OSCamp #4 on Foreman | CLI tools with Foreman by Martin Bačovský

Like many others, WordPress has been my personal blogging tool for a long time. A powerful tool for easy publishing! That is what everyone wants. Large sites like TechCrunch and TheNextWeb use it exactly for that reason. And more enterprises seem to discover it as good solution to their too-expensive publication tools. But keeping those WordPress instances running requires skills and knowledge. Because of WordPress extendibility and its very active community, you can do this too. This tutorial will teach you how use Ansible, Composer, WP-CLI, WP REST API, and Elasticsearch can push WordPress from a personal blogging tool into an enterprise-worthy level application. Out with FTP based SCM ... in with automated deployment, dependency management, and utterly fast search.

The REST API is an awesome plugin to expose your data from the WordPress core. But … the standard implementation might not fit your specific case. Just like the WordPress core, you'll be able to extend it to your specific needs. I'll show you how to handle authentication, introduce caching strategies, alter custom post types, or even change the default way of communication altogether.

The document provides an overview of advanced patterns in Flask including: 1. State management using application and request contexts to bind resources like databases. 2. Resource management using teardown callbacks to commit transactions and release resources. 3. Customizing response creation by passing response objects down a stack or replacing implicit responses. 4. Server-sent events for real-time updates using Redis pub/sub and streaming responses. 5. Separating worker processes for blocking and non-blocking tasks using tools like Gunicorn and Nginx. 6. Signing data with ItsDangerous to generate tokens and validate user activations without a database. 7. Customizing Flask like adding cache bust

HA websites are where the rubber meets the road - at 200km/h. Traditional separation of dev and ops just doesn't cut it. Everything is related to everything. Code relies on performant and resilient infrastructure, but highly performant infrastructure will only get a poorly written application so far. Worse still, root cause analysis in HA sites will more often than not identify problems that don't clearly belong to either devs or ops. The two options are collaborate or die. This talk will introduce 3 core principles for improving collaboration between operations and development teams: consistency, repeatability, and visibility. These principles will be investigated with real world case studies and associated technologies audience members can start using now. In particular, there will be a focus on: - fast provisioning of test environments with configuration management - reliable and repeatable automated deployments - application and infrastructure visibility with statistics collection, logging, and visualisation

https://2018.zeronights.ru/en/reports/reverse-proxies-inconsistency/ Modern websites are growing more complex with different reverse proxies and balancers covering them. They are used for various purposes: request routing, caching, putting additional headers, restricting access. In other words, reverse proxies must both parse incoming requests and modify them in a particular way. However, path parsing may turn out to be quite a challenge due to mismatches in the parsing of different web servers. Moreover, request converting may imply a wide range of different consequences from a cybersecurity point of view. I have analyzed different reverse proxies with different configurations, the ways they parse requests, apply rules, and perform caching. In this talk, I will both speak about general processes and the intricacies of proxy operation and demonstrate the examples of bypassing restrictions, expanding access to a web application, and new attacks through the web cache deception and cache poisoning.
