"Jo March becomes god, Massachusetts is consumed by horrors beyond human comprehension, and everyone dies"

Bakker's Second Apocalypse to Little Women was a pretty jarring transition already..

What do you do to winterize the garden? We don't get snow or much frost where I live, so I'm curious how it's done elsewhere.

I designed and built a very simple electric friction drive for my old bicycle, and I'm taking it out for its inaugural test ride this weekend. It's small and simple, fits the elegant utilitatian aesthetic of the bike without altering it, and should make my commute a lot easier. I'm really proud of it.

I just set up Readeck a few weeks ago, and I've been liking it. Very minimalist, utilitarian. One feature I'd like that isn't included is the ability to add specific labels or collections to the sidebar, but that's my only quibble so far.

It has an official browser extension for adding urls to it, but if you can't or don't want to use that, it has a nice api. I use the api to add bookmarks from my phone using a termux-url-opener script, which is as easy as the extension - just hit the "share" button and select termux, and it does the rest.

Navigating around supporting bad actors in the foss community is probably far easier than in the closed, commercial software space, given that all the code, discussion, and money are out in the open.

Also I think the proportion of fascists and bad actors in the foss community is probably lower than elsewhere in the first place, given that the community is based on the free and open sharing of work and knowledge.

First time I've ever seen this, and I love it.

I think my favorite thing in tech is blinkenlights, and my homelab is designed with that in mind. It's pretty, and it's like you can see the bits and bytes flowing around ♥️✨

I compile the kernel on all of my raspberry pis with LEDS_TRIGGER_ACTIVITY enabled, just so I can turn the power light into a cpu blinkenlight, and set the led triggers to some kind of activity on all my laptop and openwrt leds to turn them into blinkenlights too. Blinkenmaxxing.

I wouldn't say it's a big mistake, you've likely still got a few years left on your current drives as-is. And you can replace them with same- or larger-capacity drives one at a time to spread the cost out.

Keep an eye out for retired enterprise ssds on ebay or the like - I got lucky and found mine there for $20 each, with 5 years of uptime but basically nothing written to them so no wearout at all - probably just sat in a server with static data for a full refresh cycle. They've been great.

The actual write cache there - writeback accumulates writes before flushing them in a larger chunk. It doesn't make a huge difference, nor did tweaking zfs cache settings when I tried it a few years ago, but it can help if the guest is doing a constant stream of very small writes.

The datasheet for the Samsung PM893 3.84TB drives say they're warrantied for 7PBW and 2 million hours MTBF (can write 7PB or run for 2 million hours before average drive failure). Quite pricey, but looks like it'll run forever in a home environment.

Good luck!

I delved into exactly this when I was running proxmox on consumer ssds, since they were wearing out so fast.

Proxmox does a ton of logging, and a ton of small updates to places like /etc/pve and /var/lib/pve-cluster as part of cluster communications, and also to /var/lib/rrdcached for the web ui metrics dashboard, etc. All of these small writes go through huge amounts of write amplification via zfs, so a small write to the filesystem ends up being quite a large write to the backing disk itself.

I found that vms running on the same zfs pool didn't have quite the degree of write amplification when their writes were cached - they would accumulate their small writes into one large one at intervals, and amplification on the larger dump would be smaller.

For a while I worked on identifying everywhere these small writes were happening, and backing those directories with hdds instead of ssds, moving /var/log from each vm onto its own disk and moving it onto the same hdd-backed zpool, and my disk wearout issues mostly stopped.

Eventually, though, I found some super cheap retired enterprise ssds on ebay, and moved everything back to the much simpler stock configuration. Back to high sustained ssd writes, but I'm 3 years in and still at only around 2% wearout. They should last until the heat death of the universe.
