gollark: - All this useless random junk can autoupdate (this is probably a backdoor)!- EZCopy allows you to easily install potatOS on another device, just by sticking it in the disk drive of any potatOS device!- fs.load and fs.dump - probably helpful somehow.- Blocks bad programs (like the "Webicity" browser).- Fully-featured process manager.- Can run in "hidden mode" where it's at least not obvious at a glance that potatOS is installed.- Convenient, simple uninstall with the "uninstall" command.- Turns on any networked potatOS computers!- Edits connected signs to use as ad displays.- A recycle bin.- An exorcise command, which is like delete but better.- Support for a wide variety of Lorem Ipsum.
gollark: Best viewed in Internet Explorer 6.00000000000004 running on a Difference Engine emulated under MacOS 7 on a Pentium 3. Features:- Fortunes/Dwarf Fortress output/Chuck Norris jokes on boot (wait, IS this a feature?)- (other) viruses (how do you get them in the first place? running random files like this?) cannot do anything particularly awful to your computer - uninterceptable (except by crashing the keyboard shortcut daemon, I guess) keyboard shortcuts allow easy wiping of the non-potatOS data so you can get back to whatever nonsense you do fast- Skynet (rednet-ish stuff over websocket to my server) and Lolcrypt (encoding data as lols and punctuation) built in for easy access!- Convenient OS-y APIs - add keyboard shortcuts, spawn background processes & do "multithreading"-ish stuff.- Great features for other idio- OS designers, like passwords and fake loading (est potatOS.stupidity.loading [time], est potatOS.stupidity.password [password]).- Digits of Tau available via a convenient command ("tau")- Potatoplex and Loading built in ("potatoplex"/"loading") (potatoplex has many undocumented options)!- Stack traces (yes, I did steal them from MBS)- Backdoors- er, remote debugging access (it's secured, via ECC signing on disks and websocket-only access requiring a key for the other one)
gollark: <@111608748027445248> ALL OF THEM.
gollark: See, thing is, most foolish people who install it cannot write those ten lines or even just [SEARCH ENGINE AS VERB] it.
gollark: Maybe with some sort of extension of ARC we could also get a sort of better, opt in version of OC holograms.
