Great question (and we are reaching the outside edge of my knowledge here). Something like 3-5% of carbon in plants is taken up from the soil by plant roots. I don't fully understand the mechanism, but the organic carbon percentage is an important competent in the calculation of how much artificial nitrogen a crop is going to need, so I guess it's probably some biochemical process for making the nitrogen available.

The organic carbon percentage is closely watched by farmers and is something of an indication of soil health. ie if your crop rotation is reducing the OC% over time then you probably need to reconsider it. It's one of the reasons burning crop stubbles is a much rarer practice now.

Hay is cut from any sort of cereal plant early in it's lifecycle, specifically before the plant starts concentrating it's energy into the seeds. At this stage the plant stalk is sweeter (even to a human - give it a bite). After flowering, the plant is concentrating it's energy into the seeds. By the time it's fully done this (which takes a number of weeks), there is very little protein in the stalk, and it's far less palatable (or nutritious) to animals. The plant stalk is now essentially 'straw'.

Commercial hay can be mowed from a meadow (in Australia usually ryegrass) in which case it will have all sorts mixed in, or from crops intended for making good hay (in Australia usually oats or wheat). Commercial straw (which has a tiny market) is cut after the grain has been harvested from the top of the plant. In commercial broadacre cropping in poor soil areas (the bulk of Australia's grain areas) it's usually better economics to keep your crop residue including straw since the cost to replace the carbon would be higher that what you'd get for the straw after the cost of harvesting it.

Thanks, I ended up going with Garage, but it has the same issue. I assumed I could just specify some buckets with their keys in the docker-compose or garage.toml, but no - they had to be done through the api or command line.

[–] thirdBreakfast@lemmy.world 3 points 2 weeks ago

This is correct, I already installed the minio cli, but when I came back and read this, I tried it out and yes, once garage is running in the container, you can

alias garage="docker exec -ti <container name> /garage"

so you can do the cli things like garage bucket info test-bucket or whatever. The --help for the garage command is pretty great, which is good since they don't write it up much in the docs.

Thanks. I ended up going with Garage (in Docker), and installed the minio client cli for these tasks.

One I'm writing. I use the host file system (as I have a strong preference for simple) for it's storage, but I'm interested in adding Litestream for replicating the database onto AWS.

 

Has anyone got some experience/advice for choosing between the options? It seems like they are:

My usecase is just to have a local single instance for testing apps against. I prefer to spin stuff up in Docker on the homelab.

Love the effort you've put into this question. You've clearly done some quality research and thinking.

When I asked myself this same question a couple of years ago, I ended up just buying a second hand Synology NAS to use alongside my mini-pc. That would meet your criteria, and avoids the (I'm not sure what magnitude) reliability risk of using disks connected over USB. It's more proprietary than I'd like, but it's battle tested and reliable for me.

Shoutout to Magic Earth, the (weirdly named) iOS app that uses OpenStreeMap data. Works on CarPlay, has reliable routing, and I get a buzz out of updating a changed a speed limit or something on OSM and then seeing the change implemented a few weeks later when I'm driving through there again.

I mostly use starcoder2 with Continue for code autocomplete, the big deepseek coder is a bit slow (I can feel it thinking), but it and the regular llama3 are good for chatbot type programming questions.

I don't really have anything to compare the M1 performance to. I guess the 8GB models output text a little slower than the web versions of the same models, and the 4GB ones about the same. Using ollama in the terminal, there's sometimes a 0.5-2 second pause before it starts outputting. Not with phi3 though - it's surprisingly snappy for the quality of answers.

An M1 MacBook with 16GB cheerfully runs llama3:8b outputting about 5 words a second. A second hand MacBook like that probably costs half to a third of a secondhand RTX3090.

It must suck to be a bargain hunting gamer. First bitcoin, and now AI.

I use the Continue VS Code plugin with Ollama to use a couple of different models (deepseek-coder-v2 & starcoder2) to recreate a local only Github Copilot type experience for coding. This is on an M1 Apple Silicon though. For autocomplete the generation needs to be pretty brisk - I'm not sure how that would go in a VM without a GPU.

 

*What rights do you have to the digital movies, TV shows and music you buy online? That question was on the minds of Telstra TV Box Office customers this month after the company announced it would shut down the service in June. Customers were told that unless they moved over to another service, Fetch, they would no longer be able to access the films and TV shows they had bought. *

 

I've been downloading SSL certificates from my domain provider, using cat to join them together to make the fullchain.pem, uploading them to the server, and myself adding a 90 day calendar reminder. Every time I did this I'd think I should find out about this Certbot thing.

Well, I finally got around to it, and it was one of those jobs which turns out to be so easy you wish you'd done it ages ago.

The install was simple (I'm using nginx/ubuntu).

It scans up your server conf files to see which sites are being served, asks you a couple of questions, obtains the Let's Encrypt certificate for them, installs it, updates your conf files to use it, and sets up a cron job to check if it's time to renew the certificate, which it will also do auto-magically.

I was so pleased with it I made a donation to the EFF for it, then I started to think about how amazingly useful Let's Encrypt is, and gave them one too. It's just a really good time to be in this hobby.

I highly recommend Certbot. If you've been putting this off, or only just hearing about it, make some time for it.

 

I have an ancient domain that for years has been hosted with a company that allowed wildcard email forwarding - so *@example.com was forwarded to my gmail. So over the years, I've just used a new email address for every signup of anything.

Sadly, the company is getting out of hosting, so I need to move the domain somewhere. The commercial email hosting I've seen seen around is all paid for per mailbox.

Is there a commercial email host that would allow a wildcard like that?

I have low desire to run my own email hosting, but perhaps if it's just a bunch of forwards that might be simpler?

 

Such a good feeling cancelling my paid tier on Dropbox this week. I've been 'playing' at self hosting for a few months, and now I'm confident in my infrastructure and processes so I can start turning off some of the cloud things I've been paying for.

Dropbox has gone in favor of Syncthing over Tailscale in a hub and spoke arrangement to a VM at home. The main compromise I've had to make is on the iOS experience.

The next subscriptions I'll be cancelling will be Evernote (I have so loved this over the years, but as they've added 'features' the app experience has degraded to the point where it's no longer reliable to add notes from my phone). I'm currently trying Obsidian for this , but thinking about a simpler web markdown editor for mobile.

After that, all my Wordpress blogs will be coming home to my VPS, I imagine with some sort of static site generator.
