Possible to make custom priorities in Resque? (As 3 (low, normal, high) isn't enough)

I believe it isn't... depending on the usecase you could use different queues with separate workers (and more workers for the high priority ones) for example
varun_ has joined #ruby-lang
yfeldblum has joined #ruby-lang
varun_ is now known as Guest36120
tectonic has quit []
<maloik_>
another option is one worker across different queues, I believe... `rake resque:work QUEUE=high,lesshigh,medium,lower,lowest`
<maloik_>
if that makes sense kimegede
<maloik_>
it'll take jobs from the queues in that order
<maloik_>
downside there could be that if high has a ton of jobs and lesshigh does too, it'll most likely do all of the high queue's jobs first

Hi i would like to develop a library in ruby and extend the data structure library done in the gsoc project https://github.com/kanwei/algorithms

by implementing B trees binary search trees,interval trees and all

But does lesshigh even exists?
kiddorails has joined #ruby-lang
<Guest36120>
So is there anyone who could guide me, when i have doubts.
<maloik_>
that's just the name of the queues
<maloik_>
you could call them anything you want
<maloik_>
they're not the same priorities you mentioned
rahul_j has joined #ruby-lang
<kimegede>
Ohh... that's naming :)
<maloik_>
(I wasn't aware of those 3 levels you mentioned)
<maloik_>
ohh there you go, that looks like the exact thing I mentioned
<maloik_>
you could add in more right there
<maloik_>
but as I said, if there's jobs in the high queue 100% of the time it'll never get to the medium or low queues
<Guest36120>
Are you referring to me.
<kimegede>
But that is only the naming again right?
<maloik_>
correct
<kimegede>
Okay thanks

no clue there, I don't know the first thing about algorithms
<Guest36120>
Ok so do you know anyone who does so i could email him about my ideas.

No idea where you'd have to go for that... you could try the issues in the project you mentioned, perhaps /r/ruby or the ruby-talk mailing list

Starting to feel a little sorry for that guy. I'm not confident I know enough about Ruby to really answer his question but based on what knowledge I do have (and the fact this project even was started) I get the sense that the answer to his question is that Ruby isn't used as a high-performance language where such structures would be necessary. I think it would be cool for them to exist but it's not something that is a major focus for most of the users

I want to 'subtract' the values of one hash from another, something like this: https://gist.github.com/ecnalyr/b714e14eb8751676d476 -- Rails had a method called diff that looked like it would help out, but it's been deprecated. Does anyone know of an elegant solution to this problem?

One place where I love procs is for recursive methods that need a setup. Instead of having the method call itself and re-pass a bunch of extra params after initialization, and instead of a second method, create a method with recursive lambda inside it.
dorei has joined #ruby-lang
<Phrogz>
The lambda has access to all the params from the method, so if they don't need to change on the call stack you can just access them (or mutate them, if you're into that sort of thing).
