maybe to gather all data rom these websites and put them on my server for caching

but those search bars use javascript. not sure how you'll run that, but there are javascript interpreters for ruby

I'm trying to scrape this webpage http://d.pr/i/pDPu ( Source: http://pastie.org/6326746 ) every day to get any updates to my schedule. The thing is, the schedule is updated every thursday and a second row is added for my next weeks' schedule, until sunday comes when the first week ends and is gone, and the second row moves to the first row. Then a second row is added next thursday and so on.

Hey all. I have a decorator function that formats datetimes for UI output. I need to check that the input time is not nil, otherwise the strftime fails. I have the code working fine, just wondering if this is the "idiomatic" way to do it? def format_time(time) ; time.blank? ? nil : time.strftime("%e %b %Y %H:%M:%S") ; end
<ryanf>
TomJ: you can just use "time ?" instead of "time.blank? ?"
<ryanf>
the only reason to use blank? is if you think it might be an empty string or something
<ryanf>
so then it'd be "time ? time.strftime" etc
<ryanf>
or you could do "time && time.strftime"
<ryanf>
or you could do time.try(:strftime, "%e %b %Y etc")
<ryanf>
or time.strftime(...) if time
<jblack>
Paradox: that looks pretty useful for anything restful
<TomJ>
oh nice, thanks ryan. silly, of course I could just do 'time'. but I didnt even think of time && - I think I like that best actually, no reason to explicitly return 'nil' in a ternary

2.0 has a few nice things. Doesn't feel all that 'big' to me though. They're releasing it to coincide with the 20th anniversary of ruby's release - hence 2.0 - so I guess they had an artificial deadline and couldn't make it as big an upgrade as it might otherwise have been. Biggest disappointment for me is that I see nothing at all relating to performance improvements. correct me if I'm wrong, but I think 1.8 -> 1.9 was a bigger upgrade than 1.9 -> 2.0
<Hanmac>
but ... chars does not return an array directly

Hi guys
<halfdan->
How to you generate a random time that is normally distributed across a 24h period?
<jblack>
oh, that's easy.
<Hanmac>
the intigration is not 100% perfect. .. i mean you could install the lib and the other so files into different dirs and install them simultany ... but you could still only install one "ruby" bin .. (and gem still list only 2 archs, not more)
<dmonjo>
lambda vs proc?
<jblack>
generate a random number between 0 and 86400. then add that to whatever time you want to start from.
mneorr has quit [Ping timeout: 252 seconds]
<halfdan->
jblack: damn, that's really easy
<TomJ>
Most of my Ruby experience (until this month anyway) was in sysadminning it - rails apps. I found the best way was to set a GEM_HOME for every app. e.g. Capistrano deploy app1 to /opt/mycompany/apps/app1/, with GEM_HOME set to /opt/mycompany/gems/app1 . You use more disk space installing gems multiple times, but it's much cleaner - no interference, I can clear out all gems and start again with one rm , etc. bundler does a good job on its own but I like to
<TomJ>
them separate as well. With that setup, I've never really had any gem problems at all. And it's easy to package, too - just package apps/app1 && gems/app1 (usually in separate packages)
<halfdan->
thanks!

I've got a library method that expects a block that is to be run in a callback. I've got an implementation of the callback as a method.
<rekado>
I want to feed the method into the library method without wrapping it in a block.
<rekado>
Can this be done without the ugly plumbing?
<rekado>
this works, but is ugly:
<burgestrand>
rekado: method(methodname) will give you a method instance, that responds to to_proc
<burgestrand>
rekado: so, for example, some_method(&object.method(:methodname))
<burgestrand>
rekado: object is the object that has the method you want to pass as a proc, some_method is the one accepting the callback, and :methodname is the name of your method on object that you want to pass as a proc
<rekado>
burgestrand: hmm, I've tried that but failed.
<rekado>
burgestrand: I'm going to check again.
<burgestrand>
rekado: :)

Actually I was working for a startup that wants to make something like this. But I was unsure whether developers want a service like livedocx with a visual designer probably, where you could design a PDF in browser and then call an API to generate the PDF with some data.
<Xeago>
kushkella: make the designer aspect optional imo
<kushkella>
xeago: What do you think of this?
<Xeago>
the services I currently know of, have crappy api's
<Xeago>
bad security practices
<Xeago>
and don't export as a trillion of formats
<Xeago>
do pdf right
<kushkella>
So what other options do you think are good to design the template?

Got it.

seperating the document template creation and the api, is actually a good thing tbh

as long as you keep stuff nicely versioned, and don't throw errors when a field gets removed by some weird c-level dude

i.e. generate server key and cert, generate client key and CSR, sign client CSR with server cert. server verifies clients with its own certificate. client includes its own cert and key when making a request to server

i think i'm confused as to why the client needs to send a key along with its cert when the server cert did the signing

nope, banished - lets them ditch legacy code and no point since 1.8 is already patch-dead and end-of-life in June. If a Rails shop wants to Run 1.8 with no security patch support, heaven help them (and they have to do it on Rails 3-or-lower).

you can use the redirection inside ``

$stdout.reopen perhaps?
