Speaking of, is anyone using weechat autojoin with keyed channels? I can't get it to work. It joins the keyed channel and nothing else.
[13:48]
staticsafedescription: comma separated list of channels to join when connected to server (example: "#chan1,#chan2,#chan3 key1,key2") (note: content is evaluated, see /help eval)
note where the spaces are, those matter

mercutiook, so i just found out that zsh supports shared history between shells but isn't enabled by default
that's like been one of the things that have bugged me for ages
[14:06]
mhoranstaticsafe: Ah. all keys go at the end? That explains it.
mercutio: Awesome! I need to enable that.
[14:06]
I want shared search history but not up arrow. [14:14]
mercutioheh
setopt inc_append_history
setopt share_history
in .zshrc
i dunno why you wouldn't want up arrow
it also enables timestamping
[14:22]
.... (idle for 16mn)
m0undszsh is awesome
it's the shell for wizards
[14:38]
BryceBotYER A WIZARD m0unds [14:38]
m0undsthanks, BryceBot [14:39]
.... (idle for 15mn)
mercutioi been using zsh for ages
but i always knew there were advanced things i wasnt' doing/making use of
but even without those it worked better than ksh etc
[14:54]
mike-burnsA prior student of mine introduced me to it, around 13 years ago. I thought he was just some clueless hipster.
Turns out it's a great shell! And he's not clueless!
[14:55]
mercutiomike: did you try it? [14:56]
mike-burnsI eventually did. Took two years. [14:56]
mercutioi mean straight away
ahh ok ;)
it gets like that
it's like how some people are still using screen
lots of things i've been using for ages now
[14:56]
mike-burnshttp://bit.ly/1chYnUF - the guy who fixed this bug (Taylor) is the student who introduced me to zsh. [14:57]
BryceBothttp://bit.ly/1chYnUF -> http://www.daemonology.net/blog/2011-01-18-tarsnap-critical-security-bug.html [14:57]
mercutiomutt, vim, zsh,
mike, cool :)
[14:57]
mike-burnstmux is still hipster nonsense. [14:57]
mercutiowell it's useful if you think your net might drop
or you want to reboot where you're connecting from or such
[14:58]
mike-burnsI mean tmux instead of screen. [14:58]
mercutiohave you seen screen's source code? [14:58]
mike-burnsHah. [14:58]
mercutioactually on that note have you ever looked at gnu source code? [14:58]
mike-burnsHave you seen echo's source code?
mercutio: I run this: http://bit.ly/1bdX1FS
[14:58]
mercutioonly the gnu one [14:59]
BryceBothttp://bit.ly/1bdX1FS -> http://www.meetup.com/The-Classical-Code-Reading-Group-of-Stockholm/ [14:59]
mercutioheh cool [14:59]
mike-burnsWe just did a group reading of pwd.c, and before that true.c . We also had a pilot (not listed) where we read echo.c . [14:59]
mercutioi've been writing my own implementation of curl [14:59]
mike-burnsAwesome. [15:00]
mercutiobeen pretty slack about it
but try ldd `which curl`
[15:00]
mike-burnsHeh.
zsh: ldd =curl
[15:00]
mercutio% ldd `which curl` | wc -l
38
[15:00]
mike-burnsOn FreeBSD: 8. [15:01]
mercutioreally [15:01]
brycec28 on Debian7 [15:01]
mike-burns27 on my Debian. [15:01]
mercutiohmm i get 6 on freebsd
wow
and the binary size is smaller than ubuntu too
[15:01]
brycecI got 15 on my FreeBSD [15:02]
mercutioweird
this is freebsd 9.2
[15:02]
mike-burnsI wrote my own 'ls' two years back. Fun exercise. I did it in Haskell, though. [15:02]
brycecSame. Built from ports though. [15:02]
mercutiohmm
i did a terminal emulator OS
it booted from grub though
but all you could do is use a terminal in it heh
[15:02]
mike-burnsWith our powers combined we can re-write BSD! [15:03]
mercutiolike serial terminal [15:03]
mike-burnsHah. [15:03]
mercutiothe network stuff was being annoying
it seems much simpler before you start working on it
i had what i thought was an ideal environment too :/
grub would network boot it
and had a separate 386 to boot
which booted pretty fast
so could just make on the dev computer
[15:03]
mike-burnsI have long given up the idea that any programming problem is simple. Being a project manager will do that, though. [15:04]
mercutiobut writing tcp/ip stack and network driver is kind of more complicated than i thought it would be
this was years back though
maybe i should try again :/
[15:05]
mike-burnsIt's only more complex now. [15:05]
mercutiobut this time as a xen virtual machine
nah it's simpler if you just rely on virtio :/
[15:05]
mike-burnsOK let me know how it goes. [15:06]
mercutioi was reading about people doing micro OS stuff with xen
where you compiile a program to run as a virtual mcahine
which includes everything it needs
and everything runs as ring 0 or such
(is it still ring 0 if it's a virtual machine?)
anyway kernel and user space is one
[15:06]
mike-burnsThis gets you lower memory usage? [15:07]
mercutioand less context switches
and more separation
[15:07]
mike-burnsSmart. [15:07]
mercutioi thought it was a nifty idea
they were using some werid programming language though
really it's file system stuff that is probably the most complex
i can't find it now
ahh it was erlang they were using
[15:08]
mike-burnsThat's not a weird language. [15:11]
mercutiohttp://erlangonxen.org/ [15:11]
mike-burnsThough, I'm biased: it's one of the most popular languages in my city. [15:11]
mercutiocurious
are you in a hipster town
i actually know very little about erlang
[15:11]
mike-burnsI'm in the town that invented it, so ... I guess that's cheating. [15:12]
mercutiopcase_word =
fun(X) ->
lists:map(Upcase, X)
end.
err U on the front
ahh
well i dunon that looks weird to me=
[15:13]
mike-burnsLooks like Erlang to me. [15:13]
mercutioyes looking for code examples
but i keep finding short blurbs
[15:13]
mike-burnshttp://bit.ly/1chZOCH - here's an actual thing. [15:14]
BryceBothttp://bit.ly/1chZOCH -> https://github.com/klarna/jesse [15:14]
mike-burnshttp://bit.ly/1be080P - this one's complex, too. [15:14]
BryceBothttp://bit.ly/1be080P -> https://github.com/klarna/meshup [15:14]
mercutioactually it doesn't look too bad [15:14]
mike-burnsIf you want it to look prettier, I recommend Elixir. [15:15]
mercutiois that a drug?
http://erlangonxen.org/
[15:15]
mike-burnsYes, but it's also a programming language. [15:15]
mercutiogo there
and press escape
[15:15]
mike-burnsHah.
Yup, definitely Erl nerds.
[15:15]
mercutioheh
well i reckon the idea is noverl
novel
[15:16]
jpalmermost of the software we write at work, is erlang [15:16]
mercutioand me just wanting to play with C minimal OS on Xen is not really novel
but hey :)
i'm boring.
[15:17]
mike-burnsjpalmer: What do you work on? [15:18]
jpalmermike-burns: we have a communications platform for use in hospitals. [15:18]
mike-burnsSeems like a good use case for erl. [15:18]
jpalmerwe're rewriting it from the ground up for the next version (still in erlang) the CTO for grandcentral/google voice joined us and is leading the rewrite. [15:20]
mike-burnsEvery time I hear about a big erl project, I also hear about a rewrite. [15:20]
jpalmerwell, this rewrite isn't due to erl. it's due to.. growing pains. As we were developing it, our developers wanted to do stuff the right way. our executive team wanted them to meet unrealistic deadlines the sales team had made for customers. so features were rushed, and shortsighted, etc
that whole saga
[15:21]
mike-burnsYup, I hear ya. [15:22]
mercutioi think things should always be rewritten
but then i hate maintaining legacy code
but the philosophy of a rough draft, then a rewrite sits well with me
mike-burns: have you considered rewriting classic utilities in your group?
i seem to find i understand things better when i reimplement
than when i read
[15:25]
............. (idle for 1h3mn)
brycecI love rewriting code! I hate rewriting and/or rediscovering bugs. [16:33]
................... (idle for 1h33mn)
mnathaniIs there a way to determine at which hop a file transfer slows down, ie whats the bottleneck. Say the transfer is going from Amsterdam, Europe to Los Angeles, CA. I can perform tests on both ends [18:06]
....... (idle for 30mn)
mercutionot really
not unless you can try from the individual hosts in the path
[18:36]
mnathaniDon't really have access to the hosts in the path [18:36]
mercutioyou can figure out if it's sending or receiving of traffic being problematic
yeah
most people don't
you can "guess"
but yeah you can't really tell
[18:36]
mnathaniInternet routing is best effort once it leaves my network.. [18:37]
mercutioi love the term best effort
what's your route like?
[18:38]
mnathanintt / Level3 [18:39]
mercutiowell i have a ntt each way test
and it's fine
so i'm tempted to blame level3 :/
well 20megabit}
+
which is fine to me
[18:39]
mnathaniI am presently getting 6 megabits on an scp transfer [18:42]
mercutioin which direction? [18:42]
mnathaniits actually from chicage to ARP/ lAx [18:42]
mercutioyou're not using dropbear are you?
oh
i got 100 megabit from chicago before
[18:42]
mnathanichicago provider is liquidweb [18:43]
mercutiothis was from steadfast
my other chicago host is congent
cogent
ick
but seems to dl fast
abbout 4 megabytes/sec
are they using openvz?
with chicago it shouldn't be window size issues
even with 64k window size it should be faster than that
[18:43]

***r0ni has joined #arpnetworks [19:16]
m0undscogent is really inconsistent [19:20]
mnathanimercutio: Its a dedicated server in either Chicago, or somewhere in Illinois [19:23]
m0undsi thought liquidweb was in detroit?
or near
[19:27]
mnathaniMy mistake, its in Lansing, MI
halfway between chicago and detroit pretty much
[19:36]
m0undsthey're a good provider [19:37]
mnathaniYup
Who is a really great hosted email provider? (please don't say office 365 or google apps)
[19:38]
m0undshaha
office365 is
intermedia is another
despite you asking not to say office365, it's a good service :)
[19:40]
mnathaniDoesnt have to be hosted exchange [19:41]
m0undsi've used it since launch for my stuff. i resold intermedia for a number of years, their platform is really reliable and good
well, hosted exchange is all i work with for hte most part
i've heard fastmail is ok
luxsci is good
but expensive
[19:41]
mnathanik [19:45]
staticsafeFastmail++ [19:48]
mjpany reason to pay for hosted webmail/pop/imap these days? (I can understand exchange) [19:54]
staticsafemjp: as opposed to? [19:56]
mjpfree stuff [19:57]
staticsafemjp: a certain saying comes to mind [19:57]
mjpstrength in numbers? :) [19:58]
m0undshaha
i stopped managing my own MTAs and stuff because tuning SA and stuff was such a chore
[19:59]
staticsafemjp: I'm currently using Fastmail and much prefer if over Gmail/Google Apps [19:59]
mnathanidoes fastmail support a catchall mailbox [20:02]
staticsafei do not know actually [20:02]
mnathaniGoogle Apps does, but Office365 does not [20:02]
m0undssuch a spam hole [20:02]
staticsafei don't like catchalls
spammers love them though
[20:03]
m0undsyeah, it's not a great practice because it just sort of guarantees higher spam delivery rates
staticsafe: do you use fastmail's web interface or a client?
[20:03]
staticsafem0unds: web interface
which btw is very much superior to Google's offering
[20:03]
mnathanihow about alias, so you dont waste mailboxes for sales@, info@, contactus@ etc [20:04]
staticsafemnathani: ofc
i use a separate alias for most stuff
like arpnetworks@example.com
[20:04]
m0undsyeah, same
either alias or mailnull
username.alias@mailnull.com >> your address
mostly use that for forum signups and public stuff
[20:04]
mnathaniwhat about filters or rules for categorizing mail [20:06]
staticsafei recently found out the specific alias I use paypal has been sold out
got spam on it
mnathani: their backend uses Sieve
you can write your own rules by hand
or edit the webui thingy
Sieve is so much <3
also the people behind IMAP know their shit when it comes to e-mail hosting
s/IMAP/Fastmail
[20:06]
BryceBot<staticsafe> also the people behind Fastmail know their shit when it comes to e-mail hosting [20:10]
m0undshahaha [20:10]
staticsafei suppose the people behind IMAP too :P [20:10]
mnathaniIs there calendar support [20:10]
staticsafemnathani: nope [20:10]
m0undsoh, boo.
oh boy, sharknado is on amazon vod
[20:11]
mjpfair enough then :) [20:15]
mnathaniIs fastmail by opera? [20:29]
staticsafenot anymore
its a company on its own now
[20:30]
mnathaniWhat can you use the SMS included on a Premier account for? [20:32]
staticsafeno idea, I have the "Enhanced" level [20:33]
..... (idle for 21mn)
mnathanistaticsafe: would you like to pm me your username to put in for referrer at fastmail [20:54]
staticsafesent. [20:55]
mnathanithanks [20:59]
................... (idle for 1h34mn)
mike-burnsAnother vote for Fastmail here. [22:33]
