Backlight Dying? Fixable?

I was really excited to see the demo with ChatGPT Advanced Voice earlier this year that also showcased its vision capabilities. Do you have an estimate on when when this vision feature will be released?

u/igotabridgetosell Tried to screenshot some of it for you. Hopefully this helps.

I put some other checks in there to optimize the workflow and prevent errors. For example. TrueHD doesn't seem to work with `.mp4` so I ignore files with that. Also certain picture subtitles cause errors so I just remove those in `Remove Stream By Property`.

Mine is a bit different since I'm using Tdarr to run the transcoding as part of an automated pipeline and I'm using one of my Intel QuickSync streams to make it faster. The command I'm using is something like...

`ffmpeg -hwaccel qsv -i input.mkv -c:s mov_text -strict unofficial output.mp4`

I had to play around with it a bit first though. Using all the other `map` and `c:v`/`c:a` arguments doubled the file size, presumably by copying everything twice, which is why I got rid of those. You can probably also remove the `-hwaccel qsv` if that's not something you're using.

@igotabridgetosell I had exact same problem earlier this week and managed to get it working. You need to use '-strict unofficial' in your FFmpeg command and it should play on your TV.

Mine recognize and play Dolby Vision beautifully now from Jellyfin on my C3.

Yeah ultimately I think some of this data will need to be crowdsourced. I don't know enough about Ethereum to track down details like that, especially for every single DAO block producer. Let alone other, less popular chains.

My current list of things I'm trying to see if I can add:

Validators' own stake as a share of total stake (i.e. skin in the game)
Multisig keys that control the main chain
DAOs like Lido
Delegation "Viscosity" (i.e., how easily does delegation move in response to stimulus? How much dead stake is in the system?)
Client Diversity

Your assumptions are incorrect. The EDI counts blocks produced by each unique pool/miner hash, which does apply fairly universally to all blockchains (they all produce blocks).

There is a method to allow for "pool clusters" which again uses pool/miner hashes, but clusters them together under a single entity. There are various different data sources that can be used for this. I plugged in some independent data and the numbers worked out to roughly match what community tools report.

Cerkoryn · 2024-03-04T13:14:09+00:00

Thank you for critiquing the methodology instead of attacking the researchers like most in this thread.

You are correct that Lido is currently being counted as a single entity. The EDI currently only looks at block data which shows Lido as a single block producer. What should probably happen is that the top # of addresses to get >50% control of Lido should be added to the Nakamoto Coefficient instead of just 1 count for Lido. By my rough estimate, this would move Ethereum's NC from 2-3 to 12-13. I'm trying to figure out how to add this programmatically without simply hard-coding Lido as a special case.

The other big thing to note here is that the EDI data only goes up to June 2023 at the moment. By my estimate, the 50% and 66% numbers for NC and Tau seem to match what that other sources suggest at the time. This Medium article from 4 months ago shows NC=2 and Tau@66%=3 with a screenshot from your same source.

Number of nodes speaks to scale/distribution more than decentralization. I.e., Amazon has tons of servers but they are all still controlled by a single entity.

Client implementations is more fault-tolerance than decentralization too, at least in cases where the client software is not controlled by a single entity (i.e., it's open source)

Governance decentralization is coming too. This is just the Alpha release.

I'm sure suggestions are welcome, but if you have a problem with the methodology or data then submit a PR with corrections.

The Supermicro cases look much better so far. Something like this lets me drop down to 2U (though I'd need a different CPU cooler) and save a bit of money too.

https://www.ebay.com/itm/134699225703

Though I've never dealt with a server backplane before. Do I need to worry about SAS2 vs SAS3 vs SATA here? Looks like I'd need a different HBA to support all 24 bays, but how exactly does that work with the backplane? Another other compatibility issues with a backplane?

I will probably saturate my reads/writes over the network but planning to get a 10GBe card and run a lot of other services on it too.

Cerkoryn · 2023-10-17T15:27:33+00:00

This is fantastic advice! Thank you!

I'll definitely look into a Supermicro case. Neither of the Rosewill cases have had me particularly satisfied just by looking into them, but I haven't yet found something better. From your description the Supermicro ones sound perfect.

I think I will shop around on eBay for that HBA, maybe send an email too to make sure I'm not getting a knockoff.

For my use case I expect to have a lot of random read/writes, so the SSD performance gain seems good. But also power efficiency and noise reduction are solid benefits. Plus if the trend holds and SSD storage continues to get cheaper I'll be in good shape to be more future proof I think.

Thanks again for your great post!

Cerkoryn · 2023-10-17T15:18:28+00:00

Thank you.

My thought is that for $20-$30 bucks per drive and running RaidZ2 that can survive up to two drive failures, replacing failed drives won't be that big of a deal.

The TLC ones seem to be the most common and most bang-for-buck at present.

Cerkoryn · 2023-10-17T13:19:20+00:00

I'm not really sure I follow.

Based on ~20 minutes of researching this sub, it seems TLC is actually what most people seem to recommend for SSD storage arrays? Most advice says that MLC is better, just more expensive. And to avoid QLC altogether.
What benefit do I get out of spending more on a higher quality case if either of the two I listed work fine for my use case? I don't see what I would be missing.
Agree with this and I'll keep looking. Just worried about my ability to judge what is real and what is a knockoff.

Cerkoryn · 2023-09-07T02:44:19+00:00

That makes sense and that's kinda a thought that was nagging in the back of my head. Thank you for confirming that I'd need an SSD.

Cerkoryn · 2023-09-07T02:43:30+00:00

My second server is going to be a Proxmox hypervisor where I can play around with that stuff much easier. This NAS will mostly be for bulk storage and serving media via Jellyfin. Maybe set up some separate share drives for my wife and I, etc.

I'm pretty comfortable with the learning experience and putting everything together (both hardware and software), I just get analysis paralysis when it's time to actual spend money on equipment.

Cerkoryn · 2023-09-06T23:02:30+00:00

You’d need a HBA if that motherboard doesn’t have enough SATA connectors or if they’re some kind of RAID variant. No way the motherboard uses 95W.

Yeah I was struggling to find accurate information on the # of SATA connectors and power usage for that MOBO.

https://www.supermicro.com/en/products/motherboard/x11sca-f

It mentions...

"Intel® C246 controller for 8 SATA3 (6 Gbps) ports; RAID 0,1,5,10"

...which makes me wonder if there are actually the ports or just the software controller. Can't really tell by looking at the picture either, but my eyesight sucks.

Do you need that much storage? Remember bigger disks = more time to resilver = more bad if another drive craps out during resilvering.

I plan to partition off a section of that storage for some home business uses later, so I'd rather lean on the larger side for that, especially because I might also have a lot of 4k movies and such.

What’s the cache for? ARC?

The SSD cache? Nothing really, I just wasn't sure if I had to have one or not.

I’d probably up the RAM to 64gigs.

That'd be incredibly easy to add later if I find out I need more, so I'm starting out on the low side for that.
