Homelab upgrade (...and fail) in c/homelab@lemmy.ml

The height of the drive cage is wider than the case. Its a surprisingly compact case

Homelab upgrade (...and fail) (lemmy.ml)
 

My main homelab server runs a bunch of stuff but was a little limited in the hardware department.

Here's the overview of the upgrade. Old -> New CPU: i7-3370K 4c/8t -> xeon e5 2630L 8c/16t RAM: 16 GB mixed non ECC 1333 DDR3 -> 32 GB Micron DDR4 2133 (running at 1866) CPU COOLER: AIO -> air cooling MB: No idea -> Asrock x99 extreme 4 with 10 SATA ports!!! GPU: None -> RTX 610 passively cooled

Runs: Nextcloud, pihole, unbound, security stuff like fail2ban, hosts a couple small databases, VPN.

This upgrade will allow for expandability in terms of upgrade CPU cache, bus speed, maximum allowed RAM (32 GB to 128), and extra cores to maybe do some light compute with when I'm writing some code without sacrificing performance of other services. All of this while having similar "net" TDP (I didn't measure either idle power draw).

Here's where the fail comes in. I got the whole original machine and drives for free from a recycle pile at my old job. I threw in a drive cage where the DVD drive use to be and it fit like a glove! Felt like a really cool "sleeper" server build with hot swap drive cages. My new mother board is wider by an inch and the drive cage covered the 24 pin connector. So now my drive cage hangs out and is supported by zip ties and I can't close my case in the front lmao... See linked pictures so you can laugh at it with me: https://imgur.com/a/1XqALZ4

So I'm looking for either a new case or a relatively small 4-bay drive cage thats cheap. The total ive invested in this build after this upgrade is ~$200 and I don't want to spend a ton more so I'm wildly disappointed at my oversight. Any advice or suggestions would be appreciated!

AI comes up with battery design that uses 70 per cent less lithium in c/technology@lemmy.world

I wish I had a solution. But its the same with all shitty titles, you have to hope people click and read the article/comments in order to get the nuanced information.

This post title is pretty bad. Even the news article says "Scientists use AI [read: machine learning] to [come up with new battery idea]".

I did that for a while but some features were limited and also required internet. It was also slower in general.

Improvement to Libre Impress or an alternative that is better. PowerPoint is one of the only things keeping windows around for me.

Mine are also literary. They are references to Sanderson's cosmere series and the names chosen reflect their purpose.

I have an old optiplex SFF which is called Preservation because it has a disk drive for ripping media, it's a disk wiping station for repurposing drives, and it's old hardware I'm preserving.

What's the point of buying new phones every years? in c/asklemmy@lemmy.ml
[–] world_hopper@lemmy.ml 3 points 2 years ago

I'm only replacing my Galaxy S8 because apps are beginning to malfunction and some apps are even emailing me to warn about end of software support for my phones OS, which I cant upgrade because of the age of the phone lol.

I think you would notice a difference between models with the specs you list at the bottom of the post though...

Sarah Silverman and other authors are suing OpenAI and Meta for copyright infringement, alleging that they're training their LLMs on books via Library Genesis and Z-Library in c/technology@beehaw.org
[–] world_hopper@lemmy.ml 4 points 2 years ago

Do you know what library genesis and z-library are?? They are literally libraries of pirated materials.

And yeah they can read the book, but shouldn't be able to use its content in a commercial way (e.g. make money) off of its contents without the permission of the writer/copyright holder.

A lot of these comments are missing a large point which is that, if the claim is true, the books are being pirated and then effectively used for a commercial application.

So the authors are losing money through this process and did not give their permission for their work to be used in a commercial way.

The decision of this case will be wildly important for the development of AI.

Mixing non-ECC RAM speeds in NAS with software RAID (lemmy.ml)
 

I have a NAS with a 3rd gen i7 and 8 GB (2x 4GB DDR3 1600 MHz) of non-ECC RAM which has a RAID 5 mdadm array. I don't have any memory issues but I could as I add more services. I have two other 4 GB sticks 1333 MHz DDR3 which I have no other use for. I don't care about the minor speed decrease. I know mixing is generally a bad idea.

But, all of the posts I've seen about this are in regard to playing games or in production environments with server-grade hardware (ECC RAM, maybe hardware RAID). Not in a consumer hardware-focused homelab-type environment

What do you all think? Has anyone else done something similar? Am I asking for trouble here?
