Anyway, how went your holidays?

Sure, I don't personally celebrate Christmas, and loathe Christianity in general, but was being nice.

01:16

dpb

i don't celebrate christmas and the reason is because I fear the God of the Bible.

01:16

I fear no god, nor death; I wouldn't mind worshipping a god I find repulsive and evil, but I'm certainly not going to worship a repulsive and evil god I don't even believe exists.

01:19

Well, trying to be nice resulted in something not nice at all.

Yes, just ignore the earlier feedbot entry.

01:30

For that matter, ignore this feedbot entry for the next fifteen hours or so.

"Lurkers are asked to introduce themselves at first join" i have a laptop with cr50 chip, looking for anything to make it more like, and i got here, somehow

14:12

Welcome macc24

14:13

hi shinohai

14:13

asciilifeform may be back in a bit, I assume you read article on loperos re: cr50 laptop ?

14:14

yeah

14:16

neat!

14:17

i have a different device, lelnono chromebook duet, with faster soc and much more broken linux

14:20

ouch. I haven't experimented with cr50 personally yet so unfortunately can't help :/

~ 22 minutes ~

14:42

trinque chuckles mightily at "lelnono"

14:45

macc24: there's been afaik no major discoveries, by anyone, re: subj, since my orig. overview of cr50.

↖

14:45

asciilifeform: any way to dump its firmware?

14:46

macc24: not, afaik, as such. the update bins are public tho (as is, strangely, the source, last i knew)

14:46

so if you 1) allow yours to update 2) disasm that bin -- you get effectively 'dump of firmware'

14:47

see e.g. my disasm of pertinent routines re lock-in.

14:48

^ did this because the src did not contain, unsurprisingly, current pubkeys used in deployed machines

14:49

macc24: ftr i abandoned all work w/ that machine. no one knows when it will go out of print (these usually live for coupla yrs) ; and even if i had found a 0day in cr50, vendor would simply patch it as soon as published.

14:50

there can be no permanent workaround against a user-hostile iron vendor.

14:50

ack

14:50

the only pill is -- to find another, that isn't. presently no one is making non-boobytrapped portable comps.

14:51

(or, for that matter, desktops..)

14:51

there are a couple of firms which ~fraudulently~ pretend to. i will not bother to list.

14:51

my guess is that starting with sbc and building that into a laptop might not be that bad

14:52

macc24: even w/ sbc. if it's an 'arm', it has 'trustzone'.

14:52

which is pretty much same thing as e.g. 'intel ME', 'amd PSP', google's 'cr50', etc

14:53

they don't really lock it

14:53

afaik

14:53

if you can't zero out the fw for it, and the chip won't boot w/out it -- is locked enuff, imho

14:53

it's a fritz.

https://github.com/ARM-software/arm-trusted-firmware this runs in trustzone?

14:54

if uboot contains no blobs, i have libre boot firmware running on my odroid go advance

14:55

aside from rk3326's bootrom

14:58

the whole device is pretty simple, 2 ram chips, spi nor flash chip, rk3326, rk817 pmic, ncp372 and wifi chip on one revision that's easy to remove

Hello, macc24.

15:23

hey verisimilitude

15:24

So, have a website, macc24; most people here do.

15:25

i have no website, might have in future

15:25

Alright.

15:25

although i have a domain, prostok.at

15:26

Is it used for anything?

15:26

nah

I hoped against hope it was a mobile meth lab explosion, but alas no life imitating art here.

17:27

Why hope for that, shinohai?

verisimilitude: Breaking Bad joke.

Now I'm hearing fools claim it was actually a missile strick, which of course means the US would need to go to war with whatever power is both weak enough and disliked by the cabal ruling society.
