Wow, this is cursed.

monax•1h ago

I think r/unixporn will love it once it gets DOM support :^)

kijin•1h ago

Finally, we can create splash screen animations in pure CSS!

lnenad•1h ago

I think the proper term is blursed.

madduci•1h ago

But why?

monax•1h ago

It's just a silly experiment; the real endgame is to make a bootloader that is customisable using HTML/CSS/JS

magicalhippo•1h ago

Since PDFs can contain JS, presumably that should be the preferred way of modifying your boot loader.

monax•1h ago

Yeah that's the natural next step, I'll work on that next

ThrowawayTestr•37m ago

Why not?

madduci•30m ago

Because this can end very badly. It is a new surface to attack

yjftsjthsd-h•20m ago

Maybe? What's your threat model?

M95D•20m ago

Exactly! It's actually great! More ways to jailbreak stuff.

eqvinox•4m ago

Why is it a new surface? Either you can run UEFI code, or you can't. Attacking the JS interpreter itself is unrealistic IMHO, it's the poorly written JavaScript running on top of this that might open new surfaces of attack. But other UEFI code is mostly written in C or C++, so let's call that a wash?

"Your scientists were so preoccupied with whether or not they could, they didn't stop to think if they should."

Pretty neat, though.

fbnszb•1h ago

Yeah, but your [developers] were so preoccupied with whether or not they could, they didn't stop to think if they should.

redvulps•1h ago

next step is to create a UEFI TUI using react (please don't)

monax•1h ago

OMG we can use ink for that

aruametello•43m ago

you may just have casted a curse on our future motherboards, damn you

my_throwaway23•1h ago

I presume you'll add the network stack next, so that I can use my favourite, most useful packages?

  import isOdd from "https://unpkg.com/is-odd";

monax•57m ago

We are getting isOdd in the bootloader before GTA-IV

spiffyk•39m ago

Wait, when did I time-travel?

monax•33m ago

oops typo

p_l•46m ago

Well, there's a network stack already there, including HTTP and HTTPS on newer firmwares.

catapart•59m ago

Can someone break this down for me? Looks like it's using... C? to load a js interpreter which bootstraps an API around all UEFI features? Do I have that right?

And, if so, does that mean that once the API has been bootstrapped, one could actually write an OS in js? Or are there other abstractions that would need to be migrated first?

monax•56m ago

Depending on your definition of OS, yeah you could do that :)

nxobject•35m ago

Hey, when Apple transitioned from m68k to PowerPC, it took them a hell of a long time to rewrite massive parts of their OS. It's a low bar, though...

DustinBrett•5m ago

OS in JS, ok I am interested now...

bayindirh•58m ago

This project will go places. Like every silly project not intended for production. :)

faxmeyourcode•56m ago

Love this. An example of complete and total dominion over the machine. Great quote here too lol

Smalltalker-80•53m ago

Can't wait for browser support for this... ;-)

monax•48m ago

Soon™

outadoc•50m ago

I love it.

Finally!

lioeters•34m ago

Turning in the widening gyre, the falcon cannot hear the falconer. The center cannot hold.. The old prophesy is coming true.

grougnax•32m ago

Awesome! Everything will be rewritten in JS

GranPC•26m ago

"The Birth and Death of JavaScript" is coming true after all.

rezmason•22m ago

It begins!

Hilarious

pwdisswordfishy•18m ago

Does it manage to support floats? I am not sure if those can be safely used in the UEFI environment. (I recall GRUB’s build of Lua being integer-only, and Linux avoiding the use of floating-point arithmetic in kernel mode, but I don’t remember the reason.)

monax•17m ago

Yeah floats works

rafram•12m ago

This is incredible.

What if it makes me recoil in horror? screams into the void
