WhoWhatWhen
mercutioJC_Denton: You'll need to renew your certificate.
JC_Denton: If you send into support@ I can do it for you now. 		[00:14]
if you do: openssl x509 -in mycert-arpnetworks.crt -noout -text | grep -i "Not After"
you can see when your certificate expires.
that -i is redundant :) 		[00:20]
JC_Dentonyeah, i'm sure it was probably just a 365er
don't quite have time to do it, but i'll crank on it later 		[00:29]
mercutioall good [00:33]

plettmercutio, mnathani_: This is an E5-2683 which will be running Linux on bare tin like it was 2005 again, no virtualisation at all. And no, their dataset isn't huge. It's an ecommerce site with a few thousand SKUs [02:16]
mercutiowhy 96gb?
14 cores?! 		[02:17]
plettBecause hugely inefficient code [02:17]
mercutiois it dual cpu?
haha 		[02:17]
plettNope, single processor [02:18]
mercutiois 12x8gb?
is it even 		[02:19]
plettI think it is. I'm in the BIOS configuring raid at the moment, I'll see if it can tell me...
It won't tell me anything more than that it's 96G of ECC DDR4 		[02:22]
mercutioahh ok
yeah with ddr4 you can actually get 16gb chips affordably
and so i'd think that it'd make sense to go for 4x16gb or 8x16gb (quad channel on those cpu's) 		[02:23]
plettWhen I've got it running linux, dmidecode will tell me how many DIMMs there are [02:24]
mercutiobut you can always go to 192gb adding another cpu, and i don't think 16gb is actually cheaper than 8gb, just lower power use and affords more ability to upgrade.
yeah
i like dmidecode :) 		[02:24]
..... (idle for 23mn)
plettmercutio: dmidecode says 6x 16GB DIMMs [02:47]
mercutiooh interesting
i think that'll stop quad channel from working. but there's heaps of cache anyway
(and it may not mind) 		[02:47]
plettRAM speed isn't likely to be a concern [02:49]
mercutioyeah
not if lots of things fit into l2 cache
err l3? 		[02:49]
plettThis customer is on dedicated metal rather than a virtual machine on our vmware mainly because they value the performance of local SSDs over the HA of our normal offering [02:51]
mercutioahh
lower latency? 		[02:51]
plettThe latency of accessing SSDs in a SAN was upsetting their database performance [02:52]
mercutioheh
i wish there was better parallelisation
it's kind of weird when you check out what queries web applications do, and it's like they throw off lots of queries in series
so latency impacts performance and it doesn't parallelise
memcached is not the solution :) 		[02:52]
plettNo. In this scenario, Varnish is the answer
But that requires slightly more competent web devs than this customer is using - hence throwing 96G, 14 cores and local SSDs at the solution instead! 		[02:56]
mercutioheh :)
nvme?
i wonder what cpus ebay use, i find their site slow :)
actually i think that's partially because everything comes from east coast US 		[02:59]

brycecWow I totally didn't realize the ARP VPN certs expired after a year (not like it's hard to see either, I just wasn't paying attention). Glad I checked so I won't be surprised when it suddenly stops working in 2 weeks :p [09:49]

mnathani_Is Zayo one of the big players when it comes to IP Transit? [16:02]
mercutiomnathani_: you been watching outages@? :)
afaik they're cogent level quality
and i think they do a lot of cbd office buildings etc. 		[16:06]
mnathani_mercutio: you know it :-) [16:06]
mercutioso a lot of people will be single-homed on them.
yeah i kind of noticed but didn't think much of it. they got hit by the cables cuts in was it san jose recently
it was san jose or san francisco, i get confused between the two... although i think the cable cuts were reasonably wide 		[16:06]
mnathani_vandalism or accidental? [16:07]
mercutiovandalism
like over 10 in a year 		[16:07]
mnathani_not like those guys can connect and get free bandwidth or anything by cutting the cables [16:08]

mercutiolots were in fremont, which i know nothing of other than he.net has data centres there. [16:09]
***meingtsil is now known as meingtsla [16:09]
mercutiowow. i didn't hera about that, apparently sniper's bullets took out 17 transformers in 2013.
that just seems bizzare to me.
this only says 10 cable cuts, but i think there were some more after the article 		[16:10]
.... (idle for 18mn)
brycec(San Jose, Fremont, San Francisco are all in the same metro area, so no need to be confused between them, just lump them all together) [16:28]
mercutioahh ok
yeah i lump san jose and san francisco in my mind a bit so it's hard to remember which is which
i didn't realise fremont was so close
i know santa clara is close.
i should just say northern CA, right?
oh, wow, they're closer than i thought. less than an hour drive without traffic.
maybe without traffic is a hypothetical situation? :)
would san francisco bay area be a more precise way to group? 		[16:35]
..... (idle for 21mn)
brycecYeah probably
"Northern California" is a bit less precise :p
But considering those cities all basically border one another, it's best to lump them. 		[17:01]
mike-burnsAs an east coaster, I've definitely lumped them. "West", when around polite company. [17:02]
..... (idle for 24mn)
mercutiomy geography has definitely improved with internet use :)
although i'm still a bit patchy about lots of europe.. 		[17:26]
mike-burnsMoving to Sweden helped me learn European geography. [17:27]
RandalSchwartzhaving been in 55 countries taught me a lot [17:30]
mercutioRandalSchwartz: wow :) [17:32]
mike-burnsI find it helpful to take a train between countries, so that I can better understand the relational/spatial geography. [17:32]
mercutioi'd rather drive between cities
err countries
can't do that here though.
i suppose with long distance trains you could sleep on the train. 		[17:32]
mike-burnsI just did an overnight train to the middle of Sweden (and back, three days later). Would recommend. [17:34]
mercutiodid you sleep okay? [17:34]
mike-burnsQuite well. [17:34]
mercutiohangon, if you sleep on the train how does that help you understand the geography? :) [17:34]
BryceBotThat's what she said!! [17:34]
mercutiodo you have internet access on trains? [17:35]
mike-burnsTypically yes. Depends on all sorts of things, though. On this trip I had turned my phone off so I'm not entirely sure. [17:35]
mercutiosounds nice [17:36]
mike-burns(It was an outdoors trip, skiing the Jämtlandstriangeln.)
In this case I already know Swedish geography kinda well. 		[17:36]
mercutioit seems i don't have unicode support. [17:37]
mike-burnsOr I don't! [17:37]
mercutioyou get a ? too? [17:37]
mike-burnsI get the proper letter. [17:37]
brycecI saw the proper letter too :) [17:38]
mercutiodamn [17:38]
brycec"Jämtlandstriangeln." [17:38]
mike-burnsBut: I'm on local weechat connected to a weechat relay on a server. Locally I see the proper letter, but on the server weechat I see an underscore. [17:38]
mercutiois there something special you have to do with tmux/weechat for unicode support? [17:38]
brycecI'm on ssh+tmux+weechat [17:39]
mercutiohmm [17:39]
brycec(And frankly can't remember what, if any, I've done to make it work) [17:39]
mike-burnsAnyway, it's an 'a' with two dots over it. [17:39]
mercutiomy term type is screen rather than the 256 color one. [17:39]
brycecä I can even type it [17:40]
mike-burnsI have LANG=en_US.UTF-8 LC_CTYPE=en_US.UTF-8 in my env. [17:41]
mercutiooh i didn't think about LANG setting
weird, i don't have LANG 		[17:43]
brycecbrycec has LANG=en_US.UTF-8 [17:45]
mercutioi have LANG=en_NZ.UTF-8 on my desktop [17:45]
RandalSchwartzheh... you can create a git branch named Locohost.local:..r/Git/ziprecruiter % git branch -r | grep happy
origin/happy☺︎ 		[17:46]
mercutiohah [17:46]
RandalSchwartzheh you can create a branch named happy☺︎ in git, and push it to your server. [17:46]
