On Regular Maintenance

As I've mentioned before, I run a Proxmox VM server at home. It's a fun insanely-overpowered bit of hardware I've cobbled together over the years from what I had on hand or could get for as close to nothing as I could.

One foreseeable problem with the setup is I initially set it up with cheap consumer SSDs for boot drives. Proxmox is very heavy-handed with SSDs and I've been watching the wearout on one of the drives steadily tick higher.

Well the day finally came. I woke up to an email from the server informing me of a SMART error on one disk: wearout had hit 101%. Definitely time for replacement before things go south.

Luckily I had been procrastinating was prepared for this event and had new SSDs on-hand to swap in.

So a fun evening of watching paint dry ZFS resilvering followed. Sure beats data loss.

This looks far more illicit than it actually is

I planned on doing 16mg E -> 30 of 24hr doses, but they ended up being a little too large. I've divided them up into 40 days worth instead, which the original formulation called for.

In total, I used 8x2mg Estradiol with 1.85g of 99.8% guar gum. I ground the two together until very very fine and gradually added water until cohesive. This made a disgusting sticky mess, but folding it like dough on the paper plate helped. Now the pellets should dry for about a day, and should then be able to stick securely onto the gums for a day.

On December 17th I'll be taking labs to measure my estrogen and testosterone levels. Until then from now (November 7th), I'll be taking these every day instead of my 4x2mg daily.

I'm currently saving for the set to synthesize estrogen myself, as well as getting what I can from the college. The largest expense is going to be the Aromatase CYP19A1, which is roughly $1000/900£ per gram, and the sterile environment.

This video makes an interesting argument for HexOS which I briefly discussed in a previous post that this is the OS for those who don't want to tinker but could use a home server. The example case was a friend who runs a Plex server on a Mac Mini–that HexOS might be a better answer.

The Flaw

I think the flaw here is: if you need something like HexOS to make the idea of a home server a good one–then you are not the market for a home server. You are better off using something like a Synology or Terramaster product etc do the same work.

There are people who should get home servers for their home labs and I suspect that the overlap is almost zero with HexOS. I think this is just sort of the flaw with a product like HexOS. I am paying for software to run on hardware that I am only marginally likely to own or want to own. This paints the picture that the real market is those who have the hardware already and just want to simplify things–which again I think is pretty small.

Furthermore, I would suspect anyone who actually needs a home server is going to find this product quite expensive given that it is just software. As an example: at $199 you are roughly a third of the way to a diskless Synology DS923+ box. Given that with HexOS you will need some good hardware for the underlying ZFS and TrueNAS requirements my guess is you will spend more money to get your relatively simple needs met–with less support and a no track record company.

Bottomline HexOS is in a tough market segment because they are software competing with the likes of Synology, Terramaster, Ugreen etc. Furthermore, the home server market is very specific in its general character and it is hard to see how HexOS changes the user base for the home server, or makes those users a better candidate for the home server vs what they likely already do or the normal argument for something like a standard NAS option.

not me spending 2k on a custom NAS

its gonna be a bit overkill for a NAS but I could also use it as a general server for vpn, mc, etc

There should be no use of these two names without my permission. Also, all of Severus and Elizabeths' childrens names are mine and mine alone. I also do not condone any copying of this.

SNAPE HOUSEHOLD- ELIZABETHS' LAB

🩶🩶🩶🩶🩶🩶🩶🩶

Elizabeth scanned the paper in front of her, which listed out the ingredients and concentrations for said ingredients for her werewolf potion in front of her. As she had finally told Hermione that she would be releasing the potion to the public, she was hopping to get rid of the vomiting side effect and finally reach perfection. 

Nineteen years she had been working on the potion. So many failures, so many milestones reached. And now, she had finally reached the goal she had set for herself when she was eight years old. 

But her mind would not settle on the potion at all. Instead, she was thinking about the vision she had seen, back on the platform. It hadn't been important really, in fact it was really a nothingness scene. Just Albus and Scorpius sitting on the train together, eating Peppermint Imps. 

Her question was, 'Why'? Was Dr. Gates messing with her again? Was this a book from the other world? Why was she receiving another 'vision' after nineteen years of nothingness. 

And yet, she hoped for more. She hadn't even realized that she had missed receiving visions until now, when she had received one after so much time had passed. She missed having them, it was like greeting a long lost friend. It was like a part of her that she had found again. 

Not a boom-bap rapper, I'm not stuck in 1990 I like Wu-Tang, but that vibe is kinda old and grimy Not a conscious rapper, all those rappers sound like SJ dubs Not a gangster rapper, cool enough without being a thug I'm not country rap, I don't play guitar, I don't drive a truck I don't chew tobacco, get the Chevy stuck ten feet of mud I'm not horror-core, I don't paint my face I don't trip, I can only be myself, and I am Tom Macdonald, bitch

The radio played the song, one by Tom Macdonald. Just as Dr. Gates had explained, she had grown to love the Canadian rapper and all of his music. When she had difficulty with anything, she would put it on and just listen to it. To be completely honest, she had a hard time listening to anything else. 

The door opened, quiet footsteps on the stairs as Severus approached her from behind. She closed her eyes for a moment, before glancing over her shoulder to acknowledge him. 

Pumping Eminem, don't mean that all you boomers really rhyme

"Hey." Severus said, glancing over at the radio. He did not share her taste in music at all. 

"Hey." She said softly, tapping her fingers on the paper. It was like a subtle gap was between the two of them, one that hadn't been there this morning. She quirked her eyebrows quickly. "Uh, so I'm releasing the werewolf potion to the public. Just was going over this to see if I could get rid of the vomit side effect." 

"Yeah. . ." Severus murmured. "You'll figure it out. And I'll help if you need me to." 

To polite. They were being to polite. 

"Look, Elizabeth. . . what did you see?" Severus asked, taking a seat on the stool across from her. Potions bubbled around the lab, different ones that the both of them were working on. New creations and old, common ones and uncommon. The bubbling was all that could be heard for a moment. 

"Nothing." Elizabeth said softly with a shrug. "It was nothing." 

I ain't emo rap, I ain't shedding tears, I don't cut myself I don't romanticize suicide or poor mental health I ain't backpack rap, that's my grandad's rap Please, don't take this as a diss, I'm just Tom Macdonald, bitch

Severus glared at the radio and couldn't help but let out a frustrated sound. "Nothing. Right, like the same nothing you say when I ask about your nightmares? The ones where you say Cedrics' name out loud?" 

She flinched. She could still feel the cold hands choking her, Cedrics cold, dead, blue eyes staring into hers. 

"You have no idea what you're talking about." She whispered, focusing solely on the paper in front of her now. 

I hate Hip Hop It's full of liars and actors, these little rappers about as real as they names

"Maybe if you just let me in." Severus said desperately, reaching for her hand, which she dropped into her lap. Severus touched the paper where they had been, glancing at her. "You just need to let me into your world Elizabeth." 

Elizabeth stood up, striding across the lab. She wrenched open the door and then paused in the doorway. 

'Cause all these rappers are putting kids in their graves I hate Hip Hop The whole culture is cancer They'll kill their momma for some clout and a chain

"Believe me, Severus." She whispered softly. "You don't want to be in my world." She let the door close behind her. She didn't slam it, but the finality of the door clicking frustrated Severus and saddened him at the same time. 

Hip Hop hates me, and I hate it too, it's been this way forever I don't move like them, I'll nev-

Severus waved his hand at the radio, which shut off. He picked up the werewolf sheet, scanning the ingredients as a way to get the fight off his mind. Immediately, he saw why vomiting would be a side-effect: she was using 30 ml of Hyacinth extract. 

He looked through her past notes and then wrote a note next to the Hyacinth. 

ᑕOᑌᑎTTEᖇᗩᑕT ᗯITᕼ 20 ᗰᒪ GIᑎGEᖇ

Severus sighed, setting the quill aside and stood up, slowing treading to the door of the lab. He paused then, turning back to the radio, and waved his hand at it once more to turn it back on. 

Welcome to the world, baby girl, I'll paint you pink if that's okay We'll encourage self-destruction through the music that you play. . .

Severus opened the door, leaving the lab to go make dinner.

If It's a Hack and It Works, Is It Really a Hack?

I have a couple servers at home — one running Proxmox VE and one running Proxmox Backup. I use the VM server when I need to spin up a development environment, for running the odd game server, serving files locally, running Home Assistant, etc. I also like to donate spare cycles to Folding@Home. The backup server of course is in case I do something stupid on the VM server.

There's just one problem with that. My second-hand 8-year-old dual-Xeon server runs hot.

It was too much to keep running in my home office. Between the two servers, my desktop, and my work laptop, I was regularly seeing ambient temperatures around 26°C. It was just too warm for comfort.

Last summer I moved my network gear and the two servers into the front coat closet. This was great for me working in my home office, but not so great for my servers. Despite adding a passthrough vent to the closet door and a vent fan to the ceiling, the closet was still consistently in the 26°-30°C range.

The ideal solution would probably be to use an enclosed server rack and run an exhaust vent up from the top. Unfortunately, rack-mount server cases are expensive, enclosed racks are very expensive, and my closet is too small for that anyway.

So I hacked together a solution.

I built a frame out of some cheap 1x2 lumber and wrapped a piece of thin sheet steel around the sides to make a crude plenum. On top, I added a 10x6 register box with a semirigid vent hose coming out of it. This gives me a guide for drawing air out of the servers and guiding it up to the vent fan in the ceiling.

To help things along, I added a 120mm fan inside the register box. But not some whisper-quiet Noctua. This is (if the Amazon listing is to be believed) a 5000 RPM, 210 CFM monster of a fan. It's loud, but moves a lot of air.

Too loud in fact. Its droning could not be silenced by any mere closet door. I had to add a PWM fan speed controller to calm it down. It's a cheap unit from Amazon, but it came with a temperature probe and it has a configurable operating range.

The result? Where previously the entire closet was consistently above 26°C, now it's staying around 23°. There is a difference of 5°C between ambient in the closet and the air inside the exhaust duct, so it is doing its job of redirecting the hot air from the servers.

I call that a successful hack.

Hey I have question, but it needs a little explanation first(not really I just want to talk about this)

The service I use to host my websites are cutting their free hosting option and I have this old computer that I’m going to turn into a server so I’m going to host my websites on that but I need a domain

I have a domain name that I like, it’s a .xyz site, it costs like €2.08 and here is the problem, it’s saying that it’s 88% off and that the original price was like €16, does anyone know if the second year will be that original price or if it will stay at the low price

I’m using name.com because that’s what a lot of articles and such said but I don’t really know so if anyone who has experience with this stuff does know, please tell me, I have no idea what I’m doing :3

[bitsofbitsofbits]

I'm self-hosting my own Link tree alternative. I don't really know why, but I love it :)

Its using a docker called "linkstack" on my Unraid server. Very excited.

[bored-bi]

ok actually i found out that not having my laptop (getting my keyboard replaced) means i forget like half the ports of the things i host. so i made a lil dashboard. its running Homepage [^] and i set it up so it shows all my nodes, virtual machines, and lxc services. screenshot coming later, i have to edit out some stuff due to an nda

[virtualizationhowto]

CoreControl is a great new Home Lab Dashboard #homelab #selfhosting #homeserver #homelabdashboard
