current #lca2010 keynote: http://www.lca2010.org.nz/programme/schedule/video/_mfc_128 #
really enjoying @BiellaColeman's keynote. great storytelling, inspiring. #lca2010 #
in the scaling the weta datacenter talk #sysadmin #lca2010 #
RT @newsycombinator: Java, Postgres developer job. Location? The South Pole http://bit.ly/6soLaV (cc: @gorthx, @dlangille) #
weta datacenters run at 25C (suggested was 20C) #lca2010 #sysadmin #
considering increasing temp to 28C (82F), using water cooling for storage, using DC power #lca2010 #
enjoying that i actually learned how to convert C -> F yesterday #arduinorules #
chris king looked at implementing a large-scale cooling system using water. nice to see data centers using it #lca2010 #
details: a luke-warm water stream would be created for all hvac systems to use & machines to reject heat into #
details: giant cooling tower located on top of the building for hot water to go into, and cooled water to flow out of (HVAC chiller-style) #
in data storage miniconf listening to talk on sheepdog, a distributed storage pool system from NTT #lca2010 #
now showing a video of the UI, node configuration, data distribution map. sheepdog is an adorable name for an EBS replacement. #lca2010 #
sheepdog is GPLv2, project page http://www.osrg.net/sheepdog/ #lca2010 #
watching @FallenPegasus present on memcached #lca2010 #
why not rely on mysql query cache? "it's a hack." heavy write load? "mysql query cache will fail." #memcached #lca2010 #
@jdub yeah, this in the context of "why not just use query cache and never memcached" in reply to jdub #
gonna hang out for @fuzzychef's relational vs non-relational talk (includes some categorization I'll talk about tomorrow) #lca2010 #
just heard a #redis shout-out from @FallenPegasus #lca2010 #nosql #
no new database design. but we have lots of new implementations, some of which are better! sez @fuzzychef #lca2010 #nosql #databases #
RT @stewartsmith: @selenamarie, @jdub: the mysql query cache is also single threaded. giant mutex. fail with > 1 core. #
re:mysql query cache @joshwaihi this seems like a balanced overview: http://www.mysqlperformanceblog.com/2006/07/27/mysql-query-cache/ in reply to joshwaihi #
just saw @br3nda walk in! #lca2010 #
"a lot of people don't want to use SQL." sez @fuzzychef. me: but you know what's worse? SPARQL: http://tr.im/KOZ7 #lca2010 #
@brainsilopdx might be talking with other hackerspace folks here at #lca2010 – anything in particular I should ask them? wellington has one! in reply to brainsilopdx #
@brainsilopdx ah great! Thanks. in reply to brainsilopdx #
Lovely lunch with @br3nda, @jarichaust, @emmajanedotnet, @pjf and james 🙂 #
Gorgeous day! #lca2010 http://twitgoo.com/bymm9 #
@pjf maybe more general so that we can include more services 🙂 some ideas: "boredom stream" (ppl yr bored with), "drama" (self explanitory) in reply to pjf #
@pjf AH. hmmm. then your first option is the best 🙂 in reply to pjf #
@obra @pjf then: WWW::Facebook::Friends::JSON will be sufficient. 🙂 in reply to obra #
RT @lhawthorn: case study from World Bank on use of #FOSS in Brazil. Slides & summary available from webinar. http://bit.ly/4ovigk #
headed to data storage for @devdas' talk on refactoring a large postgresql database #lca2010 #
PT @sigurdmagnusson: #lca2010 tip: nice evening to attend Wellington's free botanic gardens music. Bus/cable car/walk. http://is.gd/6yCy4 #
kicking it off with a warning about the foot-gun of rules, but they are also awesome. #postgres #lca2010 #
(also caught the tail end of Arjen Lentz's OQGRAPH talk: https://launchpad.net/oqgraph) #lca2010 #
@kartar awww. Are you at lca? in reply to kartar #
"anyone storing IP addresses in VARCHAR fields?" (no hands) Audience member: "liars!" #lca2010 #
@pjf I feel like we're some kind of hugs delta force. #
showing the use of rules to respond with an error to INSERTs to perform maintenance (and acquire locks) #lca2010 #postgres #
love expressed for transactional DDL inside of #postgres http://tr.im/KPKu #lca2010 #
RT @jonjensen0: Good notes on self-improvement, lack of self-confidence. Why I Feel Like a Fraud:
http://j.mp/7wniNe via @newsycombinator #
trying that again: @lhawthorn +1 how about we try the malaysian place then? http://www.kayumanis.co.nz/Kayu_Manis/Selamat_Datang.html #
here for cucumber-nagios "behavior driven infrastructure" #lca2010 #
talking about Mechanize and Webrat (ruby) in relation to http://cukes.info/ #lca2010 #
@kartar yes! maybe livecasts as well? http://www.lca2010.org.nz/programme/schedule/video/ video probably not up for a few weeks i hear. in reply to kartar #
showing email from martin england about using cucumber in relation to puppet. Puppet == build, cucumber == testing. #lca2010 #
(talk is by @auxesis btw #cucumber #nagios #lca2010) #
shout out for those still "hand rolling" (vs cfengine, chef, puppet) 🙂 it's ok. #lca2010 #
why do we need these complex tests? traditional monitors (ping/tcp) don't verify the right things. ASK THE RIGHT QUESTIONS! AMEN. #lca2010 #
@Ycros heh. context: you can still start using better tools to test your stuff 🙂 in reply to Ycros #
nice prequel of this talk from @kartar: http://bit.ly/5ODKf2 #lca2010 #cucumber-nagios #cucumber #ci #monitoring #
@Mettadore aww #blush in reply to Mettadore #
last link: behavior driven systems monitoring for telephony: http://tr.im/KPZ5 #lca2010 #cucumber-nagios #
cc: @e_monty RT @emmajanedotnet: Monty srsly looks like Steve Buscemi. I keep looking around wondering if I'm in a Tarantino movie. #lca2010 #
devdas bhagat talking about the theory of constraints (where's the bottleneck?) in relation to statistics #lca2010 #
@justindhunter the cucumber-nagios.org site actually has tons of good info. in reply to justindhunter #
getting ready to give a #bucardo replication lighting talk in the data storage track #lca2010 #
Make your own dropbox #lca2010 http://twitgoo.com/bzcck #

DRDB + mysql on the whiteboard! #lca2010 #
Drbd architecture in progress http://twitgoo.com/bzcxd #
Guess who thinks we should just have the conference ouside? 🙂 #lca2010 #
@gnat so, by exactly how many do sheep outnumber people in your fair county? Ps I have a question about a billboard. #
