up_the_ironsu did? hah, swear i didn't see anything
brycec didn't get a PS4
oh LOL, i see it now ;)
[11:21]
brycec:D good response time
I expect this to be resolved ASAP
[11:23]
up_the_ironstrouble is, i didn't get a PS4 either
so the problem is unsolvable
[11:23]
brycecheh [11:23]
up_the_ironsI waited in line at Fry's and Best Buy, not really seriously thinking I'd get one, but wth, just for fun. And indeed, they were both sold out before I got near the front of the line ;) [11:24]
brycecI miss Fry's...
I didn't really try either
[11:24]
pjsup_the_irons I think know the answer but I'll ask anyways. Do you offer any sort of LB services? ie, to 2 web server front ends? [11:25]
brycecMy lady wants one, but it's a chunk of change so we're going to hold off until prices drop, or she can't resist any longer (whichever comes first)
The last answer I saw to that question was "get n+1 VMs"
[11:25]
up_the_ironspjs: nope
pjs: u gotta build your own
yeah
[11:26]
brycecbrycec updates his "last answer" to be unchanged [11:26]
pjsup_the_irons figured.. just checking :) [11:27]
jpalmerbrycec: DNS RR, and haproxy, yo.
I *really* wish web browsers would start supporting SRV records. it'd make LB for web servers a much easier (and cheaper) option for the masses.
[11:32]
brycechm? it wasn't me looking to LB [11:33]
jpalmererr @pjs ^^ [11:33]
pjsjpalmer, yea I assumed that was for me :) [11:33]
jpalmer_http._tcp.domain.com IN SRV <-- should be a standard in zonefiles, and browsers should support it nativelike. [11:34]
brycecInteresting, I wasn't aware of SRV records for HTTP [11:35]
jpalmerno major browser supports them yet.
at least, not when I last looked ~1yr ago
[11:35]

Firefox ^
Wonder what the holdup is
[11:36]
***mike-burns has joined #arpnetworks
ChanServ sets mode: +o mike-burns
[11:38]
up_the_ironsyeah i was looking at that almost three years ago. SRV support would be awesome. Just like how all DNS resolver libraries support multiple resolvers, web browsers need to do the same. Only real way to do HA is when both server *and* client are HA aware. Anything less is just a hack. [11:38]
jpalmerhonestly, I think it's just that people don't really "get" SRV records, and as such.. are scared of them.
The first browser that supports SRV records though, will win my undying trust. I'll switch that same day.
[11:38]
toddfsometimes it isn't the browser but the underlying web framework, webkit having srv record support for example, would be a win for many reasons ;-) [11:40]
jpalmerI guess another part of it is.. people who don't understand SRV records will be insanely confused about how to serve a website on www.example.com and test.example.com (though, it's easy enough in reality to setup)
but man, how awesome would it be to have the ability to spin up a VM anywhere in the world.. and have it start taking part of your web traffic, with just a DNS change
[11:40]
pjsjpalmer yea, seriously [11:44]
brycecYou can still do that with just adding that VM's address to the LB :p
I think the bigger fear is that reliance on SRV (and in effect deprecation of A records) will break many dumb devices
So you'd have to keep A records and LB's around for old hardware that's not likely to see an upgrade
[11:46]
jpalmerA and SRV records can coexist.
and, adding the webservers to a roundrobin in DNS, provides no redundancy. if the server is down or overloaded, the request would fail, and continue to fail until the DNS TTL expired. not so, with SRV records.
[11:48]
brycecAnd why couldn't I just add more A records to my www record? Sure I don't get priorities and port numbers, but it still round-robins
SRV have no TTL?
[11:48]
jpalmerthe weights and priorities account for that. [11:49]
up_the_ironsif the A record to which your domain resolves is an IP that is down, your site is then down for that client [11:49]
jpalmerif the highest priority servers are down, it automatically moves to the next priority level. [11:49]
brycec(same as MX work) [11:49]
up_the_ironsyeah like MX [11:50]
jpalmerthey have a TTL, but the SRV rsource in and of itself, provides the rdundancy. whereas with an A record, (or CNAME) you'd have to wait for a TTL [11:50]
brycecup_the_irons: But with multiple A records returned, it's up to the client to choose which to use
Solution: 300s TTL :P
[11:50]
up_the_ironsweb servers do not re-try the "next" A record in RR DNS [11:50]
brycecservers? [11:50]
up_the_ironss/web servers/browsers/ [11:51]
BryceBot<up_the_irons> browsers do not re-try the "next" A record in RR DNS [11:51]
brycecWell shame on them. [11:51]
up_the_ironsif the client chooses an A record that is down, the request simply fails. at least that is my understanding
i'm not aware of a browser that retries all the A records until it finds one that is up. although, i haven't looked into it in a while, maybe i'm wrong...
[11:51]
toddfno, at least for webkit, it will try until it finds an address that works otherwise fail [11:52]
jpalmerif you request a DNS record, the DNS server will respond with them in an order. most resolver libraries will only try the first one returned. not "falling back" to others. it'd wait for the TTL to exire, then a new response from the DNS server would (hopefully!) respond with them in a different order. which may or may not happen. [11:52]
toddfbut the discussion should be expanded in scope
getaddrinfo returns a list of addresses (both A and AAAA)
[11:52]
jpalmerthe "A record fallback" thing isn't really a browser issue, it's a resolver library issue. [11:53]
up_the_ironsjpalmer: that is my understanding too; but toddf's comment about webkit retrying, that is news to me [11:53]
toddfit is the os lib preference as to how they are sorted (by default on some os'en it is AAAA first, by default on OpenBSD recently it is A first, though I override it by 'family inet6 inet4' in resolv.conf) [11:53]
up_the_irons(good news, that is :) [11:53]
toddfand then the list of addresses should be tried in sequence they came out of getaddrinfo() [11:53]
jpalmerwebkit likely recognizess the failure of the resolver, and takes measures to act on it's own. hell, they may even use their own resolver libs instead of depending on the OS libs. [11:54]
toddfit takes forever to timeout and retry on another address [11:54]
up_the_ironsi c [11:54]
toddfwhether google does this now or in the future or never, it would probably be smart for someone to write a web browser toolkit to connect to all addresses returned to by getaddrinfo() and whichever connect's fastest wins the wager of which server the browser will talk to for a given dns entry [11:55]
jpalmereither way.. no matter how you look at it, DNS RR using A or cname records is purely a hack that may or may not help in a given situation. SRV records, would always work appropriately assuming the resolvers aren't buggy. [11:55]
toddfat least in openbsd chrome will use libc resolvers, I had to comment my 'family inet6 inet4' trick when it was showing a given page badly on v6 but ok on v4 and of course it hit v6 by default [11:55]
............... (idle for 1h12mn)
mercutioi dno' tthink it'll make any difference myself
usualyl when you have multiple A records the browser will try them
if it gets connection refused
but most of the time when a site is down it doesn't give connection it just hangs
and in that situation i doubt browsers will change servers.
also the biggest complication with "load balancing" is the backedn server architecture needs to support being hosted at multiple locations
which is pretty simple for static files, but much more complicated for databases etc.
that said i don't think it'd hurt
and it would be nice if things like unable to reach host came back to operating systems in a timely fashion
rather than just hoping it'll work out sooner or later

my terminal turned it into a "?" when you sent it to the channel, haha
[15:24]

m0undsi'm learning about heroin from a computer based learning system at work
i have now learned that people inject heroin
[15:27]
phluxwat [15:28]
m0undsikr [15:28]
phluxyou must live under a rock brah [15:28]
mike-burnsDid the computer teach you the trick about injecting it between your toes? [15:28]
phlux^ [15:28]
m0undsi have now learned that prescription medications can be addictive [15:28]
phluxmike hides his track marks that way
he's also been known to inject it in the butt
but it doesn't get you as high
Its oldest sound value is probably /t͡sˤ/
wtf is that supposed to mean
how does one pronounce that
[15:28]
m0undsssssss [15:29]
phluxis it like the last line in "ba dum tss"
????
[15:29]
m0undsthat's what i'd guess, but without the t
ba dum t ssssss
[15:29]
phluxwhy without the t? [15:30]
m0undswell, i'd guess because i don't see a t in the pronunciation
that it probably doesn't have a hard consonant in front of it
but i'm no linguist
[15:30]
phluxa, a 't' is definitely there [15:31]
mike-burnsI think m0unds is missing some UTF-8 again. [15:31]
m0unds^^^^^^
that's the ticket
[15:31]
phluxo [15:31]
m0undsyeah [15:31]
phluxyeah he needs to fix that imo [15:32]
m0undsi figured it was there but it wasn't for me because no care ever
hahaha
nah
i'm a-ok without it
[15:32]
mike-burnsI had to figure out UTF-8 when I moved to Sweden. Now that it works, life is better.
It's ä-okej here.
[15:32]
m0undsdon't wait until departmental morale is affected to inform supervisors or managerial staff of drug addiction [15:32]
phluxm0unds: you should go try heroin i hear it's fun
but i've heard you need to take like twice as much as experienced users tell you to take. they only want you to take half of the real dose so they can get the rest for themselves
[15:34]
m0undsyeah, i've got a syringe ready to inject into my hog [15:34]
phluxare you gonna go butt, toes, eyes, or just plain ol' arm injection? [15:34]
m0undshog = euphemism for genitals [15:35]
phluxoh
going right for the dick of the first try? bold.
[15:36]
m0undsanything worth doing is worth doing right [15:36]
phluxi can't argue with you there [15:36]
mike-burnsLike UTF-8. [15:36]
phlux^ [15:36]
m0undsthing there is that i don't care [15:37]
phluxlol yes he does
don't listen to him
[15:37]
mike-burnsAnd SRV records. You should do that right, too. [15:37]
m0undsi care so little that i'm listening to a computer voice telling me about drug testing instead of enabling utf-8 [15:37]
phluxi just got this in pm: m0unds │ yo man how do i enable utf8 cause my irc is incomplete just dont tell anyone ok???
man
you need to move over to weechat too
[15:37]
m0undscan you guess why i won't? [15:39]
mike-burnsComplacency? [15:40]
phluxbecause you're too busy doing heroin? [15:40]
m0undsnah, don't give a damn, don't care [15:40]
phluxbecause, in your mind, it's still 1983?
i know it's one of the two i just don't know which atm
[15:40]
m0undsit sure is, the year before i was born
i do, however, care that the volume level for each slide in these cbl things is different
[15:40]
phluxwtf are you doing this training for?? [15:41]
m0undsbecause none of this computer-based stuff existed when i was hired, so they have no record of having done any of it 6 years ago
so now i have to do it before the end of the calendar year
[15:41]
phluxthat's better than my situation
we do it annually in the military
you should quit your job though for real
[15:42]
m0undsi just did, now what? [15:43]
mike-burnsNow enable UTF-8. [15:43]
phluxdo heroin, party like it's 1983, change your irc client, and fix utf-8
you have a busy night ahead of you
[15:43]
m0undsokay, so do heroin, do heroin, change my irc client and enable utf-8 [15:44]
phluxexactly [15:44]
mike-burnsI feel like '83 was more of a coke year than H. [15:44]
m0undsprobably
but that means i'd have to get cocaine and heroin
i figured i could just do it twice
[15:44]
mike-burnsIt can sometimes be easier to get both. [15:45]
phluxidk
i *did* advise that he take twice as much
[15:45]
m0undsyep [15:45]
phluxmy wife is watching some movie where tim allen is an amish dood
and it looks really lame
but if i tell her she might cry cause of the pregnancy hormones, so i'll just dwi
[15:45]
m0unds:q
haha, wrong term woo
[15:48]
phluxyou can set up vim-like keybindings in weechat if you want
then :q would work
[15:53]
m0undsi'd rather not because that means i'd be quitting regularly when i fail to grab the right terminal window
unless :q was bound to do something else
[15:54]
phluxgood point [15:54]
m0undsand now that i'm done with the training nonsense, i fixed utf-8
because it was enabled, just not set as this user's locale
[15:57]
phluxi thought you didn't care tho [15:57]
m0undsnot hwile i was trying to finish that nonsense
needed to finish it first
[15:57]
phluxyou should unset it so you can keep up the rebel persona [15:57]
