while learning reverse engineering, got know assembly best way see , attack closed source software. why languages c/c++ needs convert code assembly, why doesn't directly convert machine language. secondly why necessary map code sections (like .stack,.bss) @ same location (virtual) every time? some compilers, in time compilers example, output machine code. in general easier debug compiler human examining assembly language rather machine code. extent "unix way" adding layer existing tools, etc. in case assembler , linker need exist target platform, understood argument. can generate assembly language , debug visually, , use existing assembler , linker turn usable machine code.

the query below, using cakephp's i18n table, takes around 1000ms run. i18n table large - has around 600,000 rows. have default indexes on table, per cake schema. how can speed queries up? caching them possible when cache needs cleared these queries run, , slow down performance quite noticeably. select `category`.`id`, `category`.`slug`, `category`.`name`, `category`.`description`, `category`.`head_title`, `category`.`display_title`, `category`.`category_count`, `category`.`product_count`, `category`.`parent_id`, `category`.`lft`, `category`.`rght`, `category`.`sort_order`, `category`.`created`, `category`.`modified`, `category`.`image_processed`, ((rght - lft) = 1) `category__is_child`, (`i18n__name`.`content`) `category__i18n_name`, (`i18n__description`.`content`) `category__i18n_description`, (`i18n__slug`.`content`) `category__i18n_slug`, (`i18n__head_title`.`content`) `category__i18n_head_title`, (`i18n__meta_description`.`content`) `category__i18n_meta_description`,...
