Hi. I would like to do code refactoring: @beers = [] Beer.all.each do |beer| unless @beers.find{|c| c.brand_id == beer.brand_id} @beers << beer end break if @beers.size > 29 end So I achieved this by writing scope (on PostgreSQL): scope :with_unique_brand, select("DISTINCT ON (beers.brand_id) beers.*") Using this scope alone is working

Hello Zed ! I''ve experimented a simple but limited performance tweak in the mongrel rails loader. With the following apache 2.2 mod proxy loadbalancer setup : # Redirect all non-static requests to cluster RewriteCond %{DOCUMENT_ROOT}/%{REQUEST_FILENAME} !-f RewriteRule ^/(.*)$ balancer://mongrel_cluster%{REQUEST_URI} [P,QSA,L] We can assume that mongrel is called only when the

moronic monday (pst) question time. this may have been covered elsewhere, and emphatically shot down (and if so, I apologize), but I'm interested in using ssh-agent to decrypt data. ssh certificates are the most secure user auth token we have, and even though ssh certs aren't chainable, we routinely use them to assert identity to things other than ssh (eg. if you can present a cert that's signed by a known ca, and you can prove you have the private key that belongs to the cert, we know who you are). So it'd be nice to be able to give some data back to the client, encryp...

Hello :) Having just gone through the (admittedly simple) API of Mocha to learn how it works, I wrote a quick guide (190 lines) to help others get up to speed. I''ve attached it as RDOC and as HTML. It is a first draft - please help me improve by giving feedback ! Contents : Overview - Quick overview of Mocha Unit testing, mock object and stubs - Very quick introduction to mock

Hi all, I finally understand how lipopusenc is capable of producing chainable Opus files (in contrast to my program), and I managed to successfully implement the method [1]. Essentially, the last frame of a file is marked as a "keyframe" by disabling prediction for this frame in libopus. This encoded keyframe frame is then copied in verbatim to the next file, wit...

...delays and all, but it should be doable. IOW, it should be possible to reset the encoder before the keyframe, provided you pre-fill it correctly.

Dear all great developers. I wonder if there is any work being done or thoughts being shared regarding prepared SQL statements. Currently I am in heavy need of tuning SQL INSERTS that insert large (3MB) images into blobs. I am using rails 2.3.5 with postgres adapter and pg driver. Any information would be appreciated.

Hi Jean-Mark, thank you for your answer! Yes, you understood my question correctly. I was just about to compose a reply to my original question, where I described how I solved my problem. As you've already suggested, I've switched to Ogg/Opus, which is better supported, but does not work with the Media Source Extensions. I'll have a look whether disabling prediction will help with
