Könnte man die als "Krieg" bezeichnen? Vielleicht nicht unbedingt ideologisch motiviert, aber das liest sich schon nach recht systematischer Gewaltanwendung ...

I think many people are imagining it wrong, though ... it's not like every house in Barcelona has a parking garage, especially in the old town, but also in newer dense neighborhoods. It's just my estimate based on observation but I would say apartment buildings WITH a parking garage are the exception rather than the norm. If they have a garage, you still have to pay extra for the spot usually.

As a resident you can apply for resident street parking, which gives you preferential parking in the parking zones associated with your neighborhood. That's not free, either, but you can park at a discount.

But typically renting an apartment doesn't come with any guarantee that you'll have guaranteed immediate access to parking close to your place ... heck, if you're living in the old town you might have trouble finding a place to put your bicycle ....

EDIT: the article only mentions selling, not renting, so, not sure how that compares really ...

I still view the Japanese model as ideal ...

Parking on the roadside (outside the official parking spots, which you have to pay for) will usually get you a ticket or towed ... free public roadside parking is mostly a thing of the past in most densely-populated places, really ...

Since when is a parking spot a right? At least where I have lived so far, no apartment ever came with a guarantee for a parking spot, either you had to pay for a resident permit in your respective zone, or find a public spot, with free public parking (thankfully) becoming a rare occurrence these days ... very few buildings I ever lived in had a garage ...

I think this is one of the key quotes:

“It used to make sense to require parking in homes to avoid public spaces being filled. But this generates traffic because it encourages people to drive. Young people are also less likely to own a car. They may either opt for car sharing or renting.”

There's practically no free public parking in Barcelona. It's either for-pay or you have a resident permit.

I hope this frees up space, not just for sustainable transportation but also for more affordable housing, something Barcelona really needs ...

Use case is putting accents on certain elements of the stage, specifically loudspeakers (in a multichannel setup with loudspeakers placed around the audience). So they don't have to be particularly bright.

That one took me a moment as well ... why is there a difference between 2/2 and 4/4, or 6/8 and 3/4 ...

It started to make sense once I saw it as an abstraction. It denotes a certain emphasis on certain notes that would look really awkward and hard to read if it was repetitively written out for every note (not that I can really read music anyway).

I have a much harder time with harmony theory ... like, I get that some successions have a "resolving" feel but other than that I never got why I shouldn't just jumble up pitches any way that sounds ok to me. Ultimately I decided that I'll spend my life composing music, deliberately ignoring harmony theory as material ...

Other things that elude me a mostly social nature ... like, some people are just amazing at striking up some or another deal or barter their way through life at a discount, simple because they connect well to people. I never got how they do that ... not sure whether it's something you can learn

 

I'm looking for ideas to create small, battery-powered RGBW LED lamps for stage lighting ... something like this:

https://www.thomann.de/intl/ape_labs_lightcan_v2_creme.htm

I don't need all the DMX part, or even remote control ... just 1 or 2 strong LEDs, with a switch to choose between a few color presets, and a rechargeable battery that lasts 5+ hours.

I can roughly imaging the parts I need but I wonder if anyone has a hint or experience with something like this ... which parts to use etc.

I mean ... it's mostly functional but in times when I'm in decent shape (which fluctuates) in a way I like the look of a well-fitted jersey 🫣 😅 ... bibs and helmets always look kinda awkward though ...

[–] megrania@discuss.tchncs.de 2 points 2 months ago

They don't have to though ... mine looks moderately fancy but is really just a collection of used or discounted parts I scraped together over the last 20 years ... I have two jerseys, both bought when they were on sale, one is probably 15 years old ...

New shorts every once in a while because they wear out, the cheap ones work fine for me ...

So I still look like a MAMIL but in reality it's a fairly low-budget hobby ...

I summer 2026, at least in Europe, a lot of people try to stay away from heat sources as much as they can though 🥵

Unless you live in a densely populated area and the trains are packed to the max during commute hours ... not too uncommon having to stand, unfortunately :(

 

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
