The signing ups are skyrocketing and I may have found two culprits.

• First: a public endorsement by Pewdiepie in a YouTube Community post https://timesofindia.indiatimes.com/sports/esports/news/sign-the-petition-pewdiepie-backs-controversial-stop-killing-games-movement-as-petition-nears-deadline/articleshow/122200591.cms

• Second, Elon Musk (yes, sigh) retweeted a post about Pewdiepie endorsing SKG.

https://xcancel.com/elonmusk/status/1940020187362717978

This all happened in the last 24h it seems and the SKG campaign has skyrocketed even more since then, check it out here:

Exciting to see the progress though I would have preferred to not have this "personality" be associated with the goal of the initiative...

Hi folks,

I had first written about my attempts here: https://lemmy.zip/post/24041939

I got to learn a lot thanks to some very helpful lemmyist (thank you @chameleon@fedia.io !), but I ran into a wall and tried to persist alone for a while.

While my initial goal is still the same, I'm right now focusing on seeing whether I can rebuild an initramfs myself, excluding any customizations.

My setup is the following:

• OS: Alpine Linux
• Bootloader: Grub
• OpenRC (no systemd)
• Root in a LUKS encrypted partition
• EFI firmware

When booting using the default initramfs:

mytestalpine:~# lsblk -o NAME,FSTYPE,FSVER,LABEL,UUID,FSAVAIL,FSUSE%,MOUNTPOINTS

/dev/mapper/root: UUID="8613c4fe-dbc2-4a4e-9d41-3e7eaa8acf18" BLOCK_SIZE="4096" TYPE="ext4"

Where I'm at:

• I've created a custom dracut configuration file /etc/dracut.conf.d/base-initramfs.conf containing:

add_dracutmodules+=" crypt dm rootfs-block "
kernel_cmdline+=" rd.luks.uuid=luks-73cada8c-5885-4334-b72b-b09b7f919d66 "

• I ran dracut --regenerate-all --force which yielded the following initramfs: -rwxr-xr-x 1 root root 10734241 Nov 27 22:56 /boot/initramfs-6.6.58-0-lts.img
• I did not touch /etc/default/grub which contains:

GRUB_TIMEOUT=2
GRUB_DISABLE_SUBMENU=y
GRUB_DISABLE_RECOVERY=true
GRUB_CMDLINE_LINUX_DEFAULT="modules=sd-mod,usb-storage,ext4 cryptroot=UUID=73cada8c-5885-4334-b72b-b09b7f919d66 cryptdm=root rootfstype=ext4"

• I entered my custom boot entry in /etc/grub.d/40_custom:

mytestalpine:~# cat /etc/grub.d/40_custom
#!/bin/sh
exec tail -n +3 $0
# This file provides an easy way to add custom menu entries.  Simply type the
# menu entries you want to add after this comment.  Be careful not to change
# the 'exec tail' line above.

menuentry 'Dracut entry' --class gnu-linux --class gnu --class os $menuentry_id_option 'gnulinux-lts-advanced-8613c4fe-dbc2-4a4e-9d41-3e7eaa8acf18' {
	load_video
	insmod gzio
	insmod part_gpt
	insmod fat
	set root='hd0,gpt1'

	if [ x$feature_platform_search_hint = xy ]; then
	  search --no-floppy --fs-uuid --set=root --hint-bios=hd0,gpt1 --hint-efi=hd0,gpt1 --hint-baremetal=ahci0,gpt1  515E-70E4
	else
	  search --no-floppy --fs-uuid --set=root 515E-70E4
	fi

	#search --no-floppy --fs-uuid --set=root 515E-70E4
	echo	'Loading Linux lts ...'
	linux	/vmlinuz-lts root=UUID=8613c4fe-dbc2-4a4e-9d41-3e7eaa8acf18 ro  modules=sd-mod,usb-storage,ext4 cryptroot=UUID=73cada8c-5885-4334-b72b-b09b7f919d66 cryptdm=root rootfstype=ext4 rd.shell rd.debug log_buf_len=1M 
	echo	'Loading initial ramdisk ...'
	initrd	/initramfs-6.6.58-0-lts.img
}

This was closely matched to the original boot entry.

• I then ran grub-mkconfig -o /boot/grub/grub.cfg (at this point, not sure whether normal or not, I see mention of the original initramfs, but not mine:

Generating grub configuration file ...
Found linux image: /boot/vmlinuz-lts
Found initrd image: /boot/initramfs-lts
Warning: os-prober will not be executed to detect other bootable partitions.
Systems on them will not be added to the GRUB boot configuration.
Check GRUB_DISABLE_OS_PROBER documentation entry.
Adding boot menu entry for UEFI Firmware Settings ...
done

• When attempting to boot into my entry in grub, I get a blank screen which hangs indefinitely where the only text visible is:

Loading Linux lts ...
Loading initial ramdisk ...
_
EFI stub: Loaded initrd from LINUX_EFI_INITRD_MEDIA_GUID device path

I've tried looking up the message but nothing seems to be giving hints at how I can fix it.

Is there something visibly wrong with what I'm doing? I've removed the quiet parameter and added debug flags to the kernel parameters but I'm doing able to get more information from the failed boot... Thanks!

Linux Mint and Framework Laptops Join Forces

The October 2024 edition of Linux Mint’s Monthly News brings exciting updates, including a significant announcement about collaboration with Framework Laptops, having potential to advance Mint’s compatibility with hardware designed with flexibility, repairability, and sustainability in mind.

For those unfamiliar, unlike most traditional laptops, which are often difficult or impossible to repair or upgrade, Framework laptops are built to be user-friendly, making it easy to replace or upgrade components. This modular approach extends the laptop’s lifespan and promotes sustainability by reducing e-waste.

I landed on this article today about how to configure vLLM for AMD GPUs and it contained this specific snippet:

Meta recently announced they’re running 100% of their live Llama 3.1 405B model traffic on AMD MI300X GPUs [...]

I thought that was an interesting piece of trivia and shows both how important it is for industrial partners to find alternatives to Nvidia and also how much AMD has improved its software suite to enable these use-cases.

Hi folks,

I have Alpine Linux installed in an encrypted LUKS partition. I came across this tutorial which shows how to setup a key in a USB drive and when the drive is inserted and the computer booted, the LUKS partition auto-unlocks with the key on the USB drive.

https://askubuntu.com/questions/1414617/configure-ubuntu-22-04-zfs-for-automatic-luks-unlock-on-boot-via-usb-drive

I would like to setup the same thing but I do not have Alpine linux installed on ZFS, so I'm looking for ways to adapt the instructions.

So far, what I've done is:

1. I've setup the key on the usb stick and I can unlock the LUKS partition with that key.
2. create a /etc/mkinitfs/features.d/usb-unlock.sh script with the following content:

(the echo to /dev/kmesg was to check whether the script did indeed run at boot by trying to print to the kernel messages but I can't find anything in the kernel messages).

#!/bin/sh

echo "usb-unlock script starting..." > /dev/kmsg

USB_MOUNT="/mnt/my-usb-key" # The USB stick mounting point
LUKS_KEY_FILE="awesome.key"  # The name of your keyfile on the USB stick

# Search for the USB stick with the key
for device in $(ls /dev/disk/by-uuid/*); do
    mount $device $USB_MOUNT 2>/dev/null
    if [ -f "$USB_MOUNT/$LUKS_KEY_FILE" ]; then
        # Unlock the LUKS partition
        cryptsetup luksOpen /dev/sda3 cryptroot \
            --key-file "$USB_MOUNT/$LUKS_KEY_FILE" && exit 0
    fi
    umount $USB_MOUNT
done
echo "No USB key found, falling back to password prompt." # this message never appears, despite not having found the key on the usb stick

echo "usb-unlock script ending." > /dev/kmsg

3. I added usb-unlock to the features in mkinitfs.conf:

mytestalpine:~# cat /etc/mkinitfs/mkinitfs.conf 
features="ata base ide scsi usb virtio ext4 cryptsetup keymap usb-unlock"

4. run mkinitfs to rebuild the initramfs. Then reboot to test the implementation, which was unsuccessful.

What am I missing / doing wrong? Thank you for your help!

Edit: forgot to add step 4

Hi folks,

I'm seeing there are multiple services which externalise the task of "identity provider" (e.g. login with Facebook, google or what not).

In my case, I am curious about Tailscale, a VPN service which allows one to chose an identity provider/SSO between Google, Microsoft, Github, Apple and OIDC.

How can I find out what data is actually communicates to the identity provider? Their task should simply be to decide whether I am who I claim to be, nothing more. But I'm guessing there may be some subtleties.

In the case of Tailscale, would the identity provider know where I'm trying to connect? Or more?

Answers and insights much appreciated! The topic does not seem to have much information online.

Hi folks, I'm considering setting up an offsite backup server and am seeking recommendations for a smallish form factor PC. Mainly, are there some suitable popular second hand PCs which meet the following requirements:

• fits 4x 3.5" HDD
• Smaller than a regular tower (e.g. mATX or ITX)
• Equipped with a 6th of 7th gen Intel CPU at least (for power efficiency and transcoding, in case I want it to actually to some transcoding) with video output.
• Ideally with upgradeable RAM

Do you know of something which meets those specs and is rather common on the second hand market?

Thanks!

Edit: I'm looking for a prebuilt system, such as a dell optiplex or similar.

Yesterday, there was a live scheduled by Louis Grossman, titled "Addressing futo license drama! Let's see if I get fired...". I was unable to watch it live, but now the stream seems to be gone from YouTube.

Did it air and was later removed? Or did it never happen in the first place?

Here's the link to where it was meant to happen: https://www.youtube.com/watch?v=HTBYMobWQzk

Cheers

Edit: a new video was recently posted at the following link: https://www.youtube.com/watch?v=lCjy2CHP7zU

I do not know if this was the supposedly edited and reuploaded video or if this is unrelated.

DeepComputing is preparing a RISC-V based motherboard to be used in existing Framework Laptop 13s!

Some snippets from the Framework blog post (the link to which is provided below):

The DeepComputing RISC-V Mainboard uses a JH7110 processor from StarFive which has four U74 RISC-V cores from SiFive.

This Mainboard is extremely compelling, but we want to be clear that in this generation, it is focused primarily on enabling developers, tinkerers, and hobbyists to start testing and creating on RISC-V.

DeepComputing is also working closely with the teams at Canonical and Red Hat to ensure Linux support is solid through Ubuntu and Fedora.

DeepComputing is demoing an early prototype of this Mainboard in a Framework Laptop 13 at the RISC-V Summit Europe next week.

Announcement: https://frame.work/blog/introducing-a-new-risc-v-mainboard-from-deepcomputing

The upcoming product page (no price/availability yet): https://frame.work/products/deep-computing-risc-v-mainboard

From Simon Willison: "Mistral tweet a link to a 281GB magnet BitTorrent of Mixtral 8x22B—their latest openly licensed model release, significantly larger than their previous best open model Mixtral 8x7B. I’ve not seen anyone get this running yet but it’s likely to perform extremely well, given how good the original Mixtral was."

Hi all,

I think around 1 or 2 years ago, I stumbled upon a personal blog of an asian woman (I think) working at OpenAI. She had numerous extensive fascinating blog posts on a black themed blog, going into the technical details of embeddings of language models and such.

I can no longer find that blog and have no other information to go by. Would anyone possibly know which blog I'm referring to? It would be very much appreciated.

Hi folks,

I seem to be having some internet connectivity issues lately and I would like to monitor my access to the internet. I have a homelab and was wondering whether someone had perhaps something like a docker container which pings a custom website every so often and plots a timescale of when the connection was successful and when it was not.

Or perhaps you have another suggestion? I know of dashboards like grafana but I don't know whether they can be configured to actually generate that data or whether they rely on a third party to feed them. Thanks!
