this guy stops ramping up on weekends and during the night European time
-
gethh
so typical 8/5 day job
-
sech1
he probably has to solve a lot of captchas to add "workers" :D
-
sech1
These fire hydrants, semaphores, bikes and buses will haunt him forever...
-
gethh
lol

Inge-
new rPi 4 w/8GB ram and 64 bit
-
asymptotically
i thought all but the pi 1 were 64 bit, and they just never bothered to ship a 64 bit kernel or userland for it
-
Inge-
that might well be true
-
Inge-
sech1: I lose a part of my humanity every time I fail a "confirm you are not a robot" captcha
-
Inge-
asymptotically: "Not to be left out, today we’ve released an early beta of our own 64-bit operating system image. This contains the same set of applications and the same desktop environment that you’ll find in our regular 32-bit image, but built against the Debian arm64 port."
-
hyc
pi3 was the first 64bit, but they have always shipped 32bit OS
-
hyc
to retain compat with pi2 and pi1
-
Inge-
world moves on
-
hyc
it's about time

When do you think is this guy going to stop?
-
selsta
does the low hashrate per worker speak against ASICs?
-
selsta
(not that I think it is an ASIC anyway)
-
xmrpow
I think that could be easily faked.
-
Inge-
when is that hashrate running?
-
Inge-
during workhours, or outside workhours?
-
xmrpow
always and it is constantly growing
-
xmrpow
-
xmrpow
even the workers shown as offline are just some weak machines which can not submit shares that often
-
Inge-
not sure what I'm seeing. 1700H/s?
-
xmrpow
?
-
xmrpow
sry wrong link
-
xmrpow
that was just one worker
-
xmrpow
-
Inge-
60K workers
-
xmrpow
yep
-
Inge-
all hashrates seem to be multiples of 840 h/s
-
xmrpow
hmm you are right...
-
xmrpow
good point
-
xmrpow
Maybe this guy faked the workers?
-
Inge-
There is a clue there, just not sure what it is.
-
xmrpow
Why does this guy even bother pointing out each single miner. That does not make much sense.
-
sech1
multiples of 840 h/s is just how nanopool counts shares
-
sech1
just select individual worker and see hashrate graphs
-
selsta
I have to add
developer.apple.com/documentation/b…_disable-executable-page-protection to get randomx working with hardened runtime on macOS, does anyone know why?
-
xmrpow
sech1: ok
-
hyc
selsta: because randomx needs to create code in writable RAM and execute it
-
hyc
although we also have a mode to make the pages read-only again before trying to execute, that's not the default
-
hyc
and resetting page protections is a perf hit
-
selsta
-
selsta
but thanks, we can use `com.apple.security.cs.disable-executable-page-protection` without problems
-
hyc
in monerod you could set env MONERO_RANDOMX_UMASK 16
-
hyc
16 = RANDOMX_FLAG_SECURE
-
hyc
which will toggle the pages to readonly before executing
-
selsta
with a perf hit?
-
hyc
yes
-
selsta
can’t get it to work with the env var, but yea it’s not a problem anyway
-
hyc
ok
-
hyc
I'm surprised allow_unsigned_executable_memory wasn't enough
-
selsta
allow_unsigned_executable_memory is required so that monerod starts without crashing
-
selsta
but then when mining it says `Error: Mining did not start -- BUSY`
-
hyc
strange
-
selsta
do you think there is value in this runtime hardening?
-
hyc
for the especially paranoid, yes
-
hyc
I think the allow_unsigned... flag only works if we use MAP_JIT on our mmap call
-
hyc
which we currently don't
-
selsta
-
hyc
so if you can play with patching that in randomx/src/virtual_memory.cpp
-
selsta
but that did not help, most likely because we don’t use MAP_JIT
-
hyc
might be worth testing again
-
hyc
here's a relevant patch
herumi/xbyak #84/files
-
selsta
will try
-
hyc
only the mmap in allocMemoryPages() needs this flag
-
hyc
allocLargePagesMemory can be left unchanged
-
selsta
hmm it’s a bit difficult to test
-
selsta
looks like it only likes code signing only likes static gitian binaries
-
selsta
don’t have static bin setup here... will test later with gitian
-
geonic
hyc did you set the threshold to 64gb after we spoke? I solo mined another block.
-
geonic
-
geonic
lol
-
tevador
geonic: what hashrate?
-
geonic
4000 H/s
-
tevador
cool, you won the lottery - twice
-
geonic
this is how addictions start
-
tevador
post on /r/MoneroMining, it may motivate more solo miners to join
-
geonic
I just spammed the main sub
-
geonic
will post there as well
-
niocbrrrrrr
geonic: couldn't happen to a nicer guy
-
geonic
thanks nioc
-
hyc
I will take my 10% commission now ;)

xmrpow
69 Mhs
-
geonic
haha

gethh
thats around 0.6MW using the most efficient cpu available
-

$750 per day at 5 cents per kWh
-
jwinterm
720 even
-
xmrpow
It would be like 5307 ryzen9. That would be round about 2,6 million for equipment. With current diff it would take this guy 884 days. I dont think that is worth the risk for an investor.
-
xmrpow
* would take him 884 days for roi
-
selsta
hyc: did not get it working with MAP_JIT
-
selsta
-
selsta
hmm runtime hardening randomx benchmark might be easier to test...
-
selsta
lol I’m dumb :)))
-
selsta
com.apple.security.cs.allow-unsigned-executable-memory is enough, even without MAP_JIT
-
selsta
my daemon was not synced......
-
selsta
hyc: so it appears adding MAP_JIT means it is possible to use com.apple.security.cs.allow-jit instead of com.apple.security.cs.allow-unsigned-executable-memory
-
selsta
which looks like an improvement
