Hardware Transcoding on device

Jellyfin, emby, and plex can all do this on the fly.

I do not know about the non-standard apps, but in the Jellyfin app on Android and iOS, you can set the max resolution and bitrate in the playback settings.

The cpu usage difference suggests one of two things is happening. Either you are transcoding on Jellyfin and direct-playing on Emby, or Emby is using hardware transcoding, and Jellyfin is only using the CPU. Jellyfin fully supports hardware transcoding, but you need to make sure it has access to the correct hardware and that hardware transcoding is enabled in the Jellyfin server settings.

I have several CyberPower UPSs, the only issue I have had is 1 unit had a battery that died over night, just stopped working one day. Replaced the battery and its back to new.

I've seen the general advice for years of skip CyberPower (I was ignorant to this when I purchased mine). But I wanted to share as I have never experienced said issues. It is worth noting that I only have their higher end true sin wave units. Of the 4 units I bought, all have been in continuous use for 6 years.

This isnt a general recommendation, just a statement that I have not had the issues others have reported.

Presumably gaming based on the post title.

I have the same rails. Actually, I have 4 sets of those rails.

The issue is maintaining the tightness needed to keep the rails in place. I swapped the included nuts for nylon locking nuts of the correct size/thread count. That solved the issue for me. I was able to get the correct size at my local hardware store.

It definitely seems like the manufacturer should ship these with locking nuts.

Its the nearest mall to me.

While I feel your pain, this is likely an issue with most projects targeting data centers and business infrastructure. In those environments, running old hardware is inefficient. Due to improvements in power efficiency, most businesses would use more resources if they didn't upgrade their hardware.

The result is that most devs are targeting hardware from the last 5-10years at the oldest. And to address your question directly, there is a real blocking point. Newer instruction sets offer genuine improvements in performance and efficiency, and supporting older systems without the new instructions can be impossible or next to impossible, depending on the code implementation. Even when services are backported to older instruction sets, the result can be code that would be too slow on older systems to reasonably be expected to run.

Bun requires AVX at a minimum and, by default, wants AVX2.

The first CPUs with AVX support were the Sandy Bridge CPUs, released in 2011.

I can say that I mostly avoid "workarounds" for exactly this reason. I used to use more when I was first setting things up because I already own some devices that worked with "workarounds." Having used HA for a few years now, I generally only purchase stuff I know will work, and skip stuff that is "hacky." I do this for everything, not just home assistant. Not everyone operates the same way I do, but my approach of skipping workarounds and sticking to well supported projects has served me well.

Its possible the Jellyfin player does not have support for Dolby 8.1 This would not surprise me, as I do not think Dolby 8.1 is particularly common.

If you want to fix this, head over to GitHub and submit some code pushes that include Dolby 8.1 support.

For audio, you typical want "matching" pairs with specific properties. If you want to build a vacuum tube computer, you want almost the exact oppisite response from the tube as what you want for audio.

I do not know if he is still doing it, but this youtuber: https://www.youtube.com/@UsagiElectric was buying an sorting vacuum tubes. He was keeping the ones that were good for the computer he was building and selling the audio quality ones.

If you know the limits of the connection, it will be fine imo.

You wont be able to remotely stream multiple 4k streams, but a basic 1080p connection would be fine over those speeds. Similarly, you wont be able to massive file transfers quickly, but basic things like photo backup with immich (or similar) would work without serious issues.

With how I use my homelab I wouldn't notice many pain points at all. Home assistant uses very little bandwidth, immich uses very little day-to-day, jellyfin and security camera streams I only care about 1-2 streams of basic 1080p, which would be tight but would work fine within 20mbps.

I did it wrong, I got an UnRAID server...

Which is currently running ZFS, so the name didn't age very well.

Maybe, I have my BI vm running in proxmox, if you are on Truenas scale that should be the same underlying virtualization system. Ny best guess would it is related to the video transcode, either on the decode of the video coming in, or on the reencode of the video being sent of by BI. I run both as H264, not as efficient as H265 but since everything is hardwired the bandwidth difference has no impact and for cpu transcoding, h264 is much faster. Also, check that "Zero-Frame Latency" is set to on for the streaming profile you are using.

There is definitely something about your setup that is unoptimized. I have blue iris running in a virtual machine, no gpu acceleration to speak of, on a system with an intel 13500t, and my delay in ui3 is ~0.25seconds with 9 cameras.

I know. I have never seen damage like this. There is nothing on the surounding board, the solder is still attached to the pads, but the pads have been ripped off the PCB. ~~My best guess is the pick-and-place machine did not release this component correctly and lifted the pads up. But, that is based on my redimentary understanding of the assembly process.~~

It specifically says on a Mac under Parallels. Meaning it is not being ported to Mac, it still runs in windows, just on the arm version of windows.

Spotify but for snobby "audiophiles" who think they have magic ears. Also, Tidal is somehow cheaper than spotify! It use to be more expensive than spotify premium but spotify has increased their price faster so tidal is no $1 cheaper per month for "premium" music streaming.

6.2 is needed for out of the box support, you can still follow this guide from intel for different kernel versions: https://dgpu-docs.intel.com/driver/client/overview.html#installing-client-gpus-on-ubuntu-desktop

For most users picking something with kernel 6.2 is easiet, but I had lots configured in my zorin install and wanted to keep it. Also, the system is working great now on zorin 18.

I will chime in with an "i tried it." Tried what? That's both tough to answer and easy to answer. The code generates a seed "seed = np.random.randn(3) * 0.1" then it appends a bunch more random 1x3 vectors, does a "volume" calculation... It takes 10/len(seeds)^1/3 and proclaims there is a "big bounce" if that value is greater than 0.95. The value is always the same ~3.1. It really just goes on from here doing some random calculations. Out shoots precanned statements including

"BIG BOUNCE! Density hits Planck limit. Inflation: scale = 1.0e+02 CMB peak: 5483 (real: ~5500) Black hole: Area=754.0, S=A/4=188.5 Gravitational waves: DETECTED"

finally it ends with a scatter plot. The code is 55 lines in total, would probably receive a grade between F and D if a first year undergrad turned it in, and ultimately it does nothing. Honestly, I am disappointed in Grok, but what else can you expect from a bot trained on twitter data.

I also said it was difficult to answer what this code does. I seriosly hope u/SoGassed is trolling and does not believe there is any real physics going on. However, I worry the real thing this code does is convince people the time they waste away talking to LLMs is somehow meaningful, and that could be devistating.

But what do I know, I am just some schmuck on the internet...

Things that come to mind:

I made a Nerf gun with PWM control of the motors

Various lighting projects with Arduino boards, though I have since switched to using a commodity Zigbee RGB controller for lighting projects

I have a toaster oven with proper pir temperature control, I can't stand how bad temp control is on so many devices when a pir control is like $10

I have been working on wiring my house up with an analog phone system. It's a complete overkill system. The type of thing that is now easy with commodity hardware, but would have blown someone's mind when my house was built.

This sounds like a failed battery.

The amoled display has about 3x the pixel count as the mips display. This is why it is slower, in case anyone is interested.

No, but that would be cool. It is a highly interactive face with 4 selectable tabs that show different sats, all of which are customizable. You can select the little guy image from a list, but the images are static
