WhoWhatWhen
up_the_ironsi saw a patchset a while back that made it possible to run VMs within VMs ;)
imagine you being able to run your own VMs within your primary VM
you could buy a big VM and make a few littler ones
[00:00]
ballenI'm afraid it will cause BSD to fall much to the wayside in the future as virt becomes ubiquitous
yea you can run ESX instead of a VM running in ESX or Workstation
inside*
using for testing
[00:01]
up_the_ironshehe
or virt support will get better in the BSDs
[00:02]
ballenyea and for god knows what reason NetBSD is leading the way with Xen support [00:03]
up_the_ironsyeah, it's funny that I got NetBSD working on Xen years ago [00:04]
ballenshould run a few Windows 7 vms
round out the offering
[00:05]
up_the_ironsme? [00:06]
ballenya [00:06]
up_the_ironsno way
;)
[00:06]
ballenwhy not [00:06]
up_the_ironsagainst my religion [00:06]
ballenoh come on Windows isn't that bad [00:06]
up_the_ironsalthough I do have 10 WinXP VMs running at DigiSynd
/kick ballen^H^H^H^H^H^H^H^H^H^H^H^H
;)
I got asked for Windows VMs once
[00:06]
ballenlmao, just messin I haven't used a windows box in many years [00:07]
up_the_ironslicensing issues are kinda a pain [00:07]
ballenyes [00:07]
up_the_ironsIf I take on other OS's, the next would probably be OpenSolaris (after NetBSD) [00:08]
ballenbe fun to play with OS X Server though
OpenSolaris is a mess
all Solarises are
[00:08]
up_the_ironsI manage a couple XServe's [00:08]
ballenimho [00:08]
up_the_ironsOS X Server is nice in a way, not nice in others [00:08]
ballenyea [00:08]
up_the_ironsif you have a problem, it is hard to google the solution [00:08]
ballentypically do it apple's way [00:09]
up_the_ironsi had to call apple support one day
it was pretty good
[00:09]
ballencool
never had to deal with their server support
also getting laptop parts replaces
always*
replaced*
bleh, typing bad need to sleep
[00:09]
up_the_ironshehe [00:10]
ballenalright I'm off for the night, good luck with migrations [00:10]
up_the_ironsi want to be able to script a FreeBSD fs resize (my experiment for tonight)
ballen: tnx, g'night!
[00:10]
ballenif you figure out the resize, let me know
I'd be interested
anywho, night

up_the_irons... [03:48]
oh man
OH MAN
my life is forever changed...
I just live migrated a VM!
122 packets transmitted, 122 received, 0% packet loss, time 121059ms
Not even a lost packet!
ballen|away: so good news / bad news -- turns out live migration works with my current kvm / qemu version, so it is not totally borked. Bad news is the VM i migrated was a Linux VM. So there must be something about the FreeBSD guest that is freaking it out. Nevertheless, something i'm sure an upgrade would fix
this is some f'in incredible shit i just witnessed...

jeevyet-another-lobbyist writes to mention that Facebook addiction has finally caused real world consequences, at least for one would-be burglar. It seems that 19-year-old Jonathan Parker couldn't stay away from the popular social networking site, even long enough to rob a house. Parker not only stopped mid-robbery to check his Facebook status on the victim's computer, but left it logged in to his account when he left. [12:48]

ballenmakes my brain capable of writting more on this horrid paper [18:04]
up_the_ironsballen: your thesis? [18:07]
ballenindeed [18:07]
up_the_ironshow long is it so far? [18:07]
ballen60 some odd pages [18:07]
up_the_ironswow
what are you aiming for?
[18:07]
ballenshrug, not page limit [18:07]
up_the_ironsgotcha [18:07]
ballenjust till I have the content [18:07]
up_the_ironsyeah [18:08]
ballenI'd say it'll be another 30 pages +
if I'm lucky and concise
with all the screen caps I need to add it'll add another 10 pages on top of that
oh btw no need for the FreeBSD 8 Beta VM anymore ended up just setting it up at work
however when you're getting read to test 8 let me know
ready*
I must say though Latex is the best thing ever to write big papers in
[18:08]
up_the_ironsroger on FreeBSD 8
heck yeah, LaTeX is da bomb
i did all my papers in school with it
[18:13]
ballenyea same [18:14]
up_the_ironsesp. physics and math papers [18:14]
mike-burnsThe best part of LaTeX is the editor. [18:15]
ballenI just use TextMate [18:15]
mike-burnsOh you're missing out. [18:15]
ballensomehow I doubt this [18:16]
mike-burns... you're missing out on vim! [18:16]
ballenmeh [18:16]
mike-burnsBut that was kinda my point: writing papers with LaTeX is better than with e.g. AbiWord because you get to use any editor you want. [18:17]
ballenaaah
thought there was some bundled LaTex Editor
[18:17]
up_the_ironsup_the_irons scratches head
yeah
i was like..
[18:18]
mike-burnsThere's LyX, but I don't see the point. [18:18]
up_the_irons"what LaTeX editor?"
LyX is actually quite good
I used it heavily
[18:18]
ballenlove using the word Hereunder [18:18]
mike-burnsNext time I have to write a paper I'll probably try LyX. [18:18]
up_the_ironsi had hot keys for writing complex math formulas DOWN
so I could bust out really nice formulas fast.. i would look at the generated LaTeX, and it was way complicated to do that by hand ;)
[18:18]
ballenyea
its wicked nice
[18:20]
up_the_ironsI had a professor at UCLA.. went to his office, he had a HUGE office.. took "Computer Systems Modeling" with him. Noticed him writing a paper in vim, on his Sun workstation, writing LaTeX markup
i thought that was pretty hard core
[18:22]
ballenheh [18:23]
jeevthat's disgusting [18:23]
mhoranNah man, that's how it's done. [18:24]
mike-burnsvim has a sweet LaTeX package. Billions of aliases and whatnot. [18:25]
up_the_ironsmike-burns: o'rly? nice
jeev: yeah man, *that's* *how* *it's* *done" ;)
[18:25]
mhoranSpeaking of vim awesomeness, I gave my boss enough of a hard time that he's using macvim or whatever the native app is. [18:26]
up_the_ironsnice [18:26]
mhoranNow to get the Emacs users switched over ... [18:26]
mike-burnsHa, good luck switching them! [18:26]
mhoranI was asked to install Emacs on aa production server today, and had to comply. :(
I don't want X on my production box!
[18:26]
mike-burnsI really want to try emacs, but I really don't want to install it. [18:26]
up_the_ironsmhoran: there was no emacs-nox11 package? [18:26]
mhoranThey wanted the X package.
So they can click around.
Ugh.
[18:27]
ballenemacs is lame [18:27]
up_the_ironsmhoran: and if it's a FreeBSD box, I think it let's you pick the non X11 version if you install from ports
mhoran: oh oh
they *WANTED* it that way
[18:27]
mhoranNo FreeBSD. :( [18:27]
up_the_ironsfuck them [18:27]
mhoranYup. [18:27]
up_the_ironsso many vim users here, this is awesome [18:27]
ballenballen hates that one of his developers insists on using it [18:28]
***heavysixer has quit IRC () [18:28]
mike-burnsWe have one emacs guy at my job, but at least it's a programmable editor. It's not TextMate or RedMine or whatever. [18:28]
mhoranThe thing that made my boss want to use TextMate was Cyberduck integration -- but I guess this Cocoa port of vim has Cyberduck support as well. [18:28]
ballensomeone needs to write a grammar checker that has more knowledge of the english language then a human [18:29]
mhoranThe Emacs X-forward thing is awful, though. [18:29]
ballenI'll give you a little cyberduck integration [18:29]
mhoranballen: How do you get a human with more knowledge of the English language than a human to write a grammar checker with more knowledge of the English language than a human?
I think it'd be easier to solve the halting problem.
[18:30]
ballenhave two humans do it [18:30]
mike-burnsBam.
Also, I approve of any sentence about grammar that uses poor grammar.
[18:30]
mhoranHuh. That was easy. [18:30]
ballenhah
seems like someone should start a startup that tackles the grammar check problem
and truely solve it
or at least improve it
we need to source some english profs
[18:31]
mike-burnsKnowing grammar isn't the problem; parsing natural languages is. [18:33]
ballenindeed [18:33]
mike-burnsEnglish profs are pretty mediocre at programming. [18:33]
ballenindeed
however they are good at english
think of the profits to be had
if there was a program that could perfectly correct a paper
[18:33]
mike-burnsAh that's too subjective. [18:34]
ballenthe school children would rejoice
english grammar lessons would become outdated overnight
[18:34]
mike-burnsPlease no. [18:34]
ballenhah
see thats step one
step two after everyone can't talk
is to be able to parse voice
and playback the correct sentance
its gold I tell you
[18:35]
mike-burnsIn the future all conversation will sound like Jerkcity. [18:36]
mhoranHUGLAGHALGHALGHAL [18:36]
mike-burnsThe future is here. [18:36]
ballenit may be the downfall of society as we know but when has that stopped someone from making money [18:36]
up_the_ironsLOL [18:37]
ballenmaybe we should just go with the mechnical turk approach, hire a shit load of minimum wage people to correct papers
actually
a combination
do that for a year or so
gather data
go from there
[18:44]
up_the_ironsLOL [18:46]
ballenwonder if could source K-12 schools
copies of papers before and after corrections
it would seem after some point you'd have enough data
to catalog every single error and correction
possible in the lang
[18:47]
quick, someone recommend a techno artist
anyone, anyone?
rap?
any music what so ever
[18:55]
ThorgrimrDidn't realize you were looking for music selections based on the requests :) [19:04]
ballenya
just need something new, getting bored of my library
[19:04]
mike-burnsThe problem isn't knowing grammar, just to state the obvious. [19:07]
ballenof course
its knowing how people fuck up grammar
[19:07]
mike-burnsYeah, in a sense. It's parsing non-grammatical sentences. [19:08]
ballenyep [19:09]
mike-burnsThere are ambiguities in grammatical sentences; parsing non-grammatical ones is basically impossible. [19:09]
ballenwonder if anyone has looked at the fesability of playing a shuffle game with the words in a sentence. Looks for sentances that match known grammar rules.
the brute force method
[19:10]
***bobbyw has joined #arpnetworks [19:10]
mike-burnsHuh, that's a fun idea. [19:11]
ballenthen go go worth and start substituting similar words
wow
retarded sentance
then go further and...
[19:11]
mike-burnsDoesn't scan. [19:12]
ballenwith more and more comuting power at the desktop
computing*
[19:12]
mike-burnsSure, all we need are a bunch of FreeBSD VPSes.
Oh i have to go to a bar now.

up_the_irons: questions on live migrations, can you live migrate to a VM that has more RAM or larger HD?
cause that'd be the hotness
somehow I doubt the live RAM part is possible
[20:55]
.............................. (idle for 2h28mn)
jeevi just spent 14 hours trying to get simcopter working
and it finally is but crashes often
[23:23]
mhoranballen: Memory "ballooning" is a feature of Xen. I'm not sure if the same exists in Xen.
The HD upgrade is certainly possible, however I think there would have to be some downtime due to the fact that the FS has to be modified.
However that process is quite simple.
[23:27]
ballenyea maybe hotplug an additional drive [23:28]
mhoranThe memory balloning requires some client support, however.
Yeah. You couldn't resize an existing drive, but you could certainly hotplug.
Same with CPUs.
[23:28]
ballenany idea if KVM supports it [23:28]
mhoranMemory is more complicated, hence why the Xen implementation is complicated.
Not sure.
up_the_irons had to restart my VM to add an extra disk.
So I'm guessing, not at this point.
[23:28]
ballenI know ESX has all that fun stuff
with a wicked expensive license add-on
[23:29]
mhoranYeah. Their licensing is ridiculous. [23:29]
ballenschema for key/value db's is a pain
just thought it'd be cool to be able to scale a VM vertically on the fly
[23:31]
mhoranYeah.
For sure.
We're getting there!
KVM has certainly come a long way.
[23:32]
ballenthat it has, I'm really quite impressed with it [23:32]
mhoranI can't wait to dump Xen at work. But by the time I finally get the chance to do that, maybe Xen will become stable again. :/
I'd love live migrations, though.
But, not working.
Bunch of hacks.
[23:33]
ballenyea, live migrations is so freakin cool
that feature alone makes virtulization so much better than bare metal installs
[23:33]
mhoranYeah. [23:34]
ballenif you had it hooked up to BGP you could move a VM into another datacenter, across the world, etc [23:35]
mhoranThat's actually something I'm working on. [23:35]
ballennice [23:35]
mhoranBut since live migrations don't work, :(
But hopefully BGP.
Our DR setup right now is pretty sweet, though.
[23:35]
ballencool [23:36]
mhoranComing from a company where we ran on bare minimum of everything, this is a big change for me, heh.
We actually have backups! Haha.
[23:36]
ballenthats always a nice change
lmao backups are good
[23:37]
mhoranHowever, they don't test their software. >:o [23:37]
ballenhah [23:37]
mhoranWhich means, it breaks in the middle of the night and I get the call. [23:37]
ballenneither do I [23:37]
mhorantsk, tsk [23:37]
ballenI'm a sysadm not a dev [23:37]
mhoranIt's easy!
Write the tests and the code writes itself.
[23:37]
ballenyaaaa [23:38]
