FreeBSD hosting
Dieser Vortrag zeigt, welchen Herausforderungen im Hosting punkt.de in der jüngeren Vergangenheit gegenüber stand und welche Änderungen gegenüber unserer 2010 vorgestellten "NanoBSD"-Architektur wir seitdem umgesetzt haben. Der proServer hat auf der Seite des Hosting-Anbieters viele der erwünschten Eigenschaften eines "Private Cloud"-Produkts, stellt sich dem Kunden aber wie ein klassischer Root-Server dar. Für Anwendungen, bei denen eine solche Plattform gefordert ist, ein unschätzbarer Vorteil gegenüber reinen Container-Lösungen, die praktisch immer eine speziell angepasste Anwendungs-Architektur benötigen.
Libcontainer: joining forces under one roof
Libcontainer is a project that aims to create a common library for container management across different technologies like Docker and LXC. It avoids external dependencies and supports multiple container types through a common API. The goal is to allow cooperation and code reuse across projects through a shared container management library. Libct is a companion C library that provides a frontend API for managing the entire container lifecycle.
Event Driven with LibUV and ZeroMQ
This document provides an overview of redesigning an algorithmic trading system to use an event-driven architecture with LibUV and ZeroMQ. It discusses flaws in the current design that assumes serial execution and neglects latency. An event-driven approach is proposed to handle parallelism and uncertainty. Components will use asynchronous interfaces to avoid blocking. A unified event loop will handle all asynchronous tasks and events. The project plan is to rewrite key modules like order processing in an event-driven way and set up a test environment for comparison with the current system. The schedule aims to make progress before the upcoming Spring Festival.
Linux logging
This document discusses various techniques for improving the speed of syslog logging in Linux/C++ applications. It recommends filtering messages at the source, using syslog to filter messages, dedicating a separate hard drive for logging, and putting syslog output in RAM instead of permanent storage for faster performance. It also lists several common syslog implementations like rsyslog and syslog-ng, and logging libraries that can be used in applications like syslog native API, Liblog4c, and Boost. Finally, it discusses using the logger utility from the command line for scripts and languages that lack integrated syslog APIs.

A Journey into Hexagon: Dissecting Qualcomm Basebands
Mobile phones are quite complicated and feature multiple embedded processors handling wifi, cellular connectivity, bluetooth, and other signal processing in addition to the application processor. Have you ever been curious about how your phone actually makes calls and texts on a low level? Or maybe you want to learn more about the internals of the baseband but have no clue where to start. We will dive into the internals of a qualcomm baseband, tracing it's evolution over the years until its current state. We will discuss the custom, in-house DSP architecture they now run on, and the proprietary RTOS running on it. We will also cover the architecture of the cellular stack, likely places vulnerabilities lie, and exploit mitigations in place. Finally we will cover debugging possibilities, and how to get started analyzing the baseband firmware—how to differentiate between RTOS and cellular functions, how to find C std library functions, and more.

Running Kafka On Pi4/ARM With Jeffrey Needham | Current 2022
Running Kafka On Pi4/ARM With Jeffrey Needham | Current 2022
Apache Kafka is starting to be requested and appears more and more on ARM technologies. In some cases, ARM can appear on a developer’s new Apple M1. It can also be found in Amazon, Azure and Oracle datacenters, giving those customers a chance to run this new processor technology, save some money, save some power, maybe save the planet. Lately, I have been working with some partners to see how Kafka runs on a bagful of Pi4s, flung into some ditch, or in the back of an F150. It turns out, with a few tweaks, Kafka on Pi is very capable and opens up a whole new field - sometimes in a field - of real-time processing at the far, disconnected edge.
This talk provides a work-in-progress update of deploying Kafka on aarch64 Linux. Although the new Apple M1 is ARMv8 based, it has a distinct flavor, or ELF format - arm64. Since much of Kafka consists of noarch rpms, or simply, a bag-o-jars, both Linux and macOS have native implementations of Java, and for Kafka Streams users, native implementations of RocksDB.
This talk is intended for an audience that is familiar with emerging hardware, compiler and OS industry trends.
Caffe + H2O - By Cyprien noel
This document proposes an in-memory file system to provide a unified abstraction for distributed computing across different devices and networks. It aims to simplify application integration and allow data to be directly placed on devices like GPUs. A prototype would use distributed mmap over Ethernet or InfiniBand to test the approach. The goal is to apply this to build a new distributed version of Caffe that could better leverage devices and frameworks like H2O through simplified pipelines rather than separate integrations.
Tizen RT: A Lightweight RTOS Platform for Low-End IoT Devices
This document provides an overview and agenda for a presentation on Tizen RT, a lightweight real-time operating system (RTOS) platform for low-end IoT devices. The presentation will cover the technology and features of Tizen RT, how it differs from other RTOS options like NuttX and TinyAra, and how to build and run applications on Tizen RT using examples like building a simple "Hello World" app. It also lists several demos that will be shown, including connecting to WiFi, running MQTT subscriptions, and controlling GPIO pins.
Janus & docker: friends or foe
This document discusses Janus, a WebRTC server, and its deployment using Docker containers. It begins by providing background on microservices and Docker. It then describes issues that can arise with Docker's default networking modes for Janus due to network-related WebRTC failures. Specifically, Docker's NAT functionality does not always behave predictably for ICE negotiations. The document recommends using dedicated IP addresses for containers to avoid these issues. It provides examples of complex Docker-based architectures for deploying Janus at IETF meetings and for recording production using Docker Swarm.

RPC allows calling methods on remote objects by marshalling parameters and unmarshalling return values. There are many challenges to RPC including unreliable networks, latency, security, and changing topologies. Smalltalk supports RPC through mechanisms like distributed events, value/reference passing, and marshaling objects to formats like JSON to enable communication across networks and between systems. Developing distributed systems requires strategies for handling issues like passing large objects efficiently and updating interfaces when remote objects change.

Webinar: Designing a schema for a Data Warehouse
Are you new to data warehouses (DWH)? Do you need to check whether your data warehouse follows the best practices for a good design? In both cases, this webinar is for you.
A data warehouse is a central relational database that contains all measurements about a business or an organisation. This data comes from a variety of heterogeneous data sources, which includes databases of any type that back the applications used by the company, data files exported by some applications, or APIs provided by internal or external services.
But designing a data warehouse correctly is a hard task, which requires gathering information about the business processes that need to be analysed in the first place. These processes must be translated into so-called star schemas, which means, denormalised databases where each table represents a dimension or facts.
We will discuss these topics:
- How to gather information about a business;
- Understanding dictionaries and how to identify business entities;
- Dimensions and facts;
- Setting a table granularity;
- Types of facts;
- Types of dimensions;
- Snowflakes and how to avoid them;
- Expanding existing dimensions and facts.
