Are there free alternatives to ChemDraw/ChemSketch that work well? I cannot afford that licence fee. #askfedi #chemistry

I'm still considering setting up a single user instance. I'm trying to go with a low-power Raspberry Pi 2B, which is up to date with Debian. I know nothing about C - it seems like a good option for that hardware, but am I in for a load of issues going in blind? My other option is gotosocial, but I would need to do more work to get a database set up and deal with media storage. #askfedi

#chemistry folk of the fediverse, does anyone have tips for cleaning well plates efficiently? We do a lot of microchemistry in this unit and cleaning these well plates is killing me. #askfedi

After a couple failures, I got a #cyanotype print to work. This is for #chemistry students next week to fuse art with chemical reactions. I was lazy and printed this on transparency paper. Next week, we'll take a walk and gather things to use. They'll also have the option of drawing on glass to create a negative.

Some bluebirds from last night. I haven't painted in a very long time, so I'm happy with these (except for that beak on the right). #watercolor #mastoart

I think I dug a hole for myself in the #webdev class again. I offered groups a chance to build what they wanted using any skills/tools we've used so far this year. One group was to build a chat app (websockets), so they need a server. Two other groups want to make, essentially, CRUD apps, so I need to write up some DB schemas for them. I'm wondering if it'd be better to teach them some Node and they write up their _own_ server-side code.

There's a project I did years ago at an old employer that is tied to Sentry. I forgot to turn it off before I left and I'm not even sure it's still being used. If I delete my Sentry account (I don't need it at all anymore) will that cause issues on the client if they do happen to still be using it?

Do any #chemistry teachers have an equilibrium constant lab that does _not_ use iron and thiocyanate? I've been looking and looking, but I cannot find any other examples of lab procedures. #teaching #askfedi

We got notice of a case of Scarlet Fever in my older daughter's school yesterday. Seems like all the old diseases are making a comeback this year.

Yesterday's xkcd made me angry-laugh.
