jlgaddisprobably gonna write an article over the weekend about my stats yesterday (72,567 total page views, normal average is ~2,000) and how well my vps/nginx held up. =)
so if nothing else maybe you'll get a new customer or two out of it. seems like you usually do whenever i write something about arp.
really fucking impressed w/ nginx. several months ago, i decided to try it out when apache shit itself at waaaaaay lower levels.

pjsjlgaddis is it static html or serving something behind nginx? [11:51]
......... (idle for 42mn)
jlgaddisit's wordpress, so php
i use a caching plugin though
the first time $page is requested, it generates .html and .html.gz versions of the page. on subsequent requests for $page, it'll serve those up instead, as long as the cached version hasn't expired
also, all the static stuff (images, .css, .js, etc) is served up by amazon cloudfront

up_the_ironsdon't ask for an android charger at LA RubyConf
i got weird looks
then i asked for USB Type B cable (the regular standard charging cable)
weird looks again
up_the_irons is bored
[13:35]
jdoeI really, really need to find a new job. There are currently 5 people in a remote office working on the problem of "Is a machine powered on" for me :/ [13:39]
up_the_ironsLOL
jdoe: what do u do?
[13:39]
mike-burnsmike-burns looks at up_the_irons weirdly. [13:40]
toothjdoe, hilarious.
cue "how many admins does it take to find a power switch" joke
[13:41]
jdoeup_the_irons: I'm a sysadmin. [13:43]
jlgaddisup_the_irons: they're ruby devs, what do you expect besides blank stares? :P [13:44]
jdoeup_the_irons: the remote office is in buttfuck nowhere, has no useful technical staff, and has poor infrastructure (flaky power/internet) -- so naturally I've been tasked with replacing their POTS system with voip.
kill me now.
[13:44]
toothjdoe, I am sending you a package which you should open right away. do not pay any attention to the ticking. [13:45]
jdoeproblem solved.
root cause: several of my coworkers can't distinguish betwen a 1U that's on and a 1U that's off.
taking the rest of the day off with a bottle of JD.
[13:54]
up_the_ironsjlgaddis: LOL
jdoe: hah
do i need to bring out my x serve pic again?
[14:01]
jdoesure. What is it? [14:01]
up_the_ironslooking.. my netbook is slow... [14:04]
jdoemy only (recent) server room wtf is http://falseprophet.ca/~jdoe/fusing.jpg ... not pictured: the door that opens (literally into) that rickety table, that it was just sitting there for a long time, etc. etc.
can't find the "THESE WALLS ARE ASBESTOS, LEAVE THEM ALONE signs, next to giant holes knocked in the walls" picture :/

omg
jdoe: what the F is that thing??
[14:06]
jdoedunno what the proper name for it is, I've always heard them called fusing cabinets.
I believe in that case it's linking local stuff to CA*net (internet2 if you prefer)
[14:08]
up_the_ironsjdoe: crazy
I just opened up 3 slots for 4GB beefy VPS', thinking of running a special at $89, or even $79 each; only three left, first to get 'em gets 'em!
i wonder how much 8GB sticks of FB-DIMMs are...
up_the_irons googles
[14:13]
jdoenot THAT bad. [14:19]
up_the_ironsif anyone cares, I have almost 900GB of FB-DIMMs in my whole cluster, all Corsair. Only 1 stick has failed. So, go Corsair! [14:19]
jdoehaha.
jdoe stabs the fuck out of whatever silicon mechanics ships
[14:20]
up_the_ironsLOL [14:20]
jdoewe've had a *lot* of that go bad. [14:20]
up_the_ironsjdoe: o'rly? [14:20]
jdoeyeah. I think I've replaced at least one stick from every machine.
though it's not quite as bad as whatever's in the HP blade server.
[14:20]
up_the_ironsoh wait, excuse me, not Corsair. Crucial!
i always get that mixed up
[14:20]
jdoeI do like crucial. [14:20]
up_the_ironsbeen quite reliable [14:22]
jdoeI dunno, I've never had problems with desktop ram the way I do with whatever's in these boxes. [14:29]
up_the_ironshaha [14:41]

jpalmerin my entire life, I've ordered a shitton of ram for myself and customers. I've found "crucial" to be good RAM. and in that time, only 1 stick needed to be returned. and even better, their RMA process was painless. they overnighted the cross-shipment. [15:35]
up_the_ironswow nice [15:45]

ninoryea good point
quality ram matters
i wonder what arpnetworks buys
[16:24]

jpalmerninor: up_the_irons just said they buy crucial
up_the_irons == garry == owner
[16:29]
ninoroh
i used to use corsair
was really nice. but that was years ago
silicon mechanics? i used to use their servers too
they're only a few miles from where my datacenter was
er sorry, they're up here in Seattle
[16:42]
........ (idle for 36mn)
mhoranYeah I've had good luck with Crucial too.
Had Corsair as well. No issues.
I really haven't had any RAM issues. So I'm a bad sample.
[17:19]
jpalmerjpalmer just re-enabled IPv6 on his VPS. didn't configure it when I installed CentOS6. [17:25]
jdoecentos :|
ninor: I have nothing against SM. I suspect our woes are environmental and/or bad luck.
[17:39]
ninorjdoe, oh i didn't even read anything. did you have a bad experience with some gear from there?
mhoran, would we even KNOW if we got bad ram?
i mean i wonder, how fragile is our data? speaking generally
there's bit rot on disk/disc, and in ram if shit goes sideways, how does that manifest?
[17:44]
jpalmerdepends on the level of "bad" but you'd see data corruption, odd behaviors, lockups, and possibly even "random" reboots. [17:45]
jdoeyou very probably wouldn't see any of that since it's all ECC ram... [17:46]
ninori wonder if there's any way to put safety checks in operational data in the way zfs does for persisted data
yea but i mean, if you were to put checking for 'this' into software, what would that look like?
[17:46]
jdoeunless a stick dies, the only person who's likely to know is up_the_irons, and only because he's going to get log spam. [17:47]
jpalmerjdoe: *if* it's ECC ram, correct. but not all ram is ECC ram :P [17:47]
jdoeno, but basically everything in a server you spent more than $20 on is. [17:47]
ninorim not even talking about arp
i'm speaking generally, in computing
[17:47]
jpalmeroh oh, in the context of ARP, and our vps's? No.. we'd never probably know. [17:47]
ninork i must be doing something wrong here. [17:48]
jdoeright. [17:48]
jpalmerninor: *generally* if it's non-ECC, you'd likely see what I mentioned above. [17:48]
ninork well sorry [17:48]
jdoeYOU SHOULD BE >:|
haha.
[17:48]
ninork and what would a software layer do to manage that
and overlay it to build in resilience
[17:48]
jdoenothing.
because you can't trust the software layer.
[17:48]
ninor*sigh* [17:48]
jdoesince it's running out of ram :P [17:48]
***ninor has left [17:48]
jpalmersoftware would have a hard time dealing with faulty RAM in any sane way. [17:49]
jdoelol
wasn't expecting that.
[17:49]
jpalmerjpalmer gets the impression that ninor was a little uptight.. [17:49]
jdoeseems so. [17:50]
jpalmerahh well. /me goes back to editing the maps at waze.com [17:50]
