The first big problem: PID 1

On unix systems, PID 1 is special. Orphaned processes (including a special case: daemons which orphan themselves) get reparented to PID 1. There are also some special signal semantics with respect to PID 1, and perhaps most importantly, if PID 1 crashes or exits, the whole system goes down (kernel panic).

Among the reasons systemd wants/needs to run as PID 1 is getting parenthood of badly-behaved daemons that orphan themselves, preventing their immediate parent from knowing their PID to signal or wait on them.

Unfortunately, it also gets the other properties, including bringing down the whole system when it crashes. This matters because systemd is complex. A lot more complex than traditional init systems. When I say complex, I don't mean in a lines-of-code sense. I mean in terms of the possible inputs and code paths that may be activated at runtime. While legacy init systems basically deal with no inputs except SIGCHLD from orphaned processes exiting and manual runlevel changes performed by the administrator, systemd deals with all sorts of inputs, including device insertion and removal, changes to mount points and watched points in the filesystem, and even a public DBus-based API. These in turn entail resource allocation, file parsing, message parsing, string handling, and so on. This brings us to:

The second big problem: Attack Surface

On a hardened system without systemd, you have at most one root-privileged process with any exposed surface: sshd. Everything else is either running as unprivileged users or does not have any channel for providing it input except local input from root. Using systemd then more than doubles the attack surface.

This increased and unreasonable risk is not inherent to systemd's goal of fixing legacy init. However it is inherent to the systemd design philosophy of putting everything into the init process.

RED HAT PAYING DEBIAN TO FORCE SYSTEMD

Systemd is not an init system!!
If someone characterizes systemd as an “init system,” you may safely assume that s/he is either utterly clueless or deliberately obfuscating the discussion. Calling systemd an init system is like calling an automobile a cup holder. Not even Lennart Poettering pretends that systemd is anything but the “Core OS” (sic).

What systemd is is an effort to re-create large portions of existing userspace (including login, job scheduling, and networking, just to name a few) inside a single process traditionally reserved for the sole purpose of starting *nix userspace. (Just in case it isn't clear, there is a huge difference between starting userspace (init) and being userspace (systemd).)

At the end of the day, how one perceives this re-creation of existing userspace strongly influences one's reaction to systemd. There are plenty of perfectly legitimate reasons to be troubled by this re-invention of the wheel; they range from the philosophical and aesthetic, to the technical and mechanical, even the purely political and brutally practical.

And that's part of the problem when folks start to “debate” systemd. Very few folks have the chops to think about, much less talk about all of these areas simultaneously. As a result, the discussion becomes fractured and disjointed, in what is literally the textbook definition of bikeshedding. Suddenly, a talking head who's never written a line of code in his/her life offers up an authoritative-sounding-but-utterly-bogus opinion on systemd's maintainability. Add in the fact that folks on both sides (including Poettering himself) act as if name-calling is a perfectly good substitute for empirical evidence, and the “debate” becomes indistinguishable from white noise.

2nd pic :
https://pbs.twimg.com/media/DFgIf2rU0AA83aU.jpg

Analyzing the first pick :
> ryzen 7 box in the background
> Appears the threadripper box is ~4times as big as it
> ryzen 7 box is dimensioned for wraith spire cooler
> Threadripper in a box 4 times its size but no cooler? (unlikely)

Analyzing 2nd picture :
> Box appears to open by a midway seam.
> Threadripper is placed recessed in the z-plane (backwards) and centered in y-plane vertical axis.
> This means when you pull the top of the case it will have the threadripper proc sitting as a belt buckle between a equally portioned top/bottom..
> I'm seeing here something like the cooler resting in the bottom w/ the cooler tubes running up between the foam pieces acting as a hinge w/ the base-plate at the top

Thoughts anons? I need weaponized autism to confirm cooler in retail boxing

Installation:

Wiki:
https://github.com/mpv-player/mpv/wiki

Manual:
https://mpv.io/manual/stable/

Config example:
https://github.com/mpv-player/mpv/blob/master/etc/mpv.conf

User Scripts(including opengl shaders):
https://github.com/mpv-player/mpv/wiki/User-Scripts

Migrating from MPC-HC?

Vulkan(Linux only for now):
https://github.com/atomnuker/mpv

Test vulkan and post logs if it gives you any kind of problems.

For better playback quality paste this in your mpv.conf file:
# Specify high quality video rendering preset
profile=opengl-hq
# Scaler used when upscaling chroma (color information)
cscale=ewa_lanczos
# Scaler used when upscaling video
scale=ewa_lanczossharp

# https://github.com/mpv-player/mpv/wiki/Display-synchronization
# Force video to lock on the display's refresh rate
video-sync=display-resample
# Reduces stuttering
interpolation=yes
# Interpolation scaler
tscale=oversample


Notes: Remove cscale and scale lines if your computer isn't powerful enough.
Interpolation can also reduce framerate drastically.

Mpv uses software decoding if hwdec isn't specified. You may want to enabled it using
hwdec=auto or hwdec=auto-copy.

A side note about scalers:
best quality > ... > worst quality
ewa_lanczossharp > ewa_lanczos > lanczos > spline36 (default) > bilinear

Getting freezes under Windows ?
Add
angle-flip=no
to your mpv.conf.

If MOUSE_BTN3 and MOUSE_BTN4 aren't working in your input.conf, try using AXIS_UP and AXIS_DOWN to control scrollwheel.

To get error logs, please add
log-file=log.txt
to your config file.
Then search the log for "dumb" anything or for [e].

The real question is what did he do for the last 12 years?

http://www.bit-tech.net/news/tech/cpus/intel-principal-francois-piednoel-quits-after-20-years/1/

>Intel principal engineer François Piednoël, best known for his work as the architect behind the dual-processor high-end desktop (HEDT) Skulltrail platform, has announced he has quit the company after 20 years.

>Following a military career spanning 26 years - about which he says 'don't ask, can't tell- François Piednoël was snapped up by Intel in December 1997 to act as its principal engineer. In that role, Piednoël fathered the company's first dual-processor high-end desktop (HEDT) platform, Skulltrail, launched the Extreme Edition brand, optimised performance on the Pentium 4, and aided engineering of the Katmai, Conroe, Penryn, Nehalem central processing unit (CPU) and Sandy Bridge to Skylake, Kaby Lake, Skylake-X and Atom system-on-chip (SoC) product families.
