Nvidia Fuck You! (Linus Torvalds) My thoughts exactly

Reply in thread

I got myself an expensive-ish rx 480 because nvidia said they will support vulkan on it. They never implemented vulkan for fermi. Never again will i buy from greedy liars.

Linus is talking about a different thing entirely. And while their drivers were always great, there is much more to the story then just how well they render 3d.

Slackware turns 30 today

Reply in thread

On slackware-current. Latest kde, mesa, fairly new lts kernel. All vanilla software (with security patches). Xfce, and more. No official gnome. Everything works, simple system. No official package dependency resolution, install a lot of packages recommended (they in groups). Good for me.

Edit: oh, and very stable

Slackware turns 30 today

Reply in thread

Current has mesa 23.1.3 and kernel 6.1.

Been a while since i built a kernel. Way i did it was (as root):

  • download from kernel.org into /usr/src/ (wget https://cdn.kernel.org/pub/linux/kernel/v6.x/linux-6.4.3.tar.xz for example)
  • cd /usr/src/ and tar xvf the-downloaded-tarball
  • rm linux - it's a link to kernel source, so that programs can compile against the kernel (rarely necessary)
  • ln -s linux-downloaded-one linux - makes new link to downloaded kernel
  • cp linux-installed-kernel/.config linux/ - copy the old config to the new
  • cd linux then make oldconfig - a lot of questions about all the new options, that should include the new arc drivers if they are not included into old ones
  • make menuconfig or make nconfig - are TUI-s to configure the kernel. nconfig has a search (F8)
  • make bzImage modules - to compile the kernel and modules (basically shared libs)
  • make modules_install - copies modules to /lib/modules/version (important as most drivers are modules)
  • cp arch/x86_64/boot/bzImage /boot/vmlinuz-version - copy the kernel core to /boot
  • edit /etc/lilo.conf - if you use grub then idk
  • go to bottom, copy the whole block including image = ... , keep the original to have a bootable kernel
  • change /boot/vmlinuz to whatever i called mine
  • run lilo
  • reboot
  • reorder lilo boot order if i forgot to before, and lilo then reboot again to confirm

Not the official slackware way, but.. actually slack is the slackware way. Have borked my system plenty of times and had to dig up the install cd/usb to fix it.

There is documentation on slackbook http://www.slackbook.org/html/system-configuration-kernel.html but it's a bit outdated. You can always ask questions on the official forum https://www.linuxquestions.org/questions/slackware-14/

Why exactly is deferred rendering faster?

Reply in thread

Usually renderers do a z pre-pass to eliminate overdraw. Real reason for deferred shading to be faster would be lights. In normal forward, every light has to be accumulated for every pixel. And this problem is solved today with clustered shading (aka forward+). Link to paper: https://www.cse.chalmers.se/~uffe/clustered_shading_preprint.pdf

In short, these days deferred shading is slower because of memory bandwidth.

New plasma-based noise cancelling tech may silence rooms, planes, and even cars

Reply in thread

It is impossible to "cancel" noise in a room, because physics. Maybe you could cancel out some waves in some parts of a room, but you would probably intruduce your own waves in other parts of the room.

My advice: get some foam/stone wool, plants, a couch, put a blanket on the wall and or ceeling. Absorb the waves. Active noise cancelation only really works in earphones.

why did you switch?

Dota (1, in warcraft 3) would have a hitch every once in a while, and i'd die if it was in a fight. Cause was swap writing to disk, that you can't turn off in winxp. I was already looking at linux, so i said f it. Bdw warcraft 3 runs well on linux if you add -opengl.

cable rule

Reply in thread

Gold plated is good, because gold is rather chemically inert. Oxydation of steel/aluminium will cause small contact points of high resistance, that cause heat and accelerate oxydation. Rarely a problem though, and very easy to hear. One problem you might get with cables is if a long signal cable is too thick and long it can act as a capacitor and filter out a bit off the high frequencies. All in all "audiofile" grade cables are bullshit at best.

There was a website sound-westhost or something where they wrote good about a lot of audio topics. I can dig it up if you are interested and can't find it yourself.
