Need help: USB unlock LUKS on Alpine Linux

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). ```sh #!/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

Identity provider privacy

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.

[Question] Recommendations for a SFF backup server

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.

What happened to Louis Rossman's live yesterday?

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.

New Mistral model is out

From Simon Willison: "Mistral [tweet a link](https://twitter.com/MistralAI/status/1777869263778291896) 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!

The Wild Hunt is a fantastic game

Just wanted to share my appreciation of the game. I grabbed a copy of this game a year ago, taking advantage of a sale and ahead of the massive update. Then forgot about it, never touched it. Fast forward a year later, and now I got a steam deck and decided to dive into the game. I love it. I'm just a few hours in but I can already say this is among my favorite games. The broad openness of the world, the level of detail, the characters, the interactive dialogs, the items, the strategies, the game mechanics. It's a very involved game. It really is up there. Thank you CDPR for this game and this remake.

25 FPS default to 50 Hz instead of 75 (OLED)

I was exploring the fps and refresh rate slider and I realized that when setting the framerate limiter to 25, the refresh rate was incorrectly set to 50Hz on the OLED version, when the 75 Hz setting would be a more appropriate setting, for the same reason 30 fps is at 90 Hz and not 60 Hz. Anyone else seeing the same behavior? Is there an explanation I'm missing here?

Looking for a video on quicksync performance impact of iGPU passthrough

Hi folks, I'm looking for a specific YouTube video which I watched around 5 months ago. The gist of the video is that it was comparing the transcoding performance of an Intel iGPU when used natively, compared to when passed through to a VM. From what I recall there was a significant performance hit and it was around 50% or so (in terms of fps transcoding). I believe the test was performed on jellyfin. I don't remember whether it was using xcpng, proxmox or another OS. I don't remember which channel published this video nor when it was published, just that I watched it sometime between April and June this year. Anyone recall or know what video I'm talking about? Possible keywords include: quicksync, passthrough, sriov, iommu, transcoding, iGPU, encoding. Thank you in advance!

ZFS dataset configuration for a movies and tv shows library? Very heterogeneous data

Hi y'all, I am exploring TrueNAS and configuring some ZFS datasets. As ZFS provides with some parameters to fine-tune its setup to the type of data, I was thinking it would be good to take advantage of it. So I'm here with the simple task of choosing the appropriate "record size". Initially I thought, well this is simple, the dataset is meant to store videos, movies, tv shows for a jellyfin docker container, so in general large files and a record size of 1M sounds like a good idea (as suggested in Jim Salter's [cheatsheet](https://jrs-s.net/2018/08/17/zfs-tuning-cheat-sheet/)). Out of curiosity, I ran Wendell's [magic command](https://forum.level1techs.com/t/zfs-metadata-special-device-z/159954#introduction-1) from level1 tech to get a sense for the file size distribution: `find . -type f -print0 | xargs -0 ls -l | awk '{ n=int(log($5)/log(2)); if (n<10) { n=10; } size[n]++ } END { for (i in size) printf("%d %d\n", 2^i, size[i]) }' | sort -n | awk 'function human(x) { x[1]/=1024; if (x[1]>=1024) { x[2]++; human(x) } } { a[1]=$1; a[2]=0; human(a); printf("%3d%s: %6d\n", a[1],substr("kMGTEPYZ",a[2]+1,1),$2) }'` Turns out, that's when I discovered it was not as simple. The directory is obviously filled with videos, but also tiny small files, for subtitiles, NFOs, and small illustration images, valuable for Jellyfin's media organization. That's where I'm at. The way I see it, there are several options: - 1. Let's not overcomplicate it, just run with the default 64K ZFS dataset recordsize and roll with it. It won't be such a big deal. - 2. Let's try to be clever about it, make 2 datasets, one with a recordsize of 4K for the small files and one with a recordsize of 1M for the videos, then select one as the "main" dataset and use symbolic links for each file to the other dataset such that all content is "visible" from within one file structure. I haven't dug too much in how I would automate it, but might not play nicely with the *arr suite? Perhaps overly complicated... - 3. Make all video files MKV files, embed the subtitles, rename the videos to make NFOs as unnecessary as possible for movies and tv shows (though this will still be useful for private videos, or YT downloads etc) - 4. Other? So what do you think? And also, how have your personally set it up? Would love to get some feedback, especially if you are also using ZFS and have a videos library with a dedicated dataset. Thanks! Edit: Alright, so I found the following [post](https://jrs-s.net/2019/04/03/on-zfs-recordsize/) by Jim Salter which goes through more detail regarding record size. It clarifies my misconception about recordsize not being the same as the block size, but also it can easily be changed at any time. It's just the size of the chunks of data to be read. So I'll be sticking to 1M recordsize and leave it at that despite having multiple smaller files, because the important will be to effectively stream the larger files. Thank you all!

Dave2D preordered the L16 and talks price

www.youtube.com

Dave2d who's been supportive of Framework preordered the Laptop 16. He's a bit concerned about the pricing and questions the upgradability of the Laptop 16 specifically. Personally I understand his point, but I think the upgradability alone is probably not a good reason to buy the Laptop 16. It's always been a package, which includes: * repairability * modularity * support of the movement/mission * the versatility of reusing parts for other use cases (e.g. the motherboard as thin-client) * a laptop that actually does not have Linux as an afterthought * the openness with the expansion card and (hopefully expansion bay) ecosystem * and maybe even more? It's true that the laptop is expensive when you compare specs for specs but that was not the reason to buy it either. Do I wish it was cheaper? You bet. But like with all new startups, if it works out, if it scales, prices could come down. Long live Framework!

Possible LTE cat 4 modem chips

I'm curious and am playing around with a new EDA tool and am looking at practicing by designing a PCB which should be roughly 28x26mm footprint (give or take a few mm...). It should be an LTE cat 4 device, connected by USB type C for the framework laptop and is unlikely to include antennas. Where I struggle is identifying potential modems to use. The only one even remotely close is the u-blox LARA-L6, which is 24x26mm. What alternatives are there? I am trying to see what gets sold in these USB dongles but there is little info. The few I have identified seem to make use of the Qualcomm 9207, but its's unclear to me if its a ready chip (which is what the MDM9207 is?) Or if it is an IP core to integrate in one's own chip? A video I came across seem to indicate it (the MDM version) is tiny: https://www.youtube.com/watch?v=ToCyUCIoXEM at 2:13 But will probably needadditional things to be integrated and I created an account at Qualcomm but they won't give anything unless I'm certified from a company to be a customer and actually integrate it...
