Given it's about organization, the word 整理 makes more sense than 生理. Both are read "seiri" but context makes it obvious that it isn't 生理. The definition of the word is included in the article and the logo of the application.
Reading the article: I don't think this will replace beets.io for library management, personally.
Note: I did not make this, I am posting this because I think it looks cool.
Also, I was trying to figure out what libraries they used to make it but was not able to figure it out :X
Probably not shellinabox, but this is one tool you may be interested in, if you want to provide shell interface to CLI programs on the web. https://github.com/shellinabox/shellinabox
PICO-8 is totally awesome. I've built a few simple games, and have been encouraging my daughter to make games. She can't program (yet!) but she can play with the sprite editor and sound editor :)
The limitations really make it easy to not worry and just make a dang game! For those of you worrying about cart size limits: if your game is too big for one cart, make it a two-parter :P
Also, apparently you can load data from another cart while your game is running so you could just chain a whole bunch of them together.
Two things I am really excited for are support on Pi-style hardware, and mobile support for the web player.
My understanding is that with PICO-8 you can export to HTML5. If this is the case, (I haven't used this myself.. Yet.) why would you need direct support for mobile and Pi's? Couldn't you just change the dimensions of the app to fit mobile devices, and take advantage of the HTML5 support while on a Pi?
