WhoWhatWhen
brycecmnathani: xmonad is a tiling wm, which means (broadly speaking) windows equally share screen space maximally. ex: if you have 4 windows open, they all take up 1/4 of the screen. And some people prefer that (like me, at least on *nix systems. I just don't like it on Winders and OSX) [02:25]

m0undsdouble xp weekend for members in planetside = lots of new targets to kill
i was annoying high BR VS and TR players w/my reset NC character, capndelicious 		[07:19]
staticsafeyeah [07:20]
m0undskilled a couple BR100 MLG idiot pilots with a stock reaver w/airhammer (reaver shotgun) and got rage tells from them :) [07:20]
staticsafei was wondering why i seemed to have suddenly gotten better, turns out a lot of lower BRs [07:21]
m0undsmuahaha [07:21]
staticsafebut yeah i should try piloting again
repairing maxes all day gets old 		[07:21]
m0undsyeah
i get really tired of support stuff after a while. i gave up on squad/platoon stuff for a long time because it turns into REPAIR/HEAL ME NAOOOO 		[07:22]
staticsafei need a gun with a lower recoil than the one I have currently [07:23]
m0undsi wish the corvus was available for VS engineers
that thing has absurdly manageable recoil and is pinpoint accurate 		[07:24]

brycecmercutio: There's a certain amount of functional overlap in all tiling wm's... I wouldn't say one is better than the other though, it all depends on your usage. Give 'em all a try and see what fits you best. [09:55]
The big ones I know of are awesomewm (my current preference), xmonad (my previous preference, but I didn't like Haskell and awesome was being talked up quite a bit), i3 (pretty cool, but its global tagging didn't work well for me with multiple monitors)
There are plenty of others too, but I can't think of their names
(I want to say spectrwm and stumpwm too, but can't recall of those are real and tiling) 		[10:00]
plettI use i3wm (another tiling wm) now, after phlux in here mentioned it. [10:12]

mercutiobrycec: i've only tried ion and awesome
but been using ion since 2001...
i kind of want to try subtle when i tried googling 		[16:44]
m0undsgah, weechat keeps wigging out and drawing weird
it's like split at the 2/3 mark, and the whole right side of my terminal is filled with |............ 		[16:47]
RandalSchwartztmux does that sometimes [16:49]
m0undsoh, ok, so it's tmux? [16:50]
RandalSchwartzare you using tmux? [16:50]
m0undsyep [16:50]
mercutiotry resizing it slightly? [16:50]
RandalSchwartzyeah, if there are two windows to the same session, it can only paint the smallest window
so maybe you have it open twice? 		[16:50]
m0undsthat's gotta be it
yeah 		[16:50]
mercutiooh what randal said makes more sense [16:51]
m0undsi do, on my workstation
yup
now i know - small window open on my windows box upstairs
haha 		[16:51]
RandalSchwartzheh [16:51]
mercutioi've had some kind of screen corruption with weechat too [16:51]
m0undsterminal on my mac is screen width and drops down like the console in quake
yeah, i had corruption w/weechat and i resolved it with /window refresh 		[16:51]
RandalSchwartzyeah, I'm really liking tmux
never go back to scren
screen too 		[16:51]
m0undswas just gonna try the steam streaming thing on my mac (from my pc)
just to check it out 		[16:52]
RandalSchwartzfinally got all my ports rebuilt in poudriere [16:52]
m0undsnice - resolved the python thing? [16:52]
RandalSchwartzyeah,
now I just have to find a time to uninstall all the existing packages, and reinstall the new ones 		[16:52]

jpalmerRandalSchwartz: mosh + tmux + weechat = pure joy. [17:21]
RandalSchwartzmost + tmux + emacs :)
mosh 		[17:22]
jpalmerthere is just something amazing about being able to establish an ssh session, travelling between various networks with different IP's, different latencies, etc.. and never haing to re-establish the SSH session. just open up my laptop, and I'm instantly back in my session. [17:23]
RandalSchwartzyeah… mosh is cool [17:26]
jpalmerI have clients in alaska, with 1700ms round trip times, and 70% packet loss. mosh isn't cool.. its a necessity ;)
especially with --predict=experimental lol 		[17:27]
RandalSchwartzsounds like when I'm on a cruise ship
800 ms ping 		[17:27]
jpalmerit took me a bit of time to get used to the vi/vim visual artifact oddities with teh experimental prediction, but now it's second nature. [17:28]

novaeSo it's just like what, buffered screen over ssh? [19:59]
brycecNo
though I'm having trouble explaining what it *is*
but "screen" isn't part of it
It's just a more reliable transport for high-latency/loss links
It uses SSH to connect and authenticate with the remote host, then uses its mosh protocol (UDP) to transfer encrypted data
In addition to a more resilient protocol, it features "prediction" for the client
eg. rather than waiting for the 'g' you just typed to be drawn by the far-side, it draws the 'g' itself and it will update it once the far-end does. 		[20:10]

CaZeWhy would you want that? [23:51]
mnathaniRecursively copy files from one disk to another [23:52]
up_the_ironsyeah, what is up with the multi thread req? [23:52]
mnathaniMy use case is a windows box that needs to be backed up before it can be re-formatted
normally I boot into a live linux disk and simply scp or tar the files to another location
but this time I came across a machine with around 350 GB of files small and large and cp took almost 4 hours to complete to another local disk 		[23:52]
CaZeThreading would make it slower, if anything. [23:54]
brycec^^
Easy to test - run several cp's concurrently, each handling a different subdirectory
(or rsync, or tar|tar...) 		[23:54]
mnathaniwould multiple instances of an ftp client work, each set to skip if the file exists?
all the ftp clients set to upload the same directory to the same server 		[23:56]
brycecThey'd probably run all over one another [23:57]
CaZemnathani: What is the bottleneck in your use case? [23:58]
brycec(eg: they'd all say "XYZ doesn't exist" at the same) [23:58]
mnathanithe single thread or process working on an individual file, one by one [23:58]
CaZeIt's not i/o? [23:58]
mnathaniCaZe: not i/o
if I was doing like one large file, more likely to hit i/o limit
but 100,000 small files like few kb not so much 		[23:59]
