The document outlines the steps to set up SSH key-based authentication between an Ansible control node and two target nodes to enable Ansible to configure the target nodes without passwords. It involves generating public/private key pairs on the control node, adding the public key to each target node's authorized_keys file, and restricting password logins for security.
The document discusses the Rack web server interface used in Ruby and provides examples of using Rack to build simple web applications that respond with "Hello World". It also shows how middleware can be used in Rack applications to add functionality like response timing.
This is a presentation I gave in Helsinki Node.js meetup (check http://helnode.io).
I have been implementing a realtime communication service with Ruby during my previous assignment. I've used Rails and lower level Ruby frameworks such as Sinatra and Resque workers.
I do like especially the Rack, since it enables building an efficient server stack. You can throw in middleware for throttling, authentication and for other tasks quite easily.
Ruby was a strong candidate also for my current project. I consider the Ruby code is more readable than JavaScript. However, once I understood what ECMAScript 6 brings in, I was sold to Node.js. Generators will enable actually very similar implementations than the Ruby's Rack stack. In my opinion, JavaScript will finally become mature with JS1.7 as the "callback spaghetti" will be soon history."
Redis provides several tools to achieve atomicity of operations. Single commands are atomic by default. Pipelining ensures commands are executed in order but is not fully atomic. Transactions using MULTI and EXEC are fully atomic but don't allow command chaining. Lua scripting allows complex multi-step operations to be run atomically and allows command results to be passed between operations.
This document summarizes the new features and changes in version 0.7 of the Socket.IO library. Key updates include a complete API rewrite, support for multiple processes, a new messaging protocol with flags for different message types, acknowledgments between client and server, namespacing to allow multiplexing, handshake support for sessions, shared code modules between client and server, and testing on both the client and server. The release of version 0.7 is planned for this week.

2. Improved querying HTTP API
3. Data ingestion via Syslog protocol
* Automatic parsing of Syslog fields
* Supported transports:
○ UDP
○ TCP
○ TCP+TLS
* Gzip and deflate compression support
* Ability to configure distinct TCP and UDP ports with distinct settings
* Automatic log streams with (hostname, app_name, app_id) fields
4. LogsQL improvements
● Filtering shorthands
● week_range and day_range filters
● Limiters
● Log analytics
● Data extraction and transformation
● Additional filtering
● Sorting
5. VictoriaLogs Roadmap
● Accept logs via OpenTelemetry protocol
● VMUI improvements based on HTTP querying API
● Improve Grafana plugin for VictoriaLogs -
https://github.com/VictoriaMetrics/victorialogs-datasource
● Cluster version
○ Try single-node VictoriaLogs - it can replace 30-node Elasticsearch cluster in production
● Transparent historical data migration to object storage
○ Try single-node VictoriaLogs with persistent volumes - it compresses 1TB of production logs from
Kubernetes to 20GB

Why Apache Kafka Clusters Are Like Galaxies (And Other Cosmic Kafka Quandarie...Paul Brebner
Closing talk for the Performance Engineering track at Community Over Code EU (Bratislava, Slovakia, June 5 2024) https://eu.communityovercode.org/sessions/2024/why-apache-kafka-clusters-are-like-galaxies-and-other-cosmic-kafka-quandaries-explored/ Instaclustr (now part of NetApp) manages 100s of Apache Kafka clusters of many different sizes, for a variety of use cases and customers. For the last 7 years I’ve been focused outwardly on exploring Kafka application development challenges, but recently I decided to look inward and see what I could discover about the performance, scalability and resource characteristics of the Kafka clusters themselves. Using a suite of Performance Engineering techniques, I will reveal some surprising discoveries about cosmic Kafka mysteries in our data centres, related to: cluster sizes and distribution (using Zipf’s Law), horizontal vs. vertical scalability, and predicting Kafka performance using metrics, modelling and regression techniques. These insights are relevant to Kafka developers and operators.

ktera nam poskytne aplikacni programatorske rozhrani API pro volani funkci
poskytovane touto knihovnou. API predepisuje zpusob volani funkci dane knihovny
ze zdrojoveho kodu (meho) programu. V soucasne dobe je nejrozsirenejsim
standardem API OS Win32 od Microsoftu a POSIX(IEEE). Windows API (WinAPI, Win32)
je API vyvinute Microsoftem pro OS MS Windows. Vsechny programy v MS Windows musi
nezavisle na pouzitem programovacim jazyce komunikovat prostrednictvim standardu
WinAPI (Win32), ktery obsahuje zakladni funkce. Funkce jsou implementovany v
zakladnich systemovych DLL kernel32.dll, user32.dll, gdi32.dll. Vyuzijeme pouze
API funkce knihovny user32.dll a kernel32.dll
Poznamka [2.] Bude potreba naistalovat program MSVC Spy++ nebo WINSPECTOR SPY a
detekovat nazvy tridy na bezicich instancich oken a procesu, nazvy buttonu…
