I'm vaguely in the "market" for a new computer algebra system (Mathematica, Maple, Sage, SymPy, etc etc) and I am curious what experience you all might have with these types of programs. In the past I've used Mathematica, and once you get over the odd aspects of the Language (and hefty license fee), it is a pretty great piece of software. Nonetheless, now that my old student license has expired and I would have to buy a new one (though through my school I can get it at a steep discount) I'm looking at some alternatives. Sage seems particularly appealing since it is open source and apparently well documented, and of course SymPy is powerful although that as stand-alone as these other choices.

There are tons of other options as well, with a wide range of functionality (it really is amazing how much these things can do). My main use cases with these types of things are either: a) algebraic manipulation, b) linear algebra, c) visualization. For these three it does really seem that Mathematica is at the forefront, but I'm all ears for other opinions.

I'm curious, if you have used any or all of these in the past, what were you using them for and what is your opinion?

Late 90s alt-rockers Eve 6 return with their first new music in almost nine years. The extremely catchy hooks the band has been known for are back. Lyricist/sing Max Collins has also with a return to form on his excellent lyrics with lines like "wayward jehova/ask for a corona/ in the ambulance. The growth here seems to be a bit of the electronica influence from Collins' side project, Fitness, and his vocals, which sound more like Scott Weiland than the teen we know for singing the heart in a blender song.

A little more laid back than some of eve 6's prior work, we'll see where the rest of the EP goes when it's released this summer.

What have you been listening to this week? You don't need to do a 6000 word review if you don't want to, but please write something! If you've just picked up some music, please update on that as well, we'd love to see your hauls :)

Feel free to give recs or discuss anything about each others' listening habits.

To elaborate more, the realization that LGBT rights, marriage, transitioning, etc are more than just human rights, they're your rights and whenever homophobes succeed in stopping LGBT rights, your rights are stripped away by people who hate you.

Also, If you're bisexual, did/do you ever consider just tagging along as if you were straight because you could and would rather not deal with homophobes? (Assuming this question makes sense)

As part of a weekly series, these topics are a place for users to casually discuss the things they did — or didn't do — during their week. Did you accomplish any goals? Suffer a failure? Do nothing at all? Tell us about it!

I'd like to gauge interest in a writing group. The quality of expression I find at Tildes and the nature of some of the Timasomo projects prompt me to wonder if maybe there aren't enough regularly-writing members to form a circle for critique and support. I have some experience teaching, but never have run a group. I'm a committed generalist--I don't think I would want to limit it to a particular form or genre.

Anyone interested? Have you taken part in one before / belong to one now?

This topic is part of a series. It is meant to be a place for users to discuss creative projects they have been working on.

Projects can be personal, professional, physical, digital, or even just ideas.

If you have any creative projects that you have been working on or want to eventually work on, this is a place for discussing those.

What have you been doing lately for your own fitness? Try out any new programs or exercises? Have any questions for others about your training? Want to vent about poor behavior in the gym? Started a new diet or have a new recipe you want to share? Anything else health and wellness related?

I recently fixed my old wristwatch when I realized the need to know time is one of the causes for my smartphone addiction. It is nice to know the time from a device without WhatsApp, a web browser, or notifications.

Here it is, nothing fancy but extremely durable, about 15 years old: https://imgur.com/gallery/daDVelR

I’m looking into getting a Casio digital wristwatch with a simple alarm function and a light to see it in the dark. Again, nothing fancy. Just a piece of reliable, single purpose hardware. I love things like that.

They also look really nice.

Do you have and enjoy “dumb watches”? Why? Let’s talk about that :)
