"If flywheels seem like an exotic energy storage solution, that’s largely because they have generally been relegated to niche applications. A spokesperson for Qnetic told pv magazine USA that grid-connected flywheel pioneer Beacon Power deployed 400 of its 100 kW (25 kWh) units at two utility sites in New York and Pennsylvania between 2011 and 2014 to provide fast-responding frequency regulation. Each location had 200 units with a nameplate capacity of 20 MW (5 MWh), and both are still providing frequency regulation service and generating revenue."

I would assume that flywheels are exotic because their niche (short- to mid-term storage, quick reaction times) wasn't much needed so far in a grid dominated by non-renewables. This will probably change in the future.

But for the same reason I don't get all that talk about competing with lithium-ion batteries. Flywheels don't really fit the same category as batteries. And lithium-ion batteries in particular are not well suited for grid-level storage anyway. Their benefit at the moment is basically just availability because that's the type of battery that was produced and optimised at scale for –at least– the last decade.

    Du versteht das falsch herum. Der Verbrennerverkauf und die damit verbundene weitere Vernachlässigung von Elektroautos wird DER Grund sein, warum sie nicht wirtschaftlich erfolgreich sind. Denn wenn man nicht in den nötigen Stückzahlen baut und keine eigene Versorgungskette aufbaut, sondern nur die Teile bei der Konkurrenz kauft, kann man halt langfristig zumachen. Oder –wie es unsere Unternehmen versuchen werden– laut heulen, damit stattdessen der Staat einen finanziert, um die mutwillig gefährdeten Arbeitsplätze zu erhalten.

    All the Archlinux based ones, too. (Although I don't accept the buggy mess that is Manjaro's Pamac as an actual tool.)

    The only way to get a distro with no graphical updater by default nowadays is using one that does not come with a graphical desktop by default (so archlinux and some server installations...).

    As the "graphical update tool" is just a basic wrapper for the normal updater, I would be very surprised if any distro coming with a desktop environment by default has none...

    So the answer would be "every single one but Archlinux (nothing by default but the base system) and server installations"

    (PS: My "graphical" updater on Archlinux is a handful of very small scripts that a) runs checkupdate and flatpak remote-ls --updates from time to time writing the result into a temp file, b) displays an indicator if that file isn't empty, c) prints out the file as a notification on clicking that indicator and d) runs pacman -Syu && paru -Syu -a && flatpak update && pacdiff in a terminal window when I right click the notification.)

    (PPS: Small correction... Manjaro doesn't have graphical updater but a buggy abomination prone to fucking the AUR instead.)

    Die wahnhafte neoliberale Zerstörung von Sozialstaat und Zivilgesellschaft, um möglichst alles zu privatisieren, damit auf Kosten der Mehrheit eine Hand voll überreicher Menschen noch viel reicher werden kann, hat keine Lösungen für die Zerstörung von Sozialstaat und Zivilgesellschaft bei gleichzeitiger ständiger Enshittification durch Privatunternehmen und Verarmung fast aller und den daraus resultierenden gesellschaftlichen Widerstand und Protest gefunden?

    Wie kann das nur sein???

    (Oder wie es hierzulande gerne als "Lösung" erschallt: "Wir müssen die 'Reformen' nur radikaler durchdrücken, dann versehen die idiotischen Wähler es sicher auch!")

    Tagtäglich zum eignen Vorteil Entscheidungen gegen Deutschland treffen, während die Wählerherde so verdummt wurde, das sie immer noch ständig von Dummheit oder Inkompetenz redet, statt von Bosheit und Korruption, ist durchaus beeindruckend.

    zeigt, dass man kombinierbare Workshops trennen sollte um die Zielscheibe auf dem Rücken zu minimieren

    Das genaue Gegenteil ist der Fall: Du konzentrierst nicht die Zielscheibe auf dem Rücken einiger weniger, damit du deine Ruhe hast, sondern verteilst sie auf dem so vielen Rücken, dass klar ist, wer die Mehrheit ist, und dass es keine alleingelassenen einfachen Ziele gibt.

    Thank you for –just accidently of course– getting rid of all the "...with the screaming they constantly use to divert from their corruption"-context.

    What an interesting coincidence that people parroting populist talking points always use the exact same populist tactics.

    Jahrelanges, eklatantes journalistisches Versagen, um die immer gleichen rechten Narrative zu verbreiten und Spaltung und Verrohung in der Gesellschaft voran zu treiben, und sich dann wundern, dass man in einer gespaltenen, verrohten Gesellschaft, in der die keifenden Populisten den Ton angeben, für von deren Linie abweichende eher Meinungen bedroht wird...

    Die Leoparden fressen Gesichter eben auch, wenn man jahrelang fest die Augen zugekniffen und so getan hat, als hätte man nichts gesehen.

    As this will -thanks to me being quite clueless- be a very open question I will start with the setup:

    One nginx server on an old Raspi getting ports 80 and 443 routed from the access point and serving several pages as well as some reverse proxies for other sevices.

    So a (very simplified) nginx server-block that looks like this:

    # serve stuff internally (without a hostname) via http
    server {
    	listen 80 default_server;
    	http2 on;
    	server_name _; 
    	location / {
    		proxy_pass http://localhost:5555/;
                    \# that's where all actual stuff is located
    	}
    }
    # reroute http traffic with hostname to https
    server {
    	listen 80;
    	http2 on;
    	server_name server_a.bla;
    	location / {
    		return 301 https://$host$request_uri;
    	}
    }
    server {
    	listen 443 ssl default_server;
    	http2 on;
    	server_name server_a.bla;
       	ssl_certificate     A_fullchain.pem;
        	ssl_certificate_key A_privkey.pem;
    	location / {
    		proxy_pass http://localhost:5555/;
    	}
    }
    #actual content here...
    server {
    	listen 5555;
    	http2 on;
        	root /srv/http;
    	location / {
            	index index.html;
       	} 
        	location = /page1 {
    		return 301 page1.html;
    	}
        	location = /page2 {
    		return 301 page2.html;
    	}
            #reverse proxy for an example webdav server 
    	location /dav/ {
    		proxy_pass        http://localhost:6666/;
    	}
    }
    

    Which works well.

    And intuitively it looked like putting Anubis into the chain should be simple. Just point the proxy_pass (and the required headers) in the "port 443"-section to Anubis and set it to pass along to localhost:5555 again.

    Which really worked just as expected... but only for server_a.bla, server_a.bla/page1 or server_a.bla/page2.

    server_a.bla/dav just hangs and hangs, to then time out, seemingly trying to open server_a.bla:6666/dav.

    So long story short...

    How does proxy_pass actually work that the first setup works, yet the second breaks? How does a call for localhost:6666 (already behind earlier proxy passes in both cases) somehow end up querying the hostname instead?

    And what do I need to configure -or what information/header do I need to pass on- to keep the internal communication intact?
