addressing misconceptions about the recent TunnelVision vulnerability

I've been seeing a lot of confusion around the TunnelVision vulnerability. While I'm no expert, I've done a fair share of research and I'll edit this post with corrections if needed. The goal of this post is to answer the question: does this affect me?...

Thank you for summarizing it up

I've been using network namespaces in Linux where each one also use a different user; this way you can have multiple profiles of apps separated not only by permissions but also by the VPN connection that is the only route out

So you can have a connection that will supply your favorite iso sharer, a VPN connection to work, all unaware of each ot

I still haven't figured how to make GUI media applications work on them though

Sure, someone helped me setting up a script to share the wl socket between namespaces so I can run GUI programs in isolated namespaces, and if you look at this post you can check the namespaced-openvpn; also check vole's answer if you want to run GUI programs

Used to be messing with kernel arguments and installing/tweaking boot parameters. That was until Grub broke, I learned systemd-boot and chrooting into the system via live USB

Now if I break anything it's just a matter of "sigh, let me get the USB and type a few commands"

That'd be over 1TB with zram on

Depends on config, ArchWiki recommends optmizing some sysctl values to take advantage of it

it generally starts kicking in after >60% RAM usage even with this config

Considering it's almost always 30°C+ 60%+ RH at least half of the year where I live, yes

Refrigerating them increases their shelf life significantly in these conditions

It's probably less effective in other cooler and drier climates

Happened once around two years ago, s botched update from mainstream or something like that. Made me learn systemd boot which is simple and never EVER use grub again

AMD is the gold standard for general user PCs in the last 5+ years. Intel simply cannot compete at the same energy expenditure/performance. At the same/close price/performance, Intel either burn a small thermonuclear power plant to deliver comparable performance, or simply is worse compared to similar Ryzens

Ryzens are like aliens compared to what AMD used to be before them

So I'd go with them

As for the GPU, if you want to use Linux forget Nvidia

I finally switched to AMD after 3 years in Linux, and man I didn't even know I was suffering until I booted with AMD and didn't have to take care of several env variables and separate modules for hw acc

It just works

My most paranoid config is disabling Ipv4

That's it. If someone wants to attack me, they will need to adopt IPv6!

Most things would be solved if mainteners EVER updated their app's electron version or stopped doing custom things with it and just let electron read $XDG_CONFIG_HOME/electron-flags.conf

It actually runs and feels smoother for me in a 144hz display and 2016 NVDIA card. Of course it still has its glitches and strange things happening from time to time, while with Xorg it "just works". I'd say it's still in alpha stage for Nvidia users, which require some tweaking and extra env variables to properly work; and in beta stage for everyone else

Heya could you share how you do this trick to screen share ?
Would it work on MS Teams?

I managed to use Waypipe to open a GUI programa unde another user in the same Wayland display (actually someone else did a script for it, it's in my profile history), so I guess it is possible to forward it with Waypipe remotely

shadowintheday2 ,

I switched to systemd boot when that happened, and it's been so smooth ever since

shadowintheday2 ,

It's not exempt from happening; however, it rarely ever updates and has less complexity/functionality than grub, which makes it less prone to error happening (be it from the developers, or from the user like me trying to theme it :))
