Also, can't wait for sodium sulfur batteries to really take off!

Sodium Ion Batteries are, apparently, now in production. As in, this isn't theoretical. Customers are purchasing and using them now.

How Na-Ion batteries differ from Li-Ion batteries:

First, Na is very similar to Li but heavier so in general they operate the same way. But, obviously, there's no Li in a Na-Ion battery. But apparently neither is there any cobalt or copper or graphite.

No Li, Co, and no Cu means Na-Ion batteries are much less costly in terms of materials but also in terms of labor and environmental hazards.

But Na is heavier than Li so what about energy density? Well, there's a claim here that these Na-Ion batteries have comparable energy density to Li-Ion batteries. Which would mean there must be a mass-savings in some of the other constituents of the battery, right?

Well, whatever. It's something I'll be keeping an eye on. If it all works out this could be a very good thing indeed.

Apologies for the fundamental question, but I can't seem to find what I'm looking for online.

I'm trying to help test the new Fedilab app, and one error I've been having is that I'm unable to upload photos from the app. The developer said that my instance does not return supported MIME types. An update was provided that prevented it from crashing from not detecting the MIME type, but the draft window just closes, so I'd like to try to fix it on my server.

Is there a way to fix this on my server easily, and where is the MIME type file located? Which mime types should I enable?

Thanks!

It's true, Mastodon is but one service in a constellation of applications all communicating together via the ActivityPub protocol. There are services that simulate Reddit, music and video streaming (spotify/youtube), blogging, etc., etc. There is a wide world to the Fediverse, as I'm posting from Friendica, another social network service. :)

After Musk's Twitter Deal, Users Rush to Mastodon | Make Tech Easier


This news caused one of Mastodon’s main servers, mastodon.social to slow down. The site is very similar to Twitter in the way messages appear; however, Mastodon is constructed of multiple servers that work independently of each other but can still interact with each other. The system has been compared to the way multiple email servers interact.

Thought I'd write an #introduction for all those #newhere from the Musk exodus:

I'm an analytical chemist. I've hosted my own #Friendica node (instance) at my home since 2018, shortly after the Cambridge Analytica scandal. From there, I got bit by the #selfhosting bug and am now hosting my own #opensource replacements for many FAANG services.

Welcome all to the #fediverse ! If you are thinking about self-hosting and have questions, would be happy to help as able!

Cool, any chance you might be able to look over the logs later? I've made a couple posts that weren't received by folks expecting to get them, so I'm not sure the issue is that they aren't following. I'm also having lots of trouble federating with a remote profile, social.lightsout.games/profile… I don't appear as a follower on that instance, but I've followed/unfollowed the account several times with no change. Anyway, no rush, I'm just glad to have found someone with access to logs on this end. :)

I'm also curious about how some of the posts appear to me. I'm a screen reader user, and am not sure if this is an accessibility issue or something else. I can see my own posts on the forum, but they appear as just the post title and the forum tag. I can't see the content locally, though I can see it when viewing the forum instance. I'm wondering if there's some sort of inaccessible "View more" control to expand longer posts, but there's also a lot in the interface that I'm still getting to grips with.

Thanks.

@JB Carroll @Lights Out Games As we were discussing on XMPP/Matrix, this might be caused by not being able to deliver AP posts to any other instance (i.e., no posts to subscribers, no forum posts). The log contained such lines: worker [INFO]: Transmit to https://nerdica.net/inbox/xyz returned 202 ... APDelivery ... HTTPSignature.php line 309 function "transmit" HTTP 202 means "Accepted", and Friendica bails out on a request on signature failures. The same happened with another user (Clay) some days ago. This is a YUnoHost install if it matters.

@Steven Brady I mainly use them for when the install would be a bit too over my head otherwise! Haha. Matrix was one of those. Just didn't have a lot of experience setting virtual environments. Also with docker everything is stored in the same folder (config, data, etc.), so it makes it a bit easier to migrate.

I generally can wrap my head around docker-compose a lot easier than normal docker. You mostly just set everything up in the compose file as YAML, then add a few links in the config to external config files (matrix needed to do this). Still had to fight with nginx and Postgres in docker-compose for a bit, but nice to have it all up and running together.
