Books

Concepts-Techniques-Models-Computer-Programming CMT это известная книжка CMT, за которой слава закрепилась не хуже чем у SICP

это из этой книжки классификация различных парадигм Если присмотришься, то увидишь, что Oz поддерживает большинство вариаций (с этой целью его и конструировали, чтобы можно было наглядно продемонстрировать различные подходы в одном языке)

// NOTE:
// All mixins for the 2009 spec have been written assuming they'll be fed property values that
// correspond to the standard spec.  Some mixins can be fed values from the 2009 spec, but don't
// rely on it.  The `legacy-order` mixin will increment the value fed to it because the 2009
// `box-ordinal-group` property begins indexing at 1, while the modern `order` property begins
// indexing at 0.

// if `true`, the 2009 properties will be emitted as part of the normal mixin call

Введение

Начать стоит отсюда. Не пугайтесь то, что это книга по незнакомой OS, эти термины практически везде одинаковые и здесь они изложены в понятной для начинающих форме.

http://www.qnx.com/developers/docs/6.4.1/neutrino/getting_started/s1_procs.html

Прочесть нужно треть главы до подраздела "Starting a process", если С не пугает, читайте полностью. После прочтения вы будете понимать, что такое process, thread, mutex, priorites, semaphores, scheduler, contex-switch, kernel states.

Zero downtime deploys with unicorn + nginx + runit + rvm + chef

Below are the actual files we use in one of our latest production applications at Agora Games to achieve zero downtime deploys with unicorn. You've probably already read the GitHub blog post on Unicorn and would like to try zero downtime deploys for your application. I hope these files and notes help. I am happy to update these files or these notes if there are comments/questions. YMMV (of course).

Other application notes:

• Our application uses MongoDB, so we don't have database migrations to worry about as with MySQL or postgresql. That does not mean that we won't have to worry about issues with the database with indexes being built in MongoDB or what have you.
• We use capistrano for deployment.

Salient points for each file:
