2012.11.15 Weekly Check in

• 13:31 <grant_h> Hey guys, Frank and Mele are on vacation the next couple of weeks so they won't be joining today
• 13:32 <demory> grant_h, yep, they mentioned that last week. David T is still out too
• 13:33 <demory> so its probably just us and abyrd + kpw today
• 13:33 <demory> anyway we can still do a quick check in
• 13:33 <abyrd> hi everyone
• 13:34 <demory> i'm mainly working on the calltaker interface. hope to have something to show before the break next week
• 13:35 <abyrd> I had a call with grant_h and Mele about OSM review processes and they passed on a bunch of experience and documentation
• 13:36 <abyrd> we're going to present this to people here in Paris and try to get a community effort going to systematically verify data quality and compare with jurisdictional data
• 13:37 <abyrd> I've also been working on the analyst batch processor with some feedback from Jordan
• 13:37 <abyrd> and doing some profiler runs on various AWS instances
• 13:38 <abyrd> conclusion #1: despite recent improvements in memory consumption, running a NYC graph on an m1.medium is asking for problems
• 13:38 <abyrd> (though it almost works, even the graph build!)
• 13:38 <abyrd> the rest of the observations are here: https://github.com/openplans/OpenTripPlanner/wiki/PerformanceNYC
• 13:39 <abyrd> Also prepping for a potential big project in the Netherlands
• 13:40 <demory> abyrd, wow, those performance visuals are great. are those automatically generated by the profiler?
• 13:41 <abyrd> I did these by hand looking for good angles
• 13:41 <abyrd> I think the automated results should include response time vs. trip length (since it's obviously correlated) and the log-log plots are informative
• 13:42 <abyrd> the data is pulled from a profiler DB but the plotting still needs to be scripted
• 13:45 <grant_h> I created GTFS for a couple ferry shuttles on the Willamette and got those up and running
• 13:45 <grant_h> http://maps5.trimet.org/totp.html?purl=/osm?submit&fromPlace=45.098873,-123.069200&toPlace=45.093784,-123.011779&mode=TRANSIT,BICYCLE&min=TRIANGLE&triangleTimeFactor=0&triangleSlopeFactor=0&triangleSafetyFactor=1&maxWalkDistance=4828&time=10:35%20am&date=11/15/2012#/
• 13:45 <grant_h> (you have click "Plan your trip")
• 13:47 <demory> grant_h, looks good
• 13:48 <demory> actually, grant_h, i had a question about the calltaker interface
• 13:49 <grant_h> ok, sure
• 13:49 <demory> so, right now i'm working on the search history -- currently, there's a concept of a user (a calltaker) and searches are linked to a user in a database
• 13:50 <demory> so when a calltaker logs on w/ their username, they see a window w/ the last 10 or so searches they did
• 13:50 <grant_h> ok
• 13:50 <demory> of course, each time any option is changes, a new search is generated, and these can add up quickly
• 13:51 <demory> i'm wondering if we should introduce the concept of a 'call', with searches grouped by call
• 13:51 <demory> since a single call may include a dozen or so searches
• 13:52 <demory> that could make it easier if they're trying to pull up a search from hours earlier -- they would see a list of calls with times, rather than potentially hundreds of searches
• 13:52 <demory> and when they opened the history for that call, they would see the individual searches
• 13:53 <grant_h> sounds like a great idea to me, when the call takers are looking through the history its usually when a caller has phoned back in
• 13:53 <grant_h> this seems like it would make it much easier for them to retrieve the set of trips they're looking for
• 13:54 <demory> yeah, i think so. although, this means there would need to be some way in the webapp for calltakers to indicate a call is starting/ending
• 13:54 <demory> maybe just a 'call' widget with a start/end button?
• 13:55 <grant_h> Sounds good to me
• 13:55 <demory> ok, cool
• 13:56 <demory> this could also give you data on average call length, searches per call, etc. -- not sure if the call system already captures that or not
• 13:56 <demory> but all this will be stored in a db that can be used to generate reports, etc
• 13:57 <grant_h> not sure it the current system catches all of this, but it would definitely be a positive
• 13:58 <grant_h> I think the history capabilities will be a big improvement over what they're working with now if this works out
• 14:00 <demory> grant_h, great. also, one semi-related question -- when a calltaker "logs in" on the webapp, do you know if that needs to be authenticated with some external user database?
• 14:01 <demory> (for now, a user just specifies a username, no pw, that is used to tag their searches in the db. but i figured that might need to be made more secure/advanced)
• 14:02 <grant_h> not sure about that, I'll send out an email and get back to you
• 14:02 <demory> sure, no rush
• 14:02 <demory> ok, i think that's it for now, thanks
• 14:03 <grant_h> no problem!
• 14:03 <demory> anything else for the checkin? abyrd?
• 14:03 <abyrd> I think that's all for now.
• 14:04 <grant_h> oh, do either of you know where the ferry icons are called on with the OTP
• 14:04 <grant_h> within
• 14:04 <abyrd> oh, one other thing demory, do you handle the otp.org dns?
• 14:05 <grant_h> like the ones used here: http://sfbay.deployer.opentripplanner.org/#/submit&fromPlace=37.777736,-122.425096&toPlace=38.102650,-122.241075&mode=TRANSIT,WALK&min=QUICK&maxWalkDistance=840&time=11:29%20am&date=9/13/2012&arr=Depart&itinID=1&wheelchair=false
• 14:05 <demory> abyrd, no, not sure how that's set up. maybe check w/ anthony?
• 14:06 <grant_h> sorry meant, to say *within OTP's code
• 14:06 <abyrd> I was thinking it would be useful to have some symbolic names for the instances running profiler components to avoid using random ec2 names.
• 14:10 <demory> grant_h, not sure about the ferry icons. i can see them in the images folder, but don't see exactly where they are used
• 14:10 -!- inkybutton [[email protected]] has joined #opentripplanner
• 14:10 -!- inkybutton [[email protected]] has quit [Changing host]
• 14:10 -!- inkybutton [~inkybutto@unaffiliated/inkybutton] has joined #opentripplanner
• 14:11 <grant_h> ok, no prob
• 14:12 <demory> some of the other mode icons are used in https://github.com/openplans/OpenTripPlanner/blob/master/opentripplanner-webapp/src/main/webapp/planner.css, starting around line 670
• 14:16 <grant_h> great, thanks
• 14:16 -!- inkybutton [~inkybutto@unaffiliated/inkybutton] has quit [Ping timeout: 252 seconds]
• 14:19 <demory> ok, if there's nothing else, we'll have our next chat in two weeks (next Thurs being a holiday for most of us)
