Ubuntu needs feedback on some possible major WiFi changes
13 Aug 2020 at 10:35 am UTC
What I do miss though is WPS-push-button.
WPS is probably the only technique that securely can give any client a random 256 bit password.
<RANT>Okay, now we get tons of people that don't know WPS saying how insecure it is. It is not. There is only one variant of WPS that's insecure and that's the let's print a code on the device. Which goes directly against security. And most access points do not give a client a random 256 bit password, they give a shared password.
So WPS is absolutely more secure than a PSK when combined with openwrt.</RANT>

it works it seems..

Quoting: Pikolowpa_supplicant works with EAP, at least for eduroam(the worldwide federated university WiFi network). At least when used through network manager, unless Ubuntu has something hardwired to take care of that edge caseEAP is not an edge case. EAP is important for WPS too. So any wireless network controller that does not support authentication through EAP should not be used.

My experiences of Valve's VR on Linux

My laptop is good enough according to the specs on the site. I wonder...
(RX580 eGPU and a i7-3610QM clocked at about 60% max in a Thinkpad T430, I game in 4K on this rig, while my steammachine with nvidia (zotac SN970) barely copes with 1080p, thanks Valve for fixing these AMD drivers!).
Because the investment is quite steep for something that might even need an extra 2000 euro investment for a pc that I don't have a place for. The worst part of it all: I have 3 generations of gear-vr, and they all fog up after 5 minutes. (gear vr looks much better than oculus rift dk2 BTW).
How would the index fare on my head? :-(.

I do mind the nvidia: nouveau is crap. The proprietary drivers are crap and do not work together with PRIME. Also the proprietary drivers do not accept output from the intel gpu being routed to the output to the nvidia, you need active bitblitting of the intel workspace to the nvidia framebuffer. That's because it's proprietary. Not because it is not possible. So from a working displayport on intel only it went to a defunct displayport when I got the replacement laptop. I hope in the future nouveau will reach a state that's comparable to the current state of r600.
To be clear: I think just enabling optimus in the bios just starts eating away 15W. It's not doing anything. If I could, I would desolder the GPU. The intel driver is so much better than the proprietary nvidia driver.
The only time I willingly bought nvidia again after my first encounters with them, was for the steam machine. I wanted to support the idea. But the current state is crap.
For pc's I will only buy intel or amd as gpu. I don't have the time to support crap drivers.
</big rant>
One thing though: the express card will give you a PCIe2 1x bus. So that's 1/32th of the full speed of PCIe (500MB/s instead of 15.6GB/s). I was able to display 4k@30Hz that last version of tombraider to someone as a demo without to much stutter. Unplayable of course, it's a tad too heavy.
GTA IV and GTA V works well.
AMD GPU drivers have a kind of pci statistics, and it shows that the bus during playing usually is not saturated.
The usual way how PCIe3x16 is that it works in PCIe2 mode, and only when needed it switches to PCIe3 mode.
Although I have no system anymore to test it. You can find all this information in the /sys filesystem. I don't think nvidia has pcie statistics though. So except of what the pcie bridge tells you (lanes and speed), you know nothing. Only certain intel server bridges have traffic counters.

Quoting: scratchiCool, thanks, nice set up! I looked into this and found this one on Amazon that looks pretty decent:That's exactly what I have. I added the perspex casing so the card would not be lying around. My gdc beast was half the price or so, and with casing the price what you quote using aliexpress, but I think through amazone you get some guarantees.

Quoting: scratchiI don't mind the Nvidia GPU, it's just old Fermi doesn't get new drivers anymore, stuck on legacy 390 drivers (no vulkan support). It's just old, that's all.<big rant>
Anyway, the T530 is so big and heavy I'm not going to be moving it anywhere, so adding an external GPU to it seems sensible, if not just for the experiment factor alone :) Thanks for the idea and info!

It's a bit messy since I use a lot of tissues (for my nose!), and I am reworking some led lighting.
I had 2 weeks to make that DDJ-SX3 work on linux: make it work, or send it back under consumer law. That screen is a 4k 40" screen.
I've divided my laptop in 2 seats: the DJ console and my (new) desktop. My other desktop is an exynos 5422. I don't really like PC's, because there is a lot of things wrong in the design due to legacy. And an arm is cheaper and doesn't need a fan. And mmc drivers on PC's are always crap, especially on a GPD WIN(2). But not on this T430.
The biggest crap is the Nvidia, the same as in your system. I had to return my pure intel T430 for repairs, and I got back a T430 with a better screen, but also with that nvidia. Really... The intel has better support, and still gets TLC. The best thing to do with the Nvidia is to turn it off in the bios. When I turn it on, but actually of using prime, it still uses more power, and the fans run higher than normal.
Also the replacement got a different CPU, a high end i7 with a tdp of 45W, but by limiting the CPU to 60% it was fast and usable.

It feels like the best PC linux system I've ever had at home, except for the supermicro's.Dude, this sounds fun! Which express card do you have? Can you send a pic of what this looks like?
Everything works. Except of course that nvidia crap.
Added an eGPU using express card. RX580. The system feels a lot faster than my zotac sn970.
I have a T530 with Nvidia NVS5400. It works fine in FreeBSD, but it's not a whole lot better performance than Intel IGP. Just upgraded ram to 16GB and an RX580 would make really make it complete :)

Back around 2000-2005 we had several companies (Like Stichting Internet Reclame) in the Netherlands that denied the existence of people using Linux and firefox. None of their metrics showed the existence of these visitors.
They failed to mention that the way they measured was by installing snooping software on the windows systems of the volunteers. The bogus results of Stichting Internet Reclame and other companies destroyed the self hosting of advertisement servers and software, because they showed different results. This eventually has lead in the Netherlands to the intrusive ad networks we see today. Mass spread of virusses thanks to these
As a matter of fact: I am battling one right now, as a client even, because just serving a pixel to give feedback the ad has worked, actually redirects them to parties I've never heart of.
The original was a javascript that they called pixel. It basically downloads other javascripts from unknown sites, and runs that. On a simple GDPR compliant page, the page went to 60% marketing network and gross violation of GDPR, and to have an add run on their network is very expensive.
How did I get here ranting like that?
Oh yeah: I don't trust stats like that.
I never did. But at least you can twist the stats of NetmarketShare to something that supports what I want to see:

Meeh, 5 minutes in and it crashes (walking into the computer room that in the original is only accessible after the incident). So I tried using the proton version, and that doesn't start at all.

Would be nice if they can apply some ip matching to match the original Steam account with the Smurf Steam account, and address warnings there too. But then again, that might be a privacy issue.
Maybe they should ask the right to process your IP against fraud cases like this.

Sometimes I even only need a secondary ip stack... ip netns to the rescue...
Lxc is just a wrapper on the set of different nameserver creations and migrate systemcalls. You can do it using bash :-). Lxc is very nice though.
I don't know flatpak, but from what I've seen, they are just squasfs like files mounted. No security or whatever unless the flatpak itself does that. I doubt that's what they are doing.

Quoting: EagleDeltaA container to me is something that encapsulates itself into it's own namespace.I don't think this is using what many of us would consider "true" containers in that they aren't (AFAIK) based on LXC or ContainerD, but are Flatpak-based containers. I could be wrong though
