<jbjnr> hkaiser: what's goin on with IRC and blocking users. Is this spam a problem that is going to continue?
<hkaiser> jbjnr: no idea how long this spam will be a problem
<hkaiser> jbjnr: I set the channel to +m (i.e. users have to be registered or need to be invited)
<hkaiser> let's hope the spam will subside at some point
<jbjnr> heller: yup. that memory order issue - might be why we have clang problems on power. though we tried changing everything to seq_cst and it didn't go away, so perhaps not ...
<jbjnr> hkaiser: ok
<jbjnr> other members cnnot post anything to IRC it seems
<jbjnr> what is the +v voice thing?
<K-ballo> members?
<hkaiser> heller: do the finding in the paper require us to change anything now?
<jbjnr> people like msimbers cannot post any moe
<jbjnr> more^
<hkaiser> jbjnr: let's invite him
<K-ballo> better yet, tell him to register
<hkaiser> or ask him to register with freenode
<K-ballo> so he doesn't need to be invited
<hkaiser> jbjnr: what would you suggest? I'd rather not have this spamm
<jbjnr> I cannot suggest anything since I know nothing abiut IRC, but jakub and Mikale asked me about +v voice and I have no idea what it is
<K-ballo> that's for users to speak in moderated channels, are we a moderated channel now?
<K-ballo> where's zao?
<jbjnr> hkaiser: "Our current definition of memory_order_seq_cst, especially for fences, is too weak. This was caused by historical assumptions that have since been disproved."
<hkaiser> K-ballo: is +m meaning it's moderated?
<K-ballo> no idea
<jbjnr> so basically we're screweed on power
<hkaiser> are we?
<jbjnr> think so
<K-ballo> yeap, we are.. that's not good
<hkaiser> well, then everybody else is screwed as well
<jbjnr> c++ is fundementally broken
<K-ballo> we should only be +r, not +m
<hkaiser> K-ballo: if I remove +m the spam starts again
<hkaiser> tried it yesterday
<hkaiser> well, let me try again
<K-ballo> so the spammers are still entering the channel? they just don't spam in silence
<hkaiser> I reset +m
<hkaiser> +r was already set, IIRC
<K-ballo> I don't know how to query existing modes
<K-ballo> figured it out, we are +crt
<hkaiser> yah, -m is now reset
<jbjnr> how do you set/query modes
<K-ballo> query with /mode #ste||ar, set with /mode #ste||ar <mode>
<jbjnr> thanks to both of you
<jbjnr> why not mode +n that seems to be applicable, stops people outside the channel from posting. Are they 'in' the channel
<K-ballo> they enter the channel
<K-ballo> they've been entering all morning today :/
<jbjnr> I see
<jbjnr> enter/spam/exit
<K-ballo> more like enter/spam/killed, but same thing
<heller> hkaiser: not sure what to do, just something that came to my mind
<jbjnr> oops
<jbjnr> sorry. was playing with commands and broken something
<K-ballo> /slap is not a supported command :/

<heller> ah, come on

<jbjnr> heller: want to see something awesome
<K-ballo> /msg chanserv info #ste||ar
<heller> jbjnr: always
<jgolinowski> hello
<jgolinowski> It works now :D I can type again
<K-ballo> jgolinowski: sorry about that
<K-ballo> unfortunately, so now can the spammers
<jgolinowski> K-ballo, but at least there is some level of protection: the +r flag
<K-ballo> I'm not sure it's working, we'll see
<jgolinowski> I was testing that when I am not "logged-in" or "registered with services" as the irc states that
<jbjnr> team gryffinfor wearing their silly hats. I hope this makes you jealous and gets you writing!
<K-ballo> we should probably still add +n, but I don't seem to be able to
<jgolinowski> so when I am not logged in then I cannot type on #ste||ar
<nikunj97> with current modes, I guess only registered users can type on #ste||ar
<jgolinowski> nikunj97, yep
<jgolinowski> but then again registration only requires setting up an email and then confirming registration with the code from the e-mail so there might be still registered spam accounts :(
<nikunj97> jgolinowski, from what I observed, most of the spammers used unregistered accounts (evident from whois)
<nikunj97> So I think we should get some sort of security with this
<jgolinowski> nice :D
<jbjnr> but once they are registered, they can be blocked
<jbjnr> (individually)
<jbjnr> so they would need to keep generating accounts
<heller> jbjnr: cool!
<heller> jbjnr: i am writing
<heller> Should be done soon (tm)
<jbjnr> write more - and faster!
<heller> Or less
<jbjnr> jut submit. they accept any crap
<heller> At least on IRC ;)
<heller> jbjnr: I trust you, you're a doctor!
<jbjnr> I'm looking forward to actually writing some code for the rest of the summer. Been away from the compiler too much lately.
<hkaiser> jbjnr: nice picture

<zao> jgolinowski: Success!
<jgolinowski> zao I see
<jgolinowski> so it means I am added as a member (can talk even though there is +n flag)?
<K-ballo> you are in the channel
<hkaiser> heller: yah, the speedup is significant if you have many small threads
<ms[m]1> hkaiser: that's a very cool speedup! jbjnr are you listening...?
<jbjnr> ms[m]1: listening
<jbjnr> stop chainging your name
<jbjnr> we should try it on the future overheads test
