trying Everspace with SteamVR on Linux
trying Everspace with SteamVR on Linux YouTube video by Christoph Haag

Everspace? That's one of the few games that have VR support natively on Linux. At least it had 7 years ago. www.youtube.com/watch?v=-_DO...

Now in Aachen where of course on the german side there is no mobile signal and they fixed the wifi portal. But I still wonder why it is so often broken.

Does anyone know why the @deutschebahn.com ICE train wifi login website almost never works? (bruxelles frankfurt again)

And I can confirm that the 3.7.1 release runs very nice and smooth with an RX 6900XT eGPU. Nice work.

There is a community made tool called Envision that helps compiling and running it if you are interested in a less manual setup. Also the environment variable STEAMVR_LH=1 on monado-service will make it use SteamVR's closed source lighthouse tracking, which is generally more usable.

Wero so far has been absolutely exclusive to android and ios apps.

I'm told there are some banks in the netherlands that do have a web interface for ideal and don't require an android/ios app. Whether they will actually keep this functionality when joining Wero is not officially answered afaik.

Im Vorfeld dieser Veranstaltung wurde hier auch ein Fall von Debanking aufgrund von US Sanktionen erwähnt. In diesem Kontext sollte man die Bankvertreter eigentlich schon fragen, wie jemand, der keine Google oder Apple Accounts haben kann, offiziell an die zwingend nötige Banking App kommen soll.

Habe nur das Transkript überflogen. schade, dass "Google Play", "Android", "iOS" wieder gar nicht angesprochen wird, aber dass man es "einfach in der App" aktivieren soll. Damit gefragt wird, wie man dann ohne Google oder Apple OS bezahlen soll, muss ich wohl doch selbst zu solchen Veranstaltungen.

SDL won't tell you about all the underlying OpenGL stuff, but all (?) the platform OpenGL APIs have ways to query the "current" gl context, window, etc., so if you query those right after initializing SDL, it's unlikely to not work.

E.g. gitlab.freedesktop.org/monado/demos...

Wie gut funktioniert Wero noch, wenn Trump Google sagt, mittels play store und Google Play Protect alle europäischen banking apps von Smartphones zu deinstallieren und die Play Integrity API alle Smartphones mit Google Play in EU als unsicher zu deklarieren? Apple hat vmtl auch ein Äquivalent dazu.

Banking App lässt kein Log-In mehr zu Seit heute bekomme ich bei meiner Banking-App beim Starten die Meldung, dass die App aus einem nicht vertrauenswürdigen Store installiert wurde und das Einlogge

Banking apps are supposedly like 50:50 whether they run without google play and can change this without warning or recourse, even if you use a gray method to get the app in the first place, eg forum.volla.online/viewtopic.ph...
Personally I never used one of those apps and don't plan to.

But are they concerned about the supposed alternatives being - officially - exclusively accessible from american app stores that - officially - require an account with them and are only accessible with smartphones that run proprietary software with full system access?

B-stock sales are so disappointing. Yea that laptop wasn't cheap when it was new. But it's a possibly pre-owned laptop with a 12 year (!!!) old CPU. And you want 282,99€ for it? Are stores *that* desperate to not sell any hardware for actually cheap no matter how old it is?

Not the AC in the room but some kind of resonance.

I can live with the wooshing of cars outside the window or heaters, but higher pitched noise like this will probably always keep driving me insane.

Definitely not booking in this hotel again.

Loud enough to wake and keep me up since 5 AM.
*sigh*
Pretty sure it's the AC.

Today the first ICE from Stuttgart to Frankfurt had 41 minutes delay and I missed the ICE connections. Had to wait 2 hours for the next ICE because can't take the Eurostar instead. The next ICE stranded in Aachen, again can't take the Eurostar instead.

Also can @deutschebahn.com *finally* make an agreement with @eurostarnews.bsky.social that travelers *can* use the other one without buying a new ticket if the ICE connection between Frankfurt and Bruxelles fails?
(Written from RE18 from Aachen to Liege where I will take an IC to Bruxelles)

I'm not against entertainment for kids of course. But why are we abandoning any quality standards for entertainment and are now training children to get addicted to wasting hours on slop that has nothing to say? Is this why mainstream movies are getting worse too?

On this train there's a young child getting her brain cooked by youtube kids the entire way from Frankfurt to Bruxelles. Older people have always complained about the habits of the young but I can't help but feel that this is different and that brainrot content is genuinely hazardous to our brains.

Can @deutschebahn.com maintenance maybe make sure that the ICE train onboard electronics don't produce obnoxiously loud noise for hours on end? It seems to be quite common in the door areas, less in the seating area, but trains are quite often full enough that people are there too.

The real error message will be in ~/.steam/steam/logs/vrserver.txt or ~/.steam/steam/logs/vrcompositor.txt btw

I forgot I can click the profile button. Turns out it's just GC. Every few seconds it takes several seconds of this CPU usage.

My guess is too that it will be just a mirror of a full offscreen plasma session. But I'm also curious how exactly they'll do it, a regular pipewire screenshare, or perhaps some custom thing. In particular, how they'll make the plasma session sync the refresh rate with the display.

My guess is that the unnamed client is not Valve, but who knows, maybe it is.

@unity.com finally time to get OpenXR Linux support working?

You can gain an incredible amount of expertise *just* doing that. Of course success is not guaranteed, but there's a surprising amount of opportunities out there. Valve is the biggest and most visible player in the game but you can find this low level work in a lot more places than you'd think.

The most important thing is to not give up. It's easy to finish one thing and then abandon the topic. Just keeping on tinkering with a thing is so important and that's why it's important to choose a niche you actually like tinkering in, because you want to keep at it for a couple of years

People are often afraid of low level complicated areas, but you don't have to be. Just use C a lot and get a solid understanding how memory management works. gstreamer, wayland, mesa drivers, vulkan, synchronization, linux kernel - sounds scary? Yes, but just don't care and start doing.
