Comment on Setting up Postgres + Postgis on OSX by nahum

Alternatively you could use http://phppgadmin.sourceforge.net/ which I’ve not yet installed - but it’s actually what the main guy at my next gig uses. It’s like phpmyadmin but for postgres.

I really hate pgAdmin, this program just doesn’t feel like OS X and it is buggy, I really want something like cocoamysql for postgreSQL in OS X.

Comment on Starting simple with Rails caching by Michal

Michal — Fri, 19 Dec 2008 14:51:28 +0000

Nice writeup.
I agree that the very very important thing is to keep the whole caching system maintainable and simple. And this approach of caching smaller fragments seems to help with that.
Hope to read more from you on the topic soon.

Comment on Be careful how you count in Rails by Jens

Jens — Thu, 18 Dec 2008 12:28:05 +0000

Thanks for the nice article. I ran into a problem with count and named_scopes I couldn’t solve. I would say it is a rails bug (still there in 2.2.2), but obviously not an urgent one. Maybe you have an idea to workaround that. (see http://rails.lighthouseapp.com/projects/8994/tickets/1349-named-scope-with-group-by-bug)

Thanks in advance

Comment on Nginx upload awesomeness by nahum

nahum — Tue, 18 Nov 2008 21:24:41 +0000

I presume you mean the ‘upload module’ rather than ‘upload progress module’? I’ve not used the latter.

Ngnix doesn’t lock the mongrel instance. I’ve tested this by having a single mongrel running, uploading a 200mb file and still been able to surf around the site no problems. This is exactly why I implemented this for a client.

If the upload module isn’t used nginx will still buffer the file to a temp location on disk. Only once it has received the whole file it will send the request through to mongrel with the file in the request itself.

So large files being sent in requests can cause blocking problems while the request is sent and then your app deals with it - compared to just being told by Nginx where it is on disk which is much quicker.

Cheers,
Nahum.

Hi Nahum,
Does nginx upload progress module still lock the mongrel instance for the duration of buffering the uploaded data to disk?
Ideally the upstream mongrel instance should be free to serve other requests until nginx has saved the entire file to disk. That would make it much more efficient.

thanks

Comment on Attributes not saving for models with attachments by Daniel

Daniel — Mon, 17 Nov 2008 07:17:34 +0000

Hey thanks for this insight I was having the same issue and I commented out line 171 in the file attchment_fu.rb located in the vendor plugin folder. Seems to have done the trick, I am only uploading images and I haven’t run into any problems yet with that one line commented out. I will post here if I do run into any troubles. Thanks again

Comment on I don’t use Foreign Key Constraints with Rails by Dylan

Dylan — Fri, 14 Nov 2008 04:45:03 +0000

Hey Nahum ! Great post.

Think it’s a matter of Application Database vs Integration Database when it comes down to it. If you’re building an application on top of an Integration Database, foreign key constraints will be very important. Most of us however build applications on top of Application Databases, so the key constraint layer isn’t necessarily as crucial.
