I need to store records in a key value store, and I have considered XML, JSON, or YAML, and pretty much decided on YAML. However, I am wondering how this will perform when searching through millions of records as alot of text processing is needed. Would it be better to use individual keys for differents columns or use YAML. For example,...
Using OpenCV, saving a CvMat structure into a YAML file on the disk is easy with CvMat* my_matrix = cvCreateMat( row_no, col_no, CV_32FC1 ); cvSave("filename.yml", my_matrix); However, I couldn't find an easy way to read the saved files back from the disk. Is there function in OpenCV that can handle this and create a CvMat structure...

I have code that relies heavily on yaml for cross-language serialization and while working on speeding some stuff up I noticed that yaml was insanely slow compared to other serialization methods (e.g., pickle, json). So what really blows my mind is that json is so much faster that yaml when the output is nearly identical. >>> import ya...

I'm trying to write a new entry to a rails database.yml and for some reason I'm getting quotes around this entry db_yml => {'new_env' => {'database' => 'database_name', '<<' => '*defaults' }} File.open("#{RAILS_ROOT}/config/database.yml", "a") {|f| YAML.dump(db_yml, f)} returns --- new_env: database: database_name "<<": "*defa...
Hi, I am completely stumped at the nature of this problem. We export data from our application into a 'cleaned' YAML file (stripping out IDs, created_at etc). Then we (will) allow users to import these files back into the application - it is the import that is completely bugging me out. In development, YAML::load_file(params[:uploaded...

This is at the framework level, not dealing directly with CSS, so posting to SO. I just learned about the existence of CSS frameworks. 960 Grid System seems pretty awesome, then I found Blueprint, which seems to do the same thing and more. Is there a better word than "framework" to categorize this? Are there any other products in this...

I have some big problems with symfony and doctrine at the beginning of a new project. I have created database diagram with mysql workbench, inserted the sql into phpmyadmin and then I've tried symfony doctrine:build-schema to generate the YAML schema. It generates a wrong schema (relations don't have on delete/on update) and after this I...
