ballen: written in java?
omfg

toddf

EPIFAIL
EPICFAIL

ballen

glad we're all on the same page then

toddf

lots of .c and .h in the (small) srcs to be java fully

[14:47]

ballen

yea its just the dog portion of the program

[14:48]

toddf

and I've yet to discover what that does

[14:48]

ballen

yea no idea

[14:48]

toddf

todd@liberty/p7 ~/sheepdog-2009102101/dog/src/net/osrg/sheepdog�1585$ pwd
/home/todd/sheepdog-2009102101/dog/src/net/osrg/sheepdog
todd@liberty/p7 ~/sheepdog-2009102101/dog/src/net/osrg/sheepdog�1586$ ls
ClusterInformation.java MasterGroup.java SheepdogException.java

ballen

I think its the agent on the storage nodes

toddf

Connection.java Node.java SuperObject.java
ConnectionCallback.java NodeList.java VdiOperator.java
DirEntry.java NodeLogOperator.java headers/
Inode.java ObjectOperator.java messages/
Log.java OpCode.java
Master.java Sheepdog.java
this does not look good

ballen

java's usually fast, just takes up a lot of memory
and is lame as hell to install

mike-burns

Yeah, my only issue with Java is the installation.

toddf

I have a friend who likes to use it because it is portable

ballen

yea

toddf

portable my ass, which version of java does what random java program want?

mike-burns

Is it?

ballen

thats the whole point of java

toddf

so you end up needing N jdk's for M programs

ballen

its portable

toddf

it is capable of being ported sure

mike-burns

ballen: Nah, the whole point of Java is C++ with GC.

ballen

mmk

mike-burns

The whole "write once, run everywhere" was slapped on by marketing after the fact.

ballen

so anyone have like a 80 node cluster laying around we could set this sucker up on
ah

toddf

my OpenBSD/macppc and OpenBSD/sparc and OpenBSD/zaurus and OpenBSD/sgi and OpenBSD/alpha and OpenBSD/hppa and OpenBSD/sparc64 and OpenBSD/mac68k systems have _no hope_ of running java

ballen

yea

vxp

nice zaurus

ballen

no java on OpenBSD

mike-burns

I had to join #freebsd to figure out how to install Java.

ballen

can run it on FreeBSD though

toddf

java works fine on i386 and amd64

ballen

heh

toddf

just that porting it to other archs is pain
and the one person who does a lot of OpenBSD work only has so much time...

up_the_irons

java is hardly portable; honestly, more code written in C runs on more platforms than any other language on the planet; this about that for a sec

toddf

that and to bootstrap w/out native bins from another arch one must have gcj and other things that are not fully working on random archs etc

up_the_irons

s/this/think/

mike-burns

Lots of high-level languages (with compilers/interpreters written in C) will run everywhere; Ruby, Scheme, Python, etc.

[14:53]

toddf

I agree. java is the least ported language. however, if you consider the %'age of users running systems capable of running java, things start to change, vs %'age of platforms and os's and such..

mike-burns

Yup, it's like Flash.

toddf

except flash works on my OpenBSD/macppc via gnash (well sortof but better than nothing)

ballen

wonder how much load Sheepdog would put on your network and relistically what you would need to run a cluster

toddf

one or two systems
I also note the lack of IPv6 support

[14:55]

up_the_irons

mike-burns: the thing with that is, if you can't run the interpreter, your code can't be ported to that platform (think embedded systems). so in a sense, C is more portal than Ruby, Python, etc... it has less dependencies

[14:55]

mike-burns

up_the_irons: Agreed.

[14:55]

up_the_irons

s/portal/portable/

mike-burns

(And s/less/fewer/)

toddf

the only case of AF_INET6 in their whole tree has to do with binding to a socket, and I daresay that's to support the abhorrent practice of v4 mapped v6 addressing in loonix

up_the_irons

ballen: bonding a couple GigE NICs, for just the I/O backend, for throughput of 2 Gbps full-duplex, would probably take care of any network issues

mike-burns

Pure historical coincidence that C is so portable; systems people just decided to port C instead of whatevre other langauges were lying around at the time (LISP, Smalltalk, FORTH, etc.). Good marketing helps.

up_the_irons

ballen: the disks would be slower

[14:57]

ballen

up_the_irons: problem being your writting out to X number of nodes for replication

[14:57]

up_the_irons

toddf: funny, Qsource (not present) who is a FreeBSD guy, always calls Linux "lunix" ;)
ballen: yeah, there's gonna be some slowness there; only question is "how much"
ballen: and can the replication happen asynchronously ?

[14:57]

ballen

yep exactly

[14:58]

toddf

the concept in general seems decent

up_the_irons

wth, my S.M.A.R.T. munin plugins don't work after a reboot on this new box.. but after a fiddle, they work again; not sure what i did

ballen

smart is dumb sometimes

toddf

if you have a large number of systems it could read from mem cache if it were actively reading/writing to/from blocks

up_the_irons

mike-burns: yeah

hi @ sshguard

obsidieth

its like 2 attempts per ip, ish.

yea sshguard is good
if you're running pf on FreeBSD or OpenBSD theres an easy way built in to it

so bored

[19:01]

visinin

write a blogging engine

[19:01]

ballen

done that: http://github.com/unilogic/scanty-redis
well thats a fork
but heavily modified

[19:01]

visinin

haha
touche
rewrite it in haskell

[19:02]

ballen

fuck that
not really a fan of anything thats not ruby

[19:02]

visinin

well that's just a shame

[19:03]

ballen

meh not really

[19:03]

visinin

you should try erlang!
it is delicious.

[19:03]

ballen

I'm sure it is
I really don't want to take the time to learn a new lang
nor do I want a language thats slower to program in

[19:04]

visinin

but you've never even used it :(
how can you make such an accusation?

[19:05]

ballen

what language is easier than Ruby?

[19:05]

visinin

honestly i can't stand ruby
so any of them
:)
python's its main competitor
i rock with python
i mean
i'll backpedal a bit
ruby is a pretty dope language
i just don't like it all that much

[19:06]

ballen

and thats how I feel about Python

visinin

fair :D
but there are other languages in the world

ballen

that there are

visinin

haskell and erlang are funky if you're not used to functional stuff
but then you've got, like, lua
or maybe io
why the lucky stiff likes io!

ballen

ballen checking out IO
so whats the point of IO

[19:08]

visinin

it's a language that does some cool things
just like all the other languages!

up_the_irons

lua is pretty damn fast
i found lua pretty damn easy to pick up just by looking

visinin

and by learning more languages you will be able to change your perspective on software development as a whole
that is pretty cool
yeah
lua's pretty straightforward

up_the_irons

i've only used lua to make imapfilter scripts, but it was a pleasant experience

ballen

visinin: yea to be honest I'm very unlikely to pick up a new language
not my forte

[19:12]

visinin

fair enough
what do you do mostly, then?

[19:12]

ballen

visinin

SA?

ballen

systems administration

visinin

ah, gotcha

ballen

and code on stuff for fun
for example http://unilogiclabs.com is a Sinatra app with Redis db backend
which is turns out is not as scalable as I thought it'd be, the redis db part

up_the_irons

http://www.arpnetworks.com is a Sinatra app :)

[19:14]

ballen

I'd use something like Cassandra, but I really would rather not have to install Java
could make Redis scalable, I have basic hash ring with replication setup

[19:15]

up_the_irons

ballen: Java is the evil about Cassandra, true, but we're using it at DigiSynd with great success; it is FREAKIN' FAST!!!!

[19:16]

ballen

but no managment of nodes coming and going
up_the_irons: yea I imagine it is

[19:16]

up_the_irons

ballen: the nice thing about cassandra is it is inherently redundant; master / slave replication is a major fail for HA

[19:16]

ballen

does Cassandra have more complex data structures, sets, list, etc

[19:17]

up_the_irons

TODAY IS INTERNATIONAL CAPS LOCK DAY

[19:17]

ballen

wtf a search for Cassandra on google turns up some interesting google image results
wtf=btw
wierd

[19:17]

up_the_irons

ballen: KEY / VALUE, AND THE VALUES CAN HAVE COLUMS
*COLUMNS

ballen

columns eh

visinin

chicago boss looks really cool

ballen

sooo explain columns

up_the_irons

why yes it does: http://www.wallpaperbase.com/wallpapers/celebs/cassandralynn/cassandra_lynn_1.jpg

[19:19]

ballen

thats the one

[19:19]

up_the_irons

ballen: like google BigTable

YOU GUYS APPARENTLY DON'T BELIEVE ME: http://capslockday.com/

[19:19]

ballen

nah just annoying

[19:20]

up_the_irons

LOL

[19:20]

ballen

it'd be an interesting study to search for girls first names
compare google image results
make conclusions based on name

[19:23]

yea it looks like Cassandra can emulate any data structure i'd need
btw Scribe is a pretty nifty centralized log service if you need such a thing

[19:33]

sroute

WHAT DAY IS CAPSLOCK DAY?

[19:38]

well NEVERMIND THEN

whats wrong? :O

[23:35]

up_the_irons

nothing :)
Some of my friends with bigger hosting companies all have Facebook pages for their co. One day, I will probably break down and have to do the same

[23:35]

ballen

what in the world would Arp Networks possibly gain from doing that
Facebook is a stupid platform
just everyone and the freaking brother happens to be on it

[23:37]

up_the_irons

who knows

[23:38]

ballen

I guess more SEO

[23:38]

up_the_irons

I'd gain FANS
;)

[23:39]

ballen

gawd

[23:39]

up_the_irons

yea i don't care

[23:39]

ballen

anyone know if its possible to jigger two 110 circuits to output 220v

[23:40]

up_the_irons

ballen: yes, it is, if they are of opposite phase

[23:41]

ballen

yea?

[23:41]

up_the_irons

ballen: that's actually how it is done, just at the breaker panel

[23:42]

ballen

ah yea that makes sense
since each leg of 220 is a 110 circuit

[23:42]

up_the_irons

up_the_irons hooked up a 50A 220V circuit in his garage
ballen: exactly

[23:43]

ballen

so thinking apartment wiring
figuring out if I could run a 220v espresso machine
figuring I couple of options
spliter on the oven

[23:43]

up_the_irons

i remember seeing a device that would take 2 110V inputs and give you a 220V, and it detected the phase and such

[23:44]

ballen

http://www.quick220.com

[23:44]

up_the_irons

yup, that's it
if your oven is 220v, I would just split that

[23:44]

ballen

curious why its so expensive
yea just have to check amperages on the machine and oven

[23:45]

up_the_irons

not sure

[23:45]

ballen

I'd hate to burn the apartment down

[23:45]

up_the_irons

the espresso machine wouldn't take more than the oven, i don't think...

ballen

by accidentally leaving the machine on and turning the oven on

hycer

9am here..italian coffee incoming

ballen

i suppose that'd just trip the breaker

up_the_irons

well, even if you did, if the wiring is correct, it should just trip the breaker

ballen

then the only problem would be if the oven is hard wired instead of a plug

[23:47]

up_the_irons

right

[23:47]

ballen

bah should just keep looking for a 110 machine

[23:47]

up_the_irons

yeah

ballen

be a different story if I had my own place

up_the_irons

i mean, you'd think they make those things with common voltage

ballen

yea

up_the_irons

220v sounds commercial grade

ballen

yea
it is
;-)

up_the_irons

hah

ballen

big league'in the espresso

up_the_irons

but if it is just for you, do you *really* need a commercial grade appliance?

ballen

no
theres a lot of used commercial machines on ebay, craigslist, etc for cheap
cheaper than a good prosumer one
thinking lots of cafes are going out of business around the country
or small restaurants offloading some higher cost equipment
