Yesterday Framework unveiled a small form factor desktop based on Halo Strix.

Halo strix seems to require memory with high bandwidth, specifically 256-bit LPDDR5x, according to the specs.

Allegedly, the company said they tried to find a solution to use modular memory (e.g. lpcamm) but it did not work out signal integrity wise (@36:10, from the unveiling video above and here).)

So I'm wondering exactly, why not?

It seems LPCAMM2, offers a 128-bits bus and can scale today up to 7500-8500 MT/s.

This would offer 7500 x 128 / 8 = 120GB/s. Would it not have been possi

We’ve been hinting that this year is going to be huge, and we’re ready to share why… in two weeks on Feb 25th, at our Framework (2nd Gen) Event! We’re holding this launch event live in San Francisco and streaming to our YouTube channel at 10:30am Pacific that day. You can sign up now to get notified when the stream starts. The last time we held a live launch event was in March 2023, when we unveiled Framework Laptop 16 and two new versions of Framework Laptop 13. It’s been amazing seeing the interest in these products and the incredible ways the community has been using and extending on them. We’ve been heads down working for the last two years on an even bigger set of announcements.

For this event, in addition to bringing in press and partners, we’re opening a pool of invites to the Framework Community to attend the event in person, meet the team, and get hands on with our newest products. If you’re a current Framework fan and are in the

Just landed on this article by Phoronix on an AI accelerator in an m.2 drive format.

This one is from memryX and seems to be rather mature and capable though mostly low power.

I can't stop thinking that this may be a great usecase for the new expansion bay for the Framework laptop 16, with it's two additional full size m.2 slots. Would be very interesting to see whether two of these could be combined and used jointly and how much acceleration it provides compared to the AMD CPU alone.

Anyway, just sharing because I thought it was cool.

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 @[email protected] !), 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:

 undefined

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

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.

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" #
  

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.

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!

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?

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!

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).

Out of curiosity, I ran Wendell's magic command 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

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
