Love this idea. Would love to do the haml debate if it hasn't happened
by the time I get back from Europe. I could run for either side.
One interesting idea is to encourage people to play devils advocate
and not just fight for their legitimate opinions. We might learn
something.

This is a great idea, I think it'd probably result in much better
"introductions" to the debated technologies for those who dont know
much about them than the usual talk format.

If you can reach the reCAPTCHA site and the client can reach you, you

Visible as everything that's actually visible to end-users? (e.g.:
elements that are CSS set to display: none don't count)
If so, I seem Nokogiri is the way to go, as it also has a CSS parser
apart from HTML.

I've got no idea if this will work. I think the point here is to try and see

Yeah by all means, trying is the way to go, and props for the initiative.

Thanks Daniel, I like this idea and will give it a go!
It shouldn't be too hard to extrapolate into a generic web service swapping
plugin as well.

With great respect to your idea:

I can see the experience / ability / willingness to mentor others being
pretty attractive to employers (or even clients); with the framework for it
set up a certain way, I can see this (plus our native altruism of course)
helping to provide a good incentive.

Hi all,
Currently I am running Rails application online and it is running dog
slow. The current memory that I have on the VPS right now is 360MB,
which I thought was more than enough. How much would you recommend,
based on your experience, I should allocate for a Rails apps? Is there
anything els
That amount of RAM _can_ be enough, but it depends quite heavily on
your setup, and the particulars of the application design and how much
traffic it gets. A bit more information might help:
- what's the app?
- how much traffic do you get?
- what version of Rails are you using?
- does the app run
Hi Joshua
The best way when learning is to react to what's happening for your
app right now.
And the first question to ask is "is my slice swapping" -- that is,
has it run out of real memory and is resorting to disc based virtual
memory.
(assuming you're using linux of some kind) Use free -m to
To add onto that list, does your app have any memory intensive tasks
(such as importing and transforming data from an external source)?
For most apps, 360mb is more than adequate (and possibly overkill).

One simple thing to ensure if that you're not doing a
Class.find(:all)
If you've got an even semi large dataset, you'll hose your memory footprint by
loading up 1000's of ActiveRecord objects. I know, it's a mistake I've made
once. User.find(:all) in a Facebook app, was a stupid thing for me to
More importantly, it depends how many instances of the Rails app you are
running. If Passenger is spooling up 2+ then you might want to look into
restricting it to 2 max

Hey Cam,
About a year ago, ActiveRecord::Batches was introduced to avoid that
exact problem. You can use either find_each() or find_in_batches() to
iterate over large collections without loading the entire collection
of records into memory. Those methods default to 1000 record batch
sizes
That's exactly right, I use find_in_batches regularly these days. Each of those
methods limits the amount of AR objects instantiated and put into memory at any
given point in time(which as I found out the hard way is really important).
find(:all) will just write a select with no limit on it, and
Hi Nathan and Cameron,
Thanks for the pointers. I think I use alot of find(:all) in the code.
I am going to revise the code again. =)

Hi Simon and Lachie,
These are the setup that I use :
- Rails 3 with Passenger and nginx
- Database: MariaDB in the same box with the app
- Traffic, not so much as nobody know about it yet

Hey Joshua
It seems really fast to me, just clicking around a little.
Could it be the passenger spin up you're noticing? Where passenger
kills idle apps after 5mins of idle, and on first use they need to be
spun back up.
(You can turn this behaviour off with passenger_pool_idle_time: 0; in nginx

find(:all) / all() is ok on models that will only ever have a few
records (CustomerType, ProductFormat, etc). You just need to be careful
when using it on models

Hi Joshua,
The app is _using_ 2 gigs on your demo box? Or you have 2 gigs of RAM?
Seems like there shouldn't be any reason for it to be slow (sorry,
it's still down, so I can't see if it's slow for me); I'd definitely
have a look at your DB schema; see if the queries you're running are
using an
Hi Simon,
The demo is running again now. The 2Gigs of RAM is my development
computer, the demo box runs on a VPS with 360MB RAM.
If you want to see the DB schema, I have dumped it here:

Thanks heaps mate.

Is there any indexes on those tables?

I was wondering the same thing, there don't seem to be many. It is
exceptionally slow to display the first page after the login.
But that should only be a problem if there's a whole heap of data in
there; what's the largest table? Also, my question about the RAM was
actually how much is being us
looks perfect - thanks!
