08:05:09 <cohcho> Is it possible to load randomx library into memory the same way as it is being done for jit inside randomx (mmap with RWX)?
08:10:51 <cohcho> Of course, it's possible but i've failed with staticaly compiled randomx-tests (received SEGV at free_meme function).
08:11:34 <sech1> Do you mean compile it as .dll/.so and load? Yes.
08:14:58 <cohcho> randomx_elf = open(...).read(); mem_ptr = mmap(...); memcpy(mem_ptr, randomx_elf); init_cache_f = mem_ptr + offset; cache_ptr = init_cache_f(...);
08:15:44 <cohcho> Something like this^
08:15:51 <cohcho> Do you understand my aim?
08:18:13 <cohcho> Since it's difficult to implement general purpose solution for "load shared library into memory from buffer", i've decided to implement "load static executable into memory from buffer in order to call it's functions"
08:21:38 <sech1> You can do this, but you need to do all the work that OS already does for you.
08:21:46 <sech1> You can't simply copy dll/so file into memory
08:25:04 <cohcho> It's easier to load isolated assembly functions but i don't have isolated assembly functions that implement randomx.h
08:26:13 <cohcho> If you think it isn't feasible in reasonable amount of time then skip my question.
08:27:17 <sech1> There is a code to load DLL into memory for Windows, it does everything OS loader does.
08:27:39 <sech1> Maybe something for Linux exists too. Or you can just take it from OS sources.
08:34:49 <tevador> Windows: LoadLibrary, Linux: dlopen
08:35:52 <cohcho> dlopen from buffer*
08:35:56 <cohcho> not file
08:48:09 <tevador> the easiest way is probably to dump the buffer to /tmp and dlopen()
09:11:28 <tevador> 87% of blocks in the last day are voting for v12
09:12:09 <sech1> So most pools have updated by now
12:39:25 <tevador> https://github.com/tevador/randomx-sniffer
12:39:30 <tevador> feel free to test
12:39:35 <tevador> Windows only
12:43:57 <sech1> "CC0"?
12:46:01 <tevador> public domain
12:46:41 <tevador> https://creativecommons.org/publicdomain/zero/1.0/
12:47:20 <sech1> To be most effective, this sniffer should automatically ask for elevated privileges if it's not run as administrator
12:47:44 <sech1> Hidden miners can disable access to their threads
12:49:08 <tevador> run it in elevated cmd.exe
12:49:28 <tevador> it's only meant as PoC, not for actual use
12:51:50 <sech1> I guess AV software can add this heuristic quickly
12:51:59 <sech1> Maybe we should even contact AV companies
12:52:37 <tevador> yeah I've been thinking about that
12:52:45 <sech1> The better heuristic would be to probe suspicious process twice and check if their rounding modes change
12:53:08 <sech1> and if different threads have different rounding modes
12:53:47 <tevador> yeah, there are better heuristics, but the vast majority of processes only use the default mode
12:57:56 <gingeropolous> nice
13:00:10 <Inge-> I wonder how 3970x and 3990x will be to cool.
13:00:27 <Inge-> 3900x is pretty hard to cool with 280mm AIO as it is
13:02:05 <gingeropolous> moneros gonna burn the world down
13:02:47 <rottensox> climate change!!!
13:02:52 <nioc> 360mm is recommended for 3970x
13:03:03 <nioc> wen 3990x release
13:03:17 <rottensox> soon^(tm(
13:03:20 <rottensox> soon^(tm)
13:03:28 <nioc> I have a NH-14US for my 3900x
13:04:42 <nioc> 75C at 100% cpu
13:05:55 <nioc> stock
13:14:16 <rottensox> you're burning that little guy.
13:14:22 <rottensox> y tho.
13:18:12 <Inge-> nioc: how much more cooling do you get from 360mm ws 280mm?
13:19:43 <Inge-> according to a simple back-of-envelope calculation of surface areas (120*120*3 vs 14*14*2), the 360mm radiator is 10% larger
13:20:46 <nioc> that was a recommendation from a YT channel tester
13:21:31 <Inge-> "stock" is extremely misleading - as mine would then pump 1.3 - 1.45v through the CPU ...
13:22:33 <nioc> yeah I just started running it and haven't changed anything
13:23:00 <nioc> can't even figure out how to set the # of threads in xmrig lol
13:23:11 <nioc> I can for wowrx
13:23:21 <nioc> or rx
13:23:45 <nioc> but cn/r isn't listed
13:26:34 <gingeropolous> glad your mining nioc !
13:28:30 <nioc> gingeropolous: thx lol,  my roi is the heat death of the universe
13:28:47 <gingeropolous> aye, me too
13:48:30 <gingeropolous> whats the power consumption on the polaris compared to cnr?
13:48:59 <gingeropolous> im debating if I should switchover some miners remotely....
13:51:16 <tevador> https://github.com/SChernykh/RandomX_OpenCL
13:51:22 <tevador> not sure how old those numbers are
13:53:29 <sech1> OpenCL code haven't changed much since summer
13:53:56 <sech1> You can always set power limit for your GPUs, I don't see a problem here.
13:55:28 <gingeropolous> im using hiveos. i wonder if its even doable. looks like they're slacking when it comes to randomx. which makes sense. its a gpu rig thing
13:56:58 <sech1> I'll be mining with my Vega 64 in the first day or two by the way
13:57:09 <sech1> Electricity is included in rent, so why not?
13:58:10 <sech1> and it'll make a nice space heater in this cold weather
13:58:20 <tevador> it's best keep mining and see what happens
13:58:57 <gingeropolous> yeah my vegas are managed by mmpos
14:28:18 <needmonero90> https://thecryptogarden.blogspot.com/2019/11/crowdmine-it-first-website-that-allows.html
14:28:22 <needmonero90> Is this a scam?
14:28:28 <needmonero90> I thought browser mining wasn't a thing
14:29:32 <selsta> maybe not updated for randomx?
14:29:52 <needmonero90> Five year old account with zero karma posted it on /r/monero
14:29:58 <needmonero90> It got hit by our karma filter
14:30:08 <needmonero90> And I'm just feeling very strange about it
14:30:14 <needmonero90> Can someone look into this for me? :)
14:30:31 <needmonero90> I want to know if we should approve, or if it's sketchy
14:30:38 <tevador> it's probably just cryptonight, so will be on the wrong chain soon
14:30:48 <needmonero90> This is new tho
14:30:53 <needmonero90> I've never seen the site before
14:31:04 * needmonero90 wonders if it's a virus or possibly randomx
14:31:17 <needmonero90> Releasing a day before the fork makes me hesitant to assume it's CN
14:31:45 <selsta> I’d ask for more info on it first
14:31:47 <selsta> before accepting
14:32:31 <needmonero90> I think it is CN
14:32:46 <needmonero90> The leaderboard on the site says they distributed the tokens for september
14:33:04 * needmonero90 is just confused at this point 
14:35:56 <sech1> Web mining for RandomX is in the realm of "fairy tales" now
14:37:24 <tevador> https://paste.debian.net/hidden/63d85ed5/
14:37:32 <tevador> doesn't support randomx
14:38:21 <moneromooo> That website looks like what I'd love to see using the pay-for-service thing and primo.
15:43:39 <needmonero90> Thank you tevador
15:45:36 <tevador> btw I sent an email to avast, microsoft, eset, avira, kaspersky and trendmicro
15:46:41 <tevador> and symantec*
15:52:15 <sech1> I think they all just add every new xmrig release to their bases automatically and call it a day. Don't expect much.
15:53:07 <sech1> There's also Sophos: https://en.wikipedia.org/wiki/Sophos
15:53:27 <tevador> that's very easy to circumvent
15:53:41 <tevador> but also most hackers are lazy, so it may just be enough
15:54:04 <cohcho> What does it mean to add xmrig release into antivirus?
15:54:13 <cohcho> binary hash sum?
15:54:16 <sech1> Freshly compiled xmrig also triggers AV, so they have some generic signature for it
15:54:51 <tevador> probably machine learning
15:55:40 <sech1> nah, probably they search for AES tables + Groestl/Blake/JH/Skein code
15:55:47 <cohcho> At least two instances of xmrig are required in order to know the price and quality of their detection.
15:55:52 <sech1> if everything is there => trigger alarm
15:56:30 <cohcho> two instances that maps to {detected, undetected}
15:57:03 <tevador> so if you strip down xmrig to just randomx, it probably won't be detected
15:59:23 <sech1> yes
15:59:35 <sech1> I actually tested it
15:59:43 <sech1> Pure RandomX doesn't trigger AV... yet...
15:59:50 <sech1> But it'll change next week, lol
16:38:55 <sech1> Out of all major pools, xmrpool.eu, minergate.com, c3pool.com, dwarfpool.com are still not updated
16:39:48 <sech1> These 4 pools are 9 MH/s combined
16:41:43 <moneromooo> Feel free not to help minergate and dwarfpool if they request help to do so.
16:43:15 <moneromooo> Hmm. Actually... Even if they're scammers, it still adds some degree of decentralization as a whole... Hmm. Hrm. Interesting conendrum...
16:55:38 <sech1> Personally I don't want to have minergate around
16:56:39 <sech1> I'm sure they'll update. More than 95% of blocks are v11.12 already, so not a big deal.
19:31:05 <needmonero90> https://www.reddit.com/r/Monero/comments/e3d5qx/using_your_cpu_to_fund_projects_mining_xmr/f92odr1
19:31:30 <needmonero90> Tevador pls knock some sense into them
19:32:04 * needmonero90 sighs
19:32:16 <needmonero90> Do I let it through? Is mining altcoins and converting to Monero Monero enough for the sub?
19:34:55 <needmonero90> I suspect that they're referring to minergate, it's a multiminer right?
19:35:14 <sech1> It might be MoneroOcean
19:35:34 <sech1> they can use it to do exactly that
19:36:25 <needmonero90> Basically. I need to know if this is legit and whether to approve. But I'm not deep enough into the mining scene to know, other than to see red flags
19:37:45 <sech1> "in fact, they mine altcoins and turn them into XMR on the fly" sound like MoneroOcean to me
19:38:09 <sech1> They need to describe better where exactly they mine, what algorithms and who converts it to XMR for them
20:25:05 <tevador> yeah, if they are mining some CN shitcoins on MoneroOcean and converting to XMR, that could work
20:25:12 <tevador> or it could be a scam, who knows
20:25:57 <tevador> even if it's legit, it's likely their rewards will gradually decrease to 0 as CN is phased out
21:08:14 <needmonero90> https://www.reddit.com/r/Monero/comments/e3bjg6/randomx_as_well_as_multiple_privacy_improvements/f93k2qr
21:08:19 <needmonero90> Pls confirm
22:26:56 <hyc> yes
22:27:00 <hyc> all the girls and boys
22:39:04 <tevador> so at least one pool is shutting down: https://help.poolin.com/hc/en-us/articles/360036959332-Announcement-on-Suspension-of-Monero-XMR-Mining-Pool
