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 ...

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.

OBS for streaming is amazing.

Ardour is a pretty amazing DAW that can compete with proprietary ones. There're also loads of FOSS plugins out there that don't have to hide behind the commercial ones. My favorites are the Calf Plugins and the Luftikus EQ for mastering. Helm and Yoshimi are great synths. Pure Data is lightweight and can compete with MaxMSP.

Krita has already been mentioned.

But, I think what strikes me most is that there's a lot of FLOSS software out there that just doesn't have direct proprietary counterpart. Small command-line tools like FFMPEG or ImageMagick. Linux as an customizable OS. Programming Languages to make music like SuperCollider. I never learned how to use proprietary CAD software but recently got into OpenSCAD to model some things and it's really fun once you get the hang of it. I don't do this professionally so there's no need for me to learn Fusion360.

Some have a bit of a learning curve but are all the more satisfying to use once you get into them. People are just too stuck in their "industry standard" (which really just means "the most common product that has been around the longest"), but if you're not bound to that, there's just a huge number of programs out there that allow you to do amazing things. That to me is the beauty of FLOSS.

An FreeCAD hab ich mich auch schon mehrfach aufgehängt ... selbst einfachste Dinge erscheinen da sehr kompliziert, und ich hatte bisher nie den großen Durchbruch ...

Wollte einen kleinen Lautsprecher 3D-drucken, und in der Zeit, die ich FreeCAD-Tutorials studiert hatte, hatte ich mit TinkerCAD schon zwei Iterationen des Prototyps in der Hand ... und sogar Spaß dabei ... klar ist TinkerCAD nicht vergleichbar mit professionellem CAD, aber ich wollte ja auch nur 'n Kiste mit Löchern drin machen ... dafür ist 'n volles CAD-Programm eh' overkill ...

Halbwegs intuitives CAD Ist tatsächlich noch 'ne große Lücke im FLOSS-Universum ...

Meine sind gestern Nachmittag in Katalonien angekommen, heute für 45€ per DHL Express verschickt, angeblich kommen sie Morgen, end-of-day, an ... hab' sie nach Rücksprache direkt ans Wahlamt meiner ehemaligen Gemeinde veschickt, statt an das Postfach.

Generalkonsulat hätte Dienstag rausgehen müssen, das hätte nicht mehr geklappt ... teuer, aber in der derzeitigen Lage war's mir das dann irgendwie wert, jede Stimme gegen die AfD zählt ...

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

 
 

Hi,

wollte eigentlich heute radeln, allerdings ist die Luft dort, wo ich wohne, so mies heute das ich lieber zuhaus' geblieben. AQI zw. 70 und 130, Sichtweite kaum 1km, hohe Feinstaubbelastung (insb. PM2.5).

Das wirft die Frage auf, was tun wenn man unbedingt radeln will oder muss? Hab's mal mit 'ner FFP2 Maske versucht, aber um ehrlich zu sein ist das, gerade bei Hitze und bergauf, nicht so angenehm.

Lieber zu Fuss gehen/ ÖPNV nutzen? Einfach nicht so viele Sorgen machen? Würd' mich interessieren wie andere das sehen, oder ob ich da nur etwas paranoid bin ...

Best, N

 

Hi,

habe neulich angefangen, wieder etwas mehr Rennrad zu fahren.

Nun wollte ich mal meine Strecken aufzeichnen.

Habe bisher ein paar Routen auf WikiLoc eingetragen. Zum Entdecken und Teilen von Trails find ich's super, finde es aber seltsam, das es jedes mal eine neue Strecke anlegt, selbst wenn man die gleiche Route fährt.

Daher, kennt jemand eine gute Free & Open-Source App, um seinen Fortschritt zu tracken? Navigation ist nicht so wichtig, geht mir eher um Kilometer-Tracking etc.

Früher hatte ich immer 'nen simplen Fahrradcomputer (Sigma oder so), aber irgendwie find ich's ganz erfrischend, die aktuelle Geschwindigkeit nicht immer vor Augen zu haben.
