. Dachte eigentlich immer, das sei wichtig für meine Ich-Konstruktion.

Dann bin ich umgezogen, erst in ein anderes Bundesland, dann in eine große, laute Stadt in der ich am Anfang keine der lokalen Sprachen sprach.

Da hab ich dann gemerkt das man zwar nicht verleugnen kann, wo man herkommt (kulturell, etc), das eigentlich aber auch gar nicht so wichtig ist. Hier mischt sich alles, auf 'ner Party mit 20 Leuten sind 11 Herkunftsländer vertreten, und das ist wunderbar.

Die unmittelbare Umgebung (so 200m Umkreis), in der ich aufgewachsen bin, ist mir immer noch lieb und teuer, und da meine Eltern gemietet haben, werd' ich da irgendwann keinen Zugang mehr zu haben, was mich ein bisschen traurig stimmt. Aber trotzdem hab ich kein "Heimweh".

Zu der lokalen autochtonen Kultur hab ich hier, am neuen Ort, nur bedingt Zugang. Mag sprachliche Gründe haben, oder auch das die Leute hier recht "stolz" sind und man schon viel Arbeit verrichten muss, um da rein zu kommen. Ist aber auch nicht so wichtig, bin eh' ein bisschen Eigenbrödler, und hab auch mit einigen Leuten, mit denen ich früher 30 Jahre Tür an Tür gewohnt hab, nur 20 Worte im Leben gesprochen.

Auch in Deutschland wär nicht der Typ für 'nen lokalen Traditionsverein. Was es in der Richtung in der "Heimat" gab, hat mich auch nie so recht interessiert, und das was einem irgendwo "nahe" vorkam, hat sich mit etwas Abstand auch eher als Romantisierung herausgestellt (Bergbau war echt nie so toll, und sich mit "Glückauf" zu begrüssen auch 'n bisschen albern wenn mans so recht bedenkt).

Da wo ich jetzt wohne gibt's dafür 'ne aktive Szene für das schräge Zeug das ich so mache (künstlerisch), an derem Aufbau und erhalt ich aktiv beteiligt bin. Insofern, manchmal muss man sich die Heimat einfach schaffen.

Ok, sorry, ist etwas ausgeartet, ist aber tatsächlich was, was mich manchmal beschäftigt.

Hmm spannend. Bin im letzten Jahr wenig gefahren, weil ich zum einen keinen Pendelweg mehr habe (arbeite von zuhause) und zum anderen Radeln in der Großstadt immer stressiger fand, und für Sportradeln keine Zeit mehr fand.

Die letzten Wochen allerdings habe ich wieder mit kurzen Strecken angefangen, die allerdings 400+ Höhenmeter haben (für mich der einzige Weg, schnell und ohne Abgase aus der Stadt zu kommen). Muss sagen, sich den Berg raufzupushen, und dann die Abfahrt zu genießen, hat auf jeden Fall 'nen positiven Effekt auf die Psyche, und auch die Stadtstrecken kommen mir auf einmal weniger stressig vor.

Das mit dem Fahrrad ist sehr ortsabhängig ... wenn's halbwegs flach ist gibt's nichts tolleres als die starre Achse ... aber wenn fast alle Wege die man fährt 50% bergauf und 50% bergab sind, und man IMMER einen nicht ganz passenden Gang hat, ist's doch eher nervig ... da hab ich Freilauf und Schaltung doch schnell vermisst ...

I have to admit, when it comes to new developments in the Linux world, I tend to live under a rock ... never switched to Wayland, not because I have any ideological reservations, but because my favorite WM (a minimalist WM developed by a friend of mine) is available only for Xorg.

I had heard about NixOS before, but until I stumbled upon this thread, I didn't have a good understanding about what an atomic distro is. Now that I have a bit of an understanding, I guess I can only repeat what others said before, it seems to be solving a problem that I don't have. I've been using rolling release distros for a very long time (at first Gentoo, like, 15 or more years ago, but Arch (btw) for over a decade now, with occasional, typically short stints in Debian-based distros), and the amount of problems caused by updates has been negligible for the last decade (Gentoo overlays 15 years ago could be a pain, for sure).

It does sometimes bother me that my OS config seems to so ... static these days, but then again I have so many things going on in life on that I don't feel a huge need to prioritize changing an OS that feels blazingly fast to use, stable, minimalist, and basically checks all the boxes. It just became my high-productivity comfort zone.

Hmm my first linux distro was Suse 5.x that came on 5 CDs (i think it was 1998) ... can't say I used it much, I had weird German ISDN Internet at the time and the PPPoverWhatever (forgot the exact name) just didn't wanna work. Making music wasn't really feasible at the time. It mostly lay dormant. I slowly climbed the learning curve and switched to Linux full-time in the mid-2000s, when a lot more things were possible ...

My first ever smartphone (in 2015) was a BQ Aquaris 4.5 Ubuntu Edition that came with Ubuntu Phone pre-installed ... a lightweight, 4.5" smartphone ... there wasn't much of an app ecosystem at the time but I didn't miss it because up to that date I used a dumb phone, and the smartphone allowed me to do eMail and use a browser, which was enough for me.

At some point I accidentially dropped it on a hard floor and it broke, and I was quite unhappy that the company didn't continue that line :(

I guess it depends a lot on what you think of as "an alternative". I'm really happy using FOSS because I generally try to find a different angle on things, and it allows me to do that.

Luckily I'm not dependent on using common office software, the few spreadsheet tasks that I need can be done with online tools, either open or proprietary. For documents I usually use markdown and pandoc. For music making, I use my own software or Ardour for mastering, etc. For modeling and 3D printing I started using OpenSCAD.

There's also many things that proprietary software just can't do. Like, my day-to-day workflow is based on a minimalist approach to computing, with the most common operations being very easy to perform (browser, editor, terminal) ... MacOS is always hailed for their great UI but honestly, it seems slow and clunky to me even though I used it daily for a long time ...

Second this, I've tried TinkerCAD before and the whole Idea of CSG started to make sense, and then I found that OpenSCAD does something very similar, just with code ... I find it very satisfying ... I guess if you're making highly asymmetrical, organic shapes, you might have some puzzles to solve ... but I'm mostly making loudspeakers, so basically boxed with holes, and it's not a huge problem.

Hmm I think the issue is that Ardour is more focused on recording than electronic music production ... There's more intuitive DAWs out there but I suppose in terms of what it can do it doesn't have to stand back ... compared to ProTools I'd say it's still quite intuitive (not a high bar for sure).

hmm I might be biased because I'm a programmer by trade, and even make music with code, so describing things as code is pretty natural to me ... but I once I got the hang of it I found it easier than TinkerCAD in some sense, because there I would always get lost in the stack of objects ... and FreeCAD ... well, I couldn't even get a basic box designed ... 😅

Meh ... I wish there was a middle ground. Non-corporate, yet effective. Unfortunately, the Fediverse is only the first.

Discovery algorithms can be great, if applied with care. And I really think ActivityPub is not very effective at showing interesting stuff, while from a user perspective it's super intransparent. Personally I'd prefer a centralized user experience to the Fediverse fragmentation any day ... I guess I'm really only here because I'm fed up with corporate bullshit.

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
