Why is trusting someone with my DNS queries better than installing an adblocker extension?

Hello, please, help. How to enable crash dumps? There is no files at all in my /var/crash at all
Ihor

1- CPU cycles and latency
2- mostly CPU intensive appilications
If you are talking about a workstation/PC ... You won't notice any improvement. If you NEED low latency (professional audio/video) you're better off tweaking the kernel with certain options ... But then again, latency might be due to the underlying HW (firmware, HW you've got) you've got.
Recompiling the kernel was a thing in the early 2000 when certain HPC vendors had "jitter free" kernels. That was good for very specific HUGE MPI workloads with A LOT of nodes and communication between them. But then again, you would need to also:
- have dual-rail IB network
- disable ALL unnecessary services that create noise on the network ... NOT kernel related ;)
- have really well optimized code
- have really well optimized job scheduler scripts
- have optimized math libraries
- ...
So, as you can see, there's a lot of user space tweaking also required
BTW, this is NOT real-time we are talking here. That's something else ;)

/var/crash should hold dumps by default iirc
Ihor
ɴꙩᴍᴀᴅ
It is empty
Set
dumpdev="AUTO"
At your /etc/rc.conf to enable crash dumps.

Hmm. How do you have Swap setup?
ɴꙩᴍᴀᴅ
ɴꙩᴍᴀᴅ
Which architecture is the server running on? x86_64 or arm?
Ihor
Ihor
I have swap partition
Ihor
ɴꙩᴍᴀᴅ
Alright. One last try hehe. Let's specify the path to dump at /etc/rc.conf add:
dumpdir="/var/crash"

Unicorn Unix Magic Tricks | Thorsten Ball
We'll take a look at small snippets of the Unicorn source code and see that it isn't magic, but plain old Unix: forking, signal handling, pipes (even self-pipes), pre-spawning, master-worker architecture, file descriptor handling, system calls, the classic socket/bind/listen/accept sequence, Unix sockets, PID files and a lot more.
Unicorn is full of Unix. By studying its code we do not only learn how one of the most important pieces of Ruby infrastructure works, but also how Unix systems work. The talk will provide you with a foundation for programming in the Unix environment and show you how to leverage the powers of Unix.

Welcome @MA6669420 What brings you into FreeBSD? Daily driver?
Anonymous
thanks! yeah, i recently reinstalled FreeBSD and I'm planning to daily drive it from now on because i was curious about its state these days
Anonymous
last time I tried it was using GhostBSD which is a rather beautiful OS based on FBSD
ɴꙩᴍᴀᴅ
Cool!
ɴꙩᴍᴀᴅ
Unless you are on the newest hardware out there, you should be able to run FreeBSD without issues at all.
Organization's roadmap has been recently published here https://freebsdfoundation.org/blog/technology-roadmap/
So you can take a look at the project status and where is it looking at.
If you want to discuss and compare BSD with Linux, we have an offtopic room where you can ask freely https://t.me/freebsd_offtopics

ah, i see, thank you very much

right now im just having an issue where im trying to chroot to my original linux installation because when I installed FreeBSD, it overwrote the grub that I set up on it, and I dont want that
Anonymous
i think i may not need to chroot, but im unsure how else i'd tackle it
Anonymous

yeah, thats what I'm attempting

I've been unsuccessful though

like sysfs, procfs, devfs

let show you an example of chrooting from arch into gentoo, and making gentoo a fully working system
Anonymous
mount -v --types proc /proc /gentoo/proc && \
mount -v --rbind /sys /gentoo/sys && \
mount -v --make-rslave /gentoo/sys && \
mount -v --rbind /dev /gentoo/dev && \
mount -v --make-rslave /gentoo/dev

interesting

why not just use a Linux liveCD for chroot and grub installation. try out Ventoy for liveCD, save a lot of time `dd`ing ISOs into flash drive, supports legacy Bios and UEFI and covers most Linux distros and BSDs.

Q
I am trying to install GhostBSD but when I get to the password step in the installer the X server freezes then crashes with those logs (I actually succeeded in passing the password step but it crashed right after, also note that the installer freezes before X does)
I am running it on my iGPU which is an Intel Iris Xe (so not supported according to the documentation) should I push those logs to FreeBSD devs?
Q
Forwarding this here since I guess the support on Intel iGPUs is the same

And the driver supports Iris and Iris Pro according to the manual, not Iris Xe

Not directly FreeBSD-related but maybe some REGEX-wizard might help me:
I wrote this command:
for f in *.mp4 ; do cp -v $f $(mediainfo ${f} | grep -i encoded | sed -e 's/`Encoded date \: UTC //g' -e s'/://g' -e 's/ /_/g').mp4 ; done
Now cp says cp: target '15:15:03.mp4' is not a directory (as an example)
And I'm confused about where the error hides...
Badugar
Or zsh complains about "bad pattern".
K
Never mind I’m stupid
i686
zsh is a bit picky about substitutions
Badugar
Ok, found the error. mediainfo shows "Encoded date" 3 times, "General", "Audio" and "Video". I have to use uniq 😅

Hi! I installed xf86-video-intel-2.99.917.916_1,1 but i keep getting the error "no screens found(EE)" when starting xorg. Is there anything more I should do?
