(ironically) oyster meal 💀

off for a few days and then this honker popped up. So next round I’m doing only 10-15 minutes of fan per day. Maybe even less Good to know! I have some blocks almost fully colonized. I wonder if putting them to fruit in an open room (my living room) is already too much air flow for them.

So, how is the situation with the white spots? Did they end up being benign?

[–] Max@mander.xyz 1 points 2 years ago

Thanks! In the end I converged to setting a WireGuard tunnel and using the iptables to route the connections to port 80 and 443. I did look into ssh tunnel, and the reason I chose not to use that is because from what I could gather (from what some people say, I don't know enough myself to assess this) WireGuard tunnels are more optimized for performance than the ssh tunnel.

In that case, you’re better off just using the VPS machine as port forwarding port 443 to your home machine’s wireguard IP address and handle the SSL/TLS termination on the home machine.

This is what I would like to do! I was trying to handle the SSL termination 'automatically' by simply forwarding the connections to 443 of my machine's wireguard IP using nginx, but I did not manage to get it to work. That's when I found that I need to use something like 'stunnel' to handle the SSL termination. But I think that you may be suggesting an even simpler method of using port-forwarding instead of the reverse proxy. I am not sure how to achieve that, I will look into it using these terms.

ssh tunnels

There are so many concepts to learn about! But if the SSH tunnel improves the the available useful bandwidth compared nginx/wireguard, it might be worth looking into it too. Thanks!

Thanks a lot! This is kind of the configuration that I have converged to, with nginx and WireGuard. The last thing I need to set up correctly is for the SSL handshake to occur between the client and my home server, and not between the client and the internet-facing VPS, such that the information remains encrypted and unreadable to the VPS. The two strategies that I have seen can do this is SNI routing with nginx or to use stunnel. I still have not been able to set up either!

Wow! What is the substrate? Do you have any special tips for making them grow this large?

[–] Max@mander.xyz 1 points 2 years ago

That's the next topic then. Thank you

Oh, cool! I have managed to do it with the Wireguard tunnel! I set up a tunnel and use the nginx proxy_pass to redirect through the tunnel. It is pretty nifty that I don't even need to port-forward!

My next step is: in my current configuration, the SSL handshake occurs between the VPS and connecting client. So the VPS has access to everything that goes through... I need to figure out how to hand-shake through the tunnel such that the VPS does not get the SSL keys.

Thanks a lot for your suggestion!

Thanks! Wireguard was suggested as a VPN, and I am currently playing with that.

From what I have learned today, I think that Wireguard Tunnel is what I want!

First I was able to use nginx as a reverse proxy to route the information from my home network through the VPS. But with this approach the client would do the SSL handshake with the VPS, and then the VPS fetches information from my home network via HTTP. Since there is no encryption layer between my VPS and my home network, I suppose that the flow of information between my home server and the VPS is insecure.

Then, I need to establish some form of encrypted connection between my home server and the VPS... And that is where the Wireguard Tunnel comes in! This tunnel allows me to transfer the information with encryption.

I am still reading and setting it up, but yeah, I'm liking this, thanks!

 

I have a nextcloud instance being hosted from my home network. The URL associated with it points directly at my home's IP. I don't want to host the instance on a VPS because disk space is expensive. So, instead, I want to point the URL at the VPS, and then somehow route the connection to my home's nextcloud instance without leaking my home's ip.

How might I go about doing this? Can this be achieved with nginx?

EDIT: Actually, not leaking my home's IP is not essential. It is acceptable if it is possible to determine the IP with some effort. What I really want is to be able to host multiple websites with my single home IP without those websites being obviously connected, and to avoid automatic bots constantly looking for vulnerabilities in my home network.

 

I am trying to grow Oakmoss lichen (Evernia prunastri) at home, which is a highly valued lichen in the perfume industry due to its woody and sweet odor.

Lichens consists of an association between at least a fungus and a green algal partner - but often other organisms like yeasts and cyanobacteria are also present in the association.

I tore some oakmoss to expose the white tissue underneath, and you can see the fungal hyphae and the algae:

To culture a fungus one usually begins by isolating it away from the many contaminants that are naturally present on the fungus. Lichens are more problematic because in their lichenized form they grow too slowly to succesfully out-pace contaminants. The organisms that they are made of grow faster when they are not lichenized, but they have different methods of isolation. The trick to grow them is to isolate the fungus (mycobiont) and the alga (photobiont) separately and then try to bring them together in a process called "resynthesis".

I am trying to do this process at home, starting from a small piece of lichen that I collected from the bark of a tree. This is what grew out of the tissue sample when it first went into the agar, showing lots of contaminants fighting for the nutrients in the dish:

And this is the growth after the first transfer:

In parallel, I am trying to isolate the algal partner, which is a Trebouxia. One method is to place the tissue in agar plates with no nutrients and expose the plate to the sun. The other method is to place the tissue in a solution of orchid fertilizer in water and leave it by the window.

The cells of the alga are easily released into the water when the lichen is crushed. I confirmed that under the microscope. This is a photo of the released Trebouxia cells under the microscope:

The plate in the image associated with this post is a plate of the Evernia mycobiont that had bacterial contamination in it. Rather than throwing it away, I decided to crush some lichenized tissue in water and pour in on top of the lichen to check whether that is enough to achieve lichenization.

Just wanted to share some of my experiments! Any input on how to achieve the resynthesis would be greatly appreciated ;-)
